The presented calculations of the dissipation of pollutants are made in accordance with outdated "The method of calculating concentrations in the atmospheric air of harmful substances contained in emissions of enterprises", OND-86. It is necessary to perform calculations in accordance with the current guidelines entered by order of the MPR of Russia No. 273 of 06.06.2017 "On approval of methods for calculating emissions of harmful (polluting) substances in atmospheric air".

but)"Calculations of dispersion were carried out for the calculated platform with dimensions of 20000x15000m, the grid step - 1000m."

Comment:

In order to carry out the calculations of emissions of pollutants into the atmosphere, initial data was taken not fully, there is no necessary information on the actual and planned pollution of atmospheric air in the normalized objects (residential buildings, school, etc.). According to regulatory documents, the size of the calculated rectangle is chosen in such a way that the concentrations of 0.05 MPC, which characterizes the zone of influence of emissions of the enterprise did not go abroad of this rectangle, which corresponds to onD-86. It should be borne in mind that the setting grid step should not be greater than the regulatory size of the SPZ and ESZ or the distance to the nearest residential building (in cases where residential buildings are located inside these zones). Thus, the 1000m mesh step is not corrected in the calculation. The section must be counted taking into account the location of the residential building.

b)"The calculations of the dissipation of pollutants have shown that for all substances allocated to the atmospheric air during construction and during the operation of the objects of the prospective development of the territory of the MPC, it does not observe any of the substances. The calculation is suitable for nitrogen dioxide, nitrogen oxide, sulfur dioxide, carbon monoxide and suspended substances only with the background.

Comment:

in the presented design materials, there is no information on the distance from sources of emissions of pollutants for the period of construction and operation to normalized objects (residential buildings, schools, etc.). The calculated points in residential buildings located at a minimum distance from emission sources are not selected. The impact of the planned construction work and the period of exploitation of the railway with rail transport to residential buildings was not carried out (volume of rail transport is present 1 pp. 157, the map ZSOUTIT JV Relée).

Consequently, the entire section is designed not correctly, the information presented cannot be considered as the rationale for the placement of the rail transport branch of the rail transport, and do not allow to draw conclusions about the admissibility of construction work and the admissibility of the object's exposure for the period of operation in terms of air pollution from / p Varea.

Calculation of dispersion in the air of pollutants contained in emissions of enterprises

Under the contamination of atmospheric air, any change in its composition and properties should be understood, which has a negative impact on human and animal health, the condition of plants and ecosystems.

Pollution of the atmosphere can be:

Natural (natural) and anthropogenic (technogenic).

The contamination of the atmosphere occurs as a result of natural processes - natural sources of pollution (eruption of volcanoes, dust storms, fires, etc.) and human economic activities - anthropogenic sources - emissions of industrial enterprises and vehicles, fuel combustion for various purposes, incineration of waste and other emissions from economic activity.

These sources of pollution are characterized by inhomogeneity in composition, large concentration, uneven distribution. Emissions contain many substances that adversely affect both human health and ons, vegetation, animals and a water medium.

From the quality of the air environment, in which the person resides, its health, well-being and efficiency depends. Human health and the duration of his life is the main indicator of the environmental quality and sustainable development of the urban environment.

The atmospheric air is in contact with all elements of nature, and the deterioration of its quality leads to the death of green plantings, soil contamination, water bodies and watercourses, damage to the designs of buildings and structures, cultural monuments.

Atmospheric pollutants are foreign to the atmosphere of substance (xenobiotics), which violate the quality of the air. Under disorder, the impact leading to the accumulation of chemical compounds and substances in concentrations exceeding the established standards is implied. As a result of these exists, we should expect the occurrence of irreversible violations in the functioning of organisms, ecosystems and the biosphere as a whole.

Anthropogenic emissions into the atmosphere are divided into primary and secondary:

Primary - these are emissions entering the atmosphere directly from various sources of pollution;

Secondary are an education product due to interaction in the atmosphere of primary emissions with different substances (oxygen, ammonia, water, etc.) they may be more dangerous and toxic than primary.

Submissions polluting atmosphere can be solid, liquid and gaseous.

