SECTION 5 - AVERAGE EXPOSURE REDUCTION OBLIGATION FOR PM 2.5 AND NO 2

• A. 

  Average exposure indicator

  The Average Exposure Indicator expressed in μg/m 3 (AEI) shall be based upon

measurements in urban background locations in territorial units at NUTS 1 level throughout the territory of a Member State. It shall be assessed as a 3-calendar-year running annual mean concentration averaged over all sampling points of the relevant pollutant established pursuant to Point B of Annex III in each NUTS 1 territorial unit. The AEI for a particular year shall be the mean concentration of that same year and the

preceding 2 years.

Where Member States identify exceedances attributable to natural sources, contributions from natural sources shall be deducted before calculating the AEI.

The AEI is used for the examination of whether the average exposure reduction obligation is met.

• B. 

  Average exposure reduction obligations

  As from 2030, the AEI shall not exceed a level that is:

  – for PM 2.5 , 25% lower than the AEI was 10 years before, unless it is already no higher than the average exposure concentration objective for PM 2.5 defined in Section C.

For nitrogen dioxide, particulate matter, benzene and carbon monoxide, this shall include at least 1 sampling point focused on measuring contribution from transport emissions. However, in the cases where there is only 1 sampling point required, this shall be in the area with the highest concentrations to which the population is likely to be directly or indirectly

exposed.

For each zone, for nitrogen dioxide, particulate matter, benzene and carbon monoxide, the total number of urban background location sampling points and the total number of sampling points where the highest concentrations occur required shall not differ by more than a factor of 2. The number of PM 2.5 and nitrogen dioxide sampling points at urban

background locations shall meet the requirements set out in Point B.

For this purpose, at least 1 sampling point per 5 million inhabitants shall be established at a location where high UFP concentrations are likely to occur. Member States that have fewer than 5 million inhabitants shall establish at least 1 fixed sampling point at a location where

high UFP concentrations are likely to occur.

requirements on the minimum number of sampling points for UFP set here.

ANNEX IV

ASSESSMENT OF AMBIENT AIR QUALITY

AND LOCATION OF SAMPLING POINTS

• A. 

  General

  Ambient air quality shall be assessed in all zones as follows:

• 1. 

  Ambient air quality shall be assessed at all locations except those listed in paragraph 2.

Points B and C shall apply to the location of sampling points. The principles established by Points B and C shall also apply in so far as they are relevant in identifying the specific locations in which concentration of the relevant pollutants are established where ambient

air quality is assessed through indicative measurements or modelling.

• 2. 

  Compliance with the limit values directed at the protection of human health shall not be assessed at the following locations:

  (a) any locations situated within areas where members of the public do not have

  access and there is no fixed habitation;

  (b) in accordance with Article 4(1), on factory premises or at industrial sites to

  which all relevant provisions concerning health and safety at work apply;

  (c) on the carriageway of roads; and on the central reservations of roads except

  where there is normally pedestrian access to the central reservation.

• B. 

  Macroscale siting of sampling points

• 1. 

  Information

  The siting of sampling points shall take into account national gridded data of emissions

  reported under Directive (EU) 2016/2284 of the European Parliament and of the Council 1

  and emission data reported under the European Pollutant Release and Transfer Register.

• 2. 

  Protection of human health

  (a) Sampling points directed at the protection of human health shall be sited in such a way as to provide data on all of the following:

(i) concentration levels in the areas within zones with the highest concentrations 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 value(s),

(ii) concentration levels in other areas within the zones which are representative of

the exposure of the general population, and

(iii) for arsenic, cadmium, mercury, nickel and polycyclic aromatic hydrocarbons, the deposition rates representing the indirect exposure of the population through the

food chain;

1 Directive (EU) 2016/2284 of the European Parliament and of the Council of 14 December 2016 on the

reduction of national emissions of certain atmospheric pollutants, amending Directive 2003/35/EC i and repealing Directive 2001/81/EC i (OJ L 344, 17.12.2016, p. 1).

