Withdrawal From Federal Regulations of Human Health Water Quality Criteria Applicable to Idaho

요약

In 1992, EPA promulgated federal regulations establishing water quality criteria for toxic pollutants for several states, including Idaho (40 CFR 131.36). Idaho has now adopted, and EPA has approved, human health water quality criteria. In this action, EPA is amending the federal regulations to withdraw all human health criteria applicable to Idaho with the exception of the human health criteria for arsenic. EPA is withdrawing its human health criteria applicable to Idaho without a notice and comment rulemaking because the State's human health criteria (except for arsenic) are identical to the federal criteria. In a separate action elsewhere in this issue of the Federal Register, EPA is proposing to withdraw the federal human health criteria for arsenic and is taking public comment on that proposed action.
