<p>CARB prepared a Preliminary Draft Staff Proposal-Recommended Approaches for Setting Thresholds for greenhouse gases (GHGs) under California Environmental Quality Act (CEQA), released in October 2008, and the subsequent public workshop, held in December 2008. This project involved working closely with CARB staff on rolling out actions associated with Assembly Bill (AB) 32, understanding CARB&rsquo;s process on these types of projects, and working in a time conscience manner to ensure all deadlines where met. Specific project tasks included the evaluation of performance standards for various emissions sectors (e.g., construction, energy, water, waste, commercial, industrial, and transportation); threshold application analyses in terms of effectiveness, feasibility, and emissions capture; and development of substantial evidence that the recommended approaches would sufficiently mitigate new project-generated emissions. Specifically, this work explored the number, types, and size of projects that would fall above and below certain emissions levels (e.g., potential thresholds) and how the application thereof to projects subject to CEQA would affect estimated GHG emissions. A segment of this work also required extensive research on how CEQA (in particular categorical exemptions) was applied in various counties across the State to support the approach that projects exempt under existing statutory or categorical exemptions could be presumed less than significant with regards to impacts related to climate change.</p>
