PART ONE
AUTHORITY AND PURPOSE 
Section 1    Authority and Purpose 
Section 1.1   Authority 
This resolution is adopted as required by Chapter 197-11 Washington Administrative
Code (WAC) to implement the State Environmental Policy Act and the State
Environmental Policy Act Rules (Chapter 197-11 WAC). This resolution may be cited as
the "SEPA Rules", and "these rules" as used herein refers to this resolution. As required
in RCW 43.21C.095,  the SEPA Rules shall be given substantial deference in the
interpretation of SEPA. 
Section 1.2   Purpose 
The purpose of this resolution is to adopt the uniform requirements of Chapter 197-11
WAC for compliance with SEPA, with some modifications and additions relevant to Port
operations. Many sections of Chapter 197-11 WAC are adopted verbatim or nearly so.
Each provision adopted by reference in this resolution is found in the statewide rules, 
Chapter 197-11 WAC, and should therefore be used in conjunction with this resolution.
Additionally, this resolution provides guidance to Port of Seattle staff when the Port is
acting as a project proponent and to the POS responsible official when evaluating
proposals under the State Environmental Policy Act, Chapter 43.21C RCW, that: (1) are
likely to result in greenhouse gas emissions; and/or (2) may be impacted by the effects of
climate change.
Section 1.3   Previous SEPA Rules 
This resolution replaces previous SEPA Rules adopted by the Port,  including
resolutions 3028, 3211 and 3539. 
Section 1.4   Relationship to SEPA and Rules 
The provisions of this resolution, Chapter 197-11 WAC and the SEPA must be read
together as a whole in order to comply with the spirit and letter of the law. The Port
adopts by reference the purposes and policies of SEPA as set forth in RCW 43.21C.010
and 43.21C.020. 
Section 2    Application of SEPA
2.1    Application to Port Activities 
SEPA provides the framework for agencies like the Port to consider the environmental
consequences of a proposal before taking action.  SEPA review is required for any
proposal that involves a governmental "action" as defined in the SEPA Rules (WAC 197-
3

11-704), and is not categorically exempt (WAC 197-11-800 through 890). Project actions
involve an agency decision on a specific project, such as a construction project. 
Nonproject actions involve decisions on policies, plans, or programs such as the adoption
of a comprehensive plan. 
Section 2.2   Substantive SEPA Authority 
SEPA grants agencies the ability to condition or deny a proposal due to likely significant
adverse impacts identified in a SEPA document. To use SEPA substantive authority, the
Port must have adopted SEPA policies.  There are other federal, state and local
environmental laws besides SEPA, which apply to specific resources, such as land, air,
water, historic areas, wildlife, and health. These other laws may require studies or serve
as the basis for mitigating or denying a proposal. 
Section 2.3   Timing of SEPA Review 
SEPA supplements, or "overlays," the Port's regular planning and decision-making. The
exact nature and timing of the SEPA process can vary for each type of governmental 
action and or each individual proposal. 
Section 3    Policy for Carrying out SEPA 
Section 3.1   Adoption by Reference 
The state rule containing policies and goals for implementing SEPA as intended by the
legislature, WAC 197-11-030, is adopted by reference. 

PART TWO 
GENERAL REQUIREMENTS 
Section 4    General Requirements 
Section 4.1   Adoption by Reference 
This part covers the basic requirements that apply across-the-board to the SEPA process.
The state rules in WAC 197-11-040 through 100 are adopted by reference. These rules
cover the following areas: 
1.     Where to find the meaning of words and terminology used in this 
resolution and the SEPA process (definitions, WAC 197-11-040 and Part
8); 
2.     Who is responsible for SEPA compliance (lead agency, WAC 197-11-
050); 
3.     When the SEPA process occurs (timing, WAC 197-11-055); 
4.     What impacts are to be  analyzed in the review process (content of
environmental review, WAC 197-11-060); 
4

