CONTINUED (MODIFIED) ENHANCED ANEAROBIC BIOREMEDIATION (EAB) PILOT TESTING
Former Flint Hills Resources, LP (FHR) North Terminal Loading Rack (LR) Area
NCDEQ UIC Permit No. W10800455
1.0 Purpose and Background
Continued (Modified) Enhanced Anaerobic Bioremediation (EAB) Pilot Testing for in -situ remediatian
of pars-xylene (PX) concentrations in the residual source zone (i.e., smear zone) and shallow
groundwater (i.e., dissolved PX).
Permitted EAB Pilot Test activities conducted between the dates of June 2016 and January 2017 at the
former Flint Hills Resources, LP (FHR), North Terminal, Loading Rack (LR) Area, located in Wilmington,
North Carolina (Site) (NCDEQ Incident No. 16971) involved injecting a solution of Epsom Salt into the
residual PX source area (i.e., area proximal to monitoring well KMW-6) via 3 injection wells (TRC IW-1,
TRC IW-2 and 51-11). The three (3) EAB injection events conducted between the dates of June 14-16,
2016, August 33-September 1, 2016, and January 10-January 11, 2017 resulted in the following
observations and conclusions:
1. An observed decrease in PX concentrations in the residual PX source area, and in down -gradient
(western) monitoring wells (i.e., KMW-12 and KMW-13) as a result of providing a soluble sulfate
source to the anaerobic microbial community;
2. A lack of sulfate persistence in the Pilot Test study area;
3. Decreased concentrations of nitrogen needed to promote biological growth, and
4. Due to the high elevation of Site shallow groundwater (i.e., 1 to 3 ft below ground surface (bgs);
precipitation dependent), and sandy geology, a more efficient and effective method for
introducing amendments directly into the residual PX source area and shallow groundwater
would be through the installation and use of a shallow amendment recharge trench 15ART1
2.0 EAB Pilot Test Modifications
The continuing EAB Pilot Test activities described in this section represent a modification to existing
NCDEQ U!C Permit No. W10800455.
TRC Environmental Corporation (TRC), on behalf of Flint Hills Resources, LP, proposes the design and
installation of a SART proximal to the residual PX source area, and backfilling the SART with both 1) a
solid persistent sulfate source (i.e., an Epson Salt and gypsum mix), and 2) a soluble source of nitrogen.
Soluble forms of sulfate delivered to the residual PX source zone, and shallow groundwater serve as
electron -acceptors, and enhance the natural anaerobic degradation of the hydrocarbons. Epsom Salt
will represent approximately one half of the amendment (by weight), and is an NCDEQ approved
injectant. Gypsum will represent approximately one half of the amendment (by weight) but is not
currently an NCDEQ approved injectant. However, considering gypsum is a common building material
that is routinely introduced to the environment, environmental concerns regarding its use during EAB
Pilot Testing are minimal. The low solubility of gypsum (2 to 2.5 gfl) makes this material ideal for use as
a persistent sulfate source.
TRC also proposes introducing a soluble source of nitrogen to the study area to promote biological
growth. Groundwater sampling data suggest depletion of nitrogen in groundwater based upon analysis
of Total Kjeldahl Nitrogen (TKN). Ammonium Phosphate (a NCDEQ approved injectant) will be added as
1

C)ITRC
Reviler you ran My an
a soluble source of nitrogen. Ammonium phosphate is listed as having a solubility of 62 grams per 100
ml of water (620,000 mg/I). TRC anticipates that Ammonium Phosphate solubility will be reduced
significantly as a result of mixing the nitrogen source with Epsom Salt and gypsum in the capillary fringe.
TRC also requests NCDEQ approval to substitute Diammonium Phosphate (DAPS as a nitrogen source as
it is more stable than ammonium phosphate, widely used as a fertilizer, and will produce the sarne
result (i.e., dissolved phosphorus and ammonia constituents).
As gypsum and DAP are not on the NCDEQ approved injectant list, TRC has included the following
information as Attachments 8a through Se to facilitate NCDEQ approval of gypsum and DAP as
injectants for use during continuing EAB Pilot testing at the Site:
Material Safety Data Sheet (MSDS) for gypsum (8a);
MSDS for DAP (8b);
A completed NCDEQ Risk Assessment Evaluation for Groundwater or Soil Remediation Additives
Containing No Microorganisms (Form GW/UIC-3, Revised Oct 13, 2014) for gypsum (8c);
A completed NCDEQ Risk Assessment Evaluation for Groundwater or Soil Remediation Additives
Containing No Microorganisms (Form GW/IUIC-3, Revised Oct 13, 2014) for DAP (8d); and
A map of the Cape Fear Public Utility Authority (CFPLJA) City of Wilmington Water Service Area (8e).
3.0 Implementation of Modified EAB Pilot Testing
Details specific to implementation of the proposed modified EAB pilot testing at the Site are presented
below.
Shallow Amendment Recharge Trench (SART) Installation (Proposed New Activity) (Ref. Attachment 5]
Field locate all subsurface utilities proximal to the study area, and the SART footprint;
Hand dig in areas of suspected utilities proximal to the SART (i.e., former PX pipeline and storm
sewer pipeline (5" PVC);
Install one (1) SART (50 feet long, x 1.5 feet wide x 5 deep) (Ref. Attachment 5) using a mini -
excavator;
Stockpile non -saturated overburden for use as surficial fill during SART restoration activities;
Backfill the SART at depth with 4,000 pounds of Epsom Salt, 4,000 pounds of gypsum, and 300
pounds of ammonium phosphate (or diammonium phosphate if approved by NCDEQ MC) using the
mini -excavator (i.e_, mechanical blending at depth). Note: As saturated soils will be mechanically
blended in -situ (i.e., within the SART) with solid amendments, accumulation, characterization, and
off -site transportation and disposal of saturated soils (SART, 3ft to 5ft bgs) will not be required); and
Backfill and restore the SART to existing grade using stockpiled non -saturated overburden.
Notes:
1. Installation of the SART will be performed in Level D personal protective equipment (PPE). Hand
digging at grade may occur to locate the top of utilities at grade. No personnel will enter the
SART during installation. As outlined above all solid amendments will be mechanically blended
at depth using a mini -excavator (Approx. 3ft to 5ft bgs); and
2. Based on amendment utilizations rates and groundwater monitoring results, the SART may
require amendment replenishment/recharge during the LAB Pilot Testing project schedule. At
present, TRC estimates SART replenishment/recharge approximately every 6-months.

