Subject: General Permit No. NCG130000 -Renewal
Queen City Transfer Station
COC No. NCG130079
Mecklenburg County
Dear Mr. Jones:
Please see the attached new Certificate of Coverage (COC) No. NCG130079 for renewed coverage
under Stormwater General Permit NCG130000 for this facility. This permit is reissued pursuant to
the requirements of North Carolina General Statute 143--215.:, 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.)
Renewed coverage under this General Permit is granted with the condition that the permittee
performs additional sampling requirements as outlined =n the amended conditions to the COC. This
COC requires you to sample each SDO semi-annually for total suspended solids (TSS), non -polar
oil & grease (O&G), fecal coliform, chemical oxygen demand (COD), copper (Cu), zinc (Zn),
and pH. Benchmarks are specified where applicable, and you must follow Tiered Response actions
in the event of a benchmark exceedance as specified in the General Permit (Part 11, p. 7 of 9). Please
note that monitoring at your site is required and not triggered only by on-site vehicle maintenance
activities or a certain amount of gallons of motor- oil/hydraulic oil used per month, as it is =or other
permittees under NCG130000.
The parameters include metals and other constituents which may be present in the discharge from this
site, based on sampling and recommendations by Charlotte -Mecklenburg Storm Water Services. The
Division will consider the data upon renewal of coverage under this General Permit to determine if
coverage under a different General Permit or an individual permit is more appropriate.
Nothing Compares...

The General Permit authorizes discharges of stormwater, and it specifies your obligations with
respect to discharge controls, management, monitoring, and record keeping. Please review the new
permit to familiarize yourself with all changes in the reissued permit. Your facility has six (6) months
from receipt of the permit to update your Stormwater Pollution Prevention Plan (SPPP) to reflect any
new permit requirements. Enclosed is a copy of the NCG130000 General Permit.
When does electronic DMR (eDMR) reporting start, and does it affect this permit?
Because this COC requires analytical mDnitoring, eDMR will affect you. We are setting up our
database with the outfalls that perm_ttees submitted on-line and permit parameters. Permittees will
receive notification when our eDMR system is ready for permit -holders to register and begin
reporting monitoring data electronically.
Your coverage under the General Permit -s transferable only through the specific action of
DEMLR. This permit does not affezt the legal requirements to obtain other permits which may be
required by the N.C. Department of Environmental Quality (DEQ), 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 concerning this permit, please contact Bethany Georgoulias at telephone
number [phone] or by email bethany.geor oulias@ncdenr. og_v.

Footnotes:
1 Measurement Frequency: Twice per year, during a measureable storm event.
2 Sample collection must begin within the fi-st 30 minutes of discharge.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted by NC Division of Energy, Mineral, and Land
Resources (DEMLR). A copy of the DEMLR letter granting ROS must be kept on site. DEMLR's ROS letter
remains in effect through the subsequent reissuance of this permit and as long as the pertinent site
conditions and operations remain unchanged, unless the ROS letter provides for other conditions or
duration.
4 For each sampled measureable storm event the total precipitation must be recorded from an on-site rain
gauge. (Where isolated sites are unmanned for extended periods, a local rain gauge reading may be
substituted for an on-site gauge, upon prior DEMLR written approval.)
5 The permittee shall compare monitor --ng results to the benchmark values. Exceedances of the benchmarks
require the permittee to increase mor_itor:ng, increase management actions, increase record keeping,
and/or install stormwater best management practices (BMPs) in accordance with the Tiered Response
actions outlined in Part I1, p. 7 of 9 in the General Permit (Tier One, Tier Two, and Tier Three). The pH
values should be within the range of 6.0-9 0 S.U. and must be measured in the field in accordance with
NPDES test procedure requirements in 40 CFR §136 (See Part I1I, Section D of the General Permit).
This certificate of coverage shall become effective June 1, 2018.
This Certificate of Coverage shall remain in effect for the duration of the General Permit.
