INTRODUCTION

The Central Pollution Control Board (CPCB) was constituted as Central Board for Prevention and Control of Water Pollution (CBPCWP) on 22nd September, 1974 under the provisions of The Water (Prevention & Control of Pollution) Act, 1974, and later under Water (Prevention & Control of Pollution) Amendment Act 1988 (No. 53 of 1988) its name was amended as Central Pollution Control Board. The main functions of CPCB, as spelt out in The Water (Prevention and Control of Pollution) Act, 1974, and The Air (Prevention and Control of Pollution) Act, 1981, are: (i) to promote cleanliness of streams and wells in different areas of the States through prevention, control and abatement of water pollution; and (ii) to improve the quality of air and to prevent, control or abate air pollution in the country.

The Central Pollution Control Board has been playing key role in controlling pollution by generating relevant data, providing scientific information, rendering technical inputs for formation of national policies and programmes, training and development of manpower, through activities for promoting awareness at different levels of the Government and Public at large. The Central Board has enlisted thrust areas requiring immediate attention and assisted government to formulate National Plans and to execute these appropriately through continuous follow up and review.

AIR AND WATER QUALITY MONITORING NETWORK

WATER QUALITY ASSESSMENT

1) WATER QUALITY MONITORING NETWORK

Water quality monitoring is an important exercise, which helps in evaluating the nature and extent of pollution control required, and effectiveness of pollution control measures already in existence. It also helps in drawing the water quality trends and prioritising pollution control efforts. Keeping this in view, the Central Pollution Control Board in collaboration with State Pollution Control Boards has established the water quality network comprising of 784 stations spread over the country. The monitoring is done on monthly or quarterly basis in surface waters and half yearly in case of groundwater.

Monitoring Results

The monitoring results obtained during 2002 indicate that organic pollution continues to be the predominant form of pollution at aquatic resources. The organic pollution measured in terms of bio- chemical oxygen demand (BOD) & coliform count gives the indication of extent of water quality degradation. It is observed that nearly 60% of the observations out of 5000 observations, are having BOD recording less than 3 mg/l, 20-25% between 3-6 mg/l & 15% above 6 mg/l. Similarly total & fecal coliform, which indicate presence of pathogens in water, are also of major concern. Nearly half of the observations are having coliform more than 500 Nos./100 ml.

Water Quality Trend

An attempt is made to plot trends of percentage of observations obtained during last 10 years in different levels of pollution with respect to BOD & coliform. The trend is presented in Fig.5.1.

It is clear from the Fig.5.1 that there is a increasing trend in percentage of observations having BOD below 3 mg/l & colform below 500 Nos./100 ml. This indicate that there is a gradual improvement in water quality. However the percentage of observations having BOD more than 6 mg/l & coliform more than 5000 Nos./100 ml is also increasing.

This is due to the shifting of moderately polluted water bodies to higher level of pollution as clear from the decreasing trend in the percentage of observations having BOD between 3-6 mg/l and coliform between 500-5000 Nos./100 ml.

2) POLLUTED RIVER STRETCHES IN INDIA

The Central Pollution Control Board (CPCB) in collaboration with concerned State Pollution Control Boards is carrying out water quality monitoring at 784 locations. The monitoring data are compiled, analysed and compared with desired water quality in different water bodies. The monitoring programme helps in prioritising pollution control efforts, establishing water quality trends and evaluating effectiveness of pollution control measures already in existence. In order to prioritise the pollution control efforts, CPCB identifies areas of high priority based on the severity of the problem. In 1988-89, CPCB identified 10 problem areas and 10 polluted river stretch to concentrate the pollution control efforts the list of polluted stretches formed the basis for formulation of River Action Plan of the National River Conservation Directorate. The list was further extended based on increasing pollution problem in our country. The water quality data of Year 2000 and 2001 analysed and 86 polluted water bodies are identified. Among these 71 are rivers and 15 lakes and tanks (Table 5.1). These water bodies are not meeting the desired level of water quality for defined uses with respect to Bio-chemical Oxygen Demand. In the present exercise, those water bodies having BOD more than 6 mg/l are identified as polluted water bodies.

3) WATER QUALITY OF MAJOR RIVERS

Water quality profiles of 14 major rivers as studied have been presented in Annexure V. For this purpose, the criteria parameters considered are DO, BOD and Total Coliforms. pH has not been plotted as it remained within desired levels at almost all monitored locations. The significant observations about the major rivers are presented below:

River Baitarni: DO values of this river stretch are meeting the desired class throughout the year. In case of BOD, the entire river stretch under monitoring is not meeting the desired class. Average values in first two locations are within the desired class for both BOD and Total Coliform, thereafter from Jajpur onwards it is never meeting the desired class for BOD. In case of Total Coliform, average values are beyond the desired class due to higher concentration up to 11,000 Nos./100ml in the stretch from Anandpur to Chandbali and at Dhamra, it has touched 21,000 Nos./100ml.

River Brahmani: DO values of this river stretch are meeting the desired class (3 mg/l) except one value in the month of July at Raurkela D/s. In case of BOD, there is much fluctuation in values. BOD values are observed violating the desired class at all the locations and touched 5 mg/l and 6 mg/l at D/s Pamposh and Kamalanga respectively. Total Coliform values are violating the desired class at D/s Pamposh, Rourkela D/s, Samal, Talcher U/s, Kamalanga, Dhamasala & Pattamundai. At other locations it is well within the limit of desired class

River Brahmaputra : DO values of water in this river stretch are meeting the desired class throughout the year. BOD values are meeting the desired class in the entire stretch except at Kherghat in the month of December (3.7 mg/l). Total coliform values were observed violating the desired class at all the locations.

River Cauvery : On an average DO & BOD values have been found meeting the desired class. But DO values were not within the desired level at Erode in the months of January (3.8 mg/l) & October (3.5 mg/l), at Mohanur in the month of August (0.5 mg/l), at Tiruchirappalli U/s in the month of May (4.8 mg/l), at Tiruchirappalli D/s in the months of January (3.8 mg/l), September (3.5 mg/l) and October (4.3 mg/l), at Trichy in the month of February (4.7 mg/l), at Pitchavaram all months except February & March and at Near Boarder in the month of March (1 mg/l). It is observed that BOD values was exceeding the desired limit at Erode, Mohanur, Thirumukkudal, Musiri, Tiruchirappalli U/s, Tiruchirappalli D/s, Trichy, Thanjavur, Pitchavaram and Near Boarder. Total Coliforms values were well within the desired class except at Napokulu Bridge.

BOD values were meeting the desired class after Kurundwad except at Thangadi for all the months having maximum of 3.6 mg/l and Hamsala Deevi in the months from May to September having maximum concentration of 10.5 mg/l. BOD values were not meeting the desired class in the stretch from Mahabaleswar to Kurundwad even in a single month monitored during the year.

River Mahanadi : In the entire stretch from Rudri U/s to Paradeep D/s, all DO values were meeting the desired class throughout the year. BOD values were observed violating (during certain months) at five locations at Hirakund Reservoir, Sambalpur U/s, Sambalpur D/s, Sonepur D/s and Cuttack D/s. At other locations it is meeting the desired class. Total Coliform values were not meeting the desired class in the stretch at Hirakud Reservoir, Sambalpur U/s, Sambalpur D/s, Cuttack U/s and Cuttack D/s. Total Coliforms values were meeting the desired class at other locations.

River Narmada : DO values are meeting the desired class in the entire stretch except at Amarkantak in the months of February, April, May, June, August with minor deviations. In case of BOD & Total Coliforms, it is meeting the desired class in the stretch from D/s of Omkareshwar till end of the stretch upto Bharuch except Total Coliforms at Garudeshwar. In addition to this, all the values of Total Coliforms were meeting the desired class at Amarkantak, Mandla, Narsinghpur and Hoshangabad D/s.

River Penner : DO values are meeting the desired class at all the locations throughout the year. In case of BOD, minor violations (up to a maximum of 3.6 mg/l) in all the monitored locations were obsereved.

River Sabarmati : DO Values are violating the desired class at Railway Bridge in the months of January (3.0 mg/l), June (0.4 mg/l), July (1.3 mg/l), August (1.2 mg/l), October (1.4 mg/l), November (4.0 mg/l) and December (3.0 mg/l). At the same time maximum values of 19 mg/l in the month of April and 13 mg/l in the month of March were also observed due to eutrophication effect. At other locations, it is well within the limit of desired class. BOD and Total Coliform values were violating the desired class at all the monitored locations. At V.N. Bridge, BOD is violating in all the months touching the level of 517mg/l in the month of March and Total Coliforms value is 4.6 million MPN/100ml in the month of March at Railway Bridge and at Miroli Taluka. The Sabarmati river is probably the heaviest polluted river.

River Subarnarekha : DO & BOD values are meeting the desired class except BOD in the months of February (3.2 mg/l), April (4.6 mg/l) and May (3.8 mg/l) at Tata Nagar. Total Coliforms values were not meeting the desired class at all locations except at Chandil Bridge and observed more than 24,000 MPN/100ml at Ranchi, Jamshedpur and Tata Nagar.

River Tapi : DO values were found meeting the desired class at all the locations except in the month of April (5.8 mg/l) at Ajnand Village. BOD values were observed violating at all the locations except at Nepanagar. In addition to this, BOD values are always observed violating throughout the year at Ajnand Village, Bhusawal U/s and Uphad Village. Total coliform values were found meeting desired class at two locations i.e. Bhuswal U/s and Uphad Village.

4) SEWAGE MANAGEMENT IN GANGA BASIN The major source of organic pollution in fresh water bodies is sewage because the cities and towns did not have adequate sewage treatment facilities. Untreated or improperly treated human wastes disposed into aquatic resources. At downstream, other city's draw water for its water requirements. This constitute a big public health hazard in terms of their potential for spreading water borne diseases.

As per the recent estimate, out of 22,900 MLD of wastewater generated in the Ganga basin, only about 5,900 MLD (26%) is treated while as much as 17,000 MLD is disposed untreated. Twenty-seven cities have only primary treatment facilities and forty-nine have primary and secondary treatment facilities. The level of treatment available in cities with existing treatment plant varies from 2.5% to 89% of the sewage generated.

The river Ganga is the largest river in the country having catchment area of 861,404 square kilometres, covering 26.2 percent of total geographical area of the country. The river watershed spread over ten States, namely:- Uttaranchal, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Himachal Pradesh, Rajasthan, Haryana, Madhya Pradesh and Delhi.

Urban population consisting of Class I Cities and Class II Towns in the Ganga basin is 57 million (as per 1991) which is projected to be over 72 million in 2002. There are 101 Class I cities and 122 Class II towns in the basin. The recent survey of Class I and Class II cities indicate that about 8,250 MLD wastewater is generated in the Ganga basin (Table 5.2), out of which treatment facilities are available only for 3,500 MLD of wastewater. Out of 3,500 MLD treatment capacity, 880 MLD has been created under Ganga Action Plan, 720 MLD under Yamuna Action Plan and about 2,189 MLD has been created by Delhi Government for restoration of water quality of river Yamuna. The treatment facilities at 48 additional towns along the Ganga and 23 towns on its tributaries/sub-tributaries are being created under Ganga Action Plan Phase-II and National River Action Plan. It is expected that after completion of these plans, an additional treatment capacity of about 1,500 MLD will be created. However, still there is a large gap between the wastewater generation (8,250 MLD) and treatment (3,500 MLD).

Sewage Treatment Plants under the Ganga Action Plan

Central Pollution Control Board carried out a detailed study of Ganga river basin in 1983-84 which was culminated into an action plan to restore its water quality. The action plan was accepted by the Government of India for implementation in 1985-86 and on 14 th June 1986 an ambitious plan called the Ganga Action Plan was launched with following objectives:

• Pollution abatement to improve the water quality, interception, diversion and treatment of domestic sewage entering into the river; • Control of non-point pollution from agricultural run off, human defecation, cattle wallowing and throwing of unburned and half burnt bodies into the river; • Research and development to conserve the biotic diversity of the river to augment its productivity; and, • To act as trend setter for taking up similar action plans in other grossly polluted stretches in other rivers. In order to achieve the objectives of improving the water quality, 261 scemes covering 25 class I cities of Uttar Pradesh, Bihar and West Bengal were taken up. It was targeted to intercept, divert and treat 873 million litres per day (MLD) of domestic wastewater, out of 1340 MLD being generated from the 25 class I cities in the states of Uttar Pradesh, Bihar and West Bengal. For controlling industrial pollution, 68 grossly polluted units discharging 260 MLD industrial wastewater into the river were taken up for close monitoring and forcing the industries to set up effluent treatment plant.

The Sewage Treatment Plants (STPs) were either upgraded or constructed to treat the domestic sewage by adopting treatment technologies, such as low cost waste stabilisation ponds, conventional Activated Sludge Process (ASP) Trickling Filter (TF) and Upflow Anaerobic Sludge Blanket (UASB) treatment systems (Table 5.3).

• Out of 35 STPs planned under GAP Phase I (3 STPs in Uttaranchal, 10 STPs in Uttar Pradesh, 7 STPs in Bihar, and 15 STPs in West Bengal), 32 are commissioned and 29 were found functioning. • Adequate fund allocation for Operation & Maintenance of STPs is not provided particularly in States of Bihar and U.P. • A number of sewage treatment plants are under-loaded e.g. Jajmau, Kanpur; DLW, Varanasi; Naini, Allahabad and some are over-loaded e.g. Dinapur and Bhagwanpur at Varanasi. • Several treatment plants (STPs) need upgradation. These include all the STPs of Bihar, Swargashram at Rishikesh; Kankhal, Haridwar; Jajmau in Uttar Pradesh and Bhatpara, Titagarh, Panihati in West Bengal. • Out of 1345 MLD sewage joining river Ganga as estimated during 1985, the STPs were planned for treatment of only 875 MLD sewage. Since then, the volume of sewage has increased significantly. • In Bihar, the treatment plants at Karmali Chak (Patna), and Munger are yet to be constructed. Similarly, STP at Chapra and Bhagalpur are under-designed as their capacity is 2 MLD & 11 MLD respectively against 8.74 and 28 MLD respectively. The Chapra STP is not receiving the sewage, as it is located far away (5 km) and there is siltation in the drain, which is supposed to carry sewage through gravity flow. • None of the STPs have obtained consent from the concerned State Pollution Control Boards, although it is obligatory under the Water Act, 1974. • Inadequacy of trained personnel for Operation & Maintenance work is a major shortcoming. Non-availability of uninterrupted power is another problem in most of the places. Since the STPs are biological in nature, their continuous operation is a must in order to maintain the biological growth at activated level. • In most of the cities/towns included in GAP, proper sewerage system does not exist and the sewage flows in open drains causing several problems. In rainy season, the run-off water generally mixes with sewage. Since the diversion of drains through pumping is taken care of only dry weather flow, during rainy season it cannot pump the additional load of run-off water. Thus, such interception will not be effective in controlling pollution of the river during rainy season. In many cities, the sewage is not reaching the STPs due to non-existence or non- functioning of sewage transport system. • There are 21 towns under Yamuna Action Plan, 3 under Gomti Action Plan, 12 under Damodar Action Plan, 3 under Betwa Action Plan, 3 under Chambal Action Plan and one each under river Shipra and Khan. • There are 223 cities/ towns (Municipalities/Corporation) generating significant amount of sewage in the Ganga basin. These cities/ towns generate about 8,250 MLD ( million litre per day) of wastewater, out of which about 2,460 MLD is directly discharged into the Ganga river, about 4,570 MLD is discharged into its tributaries or sub-tributaries and about 1,220 MLD is disposed on land or in low-lying areas • Out of 8,250 MLD of wastewater generated in the Ganga basin, the treatment facilities are available only for 3,500 MLD of wastewater. Out of 3,500 MLD treatment capacity, 880 MLD is created under the Ganga Action Plan, 720 MLD is created under the Yamuna Action Plan by NRCD, MoEF Govt of India and about 2,189 MLD treatment capacity is created by the Govt. of Delhi for restoration of water quality in Yamuna river.

5) MONITORING OF RIVER YAMUNA FOR ASSESSMENT OF WATER QUALITY

Central Pollution Control Board is regularly monitoring river Yamuna at 19 locations from its origin at Yamunotri to its confluence with river Ganga, under National River Conservation Directorate (NRCD) sponsored project & under National Water quality Monitoring programme. The frequency of monitoring at each location varies with the significance and approach of respective location. The frequency of monitoring is once in a year at 2 locations viz. Yamunotri and Shyama Chetti, four times a year at three locations viz. Lakhwar Dam, Dak Pathar & Allahabad, while monthly at 14 locations.

Based on the water quality characteristics, 1376 km long Yamuna river stretch can be segregated into five stretches i.e. Himalayan stretch, Upper stretch, Delhi stretch, Mixed stretch and Diluted stretch. The water quality characteristics of these stretches are depicted in Table 5.4.

As reflected from the water quality characteristics, the Delhi stretch of river Yamuna is critically polluted and having septic conditions. The mixed stretch is having both septic & eutrophic conditions. In this stretch the city is the biggest contributor of pollution to the river. The water quality of river Yamuna at Agra is deteriorating because of construction of Gokul Barrage at upstream Agra, where the water is again blocked. During year 2002, the Bio-chemical oxygen demand at Agra downstream ranged between 8-42 mg/l, with annual average of 21 mg/l whereas Total coliforms varied from 4,60,000 to 24,30,00,000 Nos./100 ml. The major reason of pollution in river Yamuna is not only discharges from domestic and industrial sources but also over-exploitation of fresh water available in the river, which is essentially required to maintain self purification capacity of the river. In the entire stretch of Yamuna River, the water quality, specially in terms of Total coliform is not conforming with respective designated criteria.

Water Quality Status of River Yamuna in Delhi

The water quality of river Yamuna from origin upto Delhi u/s Wazirabad remains fairly good most of the time, while the river stretch from downstream Wazirabad Delhi to upstream Chambal confluence carries deteriorated water quality mainly because of contribution and impact of urban centers located on its bank. Out of 341 km stretch, 22 km of Delhi segment is most polluted. The main reason of pollution in this segment is the discharge from domestic and industrial sources. The Central Pollution Control Board is regularly monitoring Yamuna on monthly basis in Delhi segment at three locations i.e. Palla, Nizamuddin barrage and Okhla barrage. In addition, monitoring of 22 drains being undertaken regularly (20 drains joining the River Yamuna directly while two drains joins the canals), which are the major source of pollution to the river. The total calculated discharge of these 22 drains is approx. 47.73 m 3 /sec, which contribute 259.61 tonnes of BOD load per day. From the total discharge from these drains, Yamuna receives more than 90% wastewater, while the wastewater contributed by other two drains joins canals. Accordingly, out of total BOD load of 259.61 tonnes, Yamuna receives 231.20 tonnes of BOD load per day and rest received by the canals (Table 5.5).

The Delhi segment of river Yamuna has oligotrophic head and saprobic tail end and characterized by high bacterial load (except at Palla location its appearance is cloudy) having high BOD with strong disagreeable odour. There is significant contrast in the water quality status of the river between upstream Wazirabad barrage (Palla) and downstream Wazirabad (Nizamuddin bridge and ) (Table 5.6). The anaerobic condition in river is frequently reflected by masses of gaseous sludge rising from the bottom and floating at the water surface.

Delhi generates about 3,600 MLD of wastewater, out of which treatment facility is available for only 2,109 MLD. It is observed that there is continuous effort by the Government of National Capital Territory of Delhi to augment the treatment capacity. However, the exponential population growth is nullifying the results.

Twelve towns in Haryana and 8 Towns in Uttar Pradesh are included for setting up of sewage treatment plants under Yamuna Action Plan. Two sewage treatment plants in Delhi also been constructed under this plan at Sen Nursing Home Drain and Delhi Gate Drain with a design capacity of 10 MLD each. Under the plan 34 STP's are commissioned with a treatment capacity of 743.25 MLD (Table 5.7).

Total Coliforms and Faecal Coliforms.

7) WATER QUALITY ASSESSMENT THROUGH BIO-MONITORING OF MAJOR WETLANDS IN WILDLIFE HABITATS OF INDIA

The wetlands are the richest and most biologically diverse ecosystem. Many wetlands in the country support spectacular diversity of wildlife. Some are centers of rare, threatened and endangered species. Many of them are home of rich variety of mammals, birds, amphibians and reptiles. There is also a phenomenal diversity of insects associated with wetlands. In recent years, wetlands have been the focus of innumerable studies. This is also the only ecosystem type to have its own international convention, namely, the convention on wetlands of International importance especially as waterfowl habitats better known as the Ramsar convention to which India is a signatory.

The high biological productivity and bio-diversity values of wetlands, and the sustenance that these habitats provide to communities, have long been realized. However, the contribution of wetlands in maintaining the food chain in open waters, and in providing a variety of services such as; water quality improvement, flood control, and ground water recharge, among others been emphasized in the context of conservation. With the increase in human population, pressure on land for agriculture, urban and industrial expansion, wetland habitats in India have been over exploited. In many cases, such human excesses have greatly reduced bio-diversity, thus upsetting the ecological balance decreasing the values of wetlands. The need and importance of wetlands in water quality management has been greatly realized for improving water quality and wetlands species as bio-indicators. The project studies are undertaken by Central Pollution Control Board at various wetlands in the country with following major objectives:

• Bio-monitoring of wetlands in wildlife ecosystem will help in prediction and detection of ecological effects to protect rare and endangered biotic species in cost-effective manner. • Generate base line data on bio-monitoring of water bodies being used for propagation of wildlife habitats in India. • Training / interaction to local authorities, NGO's other institutions such as forest Department State Pollution Control Boards and other concerned organizations. During the reporting year the bio-monitoring studies have been undertaken in vicinity of wetlands of important wildlife habitats in states of Andhra Pradesh, Arunachal Pradesh, Assam, Bihar, Delhi, Uttar Pradesh, Haryana, Punjab, Rajasthan and Meghalaya (Table 5.10).

8) WATER QUALITY ASSESSMENT OF RAW WATER INTAKE SOURCES AT WATER TREATMENT PLANTS IN NCT – DELHI

The estimated water availability at NCT – Delhi from surface water sources viz. Yamuna, Ganga & Western Yamuna Canal is about 1150.2 mcm. The Yamuna river contributes a substantial part to this. Of the total 724 mcm water available in Yamuna river, (NCT Delhi share) the flood water is about 580 mcm, of which more than 50% could not being utilized but flows out of Delhi during monsoon season. It will be a definite foresight to trap and store this water for use during lean summer season.

The installed capacity of water treatment plants to meet drinking water requirements of Delhi is 631 MGD as on 31.3.2001. To mitigate drinking water scarcity, the water supply is augmented through ground water abstraction from river bed of Yamuna through Ranny wells. A substantial quantity of ground water is being withdrawn by private houses, hotels, hospitals, etc. At the end of 9th five year plan, the installed capacity of water treatment is proposed to be augmented to 980 MGD. The major part of potable water was treated at two water treatment plants installed and commissioned during British period viz. Chandrawal and Wazirabad on River Yamuna till the year 1993. Later the water treatment was augmented by installation of Haiderpur and Bhagirathi Water Treatment Plant. The raw water at Bhagirathi Water Treatment Plant is drawn from Upper Ganga Canal, which originates from Har-Ki-Pouri at Haridwar. After travelling almost 160 km from Haridwar upto Murad Nagar, the water from Upper Ganga Canal is drawn into a by-pass to Muradnagar Head works and from there to the Water Works, Delhi through 25 km conduit pipes of 2800 mm dia and 3250 mm dia. The part of the raw water at Bhagirathi Water Works is also drawn from river Yamuna at Wazirabad. The water from river Yamuna and Upper Ganga Canal are collected separately and mixed together before treatment at Bhagirathi Water Treatment Plant.

Two more water treatment plants were commissioned at Haiderpur in 1993 and 1995 on tail tributary of Western Yamuna Canal. Okhla Water Works is based on biological treatment process in Delhi using Ranny well water from the river bed of Delhi stretch of Yamuna. The water treatment capacities of these treatment plants had been augmented from time to time. The water treatment plants, their installed water treatment capacities & raw water sources is presented in Table 5.14.

With ever increasing population and rapid industrialization, the demand of fresh water is increasing day by day and simultaneously there is a growing threat to water quality deterioration in surface water sources, which are being used as raw water source for drinking water supply. Looking into the seriousness of the problem, the Central Pollution Control Board (CPCB) has conducted regular studies on water quality at raw water sources in NCT - Delhi, River Yamuna, Western Yamuna Canal (WJC) and Upper Ganga Canal, which are the main surface water sources for drinking water supply in Delhi. The findings on physico-chemical quality of raw water are presented in Tables 5.15, 5.16 and 5.17 ahead:

9) GROUNDWATER SURVEY

Groundwater Survey for the Problem areas

In the 29th Conference of the Chairmen & Member Secretaries of Central Board and State Pollution Control Boards, it was decided that an integrated approach towards environmental management was necessary for pollution related matters in the problem areas. CPCB had initially identified 22 problem areas and subsequently two more problems areas were identified. CPCB had conducted a major groundwater quality monitoring program at 22 problem areas during year 1994 and the findings were brought out as CPCB publications series GWQS/1 to 4 / 1995-96.

In the current programme, it is proposed to conduct another round of groundwater quality monitoring at all the identified problem areas through Zonal Offices of CPCB. The reports will be brought in a staggered manner and the first part is under finalisation, wherein the data will be interpreted along with data of surveys already available with the Central Ground Water Board. The participating agencies are listed in Table 5.18 below.

2. Bacterial contamination was observed at all the five locations. 3. Fluoride levels were found quite low in most of the samples taken, about 65% of the samples in 2001-2002 reported values less than 0.5 mg/l. The data received from Central Ground Water Board for the year 1999-2000 indicated fluoride values from 0.18 to 0.45 mg/l at all the locations i.e. Piala, Bhiringi, Banscopa, Deshbandhunagar and Durgapur Barrage. 4. The concentrations of heavy metals were less than the stipulated values except for iron at the dugwell at Palasdiha . 5. The reported values for DDT were the most prominent, compared to other pesticides.

Vapi, Gujarat

Vapi in Gujarat is one of the biggest industrial estates with 1,800 industrial units in about 1,140 hectares of land. The groundwater samples collected from this problem area reveal that the Total Dissolved Solids were exceeding the limit of 500 mg/l and total hardness values were within the limit. The values of sulphate and nitrite were within the limit, but the conductivity values were ranging between 1,880 to 1,940 µmhos/cm, indicating contamination from surface pollutants. The measured values of chloride and fluoride were within the limit at IOC Godown, but values were exceeding at Charwad Road Station. The counts of Total Coliform and Fecal Coliform were below detectable limit except at IOC Godown during first round. There is a possibility of sewage contamination at this point. The concentrations of magnesium and calcium were exceeding at IOC Godown. Groundwater quality of Vapi has been presented in Fig 5.2.

Fig 5.2 Groundwater Quality of Vapi, Gujarat Ankleshwar, Gujarat

The groundwater samples collected from Ankleshwar, another problem area in Gujarat, reveal that the Total Dissolved Solids were high in concentration, and total hardness was exceeding the limits. The values of sulphate and chloride were exceeding the limits. The value of nitrite was observed within the limit near CETP and Bharuch Naka. The concentration of fluoride was within the limit. Total Coliform and Faecal Coliform were not detected at Piraman School, however, both were found at Bharuch Naka. Total coliform was present near CETP, but faecal coliform could not be detected. The measured sodium values were 67-400 mg/l near CETP, 490-610 mg/l at Piraman School and 790-870 mg/l at Bharuch Naka. The groundwater quality data has been depicted in Fig 5.3. Fig 5.3 Groundwater Quality in Ankleshwar, Gujarat

Najafgarh Drain Basin Area, Delhi

Three rounds of Samplings were undertaken at 15 locations on the Najafargh drain Basin area. Analysis of around 40 physico-chemical parameters including Heavy Metals and Pesticides were completed .

North Arcot District (Vellore District), Tamil Nadu.

