Dear Mr. Clifford:
On August 26, 2009, Gary Hudson of this office met with Russell Price to perform an

and updated on an annual basis.
3. Facility Site Review
Observations of the outfalls at the facility did not reveal any concerns. The site appeared very
clean and well managed

COC Number NCG070122
Davidson County
Dear Permittee:
In response to your renewal application for continued coverage under stormwater General Permit NCG070000 the Division of
Water Quality (DWQ) is forwarding herewith the reissued stormwater General Permit. This permit is reissued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between the state of North
Carolina and the U.S. Environmental Protection Agency, dated October 15, 2007 (or as subsequently amended.)
The following information is included with your permit package:
• A new Certificate of Coverage
• A copy of stormwater General Permit NCG070000
• A copy of a Technical Bulletin for the General Permit
• Five copies of the Discharge Monitoring Report (DMR) Form
• Five copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater only, and it specifies your obligations with respect to stormwater
discharge controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself with all
the changes in the reissued permit.
The more significant changes in the General Permit since the your last Certificate of Coverage include the following:
• Permit cover page — Coverage is expanded to include industrial activities similar to the categorically identified industries.
• Part I Section A — This part explains that the No Exposure Exclusion from permitting option may be available to the
permittee.
• Part II Section A — Several minor expansions and clarifications of the required content of the Stormwater Pollution
Prevention Plan have been added. Please be sure that your plan is updated to comply with the new requirements.
• Part II Section B — Qualitative monitoring must now be conducted during a representative storm event.
• Part II Section B — The permittee is required to keep a written record of his response to problems identified by his
qualitative monitoring observations.
• Part II Section C - For facilities with vehicle maintenance activities using more than 55 gallons of new motor oil per month,
new provisions require that discharges from the vehicle maintenance areas be sampled twice per year, and that the
sampling results be compared to new numerical benchmark values. (The previous cutoff concentrations have been
eliminated.)
• Part II Section C — For facilities with vehicle maintenance activities using more than 55 gallons of new motor oil per month,
new provisions require the permittee to execute Tier One and Tier Two response actions, based on the first benchmark
exceedence (Tier One) and the second consecutive benchmark exceedence (Tier Two). Tier Two requires that the
permittee institute monthly monitoring instead of twice -per -year monitoring, until three consecutive monitoring events
show no benchmark exceedences.
• Part II Section C — This part contains a new provision that four exceedences of any particular benchmark wilt trigger
increased DWQ involvement in the permittee's stormwater management and control actions. DWQ may direct the
permittee to apply for an individual permit, or may direct the implementation or installation of specific stormwater control
measures.

• Part 11 Section C - For facilities with vehicle maintenance activities using more than 55 gallons of new motor oil per month,
new provisions require that discharges from the vehicle maintenance areas be sampled twice per year, and that the
sampling results be compared to new numerical benchmark values. (The previous cutoff concentrations have been
eliminated.)
• Part 11 Section C — For facilities with vehicle maintenance activities using more than 55 gallons of new motor oil per month,
new provisions require the permittee to execute Tier One and Tier Two response actions, based on the first benchmark
exceedence (Tier One) and the second consecutive benchmark exceedence (Tier Two). Tier Two requires that the
permittee institute monthly monitoring instead of twice -per -year monitoring, until three consecutive monitoring events
show no benchmark exceedences.
• Part II Section C — This part contains a new provision that four exceedences of any particular benchmark will trigger
increased DWQ involvement in the permittee'9 stormwater management and control actions. DWQ may direct the
permittee to apply for an individual permit, or may direct the implementation or installation of specific stormwater control
measures.

Subject: Rescission of NPDES General Permit
Permit Number NCG170122
Carolina Mills, Inc — Catawba
Catawba County
Dear Mr. Lineberger:
Reference is made to your recent request for rescission of the subject NPDES General Permit. On the
returned annual fee invoice you state the subject facility has been sold and therefore you no longer require
coverage under the general permit. In accordance with your request, NPDES General Pernut
NCG170122 is rescinded, effective immediately.
Please be advised that this permit rescission is based wholly upon your statement that the activities which
would require general permit coverage at the site have ceased or been eliminated. Division staff has not
visited the site to obtain independent verification. Operating a treatment facility, discharging wastewater
or discharging specific types of stormwater to waters of the State without a valid NPDES permit will
subject the responsible party to a civil penalty of up to $25,000 per day. Enforcement action will be
certain for persons that have voluntarily relinquished permit coverage when, in fact, continuing permit
coverage was necessary. If, in retrospect, you feel the site still requires permit coverage, you should
notify this office immediately. Furthermore, if in the future you wish to again discharge to the State's
surface waters, you must first apply for and receive a new NPDES permit.
If you have questions about this matter, please contact Bob Sledge at [phone], extension 547 or
the Water Quality staff in our Mooresville Regional Office at [phone].

Alan W. Klimek, P.E.

Hydro Conduit Corp-davidson
COC Number NCG070122
Davidson County
Dear Permittee:
Your facility is currently covered for stormwater discharge under General Permit NCG070000. This permit expires
on March 31, 2003, The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by early spring of 2003. Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit coverage will be expiring. Enclosed you will find a Permit Coverage Renewal
Application Form. The application must be completed and returned by October 2, 2002 in order to assure
continued coverage under the general permit. Due to staff and budget constraints, letters confirming our receipt of
the completed application will not be sent.
Failure to request renewal within the time period specified, may result in a civil assessment of at least $250.00,
Larger penalties may be assessed depending'on the delinquency of the request. Discharge of Stormwater from your
facility without coverage under a valid Stormwater NPDES permit would constitute a violation of NCGS 143-215.1
and could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the I I categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facility industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http://h2o.enr.state.nc.us/su/stormwater,html
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been compieted.
If you have any questions regarding the permit renewal procedures please contact Corey Basinger of the
Winston-Salem Regional Office at 336-771-4600 or Mack Wiggins of the Central Office Stormwater Unit at (919)
