Problems of technological regulation of objects of negative impact on the environment in urban development.

. The article discusses the problems of the development of technological regulation of objects that have a negative impact on the environment in urban planning in the Russian Federation. On the one hand, the measures taken in this area are aimed at improving the regulation system in the field of environmental protection in general and reducing the techno-genic load on the Russian regions, and on the other, at increasing the efficiency and competitive ability of Russian enterprises.


Introduction
The environment in the cities of the Russian Federation and adjacent territories, where 74% of the country's population lives, is subject to significant negative impacts, which are caused by industrial, energy and transport facilities, as well as capital construction projects.Cities with high and very high levels of air pollution are home to 17.1 million people, representing 17 percent of the country's urban population [1].
Moscow is one of the most dynamically developing megacities in the world in terms of urban planning.In 2019, 10.4 million square meters real estate were built.A significant part of capital construction projects being commissioned require measures to ensure environmental safety and environmental protection at all stages of the life cycle of construction products during territorial planning, urban zoning, territory planning, architectural and construction design, construction, capital repairs, reconstruction of capital construction projects, operation of buildings and structures.On April 20, 2020, the Moscow clinical center for infectious diseases in the Voronovskoye district, a green zone of the city, was put into operation.It is one of the largest construction projects implemented in recent years in Moscow, with a capacity of more than 800-900 hospital beds.Almost a thousand medical specialists will provide assistance here.The object was built within record time of 1 month.On a plot of more than 40 hectares, there are 50 single-story buildings and 14 2-3-story buildings with a total area of 80,000 sq.m. [3,4] Fig. 1.Moscow clinical center for infectious diseases in the Voronovskoe district [3].
More than 11,000 builders and 1,500 units of construction equipment were involved in its construction.When preparing the foundation of the hospital, engineering networks and roads, more than 90 thousand cubic meters of soil were moved.During its construction, more than 200 thousand cubic meters of sand and more than 1.5 thousand tons of rebar, about 14 thousand cubic meters of concrete, 6.5 thousand tons of metal structures and about 280 thousand square meters of sandwich panels were used.Only during the construction of premises, there were installed more than 5 thousand internal and external doors and more than 3 thousand different ventilation systems [3].
There were laid approximately 100 main and internal communications systems to provide gas, electricity, and heat.Engineering networks and equipment of the infectious diseases hospital will consume about 2.5 thousand cubic meters of gas per hour.There has been constructed the water intake unit with a capacity of 1250 cubic meters per day.The water source is artesian wells.Two drinking water storage tanks with a volume of 500 cubic meters each, a water treatment plant for water purification and a pumping station that will supply treated water to the water supply network are designed [3].[3].

Fig. 2. Construction of the Moscow clinical center for infectious diseases
They paid special attention to ensuring environmental and sanitary-epidemiological safety.There has been met all regulatory requirements for the placement of a clinical center.In accordance with the provisions of SanPiN 2.1.3.2630-10"Sanitary and epidemiological requirements for organizations engaged in medical activities", medical organizations that provide medical care in stationary conditions, providing round-the-clock medical monitoring and treatment of infectious diseases are located at a distance of at least 100 meters from the territory of residential development.Hospitals of the specified profile with 1000 or more beds are located in a suburban or green zone.The established sanitary protection zone (SPZ) with a size of 250 m is 2.5 times larger than the required standards [5,6].At the entrances and exits from the territory of the infection center, there are two posts for sanitary treatment of transport.There you can simultaneously process three ambulances in each.The posts will operate around the clock and provide disinfection of 288 cars per day.
They created effective treatment facilities to prevent any waste that is contaminated or dangerous from entering the external environment.The wastewater disinfection system will allow for multi-stage cleaning.At the first stage, wastewater will be decontaminated in fiberglass tanks with a volume of 650 cubic meters using chemical reagents.At the next stage, there is planned an additional installation of a water disinfection system with ultraviolet radiation.The effluents at the outlet will meet the regulatory quality requirements for wastewater [3].
The hermetic ventilation system of premises is one of the main systems for ensuring biological safety.It prevents the release of contaminated air into the external environment and its spread between rooms.They plan to clean and decontaminate the air supplied and removed from infectious premises with devices that ensure the effectiveness of inactivation of microorganisms at the exit from the installation of at least 99 percent.For this purpose, there are provided channel installations for air inactivation [4].The scale of the tasks to be solved in the operation of such a large capital construction project, and as shown above, the volume of use of natural resources and negative impact on the environment, will require new approaches to regulating issues of reducing negative impact, protecting the environment and ensuring environmental safety based on the principles of best available technologies (BAT) [23,24].

