Reissuance or modification of CAFO WPDES permits

At least 180 days prior to the expiration of your current WPDES permit for a CAFO, you are required to submit a complete reissuance application to the Department of Natural Resources (DNR). Before submitting your reissuance application, please review the following reissuance instructions.

If you would like instructions and forms emailed to you or sent to you via the post office, please use the DNR addresses.

On-site compliance inspection and post-inspection letter

Prior to the deadline for your reissuance application submittal, your DNR regional agricultural specialist will conduct an on-site compliance inspection with you. The inspection determines whether the operation is in substantial compliance with the terms of the existing permit.

Following the compliance inspection, your regional agricultural specialist will send you a letter summarizing the inspection. The letter will specify any compliance activities requiring completion before a renewal is issued. The letter will also indicate whether the facility will be covered under a general or an individual permit and whether an Environmental Assessment is needed.