(b) sampling points shall in general be sited in such a way as to avoid measuring microenvironments in the immediate vicinity of the sampling point, which means that a sampling point must be sited in such a way that the air sampled is representative of air quality for a street segment no less than 100 m in length at locations measuring the contribution of road traffic and at least 250 m × 250 m at locations measuring the contribution from industrial sites or other sources such as ports or airports, where feasible;

(c) urban background locations shall be located so that their pollution level is influenced by the integrated contribution from all sources upwind of the sampling point. The pollution level shall 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 several square kilometres;

(d) where the objective is to measure the contribution of domestic heating, at least one sampling point shall be installed within the main wind direction of these sources;

(e) where the objective is to assess rural background levels, the sampling point shall not be influenced by urban areas or industrial sites in its vicinity, i.e. sites closer than 5 km;

(f) where contributions from industrial sources, ports or airports are to be assessed, at least 1 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. The sampling points shall be sited such that the application of BAT can be monitored;

(g) sampling points shall, where possible, also be representative of similar locations not in the immediate vicinity of the sampling points. In the zones where the level of air pollutants is above the assessment threshold, the area which each sampling point is representative of shall be clearly defined. The whole zone shall be covered by the different areas of representativeness defined for each sampling points;

(h) account shall be taken of the need to locate sampling points on islands where that is necessary for the protection of human health;

(i) sampling points measuring arsenic, cadmium, mercury, nickel and polycyclic aromatic hydrocarbons shall, where possible, be co-located with sampling points for PM 10 .

When defining the spatial representativeness area the following associated characteristics shall be considered:

(a) the geographical area may include non-contiguous domains but shall be limited in its extension by the borders of the air quality zone under consideration;

(b) if assessed via modelling, a fit-for-purpose modelling system shall be used and modelled concentrations shall be used at station location to prevent systematic model-measurement biases from distorting the assessment;

(c) other metrics than absolute concentrations can be considered (e.g. percentiles);

(d) the tolerance levels and possible cut-offs for the different pollutants may change depending on the station characteristics;

(e) the annual average of the observed pollutant concentration shall be used as the air quality metric for a specific year.

• 3. 

  Protection of vegetation and natural ecosystems

  Sampling points targeted at the protection of vegetation and natural ecosystems shall be sited more than 20 km away from urban areas or more than 5 km away from other builtup areas, industrial sites or motorways or major roads with traffic counts of more than 50 000 vehicles per day, which means that a sampling point must be sited in such a way that the air sampled is representative of air quality in a surrounding area of at least 1 000 km 2 . A Member State may provide for a sampling point to be sited at a lesser distance or to be representative of air quality in a less extended area, taking account of geographical conditions or of the opportunities to protect particularly vulnerable areas.

  Account shall be taken of the need to assess air quality on islands.

• 4. 

  Additional criteria for ozone sampling points

The following apply to fixed and indicative measurements:

• (1) 

  Sampling points shall, where possible, be representative of similar locations not in the immediate vicinity of the sampling points.

  The locations of sampling points for rural locations and rural background locations for ozone assessment shall, where appropriate, be coordinated with the monitoring requirements of Commission Regulation (EC) No 1737/2006 i 2 .

• C. 

  Micro-scale siting of sampling points

  In so far as is practicable, the following shall apply:

  (a) the flow around the sampling point inlet shall be unrestricted (in general free in an arc of at least 270°, or, for sampling points at the building line, of at least 180°) without any obstructions affecting the airflow in the vicinity of the inlet (at least 1,5 m away from buildings, balconies, trees and other obstacles, and at least 0,5 m from the

2 Commission Regulation (EC) No 1737/2006 i of 7 November 2006 laying down detailed rules for the

implementation of Regulation (EC) No 2152/2003 i of the European Parliament and of the Council concerning monitoring of forests and environmental interactions in the Community (OJ L 334, 30.11.2006, p. 1).

nearest building in the case of sampling points representing air quality at the building

line);

