Dear Bill:

1.0 Introduction

Hart & Hickman, PC (H&H) has prepared this Vapor Intrusion Mitigation Plan Addendum
(VIMP Addendum) on behalf of Embrey Partners, LLC and its single purpose entity Scaleybark
CLT, LLC (Prospective Developer or PD) for the Simpson’s Texaco Service Brownfields
property (Brownfields Project No. 25063-21-060) located at 4001 South Boulevard, at the
intersection of South Boulevard and Scaleybark Road in Charlotte, Mecklenburg County, North
Carolina (Site or subject Site). The proposed Site redevelopment includes construction of an
approximately 28,100 square foot (sq ft) high-density multifamily residential apartment complex
with amenity spaces and a multi-level parking garage. A Site Location Map is provided as
Figure 1.

To address potential vapor intrusion concerns for the building, H&H prepared a VIMP and
revisions to the VIMP based on DEQ comments. In a letter dated October 21, 2022, the DEQ
Brownfields Program provided approval of the revised VIMP dated August 26, 2022.

The VIMP included installation of a vapor intrusion mitigation system (VIMS) designed to
minimize potential vapor intrusion into the Site building using passive sub-slab venting. The
passive sub-slab venting system includes a network of horizontal piping installed beneath the
slab of the building with passive turbine ventilators installed on the discharge end of the vertical
riser exhaust piping above the building roofline to further promote air exhaust from the risers. In
addition to the sub-slab depressurization system, the VIMS includes Raven Industries
VaporBlock Plus 20 (VBP20) vapor barrier installed under the ground floor of the residential
apartment building.

The VIMP specified installation of vapor barrier beneath the base slab and along the exterior of
the vertical sidewalls of the elevator pit. However, the elevator pits at two elevator locations,
Elevators E100 and E300, were poured without installation of the vapor barrier along the base
and sides of the pit. Based on conversations with the general contractor, it is our understanding
that the specified vapor barrier was not installed along the exterior walls and base of the elevator
pit, however the pit was lined along the exterior with a waterproofing barrier. Because the vapor
barrier specified in the VIMP was not installed, the PD is proposing to install Retro-Coat™
vapor barrier system to further protect against potential vapor intrusion in the elevator pit. For
consistency in the VIMS installation, the PD has proposed to install the Retro-Coat vapor barrier
system in all four elevators (E100 through E400). The locations of the elevator pits are shown
on the design sheet (VM-ADD) in Appendix A.

2.0 Proposed VIMS Activities
The proposed VIMS activities include application of Retro-Coat in the elevator pits, as further
described below. The locations of the elevator pits and details showing the installation
modification is included on Sheet VM-ADD in Attachment A. Retro-Coat specifications and
installation instructions are included in Attachment B.

Retro-Coat Application in Elevator Pit
Retro-Coat is a volatile organic compound rated engineered vapor barrier, similar in function to
MonoShield®, which includes a Retro-Coat Primer layer and the final Retro-Coat layer.
According to manufacturer installation instructions, the Retro-Coat PRIMER should be installed
at a thickness of approximately 6-mil and allowed to dry prior to application of the Retro-Coat
layer. The Retro-Coat layer is a mixture of Retro-Coat “A”, a modified epoxy, and Retro-Coat
“B”, a blend of hardeners. Retro-Coat “A” and Retro-Coat “B” should be mixed in the field in
accordance with the installation instructions and following completion of mixing, the Retro-Coat
is applied over the Retro-Coat PRIMER at a minimum thickness of 20-mil. The concrete surface
on the elevator pit interior will be properly prepared in accordance with the manufacturer
instructions prior to the application of the Retro-Coat PRIMER and Retro-Coat.

As discussed above, the waterproofing for the elevator pit was installed to the exterior of the
elevator pit. Based on information provided by the construction contractor, the installed
waterproofing system is the Polyguard Waterproofing System. Product specifications for the
installed waterproofing system are included in Attachment C.

Inspections
The Retro-Coat barrier system shall be installed by a certified Retro-Coat Applicator in
accordance with manufacturer recommendations and specifications. For quality assurance and
quality control (QA/QC) purposes, periodic inspections will be conducted during installation of
the Retro-Coat™ vapor barrier. The inspections will be performed by, or under the direction of,
a North Carolina licensed professional engineer. DEQ will be notified 48 hours prior to the start
of the Retro-Coat installation activities.

