Footnotes:
1. No later than 270 days from the effective date of this permit, the permittee shall begin
submitting discharge monitoring reparts electronically using the Division's eDMR
application system [see A. (4)].
2. Flow shall be monitored with each discharge event — During periods of no flow, the
Permittee shall submit a signed, monthly Discharge Monitoring Report (DMR) indicating
"No discharge." Flow may be monitored using any one of four methods:
a) measure flow continuously (via flow meter, totalizer preferred);
b) calculate flow (see Rational Equation ) based on total rainfall per
unit area draining to the outfall [see A. (3.)];
c) estimate flow at 20 -minute intervals during the entire discharge
event; or
d) report flow based on discharge pump logs.
3. This sample to be collected concurrently with annual Acute Toxicity,

Pei7nit NC0046531
4. Turbidity — Effluent shall not cause receiving stream turbidity to exceed 50 NTU. If receiving -stream
background exceeds 50 NTU, the effluent shall not increase background levels. Non-compliance with this
Standard may require additional stream monitoring and a Turbidity Corrective Action Plan (TCAP).
5. Naphthalene — Provided that the Permittee can demonstrate to the Division that its facility does not now,
nor has ever, stored diesel fuel or other heavy fuels onsite, it may petition to remove this requirement from
the permit.
6. EPA Method 625- Once the facility has collected data for 12 consecutive sample events in which there
have been no detections above the method detection limit, the Permittee may request DWR to modify this
permit.
7. Acute Toxicity [TAE6C] Fathead Minnow (Pin7ephales promelas), 24 -hr definitive, LD50 >100%, Annual
[see A. (2.)].
Conditions:
• The Permittee shall discharge no floating solids or foam visible in other than trace amounts.
• The Permittee shall discharge no tank solids, tank bottom water, or the rag layer.
• Following hydrostatic testing, the Permittee shall discharge no tank (or pipe) contents unless benzene
concentration test less than 1.19 µg2 and toluene concentration test less than 11 µg2.

Permit NC0046531
A. (2.) ACUTE TOXICITY MONITORING (ANNUAL)
[15A NCAC 02B .0500 et seq.]
The permittee shall conduct acute toxicity tests on an annual basis using protocols defined as definitive
in EPA Document EPA -821-R-02-012 entitled "Methods for Measuring the Acute Toxicity of Effluents
and Receiving Waters to Freshwater and Marine Organi`sms." The monitoring shall be performed as a
Fathead Minnow (Pinnephales pronielas) 24 hour static test. Effluent samples for self-monitoring
purposes must be obtained during representative effluent discharge and shall be performed at the
NPDES permitted final effluent discharge below all waste treatment processes.
The parameter code for Pin�ephales pronZelas is TAE6C. All toxicity testing results required as part of
this permit condition will be entered on the Effluent Discharge Form (MR4) for the month in which it
was performed, using the appropriate parameter code. Additionally, DWR Form AT -1 (original) is to be
sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1623 Mail Service Center
Raleigh, North Carolina 27699-1623
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.
Should any test data from either these monitoring requirements or tests perfor�rrred by the North Carolina
Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival and appropriate environmental controls, shall constitute an invalid test and will
require immediate follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.

A. (3.) FLOW MEASUREMENT RATIONAL [G.S. 143-215.1(b)]
The Rational E uc action:
Q=KuCIA, where:
Pe�7nit NCO046531
Q = flow (peak now rate (cis or in /see)
Ku = units conversation factor = 1.008 for U.S. standard units (usually
ignored because it is so close to 1), or 0.278 for SI units
C = dimensionless runoff coefficient for the watershed, loosely defined
as the ratio of runoff to rainfall
I = intensity of rainfall taken from the intensity -duration -frequency
curves for the specified design return period at the time of
concentration, tc (in/h or mm/h). to = time of concentration (time
after the beginning of rainfall excess when all portions of the
drainage basin are contributing simultaneously to flow at the
outlet).
A = area of tributary watershed (acres or km2)
The rational equation is used to calculate the runoff from a region, given:
• the runoff coefficient (accounts for infiltration losses in the region),
• the rainfall intensity to the region,
• the time for runoff to travel from the region's upper reaches to its outlet, and
• the region's drainage area.

Permit NCO046531
A. (4.) ELECTRONIC REPORTING OF DISCHARGE MONITORING
REPORTS [G.S. 143-215.1(b)]
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (1 l.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)

reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous months) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
Following address:

1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permitt
ee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above.
Requests for temporary waivers from the NPDES electronic report
ing requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be valid
For twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
