Department of Energy and Environmental Protection officials responded to an Eversource substation in New London Monday afternoon after 500 gallons of mineral oil leaked from a mobile transformer, according to DEEP.
The mineral oil escaped from a leak in a hose from he transformer, which held 3,250 gallons total, according to Dennis Schain of DEEP.
An environmental contractor responded to clean up the mineral oil leak and remove "an impacted trap rock and soil" under DEEP's supervision, Schain said.
