Subject: Issuance of NPDES Permit NCO031046
Colonial Pipeline Company
Guilford County
Dear Mr. Leigh:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached 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 May 9, 1994 (or as
subsequently amended).
This final permit includes no significant changes from the draft permit sent to you on October 25, 2006.
However, there are terms within this permit that are different from the one that is currently effective.
These changes are primarily with regard to removal of limitations and reductions in monitoring
frequencies for various parameters at each of the outfalls. These changes were made based upon a
reasonable potential analysis of effluent data submitted by the facility, and were detailed in the October
25, 2006 cover letter accompanying the draft permit. One change not noted in that letter (but shown in
the permit's terms) was that the limit for Xylene has been removed for outfalls 003, 004 and 005. A
typographical error was corrected within footnote 4 following the monitoring requirements to refer you
to Section A. (8) of the permit for details on the toxicity testing requirement.
Because of the number of changes made to the permit, you are encouraged to read the permit carefully
and familiarize yourself with its terms in order to help ensure compliance with its conditions. Specific
attention should be given to Section A. (7.), a new requirement calling for Colonial Pipeline to prepare
and submit a plan detailing steps it will take to reduce or eliminate concentrations of MTBE in its
discharge. Additionally, the facility is directed by this condition to implement the plan after it has been
developed.
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 decision shall be final and binding.

Footnotes for All Outfalls
1. Flow — Flow shall be monitored with each discharge event — During periods of no flow,
the Permittee shall submit a signed, monthly Discharge Monitoring Report (DMR)
indicating "No discharge." Flow may be monitored using any one of four methods:
a) measure flow continuously;
b) calculate flow (see Rational Equation below) based on total rainfall per unit area
draining to the outfall; exclude built -upon areas (best method for facilities with
large runoff -collection ponds);
c) estimate flow at 20-minute intervals during the entire discharge event; or
d) report flow based on discharge pump logs."
The Rational Equation: Q=KuCIA, where:
Q = flow (peak flow rate (cfs or m3/sec)
Ku = units conversation factor = 1.008 for U.S. standard units (usually ignored because
it is so close to 1), or 0.278 for SI 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 the beginning of rainfall excess when all portions
of the drainage basin are contributing simultaneously to flow at the outlet).
A = area of tributary watershed (acres or km2)

Permit NCO031046
The rational equation is used to calculate the runoff from a region, given:
• the runoff coefficient which accounts for infiltration and other potential
losses in the region,
• the rainfall intensity to the region,
• the time it takes for runoff to travel from the region's upper reaches to its
outlet, and
• the region's drainage area.
2. Oil and Grease — Where possible, the grab sample for oil and grease should be skimmed from
the surface of a quiescent (calm water) zone.
3. MTBE— See Condition A. (7) for additional details.
4. Acute Toxicity (Fathead Minnow, 24-hour), Annual [see Special Condition A. (8.)].
The Permittee shall collect Acute Toxicity samples concurrently with BTEX sampling.
There shall be no discharge of floating solids or foam visible in other than trace amounts.
There shall be no direct discharge of tank solids, tank bottom water, or the rag layer.
There shall be no direct discharge of tank (or pipe) contents following hydrostatic testing unless benzene
concentration is less than 1.19 µg/l and toluene concentration is less than 11 µg/l.
A. (6.) INSTREAM SAMPLING AND MONITORING REQUIREMENTS
Beginning on the effective date of the permit and lasting until expiration, the Permittee shall collect
instream samples and provide analyses as needed to evaluate the existing Water Pollution Prevention
System. Such instream sampling shall be limited and monitored by the Permittee, as specified below.

Permit NCO031046
A. (7.) MTBE SPECIAL CONDITION
Methyl Tertiary Butyl Ether (MTBE) has been identified by the EPA as a potential human
carcinogen. Although North Carolina has not established water quality standards for this
compound, the state has concern about the discharge of treated wastewater with even small
concentrations of MTBE, especially when the discharge is to water supply (WS) waters. Because
MTBE has shown to be present in discharge from the outfalls permitted by NC0031046,
monitoring for this parameter shall continue pursuant to the terms established in sections A (1)
through A (6). Additionally, the permittee is required to submit a MTBE Reduction Plan within
six months of the effective date of this permit. 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
Surface Water Protection Section
Attn: NPDES Unit
1617 Mail Service Center
Raleigh, NC 27699-1617
The plan should be implemented without delay. The Division will review the plan and the results of
monitoring to determine whether additional measures must be taken to deal with the discharge of
MTBE.

