RE Biodegradation Enhancement Work Plan and BS/SVE System Termination
Marathon Charlotte East Terminal -Paw Creek
(Formerly BP/Southeast Terminals No. 4762)
7401 Old Mount Holly Road
Charlotte, North Carolina
AECOM Project #60566854
Dear Mr. Taraban:
In response to the North Carolina Department of Environmental Quality (NCDEQ) letter dated
November 8, 2018 (Attachment 1 ), this correspondence provides detailed information on use of Oxygen
Releasing Compounds™ (ORC) socks, or equivalent, for use as a remedial alternative at the referenced
sites. Background information can be found in the 1st Half 2018 Active Remediation Monitoring Report for
the Marathon Petroleum Company, LP bulk-fuel storage terminal (formerly BP/Southeast Terminals) in
Charlotte, North Carolina, dated September 28, 2018. As ORC is a viable alternative in discussion with
NCDEQ, and based on years of analytical and hydrogeologic data indicating a stable footprint of
chemicals of concern (COCs), the active remediation system has remained off since the December 2018
semi-annual sampling event pending approval of the work and subsequent submittal of installation of filter
socks in early 2019.
Brief Backg round:
The project site is located in an industrial setting (Figure 1) and a Site Plan has been included as
Figure 2. Based on Site boring logs, subsurface materials at the Site consist of soil and saprolite
overburden, including silty/clayey sand, sandy clay/silt, and silt/clay, which overlie weathered and
competent bedrock. Bedrock, meeting the description of metamorphosed quartz diorite referenced above,
has been encountered in Site borings at depths ranging from approximately 10 to 40 feet below grade.
Groundwater in the Piedmont province occurs in the overburden under unconfined (i.e., water table)
conditions and in the underlying bedrock under both unconfined and confined conditions. Groundwater in
the overburden occurs within pore spaces of the unconsolidated medium, including relict bedrock
structures (e.g., fractures, foliations, etc.). Due to the typically fine-grained nature and low permeability of
saprolite, the formation is not usually utilized for groundwater production. Monitoring wells in the area of
concern are approximately 20 feet in depth with depth to groundwater between 4 and 9 feet subgrade
(Table 1 and Table 2). Groundwater flow direction is consistently to the south-southwest (Figure 3). Four
wells have exceedances of benzene or semi-volatiles, and are located in the interior of the site (Figure 4).
There is one known potable water supply well within 1,500 feet and downgradient of the Site. The well is
located at 6516/6518 Freedom Drive and is approximately 1,220 feet from the targeted remediation area.
A BIOSCREEN fate and transport model was constructed for the Site in 2017 (1st Half 2017 Active
Remediation Monitoring Report, AECOM, September 29, 2017).The BIOSCREEN model was constructed
incorporating physical site data where available, and typical or literature values where site specific data
was not available. Site history and observed concentrations were used to calibrate the model before future
off-site predictions were made with the model. Concentrations at the 1 ug/L level (NC 2L) are expected to
reach a distance of 950 ft from edge of the source area (i.e., MW21 area) and would extend approximately
750 feet south of the current property boundary, past MW02, assuming no degradation at 30 years.
However, allowing for 1st order decay, the NC 2L is expected to be met nearer the property line. Therefore,
AECOM
based upon the limited travel of benzene using 1st order decay shown to reach 1 ug/1, offsite occurrence of
benzene above GCLs (5,000 ug/1) was found not likely.
The site has undergone over 9 years of pump and treat, 6 years of dual phase vapor extraction (DPVE),
and 2 years of biosparging (BS). Efforts have been made to reduce analytical concentrations in the vicinity
of MW21, however, benzene concentrations continue to increase likely due to contamination underneath
an adjacent and wide utility corridor that cannot be safely accessed or remediated . Exterior wells outside
the utility corridor are below gross contaminant levels (GCLS) and have asymptotic or decreasing
concentrations . The biosparge system operation has reached a point of diminishing return and was
recently idled following the December 2018 sampling event to allow for alternative remedial efforts,
i.e., ORC.
Proposed Installation:
Four wells currently exceed GCLS: MW21, MW51 , MW65, and MW48. ORC filter socks are proposed as
an alternate remedial action. The filter socks contain oxygen release substrate and an inert carrier matrix.
The socks are laced together to span the vertical hydrocarbon impacted saturated zone. Once the socks
are laced together and lowered into the wells, they become hydrated and begin releasing oxygen.
Biodegradation of organic COCs involves processes of microbial metabolism, whereby naturally occurring
elements or compounds are reduced by accepting electrons produced by the oxidation of organic
compounds through metabolism. Dissolved oxygen (DO) is the most readily utilized electron acceptor for
aerobic biodegradation, and is generally the first electron acceptor utilized and depleted during
biodegradation. Following the depletion of dissolved oxygen, the biodegradation process becomes
anaerobic as nitrate, ferric iron, sulfate, and carbon dioxide are utilized, respectively, and converted to
metabolic by-products, including ferrous iron and methane.
Up to two, 2-inch inner diameter (ID) filter socks will be installed in interior wells MW48, MW-51, and
MW-65 to supply oxygen for naturally occurring aerobic biodegradation. Up to four 2-inch ID filter socks
will be deployed in interior well MW21 . No more than four filter socks will be laced together and placed in
each well. The filter socks will be left in place for six months, or as determined as spent based on DO
measurements and/or COC concentrations . When spent , new filter socks will be installed.
Monitoring and Report:
Sixteen Type II monitoring wells are located in the area of concern with four wells , mentioned previously,
exceeding GCLS. DO will be measured quarterly from the sixteen wells to evaluate the effectiveness of
the filter socks to be placed in the four aforementioned wells. Filter socks will be installed/replaced twice a
year to start. Downhole dissolved oxygen will be measured quarterly. Semi-annual sampling will occur on
select wells as outline in Table 3. Wells will be sampled for benzene, toluene, ethylbenzene, and xylene
(BTEX) and/or SVOCs.
Reporting will occur semi-annually and will include installation , quarterly DO, and semi-annual sample
results. Following one year of sampling, recommendations may be made as to frequency of sampling and
reporting. Appropriate notification will be submitted to NCDEQ -Division of Water Quality (DWQ) prior to
installation and following approval of this work plan .

