EPA issued a proposed Direct Final Rule, concerning formaldehyde emission standards for composite wood products, extending all of the TSCA Title VI compliance deadlines to account for the delays to the originally published effective date. The rule was published in the Federal Register May 24. The new compliance dates are as follows:
• Emissions, recordkeeping and labeling provisions – March 22, 2018
• Import certification – March 22, 2019
• Laminated products – March 22, 2024
The rule also proposes to extend the transitional period for CARB-certified third-party certifiers (TPCs) to March 22, 2019.
This proposed rule will enter into effect within 45 days of publication in the Federal Register if EPA does not receive any adverse comment within 15 days.
“The federal regulation that definitively addresses formaldehyde emissions from composite wood products sold in the United States was first published in the Federal Register on Dec. 12, 2016, by the U.S. Environmental Protection Agency. If properly enforced, the regulation can ensure that all products – both domestic and imported composite wood panels and the finished products containing them – meet the world’s most stringent standards for formaldehyde emissions. It also marks the culmination of over 30 years of product stewardship by the composite wood industry, which through voluntary efforts and consistent and progressive work with regulators, has successfully developed products that consistently meet or exceed these tough standards,” said Jackson Morrill, president of the Composite Panel Association.

One building stands out in the old logging town of Prince George, Canada. Encased in a sleek glass facade, the structure towers above most of its neighbors, beckoning from afar with the warm amber glow of Douglas fir. Constructed almost entirely from timber in 2014, the 8-story, 30-meter building is among the tallest modern wooden structures in the world. But it is more than an architectural marvel. As the home of the Wood Innovation and Design Centre at the University of Northern British Columbia (UNBC), it is also an incubator for wooden buildings of the future — and a herald for a movement that could help to tackle global warming.
The building is less like a log cabin and more like a layered cake, constructed from wooden planks glued and pressed together, precision cut by factory lasers and then assembled on site. All told, the university avoided the release of more than 400 tons of carbon dioxide by eschewing energy-intensive concrete and steel, and the building locks up a further 1,100 tons of CO2 that was harvested from the atmosphere by British Columbian trees. In total, that’s enough to offset the emissions from 160 households for a year.
Wooden construction has ancient roots, but only in the past two decades have scientists, engineers and architects begun to recognize its potential to stave off global warming. By substituting concrete and steel with wood from sustainably managed forests, the building industry could curb up to 31% of global carbon emissions, according to research by Chad Oliver, a forest ecologist at Yale University in New Haven, Connecticut. In time, such a shift could help humanity to pull CO2 out of the atmosphere, potentially reversing the course of climate change.
“It’s the plywood miracle,” says Christopher Schwalm, an ecologist at Woods Hole Research Center in Falmouth, Massachusetts. “This is something that could have a significant impact on the riddle that is global environmental change.”
