A detailed environmental analysis was conducted and potential impacts associated with the No Action Alternative and Preferred Alternative were documented. Mitigation measures to be implemented with the Preferred Alternative were identified in the EA. No significant impacts to the environment were identified during the course of this study.
Colorado could pursue fees based on actual travel as an alternative to the fuel tax. Revenues from mileage-based user fees (MBUF) would not vary based on fleet fuel consumption and would instead return revenue in proportion to use of the roadway network. Too many operational and technological questions remain unanswered, and must be tested and evaluated before the state would be ready to commit to a statewide implementation of this strategy.
The purpose of this Manual is to provide guidance on preparing and processing documents that comply with NEPA and other applicable state and federal environmental laws affecting transportation projects in Colorado. This Manual provides references and links to related federal and state laws, executive orders, regulations, and policies. It also provides "best practice" examples for various compliance processes where appropriate. It is intended that CDOT staff, local agency representatives, and consultants use this Manual to implement NEPA in an effective manner, producing more consistent, improved environmental documents that decision-makers may use to make well-informed transportation decisions.
