In accordance with Wisconsin Statutes §283.53, the Department will be revoking and reissuing Heim's Hillcrest Dairy LLC's Wisconsin Pollutant Discharge Elimination System permit. This action is being taken because the facility has proposed a significant expansion that is expected to occur prior to the expiration of the current permit term. Under §283.53(2), the Department may modify, revoke and reissue, or terminate a permit if cause exists, including when a permittee plans significant alterations or additions to their facility or operations that may impact the characteristics of the discharge or the conditions of the permit. As a result, revocation and reissuance of the permit will allow the Department to evaluate the proposed expansion and ensure the permit conditions reflect the facility's updated operations and design. The Department has tentatively decided that the above specified WPDES permit should be reissued.
