1. INTRODUCTION
1.1 Overview
1. This document is the Initial Environmental Examination for the Tranche 1 extension and augmentation sub-projects of Hyderabad Electricity Supply Company (HESCO). This IEE was prepared under TA4876 of the Asian Development Bank (ADB) Power Distribution and Enhancement Multi-tranche Finance Facility (PDEMFF).
2. Government of the Islamic Republic of Pakistan (GoP) has requested ADB to provide the PDEMFF to facilitate investments in power distribution and development of networks of eight independent distribution companies (DISCOs) that distribute power to end user consumers. The funding from ADB is expected to be released in stages (tranches). The Power Distribution Enhancement (PDE) Investment Program is part of the GoP long term energy security strategy. The proposed ADB intervention will finance new investments in PDE and assist capacity building of sector related agencies. The investment program will cover necessary PDE development activities in secondary transmission/distribution networks of eight DISCOs and the PDEMFF loan is proposed to be approved by ADB in 2008. The PDEMFF activities include extension (additional transformers) and augmentation (replacement of transformers with higher capacity) distribution line extensions, new and replacement distribution lines, additional sub-stations, transformer protection and other non network activities such as automatic meter reading, construction equipment and computerized accounting. New distribution lines to and from various network facilities and some of the above activities will also be included in the later tranches.

3. This IEE presents the results and conclusions of environmental assessment for the ten (10) extension and augmentation sub-projects proposed by HESCO and is submitted by Pakistan Electric Power Company (PEPCO) on behalf of HESCO. PEPCO has been nominated by Ministry of Water and Power (MOWP) to act as the Executing Agency (EA) with each DISCO being the Implementing Agency (IA) for work in its own area. PEPCO’s role in the processing and implementation of the investment program is that of a coordinator of such activities as preparation of PC-1s and PFRs, monitoring implementation activities; that includes submission of environmental assessments for all sub-projects in all tranches of the PDEMFF under ADB operating procedures. An IEE has been carried out to fulfill the requirements of ADB Guidelines (May 20031 2). This IEE study report is used to complete the
1 Initial project classification was carried out in 2006 and the Category is B. Most of the construction impacts will take place with only local impacts and there are no potential significant environmental impacts associated with the T1

(tranche one) sub-project construction. Initial environmental reconnaissance and REA carried out by consultants under ADB guidelines in May 2007 indicated that all the T1 sub-projects will be Category B. 2 Environmental Assessment Guidelines (ADB May 2003) 3 Category A projects that are deemed by ADB's chief compliance officer to be environmentally sensitive for the purposes of (i) the 120 day rule, and (ii) the environmental management plan requirement could involve projects that are near or in environmentally sensitive areas. At this stage no component of the T1 sub-projects under consideration is actually within a critical area and therefore the MFF tranche as a whole is Category B.

1.2 Requirements for environmental assessment
4. Under the MFF loan procedures of ADB, implementation of safeguards is to be achieved by environmental assessment of every sub-project to be undertaken following ADB Environment Policy (2002) and ADB Environmental Assessment Guidelines (2003). Power distribution enhancement and development type projects, that are limited to expansion of already developed facilities, have typically been classified as Category B. Each sub-project as been subject to environmental assessment after categorisation and the focus was on the most significant issues.
5. Under GoP regulations, the Pakistan Environmental Protection Agency Review of Initial Environmental Examination and Environmental Impact Assessment Regulations (2000) categorizes development projects into two schedules according to their potential environmental impact. The proponents of projects that have reasonably foreseeable impacts are required to submit an IEE for their respective projects (Schedule I).
Page 4 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
6. Projects that have more adverse environmental impact (Schedule II) are required to submit an environmental impact assessment (EIA) to the respective provincial Environmental Protection Agency (EPA). Distribution lines and sub-stations are included under energy projects and IEE is required for distribution lines of 11kv and less and large distribution projects (Schedule
Page 5 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
I). EIA is required by GoP for all projects involving transmission/distribution lines of 11kv and above and for grid sub-stations (Schedule II).
7. Expansion of facilities within existing sub-stations including extensions and augmentations of facilities within existing sub-stations are not listed as requiring environmental assessment. However because all the projects involve distribution equipment of 11kv and above at grid sub-stations there could be a technical requirement for EIA under GoP laws.
8. In that context a Framework of Environmental Assessment (FEA) on power extensions and augmentation sub-projects has been prepared by consultants and submitted to the Pakistan EPA, after hearings with provincial EPAs, which sought to “exempt” preparation of EIA/IEE for such small-scaled sub-projects such as those covered by this IEE.
9. In response to the FEA submitted by NTDC to the Pakistan EPA4 it has been clarified that all proponents must follow section 12 of the Pakistan Environmental Protection Act for all projects and furthermore that, only for augmentation projects by following the FEA, the required procedures under section 12 would be completed. Pakistan EPA has also assumed that all proponents will consult with the relevant provincial EPAs (PEPA) and follow their advice. In 2006 Punjab EPA requested disclosure of the scope and extent of each subproject in order that the Director General of PEPA can determine if additional land is required and the need for IEE or EIA.
1.3 Scope of the IEE Study and Personnel
10. This IEE study has included field reconnaissance for all 10 of the sub- projects with surveys taking place from June to September 2007. The Study Area for each subproject was the sub-station and immediate environs. The areas inside the sub-stations for improvement works were identified and the sensitive receivers immediately adjacent to the sub-stations were recorded, including any irrigation facilities, water supply, habitable structures, schools, health facilities, hospitals, religious places and sites of heritage or archaeological importance and critical areas5 within about 50m of the edge of the sub-station boundary walls.
11. The field studies were undertaken by a core study team with experience of environmental assessment for power projects in Pakistan. Mrs Sayeda Bushra Waheed, Mr Wali Waheed. Dr David Green International Environmental Consultant (IEC) conducted preliminary scoping, surveys and assessment activities and coordinated the field surveys and analysis. Mrs Sayeda Bushra Waheed, Mr Waheed and Dr Ahmad were also responsible to supervise collation of information and co-ordinate the various public consultation activities. Dr David Green, provided leadership and guidance with regards to the essential detailed assessments of design, construction, operational and decommissioning impacts, noise, air quality and waste disposal. The environmental team also benefited from technical support and other important information on the impacts of the proposed power works provided in feasibility

Page 6 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
reports prepared for HESCO6, by expert consultants dealing with engineering, power transmission, socio-economic, re-settlement and institutional aspects.
12. The study process began with scoping and field reconnaissance during which Rapid Environmental Assessments2 were carried out to establish the potential impacts and categorization of network enhancement activities. The environmental impacts and concerns requiring further study in the environmental assessment were then identified. The methodology of the IEE study was then elaborated in order to address all interests. Subsequently both primary and secondary baseline environmental data were collected and the intensity and likely location of impacts were identified with relation the sensitive receivers; based on the work expected to be carried out at each site. The significance of impacts from the power transmission expansion works was assessed and, for those impacts requiring mitigation, measures were proposed to reduce impacts to within acceptable limits.
