Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
14 Cal. Code of Regs. §§ 15301, 15302
Reasons for Exemption
The MASCOTS plan is exempt from the California Environmental Quality Act because it involves a change to regional and subregional transit service on existing highways already in use, namely the U.S. Highway 101 Corridor in Marin and Sonoma Counties. This project will use the same buses already in use and will not result in any significant change in the number of GGT bus service hours or bus miles traveled. While the project may result in a small number of existing riders resorting to other forms of transportation, the project will result in a net increase in GGT ridership
along the modified routes. The project, therefore, has no reasonable possibility of a significant effect on the environment. The project also involves no unusual circumstances, sensitive habitat, or possibility of cumulative impacts that could result in the possibility of a significant effect on the environment.
