On amendments to the Decree of the RF Government
of September 15, 2020 No. 1430 (for discussion)

Summary

An example of regulating process indicators of pollution discharge by public wastewater disposal system facilities is given. The attention is focused on the following issues: process indicators of the EU countries and Russia, regulations for a high-water intake of Siberia, the impact of anthropogenic load on the surface runoff in large cities. Of particular note are the nuances of comparing process indicators of the best available technologies and the cost-effectiveness of their achievement for the upgraded facilities. The established low indicator for suspended solids practically determines an increase in the required volumes of «aeration tank-sedimentation tank» structures or a significant decrease in the output of the existing treatment facilities, or the construction of tertiary treatment facilities. The former principle of accounting for the process capability of the existing facilities while establishing standards for the permissible pollution discharge and corresponding indicators of standard water protection technologies is considered. The feasibility of improving the established process indicators for suspended solids, ammonium nitrogen and phosphorus as phosphate for the upgraded treatment facilities is shown taking into account the regional specific features of the anthropogenic load on the receiving water.
