2008 Climate Action Team (CAT)

Implementation Working Group (IWG)
State Environmental Policy Act (SEPA)

The goal of the SEPA IWG is to develop recommendations to ensure that consideration of climate change is included in the State Environmental Policy Act (SEPA). The SEPA IWG will prepare recommendations on changes to SEPA rules, guidance and/or environmental review documents to provide clarity and predictability to project proponents and administering agencies regarding how climate change is to be addressed through the environmental review process. The SEPA IWG has divided its work into three activity areas:

  • Work Area #1 - Measurement and Disclosure: This work area will focus on SEPA's traditional processes for identifying, measuring, and reporting environmental impacts and how they will apply to climate change impacts.
  • Work Area #2 - Mitigation and Adaptation: This work area will focus on the use of SEPA by local governments and agencies to consider climate change mitigation and adaptation issues.
  • Work Area #3: Leveraging SEPA: This work area will focus on leveraging SEPA to promote "climate friendly" development.

Meeting Summary
Meeting Documents:

  • Agenda
  • Summary of SEPA IWG "Bucket 3": A document authored by the Bucket 3 group that summarizes ideas for SEPA incentives and disincentives to encourage climate friendly development. The SEPA IWG will discuss these ideas and decide which to further pursue as a group.
  • Linking Threshold Determination to Statewide GHG Goals : Two documents describe and illustrate draft policy King County is considering which could link its significance standard to the statewide greenhouse gas reduction requirements. The question of how to make the linkage between SEPA threshold determination and Washington State’s goals came up at the last SEPA meeting; this is a possible rationale King County is considering.
  • Project Emission Examples for Threshold Discussion: This document lists the estimated greenhouse gas emissions from a variety of projects and shows the volume of “allowable” emissions under various % reduction scenarios. It is intended to offer some real world examples of what percent or volume-based approaches to the significant standard could look like.
