AUTHORS’ SUMMARY The Environmental Impact Assessment Statement (EIAS) on the completion of construction works for Neykovtsi Dam has been developed following the submission of the comprehensive Environmental Assessment (ЕА) 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 Neykovtsi. 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. Having a total volume of 4,80.106 m3 Neykovtsi dam does not fall under the requirement for a mandatory EIAS (Appendix 1 of the Environmental Protection Act – EPA), but is subject to an assessment for the need to perform an EIA. The EIAS for Neykovtsi dam has been developed in compliance with the Terms of Reference (TOR) of the Bank in coordination with the Ministry of Environment and Water of Bulgaria. 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. Neykovtsi Dam Project Construction of Neykovtsi dam was launched in 1978 but it was put on hold several times and finally terminated in 2001. The dam wall and the adjoining facilities, as well as the Drinking water treatment plant (DWTP) were implemented following the developed technical detailed designs (according to the design phases effective in those years). The designs have been developed in line with the effective regulations with regard to the security and safety of the dam wall and the facilities thereto. The designs of the dam wall and of the DWTP are to be updated, following a preliminary evaluation of the quality of the performed construction seven years after its termination. 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) in the town of Veliko Tarnovo, literature, survey data etc. The status of the environment in the area of Neykovtsi Dam is impacted by the construction works