EAB Groundwater Amendments Utilizing Injection Wells (Permitted Activity)
Perform up to six (6) EAB groundwater amendment injection events, approximately once every
three months. EAB injections events will utilize the same injection wells previously permitted by
NCDEQ (i.e., TRC IW-1, TRC IW-2, SI-11, and SI-12);
Magnesium Sulfate (Epsom Salt), an NCDEQ-approved injectant, will continue to be used as the
soluble sulfate source. Additionally, a soluble nitrogen source, either ammonium phosphate or
diammonium phosphate, will be added to the amendment to promote biological growth;
The injection well headers previously constructed for amendment delivery will be utilized to connect
to the injection wells and deliver amendment directly to the target shallow groundwater zone;
Mixing and delivery of the groundwater amendment will continue to be via tanker truck;
Potable water will be used to dilute and mix the Epsom Salt and nitrogen amendment solution.
Potable water will continue to be obtained from the ChemServe facility hydrant which is capable of
delivering water at the required minimum of 100 gallons per minute (gpm);
Daily quantities of required injectants will be mixed with potable water in a 5,000 gallon tanker
truck;
An injection manifold system will be used to monitor, control, and route the amendment during
injection operations. The injection manifold system and each well point wilt continue to use in -line
pressure gauges and flow meters installed for safety, observation, and measurement purposes. The
pressure gauges will be monitored to prevent excessive back pressures and to ensure the targeted
injection pressures are maintained throughout the injections. Totalizing flow meters will record the
total amount of amendment injected into each injection well during each injection event;
The amendment will be gravity fed or pumped (if necessary) through a manifold into the injection
wells at an estimated injection flow rate of 3 to S gpm at pressures of approximately 5 to 15 pounds
per square inch (psi). Sequencing of well amendments will be determined in the field based upon
aquifer response at the time of injection;
During each EAB injection event, real time electronic water level elevation measurements via water
level meter will be recorded at 5 groundwater monitoring wells to evaluate any changes in water
elevations during injection activities. These measurements will be collected at least three times per
day with one round of baseline measurements performed for comparative purposes. The results of
the water level measurements will be used to further assess the effective radius of influence and/or
modify the on -going injection as needed based on field conditions. Should instrument readings
confirm significant groundwater mounding at the above referenced wells (i.e., greater than 3 foot
increase in groundwater elevation), and/or if it appears that groundwater surfacing may be likely,
injection flow rates will be reduced and/or injection ceased until the groundwater levels stabilize to
pre -injection levels;
Monitoring for visual observations of amendment and groundwater surfacing (i.e., day -lighting) will
be performed. If day -lighting becomes an issue during the injections, injection pressure(s) and/or
Flow rate will be reduced or temporarily ceased to immediately mitigate the surfacing liquid. Any
surfacing liquids will be contained by the placement of liquid -impervious sand bags around the day -
lighted materials, placing an inert, chemically compatible absorbent material (i.e., sand, speedy dry,
etc.), and the materials cleaned up and disposed in accordance with the MSDS sheets; and
Real time measurements of pH, temperature, oxygen reduction potential (ORP), and specific
conductivity via dedicated trolls or a Hariba water quality meter will be recorded at 5 groundwater
monitoring wells to evaluate any changes in these parameters during EAB injection activities. This
data will be collected and recorded at least 3 times per day in addition to one round of baseline
measurements for comparative purposes.

EAB Pilot Test Groundwater Monitoring (Permitted Activity)
Groundwater monitoring will be conducted approximately seven (7) weeks following each EAB injection
event, however, the groundwater monitoring schedule is subject to modification based on observations
made during each EAB injection event. Groundwater monitoring activities will continue to consist of the
following (also Ref. Attachment 7):
Following equilibration to atmospheric temperature and pressure, collect one round of groundwater
elevation measurements at 8 groundwater monitoring wells;
Perform tow -flow groundwater sampling at 8 groundwater monitoring wells. A portable stainless
steel bladder pump or equivalent with a new section of polyethylene tubing will be used to sample
each groundwater monitoring well. Each well will be purged at a rate of 200-400 milliliters per
minute (mL/min) until stabilization parameters are met (i.e., ORP, pH, temperature, dissolved
oxygen, turbidity, and specific conductance). Samples to be collected for dissolved metals
concentrations will be field -filtered using a 0.45-micron in -line filter; and
Groundwater samples collected from each monitoring well will be analyzed for PX (82608), total
organic carbon (TOC) (9060A), sulfate (SO4) (9056A), total kjeldahl nitrogen (TKN) (351.2), alkalinity
(SM 2320B-2011), and magnesium (6010C)_

ATTACHMENT 7
Modified EAB Pilot Test Monitoring Plan
This monitoring plan will be conducted simultaneously and following each EAB injection event, and
during SART installation and replenishment/recharge events.
EAB Injection Event Real Time Monitoring
1. Groundwater Elevational Monitoring
Groundwater elevation monitoring will be performed during each EAB injection event to
evaluate if mounding is occurring. Groundwater elevations will be collected at least four times
each day during injection as follows:
• Pre -injection baseline groundwater elevation measurement
• Three additional times during injection
Groundwater elevation monitoring will be performed for the following wells:
• KMW-6, KMW-7, KMW-8, KMW-12 and KMW-13
2. Surface Monitoring
Monitoring for visual observations of solution surfacing "day -lighting" to the ground surface of
any injected amendment or groundwater will be performed. If day -fighting becomes an issue
during the injections, injection pressure(s) and/or flow rate will be reduced or temporarily
ceased to immediately mitigate the surfacing liquid. Any liquids shall be contained by the
placement of liquid -impervious sand bags around the day -lighted materials, placing an inert,
chemically compatible absorbent material (sand, speedy dry, etc.) and the materials cleaned up
and disposed of in accordance with the MSDS sheets.
3. Field Parameter Monitoring
Monitor select wells for the following parameters on a monthly basis with the intent to capture
groundwater elevations following precipitation events, when feasible:
• pH, temperature, oxygen reduction potential, and specific conductivity
The following wells will be monitored for field parameters:
• KMW-6, KMW-7, KMW-8, KMW-12 and KMW-13
SART Monitoring & Replenishment/Recharge
As stated previously in the application, this pilot test modification involves slow release, via a SART, of
soluble sulfate and a nitrogen source to promote biodegradation of paraxylene (PX) in the residual PX
source zone and shallow groundwater. Subsidence of the SART will occur as the amendments dissolve
into groundwater. TRC will replenish/recharge the SART as needed. The anticipated SART
replenishment/recharge schedule is once every 6 months.
1