5.     What can or cannot be done while the environmental review is occurring
(limitations on actions during the SEPA process, WAC 197-11-070); 
6.     What to do in the face of uncertainty or lack of information (incomplete
or unavailable information, WAC 197-11-080); 
7.     What is considered part of the SEPA record (supporting documents, 
WAC 197-11-090); and 
8.     What information applicants can be required to provide (information
required of applicants, WAC 197-11-100). 
Section 5   SEPA Process at the Port 
Section 5.1   Lead Agency 
The agency in charge of carrying out SEPA's procedural requirements for a proposal is
the lead agency. A lead agency is selected for each particular proposal. The Port will
typically be the lead agency for its proposals and public projects, including projects
proposed by private parties or tenant; on Port properties. 
Section 5.2  Responsible Official 
The person or office at the lead agency in charge of SEPA compliance is called the
responsible official. The Port's responsible officials are: 
1.     Seaport Division: Linda Styrk, Managing Director, Seaport Division, 
Port of Seattle, P.O. Box 1209, Seattle, WA 98111. 
2.     Aviation Division: Elizabeth Leavitt, Director, Aviation 
Planning and Environmental Programs, Port of Seattle, 
P.O. Box 68727, Seattle, WA 98168. 
3.     Real Estate Division: The Seaport and Aviation Division Responsible 
Officials shall be responsible for SEPA compliance for the Real Estate 
Division. 
The Chief Executive Officer is authorized to designate responsible officials for the
Seaport, Aviation Divisions and any other division of the Port. 
Section 5.3   Delegation 
The responsible official may delegate his or her responsibilities under SEPA in writing to
another Port official with the concurrence of the Chief Executive Officer.


5

Section 5.4   SEPA Public Information 
The office that routinely handles SEPA matters at the Port is: 
Environmental Services 
P.O. Box 1209 
Seattle, WA 98111 
(206) 787 -3190 
sepa.p@portseattle.org 
Section 5.5   Retention of Documents and Copying Charges 
SEPA documents required by these rules shall be retained by the lead agency and made
available in accordance with Chapter 42.56 RCW. The Port shall make copies of any
environmental document available in accordance with Chapter 42.56 RCW, charging
only those costs allowed by Section 44-14-07001 of the Washington Administrative
Code. However, no charge shall be levied for circulation of documents to other agencies
as required by these rules. 
Section 5.6   Other Agencies 
When acting as the lead agency on a project, the Port may consult with other agencies as
required by Chapter 197-11 WAC and Chapter 43.21C RCW.  An agency that has 
authority to approve, veto, or finance all or part of a nonexempt proposal is referred to
under SEPA as an "agency with jurisdiction." An agency with a special expertise on the
environmental impacts involved in a proposal is called an "agency with environmental 
expertise".  "Consulted agency" means any agency with jurisdiction or expertise that is
requested by the lead agency to provide information during the SEPA process. The Port's
Environmental  Programs shall be responsible for coordinating and preparing 
environmental documents with these other agencies (also see Section 13 below). 
Section 5.7   Federal Coordination 
When acting as the Lead Agency on a project with a federal nexus, the Port will work
with federal agencies to the fullest extent possible to reduce duplication between the
National Environmental Policy Act (NEPA) and state and local requirements. The
responsible official shall make an effort to coordinate environmental review requirements
with applicable Federal agencies, including combining documents and holding joint
scoping, public meetings and hearings, as directed and encouraged by this resolution and
the Federal provision for eliminating duplication (40 CFR 1506.2). 
Section 6    Timing of the SEPA Process 
Section 6.1   Timing of Review 
Consistent with WAC 197-11-055(2)(b),  the responsible official  will decide the
appropriate time for reviewing the environmental impacts of Port proposals on a case-bycase
basis. 
Section 6.2  Compliance 
SEPA compliance is required for all Port projects and activities that meet the definition of
"action" in WAC 197-11-704. Except for those actions that are categorically exempt
6

