Withdrawal of Certain Federal Human Health and Aquatic Life Water Quality Criteria Applicable to Rhode Island, Vermont, the District of Columbia, Kansas and Idaho

In 1992, EPA promulgated Federal regulations establishing water quality criteria for toxic pollutants for several States, including Rhode Island, Vermont, the District of Columbia, Kansas and Idaho. These States have now adopted, and EPA has approved, human health and aquatic life water quality criteria. In this action, EPA is amending the Federal regulations to withdraw certain human health and aquatic life criteria applicable to these States. EPA is withdrawing its criteria applicable to these States without a notice and comment rulemaking because the States' adopted criteria are no less stringent than the Federal criteria.
