Mr. Murray:
Antea USA of North Carolina Inc. (Antea USA of NC) is proposing to complete in -situ injection activities to address
dissolved phase hydrocarbons in groundwater at the above referenced site. Below is a discussion of our project
goals and proposed remedial strategy. Also attached is the remedial project design completed by Regenesis
(Attachment 1).
GOALS
Antea USA of NC understands that site closure can be achieved by meeting each of the following goals:
Reduce concentrations in monitoring wells MW-21, MW-47, and MW-48 to below Gross Contamination
Levels (GCLs)
Request reduced site ranking and incident closure through existing Notice of Residual Petroleum
PROPOSED INJECTION AND GROUNDWATER MONITORING ACTIVITIES
Antea USA of NC is proposing to complete three separate injections to achieve the project goals. The first two
injections events will include the application of Regen00 (RegenOx). RegenOx consists of an oxidant and a
catalyst that when combined will generate highly oxidizing free radicals that will destroy petroleum hydrocarbons.
The proposed remedial strategy will include direct applications of RegenOx into three on -site monitoring wells
(MW-21, MW-47, and MW-48). Direct injection into each of the wells is proposed due to the presence of existing
piping racks and underground utilities (see well photos in Attachment 11). After each injection event the wells will
be flushed with clean water to remove the injection material from the well.
The third injection will include the application of PetroFix° (PetroFix) paired with anaerobic electron acceptors.
PetroFix is an activated carbon remedial fluid that is milled to a diameter of 1-2 micrometers. The PetroFix and
electron acceptor solutions will be directly applied into the same three on -site monitoring wells (MW-21, MW-47,
and MW-48) and at the completion, will be flushed with a calcium chloride solution to remove the injection
material from the well and accelerate clarification of aquifer water.

Proposed Solution
We are proposing the use of RegenOx and PetroFix Remedial Fluid to remediate dissolved phase hydrocarbons at your project
site. The RegenOx should be applied before the PetroFix, with 2-4 weeks between RegenOx events and at least 1 month
between RegenOx and PetroFix. The plan provided by Antea Group specifies direct injection into the target monitoring wells.
Also included is a monitoring well flushing plan with calcium chloride to remove PetroFix from the monitoring well.
Project Goals
e Direct injections of remedial agents into MW-21, MW-43, and MW-47
e Achieve the gross contamination levels (GCLs) at both wells
Technologies Proposed
e PetroFix
e RegenOxS
Design Assumptions
e Well screens are not clogged and can accept large volumes of water.
e No free product in the wells or surrounding treatment areas.
e RRS will be able to flush each monitoring well with calcium chloride after injections.
e Wells should not be sampled if black water is present.
e Impacted areas are fairly localized to the monitoring well.

Technical Approach
RegenOx is an advanced chemical oxidation technology that destroys contaminants through powerful, yet controlled
chemical reactions. This product maximizes in -situ performance while using a solid alkaline oxidant that employs a sodium
percarbonate complex with a multi -part catalytic formula. RegenOx directly oxidizes contaminants while its unique
catalytic component generates a range of highly oxidizing free radicals that rapidly and effectively destroy a range of
target contaminants including both petroleum hydrocarbons and chlorinated compounds.
PetroFix is a unique activated carbon remedial fluid (carbon milled to a diameter of 1 to 2 micrometers) paired with
soluble, anaerobic electron acceptors designed to remediate dissolved hydrocarbons. This allows the product to be
injected as a fluid using low pressure. PetroFix is commonly used for source and plume treatment, excavation polishing,
and barrier applications. PetroFix features:
• Provides rapid and sustained results allowing for faster and more certain site closure
• Dual -technology approach relies on both carbon sorption and anaerobic biodegradation
• Low-pressure "flooding" vs high pressure "fracturing" improves distribution and reduces surfacing
• Safe to handle because is non -hazardous and shipped as a liquid (no fugitive carbon dust)
• Mitigates hydrocarbon back diffusion which is a cause of concentration rebound
PetroFix is typically self -applied and is supported by a large library of application instruction, technical bulletin, and
videos (www.petrofix.com/resources). Based on our experience at hundreds of sites we have developed
recommendations listed in a hyperlinked planning document included in the following sections. Below are links for