13. All the extension and augmentation projects covered in this IEE will only involve work within an existing sub-station to either, (i) replace an existing transformer with one of a higher capacity (ITC or augmentation) or (ii) add a transformer (extension). Therefore in these projects that involve work within an existing sub-station to improve the network performance the sole stakeholder is HESCO. Therefore the requirement for public consultation (PC) can be seen to be satisfied by consultation with HESCO who are clearly in support of their own project. Therefore under ADB requirements, the need for environmental assessment process to include meaningful public consultation during the completion of the draft IEE can be seen to be satisfied by the support of HESCO for their own projects.
1.4 Policy and Statutory Requirements in Pakistan
14. Direct legislation on environmental protection is contained in several statutes. The Pakistan Environmental Protection Act (1997) has bearing on this IEE. Since the projects covered in this IEE will only involve work within an existing sub-station other environmental legislation will not be triggered.
15. The Constitution of Pakistan distributes legislative powers between the federal and the provincial governments through two ‘lists’ attached to the Constitution as Schedules. The Federal List covers the subjects over which the federal government has exclusive legislative power, while the Concurrent List contains subjects regarding which both the federal and provincial governments can enact laws. “Environmental pollution and ecology” is included in the concurrent list; hence both the federal and the provincial governments can enact laws on this subject. However, to date, with a few exceptions the federal government has enacted laws on environment, and the provincial environmental institutions derive power from the federal law.
National Environmental Quality Standards
16. The PEPA covers the improper disposal of all solid and liquid waste and specific limitations are placed on wastes and emissions from particular industries. The National Environmental Quality (Protection and Quality Regulations 1990, 1996 and 2000) identify specific industrial sources for control and an Environmental Protection License is required to discharge
6 Feasibility reports produced by the BPI consultants team under TA 4876 PAK.
Page 7 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
waste to the environment under controlled conditions. Where the project contractors require cement, concrete or granite based products for power improvement the materials must be obtained from facilities having a relevant and current Environmental Protection License.
Solid waste management
17. The vast majority of waste in Pakistan comes in the form of domestic refuse and the requirements for solid waste management from such sources are covered by local authority legislation which has allowed some reasonable control of waste management in some urban areas. Elsewhere in the country the municipal or village authorities or TAHSIL (not typical of the areas in which the HESCO sub-projects are located) are responsible to ensure proper disposal. However the lack of technical and financial resources has frustrated waste management planning. Fly tipping of waste outside towns and villages away from habitation is not an uncommon sight outside some district centers of habitation.
18. There will be waste associated with the HESCO addition and augmentation projects but unusually in this case the majority of likely waste will be in the form of small amounts of construction west and any leaked or residual transformer oil that may fall to the soil. The replaced transformers will be retained, stockpiled and reused.
1.5 Structure of Report
19. This report reviews information on existing environmental attributes of the areas around the Study Area. Geological, hydrological and ecological features, air quality, noise, water quality, soils, social and economic aspects and cultural resources are included. The report predicts the probable impacts on the environment due to the proposed project enhancement and expansion. This IEE also proposes various environmental management measures. Details of all background environmental quality, environmental impact/pollutant generating activities, pollution sources, pollution control equipment, predicted environmental quality and related aspects have been provided in this report. References are presented as footnotes throughout the text.

2. DESCRIPTION OF THE PROJECT
2.1 Type of Project
20. The sub-projects in this IEE are all improvements to the equipment that supports the power distribution network at ten (10) existing distribution grid sub-stations (DGS) that have been prioritized by HESCO and selected to be included in the PDEMFF Tranche 1. The proposed works will all be within existing DGS according to HESCO.
21. Of the sub-projects selected in Tranche, 3 are extension subprojects, and 7 are augmentation sub-projects (Table 2.1). The environmental assessments that have been carried out follow ADB Environmental Assessment Guidelines 2003 and GoP’s environmental assessment regulations and guidelines.

2.2 Categorization of the Project
22. Categorization is based on the most environmentally sensitive component of the Project and therefore the ten sub-projects at the existing DGS are categorized as a Category B. Tranche 1 is also Category B under ADB requirements2 and this IEE report is based on that assumption.
23. At this stage the methods to install or replace the transformers are fairly well defined. There are few if any potentially significant environmental impacts and the works will all be within the twenty five existing DGS and will not encroach on any land outside the sub-stations according to LESCO. There is no foreseeable significant disturbance outside the substations and waste disposal should not involve significant impacts if routine environmental management procedures and engineering controls are implemented thoroughly.
24. The aspects of the project with potential for any likely environmental impacts have been assessed, focusing on significant impacts from the extension and augmentation and any knock on effects from impacts such as waste disposal.

2.3 Need for the Project
25. Pakistan is a country with an economy of improving performance with a wide network of power distribution. However the standards and conditions of the power distribution are inadequate to meet rapidly growing power demand. This situation limits reliable power distribution and therefore the contribution of the power sector to national development and economic growth. To cope with the constraints, the existing power distribution infrastructure has to be improved and upgraded. The overall contribution of power infrastructure also requires institutional arrangements and capacity that support strategic management of the sector, and planning and management of investments. Overall the proposed PDEMFF Project has been designed in addressing both investment and institutional aspects in the sector.
26. The Tranche 1 projects will contribute to the improvement of the overall performance of the power distribution sector, improving distribution efficiency, broadly widening access to power to drive economic opportunities. The beneficiaries of the sub-projects will be people, companies, and government and non-government agencies in Pakistan that use power distribution services directly and indirectly. Communities indirectly served by the sub-projects will benefit from improved, secure faster distribution services. Power users will benefit in terms of secure power and improved power safety and potentially increased productivity.
2.4 Location and Scale of Project
27. The extension projects will all be within the ten existing DGS (Figures 2.1 and 2.2, Appendix 1A-1D) and will not encroach on any land outside the sub- stations.
Page 10 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
28. The extension sub-projects will involve the delivery and connection of an additional transformer in line with other transformers within the available space in an existing DGS.
Page 11 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
29. The augmentation sub-projects will replace an existing transformer in an existing DGS with a transformer of a higher capacity (ITC or augmentation). The transformer that is replaced will not be wasted but will be removed and transferred to at another HESCO facility where it will be reconditioned, stored and eventually transferred to another DGS to be reused. The Project Proponent (HESCO) plans to have the T1 completed by mid to late 2009. The details for the implementation of the 10 augmentation and extension sub- projects are in development.
2.5 HESCO Subprojects
30. None of the 10 subprojects are in Hyderabad city, but in other cities and villages, in Hyderabad district, and in Khairpur, Larkana, Bedin,Ghotiki Mirpur Khas, Sanghar Khairpur and Sukkur districts. The areas surrounding the relevant DGS are described in the reviews of environmental implications (REI) that are presented in Appendix 2. Photographs of the DGS are presented in Appendix 3. The jurisdiction of HESCO and location of the extension and augmentation projects are shown in Figure 2.2.

