Proposed Revisions to SNURs under TSCA Raise Concerns
The U.S. Environmental Protection Agency (EPA) proposed on July 28, 2016, revisions to the regulations governing significant new uses of chemical substances under the Toxic Substances Control Act (TSCA) with revisions to the Occupational Safety and Health Administration’s (OSHA) Hazard Communications Standard (HCS) occasioned by OSHA’s March 2012 final rule modifying the HCS to conform to the United Nations’ (U.N.) Globally Harmonized System of Classification and Labelling of Chemicals (GHS), changes to OSHA’s Respiratory Protection Standard, and the National Institute for Occupational Safety and Health (NIOSH) respirator certification requirements pertaining to respiratory protection of workers from exposure to chemicals. EPA states that it is also proposing changes to regulations based on issues that it identified, as well as issues raised by public commenters, for significant new use rules (SNUR) previously proposed and issued under these regulations. Additionally, EPA claims to propose a “minor” change to reporting requirements for premanufacture notices (PMN) and other TSCA Section 5 notices. EPA states that it expects the changes “to have minimal impacts on the costs and burdens of complying, while updating the significant new use reporting requirements to assist in addressing any potential effects to human health and the environment.” Comments are due September 26, 2016.
The revisions include:
- Proposed Changes to 40 C.F.R. Section 721.63, Protection in the Workplace;
- Proposed Changes to 40 C.F.R. Section 721.72, Hazard Communication Program;
- Clarification of the Use of 40 C.F.R. Section 721.80, Industrial Commercial and Consumer Activities;
- Proposed Changes to 40 C.F.R. Section 721.91, Computation of Estimated Surface Water Concentrations: Instructions;
- Proposed Changes to 40 C.F.R. Section 721.11, Determining Whether a Chemical Substance or a Specific Use Is Subject to This Part When the Chemical Substance Identity or Significant New Use Is Confidential;
- Proposed Changes for Submission of SDS(s) with PMNs, SNUNs, Low Volume Exemptions (LVE), Low Release and Exposure Exemptions (LoREX), and Test Marketing Exemption (TME) Applications; and
- Fixing Typographical Errors and Other Non-Substantive Changes.
Although the notice downplays them, the proposal raises significant and complex issues. There may well be good reasons for several of the proposed changes. The minimal discussion provided in the notice and the lack of adequate public debate having occurred prior to its issuance raise troubling questions about the legal basis for, scope of, and complexity of the proposed changes, some of which may apply retroactively. The confusion the proposal can be expected to cause could have been avoided had adequate discussion preceded its publication, or at the least EPA could have raised these issues in the proposed rule’s preamble to focus stakeholders’ attention appropriately.
