EIA/EMP Hingula Washery (10 MTY) CHAPTER -1 INTRODUCTION 1.0 GENERAL Coal is an important infra-structural input and a dominant source of energy in India accounting for 54% of the country’s primary energy needs. The quality of coal plays an important role in environmental aspects during its use especially in power plants. Due to drift origin of Indian coal, ash content is quite high and coal seams have dirt bands of carbonaceous nature. High ash content in coal causes environmental pollution apart from reducing plant efficiency and adding the cost of coal transportation per unit calorific value. Further ash disposal is itself a difficult task with adverse environmental impacts, MoEF Gazette Notification, G.S.R. 02 (E) dated January 02, 2014 on coal supply to power plants located between 500-749 KM, 750-1000 KM shall be supplied with and shall use raw or blended or beneficiated coal with ash content not exceeding 34 % on quarterly average basis w.e.f June 05, 2016 and January 01, 2015 respectively while power plants located beyond 1000 kms from pit head shall be supplied with and use raw or blended or beneficiated coal with ash content not exceeding thirty four percent on quarterly average basis with immediate effect (i.e. Jan 02, 2014). Thus it is imperative that coal is beneficiated before use not only for value addition but also as environmental mitigation measures. A review meeting was taken by Honourable Minister of State (Coal) in January 2007 at CIL (HQ), Kolkata. In the review meeting, Coal India Limited (CIL) decided that all opencast mines with an annual capacity of 2.5 MTY or more, not linked to any pithead power house, should have provision for setting up coal washery with state-of-art technology. These proposed washeries are to be set up on Build, Operate & Maintain (BOM) concept. Keeping in view the above decision, MCL has intended to install 4 nos. of washeries in Ib Valley & Talcher Coalfields. Accordingly, MCL awarded the job for preparation of CR (Conceptual Report) for setting up of Hingula Washery at Talcher Coalfield on Build, Operate & Maintain basis to M/s Central Mine Planning & Design Institute Ltd. (CMPDI) vide letter no. MCL/ HQ/ 3206/ CP&P dtd 19.02.08. Thereafter, in the review meeting with Director (T), CIL held on 08.08.2008 at Kolkata it was discussed and agreed by all concerned present in the meeting that to expedite the works for setting up of coal washeries. 1.1 BRIEF DESCRIPTION OF THE PROJECT The proposed Hingula coal washery will be located in the lease hold area of Balram OCP of Hingula area of MCL and its capacity shall be 10.0 MTY. The proposed project will receive coal from of Hingula-II expansion OCP of Hingula Area, MCL. The raw coal ash content of Hingula-II expansion OCP is in the range of 38.5 ± 4%. This ash content is proposed to be reduced to 33.5 ± 0.5% after washing in Hingula Washery for use in thermal power stations. It is planned for two product namely clean and reject. Washed coal shall be transported from Hingula washery to the silo (4000t) near railway siding by 2x2000 TPH covered conveyor belts of length 400m. The reject from the washery shall be to be transported from washery to reject site (area 10ha) by I-1 EIA/EMP Hingula Washery (10 MTY) covered conveyor belt of length about 760m. In the 155th meeting of Board of Directors of MCL held on 05.022014, the Board approved the sale of rejects from Hingula washery of MCL either through e-auction or MOU route. This was in line with the 75th meeting of CMDs held on 07.05.2013 wherein it was decided that EOI shall be floated to sell the reject from the proposed washeries. The proposed washery shall be set up on Build, Operate & Maintain (BOM) concept. Build, Operate & Maintain (BOM)” concept refers to the system in which finance for setting up of plant will be made available by CIL/ MCL to the selected bidder as in the case of turnkey basis. The scheme envisages planning, design & engineering, selection of necessary equipment & machinery, procurement, delivery, erection/ installation, testing, successful commissioning of coal washing plant including PGT with two years’ critical spares and all allied activities as well as its subsequent operation & maintenance for supply of washed coal of requisite quality at the designated delivery places and disposal of washery rejects on BOM concept. Freedom of selection of