Permit NCO031046
A. (8.) ACUTE TOXICITY MONITORING (ANNUAL)
The permittee shall conduct annual 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 toxicity test must be performed by June 30. Should there be no discharge of flow from the
facility during the six month period January 1-June 30, 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 in the comments section indicate "No Flow for January 1-June 30, (calendar
year)." The report must be signed and submitted to the Environmental Sciences Section at the address
noted below.
If no discharge event occurs from January 1-June 30, vet a discharge event occurs from July 1-December
31, then the facility must perform toxicity monitoring and report the data as noted 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 Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.
Should any test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water 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.

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.
Facility Description
Colonial Pipeline operates the Colonial Pipeline Greensboro Terminal, a petroleum pipeline -
distribution and surface bulk -storage facility in Guilford County. This facility is permitted to
discharge stormwater runoff, slab wash -down water, Prover-loopTM (or similar) calibration
water, and hydrostatic tank -testing water through Outfalls 001 through 005 from the existing
Water -Pollution Control System consisting of gravity -drained diked secondary -containment
structures and soil remediation landfarm; a system utilizing ponds, oil/water separators, and
discharge control valves; servicing manmade confinements identified as:

Each of the permitted outfalls discharge into a(n approximately) 12 acre pond located on the
Colonial Pipeline property that has been created by an impoundment of an unnamed tributary
to the East Fork of the Deep River. In some previous permit cycles, discharge from the pond
was referred to as Outfall 006. However, with the last permit reissuance, the pond was re-
defined as "waters of the state," mainly because the Permittee does not control the entire
discharge area to the pond as required for "discharge channels" [12A NCAN 02B.0228(1)].
The UT, and therefore, the pond receives storm water from offsite plus effluent from several
other permitted dischargers upstream. While it is appropriate for the Permittee to use pond
water for hydrostatic tank testing or other stated uses, it is not appropriate to return this water
to the pond without first sampling, analyzing, and reporting. The pond's outfall has been
designated as a downstream sampling point, and is 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 pond.
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. The East Fork of the Deep River is
listed as an impaired waterbody on North Carolina's 303(d) list. This reach of the river has
been placed on the list due to exceedence of water quality standards being observed for
Turbidity and Fecal Coliform, and the observation of impaired biological integrity in the
stream. The 2006 draft 303d list lists "MS4 NPDES" as the potential source for the
impairment. The 2004 list showed "Urban Runoff/Storm Sewers" and "Industrial Permitted"
as potential sources.

Compliance Review
Discharge Monitoring Reports (DMR) -- Effluent Data Review.
DMRs were reviewed from January 2002 through November 2005 (in some cases through
March 2006). Discharges from Outfall 001 through 005 occurred episodically — non -
discharge months were reported as "no flow." EPA 625 scans detected volatile organic
compounds other than benzene, toluene, ethyl benzene, and xylene (BTEX) on only one
occasion (Di-N-Octyl-phthalate detected at 14 ug/I from outfall 003 in March 2006).
Benzene and Toluene exceeded permit limits for outfalls 003 and 004 on a number of
occasions. Total suspended solids (TSS) levels occasionally exceeded permit limits at all
outfalls.
Notices of Violation (NOVs).
The facility was issued NOVs for single event violations of the TSS limit for outfall 002 that
occurred during August 2003 and November 2005. It has also been assessed civil penalties
on 11 different occasions during the past permit cycle (another penalty case was withdrawn).
BIMS shows one case (LV-2002-0226) is still unpaid and open. Most penalties were
assessed for violations of TSS, benzene and toluene limits.
Facility Inspections
The Winston-Salem Regional Office (WSRO) last inspected this facility on October 20,
2005. On that date and on two previous inspections during the permit cycle, the facility was
found to be in compliance with the terms of the NPDES permit.
Whole Effluent Toxicity (WET) Test
The facility has passed its annual acute toxicity test at all outfalls for the past eleven years
(1996 through 2006).
Permitting Strategy
The permit was developed using a strategy and guidance found in a Point Source Branch
document entitled "NPDES Permitting Requirements for Petroleum Bulk Storage: Surface
Storage Greater than One Million Gallons — 2005 Permitting Strategy." This document is an
update to the 2001 SOP for petroleum bulk storage facilities that guided development of the
current permit. The document provides guidance specifically targeted toward the
circumstances surrounding stormwater and other types of discharges common to petroleum
storage facilities.
As part of the permitting process, a Reasonable Potential Analysis (RPA) was run at each
outfall for those parameters that had a limit or standard established and showed some
detection for the parameter during the period of review. If a parameter was reported as the
test method's minimum detection level for all sampling events, the RPA was not run, but
decisions regarding limits and monitoring frequencies were made based upon that record of
performance.

