The Town of Porter has overbilled Fort Niagara State Park by $152,900 for sewer service since 2014, according to a state audit released Thursday.
In 1970, State Parks signed a contract to use Porter's sewers. In 1996, the town changed the billing basis from the park's share of the total sewer flow to its amount of water use, but the contract never was altered. The sewage is treated in Lewiston, which in 2013 started billing Porter for debt service on sewer upgrades.
Porter passed those charges along to State Parks and another user, the Village of Youngstown. State Parks kept paying, but Youngstown refused. A subsequent town-village lawsuit remains unsettled.
Porter Supervisor Merton K. Wiepert told the State Comptroller's Office discussions are planned with State Parks, but he did not acknowledge overbilling.
