4. Storm Water Pollution Prevention Plan (Continued)
(ii)For each area of the facility that
_- _ __ -. _ generates storm water discharges
associated with industrial activity
with a reasonable potential for
containing significant amounts of
pollutants, a prediction of the
direction of flow, and an
identification of the types of
pollutants which are likely to be
present in storm water discharges
associated with industrial activity.
Factors to consider include the
toxicity of chemical; quantity of
chemicals used, produced or discharged;
the likelihood of contact with storm
water; and history of significant leaks
or spills of toxic or hazardous
pollutants. Flows with a significant
potential for causing erosion shall be
identified.
(b) ~ventorv of BxgQaed Materials. An
