Biomass Industry Wants New Boiler Rules from EPA

Proposed regs are already having a 'chilling effect' on new projects, industry says

Aug 26, 2010

The biomass industry is demanding that U.S. EPA revamp newly proposed standards that would impose strict emissions limits on the boilers at its wood-burning plants, saying the billions in equipment upgrades would "endanger" the "entire renewable energy industry."

The Biomass Power Association (BPA), a trade group with members in 20 states, said on Wednesday it is appealing to EPA for special protections under a series of maximum achievable control technology (MACT) standards for industrial boilers.

Two rules – the boiler MACT and the area source MACT – are at the heart of BPA's concerns.

The association said they would impose unnecessary regulatory burden on a $1 billion industry that it says causes no environmental harm or public health threats.

"The problem is that EPA is trying to create this one-size-fits-all-approach — not distinguishing among fuels, and not distinguishing among boilers," Bob Cleaves, BPA president and CEO, told reporters. "A one size fits all will not move the [biomass] industry forward."

Cleaves said the rules would impact all of the nation's current 100 biomass facilities. For potential new projects, he said, just the prospect of having to install state-of-the-art pollution controls is having a "chilling effect."

"Because of that we are asking EPA [to move] on an expedited basis," Cleaves said.

BPA submitted comments to the EPA on August 23, just as the 45-day comment period came to a close. Final regulations are expected at the end of the year.

Enesta Jones, an EPA spokesperson, told SolveClimate News that the agency intends to take BPA's complaints into account.

"We will take comments from the association into consideration — along with all public comments — as we prepare our final regulations," she said in email.

The biomass industry burns organic waste material — mainly wood — to make electric power, generating pollution, including particulate matter. Advocates say it is a proven carbon-neutral alternative to fossil fuels. But for opponents, an increase in biomass facilities would cause more air pollution and could lead to the destruction of vital carbon-absorbing forests.

Today's controversy over the EPA rules highlights the uphill battle the industry faces in gaining recognition as a clean-burning fuel source.

In June, a study in Massachusetts set off a firestorm by claiming that burning woody biomass would be more polluting than coal for at least the next several decades. The study prompted a change in the way that state provides renewable energy incentives to biomass projects.

Boiler Standards Impossible to Meet

EPA's MACT standards set limits on hazardous air emissions across 28 large industry sectors. Under the Clean Air Act, the agency must review them every eight years.

The boiler rules have been several years in the making.

Proposed on June 4, the standards would reclassify the boiler units at biomass plants as "incinerators." The designation would subject them to stricter emissions limits for several toxic pollutants, including mercury, hydrogen chloride, manganese, carbon monoxide and dioxin.

The limits are impossible to meet, according to Cleaves. They would require installation of a non-existent "huber boiler” unit, he expained, with an emissions-reduction capacity "greater than what technology can possibly deliver in today's world."

"No such boiler can achieve all of the emissions standards that EPA is proposing in their rules," he said.
