This comment is regarding O. Reg. 63/16 and specifically dewatering. It would be helpful for professionals, the industry of dewatering as a whole, and likely for regulators if guidelines for discharge to the environment were established rather than the current 'as per a discharge plan prepared by a qualified person'. These discharge guidelines could guide a discharge plan prepared by a qualified person rather than the current regulations that provides little guidance on discharge to the environment, particularly when the water is considered free of human introduced contaminates. The guidelines could be similar to the soil, ground water and sediment standards (SCS Tables) and could be based on different land use, if discharge is to be near surface water or even if discharge is to be to surface water. Furthermore, these could be used in connection with the storm sewer bylaw limits to establish acceptable discharge water quality particularly where the storm sewer bylaw limits are limited.
