EExxeeccuuttiivvee SSuummmmaarryy 1.0 Introduction M/s. Hindustan Petroleum Corporation Limited (HPCL) is setting-up a grass root Rajasthan Refinery cum Petrochemical complex Project (RRP) of 9 MMTPA at Pachpadra Tehsil, District Barmer, Rajasthan. RRP is planned as a Joint Venture between HPCL and Govt. of Rajasthan (GoR). The cost of the project is about Rs. 37230 Crores. As per the Environment Impact Assessment (EIA) Notification dated 14th September 2006, the proposed project falls under ‘Category A’, listed at S.No. 4(a), requires preparation of EIA & RA Report to obtain Environmental Clearance (EC) from the Central Expert Appraisal Committee (EAC), MoEF, New Delhi. Environmental Appraisal Committee has given Terms of Reference (TOR) for refinery cum petrochemical complex for preparation of EIA and RA report. The proposed refinery cum petrochemical complex covers an area of 4813 acres which falls under the villages Sajjiyali, Roopji Kanthavad and Sambhara, in Pachpadra Tehsil, District: Barmer, Rajasthan. Out of the total area, 413 acres is reserved for township and raw water reservoir. It is about 100 km equidistant from Barmer and Jodhpur. The nearest airport is Jodhpur (100 km) while the nearest railway station is Balotra (13 km). There are no wild life corridors, archaeological monuments, places of tourist interests and Defence installations within the study area. No Reserved forest, National park, Wildlife Sanctuary and Tiger Reserves etc. exists within 10-km radius study area. 2.0 Project Brief The land requirement for the proposed RRP project is estimated to be around 4813 acres. The design life of the proposed RRP project will be 30 years. A crude pipeline of about 70 km length from Mangla Processing Terminal (MPT) and natural gas pipeline of about 60 km will be laid down from Raageshwari Gas Terminal (RGT) to the RRP site. Following is the configuration of the process unit capacities, material balance and products of proposed refinery cum petrochemical complex.

For construction phase of the project, approx. 5 MLD water requirement is envisaged in first year which shall be met from Nagana reservoir for a period of one year. Alternative water source for the construction water is also envisaged, i.e. CETP treated wastewater from Bithuja or Balotra for approx. 23 MLD (5 MIGD) construction water requirement. CETP treated waste water shall be further treated in UF+RO facility in refinery complex for making it suitable for construction purpose. In order to ascertain continuous supply of raw water to the RRP Complex, a backup water source (second source of water) from underground reservoir (Saline Aquifers from Thumbli, located at about 100 km from Pachpadra) equipped with desalination plant of equivalent capacity has been proposed. A captive power plant of 210 MW is proposed to meet the requirement of refinery cum petrochemical complex. 3.0 Description of Environment Baseline environmental studies have been carried for three months (Oct-Nov- Dec 2013). Studies have been carried out within in 10-km radius from proposed project for soil quality, ambient air quality, water quality, noise level monitoring studies, flora and fauna studies and demography. The scope of the present study is in line with the Terms of References (ToR) issued by EAC, MoEF, New Delhi vide letter no. F. No. J-11011/ 87/2013-IA II (I) dated September 27, 2013. Air Quality Status The region represents mainly rural environment and few sampling locations fall in moderate commercial and vehicular activities. The ambient air quality within 10-km E-3 Executive Summary radius around the proposed site was assessed at 11 locations. The villages are located quite far from the proposed project site. The average PM10 concentrations at all the locations varied in the range of 59-87 µg/m3, which represents background concentrations of rural environment and could be attributed to windblown soil dust and unpaved roads in the region. The PM10 concentrations for other locations were observed to be below 3 stipulated CPCB standards (24 hourly PM10 = 100 µg/m ). 3 The average PM2.5 concentrations ranged between 25-49 µg/m , which were 3 observed to be well below the stipulated CPCB standards (24 hourly PM2.5 = 60 µg/m ). 3 The average concentrations of SO2 and NOx ranged between 6-17 µg/m and 12-24 µg/m3 respectively. The levels of gaseous pollutants were below the 24 hourly 3 CPCB standards of 80 µg/m each for the SO2 and NOx. The average concentration of ammonia ranged between 19-25 µg/m3. All these values are well within the stipulated 3 CPCB standards (400 µg/m ). The observed average concentration of O3 at all the locations ranged between 9-17 µg/m3, which were much below the stipulated CPCB standards (8 hourly =100 µg/m3). The Ni concentration at all the locations was found to be in the range of 1.7-5.2 ng/m3, whereas the permissible limit of CPCB for Ni is 20 ng/m3. The Pb, As and BaP were Below Detection Level (BDL). The carbon monoxide concentration at all the locations varied between 0.18-0.77 mg/m3, whereas total hydrocarbons concentrations were in the range of 270-278 µg/m3. The area generally has low levels of pollutants in ambient air, which is well within the stipulated National Ambient Air Quality Standards (NAAQS). Noise Levels The noise level (LAeq) in residential areas varied between 43-54 dBA during daytime and between 32-42 dBA during night time. The noise levels during day and night time were below the stipulated noise levels in residential areas (Standards : Day time= 55 and night time 45 dBA). The noise level in commercial areas ranged between 57- 64 dBA during daytime and 40-54 dBA during night time. The noise levels were mostly around the stipulated noise levels as per the CPCB standards of commercial areas (day time= 65 and night time 55 dBA). The equivalent noise level recorded at different silence locations (schools) within the study area. Noise levels were found to be 41-48 dBA during daytime and 32 - 39 dBA during night time respectively. The noise levels were within the CPCB standards (day time= 50 and night time 40 dBA) for silence zone. E-4 Executive Summary Water Quality Status Eight surface water and three ground water samples were examined for physico-chemical, heavy metals and bacteriological parameters in order to assess background status of surface and ground water sources. The samples were analyzed as per the procedures specified in 'Standard Methods for the Examination of Water and Wastewater' published by American Public Health Association (APHA). Surface Water: The range of various water quality parameters varied as; pH: 7.5-8.5, turbidity: 1-10 NTU, total dissolved solids (inorganic): 195-254 mg/l, total hardness: 52-97 mg/l, chlorides: 18-103 mg/l, and sulfate: 4-10 mg/l. Fluoride was found to be 0.09-0.88 mg/l. Nutrients content in the form of nitrate and total phosphates were in the range of 0.2-8.6 mg/l and 0.16-1.31 mg/l respectively. Dissolved oxygen was in the range of 6.8-7.9 mg/l, whereas oil & grease were observed as 1-7 mg/l. The heavy metals like cadmium, chromium, zinc and arsenic were not detected; whereas Nickel, copper, lead iron manganese, cobalt and aluminum were found to be in the range of ND-0.001, ND-0.006, 0.004-0.616, 0.003-0.008, ND-0.001 and 0.09-2.20 mg/l respectively. It can be observed that the concentrations of all the parameters, in comparison with IS: 2296, come under Class ‘C’, category of drinking water source without conventional treatment but with disinfection. Ground Water: The groundwater quality showed high mineral contents in the form of total dissolved solids, total hardness, chlorides, sulfates, chemical oxygen demand, biochemical oxygen demand, sodium and potassium with their respective concentrations in the range as 2960 - 4055 mg/l, 688 - 1986 mg/l, 855 - 1949 mg/l, 400 - 562 mg/l, 16 - 80 mg/l, 2.6 mg/l, 586 – 680 mg/l, and 11.4 - 73.6 mg/l respectively.