There are around 450 tanneries are located and functioning in Vellore District. 356 tanneries are connected to common effluent treatment plant. 95 tanneries are having individual treatment plant. Tannery treated/untreated effluent discharges into land, river etc. and contaminate the ground water and river water. To assess the impact of tannery effluent on ground water, 14 ground water samples were collected in Vellore District. The study revealed that salt content and heavy metal content, Total Coliform and Faecal Coliform content are high. This may be due to tannery industries and dyeing industry treated and untreated effluent discharges to the land and ground water source.

Manali - Chennai, Tamil Nadu.

Many medium scale and large scale industries are located in Manali Industrial area in Chengalpet District. The Industrial area is 20 KM from Chennai. The industries discharging, treated/untreated effluent into Buckingham Canal and Bay of Bengal. In order to study the impact of industries on ground water quality, 6 sampling stations were selected for study. The ground water sampling were carried out in the month of September, 2001, January, 2002 and May, 2002. The study results indicates that the ground water of the area was polluted in respects with salinity of ground water, TDS, Total Hardness & Bacteriological parameters.

Bhadravathi, Karnataka.

The ground water quality at Bhadravathi, critically polluted area in Karnataka state was monitored for the months of September, 2001, January, 2002 and may, 2002 at different locations namely Amirjan Colloy, Baba Halli and Machenahalli. These all three stations ground water bore well is mainly used for drinking and domestic purposes. The Bhadravathi ground water was found with high TDS, Total Hardness, Chlorides and Microbial presence and shows that the ground water has become polluted and not fit for potable use.

Vishakapatnam, Andhra Pradesh.

There were 7 Nos. ground water samples stations selected. Ground water samples were collected in the months of September, February, 2002 and October, 2002 by CPCB, South Zonal Office, Bangalore and analysed by Andhra Pradesh Pollution Control Board Laboratory. Most of the ground water stations were found polluted by Total Coliform. Mindi, Pedchantya, R.K. Puram station are highly polluted area and Nitrate, Sulphate were very high. Vishakapatnam do not have adequate sewage treatment plant to completely treat their municipal sewage.

Bollaram Patancheru, Andhra Pradesh.

The Patancheru and Bollaram is one of the problem area identified in the Country to monitor the ground water quality. Seven stations in different villages were selected. The CPCB, South Zonal Office, Bangalore carried out the monitoring in the months of September, 2001, January, 2002 and October, 2002. The samples were analysed for 35 parameters by Andhra Pradesh Pollution Control Board Laboratory. The industries located at Bollaram-Patancheru area are falling into a broad category from leather and slaughter houses for manufacturing/formulating pesticides and bulk drugs. Treated/untreated effluent is being discharged out side the industrial premise. Lakadaram, Kistyareddy peta, Bollaram, Isakabavi were highly polluted area, Kardoor, Kardanoor, Inale, Bachupalli by stations were moderately polluted. In ground water samples TDS, Total Hardness, sulphate were high Heavy metals and Total Coliform and Faecal Coliform were present in some of the monitoring stations.

Cochin, Kerala.

The Cochin ground water quality monitoring was carried out by CPCB in the month of September, 2001, January, 2002 and May, 2002. The samples were analysed by Kerala Pollution Control Board Lab. In cochin organised sewage systems does not extend beyond the corporation limit. Most of the houses have individual soak pit and septic tanks. There are about 15 major industries in this area medium and small scale industries spread through out the study area. Most of ground water pH were acidic. This may be due to soil condition/industrial pollution. Heavy metals and fecal coliform. Total Coliform was found in most of the ground water. Pesticide, phosphate and cyanide were not traceable. Many of the monitoring points surrounded by the industries are reported to be unfit for drinking purpose.

Nagda & Ratlam (M.P.)

Ratlam is emerging as a big commercial and industrial city. A number of small and large industries, producing wide range of products, are located in the industrial area near the city. About 20 odd industries are also running in the Nagda including Grasim Industries. Three locations at Nagda and seven locations at Ratlam were selected for the evaluation of groundwater quality. The groundwater sources were handpumps, dugwells and tubewells and use of these groundwater sources are mostly for the domestic and irrigation purposes. Approximate depth of these wells varies from 20 feet from 400 feet.

Most of the samples were collected from the villages. Villagers consume groundwater as such for drinking, agriculture and cattle feeding purposes. Groundwater samples from the Ratlam areas was of dark brown colour in appearance particularly from the areas viz., Dosigaon, Bhatuni and Jadwasa may be because of leaching of industrial wastewater into the ground water stream. However, there is no surface flow of industrial wastewater in Dosigaon industrial nallah (drain). Water for drinking purpose in these areas is being supplied by District Administration. Pesticides were detected in some samples of Ratlam region, which may be due to industrial influences or/and agricultural activities. Estimation of certain heavy metals and physico-chemical parameters like TDS,. Sulphates, chlorides etc., may be due to industrial influences. Bacterial contamination in the groundwater may be due to anthropogenic activities. It is proposed to stop the use of groundwater particularly from Dosigaon, Ghatla, Bhajan kheda, Bhatuni and Jadwasa immediately and treated water should be supplied for human consumption and agricultural purposes in these areas.

Korba (Chhattisgarh)

Korba is an integral part of the Mahanadi river basin and is located over either the bank of river Hasdeo, also known as the powerhouse of Chhatisgarh State. The total population of the city is around 11.00 lakh. Due to the abundance of the natural resources, Korba area has been developed as an industrial centre. Total 3650 MW power is being generated from four numbers of power plants i.e. M/s. National Thermal Power Corporation, M/s. Chhattisgarh State Electricity Board (East) & (West) and M/s. Balco Captive Power Plant in this area. In addition to the power plant generation, aluminium metal is also being produced by M/s. Bharat Aluminium Company Ltd., at Korba. M/s. Indo Burma explosive plant is also being operated in this area where the nitrogen salt based explosives are being produced. Total 11 numbers of coal mines (open cast/underground) of SECL are also being operated in the area. Topography is undulating with elevation ranging from 9-332 meter above mean sea level. For the study of groundwater quality, the samples were collected during May, 2002, September, 2002 and January, 2003. The details of the sampling locations are presented in Table 5.21.

No changes observed in the groundwater quality with respect to pH and conductivity in compared to study made during 1994. Slight reduction in the mineral content i.e. chloride, calcium, magnesium, nitrate, chloride, sodium, potassium etc. recorded during the present study as compared to study made earlier. Pesticide content in the groundwater in the study area was also got reduced. Heavy metal content of all the tubewells/hand pumps are within the limit prescribed for drinking water quality except iron.

Reduction in bacteriological contamination in almost all the locations were observed. From the study, it was revealed that impact of industrial/urban activities is not affecting the groundwater quality. The groundwater quality has been improved as compared to earlier study. Groundwater Monitoring in Major Cities

Groundwater quality of three major cities in Uttar Pradesh (, Kanpur and Ghaziabad) and one city in Haryana (Faridabad - Ballabhgarh) is being monitored through a network of 38 representative locations. At each location, monitoring during pre- and post-monsoon phase is to be undertaken. The monitoring of post-monsoon phase at each location has been completed.

The conductivity, fluoride and chloride content at each location was higher. At one location in Ghaziabad, excessive colour has been found.

In all the cities, the total coliform count was high, and at some places faecal coliform was also present.

At all the locations, the iron content was high and chromium content was exceeding at 12 locations. In Kanpur, hexavalent chromium (a more harmful state) was recorded at one location.

Groundwater Quality in Metropolitan Cities

Assessment of groundwater quality in metropolitan cities of Lucknow, Ludhiana, Agra, Meerut, Faridabad and Jaipur is carried out to know the deterioration and identification of polluting sources.

It is observed that the increased abstraction has lowered the water table and increased the salinity (total dissolved solids), fluoride and lead levels in Agra and Faridabad region, whereas the quality in other cities found satisfactory with respect to major cations and anions.

Status of arsenic contamination in ground water of West Bengal

In the state of West Bengal, 9 out of total 18 districts are effected by arsenic. In the effected area, people are suffering from different arsenic related diseases. The inclined trend of human exposure to arsenic through ground water has become a major concern in West Bengal. Based on literature survey it may be mentioned that the area and population in nine arsenic effected districts, out of 18 districts in West Bengal are 38865 km 2 and 42.7 million respectively. Though all the people in this area are not exposed to arsenic contaminated water but most of them are at risk. Presently it is reported that 6 million people are exposed to unsafe level of arsenic contaminated water. Regular survey revealed more and more villages were being effected. It was also reported that water abstracted from 15-40m depth is most vulnerable. Arsenic contamination of ground water is attributed to leaching of arsenic from the rocky substrate in the deltaic belt of West Bengal. Over withdrawal of ground water through tube wells has aggravated the problem. One of the most important pre-requisite is to have reliable method to measure the arsenic in tubewell water. Number of arsenic field kits are being used for detection of arsenic. Performance of arsenic field kits was thoroughly studied in collaboration with School of Environmental Studies, Jadavpur University. The study revealed that most of field kits were not capable to generate reliable data. The rate of false detection was very significant and that caused lot of confusion not only among the decision makers but also among the local people (already published in American Chemical Society).

Considering the above fact, the study was undertaken to standardise the methodology for measurement of arsenic in ground water giving emphasis on quality control system to help the local people for analysis of tube well water and also to monitor the status of tube well water in arsenic effected area.

Based on recovery study using Standard Reference Material (SRM) traceable to NIST and inter- laboratory comparison, all the analytical factors were optimised to perform the analysis by hydride generation (VGA) – flame AAS. Facilities were also developed to analyse the sample by Ag-DDS method for cross checking. The laboratory has already established Good Laboratory Practice (GLP), protocols for sample preservation, storage, processing and analysis and quality assurance/quality control (QA/QC) measures.

Field survey was conducted to select arsenic effected area to collect the samples for characterisation of ground water. The results revealed that out of 189 tube well water samples collected randomly from various parts of four district ( 24, paragnas (S&N), Hooghly and Murshidabad ), 43 samples were above the permissible limit. The arsenic content in 60 sample were between 10 and 50 ug/l which were above WHO guidelines. The frequency of arsenic level and status are shown below in table 5.22. Though number of sample were very limited considering the number of tube wells in effected area but these result revealed that 54 percent tube well are effected at present. Also characterisation of ground water was done with respect to other parameters. Table 5.22 Status of Arsenic Contamination in Tube Wells Conc. Range (m g/l) Frequency Status < 10 86 Safe 10 – 50 60 Above WHO Guidelines > 50 43 Above WHO Guidelines Total 189

In 24 Parganas (S) the hardness of the ground water is significantly high and alkalinity is slightly high but dissolved solids were within permissible limit of drinking in most of the cases. The nitrate, phosphate, sulphate and chloride in ground water was within permissible limit.

In the Hugli, except hardness, dissolved solids (few cases) and calcium, almost all other parameters were within permissible limit. In Murshidabad, Ca and Total hardness in almost all the samples were significantly high. In 24 Parganas (N), Total hardness and sulphate were significantly high. Detail characterisation was made to evaluate the acceptability of water for domestic uses in terms of arsenic and other parameters and also to have idea to select the technology for arsenic removal.

Groundwater Quality Monitoring in Problem area Singrauli

Central Pollution Control Board, Zonal Office Kanpur carried-out monitoring of groundwater in Singrauli area through a network of six locations (Table 5.23). With reference to BIS- specifications (IS : 10500; 1991) for drinking water quality, groundwater quality status as observed in Singrauli area, during the current study is summarized below:

Physico-chemical and bacteriological parameters

Groundwater quality in the area has been generally observed to be alkaline and with moderate concentration of fluoride and colour. With regard to location specific status, the quality observed at Obra (Code : SG 1 ) has shown alkalinity, total hardness, boron and calcium exceeding the norms. Presence of total and faecal coliform has also been noted.

At Renukoot (Code : SG 2 ) high content of colour, alkalinity, TDS, and boron have been observed. At the other location in Renukoot (Code : SG 3 ) high content of fluoride, colour, total and faecal coliform have been observed. At Renusagar (Code SG 4 ) and at Anpara (SG 5 ) groundwater has high to very high content of fluoride (Fig 5.4). Moreover the high content of chloride, sulphate, nitrate and colour at Anpara has also been a significant observation. The presence of total and faecal coliform observed very high at Renusagar are however absent at Anpara. At Bina (Code : SG 6 ) apart from high colour content and coliform (total as well as faecal) the groundwater is of reasonably good quality.

Heavy Metals

Mercury and iron have been the only predominant metals in the area. While iron has been observed with high to very high concentration at almost all the locations with its highest concentration (10.2 mg/l) observed at Anpara (Code : SG 5 ), mercury too has been reported from all the locations except at Renukoot(Code SG2). Highest concentration of mercury ( 0.004 mg/l) has been reported from Renukoot(Code SG3) followed by Renusagar (code SG4), Bina (Code SG6), Obra (Code SG1) and Anpara (Code SG5). All the other heavy metals have been found to be within prescribed norms.

Pesticides

Lindane, DDT and aldrine have been the predominant pesticides observed. Among all, lindane has been reported at 4 out of 6 locations and its highest concentration (277 ng/l) is recorded at Renukoot (Code SG3), followed by Anpara (Code SG5), Renukoot (Code SG2) and Bina (Code SG6). DDT has been recorded at 2 locations viz.: Obra (SG1) and at Bina (SG6), the former location reported highest concentration of 216.2 ng/l. Aldrine was recorded only at Bina (Code : SG 6 ).

PRESENT STATE OF ENVIRONMENT, ENVIRONMENTAL PROBLEMS AND COUNTER MEASURES

1) STATE OF ENVIRONMENT

Bangalore

Bangalore is the principal administrative, cultural, commercial and industrial center of the state of Karnataka. Situated at an altitude of 920 meters above sea level, the city, which is spread over an area of 152 square kilometers, enjoys a pleasant and equable climate throughout the year. Its tree-lined streets and abundant greenery have led to it being called the 'Garden City' of India. However, since local entrepreneurs and the technology giant Texas Instruments discovered its potential as a high-tech city in the early 1980s, Bangalore has seen a major technology boom. It is now home to more than 250 high- tech companies, including homegrown giants like Wipro and Infosys. Consequently, Bangalore is now called the 'Silicon Valley' of India.

Bangalore, like many other cities in the country, has outgrown its infrastructure. It generates 2200 tonnes of garbage a day of which the Bangalore Mahanagar Palike (BMP) and the Bangalore Development Authority clear only approximately 60% garbage. Consequently, there is a huge backlog of un- cleared waste cluttering the city. The city has no official waste dumping sites and there is only one Government garbage treatment plant, which handles around 200 tonnes a day. In the absence of dumping sites, the garbage collected by the BMP and the private trucks get dumped along the highways, near the slums and the outskirts of the city. Bio-medical waste in Bangalore amounts to 0.5% of the total waste generated in the city everyday.

For comprehensive assessment of State of Environment, drain monitoring were carried out at various drains in Bangalore at peak flow time and lean flow time. Flow measurements were carried out and wastewater samples were drawn from the drain. The salient observations are: i) The high BOD & COD values in the drains indicate that the entire sewage does not lead to the existing sewage treatment plants, but significant fraction is discharged into three major storm water-carrying drains in three different directions. ii) The invariability in the flow values at Bytarayanapura drain during peak & lean time indicates that the catchments area for the storm water drain is quite large that smoothens the peak and lean flows.

Lote-Parshuram Industrial Area

The comprehensive pollution assessment exercise was carried out at Lote industrial area in Maharashtra State, including air & water quality, monitoring at source and also in ambient bodies (apart from monitoring noise levels). The study carried out at this estate (covering around 200 units engaged in production of various organic/inorganic chemicals), reveal presence of water pollution in river Vashishti, a major center for fish production. To treat the effluents generated by the industries recently the CETP has been provided. The air emissions were not due to the common air pollutants (SO 2 , NO x , CO, HC, Acid Mist etc). The levels of carbon monoxide were found within limits prescribed for industrial area. There is no common solid/hazardous waste disposal facility provided at the estate. The on-site storage facilities provided at the individual industries are not adequate, Lote Parshuram industrial estate needs concerted efforts by the concerned agencies for improvement in the environmental scenario. Diu

The Island of Diu has chaptered History, as it had been ruled by many kings and Dynasties, beginning with the Pauranic period and last being Portuguese from whom it was liberated along with Goa and Daman on 19 th December,1961. The Gazetteer states that the Diu history was started way back from Dwaparayug. Goa, Daman and Diu were in the possession of Portuguese which remained under their rule for nearly 450 years. They were liberated on 19 th December,1961 during operation Vijay and in the following year i.e. year 1962 they were constituted into a separate Union Territory admistered by a Lieutenant Governor and a popular Ministry. After Goa became a state, a Union Territory was formed on 30 th May, 1987, consisting of Daman and Diu.

Diu is a tiny island situated slightly off the coast of Kathiawar near the port of Veraval in Gujarat with a coastal length of 21 kms. and is located at a distance of about 768 kms. from Daman, the capital of the newly formed Union Territory of Daman and Diu. The island is bounded by Junagadh and Amreli Districts of Gujarat in the North and surrounded by the Arabian Sea from three other sides. The Diu island is connected by two bridges with the mainland and lies between North Longitude of 20 0 44'34” and 20 0 42'00 ” and East Longitude of 71 0 52'26”. The Diu town of located at the east end of the island.

The Diu island (Diu district) occupies an area of about 40 sq. kms, with maximum width of 4.6 kms from extreme North to South and 13.8 kms from East to West. The Island has one main town and 5 villages, which have one Municipal Council (B) type and two village Panchayats.

As per 2001 census the total population of the island is 44,110. The population is distributed in five villages namely Ghogla, Fudam, Simbore, Bucharwada, Vanakbara and Diu town. The main occupation in Diu is tourism, fishing, agriculture etc.

The industrialization in Diu was rather slow and started in 1971 with 17 unit and in 1981 it has increased to 103 industries, which have been further increased tremendously. Most of the industries are located in Malala and some are scattered in Bucharwada, Vanakbara etc. The type of industries located is Oil, Ice & Soda, Engineering, Distilleries, Salt manufacturers, floor & Rice mills etc. As reported by DPCC, Daman most of the industries in Diu were under shutdown due to the prevailing market downfall. Two rounds of detailed survey for Ambient Air quality, Traffic census, Noise pollution survey and ground water quality monitoring for the selected locations were carried out.

The ambient air quality was conducted at three locations (Vanakbara, Malala Industrial Estate, Central Bus Depot) for the parameters SO 2 , NOx, SPM, RSPM and Lead, and the results of the parameters ranged as: RSPM 31 µ g /m 3 to 159 µ g /m 3 , SPM 23.75 µ g /m 3 to 593.9 µ g /m 3 , NOX 7.6 µ g /m 3 to 24.8 µ g /m 3 , SO 2 all the time measured as below detection limit. Ground water samples were collected from different locations and analyzed for physico chemical parameters.

Tripura State

The study for preparation of status of Environment in Tripura has been carried out with aim to monitor environmental quality and updating the status report. Environment monitoring has been conducted with respect to air quality, water quality, bio-medical waste management, hazardous waste management at various part of Tripura.

Ground water samples were collected from 19 locations, distributed in four zones/district (North: 4, Dhalai:1, West: 11, and South: 3). Analyses have been carried out for physical characteristics, mineral constituent, toxic metals and organic pollutants. Analysis results indicate that TDS, TSS, chloride, Fluoride, sulfates are within permissible limits. Toxic heavy metals such as As, Pb, Cd and Cr have been found within permissible limit. No faecal coliform were found in any samples. Samples were collected from 12 points from 8 rivers namely, Howrah, Deo, Manu, Dhalai, Juri, Feni, Khowai and Muhri and from two lakes namely Amarsagar and Jagannathdihi. The water quality with respect to the parameters such as TDS, TSS , Chloride, Fluoride, Sulfate, Calcium, Magnesium, Sodium, Arsenic, Cadmium, Copper and Lead were found within permissible water quality limits. Total coliform, Fecal coliform were observed higher at all the locations. Oil and Grease was higher in Howrah river and in Chandrapur stream at Chandrapur because of automobile Garages in the area. Bacteriological quality of ponds with respect to total coliform and fecal coliform were observed unsuitable for drinking. The air quality monitoring have also been carried out at various locations. Table 6.1 presents number and capacity of major health establishments in Tripura. Considering specific waste generation factor, the quantity of bio-medical waste is estimated as 763 Kg/day. Presently, no appropriate system is available for treatment and disposal of bio-medical waste.

Leh & it's adjoining areas

Environmental status of Ladakh region was carried out. The areas surveyed was Leh town, the three brackish lakes and the Nubra Valley. This region has three major rivers namely River Indus, River Zanskar and River Shyok. The region is bereft of any natural vegetation and the greenery visible are due to the effort of the Forest Department. The study included the assessment of present status of air and water quality in the region, present status of Solid and Bio-Medical waste management in the region. Detail study of Leh area was done, as it is the only `urban pocket' in the Ladakh region and can be categorised as major source of pollution due to human activity. Semblance of water supply system is restricted only to Leh town which is catered exclusively by groundwater without any pre-treatment. High silt load in the surface water bodies is the major bottleneck for its utilisation as a source of water supply or any hydel power projects. The Notified Area Committee (NAC) under the Ladakh Autonomous Hill Development Council (LAHDC) supervises solid waste management. Use of polybags are banned, and refilling facility of mineral water bottles are common practice to reduce plastic waste. The entire Leh district has a formidable health care infrastructure. The health department is not aware of the Bio- Medical Waste Management Rules. Other salient observations of the study are as below:

• Water quality of community supply at Leh and tubewell in the Nubra Valley is suitable for human consumption except for very high total suspended load, more Iron and Manganese than BIS limits in river samples. • The sediment samples collected from the rivers (Indus and Shyok) indicated presence of heavy metals and high pH. · The three lakes monitored indicated very high dissolved solid (brackish nature) and their water was not suitable for human consumption. Tso Kar is the most brackish lake. • Presence of bacterial contamination (coliform) in most of the water samples can be attributed to grazing animals and outdoor defecation in the sparsely spaced out habitations. • The ambient air quality monitoring in the region with respect to sulphur dioxide and nitrogen dioxide were found within stipulated standards. • Solid waste of both municipal origin and biomedical wastes was being disposed to the common dump site without any treatment. The incinerator though installed for treating municipal wastes, not remain in regular operation. • S N M Hospital, the district Main Hospital, at Leh was being exposed to high sound levels as it is located on the national highway to Manali (Himachal Pradesh)

Digha

The Study has been undertaken for assessment of overall environmental status of Digha - presently an important coastal resort in West Bengal. Study included various aspects like geomorphology, land use, sewage and sanitation, waste management, economic activities, tourist facilities, quality of air, water etc. Beach Erosion is the tremendous threats to the physiography of Digha. Protective measures has been taken from Digha to new Digha by laying laterite boulders to reduce the pace of erosion. Cyclonic Storms frequency in this zone of Bay of Bengal is nearly four times higher than of Arabian Sea. Disaster management plan should be implemented more effectively for saving lives and resources in the region. Sewage system is still very much unorganised and open surface dispersal of waste in some area particularly at old Digha site poses risk to public health. Frequent failure of power supply results in usage of large number of DG sets causing noise and air pollution.

Suspended Particulate matter (SPM), Respirable Suspended Particulate Matter (RSPM), Oxides of Nitrogen (NOx) and Sulfur-dioxide (as SO 2 ), Lead and Polycyclic Aromatic Hydrocarbon (PAH) content of the air were monitored for 24 hrs. at four locations to assess the ambient air quality at Digha. The observed values are presented in Table 6.2.

Table 6.2 Ambient Air Quality At Digha

Water samples were collected at four sites (Fig 6.1) from the randomly dispersed wastewater stream. Dissolved oxygen was not observed at all sites, while pH varied between 6.5 to 7.5. Phosphate and nitrate values were observed between 0.01 to 1.3 mg/l and 0.05 to 0.15 mg/l respectively. COD, BOD, Ammonia, TKN and Coliform bacterial load have been found high. No sewage treatment plant is installed at Digha, which leads to release of untreated wastewater from the city area into the sea.

Fig 6.1 Wastewater Quality at Digha

Following initiative have been suggested for improvement of Environmental status of Digha based on the study:

• Development of Digha should be made as per MoEF Notification on Coastal Regulation Zone (CRZ), • Laying of drainage system and Installation of Sewage Treatment Plant. • Notification of the Municipal Solid waste disposal site beyond 500 m from HTL with proper fencing and soil cover. • Regulation of water abstraction from groundwater aquifers should be made to maintain subsurface water level. • Better traffic management and Road condition. • Adequate waste bins should be provided along the main road as well as sea guard wall with relevant captions. • Tourist Information Centre should be effectively established guiding tourists on `Do's' and 'Don'ts' along roadside and sea guard wall

Singrauli Central Pollution Control Board has undertaken studies on environmental quality in Singrauli area, with the help of Banwasi Sewa Asram, an active NGO in Singrauli area. The project has been focussed on generating trends in air and water quality data in the area and also to suggest area specific measures of pollution control. The findings of the study are as under:

AMBIENT AIR QUALITY

Sulphur dioxide (SO 2 )

At all the three impact monitoring stations viz. Beejpur, Murdhawa and Dala, an appreciable impact is observed with relatively higher concentration of sulphur dioxide ranging between 12-46 µg/m 3 at Beejpur, 7-48 µg/m 3 at Murdhawa and 5-31 µg/m 3 at Dala but confirm to prescribed standard (Fig 6.2). Sulphur dioxide and NOx concentration were found increasing in evening time at Beejpur while in night at Murdhawa and Dala.

Nitrogen Oxide (NOx)

It has followed similar trend analogous to sulphur dioxide. The range of concentration recorded at different locations were 12-76 µ g/m 3 at Beejpur, 15-54 µ g/m 3 at Murdhawa and 14-48 µ g/m 3 at Dala. All the time concentration recorded, have conformed to prescribed standard (Fig 6.2).

Suspended Particulate Matter (SPM)

Suspended Particulate Matter was highest at Dala 169-2757 µ g/m 3 . It has shown significantly high concentration at all the three impact stations, particularly at Dala it has always exceeded the prescribed standard, while at Beejpur and Murdhawa it exceeded in 50% and 72% observations. The range recorded at Beejpur & Murdhawa has been 99-358 µ g/m 3 and 148-684 µ g/m 3 respectively. The concentration of SPM increased during night at Beejpur, whereas during evening & morning time at Murdhawa and Dala respectively.

Fig 6.2 Ambient Air Quality with respect to SO 2 /NOx at Singrauli

Respirable Suspended Particulate Matter (RSPM)

The status of RSPM has been more or less analogous to SPM, while its highest concentration (95-660 µ g/m 3 ) has been recorded at Dala, where it exceeded the standards in 94% observations. In Beejpur and Murdhawa, the range of concentration has been 48-115 µ g/m 3 and 73-213 µ g/m 3 respectively. Moreover, it has exceeded in 38% and 45% observations at Beejpur and Murdhawa respectively. The concentration increased during evening at Beejpur & Murdhawa, whereas at Dala higher concentration were generally recorded during morning or night hours.

RSPM –SPM ratio : As regard ratio of RSPM and SPM, it is observed that at Baseline station (Kewal) RSPM values were 52% of SPM, whereas the percentage gradually decreased in the order Beejpur (43%)> Murdhawa (35%) > Dala (31%) (Fig 6.3).

Fluoride

The status of fluoride was recorded at two locations viz. Murdhawa and Beejpur, where appreciable concentration was recorded. The concentration at Murdhawa was comparatively higher (max. 8 µ g/m 3 ) than Beejpur (max. concentration 3.3 µ g/m 3 ). Higher concentration of fluoride were recorded at Murdhawa during evening and night time (Fig 6.4).

