PennDOT Transportation Projects are divided into three complexity levels, as shown in Tables 2.1, Typical Non-Complex (Minor) Projects; 2.2, Typical Moderately Complex Projects; and 2.3, Typical Most Complex (Major) Projects of DM1, which are attached below.

While Tables 2.1A, 2.2A, and 2.3A provide some guidance on the appropriate level of environmental document, it is important to note that project complexity levels are not always good indicators of the environmental document level. Some projects that are complex from a design standpoint may not be environmentally complicated (i.e. few environmental issues and/or impacts) and therefore might require a Categorical Exclusion (CE) instead of an Environmental Assessment (EA) or Environmental Impact Statement (EIS). Similarly, a non-complex (minor) project might be very challenging from an environmental standpoint (i.e. numerous environmental issues, potential for significant effects, or substantial public controversy) and could require a higher environmental document level than a CE. Decisions on the appropriate level of environmental document for a project should be made by the District Environmental Manager at the Scoping Field View in coordination with the Project Team, including PennDOT Central Office and FHWA as necessary.