As the most common and dangerous, eight categories of pollutants can be distinguished:

dust and suspension, which are the smallest particles and aerosols in the air in the dispersed state;

hydrocarbons and other volatile organic compounds;

curmarket gas (CO);

nitrogen oxides (NO and NO 2);

sulfur oxides, mainly sulfur dioxide (SO 2)

lead and other heavy metals;

ozone and other photochemical oxidizers;

acids, mostly sulfur and nitric, present in the form of droplets of liquid forming acid rains and fogs.

The level of pollution in the atmosphere is determined by three factors:

The source of the intake of pollutants into the atmosphere;

The volume of space in which they are dissipated;

Mechanisms for removing air pollutants.

In order to regulate the pollution of atmospheric air in 1951 in Russia, and then in other countries of the world, extreme-permissible concentrations (MPC) of harmful substances were adopted. The determination is based on the effects of the effect of toxic substances on animals, as well as on vegetation, climate, the transparency of the atmosphere and the living conditions of the population.

The maximum permissible concentration (MPC) is the normalized sanitary and hygienic characteristics of the substance, this is the maximum concentration of impurities in the atmospheric air, attributed to a certain averaging time, which, with a periodic impact or throughout the human life, does not have any nor on the environment in The whole of harmful effects.

For each substance that polluting the atmospheric air, two standards are currently installed:

maximum permanent maximum permissible concentration for a 20-minute measurement period (averaging) - MP MR, mg / m 3;

the average daily extreme-permissible concentration, under which the concentration is averaged over a long period of time (up to a year) - PDK S.С, mg / m 3.

The maximum permissible concentrations of pollutants in atmospheric air are regulated by sanitary standards - GN 2.1.6.1338-03. "Maximum permissible concentrations (MPC) of pollutants in the atmospheric air of populated areas".

Hygienic standards as follows:

Hazard Class;

Maximum permissible maximum one-time concentration;

Maximum permissible average daily concentration.

According to the degree of impact on man, harmful substances are divided into 4 grams of danger:

extremely dangerous;

high-hazard;

moderately dangerous;

low hazard.

The hazard class is mounted depending on the average concentration of CL 50 in the air, leading to a death rate with a probability of 0.5.

Table 1

Maximum permissible concentrations of certain harmful substances in the atmospheric air

	Name of pollutant	Maximum permissible maximum one-time concentration, PDK M.R, mg / m 3	Hazard Class
	Nitrogen II oxide
	Dust finely dispersed with silicon content up to 20%
	Dust finely dispersed with silicon content up to 50%
	Sulfur dioxide (sulfur anhydride)
	Hydrogen chloride
	Hydrogen sulfide
	Carbon oxide
	Soot (carbon)
	Benz / A / Pyrene	(PDK S.С - 0.1MKG / 100M 3)
	Iron oxide	(PDK S.S - 0.04 mg / m 3)
	Iron chloride	(PDK S.S - 0.04 mg / m 3)
		(PDK S.С - 0.0017 mg / m 3)

For substances with the sum of harmful effects, the sum of their relative concentrations should not exceed the unit:

where C 1, C 2, ... with n is the actual concentration of substances in atmospheric air;

PDC 1, MPC 2, ... MPC n is the maximum permissible concentrations of the same substances.

In order for the concentration of pollutants does not exceed the MD PDC, dustless emissions are dissipated in the atmosphere through high pipes.

If this condition is not satisfied when calculating, the dustless emissions are subject to cleaning at mandatory.

Scattering pollutants in atmospheric air

Gaseous pollutants and aerosols are thrown into the atmosphere through flue pipes, aerial lights and ventilation devices. Depending on their height, the following types of emission sources are distinguished:

High (H\u003e 50 m);

Middle height (H \u003d 10 ... 50 m);

Low (n \u003d 2 ... 10 m);

Ground (N.<2 м).

The propagation of the gas mixture emitted from the source of the gas mixture in the atmosphere is determined in its lower part.