Chemical Resistance

Vapor Intrusion Coating System for Existing Structures
Product Description
The Retro-Coat™ (patent pending) Vapor Intrusion
Coating System is a complete product line that consists of
chemically resistant materials to properly protect existing
structures from the threat of contaminant vapor intrusion
without the need for additional concrete protection.
Developed by the R&D team of Land Science
Technologies™, the Retro-Coat system has been subjected
to rigorous testing procedures to prove its ability to combat
the most aggressive chemical vapors. The main component
of the Retro-Coat system is the Retro-Coat coating which is
a two part, odorless, no VOC, 100% solids coating.

Retro-Coat finishes to a high gloss, easy-to-clean surface
that is impervious to vapor and moisture transmission.
Available in a variety of colors, Retro-Coat can be applied
on damp as well as dry concrete, concrete masonry units,
tile, brick and metal. For enhanced slip resistance, a
suitable aggregate can be added. In addition, other
additives or materials can be utilized to achieve a desired
performance or aesthetic look.

Typical Application
Retro-Coat is suitable as a barrier to block contaminated
vapors from entering existing structures. Particular uses
include coating the horizontal surfaces of existing structures
where contamination under, or adjacent to, a structure can
potentially migrate inside the structure and create a vapor
encroachment condition. This condition is most commonly
found when the existing structure was operated as a dry
cleaner, gas station, manufacturing facility or located in
close proximity to any structure where carcinogenic
chemicals were utilized.
A typical application consists of a minimum 20 mil thick
system; consisting of two 10 mil coats of Retro-Coat at 160
SF/gallon per coat and is recommended along with a 6 mil
coat of Retro-Coat PRIMER. The typical 20 mil application
can withstand forklift traffic, other machinery and even act
as secondary containment. However, if Retro-Coat may be
exposed to more harsh conditions over a longer period of
time, thicker applications ranging from 60 mil to ¼ -inch may
be more suitable.
In either application, Retro-Coat is a traffic bearing surface
and does not need a protective course placed over it.

Retro-Coat Advantages

• Our R&D team developed all of the
Retro-Coat system components
specifically for vapor intrusion
protection in existing structures

• Retro-Coat is resistant to both TCE and
PCE, the vast majority of coatings
cringe at such aggressive chemicals

• Retro-Coat is a wearing surface,
meaning no additional concrete
protection is necessary

• No odor and fast cure time reduce
building downtime

• Carpet, tile, linoleum or other floor
coverings can be applied directly over
Retro-Coat, if desired

• Eliminates the need to remove the
existing slab and when combined with
in-situ treatment, lowers overall
remediation cost

• Retro-Coat can increase the
performance of an existing active sub-
slab depressurization system

• Retro-Coat can aid in the retiring of
existing active systems

• Available and installed by Land
Science Technologies certified
contractors

Installation
Particular care must be taken to follow those instructions precisely to assure proper installation. These instructions
pertain to a standard 20 mil application; please contact us if the desired application is different.

1. New concrete should be allowed to cure a minimum of 28 days and/or be checked with a rubber mat or plastic sheet to
ensure adequate curing time has occurred.
2. All surfaces to be covered should be power washed, shot blasted, acid etched, scarified or sanded to present a clean,
sound substrate to which to bond to. The prepared surface should have a ph of 7.
3. Any bugholes and cracks wider than 1/8” should be filled with Retro-Coat PREP and allowed to dry before coating. More
severely damaged concrete or other special conditions will require the proper Retro-Coat product.
4. When installing the standard 20 mil application of Retro-Coat, apply a 6 mil coat of Retro-Coat PRIMER and
allow to dry prior to applying the initial coat of Retro-Coat. Priming may not be necessary when Retro-Coat
is applied to a thickness greater than 20 mils. On new concrete or old concrete with an open porosity and on
wood surfaces apply Retro-Coat PRIMER and allow to dry.
5. The two Retro-Coat ingredients should be mixed in the prescribed ratios, using a low speed “jiffy-style” mixer,
(maximum 750 rpm). Mix Part A for about 1 minute then, add Part B and mix until uniform in color and consistency (at
least one additional minute.)
6. Do not mix less than the prescribed amount of any ingredient or add any solvent to the mix.
7. Apply the mixed Retro-Coat material with a short nap roller, a squeegee or a brush. Apply
approximately 160 SF per gallon per coat to achieve 10 mils of coating.
8. Apply a second coat while the first coat is still tacky if using spike shoes or dry enough to walk on, but before 7
hours at 75oF. If the first coat has set and is no longer tacky then the first coat should be sanded before
recoating.
9. A suitable aggregate may be broadcast onto the surface after backrolling to provide more anti-slip profile to the finished
surface. It is advisable to test various types and sizes of aggregate to achieve the desired finished profile.

