Air Quality Regulations (Northern Ireland) 2003
These Regulations prescribe the relevant authorities for particular provisions of Part III of the Environment (Northern Ireland) Order 2002. Part III of the Environment (Northern Ireland) Order 2002 requires district councils to review the quality of air within their area. The reviews have to consider the air quality for the time being and the likely future air quality during “the relevant period” (a period to be prescribed by regulations). Such reviews have to be accompanied by an assessment of whether any prescribed air quality objectives are being or are likely to be achieved within the relevant period.