3. DESCRIPTION OF THE ENVIRONMENT
3.1 Sub-project Areas
41. The general characteristics of the extension and augmentation sub-project areas vary considerably. Many are in the urban areas in the HESCO jurisdiction, such as Sukkur SITE DGS, which is in the industrial area of Sukkur, and Jacobabad DGS, which is reported to be originally in a relatively remote and rural location. The Gambat and Thari Mirwah DGS were also in the rural fringe of their cities, but are now also surrounded by the expansion of cities. Gambat is surrounded on three sides by roads, and a railway line, is near the National Highway and Sukkur railway station. The Deharki DGS is still in a relatively rural type setting, in the middle of cultivated farm lands.
42. Typically there are a few buildings including residential and other social infrastructure within 50m of all the DGS.
43. In all DGS there is plenty of room for the construction of the extension and augmentation projects (Appendix 3). Access in all cases will be via the main entrance that joins the nearest main road.
3.2 Physical Resources Topography, Geography, Geology, and Soils 44. The area of the HESCO jurisdiction falls in Hyderabad district, as well as in Khairpur, Larkana Jacobabad , Badin , Ghotki (Dharki) and Sukkur districts of Sindh province. Topographically, Sindh sub project area can be divided into four distinct parts: the Kirthar range on the west; a central alluvial plain bisected by the Indus river in the middle, a desert belt in the east and the Indus delta in the south. The topography of the study area is generally flat and sandy, with some undulating terrain around a few sub-projects (Sukkur).
45. The sub-project DGS have all been designed to a very similar plan in various areas in the HESCO jurisdiction (Appendix 3). The natural soils within the sub-station boundaries have been covered with cobblestones, bricks or concrete in various areas.
46. Some small volumes of soil will need to be removed to create the footings and foundations for the new transformers. At this stage there is no identified requirement for disposal of any unsuitable spoil.
3.3 Climate and Hydrology
47. There is little variation of altitude above sea level between the DGS where the HESCO Tranche 1 sub-projects will take place and thus little or no variation between the climates of the project areas.
48. The climate of Sindh is reminiscent of the Sahara type and of that prevailing in the tropical region of low and dry lowlands. The temperatures are exceptionally high in summer but in winter they are comparatively low. The diurnal range of temperature is also great (e..g over 7°C in a single day at Jacobabad). Nearest the sea coast, the daily range of temperature is least. The highest humidity occurs in August viz 75% but the least in December, viz 58% in Lower Sindh and 47% in April in Upper Sindh.
Page 15 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
49. The scanty rainfall, the province gets is often due to cyclonic storms, caused by eastern and western disturbances, particularly the former. The annual rainfall is about 200 millimeters in Lower Sindh, but less than 100 in Upper Sindh. The average annual rainfall is hardly 125 millimeters.
50. Climate will have little bearing on the minor environmental impacts from the installation of transformers in the extension and augmentation sub- projects.
3.4 Groundwater and Water Supply
51. Irrigation is largely dependent on canals, but tubewells have also been sunk in areas where water is fit for irrigation. Ground water is generally brackish, but potable water is available in the belts along the Indus and canals. The strata in the subproject area are water bearing and alluvial deposits and giving groundwater potential throughout the subproject area. The watertabIe is about 15 to 20 meter below the surface. The watertable is not seasonal and dug wells do not generally run dry. The local population is generally reliant on supply from hand pumps. Piped water is available to 42% housing units of the Province which is 74% in urban areas and 17% in rural areas.
52. There is a potable piped water supply in the areas around most HESCO sub-projects. The water supplied in the Jacobabad DGS is not fit for drinking, and the DGS staff bring their own water for drinking, or buy water from a private supplier selling water from a pump installed near a canal. In the Gambat and Sukkur SITE DGS, the water supplied is sweet. In Dharki, the water supplied is foul smelling and turbid, but the people drink this water. The local population is generally reliant on supply from tube wells, as well as occasional open wells and hand pumps, where the water is tolerable, but use water from canals (which is usually visibly polluted) where ground water is too saline. There should be no impact on these sources of water by the construction of the extension and augmentation sub-projects.
3.5 Surface Water Rivers and Surface Drainage 53. The Indus is the main and only river that flows in the province. It receives no tribute from any prominent perennial stream in the long stretch of over 483 km in Sindh as there is little rainfall on the Eastern Highlands and the surface drainage is very poor.
54. Among the other old water channels of the Indus now converted into irrigation canals, are the Phuleli, the Gujah, the Gungrome, the Pinyari and the Gunjree. All these channels ultimately end in the delta creeks in the south.
55. There are numerous nais or mountain torrents, which are although not perennial but supply much water to the region. Among them are Gaj Nai, Mazar Nai, Khenji Nai, Delan Nai, Nari Nai etc.
56. The sub-project DGS have all the natural soils within the sub-station covered but the cobblestones allow surface water to drain away from some areas to the underlying soil. In other areas brick and concrete channels divert rain water to surface drains.

3.6 Air Quality
57. Since all the districts in the study area are basically dry, particulate pollution in the air is often high during hot, dry and windy days. Movement of motorized vehicles can also raise dust along unpaved roads. Otherwise, air quality in the most of the sub-project area appears fairly good based on observation during the study period although areas nearer the busy main roads are clearly impacted by vehicle fumes and dist. It is unlikely that large powered mechanical equipment will be needed for the extension and augmentation projects other than delivery lorries and lifting cranes.
58. There may also be neighbouring domestic sources of air pollution, such as emissions from wood and kerosene burning stoves as well as small diesel standby generators in some households. Other industrial sources are very few and limited to occasional factories. The major source of atmospheric pollution for the operational phase will be from vehicles on nearby roads and any industrial facilities nearby. Such emissions will be very well dissipated in the open terrain.
59. The other major source of air pollution is dust from arising from construction or other ground or soil disturbance. The extension and augmentation projects may in some cases require minor civil works to create or repair or improve supporting foundations for transformers.
3.7 Noise and Vibration
60. Noise from vehicles and other powered mechanical equipment is intermittent in most urban areas. There are also the occasional calls to prayer from the PA systems at the local religious locations and there are other occasion disturbances typical of the urban setting. However the proposed power extension and augmentation projects should not be noisy or create vibration nuisance.
3.8 Ecological Resources
61. The dominant vegetation of the province is indicative of its hot and dry climate, which is composed of open communities of deciduous and xerophytic trees and shrubs. Sindh soil and climate are suitable for plants which grow well in Africa, Arabia, and Iran, etc. Some one has said that it is certain that any thing can grow in the Indus loam.
62. The region is also dotted with ditches and ponds, and seasonal lakes which abound n plants of aquatic and semi-aquatic habit. A number of herbal or medicinal plants are found in the province. The mangroves have their own unique association of plants and animals.
63. In some respects the fauna of Sindh differs widely from that of other parts of the Indo-Pakistan subcontinent, having members from the Palearctic and Ethiopian zoogeographical regions, except animals peculiar to heavy forests and swamps. Sindh is fairly rich in mammals, reptiles and birds, the latter consisting of a large number of seasonal migrants.
