Inspections must be conducted:
– (A) At least once every 7 calendar days, or
– (B) At least once every 14 calendar days
and within 24 hours of the end of a storm
event of 0.5 inches or greater
8
Phase II NPDES CGP Requirements
(Inspector Qualifications)
Inspections
must be conducted by
qualified personnel provided by the
operator or cooperatively by multiple
operators
Examples
of qualified personnel are the
preparer of the SWPPP or individuals
certified by a DHEC approved course
9
Phase II NPDES CGP Requirements
(Monthly Reports)


For projects disturbing 10 acres or more, copies of
a monthly report or the inspection forms (if they
include specified information) must be submitted
In lieu of submitting monthly reports, the reports
may be stored electronically in a manner (i.e. a
dedicated website) that DHEC personnel have
unlimited access to

MS4 NPDES Ph. II Permit Status



MS4 Ph. II Permit was issued in October of 2003
and was subsequently appealed.
The appeal was settled on December 28, 2005.
The new effective date for the MS4 permit is
March 1, 2006.


Applies to all counties and municipalities that
operate a storm water sewer system within an
“urbanized area”
An “urbanized area” is one in which the
combined population of a county and an
adjoining or neighboring city is over 50,000
“Urbanized areas” can extend over county lines
