Planning and Environmental Linkages (PEL) is a process approach to transportation decision-making that considers environmental, historical, cultural, and feasibility issues early in the process. Public engagement allows the community to be part of the process and guides the project team to acceptable decisions. The information analysis and products developed during the PEL study are then used to inform the formal federal National Environmental Policy Act (NEPA) environmental review process.

Environmental Assessment (EA) is required when the significance of the environmental impacts are uncertain. The purpose of this process is to clarify any uncertainty and document the finding. If no significant impacts are found, the process is concluded with a Finding of No Significant Impact (FONSI). However, if there are significant impacts, an Environmental Impact Statement (EIS) is then completed.

Guidelines ensure the public has ample opportunity to effectively participate in transportation decision-making. They also ensure that the development of transportation programs and projects in Michigan support federal, state and local goals and objectives.
