What we could not check in Washington
Some Washington sources could not be reached during our review. We list what we tried and what happened, so you can judge the gap yourself rather than read an empty table as an answer.
-
Regional clean air agency wood stove programs —
WA administers wood stove changeouts REGIONALLY and several of these agencies likely have active rebates, but correct program URLs were not confirmed (404s after redirect, unrelated content returned, or URLs never located). This is the second-highest-priority gap after MA — WA is a high-probability state and these five agencies cover most of its population.