under Part Nine  of these SEPA Rules and  WAC 197-11-305, a "final threshold
determination" or "final environmental impact statement", if required, shall be completed
prior to final Port approval of actions subject to SEPA.
Section 6.3   Committee Review 
If  the  Port  has  a  standing  committee  which  reviews  proposals  and  makes
recommendations to the Commission, the committee shall review any required final
threshold determination or final environmental impact statement prior to the committee's 
recommendation to the Commission on whether to approve the proposal. 
Section 6.4   Advisory Bodies 
To the extent the Port establishes a standing advisory committee or citizens advisory
committee on specific proposals or sites, the responsible official shall inform that
committee of the availability of environmental checklists or Environmental Impact
Statements (EISs) on any proposals which that committee is known to be reviewing and
shall provide copies upon request. To the extent the Port establishes any advisory body
similar to a planning  commission (i.e., an advisory body which is required by
Commission resolution or other law to review and make recommendations on a proposal
prior to Commission action), the responsible official shall provide that committee with
any required final threshold determination or final environmental impact statement prior
to that committee's final recommendation to the Commission on whether to approve the
proposal. 
Section 6.5   Applicant Early Review 
If the Port's only action on a proposal is a decision on a permit, lease or license that
requires detailed project plans and specifications, the applicant may request in writing
that the Port conduct environmental review prior to the submission of detailed plans and
specifications. The Port shall initiate review of the proposal at the conceptual stage, if
requested. The Port may require additional environmental review on detailed plans and
specifications at a later date.
Section 6.6   Preferred Alternatives 
The Commission, its committees, or staff may identify a preferred alternative at any time
in the SEPA process - scoping, draft EIS, or final EIS. The identification of a preferred
alternative shall not be construed as an improper commitment to, or as a final decision
on, a particular proposal or course of action. 
Section 6.7   Industrial Revenue Financing 
In  as  much as the borrowing  of funds, issuance of bonds, and related financing
agreements and approvals are categorically exempt under WAC 197-11-800(14)(d), the
adoption of a bond resolution by a public corporation providing for the issuance of
revenue bonds under Chapter 33.84 RCW and subsequent Commission approval of such
resolution may occur prior to environmental review of a project. Environmental review 
under SEPA, if required, must be completed prior to final project approval by the 
Commission and/or other state or local agencies with jurisdiction. 

7

Section 7    Document Information 
Section 7.1   Supporting Documents 
If the Port prepares or cites background or supporting analyses, studies, or technical
reports, such material shall be considered part of the Port's record of compliance with
SEPA, as long as the preparation and circulation of such material complies with the
requirements in these rules for incorporation by reference and the use of supporting
documents. Specific methods for the identification and calculation of Greenhouse Gas
Emissions are identified in Appendix A. 
PART THREE
CATEGORICAL EXEMPTIONS AND THRESHOLD DETERMINATIONS 
Section 8     Adoption by Reference 
This part contains the rules for: (a) administering categorical exemptions for proposals
that would not have "probable significant adverse impacts"; (b) deciding whether a
proposal has a "probable significant, adverse environmental impact" requiring an
environmental impact statement (EIS) to be prepared (threshold determination); and (c)
providing a way to review and mitigate nonexempt proposals through the threshold
determination process. The state SEPA rules in WAC 197-11-300 through 390 are hereby
adopted by reference. They include: 
1.     Not requiring review for proposals that are categorically exempt 
(WAC 197-11-305 and Part 9); 
2.     The requirement to make a threshold determination for any "action" 
that is not categorically exempt (WAC 137-11-310); 
3.     Use of an environmental checklist to assist in making threshold 
determinations for project and non-project proposals (WAC 197-11-315); 
4.     The process and criteria for making a threshold determination 
(WAC 197-11-330); 
5.     How to address a proposal that lacks sufficient information to make a 
threshold determination (WAC 197-11-335); 
6.     Issuing a "determination of non-significance" (DNS) (WAC 197-11-340); 
7.     Including mitigation measures in a DNS (WAC 197-11-350); 
8.     Determining that an EIS is required and issuing a determination of 
significance (DS)/scoping notice (WAC 197-11-360); and 
9.     The effect of a threshold determination (WAC 197-11-390). 
8

