This bill would require Department of Environmental Quality (DEQ) to review and rewrite water quality rules related to non-degradation requirements that may impact subdivisions and the effects they may pose from wastewater discharges to groundwater and surface water. There are already extensive rules and statutes governing this issue specifically trying to prevent degredation of high quality waters from pollution. Montana’s Water Quality Act (WQA) requires the DEQ to protect high quality of state water from degradation at levels to adequately protect, and prevent degradation our natural resources. The non-degradation rules apply to any activity that may affect the quality of surface or ground water. This bill directs DEQ to write new rules that are based on a generic distance between a septic systems discharge to groundwater and surface water. This analysis should be based on science, as is currently the case.
