ALBANY, N.Y. -- Gov. Andrew Cuomo announced late Monday evening he has ordered the State Department of Environmental Conservation (DEC) to investigate a black, smelly discharge into the Niagara River on Saturday.

Cuomo's office said via a news release the DEC was not given notice of the discharge by the Niagara Falls wastewater treatment plant.

The Niagara Falls Water Board Executive Director Rolfe Porter told 2 On Your Side the discharge was the result of some work to maintain one of the plant's sediment tanks.

The governor's office says there could be a potential penalty of up to $37,500 per violation of the state Water Quality Standards, which prevent discharges from impacting the smell, color or visible natural conditions of the Niagara River.

"Niagara Falls and the Niagara River are a world-class destination for tourists and we should not be polluting this unparalleled natural resource," Cuomo said via a statement.
