The Town of Dubois contracted Trihydro to provide technical assistance for remedy evaluation and implementation for asbestos-containing material (ACM) at a former wild game processing facility. The property consisted of the main building constructed in 1920 and used for various commercial purposes as well as two sheds. An Asbestos Survey and Assessment was conducted in 2020 and identified friable and non-friable asbestos. Subsequently, a Phase I Environmental Site Assessment (ESA) identified several environmental concerns, including ACM and potentially hazardous building materials related to the age of construction (e.g. lead-based paint, fluorescent light fixtures with possible polychlorinated biphenyls-containing ballasts, and mercury-containing ampule switches in thermostats). Trihydro conducted a third-party review of the Phase I ESA and Asbestos Survey to confirm environmental issues and assess remediation needs.
The Town of Dubois enrolled the site in the Wyoming Department of Environmental Quality (WDEQ) Voluntary Remediation Program (VRP) to address the environmental conditions. Subsequently, the Town of Dubois applied for and received funding from the Wyoming Business Council (WBC) through a United States Department of Environmental Quality (EPA) Revolving Loan Fund (RLF) to abate ACM and other hazardous building materials before building demolition.
Trihydro prepared an Analysis of Brownfields Cleanup Alternatives (ABCA) Report for the Town of Dubois, which was submitted to the WDEQ and EPA Region 8. The ABCA recommended ACM and hazardous materials abatement and building demolition and disposal, which was approved by WDEQ. Trihydro assisted with remedy implementation by developing asbestos bid specifications and providing environmental oversight of the abatement activities, including air sampling and adherence to bid specification requirements. Trihydro also prepared a Remedy Complete Report for the WDEQ VRP and EPA, which included documenting site activities and a request for site closure.
Through an understanding of the regulatory process and funding opportunities, Trihydro assisted the Town of Dubois with the abatement of ACM and hazardous materials at a former game processing facility in downtown Dubois. The project included a multi-stage environmental assessment and clean-up process, transforming a contaminated brownfield site into usable space for future redevelopment.
