Industrial General Permit Order

alternative BMP or suite of BMPs. The alternative BMPs shall be
designed to achieve the same or better performance standard as a 1mm
mesh screen with a treatment capacity of the peak flow rate from a one-
year, one-hour storm. Alternative BMPs shall be submitted to the
Regional Water Board for approval.

c. Plastics Facilities shall use durable sealed containers designed not to
rupture under typical loading and unloading activities at all points of
plastic transfer and storage.

d. Plastics Facilities shall use capture devices as a form of secondary
containment during transfers, loading, or unloading Plastic Materials.
Examples of capture devices for secondary containment include, but are
not limited to catch pans, tarps, berms or any other device that collects
errant material.

e. Plastics Facilities shall have a vacuum or vacuum-type system for quick
cleanup of fugitive plastic material available for employees.

f. Pursuant to Water Code section 13367(e)(1), Plastics Facilities that
handle Plastic Materials smaller than 1mm in size shall develop a
containment system designed to trap the smallest plastic material
handled at the facility with a treatment capacity of at least the peak flow
rate from a one-year, one-hour storm, or develop a feasible alternative
BMP or suite of BMPs that are designed to achieve a similar or better
performance standard that shall be submitted to the Regional Water
Board for approval.

2. Plastics Facilities are exempt from the Water Code requirement to install a
containment system under section 13367 of the Water Code if they meet
one of the following requirements that are determined to be equal to, or
exceed the performance requirements of a containment system:

a. The Discharger has certified and submitted via SMARTS a valid No
Exposure Certification (NEC) in accordance with Section XVII; or

b. Plastics Facilities are exempt from installing a containment system, if the
following suite of eight (8) BMPs is implemented. This combination of
BMPs is considered to reduce or prevent the discharge of plastics at a
performance level equivalent to or better than the 1mm mesh and flow
standard in Water Code section 13367(e)(1).

i. Plastics Facilities shall annually train employees handling Plastic
Materials. Training shall include environmental hazards of plastic
discharges, employee responsibility for corrective actions to prevent
errant Plastic Materials, and standard procedures for containing,
cleaning, and disposing of errant Plastic Materials.
