Industrial General Permit Order

subsection H.1 below will not adequately reduce or prevent pollutants in
storm water discharges in compliance with Section V.A. Dischargers
shall identify any advanced BMPs, as described in subsection H.2
below, for those areas.

c. Based upon the assessment above, Dischargers shall identify any
drainage areas with no exposure to industrial activities and materials in
accordance with the definitions in Section XVII.

d. Based upon the assessment above, Dischargers shall identify any
additional parameters, beyond the required parameters in Section XI.B.6
that indicate the presence of pollutants in industrial storm water
discharges.

H. Best Management Practices (BMPs)

1. Minimum BMPs

The Discharger shall, to the extent feasible, implement and maintain all of
the following minimum BMPs to reduce or prevent pollutants in industrial
storm water discharges.12
a. Good Housekeeping

The Discharger shall:

i. Observe all outdoor areas associated with industrial activity; including
storm water discharge locations, drainage areas, conveyance
systems, waste handling/disposal areas, and perimeter areas
impacted by off-facility materials or storm water run-on to determine
housekeeping needs. Any identified debris, waste, spills, tracked
materials, or leaked materials shall be cleaned and disposed of
properly;

ii. Minimize or prevent material tracking;

iii. Minimize dust generated from industrial materials or activities;

iv. Ensure that all facility areas impacted by rinse/wash waters are
cleaned as soon as possible;

v. Cover all stored industrial materials that can be readily mobilized by
contact with storm water;

12 For the purposes of this General Permit, the requirement to implement BMPs “to the extent feasible” requires
Dischargers to select, design, install and implement BMPs that reduce or prevent discharges of pollutants in their
storm water discharge in a manner that reflects best industry practice considering technological availability and
economic practicability and achievability.