After the output of the pollutant from the emission source, they do not remain in the atmosphere unchanged. There is a change in the structure of atmospheric air in the process of dynamic phenomena, such as moving and distribution in space, turbulent diffusion, dilution, etc. Pollutants enter into chemical interaction with other components of atmospheric air, changing their quantitative and high-quality composition in time.

The emissions of pollutants contained in the accumulating gases of enterprises are carried out through house pipes, the purpose of which to remove the emission gas beyond the surface layer and dispel them. Dispersion is one of the ways to achieve established air quality standards in the surface layer of the atmosphere in the area of \u200b\u200bthe company's location.

The scattering efficiency depends on the following factors:

Height pipe N., m (300 m or more);

The height of lifting smoke (emissions) gases over the mouth of the pipes. Gas lifting height is ensured by the direction of movement at speeds w. 0 , m / s;

The process of pop-up heat gases manufactured in a colder ambient air;

Horizontal wind movement, reducing the effect of vertical speed and pop-up effect.

The gas jet, leaving the chimney, is diluted with ungubbed air, so there is a decrease in the concentration of the pollutant, which is the essence of the dispersion. The degree of emission dilution is directly dependent on the distance that this emission passed to this point. Harmful substances contained in the emission propagate in the direction of the wind within the sector, limited by a rather small angle of disclosure of the torch near the exit of the pipe at 10 0 - 20 0.

In constructing a pattern of dispersion of harmful chimneal substances, practical interest is not a vertical distribution of concentration in space (in particular, at a torch height), but a change in the concentration in the surface layer of the atmosphere, i.e. in a 2-meter layer above the ground surface, where mainly People are (Figure 1).

Figure 1. Axonometric diagram of changes in surface concentration of pollutants

Factors affecting the surface distribution of pollutants: meteorological, climatic, relief of the locality and the nature of the location of the enterprise objects on it, the height of the flue pipes and the hydrodynamic parameters of the expiration of emissions.

Meteorological factors include:

Wind speed, temperature stratification (distribution of ambient temperatures in the vertical direction near flue pipes);

Ambient temperature.

Their role is manifested in the lower layer of the atmosphere - to a height of 50 -250 m above the surface of the Earth.

Each source of emissions depending on the height of it, the volume and temperature of the gases corresponds to its so-called hazardous speed of the wind. u. m. when there is the largest surface concentration of harmful substances with m.

A strong influence on the level of surface concentration of harmful substances has a temperature stratification, which is determined by the ability of the earth's surface to absorb or emit heat. In the daytime, the earth's surface heats up and gives heat, heating the surface layer of air, but as the temperature drops upwards the temperature drops. At night, the earth's surface gives a large amount of radiant heat into the surrounding space. In this case, the earth's surface cools, cooling, the temperature of the surface layer of air is reduced, unlike the upper layers. As a result, the process of inversion (rotation) of the temperature distribution in the Earth's air shell is occurring - the temperature of the air with a height increases.

The calculation of surface concentrations of harmful substances is carried out in accordance with the requirements of regulatory documents:

OND- 86. Methods for calculating the concentrations in the atmospheric air of harmful substances contained in emissions of enterprises approved by the State Giudromete in 1986

RD. 52.04.186-89. Atmospheric Pollution Control Guide.

Calculation of scattering in the atmosphere of harmful substances from a single point source with a round mouth of emissions with a heated gas-air mixture (cold, gas-air mixture)

Determining the maximum value of the surface concentration of the pollutant with m.

To perform the calculation, a regulatory method is used, which allows you to calculate the fields of concentrations of harmful substances (emissions) created by smoke trumpets, ventilation lamps, as well as accumulations of numerous small sources.

The basis of the regulatory method is to determine the maximum value of the surface concentration C. m. .

Considering the exit of the gas-air mixture from the mouth of the emission source; H.

1 Laboratory work 1 Calculation of dispersion in an emission atmosphere harmful substances Dispersion of emissions of industrial enterprises, allocated by various sources, occurs under the action of air atmospheric streams, interacting with emissions. The turbulization of the air flow occurs as a result of its interaction with the verification of the Earth and ground structures, so under the influence of thermal interaction in the air layer, having different temperatures. The calculation of the discharging of the emission consists in determining the concentration is harmful in the surface layer of air (C, mg / m). The maximum concentration of each I-th harmful substance C, I, in the surface layer of the atmosphere should not exceed its maximum permissible concentration in the atmospheric air, i.e. C, I MPC I.