(b) in general, the sampling point inlet shall be between 0,5 m (the breathing zone) and 4 m above the ground. Higher siting (up to 8m) may be appropriate if the sampling point is representative of a large area (a background location) or in other specific circumstances and any derogations shall be fully documented;

(c) the inlet probe shall not be positioned in the immediate vicinity of sources in order to avoid the direct intake of emissions unmixed with ambient air to which members of the public are unlikely to be exposed;

(d) the sampler's exhaust outlet shall be positioned so that recirculation of exhaust air to the sampler inlet is avoided;

• (1) 

  When using indicative measurements for other purposes other than compliance assessment, such as, but not only: design or review of the monitoring network, model calibration and validation, the uncertainty may be that established for modelling applications.

  The uncertainty for measurements (expressed at a 95 % confidence level) of the assessment methods shall be calculated in line with the respective EN standard of each pollutant. For methods where no standard is available, the uncertainty of the assessment method shall be evaluated in accordance with the principles of the Joint Committee for Guidance in Metrology (JCGM) 100:2008 ‘Evaluation of measurement data - Guide to the Expression of Uncertainty in Measurement’ and the methodology in Part 5 of ISO 5725:1998. For indicative measurements, uncertainty shall be calculated according to the guidance on the demonstration of equivalence referred to in Point B of Annex VI.

  The percentages for uncertainty in the tables in this Section apply for all limit values (and the ozone target value) that are calculated by simple averaging of individual measurements such as hourly mean, daily mean or yearly mean values without considering the additional uncertainty for the calculation of the number of exceedances. The uncertainty shall be interpreted as being applicable in the region of the appropriate limit values (or ozone target value). The uncertainty calculation does not apply to AOT40 and values that include more than 1 year, more than 1 station (e.g. AEI) or more than 1 component. They are also not applicable for information thresholds, alert thresholds and critical levels for the protection of vegetation and natural ecosystems.

  The uncertainty of measurement data used for ambient air quality assessment shall not

  exceed either the absolute value or the relative value expressed in this Section.

The maximum uncertainty of modelling is set to the uncertainty for fixed measurements multiplied by the applicable maximum ratio. The modelling quality objective (i.e. a modelling quality indicator less or equal to 1) shall be verified at least at 90% of the available monitoring points, over the assessment area and period considered. At a given monitoring point, the modelling quality indicator shall be calculated as the ratio of the root mean square error(s) between modelling results and measurements over the square root of the quadratic sum(s) of the modelling and measurement uncertainties, over an entire assessment period. Note that the sum will reduce to a single value when annual means are considered. All fixed measurements meeting the data quality objectives (i.e. uncertainty of measurement and data coverage of measurement as specified in Sections A and B of this Annex, respectively) located in the modelling assessment area shall be used for the evaluation of uncertainty of modelling. Note that the maximum ratio shall be

interpreted as being applicable over the entire concentration range.

For short-term mean concentrations, the maximum uncertainty of measurement data used to assess the modelling quality objective shall be the absolute uncertainty calculated using the relative value expressed in this Section, above the limit value and shall decrease

linearly from the absolute value at the limit value, to a threshold at zero concentration 3 .

Both the short-term and long-term modelling quality objectives shall be fulfilled.

For modelling of annual mean concentrations of benzene, lead, arsenic, cadmium, nickel and benzo(a)pyrene, the maximum uncertainty of measurement data used for assessing the modelling quality objective shall not exceed the relative value expressed in this

Section.

For modelling of annual mean concentrations of PM 2.5 , PM 10 , and nitrogen dioxide the maximum uncertainty of measurement data used for assessing the modelling quality objective shall not exceed either the absolute value or the relative value expressed in this

Section.

Where an air quality model is used for assessment, references to descriptions of the model and information on the calculation of the modelling quality objective shall be

compiled.

The uncertainty of objective estimation shall not exceed the uncertainty for indicative measurements by more than the applicable maximum ratio and shall not exceed 85%. The uncertainty for objective estimation is defined as the maximum deviation of the measured and calculated concentration levels, over the period considered, by the limit value (or

ozone target value), without taking into account the timing of the events.