Page 17 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
64. Among the living forms of 73 mammals, 20 belong to Carnivora, 20 to Chiroptera, 4 to Insectivora, 15 to Rodentia, 9 to Ungulata, 4 to Cetacea and only one to Pholidota.
65. Although this wildlife, which was once diverse and abundant, is now reduced almost to extinction. There are thus no significant terrestrial or aquatic biological resources in the urban areas near the sub-projects. No protected or religious trees have been identified in the sub-stations. There are a few planted trees and shrubs in sub-station gardens that may act as food trees for some birds.
66. The rest of the land adjacent to the sub-stations is mostly dominated by urban or agro-ecosystems. Home gardens also play a role in the local ecology. Some gardens are fairly large and many species of flora, including large trees are present but these would not be affected by the extension and augmentation sub-projects in Tranche 1.
67. None of the extension and augmentation sub-projects in Tranche 1 is near any area devoted to the preservation of biodiversity through dedication as a national parks and wildlife sanctuary. There are no protected areas near the transmission alignment.
3.9 Economic Development Agriculture, Industries, and Tourism 68. Agriculture: The main crops in the subproject area during winter are wheat, gram, rapeseed, mustard, toria, barley and pulses, other cereals, and during summer cotton, rice, jawar, bajra, maiza and sugarcane.
69. Horticulture: Main fruits grown in the area include guavas, apple, mango, grapes, water melon, musk melon, dates, sugarcane, orange, lemon, grape fruit, mulberry, sweet lime, sour lime, mosami, kino, and vegetables like brinjal, potato, chillie, garlic, cauliflower, tomato, arum, radish, turnip, peas ladyfinger, and onion, etc.
70. Mining: There are only a few minerals of economic importance such as building stones, lime stones, glass sand, gypsum, flint stone, alum, shale, marble, crude oil and natural gas, etc. There are also oilfields in Khaskhali in Badin district, and Golarchi and Mari Gas Fields in Ghotki,
71. Industries: Sindh Province is now one of Pakistan’s most industrialized regions with much of its large scale manufacturing centers centered in Karachi. The share of Hyderabad and Sukkur Divisions in the industrial structure appears to be increasing. The industries in Hyderabad and Sukkur consist of vegetable oil, textile, soap, tanneries, biscuits, tobacco, leather, pharmaceuticals, agriculture implements and cement. Industries in Thatha and Larkana are sugar, paper, jute, etc. Similarly, industries of sugar, cotton ginning, flour, and rice husking are thriving in Shikarpur, Jacobabad, Nawabshah and Dadu.
72. There are thousands of industrial, commercial and agricultural businesses in the vicinity of the Tranche 1 extension and augmentation sub-projects which are reliant on the efficient distribution of electrical power.
Page 18 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
Transportation 73. The province is connected by road, railway and air with the rest of the country and outer world. A network of roads is spread out throughout the province. Two major highways, running along the east and west banks of the Indus river connect the province with Punjab. Another highway (RCD) from Karachi running parallel to the sea coast connects with Balochistan via Uthal, Bela and Khuzdar. A national highway from Rohri also connects to Balochistan via Sukkur, Shikarpur and Jacobabad. Towards east, the road from Hyderabad links Thar Desert at Umerkot and Mithi. The numerous minor and major roads, interlinked, traverse throughout the districts of the Province.
74. The subproject areas are also connected with other districts through railway lines. Two vital railway lines traverse the province, one towards Punjab and the other to Quetta.
75. Air service in the province is being planned to meet public demand. Quaid- e-Azam International Airport at Karachi is the largest in the country in terms of size and number of passengers handled, with offices of national and International Airlines. Other airports in the province are at Nawabshah, Hyderabad, Moenjodero, Sukkur, Mirpurkhas, Sehwan and Jacobabad, besides some smaller airfields for small planes. However, Boeing flights are possible at Sukkur.
76. The air, rail and road transport systems are all reliant to a large extent on electrical power, and thus the majority of the local population is reliant on the power network for transportation. Power Sources 77. The transmission lines for electrical power in the HESCO run in a complex grid with between sub-stations (Figure 2.2).
3.10 Social and Cultural Resources Population and Communities 78. The total population of Sindh was 30.4 million (m) as enumerated in March, 1998. The population of districts in which the HESCO sub-projects are located are: Badin 1.1 m, Thatta 1.1 m, Jacobabad 1.4 m, Larkana 4.2 m Shikarpur 0.9 m, Ghotki 1 m, Khairpur 1.5 m, and Sukkur 0.9 m.
79. The 1998 Census showed that the province is predominantly Muslim. They constitute 91 % of the total population; 88 % in rural and 95 % in urban areas. The important minority is Hindus who are 6.5 %. The percentages of other minorities are quite insignificant i.e. less than 1 % in the province.
80. Sindhi is the most pre dominant language spoken by 60% of the total population. It is more predominant in the rural areas representing 92% as compared to 26% in urban areas. Urdu and Punjabi are spoken by 22% and 7% respectively. Pushto, Balochi and Siraiki are spoken by 4%, 2% & 1% .while 5% speak other languages.
81. Among the employed population in the province, 50 % are self-employed (66% in rural areas as compared to 35 % in urban areas). Most self employed persons are males. The next important percentage is employees (private) at
Page 19 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
26 % with almost the similar percentage at 26 for males as compared to 18 % for females. The percentage of government employees has been reported at 12%, surprisingly higher at 20% for females as compared to 12% for males. The percentage of unpaid family helper has been reported at 7.3% in the province, more than five times females at 34% as compared to 6% males.
82. There are many newly developing urban localities where families from middle and upper classes of society from all religions and castes are taking up residence These new localities are also creating an increased demand for better provision of electrical power from the network.
83. None of the extension and augmentation sub-projects will require relocation or resettlement. There are many important cultural or archeological sites in Sindh, but there are no cultural and archeological sites located in the vicinity of the any of the Tranche 1 extension and augmentation sub-projects. Education and Literacy 84. Institutions for primary, secondary and graduate level education are available in every district, as well for technical education in the fields of medicine, engineering, commerce, agriculture, textile and education etc. There are ten universities in the province.
85. The literacy ratio of the province is 45%. It is higher for males (55%) than for females (35%). There are sharp differences in the literacy ratios of rural and urban areas and there is also wide variation between male and female literacy ratios in both the areas.
86. All the educational institutions are reliant on reliable power. Many Government and private schools are located near the Tranche 1 extension and augmentation sub-projects. Health Facilities 87. District Headquarter Hospitals are available in each district. At the divisional level, higher medical facilities are available like ultrasound and laboratories. In the provincial headquarters, medical facilities of the highest standard are available in famous hospitals such as Agha Khan University Hospital, Jinnah Postgraduate Medical Center, Cardiovascular Institute in Karachi, Liaqat Medical College, Chandka Medical College Hospital, Larkana, Civil Hospital Mirpur Khas and Fatima Jinnah Medical College Hospital, Nawab Shah. There are 320 hospitals, 1808 dispensaries, 150 maternity and child welfare centers, with total 26379 beds which does not include hospitals run by the federal government.
