Emissions Control
- 1972: Research to remove SO2 from flue gases continues.
- 1981: Coal-cleaning project completes first of four years of testing.
- 1984: Launch of acid gas control program and commitment to cutting emissions in half by 1990.
- 1986: “War on acid gas emissions” continues as Lakeview tests limestone-injection scrubbing technology to further reduce emissions, and uses more low-sulphur coal.
- 1987: The prospect of a major equipment overhaul looms, along with new environmental restrictions. Ontario Hydro begins three-year study aimed at obtaining approval for acid gas control equipment at coal-fired generating stations.
- 1989: Hydro announces a major Lakeview rehabilitation between 1990 and 1994, including the addition of acid gas control equipment on all eight units.
- 1991: Revised plan for Lakeview includes complete rehabilitation for Units 5 and 6, and a reduced rehabilitation for Units 1 and 2; decision on remaining four units deferred.
- 1992: High-efficiency precipitators are installed on all four operating units, which combined with flue gas conditioning technology to capture more than 99% of particulates in the flue gases.
- 1999: Lakeview receives ISO 14001 accreditation and announces new initiative to further reduce nitrogen oxide (NOx) emissions.
- 2001: Lakeview completes installation of new, low nitrogen oxide burners on all operating units, cutting nitrogen oxides emissions by 50% from the 1999 level.

Famous quotes containing the word control:
“There are many things children accept as “grown-up things” over when they have no control and for which they have no responsibility—for instance, weddings, having babies, buying houses, and driving cars. Parents who are separating really need to help their children put divorce on that grown-up list, so that children do not see themselves as the cause of their parents’ decision to live apart.”
—Fred Rogers (20th century)