Fig 6.3 Ambient air quality with respect to SPM/RSPM

Fig 6.4 Ambient air quality with respect to Fluoride

M ercury

The status of mercury has been quite high with exceptionally high concentration recorded at all the three locations. While highest concentration 1959 ng/m 3 recorded at Dala the concentration range of 1.34- 190 ng/m 3 at Murdhawa and 1.24-1592 n g/m 3 at Beejpur have not been of any reprieve either.

Physico-Chemical Status of Surface Water

Drains The monitoring was concentrated for assessment of water quality in three drains viz: Murdhawa drain, Dongia drain and Ballia drain.

A serious anomaly of high fluoride (7.2 – 55 mg/l), high COD (max 1326 mg/l), high TSS (max 2500 mg/l) and occasional alkaline pH. Exceptionally high mercury (50-180 µ g/l), moderate concentration of COD (288-700 mg/l) and general absence of dissolved oxygen have been observed at Dongia drain. Ballia drain too has reported high concentration of mercury (max 2.4 µ g/l), fluoride (max 1.8 mg/l) and occasionally high COD (629 mg/l) and very low dissolved oxygen (2 mg/l)

River Rihand

Before confluence with the reservoir, the river has reported reasonably good water quality, except for marginally higher concentration of fluoride (1.2 mg/l). However in the course of the river downstream of the Rihand Dam and especially after the confluence of Murdhawa drain, there has been marginal increase in fluoride concentration (1.8 mg/l), which further increases to 2.0 mg/l, after the confluence of ash pond overflow from Obra, where high concentration of mercury (2.6 µ g/l) has been reported.

Rihand reservoir

A significant observation has been an increasing anomaly of fluoride (1.2 to 1.8 mg/l) observed in the reservoir after the successive confluence of Balia drain, Dongia drain and Murdhawa drain respectively. There has been an occasional drop in dissolved oxygen concentration (4.8 mg/l) after the confluence of Ballia drain. High concentration of mercury has been particularly observed after confluence of Ballia drain and Dongia drain.

Surface Impoundments (Bawadis)

High concentration of fluoride (2.8 to 5.6 mg/l) has been a significant observation in all the five Bawadis monitored, with maximum concentration reported in Bawadi at village Chetwa. The Bawadi at Govindpur has been of particular significance on account of high conductivity (720-1210 mg/l), high TDS (658-687 mg/l) and an occasional drop in dissolved oxygen (4.8 mg/l). High concentration of mercury (3.1 µ g/l) has been observed in Bawadi at village Bakulia.

Western Coal Fields (Madhya Pradesh)

The Western Coalfields contributes about 11% of the national coal production (35 mt/yr). It has mining operation spread over the states of Maharashtra (in Nagpur, Chandrapur & Yeotmal Districts) and Madhya Pradesh (in Betul and Chhindawara Districts). The coal mining operations in M.P. are done in three agglomerations – Pench, Kanhan and Pathakhera Areas. Most of the mines are located under- ground, except a few in Pench and Kanhan areas. These mining operations result into new mine water discharge points, dust generating sources and transportation. The coal transportation is both, by road and rail.

The ambient air quality in some of the residential areas and some of the villages located on the transportation networks can be improved by improvement in traffic management and popularizing the use of LPG. Extensive tree plantation will help in protecting the residential areas from high air pollution and also the noise.

ENVIRONMENTAL RESEARCH Research and development activities play an important role in assessment and control of pollution. The important research activities carried out during the year 2001-2002 in various fields like air and water, pollution related research studies, municipal solid waste related research studies, standardization of analytical techniques, analytical quality control (AQC), laboratory development, industries specific research studies are summarized below.

In the RAC meeting CPCB's Scientists & Engineers made presentations about the on-going R & D activities and new projects proposed to be taken up on thrust areas. It was also proposed during the meeting that CPCB should undertake Memorandum of Understanding (MoU) with Department of Science & Technology, New Delhi to carry out R & D activities in the field of pollution abatement and control.

DEVELOPMENT OF TOXICITY BASED STANDARDS FOR INDUSTRIAL EFFLUENTS

The regulation of quality of industrial effluent is utmost necessary in order to protect the environment from adverse effect caused by effluent discharge. The toxicity test is summary parameter, which provides information about other effects parameters. The use of summary parameters like toxicity test is gaining importance for regulatory purpose as it has many more advantages over physico-chemical parameters. Realizing the importance of toxicity parameters and for the development of toxicity based Minimum National Standards (MINAS), a collaborative project being undertaken by Central Pollution Control Board involving five laboratories viz. Gujarat Pollution Control Board, Gandhinagar; National Institute of Occupational Health, Ahmedabad; National Environmental Engineering Research Institute, Nagpur and two laboratories of CPCB located at Kanpur and Delhi.

The treated and untreated wastewater samples were collected jointly alongwith all five participating laboratories from effluent treatment plants and combined effluent treatment plants of selected Pulp & Paper industries and Tanneries. The collected samples were analyzed for estimation of toxicity independently by the laboratories adopting the BIS approved method based on Dimensionless toxicity factor (TF). The Toxicity Factor (TF) is the minimum dilution required for the hundred percent survivals of test fish for a period of 48 hours.

The analytical results of pulp and paper industries effluent indicate that the toxicity factor (TF) in the untreated effluent ranged between 1 to 16 whereas in treated effluent, its value ranged between 1 to 4. The range of percent toxicity reduction after treatment varied from 0 to 100%. In few cases, increase in the level of toxicity after treatment was also observed.

STANDARDIZATION OF METHODOLOGY FOR MEASUREMENT OF CERTAIN HAZARDOUS ORGANIC COMPOUNDS (POLYCHLORINATED BIPHENYL)

PCB's are the group of highly toxic, synthetic, chlorinated organics compounds, with chlorine substitution around biphenyl group as basic structural unit and constitute 209 individual congeners. The PCB species are non- biodegradable, stable with high toxicity and having tendency for bioaccumulation. It is believed that PCB's do not occur naturally and they are resistant to chemical and biochemical process. The PCB's have received much attention in recent years as ubiquitous environmental contaminants and their overwhelming problem of continuing environmental impact.

The PCB's have potential industrial applications where non-flammability and heat resistant properties are desired and these compounds are more commonly used in heat transfer system, hydraulics/lubricants, transformers, capacitors as plasticizer and as petroleum additives. The PCB congeners, which contain fewer chlorine substitutions in ortho position, are more toxic than those having more chlorine in other portions. The most toxic PCB's are tetra, penta and hexachlorobiphenyl congeners that are un-substituted in the other position.

The analysis of PCB in environmental sample is quite complex as numerous congeners are available in form of complex mixtures; because of this there are only few laboratories, which could analyze PCB's in environmental samples.

The laboratory of Central/State Pollution Control Board and other environmental laboratories have limited technical expertise about measurements of residual PCB's in environmental matrices viz. waste waters, industrial effluents, sludge and soil. The project standardization of Methodology for measurement of certain hazardous organic compounds has therefore been undertaken with following objectives.

• To develop facilities and Standardization of analysis of PCB's in water, soil and sediments. • To standardize procedure for extraction, clean up, concentration and pre-treatment of sample. • To standardize GC optimum conditions (oven temp. detector, injector flow etc.) to achieve resolved peaks of individual PCB species. • To undertake spiking and recovery studies in the field samples.

The PCB's congeners in Aroclor Standard Solutions have been analyzed at CPCB Laboratories by Gas Chromatograph with Electron Capture Detector (ECD). Peak profiles of six Aroclor mixtures and overlapping peak were observed with GC-ECD. Some least overlapping peaks of Aroclor 1221, 1016, 1254 and 1260 were selected, which were used for calibration of the instrument. Qualitative analysis of Aroclor mixtures was also performed with GC-MS and the observations were compared with the literature. Congener identifications were predicted with the help of mass spectra and findings of other research data. Retention times and mass spectra of 28 individual congeners of toxicological significance were observed. Five levels of calibration (range 10 to 100 pg/µl) were performed using dilutions of mixture containing 28 PCB's congeners.

To estimate PCB's level in field samples, water and sludge samples were collected from river Yamuna at five locations in Delhi stretch and five major drains merging into river Yamuna in Delhi. Water samples were extracted after filtration with methylene chloride. Suspended solids of aqueous samples and sludge samples were extracted with hexane – acetone mixture. Extracts were concentrated using rotary vacuum evaporative concentrator and exchanged to Cyclohexane. Concentrated extracts were subjected to acid/base/silver nitrate clean up and basic alumina clean up, concentrated by nitrogen blowing and being analyzed on GC-MS using congener-specific method of analysis.

DEVELOPMENT AND STANDARDIZATION OF TRIHALOMETHANES (THM'S) IN ENVIRONMENTAL SAMPLES

The halomethanes include all one carbon compounds with substituted chlorine or bromine. The sources of these compounds are industrial discharges and the synthesis during disinfection with chlorine. Trihalomethanes (THM's) occur in drinking water principally as a product of reaction of chlorine with naturally occurring material and bromide that may also be present. With respect to drinking water contamination, four members of THM's viz. chloroform, dichlorobromomethane, dibromochloromethane and bromoform are important. World Health Organisation (WHO, 1993) has already enacted the health related guidelines values in drinking water.

In order to standardization of measurement methodology and regularly monitor the presence of these compounds in drinking water, the infrastructure facilities are under development at CPCB Laboratories.

STANDARDIZATION OF METHODOLOGY FOR PAH COMPOUNDS AND MEASUREMENT OF PAH IN KOLKATA.

Poly-cyclic aromatic hydrocarbons (PAH) are important organic aerosol components generated from a variety of combustion processes and emitted into the atmosphere preferentially associated with the sub micron size particles. Some species of PAH are known human carcinogens. As a result it has received a good deal of attention over the last thirty years. It is well known that ambient air in Kolkata is more polluted than many other major cities. Therefore it was considered necessary to standardise the methodology for measurement of 6 PAH species initially and to generate data for PAH in ambient air of historical places namely Dakshineswar, Belur and Victoria memorial. The details of target compounds are shown in Table 7.1.

Table 7.1 Target PAH Compounds of Interest

The uncertainty contributions in standard preparation of PAH species were quantified. The contributions from purity and volume were negligible and therefore not being considered. Before using the GC for analysis, instrument was calibrated by observing the peak area (y) to different level of PAH species (x). The linear least square equation was used to obtain the slope and intercept for calculating the concentration of sample against peak area. Most significant source of uncertainty i.e. random variation in y were considered to measure the level of uncertainty. The calibration results along with slope, intercept and detection limits are presented in the Table 7.2.

Recovery Study: Two sets of five filters (blank) were spiked with known quantities of six target compounds. They were processed as done for sample and the results are shown in Table 7.3. The average recovery figures for the individual species were inadvertently used higher than the quantity available in the field samples. However, in this level, percentage of recovery was varying from 91 to 137. With respect to the nature of PAH compounds, this recovery is satisfactory and acceptable.

Sampling : EPM 2000 filter was used to collect particulate phase. The samples were collected over 24 hours with quantification of volume using high volume sampler maintained very carefully. Sampler was leak checked before each sampling event. Sample data sheet filled in with all details along with filter paper brought to lab and kept in dessicator in a freezer until extraction.

Extraction : The sample was extracted following USEPA method with some modification according to our scope. The final purified extract is analysed under the following operating condition :

Instrument - Chemito GC – 1000

Injection - 0.5 ml

Oven temperature - Initial temperature 140°C holding for 1 min. increased at the rate of 8°C/m to 205°C, increased at the rate of 25°C to 255°C holding for 20 min. Total run time - 32 min.

Carrier gas - Nitrogen linear flow 30 ml/min

Gases for FID - Hydrogen with 30 ml/min and air about 300 ml/min

Column - BP 0.5 – 5% phenyl polysiloxane

Calibration - Calibration is performed using a standard PAH mixture containing six compounds.

Standard addition method : The sample filters fortified with SRM were processed to evaluate matrix influence on the recovery of target PAH compounds in this test method. Few filter sample collected in duplicate adjacent to sampling site were used for recovery study. That filter were cut into two : one part was placed in one soxhlet and another part in another soxhlet spiked with certified standard. The sample filter is folded in four and placed at the bottom of large clean soxhlet body. Then extraction was done following USEPA method. The result of standard addition method are shown in the Table 7.4. Revealed that percentage of difference from expected values were from 4 to 35, this may be considered satisfaction and acceptable. Based on this performance measurements in ambient air were done.

DEVELOPMENT AND STANDARDIZATION OF SOIL AND SOLID WASTE ANALYSIS FOR ANALYTICAL QUALITY CONTROL (AQC)

Municipal Solid wastes (Management and Handling) Rules, 2000 and The Hazardous waste (Management and Handling) Rules, 2000 (Amendment) notified under Environment (protection) Act, 1986 requires analysis and characterization of the solid wastes. As on date many laboratories of pollution control boards are not fully equipped for carrying out the analysis of such wastes. Keeping this in fact, the project is proposed to standardize the analysis of soil (polluted) and solid waste with a focus on conducting AQC exercises to the laboratories of SPCB/PCC and also laboratories recognized under E(P) Act. In this study, different polluted soil, industrial solid waste, Hazardous wastes, Municipal Solid Waste (MSW) etc. have been collected, hamozinised and analyzed for various physico chemical parameters. Two sets of homogenized MSW compost samples were distributed among 75 laboratories of Pollution Control Boards and committees for carrying out analysis under the Inter laboratory AQC programe. The parameters covered are pH, conductivity, water-soluble solids, loss on ignition, IKN, Total P2O5 and Total K. In phased manner, other solid waste samples of Hazardous wastes, polluted soils etc. will be carried out.

IMPACT OF ENVIRONMENTAL POLLUTION CREATED BY UNORGANIZED SECTORS IN KANPUR CITY

Kanpur is one of the largest agglomerations of north India. Some times Kanpur once known as Manchester of India is now showing its decreased growth in industrial sector. Despite these facts, the tremendous increase in population of the city has created multiple demands of the citizens that are being met by the local market. The various activities/small manufacturing/processing units are scattered all over the city and in most of the cases the government agencies have no control over them. These activities are being performed by non-scientific personnel and hardly have any environmental consideration. So far no effort has been made to control these kind of problems. This has not only resulted in serious environmental problems but also shadowing the different developmental activities being under taken in the city by government and non-government agencies.

In view of the above an effort has been made to have an over view of unorganized sectors in the city. Inventory of all-important sectors have been done. Inventory of approximately 4000 units covering the following sectors have been done in the first phase of study;

• Dairy (Chatta) • Bullion refinery • Small potteries • Sweet mart • Bakery • Service Stations

Salient features of each sector may be summarized as below

Dairy

Ø The units are scattered all over the city.

Ø The flock of cattle may also be seen as a mobile dairy unit moving in the city. This activity not only affects the aesthetic view of the city but also prone to accident.

Ø The wastewater generated mainly by floor washing contains high BOD, COD and TSS and goes directly to the city sewer/open drain without any treatment.

Bullion Refinery

Ø The units are concentrated to certain localities of the city.

Ø Create lot of air pollution in terms of acid fumes.

Ø Also discharges highly acidic wastewater to the municipal sewer/open drain without any treatment.

Small Potteries

Ø The units are scattered all over the city.

Ø Creates severe air pollution due to partial burning of fuel wood, cow dung cake and coal.

Ø The problem is more prominent during winter season.

Sweet mart

Ø Scattered all over the city.

Ø Creates severe air pollution due to burning of hard coke, HSD and kerosene.

Ø The problem is more severe during morning time.

Ø Also contribute high BOD and COD to the municipal sewer/open drain through wastewater generated mainly by washing of utensils.

Bakery

Ø The units are concentrated to certain areas of the city.

Ø Creates air pollution due to burning of fuel wood and hard coke.

Service Station Ø Scattered all over the city.

Ø Use huge amount of fresh water for washing of vehicles.

Ø Create water pollution in terms of high TSS and Oil & Grease.

Ø Wastewater discharge is without treatment to the municipal sewer/open drain.

The data collected during studies shall be used in interpretation of the problems created by the specific sector and for probable control strategies.

COMPARATIVE STUDIES ON METHODOLOGY OF ANALYSIS AND CHARACTERIZATION OF HAZARDOUS WASTE

Hazardous waste can be defined as "Chemical or biological refuse of industrial or consumer origin, considered potentially dangerous to human and/or the environment. As per Schdule-4 of Hazardous Waste (Management & Handling) Rules, procedures for characterization of Hazardous waste has to be recommended.

Many test procedures of Corrosivity, Reactivity, Ignitability, Toxicity are available for characterization of Hazardous Waste substances. One such test procedure is the Toxicity Characterization Leaching Procedure (TCLP). As per US-EPA method, the solid waste is leached using two levels of pH buffers i.e. 4.93 + 0.2 and 2.88 + 0.2 depending upon the chemical nature of samples. TCLP followed in USA and Canada is different in terms of procedure and standards whereas in Europe, they do not include TCLP as part of regulation on hazardous waste Management. Other method popularly followed in European counties is Constant pH (pH Stat: say 4.0) Extraction method. Some countries follow using distilled water extraction procedure. The composition and levels of leaching substances vary from method to method and thereby the interpretation with reference to standard limits also varies considerably. Though no method could able to match with real field situation, a judicial approach has to be made to derive better choice of method.

Keeping these facts in view, the project study has been formulated to carryout a comparative studies on various leachate test procedures using wastes generated from different units like Tannery, Lead & Zinc recovery (Lead & zinc slag/slag ash), Pesticides, Basic drugs, Dyes & Dye- intermediates and land fill sites for deriving better choice of method in the light of the Hazardous Waste Management and Handling Rules, 2000 (Amended). The main objectives of the study are:

• to assess the merits and demerits of various leaching procedures. • to estimate variations in the levels of leaching under various test methods. • to suggest a suitable test procedure for toxicity characterization to be followed uniformly in India.

During the study, solid waste sample from Tannery unit has been collected, homogenized, extracted under various extraction procedures like US-EPA - TCLP, European Constant pH and Distilled Water Extraction and analysed for metals. In addition, the Total metal contents of the sample were also analyzed for comparison purpose. The general characteristic of the waste in terms of pH, Conductivity, Total water soluble Solids, Loss on Ignition (%) and Organic Carbon.

The general characteristics of the tannery solid waste( Hazardous waste) is presented in Table 7.5.

Table 7.5 General characteristics of the Tannery solid waste( Hazardous waste) S.No Parameter Value 1 pH 7.99 2 Conductivity ms/cm 3970 3 Total water soluble Solids (%) 1.6 4 Loss on Ignition(%) 35.73 5 Organic Carbon(%) 4.27

The leachate concentrations of various metal under different Extarction procedures are presented in Table 7.6.

Table 7.6 Leachability efficiency of various extraction procedures for different metals (mg/Kg) from Hazardous waste of Tannery unit

Maximum extraction was found in pH Stat method for metals like Chromium, Copper, Iron, Nickel, lead and Zinc (Table 7.6) when compared to other methods (water Extact, TCLP). Chromium, being the predominant metal present in tannery waste, leaches to be maximum of 134 mg/Kg under pH Stat method as compared to lower extraction found in TCLP (5.30 mg/Kg) and Water Extraction (6.20 mg/Kg) methods. From the results obtained for different parameters following the Water extract, TCLP and pH Stat extraction, it is determined that in overall pH Stat is leaching out maximum followed by TCLP and the water extract. Further studies using other types of Hazardous wastes are in progress.

STUDIES ON THE EFFECT OF HIGH DISSOLVED SOLIDS ON THE RATE OF BIO-DEGRADATION OF WASTES

Biochemical Oxygen Demand (BOD) is a good indicator of measuring organic load. The rate of biodegradation in natural environment is affected by many factors such pH, temperature, dissolved oxygen, microbial bacteria, dissolved solids etc. Much study is not carried out on the impact of dissolved solids on the rate of degradation of wastes particularly in India. Keeping these in fact, a study on the “Effect of high dissolved solids on the rate of bio- degradation of waste water” was carried out at Central Pollution Control Board, Delhi. The main objective of this study is to find out the effect of high dissolved solids on the rate biodegradation of organic matter

Samples collected from Sewage Treatment Plant, Gurgaon, (Inlet and Outlet), Distillery Industry (Inlet) and Common Effluent Treatment Plant Mangolpuri (Inlet) were analysed. One synthetic sample of GGA (Glucose Glutamic Acid) was also used as a control. The total dissolved solids (TDS) content in the incubated BOD bottle was set ranging from Samples were kept for BOD test in such a way that final concentration of TDS in the BOD bottles were in the range of 500, 1000, 2000, 3000, 4000, 5000, and 6000 mg/l for each sample. For raising TDS levels, a natural ground water sample having TDS of 6002 mg/l has been used as dilution water.

It has been observed that Synthetic sample of GGA (Glucose Glutamic Acid) showed % reduction on the rates of BOD degradation as 5, 9, 19, 24, 30, 38, and 48 % respectively under different levels of TDS mg/l. Similarly the comparative values of the % reduction of the rates of BOD under different TDS levels for various types of samples are presented in Table 7.7. It is observed that overall mean percentage (%) of BOD degradation rates were 5, 9, 16, 20, 25, 31 and 39 % respectively under 500, 1000, 2000, 3000, 4000, 5000, and 6000 mg/l of TDS levels respectively

Table 7.7 Comparative values of the % reduction of the rates of BOD under different TDS levels for various types of samples BOD % Reduction Condition Used for TDS mg/l GGA Industrial STP (In) STP (Out) CETP Mean S.D. level 500 5 6 2 6 8 5 2.08 1000 9 11 3 12 13 9 3.89 2000 19 19 6 20 15 16 5.80 3000 24 24 9 24 21 20 6.50 4000 30 28 11 28 30 25 8.10 5000 38 36 13 33 36 31 10.30 6000 48 43 17 43 43 39 12.40

Note: BOD - Biochemical oxygen demand STP (Inlet) - Sewage Treatment Plant (Inlet) TDS - Total dissolved solids STP (Outlet)- Sewage Treatment Plant (Outlet) GGA - Glucose Glutamic Acid CETP -Common Effluent Treatment Plant Industrial - Distillery Industry

It may be inferred that the rate of biodegradation of organic waste is inversely proportional to the concentration of inorganic dissolved solids present in the aquatic medium.

The observation reveals that the high TDS levels in water bodies decrease the rate of biodegradation considerably. Further this study emphasizes the need of the control of TDS levels through fixation of standards for aquatic system to improve the rate of degradation of organic waste.

IMPACT OF WORSHIP IDOL IMMERSION

Idol immersion in river Yamuna in Delhi

The idol immersion in water bodies is the social ritual followed immediately after the Dushehra celebrations. The well decorated Clay/Plaster of Paris idols are worshipped during Durga Puja celebration at various venues. At the end of celebrations, the idols are taken into processions to various ghats of River Yamuna for immersion in river water.

The impact of immersion of worship idols in Yamuna River after Dushehra festival has been studied by Central Pollution Control Board at Delhi stretch from upstream Wazirabad to downstream Okhla barrage. It was estimated that approx. 1600 idols were immersed at Ramghat, ISBT and Okhla in Delhi stretch of River Yamuna during Dushehra Festive Season 2002. It has been derived from this study that various items used in preparation of idols have impact on aquatic environment during immersion (Table 7.8).

Table 7.8 Impact of Various Items on Aquatic Environment during Immersion of Idols S. Items contributed by Impact on Aquatic Environment No. idols immersion 1. Clay/Plaster of Paris Increase dissolved solids, suspended solids in water, contribute metals, sludge 2. Decoration material viz. Contributes suspended matter, trace metals (Zinc, clothes, polish, paint, lead, iron, chromium, arsenic, mercury etc.) ornaments cosmetic metalloids and various organic and inorganic matter, items etc. oil & grease etc. 3. Flowers, Garlands, oily Increase floating suspended matter organic substance contamination, oil & grease and various organic and inorganic matter 4. Bamboo sticks, Beauty Big pieces got collected and recycled while small articles pieces remain floating in water or settled at the river bottom inhabiting river flow 5. Polythene bags/plastic Contribute suspended, Settleable matter and items hazardous material to water and chokes the aquatic life 6. Eatables, food items Contributes oil and grease, organics to water bodies. etc.

The impact on water quality of river have been observed with respect to levels of conductivity, Total and Dissolved solids. Biochemical oxygen demand. River bed sludge analysis reflected elevated levels of trace metals viz. iron, arsenic and mercury. Based on the study, the following suggestions have been made to reduce the pollution load from idols immersion activities:

• Areas may be earmarked for immersion and other related activities to prevent indiscriminate disposal and to help retrieval of recoverable materials. • Temporary confined pond near rive locations may be identified for immersion of idols and other worship material to prevent pollution of main river stream. The closed pond water may be disposed into Main River after settling, scavenging and treatment. • The offerings like flowers and leaves may be collected in separate containers or in pits for composting. • After immersion, the recyclable articles like Jari, Clothes, plastics, aluminium foil, wood and bamboo may be taken out from the water bodies. The civic authorities may engage agencies/persons for doing the job. • Environment friendly practices such as use of biodegradable dyes and paints may be encouraged. • Public should be made aware of adverse affects of idol immersion in river water. • Rag picker activities through which recyclable material is removed should be encouraged further to avoid the contamination of river water with floating materials like plastics, flowers, wooden structure etc.

Idol immersion in Ponds in Kolkata

The number of pujas are held preparing idols, which are ultimately immersed in water bodies as a part of religious and cultural event. The major one is Durga Puja in Kolkata, when big idols in large number are prepared using different types of materials such as clay, straw, woods, dyes etc. During immersion these are disposed off in the water body. In addition to these, disposal of fruits, flowers and other materials may cause deterioration of water quality. Keeping this in view, a study was undertaken in Kolkata to assess the changes of water quality due to immersion of idol. Dry study was also carried out to quantify the raw materials required for making the idol to have a stoichiometric quantity being disposed. The varnish oil and water soluble dyes are considered the source of pollutants among the raw materials used in preparation of idol. For impact study, three ponds were selected for sampling Salient features of these ponds are presented in Table 7.9. Sampling of water and sediment was done before and after immersion at different four points of each pond – two at immersion site and two at offsite to represent the whole water body. But the coefficient of variation of results of four points (not tabulated here) showed wide variation indicating non uniform distribution of major mearurand in pond. In this condition it would not be very reliable to compare water quality during pre-immersion and post immersion in such large ponds. However, to have an idea about charges before and after immersion, the values of four point in each pond have overall changes of different variables are depicted in Table 7.10. The results revealed that no major changes with respect to Chloride, Potassium, Sulphate, Phosphate, Calcium. Though very little inclination of these variables were observed. Considering the volume of water in three ponds quantity of metal increased due to immersion was quantified. From the results (Table 7.11) it may be mentioned that 6.4 Kg. of iron, 0.32 Kg. Zinc and 1.02 Kg Manganese were added to the pond through immersion. Though there may be error in quantification of metal load due to wide variation among different points of the pond and lack of normalisation of metal with respect to TSS, pH, sediment load, density of plankton etc. But clear inclined trend through not exactly quantified was observed in this study. The above findings were based on one time information. Therefore, the changes due to immersion of idol required to be confirmed through further study.

STUDY OF FISH MORTALITY IN RIVER YAMUNA

Fish mortality occurred on a massive scale in river Yamuna initially at Agra stretch on 13 June 2002 and later at nearby Bah (80 Km D/S) on two closely followed occasions within a fortnight. The CPCB submitted its findings that basically ruled out any toxic contamination (later confirmed by official reports) and held Dissolved Oxygen depletion in the night time to be a prime cause for the mishap (Tables 7.12 & 7.13).

The diurnal variation of dissolved oxygen accompanied with low flow rate might have aggravated the situation in critical periods (lean). The study suggested for regular DO monitoring to see the diurnal variation over seasons and emphasized to ascertain minimum flow rate in the river for normal upkeep of the river ecosystem.

EFFICIENCY TESTING OF AUTOCLAVES USED FOR HOSPITAL WASTE TREATMENT BY SPORE TESTING METHODOLOY

The Biomedical Waste (Management & Handling) Rules, 1998 notified by Govt. of India, has stipulated rules for proper collection, storage, transportation, treatment and disposal of bio-medical waste. As per Bio-medical Waste Rules, 1998 the hospitals have to install treatment facilities like incinerators, autoclaves, etc. for treatment of bio- medical wastes generated to ensure safe treatment & disposal of infectious hospital waste. These treatment facilities should operate at designed efficiency level.