Phenol — Monitoring and Limits Calculations
When combined with chlorine, phenol can cause taste and odor problems in drinking water,
and can also result in the tainting of fish tissues. Therefore, in accordance with 2005
Permitting Strategy, all dischargers to state water supply (WS) waters shall conduct monthly
effluent monitoring for phenol. Moreover, if analytical results suggest "reasonable potential,"
a phenol limit shall be included in the permit.
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
I µg/L (the aesthetic limit for phenol) to calculate a wasteload allocation in pounds per day'
(lbs./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 mil (USGS)
Drainage Area Long Branch = 3.84 mil (measured from USGS topo)
Total Drainage Area = 14.8 mil + 3.84 miZ
= 18.6 miZ
Yield = East Fork Flow (cfs)
East Fork Drainage Area (miZ)
= 3.8 cfs
14.8 miZ
0.257 cfs/miZ
Therefore:
Total Flow = Yield x Total Drainage Area
0.257 cfs/miZ x 18.6 miZ
4.7 cfs

The allocation is then distributed equally among all outfalls to determine "reasonable potential" for
phenol. With 5 outfalls, the allocation per outfall becomes 0.0006 Ibs/day.

Maximum Reported Flow (MGD)
In this example, a maximum allowable concentration (based upon the allocation and the highest flow
reported during the period of review) was determined (0.07 µg/L) and included as an input in the
analysis in order to determine whether there is "reasonable potential" that the discharge from Outfall
001 may cause the water quality standard for phenol to be exceeded. Similarly for the remaining
outfalls, the Division calculated corresponding phenol levels (based on maximum flow) as a
"standard" against which to determine "reasonable potential." These numbers are:
002:
1.42 ug/L
003
0.95 ug/L
004
0.08 ug/L
005

Reasonable Potential Analysis (RPA)
The Division conducted the EPA -mandated RPA on Colonial Pipeline's reported data for four of its
five outfalls (where discreet values were reported). The RPA compares the "allowable concentration"
(based on water quality standard or criteria) against the "maximum predicted" concentration based on
data submitted (January 2002 through March 2006). Significant results of the RPA, and the decisions
those results led to, are summarized below.
Outfall 061
Oil & Grease 2005 strategy does not call for inclusion of limit. Additionally,
reasonable potential not found. Removed limit. Decreased monitoring
from Monthly to Quarterly due to consistent performance, reporting
less than detect for all months except July 2002 (5.3 mg/L).

Phenol All values except one (December 2002) were reported as less than
detect. RPA did show reasonable potential (program would show
reasonable potential if no phenol was detected), but outfall shows
long-term good performance for the parameter. Removed limit;
retained monthly monitoring, in line with the permitting strategy.
BTEX Only two instances of detection for these parameters noted during the
period of review, and these were not significant. Reduced monitoring
to quarterly for each parameter.
MTBE Though it has been identified as a potential carcinogen, no standard
has been established for this parameter. Outfall showed 5 hits out of
47 samples during POR. One did equal the proposed water quality
standard for MTBE in water supply waters (12 ug/L); the other four
were well below. The last reported hit was in March 2004 (1.1 ug/L v.
MDL of 1.0). Based upon overall performance, especially most recent
performance, reduced monitoring to quarterly.

For all outfalls
A more detailed footnote has been added regarding the calculation of flow. Nothing has
changed in the matter of substance.
Because MTBE was detected at each outfall during the past permit cycle, and because the
facility did not submit,a MTBE action plan during the permit cycle, Colonial Pipeline will be
required to submit a plan to inform DWQ how it will work to reduce or eliminate the
discharge of MTBE in its effluent.

