Regulation 7(1)
General
1. Ambient air quality must be assessed at sampling points located in accordance with this Schedule, except at locations set out in paragraph 2.U.K.
2. Compliance with limit values directed at the protection of human health does not need to be assessed at the following locations—U.K.
(a)any location situated within areas where members of the public do not have access and there is no fixed habitation;
(b)on factory premises or at industrial locations to which all relevant provisions concerning health and safety at work apply;
(c)on the carriageway of roads and on the central reservations of roads except where there is normally pedestrian access to the central reservation.
3. Insofar as they are relevant, the principles set out in this Schedule also apply to indicative measurement and modelling.U.K.
Sampling points for the protection of human health
1. Sampling points directed at the protection of human health must be sited to provide data on—U.K.
(a)the areas within zones where the highest concentrations occur to which the population is likely to be directly or indirectly exposed for a period which is significant in relation to the averaging period of any limit value; and
(b)levels in other areas within the zones which are representative of the exposure of the general population.
2. Sampling points must in general be sited to avoid measuring very small micro-environments in their immediate vicinity. Where feasible, the Secretary of State must locate sampling points so as to be representative of air quality in a street segment of no less than 100m in length at traffic-orientated sites or an area of at least 250mx 250m at industrial sites.U.K.
3. Sampling points in urban background locations must be located so that their pollution level is influenced by the combined contribution from all sources upwind of the station. The pollution level should not be dominated by a single source unless such a situation is typical for a larger urban area. Those sampling points must, as a general rule, be representative for several square kilometres.U.K.
4. Where the objective is to assess rural background levels, the sampling point must not be influenced by agglomerations or industrial sites in its vicinity, i.e. closer than five kilometres.U.K.
5. Where contributions from industrial sources are to be assessed, at least one sampling point must be installed downwind of the source in the nearest residential area. Where the background concentration is not known, an additional sampling point must be situated within the main wind direction.U.K.
6. Sampling points must also, where possible, be representative of similar locations not in their immediate vicinity.U.K.
7. Account must be taken of the need to locate sampling points on islands, where that is necessary for the protection of human health.U.K.
Protection of ecosystems and vegetation
8. Sampling points targeted at the protection of ecosystems or vegetation must be sited more than 20 km away from agglomerations or more than 5 km away from other built-up areas, industrial installations or motorways or major roads with traffic counts of more than 50,000 vehicles per day. The Secretary of State must locate sampling points so as to be representative of air quality in a surrounding area of at least 1000 km². A sampling point may be sited at a lesser distance or to be representative of air quality in a less extended area, taking account of geographical conditions or opportunities to protect particularly vulnerable areas. Account must be taken of the need to assess air quality on islands.U.K.
1. Insofar as is practicable, sampling points must be situated in accordance with the following criteria—
[F5(a)the flow around the inlet sampling probe must be unrestricted (free in an arc of at least 270° or, for sampling points at the building line, 180°) without any obstructions affecting the airflow in the vicinity of the inlet (that is to say some metres away from buildings, balconies, trees and other obstacles and at least 0.5 m from the nearest building in the case of sampling points representing air quality at the building line);
(b)the inlet sampling point must be between 1.5 m (the breathing zone) and 4 m above the ground unless the station is representative of a large area and higher siting is appropriate. Any derogations must be fully documented;]
(c)the inlet probe must not be positioned in the immediate vicinity of sources in order to avoid the direct intake of emissions unmixed with ambient air;
(d)the sampler's exhaust outlet must be positioned so that recirculation of exhaust air to the sampler inlet is avoided;
(e)in relation to the location of traffic-orientated samplers, sampling points must be at least 25 m from the edge of major junctions and no more than 10 m from the kerbside. [F6A “major junction” is a junction which interrupts the traffic flow and causes different emissions (due to vehicles stopping and starting) from the rest of the road.]

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.

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.
