Subject: Draft NPDES Permit NCO081469
RDU Delivery Facility
Class I - Physical -Chemical WPCS
Wake County
Attached with this letter is a copy of the Draft NPDES permit renewal for your facility. Please review
this draft carefully to ensure thorough understanding of the requirements and conditions it contains.
There are a few changes in the draft attached here from the existing permit. These changes are
summarized below.
• Regulatory Citations - Language has been added where necessary in the permit to provide regulatory
citations for permit requirements. This includes updates to citations that have been changed with
recent rule revisions.
• Electronic Reporting - Permit language has been modified to be consistent with the finalization of
federal requirements for electronic reporting.
• Addition of Permit Limits - Data from the previous permit cycle was evaluated under a
Reasonable Potential Analysis (RPA) to determine whether any pollutant has potential to
impact instream water quality. The RPA evaluation found that three parameters showed
reasonable potential and require the addition of a permit limit to assure no impacts to the
receiving waters. Permit limits have been added to your permit for Toluene (11 µg/L), Total
Recoverable Phenolics (300 µg/L) and Naphthalene (12 µg/L).
Implementation of these limits will be postponed until the next permit cycle (2028). A Schedule
of Compliance has been added in Section A. (5.) of the permit and is noted in Footnote 8, which
has been added to the Effluent Table. You are required to continue monitoring for these
parameters at the frequency specified in the permit during this permit cycle. This permit still
includes the limits for these parameters as an indication of the expectations for the next permit
renewal. The Schedule of Compliance includes requirements for annual reports on actions
taken in review, assessment and implementation toward meeting these limits down the road.

• Monitoring for the EPA Method 625 parameters - The permit language has been updated to
reflect EPA Method 625.1. A new footnote and Section associated with monitoring and
reporting for these methods have also been added (see info below).
• Footnotes have been added in the effluent table as noted below.
- Footnote 3 added addressing collecting oil and grease samples from a quiescent pool.
- Footnote 4 is added back to the permit to require collection of certain parameters
concurrently with WET sampling. Discussions with Division Aquatic Toxicology staff
verified having these samples concurrently can help isolate any potential toxicity issues.
- Footnote 5 has been added to assure that discharge does not cause the receiving stream to
exceed the 50 NTU standard.
- Footnote 6 has been added to reference an added Section addressing EPA Method 625.1
monitoring and reporting.
- Footnote 7 for Toxicity has been modified to include reference to the specific parameters
that WET testing should be done concurrently with.
- Footnote 8 was added to address a Schedule of Compliance for the new permit limits.
• Special Condition A.(2.) - This condition has been updated to be consistent with the required
annual WET requirements. The language also notes the ability to now submit AT forms
electronically. This was Section A.(3.) in the previous permit.
• Section A.(3.) - This was Section A.(2) in the previous permit.
• Section A.(4.) outlining specific monitoring and reporting requirements for Methods 624.1 and
625.1 has been added to the permit.
• Section A.(5.) outlining a Schedule of Compliance for new limits has been added to the permit.
• Section A.(6.) has been renumbered with the addition of new Sections A.(4.) and A.(5.).
• Permit Map - Map information has been updated.
The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included in this
draft document (cover, map, and Part 1). The conditions are the same as in your current permit. The latest
version of the standard conditions is available at https://bit.ly/3k5NFaL and can be viewed online or
downloaded as a PDF file.
Concurrent with this notification the Division is publishing a notice in a newspaper having general
circulation in the Wake County area soliciting public comments on this draft permit.
Please provide any written comments you may have to me no later than 30 days after receipt of this
draft permit

