WASHINGTON – Today, April 19, 2024, the U.S. Environmental Protection Agency (EPA) is taking another step in its efforts to protect people from the health risks posed by exposure to “forever chemicals” in communities across the country. Exposure to per-and polyfluoroalkyl substances (PFAS) has been linked to cancers, impacts to the liver and heart, and immune and developmental damage to infants and children. This final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund, and will help ensure that polluters pay to clean up their contamination.

This final action will address PFOA and PFOS contamination by enabling investigation and cleanup of these harmful chemicals and ensuring that leaks, spills, and other releases are reported. This action builds on the recently finalized standards to protect people and communities from PFAS contamination in drinking water and represents the latest step the Biden-Harris Administration is taking to protect public health and welfare and the environment under EPA’s PFAS Strategic Roadmap and to prevent cancer before it starts through the Biden Cancer Moonshot.

In addition to the final rule, EPA is issuing a separate CERCLA enforcement discretion policy that makes clear that EPA will focus enforcement on parties who significantly contributed to the release of PFAS

Worker Exceeded Annual Extremity Dose Limit

Print View Posted on: 17 April 2024

Event Date: 22 February 2024 Event Type: Radiation Source Event Location: United States of America, Alton, IL / Alton Steel INES Rating: 2 (Final)

An employee received a dose of 0.95 Sv (95 rem) to the extremities (hands) due to improper handling and response to an incident involving a damaged 85.1 MBq (2.3 mCi) Co-60 source. This dose was estimated by the Illinois Emergency Management Agency and confirmed by the licensee. The source was initially damaged when molten steel flowed over the source housing, severing the source into at least two pieces. The smaller portion, estimated to contain approximately 2.0 MBq (53 uCi), was inadvertently withdrawn from its shielded housing, fused with solidified steel and later partially recovered by the employee. The remainder of the Co-60 source was found to have been covered in solidified steel that prevented its return to the shield. The employee used a 4-inch angle grinder in an effort to remove the solidified steel so it would fit back into the shield. Inspection findings indicate the employee used gloved hands to effect recovery
