Terraphase conducts bi-weekly asbestos-containing material (ACM) and lead-based paint (LBP) inspections for a California utility client’s decommissioned substation equipment. The equipment is moved by the utility client to its central facility, where Terraphase inspects and collects bulk samples to determine if ACMs and/or LBPs are present before the equipment is abated/remediated and eventually recycled or disposed of by the utility client.

Scope of Services

The scope of work requires that a high volume of equipment be assessed, analytical results be interpreted and tabulated, and a survey report be submitted to the utility client so that the regulated materials can be abated within a two-week time frame. Terraphase refers to historical sampling results prior to collecting the bulk samples to minimize unnecessary sampling. Approximately 35 bulk samples are collected during each sampling event to address data gaps. Sampled items include Transite™ panels, braided wire wrap, wire putty, insulation, coils, and switch plates. The inspections are conducted in accordance with local air quality management district regulations. Terraphase is also responsible for providing perimeter air monitoring spot checks during the abatement activities. The spot checks are conducted to confirm that the abatement contractor’s work practices and engineering controls are adequate, and that utility client staff are not exposed to excessive airborne fibers. Air monitoring results are included with the survey reports.
