siting, building, and operating a facility] be borne by the waste generators” who use it); Brief for Plaintiffs in Sur-reply to North Carolina’s Reply 1, n. 1 (noting that a disposal facility in South Carolina collected over $47 million in fees in 2008).
Of course, as the majority notes, South Carolina’s withdrawal from the Compact could have affected North Carolina’s ability to “recoup” its “construction costs.” Ante, at 18. But, as far as I am aware, North Carolina did not seriously seek to amend the Compact when South Carolina departed (even though the State had sought and obtained an amendment previously, see ante, at 20, n. 4; Brief for North Carolina in Reply to Exceptions By Plaintiffs to Reports of the Special Master 27), nor has it argued to this Court that South Carolina’s departure voided its contractual obligations. Indeed, there is evidence in the record indicating that, even after South Carolina left the Compact, North Carolina continued to believe that the operation of a waste disposal facility presented a substantial financial opportunity. App. 255, 266 (Attachment to Letter from John H. MacMillan, Executive Director, North Carolina Low-Level Radioactive Waste Management Authority, to Richard S. Hodes, M.

I thus cannot conclude, as the majority does, that the Compact’s rotational design, as I understand it, is “foolish.” Ante, at 18. Rather, the Compact’s structure represents what, in my view, was a understandable decision by the contracting States, all of whom needed a waste disposal facility, to bind themselves together so that each would take a turn “bear[ing] the cost of building” the necessary facility.
