Industrial General Permit Fact Sheet

concept by requiring four (4) nonstructural BMPs which include: identification and
inspection of equipment, observations of potential leaks in identified equipment,
an equipment maintenance schedule, and equipment maintenance procedures.

d. Spill and Leak Prevention and Response

Section 2.1.2.4 of the 2008 MSGP requires that Dischargers minimize the
potential for leaks, spills and other releases that may be exposed to storm water.
Dischargers are also required to develop a spill response plan which includes
procedures such as labeling of containers that are susceptible to a spill or a
leakage, establishing containment measures for such industrial materials,
procedures for stopping leaks/spills, and provisions for notification of the
appropriate personnel about any occurrence. This General Permit (Section
X.H.1.c) requires implementation of four (4) BMPs to address spills. These
BMPs include: developing a set of spill response procedures to minimize
spills/leaks, develop procedures to minimize the discharge of industrial materials
generated through spill/leaks, identifying/describing the equipment needed and
where it will be located at the facility, and identify/training appropriate spill
response personnel.

e. Erosion and Sediment Controls

Section 2.1.2.5 of the 2008 MSGP requires the use of structural and/or
non-structural control measures to stabilize exposed areas and contain
runoff. Also required is the use of a flow velocity dissipation device(s)
in outfall channels where necessary to reduce erosion and/or settle out
pollutants. This General Permit (Section X.H.1.e) requires the
implementation of (5) BMPs to prevent erosion and sediment
discharges. The erosion and sediment control BMPs include:
implementing effective wind erosion controls, providing for effective
stabilization of erodible areas prior to a forecasted storm event, site
entrance stabilization/prevent material tracking offsite and implement
perimeter controls, diversion of run-on and storm water generated from
within the facility away from all erodible materials, and ensuring
compliance with the design storm standards in Section X.H.6.
U.S. EPA has developed online resources for erosion and sediment
controls.6

f. Management of Runoff

Section 2.1.2.6 of the 2008 MSGP requires the diversion, infiltration, reuse,
containment, or otherwise reduction of storm water runoff, to minimize pollutants
in discharges. This General Permit (Sections X.H.1.a.viii, X.H.1.d.iv., and
