Subject: Issuance of NPDES Permit NCO046213
Marathon Petroleum Company, LLC
Charlotte Terminal
Mecklenburg County
Dear Mr. Baker.
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 the following change from the draft permit sent to you on July 20, 2005:
• Because the Environmental Protection Agency has tagged MTBE as a potential carcinogen and
this discharge is to water -supply waters, MTBE monitoring has been included in this permit
Effluent data gathered in recent years consistently shows MTBE to be below detection levels, so
the monitoring frequency required will be quarterly rather than monthly.
If anyparts, 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 Marl Service Center, Raleigh,
North Carolina 27699-6714). Unless such demand is made, this decision 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 other permits which may be required by the Division of Water Quality or permits required by the
Division of Land Resources, the Coastal Area Management Act or any other Federal or Local governmental permit
that may be required. If you have any questions concerning this permit, please contact Dawn Jeffries at telephone
number [phone], extension 595.
Sincerely,
zi(-V4�

Footnotes:
1. Flow — During periods of no flow, the Permittee shall submit a monthly Discharge Monitoring Report
(I)MR) indicating "No discharge." Flow shall be monitored with each discharge event in one of
four ways:
a) measure flow continuously;
b) calculate flow based on total rainfall per area draining to the outfall; exclude built -upon
area (best method for facilities with large runoff -collection ponds, see A. (3.) for rational
equation);
c) estimate flow at 20-minute intervals during the entire discharge event; or
d) report flow based on discharge pump logs.
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. Turbidity — 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.
4. Naphthalene — Monitoring requirement applies to facilities that store, or historically stored, diesel or
other heavy fuels on site.
5. Acute Toxicity (Fathead Minnow, 24-hour), Annual [see Special Condition A.(2.)]. Permit holder
shall sample for acute toxicity And BTEX concurrently.
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 µg1l and toluene concentration is less than 11 jig/I.

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2.) 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.

Permit NCO046213
A. (3.) RATIONAL EQUATION
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)
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.

BACKGROUND
This oil terminal stores more than one million gallons of petroleum products and discharges stormwater from
one outfall. Water from the loading rack area goes through an oil/water separator and then to a holding tank. From
there it is disposed of off -site. The permit was last renewed in 2001 and expires June 30, 2005.
FILE REVIEW
Correspondence
The Mecklenburg County Department of Environmental Protection (MCDEP) conducts annual inspections at
this facility as part of a cooperative working agreement between the county and DWQ. Inspection records (2003-2005)
indicate satisfactory ratings in all inspected areas. The facility has not received any notices of violation or enforcement
actions in the past permit term.
DMR Review:
DMRs were reviewed from April 2003 through March 2005. Discharges are sporadic in nature; the mean flow
for those months in which there was discharge was 0.113 MGD. The maximum flow (used below in the reasonable
potential calculations) was 0.405 MGD. Total suspended solids during this time averaged 11.1 mg/L with a maximum
of 44.0 mg/L. All oil and grease effluent sample concentrations were less than the detection level except for one
detection of 12.0 mg/1.
The permit requires monthly monitoring for BTEX, turbidity, phenol, and MTBE. These are addressed below
in the RPA section. The twice -annual EPA 624/625 scan revealed non -detects for all additional parameters of concern.
The facility has passed all its annual acute toxicity tests since the 2001 permit renewal.
Reasonable Potential Analysis:
Data were analyzed for benzene, xylene, toluene, ethyl benzene, phenol, MTBE, and turbidity. All samples for
benzene, toluene, xylene, ethylbenzene, phenol, and MTBE were below detection level. The reasonable potential
analysis for turbidity predicted a maximum effluent turbidity of 236.5 NTU, which is above the allowable 50 NTU,
therefore a limit of 50 NTU will be added.

PERMITTING STRATEGY
The permitting strategy for this and all oil terminals in the state is based upon a document entitled, "NPDES
Permitting Requirements for Discharges for Petroleum Bulk Storage, Surface Storage Greater than One Million
Gallons, 2005-Permitting Strategy Addendum." This document is based upon a 2001 SOP and has been updated after a
data review and internal discussions. It delineates monitoring frequencies and permitting limits for contaminants
commonly found at these sites. Below, it is referred to as the "2005 Permitting Strategy."
Oil Terminal SOP:
Requirements specified in the previous permit remain largely unchanged. Turbidity showed reasonable
potential and therefore a 50 NTU limit will be added. Benzene, toluene, ethyl benzene, xylene, and phenol showed no
potential to exceed water quality standards. All samples for these parameters for the past two years were below
detection level except for one detection of ethylbenzene at 1.1 µg/L in August 2004. Monitoring requirements will
remain in the permits without limits, and will be will be decreased from monthly to quarterly due to the lack of
detections. The maximum allowable concentration for phenol was calculated using the maximum monthly average flow
discharged for the evaluation period (0.405 MGD) and the allocation of 0.43 lb/day for each discharger in this area.
MTBE will be removed from the permit per the 2005 permitting strategy. As per parts I.G. and I.H. of the 2001 SOP,
there can be no direct discharge of tanks solids, tank bottom water or the rag layer, and no direct discharge of
hydrostatic test water if concentrations of benzene and/or toluene exceed the water quality standard.
SUMMARY OF PROPOSED CHANGES
Addition of turbidity limit
• Removal of benzene limit
Reduction of monthly monitoring for phenol and BTEX from monthly to quarterly
• Remove requirement for Method 625 scans based upon 2005 permitting strategy
Add monthly monitoring for naphthalene

Marathon Ashland Petroleum (MAP) offers the following administrative comments to the draft NPDES
permit (#NC0046213) received in late July of 2005:
The physical address of the facility is now referred to as 8035 Mt. Holly Road, Charlotte, rather
than the previous address of 8035 Mt. Holly Road, Paw Creek, following an annexation.
MAP will officially change our corporate name to Marathon Petroleum Company LLC on
September 1, 2005. Mr. Charles Weaver advised that the NCDENR "Permit Name Change Form"
cannot be submitted prior to that date. The completed form will be mailed to the NCDENR in
early September.
Your cover letter dated July 20, 2005 references "Davie County". I assume this was a
typographical error as the county is properly referred to as Mecklenburg throughout the draft
permit.
If you have any questions or need additional information, please call me at 615/258-4421 or contact me via

RE: NPDES Permit Renewal — NCO046213
Marathon Ashland Petroleum LLC — Charlotte Terminal
8035 Mt. Holly Road, State Hwy #27, Paw Creek, NC 28130
Dear Mr. Weaver:
Marathon Ashland Petroleum (MAP) requests to renew the subject NPDES permit. Enclosed please find
one (1) original and two (2) copies of the completed Short Form C Permit Application. In accordance with
the requirements of the renewal package, please note the following:
There have been no substantive changes to the facility since the last renewal.
The permit application requests coverage of controlled stormwater discharges. No sanitary,
cooling water, or process water is discharged to surface waters.
The facility does not generate any solids. Therefore, a sludge management plan has not been
developed.
If you have any questions or need additional information, please call me at 615/258-4421 or contact me via
Email at [e-mail].
Sincerely,
e
Bernie Sharkey