Dear subscribers, changes in environmental legislation will be expanding the imagination of environmentalists!

The Ministry of Environment of Russia still approved a new methodology for calculating the dissipation of harmful substances in the atmospheric air !!!

Interguing order "On approval of methods for calculating the dispersion of harmful (pollutant) substances in atmospheric air" dated December 26, 2016, No. 674 sent to the Ministry of Justice of Russia for the second time! For this time, should you get into the apple?!

The order was developed instead of the methodology for calculating the concentrations in the atmospheric air of harmful substances contained in the emissions of enterprises (OND-86) approved by the USSR State Gydromete 4 August 1986.

What are the calculations of dispersion of harmful substances in atmospheric air?

The approved methods for calculating the dissipation of harmful (polluting) substances in atmospheric air will allow calculations, including the average annual concentrations of pollutants that can be used to assess the long-term impact of air pollution on the environment, as well as to evaluate and minimize the risks to public health from the population Air pollution.

The document also provides recommendations for calculating the dissipation of emissions of pollutants in atmospheric air for sources of air pollution, characterized by high hazardous speeds, emission speeds into an atmosphere of SL, which exceed the speed of sound, sources of flare combustion and moving sources of air air pollution.

The project is intended for use by individuals and legal entities that perform calculations of dissipation of emissions of pollutants in atmospheric air when:

• determining the standards of emissions of harmful (polluting) substances into atmospheric air;
• conducting consolidated calculation of emission scattering from the set of IRSA for the territory of urban and other settlements and their parts, taking into account transport or other mobile funds and installations of all types that ensure transport infrastructure, as well as unauthorized sources of emissions;
• short-term and long-term forecasting and assessment of the impact of the planned economic and other activities on the environment;
• settlement assessment and forecast of short-term and long-term levels of air pollution and the corresponding background concentrations of SL;
• settlement substantiation of the size of sanitary protection zones (SZZ);
• calculation of air pollution used in numerical risk assessment for public health when exposed to chemicals polluting the environment;
• when carrying out work on territorial planning, urban-planning zoning, planning of the territory, architectural and construction design, construction of capital construction, their reconstruction, overhaul, operation of buildings, structures, and when conducting the engineering surveys necessary for these purposes, etc.

Methods for calculating the dispersion of emissions of harmful (polluting) substances in the atmospheric air are subject to use from January 1, 2018

At the same time, according to the order, the documentation developed and approved before January 1, 2018, on the basis of the calculations made in accordance with OND-86, will be valid for the period established for her.

On this we have everything, subscribe, follow the news to the site!

The note prepared my development assistant to develop the "Environmental Safety" of Ksenia Raldugin.

To be continued...

Comment from the developer of project documentation.

What happened to what we were waiting and afraid for many years. After several unsuccessful attempts and perennial "threats" to develop and implement, instead of the old good OND-86, a new sectoral regulatory document, he finally developed and even implemented. To be more accurate, now it is called non-OND, but simply methods for calculating the dispersion of emissions of harmful (polluting) substances in atmospheric air .

OND-86 for a long time remained the only document developed and approved by the main geophysical observatory. A.I. Warukov State Committee of the USSR in the prescribed manner, and it is on this technique that the calculation of pollutants from emissions from emissions in project documentation (projects of extremely permissible emissions, sanitary protection zone, a list of measures for environmental protection, etc.) and computer calculation programs work dispersion. The technique is designed to calculate surface concentrations in a two-meter layer above the surface of the Earth, as well as the vertical distribution of concentrations.

The order approval of the methods was signed at the end of 2016 by the Minister of Natural Resources and Ecology of the Russian Federation and aimed at registration with the Ministry of Justice of Russia.

Methods are subject to mandatory application from 01/01/2018, but all documents developed on the basis of the old technique will act until the end of the validity period of them.

