Montana Environmental Trust Group
The American Smelting and Refining Company (ASARCO) declared bankruptcy in 2005, and under a 2009 court-approved settlement, three custodial trusts were created to address environmental cleanup at former ASARCO sites across 13 states. The Montana Environmental Custodial Trust took title to the 4 Montana sites, which together contain ±4,265 acres, and received nearly $138 million to pay for cleanup, restoration, and revitalization.
Greenfield Environmental Trust Group, Inc. was chosen as Trustee of the Montana Environmental Custodial Trust, and Greenfield’s East Helena, Montana-based subsidiary Montana Environmental Trust Group (METG) was appointed as the Federal District Court Trustee. METG’s primary role is to protect human health and the environment in partnership with beneficiaries—the United States and State of Montana—as well as community stakeholders.
