RE: Incident Closure Procedures
Former William T. Johnson Property
112 Green Acres Lane, Greensboro, NC 27410
Incident Number: 48731 / Risk Classification: Low
Ranking: L60D

Dear Mr. Lerew:

On behalf of William T. Johnson, Pyramid Environmental & Engineering, P.C. completed
the tasks required by the North Carolina Department of Environmental Quality (NC
DEQ) for regulatory closure of the above referenced site/incident. As required, a Notice
of Residual Petroleum (NRP) was recorded at the Guilford County Register of Deeds and
the public notification pursuant to 15A NCAC 2L.0115(k) was completed for the subject
property. A copy of the Conditional Notice of No Further Action (CNNFA) letter for the
referenced site issued by the NC DEQ on March 16, 2023, is included as Attachment A.

Site History
In October 2022, Pyramid conducted a pre-purchase Phase I Environmental Site
Assessment (ESA) on the subject property on behalf of the National Park Service (NPS).
As part of the Phase I ESA, Pyramid installed two soil borings adjacent to an existing
550-gallon heating oil underground storage tank (UST) using a hand auger and evidence
of a petroleum release was discovered in the soil boring closest to the fill port. One soil
sample (SB2-7’) was collected and shipped overnight to Red Lab in Wilmington, NC for
laboratory analysis. The lab results for SB2-7’ indicated total petroleum hydrocarbon
(TPH) concentrations that exceeded the NCDEQ actions limits. As part of this
investigation, Pyramid was authorized by the NPS and the current property owner to
report the petroleum release to the NCDEQ. A copy of the 24-hour Notification (Form
UST-61) with Red Lab Report and other supporting documentation is included as
Attachment B. Based on the low risk classification of the site, the incident qualified for
incident closure using the NRP process, which included removing the residual heating oil
from the tank, excavating, and removing the UST, transporting the residual fuel and UST
off-site for proper disposal, recording a NRP on the subject property with land use
restrictions at the Guilford County Register of Deeds and completing the required public
notification.

Final Incident Closure Letter – 112 Green Acres Lane – NCDEQ Incident # 48731 2
Pyramid Environmental & Engineering, P.C. 04/06/23

Removal of Heating Oil UST
On March 9, 2023, one 550-gallon heating oil UST was removed and permanently closed
at the site by Fulp Environmental. Prior to removing the UST, 35 gallons of residual fuel
was removed from the tank. The residual fuel and UST were transported off-site for
proper disposal by Fulp Environmental. Copies of the Certificates of Disposal for the
UST and residual liquid are included in Attachment C.
Water Supply Well Abandonment
On March 10, 2023, the on-site inactive water supply well was properly abandoned by
Pyramid NC Certified Driller Timothy D. Leatherman (NC License #2888-A). The water
supply well was abandoned using a mixture of 3,000-psi cement and pea gravel in
accordance with the NCDEQ, Division of Water Resources well abandonment guidelines
and Guilford County Health Department requirements. The Guilford County well
inspector was on site during the well abandonment and approved the work. Copies of the
Well Abandonment Records and Well Abandonment Detail diagram are included in
Attachment D.
Notice of Residual Petroleum
On March 15, 2023, a Notice of Residual Petroleum was recorded for the subject site at
the Guilford County Register of Deeds in Deed Book R 8709, Pages 2541-2544. The
NRP includes groundwater and soil restrictions. A copy of the recorded NRP is included
as Attachment E.
Public Notification
On March 20, 2023, public notification letters were prepared by Pyramid and mailed to
the Greensboro Mayor, Greensboro City Manager, Guilford County Manager, Guilford
County Department of Public Health, and to the owners of all properties that are
adjoining or adjacent to the subject site. After a three-week waiting period, four signed
return receipt cards were received by Pyramid. Copies of the of the seven certified mail
receipts and four signed return receipt cards are included in Attachment F.
Incident Regulatory Closure
Having completed the activities required in the CNNFA letter dated March 16, 2023,
Pyramid, and William T. Johnson are requesting a No Further Action Determination for
the Leaking UST incident. If you have any questions or comments, please contact me at
[phone] – Ext. 128.

