Adopted Rule

Rulemaking contact: Vanessa Rose, 541-278-4620 DEQ

The Environmental Quality Commission adopted rules that establish a Total Maximum Daily Load to address the impairments to water quality standards and beneficial uses in surface waters in the Powder River Basin. These impairments are caused by excess bacteria and will be addressed by identifying and quantifying sources of this pollutant. This rule also establishes a water quality management plan that includes pollutant management strategies, a list of parties responsible for developing management plans and implementing strategies, and a timeline to reduce pollutant loads and attain water quality standards.