Regulation in the field of environmental protection
In accordance with the Federal law of 10.01.2002No 7-FZ (as amended on 27.12.2019)"On environmental protection" the operation of capital construction projects must be carried out in accordance with the requirements in the field of environmental protection, including measures to preserve and restore the natural environment, rational use of natural resources, ensure environmental safety, prevent negative impacts on the environment, land reclamation, as well as taking into account compliance with environmental quality standards [2].It is determined by provisions of Federal law No 219-FZ of 21.07.2014 that all objects where legal entities and individual entrepreneurs carry out economic and (or) other activities are divided into 4 categories according to the degree of negative impact on the environment.At the same time, an object that has a negative impact on the environment is "an object of capital construction and (or) another object, as well as their combination, united by a single purpose and (or) inextricably linked physically or technologically and located within one or more land plots" [2].
According to the "Rules of creation and maintaining the state register of objects that have a negative impact on the environment" approved by Decree of the Government of the Russian Federation from 23.06.2016No. 572, the object of negative impact on the environment can include several sources of negative impact (including sources of emissions, discharges, waste disposal sites) and must meet the requirement of territorial connectivity (Fig. 4.) [7].
If a legal entity or individual entrepreneur carries out economic and (or) other activities on 2 or more production territories that are located at a significant distance from each other (including those located in different municipalities) and are not connected by pipelines, railways or otherwise (technically), it is necessary to put two or more production facilities on the state register with the corresponding submission of an application for each object (Fig. 5).
They are put on state accounting as a single object of negative impact on the environment with the execution of the corresponding application in Rosprirodnadzor.
Geographically and technically united.It should be noted that individual units of equipment that are on the balance sheet of an enterprise or organization cannot be considered as independent objects of negative impact on the environment.As well as, they do not consider land plots as objects of negative impact [7].
Objects that have a significant negative impact on the environment and are related to the areas of application of the best available technologies are classified as category 1 objects by law.For example, the implementation of economic and (or) other activities for the production of coke; for the extraction of crude oil and natural gas, including natural gas processing; for the production of petroleum products; for the extraction and processing of iron ores.In addition, the list of areas of application of the best available technologies, approved by the decree of the Government of the Russian Federation dated December 24, 2014, includes No. 2674-R includes economic and other activities that have a significant negative impact on the environment, such as mining and processing of iron ores, production of pig iron, steel and ferroalloys, production of products for further processing of ferrous metals; mining and processing of non-ferrous metals, production of non-ferrous metals; oil and natural gas production; production of coke and petroleum products, processing of natural gas, etc.As well as technological processes, equipment, technical methods and methods used in the implementation of economic and other activities, such as reducing emissions of pollutants, discharges of pollutants during storage and warehousing of goods( cargo); systems for processing (handling) waste water and waste gases in the chemical industry; industrial cooling systems; treatment of waste water and emissions of pollutants in the production of products (goods), works and services to enterprises, and others [8].
The criteria for classifying objects that have a negative impact on the environment to the appropriate category are established by the Federal law "On environmental protection" and Government Resolution No. 1029 of September 28, 2015, "On approval of criteria for classifying objects that have a negative impact on the environment as objects of categories I, II, III and IV" [2,9].They are put on state registration as several objects of negative impact on the environment with registration of the corresponding application in Rosprirodnadzor.
They are not geographically and technically combined.They are located on 2 or more production territories and are not connected by pipelines, railways, unified production control systems, or other means.

