Re: Petroleum Release from Former Non -Commercial, Non -Regulated Heating
Oil Underground Storage Tank at 4043 Arborway in Charlotte, North Carolina
NCDEQ Incident No. 40989
Project No. 842-01
Ms. Beverly and Mr. Storosh:
Harmon Environmental, PA has been retained by Mr. Michael Schulte, the owner of the property at
4043 Arborway to assist in addressing the petroleum release from the former non-commercial, non -
regulated heating oil tank recently removed from the site. On February 10, 2020 the Charlotte -
Mecklenburg Stormwater Services issued a Notice of Violation letter outlining the discovery of a
petroleum -release from the referenced property. On February 11, 2020 the North Carolina
Department of Environmental Quality issued Notice of Regulator Requirements letter. As indicated
in these correspondences on February 9, 2020 a petroleum -release was documented at 4043
Arborway. This release apparently originated from a formerly undocumented underground heating
oil tank. Storm water apparently flooded the former underground storage tank basin, floating
petroleum into the surface water drainage system. The impacted storm water was transported via
sub -grade piping to a surface ditch located on 4033 Arborway and subsequently flowing across the
back yard of 4040 Abington Road before entering a subgrade pipe ad discharging into McMullen
Creek in the backyard of 4042 Abington Road.
On February 9, 2020 Carolina Environmental Response Team (CERT) addressed the subgrade
piping from 4040 Abington Road to McMullen Creek. Following cleaning the pipe, hydrophobic
adsorbent booms were installed at the inlet and outlet of this pipe. On February 10, 2020 DeBruhl
Environmental Excavating, Inc. removed the former underground storage tank from 4043 Arborway.
Mr. Schulte is in the process of retaining DeBruhl Environmental Excavating, Inc. to excavate and
remediate the petroleum -impacted soil from the drainage feature on 4033 Arborway and 4040
Abington Road. In preparation for these activities, Harmon Environmental, PA has prepared and
submitted Access Agreements to both property owners. Following approval of these access
agreements, sub -grade utilities will be located.

Ms. Trudy Beverly, P.G. and Mr. Matthew Storosh.

When weather permits, DeBruhl Environmental Excavating, Inc. personnel will visit the site and
excavate petroleum -impacted soil from the two properties. As excavated, Harmon Environmental,
PA personnel will screen samples from the bottom and side walls of the excavations, for the
presence of petroleum vapors using a MultiRae Organic Vapor Analyzer, or equivalent, calibrated to
an isobutylene standard. Following completion of the excavation activities, up to five samples will
be collected for laboratory analysis. These samples will be analyzed for the presence of volatile
organic compounds by SW-846 Method 826013; Semi -volatile organic compounds by SW-846-
Method 8270D BN/A and; volatile and extractable petroleum compounds by Massachusetts
Methods.
If feasible, the tank basin will be excavated in conjunction with these activities. In the event further
excavation in the vicinity of the former tank is not viable, samples will be collected to assist in
preparing a Notice of Residual Petroleum. Upon receipt of the analytical results, an Initial
Abatement Report will be completed and submitted.
We will keep you appraised of the progress on this project. Please call or email if you have any
questions or require any additional information.
Sincerely,
Harmon Environmental, PA
