Hawaii Keeps State Drinking Water Program
Hawaii adopted regulations to implement the Federal Ground Water Rule and the EPA approved that revision, so Hawaii can continue operating its own Safe Drinking Water Act primacy program. The approval means the state's groundwater protections are at least as strict as federal rules, and the EPA notes no extra costs or delays are expected; the determination takes effect following the public hearing opportunity and the procedures in the Supplementary Information.