A project has been continued by Central Pollution Control Board for assessment of treatment efficiency of autoclaves used during hospital waste treatment based on standardized spore testing methodology. The objectives of the study was in-situ assessment of the efficiency of autoclaves and hydroclaves installed at various hospitals to ascertain 4Log10 reduction of Bacillus stereothermophilus biological indicator.

The standardized spore testing methodology using Bacillus Stereothermophilus as biological indicator has been used with a view for its application for efficiency testing of autoclaves and hydroclaves installed at Delhi and Kanpur. The results obtained during the study indicated that the Bio-medical waste treatment autoclaves installed at various hospitals are satisfactory with respect to sterilization of bio-medical waste undertaken at these autoclaves.

GEOACCUMULATION AND BIOACCUMULATION STUDIES

Geo-accumulation and Bioaccumulation of Heavy Metals and Pesticides on Soil and Crop Vegetation during Wastewater Irrigation

With increasing paucity of fresh water untreated/partially treated sewage water is increasingly utilized for irrigation of soil and growing of crops. The sewage wastewater generation from urban areas has been constantly increasing, while the wastewater treatment capacity is quite less than the total wastewater generation. The treated/untreated wastewater is increasingly utilized for irrigation of crops, vegetation etc. With the view to study the impact of wastewater on geo-accumulation and bio-accumulation on irrigated soil and crop vegetation in Delhi, the project studies have been undertaken. The study undertaken between April, 2002 to March, 2003 included following aspects:

• The survey has been conducted at Najafgarh drain basin and dry cultivated areas in river bed of Yamuna after confluence of various drains, where sewage water is being used for irrigation of soil and growing crops vegetation. • Water, soil, plants and vegetables such as Brinjal, Spinach, Bitter gourd, Lady's finger etc. have been collected and analyzed for trace metals and pesticides during consecutive random sampling rounds.

From the analytical data, it has been derived that sewage irrigated soil have elevated metallic content, which may be the cause of transfer of metals from soil to plant tissues, which may bio-accumulate in edible parts of vegetables.

Assessment of Bio-accumulation of Heavy Metals in Fish

Accumulation of certain toxic metals in different sea food and their subsequent transfer to man through the food chain is a great concern and number of incidents of heavy metals contamination in fish and resultant human suffer have been reported time to time all over the world. With the Increasing rate of metal pollution in river, ponds and sea, there is possibility of contamination of metals in fishes. Fish musculature is a major path through which heavy metals can enter the human body. Keeping this in view, monitoring was carried out to ascertain the level of metal content in edible fish tissue collected from the coasts of West Bengal. Fishes irrespective of size and age were collected from two fish landing stations (Digha and Diamond harbour) for the analysis of heavy metals. The concentrations of metals observed in muscle tissue of different species of fish are presented in Table 7.14. The estimated concentration of all metals in fish muscle compared well with those of reported values in fishes from different parts of other coasts.

* Species Not Available

As reported fish actively regulates zinc in their muscle tissue but prevailing concentration of zinc in fish tissue particularly in Diamond Harbour as shown in Table 7.14 indicated the incomplete regulation of this element. Iron was found most abundant in all the species. Prevailing concentration of different metals in fish tissue and variation in same species and variation from species to species and correlation coefficient among different metals would help to concentrations of metals in fish tissue may be attributed to the feeding habits of different species. The accumulation of metal in fishes, landed at Diamond Harbour was significantly higher with respect to the species landed at Digha. Further in-depth probing is essential to ascertain the cause of inclination of metals in fish in particular coast.

RESPIRABLE SUSPENDED PARTICULATE MATTER (RSPM) CHARACTERIZATION AT AGRA

Respirable Suspended Particulate Matter (RSPM) characterization study was carried out to ascertain the characterization of RSPM (with size distribution and chemical composition) for the samples collected on May 5/6, 2002. It was found that it had 84-96 % as PM10 fraction, organic fraction was 11.10-14.54% by concentration and inorganic as 85.45-88.90 observed at various selected locations. Further, heavy metals were also observed in higher concentration at Rambagh and Nunhai (mainly Ni and Fe). The basic finding of the study was high inorganic fraction in the samples. Taj Mahal recorded lowest concentrations for all the monitored parameters (Table 7.15).

COLOUR PROBLEM OF RIVER GANGA

River Ganga, the holiest of all rivers and lifeline of North India, has dark coloured water in some stretches. This has not only hurt the sentiments of the millions of people but also has adversely affected the drinking water supply of the towns situated along the river; which included the Metro Towns like Kanpur and Allahabad. The problem got compounded on account of Magh Mela, which falls in the winter only and runs for around a month. On having brought the incidence into the notice, CPCB Zonal office, Kanpur carried out detailed investigation and monitoring and Findings are as below:

Colour problem of River Ganga may be attributed to discharges of various industries in the river Ganga directly or through its tributaries. Kali and Ramganga were found responsible for carrying the colored waste to river Ganga .Both the rivers were surveyed deeply and Water quality monitoring at different stretches of these two rivers were conducted, which is reflected in tables 7.16 & 7.17.

Distilleries and Small Agro based paper mills were among the responsible industries for colour problem located in the region of Meerut, Moradabad and Barilly of Uttar Pradesh and in Kashipur area of Uttranchal State. Detailed survey was conducted to assess the pollution potential of these units. Based on the survey, Uttar Pradesh Pollution Control Board and 18 other industries were issued direction for taking immediate measure to control the colored discharge.

Reasons for colour development

During non-monsoon season, particularly in winter flow in the river Ganga recedes to bare minimum to provide sufficient dilution to the effluent discharges. Problem becomes more severe when there is insufficient discharge downstream to Narora Dam at Ganga.

Number of small agro based paper mills without chemical recovery and distilleries are operating in the catchments area of River Ganga that have very high color potential, which are discharging directly or indirectly to river Ganga in upstream of Kanpur. During winter months industrial discharges were observed to be at peak due to running of Sugar mills and distilleries at full capacity. Though some industries have made arrangement for storing of its effluent during non-monsoon season but generally it is not adequate. The following recommendations were suggested based on the study.

1. Distilleries are required to operate on zero discharge during non- monsoon season. Distilleries that have not opted bio- composting of spent wash should have facility to store its effluent for at least 9 months and in no case effluent be discharged in winter months. A detailed status of each industry about storage capacity of the effluent needs to be collected and compiled. In case it is lesser, the production needs to be curtailed/stopped accordingly particularly during the critical winter months. 2. Only solution with effluent of Small Agro based Paper Mills seems to either installation of Chemical Recovery Plant or switching over to the only waste paper as raw material because paper mill generates lot of effluent (200- 250 m3/tonne of paper) and such large quantity can not be stored as it will require huge space. 3. Minimum critical flow should be maintained through Narora barrage in Ganga during winter to provide sufficient dilution. 4. Strict vigilance is mandatory to the industries discharging their waste in to the tributaries of Ramganga by concerned State Pollution Control Board, as otherwise Ganga becomes almost dry after Narora and any practical solution is difficult to achieve without this. Further other barrages on Ganga and its tributaries may at least release some water to maintain minimum flow in the river. 5. Distilleries and Paper mills should try for colour removal from their treated effluent.

PERFORMANCE STUDY OF ARSENIC REMOVAL PLANT (ARP) FITTED WITH TUBE WELL IN WEST BENGAL

The best solution to human exposure to arsenic contaminated ground water is to provide arsenic free water by tapping surface water sources. This proposition is costly affair as it cover all the arsenic effected area and time consuming. Considering the magnitude of arsenic problem in West Bengal and limitations of surface water, West Bengal government is setting up number of Arsenic Removal Plant (ARP) attached with tube wells in different districts as a short term measure to the problem. Most of removal processes are capable to remove AS (V) from ground water. Therefore effective removal of arsenic as a whole requires complete conversion from AS (III) (always present as observed) to AS (V). This aspect must be taken into consideration otherwise the process becomes slow. Also the level of arsenic content in tube well was observed upto 450 mg/l. Hence the removal technique must be able to take care of concentration of 500 mg/l, if not more. There are some other chemical species in ground water, which may reduce the efficiency of removal process. Considering the above fact, performance of different ARP was studied to evaluate the efficiency in removing arsenic from ground water and their acceptability to users.

The study was also undertaken to assess the efficiency of Arsenic Removal Plants (ARP) installed at different locations in West Bengal. 30 plants were monitored for this study. In this study some of the ARP installed in south 24 parganas and Murshidabad districts were selected for collecting samples to get them analysed in the Zonal laboratory. The analytical results of As, Fe, Zn & Mn both at inlet and outlet of ARP are presented in the Tables 7.19 and 7.20 indicating percentage of removal of these elements of different districts.

Table 7.19 indicated that removal of arsenic by the ARP considered for the study was varying from 26 percent to 97 Percent. Out of 30 Arsenic removal plant, 5 ARP were unable to bring down the arsenic level below permissible limit. If the random survey taken into the reality, the percentage of failure is about 17 percent. Already more than be expected about 170 out of 1000. In some of the ARP it was observed that the level of zinc content in treated water was higher than that of untreated water. This may be due to leaching of zinc from the media. In case of manganese, concentration was higher in treated water excepting leaching from the media. Significant reduction of iron was observed at all the treatment plants. Therefore, iron content in untreated water is the crucial element in maintaining the efficiency of the ARP for a longer time. In addition to removal of arsenic, iron, manganese and zinc, some other parameters like conductivity, TDS, phosphate, nitrate, calcium, total hardness etc. were also measured. Based on analytical results, it was observed that phosphate was drastically reduced in all the ARP and chloride was in higher concentration in treated water. No systematic trend was observed for other variables such as Manganese, Chloride, Fluoride, Nitrate etc. Such random variation in treated water may be due to the composition of media used for removing Arsenic. It was observed clearly that Chloride and Zinc were leached through media. pH value was found higher than that of untreated water due to nature of media used. The data obtained were further processed to evaluate the correlation among the different parameters and percentage of removal of other variables.

As the large number of people are using the treated water with a confidence of the ARP system and there are number of factors playing important role to maintain efficiency and life of ARP, monitoring of the tube well being continued regularly to assess the performance of ARP.

The following are the field observation in maintenance of Arsenic Removal Plants:

Ø Maintenance personnel were not regular in attending their duty in some places. As reported by the villagers, no cleaning is done particularly during summer and rainy season resulting deterioration of water quality.

Ø Wastage of treated water was significant as villagers were not keen to take responsibility. The valve fixed at the mouth of tube well is closed to get the arsenic free water for drinking and cooking and is opened to have water directly from tube well (without treatment) for other purposes. But when valve was non-operational, villagers collected treated water for all uses resulting wastage of treated water.

Ø Back washing of iron-removal column was not very regular resulting yellowish colour of the water. Washers are damaged frequently.

Considering the magnitude of arsenic problems in West Bengal, it is urgently required that with the installation of ARP, proper network for operation and maintenance and monitoring of ARP must be developed to ensure the safe water to people. Also awareness campaign must be accelerated to involve the villagers in arsenic mitigation programme.

ASSESSMENT OF BTX AT MAJOR TRAFFIC INTERSECTIONS IN KOLKATA

Presence of VOC in the ambient air has been the focus of research considering their harmful effect on human health. Recently emphasis has been given on the study of concentration of VOC in the ambient air particularly in the urban areas. Benzene along with toluene and xylene has been a prime target for assessment whose concentrations have been closely related to the use of gasoline and automobile exhaust. Therefore with the installation and operation of BTX analyser, the calibration of the instrument was performed by dilution of gases from permeation tube (VICI Metronics, USA) with zero air and the results obtained were processed to evaluate analytical response based on the parameter are depicted in Table 7.21. Detection limit of some compounds are higher with respect to expected concentration in ambient air. Therefore further calibration with lower range would be carried out to check the uncertainty in ambient concentration level.

Each location, sampling was done for 24 hours at 15 minutes interval. The data generated were processed to study the influence of time and location by statistical technique (i.e. analysis of variance). The BTX concentrations were varying significantly due to location and time. With this variation it may be mentioned that in this study outlier values could not be eliminated from the data and therefore further processing of the data using statistical technique would be done to ascertain the real contribution of variation mainly due to time and location considering uncertainty by BTX analyser. The 8- hourly averages of these concentrations are presented in Table 7.22.

Monitoring is regularly carried out at Tollygunj to assess the distribution pattern of BTX concentration. Month wise distribution (for four months) averaging more than 2500 values in each month are presented in Table 7.23. Based on standard deviation, it may be mentioned that wide variation was observed among all the hours/days. In this situation it is difficult to find out seasonal impact on BTX. However, further attempt would be taken to eliminate the outlier and further processing would be done to ascertain the sources of variation of BTX with one year data.

STUDIES ON AMBIENT NOISE LEVEL AND AIR POLLUTION DURING DEEPAWALI

Ambient noise level monitoring was carried out at various locations in Delhi, i.e. All India Institute of Medical Sciences (AIIMS), Lajpat Nagar, New Friends Colony, East Patel Nagar, Connaught Place, India Gate, Mayur Vihar, Patel Nagar and Kamla Nagar on the occasion of Deepawali festival. At Kamla Nagar noise monitoring was conducted from 17.00 hrs. to 23.00 hrs. while at other lcoations, short duration (half hourly) noise level monitoring was conducted between 17.00 hrs. and 23.00 hrs.. The average Leq noise level value for short duration at 8 monitored locations ranged between 54 dB(A) and 68 dB(A). The Leq noise level at Kamla Nagar ranged between 63 dB(A) and 83 dB(A).

• The Ambient noise level during Deepawali, 2002 at the monitored places are lower as compared to the values, recorded during Deepawali, 2001 except at AIIMS where the values are higher than those recorded in 2001. At New Friends Colony, the data indicates slight increase in the noise level as compared to year 2001. • The long duration noise level monitoring, conducted at Kamla Nagar indicated appreciable reduction in the noise level (from 79 dB(A) to 62 dB(A)) as compared to year 2001 Deepawali festival. • Ambient air quality monitoring was also carried out at ITO Intersection and Ashok Vihar using manual monitoring techniques and at East Patel Nagar (Pusa Road) using the mobile monitoring van. • Nitrogen dioxide levels have shown a significant decrease in year 2002 as compared to the levels observed in year 2001. • Suspended particulate matter (SPM) and Respirable suspended particulate matter (RSPM) have not shown any significant change in year 2002 as compared to year 2001.

The meteorological conditions were not favourable for dispersion of pollutants which attributed to the higher concentration of measured pollutants (SPM and RSPM). During the monitoring period, the weather was calm and most of the time in the day, wind speed was less than 0.3 m/sec. Even during rest of the period, the wind velocity was very low and the maximum hourly average wind speed recorded on Deepawali day was 0.9 m/sec.

ENVIRONMENTAL TRAINING

Training is an important component for Human Resource Development of any Organisation/Institutes. In the area of Environmental Pollution Control, which is an interdisciplinary subject, imparting training is an imperative activity. Environmental awareness among the public and educating current knowledge to the officers working in the Pollution Control Boards are essential steps to have a sound environmental management in the country. Hence the Water (Prevention and Control of Pollution) Act, 1974 and the Air ((Prevention and Control of Pollution), Act, 1981 are also emphasizing that imparting training is one of the major functions of the Central Pollution Control Board. Training in various aspects of prevention, abatement and control of pollution to the identified target groups is important. The target groups include officials dealing with planning, funding and implementation of programmes for prevention and control of pollution in the Central and State Governments, the Central and State Pollution Control Boards, the local bodies, operators of industrial and municipal wastewater treatment plants and NGO's engaged in management of pollution control programmes.

1 ) TRAINING NEED

Pollution control is an inter-disciplinary subject. Graduates, post-graduates in the fields of chemical/civil engineering and pure and applied sciences, do not have any formal training in the field of prevention, abatement and control of pollution. When appointed in Pollution Control Boards, they face a gigantic task before them. Therefore, it is necessary to have them trained and oriented for discharging their responsibilities smoothly and efficiently in areas, such as consent management, and implementation of effluent and emission standards. In addition, there is a need to improve the capabilities of persons already working with Pollution Control Boards. It is necessary that uniform methods of analysis of pollutants and consent granting are adopted and ensured through training for proper and effective implementation of the provisions of the Acts. To summarize, training is needed in the following fields:

• Operation and maintenance of wastewater treatment plants and air pollution control devices; • Management, routine analysis, quality assurance and analytical quality control and maintenance of environmental laboratories; • Water and air quality monitoring system; • Consent management including setting of standards; • Environmental audit, Environmental Impact Assessment and environmental management system; • Specific subjects, such as management of hazardous waste, air/water quality modeling, data processing and legal aspects; and • Computer application for data processing and Internet shuffling for literature collection.

12) MASS AWARENESS AT AGRA

Central Pollution Control Board in association with SBI, GAIL INDIA LTD and Municipal Co-operation of Agra made a joint effort for the visitors of the carnival (Taj Mahotsav, 2003). It displayed the air quality status with instrumentation for the citizens of Agra City along with eco friendly campaign involving students (Environmental Cadets) who played vital role in the spreading and dissemination of information pertaining to environmental preservation. The task was to come united with other corporate bodies to find a solution for the up-gradation of local environment, which was successfully achieved. It helped in linking CPCB with schools and students who are in continuous touch to safeguard the environmental quality of the city.

ENVIRONMENTAL STANDARDS INCLUDING SCHEDULE FOR THEIR ENFORCEMENT REVIEW OF ENVIRONMENTAL STATEMENTS

The Ministry of Environment and Forests, Government of India issued notification for submission of ‘Environmental Statements' (ES) by the industries to the respective State Pollution Control Boards (SPCBs) in April, 1992 and further amended it in April, 1993. ES is a pro-active tool for self-assessment of the industry itself to reduce/minimise pollution by adopting process modifications, recycling and reuse of the resources. The regular submission of ES will indicate the systematic improvement in conservation of resources and environmental pollution control being achieved by the industry. ES can also be used as a set of environmental performance indicators for relative comparison, implementation and to promote better practices.

In order to assess the ES, a project has been taken-up by the Ministry of Environment & Forests for "Review of Environmental Statements Submitted by the industries" and this is being undertaken by the Central Pollution Control Board (CPCB). CPCB, in turn, has included Experts with respect to eleven sectors: i) tanneries ii) bulk- drug industries iii) thermal power stations iv) sugar industries v) cement industries vi) iron & steel plants vii) textile industries viii) pesticides industries ix) petrochemical plants x) pulp & paper industries and xi) oil refineries. The review for sugar industry has been completed and others are in the process of finalisation. The outcome of the exercise has been utilised for setting environmental benchmarks for attainment by all the industries. A similar exercise is being done in other sectors also, to promote systematic improvement.

DEVELOPMENT OF RATIONALE FOR PRESCRIBING LOCATION SPECIFIC STANDARDS

The Central Pollution Control Board took up a project to study the existing practices in prescribing stringent location specific standards by various State Pollution Control Boards and to develop a rationale for the same.

For application of the strategy for location specific standards in the field, two sites In Andhra Pradesh have been chosen i.e. one at Rajahmundry, where plenty of dilution available in the river (Godavari) and the other at Patancheru, where limited dilution available in the river (Manjeera) and large number of industries are situated.

Under this programme, emphasis has been given to assess the assimilative capacity of the environment with respect to air and water pollution. Several models have been reviewed for their suitability and a compilation of the above studies coupled with choice of control technologies, affordability is being considered to formulate rationale. In this process, the experiences of developed countries are being taken through Wisconsin University, USA.

These studies will suggest rationale to be followed in areas where the ambient requirements demand stricter standards.

CONTROL OF VOLATILE ORGANIC COMPOUNDS IN INDUSTRIAL EMISSIONS

The Central Pollution Control Board has identified Volatile Organic Compounds (VOCs), as one of the parameters in industrial emissions, which needs to be controlled to protect the quality of the receiving environment. Considering usage of various solvents and other raw materials in chemical and other specific industries, there is a need to specify control parameters, to govern the volatile compounds.

The selected industrial sectors such as oil refineries, petrochemicals, drugs & pharmaceuticals, pesticides and electronic industries are being studied for existing control measures for VOCs in order to suggest choice of better control technologies/practices to evolve common minimum programme.

Besides, with respect to hazardous air pollutants, there is a need to change the fittings such as valves, pumps, joints, etc which eliminates fugitive emissions due to leakages. A Leak detection and repair (LDAR) programme is required to be introduced. With this understanding, guidelines/norms are being developed.

DEVELOPMENT OF TOXICITY FACTOR AS A GOVERNING PARAMETER The cumulative governing parameters are preferred in environmental sampling such as AOx for all halides. Synergistic and Antagonistic effects of different combination of pollutants will not be addressed, if individual standards are prescribed for each pollutant, thus The governing parameters indicate the necessity of having detailed analysis of each constituent and as such represent the cumulative effects. Thus, such parameters are encouraged for regulatory purpose for ease in checking the compliance. Therefore, with the same perception, a common parameter to represent the toxicity has been developed by the Central Pollution Control Board i.e. Toxicity Factor. It is defined as the dilution factor of the effluent at which 100% survival of Zebra fish ( Brachidanio rerio - Hamilton Buchanan ) ensured for 48 hours. Means, toxicity factor 1 represents the effluent sample without dilution with water, Toxicity factor 2 represents addition of same amount of water with the effluent (1:1); Toxicity Factor 4 represents (1:3 – one part effluent and 3 parts of water) etc .

The tests for Toxicity factor have been carried out with respect to wastewaters arising from pesticides, bulk- drugs, dye & dye intermediates, textiles and tanneries. The results have been processed statistically to assess the present percent level of achievement by the respective industrial sectors.

NATIONAL EMISSION STANDARDS FOR PETROCHEMICAL PLANTS

Air emissions from a petrochemical complex are crucial with respect to pollution control as some emissions are hazardous in nature. Fugitive air emissions from pumps, valves, flanges, storage tanks, loading and unloading operations, and wastewater treatment accounts for 85 to 95 % of total hydrocarbon emissions and are of major concern, due to its volume and carcinogenic nature. Therefore, in order to prioritise the pollution control programme, air pollutants from petrochemical industries have been classified into high, medium, and priority pollutants.

Besides the control technologies, in respect of combustion, process, fugitive, emissions, and flare management have been reviewed for their suitability. The technical inputs from the expatriate experts is also being taken to strengthen the process development of techno-economically feasible standards.

CONTROL OF ACID MIST FROM SULPHURIC ACID PLANTS

Sulphuric Acid plants emit oxides of sulphur and acid mist in the atmosphere. Presently emission limits are prescribed as 4.0 kg/tonne of concentrated acid produced for SO x and 50 mg/nm 3 for acid mist. A study was undertaken to study the possibilities of technology upgradation in existing sulphuric acid plants and use of state- of-the-art technology in new plants to further reduce and control oxides of sulphur and acid mists.

NATIONAL EMISSION STANDARDS FOR PESTICIDES MANUFACTURING INDUSTRY

In pesticides industry, pollution generates in all forms i.e. emissions, wastewater and solid/hazardous waste due to thermodynamic limitations, incomplete reaction, failure of stoichiometric requirement of raw material in the process operation, impurities present in raw materials, etc. Gaseous emissions could be channelized i.e. coming out through vent/stack from specific production process or fugitive in nature (leaks spills etc.), containing several gaseous pollutants. Handling of emissions being sensitive with respect to impact, the emphasis is often given to adopt appropriate pollution control technologies.

Pesticides industry is critical in terms of nature of raw material usage and final products/by-products, which demands special care/attention. It is well established that the process of development of industry-specific- standards consider techno-economic feasibility as the criteria. This criteria demands the review of technologies for control of pollutants emanating from the industries and cost implications due to pollution control equipments and bearing on health & environment. Therefore, looking at the complexity the findings of the study, have been reviewed to suggest the best practices being followed in advanced countries, and options for improvement in terms of technologies ( best available & best practicable ) suitable to Indian pesticide industries.

The Central Board has identified priority pollutants, control technologies, efficiency of control and presently achievable standards. Besides studying the existing technologies, a review of best available technologies has been made through an expatriate consultant considering the best practicable technologies, while considering the economic feasibility for the purpose of arriving at suitable emission standards. The standards proposed will be finalised through consultation process.

DEVELOPMENT OF EMISSION STANDARDS AND STACK HEIGHT REGULATIONS FOR THE VERTICAL SHAFT BRICK KILN VIS-A VIS POLLUTION CONTROL MEASURES

Vertical Shaft Brick Kiln (VSBK) is a vertical type kiln as against the traditional Bull Trench Brick Kiln (BTKs), which has horizontal kiln. The kiln is a natural draft system and uses no electricity for operation. Dry green bricks are loaded manually at the top of the kiln and `measured quantity' of crushed coal of specified size (5-20 mm) is sprinkled over the brick layers, Loading is done in batches after unloading, and each batch consists of 4 layers of bricks. The entire brick batches are supported by bars support provided at the bottom. Normal cycle for brick production varies between 26-30 hrs. During unloading, the entire brick load is transferred to a screw jack system over which a trolley is rested one batch of brick is brought down to facilitate unloading. The support bars are put back to transfer the load back to them and the trolley is brought down. The production capacity of Vertical shaft brick kiln depends on shaft size and number of shafts. About 20 VSBKs are in operation in different regions of the country.

The Ministry of Environment and Forests based on recommendations of the Central Pollution Control Board has introduced emission standards for bull trench kiln during 1996. The standards also envisaged phasing out of moving chimney from BTKs. The Central Board took up the work of evolving emission standards stack height regulations vis-a-vis pollution control measures with active support of TERI, New Delhi.

The performance of VSBKs was monitored during the year 2002. The SPM concentration in the stack was measured between 77-372 mg/Nm 3 . Some of the advantages of the VSBK technology include 1) lower energy consumption (30-60% energy saving); 2) low SPM emissions; 3) less floor area requirement for construction of kilns; 4) flexibility in operation; 5) uniform quality of fired bricks; and 6) ability to operate throughout the year, as against BTKs. Keeping these factors in view, VSBK may offer as an alternate viable technology for moving chimney BTKs low capacity and also for clamps.

The energy performance of the VSBKs shows the average specific energy consumption of VSBKs is 0.9 MJ/kg fired bricks lower than the traditional firing technologies used in the country. The VSBK technology has lower emission levels, thus having good potential in the market.

DEVELOPMENT OF COMPREHENSIVE INDUSTRY DOCUMENT

Development of Comprehensive Industry Document and Environment Standards for Refractory Industry

Refractories are materials, which can withstand high temperature. Their essential function is to serve as structural materials in kilns and thus, their usefulness depends on their ability to maintain mechanical properties at high temperature. In fact refractories are indispensable at almost all ferrous and non-ferrous industries, where high temperature furnaces or kilns are being used. The steel and metallurgical industries greatly depend on refractories involving high temperature application. Refractories are basically heat and corrosion resistant materials used in furnaces. The refractories find application in steel industry, cement, aluminum and glass industry. The steel industry accounts for nearly 75 percent of the consumption of refractories, whereas cement industry accounts around 11 percent. The aluminium and glass industry consumes around six and four percent of refractory products respectively. All other industries consume only four percent of refractory products. Today the refractory production capacity in India is sufficient to cater the national requirement quantitatively but for the quality imports are necessary, especially for steel industry. In India small refractory plants are mostly in unorganised sector, whereas, there are few large and medium capacity refractory plants producing various types of export quality refractory products.

Broadly, the refractory can be categorized based on the installed capacity. On the basis of plant capacity (Thousand Tonnes per Annum, TPA), the refractory plants are categorized as very small scale (up to 5000 TPA), small scale (5001-15000 TPA), medium (15001-50000 TPA) and large capacity (above 50000 TPA) refractory plant.

