(A) The POTW manager shall evaluate whether each SIU needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The POTW manager will evaluate an SIU for a slug discharge control plan within the first year of determining that an IU is an SIU. If POTW manager determines that the SIU does not require a slug control plan, then the SIU will be evaluated every two years thereafter, for the need to develop a slug discharge control plan. The POTW manager may require any User to develop, submit for approval and implement such a plan or take such other action that may be necessary to control slug discharges.

(1) Description of discharge practices, including non-routine batch discharges;
(2) Description of stored chemicals;
(3) Procedures for immediately notifying the POTW manager of any accidental or slug discharge, as required by § 52.125 of this chapter; and
(4) Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to:
(a) Inspection and maintenance of storage areas;
(b) Handling and transfer of materials;
(c) Loading and unloading operations;
(d) Control of plant site runoff;
(e) Worker training;
(f) Building of containment structures or equipment;
(g) Measures for containing toxic organic pollutants, including solvents; and/or
