S.L. 549.59 Art. 25Ozone target value.

(1) The target values for ozone shall be those prescribed in

Part II of Section D of Schedule 7.

(2) The long-term objectives for ozone shall be those prescribed in Part III of Section D of Schedule 7.

(3) In those zones and agglomerations in which the levels of ozone in ambient air are higher than the target values in sub-regulation (1), these target values shall be attained as from the dates prescribed in Part II of Section D of Schedule 7, through the implementation of the programme prepared pursuant to the National Emissions Ceilings for Certain Atmospheric Pollutants Regulations and if necessary through the implementation of an air quality plan.

(4) In those zones and agglomerations in which the levels of ozone in ambient air are higher than the long-term objectives in sub-regulation (2), but lower than or equal to the target values in sub-regulation (1), the long-term objectives shall be achieved through the implementation of cost-effective measures. These measures shall at least be consistent with all the air quality plans and the programmes in sub-regulation (3).

(5) The levels of ozone in ambient air shall be kept below the long-term objectives in sub-regulation (2) in those zones and agglomerations in which the levels of ozone in ambient air meet these long-term objectives, taking into consideration the transboundary nature of ozone pollution and meteorological conditions. The best ambient air quality compatible with a high level of environmental and human health protection shall be preserved.
