EPA watchdog issues second stinging report on the EPA’s wood heater program

The EPA’s Office of Inspector General found continued lack of enforcement of the EPA wood heater regulations, more than a year after its first major investigative report found similar issues. Unlike that in-depth report, this new report cites very specific details of instances where manufacturers and labs have violated EPA regulations.  It found that even when the EPA knew of significant violations, it did not take action to correct the problem.  

The wood heater manufacturing and test lab industry is a collegial community where members rarely publicly criticize other members, even when major violations of the EPA regulations are widely known. However, manufacturers often relay private complaints about their competitors to the EPA, putting the EPA on notice of a wealth of compliance issues.

“We call on EPA leadership to provide more resources toward the wood stove program and address systemic enforcement issues,” said John Ackerly, President of the Alliance for Green Heat. “Its also vital for the public to know that pellet stoves are not involved in much of this controversy and that many wood stove manufacturers make good products, follow the law and are being undercut by those who knowingly skirt regulations,” Mr. Ackerly said.

Over the last 15 years, the only entity that has consistently published specific instances of non-compliance is the Alliance for Green Heat (AGH) in its monthly newsletter, and on its website.  Like the EPA, AGH is often contacted by industry members who are troubled by the conduct of other members.  The OIG listed five instances of abuse that the EPA overlooked and failed to take sufficient action, but there are scores more.  For instance, the internet continues to be rife with the sale of uncertified wood heaters, including outdoor wood boilers, which the EPA has known about for years, and appears not to have done anything.

  

US Stove sold 4,321 stoves before they were certified

This week’s report from the OIG follows up on several high-profile cases that AGH has pressed the EPA to address, including widespread fraud at US Stove Company which the EPA has been silent on for 5 years. In that case, an employee of US Stove was outraged and blew the whistle on his company.  US Stove then sued the whistleblower, getting a Temporary Restraining Order (TRO) against him to shut him up, which the local Tennessee court said was “in the public interest.” 

 This week’s OIG report described how US Stove manufactured and sold 4,321 stoves before they were certified, and d859 of them were sold even before the test lab started testing the unit. Though the EPA had all of these details, it did lead to further action.

The stove in question was never officially recalled by the Consumer Product Safety Commission.  A list of wood and pellet stove recalls can be found here.

A second whistleblower came forward, providing extensive details of fraud to the EPA, imploring them to take action.  That person wrote: “To those of us who refused to cooperate with this fraud [at the US Stove Company], we had hoped that the EPA would step in, enforce its regulations, and thus provide some level of protection and dignity to whistleblowers. I expect US Stove may come after me, and possibly file a lawsuit against me, as they did with the first whistleblower. The company has dragged that man through the mud, and forced him to hire expensive lawyers, just because he was willing to stand up for EPA regulations.”

False advertising of efficiency

Another major issue that AGH has pursued over the years is false or misleading advertising of efficiency levels, often telling consumers that the unit is eligible for the IRS tax credit, which requires stoves to be 75% efficient, using the higher heating value (HHV). In one case, a test lab listed the stove at 70% efficient, but the manufacturer told consumers it was 75% efficient and eligible for the tax credit. The EPA sent the manufacturer a cease-and-desist request via email, which the manufacturer did not act upon.  The OIG report said the EPA could have revoked the certification of the stove but has not taken further action.  

 

False and misleading efficiency advertising was widespread up until 2021, when most manufacturers began to advertise the efficiency as reported by test lab, and listed in the EPA database of certified stoves. US Stove continued to falsely represent some of its units and declined to comment on the record. Stove Builder International, a large Canadian manufacturer insists that various interpretations of efficiency were acceptable until and unless the IRS defined “efficiency” more clearly. For example, some experts argue that if a stove reaches 75% efficiency on any official test burn, it can qualify even if the average efficiency of all four burns is less than 75%.

 

While the OIG vigorously raises the issue of false advertising of stove efficiencies, it is far from clear whether OECA even believes it has the authority to address efficiency.  Efficiency testing became mandatory in 2020 but the EPA began listing efficiencies in 2012. The EPA does not regulate efficiency, as most European countries do, allowing stoves as low as 51% efficient to be certified.

 

EPA lab served as own third-party certifier

One of the 5 incidents of concern in the OIG report included an EPA approved lab serving as its own third-party certifier of a test report it has produced.  Again, the EPA knew about this but did not revoke the certification and “the lab remained approved by the EPA.”  

