Overview

WPDES CAFO permits require proper manure management and ensure that adverse impacts to water quality do not occur. Permit applicants must submit detailed information about the operation, a manure management plan, plans and specifications for all manure storage facilities, and a completed environmental analysis questionnaire. Once a WPDES CAFO permit is issued, operators must comply with the terms of the permit by following approved construction specifications and manure spreading plans, conducting a monitoring and inspection program, and providing annual reports. See below for more details on WPDES Concentrated Animal Feeding Operation Permits.

For new or expanding operations, a permit application must be submitted at least 12 months before an operator expects to reach 1,000 animal units or more. It is essential that operators contact the DNR early on in the expansion planning process. This ensures that DNR review of regulated structures is completed prior to construction, that permitting concerns can be addressed as part of the planning process, and that the WPDES permit is issued before the operation expands beyond 1,000 animal units.

NOTE: If an operation currently has more than 1,000 animal units and does not have a WPDES permit, the owner or operator must contact the DNR immediately.

It is the responsibility of the owner or operator to request an application from the DNR. Enforcement actions could result for those who do not apply but are found to have 1,000 animal units or more. See below for more details on the WPDES CAFO permit process.