Regulation of relations arising from the use of nuclear energy.
They take into account the following provisions in accordance with the requirements of the Federal law "On environmental protection": environmental impact levels of economic and (or) other activities (industry, part of the industry, production); classification of industrial facilities and productions.This should be guided by the provisions of Federal law No. 116-FZ of 21.07.1997(as amended on 07.03.2017) "On industrial safety of hazardous production facilities", where hazardous production facilities are divided into four hazard classes depending on the level of potential danger of accidents on them: hazard class I -hazardous production facilities of extremely high hazard; hazard class II-high-hazard hazardous production facilities; hazard class III-medium-hazard hazardous production facilities; hazard class IV -hazardous production facilities of low hazard, as well as the requirements of the sanitary classification of industrial facilities, in accordance with the provisions of the SanPiN 2.2.1/2.1.1.1200-03" Sanitary protection zones and sanitary classification of enterprises, structures and other objects.New edition» [5]; features of implementation of activities in the field of nuclear energy use (table 1) [2,9].The order of the Russian Federation government of December 24, 2014 N 2674-p "List of areas of application of BAT" defines types of economic and (or) other activities that have a significant negative impact on the environment: mining and processing of iron ores, production of cast iron, steel and ferroalloys, production of products for further processing of ferrous metals; mining and processing of non-ferrous metal ores, production of non-ferrous metals; oil and natural gas production; production of coke and petroleum products, processing of natural gas; mining and processing of coal and anthracite; production of electric and thermal energy through fuel combustion; waste disposal, including thermal methods; disposal of production and consumption waste; the production of cellulose, wood pulp, paper, cardboard; production of basic organic chemicals; production of fine organic synthesis products; polymer production; production of basic inorganic chemicals-ammonia; production of inorganic acids, mineral fertilizers; production of solid and other inorganic chemicals-oxides, hydroxides, salts; production of special inorganic chemicals; production of other basic inorganic chemicals; treatment of surfaces, objects or products using organic solvents; coating metals and plastics using electrolytic or chemical processes; production of glass and ceramic products; production of cement, lime, and magnesium oxide; production of textile products (washing, bleaching, mercerization); dyeing of textile fibers, bleaching, dyeing of textile products; tanning, dyeing, tanning of hides and skins; pig and poultry breeding; slaughtering animals in meat processing plants, meat slaughterhouses; production of food, beverages, milk and dairy products; wastewater treatment using centralized water disposal systems in settlements and urban districts (table 1) [8].
In accordance with article 16 of the Federal law "On environmental protection" (as amended by Federal law No. 404-FZ of 29.12.2015 and No. 219-FZ of 21.07.2014), the fee for negative environmental impact is charged for the following types of environmental impact: emissions of pollutants into the atmosphere by stationary sources (emissions of pollutants); discharges of pollutants into water bodies (discharges of pollutants); storage and disposal of production and consumption waste (waste disposal).
The payment basis for calculating the fee for negative environmental impact based on the results of the reporting period is the volume or mass of emissions of pollutants, discharges of pollutants, or the volume or mass of waste placed in the reporting period of production and consumption.
The list of pollutants that are subject to state regulation in the field of environmental protection is approved by order of the Government of the Russian Federation No. 1316-R of 08.07.2015.
They assigned the appropriate category to an object that has a negative impact on the environment when it is registered on the state register of objects that have a negative impact on the environment.The object category can be changed when updating accounting information about an object that has a negative impact on the environment.
Federal law and a government decree classified the objects that have a moderate negative impact on the environment as objects of category II.Category III objects are objects that have a slight negative impact on the environment.And objects that have minimal negative impact on the environment, these are objects of category IV.
As examples of the government's decision to classify objects that have a negative impact on the environment in category I of objects, the following criteria can be cited: implementation of economic and (or) other activities for the production of the following non-metallic mineral products: glass and glass products, including glass fiber (with a design capacity of 20 tons per day or more); refractory ceramic products and construction ceramic materials (with a design capacity of 1 million pieces per year or more); for the production of the following food products: meat and meat products (with a design capacity of 50 tons of finished products per day or more); vegetable and animal oils and fats (with a design capacity of 75 tons of finished products per day or more); products from potatoes, fruits and vegetables (with a design capacity of 300 tons of finished products per day (quarterly average) and more); dairy products (with a design capacity of 200 tons of processed milk per day (average annual rate) or more).
Assignment to an object of the corresponding category is carried out when it is put on the state register of objects that have a negative impact on the environment and are entered into the state register at the federal or regional level.This is documented by a certificate of registration with the state, which is issued by the relevant territorial authority of Rosprirodnadzor (for federal facilities) or by the authorized body of a constituent entity of the Russian Federation (for regional facilities).
If an object does not meet the criteria for classifying objects that have a negative impact on the environment as objects of categories I, II, III and IV, approved by the decree of the Government of the Russian Federation No. 1029 of 28.09.2015,such an object is not subject to state registration [9].
For each category of objects various measures of state regulation are applied.In particular, in accordance with federal law, the procedure for determining the payment base for calculating fees for negative environmental impacts and the procedure for calculating fees for negative environmental impacts, the established amount of fees for negative impacts depends on the category of enterprise.
When carrying out urban development activities, another instrument of state regulation to prevent and reduce its negative impact on the environment is the regulation in the field of environmental protection, which is carried out in order to maintain a favorable environment and ensure environmental safety.It consists in the establishment of environmental quality standards, standards of permissible environmental impact during the implementation of economic and other activities (Fig. 3).Environmental quality standards are the standards that there are established in accordance with physical, chemical, biological and other indicators for assessing the state of the environment and upon compliance with which a favorable environment is ensured (Fig. 3.).
The standards of permissible environmental impact are the standards that are established in accordance with the indicators of the impact of economic and other activities on the environment and at which the environmental quality standards are observed.
Compliance with permissible environmental impact standards, with the exception of technological standards and technical standards, must ensure compliance with environmental quality standards (Fig. 3

