Subject: Final NPDES Permit NCO081469
RDU Delivery Facility
Class I - Physical -Chemical WPCS
Wake County
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached final NPDES discharge permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated October
15, 2007 (or as subsequently amended).
The final permit has a few changes in language from the draft permit that was previously sent
to you dated July 11, 2023. Changes to the final permit are in response to comments received
from Resolve Environmental on behalf of Colonial Pipeline Company dated August 9, 2023.
The Division's response to these comments is outlined below. The cover letter for your draft
permit summarized other changes in your permit from the previous permit, please refer to that
description for additional information.
Resolve Environmental submitted comments on the draft permit on behalf of Colonial Pipeline
(August 9, 2023 letter). The Division reviewed these comments and provided responses through an
email on August 16, 2023. These are highlighted here:
• Colonial questioned the inclusion of a limit in the permit for total recoverable phenolics and
noted a data point that was inaccurately reported. In subsequent correspondence with
Resolve and Colonial staff it was found that five (5) data points were inaccurately reported
over the permit cycle. The correct data was provided and DWR staff re -ran the RPA analysis
and found that no reasonable potential exists for total recoverable phenolics. Monitoring will
be maintained in the permit, but the proposed limit has been removed. References to Total

Recoverable Phenolics in the Compliance Schedule in Section A.(5.) have been removed.
Please ensure that all monitoring data is reported accurately in the eDMR system for future
submittals. Total recoverable phenolics should be reported in µg/L.
• Your comments noted a discrepancy in the reporting frequency for Method 625.1 parameters.
The final permit has been corrected so that the monitoring frequency for these parameters in
the effluent table and in Section A.(4.) each reference semi-annual (2/year) monitoring.
• Your comments raised issues associated with the inclusion of limits for toluene and
naphthalene in the permit. You requested a copy of the RPA analysis and noted that the
discharge outfall included stormwater runoff from offsite that could impact the discharge. A
copy of the RPA results was provided with the August 16th email and the email outlined the
RPA process in accordance with 40 CFR 122.44 (d) (i). The Division understands Colonial's
concerns with potential offsite contributions, but we are required to address discharges in a
manner that assures proper limitations are established where discharge of a pollutant has
reasonable potential to impact water quality standards. Colonial has been given a five-year
compliance schedule as you have mentioned in your comments. Colonial may choose to
review alternatives that could remove offsite contributions from your discharge during this
compliance window, but as long as these levels of pollutants are a part of your discharge the
Division is obligated to include these limitations in the permit.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this letter. This request must be in the form of a written
petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-
6714). Unless such demand is made, this permit shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the
legal requirements to obtain any other Federal, State, or Local governmental permit that may be
required.
If you have any questions or need additional information, please do not hesitate to contact Bradley
Bennett of my staff at [phone] or [e-mail].

1. The Permittee shall submit Monthly Discharge Monitoring Reports (DMRs) electronically utilizing the
Division's Electronic Discharge Monitoring Reporting (eDMR) System [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 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.

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.

Permit NCO081469
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-VOCs). The permittee shall conduct Semi -
Annual 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.

DocuSign Envelope ID: C74FDE7F-1F79-435A-AE3A-38DOCF4D74AB
Permit NCO081469
(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:

limits for Toluene and Naphthalene will not be imposed. During this time the permittee will undertake
reviews and actions to move toward compliance with these limits in the next permit cycle. Actions
taken by the permittee and data collected during this permit cycle may result in evaluations that adjust
the required limits for the parameters of concern in future permits.
(a.) No later than one year from the effective date of this permit the permittee shall submit a report
summarizing the actions taken toward compliance with the permit limits.
(b.) No later than two years from the effective date of this permit the permittee shall submit a report
summarizing the actions taken toward compliance with the permit limits.
(c.) No later than three years from the effective date of this permit the permittee shall submit a
report summarizing the actions taken toward compliance with the permit limits.
(d.) No later than four years from the effective date of this permit the permittee shall submit a
report summarizing the actions taken toward compliance with the permit limits. This report
may be combined with the permittee's submittal of the renewal application for this permit and
should include information that the Division should consider in evaluating limits for Toluene
and Naphthalene in the renewal process.
The reports shall include the owner's name, NPDES permit number and Permittee contact person, and
shall be submitted to:

Permit NCO081469
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://deg.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.
Page 11 of 14

DocuSign Envelope ID: C74FDE7F-1F79-435A-AE3A-38DOCF4D74AB
Permit NCO081469
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.federalre isg ter.g_ov/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

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which is
not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or

(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWR or "the Division"
The Division of Water Resources, Department of Environmental Quality.
Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC
The North Carolina Environmental Management Commission
EPA
The United States Environmental Protection Agency
Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).

Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA.
Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
Monthly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform or other bacterial parameters or indicators, the geometric mean of such discharges.

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [I 5A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40