88. There are also other hospitals of voluntary and missionary organisations which provide health cover to the general public. Medical facilities are located near many of the Tranche 1 extension and augmentation sub-projects.

4. SCREENING POTENTIAL ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
4.1 Project Location Impact Assessment and Mitigation
89. The Tranche 1 extension and augmentation sub-projects will involve expansion of facilities within existing sub-stations (DGS) and therefore sensitive receivers (SR) are set well back from the power equipment outside the DGS boundaries. In the case many of the extension and augmentation sub-projects there some sensitive receivers (SR) within a few metres of the DGS boundary walls and the SRs are in the form of residential buildings, some schools and shops in the surrounding villages as shown in Attachment 2.
90. The location and scale of the works are very important in predicting the environmental impacts. This process of impact prediction is the core of the IEE process and it is critical that the recommendations and mitigation measures are carried out according to with reference to the conditions on the ground in the affected areas in the spirit of the environmental assessments process. In this section the potential environmental impacts are reviewed. If impacts are predicted to be significant enough to exceed accepted environmental standards, mitigation is proposed in order to reduce residual impact to acceptable levels and achieve the expected outcomes of the project being implemented. Therefore, it is essential that a proper analysis is carried out during the project planning period. In this regard, the impact prediction plays a vital role as these predictions are used for developing mitigation measures and any alternative options, if appropriate. When the detailed designs are completed the impacts and mitigation measures will need to be further reviewed to take account of how the contracts are set up and in the light of any fine tuning of the sub-projects.
91. The environmental management plan (Section 5 and EMP matrix Appendix 4) has been compiled based on the available information and shall be reviewed in due course at project inception and through construction in order to feed back and [provide revised mitigation for any significant unpredicted impacts. The analysis primarily the key environmental issues likely to arise from sub-project implementation, to prescribe mitigation measures to be integrated in the project design, to design monitoring and evaluation schedules to be implemented during sub-project construction and operation, and to estimate costs required for implementing sub-project mitigation measures. The EMP plan must be reviewed when the sub-projects reach the inception stage by the project management and be approved before any construction activity is initiated, to take account of any subsequent changes and fine tuning of the proposals.
4.2 General Approach to Mitigation
92. During the preparation for the sub-project construction phase the future contractors must be notified and prepared to co-operate with the executing agency, project management, supervising consultants and local population in the mitigation of impacts. Furthermore the contractor must be primed through bidding stages and the contract documentation to implement the EMP in full and be ready to engage trained environmental management staff to audit the effectiveness and review mitigation measures as the project proceeds. The effective implementation of the EMP will be audited as part of the loan
Page 21 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
conditions and the executing agency (PEPCO) must be prepared for this. In this regard the HESCO must fulfill the requirements of the law and guidance prepared by FEPA on the environmental aspects of power projects and the recommendations already made for sub-projects in this IEE and under Pakistan’s PEPAct law.
93. The location of the residences, temples, schools, hospitals and civic cultural and other heritage sites has been reviewed in Section 3. Few if any of the residences and schools are close enough to sub-projects that there will be potential impacts in the construction stage from disturbance and significant noise and dust. Water is available in the study area although surplus water may not always be available to suppress dust at many locations in the dry season.
4.3 Prevention of ground contamination
94. Best international practice includes control measures to contain oily residues. Transformer oil and lubricants that may be released in the operational stage from maintenance and from a catastrophic failure that would result in loss of all transformer oil. Transformer oil is supplied in drums from an imported source and tap tanks are topped up as necessary on site. There are also facilities in some sub-project DGS maintenance yards for recycling (dehydrating) oil for breakers.
95. The transformers, transformer oil stocks and the transformer oil dehydration machines or are not installed on impervious surfaces. Therefore in order to be in line with best international practice some mitigation measures are required to prevent soil contamination.
96. The areas upon which the new transformers, transformer oil stocks and the transformer oil dehydration machines located should have an impervious surface with bunding and high enough edges to capture 110% of the total volume of oil that is housed within the bunded area. Oil and oily residues should therefore be captured at source and maintenance should take place in these dedicated areas away from surface water resources. With such mitigation installed no impacts should arise in sub-projects. A programme to introduce bunding in all substations should be introduced in the medium to long term as the transformers are upgraded (ITC) or replaced as resources permit.
4.4 Cultural Heritage, Temples, Religious Sites, Social Infrastructure
97. The location of temples and other cultural and other heritage SR sites with respect to the sub-projects has been reviewed in Section 3. No temples or religious sites are so close to the works in the DGS as to cause a nuisance. There will be sufficient buffer distance between the works and the SR such that no major significant impact would be expected from the works. However provision should be made for public consultation to be undertaken at the implementation stage to ensure no nuisances arise.
98. The clinic/hospitals are all well separated from the boundary walls of the sub-project DGS and there will be sufficient buffer distance between the works and the SR such that no major significant impact would be expected from the works. However, public consultation should also be undertaken.
Page 22 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
99. The location of schools and some residences places them within 10m from the edge of the sub-project DGS boundary wall in many cases. Whereas the scale of the works for Tranche 1 extension and augmentation sub-projects is well within the DGS boundary wall there should be sufficient buffer distance between the works and all the SR such that no significant impacts can be expected from the works, particularly in terms of noise, vibration and dust. However provision should be made for public consultation to be undertaken at the implementation stage to ensure no nuisances arise.
4.5 Potential Environmental Impacts in Construction
Encroachment, Landscape and Physical Disfiguration
100. The extent of Tranche 1 extension and augmentation sub-projects is well within the existing DGS boundary wall and therefore no additional encroachment, landscape or impacts associated with physical disfiguration of the urban cityscape or rural landscape are expected from construction.
101. Potential disfiguration of the landscape can however result from the uncontrolled excavation of raw materials such as rock, gravel and sand from neighboring areas. Extraction of rock based materials is not necessary on these sub-projects and is already banned by the authorities except under license.
Cut and Fill and Waste Disposal
102. The Tranche 1 extension and augmentation sub-projects should not require any significant cutting and filling but minor excavations and piling will be required in the DGS where the new transformers are to be located to create the footings.
103. Mitigation measures must focus on the minimization of impacts. If surplus materials arise from the removal of the existing surfaces these can be used elsewhere on the sub-projects before additional soil rock, gravel or sand extraction is considered. The use of this immediately available material will minimize the need for additional rock based materials extraction. The extraction of raw materials should be minimized by the re-use on-site for landscaping of all rock and soil based materials extracted for excavation of foundations etc.
104. If off-site disposal of surplus materials is necessary this must also be negotiated through local authority approvals prior to the commencement of construction.
