The purpose of this chapter shall be to provide guidance regarding the determination of facilities as health care facilities as defined for purposes of chapter 70.37 RCW, and the resulting eligibility for authority financial assistance. If a facility owned or operated by a participant (as defined in RCW 70.37.020(4)) is determined to be a health care facility, it shall be eligible for financing provided by the authority. If a facility is determined not to be a health care facility, then the authority shall not provide financing for such facility. If a facility is used for both health care and nonhealth care uses, then only those portions of the facility which are determined to be health care facilities shall be eligible for financing provided by the authority.
