NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES
NOTIFICATION OF INTENT TO CONSTRUCT OR OPERATE INJECTION WELLS
Injection Well Type "Other—Enhanced Electrical Resistance Heating"
These wells use potable water to hydrate an electrode emplaced in the subsurface that provides
heat to promote volatilization of organic compounds for extraction from the subsurface.
As provided for in 15A NCAC 02C .0230, enhanced electrical resistance heating wells are
permitted according to the criteria for in situ remediation wells specified in 15A NCAC 02C .0225
Injection wells used for enhanced electrical resistance heating are `permitted by rule"and do not require an
individual permit when constructed and operated in accordance with the rules of 15A NCAC 02C.0200.
This form shall be submitted at least 2 weeks prior to infection.
Print Clearly or Type Information. Illegible Submittals Will Be Returned As Incomplete.

G. INJECTION ZONE MAPS—Attach the following to the notification.
(1) Contaminant plume map(s) with isoconcentration lines that show the horizontal extent of the
contaminant plume in soil and groundwater, existing and proposed monitoring wells, and existing and
proposed injection wells;
(2) Cross-section(s)to the known or projected depth of contamination that show the horizontal and vertical

(3) Potentiometric surface map(s)indicating the rate and direction of groundwater movement,plus existing
and proposed wells.
Injection zone maps are provided as Attachment 1 to this notification.
H. 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.
An electrical resistance heating ((ERH)system has been installed at the facility. One hundred and seventeen
erection points within the ERH electrodes will be used to inject municipal potable water into the subsurface.
The injected water will hydrate the electrode to earth interface and facilitate the flow of electrical current in the
subsurface.Each injection point is also under vacuum to withdraw volatile organic compounds and water vapor.
UIC/EERH Notification(version 3/2/2015) Page 2

The balance of water removal and water addition will be monitored daily and the water injection rate adjusted
to ensure that the volume of water injected does not exceed the water volume withdrawn. The cumulative
maximum water injection rate for all injection points will be 5 gallons per minute and the injection pressure for
each well will be no more than 10 pounds per square inch.Injection activities are expected to take place for four
months,from 1 May 2015 to I September 2015.
I. INJECTANTS—Provide a MSDS and the following for each injectant.Attach additional sheets if necessary.
NOTE: Approved injectants (tracers and remediation additives) can be found online at
http://portal.ncdenr.org/web/wd/aps/�wpro. All other substances must be reviewed by the Division of Public
Health,Department of Health and Human Services. Contact the UIC Program for more info (919-807-6496).
Injectant: Potable water sourced from municipal water supply
Volume of injectant: 5 gallons per minute(maximum,)or 7,200 gallons per day
Concentration at point of injection: 100%potable water
Percent if in a mixture with other injectants: NA
J. WELL CONSTRUCTION DATA
(1) Number of injection wells: Proposed 117 Existing
(2) 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:
(a) well type as permanent,direct-push, or subsurface distribution system(infiltration gallery)
(b) depth below land surface of grout, screen,and casing intervals
(c) well contractor name and certification number
Well construction details are provided in Attachment 2 of this Notification.
K. SCHEDULES—Briefly describe the schedule for well construction and injection activities.
All well locations have been installed,construction applications and approvals are provided in Attachment 3 of
this notification. Injection activities are planned between 1 May 2015 and 1 September 2015.
UIC/EERH Notification(version 3/2/2015) Page 3

L. 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.
The volume of water removed and iniected will be monitored on a daily basis. The system will be adjusted to
ensure that the volume of water removed is greater than or equal to the volume injected. Other parameters
monitored_daily will include injection pressure and vacuum.,The site and surrounding area are monitored as
part of,a U.S.Environmental Protection Agency(EPA)approved Corrective Action Monitoring Plan(CAMP,).
The CAMP requires semi-annual sampline of groundwater and surface water from monitoring welts and
locations that are on-and off-site for volatile_organic compounds.The CAMP sampling locations are shown on
Figure 4-1 in Attachment 4.

Attachment 1
Injection Zone Maps
CDM Smith performed a comprehensive investigation of the Electrical Resistance Heating(ERH) area
prior to the installation of the ERH wells.This investigation included the installation of temporary
hydropunch borings and permanent wells in regolith and bedrock.The investigation results were
included as part of the RCRA Facility Investigation (RFI) Report(CDM Smith, 2013).With the
exception of Figure 1-1,ERH Well Locations,the following figures in this attachment were adapted
from the RFI Report.While several volatile organic compounds (VOCs) are present,trichloroethene
(TCE) and tetrachloroethene (PCE) are the primary compounds of concern and have the highest
concentrations among VOCs in the ERH area.The isoconcentration figures presented in this
attachment are specific to these two compounds.
The following injection zone maps are provided:
