The US Environmental Protection Agency (EPA) has updated its list of standards for formaldehyde emission in composite wood products and clarified a technicality to allow panel manufacturers to correlate their quality control methods to either the large or small chamber. This final rule (83 FR 5340) became effective on February 7, 2018.

In October 2017, the US Environmental Protection Agency (EPA) published a Direct Final Rule (DFR, 82 FR 49287 [1]) and a Proposed Rule (PR, 82 FR 49302 [2]) to update a series of voluntary consensus standards that were referenced in the formaldehyde standards for composite wood products regulations. That DFR was subsequently withdrawn following receipt of an adverse comment.

On February 7, 2018, the EPA published a Final Rule in the Federal Register (83 FR 5340 [3]) to update the references for multiple voluntary consensus standards that were incorporated in the formaldehyde standards for composite wood products final rule of December 2016 (81 FR 89674 [4]). This latest Final Rule contains, inter alia, the following important changes:

  • Revising 14 standards (see Table 1) to reflect the latest editions that are in use by the composite wood industry.

  • Updating a technical revision to allow panel manufacturers to correlate their quality control methods to ASTM E1333-14 or, upon demonstrating equivalence, ASTM D6007-14.

  • Clarifying that data generated from December 12, 2016 from a panel manufacturer’s QC test method may be used to certify compliant composite wood products under the TSCA Title VI program until a new annual correlation is required

  • Informing that beginning February 7, 2018, data used to establish correlations must be generated using ASTM E1333-14 or ASTM D6007-14 and the panel manufacturer’s QC approved test method. 

This Final Rule became effective on the date of its publication in the Federal Register. That was February 7, 2018.

Highlights of the list of revised 14 standards are summarized in Table 1.