There are about 6 large, 17 medium scale and 63 refractory plants in the category of small or very small scale sector in the country. Because of sluggish demand from end-user industry and competition from quality imports, some of the refractory manufacturers are facing tough situation while few are on the verge of closure or have been closed. The use of high quality refractories has improved the lining life of furnaces and brought down the specific consumption per tonne of liquid steel, resulting in a lower per tonne usage of refractories, which has adverse impact on traditional refractory manufacturing.

The primary pollutant of concern in refractory plant is particulate matter or dust in air emission apart from water pollution, solid wastes and noise pollution. Particulate matter in terms of fugitive dust generation takes place during crushing, grinding and screening operation in plant. During the study, the present status of pollution in refractory industry and their control, different technologies adopted by Indian refractory industry to combat pollution and finally to develop norms for pollution control. The study has been undertaken in collaboration with National Council for Cement & Building Materials. Ambient air quality, fugitive dust, stack emission, trade effluent, noise pollution & solid waste were monitored during the course of study.

Development of Comprehensive Industry Document and Emission Standards for Hot Mix Plants

Construction of roads play a vital role in Socio-economic development of the country. Ever since the Government of India declared infrastructure developmentas the thrust area, there has been predominant boom in the road construction sector. The construction and maintenance of major portion of the road network is undertaken using conventional hot bitumen-mixes. The hot bitumen mixes are prepared in hot mix plants, which emits significant emission containing particulate matter, sulphur dioxide besides carcinogenic poly-aromatic hydrocarbons. There are more than 1000 hot mix plants of different categories operating in different parts of the country. As per the survey undertaken by Central Building Research Institute (CBRI), Roorkee, plants are of stationary, drum- continuous type. The rated production capacity varies from 6-10 tphr to 10-120 tphr. The locations of these plants keep on changing. Burning of fuel, feeding of aggregates, heating of bitumen from large number of plants are bound to create environmental hazard because of emission of dust and volatile organic compounds like BTX, PAH and PCB's.

Central Pollution Control Board has initiated preparation of Comprehensive Industry Document (COINDS) on Hot Mix Plants in an effort to minimize the adverse environmental impacts by regulating emissions. Information on plant, process details, pollution control technology, emissions, plant location, etc. was collected through extensive field visits as well as questionnaire surveys. The COINDS includes development of environmental standards, suitable techno-economic pollution control device and guidelines for its operation and maintenance.

Development of Environmental Standards for Wheat Processing, Flour Mills, Pulse Grinding and Milling, Dry Rice Grinding and Rice Mills

There are a large number of units spread across the country engaged in pulse milling, dry rice and besan grinding, wheat processing and flour making mills and rice mills. These units mostly use conventional production technologies, which are not oriented towards minimising pollution by incorporation of in-plant control measures. These units give rise to substantial pollution of air, water, noise etc. The Central Pollution Control Board desires to evolve environmental standards for these mills with the help of the National Productivity Council, New Delhi.

The objective of the project is to study the problem of noise, emission and effluent disposal, best available technology not involving excessive cost to prevent, abate and control water, air and noise pollution and to develop standards for noise, emission and effluent including storm water disposal for wheat flour mills, pulses making mills, dry rice, pulses grinding mills and emission standards for rice mills. The scope of work for this project is:

• Literature survey/review of State-of-the art technologies; and • Information collection from State Pollution Control Boards (SPCBs), Industry, etc.

About 20 plants (e.g., five in each category - wheat flour, wheat process, rice mill, rice & pulse grinding, pulse making units) have to be studied in depth by conducting monitoring for the following:

• Characteristics of emission and the quantity; • Characteristics of effluent streams and the quantity; • Characteristics of storm water run of; and • Identification of source of noise pollution and noise measurement.

Technologies are being reviewed for abatement, prevention and control of water pollution, abatement, prevention and control of air pollution, handling of storm water within plant area, control of noise pollution at source, and assessment of adaptability of technologies in Indian context.

Development of COINDS for Tea Processing Industries

India is one of the major exporters of black tea. Tea is grown in certain districts of Assam, West Bengal, Kerala, Karnataka and Tamil Nadu and to some extent in Tripura, Uttaranchal and Himachal Pradesh. In India, average yield of tea was approximately 1670 kg/hectare for the year 2000 and total area under tea cultivation is about 5,00,000 hectares.

Tea is grown in varied type of soil found in tropical, subtropical and temperate climatic conditions. Tea grows best in acidic soils, in areas having a precipitation of about 1,150 to 8,000 mm.

Tea processing consists of the following production units:

• Nursery • Field Planting • Pruning • Plucking of Green tea

For Black Tea Processing, unit operations include:

o Withering (partial removal of moisture); o Leaf disruption (size reduction); o Fermentation (biochemical reactions in the presence of oxygen); o Drying (Completion of moisture removal); o Cooling, Sorting & Grading (fiber removal, grading based on size) and; o Packing (sorted and graded black tea is packed).

Air Pollution Control Source of air emission in the tea industry is basically the D.G. set which is operated only during the power shut- down period. The following efforts are needed from the management towards controlling the air emission.

• Use of low sulphur fuel for combustion purpose in D.G. sets. • Use of tall stack. • Avoiding frequent start-up and shut-down of D.G. sets.

Wastewater Management

Source of wastewater in the tea industry is the domestic sector since the industrial process is basically dry in nature. It is recommended that the domestic waste thus generated be treated in simple treatment system prior to its final disposal. Infact, the wastewater so generated may be treated in Septic Tank. Partially treated effluent from the septic tank should either be disposed of in soak pits or to be further treated in up-flow anaerobic filter (UFAF). The treated effluent from the UFAF could be discharged into any inland surface water or can be used for gardening purpose. Apart from such treatment the management should also practice the following :

• reduce wastage of water; • reduce volume of water use; and • use of treated water for gardening purpose.

Solid Waste Management

The tea plants provide some green manure from leaf-fall; where shade trees are planted their leaves also form green manure. The waste from factories amounting to about 2% of total production may either be recycled in the process, returned to the field as fertilizer or may be reprocessed for by-product recovery. Tea industry produces solid waste, which amounts to about 2.0% of the black tea production. 0.3% of this waste is recycled using some special technique. The balance 1.7% of the solid waste does not have any use value to the black tea producers and is normally sold to a selected reprocessing units where some chemical by products are recovered from this waste.

• The solid waste, which is generated in tea agriculture during pruning/skiffing operation, is used as a fuel. Thus prima-facie it may be opined that neither tea agriculture nor black tea production really generate any solid waste of significance. • The fertilizers, which are normally used during tea cultivation, have minimum if not nil effect on the environment. • Limited chemical study of the leaves, soil & the water used in the system have indicted that the tea leaves, soil & water are all by and large free of pesticide residues. • Tea processing which is the factory operation is more or less a dry process and as such does not generate any liquid effluent. • Odour generated during tea processing within the factory premises is of tea only.

POTENTIAL APPLICATION OF TEAM PROCESS FOR BIOMETHANATION OF DIFFERENT TYPES OF AGRO-SOLID WASTES

Handling and disposal of solid wastes is a major problem because of the harmful environmental effects due to its unscientific handling. There is no proper treatment and disposal mechanism for solid waste and as such it is indiscriminately dumped in low-lying areas. This results in ground water pollution due to the seepage and also release of greenhouse gases such as methane and carbon-dioxide into the atmosphere. The solid wastes from agro-based industries have a high organic content and hence its treatment by the process of bio-methanation is most viable and results in the generation of useful products like biogas and enriched manure. Inspite of the high potential due to the large quantity of generation, we still do not have a well-proven and working design with low retention time and minimal operational problems for the digestion of solid wastes. Keeping these considerations it was decided to test the application of TEAM process for finding bio-methanation potential of organic wastes. The TEAM process is a two stage process consisting of acidification and methanation processes.

Acidification Phase:

In acidification phase, the organic content of the solid waste is leached out to make a high strength liquid, by decomposition of the waste with water. The complete set up of the treatment system consists of rectangular digesters and a reservoir. The acidification reactors are made of mild steel with epoxy coating. The capacity of the digesters is 200 litres. A nylon bag with a mesh size of 0.5 mm was packed with waste and loaded into the digester from the top. Required amount of water was filled, which is sprinkled thrice a day for 15 minutes over the waste bed in the digester by means of a perforated sprinkler situated in the lid of digester. This mixes the liquid well during digestion. Leachate is re-circulated using a small pump. Process continues till there is complete extraction of the organic matter from the waste in the leachate. The digester has a valve at the bottom through which water was re-circulated over the bed of waste at intermittent intervals. Sample was also collected through this port for regular monitoring of various parameters for estimation of extraction efficiency. Depending on the performance of the digester, the extracted liquid leaches out most of the organic matter from the waste. An arrangement for the periodic removal of digested solid waste is provided at the top in the form of a pulley which lifts the bag full of digested sludge and places it on drying floor.

Methanation Phase:

The leachate collected from the acidification reactor is treated in a UASB (Upflow Anaerobic Sludge Blanket) reactor. The gas constitutes of 70-75% methane, 20-25% carbon dioxide. Treated leachate can be recycled back to the acidification reactor for sprinkling. Hence the use of water for acidification process is minimized, unlike in conventional biogas plants.

The leachate treatment for generation of biogas was achieved in a 100 litre UASB reactor made of stainless steel. The height and diameter of the reactor were 1.6 m and 30 cm respectively. The leachate from the acidification reactor was fed into the UASB reactor by means of a peristaltic pump (Miclins India, PP-30 series). The gas flow was monitored by connecting the outlet tube from the UASB reactor to a gas flow meter (Insref-IR 08B). The performance of the reactor was studied at a controlled temperature of 37 0 C. The temperature was maintained by placing the reactor in an insulated chamber equipped with a heat convector that was controlled by a temperature sensor.

The innoculum for the UASB reactor was procured in the form of raw sludge from a local sewage treatment plant. The sludge was acclimatized in a batch reactor to the leachate. A sludge to media volume ratio of 1:2 was maintained during the acclimatization period. The adapted sludge was used in the UASB reactor to treat the organic extract.

The leachate extracted from the food waste was tested in the UASB reactor. For the organic extract from other substrates, in order to assess the biogas generation potential, experiments were conducted in 10 litre bottles with a HRT of 40 days with methanogenic consortia.

Solid Wastes Tested for Bio-methanation Potential:

For the application of TEAM process, following solid wastes which are generated in different agro-based industries were collected and tested using TEAM process:

• Pineapple & apple juices from food processing industries, • Pea shells as one of the seasonal waste; • Press mud from Sugar industry; • Coffee husk and coffee pulp from Coffee processing unit; • Biodegradable waste of vegetarian and non vegetarian hotels from hotel industry; and • Tapioca waste from Sago factory.

Characterisation of the Solid Waste: The characteristics of solid waste is presented in Table 10.1.

Economic benefits from TEAM process

There is dual benefit associated with the waste biomethanation as we get clean fuel (biogas) and enriched manure (Table 10.3). In case of composting of organic wastes manure is the end product.

Table 10.3 Economic viability of TEAM Process Biomethanation Composting Plant Capacity 1 TPD 1 TPD Capital Cost 5 lakhs 1 lakh Annual Biogas generation @ 54 m 3 /d 19710 m 3 -- Amount of LPG replaced 8721 kg -- Savings from LPG @ Rs.30/Kg Rs.261637 -- Manure generation 36500 kg 36500 kg Revenue generation from sale of manure @ Rs. 2/Kg. Rs.73,000 Rs.73,000 Total Revenue generation Rs.3.34 lakhs Rs.73,000 Payback period on plant cost 1.49 years 1.36 years

The payback period of the plant based on both technologies is almost same, indicating higher returns from biomethanation in long run. Further, in case of composting, there are certain limitations such as high land requirements, odor problem, non-suitability of the process during monsoon.

PERFORMANCE EVALUATION STUDY OF ROOT ZONE TREATMENT PLANT AT MOTHER DAIRY

The Root Zone Treatment process effectively purify domestic and industrial effluents according to the law of nature. The term "root zone" encompasses the interactions of various species of bacteria, the roots of the reed plants, soil, air, sun and water. The reed plants (eg. Phragmites communis) carry oxygen through stems into their root systems and thus optimal conditions for the growth of bacteria are created. These bacteria oxidize impurities in the wastewater. Since the process occurs under-ground, the mosaic of aerobic and anaerobic zones exists side-by-side, inducing different types of chemical reactions and balancing bacterial growth. It is estimated that about 5000 types of aerobic and facultative bacteria are present in the root zone filter as compared to only 300 types in conventional biological systems. The whole process of root zone system functions as a mirror of the purifying, self-regulating and simplifying processes found in nature.

Central Pollution Control Board has demonstrated the Root Zone Treatment Plant at Mother Dairy. The scientific study of soil, hydraulics and environmental parameters was carried out for the better understanding of the process in Indian climatic condition, which is essential for development and popularization of this innovative technique. The samples of influent, interim and out flow were analyzed by CPCB for pH, BOD, COD, TDS, PO 4 -P, and TKN. The result were very encouraging for all parameters except TDS, (Efficiency as high as 99%). It was also found that Root zone treatment plant very effectively removes Total and Feceal Colifoms. (The removal efficiency is as high as 99.99%).

It was also concluded by experiments that vertical beds can treat effectively as high as the BOD in the range of 100 to 125 gm/m 2 /day whereas the horizontal beds, the range is between 35 to 50 gm/m 2 /day, which is greater than the limits being recommended currently.

PROSPECTS AND STATUS OF NATURAL DYES

To assess the prospects and status of natural dyes, the study has been initiated pertaining to availability of raw materials, process technologies, current demand, usage and problems in development/manufacture of natural dyes.

COLOUR REMOVAL USING ELECTROFLOCCULATION PROCESS FROM BLACK LIQUOR OF AGRO- BASED PULP & PAPER MILLS

Colour in the effluent from agro-based pulp & paper mills is caused by discharge of black liquor containing lignin. A study has been undertaken on removal of colour from the black liquor by removing lignin using electro- flocculation process. The study has been undertaken on black liquor generated in the laboratory as well as on black liquor collected from the mills manufacturing unbleached as well as bleached grade of paper.

The results of analysis shows that iron electrode has been found effective in removal of colour, lignin and COD. Removal to the extent of 98%(lignin) and 86%(colour) achieved at a pH of 6.0 and temperature of 40 0 C. The optimum time requirement was 40 min for complete electro-flocculation process. The process was carried out at different total solid concentration ranging between 0.5% to 2% and optimum results were at 1.5% concentration.

The trial was also done with the black liquor sample collected from paper mill manufacturing bleached and unbleached grade of paper. The black liquor was subjected to electro-flocculation using different volumes i.e. 2 lit, 5 lit & 7 lit under optimum conditions. A sample of analysis results achieved with 7 m 3 black liquor volume are presented in Table 10.4.

Power Consumption

It was observed that the power consumption is on the lower side if the electro-flocculation is done in two steps by splitting total power consume. In this regard, the studies were conducted in three different volumes of black liquor i.e. 2 lit, 9 lit and 45 lit. The power consumption was 14.5 KWH/m 3 , 10.6 KWH/m 3 and 7.7 KWH/m 3 .

Findings

• The electro-flocculation process was found technically viable for removal of colour, lignin and COD from effluent of agro-based pulp & paper mills. • The parameters have been optimized at lab scale for the electro-flocculation process including power consumption. • The process can be applied for any type of black liquor from rice straw, bagasse and wheat straw. • The cost economics including operational cost still to be find out. • There are two major factors which governs the cost of treatment i.e. cost of electrodes and cost of electricity.

POLLUTION CONTROL MEASURES IN PLASTICIZER INDUSTRIES

As per the list of industries compiled by MPCB, GPCB & DPCC, most of the Plasticizer industries (Total 21 - mostly small scale units) are located in west zone of the country) have been visited and monitored in respect of water and air emissions.

The plasticizer industry, producing different types of Plasticizers (which allows the flexibility to plastics), has high potential for water and air pollution. The plasticizer industry generates low volumes of effluents with high organic load. This industry has more of fugitive emission problems (particularly, organic fumes) rather than the source emissions. The units falling under this category have provided varied degree of effluent treatment facilities; however, most units have zero-discharge condition, which makes it vulnerable for the effluent treatment, reuse, and disposal. The detailed report is under preparation.

POLLUTION CONTROL IN SLAUGHTER HOUSE

The slaughter houses are mainly water polluting units. They also cause air pollution by way of foul smell and generate substantial quantity of solid wastes. It is therefore, necessary that these units should install proper treatment systems.

The Central Pollution Control Board is pursuing State Pollution Control Boards and Pollution Control Committees to take action against slaughter houses and related units. In order to speed up pollution control implementation, directions have been issued to the State Boards under Section 18(1)(b) of the Water (Prevention and Control of Pollution) Act, 1974 for taking action in case of slaughter houses and related industries. The State Boards have been directed to issue the following directions to slaughter houses/meat processing industries, which don't have requisite effluent treatment plants:

• The slaughter house/ meat processing industry shall submit a time schedule for installation of effluent treatment plant to State Pollution Control Board within one month from the date of issue of the direction; • The slaughter house/ meat processing industry shall install requisite effluent treatment plant as per the time schedule agreed by State Pollution Control Board; and • The slaughter house/ meat processing industry shall submit a quarterly progress report on installation of the effluent treatment plant to State Pollution Control Board.

DEVELOPMENT OF GUIDELINES FOR ENVIRONMENTAL CLEARANCE TO PROPOSED DISTILLERIES:

The Special Secretary, MoEF constituted a group of experts and officers of CPCB & MoEF to recommend criteria/technology for environmental clearance to the proposed distilleries. Experts and officers of CPCB & MoEF had discussions on various issues and recommended following:

The Committee has classified distilleries in two groups based on their capacity of alcohol production :

Class I Distilleries having capacity of less than 45 kld

Class II Distilleries having capacity more than 45 kld.

For class I distilleries, i.e. distillery having capacity less than 45 kld, following alternative technologies are recommended to be adopted for treatment and disposal of spent wash for allowing new distilleries :

1. Bio-methanation followed by composting; 2. Composting of spentwash directly; 3. Evaporation and drying/incineration of spent wash; and 4. Bio-methanation followed by evaporation and drying/incineration o Distilleries be allowed to adopt evaporation followed by composting of concentrated liquor. This will have a beneficiary effect of reducing press mud requirement. o Storage capacity to store spent wash be restricted to less than one month so as to minimize odour problem.

For Class-II distilleries; i.e. distilleries having capacity more than 45 kld, the recommendations are as follows:

The proposed distilleries having capacity more than 45 kld be allowed to operate with evaporation and drying/incineration technology for the treatment and disposal of spent wash. This may be alongwith or without bio-methanation process. Alternatively, the industry may also opt for evaporation and composting of the concentrated spent wash.

Quantity of Spent wash from Distillery Plant

The generation of spent wash should be limited to 8-10 kl/kl of Rectified Spirit(RS). This may be achieved either by adoption of continuous fermentation technology or by providing reboiler. In the case of incineration preceded by bio-methanation system, spentwash generation upto 15 kl per kl of RS production may be allowed.

In case, the distillery is situated near the coastal area, its disposal with proper treatment will have to be analysed in detail considering marine biological aspect of the area as well as other considerations, i.e. dilution effect of the sea water etc.

Development of requirement for Compost plant in Distilleries

The three Member Committee constituted by the Hon'ble Supreme Court in the matter of Distilleries in Haryana State had taken assistance of technical experts, consultants, officers form CPCB & HSPCB to decide the requirements/specification for surface compost process utilizing distillery spent wash and press mud.

DETERMINATION OF OPTIMUM WATER CONSUMPTION LIMIT FOR BULK DRUG MANUFACTURING INDUSTRY

Bulk-drug industries consume considerable quantities of water for their process and non-process uses. As a rapid growing industry, the product profile is changing and the quantity of water usage is also having wide ranges. Therefore, a study has been taken-up by the Central Board to review the existing patterns of the water use. Options for optimisation and to arrive at optimum water consumption limit for the bulk drug industry, so that the industries which consume water less than the limit and having adequate ETP facilities can avail the water cess rebate offered under the provisions of The Water (Prevention and Control of Pollution) Cess Act, 1977. Looking at the wide variation in the water consumption patterns, the industries have been classified into four groups for evaluation as presented in Table 10.6.

Table 10.6 Classification of Bulk Drug Industries for Evaluation Group I High production volume – High number of manufactures Analgesics and Anti-pyretics Anti Asthmatics Anti Dysentry Sulpha Drugs Vitamins Anti Bacterial Synthetic Anti Biotics Anti TB

GroupII II High production volume – Low number of manufacturers Fermented Anti Biotics

Group III Low production volume – High number of manufacturers Anaesthetics Anti Histamines Anti Malarial Gastro-intestinal Anti Diabetics Anti Helmentics

Group IV Low production volume – Low number of manufacturers Corticosteroids CNS Stimulants Diuretics Tranquillisers and Sedatives Cardiovascular Anti Leprotics Anti Filarials

From the questionnaires received from the bulk drug industries, it is observed that most of the water is consumed in the utilities and domestic areas as compared to the manufacturing process areas. The ratio of process water consumption to total water consumption is 20 – 25% in most of the industries and huge amount of water used in utilities are not being re-used/re-cycled. Options for water conservation are being identified to optimise the water use and to suggest the optimum water consumption limit(s).

POLLUTION CONTROL IN INDUSTRIES

Colour Removal from Black Liquor of Agro-Based Pulp & Paper Mills

Colour in the effluent from agro-based pulp & paper mills is caused by discharge of black liquor containing lignin. A study has been undertaken on removal of colour from the black liquor by removing lignin using electro- flocculation process. The study in the laboratory has been undertaken on black liquor generated as well as on black liquor collected from the mills manufacturing unbleached as well as bleached grade of paper.

The results of analysis shows that iron electrode has been found effective in removal of colour, lignin and COD. Removal to the extent of 98% (lignin) and 86% (colour) achieved at a 6.0 pH and temperature of 40 0 C. The optimum time requirement was 40 min for complete electro-flocculation process. The process was carried out at different total solid concentration ranging between 0.5% to 2% and optimum results were at 1.5% concentration.

The trial was also done with the black liquor sample collected from paper mill manufacturing bleached and unbleached grade of paper. The black liquor was subjected to electro-flocculation using different volumes i.e. 2 l, 5 l and 7 l under optimum conditions.

Pollution Control in Ginning Industries Cotton ginning is an interface between farming and industrial sectors from cotton to textile production, and engaged in the process of separation of cotton fibres from Cotton balls. Ginning industries are mostly small units located in semi-rural and small towns. During the ginning process, dust fibres and lint are generated which cause air pollution. Studies were carried out in ginning industries to identify pollution problems and suggest remedial measures.

Prospects and Status of Natural Dyes

To assess the prospects and status of natural dyes, the study has been initiated which includes availability of raw materials, process technologies, current demand, usage and problems in development/manufacture of natural dyes.

Review of Standards for Oil Refineries

The standards for discharge of effluent and emissions from oil refineries were notified in the years 1986 and 1990 respectively. There is need to include additional parameters such as oxides of nitrogen, volatile organic compounds etc. Since developments has taken place in the refining technology and pollution control. New process units are also being added to meet the improved fuel quality standards.

The project has been taken up for the revision of the standards for oil refineries based on performance as well as technology based approach and include mass based and concentration-based standards for various process operations of refineries. A leak detection and repair (LDAR) programme and specific requirements for minimizing vapour losses from storage tanks and product loading/unloading facilities are being considered to regulate the fugitive emissions of volatile organic compounds.

Control of acid mist from Sulphuric Acid Plants

Sulphuric Acid plants emit oxides of sulphur and acid mist in the atmosphere. Presently emission limits are prescribed as 4.0 kg/tonne of concentrated acid produced for SO x and 50 mg/nm 3 for acid mist. A study was undertaken to study the possibilities of technology upgradation in existing sulphuric acid plants and use of state- of-the-art technology in new plants to further reduce and control oxides of sulphur and acid mists.

Industrial Pollution Control along the river Ganga (GAP Phase-I)

The follow-up programmes in respect of 68 industries identified under Ganga Action Plan (GAP) Phase-I were initiated by CPCB soon after the introduction of GAP in 1985. The pollution control status of these 68 industries as on March 31, 2003 is provided in Appendix-XI.

The industrial pollution control programme along the river Ganga got further intensified with the launching of the Central Action Plan in August, 1997, for control of industrial discharges along the rivers and lakes in the country. This programme resulted into identification of 119 more industries along the river Ganga that required priority attention for the control of their effluent discharges. The pollution control status of these 119 industries as on March 31, 2003 is provided in Appendix-XII.

Industrial Pollution Control Along the Rivers and lakes

851 defaulting Grossly Polluting Industries located along the rivers and lakes in the country have been identified for priority actions under this programme, which was started in August 1997. The follow-ups for the implementation of the programme, was intensified and at present only five industries are defaulting and the matter is in the Hon'ble Court in respect of three industries and action has been taken against the two remaining defaulters. The State-wise summary status of the 851 industries as on March 31, 2003 is given in Appendix-XIII. The year-wise reduction in the number of defaulters since the start of the programme in 1997 is as shown in Figure. 10.2.

Operational Status of the ETPs installed by the industries located along the rivers & lakes

Directions under Section 18 (1) (b) of the Water (Prevention and Control of Pollution) Act, 1974 have also been issued by CPCB to the SPCBs/PCCs to send quarterly reports on the operational status of ETPs of all the grossly polluting industries located along the rivers and lakes. The directions also required the SPCBs/PCC of Uttar Pradesh, West Bengal and Delhi to send separate such reports of all the water polluting industries (irrespective of size and category) existing in Kanpur, Calcutta and Delhi respectively.

The operational status of 790 industries received from 22 SPCBs/UTs. Out of these 790 units, 619 have installed the requisite treatment facilities, 157 are closed, five are in the process of installing the requisite treatment facilities and there is no effluent treatment facility existing in case of the remaining nine industries.

Out of the 619 units which have installed ETPs, 440 are operating satisfactorily and the operation of the treatment facilities is not satisfactory in respect of 179 units. SPCBs/PCCs have been asked to take action against the units where the operation of treatment facilities is not satisfactory and direct the industries for up- gradation of the design/improvement in the operation of the ETP.

Industrial Pollution Control along the river Yamuna

The water quality of river Yamuna got affected due to discharge of effluents by the industries located upstream Delhi along Western Yamuna Canal and complaints were received from the Delhi Jal Board regarding the presence of ammonia in high concentration and subsequent shut down of the Nangloi and Haiderpur water works affecting the supply of drinking water to most parts of Delhi.

The CPCB has directed Haryana SPCB under section 18 (1) (b) of the Water Act, 1974 requiring the State Board to ensure stoppage of any discharge of industrial effluent as well as untreated sewage into the Western Yamuna Canal. The Chief Engineer, Yamuna Water Services has also been directed not to release water from the Yamuna Nagar Head Works into the abandoned Western Yamuna Canal and to ensure that the flow of any water from this canal does not join the main canal at the Munak regulator.

Reports have been received from SPCBs of Goa and Chattishgarh. Reminder sent to the remaining SPCBs/PCCs for obtaining the reports.

ASSESSMENT OF POLLUTION POTENTIAL IN ZARI INDUSTRIES AND PROBABLE TECHNO-ECONOMIC SOLUTION FOR ITS TREATMENT & SAFE DISPOSAL IN SURAT

There are around 2000 to 2500 benches of gilding units in Zari manufacturing industries in Surat City of Gujarat. These industries are located in the heart of the city. The process involves use and handling of toxic chemicals like acids, Cyanides etc. Due to sheer secrecy and unhealthy competitive practices, Zari industries of Surat could never get the shape, which it could have been acquired by way of upgradation in technology, better processes, effective use of resources and of course less water. To explore the present status and probable solutions for associated environmental problems of Zari industries, the CPCB West Zone office has carried out the study in association with M/s Pollucon Laboratories, Surat.

