Withdrawal of Federal Antidegradation Policy for All Waters of the United States Within the Commonwealth of Pennsylvania

요약

EPA is proposing to withdraw the federal antidegradation policy for all waters of the United States within the Commonwealth of Pennsylvania. We will withdraw the federal antidegradation policy to allow Pennsylvania to implement its own antidegradation policy. Pennsylvania has adequately demonstrated that its antidegradation policy protects all waters of the United States within the Commonwealth at a level consistent with the federal requirements. Therefore, the federal antidegradation policy is redundant. In the "Rules and Regulations" section of this Federal Register, we are withdrawing the federal antidegradation policy for waters within the Commonwealth of Pennsylvania as a direct final rule without a prior proposed rule. If we received no adverse comment, we will not take further action on this proposed rule.
