Subject: NPDES Stormwater Permit Coverage Renewal
Duff -Norton
COC Number NCG030004
Mecklenburg County
Dear Permittee:
In response to your renewal application for continued coverage under stormwater General Permit NCG030000
the Division of Water Quality (DWQ) is forwarding herewith the reissued 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 (COC)
• A copy of General Permit NCG030000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements.
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event' beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last COC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice(http://portal.ncdenr.org/web/wg/ws/su/current-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Unit's website with the new General Permit. Please visit
http://Portal.ncdenr.ore,/web/wq/ws/su/npdessw (click on 'General Permits' tab) to review that information
for your specific General Permit carefully.

Some of the changes include:
Part II:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases.
• Sections 8, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections 8, C: A lower TSS benchmark of 50 mg/I for HQW, ORW, RNA and Tr Waters applies to these
more sensitive waters.
• Sections 8, C. The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections 8, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections e, C: The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. If you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at [phone].
Sincerely,

Dear Permittee:
Your facility is currently covered for stormwater discharge under General Permit NCG030000. This permit expires
on August 3l, 2002. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by late summer of 2002. 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 will be expiring. Enclosed you will find a General Permit Coverage Renewal
Application Form. The application must be completed and returned by March 4, 2002 in order to assure continued
coverage under the general permit.
Failure to request renewal within this time period 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 11 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 facilty 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.htmi
If the subject stormwater discharge to waters of the state has been terminated; please completethe enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will he notified when the
rescission process has been completed.
If you have any questions regarding the permit renewal procedures please contact Mike Parker of the Mooresville
Regional Office at 704-663-1699 or Bill Mills of the Central Office Stormwater Unit at [phone], ext. 548
