Deemed Permitted GW Remediation NOi Rev . 3-1-2016 Page2
I. DESCRIPTION OF PROPOSED INJECTION ACTIVITIES -Provide a brief narrative regarding the
purpose, scope, and goals of the proposed injection activity. This should include the rate, volume, and
duration of injection over time.
Purpose
The purpose of this small scale injection is to reduce dissolved chlorinated aliphatic hydrocarbon (CAH)
concentrations within the shallow source zone and within the "hotspot" of the dissolved contaminant
plume. The injection will utilize Beverage Remediation Product (BRP) along with Dynamic Pulse Air
Sparging.
Scope
The small scale injection will focus on the shallow source zone and intermediate dissolved groundwater
contamination. Prior to the BRP injection, CATLIN will conduct a baseline sampling event to determine
current site conditions. We will collect representative groundwater samples from select monitoring wells
for analysis of CAH compounds per Standard Method (SM) 6200 and the following natural attenuation
parameters:
Field Test Laboratory Analvsis
pH Methane, Ethane and Ethene
Tem perature .Chloride
Dissolved Oxygen Total Organic Carbons
Specific Conductivity Total and Dissolved Metals
Oxidation-Reduction Potential (Arsenic, Chromium, Iron and
Manganese)
Total and Dissolved Phosphorous
Following the baseline sampling event, CATLIN will mobilize to the site and conduct a BRP injection
event utilizing a number of the proposed monitoring/injection wells and existing monitoring wells MW-
04D and/or 06IMW-21. Following the injection event, we will perform post-BRP injection sampling
events at 1 month, 3 months, 6 months, 9 months and 12 months (if needed) to track the BRP movement in
the subsurface and the impacts on the groundwater contaminants. Section M describes performance
monitoring in more detail.
Once it appears that the injected BRP has been close to exhausted, CATLIN will conduct a Dynamic Pulse
Sparge Event utilizing wells MW-4D, 06IMW-0l, 06IMW-21 and three proposed sparge wells (if
needed). The Dynamic Pulse Sparge event temporarily displaces water as air is injected into the
subsurface. The displaced water creates a "washing" action through the subsurface soils and helps loosen
and mobilize potentially trapped contamination within the interstitial zones above and/or between the
monitoring wells, which can then be treated.
The small scale injection is anticipated to consist of two BRP injection events and two Dynamic Pulse
Sparge events. CATLIN will evaluate the need for additional injections based on the results of the
performance monitoring . We will modify the frequency, volume and concentration of the BRP injection
to provide sufficient amounts of electron donor that produce a carbon loading rate of at least 100
milligrams per liter (mg/L) and optimize groundwater pH.
Deemed Permitted GW Remediation NOi Rev. 3-1-2016 Page 3
J. APPROVED INJECT ANTS -Provide a MSDS for each injectant. Attach additional sheets if necessary.
NOTE: Only injectants approved by the NC Division of Public Health, Department of Health and Human
Services can be injected. Approved injectants can be found online at h ttp ://de g.nc.gov/ahout/divisions/water-
resources/water-rcsources-permits/wastewater-branch/1IT0und-water-protection/ground-water-approved-iniectants.
All other substances must be reviewed by the DHHS prior to use. Contact the UIC Program for more info
(919-807-6496).

Beverage Remediation Product MSDS
Currently, there is not a Material Safety Data Sheet (MSDS) available for BRP. 29CFR1910. l 200(b )(5)(iii)
exempts food, food additives, color additives, etc. from MSDS requirements. High Fructose Corn Syrup
(HFCS) accounts for the majority of the BRP with the remaining ingredients compromising less than 0.5% of
the solution. BRP and HFCS are included on the NCDEQ Division of Water Quality (DWQ) Underground
Injection Control (UIC) list of approved injectants .
MSDS for Sodium Bicarbonate and Sodium Phosphate have been included in attachments.
K. WELL CONSTRUCTION DATA
Number of injection wells: --=2=0 __ .Proposed'-_~3 ___ Existing (provide GW-ls) (1)
(2) For Proposed wells or Existing wells not having GW-1s, provide well construction details for each
injection well in a diagram or table format. A single diagram or line in a table can be used for
multiple wells with the same construction details. Well construction details shall include the
following (indicate if construction is proposed or as-built):
(a) Well type as permanent, Geoprobe/DPT, or subsurface distribution infiltration gallery
(b) Depth below land surface of casing, each grout type and depth, screen, and sand pack
(c) Well contractor name and certification number
See Figure K.1 for injection well locations.
See Figure K.2 for typical monitoring/injection well details.
Deemed Permitted GW Remediation NOi Rev. 3-1-2016 Page 4
L. SCHEDULES -Briefly describe the schedule for well construction and injection activities.
The following is an anticipated schedule for well construction and injection activities:
• CATLIN will install the proposed monitoring/injection wells prior to injection to further delineate the
source zone contamination.
• We will conduct the first BRP injection event in November/December 2017.
• Following the injection event, CATLIN will conduct post BRP sampling on a quarterly basis as
needed.
• CATLIN will conduct the first Dynamic Pulse Sparge event when the BRP is close to depletion,
which will be field verified .
• The second BRP injection event will be conducted roughly two weeks following the Dynamic Pulse
Sparge event.
• CATLIN will conduct the second Dynamic Pulse Sparge event follow!ng the second BRP event.
M. MONITORING PLAN -Describe below or in separate attachment a monitoring plan to be used to determine
if violations of groundwater quality standards specified in Subchapter 02L result from the injection activity.
During each sampling event, CATLIN will collect groundwater samples for SM 6200 analysis . In addition, we
will collect the following natural attenuation parameters:
Field Test Laboratory Analysis
pH Methane, Ethane and Ethene
Temperature Chloride
Dissolved Oxygen Total Organic Carbons
Specific Conductivity Total and Dissolved Metals
Oxidation-Reduction Potential (Arsenic, Chromium, Iron and
Manganese)
Total and Dissolved Phosphorous
The following summarizes the proposed sampling events:
• Pre-Injection Sampling -CATLIN will conduct a baseline sampling event and collect groundwater
samples from select monitoring wells prior to the initial BRP injection.
• Post BRP Sampling -Following each BRP injection, CATLIN will collect groundwater samples 1
month, 3 months, 6 months, 9 months and 12 months (if necessary) from select monitoring wells.
• Post Dynamic Pulse Sparge Sampling -Two weeks following each Dynamic Pulse Sparge Event, we
will collect groundwater samples from select monitoring wells to be analyzed per SM 6200.

extinguishing media appropriate to the surrounding fire.
Extinguishing Media: Substance is noncombustible; use agent most appropriate to extinguish
surrounding fire. Use agent most appropriate to extinguish fire. Do NOT get water inside containers.
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Clean up
spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty
conditions. Provide ventilation. Do not get water inside containers.
Section 7 - Handling and Storage
Handling: Use with adequate ventilation. Minimize dust generation and accumulation. Avoid
prolonged or repeated contact with skin. Avoid breathing vapors from heated material. Avoid contact
with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Do not
allow contact with water. Keep from contact with moist air and steam.
Storage: Store in a tightly closed container. Store in a cool, dry, well -ventilated area away from
incompatible substances. Store protected from moisture.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash
