State Environmental Policy Act notices

The Washington Legislature in 1971 enacted the State Environmental Policy Policy Act, RCW 43.21c, often referred to as SEPA. 

The act helps state and local agencies identify possible environmental impacts that could result from governmental decisions, such as:

  • Issuing permits for private projects, such as office buildings, retail stores or apartment complexes.
  • Constructing public facilities, such as schools and roads.
  • Adopting regulations, policies and plans.

Project or proposal proponents are usually asked to complete an environmental checklist. The checklist asks questions about the project or proposal and its potential effects on air, environmental health, plants, transportation, utilities, water and other items.
