The “Alberta Ambient Air Quality Guidelines 111 ”, provide ambient environmental<br />
air quality objectives <strong>for</strong> Alberta.<br />
4.1.5. Manitoba<br />
Manitoba enacted a site-specific regulation 112 <strong>for</strong> Hudson Bay Mining & <strong>Smelting</strong><br />
and Inco Thompson to control emissions of particulate matter and sulphur<br />
dioxide. The regulation is titled “Inco Limited and Hudson Bay Mining and<br />
<strong>Smelting</strong> Co. Limited Smelter Complex Regulation Manitoba Reg. 165/88.<br />
Manitoba’s Objectives and Guidelines <strong>for</strong> Various Air Pollutants Ambient Air<br />
Quality Criteria provide ambient environmental air quality objectives <strong>for</strong> Manitoba.<br />
4.1.6. Ontario (Sudbury)<br />
Sulphur dioxide (SO 2 ) emissions from INCO Ltd. and Falconbridge Ltd. in<br />
Sudbury are regulated under orders issued by <strong>the</strong> Ministry of <strong>the</strong> Environment in<br />
1978, and revised in 1983 113 . Under <strong>the</strong>se orders, <strong>the</strong> companies are limited to a<br />
maximum hourly ground level concentration average of 0.5 parts per million<br />
(ppm) of SO 2 . On September 6, 2001, <strong>the</strong> Ministry of <strong>the</strong> Environment proposed<br />
new orders that became effective April 1, 2002. These require, among o<strong>the</strong>r<br />
things, Inco Ltd. and Falconbridge Ltd. smelter emissions to not exceed a<br />
maximum hourly ground level concentration of 0.34 ppm of SO 2 on a rolling<br />
hourly average basis. In addition, both facilities will have <strong>the</strong>ir annual SO 2<br />
emissions cap reduce by 34% by 2007 from <strong>the</strong> emissions cap set in 1994.<br />
4.1.7. Ontario (O<strong>the</strong>r)<br />
Ontario’s General - Air Pollution Regulation 114 (Environmental Protection Act<br />
R.R.O. 1990, Reg. 346) is designed to regulate most stationary sources of air<br />
pollution. The regulation requires that prescribed ambient air concentrations <strong>for</strong><br />
prescribed pollutants are met at <strong>the</strong> Point of Impingement (POI) as determined<br />
by atmospheric modelling protocols set out in <strong>the</strong> guidelines <strong>for</strong> <strong>the</strong>se substances<br />
are provided in <strong>the</strong> Summary of Point of Impingement Standards, Point of<br />
Impingement Guidelines and Ambient Air Quality Criteria (AAQCs) 115 .. The<br />
regulated party is required to meet <strong>the</strong> point of impingement limits through<br />
changes such as modifying process equipment, changing stack height, installing<br />
control equipment and/or switching to less harmful feed substances. The<br />
regulation also specifies opacity standards.<br />
