and greenhouse gas pollutants have been given relatively little or no consideration in
environmental review documents. This situation is changing rapidly. Many state and
local governments both here in Washington state and around the country are beginning to
develop policies, regulations, and guidance on how, where, and when to address climate
change in their environmental review processes. Some are doing so because their failure
to address climate change was challenged in court as contrary to SEPA-like statutes.
Others are simply recognizing the importance and value of incorporating climate change
considerations into governmental decision-making, resource and development planning,
and permitting and approval.
To date, the Port has not adopted any policies related to the assessment of GHG
emissions and climate change under SEPA. However, in the Port‟s recent SEPA
determinations considerations or evaluations, we have already been estimating quantities
of GHG emissions as part of our SEPA review of proposed actions, as have other local
jurisdictions such as the City of Seattle and King County.
Staff believes it is in the best interest of the Port to act now to clarify how climate
considerations should be incorporated into its SEPA review when it is acting as a “lead
agency.” Towards that end, the proposed SEPA climate change policies address the
following:
Clarifying that the Port will consider GHG emissions and the effect of changes in
climate on proposed actions as a mandatory component of SEPA environmental
review;
Requiring the identification and calculation of GHG emissions associated with a
project proposal, within reasonable spatial and temporal boundaries, as part of
SEPA environmental review;
Encouraging the identification of mitigation measures that the Port may
voluntarily incorporate to reduce a project‟s GHG emissions below a level of
significance or to reduce the Port‟s GHG emission baseline;
Acknowledging that when making the “threshold determination” under SEPA
there is no uniform standard for determining the “significance” of a project‟s
GHG emissions impacts;
Acknowledging that any decision by the Port as to whether there is an adverse
environmental impact from a proposal will be made on a case-by-case basis;
Identifying factors that may be considered by the Port when determining whether
a project‟s GHG emissions constitute a “significant” impact; and
Considering the effects of climate change on projects that are designed for long-
term utility and located in areas that are considered vulnerable to specific effects
of climate change (such as increasing sea level or ecological change) within the
project‟s timeframe.
