In the case of a denial of a permit application by the county feedlot pollution control officer, the applicant must be informed in writing by the county of the reasons for denial and must be informed of appeal procedures under chapter 7001. The applicant shall retain all rights of fundamental fairness afforded by law and the applicant may make an appeal to the agency to review the county's action. The denial by a county shall be without prejudice to the applicant's right to an appearance before the agency to request a public hearing or to file a further application after revisions are made to meet objections specified as reasons for denial.
In order for a delegated county to revoke a permit, a copy of the permit together with a written justification for revocation must be submitted to the commissioner for review. The commissioner shall, after receipt of the justification for revocation from the county, review the matter within 60 days to determine compliance with applicable agency rules. The county must receive written approval of the permit revocation from the commissioner before taking action. If a revocation has been approved by the commissioner, the applicant must be informed in writing by the county of the reasons for revocation and the applicant shall retain all rights of appeal afforded under chapter 7001. Revocation without reissuance of the permit must follow the requirements under part 7001.0180.
An owner who obtains a construction short-form or interim permit is subject to enforcement action for construction or operation without a permit if the commissioner or county feedlot pollution control officer later determines that the animal feedlot or a manure storage area does not qualify for the construction short-form or interim permit that was issued and that the owner is required to apply for and obtain an SDS or NPDES permit.
All construction short-form and interim permits expire within 24 months of the date of issuance. If the work for which a construction short-form permit was issued is not complete upon expiration of the permit, the expiration date of the permit may be extended by no more than 24 months if the owner complies with items A and B. If the pollution hazard for which an interim permit was issued is not corrected upon expiration of the permit, the expiration date may be extended by no more than 90 days if:
the owner notifies the commissioner or county feedlot pollution control officer at least 90 days prior to the expiration of the permit. The notification shall include:
if the animal feedlot under construction or expansion will be capable of holding 500 animal units or more, or the manure storage area under construction or expansion will be capable of holding the manure produced by 500 animal units or more when completed, the notification requirements under part 7020.2000, subpart 4, on a form provided by the commissioner, submitted to the commissioner or delegated county feedlot pollution control officer.
