(A) Industrial users shall provide protection from accidental discharge of materials which may interfere with the POTW by developing spill prevention plans. Facilities necessary to implement these plans shall be provided and maintained at the owner's or industrial user's expense. Spill prevention plans, including the facilities and the operating procedures shall be approved by the POTW before construction of the facility.
(B) Industrial users that store hazardous substances shall not contribute to the POTW after the effective date of this chapter unless a spill prevention plan has been approved by the POTW. Approval of such plans shall not relieve the industrial user from complying with all other laws and regulations governing the use, storage, and transportation of hazardous substances.
(C) The POTW shall evaluate each significant industrial user at least once every two years, and other industrial users as necessary, to determine whether such user needs a plan to control slug discharges. If the POTW decides that a slug control plan is needed, the plan shall contain, at a minimum, the following elements:
(1) Description of discharge practices, including non-routine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the POTW of slug discharges, including any discharge that would violate a prohibition under § 51.15, with procedures for follow-up written notification within five days;
(4) If necessary, procedures to prevent adverse impact from accidental spill, including inspection, and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site run-off, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.
