NOI WI0400469 RE: Walsers Service Permit
Thank you for submitting the Notice of Intent to Construct or Operate Injection Wells (NOi} for the above referenced
site.
Please remember to submit the following regarding this injection activity:
1) Well Construction Records (GW-1) and Abandonment Records (GW-30) when completed. Please provide copies of
the GW-ls and GW-30s if not already submitted (ori ginals go the address printed on the form): NOTE: Direct push or
Geoprobe wells are considered wells and require construction (GW-1} and abandonment forms (GW-30}. If well
construction/abandonment information is the same for the wells, only one form needs to be completed-just indicate
total number of injection points in the Comments/Remarks section of form . These forms can be found on our website
at
http://de q .nc.gov/about/divisions /water-resources /water-resources-permits /wastewater-branch /ground-water-
p rotection /ground-water-re porting-forms
2) Injection Event Records (IER). All injections, including air and passive systems require an IER. The IER can be
modified for air sparge wells (e.g., air flow 'continuous' for date or rate of injection, etc.).
You can scan and send these forms directly to me at Shristi.shrestha @ncdenr.gov or via regular mail to address
below. When submitting the above forms, you will need to enter the nine..:digit alpha-numeric number on the form
(i.e., WIOXXXXXX) that has been assigned to the injection activity at this site. This notification has been given the
deemed permit number WI0400469. This number is also referenced in the subject line of this email. You may if you
wish, scan and send back as attachments in re p ly to this email. as it will already have the assigned deemed permit
number in the subject line.

clothing during clean-up:Use a NIOSI I/MSI`IA approved respirator if there is a risk of exposure to
dust/fume at levels exceeding the exposure limits_ Do not touch damaged containers ar spilled
material unless wearing appropriate protective clothing. Ensure adequate ventilation. Local
authorities should be advised If significant spillages cannot be contained. For personal protection,
see section 8 of the SOS.
Eliminate all ignition sources {no smoking, flares, sparks, ar flames in immediate area). Collect
dust using a vacuum cleaner equipped with HEPA filter. Keep combustibles (wood, paper, oil, etc.)
away from spilled material. Ventilate the contaminated area. Stop the flow of material, if this is
without risk. Absorb in vermiculite, dry sand or earth and place into containers.
Large Spills: Sweep up or vacuum up spillage and collect in suitable container for disposal. Shovel
the material into waste container, Mlnimize dust generation and accumulation_ Avoid the
generation of dusts during dean -up. Fallowing product recovery, flush area with water.
Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to
remove residual contamination.
Never return spills to original containers for re -use. Place all material into loosely covered plastic
containers for later disposal. For waste disposal, see section 13 of the SDS. Wear appropriate
protective equipment and clothing during clean-up.

1.2 Summary of Analytical Results and Free Product Thicknesses):
1.2.1 Date(s) of Sampling Event: February 23, 2017 (MW-1) and May 8, 2017 (MW-1,
MW-2, and MW-4 through MW-9)
1.2.2 Existing Area Receptors:
The most recent receptor update was conducted on November 8, 2012 to determine if
the status of the surrounding supply well use had changed since the last receptor
survey was conducted. During the November 8, 2012 receptor update, Shield
personnel spoke to several of the residents within a 1,000 foot radius of the site
incident and provided receptor survey forms.
Based on the information that Shield personnel were able to obtain, it appears that the
general status of the surrounding supply well usage has not changed. During the
November 2012 receptor update, there was still at least one party within 500 feet of
the site (the owner of WSW-4) and one party between 500 to 1,000 feet of the site (the
owner of WSW-10) that were not willing to connect to municipal water.

Appendix A
• Historical Groundwater Analytical Data:
Refer to the following table for historical groundwater analytical data.
Refer to Table: Table 4
• Dissolved Phase Plume Size and Location:
Two sampled monitoring wells (MW-1 and MW-2) exhibited petroleum
compounds at concentrations exceeding the 15A NCAC 2L Groundwater
Standards (2L Standards). In February 2017, MW-1 had concentrations of total
xylenes and naphthalene (1469.5 ug/L and 230 ug/L, respectively) that exceeded
the 2L standard. In May 2017, MW-1 and MW-2 had concentrations of only
naphthalene (29.7 ug/L and 13.4 ug/L, respectively) that exceeded the 2L
standard. The estimated naphthalene plwne is approximately 55 feet in length
and 30 feet wide.
• Proximity of Plume to Nearest Receptor(s):
The nearest in use water supply well is approximately 400 feet from the source
(WSW-4).
• Predictive Rate of Contaminant Transport:
This contaminant plume has been very stable for years and is not migrating.
Naphthalene and total xylenes were the only constituents greater than the 2L
Standards during the most recent sampling events. Ref er to the following
table(s) and figure(s):

