The federal EPA has approved Wisconsin’s latest plan to reduce phosphorus pollution in the state’s waters. Under the new rules DNR determines the phosphorus discharge limits based on the condition and quality of a watershed. Limits can vary depending on whether a waterway is already impaired by phosphorus, among other factors. DNR can include a compliance schedule in its Clean Water Act permits if phosphorus discharge limits are either new or more stringent than in the past. The rule also allows new flexibility while pollution controls are being put in place, depending on the watershed. EPA has approved the rule as a revision to Wisconsin’s federally-approved National Pollutant Discharge Elimination System program under the Clean Water Act.