Results you tall rely on
Additionally, groundwater elevation monitoring will be performed in wells proximal to the SART to
evaluate fluctuation in groundwater elevation relative to the base elevation of the SART. Groundwater
elevation measurements will be collected on a monthly basis for the following wells:
■ KMW-6, KMW-7, KMW-8, KMW-12 and KMW 13
Breathing Zone Monitoring
Field representatives will conduct periodic field screening of the breathing zone within the EAB pilot test
work zone. Field monitoring will consist of field screening for organic vapor concentrations using a
photoionization detector (P1D).
Groundwater Sampling
Groundwater sampling will be performed 7 weeks following each EAB injection event. Groundwater
samples will be collected at monitoring wells KMW-6, KMW-8, KMW-12, and KMW-13. Analytical
parameters wilt include PX, Sulfate, Total Kjeldahl Nitrogen, TOC, Alkalinity, and magnesium.

Section 3 - HAZARD IDENTIFICATION
Potential Health Effects
Relevant Routes of Exposure:
Eye contact, skin contact, inhalation, and ingestion.
Effects Resulting from E%c Contact:
Exposure to airborne dust may cause immediate or delayed irritation or inflammation. Eye contact by large amounts of dry
powder or splashes of wet gypsum dust may cause eye irritation. Such exposures may require immediate first aid (sec Section 4)
and medical attention to prevent damage to the eye.
Effects Resulting from Skin Contact:
Direct contact may cause irritation by mechanical abrasion.
Effects Resulting from Inhalation:
Gypsum may contain trace amounts of free crystalline silica. Prolonged exposure to respirable free silica can aggravate other lung
conditions and cause silicosis, a disabling and potentially fatal lung disease.
Exposure to gypsum dust may cause irritation to the moist mucous membranes of the nose, throat, and upper respiratory system. It
may also leave unpleasant deposits in the nose.
Effects Resulting from Ingestion:
Although small quantities of dust are not known to be harmful, 311 effects are possible if larger quantities are consumed.
Carcinogenic potential:
Limestone is not listed as a carcinogen by NTP, OSHA, or IARC. It may however, contain trace amounts of substances listed as
carcinogens by these organizations.
Crystalline silica, which is a component of limestone, is now classified by IARC as known human carcinogen (Group 1). NTP
has characterized respirable silica as "reasonably anticipated to be [a] carcinogen".
Medical conditions which may be aggravated be, inhalation or dermal exposure:

Pre-existing upper respiratory and lung diseases.
Section 4 -FIRST AID
Eyes
Immediately flush eyes thoroughly with water. Continue flushing eye for at least 15 minutes, including under lids, to remove all
particles. Call physician if irritation persists or later develops.
Skin
Wash skin with cool water and pH-neutral soap or a mild detergent. Seek medical treatment if irritation persists or later develops.
Inhalation of Airborne Dust
Remove to fresh air. Seek medical help if coughing and other symptoms do not subside.
Ingestion
Do not induce vomiting. If conscious, have the victim drink plenty of water and call a physician immediately.

data located for diammonium phosphate.
Chronic exposure to high concentrations of iron have been associated with
hemosiderosis, hemochromatosis and in severe cases, liver cirrhosis. Typical
occupational exposures to iron compounds are not expected to cause these effects.
Chronic inhalation can produce "mottling" of the lungs (siderosis). This is considered a
benign pneumoconiosis and does not normally lead to fibrosis or cause significant
physiologic impairment.
12.ECOLOGICAL INFORMATION
Ecotoxicity:
May release ammonium ions that are toxic to fish. Unionized ammonia concentrations >
0.02 mg/1 are considered toxic in fresh water. May release phosphates whichwlllresult
in algae growth, increased turbidity, and depleted oxygen. At extremely high
concentrations, this may be hazardous to fish or other marine organisms. Release to
watercourses maycause effects downstream. LC50 Salrno gairdneri- 160-230 mg/1; LC

Page 2 of 4
The Cape Fear River represents a hydraulic boundary for groundwater. There are no
known water intakes on the Cape Fear River within 1 mile of the Site, and no existing
production wells on the APEX Oil Terminal property.
Served by Public Water Supply: Yes. Cape Fear Public Utility Authority (CFPUA), City
of Wilmington, Water Service Area (Ref Attachment 8e).
5. General description of the contaminants if present in the soil and/or groundwater at the
site.
Site remediation involves addressing concentrations of paraxylene (PX) in the residual
PX source zone and shallow groundwater via in-situ enhanced anaerobic bioremediation
(EAB). The highest PX concentration for the project remedial area is in the vicinity of
monitoring well KMW-6 (i.e., the residual PX source zone). Previous EAB pilot test
activities have indicated that in-situ EAB amendments remain proximal to the general
remediation area, and are currently permitted to consist of amending groundwater with a
soluble form of sulfate in the form of Epsom Salt.
6. Name, approximate distance, and likelihood of impact to the nearest body of surface
water to the site.
The Cape Fear River is located approximately 1,300 lnft west (downgradient) of the Sites
western property boundary. Groundwater concentrations of PX attenuate from the
highest concentration of 14,000 ug/1 (April 2017) at monitoring well KMW-6 to 57.1 ug/1
at AMW-3 located approximately 450 ft. west (downgradient) ofKMW-6 on the APEX
Oil Terminal property. Assuming Site specific sulfate utilization rates remain consistent
with those observed during previous EAB pilot test activities (June 2016 to January
20017), there is a low probability that groundwater amendments will reach AMW-3, and
subsequently the Cape Fear River.
7. Approximate distance to nearest residence(s) and workplace.
The Site is located in a heavily industrialized area. There are no residential areas
downgradient (west) of the Site. The APEX Oil Terminal is located directly west
(downgradient) of the Site. The closest residential area is located approximately 1,550
lnft to the east (upgradient).

