BROCK WEST LANDFILL

The effectiveness of control measures to eliminate odour problems was assessed at the Brock West municipal landfill in Pickering just east of Toronto, Ontario. Historical data on landfill operations and public complaints were examined, current control practices were evaluated and recommendations for controlling odorous emissions for future landfill operations were formulated. Field investigations included testing for fugitive gas emissions through the surface cover, odour sampling, and fugitive volatile organic emissions characterization.


COMBINED SEWER SURGE TANK

Odorous air samples were collected in the area surrounding the location of a proposed combined sewer surge tank. An odour panel determined the odour strength. Measurements at the source of the odours were used as input to an air dispersion model. The predictions were compared to measured odour concentrations at downwind locations. Odour complaint information was also used to assess the validity of the model. Potential odours from the proposed underground surge tank was assessed and compared with the existing situation.


Abatement - AWMA Paper

An overview of strategies for odour control was presented at the Air and Waste Management Associations annual conference. The presentation described a systematic approach to addressing odour impacts from initial complaint analysis through to the evaluation and selection of appropriate add?on control technologies.


PULP AND PAPER MILL

Historical odour complaints at a pulp and paper mill were used to evaluate the potential for particular emission sources to cause nuisance odours in St. John, New Brunswick. The location and frequency of occurrence was examined with respect to facility operations/upsets and with prevailing meteorological conditions. The complex coastal terrain in the vicinity of the mill was determined to be a major factor in affecting plume dispersion from the tall stacks of the mill.
