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 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).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 - LIMITED (QUARTERLY)
[15A NCAC 02B .0500 et seq.]
ACUTE TOXICITY MONITORING(EPISODIC)
Petroleum Bulk Storage
The Permittee shall conduct quarterly acute toxicity tests using protocols defined 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 t sts will be performed on a discharge event during each
quarter(January-March, April-June,J y-September, October-December.
Should there be no discharge [no flow] fr m the facility during a quarter in which toxicity monitoring is
required, the Permittee will complete the i formation located at the top of the aquatic toxicity(AT)test
form indicating the facility name,permit umber,pipe number, county, and the month/year of the report
with the notation of"No Flow"in the co ent area of the form. The report shall be submitted to the
Environmental Sciences Section at the ad ress cited below.
Page 4 of 7

Permit NC0052311
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,DWR Form AT-1 (original)is to be sent
to the following address:
Attention: North Carolina Division of Water Resources
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 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. (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,
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 eD14IR 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 he 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 Dir ctor. Duplicate signed copies shall be submitted to the
mailing address above.
Requests for temporary waivers from a NPDES electronic reporting requirements must be
submitted in writing to the Division f written approval at least sixty(60) days prior to the date the
facility would be required under this p it to begin using eDMR. Temporary waivers shall be valid
Page 6 of 7

Permit NC0052311
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
