Closed Hazardous Waste Site #: 94-1679 (“Rosetti Real Estate” a.k.a. “Northern Petroleum”)
UST Facility ID #: 8649819

Property #27 was formerly listed on the Vermont Active Hazardous Waste Site listing (Site #94-1679) and is now closed. The property was referred as a hazardous waste site in December of 1994 due to subsurface petroleum impact detected during the removal of diesel and No. 2 fuel oil underground storage tanks (USTs) [1]. The following USTs were removed from the property on 17 November 1994 [2]:

The UST closure report stated that the tanks, owned previously by Northland Petroleum, were taken out of service in December 1993 [2]. Concentrations of volatile organic compounds were detected by field screening methods above State-accepted guidelines in soils surrounding each of the USTs (which were located in close proximity to one another). Based upon the absence of holes in the USTs, and their general condition upon removal, it was surmised that subsurface petroleum impacts were possibly due to periodic spills and overfills over the 20 plus years of tank use at the property [2]. Removed soils were replaced in the excavation.

The UST closure report also notes that a soil stockpile on the property, which derived from a “tank that had been pulled many years ago” and was reported to have been a gasoline tank, was thinspread on 17 November 1994 with permission from the VTDEC [2]. No elevated concentrations of petroleum-related constituents were detected by field screening methods in these soils upon thin-spreading [2].

A follow-on investigation was performed at the site in April 1995 to determine the degree and extent of petroleum impacts and characterize potential environmental risk to area receptors [3]. The investigation involved a soil vapor survey and limited groundwater sampling. Soil vapor samples were extracted from clay soils in six vapor points advanced in the former vicinity of the USTs. On-site field screening results indicated no elevated concentrations of petroleum-related constituents. One discrete groundwater sample was collected from a 10-foot driven sample probe in the direct vicinity of the former USTs. Laboratory analysis of this grab groundwater sample indicated no detectable concentrations of targeted petroleum-related constituents [3]. Based on these results, the VTDEC granted Sites Management Activity Completed (SMAC) status to this site in September of 1995, and removed it from the Active Hazardous Waste Site listing [4].

Adjacent Hazardous Waste Site (Property #28)
Shallow soils and groundwater at Property #27 appear also to have been impacted by a petroleum release on an adjacent site to the southwest: 175 Lakeside, VTDEC Active Hazardous Waste Site #91-1069 (see Environmental Status, Property #28). Groundwater monitoring is ongoing at this adjacent site. Concentrations of petroleum constituents in groundwater are relatively low, but exceed Vermont Groundwater Enforcement Standards (5, 6).

<<< Residual petroleum impact>>> likely exists on the 189 Lakeside property in shallow soils from surface to approximately 10 feet below grade. Potential environmental or business risks would be identified and characterized during the process of a Phase 1 Environmental Site Assessment. Some environmental risks are mitigated by the fact that this given this property is serviced by municipal water and not an on-site groundwater or surface water supply.
