To proceed to WWPIE, please use the following link: Wastewater Permit Information Exchange (WWPIE)
WWPIE has two main functions:
In WWPIE, you may search for active individual NPDES and operation permits by proceeding to the search page. The facility pages in WWPIE provide basic information on permits, permit delay reasons (if applicable), and links to the permit documents. General Permits Nos. 1 - 9 are not included in WWPIE and facilities covered by these permits will not appear in the search. Only final and draft individual NPDES permits are included in WWPIE. Closed and revoked permits are not searchable.
Persons interested in NPDES permitting in Iowa can register, save searches, and recieve email notifications on draft and final permits in WWPIE. Registered users can opt to receive email notifications when individual permits are drafted or finalized in a specific search area, so users can be notified of new draft permits or can track permit issuance. Please view the FAQ document in WWPIE for more information on registering, saving searches, and receiving notifications in WWPIE.
For questions on WWPIE, please contact email@example.com.