Statement of Qualifications
RRS provides turn -key remediation planning, design, and application services. RRS field scientists are college degreed
professionals that understand an accurate remediation design using the proper chemistry and appropriate dosage can fail
to show good performance if management of the injection program is not performed in a manner to validate the intended
treatment rationale and design. They have the unique background and experience to understand the significance of
modifications made in the field. No one has more professional experience handling and applying in -situ remediation
products than RRS personnel. The direct management of the injection program through RRS will optimize the design and
ultimately the overall performance of the injection program.
For years, RRS has been offering industrial leading application services combined with excellence in field activity
management. Our success is achieved after meeting cleanup objectives established by the environmental engineering
firms who contract our services. To produce this outcome, we field project teams with the experience, discipline and
dedication to work hand -in -hand with our client to address the unique requirements of each project site. Technical insight
and timely, direct and honest communication are hallmarks of RRS. Our reputation for meeting or exceeding clients'
objectives and those of environmental regulators has been proven in project successes throughout North America.

RRS Scope of Services
RRS will work under the direction ofAntea Group to
implement the field work associated with the application of
the selected remediation technologies. Responsibilities for
the implementation of this scope of work will be shared
between RRS and Antea Group. Responsibilities for each are
outlined in this section and further under the Assumptions/
Qualification section.
At the beginning of each day a safety tailgate meeting will
be conducted and an overview of the procedures,
responsibilities and goals for the day will be discussed. RRS
will be equipped with injection well heads.
The remediation technologies will be mixed in an injection
trailer (Figure 2) with water in batches at the designated
solution percentage and kept in constant suspension
throughout the injection application. Pressures, flow rates
and total volumewill be monitored and digitally documented
for each injection interval. Multiple injection points may be
injected into simultaneously to increase efficiencies on -site.
The injection points and surrounding areaswill be monitored
for any signs of surfacing and a spill response kit will be on
standby.

During the application, real-time information will be
collected and analyzed to help verify design assumptions and
subsurface reagent distribution. Depending on the primary
product applied, data collected and analyzed may consist of
groundwater quality parameters (i.e., pH, conductivity, DO,
ORP, etc.), depth to water measurements, visual indicators
through groundwater or soil samples, and in -field injection
concentration test kits. This information is typically collected
during the application when within 10 feet of an
appropriately screened monitoring well. Based on the
information collected, the project team may choose to
modify the remediation design to further optimize the
injection application. This includes modification to injection
concentrations, volume per vertical foot, injection intervals,
etc.
Once the injection event is completed, RRS will demobilize
all equipment and personnel off -site. A detailed injection
summary report which includes injection point data (interval
depths, injection pressure/flow rates, reagent volume, time
elapsed and if surfacing occurred), field observations and any
other noteworthy information will be generated and made
available to Antea Group.

