Air Quality Standards (Wales) Regulations 2007 (S.I. No. 717 (W. 63) of 2007).

These Regulations implement Community legislation on ambient air quality assessment and management, air pollution and air quality standards. They require the attainment of air quality standards in respect of the concentration of various pollutants in ambient air and designate the National Assembly of Wales as the competent authority for purposes of ambient air quality assessment and management. They define functions of the National Assembly in relation to the attainment of standards and make provision for the assessment of concentrations of pollution, the monitoring and measurement of pollution, the information of the public and the issuing of directives to local authorities.
