Exceedences
The Air Quality (Wales) Regulations 2000 as amended by the The Air Quality (Amendment) (Wales) Regulations 2002 lay down the targets and objects to be met by the specified date for each of the designated pollutants within the UK National Air Quality Strategy. Our air quality monitoring program has been established to assess compliance with the requirements of these regulations.
The regulations require that an assessment be made for each of the 7 key pollutants listed in the UK National Air Quality Strategy (please note that 1,3-Butadiene and Lead are not monitored in Swansea). Some pollutants eg. Sulphur Dioxide (SO2) have more than one target/objective to be met for differing integration periods. The key pollutants listed within this section have all been assessesed against the relevant integration period. Please note that several pollutants are allowed a specified number of exceedences of the regulations before it can be classed as a failure of the regulations. These exceedence pages should be read alongside the table in our FAQ section entitled "What are the key air quality pollutants" . Details of the specified number of permitted exceedences are given within this table as well as the relevant compliance dates.
