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.

On the regulation of surface runoff handling
Summary
An analysis of a number of amendments included in the current version of CP 32.13330.2018 «SNiP 2.04.03-85 Sewerage. Pipelines and wastewater treatment plants», in terms of designing systems for the surface runoff disposal and treatment, as well as possible options for regulating surface runoff discharges into public wastewater disposal systems and water bodies, taking into account the requirements of the current environmental legislation is presented. An assessment of the effect of the negative environmental impact category of the enterprise on the regulatory requirements to discharged wastewater is given. It is shown under what conditions and under what category it is advisable for an enterprise to operate its own surface runoff outfall to a water body or discharge wastewater into a public sewer.

Experience of SUE «Vodokanal of St. Petersburg» in eliminating HELCOM hot spots in the light of the development of the Russian environmental legislation
Summary
The activities implemented by SUE «Vodokanal of St. Petersburg» to fulfill the recommendations of the Helsinki Convention on the protection of the Baltic Sea against pollution are outlined. The work completion stages on eliminating the discharge of raw wastewater into the Gulf of Finland, upgrading and reconstructing the treatment facilities, and improving the efficiency of wastewater treatment are described. The measures taken provided for almost eliminating all the hot spots identified by the Helsinki Commission (HELCOM) for St. Petersburg. A comparison of the HELCOM strategy and the progress in developing the Russian environmental legislation is given. The experience of the enterprise in wastewater sludge handling in the light of the implementation of the HELCOM recommendations and Russian legislation is presented. Information is provided on the development of the European legislation in relation to the utilization of useful properties of municipal wastewater sludge. Development patterns are proposed to improve the Russian legislation regarding municipal wastewater sludge handling in order to avoid the emergence of new hot spots.

The experience of SUE «Vodokanal of St. Petersburg» in developing programs for improving the environmental efficiency
Summary
The experience of developing programs for improving the environmental efficiency in the context of the requirements for their development and approval by the Interdepartmental Commission under the Ministry of Industry and Trade of the Russian Federation for the facilities of SUE «Vodokanal of St. Petersburg» is presented: the Central Wastewater Treatment Plant, Northern Wastewater Treatment Plant, the Southwestern Treatment Facilities. The following issues have been accentuated: the specific features of developing programs for improving the environmental efficiency for water and wastewater utilities operating public wastewater disposal systems in settlements and urban districts that discharge effluents into the Baltic Sea catchment basin; the required dates for developing and approving the programs. Attention is drawn to the need for strict compliance with the requirements to the program components. Particularly noted are the nuances of comparing the actual quality of discharged effluents in relation to the technologically regulated substances with selected process parameters of the best available technology. Examples of the analytical evaluation of the choice of indicator values and technological solutions for the stages of the program activities are given. The focus is drawn toward the need to analyze all the best available technologies regulated by the adopted information and technical reference books. The aspects of highlighting the results of the inventory of pollution discharges in the programs are indicated.

Issues of classifying surface runoff, treatment technologies and methods (for the discussion)
Summary
An analysis of the qualitative composition of surface runoff and treatment requirements depending on the characteristics of the effluent receiving water are presented. A comprehensive approach is proposed while choosing process solutions and the basic composition of the treatment facilities to achieve the required treatment efficiency. For the implementation a classification of surface runoff and the main treatment processes with differentiation depending on the regulatory requirements to the effluent has been developed. The proposed classification provides for unifying the procedure for choosing the main process solutions.