On August 3, 2018, a report titled Response to ind Half 201 7 Remediation Monitoring
Report (ATMR) dated April 2018, was submitted on your behalf by AECOM (formerly URS).
The report has been reviewed and will be maintained in the Mooresville Regional Office (MRO)
of the Division of Waste Management, Underground Storage Tank (UST) Section.
In the report AECOM notes that:
1. Benzene concentrations in the SVE effluent have declined significantly and reached
asymptotic concentrations;
2. Dissolved benzene concentrations in excess of Gross Contaminant Levels (GCLs) should
not reach the property boundaries, and that the plume is stable and attenuating;
3. Groundwater in MW-21, 51, and 65 continue to exceed the GCL for benzene;
4. MW-48 continues to exceed GCLs for semi-volatiles;
5. Impact to MW-21 is thought to be related to soil contamination in the adjoining utility
corridor;

6. Soil excavation, pump and treat, duel phase extraction, biosparging and soil vapor
extraction and in-situ chemical oxidation have been utilized at the site;
7. Approximately 6,500 gallons ofLNAPL have been recovered since 1985; and,
8. AECOM does not feel the further ISCO would be of value given the low permeability of
the soil and numerous utilities.
This office was notified that Marathon Petroleum wished to have a meeting to discuss the site.
An original meeting date was set and cancelled due to hurricane Michael. A subsequent in person
meeting was not possible in October due to a pest issue in the Mooresville Regional Office. A
teleconference was done earlier today as a best substitute for the meeting.
It was agreed that Marathon and TransMontaigne would submit a plan to continue remediation
by less aggressive means such as ORC compounds in existing wells. The goal of the new remedial
method shall be to continue reductions in dissolved constituents in wells MW-21, MW-48, MW-51, and
MW-65 such that they will be reduced to less than Gross Contaminant Levels. A written proposal to
discontinue biosparging and implement another remedial approach shall be submitted to this office
within the next 60 days.

