Alabama Department of Environmental Management (ADEM) runs the NPDES program in Alabama under delegation from EPA Region 4, issuing and enforcing the discharge permits listed here. Klarifi tracks 253 permits held by publicly owned treatment plants in the state, with status, expiry, design flow and three-year compliance for each. Agency website →

An NPDES permit runs for five years. To keep discharging, a plant must apply for renewal at least 180 days before the expiry date, and the renewed permit usually arrives with tighter effluent limits, new monitoring requirements or a compliance schedule. That is why the year a permit expires is the year a plant starts budgeting for upgrades: nutrient removal, disinfection, capacity or controls.

Violations are counted over the last three years of monitoring reports.