3 The threshold shall be set to 4, 3, 10, 3 and 5 ug/m 3 for PM 10 , PM 2.5 , O 3 , NO 2 and SO 2 , respectively and 0.5 mg/m 3 for CO. These values represent the state of knowledge and shall be regularly updated at least every 5 years, to reflect developments in the state-of-art.

• B. 

  Data coverage of measurements for ambient air quality assessment

  “Data coverage” refers to the proportion of the measurement period for which valid measurement data are available, expressed as a percentage.

Minimum data coverage

Air pollutant Fixed measurements Indicative measurements

Annual 1-hour, 8-hour Annual 1-hour, 8-hour means or 24-hour means or 24-hour means ( 1 ) means ( 1 )

SO 2 , NO 2 /NOx, CO, O 3 85 % ( 2 ) 75% ( 3 ) 13 % 50 % ( 4 )

PM 10 , PM 2.5 85 % 75% 13 % 50%

Benzene 85 % - 13 % -

Benzo(a)pyrene, polycyclic 30 % - 13 % - aromatic hydrocarbons

(PAH), total gaseous mercury

As, Cd, Ni, Pb 45 % - 13 % -

BC, Ammonia (NH 3 ), UFP, 80 % - 13 % - particle size number distribution of UFP

Total Deposition - - 30% -

• (1) 

  For O 3 and CO, the calculation of the ‘maximum daily 8-hour mean’ for any specific day requires a minimum 75% of the hourly running eight-hour averages (i.e. 18 eight-hour averages per day).

• (2) 

  For O 3 , minimum data coverage requirements are to be met both for the full calendar year, and for the periods of April to September, and October to March, respectively.

  Assessment of the AOT40 for ozone minimum data coverage requirements are to be met during the time period defined for calculating the AOT40 value.

• (3) 

  For the assessment of annual mean values, Member States may apply random measurements instead of continuous measurements if they can demonstrate to the Commission that the uncertainty, including the uncertainty due to random sampling, meets the quality objectives in the table and the time coverage is still larger than the minimum data 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’.

• (4) 

  For O 3 , minimum data coverage applies for the period of April to September (no criterium of minimum data coverage is required during the winter period).

  Fixed measurements of SO 2 , NO 2 , CO, O 3 , PM 10 , PM 2.5 and benzene are to be carried out continuously during the full calendar year.

For the other cases, measurements are to be evenly distributed over the calendar year (or over the April-September period for indicative measurements of O 3 ). In order to comply with these requirements and to ensure that any potential losses of data do not skew results, the minimum data coverage requirements shall be met for specific periods (quarter, month, weekday) of the whole year depending on the pollutant and

measurement method/frequency.

For the assessment of annual mean values via indicative measurements, Member States may apply random measurements instead of continuous measurements if they can demonstrate that the uncertainty, including the uncertainty due to random sampling, meets the required data quality objectives and minimum data coverage for indicative measurements. Such random sampling shall 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’.

The requirements for minimum data coverage do not include loss(es) of data due to the regular calibration or the normal maintenance of the instrumentation. Such maintenance

shall not take place during pollution peak periods.

24-hour sampling is required for the measurement of benzo(a)pyrene and other polycyclic aromatic hydrocarbons. Individual samples taken over a period of up to 1 month may be combined and analysed as a composite sample, provided the method ensures that the samples are stable for that period. The three congeners benzo(b)fluoranthene, benzo(j)fluoranthene, benzo(k)fluoranthene can be difficult to resolve analytically. In such cases, they can be reported as a sum together. 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.

Furthermore, those provisions on individual samples shall also apply to arsenic, cadmium, nickel and total gaseous mercury. Moreover, sub–sampling of PM 10 filters for metals for subsequent analysis is allowed, providing there is evidence that the sub-sample is representative of the whole and that the detection sensitivity is not compromised when compared with the relevant data quality objectives. As an alternative to daily sampling, weekly sampling for metals in PM 10 is allowed provided that the collection characteristics

are not compromised.

