ANNEX IISupplementary provisions
ANNEX II Directive 2008/50/EC is amended as follows: (1) Section C of Annex I is replaced by the following: ‘C. Quality assurance for ambient air quality assessment. Data validation 1. To ensure accuracy of measurements and compliance with the data quality objectives laid down in Section A, the appropriate competent authorities and bodies designated pursuant to Article 3 shall ensure the following: (i) that all measurements undertaken in relation to the assessment of ambient air quality pursuant to Articles 6 and 9 are traceable in accordance with the requirements set out in the harmonised standard for testing and calibration laboratories, (ii) that institutions operating networks and individual stations have an established quality assurance and quality control system which provides for regular maintenance to assure the continued accuracy of measuring devices. The quality system shall be reviewed as necessary and at least every five years by the relevant National Reference Laboratory (iii) that a quality assurance/quality control process is established for the process of data collection and reporting and that institutions appointed for this task actively participate, in the related Union-wide quality assurance programmes, (iv) that the National Reference Laboratories are appointed by the appropriate competent authority or body designated pursuant to Article 3 and are accredited for the reference methods referred to in Annex VI, at least for those pollutants for which concentrations are above the lower assessment threshold, according to the relevant harmonised standard for testing and calibration laboratories, the reference to which has been published in the Official Journal of the European Union pursuant to Article 2(9) of Regulation (EC) No 765/2008 setting out the requirements for accreditation and market surveillance. These laboratories shall also be responsible for the coordination in Member State's territory of the Union-wide quality assurance programmes to be organised by the Commission's Joint Research Centre and shall also be responsible for coordinating, on the national level, the appropriate use of reference methods, and the demonstration of equivalence of non-reference methods. National Reference Laboratories organising intercomparison on the national level should also be accredited according to the relevant harmonised standard for proficiency testing. (v) that the National Reference Laboratories, take part at least every three years in the Union-wide quality assurance programmes organized by the Commission's Joint Research Centre. If this participation produces unsatisfactory results then the national laboratory should demonstrate at the next participation in the intercomparison satisfactory remediation measures, and provide a report to the Joint Research Centre on these. (vi) that the national reference laboratories support the work done by the European network of National Reference Laboratories set up by the Commission. 2. All reported data under Article 27 shall be deemed to be valid except data flagged as provisional.’ (2) Annex III is amended as follows: (a) Section C is amended as follows: (i) the first and the second indents of paragraph 1 are replaced by the following: ‘— 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;’ (ii) the fifth indent of paragraph 1 is replaced by the following: ‘— 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.’ (iii) the following paragraph is added: ‘Any deviation from the criteria listed in this Section shall be fully documented through the procedures described in Section D.’ (b) Section D is replaced by the following: ‘D. Documentation 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.’ (3) Annex VI is amended as follows: (a) Section A is replaced by the following: ‘A. Reference methods for the assessment of concentrations of sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter (PM 10 and PM 2,5 ), lead, benzene, carbon monoxide and ozone 1. Reference method for the measurement of sulphur dioxide The reference method for the measurement of sulphur dioxide is that described in EN 14212:2012 “Ambient air — Standard method for the measurement of the concentration of sulphur dioxide by ultraviolet fluorescence”. 2. Reference method for the measurement of nitrogen dioxide and oxides of nitrogen The reference method for the measurement of nitrogen dioxide and oxides of nitrogen is that described in EN 14211:2012 “Ambient air — Standard method for the measurement of the concentration of nitrogen dioxide and nitrogen monoxide by chemiluminescence”. 3. Reference method for the sampling and measurement of lead — unchanged 4. Reference method for the sampling and measurement of PM 10 The reference method for the sampling and measurement of PM 10 is that described in EN12341:2014 “Ambient Air — standard gravimetric measurement method for the determination of the PM 10 or PM 2,5 mass concentration of suspended particulate matter”. 5. Reference method for the sampling and measurement of PM 2,5 The reference method for the sampling and measurement of PM 2,5 is that described in EN12341:2014 “Ambient Air — standard gravimetric measurement method for the determination of the PM 10 or PM 2,5 mass concentration of suspended particulate matter” 6. Reference method for the sampling and measurement of benzene — unchanged 7. Reference method for the measurement of carbon monoxide The reference method for the measurement of carbon monoxide is that described in EN 14626:2012 “Ambient air — Standard method for the measurement of the concentration of carbon monoxide by non-dispersive infrared spectroscopy”. 8. Reference method for measurement of ozone The reference method for the measurement of ozone is that described in EN 14625:2012 “Ambient air — Standard method for the measurement of the concentration of ozone by ultraviolet photometry”.’ (b) Section D is deleted; (c) Section E is replaced by the following: ‘When demonstrating that equipment meets the performance requirements of the reference methods listed in Section A of this Annex, the competent authorities and bodies designated pursuant to Article 3 shall accept test reports issued in other Member States provided that the test laboratories are accredited to the relevant harmonised standard for testing and calibration laboratories. The detailed test reports and all the results of the tests shall be available to other competent authorities or their designated bodies. Test reports shall demonstrate that the equipment meets all the performance requirements including where some environmental and site conditions are specific to a Member State and are outside the conditions for which the equipment has been already tested and type approved in another Member State;’ (4) Section A of Annex IX is replaced by the following: ‘A. Minimum number of sampling points for fixed measurements of concentrations of ozone Minimum number of sampling points for fixed continuous measurements to assess compliance with target values, long — term objectives and information and alert thresholds where such measurements are the sole source of information. Population (× 1 000 ) Agglomeration ( 1 ) Other zones ( 1 ) Rural background < 250 1 1 station/50 000 km 2 as an average density over all zones per country ( 2 ) < 500 1 2 < 1 000 2 2 < 1 500 3 3 < 2 000 3 4 < 2 750 4 5 < 3 750 5 6 > 3 750 One additional station per 2 million inhabitants One additional station per 2 million inhabitants ( 1 ) At least 1 station in areas where exposure of the population to the highest concentrations of ozone is likely to occur. In agglomerations, at least 50 % of the stations shall be located in suburban areas. ( 2 ) 1 station per 25 000 km 2 for complex terrain is recommended.’