The study revealed that the use of Cyanide in the process is as high as 3 MT/month in Surat City. The average consumption of Cyanide is 30-50 kg/month/unit. The use of concentrated Sulphuric acid in Zari industries of Surat is around 2.5 KL per month. In addition to this there is a significant quantity of Nitric and Hydrochloric acid is also used on the process units. These chemicals as such do not go with the final product i.e. Zari and hence find the way in either water or air environment. These facts reveal the gravity of the situation in Zari industries.

The main pollution is in the form of effluent, which content high amount of Copper, Cyanide and Silver. The wastewater to be drained out from the different stages were characterized and it is found that the concentration of theses parameters varies between 4.91 to 7460, 51.5 to 572 & 2.5 to 86 mg/l for Copper, Cyanide and Silver respectively. During the survey it is understood that causality occurs in Zari industries due to inhalation of Cyanide fumes at the time of Silver salt precipitation (Neutralization) from the effluent.

Being in congested area, it is not possible for individual units to provide treatment facility for the wastewater. The adequate common treatment system supported with appropriate collection mechanism is best suited for the treatment of the effluent generated. Similarly, immediate action is required to provide for proper hood, ducting, scrubbing and exhaust system for venting the toxic fumes/gases.

REVIEW OF PROBLEM AREAS IN GUJARAT & MAHARASTRA

Vapi

Action Points at Vapi have been complied, by now. However, the drains (particularly, the Bill Khadi) continued to be flowing with effluent. A Meeting regarding the Action plan on Air Pollution at Vapi was attended, which was prepared by GPCB, in consultation with CPCB and other concerned State Departments.

Ankleshwar

Most of the Action Points at Ankleshwar have been complied, some revised points of action suggested. - Improvement in respect of drainage network and solid waste management, also – Effluent conveyance project of pipeline (35 km long) is in advanced planning stage

A Meeting on Action plan on Air Pollution for the Ankleshwar was attended, which was prepared by GPCB, in consultation with CPCB and other concerned State Departments.

Tarapur

Tarapur Industrial Estate in Maharashtra state has been identified as a problem area because of high pollution potential generated by the industries, especially, chemical industries located in Tarapur. The action plan for the problem area has been prepared and various efforts have been made to implement the action plan. The time targeted action plan was prepared to solve the air pollution, water pollution and solid waste management problems in the industrial estate. Organizations like, Maharashtra Pollution Control Board, MIDC & Tarapur Industries Association are responsible for implementation of the action plan. As a follow up action Central Pollution Control Board reviews the action plan time-to-time.

Though the concerned agencies in the area are making efforts for implementation of the action plan. However, there are lacunae in implementation part. During the study it has been found that, the concerned authorities are not maintaining industrial area in a environmental friendly manner, the Hazardous waste are dumped here and there, effluent are flowing in open drain, odour nuisances, soil contamination etc. are the common phenomenon. The MIDC drainage lines are under-designed and not being maintained properly too. At some places the manhole & pipelines of MIDC drainage were found to be broken and effluent was finding its way in to earthen drains, which ultimately meets the Arabian Sea. Industrial solid/hazardous waste was also found to be dumped on the roadside at various places in the area in addition to the MIDC solid waste dumping plots in the industrial estate. The CETP is also dumping its sludge at unknown places. Patches of coloured effluent and flow of acidic coloured water in natural earthen drain was observed at various places, which shows that the activities like illegal discharge of effluent and dumping of solid waste in haphazard manner are in practice by the industries. Similarly, the acidic pH was also observed in MIDC effluent collection sump ranging between 2 to 4. It is understood that the raw water supply from April 2002 to July 2002 to the member CETP unit was around 6 MLD and the effluent generation was around 3.5 MLD. However the effluent quantity reaching to the CETP is only 87,000 M 3 /day, which is hardly 1/4 th of the total quantity. This shows that many member industries are discharging their untreated effluent into MIDC drainage line and damaging the effluent carrying system.

PROSECUTIONS LAUNCHED, CONVICTIONS SECURED AND DIRECTIONS GIVEN FOR CLOSURE OF POLLUTING INDUSTRIES

Salient observations of the monitoring carried out during the financial year 2002-2003 are as follows:

• An average of only 30% of waste receptacles (dhalaos/ dustbins) in Municipal Corporation of Delhi (MCD) areas are found properly maintained. The figures for New Delhi Municipal Council (NDMC) and the Delhi Cantonment Area are 90% and 40% respectively. • Steep deterioration in maintenance of waste receptacles has been observed in the following zones of MCD: o Central Zone o Civil Lines Zone o Sadar-Paharganj Zone o Shahdara (North) Zone o Shahdara (South) Zone • Lifting and transportation of garbage from waste receptacles in MCD suffer from inadequate number of vehicles, thus causing major obstacle in improvement of MSW management in Delhi. • All the three landfill sites of NCT of Delhi (Bhalswa, Ghazipur and Okhla) have exhausted their capacity. Efforts to identify and develop new landfill sites are yet to gain required priority and momentum from the concerned authorities. Pending this development, more than 1.5 million MT of MSW is being dumped in these exhausted sites without proper care and precautions to avoid public health and environmental impacts.

The MSW compost plants operated by MCD and NDMC are dilapidated and operating at less than 15% of the installed capacities. The privately operated new compost plant at Bhalswa is also in a state of redundancy due to various operational and management issues.

According to the petitioner there are about 55,000 brick kilns in the country and the majority of the kilns are made of primitive design and are known as moving Bull's Trench Kiln (BTKs) and firing techniques employed in these BTKs results in high air pollution levels and greater consumption coal. The air pollution caused by these moving Bull's Trench Kilns affect the health of residents and caused damage to the crops and plants.

The High level of pollution is caused by these moving BTKs. The Central Pollution Control Board developed standards and stack height regulation for the brick kilns. Under the prescribed norms, the moving BTKs were to be replaced by fix chimney brick kilns. The standards developed by Central Polution Control Board were notified by the Ministry of Environment & Forests vide EPA Notification (G.S.R. No. 176 (E), dated 2 nd April, 1996).

The Punjab State Council for Science and Technology developed a modern design of fixed chimney brick kilns conforming to the emission standards laid down by the Ministry of Environment & Forests. During the demonstration it was shown that the design developed by the Punjab State Council for Science and Technology controlled the air pollution to the large extent. It was demonstrated that SPM levels were found in the range of 187-369 mg/Nm 3 which was well below the stipulated norms of 500 mg/Nm 3 .

The Central Building Research Instituted, Roorkee also developed a modern design of fixed chimney brick kilns conforming to the emission standards laid down by the Ministry of Environment & Forests. It is alleged by the petitioner that the MoEF extended the time limit for change over from existing moving BTKs to the fixed chimney brick kilns till 30.6.1999 vide EP Notification (G.S.R. No.7, dated 22.12.1998). The MoEF again extended the time limit for chane over from existing moving Bull's Trench Kiln to the fixed chimney brick kilns till 30.6.2000 vide EP Act Notification, dated 5.10.1999. The MoEF again extended the time limit for change over from moving BTKs to fixed chimney brick kilns till 30.6.2001.

The Petitioner has alleged that inspite of new and modern design of fixed chimney brick kilns, conforming to the emission standards as laid down by the MoEF, being developed by premier research organization, the MoEF in total disregard to the air pollution caused by the moving BTKs and in collusion with the honour of kilns repeatedly extended the time limit from moving BTKs to fixed chimney brick kiln. The ministry of playing havoc with the environment and the health of the citizen of this country. The Central Pollution Control Board has filed its counter affidavit stating therein that the moving chimney Bull's Trench Kilns (BTKs) are based on primitive technology and crude firing practice and cause air pollution and great damage to the crops and orchards and causing health problem to the labourers and inhabitants living nearby. The Central Board has also submitted in its affidavit that the extensive research carried out by the various instituted and organisation to improve the design of brick kilns as to the conform the emission standards laid down by the MoEF. The consultants were developed designs for small, medium as well as large brick kilns and designs are found environmentally friendly and also control the air pollution and conform to the emission standards set by the Ministry of Environment & Forests.

The Union of India in its affidavit mentioned the reason for extending the limit for change over from moving chimney kiln to fixed chimney kiln. However, during hearing before the Chief Court, the Counsel for the petitioner submitted that inspite of affidavit filed by Union of India they have extended the time limit and this is a case of perjury. The Hon'ble High Court directed the Union of India to file affidavit justifying the extension of time limit. The Hon'ble High Court also directed the Union of India to file status report by way of affidavit. The case is pending before the Hon'ble High Court at New Delhi.

"Copy of this application be also forwarded to Shri Bhure Lal who should constitute an agency which would independently carry out random inspection at the petrol pumps, oil depots and tank lorries in Delhi and give a report with regard to the quality of petrol and diesel available there. It will not be necessary for such an agency to give advance notice before lifting samples as it will be helpful if there is an element of surprise".

To ascertain the existing procedures for checking adulteration of fuel and to formulate a work plan for conducting surprise checks and independent fuel testing, EPCA discussed the matter with the representatives of the Anti-Adulteration Wing of the Ministry of Petroleum and Natural Gas (MoP&NG), Department of Food and Civil Supplies, Govt. of NCT Delhi, Society for Indian Automobile Manufacturers (SIAM) and the Society for Fuel Testing Laboratory (FTL) Noida. EPCA submitted an interim report to the Hon'ble Supreme Court and Subsequently, EPCA authorized the Centre for Science and Environment (CSE) as an agency to carry out random inspection of petrol pumps, oil depots and tank lorries. CSE carried out inspection of fuel quality at fuel dispensing stations, oil depots and tank lorries independently from December 20, 2001 to January 18, 2002 in the National Capital Territory of Delhi and in the National Capital Region. During the inspection, the State Level Coordinator and Regional Level Coordinator of the Oil Companies provided logistic support for sampling. The petrol and diesel samples collected from various locations were analysed in the Fuel Testing Laboratory at NOIDA. The CSE collected 192 samples and handed over 145 samples to the Fuel Testing Laboratory (FTL) at NOIDA for analysis. Major findings and recommendations of the report are as follow:

The study clearly shows that unless we take serious steps to improve the system to prevent and check adulteration, we will not even begin to touch the profitable business of adulteration. The current system is compromised from testing methods that are not adequate to detect adulteration to penalty systems designed to let the manufacturers go scot-free. Distorted prices continue to encourage adulteration. Some of the suggested measures are as follows: a) Make oil companies accountable for the quality of fuel at the retail end

Any extent of vigilance and surveillance will be meaningless unless strict liability is imposed on the oil companies to take full responsibility for the quality of fuels they sell at their retail outlets. As of now, the responsibility and penalty are all fragmented along the supply chain. Though retailers and the transporters are penalised by the oil companies if malpractices occur, the oil companies are not held accountable. To put it simply consumers cannot sue the oil companies for adulterated fuels. Unless this is done checks and balances in the system will not work effectively to prevent malpractices at any level. The best way that consumer pressure can be intensified on the oil companies is to develop a system of public rating of the retail outlets by the name of the oil companies on a monthly basis based on an independent inspection, testing and audit of the outlet. In a competitive market there are multiple oil companies rivaling for market share. This will become more severe with decontrol of the petroleum sector soon. In such a situation protection of brand name would be most critical for the oil companies to guard their market share. Therefore, quality based public rating of the retail outlets by the name of companies would work best in disciplining the supply chain and preventing the widespread malady. b) Improve testing procedures and tighten fuel quality standards

Immediate attention should be paid to tightening the fuel quality standards and regulating some key parameters that are not done today like aromatics, olefins in petrol, and PAH in diesel. Even the broad range that is allowed under the current specifications should be adequately tightened. Tighter the net easier it is to catch dubious samples. c) Develop alternative testing procedures for more accurate detection

For more accurate detection alternative testing methods and protocols should be adopted straight away and applied for surveillance. It is possible to create a library of different refinery samples of automotive fuels and possible adulterants. With the help of the standard library chromatogram it will be much easier to detect fuel adulteration.

• Pricing of CNG

The Hon'ble Supreme Court while hearing affidavit filed by the Indra Prastha Gas Ltd. on May 9, 2002, passed the following order:

"Bhure Lal Committee is requested to investigate the prices of CNG as done by the IGL and give report to this Court whether there is any justification for the figure of Rs. 16.83 per kg. In giving this report, the Bhure Lal Committee should take into consideration the price at which petrol, diesel and kerosene are sold in Delhi. It will also indicate as to what is the extent of the subsidy or cross subsidization, if any given by the Central Government in respect of petrol, diesel and kerosene as compared to CNG.

The report of the Bhure Lal Committee be submitted within eight weeks. The Indraprashtha Gas Limited and the Union of India shall furnish to Bhure Lal Committee any particular which are asked for by the said Committee. The Bhure Lal Committee will be at liberty to take assistance from any Cost Accountant or any other expert in the matter."

In order to implement the order, EPCA decided to call for submissions from the Ministry of Petroleum and Natural Gas (MoP&NG), Indraprashtha Gas Ltd.(IGL), Gas Authority of India Ltd.(GAIL), Mahanagar Gas Limited, Mumbai, Gujarat Gas Limited, Oil and Natural Gas Commission, Petronet LNG Limited, British Gas Co., Ministry of Finance and Ministry of Environment & Forests. Besides written submission, EPCA held discussion with the concerned agencies. IGL, GAIL and MoP&NG also made presentations before the Authority. Based on these inputs, a report titled "Getting the Price Right: Promoting Environmentally Acceptable Fuels Through Fiscal Measures" was prepared for submission to the Hon'ble Supreme Court. The summary recommendations of the report are as follow:

A. Pricing of CNG in Delhi

1. The cost accountants consulted by the EPCA from the Institute of Public Auditors of India have examined the cost data provided by the IGL and have made the following observations: a. Need for rationalisation of costs and detailed scrutiny. b. IGL should scrutinise its expenditure to bring in more efficiency and further reduction in operating costs and fixed costs. In particular, IGL must work to economise its expenditure on administration, salaries and repairs and maintenance. c. Cost implication of the agreements with respect to annual maintenance would need review, as in the current agreements the savings cannot be quantified. The Auditor's report therefore emphasises on the scope of further improvement in operational efficiency of the company. 2. No one can contest that all efforts should be made to improve the efficiency of the operations. However, in a fixed cost of Rs 4.91 a 10 per cent improvement in efficiency would save about 50 paise per kg of gas. At the same time in such operations real efficiency can be achieved only after the operations have stabilized. 3. IGL has justified the price hike from Rs 13.11 to Rs 16.83 arguing that sales revenue would not increase adequately to cover up increased costs of operation and infrastructure development. Therefore, optimised utilisation of infrastructure, better capital planning and increased sales should be the focus. Better sales and efficiency in operations in future should help in keeping further price increase in check. 4. Need for higher return on equity is yet another justification given by IGL. In its affidavit to the Hon'ble Supreme Court, IGL has claimed that its return on equity is 10 per cent. As mentioned earlier increases in sales in future could provide opportunities to reduce the price of gas to consumers. 5. Towards this objective, it is important for government to recognize the developmental imperative of IGL and that investments in creating a gas infrastructure will earn long term gains – both in terms of high returns as well as high developmental, economic and societal rates of return. Therefore, appropriate fiscal policies and the use of economic instruments are needed to support this objective.

The government should provide a tax break on CNG for a certain period of time and subsequently, maintain an effective differential vis a vis other conventional fuels. The excise duty, which has been increased from 8 per cent to 16 per cent should be totally waived. This will not affect revenue generation of the government from this small niche market to any appreciable level. But this will amount to a decrease in the price of CNG by Rs. 2.32 per kg. This move should be subsequently supported by a favourable taxation policy. This should be further complimented with vehicles based incentive programmes.

6. The more serious problem is that the project has been conceived under tremendous time pressures, without adequate support. Therefore, It is important for IGL to now take stock of its opportunities and plan carefully to ensure that it is able to dispense gas to the growing market in Delhi. This is critical for the implementation of the CNG project in Delhi. 7. There is scope for improvement both in terms of increased sale and in improving operational efficiencies to keep the price stable in the future. If the cost of present investments had to be cushioned then the government should have intervened with tax incentives and low interest loan package for IGL. As mentioned above, a major component of the price is excise duty. In addition to this, the interest burden as evident from the cost details provided by IGL is expected to increase substantially in the coming years: from 3 per cent of the expenditure to roughly 11 per cent of the expenditure by 2003-04. If IGL has recourse to low cost funding from Oil Industry Development Board (OIDB), under the Ministry of Petroleum and Natural Gas, it will substantially reduce the financial costs and obviate pressure to increase prices. In addition to this the government should implement tax break, phase in differential taxation and provide other tax incentives to IGL to make CNG more competitive with fuels it is replacing like diesel.

Fiscal policy for promoting environmentally acceptable fuels

1. It is clear from the review of the fuel taxation policies around the world that "favourable" taxation is an important instrument to maintain the price differential to encourage environmentally acceptable fuels. EPCA recommends that the Indian government must also frame a fiscal policy to allow for higher price competitiveness for environmentally acceptable fuels with competing conventional fuels. 2. In the context of Delhi and other critically polluted cities of India it is important to remember that CNG will directly compete with diesel more than petrol. As a result, the taxation policy should be designed in a manner that an appropriate and effective price differential is maintained with diesel. Therefore, in order to address the CNG taxation it is also important to address diesel taxation. In Delhi today the percentage difference between petrol and CNG prices is as high as 42 per cent in contrast to a meagre difference of 6 per cent between diesel and CNG. While tax on CNG should be lowered, tax on city diesel should be increased simultaneously. 3. It must be noted that the government is already using fiscal measures, such as tax adjustment in the excise duty, to manage the volatility in the diesel and petrol prices. For instance, given the high current prices of diesel and petrol, it has reduced the excise duty from 16 per cent to 14 per cent on diesel and 32 percent to 30 percent on petrol, to reduce the burden on the consumers. 4. EPCA recommended that the government should also provide a tax break on CNG for a certain period of time. Amount of gas that is coming in for transport and city distribution is a very small fraction of the total gas market in the country – less than 2 per cent. The excise duty, which has been increased from 8 per cent to 16 percent, will earn a mere Rs 42 crore from the Delhi CNG market during 2002-2003 and can therefore be waived off till the time the market is established. This will not affect revenue generation of the government to any appreciable level. But this will amount to a decrease in the price of CNG by Rs. 2.32 per kg. Subsequently, differential taxation should be phased in. This should be further complimented with vehicle based incentive programmes as already directed by the Honorable Supreme Court. 5. The government is already poised towards deregulating the gas prices and gas sector reforms. But such moves will have to be examined carefully in the context of CNG as an autofuel. It is not within the purview of our report to look into these issues though we understand that there is need for an appropriate fiscal instrument that will enable natural gas and CNG to remain competitive in a market driven scenario. It is important that the government reviews the gas pricing system, status of gas sector reforms and practices in other countries to implement favourable taxation policy to promote environmentally acceptable fuels. 6. With deregulation and reforms underway, there is little elaboration of the issue of CNG as an autofuel in official policies. The current focus of the pricing system is on industrial and power uses of gas, where it is competing with fuel oil and naphtha. But there is no discussion on policy intervention needed to make CNG competitive vis a vis its competing fuels especially when price deregulation happens. If pricing and market reforms are not synchronized with appropriate regulatory support it may lead to steep escalation in gas prices after deregulation and may make it difficult to sustain favourable taxation policy especially vis a vis competing fuels like diesel that are likely to remain cheaper. This requires immediate scrutiny. 7. The government must urgently formulate a policy for CNG and other environmentally acceptable fuels for the transportation sector. The issue is not the price per se , but the comparative price of the fuel it is replacing. In the deregulated scenario if the price of diesel keeps fluctuating and remains too close or even lower than CNG it will have a negative impact on the CNG programme. Therefore, the government must urgently formulate a policy to promote environmentally acceptable fuels like CNG by using economic instruments to maintain the critical differential between clean and dirty fuels.

• Development of Forests in Land Acquired by Delhi Government

The Hon'ble Supreme Court in I.A. No. 756 in Writ Petition ( C ) No. 202 of 1995 in the matter of T.N. Godavarman Thirumulpad Vs. Union of India and Others has passed the following order on 9 th May, 2002:

"We direct the Bhure Lal Committee to examine the possibility of development of forest and large tracts of land which have been acquired by the Delhi Administration and the Delhi Development Authority and which are still lying undeveloped. Liberty will be given to the Delhi Development Authority and the Delhi Administration to place before the Bhure Lal Committee the status with regard to the utilization of the said land. Bhure Lal Committee may give its report within twelve weeks from today. Within two weeks from today the Delhi Development Authority and the Delhi Administration will file affidavits with Bhure Lal Committee indicating the land details or the land acquired and which have not been constructed upon or utilized till today'.

This ruling came in response to the application from the Amicus Curiae in the matter of W.P.(C) No.202 of 1995; T.N. Godavarman Thirumulpad v/s UoI & others with regard to large-scale acquisition of land by the Delhi Government which took place in early 60's and 80's for the extension of the capital city and for various other earmarked purposes. It appears that though the Government has utilized some of the acquired land still large tracts of this have remained unutilised and large-scale encroachment has taken place on this land. In view of this the Amicus Curiae has brought the following to the notice of the Hon'ble Supreme Court:

Delhi has been declared as one of the most polluted cities. Pollution level in the city is very high and people suffer from respiratory problems. The main cause is the high density of smoke emitting vehicles on the road. The Hon'ble Court in Writ Petition No. 13029 of 1985 has already taken various measures to control vehicular pollution. There is considerable reduction in the pollution level due to these steps taken, but the same is not satisfactory and the pollution level is much higher in comparison to many other cities of the world.

The alternative way of reducing pollution levels is by increasing the greenery in the city. Plants purify air by giving out oxygen. Increasing the green cover in the city is a viable and an effective way to reduce pollution level without disturbing the commercial and economic structure of the city. Creating forests with high density of tree coverage and thereafter declaring them, as reserve forest is a suitable way of increasing greenery in the city. High-density forest would not only reduce pollution in the city but also have a positive impact on the overall climate of the area viz. rainfall. Trees will also prevent flowing of dust and other pollutants in the air.

• Following recommendations made in its report submitted to the Hon'ble Supreme Court:

• Adequate information is not available with regard to the availability of land for afforestration outside the notified forest area in Delhi. Even as the process of identification of additional areas in other land use categories continues, EPCA would like to recommend that immediate priority is accorded to the management and protection of the Delhi Ridge which forms the bulk of forest land in the Capital region.

A supervisory body in the form of Ridge Management Board was constituted under the direction from the Hon'ble Supreme Court for the overall management of the Ridge. In view of the multiplicity of the ownership of land in the ridge area, EPCA recommends that the Board may be reconstituted as an Authority with statutory powers and jurisdiction under the Environment (Protection) Act having representatives from the concerned agencies and the Delhi Government as Member of the Authority. Since the Ridge is the most important forest tract in the region, the final notification under section 20 of the Indian Forest Act of 1927 must be expedited immediately and its management taken up on a priority basis.

All concerned agencies may adopt innovative and participatory approaches to plantations to ensure high survival rates and improve quality of forest cover. Primary focus should be on earmarking lands for block plantations and afforestration.

• Environmental Impact due to Mines

In the matter of IA No. 1785 in W.P.(C) No.4677 of 1985; M.C. Mehta v/s UOI & others the Hon'ble Supreme Court has given the following direction to the Environment Pollution (Prevention and Control) Authority (EPCA) on September 23, 2002:

"Pursuant to the report dated 9 th August, 2002 of the Environment Pollution (Prevention and Control) Authority for the National Capital Region, counsel for the mine owners have filed particulars as to the mines which they say have not been inspected. Each applicant shall deposit in the Registry of this Court within three days a sum of Rs 10,000 for the expenses and the Bhure Lal committee is requested to carry out the inspection of the areas/mines indicated in the statement filed by Mr Kailash Vasudev, Sr Advocate in Court today, the statement being from pages 1 to 5 and the second concerned mines at serial no 1 to 25. The committee is requested to give a report as soon as possible, preferably within a period of three weeks. It is open to Bhure Lal committee to associate such other organisation or persons as it may deem fit and proper for the purpose of inspection."

This is a follow up direction of the earlier Hon'ble Supreme Court order of July 25, 2002, that had given the following direction to the EPCA:

"Copy of the IA Number 1785 and the affidavit of the state of the Haryana be sent to Bhure Lal Committee who may give a report with regard to the environment in that area. The report may be given preferably after a personal visit to the area in question without any advance notice. The Central Ground Water Board should assist the Bhure Lal Committee in giving its report."

Following the July 25 order, EPCA had made a surprise visit to the area to see the mining sites in the villages of Anangpur, Pali, Mohabtabad and Mangar, which fall within the notified area of 5 km radius from the Delhi border in the Faridabad district. EPCA also visited mining sites that are located outside the notified zone in Kot area. Moreover, consultation was also held with the officials of the Central Ground Water Board (CGWB) and obtained their opinion on this matter.

On the basis of study and visit as well as the report of CGWB, EPCA submitted an interim report on "Haryana Ridge and Aravalli hills: Environmental impact" to the Hon'ble Supreme Court.

As per the Hon'ble Supreme Court Order dated September 23,2003, EPCA further examined the issue and held discussions with the concerned officials from different departments. Inspection was made to 26 Mining sites along with the officials from concerned departments of the Haryana state government and mine owners. The overall assessment of the environmental impact of the mining activities in the area especially its implication for ground water level in the region made the following recommendations :

1. The ban on the mining activities and pumping of groundwater in and from an area up to 5 kms from the Delhi-Haryana border in the Haryana side of the ridge and also in the Aravalli hill must be maintained. 2. Not only further degradation be halted but, all efforts must be made to ensure that the local economy is rejuvenated, with the use of plantations and local water harvesting based opportunities. It is indeed sad to note the plight of people living in these hills who are caught between losing their water dependent livelihood and between losing their only desperate livelihood to break stones in the quarries. It is essential that the Government of Haryana seriously implement programmes to enhance the land-based livelihood of people – agriculture, animal care and forestry. Local people must not be thrown into making false choices, which may secure their present but will destroy their future. Already, all the villages visited by EPCA complained of dire and desperate shortages of drinking water. Women talked about long queues before taps to collect water. Clearly, water resources of the region are critical inputs to development and cannot be wasted and destroyed like this. The state government must come up with strategies to involve local communities in the future development of this region. Under the mining lease, 10 per cent of the royalty is to be given to local villagers.. But there was little evidence in these poor and destitute villages that any effort had been made to share the proceeds with them. 3. The Central Ground Water Board must be consulted urgently about what should be done with the huge standing water in the area. This is a valuable national resource and the Board should be asked if the water is best conserved by covering it to stop evaporation or should it be used for recharge and storage with further water harvesting efforts. 4. The Ministry of Environment and Forests (MOEF) should be asked to extend the notification under the Environment (Protection) Act to the Faridabad part of the Aravalli including the ridge. Currently, the notification is only for Gurgoan district. This notification declaring it an ecologically sensitive area will help to regulate the activities in this region. 5. If adequate planning for water is being done in the large-scale construction activities being undertaken in this area. This aspect is outside the purview of this report but needs to be examined carefully. 6. The Gurgoan-Faridabad road is being proposed as the major bypass for the city of Delhi. The Hon'ble Court will note its directives on the air pollution case in this regard. It has been said to the court in that matter that the government of Haryana is intending to widen the road and bids have even been issued to this effect. Therefore, it is all the more important that the mining activity along the road must not be allowed. The 5 km ban from the border of Delhi will take care of this requirement. 7. The mining area outside the 5 km area must be demarcated and regulated in this context.

COMMON EFFLUENT TREATMENT PLANTS

EPCA earlier inspected all the 14 common effluent treatment plants (CETPs), which are either constructed or under construction and submitted its report to the Ministry of Environment and Forests in January 2002. The issue was again taken up with the Delhi State Industrial Development Corporation (DSIDC). As informed by the DSIDC, the present status in respect of these CETPs is as given in Table 14.1.

