Deemed Permitted GW Remediation NOI Rev. 3-1-2016 Page 3
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 and deeper source zones and within the “hotspot” of the dissolved
contaminant plume. The injection will utilize Beverage Remediation Product (BRP).

Scope
The small scale injection will focus on the shallow and deeper 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 Analysis
pH Methane, Ethane and Ethene
Temperature Chloride
Dissolved Oxygen Total Organic Carbons
Specific Conductivity Total and Dissolved Metals
(Arsenic, Chromium, Iron and
Manganese)
Oxidation-Reduction Potential

Total and Dissolved Phosphorous

Following the baseline sampling event, CATLIN will mobilize to the site and conduct a BRP injection
event utilizing existing monitoring wells 61SMW-07R, 61SMW-08, 61DMW-17 and 61DMW-30.
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 an additional
BRP injection and again perform post injection monitoring. 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.
J. APPROVED INJECTANTS – 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 http://deq.nc.gov/about/divisions/water-
resources/water-resources-permits/wastewater-branch/ground-water-protection/ground-water-approved-injectants.
All other substances must be reviewed by the DHHS prior to use. Contact the UIC Program for more info
(919-807-6496).

Injectant: Beverage Remediation Product
Volume of injectant: 2,000 to 3,000 gallons per event. Two events
Concentration at point of injection: 10 %
Percent if in a mixture with other injectants: <2% NaHCO3, >1% Na2HPO4, 10% BRP, 88% water

Injectant: Sodium Bicarbonate (NaHCO3)
Volume of injectant: 250 lbs – 750 lbs per event
Concentration at point of injection: 0.1 to 0.3 lbs/gal
Percent if in a mixture with other injectants: <2% NaHCO3, >1% Na2HPO4, 10% BRP, 88% water
Deemed Permitted GW Remediation NOI Rev. 3-1-2016 Page 4

Injectant: Sodium Phosphate (Na2HPO4)
Volume of injectant: 75 lbs – 100 lbs per event
Concentration at point of injection: 0.025 to 0.05 lbs/gal
Percent if in a mixture with other injectants: <2% NaHCO3, >1% Na2HPO4, 10% BRP, 88% water

Beverage Remediation Product MSDS
Currently, there is not a Material Safety Data Sheet (MSDS) available for BRP. 29CFR1910.1200(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

(1) Number of injection wells: Proposed 4 Existing (provide GW-1s)
(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 attached well logs.
Deemed Permitted GW Remediation NOI Rev. 3-1-2016 Page 5
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 conduct a baseline sampling event in March/April 2018.
 We will conduct the first BRP injection event in April 2018..
 Following the injection event, CATLIN will conduct post BRP sampling on a quarterly basis as
needed.
 The second BRP injection event will be conducted once it appears the BRP from the initial injection
event has been depleted.

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
(Arsenic, Chromium, Iron and
Manganese)
Oxidation-Reduction Potential

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.