 

Test labs are allowed to be third party certifiers and most of them are.  However, they cannot certify the results of stoves tested in their own lab.  PFS-TECO, Intertek, OMNI, RISE (Sweden) and SZU (Czech Republic) are both test labs and third-party certifiers.  PolyTest (Canada), ClearStak and the Danish Technological Institute are approved test labs but are not third-party certifiers. 

 

Deviation from test methods

A fourth concern raised by the OIG, which has already been resolved, involved Lamppa manufacturing who makes Kuuma wood furnaces.  Lamppa had obtained an alternative test method, but the test lab deviated from that method, due to complications.  The manufactured disclosed the deviation and explained why, and the EPA certified it anyway.  After 5 years, the EPA informed Lamp it would not recertify the unit, and Lamppa had to retest and recertify the unit.  

 

Recommendation to the EPA

 

The OIG listed several significant recommendations, some of which could be incorporated into the next set of wood stove regulations, known as New Source Performance Standards (NSPS), which the EPA is currently working on.

 

·      Including a federal criminal false statement clause into the wood heater certification application process, which would require manufacturers, but not necessarily retailers, to not make false statements in their advertising.

·      Develop procedures to revoke the approval of test labs that do not follow NSPS requirements.

·      Develop procedures to revoke the certification of wood heaters that do not coply with NSPS requirements.

·      Inform the OIG of investigations into fraud or abuse of the wood heater NSPS.

Inspector General investigating EPA’s oversight of its residential wood heater program

On October 22, 2021, the EPA’s Office of the Inspector General announced it was launching an investigation into the EPA’s residential wood heater testing and certification program. The memo announcing the investigation was directed at both the Office of Enforcement and Compliance (OECA) based in DC and the Office of Air and Radiation (OAR) whose staff is mainly based in Triangle Park, North Carolina. The report is scheduled to be published sometime next year.

The Office of the Inspector General is “an independent office within the EPA that helps the agency protect the environment in a more efficient and cost-effective manner.” It identifies areas it believes need investigation and issues a public report with recommendations. While it does not have enforcement power, the EPA is expected to take the Office's recommendations seriously. There can be disagreements over priorities and that is already happening in the water program and elsewhere. The OIG also submits semiannual reports to Congress. In the event that the EPA ignores any of the recommendations made by OIG, it is possible that the agency can be pressured to address them through hearings, appropriations riders or funding. The EPA OIG can also uncover criminal behavior, which would be addressed accordingly by the U.S. Attorney's Office.

 

More specifically, the memo announcing this evaluation says, “Our objective is to determine whether EPA effectively uses its oversight and enforcement authority to ensure that all residential wood heaters reaching consumers are properly tested and certified in accordance with established standards. … We may also choose to include a sample of regions in our evaluation and to conduct work at laboratories and third-party certifiers in selected regions.”

A current ad for uncertified
outdoor wood boilers

Before publicly announcing this evaluation, the OIG contacted the Alliance for Green Heat on Oct. 13, 2021 and held a conference call with AGH on Oct. 21. For years, AGH has been raising alarm bells about the lack of EPA enforcement in a number of areas, including the numerous companies that continue to manufacturer and sell outdoor wood boilers. AGH has often contacted the EPA Office of Enforcement and published stories on our newsletter on companies who make and/or distribute uncertified residential central wood heaters, including ACME (Missouri), EZBoiler (Michigan), Hyprotherm (Arkansas) and MBTEK (Pennsylvania distributor of Polish appliances). AGH has spoken with most of the companies by phone and they say that they have never been contacted by the EPA or a state agency about certification issues.

AGH also raised EPA’s failure to contact the whistleblower regarding the credible allegations of fraud at US Stove Company, along with a number of other areas where enforcement action was needed.

The OIG’s evaluation is also believed to have been triggered by the NESCAUM report, Assessment of EPA’s Residential Wood Heater Certification Program, that found a “systemic failure of the entire certification process, including EPA’s oversight and enforcement of its requirements.” That report led the EPA to conduct its own review of the certification paperwork for all certified stoves. The EPA is contacting scores of companies to obtain missing information or for clarification. In some cases, it is requiring the company to have the stove tested again.

If you have evidence of misconduct or mismanagement regarding the EPA’s oversight of wood heater testing or certification, you can provide information using this form, and refer to case OSRE-FY22-0026.