.).
At the same time, in accordance with article 1 of the Federal law "On environmental protection", technical standards are standards that are established for engines of mobile sources of environmental pollution in accordance with the levels of permissible impact on the environment.In addition, by the provisions of the Federal Law "On Environmental Protection" the existing permits for emissions, discharges of pollutants, waste disposal were replaced by a comprehensive permit, declaration or reporting, depending on the category of enterprise and organization.Technological regulation based on BAT was introduced, the list of regulated substances is reduced.Depending on the category for enterprises and organizations, various requirements have been established for the obligation of enterprises to develop and approve programs of industrial environmental control and increase the environmental performance of production facilities [2].

Technological regulation of objects that have a negative impact on the environment in urban development
In accordance with the Federal Law "On Environmental Protection", technological standards are the standards for emissions, discharges of pollutants, standards for permissible physical impact.They are established using technological indicators.
Technological standards are developed and established at enterprises and organizations of the 1st category that have a significant negative impact on the environment based on the volume of emissions of pollutants, the volume of consumption of energy, raw materials and other resources per unit of production.However, the technological standards are also established for objects of centralized water disposal systems of settlements or urban districts classified as category II objects, if they are issued a comprehensive environmental permit for technologically regulated substances in accordance with the procedure established by the Federal law "On environmental protection" and the decree of the Government of the Russian Federation of October 26, 2019.No. 1379 "Rules for classifying water bodies for the purpose of establishing technological indicators of BAT in the field of wastewater treatment using centralized water disposal systems of settlements and urban districts".At the same time, the main marker pollutants are regulated for the applied technological process.Rules for the development of technological standards are established by the order of the Ministry of natural resources and ecology of Russia dated 14.02.2019No. 89 "Rules for the development of technological standards"(Fig.7) [10,11].2).For example, ITS 10-2015 "Wastewater treatment using centralized wastewater systems in settlements, urban districts", ITS 8-2015 "Wastewater treatment in the production of products (goods), work and services at large enterprises" and others [12,16].
This approach can be compared with that outlined in Directive 2010/75 / EU of the European Parliament and the Council of November 24, 2010 on Industrial Emissions (Integrated Prevention and Control).
According to the Directive, BAT reference documents, drawn up for defined activities and describing applied techniques, present emissions and consumption levels, set the "emission levels associated with the best available techniques (BAT AELs)".BAT AELs means the range of emission levels obtained under normal operating conditions using a best available technique or a combination of best available techniques, as described in BAT conclusions, expressed as an average over a given period of time, under specified reference conditions [18,20,21].
For example, Best Available Techniques (BAT) Reference Document for Waste Treatment (2018) lays down information to asses BAT applicability for mechanical treatment of waste and the emissions levels associated with BAT (BAT AELs), including in order to reduce emissions to air of dust, and of particulate-bound metals, PCDD/F and dioxin-like PCBs (Table 2) [19].

In accordance with the rules for the development of technological standards, approved by order of the Ministry of Natural Resources and Ecology of Russia dated 14.02.2019No. 89 "Rules for the development of technological standards", the procedure for developing technological standards in terms of emissions and discharges of pollutants is determined.Table 3.

