Delaying or weakening emission regulations will impact thousands of communities nationwide
The EPA is “taking steps to provide relief to wood heater manufacturers and retailers” according to a statement released by the EPA. The EPA expects to issue a proposed rule this spring that could potentially weaken parts of the regulations enacted under the Obama administration.
January 2019 update: The EPA has proposed giving a 2-year sell through for wood boilers and furnaces, allowing manufacturers to make and sell Step 1 units right up until May 2020. Those units could then be sold through May 2022 by manufacturers directly or by retailers. Attorney Generals from seven states filed comments saying the EPA did not have the legal authority to provide such sell-throughs, portending a legal fight.
March 2020 update: The EPA issued its final rule and decided not to provide any sell-through periods for any class of wood heater.
The April 2018 move to provide relief is supported by companies such as Central Boiler, the largest outdoor wood boiler manufacturer in North America, who has been aggressively lobbying to delay and weaken the standards that were to come into effect in 2020. But to some smaller companies who have already invested in the R&D to meet the stricter 2020 standards, the EPA announcement undermines the significant investment they’ve made in designing cleaner and more efficient wood heaters.
Thousands of cities, towns and communities are impacted by excessive wintertime levels of wood smoke, posing health risks and undermining support for an iconic renewable energy technology.
It is widely expected that part of the relief that EPA will be providing to industry is a three-year delay in the emission standards that were set to take effect in June 2020. Republicans in the House of Representatives had already passed legislation for a three-year delay, but the Senate has not. A court filingby the EPA said that it “intends to take final action on this first proposed rule by this fall,” and that would allow manufacturers to slow down their R&D and certification testing.
But the EPA can pick and choose which parts of the Obama era wood heater regulations that it wants to rewrite and they say they will issue a series of federal register notices asking stakeholders for comment and input on substantive issues. Experts believe that a statement released by the EPA indicate that emission test methods are being considered.
Environmental groups, industry and the EPA have been wanting to move away from testing and certifying wood stoves with crib wood – 2x4s and 4x4s – which has been the standard testing fuel since the first set of wood stove regulations in 1988. All parties want to switch to using cordwood, the fuel used by homeowners, recognizing that stoves have been fine tuned to run better on crib wood, rather than cordwood. This has resulted in stoves that may run at 4 grams an hour of smoke in the lab, but may be 10 grams an hour or more in the hands of homeowners. In a statement this week, the EPA said it is concerned that its regulation“may not be achieving the environmental benefits it was supposed to provide.”
The EPA appears likely to accelerate the transition to testing with cordwood but industry seems to favor an ASTM cordwood test method while some states and others are developing a new method that reflects how stoves are used by homeowners. This method, call the Integrated Duty Cycle (IDC) method is still in draft form and is a drastic departure from the traditional way that stoves have been tested since the 1988.
The EPA could also decide to weaken emission limits for wood boilers, which would primarily benefit the outdoor wood boiler industry led by Central Boiler.
Since the 2015 regulations went into effect, scores of wood and pellet stoves and boilers have been tested to meet the 2020 standards and most prices have not gone up significantly. The 2015 regulations began a process of requiring that manufacturers test and report their efficiencies, and delaying the 2020 deadline would set back efficiency disclosures, harming the ability of consumers to choose more efficient appliances.
States are allowed to set stricter standards but not looser ones, and if the EPA were to weaken the federal rule too much, some states could either stick to the original standards set by the Obama administration in 2015 or develop new ones. States like New York, Oregon, Vermont and Washington are already battling long-term wood smoke problems and have started to chart their own course for wood heater regulations. If several states adopted a different cordwood test method or stricter emission standards, they could have a “California effect” of moving the entire market.
“We are very concerned that the Trump Administration may weaken consumer and environmental protections for wood stoves,” said John Ackerly, President of the Alliance for Green Heat, an independent non-profit that promotes cleaner and more efficient residential wood heating. “Wood and pellet stoves are vital to help families affordably reduce fossil heating fuels, but we can’t move this technology forward unless they can burn cleaner in people’s homes,” he said.
March 11, 2020 update: The EPA finalized amendments to the 2015 NSPS and did not provide a retailer sell-through or any extensions for central heaters or room heaters. They did remove pellet fuel minimum requirements but retained the list of prohibited fuels in the 2015 NSPS.
