4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: 1) to verify model predictions
when model results for instream DO are within 1 mg/1 of instream standard at full permitted flow; 2) to
verify model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other
instream concerns. Instream monitoring may be conducted by the Permittee, and there are also
Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee (in
which case instream monitoring is waived in the permit as long as coalition membership is maintained).
If applicable, summarize any instream data and what instream monitoring will be proposed for this
permit action: No changes are proposed.

6. Water Quality -Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
In accordance with 15A NCAC 2B.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1Q10 streamflow (acute Aquatic Life); 7Q10 streamflow (chronic Aquatic
Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): Not
modeled.
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B. 0204(b): NA.
Oxygen -Consuming Waste Limitations
Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD= 30 mg/1 for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: NA.
Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/1 (summer) and 1.8 mg/1 (winter). Acute ammonia limits are derived from chronic criteria,
utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non -Municipals.
Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 ug/1) and capped at 28 ug/1(acute impacts). Due to analytical issues, all TRC values
reported below 50 ug/1 are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: NA.
Reasonable Potential Analysis (RPA) for Toxicants
If applicable, conduct RPA analysis and complete information below.
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC
RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero
background; 3) use of Y2 detection limit for "less than" values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between Jun2016 and
Nov2021. Pollutants of concern included toxicants with positive detections and associated water quality
standards/criteria. Based on this analysis, the following permitting actions are proposed for this permit:
Page 6 of 13

• Effluent Limit with Monitoring. The following parameters will receive a water quality -based
effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable
water quality standards/criteria: Outfall 004 MTBE.
• Monitoring Only. The following parameters will receive a monitor -only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria:
Total Recoverable Phenolics, Benzene, Naphthalene, Toluene, Ethyl Benzene, Xylene, and
MTBE (except Outfall 004).
• Summary of new limits added based on RPA: None

this Fact Sheet. Include a printout of the RPA Dissolved to Total Metal Calculator sheet if this is a
Municipality with a Pretreatment Program.
Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in
accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging "complex" wastewater (contains anything other than
domestic waste) will contain appropriate WET limits and monitoring requirements, with several
exceptions. The State has received prior EPA approval to use an Alternative WET Test Procedure in
NPDES permits, using single concentration screening tests, with multiple dilution follow-up upon a test
failure.
Describe proposed toxicity test requirement: If Acute WET -test fails [TGE6C], the Permittee shall test
each subsequent discharge event until testing indicates "pass," after which Quarterly monitoring shall
resume in accord with Section A. (9.). If after a subsequent five (5) consecutive Quarterly events, WET
results demonstrate no toxicity (i.e., "pass"), the Permittee may petition the Division to relax monitoring,
as data may warrant.
Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply with
EPA's mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources (-2% of total load), the TMDL emphasizes mercury minimization plans (MI IPs) for point source
control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (>1 ng/1) will
Page 7 of 13

receive an MMP requirement. Industrials are evaluated on a case -by -case basis, depending if mercury is a
pollutant of concern. Effluent limits may also be added if annual average effluent concentrations exceed
the WQBEL value (based on the NC WQS of 12 ng/1) and/or if any individual value exceeds a TBEL
value of 47 ng/1
Describe proposed permit actions based on mercury evaluation: NA.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: NA.
Other WQBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: NA.
If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbody: NA.
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with
15A NCAC 2H.0107(c) (2) (B), 40CFR 122.47, and EPA May 2007 Memo: NA.
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B. 0226 for this permit renewal: NA.
7. Technology -Based Effluent Limitations (TBELs)
Secondary treatment requirements for TSS (30 mg/1 Monthly Average and 45 mg/1 for Daily Maximum
Limit).
8. Antidegradation Review (New/Expanding Discharge):
The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation
review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit
must document an effort to consider non -discharge alternatives per 15A NCAC 2H.0105( c)(2). In all
cases, existing instream water uses and the level of water quality necessary to protect the existing use is
maintained and protected.
If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: NA.
Page 8 of 13

9. Antibacksliding Review:
Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(1) prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit (YES/NO): Yes.
If YES, confirm that antibacksliding provisions are not violated: Based on updated RPA. See RPA for
detail. Turbidity limits were removed from the effluent because the water quality standard is a narrative
standard based on instream conditions.
10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following
regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2)
NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance,
Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best
Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not
considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti -
backsliding prohibitions would not be triggered by reductions in monitoring frequencies.
For instream monitoring, refer to Section 4.
11. Electronic Reporting Requirements
The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective
December 21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports
(DMRs) electronically. Effective December 21, 2020, NPDES regulated facilities will be required to
submit additional NPDES reports electronically. This permit contains the requirements for electronic
reporting, consistent with Federal requirements.

