Industry and Air Quality Agencies Spar at EPA’s Public Hearing on New Wood Stove Regulations

Most of the controversy at the EPA’s public hearing on their new residential wood heater regulations was not about outdoor wood boilers or other unregulated heaters but about the traditional wood stove.

Wood from the EPA listen to testimony
at the Boston public hearing.

The largest bloc of speakers was from industry that appeared to have a well-coordinated, consistent message that these rules are ill-conceived and counter-productive.  Most of the industry speakers made the point that the rules would likely raise the cost of stoves considerably, thereby slowing the switch from old, more polluting stoves to new, cleaner ones.  They said that the solution to wood smoke should focus on changing out older stoves, not trying to squeeze another gram per hour or two out of newer ones.

More than a dozen air quality officials and advocates spoke just as passionately about the need for cleaner stoves, expressing general support for the proposed regulations and arguing for a short timetable for them to take effect.  State officials from New Hampshire, Vermont, Massachusetts, Connecticut, Minnesota and Washington argued for the regulations while one state, Maine, sided much more with industry.  Patricia Aho, Commissioner from the Maine Department of Environmental Protection expressed many reservations about the proposed rule, including strong reservations about a move toward more catalytic stoves.  Several state officials called for Phase 1 standards, which take effect right away, to be stricter.

An assistant for Senator Patrick Leahy from Vermont said the Senator was generally supportive and would be providing formal written comments.  He, like many of the speakers, talked about the importance of wood stoves for middle and lower-income consumers.  A legislator from Missouri on the opposite side of the political spectrum said it is clear that the “EPA is trying to outlaw wood stoves” and that the EPA should not allow “environmental groups to be involved in the rulemaking.”

One notable difference between the EPA and most state officials is that the latter all talked about the importance of wood and pellets as a local, affordable and renewable energy source, themes that are largely absent in the EPA proposal or website.

One consistent talking point echoed by many industry presenters was that catalytic stoves performed well only in the laboratory and that consumers did not operate them well in their homes, leading to excess pollution.  Many in industry called on the EPA to allow non-catalytic stoves to meet a more lenient emission standard while holding cat stoves to a more stringent one.  Tom Morrissey, owner of Woodstock Soapstone vigorously defended catalytic stoves and called into question a report funded by US and Canadian non-cat producers.

While most of industry speakers supported change-outs over tighter emission standards for new stoves, one manufacturer who makes the exempt, uncertified stoves seemed to be advocating for the continued ability to sell these stoves.  The EPA estimates that about 20,000 new exempt, uncertified stoves are sold and installed each year. 

Many of the manufacturers argued for the need for sell-through periods and more lead-time to comply with the new standards.  Other stakeholders called for an end of the sale of unqualified outdoor wood boilers as soon as possible, with no sell-through period. 

An importer of European boilers urged the EPA to also accept the Brookhaven test method for boilers with thermal storage and set an achievable emission target for that method which includes start-up emissions.  A retailer of Central Boiler outdoor boilers from New Hampshire talked about his lower-income consumers who could not afford a qualified unit, and urged the EPA to allow him to a reasonable sell-through period for his qualified units.

A manufacturer of fireplaces called on the EPA to regulate fireplaces, instead of exempting them again, as the EPA proposes.  The American Lung Association strongly supported this, also urging that fireplaces be regulated.  Several representatives of masonry stove builders urged the EPA to further work with them to ensure that their units could be certified.

The CEO of US Stoves noted that the SBA and OMB had serious problems with the EPA’s proposed rules and stressed how many of their customers were from low-income homes that are very sensitive to even small price increases.  US Stoves and others currently sell quite a few EPA certified models in the $600 - $900 range, comparable to the price of stoves in the 1970s when adjusted for inflation.


Several organizations, including the Alliance for Green Heat, spoke of the benefits of consumers having access to third-party verified efficiency numbers using a consistent efficiency measurement and having that number prominently displayed on a hang-tag on the showroom floor.  The EPA proposed to eliminate the hangtag with no explanation as to why.

