Dear Mr. Mao:
Subject: Monitoring Well Abandonment
Ryder Greensboro LC 0134
217 Atwell Avenue
Greensboro, Guilford County, North Carolina
CEC Project 190-913
Ryder Truck Rental, Inc. (Ryder) operates a fleet maintenance facility at 217 Atwell Avenue in
Greensboro, Guilford County, North Carolina (Subject Property). Two Underground Storage
Tank (UST) systems, a diesel and a used oil, were closed at this facility during 2019. Because
groundwater was encountered during the closure activities, and in accordance with the North
Carolina Department of Environmental Quality (NC DEQ) UST regulations, two monitoring wells,
MW-1 and MW-2, were installed. Monitoring well MW-1 was installed adjacent to the diesel
UST basin and monitoring well MW-2 was installed adjacent to the used oil UST basin. The
approximate locations of the monitoring wells are shown on Figure 1. A UST closure report was
submitted to the NC DEQ on September 3, 2020. The NC DEQ issued a No Further Action (NFA)
letter for the diesel UST system on September 21, 2020. Following a limited background soil
assessment for chromium, the NC DEQ issued a NFA letter for the used oil UST system on
January 28, 2022.
Based on the NFA letters issued for each of the UST system closures, the two monitoring wells at
the Subject Property were abandoned on June 9, 2022. Well abandonment activities were
performed by a licensed North Carolina well driller and in accordance with the Title 15A North
Carolina Administrative Code (NCAC) 02C. A copy of the Well Abandonment Record (GW-30
Form) and photo documentation are provided as attachments.