The official reason for the emergence of a new document is to eliminate the legal gap due to the lack of approved methods approved in the prescribed manner, since OND-86 has not passed state registration and has not been published in the prescribed manner. In addition, after the introduction of onD-86, new scientific results were obtained, and there was a need to clarify and add the provisions of OND-86. Pay attention to this wording - "New scientific results". It sounds promising, but it is unclear how it is implemented in the methods.

Let us give a brief overview of the new regulatory legal act in the form in which it is accepted.

Estimated mechanism

The basic formula for calculating from OND-86 is the calculation of the air pollution by emissions of a single source - there has been no significant changes in the new document.

Maximum surface different concentration of pollutant C m (mg / m 3) during the emission of a gas-air (dusty) mixture from a single point source of emission with a round mouth is achieved at a dangerous wind velocity U M at a distance of x m from the source and is determined by the formula:

Formulas section. 5 OND-86 moved to section. 8 methods are also without significant changes.

Relief area It is still taken into account very simply - with the help of one coefficient. However, the device for calculating this coefficient is somewhat expanded. Now, if there is a height difference in more than 50 m per 1 km on the territory of the object, the coefficient is established on the basis of the analysis of the cartographic material that characterizes the terrain.

The cartographic material must be topographic maps Scale 1:25,000 or 1:10,000 with lines of equal heights of the terrain (ip-hype) and heights, as well as indicating the location of the enterprise and emission sources. At the same time, the use of topographic cards both on paper and on electronic media, incl. obtained from open sources in the Internet information and telecommunication network. This can reduce the cost of purchasing such cards.

The correction coefficients are introduced to in the presence of separately isolated shapes of the relief (hill, ridge), as well as when placing a source in the valley.

The methods introduced a new concept - virtual source of emission. A group of point sources of emissions can be combined into a virtual point source with an emission power equal to the total power of these sources.

In OND-86, the method of calculating emission scattering, taking into account the development, was submitted to Appendix 2, now this method is included in the main text of the document, but the changes did not undergo.

Section 10 of methods includes formulas for calculating long-term average, in particular average annual, concentrations of SL, which can be used to assess the long-term effects of air pollution on the environment, as well as to assess and minimize risks to public health from air pollution. This is a fundamentally new feature in the proposed calculation apparatus, it was not in the OND-86. The calculation of the field of long-range average concentrations can be carried out from a single point source and also from a group of sources.

For emission sources with permanent during the period under review, emission parameters long-range middle surface concentrations C S I is determined by the formula:

In accordance with Section. 11 "The method of accounting for the background concentrations of pollutants in calculating the contamination of atmospheric air and the definition of the background is calculated" when calculating the contamination of atmospheric air, all sources of emissions must be taken into account, incl. And those that were not included in the inventory for any other reasons. At the same time, it is obviously referred to the sources of emissions belonging to a non-specific business entity, but to other subjects.

Methods are proposed in this case to ensure the consideration of background concentrations under the proposed formulas, the consolidated calculation of the dispersion with the joint use of information assessed (already taken into account in the calculation) and on the background sources of emission. At the same time it is unclear as an enterprise should receive information about emission sources in other enterprises - Search on your own or make a request to government agencies. At the moment there is no such state function and the corresponding authorized body. The text of the document does not indicate who makes such a consolidated calculation.

Similar questions cause paragraph 11.3 of the methods:

[…]
11.3. For compromising, the data of regular observations over the state and contamination of atmospheric air is missing or by volume and / or quality do not satisfy the established requirements for observations of the background pollution of the atmosphere, and in the presence of data inventory data, the background concentrations of ZV with FR and FG It can be determined on the basis of a consolidated calculation of air pollution using the formulas of these methods, provided that in the calculation, at least 95% of the total emissions from sources, which are located on the territory under consideration or the zone of the influence of which intersects with the territory under consideration. Compliance with this condition is verified according to the state accounting data that has a negative impact on the environment [...].
[…]

It is not yet indicated who conducts the calculation of background concentrations - the economic entity itself, Roshydromet or another organization.