105. Contractual clauses should be included to require each contractor to produce a materials management plan (one month before construction commences) to identify all sources of cement and aggregates and to balance cut and fill. The plan should clearly state the methods to be employed prior to and during the extraction of materials and all the mitigation measures to be employed to mitigate nuisances to local residents. Mitigation measures shall seek to control the impacts at source in the first place. The construction supervising consultant (engineer) shall be responsible to update the cut and fill estimates and create Materials Master Plan to facilitate materials exchange between the different contracts in the Tranche 1 sub-projects to provide an overall balance for materials and minimize impacts on local resources.
Page 23 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
4.6 Trees, Ecology and Protected Areas
106. Surveys have been made at all sub-project locations and whereas trees are present in some sub-stations there should not be any need for disturbance of trees in the Tranche 1 extension and augmentation sub- projects.
107. If for some unforeseen reason Reserved Trees or other trees do need to be removed permission should be obtained from the forest authority after written justification.
108. At this stage no areas require removal of woodland. However if specimen trees of religious plantations are affected the owners should be given the resources and opportunity to reinstate the woodland long term and a plantation compensation plan should be drawn up to replant the woodland/trees. In the event that the land is not suitable for plantation then other areas should be identified to replace the cut trees and sufficient areas should be identified to allow plantation of trees at a rate of say 3:1. The replacement ration should allow for a high mortality rate among the newly planted trees in the dry environment or otherwise as based on advice from the forest authority.
109. A requirement shall be inserted in the contracts that no trees are to be cut in the DGS without the written permission from the Supervising Consultant who may permit the removal of trees if unavoidable on safety and technical engineering grounds after written justification.
4.7 Hydrology, Sedimentation, Soil Erosion
110. The Tranche 1 extension and augmentation sub-projects are all on flat sites and should only require minor excavations and piling. Therefore there is little potential for the works to have impact on local water resources. There should be no need for erosion control and there should not be any significant runoff from stockpiles.
4.8 Air Pollution from Rock Crushing, Cut, Fill, & Asphalt
111. Field observations indicate that ambient air quality is generally acceptable considering the urban and urban fringe environments where the Tranche 1 sub-projects are located. Any local emissions from powered mechanical equipment needed for the construction will to be rapidly dispersed and no impacts are expected.
112. Major earthworks are not envisaged but minor excavations and piling will be required in the DGS where the new transformers are to be located and to create the footings and bunds to contain leaked oily waste. Where earthworks are required they will contribute to increasing dust. However the scale of the works at any one location is not likely to cause excessive dust. Therefore dust control from works at this scale should be easy to achieve at little extra cost. In order to avoid complaints of dust nuisances the following mitigation measures should be carried out as a matter of good housekeeping: (i) Dust suppression facilities (back pack water sprayer) shall be available where earth and cement works are required.
Page 24 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
(ii) Areas of construction (especially where the works are within 20m of the SRs) shall be maintained damp by watering the construction area. (iii) Construction materials (sand, gravel, and rocks) and spoil materials will be transported trucks covered with tarpaulins. (iv) Storage piles will be at least 30m downwind of the nearest human settlements. (v) All vehicles (e.g., trucks, equipment, and other vehicles that support construction works) shall be well maintained and not emit dark or smoky emissions in excess of the limits described in the NEQS. 113. The need for large stockpiles should be minimized by careful planning of the supply of materials from controlled sources. If large stockpiles (>25m3) are necessary they should be enclosed with side barriers and covered with tarpaulins when not in use and at the end of the working day to enclose dust.
114. Bitumen will not generally be required. If bituminous compounds are to be applied by hand labor methods and melted in heaters the fuel used shall be kerosene, diesel or gas fuel. Fuel wood shall not be used for heating bitumen; neither should bitumen be used as fuel.
115. Bitumen drums should be stored in a dedicated area, not scattered around the sub-project and any small accidental spills of bitumen or chemicals should be cleaned up immediately. The waste including the top 2cm of any contaminated soil and disposed of as chemical waste to an approved landfill or approved local authority disposal site.
4.9 Noise, Vibration and Blasting
116. There will be no requirement for blasting for the Tranche 1 extension and augmentation sub-projects. At this stage the specific methods for installation of transformers with regard to supporting civil works is not known but soft ground is not generally present and piling should not be needed and would not be a preferred method for foundations in vibration sensitive DGS. Therefore noise and vibration should not be an issue during constructions of Tranche 1 extension and augmentation sub-projects.
4.10 Sanitation, Solid Waste Disposal, Communicable Diseases
117. The main issues of concern are uncontrolled disposal of waste by construction workers, unmanaged disposal of solid and liquid wastes into watercourses and natural drains. There should not be any significant amounts of waste from the works and because the works will be under close supervision of the HESCO authority within the DGS these issues can be controlled at source.
118. In order to maintain proper sanitation around construction sites the workforce will be allowed to use the flush toilets in the sub-station control, facilities.
119. Vectors such as mosquitoes should not be a significant consideration bearing in mind the type and scale of works for the Tranche 1 extension and augmentation sub-projects.
Page 25 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
4.11 Potential Environmental Impacts in the Operational
Air Pollution and Noise from the Enhanced Operations
120. Based on observations of many different types of transformer at numerous Tranche 1 extension and augmentation sub-project sites, noise and vibration should not be a nuisance to any nearby SRs. Although one transformer will be added for the extension projects the incremental addition to noise levels will not cause a significant disturbing effect for the SRs in the vicinity of the sub-projects.
121. Some switchgear that may be installed may contain SF6. Typically losses of the SF6 gas are very minor in the operational phase but it is noted that all halogenated gases can potentially accrue “greenhouse gas effects” if they are released in significant quantities. However well installed SF6 equipment should not leak significant amounts of gas and in leakage is checked routinely from all such equipment. Six monthly reports are already made in case there is a need for SF6 to be topped up. The maintenance of the equipment should be geared to achieve a gradual reduction in SF6 usage (leakage) which can therefore be monitored to slowly eradicate any such impacts. If SF6 leakage becomes excessive the respective plant will be overhauled to reduce eradicate the leakage.
122. If there is a suspicion that there has been a leak of sulphur hexafluoride or by products at any substation the immediate substation area should be evacuated, the controlling engineer must be informed, pending investigation by an authorized person. Thus atmospheric environmental impacts from SF6 can be mitigated and are not expected to be significant.
Pollution from Oily Run-off, Fuel Spills and Dangerous Goods
123. Control measures will be needed for oily residues such as transformer oil and lubricants. Transformer oil is supplied in drums from an imported source and tap tanks are topped up as necessary on site. There are facilities in some sub-project DGS maintenance yards for recycling (dehydrating) oil for breakers. However the areas upon which these recycling facilities are located have no dedicated drainage which can capture run-off. Oily residues and fuel should be captured at source and refueling and maintenance should take place in dedicated areas away from surface water resources. No significant impacts should be allowed to arise in sub-projects.
124. If for some reason there are oily releases they should be cleaned up immediately. The waste including the top 2cm of any contaminated soil and disposed of as chemical waste to an approved landfill or approved local authority disposal site.
