CMM permit (wastewater and atmospheric emissions)

Regulation number CMM 2008-47 applies throughout the CMM territory. Click here to consult the official list of cities part of the CMM.

The industrial wastewater discharge permit application must be completed using this form provided by the City of Montreal.

Completing this form requires the compilation of a variety of data, such as:

• Information relating to production, including a description of the production processes and equipment accompanied by a process diagram with mass balance and a factory layout plan.
• Information on water supply for the different needs of your operations: cooling, washing, process, heating, sanitary, fire, etc.
• Data on the various water discharges from the factory with an estimation of the maximum annual flow rates, water flow diagram, plan of the factory sewer networks and characterization of discharges into the sewer (sampling and analysis)
• Information on the storage of inputs, fuels and finished products and the management of residual materials produced as well as methods for preventing accidental spills.

If you want to know more about the Communauté métropolitaine de Montréal regulation on wastewater treatment (CMM 2008-47), consult the article on the Avizo blog.

The permit application relating to atmospheric emissions requires not only the qualitative description of the emission sources, but also the quantitative estimation of the emissions of contaminants in the atmosphere.

In the event that no characterization by sampling of stacks has been carried out, the city generally accepts theoretical calculations of contaminant emissions based on recognized reference sources, such as AP-42 from the american Environmental Protection Agency (EPA) or sample data from similar sources. The estimated contaminant emission rates make it possible to confirm that the plant’s discharges comply with the ambient air concentration limit values indicated in Table 3.01 of Regulation 2001-10 on atmospheric discharges of the Communauté métropolitaine de Montréal (CMM)
