Sec. 28-45.2. General significant industrial user permits.
A. The Director may use general permits to control significant industrial user discharges to the POTW if all facilities to be covered by the general permit:
1. Involve the same or substantially similar types of operations;
2. Discharge the same types of wastes;
3. Require the same effluent limitations;
4. Require the same or similar monitoring; and
5. As determined by the Director, are more appropriately controlled under a general permit than under individual wastewater discharge permits.
B. To be covered by a general permit, the significant industrial user must file a written request for coverage with the Department that identifies:
1. Its contact information;
2. Production processes;
3. The types of wastes generated;
4. The location(s) for monitoring all wastes covered by the general permit; and
5. Any other information the Department deems appropriate.
C. The Director will retain a copy of the general permit, documentation to support the Department’s determination that a specific significant industrial user meets the criteria in subsection A of this section and applicable State regulations, and a copy of the user’s written request for coverage for three years after the expiration of the general permit.
D. The Director may not control a significant industrial user through a general permit where the facility is subject to production-based categorical pretreatment standards or categorical pretreatment standards expressed as mass of pollutant discharged per day or for industrial users whose limits are based on the combined waste stream formula in 40 CFR 403.6(E).
