The Sewer Use bylaw…

The Sewer Use bylaw discharge limits are meant to protect the environment. Any proposal to change the limits must take the environment into account.
-any proposal to exempt residential drainage from meeting the sewer use by-law storm sewer discharge limits may have a negative impact on the environment. Cities would also be liable to any negative impacts to the environment and receiving waters.
-the MECP has stated that some Sewer Use storm sewer discharge limits are below Drinking Water standards. However, in some cases, the guidelines in PWQO are also below Drinking Water standards.
-the MECP has stated that some residential building foundations may exceed bylaw discharge limits even when they are discharging uncontaminated water. How does the MECP define uncontaminated water?
-Has the MECP considered that effect of concentrations of parameters that are naturally occuring (ie zinc, manganese) vs concentrations of parameters present due to industrial activities?
-in some cities, the Conservation Authorities are the experts on the municipality's receiving waters. Unfortunately, the Province has legislated that they are no longer permitted to comment on water quality. If cities are required to study their receiving waters, will they allow the Conservation Authorities to comment or assist with the work.
-if cities are required to study their receiving waters and develop their own discharge limits, some limits may be even lower than they are now. The discharge limits may also not be consistent throughout the province.