Footnotes:
1. The Permittee shall submit Monthly Discharge Monitoring Reports (DMRs) electronically in accord
with the Division's Electronic Discharge Monitoring Reporting (eDMR) Program [section A. (6.)].
2. Flow — During periods of no flow, the Permittee shall submit a monthly Discharge Monitoring Report (DMR)
indicating "No discharge." Flow shall be monitored at each discharge and may be monitored in one of four ways:
a. measure flow continuously;
b. Rational Method -- calculate flow [see Rational Equation — Section A. (3.)]
based on total rainfall per area including built -on area draining to the outfall;
c. estimate flow at 20-minute intervals during the entire discharge event; or
d. report flow based on discharge pump logs.
3. Oil and Grease — Where possible, the grab sample for oil and grease should be skimmed from the surface of
a quiescent (calm water) zone.
4. Samples for this analyte shall be collected concurrently with WET -Test sampling, appropriate to frequency.
5. Effluent shall not cause receiving stream turbidity to exceed 50 NTU. If receiving stream background turbidity
exceeds 50 NTU, effluent shall not cause this background value to increase.
6. See Section A.(4.) for additional monitoring and reporting requirements for EPA Methods 625.1.
7. Whole Effluent Toxicity (WET) Testing — Acute Annual WET testing will continue at this frequency provided that the
Permittee maintains WET test results showing "pass" [or LC50 > 100] for each annual event." If WET -test results show
"fail," the sampling frequency shall immediately revert to Quarterly in accord with Section A. (2.), and the Permittee will
not regain eligibility for Annual testing frequency except after five (5) consecutive quarters showing "Pass." WET testing
to be preformed concurrently with parameters in footnote 4 above.
8. Permit Limits for Toluene, Total Recoverable Phenolics and Naphthalene will not be effective for this permit cycle,
but monitoring will continue to be required. Permittee shall meet the Schedule of Compliance outlined in Section A.(5).
Conditions:
1. The Permittee shall discharge no floating solids or foam.
2. The Permittee shall discharge no tank or pipe solids, bottom water, or rag layer.
3. Following hydrostatic tank testing, the Permittee shall discharge no tank (or pipe) contents with
concentrations of benzene > 1.19 µg/L or toluene > 11 jig/L.

Draft Permit NCO081469
A. (2.) ACUTE TOXICITY MONITORING (EPISODIC)- LIMITED (ANNUAL)
[15A NCAC 02B 0.200]
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 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.
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.
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 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 Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Or, results can be sent to the email, [e-mail].
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.

Draft Permit NC0081469
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. (3.) FLOW MEASUREMENT RATIONAL METHOD
[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. (4.) ADDITIONAL MONITORING REQUIREMENTS
[G.S. 143-215.1(b)]
(a.) EPA Method 625.1— Base Neutrals & Acids (Semi-VOCO. The permittee shall conduct Monthly
effluent pollutant scans using protocols as defined in E.P.A. Document EPA 821-R-16-007 entitled
"Method 625.1: Base/Neutrals and Acids by GC/MS". The parameter code for reporting EPA Method
625.1 is 76028. Parameter codes for reporting analytes associated with this method are listed in EPA
Method 625.1: Tables 1, 2 and 3 below.
Page 5 of 14

Draft Permit NC0081469
(b.) Standard Conditions. Analytical methods shall be in accordance with 40 CFR Part 136 and shall be
sufficiently sensitive to determine whether parameters are present in concentrations greater than
applicable standards and criteria (See Part II. Section D). Laboratory reports shall be kept on file in
accordance with records retention requirements found in Part 11. Section D.
(c.) Effluent Scan Reporting.
• For the eDMR application system, under the parameter code for the pollutant scan, indicate whether
the test was performed by entering "1" for "yes" and "0" for "no".
• Any detection of analytes shall be entered in eDMR, using the appropriate parameter code listed in
the tables below. Once an analyte is detected, the parameter should be reported in eDMR at the
same monitoring frequency as the pollutant scan until further notice by the Division.
• Parameter codes noted with "+" in the tables below may not currently be allowed in eDMR and will
need to be added by the eDMR administrator. Please submit requests to add parameters to the
appropriate eDMR contacts with the Division.
• Any analytes in the tables below that do not have an assigned parameter code are noted as "No
Code". These parameters shall be noted in the comments section of eDMR by noting the analyte
detected, the CAS Registry No. and the reported concentration.
• A current List of Parameters Allowed for DMRs can be found at the following webpage:

accessed at: https:Hdeg.nc.aov/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.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
reported via the eDMR system no later than the last calendar day of the month following the
completed reporting period. 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.
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)].

Draft Permit NC0081469
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.federalre ig ster.gov/documents/20l5/lO/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:
hqp:Hdeq.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. (I 1.)(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:
hqp:Hdeq.nc.gov/about/divisions/water-resources/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:

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. "
5. Records Retention [Supplements Section D. (6.)]
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
122.41].