Table 14.1 Status of Construction of CETPs S. CETP Site Status of Physical Progress Status of Physical No. As on January 2002 Progress as on September 2002 1 CETP at Wazirpur Construction work has been taken up in CETP has been made Industrial Area October, 1999 with scheduled date of operational and pH being completion as June, 2001. Construction of raised upto 6.0. Additional plant completed and trial run started from arrange-ment is being done 12.10.2001. The treatment scheme consists of for proper dosing of primary treatment only to treat 24 mld of chemicals. Since, chemical wastewater per day. Chemical treatment by dosing has been increased addition of lime, alum, polyelectrolyte and substantially, the sludge chlorine dosing is provided. The treatment generation is also huge but plant is non-operational as chemicals required no site for hazardous waste to be supplied by DSIDC is not available since has been created so far January 2002. During the trial period of 3 which is a limitation to months, of commissioning CETP was not sludge disposal. operated at the desired pH of about 8 to precipitate the metals. It has been observed that effluent was brought upto pH of 4 and thus no proper treatment has been provided. It has been also observed that grit removal is not proper as no mechanical system has been provided and therefore grit has found way upto equalization tank. National Environmental Engineering Research Institute (NEERI) has initially assessed the dosing of lime as 200 mg/l which has gone to 2000 mg/l as on today. Since, the sludge generated is hazardous in nature, it is required to be disposed off at Hazardous Waste disposal site, which does not exist as on today in Delhi. The generation of sludge will be very high due to high quantity of chemical requirement. Work awarded for construction of secondary & tertiary treatment plant. 2 Mangolpuri Construction work has been taken up in Work on pumping station for Industrial Area September 1999 with scheduled date of pumping of effluent for completion as April 2001. Trial run of the plant Phase II is completed and started on 28.11.2001. The plant is designed BOD achieved is less than to treat 2.4 mld of wastewater. At present, 10 mg/l. effluents from Mangolpuri-Phase I is being received to the tune of 50-60 m 3 /hr at the plant. Work on pumping of effluent from Phase II is yet to be completed. The treatment plant consists of primary, secondary and tertiary treatment units. The backwash from the dual media filter and activated carbon filter is presently discharged into the drain alongwith the tertiary treated effluent, thus defying the purpose of providing tertiary level of treatment. Hence, it is necessary to make provision for re- cycling of the backwash to the treatment system. 3 Mayapuri Construction work for primary ETP was taken Work on primary CETP is Industrial Area up in November 1999 and scheduled to be complete and work on completed by June 2001. The construction secondary and tertiary CETP work of CETP is complete and trial run is likely expected to be completed to start by first week of February 2002. The soon. plant is designed to treat 12 mld of wastewater. The arrangement to convey effluent from Mayapuri Industrial Area Phase I exist while work of laying of 2.7 km. conduit to convey effluent from Mayapuri Industrial Area Phase II and electrical connections is in progress, which is expected to be completed by the end of February, 2002. The work order for construction of secondary and tertiary units has been awarded recently and scheduled to be completed within 10 months. 4 Jhilmil Industrial Construction work for primary treatment plant 95% work was complete and Area was taken up in September 2000 and expected to be scheduled to be completed by May 2002. The commissioned soon. plant is designed to treat 16.8 mld of wastewater. 90% work of conveyance of effluent from Friends Colony Industrial area is complete and the excavation work for raw effluent pumping station in Jhilmil Colony Industrial Area is in progress.

Expected to be completed by December 2003 14 Najafgarh Road `Technical Bid' is yet to be opened. Work awarded for Industrial Area construction. Expected to be completed by December, 2003

Sewage Treatment Plants

As per Hon'ble Supreme Court order, river Yamuna has to be cleaned by March 2003. Discussions were held with Delhi Jal Board (DJB) in this regard. DJB made a presentation before the Authority on wastewater management in Delhi and highlighted steps being initiated by them for making Yamuna clean. DJB stated that 650 mgd of water being supplied and about 130 mgd of water is being abstracted from underground by other authorities and public. The total wastewater generation is 650 mgd. Out of this, 400 mgd of sewage is being treated. The treatment capacity at present is 482.4 mgd and 30 mgd is under construction. DJB has projected that by 2007, 950 mgd of water will be supplied and around 780 mgd of wastewater will be generated. Wastewater treatment capacity by year 2007 has been projected to be 785.4 mgd including 40 mgd treatment in CETPs.

DJB informed that it will not be possible to clean Yamuna by March 2003 as directed by the Hon'ble Supreme Court and they have requested that the deadline may be extended to December 2005.

Steps should be taken for rehabilitating the trunk sewers, replacement of internal sewers and trapping of drains for diverting the total flow to the sewage treatment plants. DJB is required to ensure that the capacity created is fully utilized.

DJB is required to lay sewers for conveyance of wastewater for CETPs. DJB informed that revamping of effluent conveyance system in Nangloi, Udyog Nagar, SMA, GT Karnal Road and Jhilmil Industrial Area is likely to be completed by December 31, 2002. In SSI Industrial Area, Badli Industrial Area, Kirti Nagar Industrial Area, Naraina Industrial Area and Friends Colony Industrial Area, conveyance system is expected to complete by March 2003. In rest of the CETP, revamping is already completed.

BIO-MEDICAL WASTE MANAGEMENT

EPCA visited some of the hospitals in Delhi and observed that the biomedical wastes are not being properly treated as required under Bio-medical Waste (Management and Handling) Rules, 1998. The issue was taken up with the Delhi Pollution Control Committee. The present status is as below.

In the first phase, DPCC identified 55 major hospitals which have 100 beds and above for implementation of bio medical waste management rules. Out of these 55 hospitals, 31 have their own incineration at present. In year 2000, many hospitals have installed incinerators but not operated due to various operational problems, and switched over to private operators for centralized services. With the switching over to centralized facilities, the hospitals have improved their services and also able to save cost on maintenance of on-site incinerators.

Three Contractors authorized by DPCC are presently collecting the bio-medical wastes and incinerating the same at common facilities. The facility available at Deendayal Upadhyay Hospital is being utilized by a contractor for incineration, autoclaving and shredding of bio-medical waste collected from other 1280 hospitals, nursing homes and clinics. They have 10 vehicles to collect the bio-medical waste and cater to around 1280 units in Delhi. The other Contractor has facility like incinerator, autoclave and shredder for disposal of bio-medical waste, in Narela Industrial Area. This contractor caters to about 400 units in Delhi. The third Contractor has also been authorized recently by DPCC.

DPCC has also associated 3 NGOs for survey of hospitals for effective implementation of the Bio- Medical Waste Rules and awareness programmes. Recently, on the recommendations of DPCC, Central Pollution Control Board has issued notices under Section 5 of the Environment (Protection) Act, 1984 for violation of the provisions of Bio-Medical Waste Rules by hospitals. DPCC said that sharps disposal management in the hospitals is not proper though most of the hospitals are using needle destroyers for restriction of sharps. Sharp are the most dangerous of all medical wastes and require a proper management policy for its disposal.

BYE-PASSING OF TRUCKS IN TRANSIT

The Hon'ble Supreme Court order dated July 15, 2002 in W.P. (C ) No. 13029/1985 directed that plying of all heavy vehicles through Delhi which do not comply with category II norms should be stopped. Delhi Police and MCD are to ensure compliance of the order. EPCA discussed the issue with the Delhi Police (Traffic). It was informed that Delhi Police has initiated action since 27.7.2002. All the goods vehicles which do not have destination to Delhi are being turned away. Number of vehicles turned away at the border by the Traffic Police is given in Table 14.2. Numbers of goods vehicles entered in Delhi from various borders with toll tax labels issued by MCD, are given in Table 14.3.

Delhi Police said that for strict compliance of the Hon'ble Supreme Court order, Police Force has been posted on each entry point to check the travel document and allowed entry only if destination is Delhi. EPCA suggested following steps as long-term solutions to avoid entry of vehicles not required to off load in Delhi :

• Four corridors may be made for interlinking the major highways to act as a bye pass road to Delhi. The non-destining vehicles can take the route through bye-pass; and • Activity relating to checking of papers for goods carriers may be given to the State Government or Municipal Corporation as the Traffic Police is not trained in such work.

Emissions from Auto Rickshaws

It was brought to the notice of EPCA that some CNG auto rickshaws emit excessive white smoke during operation. EPCA asked the manufacturers to take note of the problem and remedial measures. M/s Bajaj Auto Limited agreed that they also received some complaints regarding this matter. After analyzing the problem, Bajaj Auto Ltd. was of the view that most of the 4-stroke three wheelers supplied in the markets are now one-to two years old and reasons for emission of white smoke is due to excessive consumption of lubricating oil and wear off of cylinder, piston and piston rings. These parts are getting worn due to use of sub standard air filter and its improper fitment, use of reclaimed oil and poor maintenance of vehicles including replacement of filter and oil. CNG fuel and kit have no direct bearing on the smoky air exhaust. Smoke is purely due to higher oil consumption associated with poor maintenance of the vehicles. The manufacturers assured to take steps so that the problem get reduced. It was informed that Bajaj Auto Limited has initiated consumer education programme and training of local mechanics on CNG autos. M/s Shrimankar Car Gas Services informed that they have mostly carried out retrofitment of CNG kits and as such they are providing maintenance of the kit as per warranty conditions. They have not come across the problems as yet.

CNG Dispensing Capacity

While hearing the matter regarding affidavit of Shri Rajeev Sharma on capacity to compress and dispense CNG, the Hon'ble Supreme Court vide its order of February 14, 2003 directed the Environment Pollution (Prevention and Control) Authority (EPCA) to examine the following:

"In view of the affidavit filed by Shri Rajeev Sharma, we deem it fit to get a report from Bhure Lal committee, preferably within two weeks."

The Hon'ble Court would like to be apprised if IGL would be able to `make available' or sell 16.11 lakh kg of gas per day as mandated by the Hon'ble Court irrespective of making the distinction between its capacity to compress and capacity to dispense .

EPCA examined the affidavit filed by Shri Rajeev Sharma Ex. Managing Director, IGL on February 10, 2003. It has further considered the following affidavits filed in response to the show cause notice served by the Hon'ble Court on September 9, 2002.

Affidavits filed by Shir A K De, Managing Director, IGL (dated October 23, 2002), Shri P S Bhargava (February 13, 2003) and Shri L Lobo (February 11, 2003) of IGL. Both Shri P S Bhargava and Shri L Lobo have stated in their respective affidavits "explanation submitted by Mr De before this Honb'le Court are adopted by me." (Hereafter these three affidavits are referred to as IGL affidavit).

EPCA has analysed the sequence of events emerging from the April 5, 2002 order and the affidavits filed by IGL, thereafter, to examine if the affidavits from the IGL officials in response to the show cause notice have adequately addressed the key concern of the court -- if IGL would be able to `make available' the Court mandated 16.11 lakh kg of CNG by June 30, 2002, to meet the projected demand in the transport sector in the city. EPCA prepared a report titled "IGL show cause notice : Comments on affidavit filed by Rajeev Sharma and others" which includes following observations and recommendations:

1. On scrutiny of the affidavits of Shri Rajeev Sharma and IGL, it is clear that there is no disagreement or difference between the two in their various contentions, on the terms, "compression capacity" and "dispensing capacity": a. The term compression capacity means the capacity of the compressor installed to compress gas; b. The capacity/capability to dispense gas, which is dependent on the compressors as well as the related infrastructure like dispensers, location of stations etc needed to dispense gas efficiently, without long queues, and; c. In addition the actual offtake of gas, which is dependent on the number and sizes of vehicles coming for refuelling, in other words, the actual sales. 2. The actual sales/offtake of gas is a critical determinant in the price fixation by the IGL management. In its justification for the increase in price from Rs 13.11 to Rs 16.83 per kg in April 2002, IGL had estimated that it would sell between 6-7 lakh kg of gas in 2003-04 in its realistic and optimistic scenarios. EPCA has found that in February 2003, the actual sales of gas is 7.17 lakh kg per day, which is higher than what had been estimated by IGL to compute its annual sales. IGL is also dispensing 61 per cent of its installed capacity. 3. Based on the above, EPCA is now of the view that the decision in April 2002 of IGL to raise the CNG prices cannot be justified, as it assumed a projected sale estimate and capacity utilisation, which is not borne out of the above scrutinised facts. 4. It must be noted that CNG is a court-mandated market that has established the baseline demand of gas for the transport sector in Delhi. IGL will at the minimum sell the amount of gas mandated under the various orders of the court to a fixed number of commercial transport vehicles in the city. A potential demand exists beyond this minimum sale and IGL will have to work towards realising this market potential with aggressive marketing strategy to remain cost- effective. Otherwise, there is a likelihood of the Capital costs of expansion of CNG infrastructure being passed on to the existing consumer, especially commercial transport. Capital infrastructure will only lead to an increased burden on the consumers. 5. The vast infrastructure for CNG delivery has been created not only at enormous financial cost but also at consistent Court, public and government endeavours. This reality has to be recognised by IGL. 6. EPCA is of the view that instead of focusing on the narrow technical distinction between dispensing capacity and compression capacity to justify a conservative projection of sales and demand, it is more important to frame appropriate policies and strategies to increase CNG sales. 7. CNG has been introduced in this city to control particulate pollution. It is therefore, in the interest of public health to encourage large-scale conversion of vehicles to CNG. But the countervailing pressures of the CNG price hike last year, coupled with a tacit policy to actively discourage conversion of private cars to CNG due to poor availability of gas, the long queues at the filling stations has dampened demand for CNG in the city, negating some of the efforts made as cited above. Central and the state governments be directed to submit a phase-in plan to run more vehicles on CNG and actively encourage private vehicles to run on CNG as well. To facilitate this process, appropriate fiscal and economic incentive policy should be designed. 8. The price hike was possible only because of the lack of a regulatory framework for promoting CNG as an autofuel. This bears out the importance of a policy that would safeguard against similar arbitrary decisions to increase prices in the future, which could jeopardise the CNG programme in Delhi.

To safeguard against any further arbitrary price based purely on commercial objectives of the companies supplying CNG, the government must be directed to set up a regulatory and a fiscal mechanism to promote CNG and other environmentally acceptable fuels. EPCA has noted with concern that with deregulation and price reforms underway, there is little elaboration of the issue of CNG as an auto-fuel in official policies to make CNG competitive vis a vis its competing fuels like diesel and petrol. EPCA had earlier noted in its pricing report that CNG would directly compete diesel more than petrol. As a result, the taxation policy should be designed in a manner that an appropriate and effective price differential is maintained with diesel. The review of the fuel taxation policies round the world shows that "favourable" taxation is an important instrument to maintain the price differential to encourage environmentally acceptable fuels. To underscore this point EPCA would like to reiterate this recommendation already made in the pricing report with regards to the fiscal policy on CNG.

IMPLEMENTATION OF MALE'S DECLARATION ON CONTROL & PREVENTION OF AIR POLLUTION

Air pollution is an emerging environmental issue in Asia as it is in other parts of the world. To cope up with the issue of Transboundary Air Pollution in South Asia, the Male's Declaration was adopted by Ministers of the Environment at the Seventh Meeting of the Governing Council of South Asia Cooperative Environment Programme (SACEP), held on August 22, 1998 in Male, Republic of Maldives.

The Male's Declaration stated the need for the countries to carry forward or initiate studies and programme on Air Pollution in each country of South Asia. The Phase – I of the Male Declaration started in 1999 saw the establishment of the network of organisations to implement the Declaration and compilation of Baseline information on Air Quality Monitoring and Management in the participating caountries.

The Phase – II of the programme commenced in 2002 and the objective of this phase is to put in place the expertise equipment and information, needed for the quantitative monitoring, analysis and policy recommendations for eventual prevention/control of air pollution. The specific objectives of this phase are:

• Expanding the existing network; • Establishing/strengthening monitoring facilities; and • Study the transboundary effects of air pollution.

As a part of the Implementation of Male Declaration, a stakeholder meeting was held in New Delhi on September 24, 2002. Over 50 participants from all sectors as well as implementing agencies of Male Declaration participated in the meeting. Central Pollution Control Board, Delhi and the Ministry of Environment & Forests, SACEP, SEI and UNEP/RRC-AP jointly organised the meeting. Recommendations were derived from the forum for future implementation of the Male Declaration. A National Advisory Committee has been constituted under the Male Declaration. The Committee envisages members from State Pollution Control Boards, Research Organisations, NGOs etc.

MANAGEMENT OF MUNICIPAL SOLID WASTE (MSW) To motivate local bodies for undertaking implementation of Municipal Solid Wastes (Management and Handling) Rules, 2000, CPCB has taken up several initiatives. The actions taken include; Persuasion/ interaction with State Boards and local bodies, strengthening of infrastructure of State Boards, undertaking field studies relating to various aspects of waste management and drawing up action plan for management of solid waste in cities and towns.

Feed Back from States and Union Territories (UTs)

The feed-back received from the local bodies and SPCBs indicates the following status of municipal waste.

• Majority of the local bodies are aware of the Rules and their responsibilities; • SPCBs and PCCs have constituted Committees to deal with issues relating to; issuance of authorizations, identification of landfill sites, management of accidents and Technology Appraisal for the assistance of local bodies; • State Governments are in the process of evolving State level policies to set up waste processing facilities; and, • CPCB jointly with SPCBs/PCCs organized interactive meets with local bodies includes Chhatisgarh, Meghalaya, Chandigarh, Orissa, Himachal Pradesh, Andhra Pradesh, Uttar Pradesh, Gujarat, Tripura, Madhya Pradesh, Punjab.

Capability Development

Based on proposal of CPCB, the Ministry of Environment and Forests (MoEF) has provided financial support to SPCBs/PCCs to strengthen infrastructure facilities for enabling them to implement MSW Rules. Financial assistance has been provided to 33 SPCBs/PCCs. SPCBs/PCCs have set up waste management cells for interaction with the local bodies and for field surveys/ investigations.

Action Plan for Municipal Waste

Based on the quantum of solid waste generation in cities and towns, a strategy has been formulated for implementation of the Rules. According to the size of the town (population and quantity of solid waste generation) action plan has been suggested.

Demonstration Facility

It is proposed to set up at least one demonstration facility in each State/UT. Such facility would cover providing financial support to the candidate local body on 70:30 (subsequently agreed for 50:50) funding pattern. Under this scheme, all aspects of the Rules will be covered for demonstration purpose and other local bodies could replicate them in a phased manner.

BIO-MEDICAL WASTE MANAGEMENT

Bio-Medical Waste Management

1. Under the Project "Strengthening of Hospital Waste Management Programme", a WHO funded activity, two hospitals have been developed as model for demonstration of segregation system of bio-medical waste as per the Bio-medical Waste Rules, 1998. The hospitals that have been developed are Govt. Medical College, Jammu and Vivekanand Polyclinic, Ramakrishna Mission Sevashram, Lucknow. A demonstration program was also conducted at each of these hospitals to demonstrate and educate various stakeholders on July 29, 2002 and September 21-22, 2002 at Jammu and Vivekanand Polyclinic respectively. 2. In compliance to the Hon'ble High Court, Allahabad's order, CPCB carried out inspection of 33 hospitals/common treatment facility in Uttar Pradesh during March 14, 2002 to April 04, 2002. Stack emission monitoring of 6 incinerators was also carried out and the report was submitted to the Hon'ble High Court. 3. CPCB also assisted Delhi Pollution Control Committee in carrying out inspection of hospitals in Delhi for issuing authorisation to the hospitals under the provision of the Bio-medical Waste Rules. 4. Healthcare facilities being a health service industry, issuing stringent action to defaulters hospitals as stipulated in the Environment (Protection) Act, 1986 may effect the social service offered by these healthcare facilities. At the same time, it is duty of all the healthcare facilities to implement the provisions of the Bio-medical Waste Rules. Putting equal importance to both views, CPCB approached MoEF to include a provision of compounding of offences through amendment in Bio-medical Waste Rules, 1998. 5. Various treatment technologies are coming up as options for treatment of bio-medical wastes. Few such technologies were evaluated by CPCB and a provisional approval has been given to "Logmed" technology. The "Logmed" technology is a thermal dis-infection process using heat transfer oil. Moreover, two other technologies i.e., Metal Sharp Manager and Demolizer System are under process of evaluation. 6. For effective implementation of the BMW Rules, CPCB has been continuously following up the SPCBs/PCCs to initiate action under the Environment (Protection) Act, 1986 against the defaulter hospitals so as to make it clear that the Rules are meant for enforcement.

With reference to the above letters, a number of SPCBs/PCCs have issued show-cause notices to the defaulter hospitals.

7. To catch hold the defaulters, CPCB issued show cause notices under Section 5 of Environment (Protection) Act, 1986 to 18 defaulter hospitals in Delhi (5), Uttar Pradesh (3), Rajasthan (5), MP(4) and Chhatisgarh (1). The notices were issued upon recent vesting of required powers by the Govt. of India to CPCB. 8. CPCB is regularly following up the SPCBs to submit the information on bio-medical waste management as per the provision of the Bio-medical Waste Rules, 1998. Based on the information received from SPCBs/PCCs, a status report on implementation of Bio-medical Waste Rules has been prepared. 9. The status of Common Bio-medical Waste Treatment Facilities has also been prepared by CPCB.

CPCB also compiles the status of implementation of the BMW Rules in the country. As per information submitted by SPCB/PCC, out of 5,05,647 kg of bio-medical waste generated per day in the country, 1,37,357 kg of waste is treated. There are total 438 incinerators and 216 other treatment equipments in the country.

10. CPCB conducted a two days workshop in association with Andhra Pradesh Pollution Control Board at Hyderabad during February 25-26, 2003. The objective of the workshop was to develop guidelines for establishing Common Bio-medical Waste Treatment Facilities. The participants were from SPCBs, common treatment facility operators and major hospitals. As the outcome of the workshop, CPCB has prepared draft Guidelines for Common Bio-medical Waste Treatment Facility. The same is under process of finalization. 11. CPCB has also prepared draft Guidelines for design & construction of bio-medical waste incinerator, which is based upon the experience of CPCB and in-consultation with incinerator manufactures. The final document will be helpful to check the proliferation of poor quality of incinerator. 12. A documentary filmmaking project has been awarded to Govt. Medical College, Jammu on Bio- medical Waste Management to demonstrate the best practices of segregation, transportation and treatment technologies.

To generate awareness on Bio-medical waste management, CPCB supported awareness cum training programme for staff of Gujarat Pollution Control Board on monitoring and implementation of Bio-medical Waste (Management & Handling) Rules, 1998.

Bio-Medical Waste Management in North-Zone

The hospitals and bio medical facilities meant to ensure better health have unfortunately become a potential health risk due to mismanagement of the infectious waste. Realizing this, Ministry of Environment and Forests, Govt. of India notified the rules, called Bio-Medical Waste (Management and Handling) Rules, 1998, which has come into force since July 27,1998.

Bio-medical waste from hospitals, nursing home and other health centers composed of variety of wastes like hypodermic needles, scalpels blades, surgical cottons, gloves, bandages, clothes, discarded medicine, blood and body fluids, human tissues and organs, radio-active substances and chemicals etc. This area of waste management is grossly neglected.

The situation of bio medical waste management in entire north zone is pathetic. In Punjab a common facility has been developed to cater to the cities of Ludhiana, Jallandhur, Patiala and Amritsar. In Haryana clearance have been given for a common facilities, which however is yet to be developed. In H.P out of total 10 incinerators installed one each at Shimla and Paonta Sahib is also working as common incinerators for the hospitals in that region. In U.P. only 5 common facilities have been so far developed and few more are in process.

The common facilities at Ludhiana in Punjab and in Kanpur are comprehensive as stipulated in the Act but at other places common facilities are mainly having incinerators as treatment facility. Segregation is the most neglected aspect and progress on this part paint dismal picture.

In order to effectively implement the bio-medical waste management rules a comprehensive survey and monitoring was undertaken at various hospitals in Uttar Pradesh. In all thirty-three medical establishments were inspected and monitoring conducted for incinerators which are installed as per norms.

Status of incinerators in individual medical establishments and common facilities are as below:

Single chamber incinerators : 10

Double chambered incinerators with

Inadequate stack height : 07

Incinerators installed but not commissioned : 04

Bhatti type facilities : 04

Observations

• The segregation of waste in almost all hospitals is not satisfactory. • Colour coding for various categories of waste is not followed. • The storage of bio-medical waste is not in isolated area and proper hygiene is not maintained. • Personal protective equipment and accessories are not provided. • Most of the hospitals do not have proper waste treatment and disposal facilities. In the cities where common treatment facilities have come up, many medical establishments are yet to join the common facility. • Emission monitoring of five incinerators indicated that they do not meet the emission norms. • Most of the incinerators are not properly operated and maintained, resulting in poor performance. • Sometimes plastics are also incinerated leading to possible emission of harmful gases. • Several hospitals have not applied to State Pollution Control Board for authorization under the rules. • General awareness among the hospital staff regarding bio-medical waste is lacking.

Recommendations and Follow-up

• All health care facilities generating Bio-medical waste shall strictly ensure segregation, colour coding and other provisions of Bio-medical waste (Management & Handling) rules, 1998 and amendments thereof. • Hospitals should apply to state Pollution Control Board for authorization to handle and treat the waste. • Incinerators, which do not conform the design & emission norms as per rules, must be modified and air pollution control system may be retrofitted to minimize the emission level. • The operator should ensure proper O&M of incinerator through attainment of required temperature in both the chambers, regular operation of the incinerator, proper maintenance of the logbook and storage of the waste in isolated area, plastic incineration should not be undertaken. • Proper training and personal safety equipment / accessories should be provided to waste handling staff. • Records of waste generation, treatment and disposal should be maintained by the hospital. • Steps should be taken to set up common bio waste treatment facility in each city/town with strict monitoring of these facilities by regulatory agency and individual facilities should be discouraged. This is on account of the fact that improper operation may lead to increase in air pollution problem. Better siting, management and monitoring is possible in common facilities only. • The amounts changeable for the waste in most of the common facilities are for below the minimum O&M cost. This needs to be rationalized else it may lead to non-operation of facilities. • Various regulatory agencies, Hospitals, Medical Association & Municipal Corporation should work together for proper management of Bio-medical waste in the cities/towns.

Action has been initiated against 3 medical colleges (KGMC, Lucknow, GSVM, Kanpur and JLN Medical College, Aligarh) for having bed capacities more than 1000 but do not manage the bio-medical waste as per rules. Steps are also being taken against other hospitals, which do not follow the rules and operate the incinerators, to meet the emission norms.

A project on ‘Model Segregation Practices' was also completed in Vivekanand Polyclinic, Lucknow and in Govt. Medical College Jammu for practical demonstration of segregation of bio-medical waste in bio- medical waste management.

Bio-medical Waste Management in Himachal Pradesh

The Himachal Pradesh State Environment Protection & Pollution Control Board has conducted study in major hospitals. It has been decided to set up the demonstration model named Dr. Rajinder Prasad Govt. Medical college & Hospital at Dharmshala with following objectives;

• Assessment of existing waste management practices. • Classification, quantification & characterization of waste streams.

The hospital is having 258 beds and equipped with all the medical facilities like Emergency, Maternity, Gynecology & Child wards, ENT Deptt., Surgical, Orthopaediatric, OPD, Blood Bank and other radiological facilities. The quantity of bio-medical waste generation is estimated to be 100 kg/day (Fig 14.1). Besides this 30 lit./day of liquid waste is being generated from washing of laboratories and kitchen. As per the data, per bed waste generation is estimated as 380 gm/day. Major contribution is from disposable, waste sharp and soiled waste. The following methods are adopted in the hospital;

• Provisions of needle destroyer in some wards. Discarded needles and syringes are rarely destroyed and disinfected. • The transportation of waste by hand lifting in the bins or gunny bags. • Final treatment of waste by incineration.

Lack of awareness amongst the hospital staff including doctors towards the segregation of infectious waste is one of the main reasons for mismanagement of Bio-medical waste in the hospital. Mass awareness programme for management of bio-medical waste should be carried out at regular interval.

