    The Environmental Protection Agency (EPA) has extended the comment periods for two notices originally published in the Federal Register last December and January. The new deadlines for submitting comments are now April 25, 2025, for one notice and April 16, 2025, for the other. These notices involve the draft national recommended ambient water quality criteria for certain chemicals and a draft sewage sludge risk assessment. The extension gives people more time to review and provide feedback on how these regulations might affect them.

    Simple Explanation

    The EPA is giving people more time to share their thoughts about how certain chemicals in water and sewage might affect health. People now have until mid to late April to say what they think.

    The Environmental Protection Agency (EPA) issued a correction to a notice previously published on December 26, 2024, in the Federal Register, regarding ambient water quality criteria. The error in Table 1's entry for the PFOA Organism Only Human Health Criteria (HHC) incorrectly reported a value of 0.00036 ng/L, which has been corrected to 0.0036 ng/L. The correction aims to ensure the published information accurately reflects EPA's standards for water quality. Comments on this correction are invited until February 24, 2025.

    Simple Explanation

    The EPA made a fix to a number in their water safety rules to make sure it's right. They changed a tiny number in their list from 0.00036 to 0.0036 to help keep the water safe for all of us.
