Cleanups in Wyoming


Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these properties protects the environment, reduces blight, and takes development pressures off green spaces and working lands.

A Target Brownfields Assessment (TBA) is a free service the EPA Region 8 Brownfields Team provides to communities to support their eligible brownfields projects. These services include brownfield inventories, area-wide planning, site environmental assessments and investigations, and site cleanup planning.