HAZARDOUS WASTE MANAGEMENT

Identification of Hazardous Waste Streams, their Characterisation and Waste Minimisation Options in various Industrial Sectors.

CPCB has undertaken the project on Identification of Hazardous Wastes in different industrial sectors/processes. The selected sectors for such study are Petrochemical, Pesticides, Dye & Dye Intermediates and Bulk Drugs & Pharmaceutical. The objective of the study is to identify various hazardous waste streams generated from unit operations during production, estimation of hazardous waste generation per tonne of product, characterisation of hazardous waste streams and possible options of waste reduction/recovery and recycling. The study on Petrochemical sector has already been reported. During the year 2002-2003, a study for Dyes & Dye Intermediate sector has been completed. The findings, in terms of product-wise hazardous waste streams identified in Dyes & Dye intermediate sector are given in Table 1 and quantity of hazardous waste generation and waste quantity suitable for land disposable incineration are given in Fig 14.2. An attempt has also been made to suggest waste minimisation and disposal options. The product-wise waste minimisation and disposal options are given in Table 14.4 to 14.6.

Criteria for Disposal of Hazardous Waste and Leachate Standards for Secured Landfill Facilities

According to Schedule 4 of the Hazardous Waste (Management & Handling) Rules, 1989, as amended in 2000, one of the responsibility of CPCB is to recommend standards for treatment & disposal of waste and leachate. In view of this, CPCB has conducted a study on the detail "Criteria for Disposal of Hazardous Waste, Leachate Standards for Secured Landfill Facilities and Guidelines for Leachate Collection, Treatment & its Safe Disposal".

The criteria developed for hazardous waste disposal and the guidelines for leachate collection, treatment & disposal options including leachate standards were discussed and finalised by the Sub Committee constituted by CPCB. The hazardous waste disposal criteria and the leachate standards approved by the Board are presented in Table 14.7.

Environmental Management in Caustic Soda Industry

In India, caustic soda is mainly produced by mercury cell and membrane cell processes. At present, about 70% of capacity utilization of caustic soda is achieved by membrane cell process and remaining by mercury cell process. Presently, there are 10 plants fully based on mercury cell process, 6 plants are partially based on mercury cell process, and 19 plants are fully based on membrane cell technology.

Though the existing caustic soda plants are complying with the liquid effluent and gaseous emission standards, it is observed that the consumption of mercury and its release through products, brine sludges and cell house ventilation gas are high. Therefore, in order to minimize release of mercury through various sources, various measures are proposed and the same were discussed with the industry representatives and Alkali Manufacturers Association in a National Seminar on "Corporate Responsibility for Environmental Protection (CREP)" held in March 2003. Various actions agreed by the industry in the said CREP for minimisation of mercury pollution from caustic soda industry, are as follow:

• Complete recycling of mercury bearing effluent by December 2003 • Installation of continuous on-line mercury analyzer by June 2003 • Treatment of cell-room ventilation gas – limit for mercury not to exceed 1 gm/t of product by December 2005 • De-mercerization of caustic soda & limit for mercury in caustic soda at 0.1 gm/t of product by December 2004 • Reduction of mercury in H 2 gas at 0.5 gm/t by December 2004 • Installation of common full-fledged salt washery unit at source by December 2003 • Capping of existing completed disposal sites by June 2004 (Action plan to be submitted by June 2003) • Installation of mercury distillation units by June 2003 • Brine sludge treatment and water leachable mercury content in brine mud at < 0.1 mg/l before disposal in Secured Landfill • Reduction of mercury consumption at < 50 gm/t of product by December 2005. • Total mercury release to environment at < 2.0 gm/t of product by December 2005. • The mercury cell plants will switch over to membrane cell technology in a time bound manner for which action plan will be prepared by respective plants within six months • Industry to submit action plan covering the pollutional and safety aspects for Cl 2 handling to prevent any accident / release of Cl 2 , within three months.

Inventory of Hazardous Waste Management Facilities in Maharastra

The CPCB western zonal office had taken up project on inventory of hazardous waste management facilities in Maharastra. Considering the large area of extent, the detailed questionnaire was prepared to collect the dry data through the Regional and Sub-regional Offices of Maharastra Pollution Control Board. In addition, field visits were also carried out to collect the information on general status of hazardous waste management practices adopted by the industries as well as in industrial estates. As such there was no common secured landfill site exists in the State. However, in recent past the MIDC has developed one site at Taloja. But still the hazardous waste is either being stored by the industries in their own premises or dumped in a haphazard manner in industrial estates. There are six other potential sites identified by the MIDC and they are under different stages of development.

Inventorisation of Hazardous Waste Generation in Orissa:

Orissa State Pollution Control Board in consultation with CPCB has under taken the study on "Inventorisation of Hazardous Waste Generation in Orissa State" in the light of Hazardous Waste (Management & Handling) Amendment Rules, 2000. Main aim of the study is to 1) identify hazardous waste generating units, 2) to categorise waste as per the amended rules, 3) to quantify hazardous waste generation and 4) to assess the present method of collection, storage, treatment and disposal of hazardous waste in the State of Orissa. The distribution of small, medium and large scale industries is given in Figure 14.3.

The sector-wise quantification of hazardous waste generation are given in Fig 14.4.

SPATIAL ENVIRONMENTAL PLANNING (ZONING ATLAS PROJECT)

State-wise Mapping of Environmentally Sensitive Zones and Industrial Sites

The activity on Mapping of Environmentally Sensitive Zones and Industrial Sites aims at presenting information on environmentally sensitive zones, viz. national parks, reserved forests, protected forests etc. and industrial sites, state-wise, in the form of maps (1:1 M scale).

So far, the work has been completed for the 18 States of Bihar, Meghalaya, Kerala, Goa, Andhra Pradesh, Orissa, Gujarat, Karnataka, Assam, Manipur, Maharashtra, Jammu & Kashmir, Chhattisgarh, Madhya Pradesh, Uttar Pradesh, Uttaranchal West Bengal and Tamil Nadu and the work is n progress for Rajasthan and Punjab.

Zoning Atlas for Siting of Industries The District-wise Zoning Atlas for Siting of Industries, zones and classifies the environment in a District and presents the pollution receiving potential of various sites/zones in the District and the possible alternate sites for industries, through easy-to-read maps (1:2,50,000 scale). These studies have been taken up to help overcome the existing problems of improper siting of industries and industrial estates and incompatible land use, lack of proper treatment and disposal facilities for wastes and to minimise risks on the surrounding environment. The studies help in identifying areas to be avoided for siting of industries and to find out alternate sites/zones that may be considered for siting of industries. These are helpful to the industrial entrepreneur in selecting sites that are environmentally sound, the regulatory authorities in issuing environmental clearances, the Government in taking policy decisions on industrial siting and the public in knowing the type of industrial development in advance. The studies, thus, help decision making on site clearance transparent, faster and reliable.

Work for 84 Districts was completed earlier. Work is in progress for 58 Districts in the current year covering twenty-one States and one Union Territory including Andhra Pradesh, Assam, Bihar, Chhattisgarh, Gujarat, Himachal Pradesh, Jammu & Kashmir, Karnataka, Kerala, Madhya Pradesh, Manipur, Maharashtra, Meghalaya, Orissa, Punjab, Rajasthan, Tamilnadu, Tripura, Uttar Pradesh, West Bengal, Goa and Union Territory of Pondicherry.

Industrial Estate Planning

In continuation of the Zoning Atlas studies, the Industrial Estate Planning studies are taken up at a micro-level (1:50,000 and lower) to identify the sites for industrial estates, to suggest waste disposal points and to provide suggestions on control of surrounding land uses.

The studies are helpful to the industrial estate developers and the industries departments in properly locating the industrial estates and in planning the needed pollution abatement infrastructure and disposal facilities. So far, the studies have been completed for twelve sites as below:

State District Andhra Pradesh East Godavari Bihar East Singhbhum Gujarat Amreli Himachal Pradesh Solan Kerala Palakkad Madhya Pradesh Sagar Meghalaya Ri-Bhoi Orissa Undivided Cuttack Punjab Ludhiana Tripura North Tripura Uttar Pradesh Bulandshahr West Bengal Bankura

In respect of the sites of Andhra Pradesh, Bihar, Punjab, Uttar Pradesh and Meghalaya, the Ministry of Environment & Forests (MoEF) has cleared the reports in-principle and sent to the respective State Pollution Control Boards for follow-up with the concerned departments for identifying the exact location of the sites, pollution abatement infrastructure etc.

In addition, the reports are in final stages for the following sites:

The studies are in progress in respect of the following:

State District Karnataka Mysore Manipur Imphal Rajasthan Alwar (Tijara Sub-division)

The studies are in progress in respect of the following:

State Site/District Andhra Pradesh Hyderabad-Vijayawada Corridor – Site-1 Andhra Pradesh Hyderabad-Vijayawada Corridor – Site-2 Gujarat Padra, Vadodara District Himachal Pradesh Poanta Sahib Orissa Raygadh Meghalaya Smit Nongkrem Meghalaya Umryndang

In addition, the reports are in final stages for four sites and studies are in progress for 13 sites. Also, CPCB submitted a proposal to the Ministry (MoEF) to make environmental clearance mandatory for setting p industrial estates, which is under consideration.

It is also contemplated to develop Eco-industrial Estates in the country in order to ensure proper siting of industrial estates, planning of the pollution abatement infrastructure and regulating development around these sites. Preparatory work in this regard has commenced.

Regional Planning Studies

In continuation of the District-wise Zoning Atlas studies, pilot studies on Regional Planning were taken up for Jalpaiguri District of West Bengal and the entire State of Tripura . These Studies are for demonstrating the utility of environmental planning tools for achieving sustainable development of the District/Region/State harmonising social, economic and environmental needs through appropriate planning and management of land and its resources. The studies for Jalpaiguri and Tripura have been completed and the reports are under finalisation.

Environmental Management Plans for Urban Areas

The activity on Environmental Management Plans (EMP) for Urban Areas is targeted to provide planning solutions for the urban areas where in the problems are becoming complex and the environmental risks are increasing. The overall objective of the study is to identify measures for improvement of environmental quality in cities and ensure that the environmental risks from various developmental activities are minimized and the development/siting of further activities take place in an environmentally sound manner.

Subsequent to the Kanpur study, the EMP study on Agra was taken up by CPCB in 2000, which has been completed, and priority projects identified. Preparation of similar EMPs has been completed for Indore, TTZ, Bhubaneshwar, and Chennai.

Environmental Management Plan for Mining Areas

Similar to the preparation of environmental management plans taken up for urban areas, studies were also taken up for mining areas including Korba coal mining area (Chhattisgarh), Dhanbad coal mining area (Bihar) and Satna limestone belt (Madhya Pradesh). The studies for Korba and Satna are completed and the reports are under finalization.

Environmental Management Plans for Tourism Areas Similar to the preparation of environmental management plans taken up for urban areas, studies were also taken up for tourism areas including Bakel Fort (Kerala) and Macleodganj (Himachal Pradesh). The report of Macleodganj is complete and under finalization.

Environmental Management Plan for Environmentally Fragile Areas

Similar to the preparation of environmental management plans taken up for urban areas, studies were taken up for Panchmarhi Biosphere Reserve located in Madhya Pradesh, which is an environmentally fragile area. The study has been completed and the report is under finalisation. A study on Environmental Information System of Amarkantak Biosphere Reserve has been taken up to provide information on environmentally fragile areas. The study is in advance stage of completion.

Mapping of Polluting Industries

This pilot study has been taken up with an objective to create an inventory of industries in the State of West Bengal in GIS environment to facilitate decision-making on prevention and control of pollution in industries. The study is in advance stage of completion.

Ecocity Programme

Under the 10th plan, the Ecocities programme is being extended to small and medium towns in the country. The programme is aimed at bringing in verifiable environmental improvement through execution of identified projects. The work has commenced for launching the project in Mathura (Uttar Pradesh), Ujjain (Madhya Pradesh), Puri (Orissa), Vapi (Gujrat), Thanjavour (Tamil Nadu), Rishikesh (Uttaranchal), Tirupati (Andhra Pradesh), Shillong (Meghalaya), Kottayam (Kerala) and Vrindavan (Uttar Pradesh).

Taj Eco City project Study

The Taj Eco City covers an area of 30 sq. km in the periphery of the Taj. The primary objective of the study being to improve the overall living conditions in the city. This would be achieved by developing a mechanism to trigger a resource utility pattern for sustainable urban development by introducing aesthetically appeasing elements with strong economic potential into the urban micro region. The results will thus, be visible and can be easily replicated to other parts of the city as well as to other urban areas. GTZ is consultation with CPCB prepared a pre-feasibility report for the designing of the Taj Eco City. The study was undertaken in three parts:

• A brief presentation on the present situation • The development of the Master Plan • The assessment of the proposals

The study stresses on the fact that tourism should never dominate the economic structure of the city, but should remain an important part of it. In Agra though tourism is an important part of the economy, in addition the city does support a large number of trade and commercial activities along with industries, which need to be given due importance in the planning process.

Taj Trapezium Zone

The 10,400 sq km region covered under the Taj Trapezium Zone has been categorised as a sensitive zone as early as 1983 due to the existence of as many as four world Heritage Sites. However, no comprehensive study had ever been done for the region. This is the first study of its kind, which aimed at compiling baseline information for this spatial unit in a uniform format. It focuses on identifying the potential of this region, spanning over six districts (five in Uttar Pradesh and one in Rajasthan).

Some important urban centres in the States come under the Taj Trapezium Zone, namely Agra, Firozabad, Mathura, Bharatpur, Jalesar and Hathras. These are the primary growth centres of the region, influencing not only the regional economy but also the environment. The continuing uncontrolled development has had detrimental environmental effects, creating a mandatory situation, calling for a scientific enquiry for the identification of alternative economic pathways that would give sustainable solutions negating adverse environmental impacts. The sensitive nature of the region calls for non-polluting economic activities. The study tries to focus on alternative economy enhancing activities. The rich cultural and natural heritages have been recognised by the study as instruments for leveraging the regional economy through tourism. The region also boasts of one of the most fertile lands in the country. Agriculture thus is a dominant income generator in the region, the study gives broad solutions for enhancing the agricultural productivity in the region.

The study is a comprehensive analysis not only of the status of the physical infrastructure but also the natural constraints such as the semi-arid nature of the area and the arising problems, giving broad solutions.

Urban Environmental Information System

The programme urban environmental information system (Urb-Envis) is targeted to provide information in the form of a local environmental report to be prepared by the Municipality on the status of socio- economics, development and environment. The main purpose of the Urb-Envis is to:

• sensitize politicians and administration on local environmental problems and improvements needed • inform people of the local environmental situation and improvements achieved from year to year • help identify key environmental issues • undertake detailed studies such as preparation of Environmental Management Plans and other environmental assessments and prepare Action Plans for implementation of measures • help the politicians/elected members project their good deeds towards environmental improvement • bring in internal competition among the different wards of the Municipality and among various cities/towns for improving environment.

The programme is expected to bring awareness and develop local dynamics and demands for environmental improvement. Under the programme, a bi-annual public report will be brought out detailing the status of environment and also the detailed information will be placed on the website which will be updated and maintained by the participating municipalities. The municipalities will be locally supported by state pollution control boards and centrally coordinated by CPCB.

The programme will be extended in the 1 st Phase to the following volunteering Municipalities:

1. Indore Municipal Corporation 2. Bhubaneshwar Municipal Corporation 3. Municipal Corporation of Chennai 4. Agartala Municipal Council 5. Guntur Municipal Corporation 6. Agra Nagar Nigam 7. Kanpur Nagar Nigam 8. Kottayam Municipal Council 9. Patna Municipal Corporation

A memorandum of understanding (MoU) has been entered into with the municipalities, concerned State Pollution Control Boards and CPCB.

Urban ENVIS at Agra

The Central Pollution Control Board has initiated the Urban-ENVIS report of one of its Project areas: Agra. The preliminary data collection from routine monitoring and surveys has been completed and the technical know-how on the required work has been provided to UPPCB and the Agra Nagar Nigam to further carry out the work. The Agra Nagar Nigam in turn is in the process of identifying a key coordinator as well as forming the core group incharge for preparing the report. The regular follow-ups being made keeping its role as an advisory facilitator, responsible for the planning, development, coordination and overseeing the execution.

Human Resource Development A comprehensive human resource development programme has been undertaken with the support of InWEnt, Germany (on behalf of the Federal Ministry for Economic Cooperation and Development, Germany) for catering to various target groups relevant to spatial environmental planning in India. A MoU was executed with various training institutions in India for undertaking the identified training programs and spatial environmental planning network (SEP-Net) has been formed with these institutions for execution of the programme.

The significant achievements of the HRD Programme are given below:

1. Teams in the SPCBs of Bihar, HP, Gujarat, Orissa, Kerala, Tamil Nadu, West Bengal, EPTRI fully trained on GIS 2. Several awareness programmes and workshops were conducted. 3. Overseas training in Germany for two teams from CPCB/SPCBs/MoEF/training institutions/development authority etc. were conducted. The teams included officers working at middle as well as senior levels. 4. SEP-Net was formed with 9 training institutions for conduct of courses. A logo for the HRDP and a brochure were developed. A website on the programme ( www.cpcb-hrdp.com ) was launched. 5. MoU was signed by CPCB with all the training institutions. 1 6. 3 training programmes has so far been conducted with SEP-Net.

1. Quality Assurance manual has been developed with the help of CDG's experts. 2. The course evaluation methods were worked out and tested.

Infrastructure Strengthening

Several actions were taken to strengthen the infrastructure at CPCB and in the state pollution control boards. Efforts were put in to create exemplary working environment and latest equipment to produce reliable outputs. Major achievements in infrastructure strengthening are given below:

1. The Zoning Atlas Unit at CPCB was upgraded to a Centre for Spatial Environmental Planning in December 2000. The Centre has full-fledged GIS facilities and infrastructure. It is also now proposed to construct a new building at the premises of CPCB. 2. A model Centre was constructed at Himachal Pradesh State Environmental Protection and Pollution control Board with GTZ support based on CPCB design inputs. A similar centre was also constructed at Maharashtra Pollution Control Board. Designs for Centres also provided by CPCB to Orissa and Bihar State Pollution Control Boards. 3. High end PC, Printer, colour printer cum copier, UPS, CD writer, LCD Projector, Internet connection, digitiser, plotter and GIS softwares (Arc Info, Arc View) were installed in different State Pollution Control Boards and executing agencies involved in the project.

TECHNICAL AND FINANCIAL ASSISTANCE FOR INSTALLATION OF DEMONSTRATIVE ROOFTOP RAINWATER HARVESTING (RWH) SYSTEMS IN SPCBS

With a view to demonstrate the ease of practicing rooftop rainwater harvesting for management of water resources, the Central Board has initiated a scheme for financing up to Rs.2.50 lakh for State Pollution Control Boards/ Pollution Control Committees for installation of RWH systems in their own premises. During the financial year, technical and financial assistance for installation of demonstrative rooftop rainwater harvesting systems was provided to the following State Pollution Control Boards:

1. Assam SPCB – in the premises of their headquarters at Guwahati 2. Chattisgarh ECB – in Regional Office buildings at Bilaspur and Jagdalpur 3. UPPCB – in the premises of Regional Office, Kanpur 4. APPCB – in the premises of upcoming headquarters and laboratory building in Hyderabad 5. Kerala SPCB – in the premises of their Regional Office, Ernakulam

EVALUATION OF TECHNOLOGICAL AND MANAGEMENT PERFORMANCE OF CETPS

The Ministry of Environment & Forests, GOI, has so far approved 133 Common Effluent Treatment Plant (CETP) projects of which 52 schemes have been completed and operational. The remaining 81 are under various stages of progress. The concept of CETP calls for management of technical, financial and institutional aspects and their inter-relationships to achieve their intended objectives. Few random studies of CETPs have shown mixed results about their performances. In order to develop comprehensive and systematic strategies for the effective functioning of CETPs, a project has been undertaken for a detailed study of performance and management of all the 52 CETPs that are currently operational in the country. The objectives of the project are:

1. Evaluation of the performance of various components of the CETPs including collection, transportation and treatment systems 2. Assessment of performance of various organizational/ management set-ups to identify their merits and drawbacks 3. Development of comprehensive monitoring and management strategies for effective functioning of CETPs under different types of management structure

Field study of the all the CETPs has already been completed. The aspects studied include:

• The unit-wise performance of wastewater treatment plant vis-à-vis design parameters and regulatory requirements • The operation and maintenance procedures, self-evaluation procedures, shortcomings and reasons thereof, and the improvement plans • Mode and appropriateness of disposal of treated effluent and sludge • Organizational aspects such as membership procedures, management structure, division of risks and responsibilities • Financial aspects such as membership contribution, mechanism for fixing and collection of treatment charges, and procedures for penalties and incentives

Some of the major observations of the study are:

1. A majority of the CETPs has not only the small-scale industries but also medium- and large- scale units as their members. 2. The current average inflow in 41 CETPs is in the range of 25-65% of the design capacity. Only 11 CETPs are currently receiving more than 90% of the design inflow quantity of industrial effluents. 3. None of the CETPs studied are compliant with respect to all the parameters prescribed as standards. This is despite the fact that a majority of them handling much less than design effluent quantities. 4. Energy costs has been reported to be the major component of the O&M cost of the CETPs. In some of States, the CETPs are charged at commercial rates (and not industrial rates) since by definition they are not industries. Almost all CETPs demand that they should be provided electricity at subsidized rates. 5. A majority of the CETPs has been registered as cooperative societies. Some have been registered as limited companies. 6. Where the member units of CETPs are of same category of industries, CETP treatment charges are usually fixed based on the quantity of the raw material processed or effluent generated. In case of mixed type of member industries, charges are based on the concentration of certain parameters identified by CETP management (such as pH, COD and/or TDS). 7. Three types of arrangements for management of CETPs were observed: 1. Plants managed by the CETP Association/ Company formed by the industries 2. Plants managed by private consultants/ contractors – including collection, transportation, calculation of charges, billing and revenue collection on management contract basis 3. Technical operation and maintenance of the hardware and laboratory contracted to private consultants. Billing and collection of treatment charges managed by the CETP Association/ Company. 8. None of the CETP management reported ‘financial crisis' in operating and maintaining the treatment plant.

DEMONSTRATION OF HOUSEHOLD MSW COMPOSTING UNIT IN PARIVESH BHAWAN

As a part of the Central Board's effort to demonstrate and promote decentralized MSW management, an aerobic natural composting system to process segregated kitchen wastes and horticultural wastes and to convert into a rich compost has been installed in Parivesh Bhawan. The capacity of the composting unit is 5 kg/day of kitchen wastes with an equal quantity of horticultural wastes, with a total volume of 3700 litres. The unit comprises a top composting chamber and a bottom maturation chamber. Segregated kitchen wastes are fed to the top chamber. Aeration of the heap is aided through the holes made on the walls of the chamber and also by turning of the contents once in a week. The material is transferred to the bottom chamber after a period of 8-10 weeks and allowed to mature for a period of 3-4 weeks. The mature compost is then taken out and placed in a pit under a soil cover for 4 weeks to take care of any pathogenic contamination. The compost produced is utilized within the Parivesh Bhawan premises. The system is user-friendly and will require minimal routine care on the part of households.

The benefits of adoption of household composting can be understood from the following estimate:

- Quantity of waste generated in Delhi : 6000 MT/day (average)

- Organic/ putrescible fraction estimated : 35% in MSW of Delhi (mostly kitchen wastes)

- Estimated quantity of MSW that can be : 2100 MT/day composted at household level

- Assuming only 50% of household adopt : 1050 MT/day composting of kitchen wastes, quantity of MSW composted

- Quantity of final compost product (at 60%) : 630 MT/day

- Annual value of compost produced : Rs. 56.7 Million/ year @ Rs.250/ MT of compost

- Savings due to reduction in transportation : Rs. 1.9 Million/ year (assuming 4 MT/trip, average trip length of 5 Km., and 5 Km/ L of diesel)

Total Economic value of benefits : Rs. 58.6 Million/ year

INTRODUCTION OF ECONOMIC INSTRUMENTS FOR INDUSTRIAL POLLUTION CONTROL

Environmental pollution imposes costs on the society. The costs of the products less often reflect the costs borne by the society (cost of damages to the society or social costs) due to pollution caused by the manufacturing/ consumption of the products. The unaccounted costs are referred by economists as ‘external costs' or simply ‘externalities'. In the case of pollution, the social costs are negative externalities.

Originally, it had been considered that prescribing effluent/ emission standards and enforcing the same through legislations is the strategy to prevent impacts of pollution and hence the negative externalities. This strategy is referred to as the ‘command-and-control (CAC) strategy'. The measures taken under CAC strategy are essentially a set of ‘dos' and ‘don'ts' mandating ‘end-of-pipe' emission/ discharge standards. With increasing array of issues faced in implementing pollution control laws through regulatory approach, there is a growing interest in the Government to adopt alternative frameworks for pollution abatement and environmental protection.

Economic Instruments (EI) are being considered as a viable option to effectively internalize the negative externalities of pollution and also to implement the ‘polluter pays principle'. In simple language, an economic instrument (EI) is a policy tool, which alters the behaviour of economic agents (firms/industries or households) by changing the nature of economic incentives (or disincentives) these agents face. In the context of application of EIs to pollution control, these can be further differentiated as direct and indirect instruments. Direct EIs price and charge the economic agents directly based on the quantity of a natural environmental resource used or pollution generated to induce internalization of the external costs of pollution. Indirect EIs , on the other hand, increase (or, decrease) the prices of inputs or outputs or both of a pollution generating activity of economic agents.

Charging an industry based on the concentration or quantity of BOD in the discharged effluent – pollution charges - is a direct EI, whereas, levying a tax on petrol to control vehicular emissions – eco- taxes - is an indirect EI. EIs would not only help to improve environmental quality in an economically efficient manner, but also generate additional revenues that can be used to support activities related to environmental protection.

The Ministry of Environment & Forests (MoEF), Government of India has constituted a Task Force under the Chairmanship of Special Secretary, MoEF to examine the subject of introduction of economic instruments for prevention and control of industrial pollution in India. As a part of this exercise, CPCB has evaluated all the existing environmental legislations and has made the following recommendations to the Task Force:

1. Nation-wide introduction and implementation of pollution charges/ environment user fees can be done under Water Act, Water Cess Act, and Environment (Protection) Act. However, it will need extensive amendments in these legislations. 2. From among the existing environmental legislations, Water Cess Act, 1977 is more amenable (than Water Act, 1974 and E(P) Act, 1986) for making amendments for introduction of pollution charges for water pollution control, and hence, this Act can be preferred for these purposes. 3. However, it is advisable to come out with a new comprehensive legislation exclusively for the purpose of introduction of environment user fees in all spheres of environmental protection/ pollution control. 4. Before, indulging in a large exercise, Sections 3,6 and 25 of the E(P) Act, 1986 can be used to experiment and evaluate the working of pollution charges through demonstration projects through issue of notifications. Any such notification shall be for a specific period and shall be made applicable for a specified area. e-GOVERNANCE IN CPCB

Software Development for e-Governance

An application software has been developed for shifting towards e-governance. The software includes modules on public complaints, legal matter, parliament matter, activities of Environmental Surveillance Squad for creating database to help quick analysis and retrieval of information. These modules, after testing and verification, will be made operational. Besides, development of software on budget monitoring and finance & accounts is under progress.

Creation of Environmental Data Bank

Necessary software for creating Environmental Data Bank has been developed. The software is under testing & verification and will be, used for building up database on various environmental components. This would not only make useful information/data available at one place but also on-line for quick & easy access.

Up-gradation of Web Site

CPCB's website is being continuously upgraded and updated. In order to make present website more interactive, informative and user-friendly, it has been redesigned and new website was launched in March 2003.

Local Area Networking

Internet services alongwith CPCB's website are made available round the clock. Network and mail services have been made available to all users of CPCB HQ. Use of stationeries viz. paper, floppies etc. has been considerably reduced by making optimum utilization of Local Area Network.

Software Upgradation
