Composite Wood Products Advisories

The Airborne Toxic Control Measure (ATCM) to control formaldehyde emissions from composite wood products was approved on April 18, 2008, by the Office of Administrative Law.  The regulation has been filed with the Secretary of State and is codified into Title 17 of the California Code of Regulations, and is now effective.

Advisories and guidance related to the Composite Wood Products ATCM are published as needed to provide information on the ATCM. To save resources, all advisories are distributed electronically through the Composite Wood Products ATCM email list.
