How many wastewater permits expire in Nebraska in 2028?

32 NPDES permits held by publicly owned wastewater treatment plants in Nebraska expire in 2028, covering a combined average flow of 10 MGD. The busiest month is Jun 2028 with 10 expiries.

What happens when an NPDES permit expires?

The plant must have applied for renewal at least 180 days before the expiry date. If the agency has not reissued the permit by then, the old permit is administratively continued and stays enforceable. The reissued permit typically carries updated effluent limits based on the latest water-quality standards, which is what drives upgrade projects.

32 NPDES permits · 10 MGD combined average flow

32 publicly owned wastewater treatment plants in Nebraska hold NPDES permits that expire during 2028, issued by Nebraska Department of Water, Energy, and Environment. The table lists each plant with its permit number, expiry month, average flow, treatment technology and three-year violation count, in order of expiry.

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.
