NOTIFICATION OF INTENT TO CONSTRUCT OR OPERATE INJECTION WELLS
The follmving are "permitted by rule" and do not require an individual permit when constructed in accordance
with the rules of 15A NCAC 02C .0200. Tliis form shall be submitted at least 2 weeks p,·ior to construction.
AQUIFER TEST WELLS '(ISA NCAC 02c .0227)
These wells are used to inject uncontaminated fluid into an aquifer to determine aquifer hydraulic characteristics.
IN SITU REMEDIATION (ISA NCAC 02C .0225) or TRACER WELLS (1SA NCAC 02c .0229):
1) Passive Injection Systems .. In-well delivery systems to diffuse injectants into the subsurface. Examples include
ORC socks, iSOC systems, and other gas infusion methods.
2) Small-Scale Injection Operations -Contaminant plumes located entirely within a land surface area not to
exceed 10,000 square feet. For tracer tests in uncontaminated areas the area of influence of the injection well(s) shall
be entirely within a land surface area not to exceed 10,000 square feet. Au individual permit shall be required for
test or ti·eatment areas exceeding 10,000 square feet.
3) Pilot Tests ... Preliminary studies conducted for the purpose of evaluating the technical feasibility of a
remediation strategy in order to develop a full scale remediation plan for future implementation, and where the
surface area of the injection zone wells are located within an area that does not exceed five percent of the land
surface above the known extent of groundwater contamination. An individual permit shall be required to conduct
more than one pilot test on any separate groundwater contaminant plume.
4) Air Injection Wells -Used to inject ambient air to enhance in-situ treatment of soil or groundwater.

G. In iection Zone Maps
A contaminant concentration map and a benzene isoconcentration map taken from the report titled Fonner
Preslar's Exxon Transmittal for April 2011 prepared by Solutions-IES dated June 15, 2011 are attached.
These drawings illustrate the lateral extent of contamination at the site. The estimated area covered by the
1 µg/L benzene isocontour is approximately 21,060 sq ft. The footprint of the planned pilot study is
approximately 8 ft x 16 ft (128 sq ft), representing less than 1 % of the entire plume. The treatment of
treatment for the pilot test is planned to be less than 5% of the entire plume. Based on this plan, the pilot
study may be permitted by rule.
The Comprehensive Site Assessment (CSA) report provided by S&ME, Inc.(S&ME Project No.
1040.98.0lB dated August 27, 2001), suggested that the vertical extent of contamination is between the
total depth ofMW-1 (24.5 feet below ground surface [bgs]) where the groundwater in MW-1 is impacted
by petroleum hydrocarbons and MW-5 ( ~50 feet bgs) where petroleum hydrocarbons are not detected.
Thus, the projected interval of contamination is between approximately 10 feet bgs, the depth to
groundwater, and 37 feet bgs. The target interval for the pilot test is from 10 to 20 feet bgs. In general,
the geology of the site is described by S&ME as distinct layers of sands, and clays above partially
weathered rock. Cross-sections of the lithology, also provided by S&ME, are attached. Based on the
referenced CSA report, the groundwater flow velocity is estimated at 0.005 ft/day and is generally
flowing toward the southeast. Solutions-IES has confirmed the direction of groundwater flow in the
Solutions-IES reported dated June 15, 2011 and shown in the attached drawing.
H. Description of Proposed Iniection Activities
Because the historical monitoring at the former Preslar' s Exxon Site suggests that the plume is anaerobic and
sulfate limited, sulfate enhancement is expected to be a cost-effective treatment approach to petroleum impacted
groundwater when compared to other possible alternatives such as in situ chemical oxidation or soil vapor
extraction/air sparge. However, before committing to full scale, a pilot test is necessary to test the effectiveness
of sulfate enhancement for this site.
The proposed location of the injection well field including three pilot test monitoring wells is also shown on the
isoconcentration map. A new injection well and three new monitoring wells will be installed. The injection
well will be located near MW-4, up gradient of three pilot test monitoring positioned 3, 5, and 10 feet down
gradient, respectively, from the injection well within the footprint described in Part G above.
As shown in the cross-sections provided with this submittal, the depth to groundwater in the vicinity ofMW-4 is
10 to 12 ft bgs. Thus, the 1-inch diameter injection well will be installed to a depth of approximately 21 feet
bgs and screened beneath the water table from 11 to 21 feet bgs. The 1-inch diameter monitoring wells will be
installed to a depth of 20 feet bgs and screened across the water table from 10 to 20 feet bgs. These monitoring
wells and potentially others existing at the site will be monitored for approximately nine months to identify
degradation trends and rates as well as substrate longevity and ultimately treatment effectiveness.
J. Well Construction Data
The well contractor is expected to be Parratt Wolff, and the certification number of Gmy Ellington is 3367-A
Mr. Ellington will assist Solutions-IES with injection planning and performance.

L. Monitorin g Plan
The frequency of monitoring of each of the four wells is proposed for pre-injection, 1 month, 3 months, 6
months, and 9 months post-injection, but the frequency may be modified and will ultimately depend on the
achieved radius of influence, groundwater flow velocity and observed degradation. At the pre-injection
monitoring event, groundwater samples will be collected and analyzed for sulfate, and for volatile organic
compounds (VOCs) by EPA Method 601/602 extended to include 1,2-dichloroethane,
Naphthalene,isopropyl ether (IPE), and methyl tert-butyl ether (MTBE). Downgradient monitoring well
(closest to the injection well) will also be analyzed for sulfate-reducing bacteria by qPCR. At the four
post-injection monitoring events, the collected groundwater samples will be analyzed for VOCs by EPA
Method 601/602 extended to include 1,2-dichloroethane, naphthalene,isopropyl ether (IPE), and methyl
tert-butyl ether (MTBE) and sulfate. At 6-month post-injection sampling event, the monitoring well at
the 3 foot distance will again be sampled for sulfate-reducing bacteria to assess whether population
changes have occurred. Although the expected concentration of sulfate near the injection point is planned
to be approximately 1000 mg/L, the concentration of sulfate is not expected to exceed 250 mg/L beyond
the treatment zone of the pilot test. The data will also be used to estimate the rate that sulfates dissipates
from the injection zone over time.
A final report summarizing the monitoring activities will be prepared and attached to a Corrective Action
Plan Addendum.