Member States may use wet sampling only, instead of bulk sampling, if they can demonstrate that the difference between them is within 10 %. Deposition rates shall

generally be given as μg/m 2 per day.

• C. 

  Methods for assessing compliance and estimating statistical parameters to account for low data coverage or significant data losses

An assessment of compliance with the relevant limit and ozone target value shall be carried out regardless of whether the data quality objectives are achieved, provided the available data allows for a conclusive assessment. In cases relating to the short-term limit and ozone target values, measurements that only cover a fraction of the calendar year, and that have not delivered sufficient valid data as required by Point B, may still constitute non-compliance. Where this is the case, and there are no clear grounds to doubt the quality of the valid data acquired, this shall be considered an exceedance of the limit

or target value and be reported as such.

• D. 

  Results of air quality assessment

  The following information shall be compiled for zones where air quality modelling or objective estimation is used:

  (a) a description of assessment activities carried out,

  (b) the specific methods used, with references to descriptions of the method,

Data quality objectives and requirements for air quality models

• I. 

  D ATA QUALITY OBJECTIVES

The following data quality objectives are provided as a guide to quality assurance.

 2015/1480 Art. 1 and Annex I.1(a)

and nickel benzo(a)pyrene, total on gaseous mercury

measurements 67

 2004/107/EC  1 2015/1480 Art. 1 and Annex I.1(b)

The uncertainty (expressed at a 95 % confidence level) of the methods used for the assessment of ambient air concentrations will be evaluated in accordance with the principles of the CEN Guide to the expression of uncertainty in measurement (ENV 13005-1999), the methodology of ISO 5725:1994, and the guidance provided in the CEN Report, ‘Air quality — Approach to uncertainty estimation for ambient air reference measurement methods’ (CR 14377:2002E). The percentages for uncertainty are given for individual measurements, which are averaged over typical sampling times, for a 95 % confidence interval. The uncertainty of the measurements should be interpreted as being applicable in the region of the appropriate target value. Fixed and indicative measurements must be evenly distributed over the year in order to avoid skewing of results.

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. Twenty-four-hour sampling is required for the measurement of benzo(a)pyrene and other polycyclic aromatic hydrocarbons. With care, individual samples taken over a period of up to one month can be combined and analysed as a composite sample, provided the method ensures that the samples are stable for that period. The three congeners benzo(b)fluoranthene, benzo(j)fluoranthene, benzo(k)fluoranthene can be difficult to resolve analytically. In such cases they can be reported as sum. 1 ---  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.

5 Distributed over the year to be representative of various conditions for climate and anthropogenic activities

6 Distributed over the year to be representative of various conditions for climate and anthropogenic activities

7 Indicative measurement being measurements which are performed at reduced regularity but fulfil the other data quality objectives

 2015/1480 Art. 1 and Annex I.1(c)

The provisions on individual samples in the previous paragraph apply also to arsenic, cadmium, nickel and total gaseous mercury. Moreover, sub–sampling of PM 10 filters for metals for subsequent analysis is allowed, providing there is evidence that the sub-sample is representative of the whole and that the detection sensitivity is not compromised when compared with the relevant data quality objectives. As an alternative to daily sampling, weekly sampling for metals in PM 10 is allowed provided that the collection characteristics are not compromised.

 2004/107/EC

Member States may 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/m 2

per day.

Member States may apply a minimum time coverage lower than indicated in the table, but not lower than 14 % for fixed measurements and 6 % for indicative measurements provided that they can demonstrate that the 95 % expanded uncertainty for the annual mean, calculated from the data quality objectives in the table according to ISO 11222:2002 — ‘Determination of the uncertainty of the time average of air quality measurements’ will be met.

II. R EQUIREMENTS FOR AIR QUALITY MODELS

Where an air quality model is used for assessment, references to descriptions of the model and information on the uncertainty shall be compiled. The uncertainty for modelling is defined as the maximum deviation of the measured and calculated concentration levels, over a full year, without taking into account the timing of the events.

