COUNCIL DECISION

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

(97/101/EC)



THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community and in particular Article 130s (1), thereof,

Having regard to the proposal from the Commission ( 1 ),

Having regard to the Opinion of the Economic and Social Committee ( 2 ),

Acting in accordance with the procedure laid down in Article 189c of the Treaty ( 3 ),

(1) Whereas the fifth European Community action programme on the environment ( 4 ) provides for the collection of baseline data on the environment and an improvement in their compatibility, comparability and transparency;

(2)

Whereas the objectives and tasks of the European Environment Agency are set out in Council Regulation (EEC) No 1210/90 of 7 May 1990 on the establishment of the European Environment Agency and the European Environment Information and Observation Network ( 5 );

(3)

Whereas it is necessary to establish a procedure for the exchange of information on air quality in order to help combat pollution and nuisance, with a view to improving the quality of life and environment throughout the Community, through monitoring long-term trends and improvements resulting from national and Community legislation to combat air pollution;

(4)

Whereas duplication in transferring information should be avoided, in particular as regards information to be transmitted to the European Environment Agency and the Commission;

(5)

Whereas experience built up as the result of exchanges of information pursuant to Council Decision 75/441/EEC of 24 June 1975 establishing a common procedure for the exchange of information between the surveillance and monitoring networks based on data relating to atmospheric pollution caused by certain compounds and suspended particulates ( 6 ) and by Council Decision 82/459/EEC of 24 June 1982 establishing a reciprocal exchange of information and data from networks and individual stations measuring air pollution within the Member States ( 7 ) makes it possible to establish a more complete and representative exchange of information by increasing the number of pollutants considered and by including networks and individual stations measuring ambient air pollution;

(6)

Whereas a distinction should be made between information that must always be transmitted, in particular relating to Council Directive 96/62/EC of 27 September 1996 on ambient air quality assessment and management ( 8 ) (hereinafter referred to as ‘the Directive on air quality’), and information that must be submitted where it is available;

(7)

Whereas the information collected needs to be sufficiently representative to enable pollution levels to be mapped throughout the Community;

(8)

Whereas using common criteria for validating and processing the measurement results will increase the compatibility and comparability of the data transmitted,

HAS ADOPTED THIS DECISION:



Article 1

Objectives

1.  A reciprocal exchange of information and data from networks and individual stations measuring ambient air pollution, hereinafter referred to as ‘reciprocal exchange’, is hereby established. It shall apply to:

 networks and stations, covering detailed information describing the air-pollution monitoring networks and stations operating in the Member States,

 measurements of air quality obtained from stations: the exchange covers data calculated in accordance with points 3 and 4 of Annex I from measurements of air pollution by stations in the Member States.

2.  The Commission and the bodies referred to in Article 6 shall be responsible for the operation of the reciprocal exchange. In order to benefit from the experience acquired by the European Environment Agency and within its sphere of competence, the Commission shall call upon the Environmental Agency, inter alia as regards the operation and practical implementation of the information system.

Article 2

Pollutants

1.  The reciprocal exchange shall cover the air pollutants listed in Annex I to the Directive on air quality.

2.  Within the framework of the reciprocal exchange, the Member States shall also report on air pollutants listed in point 2 of Annex I to the extent that the relevant data are available to the bodies mentioned in Article 6 and are measured continuously by Member States.

Article 3

Stations

The reciprocal exchange, within the meaning of Article 1, covers stations:

 which are used in the framework of the implementation of directives adopted in accordance with Article 4 of the Directive on air quality,

 which, without being covered by the directives referred to in the first indent, will be selected for this purpose amongst existing stations at national level by the Member States in order to estimate local pollution levels for pollutants listed under point 2 of Annex I and regional (so called ‘background’) pollution levels for all pollutants listed in Annex I,

 as far as possible, which took part in the reciprocal exchange of information established by Decision 82/459/EEC, provided that they are not covered by the second indent.

Article 4

Required information on networks and stations

1.  The information to be communicated to the Commission shall concern the characteristics of the measurement stations, the measurement equipment and the operational procedures followed in those stations and the structure and organization of the network to which they belong. This information shall be transmitted unless it has been made available to the Commission within the existing legislation on air quality. The information required is specified on an indicative basis in Annex II. In accordance with the procedure laid down in Article 7, the Commission shall specify the minimum information which Member States shall transmit.

2.  As regards stations referred to in the first indent of Article 3 the reciprocal exchange will apply once the legislation referred to in Article 4 of the Directive on air quality is in force.

3.  Six months after the entry into force of this Decision at the latest, the Commission will make available to the Member States the existing data base containing the information already collected by its services on the subject, and software enabling it to be used and updated. The Member States shall correct, amend and/or supplement that information. The updated computer files shall be sent to the Commission during the second year following the entry into force of this Decision and by 1 October at the latest.

This information will be accessible to the public via an information system set up by the European Environment Agency; it may also be supplied by the Agency or by the Member States upon request.

4.  In accordance with the procedure laid down in Article 7, the Commission shall specify the technical procedures for the transfer of information, taking into account the provisions of Article 1 (2).

5.  Following the first sending of information by the Member States, the Commission shall include the information transmitted in its data base and prepare each year a technical report on the information collected; it shall make available to the Member States the updated ‘networks-stations’ data base at the latest by 1 July. The Member States shall correct, amend and/or supplement that information. The updated computer files shall be sent to the Commission by 1 October at the latest.

Article 5

Information to be provided on data obtained by stations

1.  The Commission shall be provided with the following results:

(a) data as defined in points 3 and 4 of Annex I for those stations referred to in the first indent of Article 3 and selected according to criteria specified in directives adopted in accordance with Article 4 of the Directive on air quality; account shall be taken of the various conditions of air quality in each Member State for the selection of those stations;

(b) at least annual data as defined in point 4 of Annex I for all the other stations referred to in the second indent of Article 3;

— for one-hour values:

Minimum data capture 75 %,

— for 24-hour values:

At least 13 one-hour values available, not more than six successive one-hour values missing.

(b)  Calculation of statistical parameters



— for the mean and the median:

minimum data capture 50 %,

— for the percentiles 98, 99,9 and the maximum:

minimum data capture 75 %.

The ratio between the number of valid data for the two seasons of the year considered cannot be greater than 2, the two seasons being winter (from January to March inclusive and from October to December inclusive) and summer (from April to September inclusive).
