Government of Japan approved the request for project financing in November 2006. JICA conducted a Preparatory Study and concluded the Scope of Works in March 2007. The main counterpart agencies for this project are: the Ministry of Transport and Communication, the Ministry of Environment and Physical Planning, Skopje city and Public Enterprise “Water Supply and Sewerage” Skopje (Vodovod). "The Study for Wastewater Management in Skopje in the Republic of Macedonia" has commenced in September 2007 and is scheduled to be completed in May 2009. The main objective of the Study is to improve the water quality of the River Vardar in Skopje valley area. The Study is implemented in two phases: Phase 1 has completed in February 2008, and is followed by phase 2. The report of Phase 1 contains sewerage basic plan and wastewater management plan in domestic and industrial sectors, selected priority projects and includes capacity assessment on organization, institutional, financial aspects of Public Enterprise “Water Supply and Sewerage” Skopje (Vodovod) and on industrial wastewater management and water quality monitoring system. Preparation of the Feasibility Study started in May 2008 and it should be completed by November 2008. The Feasibility Study includes construction and proposed type of technology of the Wastewater Treatment Plant (WWTP) for city of Skopje and installation of the main collectors on both river banks (left and right),as well as siphon. The planed installations are required to comply with current EU and Macedonian legislation including the EU Urban Wastewater Treatment Directive (91/271/EEC). Environmental Impact Assessment Regulations enacted in Macedonian Law on Environment (Official Gazette no. 53/05; 81/05; 24/07) under the EU Directive on Environmental Impact Assessment (85/337/EEC) came in force in May 2005. The Law and complementary regulations stipulate the type and scale of development that are subjected to an Environmental Impact Assessment (EIA). In regard to the mentioned regulatory acts, EIA is required for Wastewater Treatment Plants that have a capacity in excess of 10,000 Population Equivalent (P.E.). As the capacity of the WWTP for Skopje is more than 500'000 P.E., preparation of the EIA is required. As a first step in conducting of EIA, Initial Environmental Examination Report was prepared during Phase 1 (Basic Plan) in February 2008. The purpose of this report was to identify and describe the regulations and guidelines governing the conduct of the EIA, baseline environmental data (water and wastewater management, protection of sensitive areas, protection of endangered species, land use, etc.), results of preliminary assessment of impacts, mitigation and monitoring plan. In June 2008, Consultancy company Tehnolab Ltd Skopje was selected to conduct EIA according to the JICA’s Guidelines for sub-contracting. This EIA Report is prepared on the basis of the results gained by the Initial Environmental Examination Report and scoping procedure which have been undertaken by the Ministry of Environment and Physical Planning and presents the finding on the Scope of Works defined in the Term of Reference for the certain activity, developed by the JICA Study Team, presented in Annex 1. October, 2008 1 Part II: A6-46 Tehnolab Ltd.—Skopje EIA Study WWTP, Skopje The preparation of the EIA Study has been conducted and prepared in accordance with National legal frame and EU related directives as well as “Sectorial EIA Guidelines–Waste Water Treatment Plant and the JICA’s Guidelines for Environmental and Social Considerations. The EIA addresses the following issues: Analysis of Guidelines, Policy, Legal and Administrative Framework Description of the Proposed Project Collection and Analysis of Baseline Environmental Data Analysis of Alternatives Identification and prediction of Impacts Preparation of Environmental Management Plan (includes mitigation, monitoring, capacity development and training, implementation schedule, risk analysis/contingency plan). The Report is presented in two volumes: Main Report and Annexes.
