In an August 8 press release U.S. EPA says that it has eliminated a backlog of pending reviews under the TSCA Section 5 program that existed at the time of the enactment of last year's revision of the Act. According to EPA the backlog has been reduced from over 600 pending cases as of June 22, 2016, the date the new law was signed, to what the agency describes as a "normal active workload" of 308 cases.
Section 5 under both the prior and current law requires chemical manufacturers and importers to file certain notices, depending on the particular action contemplated. These include preliminary manufacturing notices (PMNs) for chemicals introduced for the first time, Significant New Use Notices (SNUNs) for existing chemicals for which EPA has determined that a proposed new use could be significant, and a Microbial Commercial Technology Notice (MCAN) for certain microbial uses. Under Section 5 EPA also reviews applications for exemptions from Section 5, including a Low Volume Exemption (LVE) and a Low Exposure Exemption (LoREX).
Between the June 22 effective date of the new law and August 1 of this year, EPA states that it has completed review of 1,022 cases. These include 490 PMN/MCAN/SNUN reviews and 532 exemption requests. That has resulted in the reduction of the backlog from over 600 pending cases to the current 382 such cases. Of the latter amount EPA is waiting for further testing and long-term information from the person giving the notice. That yields the 308 pending cases touted by EPA in its press release.
EPA Administrator Scott Pruitt attributes the backlog elimination to a conscious effort on the part of both EPA staff and stakeholders working with the agency. EPA is also touting the following operating principles as part of its ongoing commitment to improve the Section 5 process:
The EPA press release also commits the agency to a number of additional actions to promote continued improvement of the TSCA new chemicals program (including the assignment of more staff to the program) and to implementation of specified actions to make EPA's decision making under the program more transparent.
