The project will ensure that the LFG generated from the landfill is collected through a comprehensive network of gas wells and flared in a flaring system so that the GHG potential of the LFG is destroyed. The project will contribute to reduction of GHG emissions to the atmosphere. It will also improve landfill safety and eliminate the smoky environment which is often caused by spontaneous burning of waste in the upper layers of the landfill arising from release of LFG from the landfill. Implementation of this proposed CDM project activity is included as part of the investment package planned for the Solid Waste Management component of the World Bank funded Kampala Institutional and Infrastructure Development Project (KIIDP). The construction and operation of such plant has the potential to cause adverse impacts on the environment and the public health safety, if appropriate control measures are not taken. NEMA, the National Environment Management Authority of Uganda, has recently issued a license to KCC for purposes of carrying out improvements on the operations and management of Kiteezi waste disposal site. In the license, NEMA has mandated KCC to carry out an environmental impact assessment of the project it intends to implement under CDM and obtain approval of environmental aspects of the project from NEMA before implementing the project activity. The EIA report has been prepared in accordance with the Environmental Impact Assessment Regulation Act S.I. No. 13/ 1998 promulgated by the National Environmental Management Authority (NEMA) of the Government of Uganda. This act directs all projects covered under Schedule 3 of the National Environment Act, Cap 153, to undertake environmental impact assessment and approval there after from NEMA. Solid waste management activity is one of the activities covered under Schedule 3 of the National Environmental Act. Project The Mpererwe, Kiteezi landfill site is located in the Nangabo Sub-Country of Wakiso description District , 13 kilometres north of Kampala city center. Kampala is located in the south of Uganda, close to the northern shores of Lake Victoria. The site of the proposed project is a containment site and has been filled in with waste since 1996. Present size of the site is 29 acres and additional 6 acres plot was acquired on the south side for further extension of the life of the site by two years Geographically, Kampala where the project site is located is at following coordinates: Latitude : 2 50' 0'' Longitude : 32 34' 00'' Main features of the site are as follows: The site has smooth rolling terrain with hilly surrounding, especially on the south and east side. The average height of ground surface at the proposed project is about 1172 m above mean sea level. Area around the proposed project site in Wakiso District receives approximately 1000 mm rainfall annually. There is no archaeological monument or cultural property near immediate vicinity of the site. Kampala City Council 5 There are no endangered species of flora and fauna in the project area. Site is surrounded by habitation within 500 m, separated by a natural buffer zone of hillock or trees and bushes. One house is very close to site , just at the entrance. The house owner was landlord of part of the landfill site once upon a time and voluntarily sold part of his land to KCC for landfill development. Site Setting The site is readily accessible by the existing road network. The landfill site is located to the north of Kampala City about 13 km from the City Center. The present access to the site from Kampala City is through Kampala-Gayaza road (about 9 km), branching off to the left at Mpererwe and following the bitumen road going to Namulonge (about 4km). The site surrounding consists of grassland characterized by short grass with a few trees and shrubs. Entire eastern boundary is part of a wetland. The major hydrologic feature observed is a perennial stream in the valley bottom flowing South East. It flows through wetland with relatively thick vegetation and papyrus reeds adjacent to the site, to the walufumbe swamp.The general drainage pattern is semi-dendrite in nature forming a regional catchment area. Site drainage pattern is toward valley bottom which is on the South-East side of the landfill site Environment There is significant environmental setting around the project site. Site is not very Setting in far(500m) from habitation area in the immediate vicinity. One house owner, who was area also the land owner of part of the area, from whom KCC bought land for the present site under consideration, is located just at the entrance of the landfill site on south direction. Eastern boundary of the landfill is just on the edge of wetland with swamp. Soil erosion is evident at this location owing to soil excavation activity for construction of Leachate Treatment Plant.
