4.3 Environmental Site History
The Distillery Redevelopment | East Second Street | South Boston
The property is located in a commercial/residential area of South Boston. The
property and surrounding properties have had industrial/commercial uses for well
over 100 years. The neighborhood, including portions of the property, were part
of a manufactured gas plant that operated from the 1890’s to the 1930’s. A
shipping channel also occupied the lower portion of the property along First
Street.
The property has three Release Tracking Numbers (RTN) associated with it. The
response actions to the releases have been conducted under the Massachusetts
Contingency Plan (310 CMR 40.0000).
RTN 3 – 11965
This petroleum release is associated with the former No.6 fuel oil tanks. In
October 1995, a 9,000 gallon underground ground storage tank was removed from
the property. During a Phase I assessment, elevated levels of total petroleum
hydrocarbons were detected above reportable concentrations. A Phase II
Comprehensive Site assessment was conducted. A Release Abatement Measure
consisting of bioremediation was also undertaken to reduce the levels of
petroleum contamination in the soil. A Method III Risk assessment confirmed that
the petroleum contamination was low enough to conclude that a Condition of No
Significant Risk had been obtained at the site. An Activity and Use Limitation
was submitted that provided notice on the deed that soils below 9 feet from grade
were to be left undisturbed unless proper oversight was obtained by a Licensed
Site Professional. A Response Action Completion Report was prepared for RTN
3-11965 and submitted to the Massachusetts Department of Environmental
Protection in February, 1999.
RTN 3 – 18069

contamination as described above, elevated levels of polyaromatic hydrocarbons