Product Specification
The specified area shall receive an application of Retro-Coat as manufactured by Land Science Technologies, San
Clemente, California. The material shall be installed by precisely following the manufacturer’s published
recommendations pertaining to surface preparation, mixing and application. The material shall be a low odor, two
part, solvent free 100% solids, high gloss flexibilized system with good resilience to resist thermal and
mechanical shock. It should be able to be roller applied at a minimum of 10 mils thickness per coat on vertical
surfaces without sagging (at ambient conditions). The system must adhere to damp as well as dry concrete, wood,
metal tile, terrazzo and sound existing epoxy and urethane coatings. It shall have tensile elongation of at least 6.0%
when tested under ASTM-638. Its bond strength to quarry tile shall exceed 1000 psi when tested with an
Elcometer pull test. Its hardness shall not exceed 83, as measured on the Shore D scale. The system shall be
unaffected by oils and greases and shall withstand chemical attack for at least 72 hours against 98% sulfuric,
50% hydrofluoric acid, glacial acetic acid and acrylonitrile.

2 © 2012 Land Science Technologies
Part 2 – Application 2.1 Surface Preparation A. All existing surfaces that will be covered with the systems specified herein should be mechanically ground, shot blasted or sand blasted to yield a minimum 60 grit surface texture. All loosely adhered coatings will be removed. Any grease and other contaminants found on the concrete must also be removed. B. All open cracks 1/2” and greater should be v-notched to a 3/4” width by 1/2” depth and cleaned of any debris. Such cracks should be filled with Retro-Coat Gel and struck off flush with the surrounding surface.
C. Cut back and/or remove any expansion joint backing or filler strips to a minimum of 1 ½” deep. Insert disposable filler in the joints to prevent filling with the overlayment materials and to allow for accurate location of final saw cuts in the overlayment. 2.2 Material Application A. Retro-Coat CAULK 1. Apply Retro-Coat CAULK around the base of all pipe penetrations making sure to fill any gap between the
penetration and concrete slab 2. Apply Retro-Coat CAULK to the joint created between horizontal and vertical transitions. The caulking material should be applied and pressed into the joint filling any gaps that might be present.
B. Retro-Coat PRIMER 1. Apply Retro-Coat PRIMER to all areas at a thickness of 6 mil and allow to dry tack free. In areas where the concrete surface is in need of slight repair or needs to be leveled, a slurry form of Retro-Coat PRIMER
called Retro-Coat PRIMER-S can be applied with a flat squeegee. Retro-Coat PRIMER-S is self priming and does not need to be primed again. C. Retro-Coat 1. Mix Retro-Coat, Part A with a low-speed (<750 rpm) jiffy-style mixer for about 30 seconds, or until uniform in color, then mix in Retro-Coat Coating, Part B for another 30-60 seconds. 2. Dump contents onto floor in a ribbon pattern, squeegee, and then back roll at a coverage rate of 160 SF/gallon to achieve a film thickness of 10 mils.
3. Apply second coat 10 mil coat to achieve a total thickness of 20 mils. Repeat as necessary to achieve specified thickness. 4. If a flooring material will be placed over Retro-Coat after it is applied, or appearance is not a priority, (1) 20
mil coat can be applied. 2.3 Protection of Finished Work A. Prohibit foot traffic on floor for 24 hours after laying (at 70ºF). At 50ºF,this time should be extended to 48 hours. B. Rinse off any chemicals that may come in contact within 7 days of installation with the freshly laid floor immediately. 2.4 Cleanup
A. Properly dispose of all unused and waste materials. B. Tools can be washed in warm, soapy water when wet, but after drying, can only be cleaned by grinding or with a paint stripper. C. Unused resin can be set off with proper amount of hardener and disposed of in regular trash bins.

