Environmental assessment of the air pollutant emissions from the Manitoba Hydro Thermal Generating Station at Brandon, Manitoba

Abstract

This paper presents an evaluation of the air pollutant emissions from the Brandon Generating Station. Emission rates were estimated using a materials balance of the combustion products versus the fly ash retained in the boilers and the dust collectors. Dispersion analyses were performed to determine the corresponding ground-level pollutant concentrations for a variety of meteorological conditions. The major air pollution problem was found to be high concentrations of suspended particulate matter in excess of the Manitoba and National Air Quality Maximum Acceptable levels. This problem exists under virtually all conditions at full load. A reduction of 90 to 95% in the particulate emissions is required to effect compliance with the air quality standards.
