What materials should be prepared for environmental protection acceptance in the water storage stage of newly-built hydropower station project?

(1) Check the change of project construction content.

A permanent buildings: main economic and technical indicators such as dam site, normal water level, installed capacity, water diversion mode, hub layout, flood, demolition and resettlement; Cycloid and length of access road, location and scale of permanent camp, location (scale) and delivery method of power transmission and transformation;

B. Temporary land: the quantity, location and scale of temporary land occupied by construction camps, borrow and spoil sites and slag yards;

(2) Check the change of construction scheme.

Conformity of construction scheme with EIA and approval documents.

2. Ecological environment impact

(1) Ecological sensitive area. Focus on checking the implementation of ecological protection requirements in nature reserves, scenic spots, ecological functional areas, wetlands and other areas, the protection of ecological protection areas and protection targets delineated after the EIA document is approved, and the protection work plan after water storage.

(2) Implement terrestrial biological protection measures. Focus on the protection of national and local key protected animals and plants, local endemic animals and plants, regional endemic populations, ancient and famous trees and so on. In the flooded area and within the scope of construction.

(3) Implementing measures to protect aquatic organisms. Focus on the implementation of measures such as fish crossing facilities, fish proliferation and release stations, habitat protection and corresponding capacity building required by the EIA approval.

(4) Implement the downstream ecological water security measures. Focus on the implementation of measures to alleviate the impact of initial water storage on the downstream, the construction of downstream ecological water safety facilities, and the feasibility of ecological water safety schemes; For reservoirs with stratified water temperature, the rationality of the construction and measures of low-temperature discharge mitigation facilities should be verified.

(5) Implement soil erosion prevention and control measures. Ecological restoration of temporary land such as borrow (slag) yard, material yard, contractor camp and construction road.

3. Pollution prevention and control

(1) The construction, operation and operation effect of pollution prevention facilities for various environmental factors during the construction period, and the implementation of relevant pollution prevention measures.

(2) Influence of construction waste water, dust and noise on environmentally sensitive targets during construction.

4. Social shock

(1) The environmental rationality of the site selection of the centralized resettlement area for migrants' relocation and the implementation of various environmental pollution prevention measures.

(2) Rationality of site selection and implementation of environmental protection measures for production resettlement, enterprise relocation and reconstruction projects (such as highways and railways).

(3) Implement landscape and cultural relics protection measures.

5. Clean the bottom

Formulation and implementation of environmental protection scheme for bottom cleaning. On the basis of reviewing the special acceptance report of bottom cleaning, it is mainly to review whether the relocation of polluting enterprises and the disposal of hazardous wastes conform to the Design Code for Bottom Cleaning of Hydropower Projects (DL/T538 1-2007) and the national environmental protection requirements.

6, the main project operation plan

Whether the power generation operation scheme meets the environmental protection requirements such as ecological flow discharge, downstream water level fluctuation and water temperature change.

7. Environmental management

Implement environmental management, monitoring and research plans during construction. Focus on the rationality of monitoring points and section settings during the construction period, and whether environmental pollution or ecological damage events occur during the construction period.

8. Public comments

Public environmental complaints during construction period and their handling.
