National Emission Standards for Hazardous Air Pollutants: Plywood and Composite Wood Products
The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the national emissions standards for hazardous air pollutants (NESHAP) for the Plywood and Composite Wood Products (PCWP) source category. Specifically, the EPA is finalizing maximum achievable control technology (MACT) standards in the form of emission limitations and work practices as appropriate for total hazardous air pollutants (HAP) (including acetaldehyde, acrolein, formaldehyde, methanol, phenol, propionaldehyde), non-mercury (non-Hg) HAP metals, mercury (Hg), hydrogen chloride (HCl), polycyclic aromatic hydrocarbons (PAH), dioxin/furan (D/F), and methylene diphenyl diisocyanate (MDI). Sources affected by the amendments include PCWP process units and lumber kilns located at facilities that are major sources of HAP emissions. These final amendments address the 2007 partial remand and vacatur of the 2004 final rule that promulgated the PCWP NESHAP (''2004 rule''). The final amendments also respond to issues raised in a petition for reconsideration regarding the 2020 residual risk and technology review (RTR) and other amendments to the 2020 PCWP NESHAP. This final rule is effective on 6 July 2026. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of 6 July 2026.

Proposed rule - The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Plywood and Composite Wood Products (PCWP), as required by the Clean Air Act (CAA). To ensure that all emissions of hazardous air pollutants (HAP) from sources in the source category are regulated, the EPA is proposing HAP standards for processes currently unregulated for total HAP (including acetaldehyde, acrolein, formaldehyde, methanol, phenol, propionaldehyde), non-mercury (non-Hg) HAP metals, mercury (Hg), hydrogen chloride (HCl), polycyclic aromatic hydrocarbons (PAH), dioxin/furan (D/F), and methylene diphenyl diisocyanate (MDI). The standards the EPA is proposing include emission limitations and work practices applicable for PCWP process units and lumber kilns located at facilities that are major sources of HAP emissions. This proposal responds to the 2007 partial remand and vacatur of portions of the 2004 PCWP NESHAP in which the EPA previously concluded maximum achievable control technology was represented by no control (i.e., no emissions reduction). This proposal also responds to or requests comment on issues raised in a petition for reconsideration the EPA received regarding the technology review and other amendments to the PCWP NESHAP the EPA finalized on 13 August 2020.

National Emission Standards for Hazardous Air Pollutants: Plywood and Composite Wood Products Residual Risk and Technology Review
Proposed rule - The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Plywood and Composite Wood Products (PCWP) to address the results of the residual risk and technology review (RTR) that the EPA is required to conduct under the Clean Air Act (CAA). The EPA is proposing to amend provisions addressing periods of startup, shutdown and malfunction (SSM); add provisions regarding electronic reporting; add repeat emissions testing requirements; and make technical and editorial changes. The EPA is proposing these amendments to improve the effectiveness of the NESHAP. While the proposed amendments would not result in reductions in emissions of hazardous air pollutants (HAP), this action, if finalized, would result in improved monitoring, compliance, and implementation of the rule.