4.12 Enhancement
125. Environmental enhancements are not a major consideration within the numerous Tranche 1 extension and augmentation sub-project sites. However it is noted that it is common practice at many such sites to create some local hard and soft landscaping and successful planting of fruit trees and shrubs has been accomplished in many sites. This practice should be encouraged as far as practicable.
Page 26 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
5. INSTITUTIONAL REQUIREMENTS & ENVIRONMENTAL MANAGEMENT PLAN
126. In this section, the mitigation measures that are required, for Tranche 1 extension and augmentation sub-projects, to reduce residual impact to acceptable levels and achieve the expected outcomes of the project, are discussed. The Environmental Management Plan is based on the type, extent and duration of the identified environmental impacts for Tranche 1 extension and augmentation sub-projects. The EMP has been prepared following best practice and by reference to the ADB Environmental Assessment Guidelines 2003.
127. It is important that the recommendations and mitigation measures are carried out according to the spirit of the environmental assessment process and in line with the guidelines. The EMP matrix is presented as Attachment 4. The impact prediction (Section 4) has played a vital role in reconfirming that typical mitigation measures and approaches will achieve the necessary environmental controls based on the feasibility and detailed design assumptions available at this stage.
128. Prior to implementation and construction of the sub-projects the EMP shall be reviewed by the HESCO and amended after detailed designs are complete. Such a review shall be based on reconfirmation and additional information on the assumptions made at the feasibility stage on positioning, alignment, location scale and expected operating conditions of the sub- projects. For example, in this case if there are any additional transmission lines or extension of the sub-station boundaries to be included, the designs may be amended and then the performance and evaluation schedules to be implemented during project construction and operation can be updated, and costs estimates can be revised. The IEE and EMP should than be revised on a sub-project by sub-project basis.
129. The IEE and EMP plan must be reviewed by the project management and if approved by the PEPA (if required) before any construction activity is initiated. This is also an ADB requirement in order to take account of any subsequent changes and fine tuning of the proposals. It is recommended that before the works contract is worked out in detail and before pre-qualification of contractors that the full extent of the environmental requirements for the subproject(s) and the IEE and EMP are included in the bidding documents. Past environmental performance of contractors and awareness of environmentally responsible procurement should also be used as indicators for prequalification of contractors.
130. In order to facilitate the implementation of the EMP, during the preparation for the construction phase the HESCO must prepare the future contractors to co-operate with all stakeholders in the mitigation of impacts. Furthermore the contractor must be primed through the contract documentation and ready to implement all the mitigation measures. HESCO will also need to confirm that contractors and their suppliers have complied with all statutory requirements and have appropriate and valid licenses and permits for all powered mechanical equipment and to operate in line with local authority conditions.
Page 27 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
131. The effective implementation of the EMP will be audited as part of the ADB mid term review of loan conditions and the executing agency must prepare for this at the inception stage.
132. The details of EMP given in the Attachment 4 are for the Tranche 1 extension and augmentation sub-projects. The EMP matrix will be different for the more complicated sub-station and line projects that involve impacts to land outside the existing sub-stations.
133. The impacts have been classified into those relevant to the design/preparation stage, construction stage and operation and maintenance stage. The matrix provides details of the mitigation measures recommended for each of the identified impacts, time span of the implementation of mitigation measures, an analysis of the associated costs and the responsibility of the institution. The institutional responsibility has been specified for the purpose of the implementation and the supervision. The matrix is supplemented with a monitoring plan for the performance indicators. An estimation of the associated costs for the monitoring is given with the plan. The EMP has been prepared following best practice and the ADB environmental assessment guidelines 2003.
126. It is strongly recommended that for sub-projects in future Tranches that the HESCO be prepared to engage more support where necessary especially if full scale EIAs are required for some line and substation subprojects (e.g. senior environmental specialist with at least 10 years experience in environmental management five years site experience in environmental monitoring and auditing) to guide the subsequent formal assessment and submission process under the PEPAct and monitor compliance with the EMP.
127. Environmental members will need a good level of awareness and will be responsible for addressing environmental concerns for sub-projects potentially involving hundreds kilometers of distribution lines and DGS. Whereas some of their work may in future be delegated to consultants they will need more training and resources if they are effectively provide quality control and oversight for the EMP implementation. They will require robust support from senior management staff members and the management consultant if they are to address all environmental concerns for the sub- projects effectively. Specific areas for immediate attention are to appoint environmental specialist(s) have them experienced or trained in EMP auditing, environmentally responsible procurement, air, water and noise pollution management and ecological impact mitigation. It is recommended that an environmental specialist consultant with 10 years experience be made available to all the DISCOS through the TA attached to the PDEMFF to cover these aspects full time for at least the first six months of the PDEMFF project and that on a call off basis with local support those services are retained for the life of the PDEMFF loan. Environmental staff members can than shadow the environmental specialist to improve awareness and hopefully provide independent quality control and oversight for the EMP implementation within 12 months.
128. In order to achieve good compliance with environmental assessment principles the graduate environmental staff for the project implementation team must be actively involved, prior to the outset of the
Page 28 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
implementation design stage, to ensure compliance with the statutory obligations under the PEPAct. It is also recommended that HESCO Board allow direct reporting to Board level from the in-house Environmental and Social Unit (ESU). If the ESU requires resources for larger sub-projects then environmental specialist consultants could be appointed through the relevant project implementation unit to address all environmental aspects in the detailed design. It is recommended that the project management unit (PMU) should liaise directly with the ESU to address all environmental aspects in the detailed design and contracting stages. The graduate environmental staff will cover the implementation of environmental mitigation measures in the project packages.
129. The environmental staff specialist will:
a. work in the PMU with HESCO to ensure all statutory environmental submissions under PEPAct and other environmentally related legislation are thoroughly implemented; b. work in the PMU with HESCO to ensure all environmental requirements and mitigation measures from the environmental assessment of sub-projects are included in the contract prequalification and bidding documents; c. work with HESCO to execute any additional IEE and IEE requirements needed due to fine tuning of the sub-projects and that environmental performance targets are included in the contracts prior to project commencement; d. work in the PMU with HESCO to ensure all environmental requirements and mitigation measures from the IEEs and IEEs and environmental performance criteria are incorporated in the sub- project contracts or variations and that the EMP is effectively implemented; e. work with management (consultants), supervising consultant and contractors to manage and monitor the implementation of the project EMP. f. work with management to ensure that the Environmental Assessment Review Framework (EARF) is fully applied, adequately resourced and implemented for future Tranches of the PDEMFF. 130. Overall implementation of the EMP will become HESCO’s responsibility. Other parties to be involved in implementing the EMP are as follows: Contractors: responsible for carrying out the contractual obligations, implementing all EMP measures required to mitigate environmental impacts during construction; and Other government agencies: such as regional PEPA and state pollution authorities, Department of Forests, Department of Wildlife Services, who will be responsible for monitoring the implementation of environmental conditions and compliance with statutory requirements in their respective areas and local land use groups at the local levels. 131. Considering that other government agencies that need to be involved in implementing the EMP, training or harmonization workshops should be conducted for all ESUs in all DISCOS every six months or twice
Page 29 of 33 Power Distribution Enhancement Project – HESCO Transformer Extension and Augmentation Subprojects Initial Environmental Examination
each year, for the first 2 years (and annually thereafter) to share the monitoring report on the implementation of the EMP in each DISCO and to share lessons learned in the implementation and to achieve a consistent approach decide on remedial actions, if unexpected environmental impacts occur.
