On April 25, 2017, the U.S. Environmental Protection Agency (EPA) issued two notices in the Federal Register expressing its determination that 28 new chemical notifications are “not likely to present an unreasonable risk of injury to health or the environment.”  82 Fed Reg. 19044 (Statement of Findings for December 2016); 82 Fed. Reg. 19046 (Statements of Findings for February 2017).  The statements of findings list premanufacture notices (PMN) and microbial commercial activity notices (MCAN) regarding new polymer and biodegradable chemicals submitted to EPA under Section 5 of the Toxic Substances Control Act (TSCA).  The notices listed in the December 2016 statement of findings are:

The notices listed in the February 2017 statement of findings are:

Commentary

The publication of these two notices fulfills EPA’s obligation under TSCA Section 5(g) to publish its findings; all of these determinations had previously been posted to the EPA website.  It is to EPA’s credit that EPA has made its determinations public as soon as practicable by posting those determinations on its website.  We recognize that publication in the Federal Register often lags behind EPA’s decisions because of resource constraints and competition with other Federal Register notices.  We are pleased to see new chemicals cleared for production.

Nevertheless, EPA’s pace of approving new chemicals for the marketplace has slowed tremendously since enactment of TSCA reform.  Furthermore, these notices do not provide any line of sight on the reasons contributing to the delays, or EPA’s resolution of these issues.  To date, EPA has only published its final determinations for substances with low concerns for heath and ecological hazards.  With only 28 new chemicals approved from the time period of December 1, 2016, to February 28, 2017, EPA will need to work much faster to even come close to its annual average number of 700-800 PMN reviews and keep the backlog of cases under review from continuing to grow.
