Subject: FINAL -- NPDES Permit No. NCO031046
Colonial Pipeline Greensboro Terminal
Greensboro
Guilford County
Dear Mr. Leigh:
This letter transmits your Final NPDES individual discharge permit for the above referenced facility.
Please note corrected language from the draft regarding flow estimate methods [Permit A.(3.) through
A.(7.)]. Please review this draft carefully to ensure thorough understanding of the information, conditions,
and requirements contained therein for dischargers to water supply (WS) waters.
The Division of Water Quality (the Division) has reviewed your application to renew the subject
permit including your request to include discharge slab washdown and testing/calibration water at
additional outfalls. The Division has no objections provided that the revised effluent limits at each outfall
are not exceeded. As part of permit renewal, the Division has revised the Standard Operating Procedures
(SOP) for permitting this and all bulk storage petroleum facilities and terminals in North Carolina.
Permit renewal also included EPA -required Reasonable Potential Analysis (RPA) conducted on this
facility's effluent data to determine the "reasonable potential" for identified parameters to exceed state
and federal receiving -stream Water Quality Standards and criteria. This RPA has been applied
individually to each outfall (001 through 006). The following summarizes important changes to your
previous permit:
• Re -designated UT Pond (up -gradient of Outfall 006) as "waters of the State" [ISA NCAC
02B.0228 (1)].
• Re -designated Outfall 006 as a downstream sampling point "D"; Monthly monitoring, no limits.
• Added upstream sampling point "U", Monthly monitoring, no limits.
The Division offers the following explanations for these and other permit changes and requirements.
BTEX. The permittee is now required to monitor monthly for BTEX (benzene, toluene, ethyl
benzene and xylene) parameters. Please note that this replaces the requirement for EPA Method 624.
Benzene is limited because the RPA "maximum predicted" effluent level, based on submitted data,
exceeds the "allowable concentration" for WS waters of 1.19 µg/L. Effluents not showing "reasonable
potential" did not receive limits.

EPA Methods 624/625. Method 624 has been eliminated from facility monitoring because it did not
detect compounds other than BTEX. However, because the majority of facilities now store, or have
stored in the past, heavy -component fuels such as fuel oil and diesel, the Division has retained EPA
Method 625 monitoring to detect naphthalene and related indicators of middle distillate compounds
commonly found in these heavier fuels.
Phenol. The Division calculated a total stream wasteload allocation of 0.025 lbs./day at the
confluence of Long Branch and the East Fork of Deep River — the assumed beginning of High Point Lake
Water Supply. This allocation was distributed equally among nine (9) current oil -terminal dischargers
upstream; 0.003 pounds per day (lbs./day) per discharger. Using Colonial Pipeline's highest reported
flow for each outfall, the RPA predicted "reasonable potential" at all five outfalls. Therefore, the 0.003
lbs./day was further divided equally among each of five (5) Colonial Pipeline outfalls as a phenol limit of
0.0006 lbs./day. These calculations are available upon request. Colonial Pipeline is instructed to
continue to report phenol at the lowest possible practical quantitation level (PQL) available from
your North Carolina -certified laboratory.
MTBE is a gasoline component recently identified by the EPA as a potential human carcinogen.
Therefore, monthly monitoring has been added to this and all oil terminal permits discharging to WS
waters within the state. After collecting additional data, the permittee may request the Division to reduce
the MTBE monitoring frequency (See Permit Special Condition A. 7.). Granting this request shall
constitute a minor modification to the NPDES permit. It is anticipated that a Water Quality Standard or
criteria will be adopted for MTBE during this permit cycle, therefore a limit may be imposed at next
renewal.
Considering Outfall 006 and Waters of the State. Outfall 006 is located on the main stem of an
unnamed tributary (UT) to the East Fork of the Deep River. Outfall 006 monitors the effluent from
approximately 12-acres of ponded water (the UT pond) created by Colonial Pipeline straddling this
drainage. For several reasons this UT pond must be re -defined as "waters of the state," most importantly
because the Permittee does not control the entire discharge area to the pond as required for designated
"discharge channels" [15A NCAC 02B.0228 (1)). It is significant that the UT pond receives storm water
from offsite as well as effluent from several other NPDES permitted dischargers upstream.
While it is appropriate for Colonial Pipeline to use UT pond water for hydrostatic tank testing,
concrete slab washdown, or other stated uses, it is not appropriate to return this water to the UT pond
without first sampling and analyzing it for potentially introduced pollutants. Colonial Pipeline is
therefore instructed to confine to a permitted outfall, all tank -testing water and/or uptake water
such that it may be monitored prior to discharge to the UT pond, i.e. to "waters of the state."
It also follows, with discontinuing the return of uptake water, Outfall 006 becomes a downstream
and therefore "redundant" outfall to other UT pond discharges (Outfalls 001 through 005). Therefore,
location 006 is hereby re -designated a downstream sampling point, "D". Downstream sample point D is
to be monitored regularly and is unconfined by permit limits [See Permit A.(6), Instream Sampling and
Monitoring Requirements]. Furthermore, to protect Colonial Pipeline from potential unauthorized releases
upstream, the Division recommends that the Permittee also monitor upstream of the UT Pond [see A.(6.)].

