Environmental news on water, TSCA, PFAS, and vehicle emissions
Rules aim at water contaminants
PFAS and lithium — EPA finalized the Fifth Unregulated Contaminant Monitoring Rule to establish nationwide monitoring for 29 per- and polyfluoroalkyl substances (PFAS) and lithium in drinking water. See the December 27 Federal Register final rule.
Lead — EPA announced that the January 2021 Lead and Copper Rule Revisions went into effect December 16, 2021, to support near-term development of actions to reduce lead in drinking water. However, the agency intends to finalize a new rule to strengthen the requirements of 40 CFR 141 by October 2024. For more information, refer to the December 17 Federal Register Notification of Conclusion of Review.
Latest TSCA news roundup
Science — EPA issued a TSCA protocol for reviewing and selecting scientific studies to inform risk evaluations. Learn more from the December 20 Federal Register notice.
HBCD — A draft revised risk determination finds that cyclic aliphatic bromide cluster, as a whole, presents an unreasonable risk of injury to health and the environment. See the December 29 Federal Register notice.
Asbestos — EPA issued a draft scope document for a risk supplemental evaluation of asbestos, including legacy uses and associated disposals. Learn more in the December 29 Federal Register notice.
PFAS — EPA granted a petition from six North Carolina health/environmental organizations to compel companies to conduct testing of certain PFAS. For details, see EPA’s TSCA Section 21 webpage.
PFAS foam: DOE sites to report all releases and not use for training
Effective Dec. 15, 2021, all Dept. of Energy (DOE) sites have new marching orders for releases/spills of aqueous film-forming foam (AFFF) containing PFAS. All such releases onsite or offsite must be reported to a DOE “occurrence reporting” system. DOE sites were already directed in September to stop using PFAS-containing AFFF for training purposes and to suspend disposal of PFAS until further notice. DOE fire protection personnel also must wear personal protective equipment when discharging PFAS-containing AFFF in a fire emergency. Refer to the December 7th DOE memo, Department of Energy (DOE) Guidance on Reporting Per- and Polyfluoroalkyl Substances (PFAS)-Containing Aqueous Film-Forming Foam (AFFF) Releases or Spills to the Environment.
Two rules target vehicle emissions
Two final rules take aim at greenhouse gas (GHG) emissions from mobile sources. The first rule issued December 30 revises 40 CFR 86 and 600 to tighten the GHG emissions standards for light-duty vehicles for 2023 and later model years. The second rule dated December 29 withdraws portions of the 2019 “SAFE I” rule that had sought to preempt states, including California, from issuing their own GHG emissions standards and zero-emissions vehicle mandates. Put another way, the latest action revises 49 CFR 531 and 533 to remove a roadblock to state actions that tackle vehicle GHGs.