known water intakes on the Cape Fear River within 1 mile of the Site, and no existing
production wells on the APEX Oil Terminal property.
Served by Public Water Supply: Yes. Cape Fear Public Utility Authority (CFPUA), City
of Wilmington, Water Service Area (Ref Attachment 8e).
5. General description of the contaminants if present in the soil and/or groundwater at the
site.
Site remediation involves addressing concentrations of paraxylene (PX) in the residual
PX source zone and shallow groundwater via in-situ enhanced anaerobic bioremediation
(EAB). The highest PX concentration for the project remedial area is in the vicinity of
monitoring well KMW-6 (i.e., the residual PX source zone). Previous EAB pilot test
activities have indicated that in-situ EAB amendments remain proximal to the general
remediation area, and are currently permitted to consist of amending groundwater with a
soluble form of sulfate in the form of Epsom Salt.
6. Name, approximate distance, and likelihood of impact to the nearest body of surface
water to the site.
The Cape Fear River is located approximately 1,300 lnft west (downgradient) of the Sites
western property boundary. Groundwater concentrations of PX attenuate from the
highest concentration of 14,000 ug/1 (April 201 7) at monitoring well KMW-6 to 57 .1 ug/1
at AMW-3 located approximately 450 ft. west (downgradient) ofKMW-6 on the APEX
Oil Terminal property. Assuming Site specific sulfate utilization rates remain consistent
with those observed during previous EAB pilot test activities (June 2016 to January
20017), there is a low probability that groundwater amendments will reach AMW-3, and
subsequently the Cape Fear River.
7 . Approximate distance to nearest residence(s) and workplace.
The Site is located in a heavily industrialized area. There are no residential areas
downgradient (west) of the Site. The APEX Oil Terminal is located directly west
( downgradient) of the Site. The closest residential area is located approximately 1,550
lnft to the east (upgradient).

CONTINUED (MODIFIED) ENHANCED ANEAROBIC BIOREMEDIATION (EAB) PILOT TESTING
Former Flint Hills Resources, LP (FHR) North Terminal Loading Rack (LR) Area
NCDEQ UIC Permit No. W/0800455
1.0 Purpose and Background
Continued {Modified) Enhanced Anaerobic Bioremediation (EAB) Pilot Testing for in-situ remediation
of para-xylene {PX) concentrations in the residual source zone (i.e., smear zone) and shallow
groundwater (i.e., dissolved PX).
Permitted EAB Pilot Test activities conducted between the dates of June 2016 and January 2017 at the
former Flint Hills Resources, LP (FHR), North Terminal, Loading Rack (LR) Area, located in Wilmington,
North Carolina (Site) (NCDEQ Incident No. 16971) involved injecting a solution of Epsom Salt into the
residual PX source area (i.e., area proximal to monitoring well KMW-6) via 3 injection wells (TRC IW-1,
TRC IW-2 and 51-11). The three (3) EAB injection events conducted between the dates of June 14-16,
2016, August 30-September 1, 2016, and January 10-January 11, 2017 resulted in the following
observations and conclusions:
1. An observed decrease in PX concentrations in the residual PX source area, and in down-gradient
(western) monitoring wells (i.e., KMW-12 and KMW-13) as a result of providing a soluble sulfate
source to the anaerobic microbial community;
2. A lack of sulfate persistence in the Pilot Test study area;
3. Decreased concentrations of nitrogen needed to promote biological growth, and
4. Due to the high elevation of Site shallow groundwater (i.e., 1 to 3 ft below ground surface (bgs);
precipitation dependent), and sandy geology, a more efficient and effective method for
introducing amendments directly into the residual PX source area and shallow groundwater
would be through the installation and use of a shallow amendment recharge trench (SAR TI.
2.0 EAB Pilot Test Modifications
The continuing EAB Pilot Test activities described in this section represent a modification to existing
NCDEQ UIC Permit No. W/0800455.
TRC Environmental Corporation (TRC), on behalf of Flint Hills Resources, LP, proposes the design and
installation of a SART proximal to the residual PX source area, and backfilling the SART with both 1) a
solid persistent sulfate source (i.e., an Epson Salt and gypsum mix), and 2) a soluble source of nitrogen.
Soluble forms of sulfate delivered to the residual PX source zone, and shallow groundwater serve as
electron-acceptors, and enhance the natural anaerobic degradation of the hydrocarbons. Epsom Salt
will represent approximately one half of the amendment (by weight), and is an NCDEQ approved
injectant. Gypsum will represent approximately one half of the amendment (by weight) but is not
currently an NCDEQ approved injectant. However, considering gypsum is a common building material
that is routinely introduced to the environment, environmental concerns regarding its use during EAB
Pilot Testing are minimal. The low solubility of gypsum (2 to 2.5 g/I) makes this material ideal for use as
a persistent sulfate source.
TRC also proposes introducing a soluble source of nitrogen to the study area to promote biological
growth. Groundwater sampling data suggest depletion of nitrogen in groundwater based upon analysis
ofTotal Kjeldahl Nitrogen (TKN). Ammonium Phosphate (a NCDEQ approved injectant) will be added as
1
(C.. TRC
�. mi.,'
a soluble source of nitrogen. Ammonium phosphate is listed as having a solubility of 62 grams per 100
ml of water (620,000 mg/$). TRC anticipates that Ammonium Phosphate solubility will be reduced
significantly as a result of mixing the nitrogen source with Epsom Salt and gypsum in the capillary fringe.
TRC also requests NCDEQ approval to substitute ❑iammonium Phosphate (DAP) as a nitrogen source as
it is more stable than ammonium phosphate, widely used as a fertilizer, and will produce the same
result (i.e., dissolved phosphorus and ammonia constituents).
As gypsum and DAP are not on the NCDEQ approved injectant list, TRC has included the following
information as Attachments 8a through 8e to facilitate NCDEQ approval of gypsum and DAP as
injectants for use during continuing EAB Pilot testing at the Site:
Material Safety Data Sheet (MSDS) for gypsum (8a);
MSDS for DAP (8b);
A completed NCDEQ Risk Assessment Evaluation for Groundwater or Soil Remediation Additives
Containing No Microorganisms (Form GW/UIC-3, Revised Oct 13, 2014) for gypsum (8c);
A completed NCDEQ Risk Assessment Evaluation for Groundwater or Soil Remediation Additives
Containing No Microorganisms (Form GW/UIC-3, Revised Oct 13, 2014) for DAP (8d); and