Risk-based Assessment and Corrective Action for
Petroleum Underground Storage Tanks

Johnston Property
112 Green Acres Lane
Greensboro, Guilford County
Incident Number (if applicable): 48731
Risk Classification: Low
Ranking: L60D

Dear Mr. Johnston:

Information received by the UST Section, Division of Waste Management, Winston-Salem Regional Office
on October 24, 2022 and the Notice of Residual Petroleum received on March 15, 2023 have been reviewed.
The review indicates that soil and groundwater contamination meet the cleanup requirements for a low-risk
noncommercial site under Title 15A NCAC 2L .0202 and .0400, as modified by Session Law 2015-241,
but contamination exceeds the limits allowed for unrestricted closure of a site.

The UST Section determines the subject incident to be eligible conditionally for no further action status.
However, final approval of no further action status is contingent on the filing of the approved NRP with the
Register of Deeds in the county in which the release is located, verified by the receipt of a certified copy of
the filed NRP by this office; and on receipt of confirmation that public notice requirements have been
completed, as described in the following paragraphs.

Be advised that, as contamination may exceed the groundwater quality standards established in Title 15A
NCAC 2L .0202, groundwater within the area where contamination is present or is expected to migrate is
not suitable for use as a water supply. Be advised that as soil contamination may exceed the residential
MSCCs, the property containing the soil contamination is suitable only for restricted residential use
("residential" being inclusive of, but not limited to, private houses, apartment complexes, schools, nursing
homes, parks, recreation areas and day care centers), as stipulated in the Notice of Residual Petroleum
(attached).

As groundwater contamination may exceed the groundwater quality standards established in Title 15A
NCAC 2L .0202, and soil contamination may exceed the residential MSCCs, pursuant to NCGS 143B-
279.9 and 143B-279.11, you must file the approved Notice of Residual Petroleum with the Register of
Page 2 of 2

Deeds in the county in which the release is located and submit a certified copy to the UST Section within
30 days of receipt of this letter.

As groundwater contamination may exceed the groundwater quality standards established in Title 15A
NCAC 2L .0202, and soil contamination may exceed the lower of the residential or soil-to-groundwater
MSCCs, public notice in accordance with 15A NCAC 2L .0409(b) also is required. Thus, within 30 days
of receipt of this letter, a copy of the letter must be provided by certified mail, or by posting in a prominent
place, if certified mail is impractical, to the local health director, the chief administrative officer of each
political jurisdiction in which the contamination occurs, all property owners and occupants within or
contiguous to the area containing contamination, and all property owners and occupants within or
contiguous to the area where the contamination is expected to migrate. Within 60 days of receiving this
letter, this office must be provided with proof of receipt of the copy of the letter or of refusal by the
addressee to accept delivery of the copy of the letter or with a description of the manner in which the letter
was posted. Interested parties may examine the incident file by contacting this regional office and may
submit comments on the site to the regional office at the address or telephone number listed below.

If you have any questions regarding the actions that must be taken or the rules mentioned in this letter,
please contact Jordan Lerew at the Guilford County Department of Health and Human Services, 400 W.
Market Street, Suite 300, Greensboro, NC 27401 or [phone].

This conditional No Further Action determination will not become valid until the UST Section
receives a certified copy of the Notice of Residual Petroleum which is filed with the Register of Deeds
and until public notice requirements are completed.

Sincerely,

James W. Brown

On 10/19/2022, Pyramid installed two hand auger soil borings adjacent to a 550-gallon heating oil
UST at the subject property. Petroleum odor was detected at 7 feet in the soil boring (SB-2)
closest to the fill pipe. Sample SB-2-7' was prepared in a container supplied by Red Lab and
shipped via FedEx Ground to the lab in Wilmington for analysis. The lab results indicate 1,140
mg/kg GRO and 13,501 DRO, which exceed the NC DEQ reportable limits for GRO (50 mg/kg)
and DRO (100 mg/kg).

Definitions of Sources
Tank: means the tank that stores the product and is part of the underground storage tank system
Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end-use equipment (Vent, vapor recovery, or fill
lines are excluded.)
Dispenser:includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above
the shear valve)
Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that
connects the submersible turbine pump to the tank
Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor
recovery lines, and fill lines)
Unknown: identifies releases for which the source has not been determined
Definitions of Causes
Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser)
Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser)
Physical or Mechanical Damage:use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken
components, and components that have changed dimension)
Corrosion:use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust)
Installation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly
Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells)
Unknown: use when the cause has not been determined
An inactive supply well is buried in the front yard of the house. The
current property owner has never used the well and does not know if
it has been properly abandoned. Pyramid will attempt to locate the
well and properly abandon it as part of the incident closure work.