In section 12 "Methods for calculating emission-based emissions in atmospheric air from sources of emissions of various types" can be found methods for calculating for supergoes (temperatures of more than 3000 ° C), for which the calculation is carried out for both virtual sources; For a point source of emissions equipped with an umbrella or lid; for point sources with deviation of the mouth of the mouth; For sources with hazardous speeds (for example, for emissions from gas-pumping units of compressor stations of main gas pipelines), as well as explanations for calculating the dispersion from aircraft and ships, from explosive work in the careers, taking into account the career depth.

At the end of the section, two more points cause questions.

12.13. For SV, according to which the legislation in the field of sanitary-epidemiological well-being of the population, the maximum one-time, average daily and average annual MPCs are established, the average daily concentrations C CC Sbox are determined by the formula:

Where C MR and C SG is the maximum one-time and average annual concentration of this ZV, calculated using the formulas of these methods.
[…]

It is perplexed by the requirement of calculating the average daily maximum permissible concentrations by the formulas of this technique instead of using NDC approved on the basis of sanitary and epidemiological legislation for certain substances. The right to establish the PDC is the state, but not developers of project documentation or nature users.

Clause 12.14 provides requirements for the calculated substantiation of the calculated SPZ size, which also causes doubts, because All with regard to the SPZ and the rationale for their size is prescribed in sanitary and epidemiological legislation.

Thus, the estimated mechanism in the methods is almost no different from what was previously acted in OND-86. However, the adoption of a new document caused great resonance. At the stage of development and coordination, additional public hearings were held from 12/22/2015 until January 12, 2016, according to the results of which 79 points of comments were put forward by experts in the mathematical part (indications of many errors, errors, inaccuracies) and Parts of terminology. In addition, there were many complaints to the project of methods in terms of economic feasibility, corruption and financial burden on the business.

Remarks to project methods

Consider some of the comments given in the conclusion of the Ministry of Economic Development of Russia on the assessment of the regulatory impact on the method of methods (hereinafter - conclusion):

Note 1.

Fragment of imprisonment

In the Consolidated Report provided by the developer, the calculations of the costs of entrepreneurial activities that may arise in connection with the entry into force of the Act project, are not given.

Analysis of the possibility of further use of software products that currently ensure the calculations of surface concentrations based on OND-86 is also absent.

The project developer does not lead economic or legal reasons to change the current methods of calculating the dissipation of ZV in atmospheric air. At the same time, the reference to the developer to new scientific results (paragraphs 1.4 and 3.1 of the consolidated report), which determine the need for a draft act, in the absence of their detail cannot serve as a sufficient justification for the adoption of the Act project.

At the same time, the cancellation of OND-86 and the proposed complication of calculation methods will lead to a number of negative results for economic entities:

The need to replace the unified program for calculating the pollution of the atmosphere (hereinafter referred to as follows), which will lead to additional costs of 4 entities of entrepreneurial activities to acquire reworked forwarding programs;

The cost of calculating services will increase due to the complication of settlement methods;

Changing the methods of calculation in practice can lead to tightening emission standards;

The occurrence of the risk of late development of permits (hereinafter referred to as PDV projects) and untimely obtaining emission permits in connection with the lack of assessments of the adequacy of the transition period offered by the developer, until January 1, 2017

In addition, if a new technique simply repeats the old one with some additions, then there is a next situation. The technique is approved, and it is based on it will be developed unified Atmospheric Pollution Calculation Programs - Explosion.

To date, there are several exemplary developed by various firms and approved by the GGOs. A.I. Warikova. These programs are far from cheap, and after the adoption of a new methodology and a small modification of the Education to the developers of project documentation and all interested parties will have to buy new versions of programs, because After a year, projects with scattering calculations, made in the old versions of the programs, will not be taken to coordinate.

After this comment, the deadlines for the introduction of methods into force was the developers extended - from 01/01/2017 was postponed to 01.01.2018, but at other points the remark was not taken into account. For the remaining time, firms - program developers need to have time to develop and approve new forwards, and users buy them and master them.

Note 2.

