STORM KING PLANT GIVEN CLEARANCE BY STATE AGENCY
Environmental Conservation Dept certifies that Contol Edison's Storm King pumped‐storage plant on Hudson River will not violate water quality standards; Comr Diamond's statement says project has been certified on condition that it will be halted immediately in event of contravention with water standards; Scenic Hudson Preservation Conf repr scores decision; says case will be carried to Sup Ct if Appeals Ct fails to reach favorable ruling on its suit against FPC approval of plant; environmentalists charge that project would draw so much water out of river that salt water would intrude and contaminate fresh water supplies
