THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Community,

Having regard to Council Directive 96/62/EC of 27 September 1996 on ambient air quality assessment and management(1), and in particular Article 12(1) thereof,

Whereas:

(1) Directive 96/62/EC establishes the framework for assessment and management of ambient air quality and provides that detailed arrangements are to be laid down for the reporting of information on air quality.

(2) Council Directive 1999/30/EC of 22 April 1999 relating to limit values for sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter and lead in ambient air(2) lays down limit values to be met on a certain target date.

(3) Commission Decision 2001/839/EC laying down a questionnaire to be used for annual reporting on ambient air quality assessment under Directives 96/62/EC and 1999/30/EC(3) provided a model on the basis of which Member States were to provide the information on air quality required under those Directives.

(4) Directive 2000/69/EC of the European Parliament and of the Council of 16 April 2000 relating to limit values for benzene and carbon monoxide in ambient air(4) lays down limit values to be met on a certain target date. Directive 2002/3/EC of the European Parliament and of the Council of 12 February 2002 relating to ozone in ambient air(5) lays down target values, long-term objectives, information and alert thresholds which create certain obligations. Regular reporting by Member States is an integral element of those Directives, read in conjunction with Directive 96/62/EC and indispensable for checking compliance with those obligations.

(5) Moreover, a number of items set out in Article 11 of Directive 96/62/EC with regard to the pollutants covered by Directives 1999/30/EC, 2002/69/EC and 2002/3/EC must be reported on an annual basis.

(6) According to Directive 1999/30/EC, provisions on reporting under Council Directive 80/779/EEC on air quality limit values and guide values for sulphur dioxide and suspended particulates(6),Council Directive 82/884/EEC of 3 December 1982 on a limit value for lead in the air(7) and Council Directive 85/203/EEC of 7 March 1982 on air quality standards for nitrogen dioxide(8) are repealed with effect from 19 July 2001, although the limit values under these Directives remain in force until 2005 for Directives 80/779/EEC and 82/884/EEC, and 2010 for Directive 85/203/EEC and reporting on exceedences of these limit values continues according to Article 9(6) of Directive 1999/30/EC.

(7) In order to ensure that the required information is supplied in the correct format, Member States should be required to submit it on the basis of a standardised questionnaire.

(8) The questionnaire laid down by Decision 2001/839/EC should be extended to cover also the annual reporting obligations resulting from Directives 2000/69/EC and 2002/3/EC, while at the same time introducing some amendments related to Directive 1999/30/EC, which are made for clarification and in order to ensure a better assessment of the reports.

(9) Decision 2001/839/EC should be replaced in the interests of clarity.

(10) The measures provided for in this Decision are in accordance with the opinion of the Committee instituted by Article 12 (2) of Directive 96/62/EC,

HAS ADOPTED THIS DECISION:

Article 1 U.K.

Member States shall use the questionnaire set out in the Annex as a basis for forwarding the information to be provided on an annual basis in accordance with Articles 11(1) and 12(1) of Directive 96l62fEC and the following provisions:

• Articles 3(1), (3) and (4), 4(1), 5(1), (2), (4) and (5), 6, 7(1), (2) and (3), and 9(6) of Directive 1999/30/EC,

Form 1 Contact body and address U.K.

Note to Form 1: U.K.

The Member State is asked to fill in the contact body, and if possible, the contact person at national level, that the Commission may approach on details regarding this questionnaire if needed.

Form 2 Delimitation of zones and agglomerations (96/62/EC Articles 5 and ll(1b)) U.K.

Notes to Form 2: U.K.

(1) The Member State should give not only the zone name, but also a unique zone code. U.K.

(2) The Member State should indicate the pollutant(s) to which the zone applies using the codes: ‘S’ for SO₂, ‘N’ for NO₂/NO_X, ‘P’ for PM₁₀, ‘L’ for lead, ‘B’ for benzene, ‘C’ for carbon monoxide and ‘O’ for ozone, separated by a semicolon, or ‘A’ if the zone applies to all these pollutants. If zones have been separately defined for health, ecosystem and vegetation protection, the Member State should use the following codes: ‘SH’ for SO₂ health protection, ‘SE’ for SO₂ ecosystem protection, ‘NH’ for NO₂ health protection, ‘NV’ for NO_X vegetation protection. U.K.

(3) It should be indicated whether the zone is an agglomeration (code: ‘ag’) or not (code: ‘nonag’). U.K.

(4) Optionally, the Member States may add the area and population size of the zone for further processing of the data at European level. U.K.

(5) For further processing, the Member State is requested to fill in the zone borders in a standard format (polygons, using the geographical coordinates according to ISO 6709: geographical longitude and latitude). The Member State is requested to provide separately a map of the zones (as an electronic file or on paper) to facilitate the correct interpretation of the zone data. The Member State must provide at least either the zone borders in Form 2 or a map. U.K.

Form 3 Stations and measuring methods used for assessment under 1999/30/EC (Annex IX) and 2000/69/EC (Annex VII) U.K.

Notes to Form 3: U.K.

