Air Quality

Air Quality

The information for this section was obtained in June, 1995 from Kevin Stuart of The Health & Safety Office, and Dave Churchill of Plant Operations. To view this section of the CEAR Questionnaire Click here.

Federal Air Quality Standards: Federal air quality standards are maintained by UW and the City of Waterloo in that the quantities of air emissions produced are non-detectable. Regulations governing air quality at UW are set out in Regulation 308 - Environmental Protection Act (Ministry of Attorney General,1990) and the Occupational Health and Safety Act section on Air Quality. U.S. Standards set by the Environmental Protection Agency are also followed here at UW.

Stationary Sources of Air Pollution:

Two years ago there was an incinerator for bio-medical waste produced on campus, but this practice was terminated for reasons of cost.

Quantities of Air Pollution: No attempt has been made to calculate totals because emissions from UW operations are negligable, they are below exceedance levels.

Common Pollutants: The most common stationary and mobile pollutant on campus is Carbon Dioxide.

Air Pollution Reduction Programs: UW attempts to reduce air pollutants from stationary sources. UW uses carbon dioxide monitors to minimize ventilation use or maximize ventilation use. Carbon dioxide monitors currently exist in the Environmental Studies 2 building. Also, minimum Oxygen is used for burning in order to minimize nitrous oxide levels.

Programs for Ozone-Depleting Compounds: Currently, Freon 11, 22, and 12 are used in cooling systems and refrigerators on campus. However, UW uses a compressor unit which captures Freon. A Vaccum is used to empty the cooling systems and store the Freon in a presurized containment unit. This results in high efficiency air removal which minimized Freon loss when air is removed from the system. There is also a consultant who is currently working on the development of conversion plans.
