Ecological justification of design decisions related to the use of water resources for hydropower deployment of recently acquired particular urgency in connection with the failure of development section of the draft Impact Assessment (EIA). Under the existing regulatory and legal acts of the EIA documents to substantiate investment is sufficiently extensive material that is not fully respected and worked out. The article presents the shortcomings in assessing the impact of the proposed activity on the environment, identified on the basis of analysis of the project materials to deploy hydropower facilities on the mountain rivers.
Russian environmental legislation, despite the abundance of regulations, not regulated mechanism for the implementation of environmental activities in a market economy. In such circumstances, is particularly urgent task of addressing the problems associated with the possibility and permissibility of the use of natural resources and prevent the threat of environmental risk in major projects. The concept of the impact assessment (EIA) procedure and evaluation of environmental impacts at different stages of implementation intentions are vague and undefined, and not clearly tied to the stages of design.
An integral part of environmental studies at placing hydropower is environmental impact assessment of hydraulic engineering on all bodies of water zone of influence of HPS. This fact is especially relevant for the conditions of interbasin redistribution runoff. To achieve this, research carried out, the main tasks are: assessment of owls belt status of water quality of rivers in the region, forecast technological changes in the quality of natural water due to the promising development of the region and the commissioning of hydroelectric complex, the development of recommendations for water conservation measures, including including a rationale for sanitary and environmental flows.