Section 9    Categorical Exemptions 
In deciding whether a proposed action is categorically exempt, the SEPA rules identify
certain circumstances when potentially exempt actions would not be exempt (WAC 197-
11-305). In determining whether a proposal is exempt, the Port shall make certain the
proposal is properly defined (WAC 197-11-060). 
Section 9.1   City/County Thresholds 
For minor new construction, the SEPA procedures of the city or county where the
proposal is located should be reviewed to determine the exempt levels that apply to the
proposal (see WAC 191-11-800(1)). Local SEPA procedures should also be reviewed to
determine if the proposal is located in an area that has been designated as a "critical area" 
under WAC 197-11-908 as this may impact whether the proposal is exempt. 
Section 9.2   Proposals with Exempt and Nonexempt Parts 
If a proposal includes exempt and nonexempt actions, the proposal is not exempt and
requires environmental review; however,  the exempt aspects of the proposal may
nonetheless proceed, before or during the environmental review of the proposal, if the
requirements of  WAC 197-11-070 are  met (WAC 197-11-305(1)(b)). A common
example would be the acquisition of a property right option or approval of bond
financing, which would not have an adverse environmental impact or limit the choice of
reasonable alternatives (it might even preserve or increase the availability of alternatives). 
Section 9.3   Categorically Exempt Projects 
Categorically exempt projects shall be documented in a memorandum that includes an
analysis of how the project meets the requirements of WAC 197-11-070.  The
memorandum will be archived in the Port's official SEPA record. 
Section 10   Mitigated DNS 
Mitigation measures may be included in, or added to, a proposal prior to making the
threshold determination so that environmental impacts are reduced or eliminated (WAC
197-11-350). Changes or clarifications to a proposal do not require a new environmental
checklist if the clarifications or changes are stated in writing in documents that are
attachments to, or incorporate by reference, the documents previously submitted. (WAC
197-11-350(4)). A DNS containing mitigation measures may simply he labeled a "DNS"
(as in the form in WAC 197-11-970), and is not required to be formally titled or referred
to as a "Mitigated DNS." 
Mitigation measures that are included in a decision must be documented (see Section 19
below). Although public notice is not required by state law when the Port clarifies or
changes features of its own proposals in a mitigated DNS (WAC 197-11-350(5)), public
and agency notice and a 14-day waiting period are required for mitigated DNSs on
proposals by applicants  (WAC 197-11-340(2)(a)(iv) and Section 15 below). If the
Commission changes the proposal or mitigation measures, the description of the proposal

9

or mitigation measures stated in the decision document (Section 19) shall supersede those
in the mitigated DNS. 

PART FOUR 
ENVIRONMENTAL IMPACT STATEMENT (EIS) 
Section 11   Purpose/Adoption by Reference 
This part contains the rules for preparing environmental impact statements. The state
rules in WAC 197-1l-400 to 460 are hereby adopted by reference. They include: 
1.     The purpose of an EIS (WAC 197-11-400); 
2.     The requirements that apply to the preparation of EISs 
(WAC 177-11-402); 
3.     Three types of EISs: draft, final, and supplemental 
(WAC 197-1 1-405); 
4.     When EISs must be prepared (WAC 197-11-406); 
5.     How to decide the scope of an EIS (WAC 197-1 1-408); 
6.     Optional expanded scoping (WAC 197-11-410); 
7.     Who can prepare EISs (WAC 197-11-420); 
8.     Style and size of EISs, including page limits (WAC 197-11-425); 
9.     Format of EISs, including flexibility for different types of 
proposals (WAC 197-11-430); 
10.    EIS cover letter and memo (WAC 197-11-435); 
11.    Required contents of a EIS (WAC 197-11-440); 
12.    The content of EISs on nonproject proposals, (WAC 197-11-442 ); 
13.   Rules on the content of EISs on proposed projects when there has 
already been a nonproject EIS (WAC 197-11-443); 
14.   The various elements of the environment, consisting of the 
natural and built environment (WAC 197-11-444); 
15.   The relationship of EISs to other considerations such as economic, 
social, or technical factors (WAC 197-11-448 ); 
10