Project Responsibilities
RRS will:
• Provide and ship the specified quantities of the remediation reagents to the site address provided by Antea Group. RRS
shipping estimates assume all products will be shipped to the site at the same time.
Coordinate with Antea Group prior to any shipment of product. Alternative shipping locations or phases could lead to an
increase in freight costs.
Mobilize a 40-hour HAZWOPER certified crew experienced in the proper application of REGENESIS remediation
technologies.
Provide calcium chloride parking agent and flush all three wells at the end of the PetroFix application event.
Antea Group will:
Coordinate project schedule and reagent order with REGENESIS to ensure adequate shipping and mobilization time.
Coordinate site access with property owner to coincide with project schedule and identify a secure product staging area.
Take delivery of the remediation chemistry for all three events prior to RRS mobilization and stage inside a secure storage
location where the material will not be affected by inclement weather. Antea group will provide safe and secure chemical
storage between events. During injection activities, Antea Group will locate product container within 10 feet of the RRS
injection trailer
RRS can receive, store, and transport the RegenOx for this project at the price listed below.
Provide further means to maneuver product within proximity of the RRS injection trailer.
Provide a water source (eg. Fire Hydrant).
Be responsible for disposal or recycling of totes, drums, pails and pallets. All nonhazardous refuse will be collected and placed
in a Antea Group -provided on -site refuse container for disposal. RRS will collect project related refuse and empty treatment
chemistry containers daily to keep the site clean.
- Will provide 55-gallon DOT drums to containerize surfaced material.
Be responsible for transportation and disposal of any contaminated waste generated on -site during injection activities.
Antea Group will provide field water quality meter similar to a YSI 556 with a down -hole sensor, a water level meter, bailers
and a technician while on -site for injection activities to assist RRS in assessing groundwater from monitoring wells.

Services Assumptions and Qualifications
In generating this proposal, REGENESIS relied upon professional judgment and site -specific information provided by
others. Using this information as input, we performed calculations based upon known chemical and geologic
relationships to generate an estimate of the mass of product and subsurface placement required to affect remediation
of the site. The attached design summary tables specify the assumptions used in preparation for this technical design.
We request that these modeling input assumptions be verified by your firm prior to application of the product. Other
assumptions and qualifications related to this proposal are as follows:
- The product and services cost outlined will be valid
for 60 days from date of proposal. If beyond 60 days,
REGENESIS reserves the right to update cost.
The freight charges included for product delivery
above are estimated at the time of proposal
generation. Actual freight charges are neither set nor
guaranteed by REGENESIS and are calculated when
the product order is placed. This price may vary from
what is estimated above. Actual freight charges for
product delivery will be invoiced.
Freight delivery time frames cannot be guaranteed
and RRS will not be responsible for any delays or any
resulting increase in cost associated with those
delays.
If applicable, sales tax charges for product, freight,
and services are considered estimated at the time of
proposal submittal. The appropriate sales tax
category (i.e., product, freight, and services) and
actual sales tax rate is finalized at the time of invoice
and may change from date of proposal submittal.
RRS will have access to the site for equipment
operation and secure storage of materials and
equipment throughout the duration of the project. All
access to each work area location will be clear and
free of obstructions. RRS also assumes the injection
trailer will be staged within 80 feet of the furthest
injection point location.
Antea Group is responsible for securing any permits
prior to mobilizing to the site.
Antea Group is responsible for all soil, air, and
groundwater sampling and analysis.
RRS will not transport unused material back to their
shop.
RRS will store material for a maximum of 2 months.
- For safety reasons, access to the treatment area will
be limited to RRS and Antea Group personnel.
The remediation design and injection procedures
contain the necessary precautions to minimize the
likelihood of surfacing of the treatment chemistry.
RRS will monitor treatment chemistry application
flow rates and pressures as well as observe for signs
of reagent surfacing around active injection areas. If
surfacing is detected, RRS will stop or slow down
injection activities at that location to stop additional
surfacing and remove/vacuum up recoverable
surfaced fluid. RRS is not be responsible for
treatment chemistry infiltration into undesired
locations beyond our visible control.
RRS personnel will have access to the site for work up
to 12 hours per day Monday through Friday (daylight
hours). However, the standard workday does not
exceed 10 hours with travel time Monday through
Friday. A 10-hour workday does not mean 10 hours
on -site and/or injection pumping. Additional charges
may apply for Saturday and/or Sunday work
schedules.
Pricing and work schedule assume union labor and
prevailing wages (Davis -Bacon) are not required.
All traffic control requirements, if necessary, will be
provided by Antea Group.
Site conditions can change over time and should be
monitored post injection. REGENESIS is not
responsible for changing site conditions after
completing the scope of work and demobilizing from
the site. This includes but is not limited to changes
related to well fittings and vaults, surface restoration,
well conditions, and on -site utilities.

