MUTP places considerable emphasis on improving public transport including the railway capacity. Environmental Assessments (EA) was done for some of these sub-projects in the years 1996 to 1998. Also, a consolidated EA was prepared for the entire MUTP project. Environmental Management Plans (EMP) was prepared as a part of these EAs, which included mitigation measures for minimising adverse environmental impacts. Currently, several of these sub- projects are in different stages of construction and MMRDA desires to carry out an assessment of the relevant EMPs. This assignment pertains to the EMP assessment/audit for the project involving conversion of the current 1500 V DC traction system to 25000 V AC system. This system is being implemented at various routes of both Westem Railway (WR) and Central Railway (CR). Mumbai Metropolitan Region Development Authority (MMRDA) has retained the services of Serene Environmental Services (SES) to carry out Environmental Audit for railway projects of MUTP. 2.0 OBJECTIVES OF THE STUDY The Objectives of Environmental Audit are as follows: * Assess whether any activity of the project will have impacts on the environment such as construction of sub-stations within coastal regulation zone. * Assess impacts of disposal of old DC transformers. * Suggest environmental management plan, if required, for mitigating environmental impact. 3.0 PROJECT COMPONENTS The conversion is being done on various sections of both WR and CR. The broad components of the project are as follows: 1. Modification to the existing overhead equipment (OHE) to suit the insulation level of 25 kV. 2. Modification to the existing over line structures such as foot over bridges (FOB's), road over bridges (ROB's). Environmental Audit of DC- AC Serene Environmental Services Conversion Project of Railways 3. Power supply arrangement for 25 kV system 4. Modification to the existing low tension supplies 5. Modification to the telecommunication installation 6. Modification of the signaling installation with Audio frequency 7. Modification to Electrical Multiple Units (EMU's) 8. Modifications to Electrical Locomotives 9 Miscellaneous. Civil Works. These include the following: * Rebuilding/raising FOBs which are not having sufficient clearances to accommodate AC traction . Freezing the rail level under ROBs having critical clearances for AC traction by building ballast less track under them . Construction of electrical and service buildings such as substations, relay rooms, cable huts etc. Construction of quarters, office accommodations, office rest houses and senior subordinates rest houses as per requirements. At present 20 nos. of DC substations on Westem Railway and 49 nos. of DC substations on Central Railway are feeding DC power supply for running the trains in Mumbai Suburban Network. With switch over to 25 kV AC system, only 5 nos. of AC substations on Western Railway and 13 nos. of AC substations on Central Railway will suffice. The new substations will be provided at Mahalakshmi, Bandra, Jogeshwari, Borivali and Vasai Road on Westem Railway and at Chinchpokali, Vidyavihar, Thane, Thakurdi, Vangani, Karjat, Titwala, Asangaon, Kasara, Raoli, Mankhurd, Sea wood and Panvel on Central Railway. lmplementation Status- Central RailwaY On the Central Railway (CR) route, the conversion will be done in 4 phases: Phase 1: Vasai - Panvel - Jasai (Non-suburban route) Titwala - Igatpur stations Phase 2: Tilak-nagar - Panvel; Thane - Turbhe stations Phase 3: Thane - Kalyan stations Phase 4: Thane to CSTM stations Phase 1 and 2 are in progress. Phase 3 will commence after completion of Phase 1 and 2 Conversion in the suburban Phase 4 is expected to commence only after the year 2005. Implementation Status- Western Railwav On the Western Railway (WR) route, the conversion will be done in 3 phases: Phase 1: Borivali to Virar stations Phase 2: Andheri to Borivali stations Phase 3: Churchgate to Andheri stations . Environmental Audit of DC- AC Serene Environmental Services Conversion Project of Railways The OHE component in Phase 1 is about 90% complete. The expected date of completion for Phase 1 is December 2002. Phase 2 and Phase 3 implementation will begin after completion of Phase 1. The expected dates of completion for Phase 1 and 2 are December 2004 and December 2006 respectively. 3.1 Applicable Legal Requirements The applicable Indian environmental regulations, Wodd Bank policies/directives and GOM directives for all MUTP projects are given in detail in the Final Consolidated Environment Assessment (EA) Report on MUTP, 2002 prepared by MMRDA. This EMP's for the DC to AC conversion project have been prepared within the Policy and Legal Framework outlined in the Consolidated EA (CEA), Report for MUTP, 2002. The legal requirements applicable to the DC to AC conversion project are as follows: Indian Environmental and Other Regulations O Environmental (Protection) Act, 1986, associated Rules and Notifications under the Act. O The Maharashtra (Urban Areas) Preservation of Trees Act, 1975 O Land Acquisition Act 1894 (LA Act) O Maharashtra Regional and Town Planning Act, 1966 (MR&TP Act): O Development Control Regulations for Greater Mumbai 1991 (DCRs) World Bank Policies O Environmental Assessment (OP 4.01) 4.0 ENVIRONMENTAL IMPACTS Air Quality and Noise: Of all works in DC-AC project, only construction of AC sub-stations and laying of cables (from MSEB to substations) has a potential'of causing minor negative impacts. These impacts are typical to any minor civil construction. The magnitude of construction is small and the associated impacts are not considered significant. Prior permissions for cable laying will be taken from MCGM/Concerned Municipal Office. Environmental impacts from waste disposal Scrap DC electrical components such as insulators, cables, transformers etc. will be the main wastes from this project. Good