[10].The calculation of technological standards begins with the definition of objects of technological regulation and marker substances and is carried out by analyzing the available technical, design and operational documentation (Fig. 5) (table 5.6) [10].
The next step in the calculation of technological standards is the analysis of technological regulation objects for existing and planned objects that have negative impact on the environment.They carry it out using technical and project documentation (table 7.) [10].

Analysis of technological regulation objects
Operating objects Designed objects • The analysis is performed using: • technical documentation; • inventory data on emissions of pollutants into the air and their sources; • inventory data on discharges of pollutants into the environment and their sources; • results of industrial environmental control for several years, but no more than 5 years.
They perform analysis using data from project documentation for construction and reconstruction of capital construction projects.• As a result of the analysis of technological rationing objects, the following are described for each technological rationing object: • data on raw materials used and materials consumed in the production process, • characteristics of manufactured products, by-products and intermediates, • characteristics of waste gases and gas-air flows, • list and parameters of stationary sources of marker substances emissions, availability of gas treatment plants and their efficiency, • characteristics of wastewater,

For operating enterprises
For planned enterprises • other operational documentation for the production of products, performance of works, and provision of services for existing facilities.

Yes
• Design documentation for the construction, reconstruction of the capital construction facility for the facilities planned for commissioning and comparison with the relevant BAT information and technical reference book (Table 6.)

Yes
The result of determining the objects of technological rationing and marker substances are: • list of identified objects of technological regulation; • lists of marker substances for which technological standards will be calculated for each object of technological regulation and the object of negative impact (table 6).The indicators of marker substances emissions for each stationary source of emissions, indicators of marker substances discharges for each wastewater release as part of the object of technological regulation are determined for existing and planned enterprises using data obtained from the analysis and study of technical, operational and project documentation, information and technical reference books of BAT (Fig. 6).
The values of the annual gross emission, the annual discharge mass (t / year) of each marker substance M for the object of technological regulation are calculated as the sum of the mass of marker substance Mk emissions of all stationary sources of emissions (k), the (1) The value of the annual output of V products is defined as an indicator of the maximum volume of products produced at the object of technological regulation during the year for several years, but no more than five years preceding the year in which calculations of technological standards are made.
The specific values for mass emissions, discharges each marker substances per unit of output Msp are calculated by dividing the annual gross emissions, the annual mass discharges of each marker substance on the amount of annual production at the object of technological regulation [10].
How to determine the values of technological indicators for emissions, discharges and technological standards for the operating object of technological regulation depends on if the technological indicators of BAT are set as a specific value of the mass of emissions, mass of discharges of marker substances per unit of production, or if the technological indicators of BAT for emissions, discharges are set as concentrations of marker substances (table 8.) [10].Technological indicators for emissions and discharges of marker substances may not exceed the technological indicators of BAT for the objects designed and planned to be put into operation.
In accordance with the Rules of development of technological regulations, approved by order of the Ministry of natural resources and ecology of Russia from 14.02.2019No. 89, technological standards for each marker substance for the object of technological regulation are defined as the sum of the technological standards of all objects of technological regulation in the object of technological regulation.

Conclusions
As noted above, the established system of technological regulation should help to reduce the negative impact on the environment, environmental risks, and the formation of an effective and environmentally oriented model for the development of urban development activities.However, this requires resolving a number of problems at this stage.For example, some already approved BAT information and technical reference books do not contain the values of technological indicators necessary for establishing technological standards and ensuring the operability of the new regulation system [25].
When updating BAT information and technical reference books the issues related to the environmental restoration of urban and industrial territories polluted by BAT application are also need to be reflected.This approach is presented in Directive 2010/75/EU of the European Parliament and of the Council of 24 November 2010 on industrial emissions (integrated pollution prevention and control).Where there is established that BAT reference documents should contain appropriate measures for remediation of contaminated sites [18,22].
Taking into account the established period of 7 years for updating the reference books, and the revision of technologies identified as the best available BAT technology is carried out at least once every ten years, the way out may be to improve existing and develop new national standards in this direction.For example, such as national standard GOST R 57446-2017 "Best available technologies.Reclamation of polluted land and sites.Restoration of biological diversity" [17].
