The SEPA Handbook is intended to be used in conjunction with the State Environmental Policy Act (Chapter 43.21C RCW) and the SEPA Rules (Chapter 197-11 WAC). Should a conflict be found at any time between the guidance in this handbook and either the SEPA Rules or the RCW, it should be understood that this handbook is intended as guidance only, and does not have the legal standing of the RCW or the Rule.
