In re Petition of Missouri-American Water Company for Approval to Change its Infrastructure System Replacement SurchargeAnnotate this Case
Missouri American Water Company (MAWC) filed a petition to charge an infrastructure system replacement surcharge to its St. Louis County customers. The Public Service Commission (PSC) approved the petition. The Office of the Public Counsel appealed, arguing that the PSC lacked the authority to grant the petition because St. Louis County did not meet Mo. Rev. Stat. 393.1000-393.1006’s threshold population requirement at the time PSC approved the surcharge. The Office of the Public Counsel appealed. While the appeal was pending, MAWC and PSC reached an agreement establishing a new rate base that incorporated the costs of the MAWC projects for all then-existing surcharges. The Supreme Court dismissed this case as moot, holding (1) because the surcharge is no longer in effect and no effective relief may be granted, the issue as to whether MAWC can utilize the surcharge provisions of section 393.1003 is moot; and (2) the issues presented on appeal did not meet the requirements for an exception to the mootness doctrine.
