# Commission Implementing Decision of 12 December 2011 laying down rules for Directives 2004/107/EC and 2008/50/EC of the European Parliament and of the Council as regards the reciprocal exchange of information and reporting on ambient air quality (notified under document C(2011) 9068) (2011/850/EU) EU Decision 2011/850 · adopted 12 December 2011 Commission Implementing Decision of 12 December 2011 laying down rules for Directives 2004/107/EC and 2008/50/EC of the European Parliament and of the Council as regards the reciprocal exchange of information and reporting on ambient air quality (notified under document C(2011) 9068) (2011/850/EU) ## Introductory text Commission Implementing Decision of 12 December 2011 laying down rules for Directives 2004/107/EC and 2008/50/EC of the European Parliament and of the Council as regards the reciprocal exchange of information and reporting on ambient air quality (notified under document C(2011) 9068) (2011/850/EU) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive 2004/107/EC of the European Parliament and of the Council of 15 December 2004 relating to arsenic, cadmium, mercury, nickel and polycyclic aromatic hydrocarbons in ambient air, and in particular Article 5(4) thereof, Having regard to Directive 2008/50/EC of the European Parliament and of the Council of 21 May 2008 on ambient air quality and cleaner air for Europe, and in particular Article 28(2) thereof, Whereas: (1) Directive 2004/107/EC lays down target values to be met by a certain date, determines common methods and criteria for the assessment of the listed pollutants, lays down the information that needs to be transmitted to the Commission and ensures that adequate information on concentration levels of those pollutants is made available to the public. It requires that detailed arrangements for forwarding the ambient air quality information are adopted. (2) Directive 2008/50/EC establishes the framework for the assessment and management of ambient air quality. It provides that the information on ambient air quality and the timescales in which such information is to be made available by Member States are to be laid down for the reporting and the reciprocal exchange of information on air quality. It also requires that ways are identified to streamline how such information are reported and exchanged. (3) Council Decision 97/101/EC of 27 January 1997 establishing a reciprocal exchange of information and data from networks and individual stations measuring ambient air pollution within the Member States lists the information on air quality which Member States are to provide in view of the reciprocal exchange. (4) Directive 2008/50/EC provides that Decision 97/101/EC is to be repealed with effect from the end of the second calendar year following the entry into force of the implementing measures on transmission of information and reporting. Accordingly, the provisions of Decision 97/101/EC should be reflected in this Decision. (5) The scope of this Decision covers the annual reporting on ambient air quality assessment and the submission of information on plans and programmes in relation to limit values for certain pollutants in ambient air currently covered by Commission Decision 2004/224/EC of 20 February 2004 laying down arrangements for the submission of information on plans or programmes required under Council Directive 96/62/EC in relation to limit values for certain pollutants in ambient air and Commission Decision 2004/461/EC of 29 April 2004 laying down a questionnaire to be used for annual reporting on ambient air quality assessment under Council Directives 96/62/EC and 1999/30/EC and under Directives 2000/69/EC and 2002/3/EC of the European Parliament and of the Council. Accordingly, in the interest of clarity and consistency of Union legislation, those Decisions should be repealed. (6) An Internet interface called the ambient air quality portal should be created by the Commission, assisted by the European Environment Agency, where Member States should make the air quality information available and where the public has access to the environmental information made available by Member States. (7) To streamline the amount of information made available by Member States, to maximise the usefulness of such information and to reduce the administrative burden, Member States should be required to make the information available in a standardised, machine-readable form. The Commission, assisted by the European Environment Agency, should develop such a standardised machine-readable form in line with the requirements of Directive 2007/2/EC of the European Parliament and of the Council of 14 March 2007 establishing an Infrastructure for Spatial Information in the European Community (INSPIRE). It is of particular importance that the Commission carries out appropriate consultations during its preparatory work, including at expert level. (8) To reduce the administrative burden and the scope for errors, Member States should use an electronic, Internet-based tool accessible through the ambient air quality portal when making information available. That tool should be used to check the consistency of the information, the data quality and to aggregate the primary data. Where this Decision requires information to be made available in aggregate form, the tool should therefore undertake this aggregation. Member States should be able to use the tool independently from making available the ambient air quality information to the Commission to fulfil a reporting obligation or to exchange ambient air quality data. (9) The European Environment Agency should assist the Commission, as appropriate, with the management of the ambient air quality portal and the development