Notice of Exemption
Exempt Status
Statutory Exemption
Type, Section or Code
Sections 15262, 15061(b)(3)
Reasons for Exemption
The MPAH is a long-range planning document that describes existing infrastructure and conceptual future transportation facilities within Orange County. OCTA does not commit itself or any other public agency to approve, adopt, or fund any MPAH related
projects by including those facilities on the MPAH. In order for projects on the MPAH to move forward, they must be approved by the appropriate lead agency based on detailed project applications and environmental review. Similarly, deletion of a facility from the MPAH does not preclude a local jurisdiction from implementing the facility. As a result, amendments to the MPAH do not have any reasonably foreseeable environmental consequences or commit OCTA, or any other public agency, to a definite course of action.
Amendments to the MPAH, therefore, are not "projects" subject to CEQA, and approval of an amendment to the MPAH does not constitute project "approval" for CEQA purposes. (Public Resources Code§ 21065; CEQA Guidelines§ 15378(a); CEQA Guidelines§ 15352(a)). If anything, the MPAH is a government funding mechanism expressly excluded from the definition of "project." (CEQA Guidelines§ 15378(b)(4).) Among other things, voluntary consistency with the minimum capacity reflected on the MPAH establishes eligibility for Measure M2 funding.
If amendments to the MPAH were to be considered "projects", the amendments would qualify for at least two exemptions from CEQA review. First, the MPAH is a planning and feasibility study. As explained above, neither the MPAH nor amendments to the MPAH have a legally binding effect. Therefore, amendments to the MPAH fall within CEQA's statutory exemption for planning and feasibility studies (CEQA Guidelines§ 15262.) Second, for all of the foregoing reasons, it can be seen with certainty that there is no possibility that amendments to the MPAH may have a significant effect on the environment. Amendments to the MPAH therefore fall within CEQA's
"common sense" exemption (CEQA Guidelines§ 15061 (b)(3)).
