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- (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 Organisins." 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 facility during a quarter in which toxicity monitoring
is required, the permittee will complete the information located at the top of the aquatic toxicity
(AT)test form indicating the facility name,permit number,pipe number, county, and the
Page 14
Permit NC0031011
month/year of the report with the notation of"No Flow"in the comment area of the form. The
report 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
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.
reported residual chlorine of the effluent toxicity sample must be measured and 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
Page l 5
Permit NC0031011 '
1. Reporting (Supersedes Part II, Section D. (2.) and Section E. (5.) (a)I
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 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 ori in the case of a new facility, on the last day of the month
following the commencement of discharge.
