We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


In October of 1995, three underground storage tanks, piping, and distribution systems were removed. Petroleum impacted soil and groundwater was discovered during the tank removal. Presently, soil and groundwater downgradient of the former location of the storage tanks, piping, and distribution systems meets the Department's most stringent cleanup levels. The levels of benzene in soil and groundwater upgradient of the original source of contamination do not presently meet the Department's most stringent cleanup levels. F.K.A L55.210

7/1/2002 Update or Other Action Letter to forego gw sampling until Feb 2003 due to lack of money allocated for site soil excavation, treatment, and sampling. Amanda Dreyer
2/6/2003 Leaking Underground Storage Tank Corrective Action Underway Approved CAP, and approved that monitoring G9 and B13 can be taken out of the sampling suite Amanda Dreyer
5/10/2004 Leaking Underground Storage Tank Corrective Action Underway Approved revised corrective action plan submitted by Shannon & Wilson. Three new monitoring wells will be installed and sampled new the property boundary. Depending on sample results, ORC socks may be installed in the wells to assist with groundwater remediation. Scott Pexton
5/14/2004 Update or Other Action Pexton approved request from Shannon & Wilson to transport petroleum contaminated soil from the facility to Alaska Soil Recycling for thermal treatment. Scott Pexton
6/29/2004 Report or Workplan Review - Other DEC received Remedial Progress & Groundwater Sampling Report prepared by Shannon & Wilson with funding provided by UST Cleanup Grant #15245133. Scott Pexton
8/23/2004 Update or Other Action Letter sent to Kingston Peters requesting documentation to demonstrate that the contaminated soil removed was treated and disposed in accordance with the corective action plan.

10/1/2004 Update or Other Action On 10/1/04, DEC received from S&W: 1) 6/15/04 report from ASR showing 53.56T of pet. Soil was treated to Level A 2) request to transport 1 drum of soil from MW B15 to ASR. DEC on 10/1 approved the transportation request. Rich Sundet
10/1/2004 Long Term Monitoring Established Received Soil Boring and Groundwater Sampling Report. Three new wells were installed on the eastern edge of property to investigate whether an upgradient source of contamination exists. Benzene was detected at a level of approximately 0.01 mg/L in two of the three wells installed, which supports the argument for an upgradient source of contamination. Todd Blessing
1/26/2005 Conditional Closure Approved Record of Decision (ROD) submitted to responsible party. ROD states that there is benzene contamination remaining above the established cleanup levels in the soil and groundwater southeast of the former USTs, piping, and the fuel distribution systems. The remaining contamination is likely due to contaminant migration from adjacent properties. The low levels of benzene in soil and groundwater on the eastern portion of the property, which are only slightly above established cleanup levels, are expected to be treated over time via natural attenuation. As a result, the Department has determined that the levels of contaminants of concern at Tudor Car Wash pose no risk to human health or the environment. In November 2005 , well decommissioning report confirmed that on-site drinking water wells were decommissioned; Therefore, this site is closed effective December 2, 2005. Todd Blessing
1/26/2005 Institutional Control Record Established Once the Department is notified that the remaining monitor wells on the site are decommissioned, a site action will be entered on the Department’s database to reflect that the site is closed. Todd Blessing