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (7.) MTBE MONITORING
For the protection of public health, oil terminals discharging to waters classified as water supplies
("WS" waters) shall adhere to the following action plan:
1. Monthly monitoring for MTBE (except as modified under 2.) is required for the duration
of the permit [See Parts A. (L) through A. (6.)].
2. After a one-year Test Period of monthly monitoring or after twelve (12) discharge events
have been sampled and analyzed, the Permittee shall review MTBE data. If MTBE is not
detected, the facility may request the Division to reduce the MTBE monitoring
frequency. Granting this request shall constitute a minor modification to the NPDES
permit.
3. If MTBE is detected during the Test Period, the Permittee shall submit an MTBE
Reduction Plan. This plan may include site -specific Best Management Practices (BMPs)
or engineering solutions. A copy of this plan shall be submitted to:
North Carolina Division of Water Quality
Water Quality Section
Attn: NPDES Unit
1617 Mail Service Center
Raleigh, NC 27699-1617
4. The Division anticipates that an MTBE regulatory criterion or Water Quality Standard
will be established during the coming permit cycle. For the next cycle of permit renewals,
i.e., 2006, the Division expects to apply this criterion or standard to MTBE data collected
during this permit cycle. Should the Permittee's MTBE data indicate discharge in excess
of this criterion or Water Quality Standard, an MTBE limit will be added to the permit
monitoring requirements at renewal.

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (8.) ACUTE TOXICITY MONITORING (ANNUAL)
The Permittee shall conduct annual toxicity tests using protocols defined as definitive in EPA 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.
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 Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 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.

FACILITY RECORDS REVIEW
Facility Description. Colonial Pipeline (Table 1) operates the Colonial Pipeline Greensboro
Terminal, a petroleum pipeline -distribution and surface bulk -storage facility in Guilford County. This
facility is permitted to discharge through six (6) outfalls (Table 2). The Permittee controls surface
discharge utilizing a Water Pollution Control System consisting of settlement ponds, oil/water
separators, and discharge valves. Stormwater drains by gravity from a soil-remediation landfarm and
from diked containment areas (Outfalls 001 through 005). Discharge travels to a final settlement pond
also used to recycle testing/calibration water (Outfall 006). This pond is built within an unnamed
tributary (UT) and discharges indirectly to the East Fork of the Deep River (see 006 Discussion).

FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES Permit No. NCO031046
INTRODUCTION
Colonial Pipeline Company (herein referred to as Colonial Pipeline or the Permittee) requires a
National Pollutant Discharge Elimination System (NPDES) permit to dispose treated wastewater to
the surface waters of the state. The Permittee's 5-year NPDES permit has expired and they have
requested renewal from the Division of Water Quality (the Division). This Fact Sheet summarizes
background information and rationale used by the Division's NPDES Unit to determine permit limits
and conditions. This document also contains references to information sources relevant to this permit
renewal (superscripted numbers in order of appearance, See References).
FACILITY RECORDS REVIEW
Facility Description. Colonial Pipeline (Table 1) operates the Colonial Pipeline Greensboro
Terminal, a petroleum pipeline -distribution and surface bulk -storage facility in Guilford County. This
facility is permitted to discharge through six (6) outfalls (Table 2). The Permittee controls surface
discharge utilizing a Water Pollution Control System consisting of settlement ponds, oil/water
separators, and discharge valves. Stormwater drains by gravity from a soil-remediation landfarm and
from diked containment areas (Outfalls 001 through 005). Discharge travels to a final settlement pond
also used to recycle testing/calibration water (Outfall 006). This pond is built within an unnamed
tributary (UT) and discharges indirectly to the East Fork of the Deep River (see 006 Discussion).

This permit became effective July 1, 1996 (expiring date March 31, 2001). To stagger the renewal
workload, the Division extended the expiration date to August 31, 2001. t'Z On March 7, 2001, the
Division received the Permit Renewal Application and it was acknowledged the same day.

