General Introduction: An Environmental Management Plan (EMP) has been prepared which covers source of pollution and their proposed pollution control measures formulated on the basis of the survey undertaken. The industrial development in the project area needs to be intertwined with judicious utilization of natural resources within the limits of permissible assimilative capacity. The assimilative capacity of the project area is the maximum amount of pollution load that can be discharged in the environment without affecting the designated use and is governed by dilution, dispersion and removal due to natural, physiochemical and biological processes. The Environmental Management Plan (EMP) is required to ensure sustainable development in the area of the said project of M/s Dr. Mittal Laboratories Pvt. Ltd. Hence, it needs to be an all encompassive plan for which the proposed industry, government, regulating agencies such as, State Environment Impact Assessment Authority, Pollution Control Board working in the region and more importantly the affected population of the project area need to extend their cooperation and contribution. At the industry level pollution control measures include in built processes control measures and also external control measures at the end of pipeline before they are discharged into the receiving bodies. The project is likely to provide new economical fillip to the area. The Management Action Plan aims at controlling pollution at the source level to the possible extent with the best available technology followed by treatment measures before they are discharged. Various impacts due to proposed project both during construction and the operation stage of the project have been assessed. In order to ensure a sustainable development in the region of the proposed project site, suitable mitigation measures shall be taken up. The mitigation measures shall be both at the source and end of the pipeline stage. In addition, optimum utilization of resources and adoption of low and non-waste technologies in the process shall be adopted as much as feasible in order to achieve waste minimization and optimum utilization of the raw material. Environment Management Plan (EMP) is required to be implemented by the plant management in order to achieve better environmental viability of the project during the operational phase. In EMP all technical, biological and socioeconomical control measures have been envisaged and these pertain to: 1. Water requirement and supply system 2. Waste water treatment technology 3. Solid waste management 4. Air pollution control 5. Afforestation and landscape development 6. Fire fighting system - 2 -
7. Corporate social responsibility 8. Corporate environmental responsibility 9. Income generation opportunity 10. Improved working conditions Water requirement and supply system: The total water requirement for the project is 3.25 KLD. The water will be sourced from Groundwater through deep bore well. Necessary permission will be obtained from CGWA. Waste Water Treatment Technology: About 25 persons has to be employed in the proposed project. So, 1.25 KL of domestic waste water will be generated which has to be treated through a Septic Tank and Soak Pit. A septic tank is a horizontal continuous flow type of a sedimentation tank, directly admitting raw sewage and removing about 60 to 70% of the dissolved matter from it. The effluent from such a tank will be sufficiently foul in nature and will have to be disposed off either for sub surface irrigation or in cess pools or soak pits, before disposing it of in water courses. The sludge settled at the bottom of the tank and the oils & greasy matter rising to the top surface of sewage as scum are allowed to remain in the tank for a period of several months, during which they are decomposed by the anaerobic bacteria to form gases and liquids by the process of sludge digestion. The resultant sludge so obtained, will consequently be less then that obtained in ordinary setting tanks (the quantity is reduced because of digestion).the digested sludge from the tank is periodically removed and taken to a nearby sump, from where it may be pumped upto to the ground and disposed off in a sanitary manner, preferable after drying it. While designing the septic tank, the following factors are being considered. 1. Capacity of Septic Tank 2. Inlet & Outset baffles 3. Detention Period 4. Length to Width Ratio The size of this tank will be 2.5m X 2.0m X 2.0m with proper baffle walls and inlet and outlet provisions. Effluent received from septic tank will be taken into soak pit. A soak pit is circular covered pit, through which the effluent is allowed to be soaked or absorbed into the surrounding soil. The soak pit will be filled with stone aggregate and some part may be kept empty. When the soak pit is empty, the pit is lined with brick, stone or concrete blocks with dry open joints. In addition to this, this lining is supported below the inlet level by at least 7.5 cm thick backing of coarse aggregate. The lining above the inlet level should be plastered with cement mortar. However when the soak pit is filled with stone or brick aggregate, no lining is required except for a top masonry ring constructed to prevent damage by flooding of the pit by surface run off. - 3 -
The soil of this area is highly porous with proper percolation hence soak pit is the one of the best solution for the domestic waste. Process Waste: The water consumption and waste water generated from the proposed project is given below. Table No. 1 Water Consumption and Waste Water Generation Sl. Water Consumption Waste Water Source/ Head No (KLD) Generation (KLD) 1 Process 1.9 1.5 2 Domestic 1.25 1.0 3 Floor Washing 0.1 0.00 Total 3.25 2.5 Generation of Wastewater: The waste water is generated because of following factors; Accidental or intentional spillage s Dripping allowed escaping into the water Washes containing alkali and other chemicals used to remove dust from vessels. From the process of liquid syrup. Though flow rate of waste is very less but we are planning to have an ETP to cater the waste water up to 2 KL. Quantity & Characteristics of Effluent : Waste Water flow (max) = 2.00 KL/day BOD = 205 mg/l COD = 300 mg/l Total Suspended Solids = 350-900 mg/l ph = 7.5 9.5 Oil & Grease = 90 mg/l Proposed Treatment Scheme: Collection of Effluent Neutralization of Effluent Oil & Grease Separation Absorption Sludge drying beds - 4 -
