What is SEPA?
SEPA is the abbreviation or acronym for the State Environmental Policy Act, Chapter 43.21C RCW. Enacted in 1971, it provides the framework for agencies to consider the environmental consequences of a proposal before taking action. It also gives agencies the ability to condition or deny a proposal due to identified likely significant adverse impacts. The Act is implemented through the SEPA Rules, Chapter 197-11 WAC.
