The Washington State Department of Ecology (DOE) was created in February 1970 after the Washington State Senate voted in favor of Senate Bill 1 and Governor Daniel Evans signed the bill into law. The bill authorized the consolidation of four existing state agencies to create the Department of Ecology, the first unified environmental protection agency in the nation, ahead of even the U.S. Environmental Protection Agency.
