Industrial Waste Disposal Permits

Industrial Waste Disposal Permits (IWDPs) are subject to routine inspections and annual fees. If a violation notice is issued by one of our field inspectors, a full reply to the items requested must be submitted within the time allotted by the notice. If corrective action cannot be completed within the due date, the inspector who issued the notice must be contacted directly. Field inspectors are available for phone calls, Monday through Friday, 8 a.m. to 9:30 a.m. A listing of our field office and headquarters facilities is included in our contact page.

An IWDP is terminated when the person owning or operating the premises has filed a written request, and a field inspection has confirmed that all industrial wastewater producing operations have ceased. All pretreatment facilities must been permanently removed or closed before a permit can be canceled. If the pretreatment facilities are to be maintained for future use, a non-use permit must be obtained.
