Why was the proposed instrument for ammonia changed?
Following extensive consultation with the provinces and territories and stakeholders, and the decision of the Canadian Council of Ministers of the Environment (CCME) to develop a Canada-wide Strategy for the management of municipal wastewater effluents by December 2006, Environment Canada decided to develop a CEPA Guideline for ammonia instead of a pollution prevention planning instrument. It remains the intention of Environment Canada to develop a management strategy that would include a regulation under the Fisheries Act based on a harmonized regulatory framework and common standards for specific pollutants, including ammonia and chlorine. The Guideline takes into account the comments received, the future development of a regulation, and the progress made in the development of a comprehensive Canada-wide Strategy. The Guideline also provides guidance for owners of wastewater systems that are consistent with a long-term management strategy for municipal wastewater effluents.
