A. (2.) RATIONAL EQUATION - FOR CALCULATING FLOW
[G.S. 143-215.1(b)] [15A NCAC 02B .0400 et seq., 02B .0500 et seq.]
The Rational Equation is one method for calculating runoff; find references and information in DWR's
Stormwater BMP Manual, Chapter 3, "Stormwater Calculations,"by addressing the following website:
https://www.deq.nc.gov/water-quality/surfac e-water-protection/spu/spu-bmp-manual-
documents/bmpman-ch03-swcalc s-20090616-dwq-spu/download
The Rational Method- Determination of Peak Runoff:
[REF: FHWA Urban Drainage Design Manual, 3.2.2. Rational Method(3-1)]
(i.) 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 - (EPISODIC) (QUARTERLY)
[15A NCAC 02B .0200 et seq.] [15A NCAC 02B .0500 et seq.]
The Permittee shall conduct annual 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 multiple-concentration test.
Effluent samples for self-monitoring purposes must be obtained below all waste treatment. The
Permittee will conduct one test annually, with the annual period beginning in January of the calendar
year of the effective date of the permit. The Annual test requirement must be performed and reported by
June 30. If no discharge occurs by June 30, notification will be made to the Division by this date.
Toxicity testing will be performed on the next discharge event for the annual test requirement.
Page 4 of 8

NPDES Permit NC0088960
Should any annual toxicity test result in a "failure", the Permittee shall test each subsequent
discharge event until testing indicates "pass," after which Quarterly monitoring shall take place.
The Quarterly tests will be performed on a discharge event during each quarter(January-March,
April-June,July-September, October-December). If after a subsequent five (5) consecutive Quarterly
WET tests indicate "Pass," the Permittee may petition the Division to change the monitoring back to
annual. If no petition is made, the toxicity testing frequency will be reviewed during the next permit
renewal.
Should there be no discharge [no 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 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, 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
1621 Mail Service Center
Raleigh,N.C. 27699-1621
Or, results can be sent to the email, ATForms.ATBAdeq.nc.gov.
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.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately until such time that a single test is passed. Upon passing,
this monthly test requirement will revert to quarterly in the months specified above. Assessment of
toxicity compliance is based on the toxicity testing quarter, which is the three-month time interval that
begins on the first day of the month in which toxicity testing is required by this permit and continues
until the final day of the third month.
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 OF DISCHARGE MONITORING
REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
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 Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report 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. The eDMR system may be accessed at:
https://deq.nc.gov/about/divisions/water-resources/edmr.
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 following address:
NC DEQ /Division of Water Resources /Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
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.
Starting on December 21, 2025, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.

NPDES Permit NC0088960
The permittee may seek an electronic reporting waiver from the Division (see"How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of
each electronic submission. The permittee should use the EPA's website resources to identify the initial
recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for
receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each
type of electronic submission and for each state. Instructions on how to access and use the appropriate
electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting
Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the
Division. Requests for temporary electronic reporting waivers 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 submitting monitoring data and reports. The duration of a temporary waiver
shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be
submitted electronically to the Division unless the permittee re-applies for and is granted a new
temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not
transferrable. Only permittees with an approved reporting waiver request may submit monitoring data
and reports on paper to the Division for the period that the approved reporting waiver request is
effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on the
following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements 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