132. The monitoring plan (Attachment 5) was designed based on the project cycle. During the pre-construction period, the monitoring activities will focus on (i) checking the contractor’s bidding documents, particularly to ensure that all necessary environmental requirements have been included; and (ii) checking that the contract documents’ references to environmental mitigation measures requirements have been incorporated as part of contractor’s assignment and making sure that any advance works are carried out in good time. Where detailed design is required (e.g. for power distribution lines and avoidance of other resources) the inclusion and checking of designs must be carried out. During the construction period, the monitoring activities will focus on ensuring that environmental mitigation measures are implemented, and some performance indicators will be monitored to record the Sub-projects environmental performance and to guide any remedial action to address unexpected impacts. Monitoring activities during project operation will focus on recording environmental performance and proposing remedial actions to address unexpected impacts. The potential to use local community groups contacts for monitoring should be explored as part of the activities in setting up the Environmental and Social Unit which should have regular meetings with the NGOs as a matter of good practice and to discuss matters of mutual concern.
133. At this stage, due to the modest scale of the new power distribution projects and by generally keeping to non-sensitive and non-critical areas the construction and operational impacts will be manageable. No insurmountable impacts are predicted providing that the EMP is implemented to its full extent and required in the contract documents. However experience suggests that some contractors may not be familiar with this approach or may be reluctant to carry out some measures. In order that the contractors are fully aware of the implications of the EMP and to ensure compliance, it is recommended that environmental measures be costed separately in the tender documentation and that payment milestones are linked to environmental performance, vis a vis the carrying out of the EMP.
134. The effective implementation of the EMP will be audited as part of the loan conditions and the executing agency must be prepared for this. In this regard the HESCO (the IA) must be prepared to guide the design engineers and contractors on the environmental aspects.

6. PUBLIC CONSULTATION AND INFORMATION DISCLOSURE
135. Approach to Public Consultation
136. The public consultation (PC) process with various stakeholders for Tranche 1 has been approached so as to involve public and other stakeholders from the earliest stages. Public consultation has taken place during the planning and design and viewpoints of the stakeholders have been taken into account and their concerns and suggestions for possible improvements have been included where appropriate. Much of the PC process to date has revolved around concerns for the mitigation of construction impacts and the possible side effects from the proximity of high voltage power lines. PC has therefore been conducted for the sub-station and line sub- projects that may incur some impacts over land outside existing sub-stations and that PC is reported in the dedicated IEEs for those sub-projects. There is also ongoing consultation for land acquisition and resettlement (LAR) and the completion of the Resettlement Plan (RP) is documented separately. It is expected that this process will continue through all stages of the sub-projects in order to accommodate stakeholders' aspirations and to orient the stakeholders positively towards the project implementation and where possible to harness co-operation over access issues in order to facilitate timely completion.
137. The Tranche 1 extension and augmentation sub-projects the whole of each sub-project in design, construction and operational stages is only likely to affect the areas within the DGS premises. There are unlikely to be any significant impacts outside the DGS except for perhaps temporary minor inconveniences to traffic when new transformers are transported to site. Therefore HESCO is the major relevant stakeholder and HESCO are in favour of and support their own sub-project proposals. However some consultation was also conducted with residents and other stakeholders near the HESCO extension and augmentation subprojects and the major concerns of the public, based on consultation at the substation projects, seems to be to get employment in the construction phases.

7. FINDINGS RECOMMENDATIONS AND CONCLUSIONS
7.1 Findings and Recommendations
139. This study was carried out at the planning stage of the project. Predominantly secondary data and site reconnaissance were used to assess the environmental impacts. The potential environmental impacts were assessed in a comprehensive manner. The report has provided a picture of all potential environmental impacts associated with the sub-projects, and recommended suitable mitigation measures. This study recommends that some further follow up studies are undertaken during project processing in order to meet the ADB requirements.
140. There are some further considerations for the planning stages such as obtaining clearance for the project under the Pakistan Environmental Protection Act (1997) but environmental impacts from the Tranche 1 extension and augmentation sub-projects will mostly take place during the construction stage. There are also some waste management issues for the construction and operational stage that must be addressed in the detailed design and through environmentally responsible procurement. At the detailed design stage the number of and exact locations for transformer extensions and augmentations and other enhancements may change subject to detailed surveys but the impacts are likely to be broadly similar at most locations and impacts have been reviewed in the environmental impact section of this IEE report.
141. The Tranche 1 extension and augmentation sub-projects require a number of key actions in the detailed design phase. Prior to construction the HESCO must disclose the projects to Federal EPA and receive clearance certification from the PEPA. HESCO must complete an EMP that will be accepted by the PEPA and agreed by the contractor prior to signing the contract. The information provided in this report can form the basis of any further submission to PEPA as required in future.
142. The reporting of extension and augmentation sub-projects are restricted to the enhancements indicated in this report but further details are required if land is required or for any other improvements along the alignment where land acquisition, resettlement and compensation may need to be considered. Based on the other sub-projects providing further documentation for any new future proposed alignments should not be difficult tasks and this can be conducted as the detailed designs are worked out and to dovetail with the existing system and minimize adverse impacts and maximize benefits. Social impact assessment and due diligence has been completed in tandem with this IEE for relevant sub-projects.
143. During the commissioning phase waste disposal monitoring should ensure that statutory requirements have been met. Monitoring activities during project operation will focus on periodic recording environmental performance and proposing remedial actions to address any unexpected impacts.

7.2 Conclusion
144. There are no insurmountable environmental impacts for the Tranche 1 extension and augmentation sub-projects that are feasible and sustainable options from the power distribution, engineering, environmental, and socioeconomic points of view. Implementation of the EMP is required and the environmental impacts associated with the sub-project need to be properly mitigated, and the existing institutional arrangements are available. Additional human and financial resources will be required by the HESCO to complete the designs and incorporate the recommendations effectively and efficiently in the contract documents, which should be linked to payment milestones. The proposed mitigation and management plans are practicable but require additional resources.
145. This IEE, including the EMP, should be used as a basis for an environmental compliance program and be included as an appendix to the contracts. The EMP shall be reviewed at the detailed design stage. In addition, any subsequent conditions issued by Pakistan EPA as part of the environmental clearance should also be included in the environmental compliance program. Therefore, continued monitoring of the implementation of mitigation measures, the implementation of the environmental conditions for work and environmental clearance, and monitoring of the environmental impact related to the operation of the Tranche 1 extension and augmentation sub-projects should be properly carried out and reported at least twice per year as part of the project performance reports.