Details specific to implementation of the proposed modified EAB pilot testing at the Site are presented
below.
Shallow Amendment Recharge Trench (SART) Installation (Proposed New Activity) (Ref. Attachment 5)
Field locate all subsurface utilities proximal to the study area, and the SART footprint;
Hand dig in areas of suspected utilities proximal to the SART (i.e., former PX pipeline and storm
sewer pipeline (6" PVC);
Install one (1) SART (50 feet long, x 1.5 feet wide x 5 deep) (Ref. Attachment 5) using a mini -
excavator;
Stockpile non -saturated overburden for use as surficial fill during SART restoration activities,
Backfill the SART at depth with 4,000 pounds of Epsom Salt, 4,000 pounds of gypsum, and 300
pounds of ammonium phosphate (or diammonium phosphate if approved by NCDEQ UIC) using the
mini -excavator (i.e., mechanical blending at depth). Note: As saturated soils will be mechanically
blended in -situ (i.e., within the SART) with solid amendments, accumulation, characterization, and
off -site transportation and disposal of saturated soils (SART, 3ft to 5ft bgs) will not be required); and
Backfill and restore the SART to existing grade using stockpiled non -saturated overburden.
Notes:
1. tnstallation of the SART will be performed in Level D personal protective equipment (PPE). Hand
digging at grade may occur to locate the top of utilities at grade. No personnel will enter the
SART during installation. As outlined above all solid amendments will be mechanically blended
at depth using a mini -excavator (Approx. 3ft to 5ft bgs); and
2. Based on amendment utilizations rates and groundwater monitoring results, the SART may
require amendment replenishment/recharge during the EAB Pilot Testing project schedule. At
present, TRC estimates SART replenishment/recharge approximately every 6-months.

0 IB9.
EAB Groundwater Amendments Utilizing Injection Wells (Permitted Activity)
Perform up to six (6) EAB groundwater amendment injection events, approximately once every
three months. EAB injections events will utilize the same injection wells previously permitted by
NCDEQ (i.e., TRC IW-1, TRC IW-2, Sl-11, and Sl-12);
Magnesium Sulfate (Epsom Salt), an NCDEQ-approved injectant, will continue to be used as the
soluble sulfate source . Additionally, a soluble nitrogen source, either ammonium phosphate or
diammonium phosphate, will be added to the amendment to promote biological growth;
The injection weli headers previously constructed for amendment delivery wiil be utilized to connect
to the injection wells and deliver amendment directly to the target shallow groundwater zone;
Mixing and delivery of the groundwater amendment will continue to be via tanker truck;
Potable water will be used to dilute and mix the Epsom Salt and nitrogen amendment solution.
Potable water will continue to be obtained from the ChemServe facility hydrant which is capable of
delivering water at the required minimum of 100 gallons per minute (gpm);
Daily quantities of required injectants will be mixed with potable water in a 5,000 gallon tanker
truck;
An injection manifold system will be used to monitor, control, and route the amendment during
injection operations. The injection manifold system and each well point will continue to use in-line
pressure gauges and flow meters installed for safety, observation, and measurement purposes . The
pressure gauges will be monitored to prevent excessive back pressures and to ensure the targeted
injection pressures are maintained throughout the injections. Totalizing flow meters will record the
total amount of amendment injected into each injection well during each injection event;
The amendment will be gravity fed or pumped (if necessary) through a manifold into the injection
wells at an estimated injection flow rate of 3 to 5 gpm at pressures of approximately 5 to 15 pounds
per square inch (psi). Sequencing of well amendments will be determined in the field based upon
aquifer response at the time of injection;
During each EAB injection event, real time electronic water level elevation measurements via water
level meter will be recorded at 5 groundwater monitoring wells to evaluate any changes in water
elevations during injection activities. These measurements will be collected at least three times per
day with one round of baseline measurements performed for comparative purposes. The results of
the water level measurements will be used to further assess the effective radius of influence and/or
modify the on-going injection as needed based on field conditions. Should instrument readings
confirm significant groundwater mounding at the above referenced wells (i.e., greater than 3 foot
increase in groundwater elevation), and/or if it appears that groundwater surfacing may be likely,
injection flow rates will be reduced and/or injection ceased until the groundwater levels stabilize to
pre-injection levels;
Monitoring for visual observations of amendment and groundwater surfacing (i.e., day-lighting) will
be performed. If day-lighting becomes an issue during the injections, injection pressure(s) and/or
flow rate will be reduced or temporarily ceased to immediately mitigate the surfacing liquid. Any
surfacing liquids will be contained by the placement of liquid-impervious sand bags around the day-
lighted materials, placing an inert, chemically compatible absorbent material (i.e., sand, speedy dry,
etc.), and the materials cleaned up and disposed in accordance with the MSDS sheets; and
Real time measurements of pH, temperature, oxygen reduction potential (ORP), and specific
conductivity via dedicated trolls or a Horiba water quality meter will be recorded at 5 groundwater
monitoring wells to evaluate any changes in these parameters during EAB injection activities. This
data will be collected and recorded at least 3 times per day in addition to one round of baseline
measurements for comparative purposes.
3
EAB Pilot Test Groundwater Monitoring (Permitted Activity)
Groundwater monitoring will be conducted approximately seven (7) weeks following each EAB injection
event, however, the groundwater monitoring schedule is subject to modification based on observations
made during each EAB injection event. Groundwater monitoring activities will continue to consist of the
following (also Ref. Attachment 7);
Following equilibration to atmospheric temperature and pressure, collect one round of groundwater
elevation measurements at 8 groundwater monitoring wells;
Perform low -flow groundwater sampling at 8 groundwater monitoring wells. A portable stainless
steel bladder pump or equivalent with a new section of polyethylene tubing will be used to sample
each groundwater monitoring well. Each well will be purged at a rate of 200-400 milliliters per
minute (mt./min) until stabilization parameters are met (i.e., ORP, pH, temperature, dissolved
oxygen, turbidity, and specific conductance). Samples to be collected for dissolved metals
concentrations will be field -filtered using a 0.45-micron in -line filter; and
Groundwater samples collected from each monitoring well will be analyzed for PX (8260B), total
organic carbon (TOC) (9060A), sulfate (504) (9056A), total kjeldahl nitrogen (TKN) (351 2), alkalinity
(5M 2320B-2011), and magnesium (6010C).

