Greenhouse Gases and CEQA

District Environmental Review Guidelines Addressing Greenhouse Gas Emissions under the California Environmental Quality Act (CEQA)

The District has updated its Environmental Review Guidelines to include guidance for evaluating the significance of the impacts of greenhouse gas emissions from new or modified stationary sources. Stationary source projects include land uses with processes and equipment that require a District permit to operate, such as oil and gas facilities, landfills, and facilities with large combustion devices.


The District’s Environmental Review Guidelines provide procedures for the District and other agencies to use when reviewing projects under CEQA. The District’s Guidelines are applied directly to projects for which the District is the lead agency under CEQA, including District permits, rules, and plans. The District’s Guidelines document, first adopted by the Board in 1995, was last revised in 2000. Starting in 2010, the state’s CEQA guidelines have included a framework for addressing climate change impacts under CEQA. This project will consider the latest information on greenhouse gases and CEQA.  For more information on the District’s Land Use and CEQA review activities see Land Use and CEQA.


The California Office of Planning & Research (OPR) developed amendments to the CEQA Guidelines, which were adopted by the California Natural Resources Agency on December 30, 2009 and became effective on March 18, 2010. These amendments establish a framework for including global climate change impacts in the CEQA process, and include revisions to the Environmental Checklist Form (Appendix G) as well as to the Energy Conservation appendix (Appendix F).  A section (§15064.4) was added that provides an approach to assessing impacts from greenhouse gases.

A lead agency is required to determine the significance of impacts from greenhouse gases but is given discretion to:

  • Use a model or methodology to quantify greenhouse gases and decide which model or methodology to use,
  • Rely on a qualitative analysis or performance-based standards.

When assessing the significance of greenhouse gas impacts, a lead agency can consider:

  • Whether project emissions exceed a threshold of significance that lead agency has applied to the project,
  • If the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of greenhouse gases.

Public Workshops, Outreach, and Process Overview

A special meeting of of the District Board of Directors was held on April 30, 2015 to consider adoption of a GHG threshold for CEQA and revisions to the Environmental Review Guidelines.

The District held a public workshop and District Community Advisory Council (CAC) meeting on March 25, 2015. The District presented two threshold options for setting project significance. Following the public workshop, the CAC considered the options presented. A majority of the members voted to recommend the AB 32 Consistency threshold option for adoption by the District Board of Directors. View:

Notices about the March 25 workshop were placed in local media sources in the county and emailed to subscribers on our [email protected] email list.
