In order to improve ambient air quality in agglomerations or zone areas where the level of ambient air pollution exceeds the air quality standards specified in Paragraph 3 of this Regulation, taking into account also the margin of tolerance, if any specified, or it is detected during the air quality assessment performed by the Centre that the average value of the level of pollution over the period of last three years exceeds the annual average value of the upper assessment threshold specified in Annex 14 to this Regulation and the level of pollution has a tendency to increase, the local government in co-operation with the Ministry of Environmental Protection and Regional Development shall draw up and implement a long-term action programme for the reduction of air pollution (hereinafter - the action programme) in accordance with the law On Pollution.

[21 February 2017]

24.1 In order to ensure a coordinated approach in respect of the measures included in various action programmes, the local government, upon developing the action programme, shall take into account the measures included in the action programmes which are developed in accordance with the laws and regulations regarding total maximum permissible emissions into the air in the State and the laws and regulations in the field of noise evaluation and management.

[21 February 2017]

24.2 Upon developing the action programme referred to in Paragraph 24 of this Regulation, the local government in co-operation with the Ministry of Environmental Protection and Regional Development shall also assess the impact on ambient air quality caused by combustion plants located in the territory of local governments. If necessary, for medium and small combustion plants in zones or zone areas where ambient air quality assessment shows potential regulatory exceedance of pollutants or exceeds the upper assessment threshold of pollution, the local government, in accordance with the law On Pollution, may impose, in the binding regulations, stricter limit values for emissions than those specified in the laws and regulations regarding combustion plants. Upon imposing stricter limit values for emissions, it is necessary to take into account the information published by the European Commission concerning emission levels which can be achieved with the best available or most recent techniques.

[21 February 2017]

25. In agglomerations or zone areas where the level of ambient air pollution is not reduced within the specified term up to the limit values referred to in Paragraph 3 of this Regulation, measures ensuring the compliance with the limit values specified in Paragraph 3 of this Regulation within as short period of time as possible shall be intended in the action programme, as well as measures which protect sensitive population groups may also be included therein.

26. In order to improve ambient air quality in agglomerations or zone areas where the level of ambient air pollution exceeds or may exceed one or several of the alert thresholds (if necessary, also in cases when one or several limit values or target values are exceeded), a local government shall draw up and implement a short-term action programme for the reduction of air pollution (hereinafter - the short-term programme). The short-term programme shall include immediate measures for the reduction of air pollution. Depending on the individual case, measures to control and suspend activities which contribute to the risk of the respective limit values or target values or alert threshold being exceeded may be included. Measures to protect sensitive population groups may also be included.

27. If the action programme or the short-term programme drawn up in accordance with this Regulation includes measures the implementation of which is not within the competence of the local government, the implementation of such measures shall be co-ordinated by the Ministry of Environmental Protection and Regional Development or by the institutions subordinated thereto.

[21 February 2017]

28. If there is a risk of exceedance of the alert threshold for ozone specified in Annex 6 to this Regulation, the local government shall only draw up the short-term programme referred to in Paragraph 26 of this Regulation when there is a potential, taking into account geographical, meteorological and economic conditions, to reduce the risk, duration, or severity of the abovementioned exceedance.

29. Local governments shall draw up the action programme or the short-term programme for agglomerations or zone areas only insofar as the exceedance of the limit value may be applied to sources of particular pollutants other than winter-sanding or -salting and pollution caused by natural sources, provided that all measures to reduce repeated concentration of dispersed particulate matter PM10 caused by winter-sanding or -salting are being performed or have already been implemented.

30. The local government shall, not later than two years after exceedance of any of the ambient air quality standards referred to in Paragraph 3 of this Regulation, taking into account the margin of tolerance, or not later than two years after the average value of the level of pollution over the period of last three years exceeds the annual average value of the upper assessment threshold of pollution specified in Annex 14 to this Regulation, in co-operation with the Ministry of Environmental Protection and Regional Development, draw up and approve the action programme in the entire territory or part thereof. The following conditions shall be taken into account in drawing up and implementing the action programme:

30.1. if air quality standards of one of pollutants referred to in Paragraph 3 of this Regulation are exceeded in agglomeration or in certain area of the zone, the action programme for reduction of air pollution with the relevant pollutant shall be drawn up;

30.2. if air quality standards of several pollutants referred to in Paragraph 3 of this Regulation are exceeded in agglomeration or in certain area of the zone, an integrated action programme shall be drawn up in which the reduction of pollutants the concentration of which exceeds air quality standards is planned, provided that the concentration of other pollutants will not increase due to implementation of the action programme;

30.3. if in agglomeration or in a certain area of the zone the concentration of pollutants does not comply with the long-term objective, financially substantiated measures shall be included in the action programme for achievement of the long-term objective.

