Aspects of designing wastewater treatment facilities in terms of the BAT process indicators: priorities and consequences
Summary
Switching to the concept of the technological regulation occurs simultaneously with implementing a number of federal environmental projects including those included in the Ecology National Project. Considering that water utilities, through the spectacle of Rosprirodnadzor are among the main polluters of water bodies, the construction of new and upgrade of the existing treatment facilities is the focus of public authorities, regulators and, naturally, the wastewater facilities operators themselves. The paper considers potential and possible inconsistencies of the current design expectations based on the technological indicators of the best available technologies and the very concept of using the best available technologies that does not imply stasis but the development and consistent tightening of those same technological indicators.

Amendments and prospects of the statutory regulation of wastewater and pollution discharges by water utilities and their customers
Summary
The background and dynamics of the environmental legislation amendments related to the water supply and wastewater disposal, and statutory regulation related to effluent and pollution discharges from public wastewater disposal systems are described. The results of applying the enactments related to wastewater disposal are stated that provided for the successive correction of the statutory regulations related to the public wastewater disposal systems beginning from 2014. The analysis of water-protective measures taken by the customers is presented in light of abandoning the state regulation of wastewater discharge into the public wastewater disposal systems. The
evaluation of the results of the amendments of «The rules of cold water supply and wastewater disposal» adopted in 2016 in relation to the customers of SUE «Vodokanal of St. Petersburg» is presented. The successive approximation of the Russian requirements to the wastewater composition and properties set with the purpose of preventing the negative impact on the public wastewater disposal systems with similar European requirements is shown. The novations coming into effect from January 1, 2019 of Federal Law No. 219-FZ «On the amendments to the Federal Law «On environmental protection» and separate enactments of the Russian Federation» and Federal Law No. 225-FZ of July 29, 2017 «On the amendments to the Federal Law «On water supply and wastewater disposal» and separate enactments of the Russian Federation» related to the system of the wastewater utilities introducing the best available techniques are stated. The prospects of the future development of the environmental regulations and legislation on water supply and wastewater disposal in relation to the regulation of the discharges by wastewater utilities and discharges to the public wastewater disposal systems by the customers are stated.

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.

Determination of technological indicators of municipal wastewater treatment quality corresponding to the use of the best available techniques
Summary
In 2015 «Wastewater treatment in public wastewater disposal systems of communities, urban districts» information and technical guidance was compiled (ITG 10-2105). The document has been developed for the first time in Russia and has no parallels in European Union. One of the main problems in compiling ITG 10-2105 was developing the methodology of determining the technological indicators of the best available techniques. The analysis of this methodology was carried out in comparison with the existing in EC perspective approaches to the determination of the technological indicators including: projects selection and split up into groups; acquisition of data on the emissions into the atmosphere; selection of pollutants; analysis of the available information on discharges; differentiated determination of the emission level in relation to the best available techniques. The technological indicators of pollutants removed in the traditional biological treatment processes (suspended solids, BOD5, COD) were determined in the process of analyzing the data obtained by questioning the branch projects. Determination of the technological indicators for nitrogen and phosphorus compounds is based greatly on the expert assessment due to the small number of projects using BAT and due to the differences in the technologies applied. Generally the method for determining the technological indicators of BAT to the full extent corresponded to the practices currently used for this purpose in EC. In future during the preparation for ITG 10-2015 revision it is recommended to carry out monitoring and technological audit of BAT reference-projects as well as of the perspective technologies.

Estimation of the achievability of the environmental and technological regulations at small wastewater treatment facilities
Summary
The transition of water and wastewater services to technological regulations imposes new environmental requirements for wastewater treatment facilities. The probability of meeting environmental and technological regulations at 117 sites was estimated. For two groups of treatment facilities (midget, small and minor), the achievability of the regulations for suspended solids, BODtotal, nitrogen (ammonium, nitrite, nitrate) and phosphate-phosphorus was determined. The smallest proportion of the facilities could provide for meeting the maximum permissible concentrations of suspended solids (12.2 and 8.8%), phosphate-phosphorus (24.5 and 8.3%) and ammonium nitrogen (12.2 and 9%) in the effluents discharged into water bodies of commercial fishing importance. Meeting the technological regulations for water bodies of category B looks more likely and is 30.6% for ammonium nitrogen, for other indicators – more than 70%.

Switch over to the technologic regulation of effluent discharges from municipal wastewater treatment facilities: ten years track record and recommendations after the adoption of the complete package of regulatory legal acts
Summary
On behalf of the participants in the process, a description of the concept of technological regulation of wastewater discharges from settlements, the development and adoption of legislative acts for the switch over to the new system is given. The paper dwells upon the adoption of the final regulatory legal act (Government Decree of September 2020 No. 1430), completing the development of a legislative framework designed to put an end on the use of fishery maximum permissible concentrations as wastewater discharge standards. Explanations are given on the relationship between the status of the provisions of the updated information and technical reference book ITS 10-2015 and the specified resolution in different applications. Recommendations are given for municipal wastewater treatment facilities and engineering companies on priority actions in the preparation and drawing up of applications for integrated environmental permits and design specifications and estimates according to the new regulations. Attention is drawn to the fact that switching over to a new regulation system requires assigning a category to a water body (performed by Rosvodresursy); otherwise the application of the process parameters established by the Government of the Russian Federation is impossible. The specific features of designing treatment facilities in the new regulation system are noted.
