On this page you will find a chronological listing of Environmental Assessments produced by Interior Region 7 – Upper Colorado Basin. An alphabetical listing is available here.

Environmental Assessments and associated documents are generated to fulfill the requirements of the National Environmental Policy Act. Environmental Assessments are used to determine if significant environmental impacts would occur as a result of a Reclamation action or a Reclamation funded action.

An Environmental Assessments is a concise public document that serves to provide:

  • sufficient evidence and analysis regarding the significance of environmental impacts of the proposed action
  • alternatives to that proposal to aid in decision-making when there is an unresolved conflict in the use of resources

Reclamation shall prepare an environmental assessment for a proposed action that is not likely to have significant effects or when the significance of the effects is unknown unless the Reclamation finds that a categorical exclusion is applicable or has decided to prepare an environmental impact statement.