16.   The use of a quantified cost-benefit analyses in a EIS, 
(WAC 197-11-450); 
17.   The procedures for issuing a draft EIS (WAC 197-11-455); and 
18.   The procedures for issuing a final EIS (WAC 197-11-460). 
Section 11.1  Scoping 
The responsible official shall decide the scoping method and deadline for a given
proposal, consistent with WAC 197-11-408. Special attention should be given to writing
scoping notices in plain English and avoiding technical jargon. Scoping techniques can
vary by proposal. Any scoping beyond the minimum in WAC 197-11-408 (including
formal or informal meetings and the use of forms, notices, or documents other than the
form in WAC 197-11-980) shall be considered expanded scoping and is not required for
adequate scoping under state law. If a consultant is preparing an EIS, the consultant's
contact should make provision for possible changes in the scope of the EIS based upon
the scoping process. 
Section 11.2  Additional Scoping 
The expanded scoping provisions in WAC 197-11-410 may be used without formally
designating the process as "expanded scoping." In keeping with the intent of the state
rules, the responsible official is encouraged to be innovative and shall have very broad
discretion in developing creative scoping methods. A scoping process may also be used
before a threshold determination (or at any other time in the SEPA process) to assist 
in identifying impacts and alternatives, including mitigation measures. If so, the form of 
the scoping notice shall be revised accordingly, so that agencies and members of the
public understand the purpose and process being used. 
Section 11.3  EIS Preparer 
An EIS may be prepared by Port staff, consultants on contract to the Port, or other private
entities under the direction of the responsible official. If an applicant's consultant is 
preparing the EIS, the applicant shall consult with the responsible official prior to final
selection of consultants. The responsible official shall have the discretion to design the
EIS process and carry out the responsibilities set forth in WAC 197-11-420. 
Section 11.4  Non-Environmental Information 
The responsible official may include non-environmental information on any subject
relevant to a decision in an EIS. The information may be in the EIS or in other 
documents and shall not be used in determining whether an EIS meets the requirements
of SEPA (WAC 147-11-440(8)).
Section 11.5  Mitigation Commitments 
The Port is not required to commit to mitigation measures in an EIS itself.  Mitigation
measures that are identified and expressly committed to by the final decision-maker at the

11

Port  (See Section 19 below)  shall  be incorporated into design plans and, where
applicable, construction contracts. 
Section 11.6  Climate Change and Determination of Adverse Impacts 
There is no uniform standard for determining "significance" with respect to greenhouse
gas emissions from a project and to the possible effects of climate change on a proposal.
Any decision by the Port of whether there is adverse environmental impact from a
proposal will be made on a case-by-case basis.

PART FIVE 
COMMENTING 
Section 12   Purpose/Adoption by Reference 
This part explains how to comment and respond on all environmental documents under
SEPA, including rules for public notice and hearings. The Port may receive comments on
its own proposals and may comment on other agencies' proposals or environmental
documents. The state rules in WAC 197-11-500 to 570 are hereby adopted by reference.
They include: 
1.     The purpose of the commenting provisions and list of notice and time 
requirements (WAC 197-11-500 and 502); 
2.     Making environmental documents available (WAC 197-11-504); 
3.     Filing environmental documents with the State SEPA register (WAC 197- 
11-508); 
4.     Providing public notice (WAC 197-11-510); 
5.     Public hearings and meetings procedures (WAC 197-11-535); 
6.     The effect on agencies and the public of not commenting on 
environmental documents (WAC 197-11-545); 
7.     Specific commenting requirements (WAC 197-11-550); 
8.     Response to comments in FEISs (WAC 197-11-560); and 
9.     Prohibiting consulted agencies from charging lead agencies for 
assistance under SEPA (WAC 197-11-570). 
Section 13   Port SEPA Comments to Other Agencies 
The Port's Environmental Programs shall be responsible for coordinating and preparing
Port comments to other agencies on the environmental documents of other agencies.
Environmental Programs shall also be responsible for coordinating consultationrequests 
12


