Former Sioux City Wastewater Treatment Plant Superintendent, Jay Earnest Niday Sentenced to Federal Prison for Violating the Clean Water Act
Rigged Environmental Testing for Years
(STL.News) The former Superintendent of the Sioux City Wastewater Treatment Plant, who conspired to cheat on environmental testing at the plant, was sentenced on April 1, 2021, to three months in federal prison.
Jay Earnest Niday, age 63, from Sergeant Bluff, Iowa, received the prison term after a October 6, 2020 guilty plea to one count of conspiracy and one count of knowingly falsifying, tampering with, and rendering inaccurate a monitoring device or method required to be maintained under the Clean Water Act.
The evidence at Niday’s guilty plea and sentencing hearings showed that Niday was employed as the Superintendent of the Sioux City Wastewater Treatment Plant (WWTP). The WWTP is a large regional sewage treatment plant for wastewater from industrial, commercial, and residential sources throughout Siouxland, including Sergeant Bluff, Iowa, South Sioux City, Nebraska, North Sioux City, South Dakota, and Dakota Dunes, South Dakota. The WWTP’s more than 20 industrial users produce a large volume of high-strength wastewater. Under a Clean Water Act (CWA) permit, the WWTP was required to treat wastewater before discharging it into the Missouri River, which has heavy local recreational use.
