Horse Heaven SEPA
SEPA
The State Environmental Policy Act (SEPA) is a Washington State law known as the Revised Code of Washington (RCW) 43.21C. RCW 43.21C was enacted in 1971 which requires state and local agencies to identify and analyze the adverse environmental impacts of a proposal before making a decision on that proposal (RCW 43.21C.030). As part of analyzing the proposal for impacts, EFSEC sends data requests to the applicant requesting additional information or clarification regarding their proposal and/or the site. When a decision is made to prepare an Environmental Impact Statement (EIS) for SEPA review, the EIS process is initiated with a Determination of Significance (DS). EFSEC announces the DS in a Scoping Notice which begins a public comment period. EFSEC is required to consider all comments received during Scoping in determining the Scope of the EIS but is not required to respond to those comments in writing. A Scoping Report or Memo can be prepared and informs the public about the comments received during Scoping and how that information will set the Scope of the EIS. Once the Scope of the EIS is determined, a draft EIS is prepared. The draft EIS is reviewed by EFSEC and subject matter experts. EFESC opens a public comment period and holds a public meeting to receive public comments. EFSEC requests additional information from the applicant through data requests, performs additional studies if needed and updates substantive information received during the public comment period to create the Final EIS (Environmental Impact Statement).

Draft EIS
Draft EIS
NOTE: Some files are large and may take a long time to download.
A Draft Environmental Impact Statement (EIS) provides information about the adverse environmental impacts of a project proposal. It examines a no action alternative which discusses impacts to the same environment but without the project proposal. It also presents reasonable alternatives, if identified, that could feasibly attain or approximate a proposal’s objectives, but at a lower environmental cost or decreased level of environmental degradation (WAC 197-11-440 (5)). SEPA considers both the natural environment (earth, air, water, plants, animals) and the built environment (e.g. land use, environmental health, cultural and historic resources, utilities) (WAC 197-11-660). The EIS focuses on the environmental resources that would have significant adverse environmental impacts. However, the EIS usually includes analysis of nonsignificant impacts because:
1) the determination of significance occurs after the analysis has occurred and all feasible mitigation has been identified;
2) the information reflects the thought process for determining an impact is nonsignificant;
3) nonsignificant impacts of the proposal considered together can increase an impact;
4) nonsignificant impacts of the proposal can contribute to a cumulative impact to a resource from multiple actions over time; and
5) identification of mitigation for nonsignificant impacts also incrementally benefits the environment.
The Draft EIS is reviewed by the public (including the applicant), other agencies, and tribal governments during a minimum 30-day comment period; the resulting input is used to improve the environmental analysis for the document and produce a Final EIS. The Draft EIS represents EFSEC’s best effort to provide complete and accurate information about the environmental impacts of the proposal, alternatives, and recommended mitigation to reduce those impacts. Public review of the Draft EIS provides an opportunity to identify missing, incomplete, or incorrect information to be addressed in support of the completeness and accuracy of the Final EIS.
The Final EIS is the official final document that analyzes the adverse environmental impacts of a proposal and must be used by agency decision makers, along with other relevant considerations or documents in making final decisions on a proposal. The lead agency considers comments on the proposal received during the Draft EIS comment period, responds to them, and includes those responses in the Final EIS. The Final EIS provides a basis upon which the responsible agency and officials can make the balancing judgment (e.g. environmental, welfare, social, economic) mandated by SEPA because it provides information on the environmental costs and impacts (WAC 197-11-448).
The Draft EIS was issued on December 19, 2022 and is open for public review and comment until the close of the Public Comment Period on February 1, 2023.
