Résumé

This Regulation applies to municipal wastewater treatment works situated south of the 54th degree north latitude and whose average annual flow rate is greater than 10 m3 per day, including those situated on immovables comprised in a reserved area or in an agricultural zone established in accordance with the Act respecting the preservation of agricultural land and agricultural activities (chapter P-41.1). A municipal wastewater treatment works means any works used to collect, store, transport and process wastewater, in whole or in part of domestic origin, before being discharged into the environment, and operated by an intermunicipal board, a municipality or a person acting as a grantee for a municipality in accordance with section 43 of the Environment Quality Act (chapter Q-2) and section 22 of the Municipal Powers Act (chapter C-47.1). The operator of a treatment plant must measure the daily flow rate of wastewater treated by the plant with a device which can measure the flow rate with a margin of error less than 15% of the actual value. The device must be maintained in good working order at all times. It must also be calibrated at least once a year. Any sanitary, partially separated sanitary or combined sewer system must be connected to a treatment plant. The effluent from any treatment plant must comply with the following standards: (1) the 5-day carbonaceous biochemical oxygen demand (CBOD5) must be less than or equal to 25 mg/l; (2) the concentration of suspended solids (SS) must be less than or equal to 25 mg/l, except if it is shown that the excess is caused by algae proliferating in sewage lagoons; (3) the pH value must be between 6.0 and 9.5. Compliance of the concentrations provided for in subparagraphs 1 and 2 of the first paragraph is assessed periodically on the basis of an average effluent discharge calculated for the periods listed in Schedule I. The operator of a treatment plant must collect samples or take measurements of the effluent from its plant at the frequencies provided for in Schedule I and the operator must analyze them according to the procedure established in the Schedule.
