Permit Fees / Discharge Factors
An annual waste management permit fee is calculated in accordance with the Waste Management Permit Fees Regulation (fees regulation) as the base fee of $100 plus the sum of contaminant fees for all contaninant discharges authorized by the permit. The quantity of each contaminant discharge authorized by a permit (calculated from the permitted flow, duration and frequency of the discharge multiplied by the concentration of the contaminant within the discharge) is multiplied by its respective fee-per-tonne from the schedules of the fees regulation.
If a permit does not specify the concentration of contaminants contained in an authorized discharge, 'discharge factors' are substituted as typical concentrations so that contaminant fees can be calculated (discharge factors are not used for compliance purposes). Where the units of the authorized discharge factors are not compatible with the units of the permitted flow, "substitute flows" are allowable (examples are rates of production, fuel consumption or fuel feed).
The use of discharge factors is authorized under the fees regulation for various discharge sources. They derive from the United States Environmental Protection Agency's Compilation of Air Pollutant Emission Factors, Volume 1: Stationary Point and Area Sources (AP-42), AIRS Facility Subsystem Source Classification Codes and Emission Factor Listing for Criteria Air Pollutants and from permit monitoring data and other published values for effluent discharges.
The following describes the discharge factors (in respective sectors) authorized for permitted discharge sources which do not have the concentration of contaminants specified. Note that separate sets of discharge factors are authorized for a given source for each pollution control device applied to the source.
