Tata chemicals Ltd. Executive summary of Draft EIA/EMP Report EXECUTIVE SUMMARY 1.1 Introduction M/s. Tata Chemicals Limited (TCL) was founded in 1939 and has operated a Soda ash plant since 1943, Captive Cogeneration Power Plant since 1944 and a Cement Plant since 1993 at villages- Mithapur & Surajkaradi, Taluka- Dwarka, District: Devbhumi Dwarka, Gujarat. The complex consists of various plants that include; manufacturing of Soda Ash and Sodium Bicarbonate, Caustic Soda, Liquid Chlorine, Hydrochloric acid, Bromine, Vacuum Evaporated Salt and Clinker/ Cement. Other supporting infrastructure facilities like; Captive Cogeneration power plant, Reverse osmosis based Sea Water desalination, a fabrication - machining shop, foundry, and facilities to handle materials (Limestone, Coal, Pet coke, Coke, Lignite, and Salt) storage godowns and product packaging unit, laboratories other maintenance shops are established within the premises with well-connected communication systems. Administrative offices for different department are also located within the TCL industrial complex. TCL has proposed for expansion of Soda Ash and Cement production capacities and Captive Cogeneration Power Plant within existing Chemical Complex. As per the EIA Notification 2006 and its subsequent amendments, the proposed Expansion of Soda Ash and Captive Cogeneration Power Plant falls under Category ‘A’ projects- 4(e) [Soda Ash Industry] and 1(d) [Thermal Power Plant] whereas expansion of cement plant (from 0.78 MTPA to 0.90 MTPA) falls under Category ‘B’ project- 3(b) [cement plants]. Since the project site is located within 5km from the boundary of marine sanctuary—the proposed expansion of cement plant will be treated as category ‘A’. Ministry of Environment, Forest and Climate Change has issued following Terms of Reference (ToR) for above proposals: 1.Expansion of Soda Ash and Captive Power Plant vide ToR letter No. J-11011/140/2016- IA.II(I) dated 02 August 2016 by EAC Industry-I Committee 2.Expansion of Soda Ash and Captive Power Plant vide ToR letter No. J-11011/66/1999- IA.II(I) dated 10January 2017EAC Industry-II Committee Combined EIA/EMP has been prepared for Industry-I and Industry-II project and combined Public Hearing will be conducted as per Para 6.0 (ii) of ToR letter dated 10 January 2017 and recommendation of ‘Cumulative EIA-EMP report to be prepared’ given in Minutes of Meeting of EAC (Industry-II).
