The proposed rule constitutes EPA’s response to the remand of the Phase II existing facility rule and the remand of the existing facilities portion of the Phase III rule. In addition, EPA is also responding to the decision in Riverkeeper I and proposing to remove from the Phase I new facility rule the restoration-based compliance alternative and the associated monitoring and demonstration requirements. EPA expects this proposed regulation would minimize adverse environmental impacts, including substantially reducing the harmful effects of impingement and entrainment.
