Draft ambient water quality criteria recommendations for lakes and reservoirs of the conterminous United States. These draft national criteria recommendations are models for total nitrogen and total phosphorus concentrations in lakes and reservoirs to protect three different designated uses—aquatic life, recreation, and drinking water source protection—from the adverse effects of nutrient pollution. These draft criteria recommendations are based on stressor response models, which link nutrient pollution stressors (nitrogen, phosphorus) to responses associated with protection of designated uses. These draft criteria recommendations, when finalized, will replace the EPA’s previously recommended ambient nutrient criteria for lakes and reservoirs. Comments must be received on or before

State formula allocations for sewer overflow and stormwater reuse. The U.S. Environmental Protection Agency (EPA) is announcing the proposed allotment formula for the Sewer Overflow and Stormwater Reuse Municipal Grants Program as required by the Clean Water Act. In order to determine the proportional needs of each state and distribute funds on a more equitable basis, EPA’s proposed allocation formula has identified additional factors and assigned weights respective to each. The bulk of the allocation weight rests on the Clean Watersheds Needs Survey (50%). A state’s annual average precipitation, total population, and urban population equally share in the remaining 50% and are weighted at 16.67% each. Comments on the proposed formula must be submitted by Sept. 3, 2020.
Notice of availability of the draft Shell Rock River Watershed Total Maximum Daily Load (TMDL) and Watershed Restoration and Protection Strategy (WRAPS) reports and request for comment. Public comment period ends at 4:30 p.m. Sept. 25, 2020.
