The operator of a metal shredding facility in north Minneapolis agreed to shut it down permanently Monday after admitting to altering and inaccurately recording pollution readings over the summer.
A legal settlement, filed Monday in Ramsey County District Court, marked an end to a bitter and yearslong effort by North Side residents and environmental activists to move Northern Metal Recycling out of their neighborhood. Many blamed the high levels of air pollution around the shredder for serious health problems, including heart attacks, bronchitis and asthma.
The shredder ceased operation Monday evening, according to the Minnesota Pollution Control Agency (MPCA).
Minnesota Attorney General Keith Ellison, who represented the MPCA in the case, called the settlement "a win for all the people of Minnesota, especially the people of north Minneapolis who've been fighting for community health and environmental justice for years."

The company had been ordered to stop shredding at the facility, located just south of Lowry Avenue along the Mississippi River, by Aug. 1 in a separate agreement with the MPCA in 2017. But a last-minute ruling by Ramsey County District Judge John Guthmann allowed the company to stay in operation past that date as it finished a new facility in Becker, Minn.
Then on Aug. 1, a company employee, William Hodgeman, reached out to the MPCA, according to court documents. Hodgeman, whose job it was to record readings for the facility's pollution control equipment, said he was told by Northern Metal's management not to write down readings that exceeded the company's air emissions permit.
Information provided by Hodgeman and investigated by the MPCA — and confirmed by Monday's settlement — showed that readings from pollution filters were altered eight times over the summer, including by using white-out ink. In at least seven cases, readings that would have required corrective measures were changed to numbers that were below the action level, according to the settlement.
"The gravity of Northern Metals' violations could not be more serious," the state argued in the filing detailing the whistleblower's account. "The willfulness and number of falsifications demonstrates that Northern Metals' conduct was not an aberration — but rather an intentional, regular, and routinized process of falsification of its Records."
