Proposal for a Council Directive relating to limit values for sulphur dioxide, oxides of nitrogen, particulate matter and lead in ambient air (98/C 9/05) (Text with EEA relevance) COM(97) 500 final - 97/0266(SYN)(Submitted by the Commission on 21 November 1997)THE COUNCIL OF THE EUROPEAN UNION,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 4 (1) thereof,Having regard to the proposal from the Commission,Having regard to the opinion of the Economic and Social Committee,Acting in accordance with the procedure laid down in Article 189c of the Treaty, in cooperation with the European Parliament,Whereas, on the basis of principles enshrined in Article 130r of the Treaty, the European Community programme of policy and action in relation to the environment and sustainable development (the fifth environment action programme (2)) envisages in particular amendments to existing legislation on air pollutants; whereas the said programme recommends the establishment of long-term air quality objectives;Whereas Article 129 of the Treaty provides that health protection requirements are to form a constituent part of the Community's other policies; whereas Article 3 (o) of the Treaty provides that the activities of the Community are to include a contribution to the attainment of a high level of health protection;Whereas particles which can be inhaled and may penetrate deeply into the lungs are a matter of public health concern; whereas information should be collected on concentrations of particulate matter which may penetrate most deeply into the lung; whereas there is evidence that risks to human health associated with exposure to man-made particulate matter are higher than risks associated with exposure to naturally occurring particles in ambient air; whereas the best means of preventing diseases associated with exposure to man-made particulate matter is to reduce concentrations thereof in ambient air;Whereas vegetation should be protected against the adverse effects of nitrogen dioxide and of nitric oxide;Whereas Directive 96/62/EC provides that the numerical limit values and alert thresholds are to be based on the findings of work carried out by international scientific groups active in the field; whereas the Commission is to take account of the most recent scientific research data in the epidemiological and environmental fields concerned and of the most recent advances in metrology for re-examining the elements on which limit values and alert thresholds are based;Whereas Directive 96/62/EC requires action plans to be developed for zones within which concentrations of pollutants in ambient air exceed limit values plus applicable temporary margins of tolerance in order to ensure compliance with limit values by the date(s) specified; whereas in so far as they relate to particulate matter such action plans and other reduction strategies should aim to reduce concentrations of fine particles as part of the total reduction in concentrations of particulate matter;Whereas limit values for the protection of ecosystems or vegetation should not apply in the immediate vicinity of agglomerations and other developments;Whereas standardised accurate measurement techniques are an important element of assessment of ambient air quality;Whereas up-to-date information on concentrations of sulphur dioxide, oxides of nitrogen, particulate matter and lead in ambient air should be readily available to the public;Whereas Council Directive 80/779/EEC of 15 July 1980 on air quality limit values and guide values for sulphur dioxide and suspended particulates (3), Council Directive 82/884/EEC of 3 December 1982 on a limit value for lead in the air (4) and Council Directive 85/203/EEC of 7 March 1985 on air quality standards for nitrogen dioxide (5); all which Directives, as last amended by the Act of Accession of Austria, Finland and Sweden, should be repealed,HAS ADOPTED THIS DIRECTIVE:Article 1 ObjectivesThe aims of this Directive are:- to establish limit values and, as appropriate, alert thresholds for concentrations of sulphur dioxide, oxides of nitrogen, particulate matter and lead in ambient air designed to avoid, prevent or reduce harmful effects on human health and the environment as a whole,- to assess concentrations of sulphur dioxide, oxides of nitrogen, particulate matter and lead in ambient air on the basis of common methods and criteria,- to obtain adequate information on concentrations of sulphur dioxide, oxides of nitrogen, particulate matter and lead in ambient air and ensure that it is made available to the public,- to maintain ambient air quality where it is good and improve it in other cases with respect to sulphur dioxide, oxides of nitrogen, particulate matter and lead.Article 2 DefinitionsThe definitions in Article 2 of Directive 96/62/EC shall apply.For the purposes of this Directive:1. 'oxides of nitrogen` shall mean nitric oxide and nitrogen dioxide;2. 'PM10` shall mean particles which pass through a size selective inlet with a 50 % efficiency cut-off at 10 ìm aerodynamic diameter;3.