[21 February 2017]

31. The action programme and the short-term programme shall be approved by a local government. The action programme, prior to approval thereof, shall be coordinated with the Ministry of Environmental Protection and Regional Development, receiving a positive decision therefrom, whereas the short-term programme - with the State Environmental Service, receiving a positive decision therefrom.

[21 February 2017]

32. If the agglomerations or zone areas in which the air quality standards are exceeded cover several local governments, the relevant local governments shall draw up and implement a common action programme.

33. The action programme, as well as other measures which are carried out for the improvement of ambient air quality, shall comply with the following criteria:

33.1. air, water and soil protection shall be performed in a complex way, taking into account the integrated approach;

33.2. negative impact shall not be caused on the environment outside the territory to which the action programme applies.

34. The action programme shall include the information referred to in Part I of Annex 18 to this Regulation, as well as other information arising from the legal acts of the European Union regarding the provision of information and development of the action programme in the field of ambient air protection or which is considered relevant by the developers of the action programme. Measures for limitation of emissions from fixed sources, as well as for limitation of vehicle traffic may be included in the action programme, if they cause exceedances of ambient air quality limit values. The action programme shall include the assessment of expected increase in traffic intensity which in the future could be caused by the construction of new objects and the impact thereof on ambient air quality and achievement of the objectives specified in the action programme, substantiating it with the modelling of ambient air pollution dispersion.

[21 February 2017]

35. In order not to reduce but improve ambient air quality in territories where the level is lower than the air quality standards specified in this Regulation, but it does not exceed the upper assessment threshold or is lower than the long-term objective, the relevant local governments:

35.1. may determine air quality target values for pollutants for which limit values have been determined. Air quality target values may not be lower than the upper assessment threshold of pollutants for which such is specified in Annex 14 to this Regulation and than levels of ambient air pollution observed in long-term for pollutants referred to in Paragraph 3 of this Regulation for which the upper assessment threshold is not specified;

35.2. shall determine the numerical value and determination period, as well as the term within which the air quality target values specified in accordance with Sub-paragraph 35.1 of this Regulation are to be ensured.

36. Local governments and State institutions according to the competence thereof shall implement measures in order for the air quality status not to deteriorate in zones or agglomerations where the level does not exceed the air quality standards specified in this Regulation

37. The local government which implements the action programme or the short-term programme shall, each year until 1 March, submit to the Ministry of Environmental Protection and Regional Development a report on the implementation of the programme during the previous year. The local government, within the territory of which the limit values of particulate matter PM10 are exceeded in ambient air due to repeated dispersion of particulate matter PM10 after winter-sanding or -salting, shall, in the report on the implementation of the programme, provide the information regarding measures being performed or already implemented in order to reduce the concentration of repeatedly dispersed particulate matter PM10,

1.2. on factory premises or at industrial installations to which all relevant provisions concerning health and safety at work apply;

1.3. on the carriageway of roads; and on the central reservations of roads, except where there is normally pedestrian access to the central reservation.

2. Location of ambient air monitoring stations shall comply with the following requirements:

2.1. ambient air monitoring stations directed at the protection of human health shall be sited in such a way as to:

2.1.1. provide data on the areas within zones and agglomerations where the highest concentrations occur to which the population is likely to be directly or indirectly exposed for a period which is significant in relation to the averaging period of the limit values;

2.1.2. acquire data regarding levels in other areas within the zones and agglomerations which are representative of the exposure of the general population within the relevant zone or agglomeration;

2.2. urban background locations shall be located so that their pollution level is influenced by the integrated contribution from all sources upwind of the station. The pollution level should not be dominated by a single source unless such a situation is typical for a larger urban area. Those sampling points shall, as a general rule, be representative for the territory of several square kilometres;

2.3. in assessing rural background levels, the sampling point shall not be influenced by agglomerations or industrial sites in its vicinity, i.e., sites closer than five kilometres;

2.4. in assessing contributions from industrial sources, at least one sampling point shall be installed downwind of the source in the nearest residential area. Where the background concentration is not known, an additional sampling point shall be situated within the main wind direction;

It is desirable that air quality measurements are to be applied in a territory of at least 1000 km2. Sampling points may be sited at a lesser distance and samples taken therein may represent air quality in a less extended area, taking account of geographical conditions or of the opportunities to protect particularly vulnerable areas.