of the tool for information consistency, data quality and aggregation of primary data. The European Environment Agency should in particular assist the Commission in the monitoring of the data repository, as well as the analysis relating to fulfilment by the Member States of their obligations under Directives 2004/107/EC and 2008/50/EC. (10) It is necessary for the Member States and the Commission to collect, exchange and assess up-to-date air quality information in order to understand better the impacts of air pollution and develop appropriate policies. In order to facilitate the handling and comparison of up-to-date air quality information, the up-to-date information should be made available to the Commission in the same standardised form as validated data within a reasonable timeframe after it has been made available to the public. (11) The measures provided for in this Decision are in accordance with the opinion of the Ambient Air Quality Committee, HAS ADOPTED THIS DECISION: ## Chapter I: GENERAL PROVISIONS ## 1 Subject matter This Decision establishes rules ... as regards: (a)appropriate authorities obligations to report on the assessment and management of ambient air quality; (b)appropriate authorities reciprocal exchange of information between each other concerning networks and stations, and the measurements of air quality obtained from those stations that are selected by appropriate authorities for the purpose of reciprocal exchange from amongst existing stations. ## 2 Definitions For the purposes of this Decision, and in addition to the definitions laid down in Article 2 of Directive 2004/107/EC, Article 3 of Directive 2007/2/EC, and Article 2 of and Annex VII to Directive 2008/50/EC, the following definitions shall apply: (1)‘station’ means a location where measurements or samples are taken at one or more sampling points at the same site within an area of approximately 100 m2; (2)‘network’ means an organisational structure performing assessment of ambient air quality by measuring at one or more stations; (3)‘measurement configuration’ means the technical facilities used for the measurement of one pollutant or one of its compounds at a certain station; (4)‘measurement data’ means information on the concentration or deposition level of a specific pollutant obtained by measurements; (5)‘modelling data’ means information on the concentration or deposition level of a specific pollutant obtained through numerical simulation of physical reality; (6)‘objective estimation data’ means information on the concentration or deposition level of a specific pollutant obtained through expert analysis and may include use of statistical tools; (7)‘primary data’ means information on the concentration or deposition level of a specific pollutant at the highest time resolution considered in this Decision; (8)‘primary up-to-date assessment data’ means primary data collected with the frequency appropriate to each pollutant assessment method and made available to the public without delay; (9)...

The time stamp refers to the end of the measurement period. ## (2) Number of digits and rounding Data should be made available with the same number of digits as they are used in the monitoring network. Rounding has to be the very last step of any calculation, i.e. immediately before comparing the result with the environmental objective and has to be done only once. By default the system will perform rounding of the data made available where appropriate following the commercial rounding rules. ## (3) Equivalence When more than one assessment method is used at a specific location, data should be supplied using the assessment method exhibiting the lowest uncertainty at that specific location. ## (4) Standardisation The provisions set out in Part IV of Annex IV to Directive 2004/107/EC and Part C of Annex VI to Directive 2008/50/EC should apply to the reciprocal exchange of information. ### Division (5): Provisions for PM2,5 ## Limit values plus margin of tolerance For PM2,5, in accordance with Part E of Annex XIV to Directive 2008/50/EC, the following sum of limit value (LV) + margin of tolerance (MOT) shall apply in the respective years mentioned below: Year LV + MOT 2008 30 2009 29 2010 29 2011 28 2012 27 2013 26 2014 26 2015 25 ## Calculation of the Average Exposure Indicator (AEI) in accordance with Part A of Annex XIV to Directive 2008/50/EC Calculation is made for each individual year, calculating PM2,5 annual means for each of the selected sampling points. The selection of the sampling points has to be evident from the appropriate information made available. Valid annual means complying with the data quality objectives are averaged over all designated AEI sites of the appropriate authorities and the appropriate authorities in Wales, Scotland and Northern Ireland and the competent authority in England must cooperate with the Secretary of State to ensure the Secretary of State is able to obtain an annual average. The procedure is repeated for each of the 3 years, and the three annual averages are then averaged to obtain the AEI. The AEI shall be made available annually as a three-year running mean. In case of a need to update any of the data that could directly or indirectly (through selection of sampling point) influence the AEI, the complete update of all affected information is necessary. ## (B) Environmental objectives and reporting metrics LV: limit value, LVMT: Limit value plus margin of tolerance, TV: target value, LTO: long-term objective, INT: Information threshold, ALT: Alert threshold, CL: Critical level, NAT: Assessment of natural contribution, WSS: Assessment of winter-sanding and -salting, ERT: Exposure reduction target, ECO: Exposure concentration obligation.
