Stormwater Pollution Prevention Plan - Phoenix Sky Harbor ...

Non-mining MSGP 2010 General Permit
If circumstances change and industrial materials or activities become exposed to
stormwater or the facility becomes active and/or staffed, this exception no longer applies
and the permittee shall immediately resume visual assessments.
If, during the period of coverage under this permit, the facility becomes qualified for the
inactive and unstaffed exception, and there are no industrial materials or activities
exposed to stormwater, then the permittee shall include the same signed and certified
statement as above and retain it with the facility’s records pursuant to Part 5.4.
Except as provided by Part 8, permittees with inactive and unstaffed facilities that include
documentation with the SWPPP that they are unable to meet the “no industrial materials or
activities exposed to stormwater” standard shall conduct at least one visual assessment each
calendar year.
Substantially identical outfalls: If the facility has two or more outfalls that discharge substantially
identical pollutants, as documented in Part 5.1.5.2, the permittee may conduct visual
assessments of the discharge at just one of the outfalls and report that the results also apply to
the substantially identical outfall(s). If possible, visual assessments of each substantially identical
outfall shall be performed on a rotating basis throughout the period of coverage under this permit.
If a visual assessment performed on a sample collected at a substantially identical outfall
demonstrates that control measures are not functioning as intended, the permittee shall assess
and modify the control measures as appropriate for that outfall and, if necessary, other outfalls
represented by the monitored outfall.
4.3 Comprehensive Facility Inspections
4.3.1 Comprehensive Facility Inspection Procedures
The permittee shall conduct annual comprehensive facility inspections while covered under this
permit. Annual, as defined in this Part, means once per calendar year, but not within 6 months of the
previous inspection for the facility throughout the duration of permit coverage.
If the facility’s coverage is administratively continued after the expiration date of this permit, the
permittee shall continue to perform inspections annually until no longer covered by this permit.
A qualified person or persons shall conduct comprehensive facility inspections (CFI). A member
of the facility’s stormwater pollution prevention team shall conduct or participate in the inspection. CFIs
must cover all areas of the facility affected by the requirements in this permit, including areas identified in
the SWPPP as potential pollutant sources (see Part 5.1.3) where industrial materials or activities are
exposed to stormwater with the potential to discharge from the facility, any areas where control measures
are used to comply with the permit, and areas where significant spills (or spills that would contribute to the
discharge of pollutants in stormwater) and leaks have occurred in the past 3 years. CFIs must also
include a review of monitoring data collected in accordance with Part 6.2.
Inspectors must evaluate the results of the past year’s visual assessments and analytical
monitoring when planning and conducting inspections to determine potential areas of concern for
stormwater pollution. Inspectors shall look for the following:
Industrial materials, residue, or trash that may have or could come into contact with
stormwater;
Leaks or spills from industrial equipment, drums, tanks, and other containers;
Offsite tracking of industrial or waste materials, or sediment where vehicles enter or exit the
site;
Tracking or blowing of raw, final, or waste materials from areas of no exposure to exposed
areas; and
Control measures needing replacement, maintenance, or repair.
