FERC (i) addresses arguments raised by Seabrook’s request for rehearing of the Seabrook Dispute Order (denied by operation of law), modifying the discussion but  reaching same result; and (ii) terminates the 206 proceeding instituted in Docket No. EL21-94 (determining that its findings in the Seabrook Dispute Order, that Seabrook must replace the breaker at Seabrook Station pursuant to the terms of its LGIA, render the 206 investigation moot).