Outfall 006 Monitors "Waters of the State" — Discussion. Outfall 006 is located on the main
stem of an unnamed tributary (UT) to the East Fork of the Deep River. Outfall 006 monitors the
effluent from approximately 12-acres of ponded water (hereby designated the UT Pond) created by
Colonial Pipeline straddling this drainage (see Site Map). For several reasons this UT pond must be
re -defined as "waters of the state," most importantly because the Permittee does not control the
entire discharge area to the pond as required for "discharge channels" [12A NCAN 02B.0228 (1)].
For example, the UT pond receives storm water from offsite plus effluent from several other
permitted dischargers upstream. While it is appropriate for the Permittee to use UT pond water for
hydrostatic tank testing or other stated uses, it is not appropriate to return this water to the UT pond
without first sampling, analyzing, and reporting. In addition, Outfalls 001 through 005 discharge to
the UT pond (after sampling) making 006 a downstream or "redundant" sample to the others.
Location 006 should therefore be re -designated as a downstream sampling point — not an outfall, to be
monitored regularly (without permit limits). Considering the potential for unauthorized releases
upstream, the Division also judges it prudent to monitor upstream of the UT Pond.
In summary, this renewal shall reflect discharge monitoring through five (5) outfalls only, re -
designating one (006) as a downstream sample point, and shall also include upstream monitoring (see
permit Site Map for locations). Considering any future up -take from the UT pond water, the Division
recommends that the Permittee discharge up -gradient of a new or existing permitted outfall (other
than 006) so that this effluent may be properly monitored prior to re-entering "waters of the state."
Waste Load Allocation (WLA). The Division reviewed the WLA completed in May 1991 and
developed effluent limits and monitoring requirements.' The Division judges these limits and
monitoring requirements to be appropriate for this renewal with the exception of additions and
deletions listed below (see PERMITTING APPROACH SUMMARY).
Verifying Existing Stream Conditions. This facility discharges to an unnamed tributary (UT) of the
East Fork of the Deep River, a Class WS-IV stream within the Cape Fear River Basin. East Fork of
the Deep River is not listed as an "impaired" waterbody [not 303(d) listed].5
COMPLIANCE REVIEW
Discharge Monitoring Reports (DMR) -- Effluent Data Review. DMRs were reviewed from
January 1996 through July 2001.8 Discharges from Outfall 001 through 006 occurred episodically —
non -discharge months were reported as "no flow." For flow maximums and average number of
single -event discharges per month per outfall, see Table 3. Based on the Division's review of the
DMRs, EPA 624/625 scans did not detect semi -volatile or volatile organic compounds other than
benzene, toluene, ethyl benzene, and xylene (BTEX). For further discussion, see Permitting Strategy.
Total suspended residue (TSR) levels (to 120 mg/L) occasionally exceeded recommended levels (40

Total suspended residue (TSR) levels (to 120 mg/L) occasionally exceeded recommended levels (40
mg/L) at Outfall 006. Reported maximum flows were used to establish "reasonable potential" for
each outfall (see RPA calculations).

Facility Inspections. The Winston-Salem Regional Office (WSRO) last inspected this facility on
February 21, 1996. Due to staff shortages and regional priorities, this Class I Stormwater Treatment
System has been assigned lower priority relative to other discharge systems, however starting .this
permit cycle, the WSRO has scheduled regular annual inspections for this and all bulk -petroleum
storage facilities in the Greensboro area.10
Whole Effluent Toxicity (WET) Test. The facility has passed its annual acute toxicity test at all
outfalls (001 through 006) for the past six (6) years (1996 through 2001).
PERMITTING STRATEGY
Revised Standard Operating Procedures (SOP). The Division of Water Quality has revised
permitting strategies and SOP for this and all oil terminals in the state.6 A new document has been
generated by the NPDES Unit entitled, "Standard Operating Procedures -- Permit Requirements for
Discharges from Oil and Petroleum Storage Facilities" (based on a 1996 SOP). This document,
hereafter referred to as the 2001 SOP, addresses issues and delineates monitoring frequencies and
permit limits for contaminants commonly found at these facilities.
Summary of Compliance Under 2001 SOP. Under the 2001 SOP, flow monitoring shall be
changed from "monthly" to "episodic" (Parts L.A. ). This facility's effluent data shall be evaluated for
compliance with acute toxicity, TSS, and oil and grease (Parts L.B. through LD.). In place of EPA
Methods 624/625 monitoring requirements, and/or eight (8) chlorophenols specified in a previous
permit, the Permittee shall now monitor monthly for total phenolic compounds only (Phenols -- Part
LE.), as required for all WS (water supply) waters. Monthly monitoring shall include benzene,
toluene, ethyl benzene, and xylene (BTEX -- Part !!/.A.). The Division shall also require monthly
monitoring for MTBE (2001 SOP Part LL) considering WS waters.6
Footnotes to the Effluent Limits and Monitoring Requirements page shall reflect no direct discharge
of tanks solids, tank bottom water, or the tank rag layer. Footnotes also stipulate no direct discharge