under SEPA from other agencies to the Port. The responsible official or designee shall
sign written comments from the Port and may establish deadlines for responses from
offices within the Port in order to meet commenting deadlines established by law or by
other agencies in their requests. 
Section 14   Costs for Port Environmental Documents 
Normally, after the initial  printing, the Port will charge for the copying of its
environmental documents.  Copying charges will be consistent with the requirements of
Chapter 42.56 RCW and WAC 44-14-07001. The Port will not charge other agencies to
which the Port is required by law to send the documents. The Port may make documents
available without charge. The Port may, if requested, reduce or waive charges for a
document provided to a public interest organization. The responsible official may
establish internal policies or procedures or make determinations on an individual basis.
Section 15   Public Notice 
In addition to the circulation requirements to other agencies and affected tribes, the Port
will give public notice in the following manner: 
Section 15.1  Required Notices 
For threshold determinations that require notice under Chapter 197-11 WAC, scoping
notices, EISs, and public hearings on a draft EIS the Port shall: 
1.     Publish notice in a newspaper of general circulation in the county, city, 
general area where the proposal is located (if there is more than one 
newspaper, the responsible official may select one newspaper for 
publication); 
2.     Furnish notice to anyone who has specifically requested in writing to be 
notified about the particular proposal; 
3.     File the documents required by WAC 197-11-508 with the state 
Department of Ecology for publication of notice in the SEPA 
Register; 
4.     (For EIS and Public Hearings on a DEIS only) issue a press 
release announcing the EIS or the Public Hearing; 
5.     (For EISs and Public Hearings on a DEIS only) create or maintain a 
mailing list based on responses during the scoping process and send notice
to those on the list. This list may be combined with any list kept by the 
Port pursuant to Section 15.1.2 above. 
6.     Publish notice on the Port's website: www.portseattle.org. 
Section 15.2  Additional Optional Notice 

13

For proposals of sufficient size and complexity or that have community sensitivity, in
addition to notification required under Chapter 197-11 WAC, the Port may: 
1.     Publish notice in Port newsletters, if any; 
2.     Notify the news media orally or by press release, including 
neighborhood newspapers or trade journals; 
3.     Post the property, for site specific proposals; 
4.     Increase the length of public comment; 
5.     Request that a notice be posted on the main bulletin board, if 
any, at the city or county council or planning department where 
the proposal is located; 
6.     Create or maintain a mailing list for a particular proposal or type of 
proposal, which may include the identification of citizen and public 
interest organizations, and send notice to those on the mailing list; or 
7.     Use other reasonable methods appropriate to a particular proposal. 
Section 15.3  Notices of Adoption and Addenda
Notices of adoption and addenda shall be circulated as required by WAC 197-11-625 and
630, respectively. The date of issue is the date the document has been made publicly
available and sent to the required recipients. A decision document (Section 19) shall be
provided to anyone requesting it. 

PART SIX 
USING EXISTING ENVIRONMENTAL DOCUMENTS 
Section 16   Purpose/Adoption by Reference 
This part contains rules for the Port's use of existing environmental documents for its
SEPA compliance. The "existing" documents might be prepared by the Port or by local,
state, or federal agencies under SEPA or NEPA (National Environmental Policy Act, 43
USC 4321 et seq.). The state rules in WAC 197-11-600 through 640 are hereby adopted
by reference. These rules include: 
1.     When to use existing environmental documents (WAC 197-11-600); 
2.     Use of NEPA documents, including environmental assessments (WAC 
197-11-610); 
3.     Procedures for Supplemental Environmental Impact Statements (SEISs) 
(WAC 197-11-620); 
14

4.     Procedures for addenda (WAC 157-11-625); 
5.     Procedures for adoption (WAC 197-11-630); 
6.     Procedures for incorporation by reference (WAC 197-11-635); and 
7.     How to combine SEPA and other documents (WAC 197-11-640). 

Section 17 Adoption Hearing and Addenda 
Section 17.1  Federal Adoption Hearing 
If the Port has issued a notice to adopt a federal environmental document as a substitute
for preparing a SEPA EIS, and a federal agency subsequently holds a hearing on the
environmental document, the federal hearing may be combined with and, if so, shall
suffice for any public hearing required under (WAC 197-11-610). 
Section 17.2   Addenda 
If subsequent environmental design detail or other environmental analysis is necessary or 
desirable and a SEIS is not required (it does not meet the two criteria in WAC 197-11-
600(3)(b)), then an addendum may be used to conduct or document the analysis. An
addendum may be used to add to any kind of environmental document, and may be used
at any time in the SEPA process.

