When is this applicable for your project?

Environmental Clearance is required for every project, adhering to the National Environmental Policy Act (NEPA). For additional details, use the links  on the right to the Environmental Program website and/or discuss with your resource specialist. NEPA took effect January 1, 1970, and is implemented by the Federal Council on Environmental Quality. This is a law enabling transportation officials to make project decisions that balance environmental factors with engineering and transportation needs. NEPA requires a project to follow one of three paths to obtain environmental clearance: Categorical Exclusion, Environmental Assessment, or Environmental Impact Statement. A majority of our projects are Categorical Exclusions, which culminate in a signed CDOT Form 128 before Advertisement.

What are the Roles and Responsibilities in the arena?

The Region Program Environmental Manager (RPEM) initiates Form 128 to document the analysis required and completed for the individual environmental resources.  More detail on each of the individual environmental resource areas listed below is in the “Clearance Processes for Environmental Resources” table in the “Manuals and Other References” box on the right side of this page. REPM and in some cases, FHWA concurrence is required to achieve Environmental Clearance, which is required before a project can be advertised.