The treatment of effluent when viewed from environmental angle, following units are required in series. Collection cum Equalization Tank: Makes the flow uniform with respect to suspended solids dissolved in it. Effluent is chemically treated here to maintain the ph and also to avoid the septic nature. Oil & Grease Tank: Oily and greasy impurities may take place because of preparation of medicine. In this tank this will be trap and removed in a container manually. Reaction cum Tube settler: In this tank aeration and clarification takes place and effluent sent to DMF. Dual Media Filter: In this tank effluent is filtered and sent to clear water sump for irrigation purpose. Sludge Drying Bed: Solids from collection cum equalization and reaction cum tube settler will be dried in sludge drying bed. The filtrate from the sludge drying beds progress to collection tank. The dried sludge is disposed through TSDF. Process Flow Diagram of Effluent Treatment Plant is given below. Figure No. 1 Process Flow Diagram of Effluent Treatment Plant - 5 -
Solid & Hazardous Waste Management: Soil will be generated during construction and the generated soil will be reused for land leveling and as subsurface material during road making inside the premises. Solid waste generated from sludge drying beds of ETP shall be disposed to TSDF as per the norms of State Pollution Control Board. Used oil shall be disposed to authorized recycler. Expired drugs shall be disposed as per the norms of State Pollution Control Board. A Forestation and Landscape Development : The implementation of greenbelt development shall be beneficial to the biological environment. Plan ts will be planted in two or more rows depending upon the availability of the space. However, in 33% of the total project area, the green belt is to be developed using such plant species, as are having the following characteristics: Pollution tolerant species Fast growth rate Thick green foliage cover Evergreen Indigenous or which could be easily grown. Ecologically compatible Source of Emission & its Mitigation Measures: Emission from DG Sets: One number of DG set of capacity 62.5 KVA equipped with proper acoustic enclosure and suitable stack height is provided as a standby measure during power failure. Fugitive Emission: Frequent water spraying would be done in the open area to keep the SPM contributed by the traffic movement at a low valley. Plantation: Planting trees inside the project along the roads will act as sink for dust. Rainwater Harvesting Plan: Rain Water Harvesting is collection and storage of rain water for suitable uses. For rain water harvesting, water is captured and stored either above the ground or used as to recharge the ground water to be used later on. The Rain Water Harvesting System shall consist of seepage/percolation pits. The Rainwater shall be diverted from the rooftop using rain water pipes to the rainwater harvesting system. Proper precautions will be taken to ensure that rain water collected is free of any pollutants. - 6 -
The rain water harvesting system will be set up to sustain ground water table by recharging the aquifer. Fire Fighting System : A comprehensive fire- fighting system is proposed containing fire hydrant system, fire water tank, fire water pump, jockey pump. Fire extinguishers are also proposed as approved by fire department. Sand Buckets for fighting shall be provided in sufficient numbers in whole of the plant. Proper use of Personal Protective Equipment (PPE) like helmet, goggles, safety shoe, ear plugs, musk, etc. is being assured. All electrical equipment and machinery will be properly grounded. Control switches will be properly located at the point of operations best suited to control the equipment. Informatory hoarding will be displayed to handle the by chance situations. Information for good housekeeping will be displayed. Supervisors and employees will be properly trained to operate power Equipment or machinery and also in their safe operation. An Effective communication system will be practiced in case of any un favourable conditions. Corporate Social Responsibility: The social management plan will be designed to take proactive steps and adopt best practices, which are sensitive to the socio-cultural setting of the region. Corporate- Environmental Responsibility: Main objectives of environmental policy are as following: Comply with all applicable environmental laws, and other commitments, with the objective of moving beyond compliance to create shareholder and customer value; Take a risk management approach addressing the adverse environmental impacts of our operations-first, prevent pollution, where feasible and economically sustainable, then environmental impacts that cannot be avoided; Utilize natural resources more efficiently; Engage employees towards energy efficient products; Measure and publicly communicate the progress being made towards improving environmental performance and independently verify key performance results; Industry is committed to responsible waste management and aim to reduce, reuse and recycle waste generated through premises by: Reviewing and improving our working practices Building effective waste management and awareness into the decision making process. - 7 -
Delivering effective waste management information to all employees. Income generation opportunity: Local manpower would be given preference, although they would be recruited on their own merits. Specific consideration would be given for the employment of locals from neighboring areas. Improved working conditions: The project will provide safe working conditions for the workers employed at the facility. Conditions of additional employment address issues like minimum wages for the workers. Action to be taken in case of Disaster: Provision of an Audio Alarm Immediately in case of disaster the following authorities will be alerted The District Magistrate Chief Medical Officer Superintendent of Police Fire Station Nearest Police Post All people who do not required First Aid in the plant, will be immediately evacuated. All people who required First Aid will be given First Aid and then taken immediately to the hospital. - 8 -
