Relevant Periods
     3.  - (1) The relevant period for the purposes of Article 13(4) of the Order shall be, in relation to the preparation of an action plan to which that Article applies, the period of 3 months beginning with the date on which the district council preparing the action plan first consults the relevant authority in relation to the plan pursuant to Article 13(3) of the Order.

Air Quality Objectives
     4.  - (1) It is an air quality objective for each substance listed in the first column of the Table in the Schedule that the level at which that substance is present in the air is restricted to a level set out in the second column of that Table for that substance by no later than the date set out in the third column of that Table for that substance and level.

    (2) The achievement or likely achievement of an air quality objective prescribed by paragraph (1) shall be determined by reference to the quality of air at locations -

     40µg/m3 when expressed as an annual mean 31 December 2004

*µg/m3: micrograms per cubic metre

ppb/ppm: parts per billion/million

mg/m3: milligrams per cubic metre

Interpretation
For the purposes of this schedule:-

     1. "PM10" means particulate matter, which passes through a size-selective inlet with a 50% efficiency cut-off at 10µm aerodynamic diameter.

     2.  - (1) A running annual mean is a mean, which is calculated on an hourly basis, yielding one running annual mean per hour. The running annual mean for a particular substance at a particular location for a particular hour is the mean of the hourly levels for that substance at that location for that hour and the preceding 8759 hours.

    (2) For the purpose of the calculation of a running annual mean, the hourly level for a particular substance at a particular location is either -

     3.  - (1) A maximum daily running 8-hour mean is calculated on a daily basis. The maximum daily running 8-hour mean for a particular substance at a particular location for a particular day is the maximum of the running 8-hour means ending during that day.

    (2) For the purpose of sub-paragraph (1) a "running 8-hour mean" is a mean, which is calculated on an hourly basis, yielding one running 8 hour mean per hour. The running 8-hour mean for the relevant substance at the relevant location for a particular hour is the mean of the hourly means for the substance at the location for the hour and the preceding 7 hours.

     4.  - (1) An annual mean is a mean, which is calculated on a yearly basis, yielding one annual mean per calendar year. The annual mean for a particular substance at a particular location for a particular calendar year is -

    (2) For the purpose of the calculation of the annual mean for lead, the daily level for lead at a particular location for a particular day is the level at which lead is recorded as being present in the air at that location during the week in which the day occurs on the basis of a continuous sample of air taken throughout that week (each day in that week therefore being attributed with the same daily level).

    (3) For the purpose of sub-paragraph (2) "week" means a complete week beginning on a Monday, except that it also includes any period of less than seven days from the beginning of the calendar year until the first Monday in that year to the end of that year.

    (4) For the purpose of any calculation of the annual mean for benzene on the basis of the mean of the daily levels, the daily level for benzene at a particular location for a particular day is the level at which benzene is recorded as being present in the air at that location during the fortnight in which the day occurs on the basis of a continuous sample of air taken throughout that fortnight (each day in the fortnight therefore being attributed with the same daily level).

    (5) For the purpose of sub-paragraph (4) "fortnight" means a complete fortnight, that is a period of two weeks beginning on a Monday (no particular week in a calendar year being included in more than one fortnight), except that it also includes -

     5. An hourly mean is a mean calculated every hour. The hourly mean for a particular substance at a particular location for a particular hour is the mean of the levels recorded for that substance at that location -

     6. A 24-hour mean is a mean calculated every 24 hours. The 24 hour mean for a particular substance at a particular location for a particular 24 hour period is the level at which that substance is recorded as being present in the air at that location on the basis of a continuous sample of air taken throughout the period.

     7. A 15-minute mean is a mean calculated every 15 minutes. The 15 minute mean for a particular substance at a particular location for a particular 15 minutes is the mean of the levels recorded, at a frequency of not les than once every 10 seconds, for that substance at that location during that 15 minutes.

     8. The reference to a number of micrograms or milligrams per cubic metre of a substance is a reference to the number of micrograms or milligrams per cubic metre of that substance when measured with the volume standardised at a temperature of 293K and at a pressure of 101.3 kPa.


EXPLANATORY NOTE

(This is not part of the Regulations.)


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.

These Regulations prescribe the relevant period (regulation 2(2)) and set out the air quality objectives to be achieved by the end of that period (regulation 3 and the Schedule).

Where any of the prescribed objectives are not likely to be achieved within any part of a district council's area within the relevant period, the district council concerned will have to designate that part of its area as an air quality management area. An action plan covering the designated area will then have to be prepared setting out how the district council and prescribed relevant authority intend to exercise their powers in relation to the designated area in pursuit of the achievement of the prescribed objectives. The Regulations prescribe the period within which a prescribed relevant authority will have to submit proposals to a district councils, which is preparing an action plan within the district councils area (regulation 2(1)).
