NPDES Section Databases

This page contains information about the online databases used by the NPDES Section of the Iowa DNR. Please expand the sections below for more information on each database.

1 Individual NPDES and Operation Permits - Wastewater Permit Information Exchange

To proceed to WWPIE, please use the following link: Wastewater Permit Information Exchange (WWPIE)

WWPIE has three main functions:

  • providing public access to pdf versions of draft, draft amendment, and final individual NPDES and operation permits in Iowa
  • providing public notice of permit issuances and reissuances
  • allowing interested persons to register, save searches and receive draft and final permit notifications

In WWPIE, you may search for and view 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. ADA accessible versions of the permit documents can be made available as needed.

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 or available on WWPIE.

Persons interested in NPDES permitting in Iowa can register, save searches, and receive 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 use the WWPIE Registration and Notification Instructions or view the FAQ document in WWPIE for more information on registering, saving searches, and receiving notifications in WWPIE.

For questions on WWPIE, and to obtain accessible versions of documents, please contact courtney.cswercko@dnr.iowa.gov.

NPDES Databases - Time of Transfer Database

The Iowa DNR has launched its new online Time of Transfer (ToT) Database for the submittal and search of ToT inspection reports.

The ToT Database is located at: https://programs.iowadnr.gov/timeoftransfer

The new ToT Database allows certified ToT inspectors to login in and enter inspection reports online. All ToT inspection reports will be automatically transmitted to the DNR and the county where the property is located, and will be available to the public online upon submittal.

For more information on the ToT Database, please see the ToT Inspection Program Webpage.
