Industrial waste discharge permits or control mechanisms are issued to a specific user for a specific operation. Control mechanisms shall not be reassigned or transferred or sold to a new owner, new user, different premises, or a new or changed operation without the approval of the WRD Manager and provision of a copy of the existing control mechanism to the new owner/user. If no changes are made to the operation by the new owner, the approval shall be completed within 30 days. Certification by the new owner or new user that no significant changes in operation have occurred may be required. If modifications are made in the operation, or if a new use of the premises is planned by the new user, a control mechanism modification or issuance of a new control mechanism shall be required.
