Seacoast Anti-Pollution League v. Costle
Facts
Public Service Company of New Hampshire sought approval for a once-through cooling system for the Seabrook Nuclear Power Plant under 33 U.S.C. § 1326(a) and (b). On remand, the Administrator ordered EPA staff to participate in a non-adversarial way, allowing them to testify, cross-examine witnesses, and prepare a technical summary without advocating a particular outcome. The system would draw 824,000 gallons of ocean water per minute through offshore intake structures and discharge heated water through a diffuser, with organisms drawn into the system not expected to survive. Petitioners argued that the neutral staff procedure was unlawful and that the record did not support findings regarding juvenile rainbow smelt, winter flounder larvae, and the intake location and design.
Issue
Whether the Administrator acted unlawfully by requiring EPA staff to participate neutrally rather than as advocates, and whether the Administrator's approval of the cooling system and intake location under 33 U.S.C. § 1326 was unsupported by substantial evidence or inadequately explained.
Rule
Absent law to the contrary, agencies enjoy wide latitude in fashioning their procedural rules. Under 33 U.S.C. § 1326, the Administrator's determinations that a design will assure the protection and propagation of a balanced, indigenous population and that intake structures reflect the best technology available must be upheld if supported by substantial evidence in the record. Under the APA, reviewing courts must take due account of the rule of prejudicial error, so failure to explain a noncritical order or conclusion is not reversible error absent prejudice or a need for review of that point.
