House approves voluntary program to reduce wood-smoke emissions during inversions

The Utah House on March 6 passed House Bill 154, a measure aimed at reducing wood-smoke particulate pollution during winter inversion periods by funding education and offering voluntary conversions for sole-source wood-heated homes.

Representative Arendt, a sponsor, said research from the University of Utah shows burning one wood stove for one hour during an inversion produces high PM2.5 emissions and argued conversion programs are a cost'effective way to cut pollution. "This bill is designed to address the wood burning issue," Arendt said, describing the proposal as a two-part approach: public education and assistance to convert homes that rely solely on wood heat.

Co-sponsors and supporters emphasized health and economic benefits. Representative Nielsen said converting a wood-burning home to a cleaner heating source can be a relatively low-cost way to eliminate a ton of pollution compared with industrial controls, estimating a cost of about $7,500 per ton avoided in some cases. Representative Red cited research estimating wood smoke contributes roughly 5'7% of PM2.5 during inversions, calling it "low-hanging fruit."

Rural members raised concerns about households without access to natural gas and the expense of conversions. Representative Menlove noted that bringing natural gas to some rural homes can cost tens of thousands of dollars. Sponsors responded that the program targets only those on a "sole source" list and is optional; the Division of Air Quality will implement program details through rulemaking and outreach.

After extended discussion on equity and statewide impacts, the House passed HB 154 by a roll-call vote, 43 yes to 28 no. The bill will be transmitted to the Senate for further consideration.
