Wash. Admin. Code § 197-11-640
The SEPA process shall be combined with the existing planning, review, and project approval processes being used by each agency with jurisdiction. When environmental documents are required, they shall accompany a proposal through the existing agency review processes. Any environmental document in compliance with SEPA may be combined with any other agency documents to reduce duplication and paperwork and improve decision making. The page limits in these rules shall be met, or the combined document shall contain, at or near the beginning of the document, a separate summary of environmental considerations, as specified by WAC 197-11-440(4). SEPA page limits need not be met for joint state-federal EISs prepared under both SEPA and NEPA, in which case the NEPA page restrictions ( 40 C.F.R. 1502.7 ) shall apply.
