AUTHORS’ SUMMARY The Environmental Impact Assessment Statement (EIAS) on the completion of construction works for Luda Yana Dam has been developed following the submission of the comprehensive Environmental Assessment ( ) of 2007 to the World Bank by the Ministry of regional development and public works (MRDPW). It is a part of the documentation for approval of the World Bank assistance requested by the Government of Bulgaria (GoB) for financing of activities meant for municipal infrastructure development through completion of the water supply dam Luda Yana. The EIAS has been developed to meet the Bank requirements as stated in the ToR and in compliance with the effective environmental legislation in the Republic of Bulgaria (RB). It comprises the following major elaborations and findings. Overview of the legislative and political system and organizational diagram referring to the environmental management Environmental protection is a country policy priority. Depending on the classification of infrastructure projects they can be either subject to a mandatory EIA or subject to an assessment of the need to have an EIA. Luda Yana dam, which has a total volume of 19,94.106 m3 is subject to a mandatory EIA (Appendix 1 to the Environmental Protection Act – EPA). The EIAS presents the normative documents of the RB that have to be complied with in the course of work, as well as those required by the Bank. The organizational diagram referring to the environmental management is also presented. Luda Yana Dam Project The construction of Luda Yana dam started in 1986 and the implementation continued throughout the years in compliance with the technical detailed designs (following the design stages effective in those years) until its suspension in 2000. The design has been developed in line with the effective regulations with regard to the security and safety of the dam wall and the facilities thereto. In 2007, based on a contract with Vodosnabditelen complex OOD, town of Panagurishte, a Comprehensive feasibility study for continuation and completion of construction works for Luda Yana dam - Panagurishte was prepared. This paper secures the implementation of some of the requirements stated in the EA of 2007 for evaluation of the existing situation and the performed construction, updating of hydrological information and the required additional developments for the site. Environmental Status The status of the environment has been evaluated based on inspection of the territory, field research, review of the available data at bodies with competencies in environmental management – the Regional Inspectorate of Environment and Water (RIEW)
