EPA Finalizes Emission Standards for Plywood and Composite Wood Products Industry

The U.S. Environmental Protection Agency (EPA) has finalized amendments to emission standards for hazardous air pollutants (HAP) in the plywood and composite wood products (PCWP) industry. - Government Buyer: - U.S. Environmental Protection Agency (EPA) - Scope and Applicability: - Applies to 219 major source facilities manufacturing PCWP and kiln-dried lumber - Regulates process units such as lumber kilns, dryers, refiners, presses, and material handling units - Products/Processes Regulated: - Fiberboard mat dryers, press predryers, atmospheric refiners, reconstituted wood product presses (using MDI resin), tube dryers, coating operations, direct wood-fired dryers, lumber kilns, resinated material handling units, digesters, fiber washers, and log vats - Emission limits set for specific pollutants: acetaldehyde, formaldehyde, methanol, methylene diphenyl diisocyanate (MDI), mercury, hydrogen chloride, polycyclic aromatic hydrocarbons (PAH), dioxin/furan, and others - Numeric emission limits and work practice standards detailed for each process unit - Unique/Notable Requirements: - Maximum Achievable Control Technology (MACT) standards for a wide range of HAPs - Work practice standards for certain units (e.g., O&M plans, annual burner tune-ups, temperature/moisture monitoring, use of non-HAP resins) - Continuous monitoring, recordkeeping, and periodic performance testing (every five years) - Compliance deadlines vary by source construction date (existing vs. new/reconstructed sources) - No specific OEMs or commercial vendors are named, as this is a regulatory action rather than a procurement opportunity.

Description

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. The amendments include maximum achievable control technology (MACT) standards for various hazardous air pollutants including acetaldehyde, acrolein, formaldehyde, methanol, phenol, propionaldehyde, non-mercury HAP metals, mercury, hydrogen chloride, polycyclic aromatic hydrocarbons, dioxin/furan, and methylene diphenyl diisocyanate. The affected sources include PCWP process units and lumber kilns at facilities that are major sources of HAP emissions. These amendments address previous legal and technical issues including a 2007 partial remand and vacatur of the 2004 final rule and respond to issues raised in a petition for reconsideration regarding the 2020 residual risk and technology review and other amendments to the 2020 PCWP NESHAP.
