The San Joaquin Valley is currently designated as nonattainment with respect to Federal air quality standards for ozone and PM 2.5; and has a maintenance plan for PM-10. As Kern County’s transportation planning agency, Kern COG is responsible for demonstrating that transportation plans and programs satisfy the requirements of the Clean Air Act.

Project-Level Conformity (Hot-spot Analysis) process involves scheduling a combined interagency call and public meeting to review each non-exempt project and PowerPoint presentation associated with each project sponsor. The Meeting Agenda, Project Checklist and Power point Presentation need to be post on Kern COG website 2 weeks before the virtual meeting.  This new process allows public and agency partners, including Caltrans, FHA, and EPA, to ask project-related questions directly and confirm determinations “live” during the conference to determine if the project is not a Project of Air Quality Concern (POAQC). Final documents will be uploaded on Kern COG’s website for public review and comments.

Each MPO is responsible for posting project information on their respective websites, responding to public comments, and organizing Interagency Consultation (IAC) calls that are open to public attendance.