Pro-wood heating group says EPA regulations reasonable and will help industry grow


The Alliance for Green Heat welcomed the release of proposed EPA regulations on residential wood and pellet heating equipment, saying that new, stricter emission standards “will help America embrace wood and pellet heating as a vital renewable energy that can help drastically reduce fossil fuel consumption.”

More than 10 million American homes heat with wood and pellets, ten times more than solar and geothermal combined, according to data from EIA and the US census. “We can harness the huge demand for this type of renewable energy if the stoves and boilers are clean enough,” said John Ackerly, President of the Alliance for Green Heat. “We believe the emissions numbers released by the EPA today are reasonable and achievable and will help the wood stove industry grow and thrive in coming decades,” Ackerly continued.

The proposed rule has few surprises in terms of emission numbers. Virtually all the key numbers were included in draft proposed rules shared with industry, states and non-profits during 2013. But the proposed rule does reflect the much stricter numbers the EPA developed after states and air quality agencies intervened in 2012. Previously, the EPA was considering 2.5 grams per hour to be the strictest level for wood and pellet stoves. But last year, the EPA floated a 1.3 grams per hour for all pellet and wood stoves and that is the number that was released today.

The EPA is proposing that wood and pellet stoves initially meet a 4.5 grams per hour standard, and then meet a much stricter standard of 1.3 grams per hour 5 years after promulgation. Alternatively, the EPA proposes a 3-step process of going to 2.5 grams per hour after 3 years and then 1.3 grams an hour after 8 years.

Similarly, the EPA is proposing two options for furnaces and boilers. The first would establish strict emission limits after 5 years, and the second would have an intermediate step after 3 years, and then the stricter standard after 8 years. Initially, warm air furnaces would only be held to 0.93 lb/MMBTU, whereas hydronic heaters would be held to 0.32. Ultimately, both would need to reach 0.06 lb/MMBTU either 5 or 8 years after promulgation. It is widely anticipated that industry will advocate for the 3-step process and that EPA would be open to this as well.

The EPA’s press release said that “when these standards are fully implemented ... [c]onsumers will also see a monetary benefit from efficiency improvements in the new woodstoves, which use less wood to heat homes.” However, the EPA decided not to include any efficiency standard, leaving open the possibility that some very inefficient units may remain on the market. Wood and pellet heating appliances are the only HVAC equipment without minimum efficiency standards.

Both efficiency and CO would have to be recorded and reported under the new proposed rules. To avoid logjams in testing to the new standards, the EPA is proposing “to allow ISO-accredited laboratories and ISO-accredited certifying bodies to increase the availability of laboratories and certifiers.” 

The EPA is scheduling a public hearing on these regulations in Boston on February 26. Interested parties should register by February 19 at http://www2.epa.gov/residential-wood-heaters if they want to make public comments. Each person will be limited to 5 minutes. The public has 90 days to comment on the regulations after they are posted in the Federal Register, which is expected to happen in the next week or two. 

The proposed rule does offer an unusual glimpse into disagreements between the EPA, the Small Business Agency (SBA) and the Office of Budget and Management (OMB).  In the Panel Report, the “SBA and OMB recommended that the EPA not move forward with proposed emission limits for pellet stoves, indoor hydronic heaters, biomass pellet stoves, masonry heaters.” The EPA however rejected this recommendation and provided a sound basis for their proposal to include pellet stoves, all hydronic heaters and masonry heaters.

The SBA and OMB also recommended that the NSPS only cover parts of the country where wood smoke pollution was high. They suggested that states and regions where wood smoke is not high be allowed to issue their own regulations and consider voluntary standards. The EPA chose to highlight and counter these recommendations in its proposed rule, showing that they have considered these options but found they were not justified.

The Alliance for Green Heat is a non-profit consumer advocacy organization that fights for cleaner and more efficient wood and pellet heating to help households affordably switch to a renewable heating fuel.