III. R EQUIREMENTS FOR OBJECTIVE ESTIMATION TECHNIQUES

Where objective estimation techniques are used, the uncertainty shall not exceed 100 %.

IV. S TANDARDISATION

For substances to be analysed in the PM 10 fraction, the sampling volume refers to ambient conditions.

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 PM 10 limit value, the 90,4 percentile (to be lower than or equal to 50 μg/m 3 ) should be evaluated instead of the number of exceedances, which is highly influenced by data coverage.

The uncertainty (expressed at a 95 % confidence level) of the assessment methods will be evaluated in accordance with the principles of the CEN Guide to the Expression of Uncertainty in Measurement (ENV 13005-1999), the methodology of ISO 5725:1994 and the guidance provided in the CEN report ‘Air Quality — Approach to Uncertainty Estimation for Ambient Air Reference Measurement Methods’ (CR 14377:2002E). The percentages for uncertainty in the above table are given for individual measurements averaged over the period considered by the limit value (or target value in the case of ozone), for a 95 % confidence interval. The uncertainty for the fixed measurements shall be interpreted as being applicable in the region of the appropriate limit value (or target value in the case of ozone).

The uncertainty for modelling is defined as the maximum deviation of the measured and calculated concentration levels for 90 % of individual monitoring points, over the period considered, by the limit value (or target value in the case of ozone), without taking into account the timing of the events. The uncertainty for modelling shall be interpreted as being applicable in the region of the appropriate limit value (or target value in the case of ozone). The fixed measurements that have to be selected for comparison with modelling results shall be representative of the scale covered by the model.

The uncertainty for objective estimation is defined as the maximum deviation of the measured and calculated concentration levels, over the period considered, by the limit value (or target value in the case of ozone), without taking into account the timing of the events.

ANNEX III

Assessment of ambient air quality and location of sampling points for the measurement of sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter (PM 10

and PM 2,5 ), lead, benzene and carbon monoxide in ambient air

• A. 

  G ENERAL

Ambient air quality shall be assessed in all zones and agglomerations in accordance with the following criteria:

• 1. 

  Ambient air quality shall be assessed at all locations except those listed in paragraph 2, in accordance with the criteria established by Sections B and C for the location of sampling points for fixed measurement. The principles established by Sections B and C shall also apply in so far as they are relevant in identifying the specific locations in which concentration of the relevant pollutants are established where ambient air quality is assessed by indicative measurement or modelling.

• 2. 

  Compliance with the limit values directed at the protection of human health shall not be assessed at the following locations:

  (a) any locations situated within areas where members of the public do not have

  access and there is no fixed habitation;

(b) in accordance with Article 2(1), on factory premises or at industrial installations to which all relevant provisions concerning health and safety at work

apply;

(c) on the carriageway of roads; and on the central reservations of roads except

where there is normally pedestrian access to the central reservation.

• B. 

  M ACROSCALE SITING OF SAMPLING POINTS

• 1. 

  Protection of human health

  (a) Sampling points directed at the protection of human health shall be sited in

  such a way as to provide data on the following:

  – 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 value(s),

  – levels in other areas within the zones and agglomerations which are representative of the exposure of the general population,

(b) Sampling points shall in general be sited in such a way as to avoid measuring very small micro-environments in their immediate vicinity, which means that a sampling point must be sited in such a way that the air sampled is representative of air quality for a street segment no less than 100 m length at traffic-orientated sites

and at least 250 m × 250 m at industrial sites, where feasible;

(c) 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 several square kilometres;

(d) Where the objective is to assess 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;

(e) Where contributions from industrial sources are to be assessed, 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;

(f) Sampling points shall, where possible, also be representative of similar

locations not in their immediate vicinity;

(g) Account shall be taken of the need to locate sampling points on islands where

that is necessary for the protection of human health.

• 2. 

