Industrial General Permit Fact Sheet

X.H.1.e.iv) requires Dischargers to divert run-on from non-industrial sources and
manage storm water generated within the facility away from industrial materials
and erodible surfaces. Runoff reduction is required as an advanced BMP when
minimum BMPs are not adequate to comply with the TBELs. The 2008 MSGP
encouraged Dischargers to consult with EPA’s internet-based resources relating
to runoff management.7

g. Salt Storage Piles or Piles Containing Salt

Section 2.1.2.7 of the 2008 MSGP requires salt storage piles/piles containing salt
that may be discharged to be enclosed or covered and to use BMPs when the
salt is being used. This General Permit does not have a minimum BMP
specifically for salt storage, however it does require all stockpiled/stored
industrial materials be managed in a way to reduce or prevent industrial storm
water discharges of the stored/stockpiled pollutants. The good housekeeping
(Section X.H.1.a) and material handling and waste management (Section
X.H.1.d) minimum BMPs in this General Permit require that all materials readily
mobilized by storm water be covered, the minimization of handling of industrial
materials or wastes that can be readily mobilized by contact with storm water
during a storm event, and the diversion of run-on from stock piled materials.

h. Sector Specific Non-Numeric Effluent Limits

Section 2.1.2.8 of the 2008 MSGP requires Dischargers to achieve any additional
non-numeric limits stipulated in the relevant sector-specific section(s) of Part 8 of
the 2008 MSGP. This General Permit is not a sector-specific permit and does
not contain sector-specific non-numeric effluent limitations like the 2008 MSGP.
While this General Permit does not specify sector-specific BMPs, Dischargers
are required to select and implement BMPs for their specific facility to reduce or
prevent industrial storm water discharges of pollutants to comply with the
technology-based effluent limitations. In addition, sectors with applicable ELGs
must comply with those ELGs.

i. Employee Training Program

Section 2.1.2.9 of the 2008 MSGP requires all employees engaged in
industrial activities or the handling of industrial materials that may affect
storm water to obtain training covering implementation of this General
Permit. This General Permit (Section X.D.1 and X.H.1.f) requires a
facility to establish a Pollution Prevention Team (team members,
collectively) responsible for implementing permit requirements such as
the SWPPP, monitoring requirements, or BMPs.