of hydrostatic test water if benzene and/or toluene concentrations exceed their respective water
quality standard (2001 SOP, Parts LG. and LH).
Phenol — Monitoring and Limits Calculations. When combined with chlorine, phenol can cause
taste and odor (organoleptic) problems in drinking water, and can also result in the tainting of fish
tissues. Therefore, in accordance with SOP 2001, all dischargers to state water supply (WS) waters
shall conduct monthly effluent monitoring for total phenol. Moreover, if analytical results suggest
"reasonable potential," a phenol limit shall be included in the permit.6
A phenol limit magnitude depends on dilution. Ideally dilution would be calculated at the High Point
Dam water plant intake where chlorine is introduced, but it is impractical at this time to measure
dilution under lake conditions at the intake. Therefore, the Division calculated flow at the assumed
headwaters of this water supply. Secondly, the Division used 1 µg/L (the aesthetic limit for phenol) to
calculate a wasteload allocation in pounds per day (Ibs./day) at these headwaters. Finally, the
wasteload allocation was distributed equally among phenol dischargers as a permit limit, only as each
facility's data -set showed reasonable potential to exceed the water quality stream standard.
Currently nine (9) bulk storage facilities discharge to either the East Fork Deep River or Long
Branch. The confluence of these two drainages was assumed to approximate the headwaters of High
Point Lake, the nearest downstream intake waterbody. For purposes of yield calculations, Long
Branch was assumed to have a similar runoff coefficient as the East Fork of the Deep River. The
Division used published 30Q2 flows from an EPA stream gauge (02099000) located on the East Fork
Deep River near the confluence of the two drainages. The 30Q2 flow, not the 7Q10, was deemed
appropriate because of the aesthetic standard for phenol.
Flow Calculations:
Given: Flow (30Q2) East Fork Deep River = 3.8 cfs (USGS Gauging Station)
Drainage Area East Fork Deep River = 14.8 mix (USGS)
Drainage Area Long Branch = 3.84 mil (measured from USGS topo)
Total Drainage Area = 14.8 mix + 3.84 mix
18.6 mix
Yield = East Fork Flow (cfs)
East Fork Drainage Area (mil)
= 3.8 cfs
14.8 mil
0.257 cfs/mix
Therefore:
Total Flow = Yield x Total Drainage Area
0.257 cfs/mix x 18.6 mix
4.7 cfs
Wasteland Calculation:
4.7 cfs x 0.001 mg/L x 8.34 = 0.025 Ibs./day distributed among nine

RPA on Colonial Pipeline's reported data for six outfalls. The RPA compares the "allowable
concentration" (based on water quality standard or criteria) the "maximum predicted" concentration
based on data submitted (1996 through June 2001). RPA results for phenols and benzene, toluene,
ethyl benzene, and xylene (BTEX), and oil & grease parameters are summarized per outfall in Tables

Re: Colonial Pipeline Company - Renewal Application
NPDES Permit NCO031046
Greensboro Terminal
Guilford County
Mr. Weaver:
Telephone: [phone]
Facsimile. 336-292-6462
Colonial Pipeline Company requests renewal of the above referenced NPDES permit. Please find enclosed one original and two (2)
copies of the renewal application.
We have a total of silt (6) outfalls at this facility. We request that five (#'s 001, 002, 003, 004, & 005) of the six be permitted for
storm water runoff, wash down slab water, and prover -loop calibration water. Although wash down slab water and prover -loop
calibration water rarely involve enough volume to generate a discharge, we would like to have this potential source included in our
permit. We also request that outfall #006 continue to be permitted for hydrostatic test 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 each application.
Although I am not an officer of the company, I am the Operate in Responsible Charge (ORC) and the authorized agent (see attached)
for this facility. If this renewal application requires additional signatures, please let me know. If you have questions or require
additional information, please contact me at [phone] or at the letterhead address. 'Thank you for your assistance with this
renewal.
Sincerely,
Faron D. Leigh (J