2.1 Summary of Remediation Activities to Date:
Monitoring Report
June 28, 2017
Page4
• An Air Sparge (AS), Soil Vapor Extraction (SVE), and Groundwater Recovery
System (GRS) were installed and commenced operation on January 28, 1999.
• The Air Sparge system includes two 2-inch diameter sparge wells (AI-I and AI-2).
• The Groundwater Recovery System includes one vapor enhanced groundwater dual
phase recovery well (VERW-1).
• Treated groundwater is discharged in an injection well (MW-3).
• The remediation system was shut down in December 2004 due to suspension of
directed work on North Carolina UST Trust Fund sites.
• The remediation system was restarted on May 1, 2007 following the receipt of the
NCDEQ Notice of Regulatory Requirements (NORR).
• Advanced Oxygen Releasing Compound (ORC) socks were installed in monitoring
wells MW-I and MW-2 on March 30, 2017 (permit number Wl 0400469).
3.0 CONCLUSIONS AND RECOMMENDATIONS
3.1 Conclusions:
• Free Product was not detected in the on-site wells during this reporting period, nor
has it been detected previously.
• Dissolved phase petroleum constituent concentrations were below 2L Standards in
aJl monitoring wells except MW-1 and MW-2. Only naphthalene was above the 2L
Standard and only in monitoring wells MW-1 (February 2017 and May 2017
sampling events) and MW-2. Total xylenes were above the 2L Standard in
monitoring well MW-I only during the February sampling event.
• In monitoring well MW-1 naphthalene concentrations have decreased from 230
ug/L to 29.7 ug/L, and total xy]enes concentrations have decreased from 1469.5
ug/L to 33.5 ug/L since the February 2017 sampling event.
• Naphthalene concentrations in monitoring well MW-2 have increased from 4.6 ug/L
to 13.4 ug/L since the November 2016 sampling event.
• Overall, the levels of contaminants in MW-1, MW-2, and the surrounding
monitoring wells have decreased since the start up of the remedial system.
• The plume is contained in the vicinity of monitoring wells MW-I and MW-2. The
lighter, more mobile contaminants have been successfully rernediated at the site.
Low concentrations of the heavier, slower moving compounds (such as
naphthalene) remain, but are also being remediated at a slower rate.
• The plume has become considerably smaller since the initial startup of the
remediation and contaminants are nearly below the 2L Standards in the monitoring
wells.

3.2 Recommendations:
Monitoring Report
June 28, 2017
Page 5
• Because two water supply well owners within 1,000 feet of the site are not wilJing
to connect to municipal water, the risk ranking of the site remains high.
• Shield recommends the remediation system remain running, in order to decrease
concentrations of the heavier compounds. Shield recommends the continued use of
ORC socks in MW-1 and MW-2 to help bioremediate/oxidize the remaining
contamination in these two wells.
• Shield recommends semi-annual sampling events for MW-1, MW-2, and MW-4
through MW-9.

1.0 DISCUSSION OF REMEDIATION ACTIVITIES
• Summar of Remediation Activities to Date:
• An Air Sparge (AS), Soil Vapor Extraction (SVE), and Groundwater Recovery
System (GRS) were installed and commenced operation on January 28, 1999.
• The Air Sparge system includes two 2-inch diameter sparge wells (AI-I and AI-2).
• The Groundwater Recovery System includes one vapor enhanced groundwater dual
phase recovery we11 (VERW-1).
• Treated groundwater is discharged in an injection well (MW-3).
• The remediation system was shut down in December 2004 due to suspension of
directed work on North Carolina UST Trust Fund sites.
• The remediation system was restarted on May 1, 2007 following the receipt of the
NCDENR Notice of Regulatory Requirements (NORR).
• Advanced Oxygen Releasing Compound (ORC) socks were installed in monitoring
wells MW-1 and MW-2 on March 30, 2017 (permit number W10400469), to
increase bioremediation and oxidation of the residual contamination.
1.1 Reportin2 Period -Remediation System Status and Operational Data:
l.l.1 Groundwater Recovery System
• Scheduled Operational Time (for Reporting Period):
-5/25/2017)
186 days (11/19/2016
• Actual Operational Time (for Reporting Period): 179 days
• Actual Operational Efficiency (for Reporting Period): 96.2%
• Summary of Down Time: The GRS was found down on arrival on the
12/13/2016 site visit due to a blower tripped. The blower was restarted, and has
been continuously running since the 12/13/2016 site visit. The GRS does not
have an hour meter, therefore an assumption was made that the system was
down half the time between site visits.
• System Sampling Frequency: Annually, based on the groundwater

