The MOE recently issued amendments to O. Reg. 153/04 made under the Environmental Protection Act. In general, the amendments clarify the intent and scope of certain provisions, correct minor errors and incorporate new data. The amendments, among other things, make revisions to the MOE’s 2009 Soil, Ground Water and Sediment Standards to reflect current science and to correct errors, including revisions to certain petroleum hydrocarbon and sodium standards, and clarify that the use of potable ground water standards is necessary near wells that are used for human consumption or agriculture, but not necessary near wells that do not require potable water (e.g., dewatering wells).
