Comment submitted by Olivenhain Municipal Water District (OMWD)

Summary: The Olivenhain Municipal Water District supports the EPA's proposal to rescind regulatory determinations for PFHxS, PFNA, HFPO-DA, and PFBS. They argue that the rescission is necessary for a scientifically sound process, will reduce compliance costs for water providers, and that public health is sufficiently protected by existing PFOA and PFOS regulations.