Re: Colonial Pipeline Company - Renewal Application

Mr. Guerra:
Telephone: [phone]
Facsimile: 336-292-6462
FEB 1 5 2006
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 five (5) outfalls at this facility that mainly treat stone 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. 1 have included a copy of our watershed runoff— effluent Flow with this application.
While we are in the renewal process, I respectfully request consideration for the following changes and/or amendments to our new
permit:
Because of new EPA regulations regarding sulfur content in diesel fuel, we are currently constructing two (2) new tanks at
this facility. They are both being built in the area of our facility that discharge through outfall 001, adding approximately
46,000 square feet of impervious surface in this area. This will result in an increase of approximately 7 percent (.07) to our
storm water discharge total through this outfall. This change will be included in the spreadsheet we use to calculate stone
water runoff using the rational method and a runoff coefficient of 50 percent. Included with this renewal package are blank
copies of the spreadsheets used to calculate storm water discharges based on rainfall results found in the Detailed Reports at

• Since we have never had a detection of the single -compound phenol in any of our discharge water samples, would like to
request that the monitoring frequency for phenol be reduced from monthly to semi-annually. This could be included with our
EPA 625 requirement. We feel that analyzing total phenolics as an indicator for phenol on a monthly basis adds little value.
Due to the sensitive characteristics of much laboratory analytical equipment, we would like for our benzene concentration
limit be increased from 1.19 micrograms per liter (ug/L) to 2.0 ug/L. There have been a few times in the past where our
discharge samples from certain outfalls have resulted in concentrations of benzene ranging from 1.2 ug/L to 1.6 ug/L,
resulting in non -compliances. Although we fully understand the need to protect all surface water bodies, especially WS-IV
classified waters, and we definitely do not want to have a negative impact on any of our receiving streams, it is somewhat
difficult to believe that there isn't laboratory error associated with some of these results. Also, since we have never had a
detection of benzene in any of our downstream samples, we believe that if these low levels of benzene truly are present, they
are dissipated/evaporated or fully diluted before they actually leave our property.

One last consideration involves Total Suspended Solids (TSS). Although we believe we have excellent Best Management
Practices (BMPs) implemented with regards to our erosion control program, there are times during significant rain events
where our TSS concentrations exceed our permit limit of 45 milligrams per liter (mg/L). However, even though we have had
minor exceedences, the concentrations from our outfalls are generally much lower than the concentrations from our upstream
samples. In addition, in most cases, the downstream samples are below our permit limit. I guess basically what I am trying
to say is that, although we have had exceedences from time to time, because the size of our main lakes and their retention
time capabilities, we have actually mitigated impacts to our downstream waters. I would like to include a condition or some
additional language in the permit that reads something like; "If the TSS concentration exceeds 45 mg/L due to natural
background conditions, the discharge level cannot cause any increase in the TSS concentration in the receiving water."
One of Colonial's core values is the protection of our environment and we certainly want to continue in our efforts to comply with all
permit limits and conditions and we also understand there are accountabilities to our neighbors and the public in general, as there
should be. I also realize I have looked into some of the above areas of concern from more of a practical standpoint and I certainly
don't want it to appear that we are asking for special allowances or concessions that would negatively impact the waters of the state or
our downstream neighbors. It may be that these permit conditions are non-negotiable and, if that's the case, I fully understand.
However, I would appreciate it if you could look into these requests and see if any of them could be considered.
Please note that we will continue discharging hydrostatic test water directly to the main lake after receiving results from representative
sampling that the water in the tank and/or pipe is below the permit limits for Benzene, Toluene, Ethyl Benzene and Xylene (BTEX).
As agreed upon in the past, this greatly reduces environmental impact because it removes the possibility of soil erosion that could
occur when discharging through the earthen dike areas. We will continue reporting hydrostatic test water discharges on individual
Discharge Monitoring Reports (DMRs) and they will be identified as "Hydrostatic Test Water — Tank # ????". An example of the
DMR is included with this package.
Thank you very much for your assistance with this permit renewal and also for considering our requests for changes. If you have
questions or require additional information, please contact me at [phone] or at the letterhead address.
Sincerely,
Faron D. Leigh
