1.0 INTRODUCTION
The site is the Speedway 6952-C located at 2201 North Main Street, High Point, Guilford
County, North Carolina (Drawing 1 and Drawing 2). The site is a former petroleum retail
facility and convenience store and contained two 4,000-gallon capacity underground
storage tanks (USTs, one kerosene, one regular unleaded gasoline), one 3,000 gallon
capacity diesel UST, one 7,500 gallon capacity regular unleaded and two 12,000-gallon
capacity USTs (one premium unleaded and one midgrade unleaded gasoline). The USTs
were reportedly lined single walled steel and were installed in January of 1970, with the
exception of the two 12,000-gallon USTs which were installed in 1973. Additionally, two
USTs (a 12,000-gallon fuel oil #2 and a 12,000-gallon kerosene) were formerly present
at the site and closed by removal in 1994.
Please note that an inactive Leaking Underground Storage Tank incident (#12017)
is associated with the aforementioned USTs that were removed in 1994. In 2016,
Incident #12017’s risk ranking was reduced to low risk and the incident was closed
with a No Further Action (NFA) designation following the completion of a Notice of
Residual Petroleum (NORP) for groundwater contamination remaining in the subsurface
at concentrations above the North Carolina Groundwater Quality Standards (NCGQS). A
groundwater land use restriction remains in effect at the site. The NORP does not include
a soil use restriction.
On March 9, 2017, Speedway conducted hydrostatic tests on the fill port spill buckets
for the USTs. The diesel UST fill port spill bucket did not pass the test, and a UST-17A
form was filed with the North Carolina Department of Environmental Quality (NCDEQ).
The non-passing diesel UST fill port spill bucket was subsequently repaired with the
installation of a new insert and passed follow-up hydrostatic testing. A Site Check was
conducted on January 24, 2018 to determine if a release may have occurred to the
environment from the spill bucket. As reported in the Site Check Report dated March 12,
2018, soil samples collected near the fill port exceeded the soil-to-groundwater Maximum
Soil Contaminant Concentrations (MSCCs).
Following the receipt of the Site Check Report dated March 12, 2018, the NCDEQ
assigned Incident No. 45022 to the release. On April 5, 2018 Mr. Gene Mao, incident
manager for the Guilford County Department of Environmental Health, requested that
a modified Limited Site Assessment (LSA) be conducted. The scope of work included
installation and sampling of a monitoring well placed in the vicinity of the soil sample that
exceeded regulatory standards. Based on information already existing for the historical
incident (#12017), a receptor survey was not required. NCDEQ issued a Notice of No
Further Action letter for this incident on August 17, 2018.
In November of 2019, Speedway conducted a Site Check on a piping manifold sump
after a fuel/water mixture was found in the sump. Soil borings were advanced adjacent
to the sump and the sampling results indicated detections of TPH-GRO and DRO at
concentrations below the regulatory action levels. NCDEQ opened Incident No. 45335
and then immediately closed the incident.
In the Spring of 2020, Speedway decided to close the station and remove the UST
system at the site. A UST Closure Report was prepared and submitted to the UST
Section. Free product was visible in the UST excavation upon removal of Tank 3 (diesel
UST) on the east side of the store. This product was removed with a vacuum truck and
soils were excavated in this area to remove the petroleum. Petroleum-impacted soils
were identified with the removed USTs and piping. Contaminant concentrations above
the NCDEQ’s action level of 50 mg/kg for TPH-GRO and 100 mg/kg for TPH-DRO were
measured in the basin following UST removal and subsequent over-excavation activities.
Soil samples collected for Risk-Based Corrective Action (RBCA) analyses also exceeded
NCDEQ soil to groundwater and residential MSCCs.
Based upon the results of the UST closure, NCDEQ requested that a monitoring well
be installed in the former location of the diesel UST to check for the presence of free
product. In November 2020, a monitoring well (MW-11) was installed and sampled.
Free product was not present in the well, but benzene and EDB exceeded their GCLs.
Based on these results, NCDEQ assigned a new Incident No. (47271) and requested
completion of a CSA. Three additional monitoring wells (MW-12 through MW-14) were
installed in May of 2021. Sampling results indicated that the contaminant plume had not
been defined to the GCL and additional monitoring wells would be required to complete
the CSA.
Two additional monitoring wells, MW-15 and MW-16, were installed on February 9,
2022 to further delineate the contaminant plume. During installation of these wells,
several wells were gauged for the presence of free product. At that time, well MW-12
was observed to contain a free product thickness of approximately 1.13
feet. Correspondence with NCDEQ's Gene Mao about this well led to the approval
of an Aggressive Fluid Vapor Recovery (AFVR) event, which is documented in this
report. Selected correspondence with NCDEQ is provided in Appendix A.
The opinions included herein are based on our experience and the information obtained
during the study. This report is based on limited observations made on the dates noted
using the procedures described herein. If additional information becomes available, we
request the opportunity to review the information, reassess the potential environmental
concerns and modify our conclusions and recommendations, if appropriate.

