Dear Mr. Sterling:
In accordance with the permit renewal application received on October 1, 2021 and additional
information received January 11, 2022 we are forwarding permit number WI0500448. This permit is
to inject the following additives ABC, Vitamin B-12, Sodium Bicarbonate, ZVI, Sodium Sulfite and
potable water at the above referenced facility located at 4200 Airport Drive NW, Wilson, NC 27896.
This permit shall be effective from February 1, 2022 (i.e. the day after the expiration of current permit),
until January 31, 2027 and shall be subject to the conditions and limitations stated therein, including
the requirement to submit a Final Project Evaluation (FPE) as stated in PART VII— MONITORING
AND REPORTING REQUIREMENTS. Please read the entire permit to ensure that you are aware of
all compliance requirements of the permit.
Please note the following:
• Per Permit Condition VI.1; The proposed monitoring plan, also attached (Attachment B),
shall be followed. Any additional monitoring, including groundwater, surface water, or soil
sampling, deemed necessary to ensure surface water and groundwater protection may be
established and an acceptable sampling reporting schedule shall be followed [15A NCAC 02C
.0225(k)].
• Per permit condition Part VI.5; prior to closing this permit, the Permittee must meet
groundwater quality standards or pre -injection levels, whichever concentration is higher, for all
of the injection constituents; otherwise, continued monitoring as approved in the monitoring plan
will be required until such levels can be established.
• Per permit conditions Part VI.3 &4, and IX.2(G), within 30 days after each injection event,
please provide the well construction (if not previously submitted) and injection information on
the applicable forms listed below. Note: if well construction/abandonment information is
essentially the same (e.g., direct push points or geo-probes), then only one GW-1 or GW-30
form is needed. Just indicate in the comments section on the form the total number of well

byproducts resulting from the permitted injection activity:
3. Continued monitoring until concentrations return to pre -injection values or meet the standards
specified in 15A NCAC 02L .0202, whichever are greater. The frequency, duration, and
location of monitoring shall be appropriate for site specific conditions andpotential receptors.
4. Groundwater quality parameters that do not attenuate as described in 2(A) above may warrant
a corrective action plan as provided under rule 15A NCAC 02C .0206, dependingon the type,
concentration, and distribution of the groundwater quality standards being exceeded.
PART VIII - PERMIT RENEWAL [15A NCAC 02C .0211(h)]

PART IX - CHANGE OF WELL STATUS [15A NCAC 02C .0240]
1. The Permittee shall provide written notification within 15 days of any change of status of an
injection well. Such a change would include the discontinued use of a well for injection. If a
well is taken completely out of service temporarily, the Permittee must install a sanitary seal.
If a well is not to be used for any purpose that well must be permanently abandoned according
to 15A NCAC 2C .0240, Well Construction Standards.
2. When operations have ceased at the facility and a well will no longer be used for any purpose,
the Permittee shall abandon that injection well in accordance with the procedures specified in
15A NCAC 2C .0240, including but not limited to the following:
(A) All casing and screen materials may be removed prior to initiation of abandonment
procedures if such removal will not cause or contribute to contamination of the
groundwater.
(B) The entire depth of each well shall be sounded before it is sealed to insure freedom
from obstructions that may interfere with sealing operations.
(C) The well shall be thoroughly disinfected, prior to sealing, if WQROS staff determines
that failure to do so could lead to the contamination of an underground source of
drinking water.
(D) Drilled wells shall be completely filled with cement grout or bentonite grout, which
shall be introduced into the well through a pipe which extends to the bottom of the well
and is raised as the well is filled.
(E) In the case of gravel -packed wells in which the casing and screens have not been
removed, neat -cement, or bentonite grout shall be injected into the well completely
filling it from the bottom of the casing to the top.
(F) In those cases, when, as a result of the injection operations, a subsurface cavity has been
created, each well shall be abandoned in such a manner that will prevent the movement
of fluids into or between underground sources of drinking water and in accordance with
the terms and conditions of the permit.
(G) The Permittee shall submit a Well Abandonment Record (Form GW-30) as specified
in 15A NCAC 2C .0225(1) within 30 days of completion of abandonment.

Attachment A
Attachment 1 Injection Plan (2022) Submitted 1/11/2022.
Injection Permit WI0500448 Kidde Technologies — Wilson, NC
The proposed injection plan includes injection into horizontal wells HW-1, HW-3, and HW-5 while
groundwater extraction operations continue at horizontal wells HW-2 and HW-4. A map of the horizontal
well locations is included on the following page. HW-1, HW-3, and HW-5 well screens are approximately
24 feet below ground surface (bgs), while HW-2 and HW-4 well screens are approximately 14 feet bgs.
The injection plan includes approximately 60,000 gallons (total) of injection mixture injected into wells
HW-1, HW-3, and HW-5 over a period of approximately 6 weeks. During this period, an estimated 60,000
to 300,000 gallons of groundwater will be extracted from HW-2 and HW-4, treated on -site via the existing
groundwater treatment system, and discharged to the sewer under an existing agreement with the City of
Wilson. The total injection event amendment mixture will include:
• Approximately 30,195 pounds of Anaerobic BioChem (ABC).
• Approximately 305 pounds of Vitamin B-12.
• Approximately 24,000 pounds of sodium bicarbonate.
• Approximately 12,000 pounds of zero valent iron (injectable liquid suspension provided by Tersus
Environmental).

Notes:
1.) All monitoring plan changes indicated in the updated monitoring plan relate to analysis of Central
Plume Monitoring Wells.
The horizontal well ERD injection proposed for 2020 will be within the Central Plume.
2.) In accordance with the permit, monitoring within the Western Plume, Northern Tail, and Northern
Plume will continue with
the same monitoring wells and analysis as recent monitoring events. No additional injections are
proposed or requested in
these areas at this time.
3.) Sulfate analysis required until such time as MW-15R result reaches 250 mg/L for two straight events
4.) Field parameters will include temperature, pH, dissolved oxygen, oxygen -reduction potential, and
specific conductivity.
5.) Sampling events will be performed approximately 3 months prior to the first horizontal well injection
event (baseline),
approximately 3 months after the injection event, and semi-annually thereafter.