(1) In Form 3 and other forms in this questionnaire, ‘Eol station code’ refers to the code that is used for the exchange of data under the Exchange of Information Decision 97/101/EC. ‘Local station code’ is the code used within the Member State or region. U.K.

(2) The Member State is requested to identify in the third column the zone(s) applying to ozone in which the station is located. If more than one zone is concerned, the codes should be separated by a semicolon. U.K.

(3) The Member State is requested to use the columns headed by ‘SO₂’‘NO₂’‘NO_X’, ‘Lead’, ‘Benzene’ and ‘CO’ for indicating whether the measurement is used for assessment under Directive 1999/30/EC or 2000/69/EC respectively, ticking with ‘y’ if used and leaving the cell empty if not used. It should be noted that ticking NO_X implies that the station is sited at a location where the limit value for vegetation applies. If the station is in the immediate vicinity of specific sources of lead as referred to in Annex IV to Directive 1999/30/EC, the Member State is requested to tick with ‘SS’ instead of ‘y’. U.K.

(4) The Member State should use the columns headed by ‘PM₁₀’ and ‘PM_2,5’ for indicating whether the measurement is used for assessment under Directive 1999/30/EC and indicate at the same time which measurement method is used. If the measurement is used for assessment under the Directive, the Member State should fill in the measuring method code (see Note 5); if the measurement is not used for assessment under the Directive, the cell should be left empty. For PM_2,5 levels formal assessment under Article 6 of Directive 96/62/EC is not required. U.K.

(5) The measurement method code for PM₁₀ and PM_2,5 can be indicated by one of the standard codes provided by this questionnaire (see Table 1) or a code defined by the Member State that refers to a separate list of methods described by the Member State (see Form 7). The description defined by the Member State may also be a reference to a separate document added to the questionnaire. If the measurement method has been changed during the year, the Member State is requested to fill in both method codes: first the method that was used for the longest time in the year, followed by the other one, separated by a semicolon. U.K.

(6) When the measurement method for PM₁₀ or PM_2,5 is not the reference method, respectively the provisional reference method, set out in Directive 1999/30/EC, Annex IX, the Member State is requested to fill in the correction factor by which the measured concentrations have been multiplied to obtain the concentrations reported in this questionnaire or to fill in the corresponding correction equation. If a correction equation has been applied, a free format can be used in which the measured concentration should be denoted by ‘CM’ and the reported concentration by ‘CR’, preferably using the format CR = f(CM). If the results of the method have been demonstrated to be equivalent without the application of a correction, the Member State is requested to indicate this by entering the value ‘1’ for the correction factor or equation. U.K.

(7) ‘Function of station’ indicates whether the station is sited at a location where (a) the limit values for health, the SO₂ limit value for ecosystems and the NO_X limit value for vegetation apply (code ‘HEV’), (b) only the limit values for health and the SO₂ limit value for ecosystems apply (code ‘HE’), (c) only the limit value for health and the NO_X limit value for vegetation apply (code ‘HV’) or (d) only the limit values for health apply (code ‘H’). U.K.

Form 4 Stations used for assessment of ozone, including nitrogen dioxide and nitrogen oxides in relation to ozone (2002/3/EC Annex III, IV, VI) U.K.

Notes to Form 4: U.K.

(1) The Member State is requested to identify in the third column the zone in which the station is located. U.K.

(2) The Member State should use the columns headed by ‘O₃’, ‘NO₂’ and ‘NO_X’ for indicating whether the measurement is used for assessment under Directive 2002/3/EC, ticking with ‘y’ if used and leaving the cell empty if not used. The column headed by ‘NO₂’ indicates measurement as mentioned in 2002/3/EC, Article 9(1), the column headed by ‘NO_x’ indicates measurement as mentioned in 2002/3/EC, Article 9(3). U.K.

(3) ‘Type of station’ is defined according to 2002/3/EC, Annex IV. The following codes should be used: ‘U’ for urban, ‘S’ for suburban, ‘R’ for rural and ‘RB’ for rural background. U.K.

Form 5 Stations and measurement methods used for the assessment of recommended volatile organic compounds (2002/3/EC Annex VI) U.K.

Notes to Form 5: U.K.

(1) The Member State should indicate in Form 5 for each station and for each substance assessed under 2002/3/EC Article 9(3) the measurement method by one of the standard codes provided by this questionnaire (see Table 1) or a code defined by the Member State (Form 7). U.K.

(2) Whereas reporting obligations of ozone precursor substances must include “appropriate volatile organic compounds”, the list presented in Form 5 is only a recommendation according to Annex VI of Directive 2002/3/EC. U.K.

Form 6 Stations and measurement methods used for the assessment of other ozone precursor substances (2002/3/EC Annex VI) U.K.

Note to Form 6: U.K.

In the leftmost column of Form 6 the Member State should indicate ozone precursor substances assessed under 2002/3/EC Article 9(3) other than those described in Form 5. The Member State should indicate in Form 6 for each station and each substance the measurement method by one of the standard codes provided by this questionnaire (see Table 1) or a code defined by the Member State (Form 7).
