(5) Air quality plans shall incorporate at least the information listed in Section A of Annex XV of the Directive and may include measures pursuant to Article 24 of the Directive.

(6) Air quality plans shall be submitted by the local authority or authorities to the Minister for evaluation and approval no less than sixteen months after the end of the year the first exceedance was observed, and the Minister shall communicate the approved plan to the Commission no later than two years after the end of the year the first exceedance was observed.

(7) Where an air quality plan is required in relation to more than one pollutant, the local authority or authorities must ensure the plans are integrated in relation to all pollutants concerned.

(8) Wherever possible, air quality plans must be consistent with other plans drawn up in accordance with obligations imposed under Directive 2001/80/EC of the European Parliament and of the Council of 23 October 2001 on the limitation of emissions of certain pollutants into the air from large combustion plants3 , Directive 2001/81/EC of the European Parliament and of the Council of 23 October 2001 on national emission ceilings for certain atmospheric pollutants4 , and Directive 2002/49/EC of the European Parliament and of the Council of 25 June 2002 relating to the assessment and management of environmental noise5 .

Short-term action plans

25. (1) Where, in a given zone or agglomeration, there is a risk that the levels of pollutants will exceed one or more of the alert thresholds specified in Annex XII of the Directive, or one or more limit values or target values specified in Annexes VII, XI and XIV of the Directive, the Agency shall notify the Minister and direct the relevant local authority or authorities to draw up short term action plans indicating the measures to be taken in the short term in order to reduce the risk or duration of such an exceedance.

(2) Where there is a risk that the alert threshold for ozone specified in Section B of Annex XII of the Directive will be exceeded, such identification, notification and direction outlined in paragraph (1) shall only apply where the Agency is of the view that there is a significant potential, taking into account national geographical, meteorological and economic conditions, to reduce the risk, duration or severity, of such an exceedance.

(3) A short-term action plan pursuant to paragraph (1) shall take account of Commission Decision 2004/279/EC6 .

(4) A short-term action plan pursuant to paragraph (1) shall include the information requirements of Section A of Annex XV of the Directive as appropriate to the exceedance type and shall be submitted to the Minister and the Agency for evaluation and approval, no less than 3 months from the date of notification by the Agency of the risk of an exceedance.

(5) The short-term action plans referred to in paragraph (1), may, depending on the individual case, provide for effective measures to control, and, where necessary, reduce or suspend activities which contribute to the risk of the respective limit values, or target values or alert thresholds being exceeded. Those action plans may include measures in relation to motor vehicle traffic, construction works, ships at berth and the use of industrial plants or products and domestic heating. Specific actions aiming at protection of sensitive population groups, including children, may also be considered in the framework of these plans.

(6) The Agency may set trigger levels of concentrations of ozone in ambient air, exceedance of which require the preparation of air pollution short-term action plans.

(7) When a local authority, or local authorities as appropriate, has drawn up a short-term action plan, they shall make available free of charge to the public and to appropriate organisations such as environmental organisations, consumer organisations, organisation representing the interests of sensitive population groups, other relevant health care bodies and the relevant industrial federations both the results of their investigations on the feasibility and the content of specific short term action plans as well as information on the implementation of such plans.

Transboundary air pollution

26. (1) The Agency shall notify the Minister and the relevant local authority, or local authorities as appropriate, in the event of an alert threshold, limit value or target value plus any relevant margin of tolerance or long-term objective being exceeded due to significant transboundary transport of air pollution or their precursors either—

(a) within the State; or

(b) in another Member State owing to transboundary transport of air pollution originating from within the State.

(2) The Agency and/or the Minister shall consult with the local authority or local authorities as appropriate as well as the relevant competent authorities in other Member States or third countries as appropriate, to cooperate and, where appropriate, draw up joint activities, such as the preparation of joint or coordinated air quality plans pursuant to Article 23 of the Directive in order to remove such exceedances through the application of appropriate but proportionate measures.

(3) The Commission shall be notified and invited to present and to assist in any co-operation pursuant to paragraph (2).

(4) Where a local authority, or local authorities as appropriate, prepare an air pollution short-term action plan under Regulation 25, with proposed measures that will or may impact upon a neighbouring zone or zones in other Member States, or where pollutant concentrations at risk of exceeding the alert threshold are due largely to precursor emissions in other Member States, the local authority, or local authorities as appropriate, shall consult with, and shall send all appropriate information pertaining to the plan to the competent authorities in those Member States with a view to co-operating, where appropriate, in the drawing up of joint short-term action plans.

(5) Where information or alert thresholds are exceeded in locations close to the borders of the State—

(a) the relevant local authority affected shall inform the Agency;

(b) the Agency shall provide prompt information to the competent authorities in other Member States as appropriate;