  Protection of vegetation and natural ecosystems

Sampling points targeted at the protection of vegetation and natural ecosystems shall be sited more than 20 km away from agglomerations or more than 5 km away from other built-up areas, industrial installations or motorways or major roads with traffic counts of more than 50000 vehicles per day, which means that a sampling point must be sited in such a way that

the air sampled is representative of air quality in a surrounding area of at least 1000 km 2 . A

Member State may provide for a sampling point to be sited at a lesser distance or to be representative of air quality in a less extended area, taking account of geographical conditions or of the opportunities to protect particularly vulnerable areas.

Account shall be taken of the need to assess air quality on islands.

• C. 

  M ICROSCALE SITING OF SAMPLING POINTS

In so far as is practicable, the following shall apply:

 2015/1480 Art. 2 and Annex II.2(a)

– the flow around the inlet sampling probe shall be unrestricted (in general free in an arc of at least 270° or 180° for sampling points at the building line) without any obstructions affecting the airflow in the vicinity of the inlet (normally some metres away from buildings, balconies, 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),

– in general, the inlet sampling point shall be between 1,5 m (the breathing zone) and 4 m above the ground. Higher siting may also be appropriate if the station is representative of a large area and any derogations should be fully documented,

 2008/50/EC

– the inlet probe shall not be positioned in the immediate vicinity of sources in order to avoid the direct intake of emissions unmixed with ambient air,

– the sampler's exhaust outlet shall be positioned so that recirculation of exhaust air to the sampler inlet is avoided,

 2015/1480 Art. 2 and Annex II.2(a)

– for all pollutants, traffic-orientated sampling probes shall be at least 25 m from the edge of major junctions and no more than 10 m from the kerbside. A ‘major junction’ to be considered here is a junction which interrupts the traffic flow and causes different emissions (stop&go) from the rest of the road.,

 2008/50/EC

The following factors may also be taken into account:

– interfering sources,

– security,

– access,

– availability of electrical power and telephone communications,

– visibility of the site in relation to its surroundings,

– safety of the public and operators,

– the desirability of co-locating sampling points for different pollutants,

– planning requirements.,

 2015/1480 Art. 2 and Annex II.2(a)

Any deviation from the criteria listed in this Section shall be fully documented through the procedures described in Section D.

 2015/1480 Art. 2 and Annex II.2(b)

• D. 

  D OCUMENTATION AND REVIEW OF SITE SELECTION

The competent authorities responsible for air quality assessment shall for all zones and agglomerations fully document the site-selection procedures and record information to support the network design and choice of location for all monitoring sites. The documentation shall include compass-point photographs of the area surrounding monitoring sites and detailed maps. Where supplementary methods are used within a zone or agglomeration, the documentation shall include details of these methods and information on how the criteria listed in Article 7(3) are met. The documentation shall be updated as necessary and reviewed at least every 5 years, to ensure that selection criteria, network design and monitoring site locations remain valid and optimal over time. The documentation shall be provided to the Commission within 3 months of being requested.

• A. 

  A VERAGE EXPOSURE INDICATOR

The Average Exposure Indicator expressed in μg/m 3 (AEI) shall be based upon measurements in urban background locations in zones and agglomerations throughout the territory of a Member State. It should be assessed as a three-calendar year running annual mean concentration averaged over all sampling points established pursuant to Section B of Annex V. The AEI for the reference year 2010 shall be the mean concentration of the years 2008, 2009 and 2010.

However, where data are not available for 2008, Member States may use the mean concentration of the years 2009 and 2010 or the mean concentration of the years 2009, 2010 and 2011. Member States making use of these possibilities shall communicate their decisions to the Commission by 11 September 2008.

The AEI for the year 2020 shall be the three-year running mean concentration averaged over all those sampling points for the years 2018, 2019 and 2020. The AEI is used for the examination whether the national exposure reduction target is met.

The AEI for the year 2015 shall be the three-year running mean concentration averaged over all those sampling points for the years 2013, 2014 and 2015. The AEI is used for the examination whether the exposure concentration obligation is met.