3. Siting of sampling probes at the sampling point shall comply with the following conditions in so far as possible:

3.1. the airflow around the inlet sampling probe shall be unrestricted without any obstructions affecting the airflow in the vicinity of the sampler (sampling points located at the building line must be free in an arc of at least 270o or 180o). Normally these devices are positioned some metres away from buildings, trees and other obstacles and at least 0,5 m from the nearest building in the case of sampling points representing air quality at the building line;

3.2. the inlet sampling probe of airflow shall be positioned between 1,5 m (the breathing zone) and 4 m above the ground. A higher siting may be necessary if the monitoring station characterises a larger territory. If the sampling probe is positioned higher than 4 m above the ground, this information shall be included in the report which is drawn up in accordance with Paragraph 14.1 of this Regulation;

3.3. the inlet sampling probe shall not be positioned in the immediate vicinity of sources in order to avoid the direct and unmixed with ambient air intake of emitted pollutants;

3.4. the sampler's exhaust outlet shall be positioned so that recirculation of exhaust air to the sampler inlet is avoided;

3.5. sampling probes intended for measuring the pollution caused by vehicles shall be sited in the distance of at least 25 m from major junctions (such junctions which stop the traffic flow and cause different emissions (stop and start) compared to the rest of the road) and not farther than 10 m from the edge of the curbside;

3.6. in establishing ambient air monitoring station, the following factors shall be taken into account:

3.6.1. interfering sources;

3.6.2. security of sampling probe,

3.6.3. accessibility of sampling point;

3.6.4. availability of electrical power and telephone communications;

3.6.5. visibility of the sampling point in relation to its surroundings;

3.6.6. safety of the public and operators;

3.6.7. the possibility to establish sampling points for different pollutants in the vicinity;

3.6.8. territorial planning requirements.

1.3.4. annual average 30 % 50 % 50 % -
1.4. Objective estimation uncertainty 75 % 100 % 100 % 75 %

Notes.

1. * Member States may apply random measurements instead of fixed measurements for benzene, lead and particulate matter PM10 and particulate matter PM2,5 if they can demonstrate that the uncertainty, including the uncertainty due to random sampling, meets the quality objective of 25 % and the time coverage is still larger than the minimum time coverage for indicative measurements. Random sampling must be evenly distributed over the year in order to avoid skewing of results. The uncertainty due to random sampling may be determined by the procedure laid down in ISO 11222 (2002) "Air Quality - Determination of the Uncertainty of the Time Average of Air Quality Measurements". If random measurements are used to assess the requirements of the particulate matter PM10 limit value, the 90,4 percentile (to be lower than or equal to 50 µg/m3) should be evaluated instead of the number of exceedances, which is highly influenced by data coverage.

2. ** Distributed over the year to be representative of various conditions for climate and traffic.

3. *** One day's measurement a week at random (evenly distributed over the year, or eight weeks evenly distributed over the year).

4. **** One measurement a week at random (evenly distributed over the year, or eight weeks evenly distributed over the year).

5. ***** The specified percentage of uncertainty refers to specific measurements the average value whereof has been determined for a period of time that is subject to a limit value (in respect of ozone - target value), if the confidence interval is 95 %. The uncertainty of fixed measurements is applied for a territory where conformity with the respective limit values is assessed (in respect of ozone - target value).

2. There are the following data quality objectives and requirements for air quality models in assessment of pollution by arsenic, cadmium, nickel benzo(a)pyrene and polycyclic aromatic hydrocarbons (other than benzo(a)pyrene and total gaseous mercury:

No. Conditions Benzo(a) pyrene Arsenic, cadmium and nickel Polycyclic aromatic hydrocarbons (other than benzo(a)pyrene) total gaseous mercury Total deposition
2.1. Uncertainty:        
2.1.1. fixed and indicative measurements* 50 % 40 % 50 % 70 %
2.1.2. modelling 60 % 60 % 60 % 60 %
2.2. Minimum data capture 90 % 90 % 90 % 90 %
2.3. Minimum time coverage**:        
2.3.1. fixed measurements 33 % 50 %    
2.3.2. indicative measurements 14 % 14 % 14 % 33 %

Notes.

1. * In the context of this table indicative measurements are such measurements which are conducted on a less regular basis, but which conform to the remaining data quality objectives.

