Municipality does not have Article III standing to challenge a second municipality's use of a very large pipe to build a second sewer nearby, since, although the large pipe might someday be used to offer a competing sewer option to a factory in the first municipality, there is insufficient showing that it would happen within the timeframe of the federal noncompete statute.
Dissent: Standing, since judicial resolution would provide present financial certainty. (But would deny on merits.)
