Western Australia Environmental Protection Act 1986 2 Clean Air (Determination of Air Impurities in Gases Discharged to the Atmosphere) Regulations 1983

1. Citation These regulations may be cited as the Clean Air (Determination of Air Impurities in Gases Discharged to the Atmosphere) Regulations 1983 1.

2. Interpretation In these regulations unless the contrary intention appears — boiler means any vessel in which for any purpose water is heated by any combustion material with a total heat input of 100 or more megajoules per hour; cubic metre means that volume of dry gas which occupies a cubic metre at a temperature of 0° Celsius and at an absolute pressure equivalent to one atmosphere; dark smoke means smoke that, if compared with charts known as the Ringelmann Chart or Miniature Ringelmann Chart described in regulation 5(7), would appear darker than shade 1 on either of those charts; flue or duct means any exhaust, flue, duct, structure or opening from or through which air impurities are or are likely to be emitted to the atmosphere. [Regulation 2 amended: Gazette 21 Jun 1985 p. 2201.]

3. Standard of concentration For the purposes of section 33(1) of the Act 3, in respect of — (a) any boiler or incinerator emitting solid particles — the standard of concentration at the point of emission determined in accordance with regulation 4(2), of solid particles in residual gases, adjusted to a basis of 12% carbon dioxide shall be 0.25 g/m3; (b) any other trade, industry, process, industrial plant or fuel burning equipment emitting solid particles not mentioned in paragraph (a) — the standard of concentration at the point of emission, determined in accordance with regulation 4(2) of these regulations of solid particles in residual gases before admixture with air, smoke or other gases shall be 0.25 g/m3.