Part 3 – Quality Control
3.1 Warranty A. Installer shall provide a one year warranty against delamination, chemical attack and normal wear and tear. B. Manufacturer will provide a one year material warranty. 3.2 Quality Control A. Installer shall use a notched squeegee to apply Retro-Coat to the specified mil thickness and calculations shall be done to determine if the correct amount of material has been applied. Retro-Coat contains 100% solids at the time of application; therefore no material shrinkage will occur during the curing process. One gallon will cover 80 square feet. B. A wet mil film gauge can be used to spot check the Retro-Coat thickness to make certain the minimum 20 mil thickness has been applied, though some discretion should be used because high points or low points on the
underlying surface can adversely affect the thickness measurements. 3.3 Floor Care A. The standard smooth surface of Retro-Coat should be cleaned on a regular basis by damp mopping the floor with conventional commercial cleaners. It is important to first remove any grease or oils by a suitable cleaner, preferably a citrus based cleaner. Rinse with clear water to help eliminate film buildup and then allow to dry. Never use abrasive powder cleaners like Ajax or Comet as they tend to scratch the floor. B. Additional steps can also be taken to prolong the look and life of a seamless floor:
1. Protect the floor during transference of heavy equipment 2. Educate the drivers inside the building the importance of avoiding “jack-rabbit” starts and stops, as well as keeping the metal forks lifted
3. Regular cleaning should take place as to not allow the buildup of abrasive material, such as sand or dirt, on the coating 4. Eliminate all metal wheels
5. Change over to light-colored polyurethane wheels 6. Do not slide heavy metal totes, drums or bins across the floor
7. Immediately hose down chemical spills, especially on newly laid floors.

4.0 FIRST-AID MEASURES 4.1 Description of necessary first-aid measures:
Eye Contact: Immediately flush eyes with large amounts of water or normal saline for at least 30 minutes. Hold eyelids apart while flushing to rinse entire surface of eye and lids with water. Then remove contact lenses, if easily removable, and continue eye irrigation for not less than 15 minutes. Get medical attention if irritation develops. Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Call a physician if irritation persists. Wash clothing before reuse. Inhalation: Remove victim to fresh air if effects occur. If not breathing, give artificial respiration. Get immediate medical attention. Asthmatic-type symptoms may develop and may be immediate or delayed up to several hours. Ingestion: Do not induce vomiting. If patient is conscious and can swallow, give two cups of water or milk (16 oz.). Get immediate medical attention. Never give anything by mouth to an unconscious or convulsing person. 4.2 Most Important symptoms/effects, acute and delayed:
Signs and Symptoms: Irritation as noted above. Skin sensitization (allergy) may be evidenced by blisters, redness,
or rashes, especially hives. Aggravated Medical Conditions: Preexisting skin and eye disorders may be aggravated by exposure to this
product. Preexisting skin and lung allergies may increase the chance of developing increased allergy symptoms from exposure to this product. Other Health Effects: Based on animal studies, repeated exposure to components of this product may cause damage to respiratory systems. Reports have associated repeated and prolonged occupational exposure to solvents with
permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling vapors may be harmful or fatal. 4.3 Indication of immediate medical attention and special treatment needed, if necessary:
Note to Physician:
Eyes: Stain for evidence of corneal injury. If cornea is burned, instill antibiotic/steroid preparation frequently. Workplace vapors could produce reversible corneal epithelial edema impairing vision. Skin: This product is a known skin sensitizer. Treat symptomatically as for contact dermatitis or thermal burn. Ingestion: Treat symptomatically. There is no specific antidote. Inducing vomiting is contraindicated because of the irritating nature of the product. Inhalation: This product is a known pulmonary sensitizer. Treatment is essentially symptomatic. An individual having a dermal or pulmonary sensitization reaction to this material must be removed from any further exposure to any isocyanate. Contact a Poison Control Center for additional treatment information. Health studies have shown that many
petroleum hydrocarbons pose potential human health risks, which vary from person to person. As a precaution, exposure to liquids, vapors, mists, or fumes should be minimized.
5.0 FIRE-FIGHTING MEASURES 5.1 Suitable extinguishing media: Use foam, dry chemical, water spray, or CO2.
5.2 Specific hazards arising from the chemical: Flash Point is >200°F. Closed containers may explode when exposed
to extreme heat or burst when contaminated with water (CO2 evolved).
5.3 Special protective actions for fire-fighters: Full emergency equipment with self-contained breathing apparatus and
full protective clothing should be worn by firefighters. During a fire, HDI vapors and other irritating, highly toxic
gases may be generated by thermal decomposition. Use water spray to cool fire-exposed surfaces and to protect
personnel. Try to cover liquid spills with foam. Solvent vapors are heavier than air and may travel a considerable
distance where they may linger and/or find an ignition source and flash back.