4. HAZARDS IDENTIFICATION
Emergency overview
Oxidizing agent, contact with other material may cause fire. Under fire conditions this material may
decompose and release oxygen that intensifies fire. This product also contains crystalline silica. Long tern
exposure to hazardous levels of silica dusts can cause lung disease (silicosis). The World Health
Organization had indicated that there is limited evidence that crystalline silica is carcinogenic to humans,

0-SOX"
The Easiest Downwell Deployment of Dissolved Oxygen
Affordable and effective oxygen -
releasing socks for stimulating
aerobic biodegradation in ground
water wells.
Applications:
Stimulation of aerobic biodegradation of groundwater con-
taminants using EHC-0TM. El-IC-0 is deployed in ground
water wells with the 0-SOXTM delivery system.
EHC-0 is a proprietary field -proven compound that con-
tains a long-term source of dissolved oxygen and nutrients.
In the well, EHC-O reacts with water to release oxygen
slowly. Exhausted socks are easily replaced with new ones
to continue treatment.
Organic constituents amendable to aerobic biodegradation
processes are:
• Petroleum Hydrocarbons
• Light polycyclic aromatic hydrocarbons (PAHs)
BTEX
Benefits of EHC-DTM
Significant cost savings realized through the use
of EHC-O due to its higher oxygen release rate and
lower price.
Contains nutrients. pH -buffered to reduce self -en-
capsulation.
4. Estimated longevity of 3 to 6 months.

Benefits of O-SoxTM Delivery System
• All the field proven benefits of EHC-O.
Substantial time savings in
the field.
4. Reusable stainless steel
canisters are easy to insert in
and retrieve from the well. Re-
cover the cost of the canister
in your first installation!
Ease of determining the exact
depth at which the product is
deployed.
Socks and canisters available for 2" and 4" wells.
4. Up to three canisters may be suspended in line to
lengthen the active zone.
• Even distribution of the active material over the
length of the canister(s) because the socks do not
collapse or bunch up.

EHC-OT"' O-Soxt FAOs
1. What are the main differences between 0-Sox and comparable
market alternatives? EHC-C 0-SOX contains a well -buffered source
of controlled release oxygen plus inorganic nutrients (mainly nitrogen)
that can accelerate the biodegradation of various organic compounds
and enhance certain natural attenuation processes. In addition, the
0-SOX technology is a superbly well designed stainless steel canister
and sleeve system which greatly simplifies installation, removal and
replacement.
2. Do I need microbial inoculants? In most cases, the naturally oc-
curring (indigenous) microorganisms are well adapted to the organic
constituents of interest and inoculants are not required.
3. What contaminants are amenable to 0-Sox treatment? The rate
and extent of removal of all organic compounds that are biodegraded
under aerobic conditions are usually enhanced via the addition of
oxygen and inorganic nutrients. Petroleum -based aromatic (e.g.,
benzene, toluene, xylene, phenol) and aliphatic hydrocarbon mixtures
(e.g., gasoline, heating oil. Diesel fuel, jet fuel, kerosene) are primarity
targets; lightly chlorinated ethenes (vinyl chloride). MTBE, dioxane,
pentachlorophenol, and many other compounds are also potentially
amenable to 0-Sox treatment.
4. How much do they cost? 0-SOX cost about 25% less than market
alternatives.
5. Why should i use the 0-Sox technology? It's a better product. And
The superior design and ease of application will immediately franstate
into greatly reduced field time and frustration = reduced project cost.
6. Is It easy to switch over to the 0-Sox technology? Yes. EHC-O
has been accepted by many state regulatory authorities and it has
been employed throughout the USA and Europe.
7. How long do they last? 0-SOX are typically replaced every 3 to
6 months. Various site -specific factors will influence the effective life-
time of the 0-SOX cartridge; mainly I) constituent type and concentra-
tion, and ii) hydrogeological features (groundwater flow rate, Eh, pH.
temperature).
8. Do I need to install new wells? No. The 0-SOX technology is
designed to flt into standard 2-inch and 4-inch diameter groundwater
monitoring wells. The canisters have a nominal outside diameter of
1.75 inches for the 2-inch size and 3.5-inches for the 4-inch size.
9. What is the oxygen delivery rate? The rated delivery is at least 15 Ib
of oxygen per 1001b of EHC-0, after 200 days.
