SUBJECT: Inspection-NPDES Stonnwater Compliance
Permit No. NCS000427
Dear Mr. Flynn: • I -
This document provides a summary of the compliance inspection conducted by the
Division of Water Quality on May 9, 2007. The Town of Cary has done an effective job
managing stormwater under the conditions of their permit. All of the six minimum measures
had innovative and effective measures that exceeded the permit requirements including the
Block Leader program, bi-annual surveys, detailed maps for tracking illicit discharge
detection and elimination program, ongoing dry weather stream walks and a very aggressive
and effective construction program. The Town recently completed a survey of municipal
operations and in the process of completing a comprehensive evaluation of municipal
operations, and although no deficiencies were observed the Town has taken the initiative to
upgrading stormwater pollution prevention measures.
During the inspection staff indicated that city buses are fueled at the Fleet
Maintenance facility. Coverage under the general permit, NCG08, is applicable to all owners
or operators of stormwater point source discharges associated with activities that have
vehicle maintenance areas, including fueling, associated with activities classified Local and
Suburban Transit and Interurban Highway Passenger Transportation. The Town has
submitted a Notice of Intent for coverage under NCG08 for the fleet maintenance facility. At
the time of the inspection, the state had not issued a certificate of coverage. However, the
Town has taken the initiative to develop and implement the permit requirements. Currently,
the Town is implementing components of a SWPPP for the facility under our Phase lI permit
issued in July 2005.
The Town of Cary has also taken the initiative to report all SSO's reaching
stormdrains or surface waters to the town's stonnwater section. The town took the initiative
to developed a process to ensure copies of spills and resolution, follow up reports and SSO
prevention and pre-treatment education and enforcement documentation are available to
regulatory officials for review. SSO's are being mapped on GIS and tracked for areas with
recurring issues that need further investigation and follow up.

The Town of Cary has also taken the initiative to ensure all land disturbing activities,
including municipal construction and maintenance projects that disturb less than 20,000
square feet that have a potential to impact water quality, are documented under work orders.
Under the initiative of the Town denuded areas, erosion control for the site, and stabilization
of the site will be documented.
The town's staff were very helpful during the inspection and should be commended
on the initiatives they've taken to managing stormwater under the conditions of their permit.
