EPA Issues Prepublication Version of Final TSCA Title VI Technical Amendments

EPA issued today a prepublication version of the final technical amendments to TSCA Title VI.  In a press release on its website, EPA indicated that the amendments address the following:

  • Removing annual correlations between the Third-Party Certifier’s (TPC’s) chamber and the mill quality control chamber;

  • Allowing equivalence on like-size or similar model chambers at TPC lab and mill;

  • Averaging of emission test results from quarterly testing;

  • Establishing testing emission ranges;

  • Allowing for equivalence only if mill uses a TPC to conduct all testing;

  • Updating correlational coefficients and “r” value alternatives;

  • Updating the notification of an exceedance of quality control limit;

  • Updating NAF and ULEF exemption testing requirements;

  • Updating the ISO 17025-2017 and 17011-2017 voluntary consensus standards;

  • Updating text in the non-complying lot provisions;

  • Clarifying that labels on compliant products are required at point of entry in the United States; and

  • Clarifying the June 1, 2018 manufactured-by date following a court ruling in 2017.

After a brief initial review, it appears that EPA has addressed most of the issues cited by CPA and brought TSCA Title VI into greater alignment with CARB.  The amendments will become effective on the date of publication in the Federal Register.  CPA is reviewing the amendments in detail and will provide a more thorough analysis to members later this week.  See EPA Amendments.  More Info:  Jackson Morrill