ATTACHMENT 7
Modified EAB Pilot Test Monitoring Plan
This monitoring plan will be conducted simultaneously and following each EAB injection event, and
during SART installation and replenishment/recharge events.
EAB Infection Event Real Time Monitoring
1. Groundwater Elevational Monitoring
Groundwater elevation monitoring will be performed during each EAB injection event to
evaluate if mounding is occurring. Groundwater elevations will be collected at least four times
each day during injection as follows:
• Pre -injection baseline groundwater elevation measurement
• Three additional times during injection
Groundwater elevation monitoring will be performed for the following wells:
• KMW-6, KMW-7, KMW-8, KMW-12 and KMW-13
2. Surface Monitoring
Monitoring for visual observations of solution surfacing "day -lighting" to the ground surface of
any injected amendment or groundwater will be performed. if day -lighting becomes an issue
during the injections, injection pressure(s) and/or flow rate will be reduced or ternporarily
ceased to immediately mitigate the surfacing liquid. Any liquids shall be contained by the
placement of liquid -impervious sand bags around the day -lighted materials, placing an inert,
chemically cornpatible absorbent material (sand, speedy dry, etc.) and the materials cleaned up
and disposed of in accordance with the MSDS sheets.
3. Field Parameter Monitoring
Monitor select wells for the following parameters on a monthly basis with the intent to capture
groundwater elevations following precipitation events, when feasible:
• pH, temperature, oxygen reduction potential, and specific conductivity
The following wells will be monitored for field parameters:
• KMW-6, KMW-7, KMW-8, KMW-12 and KMW-13
SART Monitoring & Replenishment/Recharge
As stated previously in the application, this pilot test modification involves slow release, via a SART, of
soluble sulfate and a nitrogen source to promote biodegradation of paraxylene (PX) in the residual PX
source zone and shallow groundwater. Subsidence of the SART will occur as the amendments dissolve
into groundwater. TRC will replenish/recharge the SART as needed. The anticipated SART
replenishment/recharge schedule is once every 6 months.

7. HANDLING AND STORAGE
Handling:
Storage:
The use of appropriate respiratory protection is advised when concentrations exceed
any established exposure limits (see Sections 2 & 8). Wash thoroughly after handling.
Wash contaminated clothing/shoes. Use food personal hygiene practices.
When possible store this material in cool, dry, well -ventilated areas to protect product
quality. Keep container(s) tightly closed Store only in approved containers, if
applicable. Keep away from any incompatible material (see Section 10). Protect
containers) against physical damage.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering
Controls:
Ill current ventilation practices are not adequate to maintain airborne concentrations
below the established exposure limits (see Section 2), additional ventilation or exhaust
systems may be required.
Personal Protective Equipment (PPE)
Respiratory:
A NIOSII approved air purifying respirator with a type 95 (R or P) particulate filter
may be used under conditions where airborne concentrations are expected to exceed
exposure limits (see Section 2). Protection provided by air purifying respirators is
limited (see manufacturer's respirator selection guide). Use a positive pressure air
supplied respirator if there is potential for uncontrolled release, exposure levels are not
known, or any other circumstances where air purifying respirators may not provide
adequate protection. A respiratory protection program that meets OSHA's 29 CFR
1910.134 and ANSI Z88.2 requirements must be followed if workplace conditions
warrant a respirator.

The Cape Fear River represents a hydraulic boundary for groundwater. There are no
known water intakes on the Cape Fear River within 1 mile of the Site, and no existing
production wells on the APEX Oil Terminal property.
Served by Public Water Supply: Yes. Cape Fear Public Utility Authority (CFPUA), City
of Wilmington, Water Service Area (Ref Attachment Se).
5. General description of the contaminants if present in the soil and/or groundwater at the
site.
Site remediation involves addressing concentrations of paraxylene (PX) in the residual
PX source zone and shallow groundwater via in-situ enhanced anaerobic bioremediation
(EAB). The highest PX concentration for the project remedial area is in the vicinity of
monitoring well KMW-6 (i.e., the residual PX source zone). Previous EAB pilot test
activities have indicated that in-situ EAB amendments remain proximal to the general
remediation area, and are currently permitted to consist of amending groundwater with a
soluble form of sulfate in the form of Epsom Salt.
6. Name, approximate distance, and likelihood of impact to the nearest body of surface
water to the site.
The Cape Fear River is located approximately 1,300 lnft west (downgradient) of the Sites
western property boundary. Groundwater concentrations of PX attenuate from the
highest concentration of 14,000 ug/1 (April 2017) at monitoring well KMW-6 to 57.1 ug/1
at AMW-3 located approximately 450 ft. west (downgradient) ofKMW-6 on the APEX
Oil Terminal property. Assuming Site specific sulfate utilization rates remain consistent
with those observed during previous EAB pilot test activities (June 2016 to January
20017), there is a low probability that groundwater amendments will reach AMW-3, and
subsequently the Cape Fear River.
7. Approximate distance to nearest residence(s) and workplace.
The Site is located in a heavily industrialized area. There are no residential areas
downgradient (west) of the Site. The APEX Oil Terminal is located directly west
(downgradient) of the Site. The closest residential area is located approximately 1,550
lnft to the east (upgradient).

