Watershed Management through Risk Based Effluent Criteria
Abstract:The Ontario Ministry of the Environment sets wastewater treatment plant effluent standards for five criteria: Recently, the Canadian Council of Ministers of the Environment (CCME) has developed a policy by which effluent criteria should be based upon risk-based standards.
Applying risk-based effluent criteria allows for the development of effluent limits and objectives which mitigate the effects of the wastewater discharges, as well as the other stresses on the water bodies on a site specific basis and results in a holistic overall watershed view of effluent parameters.
This paper explores the use of risk-based effluent standards to develop effluent limits and objectives and to offset impacts from non-regulated effluent parameters such as: personal care products and mitigating other stresses on the environment from stormwater discharges and potential climate change impacts are discussed.
