Permit NC0081469
A. (2.) FLOW MEASUREMENT RATIONAL
[G.S. 143-215.1(b)]
The Rational Method-Determination of Peak Runoff:
[REF: FHWA Urban Drainage Design Manual, 3.2.2.Rational Method(3-1)]
Q=KuCIA,where:
Q = flow(peak flow rate in cfs or m3/sec)
Ku= unit conversation factor= 1.008 for U.S. standard units(usually
ignored because it is so close to 1), or 0.278 for metric units
C = dimensionless runoff coefficient for the watershed,loosely defmed 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).tc=time of concentration(time after beginning rainfall excess
when all portions of the drainage basin are contributing simultaneously to
outlet flow).
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.
•
A. (3.)ACUTE TOXICITY MONITORING- (QUARTERLY)
[15A NCAC 02B .0500 et seq.]
ACUTE TOXICITY MONITORING(EPISODIC)
Petroleum Bulk Storage
The permittee shall conduct quarterly acute toxicity tests using protocols defmed as definitive in E.P.A.
Document EPA/600/4-90/027 entitled"Methods for Measuring the Acute Toxicity of Effluents to Freshwater and
Marine Organisms." The monitoring shall be performed as a Fathead Minnow(Pimephales promelas)24-hour
static test. Effluent samples for self-monitoring purposes must be obtained below all waste treatment. The tests
will be performed on a discharge event during each quarter(January-March,April-June,July-September,
October-December).
Should there be no discharge of flow from the acility during a quarter in which toxicity monitoring is required,
the permittee will complete the information to ted at the top of the aquatic toxicity(AT)test form indicating the
facility name,permit number,pipe number,co ty, and the month/year of the report with the notation of"No
Flow"in the comment area of the form.The r rt shall be submitted to the Environmental Sciences Section at
the address cited below.
The parameter code for this test is TAE6C.All toxicity testing results required as part of this permit condition
will be entered on the Effluent Discharge Form(MR-1) for the month in which it was performed,using the
appropriate parameter code. Additionally,DWQ Form AT-1 (original)is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Page 4 of 7
Permit NC0081469
Environmental Sciences Section
1621 Mail Service Center
Raleigh,N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 performed by the North Carolina Division
of Water Quality 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. (4.) ELECTRONIC REPORTING- DISCHARGE MONITORING REPORTS
[NCGS 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 intends to
adopt and implement these regulations in 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit(Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting [Supersedes Part II,Section D. (2.) and Section E. (5.) (a)1
Beginning no later than 90 days from the effective date of this permit, the Permittee shall begin
reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) 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,
Page 5 of 7
Permit NC0081469
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR/DWR/ Information Processing Unit
ATTENTION: Central Files/eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a Permittee 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 reporting 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
electronically to the Division unless the Permittee re-applies for and is granted a new temporary
waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
2. Signatory Requirements [Supplements Part II, Section B. (11.)(b) and supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall make
the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION
WILL BE ACCEPTED:

direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the information,
the information submitted is, to the best of my knowledge and belief true, accurate, and complete. I
am aware that there are significant penalties for submitting false information, including the
possibility of fines and imprisonment for knowing violations."
3. Records Retention [Supplements Part IL Section D.(6.11
The Permittee shall retain records of all Discharge Monitoring Reports,including eDMR submissions. These
records or copies shall be maintained for a period of at least 3 years from the date of the report. This period
may be extended by request of the Director at any time[40 CFR 122.411

Facility Summary
This facility distributes high-volume hydrocarbon fuels to Raleigh Durham Airport (RDU) and,
therefore, has historically been permitted under an individual NPDES permit. This facility's
stormwater discharges are reported to occur on average once (1) to twice (2) per year.
Turbidity
The Stream Segment 27-33 (3.5) is not listed on the Final 2016 Category 5 Assessment 303 (d) list
for turbidity.
Toxicity- WET Testing- This permit requires Acute Whole Effluent Toxicity(WET) testing using
Fathead Minnow (Pimephales promelas), 24-hr definitive, LC-50 >100% [TAE6C]. Since last
renewal (June 2008) the Permittee reports all WET testing at Outfall 001 as "PASS" in 5 of 5
annual sample events. Acute WET testing monitoring frequency was relaxed to Annual prior to
the previous permit cycle—no changes recommended.
