These Regulations implement the following Directives—

Directive 2008/50/EC on ambient air quality and cleaner air for Europe (this Directive replaces Council Directive 96/62/EC on ambient air quality assessment and management, Council Directive 1999/30/EC relating to limits for sulphur dioxide, nitrogen dioxide, oxides of nitrogen, particulate matter and lead in ambient air, Council Directive 2000/69/EC relating to limit values for benzene and carbon monoxide in ambient air, Council Directive 2002/3/EC relating to ozone in ambient air.)

Directive 2004/107/EC relating to arsenic, cadmium, mercury, nickel and polycyclic aromatic hydrocarbons in ambient air.

These Regulations replace the Air Quality Standards Regulations 2007 (S.I 2007/64) which are revoked.

These Regulations apply in England, except regulations 3 (a) which deals with designation of a competent authority for the purposes of cooperation with other member States, regulations 23, 24 and 25(3), which deal with reduction of exposure to PM2.5 in the UK, and regulation 32 which deals with transboundary pollution.

Part 1 of the Regulations deals with definitions, designates the Secretary of State as the competent authority for the purposes of Directives 2008/50/EC and 2004/107/EC and requires the Secretary of State to divide England into zones.

Part 2 of the Regulations deals with assessment of ambient air quality. Chapter 1 relates to assessment of sulphur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter, lead benzene and carbon monoxide. Chapter 2 relates to assessment of ozone, and Chapter 3 relates to assessment of arsenic, cadmium, nickel, mercury, benzo(a)pyrene and other polycyclic aromatic hydrocarbons.

Part 3 of the Regulations sets out the duties of the Secretary of State in relation to the limit values, target values, long-term objectives, information and alert thresholds and critical levels for the protection of vegetation which are set out in Schedules 2 to 6.

Part 4 of the Regulations deals with requirements in relation to PM2.5 in addition to the limit value and target value for this pollutant.. The additional requirements in this part relate to the calculation of an average exposure indicator (AEI) for the UK, the calculation of a national exposure reduction target based on the AEI, attainment of the national exposure reduction target in the UK and compliance with a limit on the AEI for 2015.

Part 5 of the Regulations imposes requirements on the Secretary of State to draw up air quality plans in relation to limit values and target values and short-term action plans in relation to alert thresholds. Short-term action plans may also be used in relation to limit values and target values.

Part 6 of the Regulations relates to public information.

Part 7 of the Regulations gives the Secretary of State power to direct local authorities and the Mayor of London. This part also contains provisions relating to transboundary air pollution.

Schedule 1 of the Regulations sets out the requirements for the siting of sampling points for the assessment of sulphur dioxide, nitrogen dioxide, oxides of nitrogen, particulate matter, lead, benzene and carbon dioxide.

Schedules 2 to 6 set out limit values, target values, long term objectives for ozone, information and alert thresholds and critical levels for the protection of vegetation.

Schedule 7 sets out national exposure reduction targets for PM2.5

Schedule 8 sets out the information to be included in air quality plans.

Schedule 9 sets out the public information to be provided in relation to concentrations of pollutants.