'upper assessment threshold` shall mean the level of pollution referred to in Article 6 (3) of Directive 96/62/EC;5. 'lower assessment threshold` shall mean the level of pollution referred to in Article 6 (4) of Directive 96/62/EC;6. 'public information indicator` shall mean a level of pollution such that, if it is exceeded over a given period, this fact shall be recorded in information disseminated pursuant to Article 8 of this Directive.Article 3 Sulphur dioxide1. Member States shall take the necessary measures to ensure that concentrations of sulphur dioxide in ambient air, as assessed in accordance with Article 7, do not exceed the limit values set out in Section I of Annex I as from the dates specified therein.The margins of tolerance set out in Section I of Annex I shall apply in accordance with Article 8 of Directive 96/62/EC.2. The alert threshold for concentrations of sulphur dioxide in ambient air is set out in Section II of Annex I. Details supplied to the public in accordance with Article 10 of Directive 96/62/EC shall include as a minimum the items listed in Section III of Annex I.3. Member States shall record data on concentrations of sulphur dioxide averaged over 10 minutes from measuring stations at which hourly concentrations are measured. Member States shall report to the Commission the 98th and 99th percentile of 10-minute concentrations measured within the calendar year at the same time as data is supplied on hourly concentrations.Article 4 Oxides of nitrogenMember States shall take the necessary measures to ensure that concentrations of nitrogen dioxide, and where applicable of nitrogen dioxide plus nitric oxide, in ambient air, as assessed in accordance with Article 7, do not exceed the limit values set out in Section I of Annex II as from the dates specified therein.The margins of tolerance set out in Section I of Annex II shall apply in accordance with Article 8 of Directive 96/62/EC.Article 5 Particulate matter1. Member States shall take the necessary measures to ensure that concentrations of PM10 in ambient air, as assessed in accordance with Article 7, do not exceed the limit values set out in Section I of Annex III as from the dates specified therein.The margins of tolerance set out in Section I of Annex III shall apply in accordance with Article 8 of Directive 96/62/EC.2. Member States shall install and operate measuring stations to supply data on concentrations of PM2,5. Where possible sampling points should be collocated with sampling points for PM10. The number and the siting of stations at which PM2,5 is measured shall be chosen by each Member State to be representative of concentrations of PM2,5 at local and regional level within that Member State.Member States shall forward to the Commission annually, no later than nine months after the end of each year, the arithmetic mean, the median, the 98th percentile and the maximum concentration calculated from measurements of PM2,5 over 24 hours within that year. The 98th percentile shall be calculated according to the procedure set out in Annex I, Section 4, to Council Decision 97/101/EC (6).3. Action plans for PM10 prepared in accordance with Article 8 of Directive 96/62/EC and general strategies for decreasing concentrations of PM10 shall aim to reduce concentrations of PM2,5 as part of the total reduction.4. Exceptionally, Member States may designate zones or agglomerations within which limit values for PM10 are exceeded owing to significant concentrations of particulate matter in ambient air due to natural sources. Member States shall end to the Commission a first list of any such zones or agglomerations together with information on concentrations and sources of PM10 and PM2,5 therein within two years of the entry into force of this Directive.Within such zones or agglomerations Member States shall apply the action levels and margins of tolerance for PM2,5 set out in Section II of Annex III in place of the limit values and margins of tolerance for PM10 in determining whether action plans should be prepared in accordance with Article 8 of Directive 96/62/EC.

Determination of exceedance of upper and lower assessment threshold Exceedance of upper and lower assessment thresholds shall be determined on the basis of concentrations during the previous five years where sufficient data are available. An assessment threshold shall be judged to have been exceeded if the total number of exceedances of the numerical concentration of the threshold during those five years exceeds three times the number of exceedances allowed per year.Where fewer than five years' data is available Member States may combine measurement campaigns of short duration during the period of the year and at locations likely to be typical of the highest pollution levels with results obtained with information from emission inventories and modelling to determine exceedances of the upper and lower assessment thresholds.ANNEX VI LOCATION OF SAMPLING POINTS FOR ASSESSMENT OF CONCENTRATIONS OF SULPHUR DIOXIDE, OXIDES OF NITROGEN, PARTICULATE MATTER AND LEAD IN AMBIENT AIR The following considerations apply to continuous and quasi-continuous measurement.I. Macroscale siting (a) Protection of human healthSampling points directed at the protection of human health should be sited:(i) to provide data on 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);(ii) to provide data on levels in other areas within the zones and agglomerations which are representative of the exposure of the general population, and with provide information for air quality management purposes.Sampling points should in general be sited to avoid measurement of very small microenvironments in their immediate vicinity.Sampling points may be representative of similar locations not in their immediate vicinity.(b) Protection of ecosystems and other vegetationSampling points targeted at the protection of ecosystems for other vegetation should be sited to be representative of air quality away from the immediate vicinity of sources such as agglomerations and other built-up areas, industrial installations and roads. As a guideline a sampling point should be sited to be representative of air quality in a surrounding area of at least 1 000 km².II. Microscale siting As a minimum the following guidelines should be met as far as practicable:- the flow around the inlet sampling probe should be unrestricted without any obstructions affecting the air flow in the vicinity of the sampler (normally some metres away from buildings, balconies, trees, and other obstacles and at least 0,5 metres from the nearest building in the case of sampling points representing air quality at the building line),- in general, the inlet sampling point should be between 1,5 metres (the breathing zone) and 4 metres above the ground. Higher positions (up to 8 metres) may be necessary in some circumstances. Higher siting may also be appropriate if the station is representative of a large area,- the inlet probe should not be positioned in the very near vicinity of sources in order to avoid direct intake of emissions unmixed with ambient air,- the sampler's exhaust outlet should be positioned so that recirculation of exhaust air to the sample inlet is avoided,- traffic-oriented samplers should be at least 25 metres from major junctions and should be no less than 4 metres from the centre of the nearest traffic lane,- traffic-oriented samplers for the measurement of NO2 should be sited less than 5 metres from the kerbside,- in built-up areas, traffic-oriented samplers for the measurement of particulate matter or lead should be sited to be representative of air quality close to the building line.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 public and operators,- the desirability of collocating sampling points for different pollutants,- planning requirements.III. Documentation and review of site selection The site selection procedures should be fully documented at the classification stage by such means as compass point photographs of the surrounding and a detailed map. Sites should be reviewed at regular intervals with repeated documentation to ensure that selection criteria remain valid over time.Member States intending to close or move measurement stations established pursuant to Directives 80/779/EEC, 82/884/EEC and 85/203/EEC for the assessment of concentrations of sulphur dioxide, nitrogen dioxide and lead shall supply information to support this decision to the Commission.ANNEX VII CRITERIA FOR DETERMINING NUMBERS OF SAMPLING POINTS FOR CONTINUOUS MEASUREMENT OF CONCENTRATIONS OF SULPHUR DIOXIDE, OXIDES OF NITROGEN, PARTICULATE MATTER AND LEAD IN AMBIENT AIR I.
