An Environmental Assessment (EA) is a comprehensive study that evaluates potential impacts, both positive and negative, of alternative actions under consideration. An EA is being prepared for US 24 West to provide decision makers at the Federal Highway Administration and the Colorado Department of Transportation with information on no-action and build alternatives, including potential impacts to the built, natural, and social environments that may occur within the project study area. The EA will help agency officials decide which project alternative to approve based on the environmental consequences of each alternative.

The EA for US 24 West will evaluate potential impacts to resources such as right of way, air quality, noise, cultural resources, hazardous waste, low income and minority populations, neighborhoods and land use. Proposed mitigation measures to minimize or avoid potential impacts will be identified in the EA.

If there are no significant impacts from the proposed action, a Finding of No Significant Impact (FONSI) is prepared. If the EA indicates significant impacts will occur from the proposed action, an Environmental Impact Statement (EIS) is prepared. The EA is being prepared in compliance with the National Environmental Policy Act (NEPA) of 1969.
