Annual Reports / Informational Updates

Through the Clean Water Act, the Environmental Protection Agency (EPA) establised the Phase II regulations in 1999. The NPDES Phase II requires permit coverage for storm water discharges from small Ms4s in urbanized areas and construction activities that disturb between 1 and 5 acres of land. Within Michigan the program is managed by the Michigan Energy, Great Lakes & Environment (EGLE ). Under EGLE, Genesee County and the communities that have an urbanized area, have applied for and received permits called certificate of coverage. One of the requirements of this permit is submitting an annual report, due due every other year due April 1.