Good morning,
Our records show that the Gw-is for the well were not submitted before. Hence, the status as active is not there.
It is possible to use those existing wells for this new permit even if they are not active in the system. Please resubmit
the amended NOI with a new site map showing the location of all wells.
Thank you,
Shristi

Good Morning Ms. Shrestha,
We are providing an update on Class V remediation well permit W10800455. We were able to complete two of the
three proposed wells in the proposed locations. Attached are the GW-1 forms for the two new wells. The attached
Forms are being submitted to DENR via mail. We experienced an access issue with placement of the third well that
would have placed the well too far from the remediation area to have a beneficial outcome. We did, however, locate
two existing wells that were previously registered for a Class V remediation program that was not implemented. The
registration forms for wells, 51-11 and S1-12 are slightly different than the current form but the information contained

registrations for SI-11 and SI-12 are active and that we can use these wells for the purpose of our EAB pilot
test. Alternately, please advise if the registrations of SI-11 and SI-12 have expired and r esubmittal of new GW-1 forms
for SI-11 and SI-12 is required.
Thank you for your time.

Subject: WI0800455 NOi Former FHR North Terminal
Thank you for submitting the Notice of Intent to Construct or Operate Injection Wells (NOi) for the above referenced
site.
Please remember to submit the following regarding this injection activity:
1) Well Construction Records (GW-1) and Abandonment Records (GW-30) when completed. Please provide copies of
the GW-ls and GW-30s if not already submitted (ori ginals go the address printed on the form). NOTE: Direct
push or Geoprobe wells are considered wells and require construction (GW-1) and abandonment forms (GW-
30). If well construction/abandonment information is the same for the wells, only one form needs to be
completed-just indicate total number of injection points in the Comments/Remarks section of form. These forms
can be found on our website at http:ljportal.ncdenr.org/web/wq/aps/gwpro/reporting-forms.
2) Injection Event Records (IER). All injections, including air and passive systems require an IER. The IER can be
modified for air sparge wells (e.g., air flow 'continuous' for date or rate of injection, etc.).
You can scan and send these forms directly to me at Shristi.shrestha @ncdenr.g ov or via regular mail to address
below. When submitting the above forms, you will need to enter the nine-digit alpha-numeric number on the form
(i.e., WI0XXXXXX) that has been assigned to the injection activity at this site. This notification has been given the
deemed permit number WI0800455. This number is also referenced in the subject line of this email. You may if you
wish, scan and send back as attachments in re p ly to this email, as it will already have the assigned deemed permit
number in the subject line .
Thank you for your cooperation.

Good morning,
Cur records show that the Gw-1s for the well were not submitted before. Hence, the status as active is not there.
It is possible to use those existing wells for this new permit even if they are not active in the system. Please resubmit
the amended NOI with a new site map showing the location of all wells.

Good Morning Ms. Shrestha,
We are providing an update on Class V remediation well permit WI0800455. We were able to complete two of the
three proposed wells in the proposed locations. Attached are the GW-1 farms for the two new wells. The attached
forms are being submitted to DENR via mail. We experienced an access issue with placement of the third well that
would have placed the well too far from the remediation area to have a beneficial outcome. We did, however, locate

Thank you for submitting the Notice of Intent to Construct or Operate Injection Wells (NOI) for the above referenced
site.
Please remember to submit the following regarding this injection activity:
1) Well Construction Records (GW-1) and Abandonment Records (GW-30) when completed. Please provide copies of
the GW-ls and GW-30s if not already submitted (originals go the address printed on the form). NOTE: Direct
push or Geoprobe wells are considered wells and require construction (GW-1) and abandonment forms (GW-
30). If well construction/abandonment information is the same for the wells, only one form needs to be
completed -just indicate total number of injection points in the Comments/Remarks section of form. These forms
can be found on our website at http://portal.ncdenr.org/web/wq/aps/gwpro/reporting-forms.
2) Injection Event Records (1ER). All injections, including air and passive systems require an IER. The iER can be
modified for air sparge wells (e.g., air flow `continuous' for date or rate of injection, etc.).
You can scan and send these forms directly to me at Shristi.shresthancdenr.p,ov or via regular mail to address
below. When submitting the above forms, you will need to enter the nine -digit alpha -numeric number on the form
(i.e., WIOXXXXXX) that has been assigned to the injection activity at this site. This notification has been given the

