§ 34-153. Spill prevention and slug control plans.

(a)

Nondomestic 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 user's expense. Spill prevention plans, including the facilities and the operating procedures, shall be approved by the control authority before construction of the facility.

(b)

Nondomestic users that store hazardous substances shall not contribute to the POTW after the effective date of this division unless a spill prevention plan has been approved by the control authority. Approval of such plans shall not relieve the user from complying with all other laws and regulations governing the use, storage and transportation of hazardous substances.

(1)

The control authority shall evaluate all new SIU's for the need for a slug control plan within a year of the industrial user being designated as a SIU. Each significant industrial user shall be evaluated at least once every two years, and other nondomestic users as necessary, to determine whether such user needs a plan to control slug discharges. If the control authority decides that a slug control plan is needed, the plan shall contain, at a minimum, the following elements:

a.

Description of discharge practices, including non-routine batch discharges;

b.

Description of stored chemicals;

c.

Procedures for immediately notifying the POTW of slug discharges, including any discharge that would violate a prohibition under section 34-148, with procedures for follow-up written notification within five days;

d.

If necessary, procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of industrial site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