NCDEQIDWRINPDES
Colonial Pipeline Company requests renewal of the above referenced NPDES permit. Please find enclosed one (1) original and two
(2) copies of the renewal application.
We have a total of five (5) outfalls at this facility that mainly treat storm water through oil/water separators and/or retention ponds and
basins. Other than storm water, we sporadically generate wastewater from equipment wash down slabs, hydrostatic test water, and
prover -loop calibration water. Our operation does not generate sludge and/or solids and, therefore, we do not have a sludge
management plan. I have included a copy of our watershed runoff— effluent flow with this application.
Thank you very much for your assistance with this permit renewal. If you have questions or require additional information, please
contact me at [phone] or at the letterhead address.
Sincerely,
X4Z

Dear Mr. Denard:
RE: Request for Additional Information
NPDES Renewal Application
Permit NC0031046
Colonial Pipeline Company (CPC) received your request for additional information on the recently
submitted National Pollution Discharge Elimination System (NPDES) Permit renewal dated August 10,
2021.
Attached please find the requested EPA NPDES Permitting Forms 1 and 2E. This facility has five outfalls
(001 through 005) and also is required to collect an upstream sample and a downstream sample. In
September 2021, we added BOD5 and Ammonia (as N) to our monthly sampling requirements in order
to complete Form 2, Section 4.2 for each outfall. In September 2021, we were unable to collect a
sample from Outfalls 003 and 005 due to lack of flow at the outfalls. Therefore, we do not have BOD5
and Ammonia (as N) results for these two outfalls. Should we get a flow from Outfalls 003 and 005 in
October, we will have the surface water samples analyzed for these additional parameters. We are also
lacking temperature and pH for the sampling locations. These field parameters will be noted during the
monthly October 2021 sampling event. We will submit a revised Form 2E once these analytical results
and field parameters are obtained.
If you or a representative from your department would like to inspect this tank during the degassing
operation or if you should have any questions, please contact me at 704-458-3993 or John Wyatt,
Southeast District Associated Environmental Manager, at 423-713-9270.

RECEIVED
1 9 2021
NCDEQ/DWR/NPDtS
Colonial Pipeline Company (CPC) received your request for additional information on the recently submitted
National Pollution Discharge Elimination System (NPDES) Permit renewal dated August 10, 2021. We
responded on October 8, 2021 with a new permit application package which included EPA NPDES Permitting
Forms 1 and 2E. For the October 8, 2021 package, we had not received the BOD5 and Ammonia (as N)
results for Outfalls 003 and 005. This revised submittal includes these results.
Can you please inform me of the permit renewal application review process and the estimated timeline?
Please contact me at 704-458-3993 or John Wyatt, Southeast District Associated Environmental Manager,
at 423-713-9270 should you have any questions concerning this permit renewal application.
Sincerely,

SUBJECT: Compliance Evaluation Inspection
Colonial Pipeline Company — Greensboro Junction, PC-1
NPDES Permit No. NC0031046
Guilford County
Dear Mr. Pruitt:
On August 8, 2018, Jenny Graznak, of this office, met with Faron Leigh to perform
a Compliance Evaluation Inspection on the Colonial Pipeline Company — Greensboro
Junction, PC-1 stormwater/wastewater treatment system. This type of inspection
consists of two basic parts: an in -office file review and an on -site inspection of the
treatment facility. The attached EPA inspection form notes the areas that were evaluated
for this inspection. The findings and observations are outlined below:
I. Permit
The NPDES permit became effective January 1, 2017 and expires August 31,
2021. The facility had a copy of the current permit available during the inspection. The
treatment structures seen during the inspection match those listed in the permit.
II. Self -Monitoring Program
A review of the monthly discharge monitoring reports (DMRs) for the period July
2017 through June 2018 showed that the facility complied with all permit limits. Regarding
the permit monitoring requirements, it was noted that all sampling was performed per the
frequencies specified in the permit. All laboratory analysis is performed by Pace Analytical
Services, LLC. Mr. Leigh collects all the monthly and/or quarterly grab samples from the
five different outfalls, and then a representative from Pace Analytical picks them up from
the site.
One issue with the self -monitoring program was noted on the day of the inspection.
Mr. Leigh is currently collecting the upstream sample from the upstream section of the
upper retention pond. However, Ms. Graznak pointed out that he needs to collect the

upstream sample from a location that is a minimum of 75 feet upstream of the influent
pipe to the settling pond, as stated in the current permit in Part I, Section A. (6).
III. Records/Reports
Mr. Leigh maintains a visitation log that also documents flow estimates. Chain of
custody forms and lab data sheets are in good order. All the required monitoring was
performed per the frequencies specified in the NPDES permit. Ms. Graznak noted no data
transcription discrepancies from lab sheets to DMRs in her documentation review.
IV. Flow Measurement
The permit requires episodic flow monitoring for each ouffall. No meter is used for
flow measurement. Instead, the discharge volume is computed using the Rational
Method, as outlined in the current permit.
V. Operations and Maintenance
Colonial Pipeline staff perform a daily walk to inspect the ponds and the discharge
outfalls. The oil/water separator is cleaned out on an as -needed basis by Zebra
Environmental. The wash water from cleaning the aboveground storage tanks is sent off
site for disposal.
VI. Facility Site Review
The dikes around the tank farm have hand -operated control valves that are
normally closed. The tank farm has five outfalls (001 thru 005) that drain to the same on -
site pond. The only issues observed at these outfalls are as follows:
- Outfall 002: Ms. Graznak observed approximately 20 very small dead fish (all same
species) at Outfall 002. However, she also observed a larger number of live,
swimming fish in the same location. Please pay particular attention to this ouffall
in the coming weeks to determine if that was a one-time incident or not.
Outfall 004: The retention pond at Outfall 004 showed signs of erosion on its
streambanks and should be repaired.
VII. Effluent/Receiving Waters
All five outfalls were discharging, and the effluent was clear on the day of the
inspection. Effluent was being discharged into an unnamed tributary to the East Fork
Deep River, class Water Supply -IV* waters, in the Cape Fear River Basin. Ms. Graznak
did not observe solids, color, or odor associated with the effluent.