Fragment of imprisonment

2. In paragraph 5.11, the act of the act should take the values \u200b\u200bof the maximum velocity velocity of the wind for the territory under consideration according to climate reference books or according to the explanations of the territorial bodies of Roshydromet.

In order to reduce the temporary and financial costs of business entities, it is necessary to include data at the maximum settlement speeds of the wind for the territory of the Russian Federation as an annex to the Act project.

Recommendations Apply for additional data in Roshydromet are found not only in this paragraph. And to whom, like not nature users, to know that the receipt of any information in this organization is worth a significant cost, as a result of which project prices increase. Therefore, I consider the observation objective.

Nevertheless, in the latest edition of the methods, the specified data on the values \u200b\u200bof the maximum estimated wind speed, as well as others, are not given in applications, in addition to the values \u200b\u200bof the coefficient A and the auxiliary functions used to calculate the relief coefficient. It is worth noting that the requirement "The value of the maximum estimated wind velocity for the territory under consideration is established according to the data of the wind speed distribution functions of the winds published in the climate reference books or according to the explanations of the territorial bodies of Roshydromet From the text methods removed.

Note 3.

Fragment of imprisonment

3. In accordance with paragraph 7.1 of the project of the project, it is necessary to use a cartographic material consisting of the following in accordance with the legislation of the Russian Federation on geodesy and topographic maps Scale 1:25,000 or 1:10,000 with lines of equal heights of the terrain (inlets ) and altitude marks, as well as indicating the location of the industrial site of the emission sources. [...] The service of obtaining the necessary cartographic materials is compensated, which will require certain financial costs of entities of entrepreneurial activities.

In order to exclude this type of costs to the project developers, the act is proposed to exclude the specified requirement from the project of the Act, replacing the cartographic material for publicly available areas of terrain.

This item was considered by the developer of methods, and nevertheless, in their latest revision, the requirements for the cards remained. So, this will also have to include in the cost of project development.

Note 4.

Similarly, in meaning, the previous note is contained in paragraph 4 of the conclusions, which states that it is necessary to contact Roshydromet for some data, as well as that emphasis on the basis of this methodology should be coordinated only in the GGO. A.I. Warikova. This item is practically not taken into account in the final version of the methods. Explosion is still coordinated in the GGO. A.I. Waikova, and Roshydromet gives the necessary climatic characteristics.

Note 5.

Fragment of imprisonment

5. Clause 11.1 of the Act of the Act on business entities is responsible for determining the background concentrations of the signature in the event that the regular observations of Roshydromet over the condition and pollution of atmospheric air are either absent in general, or in terms of volume and / or quality do not meet the requirements of regulatory documents approved by this department. To do this, it is proposed to use data on emission sources from which at least 95% of all total emissions on the territory under consideration or the zone of the influence of which intersects with the territory under consideration.

Obviously, obtaining the necessary data on all sources of IL emissions on a certain territory is not available for business entities. The state function on providing such data from government agencies is not carried out, the independent collection of these data by economic entities is practically impossible. Organizations - emission sources owners can simply refuse to provide information, since these information can be a state or commercial secret.

Thus, the obligation to determine the background concentrations of SN for economic entities is impossible. It is proposed to entrust the responsibility for providing data on the background concentrations of SV in atmospheric air to the Roshydromet organs for any cases - whether there are regular observations of Roshydromet over the condition and pollution of atmospheric air, or background concentrations must be determined by the calculated ways.

We mentioned this earlier in the article. Background contamination, of course, should be taken into account, and in the absence of observations, the background concentrations defined by the estimated method are given, and not to force the company to collect information on neighboring enterprises about their emissions for the PDV summary volume.

NOTE

The development of general (joint) volumes of PDV for several subjects is not prescribed by none in the Federal Law of 04.05.1999 No. 96-FZ "On the Protection of Atmospheric Air" (as amended by 07/13/2015), nor in the Decree of the Government of the Russian Federation of 02.03.2000 No. 183 "On the standards for emissions of harmful (polluting) substances into atmospheric air and harmful physical impacts on it" (as amended by 05.06.2013).

