Last week, the state Department of Ecology took one more step toward cleaning up the Spokane River by submitting a cleanup plan 12 years in the making to theEnvironmental Protection Agency. Officially called the Spokane River/Lake Spokane Dissolved Oxygen Water Quality Improvement Plan (referred to as the TMDL report on the street), the plan would bring our local bodies of water into compliance with allowable dissolved oxygen levels. When all is said and done, it calls for reduction of municipal and industrial phosphorous pollution — which leads to dissolved oxygen — by more than 90 percent. The EPA has 30 days to review the plan.