To the extent the Port conditions or denies proposals under SEPA, the document required
by the preceding section shall cite the agency SEPA policy (from Section 20 below or
from other policies, plans, rules, or resolutions formally designated by the Port) that is the
basis for conditioning or denying the proposal. 
Section 20   Port SEPA Policies 
The Port adopts by reference the state environmental policy as set forth in SEPA, RCW
43.21C.020. Specifically, in order to carry out the policy set forth in SEPA, it is the Port's
continuing responsibility to use all practicable means and measures, consistent with other 
essential considerations of state policy, to improve and coordinate plans, functions,
programs, and resources to the end that the Port, the state, and its citizens may: 
1.     Fulfill the responsibilities of each generation as trustee of the environment
for succeeding generations; 
2.     Assure for all people of Washington safe, healthful, productive, and 
aesthetically and culturally pleasing surroundings;

degradation, risk to health or safety, including from hazardous waste or 
other toxic substances, or other undesirable or unintended consequences; 
4.     Preserve important historic, cultural, and natural aspects of our national 
heritage; 
5.     Maintain, wherever possible, an environment which supports diversity 
and variety of individual choice; 
6.     Achieve a balance between population and resource use which will permit 
high standards of living and a wide sharing of life's amenities; 
7.     Enhance the quality of renewable resources and approach the maximum 
attainable recycling of depletable resources; 
8.     Manage public waterways and adjacent lands, fisheries, and other natural 
resources wisely; and 
9.     Mitigate probable adverse environmental impacts resulting from 
proposals, particularly significant impacts, to the extent of the Port's 
authority and guided by the policies stated above and in SEPA and the 
Port's other statutory responsibilities. 
16

10.    Consider greenhouse gas emissions and the effect of changes in climate on

Appendix A  SEPA AND CLIMATE CHANGE 
PART ONE 
SEPA AND CLIMATE CHANGE 
Section 1    SEPA and Climate Change
SEPA requires lead agencies to consider the environmental consequences of proposals
that are not exempt from the SEPA process. Climate is one element of environment that
SEPA requires agencies to evaluate before making a decision on a proposal (WAC 197-
11- 444)(1)(b)(iii). As a lead agency and project proponent, the Port will consider
greenhouse gas emissions and the effect of changes in climate on proposed actions as a
mandatory component of our environmental review. 
SEPA provides a framework for considering environmental impacts of proposed actions.
With respect to climate change, the SEPA analysis of the environmental impacts of a
proposal may include the following steps, which are part of the standard SEPA review
process: 
1.  Reasonable identification, calculation, or other evaluation of greenhouse gas
emissions associated with the project, 
2.  Identification of reasonable mitigation that avoids, reduces, or compensates for
the adverse effects of the emissions, 
3.  Assessment of the potential effects or impacts that climate change may have on
the project itself, 
4. Assessment of the "significance" of the unmitigated emissions associated with the
project, 
5. Assessment of the "significance" of climate changes on the project, 
6.  If required, the preparation of an Environmental Impact Statement (EIS) that:
(a)analyzes the environmental impacts of a project's greenhouse gas emissions
and the effect of climate change on a project, (b) identifies alternatives, and (c)
possible mitigation options.
PART TWO 
IDENTIFICATION AND CALCULATION OF GREENHOUSE GAS EMISSIONS 

Section 2    Calculation of GHG Emissions 
The Port project proponent will identify and calculate both direct and indirect greenhouse
gas emissions within reasonable spatial and temporal boundaries of a proposal as part of
SEPA environmental review. Project proponents should evaluate their proposal for all
known or expected sources of greenhouse gases that they can reasonably assess or
calculate over the life of the project. The rigor of the greenhouse gas calculation or
assessment will depend on the scope, scale and context of a particular proposal. The
23