This remark was referred to the first edition of the methods, but even after editing this item, it did not change its meaning:

Extraction
From methods

[…]
11.1. If when calculating the air pollution is taken into account (i.e., are specified by their heights, emission power values \u200b\u200band other characteristics) not all sources of emission of ZV, then the calculation results must be adjusted to ensure that the contribution of backgrounds, i.e. Unaccounted, sources. If you have the required data on all emission sources, the quantitative contribution is not included directly in the calculations of the part of emission sources can be taken into account by conducting consolidated precision air pollution With the sharing of information as about those considered (already taken into account in the calculation) and on the background sources of emission. Accounting of the contribution of background sources can also be ensured by adding background concentration values \u200b\u200bto the results of calculating air pollution by emissions from recorded sources. [...]
[…]

Mention of such calculations are contained in the order of the State Committee of the Russian Federation of 02.02.1999 No. 66 "On the application of the consolidated settlement system during the rationing of emissions", where such calculations are prescribed to state bodies in the field, and in a methodological manual for calculating and regulating pollutant emissions in The atmosphere (SPB: OJSC NII atmosphere, 2012; further - a methodological manual). Based on these documents (which can be interpreted in two ways, and a methodological manual is advisable at all), it is unclear who exactly conducts consolidated scattering calculations - government agencies or nature users.

Unfortunately, in the methods, the clarity on the issue is also not introduced, although it is still a direct indication that such calculations are carried out by the economic entities themselves, from the text is removed.

"Compliance with the accounting conditions for a consolidated calculation of at least 95% of total emissions from sources that are located on the territory under consideration or the zone of the influence of which intersects with the territory under consideration is checked according to the state accounting data providing negative impact on the environment" - This suggests that the consolidated calculations will still do Rosprirodnadzor or local executive authorities as having access to the state information system for accounting objects that have a negative impact on the environment.

Note 6.

Clause 6 of the conclusion refers to the already considered calculation of the MFC of the average daily basis based on the above formula. Despite the indication of developers to the illegality of self-calculation of the MPC for substances, this requirement remains in the methods.

Note 7.

In paragraph 7 of the conclusion, attention is drawn to the fact that the order of the Government of the Russian Federation of 08.07.2015 No. 1316-p approved a list of pollutants for which state regulation measures are used in the field of environmental protection (hereinafter - the list), in connection with which it is necessary Specify, calculations are carried out only for normalized substances or for all ejected. However, in the last edition of methods, the list is mentioned, but there are no specifics:

[…]
1.1. These methods for calculating emissions of harmful (polluting) substances in the atmospheric air [...] are intended to calculate the concentrations in the atmospheric air of harmful (polluting) substances [...], including those included in the list of stumps for which state regulation measures are applied in the field of protection The environment approved by the order of the Government of the Russian Federation of 08.07.2015 No. 1316-p [...].
[…]

Judging by the wording, you will have to calculate the dispersion on all substances, as before.

Note 8.

In the project of the methods, nothing was said about the number of measurements of substances concentrations, their periodicity and location of points. In addition, it was stated that the project methods did not have control examples, on the basis of which you can check the algorithm for calculating and testing programs. After the last edition, examples of calculation in the methods did not appear (in addition to the example of calculating long-term concentrations, which was in earlier versions).

As a result, after all the battles, we have new methods for calculating emission dispersion, which are essentially an old technique in the new cover.

Output

The new regulatory legal document made only insignificant changes to the methods of calculating the dispersion, while maintaining the entire bureaucratic apparatus of coordination, issuing the necessary information, etc. Explosion will change to the minimum extent, but they will still have to pay for them to receive the coordination of projects in the future. And one of the official reasons for the introduction of a new document, namely the foggy promise of developers about accounting in it "new scientific results", in new methods and remained a promise.

The method of calculating concentrations in the atmospheric air of harmful substances contained in emissions of enterprises (OND-86) is approved by the USSR State Gydromete 04.12.1986 No. 192.

At the time of signing the room to print the order of the Ministry of Environment of Russia dated December 26, 2016 No. 674 "On approval of methods for calculating the dispersion of emissions of harmful (polluting) substances in atmospheric air" is on registration in the Ministry of Justice of Russia.
