Title: ●Procedural Rule: Review of CBI Claims for the Identity of Chemicals on the TSCA Inventory--Amended TSCA Section 8(b)(4)(C) 

On June 22, 2016, President Obama signed into law the Frank R. Lautenberg Chemical Safety for the 21st Century Act which amends the Toxic Substance Control Act (TSCA), the Nation's primary chemicals management law. A summary of the new law, which includes much needed improvements to TSCA, is available at This particular rulemaking effort involves the revised TSCA section 8(b)(4)(C), which requires EPA to issue a final rule within 1 year of completing a "reset" of the TSCA Inventory that establishes a plan to review all claims to protect the specific chemical identities of chemical substances on the confidential portion of the active Inventory. The rule must require all manufacturers or processors asserting CBI claims for the identities of chemicals on the active Inventory to substantiate those claims in accordance with TSCA section 14 unless the manufacturer or processor already substantiated the claim in a submission to EPA that was subsequently approved during the previous 5-year period. Approved CBI claims will generally be valid for 10 years.
