At least once every two years, the Director shall evaluate whether
each significant industrial user needs an accidental discharge/slug
control plan. The Director may require any user to develop, submit
for approval, and implement such a plan. Alternatively, the Director
may develop such a plan for any user. An accidental discharge/slug
control plan shall address, at a minimum, the following:
A. Description of discharge practices, including nonroutine batch discharges.
B. Description of stored chemicals.
C. Procedures for immediately notifying the Director of any accidental or slug discharge, as required by §
450-75 of this Part
4.
D. Procedures to prevent adverse impact from any accidental or slug
discharge. Such procedures include but are not limited to inspection
and maintenance of storage areas, handling and transfer of materials,
loading and unloading operations, control of plant 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.
