Position on the Performance Standards of the Canada-wide Strategy for the Management of Municipal Wastewater Effluent
Canadian Council of Ministers of the Environment’s Canada-wide Strategy for the Management of Municipal Wastewater Effluent – Application of the Performance Standards
On February 17, 2009, the Canadian Council of Ministers of the Environment (CCME) adopted the Canada-wide Strategy for the Management of Municipal Wastewater Effluent (the Strategy). Although Québec has not yet officially sanctioned the Strategy, it is important to be certain that criteria selected for new domestic wastewater treatment projects incorporate at a minimum, the performance standards established by the Strategy so as to not authorize projects that may become compromised in the near future.
Position of the Ministère
These are minimum standards. When justified by the establishment of more restrictive environmental discharge objectives (EDOs), taking into account the assimilative capacity of the receiving body of water, stricter discharge requirements may be set by the Ministère, taking into consideration available and economically feasible technologies.
These standards apply to effluent discharge at the wastewater treatment plant. They are not applicable to sewer overflows and are to be applied on the basis of average values measured over a period as defined in the Strategy. TSS may exceed the standard if exeedance is caused by algae.
All new domestic wastewater treatment projects and all modernization or capacity increase must be designed so as to meet these standards, at a minimum. This position does not apply however to projects involving the addition of equipment to allow for supplementary removal of a parameter, for example, adding disinfection or phosphorus removal.
To summarize, this position targets:
This position does not target:
 To clarify the current position, domestic wastewater includes wastewater from municipal, community, commercial and institutional sources, strictly domestic wastewater from industrial sources, and wastewater from isolated dwellings not covered by A Regulation respecting waste water disposal systems for isolated dwellings.
