Air Pollution caused by dust emission from activities is controlled by good management practices like continuous water spray over the unpaved or bare surfaces, covering soil materials pile and by completing of the pavement of bare surfaces. Soil and water pollutions are also prevented by proper management like spill prevention and well drainage system. Solid waste is managed by the waste management plan. Noise pollution is also a regarding issue during generation of electricity. Noise level is reduced by proper traffic management system and using of environmental friendly high technology electricity generating units and auxiliaries where main generator and turbine is under canopy system with sound attenuation technique. Every personnel uses personal protective equipment to ensure own safety. The remarkable achievement in this period is that till now there is no record of accident or injury. APSCL is committed to keeping the accident level at Zero by implementing its proper occupational health and safety management system. This project also has a positive effect on the socio-economic condition. Local skilled and semi-skilled peoples are engaged in different levels of construction and operational activities and they are very happy for getting employment opportunities. 1 1.0 INTRODUCTION The objective of the environmental s a f e g u a r d management and monitoring is to record environmental impacts resulting from the project activities and to ensure implementation of the “mitigation measures” identified earlier in order to reduce adverse impacts and enhance positive impacts from specific project activities. Besides, it would also address any unexpected or unforeseen environmental impacts that operation phases of the project. The EMP clearly lay out: (a) the measures to be taken during both construction and operation phases of the project to eliminate or offset adverse environmental impacts, or reduce them to acceptable levels; (b) the actions needed to implement these measures; and (c) a monitoring plan to assess the effectiveness of the mitigation measures employed. Environmental management and monitoring activities for the under construction power plant project could be divided into management and monitoring: (a) during construction phase, and (b) during operation phase. The application of this plan involved an environmental control and monitoring of the work by a technical team to verify compliance with all the indications, limitations or environmental restrictions set forth in the Environmental Management Plan (EMP), EIA and the Project, with the minimize damage caused by work on the environment. The information obtained by the implementation of the Environmental Action Plan is required to define preventive measures or define corrective actions. The information generated as a result of implementing the Environmental Action Plan must be duly forwarded to the Department of Environment (DoE). 1.1 Brief Project Description A Combined Cycle Power Plant of Total net 450±20% MW capacity at site condition (35 ºC, 1.013 mbar, 98% R.H.) is installed by Ashuganj Power Station Company Limited inside the existing premises. The Power Station is connected with the Ashuganj 400 KV Gas Insulated Switchgear (GIS) Grid Sub- Station and also with Ashuganj 230 KV Gas Insulated Switchgear (GIS) Grid Sub-Station with necessary electrical equipment. The basic concept for the Ashuganj North project is a CCGT Plant based on one Gas Turbine Generator unit (GTG), one Unfired Heat Recovery Steam Generator and one Steam Turbine Generator unit (STG). Water-steam cycle is of three pressure levels (HP, IP and LP) with reheat. The Ashuganj 450 Mw (North) Combined Cycle Power Plant Project complex is located on the Southern bank of Meghna river, just outside and to the East of Bhairab Bridge. The power plant is located in Ashuganj under Ashuganj Upazilla. The entire p o w e r p l a n t is completely enclosed, covers an area of about 10.17 acres and is owned by the Ashuganj Power Station Company Limited (APSCL). 2 1.2 Project Progress Status and Implementation Schedule The basic concept for the Ashuganj north project is a CCGT Plant based on one Gas Turbine Generator unit (GTG), one Unfired Heat Recovery Steam Generator and one Steam Turbine Generator unit (STG).Water-steam cycle is of three pressure levels (HP, IP and LP) with reheat. General components of the CCGT project include the following: (i) 450 MW CCGT unit complete with necessary auxiliaries including air intake filtration facilities, inlet and exhaust silencers, control systems, bypass stack with delivery damper, gas fuel treatment system, (ii) Power generator for the gas turbine unit with all auxiliaries including cooling system, control system, excitation system; (iii) o n e Steam turbine unit complete