2. ** Distributed evenly over a year in a way the measurements would be representative in respect of various climatic conditions and anthropogenic activities.

3. The uncertainty (expressed at a 95 % confidence level) shall be evaluated:

3.1. in accordance with the principles of the CEN Guide to the Expression of Uncertainty in Measurement and which comply with the standard LVS ENV 13005:2007, Guide to the expression of uncertainty in measurement;

3.2. pursuant to the standard LVS ISO 5725-1:2006, Accuracy (trueness and precision) of measurement methods and results - Part 1: General principles and definitions;

3.3. pursuant to the standard LVS ISO 5725-2:2006, Accuracy (trueness and precision) of measurement methods and results - Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method;

3.3. pursuant to the standard LVS ISO 5725-3:2006, Accuracy (trueness and precision) of measurement methods and results - Part 3: Intermediate measures of the precision of a standard measurement method;

3.5. pursuant to the standard LVS ISO 5725-4:2006, Accuracy (trueness and precision) of measurement methods and results - Part 4: Basic methods for the determination of the trueness of a standard measurement method;

3.6. pursuant to the standard LVS ISO 5725-5:2006, Accuracy (trueness and precision) of measurement methods and results - Part 5: Alternative methods for the determination of the precision of a standard measurement method;

3.7. pursuant to the standard LVS ISO 5725-6:2006, Accuracy (trueness and precision) of measurement methods and results - Part 6: Use in practice of accuracy values;

3.8. in accordance with methodological instructions included in the European Committee for Standardisation (CEN) air quality report on uncertainty of the reference methods used for measurements of ambient air pursuant to the standard LVS CR 14377:2007, Air quality - Approach to uncertainty estimation for ambient air reference measurement methods, in which uncertainty of measurements is assessed as such which may be applied to the relevant limit value, or according to another equivalent method. In order to avoid inaccurate results, fixed and indicative measurements shall be performed at equal intervals during the entire year.

4. The uncertainty of modelling is the maximum difference between the measured and calculated concentration levels of 90 % from specific monitoring points for the period of determining the relevant limit value (in respect of ozone - target value), without taking into account the sequence of the events. The uncertainty of modelling is applied for a territory where conformity with the respective limit values is assessed (in respect of ozone - target value). Fixed measurements which must be taken for comparison with modelling results conform to the scale covered by the model. The uncertainty for objective assessment method is defined as the maximum deviation of the measured and calculated concentration, over the period considered, by the limit value (in respect of ozone - target value), without taking into account the sequence of the events.

5. Samples for benzo(a)pyrene and other polycyclic aromatic hydrocarbons shall be taken within a twenty-four-hour period. Individual samples for arsenic, cadmium, nickel, total gaseous mercury, benzo(a)pyrene and for other polycyclic aromatic hydrocarbons (of up to one month) shall be used for complex analysis, if the methods ensures sampling stability in this period. Some substances (for example, benzo(b)fluoranthene, benzo(j)fluoranthene, benzo(k)fluoranthene) can be difficult to resolve analytically. In such cases they can be reported as sum. Sampling must be spread evenly over the weekdays and the year. For the measurement of deposition rates monthly, or weekly samples throughout the year are recommended. It is allowed to use wet only instead of bulk sampling if they can demonstrate that the difference between them is within 10 % (deposition rates should generally be given as μg/m2 per day).

5.1 Particulate matter PM10 filter for taking subsamples for metal detection to carry out subsequent analysis is permitted, if there is proof that the subsample is representative in respect of aggregate and provided that detection sensitivity is not impaired in comparison with the respective data quality objectives. As an alternative for daily sampling it is possible to conduct weekly sampling for metal detection in particulate matters PM10, if characteristics of sampling are not impaired.

6. Deviation from conditions of Paragraph 3 of this Annex is allowed for fixed measurements (not lower than 14 %) and for indicative measurements (not lower than 6 %), calculated according to the standard LVS ISO 11222:2006, Air quality. Determination of the uncertainty of the time average of air quality measurements, or other equal method.

7. The requirements for minimum data capture and time coverage do not include losses of data due to regular calibration or normal maintenance of the instrumentation.

8. The number of measurement data shall be determined as percentage of time, during which the measurements performed with instrumentation are considered as valid, of the whole interval for which average concentration or other statistical indicator of pollutant is to be calculated.

9. The minimum time of measurements shall be determined as percentage of time, during which the measurements are to be performed, of the whole interval for which limit value is determined.