6.0 ACCIDENTAL RELEASE MEASURES 6.1 Personal precautions, protective equipment and emergency procedures:
Evacuate nonessential personnel. Ventilate the area. Avoid breathing vapor. Use self-contained breathing apparatus or supplied air for large spills or confined areas. 6.2 Methods and materials for containment and clean up: Contain spill if possible. Prevent entry into sewers and
waterways. Cover spill with sawdust, vermiculite, Fuller’s earth, or other absorbent material. Pour decontamination
solution over spill area and allow reacting for at least 10 minutes. Collect material in open containers and add further
amounts of decontamination solution. Remove containers to a safe place, cover loosely, and allow to stand for 24 to
48 hours. Wash down spill area with decontamination solutions.
Decontamination Solutions: 1. nonionic surfactant Union carbide’s Tergitol TMN-10 (20%) and water (80%) 2. concentrated ammonia (3-8%), detergent (2%), and water (90-95%). Dispose of in accordance with federal, state, and local regulations.

11.0 TOXICOLOGICAL INFORMATION 11.1 Likely routes of exposure: N/A
11.2 Symptoms related to the physical, chemical and toxicological characteristics:
Eye Contact: Irritating and will injure eye tissue if not removed promptly. Prolonged vapor contact may cause conjunctivitis. Skin Contact: Isocyanates react with skin protein and moisture and can cause severe irritation. Has been known to cause allergic skin reaction in humans. Prolonged contact may cause blisters. Cured material is difficult to remove. Inhalation: High vapor concentrations are irritating to the eyes and respiratory tract causing runny nose, sore throat, coughing, chest discomfort, shortness of breath, and reduced lung function (breathing obstruction). The solvent vapors are anesthetic, cause headaches and dizziness and may have other central nervous system effects, including death. As a result of previous repeated overexposures or a single large dose, certain individuals will develop isocyanate sensitization (chemical asthma), which will cause them to react to a later exposure to isocyanate at levels well below the TLV. Sensitization may be either temporary or permanent. Ingestion: Can result in irritation and possible corrosive action in the mouth, stomach tissue, and digestive tract. Vomiting may cause aspiration of the solvent resulting in chemical pneumonitis. 11.3 Delayed and immediate effects and also chronic effects from short and long term exposure: N/A

Retro-Coat™ Floor Care Instructions
Retro-Coat™ provides the highest level of chemical resistance and vapor intrusion protection available. To
maximize the products effectiveness simple care instructions should be followed to ensure Retro-Coat will
provide a long-term solution to vapor intrusion.
Cleaning and Maintenance of Retro-Coat
Overtime the gloss of Retro-Coat will fade and staining may occur when Retro-Coat comes in contact with
chemicals spilled on the coating surface. Any change in color or fade in the coatings appearance is due to a PH
change on the coatings surface and is not the result of products “breaking down.”
The standard smooth surface of Retro-Coat should be cleaned on a regular basis by damp mopping the floor
with conventional commercial cleaners. It is important to first remove any grease or oils by a suitable cleaner,
preferably a citrus based cleaner. Rinse with clear water to help eliminate film buildup and then allow to dry.
Never use abrasive powder cleaners like Ajax or Comet as they tend to scratch the floor.
Additional steps can also be taken to prolong the look and life of a seamless floor:
1. Protect the floor during transference of heavy equipment
2. Educate the drivers inside the building the importance of avoiding “jack-rabbit” starts and stops, as well
as keeping the metal forks lifted
3. Regular cleaning should take place as to not allow the buildup of abrasive material, such as sand or dirt,
on the coating
4. Eliminate all metal wheels
5. Change over the light-colored polyurethane wheels
6. Do not slide heavy metal totes, drums or bins across the floor. Use pallets!
7. Immediately hose down chemical spills, especially on newly laid floors, which normally take a full seven
days to fully chemically cure
8. Ask Land Science Technologies the safe window before returning the floor to service. Just because the
floor can safely take foot traffic, does not mean it is ready for motor traffic

Small Repairs
A vital component to floor maintenance is making small repairs to any holes, gouges or cracks that might
develop overtime. Such needs occur due to removal of equipment, moving of walls, additions of drains,
substrate movement and abnormal wear and tear. Repair to such areas can be done quickly and is
recommended to repair such areas before the damaged area increases and results in large-scale repairs and
possibly building downtime. Small kits are available for building maintenance personal to make spot repairs as
needed.
