According to the U.S. EPA, a Brownfield is an industrial, commercial, and/or residential property or site which has been abandoned, idled, or underused, complicating development, redevelopment, or expansion because of actual or suspected environmental contamination.In 2015, the Tribe began a Brownfield program on the Reservation in order to inventory potential Brownfield sites and conduct investigations as needed.To implement this program, Tribal EPA staff work toward achieving “the four elements” of a Tribal response program:

  1. Timely Inventory of Brownfield Sites within Reservation boundaries.

  2. Oversight and enforcement authorities or other mechanisms and resources to protect human health.

  3. Mechanisms and resources to provide meaningful opportunities for public participation.

  4. Establishment of procedures for approval of a clean-up plan.
