{"abstract":"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.","action":"Final rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/07/06/2026-13550.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"63","title":40}],"citation":"91 FR 41410","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on July 6, 2026.
