In an August 20 notice, the Washington Department of Revenue announced it would extend the tax exemption for “hog fuel” wood waste, debris from the logging industry grinded into small chips used in boilers and to produce biofuels. Stakeholders have estimated that the exemption and an associated tax credit have saved the industry between $1.8 and $2 million. The exemption had expired June 30, but the announcement extends the exemption until June 30, 2024.
