The area was surveyed around the proposed POL Depot at Village Malom, Imphal. The field survey has been done for summer season during March 2011 to May 2011. The climatic condition during the study period is presented in report for all the stations where the modification is proposed. The pre-dominant wind direction in the region is W and SW. The calm situation prevailed for 21.10% of the time. The temperature varies from 9.5 0 C to 33.2 0 C, whereas, the relative humidity varies from 47% to 76 %. Total rainfall recorded during the study period was 263 mm. The ambient air quality is well within the limits as per the National Ambient Air Quality Standards in all the monitoring stations. The value of RPM varies from 26 to 41, SO 2 7 to 14 and NOx 8 to 18. All the results are reported in microgram per cubic meter (µg/m 3 ). The values of THC varies from 1.3 to 3.7 mg/m 3. The land use around the project site is pre-dominantly semi-arable. The sand, silt and clay varied from 22 67%, 21-73% and 2-12% respectively indicating that soil is Sand Silt. The soil moisture varied from 6.08 26.72%, while bulk density varied between 1.40 to 1.59. ph varies from 4.03 to 5.11 indicating slightly acidic that indicated to hinder the growth of agriculture crops. The conductivity varies from 160 to 460 µmhos/cm. The average concentration of nitrogen, phosphorus and potassium in the soil samples varied from 1.02 to 3.74 mg/100gm, 42.91 to 79.30 mg/100gm and 0.1 mg/100gm respectively. The organic matter content of soil varied from 1.15 to 3.95%. The average sodium absorption ration was 0.4, which is much below the value 9 where after the permeability of soil is affected. The ecological study of the area has been conducted within 15 km radius of the project site in order to understand the existing status of flora and fauna to generate baseline information and evaluate the possible impacts on biological environment. It has been assessed that the impact on local flora and fauna will be negligible due to the proposed project.
Page VI of VII The socio-economic conditions are presented in the report. The impact on socioeconomic environment as some direct or indirect employment will be generated during the construction and operation phases. 1.4 ANTICIPATED ENVIRONMENT IMPACTS AND ENVIRONMENT MANAGEMENT PLAN The potential impacts of the proposed pipeline have been limited to the proposed depot at Imphal. The land has been procured from state govt and no displacement of people is involved. No social issues are required to be addressed, as there is no rehabilitation and resettlement. The impact on soil quality is induced/ short term in nature, and can be avoided by applying good construction practices to reduce the impact, if any, on soils to a great extent. Adequate measures need to be worked out for minimizing the loss of soils, by way of storage of topsoil and then again laying it back after the completion of the construction of depot. Impacts on ambient air would mainly be due to dust emissions and movement of vehicles. However these impacts would be short-term in nature. Impacts on ambient air during operational phase would be due to emissions from DG set stacks and vehicles which will be very negligible and would be nullified by provision of scrubber and acoustic enclosure. The detailed environmental management plan has been presented in the main report. IOCL make sure that all the statutory norms, emissions norms for air, water, and noise shall be maintained during the construction and operation phases and in line with the EMP. 1.5 ENVIRONMENTAL MONITORING PROGRAMME It is imperative that the IOCL should set up regular monitoring locations to assess the environmental health in the post period. A post study monitoring programme is important as it provides useful information on the following aspects. It helps to verify the predictions on environmental impacts presented in this study. It helps to indicate warnings of the development of any alarming environmental situations, and thus, provides opportunities for adopting appropriate control measures in advance.
Page VII of VII 1.6 PROJECT BENEFITS The project will be improved supply position of the petroleum products in Manipur state, which is vital for economic growth as well as improving the quality of life. The improved petroleum supply will have strong logistical support for delivering the products to customers at better quality and better price. Availability of product in vicinity of demand location with safe operation will be beneficial to public at large. Establishment of large developmental projects improve the availability of the physical infrastructures like approach roads, drainage, communication and transportation facilities etc. The project will provide employment potential under unskilled, semi-skilled and skilled categories, so the direct employment opportunities would be generated.