Remarks: The SVE system has run continuously since
April 6, 2016. Because no SVE sampling is
conducted, we cannot estimate how many
pounds of contamination have been removed
by the SVE system.
1. 1 .3 AS System
• Scheduled Operational Time (for Reporting Period): 186 days (11/19/2016
-5/25/2017)
• Actual Operational Time (for Reporting Period): 169 days
• Actual Operational Efficiency (for Reporting Period): 90.8%
• Summary of Down Time: The AS system was down during the start of
this reporting period because of an ineffective motor, the motor was removed
and replaced on November 29, 2016 and the AS system was restarted. On the
December 13, 20 I 6 site visit the AS system was found down due to a tripped
wire. The AS system does not have an hour meter, therefore an assumption was
made that the system was down half of the time between the site visits The
system was switched back on and remained runnjng throughout the reporting
period.

Because no AS sampling is conducted, we
cannot estimate how many pounds of
contamination have been removed by the AS
system.
• Total Gallons of Water Treated During the Period
• Approximately 44,353.1 gallons of groundwater were treated by the GRS between
November 19, 2016 and May 25,2017 based on operation and maintenance field
notes.
• It is unknown how much water has been treated by the SVE and AS systems.

1.2 Monthly Operation and Maintenance Costs:
Corrective Action Performance Report
June 30, 20 I 7
Page 3
• The operation and maintenance cost during this reporting period was approximately
$1,723.05 per month.
1.3 Mass of Contaminant Removed:
• Based on the Influent/Effluent data in Table 2 the GRS system recovers an average of
0.0076 pounds of BTEX compounds per day.
• Dissolved phase petroleum constituents exceeding the 15A NCAC 2L Groundwater
Standards (2L Standards) were only detected in monitoring wells MW-1 and MW-2.
Therefore, the plume size above the 2L Standards is localized near MW-1 and MW-2.
Only naphthalene was detected in monitoring wells MW-1 and MW-2. In monitoring
well MW-l, naphthalene levels were 230 ug/L (February 2017 sampling event), 29.7
ug/L (May 2017 sampling event) and monitoring well MW-2 naphthalene levels were
13.4 ug/L. Monitoring well MW-1 also had a concentration of total xylenes above
the 2L Standard at a concentration of 1469.5 ug/L in February 2017, but not above
the 2L Standards in May 2017.
Refer to Table(s): Tables 1 and 2
1.4 Future Remediation Activities:
• Recommend continued operation of the Air Sparge, SVE and GRS pursuant to the
CAP.
• Continue to monitor system operation with adjusted flow.
• Recommend the continued use of ORC socks in MW-1 and MW-2 to help
bioremediate/oxidize the remaining contamination in these two wells.
• No other additional remedial activities are recommended or planned.
1.5 Gallons of Recovered Free Product:
• No documented amount of free product has ever been detected at the site.
1.6 Discharge/Non-Discharge/POTW Permit:
• The AS and SVE systems do not require any permits for operation.
• The GRS currently operates under discharge permit #WQ0015102 , which expires
January 31, 2018. Shield plans on submitting a NPDES General Permit extension in
June 2017.
• Advanced Oxygen Releasing Compound (ORC) socks were installed in monitoring
wells MW-1 and MW-2 on March 30, 2017 under permit number W 10400469 .

2.0 CONCLUSIONS AND RECOMMENDATIONS
2.1 Performance and Efficiency of the Remediation System:
• The GRS system operated for 179 days out of 186 days from November 19, 2016
through May 25, 2017 for operational percentage of 96.2%.
• The SVE system operated for 186 days out of 186 days from November 19 , 2016
through May 25, 2017 for operational percentage of I 00%.
• The AS system operated for 169 days out of J 86 days from November 19, 2016
through May 25, 2017 for operational percentage of 90.8%.
• Approximately 29.0542 pounds of BTEX have been recovered by the GRS from June
25, 2002 through September 29, 2016, and an average of 0.0076 pounds of BTEX is
removed per day.
• Because no SVE and AS sampling is conducted, we cannot estimate how many
pounds of contamination have been removed by t.he SVE system.
2.2 Recommended Modifications to the System:
• Focus remedial effort in MW-1 and MW-2 area to finish the cJean-up of the
contamination. Based on the historical analytical data, we anticipate that the
dissolved phase petroleum constituent concentrations will be cleaned up to below the
2L Standards within a few more reporting periods.
