Nevada Division of Environmental Protection (NDEP) runs the NPDES program in Nevada under delegation from EPA Region 9, issuing and enforcing the discharge permits listed here. Klarifi tracks 4 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.