efficient, cost effective and state of art technologies lies with the BOM operator. The BOM operator will be responsible to produce washed power coal with the quality specification laid down by MCL. However, ownership of raw coal fed to the washery & products of washery shall lie with MCL. BOM operator will be paid washing charges as per mutually agreed terms & conditions for operating & maintaining the washery till the entire contract period. The contract period for operation and maintenance for Hingula washery shall be 10 years. The washing of coal will lead to improvement in performance of power plant, reduction in particulate emission, reduction in load on Railway Network and reduction in handling and transportation cost of coal and solid waste. Customer for Washed Coal of Hingula Washery The prospective customer for washed coal & distance from washeries is given here under: Sl. No Prospective Customer Location (State) Distance (Kms) 1 TANGED Co. Tamilnadu > 1000 2 KPCL Karnataka > 1000 3 NTPC Andhra Pradesh 500-749 4 WBPDCL West Bengal 500-749 5 Sesa Sterlite Ltd Odisha < 500 6 GMR Kamalanga Energy Ltd Odisha < 500 7 Adani Power Ltd Gujrat > 1000 Rejects would be sold through e-auction or MoU route as it has gross calorific value in the range of 1000-2000 K Cal/Kg. Present Status The tender for setting up of Proposed Hingula Washery on BOM basis has been finalized. M/S Monnet Ispat and Energy Ltd.(MIEL)has been identified as L-1 bidder. I-2 EIA/EMP Hingula Washery (10 MTY) 1.2 PURPOSE OF THE REPORT The purpose of the EIA/EMP Report is to apply for grant of environmental clearance for the proposed Hingula Washery (10.0 MTY) from Ministry of Environment & Forests, Govt. of Indiain view of EIA notification 2006 dated 14th September’06. The proposal of terms of reference (TOR) was discussed in EAC meeting held on 13th December, 2013. Subsequently the Ministry of Environment & Forest, Govt. of India (MOEF) issued TOR vide letter No. J- 11015/67/2013-IA.II(M)dated 31-01-2014 for obtaining environmental clearance for Hingula Washery (10 MTY) of MCL. It is envisaged that the proposed washery will run as per the approved washing technology offered by M/s MIEL for washing raw coal @10.0 MTY.

The proposed site for washery is within the leasehold area of Balram OCP and in between OB Dump & Railway siding of APGENCO. Initially, land of 30 Ha (600m length & 500m wide) at Balram Opencast Project in Hingula Area was identified by MCL for the proposed washery. From the Surface Plan of Balram Opencast Project in Hingula Area, it is quite evident that a seasonal nallah is flowing through the proposed land. Moreover, a part of OB Dump is also falling under the identified area of proposed land. In light of the above, CMPDI team & MCL authorities jointly decided to ascertain exact area of usable land suitable for setting up of the washery with length & breadth excluding the seasonal nallah & part of the OB dump those were falling under the proposed land. Hence, the proposed site for Hingula Washery was finalized within an area of 17Ha, situated in the lease hold area of Balram OC Extension Project, which falls between latitudes 200 56’02’’ N & 20058’ 28’’ N and longitudes 85002’ 52’’ E & 85006’ 57’’ E. An I-3 EIA/EMP Hingula Washery (10 MTY) additional land of 10 Ha has been finalized for temporary storage of reject located at a distance of about 760m from the proposed washery site. The entire land for washery is non-forest, non-agricultural and is non-coal bearing. Land Use/ Cover Map of Core & Buffer Zones of Hingula Washery Project based on Satellite Data of the Year 2013 is enclosed as Plate no. 8 in the EIA/EMP report. Barren and scrubland of core zone 1.3.2 Communication Talcher is the nearest town located at a distance of 19 km from the eastern most boundary of Kalinga Block. The Talcher-Gopalprasad road passes through the central part of the area. The nearest rail-head is Talcher Railway station, which is the terminal station on Cuttack-Talcher branch line of East Coast Railway. The distance of the station is about 16 km from the eastern boundary of block. Distance of the National Highway no. 42 from the boundary is about 12 km by shortest route via Ambapal & Angul. New approach roads will be constructed in and around washery site for connecting it to the existing road network of the area for transportation of men and material.