T. Description of Proposed Injection Activities
Purpose: Pilot test for in -situ remediation of dissolved para-xylene (PX) concentrations in shallow
groundwater.
Scope:
Perform up to two injection events. The initial, or primary event will be performed to evaluate
aquifer response. The secondary event will be performed based upon the results of the primary
event to confirm potential sulfate utilization and PX attenuation rate.
Two 4" injection wens will be installed to a depth of 10 feet below ground surface (bgs) and
screened from 6 feet to 10 feet bgs. Two existing 2" temporary well locations will be used as
injection points, each 6.5 feet deep bgs. Based upon an evaluation of remedial options, enhanced
anaerobic bioremediation (EAB) was selected as the most viable remedy for dissolved PX.
A soluble form of sulfate delivered to groundwater serves as an electron -acceptor and enhances
the natural anaerobic degradation of the hydrocarbon plume. Magnesium Sulfate (Epsom Salt), an
NCDEQ-approved injectant, was selected as the soluble sulfate source.
Construct three well headers consisting of a tight well seal cap and injection piping, and fit each
of the three wells with a header assembly.
Mixing and delivery of the groundwater amendment will be via tanker truck. Potable water is
required to dilute and mix the Epsom Salt (reagent) solution, and will be obtained from an
existing nearby potable water source capable of delivering water at a minimum of 100 gallons per
minute (gpm).
Daily quantities of required reagent solutions will be mixed with potable water in a 5,000 gallon
tanker truck. An injection manifold system will be used to monitor, control and route the reagent
solution during the injection operations. The injection manifold system and each well point will
have in -line pressure gauges and flow meters installed for safety, observation, and measurement
purposes. The pressure gauges will be monitored to prevent excessive back pressures and to
ensure the targeted injection pressures are maintained throughout the injections. Totalizing flow
meters will record the total amount of reagent solution injected into each injection well during the
primary injection event.
The post -primary injection groundwater sampling data will be reviewed and a determination will
be made if a secondary injection is required for the pilot test. ft is assumed that the secondary
injection event will be performed under the same conditions as the primary injection event.
During the injections, real time electronic water level elevation measurements via water level
meter will be recorded at 5 groundwater monitoring wells to evaluate any changes in water
elevations during injection activities. These measurements will be collected at least three times
per day with one round of baseline measurements performed for comparative purposes. The
results of the water level measurements will be used to further assess the effective radius of
influence and/or modify the on -going injection as needed based on field conditions. Should
instrument readings confirm significant groundwater mounding at the above referenced wells
(i.e., greater than 3 foot increase in groundwater elevation), and/or if it appears that groundwater
surfacing may be likely, injection flow rates will be reduced and/or injection ceased until the
groundwater levels stabilize to pre -injection levels.
Real time measurements of pH, temperature, oxygen reduction potential (ORP), and specific
conductivity via dedicated trolls or a Horiba water quality meter will be recorded at 5groundwater
monitoring wells to evaluate any changes in these parameters during EAB pilot test activities.
This data will be collected and recorded at least 3 times per day in addition to one round of
baseline measurements for comparative purposes.

Monitoring for visual observations ofreagent and groundwater surfacing (i.e., day-lighting) will
be performed. If day-lighting becomes an issue during the injections, injection pressure(s) and/or
flow rate will be reduced or temporarily ceased to immediately mitigate the surfacing liquid. Any
surfacing liquids will be contained by the placement of liquid-impervious sand bags around the
day-lighted materials, placing an inert, chemically compatible absorbent material (i.e., sand,
speedy dry, etc.), and the materials cleaned up and disposed in accordance with the MSDS sheets.
Rate: The reagent will be gravity fed or pumped (if necessary) through a manifold into the three
injection wells at an estimated injection flow rate of 3 to 5 gpm at pressures of approximately 5 to 15
pounds per square inch (psi). Sequencing of well amendments will be detennined in the field based
upon aquifer response.
Volume: In both the primary and secondary injection events, approximately 3,300 gallons of Epson
Salt solution will be injected in each 4" well, and 1,650 gallons in each 2" well . The solution will
consist of 10,000 pounds of Epson Salt and 10,000 gallons of potable mix water.
Duration: Each injection event is anticipated to take two 10-hour days . It is anticipated that the
secondary injection event, I required, will occur within four months following the primary injection
event.
Groundwater Monitoring: Groundwater monitoring will be conducted within 15 weeks following
each injection event. Groundwater monitoring activities will consist of the following:
Following equilibration to atmospheric temperature and pressure, collect one round of
groundwater elevation measurements at 8 groundwater monitoring wells.
Perfonn low-flow groundwater sampling at 8 groundwater monitoring wells. A portable stainless
steel bladder pump with a new section of polyethylene tubing will be used to sample each
groundwater monitoring well. Each well will be purged at a rate of 200-400 milliliters per minute
(mL/min) until stabilization parameters are met (i.e., ORP, pH, temperature, dissolved oxygen,
turbidity, and specific conductance). Samples to be collected for dissolved metals concentrations
will be field-filtered using a 0.45-micron in-line filter.
Groundwater samples collected from each monitoring well will be analyzed for PX (8260B), total
organic carbon (TOC) (9060A), sulfate (SO4) (9056A), total kjeldahl nitrogen (TKN) (351.2),
alkalinity (SM 2320B-2011), and magnesium (6010C).

MONITORING PLAN
Attachment 7
Injection Monitoring Plan
The following program will be implemented for primary and secondary injections (if secondary injection
is necessary).
Real Time Monitoring
Groundwater Elevations-Groundwater elevation monitoring will be performed in wells
proximal to the injection area to evaluate if mounding is occurring. Groundwater elevations will be
collected at least four times each day during injection as follows:
• Pre-injection baseline groundwater elevation measurement
• Three additional times during injection
Groundwater elevation monitoring will be performed for the following wells:
• KMW-6, KMW-7, KMW-8, KMW-12 and KMW-13
Field Parameter Monitoring -Monitor select wells for the following parameters with the
frequency of one baseline measurement and two additional measurements for each day of injection:
• pH, temperature, oxygen reduction potential, and specific conductivity
The following wells will be monitored for field parameters:
• KMW-6, KMW-7, KMW-8, KMW-12 and KMW-13
Surface Monitoring -Monitoring for visual observations of solution surfacing "day-lighting" to
the ground surface of any injected chemical solution or groundwater will be performed. If day-lighting
becomes an issue during the injections, injection pressure(s) and/or flow rate will be reduced or
temporarily ceased to immediately mitigate the surfacing liquid. Any liquids shall be contained by the
placement of liquid-impervious sand bags around the day-lighted materials, placing an inert, chemically
compatible absorbent material (sand, speedy dry, etc.) and the materials cleaned up and disposed of in
accordance with the MSDS sheets .
Breathing Zone Monitoring -Field representatives will conduct periodic field screening of the
breathing zone within the injection work zone. Field monitoring will consist of field screening for
organic vapor concentrations using a PIO.
Groundwater Sampling
Groundwater sampling will be performed 10 weeks following each injection event. Groundwater
samples will be collected at monitoring wells KMW-6, KMW-7, KMW-8, KMW-9R, KMW-12, KMW-13,
AMW-2 and AMW-3. Analytical parameters will include PX, Sulfate, Total Kjeldahl Nitrogen, TOC,
Alkalinity, and magnesium.