VIII. Requested Action
- Please correct the upstream sample location as described in this letter.
- Please pay close attention to Ouffall 002 and let our office know if any more dead
fish are observed.
- Please make efforts to repair the streambank erosion at the Outfall 004 pond.
Colonial Pipeline Company's efforts to comply with the permit are appreciated. If
you have any questions regarding the inspection or this report, please contact Ms.
Graznak or me at [phone].

Ben,
Yes, "Commission" was omitted from the line below the signature. Thanks for catching that for me.
The acute fathead minnow WET test is assigned in accordance with the attached permitting strategy.
Also attached is the boiler plate permit condition freshwater acute limit PF fathead minnow TGE6C. I
believe they don't have an option of using Ceriodaphnia dubia in this condition that was approved by the
aquatic tox branch and the water quality permit section.
Additionally, WET strategy was worked out in 1999 (see attached memo Coleen Sulllins, August 2,
1999). From what I gather, since this facility is an episodic stormwater discharge under zero flow
conditions (7Q10/30Q2 = 0, IWC = 100%), acute fathead minnow was the organism selected.
If is my best effort in a few minutes at putting the WET test history together for bulk storage terminals.
Thanks,

Derek,
I attached the signed memo.
Note on Permit Page 1 of 13, below the signature line should read "By Authority of the Environmental
Management Commission."
I was also wondering about Part I, A.(9.) — Acute Toxicity. It requires that the fathead minnow be used in acute
toxicity testing. Is there a reason the permittee isn't presented the option of using other acceptable species (e.g.,
Ceriodaphnia dubia)?

Unless something has changed, I am just going to follow the strategy I have in hand. The 2005 strategy.
See attached. These are on the back -log. I going to expediate them as best I can. Seems like this issue
comes up every time. I am not sure what the answer is. I updated the Tox condition and have kept the
footnote language the same as what I have done for the Paw Creek, just we just did for Greensboro, and
what I am about the to do for the Wilmington terminals. We spent a lot of time on this issue in the past
and I thought we had worked it out. I recall when someone else was working on the Selma terminals
there was push back from the permittee when we were thinking it should be all quarterly. We can take it
up with John again if it helps. I can set something up us.

Thanks for copying me. We can do that if needed. My first thought however is we may need to send
these drafts to the tox group earlier. Did we start sending the draft permits to the regions when they
go for peer review. Maybe we need to send it to AT at the same time if we aren't already.

Hi Derek,
Everything for Tox looks good.
Just to confirm, they are annual testing Fthd24PF @ 90%, if fail — they sample monthly until a pass result, then
switch to quarterly for 5 quarters. After 5 passing quarters, they can request to go back to annual testing?
Cindy and I debated about the annual part of the language and there really isn't anything about it in the
"subsections" (A9 in this case). It only states annual in the table and briefly in the footnote. We have been
working with Kent Wiggins on some of the other toxicity language for the permits and we (Cindy and I) are
curious if the permittees may benefit from having an additional section that pertains to just the annual testing
requirements so it will stand out more clearly?
Thank you,
Zach Thomas

Michael,
I don't believe this changed from the previous permit. Outfalls 001 through 005 have been given annual
monitoring conditionally as it is stated in Footnote 4:
If Acute WET -test fails [TGE6C], the Permittee shall test each subsequent discharge event until
testing indicates "pass," after which Quarterly monitoring shall resume in accord with Section A.
(9.). If after a subsequent five (5) consecutive Quarterly events, WET results demonstrate no toxicity
(i.e., "pass"), the Permittee may petition the Division to relax monitoring, as data may warrant.
Section A. (9.) is written as quarterly with the required months.
If you have questions, let me know.

We are in receipt of the new NPDES permit for the Colonial Pipeline Greensboro Junction site (No. NC0031046)
and need some clarification regarding Acute Toxicity testing. The permit indicates that the Acute WET Testing is
required for Outfalls 001 through 005 on an annual basis (Pages 3 through 7). However, Page 10 of the permit
indicates that the Acute WET Testing is required quarterly.
We believe this testing should only be required annually, however, please clarify.
Thank you -
