Environmental Management Plan

Transcription

1 Environmental Management Plan 1. OBJECTIVE The objective of Environmental Management Plan (EMP) is to formulate which will: Mitigate adverse impacts on various environmental components, which have been identified during the rapid environmental impact assessment study. Protect environmental resources where possible. Enhance the value of environmental components where possible. EMP also includes a monitoring plan to enable evaluation of the success or failure of environmental management and to carry out reorientation of the plan if found necessary. It is emphasized that many of the protective and enhancement can be implemented by adopting suitable planning and design criteria for construction of the project. The following have been suggested after discussion with project proponent. 2. LAND ENVIRONMENT 2.1. Traffic Management Construction Phase The proposed site is in a developed area. There are existing access roads to the site. Internal road layout for traffic management within site has been designed. Special care will be taken during transportation of construction material like cement, sand, aggregate etc. as considerable quantities of such material would be transported from various material suppliers. The material will be sourced from the nearest available government approved contractor. Since road transport is unavoidable, such movement will be during non- peak hours as far as possible. Operation Phase The impact on land environment during operation phase will be due to movement of vehicles of users and visitors to the site. Precautions that will be taken to minimize impacts of traffic will be as follows: Development will be as per local guidelines for residential development. There will be minimum amount of cutting and filling. Earthwork will be primarily for creation of foundation and basement. Part of this will be used onsite as filling material and remaining will be disposed outside the site. Adequate provisions will be made through provision of internal roads for smooth vehicle entry and exit. Approach road (external road) and internal roads for onsite traffic movement will be planned as per project development. 2.2 Solid Waste Management Please refer Annexure III for details on Solid Waste Management The salient features of the proposed solid waste management strategy are as follows:

2 Construction stage During construction stage, labour camp for about 15 labourers would be provided with solid waste management facilities. Solid waste generated from labour camp would be segregated and collected in separate bins for non-biodegradable and biodegradable waste. Non-biodegradable waste will be disposed by selling to scrap dealers (recyclable) and to existing authorized agency (inert and non recyclables). Biodegradable waste will be treated on site in vermin-composting pits and compost will be used for landscaping on site. Demolition waste and construction waste would be generated which would include debris, concrete, steel and other metals, bricks, pallets, packaging and paper products, railings, door and window casings, fixtures, tiles, furnishings etc. For waste generated during the construction phase, gross segregation of the wastes into roadwork materials, structural building material etc. would be made. Additional segregation to facilitate reuse/ recycling would be made. Material wastes like bricks, cement etc. will be used as fill material and concrete would be recycled and reused at the site. Adequate facilities for the storage of these waste materials would be made on site. Operation stage Management of solid waste generated during the operation phase would include collection, transportation and disposal in a manner so as to cause minimal environmental impact. It will be made mandatory for waste to be segregated right at the source of waste generation. There would be manual collection & storage of biodegradable waste; and reusable and recyclable waste would be manually collected and stored in closed rooms at ambient temperatures. Biodegradable waste from residential buildings and club house would be transferred to mechanical composting units within the site for disposal. Compost from the same will be used for landscaping. Reusable and recyclable waste will be disposed by selling to scrap dealers and private contractor for resale. Non-degradable waste will be transferred to municipal solid waste management system. 3. AIR POLLUTION Construction Phase: a) Mobile source emissions: 1. Transportation of raw materials required for construction will be carried out during non-peak hours. 2. Idling of delivery trucks or other equipment will not be permitted during unloading or when not in active use. 3. To minimize dust emissions due to trucks carrying cement, gravel, sand to site, ready mix concrete carried in enclosed container will be used which is a better option as compared to on site batch mixing. 4. Dust covers will be provided on trucks used for transportation of materials prone to fugitive dust emissions. 5. Covering scaffolding equipment and cleaning of vehicles to be carried out to reduce dust and vapor emissions.

3 b) For stationary source emissions: 1. Most of the machinery related to construction will be located close to construction area for ease of handling. Machinery such as conveyers and mixers will be screened with sheets of suitable material to reduce transport of suspended particulate matter and noise. 2. All stationary construction equipment will be located as far away as possible from sensitive receptor locations in order to allow maximum dispersion of emitted pollutants. 3. Areas prone to fugitive dust emissions due to activities such as excavation, grading sites and routes of delivery vehicles across patches of exposed earth, will be frequently water sprinkled to prevent re-entrainment of dust. 4. Hosing down road surfaces especially if they are unfinished surfaces will be carried out to help to prevent fugitive dust emissions. 5. Other to be taken will include appropriate containment around bulk storage tanks and materials stores to prevent spillages. 6. Apart from these, equipment/ machines and vehicles will be always kept in good state of repair to minimize emissions. Construction areas will be enclosed, wherever possible. Operation Phase 1. Plantation along the roadside will help to reduce effects of air/ noise pollution. A row of trees will be planted along the plot periphery to screen the site from air/ noise pollution. 2. Regular maintenance and upkeep of the internal road within project will ensure smooth traffic flow and will help to reduce air pollution. 3. As per the project analysis, the impact of proposed project would be positive when proper traffic flow is maintained. The entrance/ exit to the site will be maintained so that there are no obstructions to traffic flow. 4. NOISE POLLUTION Construction Phase 1. Contract specifications for construction work will specify use of noise generating equipmentgenerating noise of not greater than 90 db (A). 2. Construction specifications will also stipulate levels of maximum noise generation in various zones based on CPCB Noise Standards. 3. High noise generating construction activities like, compacting etc. will be carried out only during daytime. 4. Workers working near high noise construction machinery will be provided with ear muffs/ earplugs. 5. Provision of temporary barricading around site will be carried out. Operation Phase During operation phase, it is important to maintain the noise levels within the plot for the safety and better health of laborers. Various precautions to be taken to maintain acceptable noise level within the project area are as under: 1. Buffer in form of wall or tree plantation will be provided along the main roads.

4 2. Smooth flow of traffic will be ensured on the internal road to avoid idling of vehicles. 5. WATER ENVIRONMENT Construction Phase: 1. Construction area will be isolated and care will be taken to divert the run-off to storm water drainage, so possibility of pollution from construction run-off is prevented. Also, subsurface work will be carried out only during non-monsoon period. 2. Precaution will be taken to ascertain that no waste material like cement, paint and solid material like iron rods and any other material is dumped into storm water system. 3. No accumulation of stagnant water will be allowed to prevent breeding of mosquitoes. 4. Labour camps will be provided with septic tank and soak pit arrangement for waste water treatment. Operation Phase: 1. A well-engineered storm water drainage system will be provided as a part of this development. 2. Due to proposed Rain Water Harvesting there will be a positive impact on ground water regime due to proposed project in the operation phase. Rain water from the roof will be transferred to separate Rain Water Tank via network of chambers/ piping. Before entering the tank, it will pass through coarse filtration. This water will be transferred to main UG tank by suitably filtering it. 6. GUIDELINES FOR BIO-AESTHETIC MANAGEMENT At present there are no existing trees on site. As part of the proposed development, a well designed landscape plan is proposed. Trees will be 1 tree for 100 sq.m. of plot area. 6.1 Species Recommended for Plantation The basic thrust for plantation will be on ecological value followed by aesthetic value of the tree. Local species which support local biodiversity will be planted within the green areas. List of suggested trees species Sr. No. Scientific Name Common/ Local Name Family Habit 1.
