National Emission Standards for Hazardous Air Pollutants: Plywood and Composite Wood Products; Effluent Limitations Guidelines and Standards for the Timber Products Point Source Category; List of Hazardous Air Pollutants, Lesser Quantity Designations, Source Category List

摘要

This action promulgates national emission standards for hazardous air pollutants (NESHAP) for the plywood and composite wood products (PCWP) source category under the Clean Air Act (CAA) and revisions to the effluent limitations, guidelines and standards for the timber products processing source category under the Clean Water Act (CWA). The EPA has determined that the PCWP source category contains major sources of hazardous air pollutants (HAP), including, but not limited to, acetaldehyde, acrolein, formaldehyde, methanol, phenol, and propionaldehyde. These HAP are associated with a variety of adverse health effects. These adverse health effects include chronic health disorders (e.g., damage to nasal membranes, gastrointestinal irritation) and acute health disorders (e.g., irritation of eyes, throat, and mucous membranes, dizziness, headache, and nausea). Three of the six primary HAP emitted have been classified as probable or possible human carcinogens. This action will implement section 112(d) of the CAA by requiring all major sources subject to the final rule to meet HAP emission standards reflecting the application of the maximum achievable control technology (MACT). The final