Health and Safety Plan
REGENESIS is committed to providing a safe and healthy
working environment for all employees, Antea Groups and
contractors on -site. Prior to mobilization RRS will develop a
site -specific Health and Safety Plan (HASP) and designate an
on -site safety officer. All personnel on -site are required to
participate in daily safety tailgate meetings with the goal of
proactively identifying potential hazards and mitigating risks
to the full extent possible.
In addition to the hours of rigorous safety training courses
all personnel are required to complete, REGENESIS also
incorporates a behavior -based safety program by utilizing
our DoneSafe mobile application (app) interface on every
site. This app encourages our personnel to actively search
for potential on -site risks and document mitigation actions
taken. The effectiveness of our safety program can be seen in
our industry leading EMR ratings listed in Table 3.

RRS safety tailgate meetings and HASP will
include the following:
• Site map with entrance and exit points and best
possible muster points depending on conditions.
• List of personnel and contact information for
employees on -site and supporting the project.
• Route to the nearest occupational treatment
facility and hospital along with contact
information.
• Job Hazard Analysis (JHA) detailing each job task
on -site with its potential hazards and best

Well Application Planning Document
When storing the PetroFix material prior to application, it is important to prevent it from freezing or from prolonged
exposure to temperatures above 95°F.
Storage requirements for freezing or hot weather
Safety Data Sheets (SDS)
The key to a successful well application is to have properly screened wells where the screen is confined across your
treatment zones only. We recommend you use a water -tight injection attachment to the top of your well and apply
PetroFix under low pressure (commonly 20-30 psi). Optimally, you can construct your monitoring wells with a
male NPT thread so receive a female threaded injection hose adapter. If you are using existing injection wells you
can use ratchet straps that prevents gluing any attachments fittings to a well. Please consult with your injection
contractor for their recommended method to inject into your monitoring well (s). Flushing by gravity feed into wells
is not recommended. When complete some practitioners opt for a clearwater post -injection flush at the end of their
injection activities. If your site has a high number of wells we recommend that you install a single well and do a pilot
injection prior to full-scale implementation to verify the ability to inject PetroFix at the specified volumes.

Please note, PetroFix takes up to a few months to fully attach to soils. If PetroFix is >100 mg/L in concentration
(difficult to see through a 40 ml VOA), it is recommended groundwater not be sampled. Each PetroFix shipment
comes with one (1) a colorimetric field test kit taped to the top of a tote or drum to help assess field concentrations.
For additional information, please review the "Groundwater Sampling Guidance Document".

Technical Protective Measures
Storage: Oxidizer. Store in a cool, well ventilated area away from
all sources of ignition and out of the direct sunlight. Store
in a dry location away from heat and in temperatures less
than 40 'C.
Keep away from incompatible materials and keep lids
tightly closed. Do not store in improperly labeled
containers.
Protect from moisture. Do not store near combustible
materials. Keep containers well sealed.
Store separately from reducing materials. Avoid
contamination which may lead to decomposition.
Handling: Avoid contact with eyes, skin and clothing. Use with
adequate ventilation.
Do not swallow. Avoid breathing vapors, mists or dust.
Do not eat, drink or smoke in the work area.
Label containers and keep them tightly closed when not in
use.
Wash hands thoroughly after handling.
Personal Protective Equipment (PPE)
Engineering Controls: General room ventilation is required if used indoors. Local
exhaust ventilation, process enclosures or other
engineering controls may be needed to maintain airborne
levels below recommended exposure limits. Avoid
creating dust or mists. Maintain adequate ventilation at all
times. Do not use in confined areas. Keep levels below
recommended exposure limits. To determine actual
exposure limits, monitoring should be performed on a
routine basis.
Respiratory Protection: For many conditions, no respiratory protection is
necessary; however, in dusty or unknown conditions or
when exposures exceed limit values a NIOSH approved
respirator should be used.
