Minnesota's top pollution authority is casting doubt on the accuracy of an EPA report that found years of Clean Air Act violations at an iron foundry in South Minneapolis.
Katrina Kessler, commissioner of the Minnesota Pollution Control Agency, said in an interview Monday that the state has no evidence Smith Foundry sent elevated levels of lung-damaging fine particulate matter into the neighborhood.
"The data that we have ... show that there is not a violation of the permit, there is not an exceedance of the air standards in that neighborhood," Kessler said. "We are certainly working with the EPA to understand the data that they are using to come to that conclusion."
The revelations from the EPA's inspection, first reported by the Sahan Journal, sparked a wave of anger in East Phillips, a neighborhood that has a history of pollution and where the foundry has made iron castings on E. 28th Street for a century.
In a surprise visit to Smith in late May, the EPA said it found visible particulates inside, building up on tables and escaping through open doors and windows. Inspectors recorded cracked, broken and rusted ductwork and a malfunctioning air filter. The agency later determined that Smith had been emitting fine particulates at rates nearly or more than double what was allowed each year since 2018. Particulate matter is a dangerous kind of pollution that can cause heart attacks, asthma and chronic health conditions.
State Rep. Aisha Gomez, DFL-Minneapolis, who represents some neighborhoods near the foundry, said she doesn't understand how the MPCA missed longstanding and seemingly obvious violations in a facility that, by state law, should receive extra scrutiny.
"This is a disappointment and it's an embarrassment and it's an insult," Gomez said. "This is an indication that they're asleep on the job. They owe our communities an explanation about why it is that it took an EPA surprise inspection to come and do the job that we thought they were doing all along."
But MPCA officials insisted they could not reproduce the calculations that EPA used to determine Smith broke emission rate limits and are trying to understand how the EPA reached its conclusions. Frank Kohlasch, MPCA assistant commissioner for air and climate policy, said it's possible the feds are mixing up emissions numbers that represent part of the facility and all of the facility.