proponent should distinguish between those emissions that are under the direct control of
the project proponent from those that are owned and/or controlled by third parties. For
many projects, a reasonable qualitative estimate of emissions may be sufficient. For
others, particularly those projects that may be covered by the State of Washington's
mandatory greenhouse gas reporting requirement or any other reporting requirement
adopted by the United States Environmental Protection Agency, more rigorous
quantification methods might be appropriate.
Section 3    Emissions Quantification Methodologies 
Project proponents should use well-accepted emission quantification methodologies
appropriate and reasonable for the scope and scale of a project when calculating or
otherwise assessing emissions from a project. Attachment 2 to this resolution identifies
well-accepted quantification methodologies currently used for many of the most common
emission sources and may be utilized by project proponents to assist in calculating and
evaluating emissions. The Port may develop and utilize its own methodologies based
upon best available emission factors and project specific information.

Section 4    Emissions Worksheet 
Environmental review normally starts with the completion of an environmental checklist.
The checklist provides information to the lead agency about the proposal and its probable
environmental impacts. The State of Washington and other local government agencies
have developed quantitative and qualitative worksheets that may serve as templates for
calculating the relevant sources of GHG emissions from a proposal. A greenhouse gas
emissions worksheet may provide supplemental information for the environmental
checklist.
PART THREE 
MITIGATION MEASURES 
Section 5    Mitigation Measures 
Mitigation is the avoidance, minimization, rectification, compensation, reduction, or
elimination of adverse impacts to built and natural elements of the environment. As a
project proponent, the Port may incorporate mitigation measures that reduce a project's
greenhouse gas emissions below a level of significance or take voluntary actions that
reduce the Port's greenhouse gas emission baseline. Mitigation measures that reduce or
avoid greenhouse gas emissions should be identified in appropriate environmental
documents. Project proponents should work with POS environmental staff early on in the
proposal to identify possible GHG mitigation measures and strategies for the project.
PART FOUR 
THRESHOLD DETERMINATION 

Section 6    Threshold Determination 

24

The SEPA "threshold determination" is the formal decision as to whether the proposal is
likely to cause a significant adverse environmental impact for which mitigation cannot be
easily identified. With respect to greenhouse gas emissions from a project and to the
possible effects of climate change on a proposal, there is no uniform standard for
determining "significance." Any decision by the Port of whether there is adverse
environmental impact from a proposal will be made on a case-by-case basis.
In making the threshold determination, the Port as a lead agency may consider: 
1.  Whether the proposal will significantly contribute, either directly, indirectly or
cumulatively to greenhouse gas concentrations in the atmosphere; 
2.  The extent to which greenhouse gas emissions of the project have been mitigated
as part of project design, or through other identified actions; 
3.  The economic and technical feasibility of mitigation options available;
4.  The aggregate Port greenhouse gas emission inventory and the relation of the
project's emissions to the overall balance and trend of the inventory; 
5.  The effects of climate change on the project, including the vulnerability of the
project to the specific impacts of climate change within a reasonable timeframe; 
6.  Whether the proposal will conflict with applicable laws and regulations adopted
for the purpose of reducing greenhouse gas emissions, 
7.  Guidance and policies adopted by other local governments, and state and federal
agencies, including, but not limited to, the Washington State Department of
Ecology, and the White House Counsel on Environmental Quality related to the
consideration of climate change and greenhouse gas emission under SEPA and
the National Environmental Policy Act (NEPA), 42 U.S.C.  4321 et seq.
If the emissions from the project, or the effects of climate change on the project, will not
be mitigated below the level deemed to be significant, the preparation of an environment
impact statement (EIS) will be required. Additional mitigation measures may be required
to the extent attributable to the identified adverse impacts of the proposal.
PART FIVE 
EFFECTS OF CLIMATE CHANGE 
Section 7    Consideration of Effects of Climate Change on Proposals/Projects
Climate change can affect the environment of a proposed action in a variety of ways. For
instance, climate change can affect the integrity of a development or structure by
exposing it to a greater risk of floods, storm surges, or higher temperatures. Climate
change can increase the vulnerability of a resource, ecosystem, or human community,
causing a proposed action to result in consequences that are more damaging than prior
experience with environmental impacts analysis might indicate. Climate change effects
should be considered in the analysis of 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.
