No. 486 STAATSKOERANT, 29 JUNIE 2012 DEPARTMENT OF ENVIRONMENTAL AFFAIRS NATIONAL ENVIRONMENTAL MANAGEMENT: AIR QUALITY ACT, 2004 (ACT NO. 39 OF 2004) No.35463 7 29 June 2012 NATIONAL AMBIENT AIR QUALITY STANDARD FOR PARTICULATE MATTER WITH AERODYNAMIC DIAMETER LESS THAN 2.5 MICRON METRES (PM2.5} I, Bomo Edith Edna Molewa, Minister of Water and Environmental Affairs, in terms of section 9(1) of the National Environmental Management: Air Quality Act, 2004 (Act No. 39 of 2004), hereby establishes the national ambient air quality standard for particulate matter of aerodynamic diameter less than 2.5 micron metre (PM2.s) as set out in the Schedule hereto. BOMO E ~~MOLEWA MINISTER OF WATER AND ENVIRONMENTAL AFFAIRS 8 No.35463 GOVERNMENT GAZETTE, 29 JUNE 2012 SCHEDULE 1. DEFINITIONS (1) In this notice, unless the context indicates otherwise, a word or expression to which a meaning has been assigned in the National Environmental Management: Air Quality Act, 2004, has the same meaning, and "averaging period" means a period over which an average value is determined; "compliance date" means the date on which compliance with the standard is required; and "frequency of exceedence" means a frequency (number/time) related to a limit value representing the tolerated exceedence of that limit value, i.e. if exceedences of limit value are within the tolerances, then there is still compliance with the standard. This exceedence is applicable to a calendar year. 2. GENERAL ( 1) Reference conditions Concentrations shall be expressed at a standardised temperature of. 25 oc and a pressure of 101,3 kPa. (2) Reference methods Where test methods are specified, any other method which can be demonstrated to give equivalent results may be used. (3) Ambient air quality measurement requirements Assessment of all ambient pollutant concentrations shall be conducted in terms of paragraph 5.2.1.3 of the National Framework for Air Quality Management in the Republic of South Africa.
