Emission Standards for Hazardous Air Pollutants: Plywood and Composite Wood Products; 
(32 page(s), in Eng lish) 
6. Description of content:  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, acrole in, 
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 G/TBT/N/USA/1529/Rev.1  
 
- 2 - 
 
  regarding the technology review and other amendments to the PCWP NESHAP the EPA 
finalized on 13 August 2020.  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Protection of the environment
