Subject: Stormwater Monitoring Results
Textile Rubber & Chemical Company at 2321 North Davidson Street
NPDES Stormwater/Permit NCG050000
Certificate of Coverage -- NCG050013
Mecklenburg County
Dear Mr. Davis:
Enclosed are the monitoring results from the laboratory analyses performed on the discharge from Stormwater
Outfall 001 and 002 at the subject facility. The samples analyzed were grab samples collected during the
sampling investigation performed on October 11, 2011, by Mrs. Aliyah Owens of Charlotte -Mecklenburg Storm
Water Services and included analyses required by the permit and additional analyses of interest in
stormwater discharges.
This sampling investigation was conducted as part of a cooperative working agreement between Mecklenburg
County and the Division of Water Quality. In addition, the inspection was conducted on behalf of the City of
Charlotte in compliance with the City's NPDES Permit, NCS000240, Part II Section H.
The enclosed monitoring results indicate that the concentrations of pollutants in the stormwater discharged on
October 11, 2011, were below the benchmark values contained in Stormwater general permit NCG050000.
However, elevated concentrations of enterococci, fecal coliform, total phosphorous, chemical oxygen demand
(COD), copper, and zinc were detected as compared with the Division's benchmarks developed for individual
stormwater permits (enterococci - 500 MPN/100 mL; fecal coliform —1,000 CFU/100 mL; total phosphorus — 2
mg/L; COD - 120 mg/L; copper — 7 pg/L; and zinc — 67 pg/L_)
Please review the requirements of your stormwater permit and take the required steps/actions to reduce the
concentration of the aforementioned items leaving your site. Through the development and implementation of
stormwater management programs it is the Division of Water Quality's expectation that stormwater discharges
at industrial sites covered by NPDES stormwater permits do not impact receiving waters.
The enclosed results should be self-explanatory; however should you have any questions concerning the
sampling results or have any questions regarding your permit, please do not hesitate to contact Mrs_ Aliyah

ADDENDUM
The National Pollutant Discharge Elimination System (NPDES) program was established under the federal
Clean Water Act and then delegated to the Division of Water Quality for implementation in North Carolina. The
NPDES permitting program for stormwater discharges was established in 1990. Phase I focuses on site and
operations planning to reduce pollutant sources.
Through the NPDES permitting program industrial facilities that fall into one of the subject ten categories are
required to obtain permit coverage under a general permit or an individual permit, depending upon the
facilities SIC code and the industrial activity occurring at the facility. There are currently 19 active general
stormwater permits in North Carolina. One condition that is applicable to both the general permits and
individual stormwater permits is the requirement to develop and implement site -specific comprehensive
Stormwater Pollution Prevention plans (SPPP). These plans are required to include a comprehensive
evaluation of the site and operations to reduce pollutant sources and prevent pollutant discharge.
Copies of the general permits and accompanying documents can be accessed from the following webpage:
http:Yportal.ncdenr.org/web/wqlws/su/npdessw#General_Permits_NPDES. Permit text, technical bulletins,
discharge monitoring forms, and a Notice of Intent [which is the application for coverage under a NPDES
General Stormwater Permit] can be found on this website.
The following items are a subset of permit requirements and are listed to assist you and help bring your
attention to certain permitting issues, process and condition requirements of your permit. Please see the
above mentioned website to obtain a copy of the permit so you may fully comply with all the conditions therein.
Failure to properly comply with conditions of the permit, like those bulleted below, is a violation(s) of
the permit and subject to civil penalty assessment(s) of up to $25,000.00 per day.
• Industrial facilities that fall into one of the subject ten categories are required to obtain permit coverage
under a general NPDES stormwater permit or an individual NPDES stormwater permit
• All persons desiring to have facilities covered by a General Permit must register with the Division of
Water Quality (DWQ) by filing of a Notice of Intent (NOI) and Applicable Fees.
• This Notice of Intent (NOI) must be submitted and a Certificate of Coverage issued prior to any
discharge of stormwater associated with the industrial activity, process wastewater, and/or mine
dewatering.
• Once the Notice of Intent is received, DWQ will review and determine whether a Certificate of Coverage
(COC) may be issued. If this Certificate of Coverage is issued the facility is covered by the General
Permit. That is, the permittee is authorized to discharge stormwater, process wastewater, and/or mine
dewatering pursuant to the type of General Permit until the permit expires or is modified or revoked.
• Any other point -source discharge to surface waters of the state is prohibited unless it is an allowable
non-stormwater discharge or is covered by another permit, authorization, or approval.
• There are currently 19 active general permits_ Permit conditions vary accordingly; however, most of the
permits have the following condition requirements (you must read your entire permit to ensure full
compliance):
o Development and compliance with the Stormwater Pollution Prevention Plan
o Collection, reporting, and recording of Analytical Monitoring
o Collection, reporting, and recording of Qualitative Monitoring

o Collection, reporting, and recording of Vehicle Maintenance Monitoring (if applicable)
o Records — Visual monitoring shall be documented and records maintained at the facility along
with the Stormwater Pollution Prevention Plan. Copies of the analytical monitoring results shall
also be maintained on site. The Permittee shall retain records of all monitoring information,
including all calibration and maintenance records and all original strip -chart recordings for
continuous monitoring instrumentation, and copies of all reports required by this general permit
for a period of at least 5 years from the date of the sample measurement, report, or application.
o Expiration — The permittee is not authorized to discharge after the expiration date of the general
permit. In order to receive automatic authorization to discharge beyond the expiration date, the
permittee shall submit forms and fees as are required by the agency authorized to issue permits
no later than 180-days prior to the expiration date. Any permittee that has not requested
renewal at least 180 days prior to expiration, or any permittee that does not have a permit after
the expiration and has not requested renewal at least 180 days prior to expiration, will be
subject to enforcement. Failure to renew your permit is a violation_
o Transfer — The Certificate of Coverage (COC) issued pursuant to this general permit is not
transferable to any person expect after notice to and approval by the Director. The Director may
require modification or revocation and reissuance of the Certificate of Coverage to change the
name and incorporate such other requirements as may be necessary under the Clean Water
Act. The Permit is NOT transferable.
o Name Change, Closure, or Facility Ownership change — Permittee is required to notify the
Division in writing in the event the permitted facility is sold or closed. The Division of Water
Quality views changes of name or ownership as -a modification that requires the Director's
approval and reissuance of the permit_ Name and ownership changes require you to complete a
Name/Ownership Change Form from the Division and mail it back to the Division of Water
Quality along with all appropriate information.
o Proper Operation and Maintenance is a requirement of the permit.
