Terms of Reference for EIA Studies Terms of Reference Kesare Executive Summary Mysuru also known as Mysore, is the third largest city in the state of Karnataka, India, which served as the capital city of Mysore Princely Kingdom (Kingdom of Mysore) for nearly six centuries, from 1399 until 1947. Located at the base of the Chamundi Hills about 146 km (91 mt) southwest of the state capital Bangalore, it is spread across an area of 128.42 km2(50 sq mt). The city has been divided into 65 municipal wards and the approximate population is 920550 (2011 Census) Municipal Solid Waste Management (MSWM) is an obligatory function of the Urban Local Bodies (ULBs) under the Karnataka Municipalities Act, 1964. Also, the Municipal Solid Waste, (Management and Handling) Rules, 2000 (“MSW Rules”) made it mandatory for an Urban Local Body (ULB) to practice sanitary treatment and disposal of the MSW generated. The estimated quantum of MSW currently generated in the city is approximately 402 MT. MCC has been carrying out collection and transportation of MSW in the city by deployment of its own resources and through private operators. A compost facility of 200 TPD capacity was also set up for treatment of MSW in the year 2001. The operations of the facility have however been intermittent over the past few years. However the compost plant even after augmentation of the bed by 200 TPD is receiving waste of about 150 TPD due to lack of infrastructure facilities and compost bed area. A sanitary landfill exists to the Eastern side of the compost processing plant. However currently there is a lack of handling 250 TPD of waste that is directly finding its place as a dump within the Sewage farm area. There is a gap in the primary and secondary collection system. Adequate tools and equipment for ZWM units are provided. Capacity of the existing compost facility at Sewage Farm is increased by providing adequate windrows platform, shed for windrows platform, leachate drain etc., The Mysore City Corporation is willing to improve its solid waste Treatment and disposal facility in lines with MSW Rules 2000 for a minimum design period of 20 years. This is an in-house Report. Based on the site analysis and secondary data analysis, it has been proposed to develop an integrated system for treating the municipal solid waste. It is proposed to have mechanical and partial manual ways of separating the waste into inserts, combustible waste and compostable waste. The biodegradable waste will be stabilized using windrow method for Terms of Reference for EIA Studies 28 days and further curing of 14 days there by converting the waste into compost which will meet FCO standards. The best possible recyclables like PET bottles, metal, HDPE/LDPE plastics will be recovered and sold to market. The combustible waste like cloth, paper, plastic covers, twigs etc. will be converted to fuel. The inerts like silt, stones, soles etc. to be landfilled using scientific methods at sewage farm. An administration office block with laboratory facility to test leachate, compost quality and calorific value of RDF will be facilitated within the site. A block for bathing and toilet facility for 40 workers along with dining room is made provision in the site. A workshop for cleaning of secondary and insitu vehicles is proposed with two washing bay at a time, repair bay for two vehicles and store room. Rain water conservation is proposed to ensure optimum utilization of natural resources. A zero discharge plant with an efficient leachate treatment facility is proposed where in the effluent will be recirculate for watering the landscaped area. An over cost of Rs. 2302.00 lakhs is estimated for Development of MSWM Facility at Mysuru. Project Description The project site area is located at survey no. 308, 309, 317 A, B C, D at kesare, Kasaba Hobli, Mysore. The site belongs to Mysuru City Corporation. It is located at 12 kms from the Mysuru central bus stand and the nearest railway station is at 6 km The site is isolated with no habitation till 1 km of radius area. The dense habitation is at Kesare from the Plant. The project site is presently utilized for solid waste processing facility and animal waste dumping. Terms of Reference for EIA Studies Note : The above values have been calculated based on the assumption that the intake of MSW (200 TPD) . The Design for development of scientific landfill site is as given below as per MSW Rules. The basic details of the site is as given below. Basic details about the landfill site Component Details Location Maragondanahalli (Bangalore) Inert waste proposed for dumping 200 tons per day (current) Terms of Reference for EIA Studies Topography undulating Subsoil Hard soil Average total precipitation 860 mm per year A suffocated leachate treatment unit will be provided with SBR and anaerobic system. The landfill has been designed with below details. The landfill will be provided with the following infrastructure. 1. Storm Water Drain: A RCC drain will be provided all around the landfill to capture the surface run off and reduce leachate generation. 2. Anchoring trench: An anchoring trench will be taken up where ever possible or a Cement plinth will be constructed with EGROOVE system for liner fixation 3. Liners provided: The cross section , bottom liner system is as given below. Once the formation is done, SLF is developed for Phase I initially for 2.5 years life. Liners are laid on the bed of the SLF and on the side slopes suitably fixed in the anchoring trench using available earth. Initially 150 mm thick PCC (1:4:*) is to be laid over which 200 mm of Cement Concrete M 25 to be laid. Over this layer after proper curing period, layer of 1.5 mm thick geomembrane, 300 mm drainage media and 200 GSM woven geotextile to be laid. The HDPE liners are welded suitably with welding machine to make SLF leak proof. All the membranes are anchored in the trench provided. Cross section of bottom layer of SLF Terms of Reference for EIA Studies Layers at side slope 4. A Leachate treatment plant will be constructed to treat the water and recycle the same for landscaping, washing and toilet flushing system. This project will augment the scientific disposal facility for BBMP. These landfills will be used in case of emergency too to tackle the garbage crisis. Phase wise development of Landfill site Once phase I is designed for filling the Quarry up to ground level and Phase II above ground level including rock next to the Quarry. The life of Phase I is 2.8 Years and Phase II is 2.2 Years. The phase III and IV will be developed in later stages once the waste fill will reach ground level.
