Ramky Enviro Services Pvt. Ltd. 3 Traffic Impact Assessment for Transportation of Coal by Road for STPP 1.0 INTRODUCTION 1.1 Project Background In year 2010 M/s. Singareni Collieries Company Limited (A Government Company) obtained Environmental Clearance (EC) vide Lr. No. J-13012/88/2008-IA.II (T), dated 27.12.2010 for 2x600 MW coal based thermal power plant units from Ministry of Environment Forest and Climate Change (MoEF&CC) Government of India. Environmental Clearance order copy is enclosed as Annexure 1. During the establishment of the Singareni Thermal Power Plant (STPP), SCCL proposed coal transportation from their coal fields to site by Indian Railways using BOXN/BoBR rakess. The 1st unit construction has been completed in the Sep 2016 and the 2nd unit construction completed in the year Dec 2016. SCCL has requested MOEF&CC for temporary permission for transportation of coal by road instead of using dedicated railway line till its completion. The MoEF&CC vide its letter dated 10.08.2016 has granted the same for period of two years and is going to laps by August „2018. Hence, SCCL requested for extension of time period for temporary transportation of coal by road for further one year period and submitted the online application on 15.06.2018 for EC Amendment. The proposal was discussed in 18th Re Constituted EAC meeting for TPP held on 27.06.2018 and sought additional information “Traffic Impact Assessment study which includes impact on traffic load, ambient air quality and noise levels. Line source modelling will be conducted for estimating the incremental concentrations and impact area along the road. Area source modelling shall be conducted for loading and unloading points for predicted the environmental impacts, based on baseline data collected AAQ along the roads”. The amended EC vide Lr. No. J-13012/88/2008-IA.II (T), dated: 10.08.2016 enclosed as Annexure-2. 1.2 Present Proposal As suggested EAC in 18th meeting for carrying out the above study, SCCL hired M/s. Ramky Enviro Services Pvt Ltd., as its environmental consultant. The SCCL power plant is located at Pegadapalli Village, Jaipur Mandal, Mancherial District of Telangana State, between Latitude – 180 48‟ 40” North and 180 50‟ 20” North and Longitude – 790 34‟ 07” East and 790 35‟15” East. The proposed plant site is connected to Chennur – M/s. Ramky Enviro Services Pvt. Ltd. 4 Traffic Impact Assessment for Transportation of Coal by Road for STPP Mancherial section of NH-16 and Kazipet – Ballarsah section of South Central Railway and located 14.6 Kms away from Mancherial in the South-East direction. For the purpose of completing the traffic impact assessment, traffic load, ambient air quality and noise levels, an inspection of the existing road network has been undertaken. Required baseline data has been sourced/collected from field survey. To supplement the information received from the various sources, traffic counts have also been undertaken at important intersections in proximity to the transportation area. 1.3 Study Methodology The objective of the assessment is to evaluate the impacts on traffic load, ambient air quality and noise levels due to transportation of coal by road and also due to loading and unloading activities at mine and power plant. Traffic impact assessment study includes the following tasks: Inspection of the road network between coal loading and unloading points and its surrounding areas. Review of existing road network operations including survey of existing traffic on the roads connecting to power plant. Baseline data generation for ambient air quality and noise levels, movement of vehicles on important roads connecting loading and un loading points of coal. Line source and area source modelling for predicting environmental impacts due to coal transportation on surrounding areas along the road. M/s. Ramky Enviro Services Pvt. Ltd. 5 Traffic Impact Assessment for Transportation of Coal by Road for STPP 2.0 PROJECT DESCRIPTION 2.1 Project Overview The Unit 1 COD completed on 25.09.2016 and Unit 2 COD completed on 02.12.2016 and both the units are under operation. The required coal for both units (2 x 600 MW) are met from the nearby operating mines of SCCL viz. SRP OC-I, SRP OC-II, RKP OC Phase-I. The coal from this three mines are transported to SRP-CHP and SRP-OC, from here it is further distributed to various customers through rail and road network. All the above mentioned mines are operating; road network for transportation of coal is from existing mines to SRP-CHP, SRP-OC and also to NH-16 are well connected, the existing roads are used by SCCL authorities for transportation of coal. The same road network is used for the existing power plant. At present maximum quantity of coal is transported though rail network from SRP-CHP to other end users. For STPP, at present, Transportation of coal is being done through well-developed road network and also about 50% requirement of coal through rail network which was commenced on 01.08.2018. 2.2 Site Access The power plant and SCCL mines are well connected by existing village roads, state highway (SH 1 - Rajiv Rahadari) and national highway (NH 16) (Mancherial-Jagdalpur). The power plant is 500m away from NH-16 which is passing north side of the Power plant. The Hyderabad to Karimnagar state highway SH-1 is joining NH-16 around 5 Km west side of the power plant. 2.3 Status of Railway line SCCL has obtained the Rail Transport Clearance (RTC) from South Central Railway (SCR) for proposed private siding for M/s.
