Subject: Comments on Draft NPDES Permit NC0081469
Colonial Pipeline Company— RDU Delivery Facility
On behalf of Colonial Pipeline Company (Colonial), Resolve Environmental Engineering, Inc.
(Resolve) appreciates the opportunity to provide these comments on the proposed draft
renewal of NPDES Permit NC0081469 for the Colonial RDU Delivery Facility. This letter is in
response to the draft permit sent to Colonial dated July 11, 2023.
During a review of Discharge Monitoring Reports, it was determined that the reported
detection of total recoverable phenolics in a sample collected on August 22, 2022, was in error.
The laboratory analytical report for that sample is attached. As noted in the report, total
recoverable phenolics concentrations were below the laboratory detection limit of 0.020 mg/I.
Using this corrected data, there have been no detections of total recoverable phenolics during
the period reviewed by Resolve (since the start of 2021). Therefore, there is not a reasonable
concern that facility discharges of total recoverable phenolics have the potential to impa
instream water quality. We therefore request removal of the total recoverable phenolics permit
limit and removal of references to total recoverable phenolics in Part I.A.(5.) of the permit.
We note that, for EPA Method 625, Part I.A.(1.) of the permit lists a monitoring frequency of
"2/Year" and Part I.A.(4.)(a) lists a monitoring frequency of "Monthly". We request clarification
on the intended monitoring frequency. Resolve believes a monitoring frequency of 2/Year is
appropriate based upon past data. If NCDEQ believes a monitoring frequency of monthly is

appropriate, we request a copy of the Reasonable Potential Analysis (RPA) that was completed
to make this determination.
We understand the addition of postponed permit limits for toluene and naphthalene was based
upon detections of these parameters in the previous 12 months. We would like to receive a
copy of the RPAs that were completed for these parameters. We note that the facility is an
intermittent discharger, with discharges consisting substantially of stormwater runoff. We
believe that RPAs performed for this discharge should account for the intermittent nature of
the discharges.
We also note the permitted outfall receives stormwater runoff from offsite sources, including
roads, office buildings and parking areas on adjacent and nearby properties. The National
Urban Runoff Program determined that toluene and naphthalene are periodically found in
stormwater runoff from such urban developments. As part of the compliance reports required
under Part I.A.(5.) of the permit, Colonial may assess the impact of these offsite sources on
discharge parameters. If pollutant sources are located offsite, it may affect Colonial's ability to
control those sources.
Resolve appreciates the opportunity to submit these comments. If you require any
clarifications, please do not hesitate to contact Mr. Ian Lundberg of Resolve at 770-650-9990 or
Mr. David Reedy of Colonial at 678-213-7365.
Sincerely,

QUALIFIERS
Project: RDU Delivery Monthly
Pace Project No.: 92621734
DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit. •
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
B3 The dissolved oxygen depletion of the dilution water blank exceeded 0.2 mg/L.
H3 Sample was received or analysis requested beyond the recognized method holding time.
L1 Analyte recovery in the laboratory control sample(LCS)was above QC limits. Results for this analyte in associated
samples may be biased high.
L2 Analyte recovery in the laboratory control sample(LCS)was below QC limits. Results for this analyte in associated
samples may be biased low.
MO Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.
R1 RPD value was outside control limits.
R6 The RPD between valid sample dilutions exceeded 30%.
SO Surrogate recovery outside laboratory control limits.
