Pre-Characterization Assessments of Electrical Substations

Since 2016, Stone Environmental has supported Vermont Electric Power Company (VELCO) with pre-characterization assessments of their electrical substations throughout the State of Vermont. These assessments investigate the degree and extent of potential contaminants in substation soil and building materials from spills from oil-containing electrical equipment, use of asbestos containing materials, or other potential contaminant sources. These investigations support VELCO’s Section 248 notifications to the Public Utility Commission prior to electrical substation renovations, which have included entire substation rebuilds.