2.0 FIELD ACTIVITIES
Well Gauging and Free Product Thickness
Monitoring wells MW-11, MW-12, MW-13, and MW-15 were gauged for free product
thickness on March 3, 2022, prior to the AFVR event. Based on the readings from the
oil/interface probe, it was determined that well MW-12 contained approximately 0.35 feet
of free product. The other three wells did not contain free product at that time.
Approximately 15 minutes after the conclusion of the AFVR event, liquid level
measurements were performed on the same four wells, with well MW-12 exhibiting a free
product thickness of 0.04 feet.
Mid-Atlantic re-mobilized to the site on April 11, 2022 to perform follow-up free product
gauging. Monitoring wells MW-11, MW-12, MW-13, and MW-15 were gauged for free
product thickness and well MW-12 exhibited 0.04 feet of free product. The other wells did
not exhibit measurable free product thicknesses. Water level and free product thickness
measurements (including historical measurements made by Mid-Atlantic) are included in
Table 1.
Recovered Free Product
The AFVR event was conducted over an 8-hour period on March 3, 2022, extracting
from wells MW-11 and MW-12. Well construction records for these wells are provided
in Appendix B. Field measurements obtained during the event are provided in Appendix
C. AFVR services were provided by Eastern Environmental Management, LLC (Eastern
Environmental) of Rocky Mount, North Carolina. A summary of the AFVR event is
provided in Table 2. As summarized, 307 gallons of petroleum-contact water was
recovered during the AFVR event. No measurable free product was observed in the
vacuum truck recovery tank.
The estimated amount of recovered gasoline from emissions during the AFVR event
was calculated at approximately 0.08 gallons. This volume appears to be lower than
expected, based on the volume of free product on the water table, and could be related
to measurement equipment (PID and/or anemometer) accuracy. The calculations for
converting vapor emissions (in pounds) to gallons of gasoline are provided in Appendix
D.
The Material Manifest and Certificate of Disposal for disposition of recovered liquids are
included in Appendix E. The material was transported to Eastern Environmental’s facility
in Rocky Mount, North Carolina for disposal.

3.0 FREE PRODUCT RECOVERY COST ANALYSIS
Cost Estimate for AFVR
An AFVR event was conducted at the site on March 3, 2022, with no measurable free
product as liquid and 0.08 gallons of free product recovered as vapor.
Based on these results, the cost to perform an AFVR event was calculated as follows:
Description Details Cost
Field Supervision 1 event @ 8 hours/event @ $93/hour $744.00
Travel Trust Fund lump sum cost $250.00
Cost of AFVR 1 event @ $1,357.45 (includes 307 gallons
disposal)$1,357.45
Total, Per Event $2,351.45
Total, Per Gallon ($2,351.45 / 0.08 gal)$29,383/gal
4.0 CONCLUSIONS AND RECOMMENDATIONS
Mid-Atlantic concludes the following:
• The AFVR event removed a total of 307 gallons of petroleum-contaminated water
and approximately 0.08 gallons of free product from two site monitoring wells;
• Free product is present on the water table, but at a reduced thickness after the
AFVR;
• AFVR at the site appears to be a cost-prohibitive option for product recovery.
Mid-Atlantic recommends the following:
• Installation of a passive recovery device (passive bailer or petroleum-absorbent
sock);
• Additional free product gauging events to maintain the passive recovery device
and monitor free product thickness; and
• Submittal of this report to NCDEQ.

Please see attached PATA request form to perform one AFVR event and a return trip approximately 2 weeks later to
gauge the wells again, then followed by report preparation. I’ve included a provision for the follow-up gauging for both
MW-11 (GCL exceedance well) and MW-12 (well with product recently found) such that we can claim either 2.087 (if
there is product) or 4.090 (if there is no product). Only the applicable task code will be charged, of course. Please let me
know if any questions. Thanks,

Hi Gene-
We are putting in the CSA wells and one of the existing wells, MW-12 (see attached map), has 1.13 feet of free product
in it. Speedway would like to do an AFVR to remove it. Do we need pre-approval for that?

PMRg = lb/hr, pollutant mass removal rate of of VOC's as gasoline
PMR = lb, pollutant mass removal of VOC's as gasoline
EQUATIONS
PPMwet = PPMmeasured
PPMdry = (PPMwet)/(1-Bws)
PPMc = (PPMd)(K)
Cc:m = (PPMc)(Mc / K3)
Cc = (Cc:m)(62.43x10-9 lb-m3/mg-ft3)
PMRc = (Cc)(Qstd)(60 min/hr)
PMRg = (PMRc)(Mg/Mcg)
PMR = (PMRg)(#minutes/60)
