EPA is publishing this final rule to amend the formaldehyde standards for composite wood products regulation. EPA is publishing these amendments to address certain technical issues and to further align the final rule requirements with the California Air Resources Board (CARB) Airborne Toxic Control Measures (ATCM) Phase II program. Addressing these technical issues will add clarity for regulated entities. These revisions to the existing rule will also streamline compliance programs and help to ensure continued smooth transitions for supply chains to comply with the requirements associated with regulated composite wood products.
