When the Legislature passed a law in May boosting protections for historically polluted neighborhoods, it marked the end of a years-long effort by environmental justice advocates and lawmakers.
But it was only the beginning for the Frontline Communities Protection Act, broadly known as the cumulative impact law. Now the Minnesota Pollution Control Agency (MPCA) is seeking public feedback on how to define and enforce the law, which will go into effect in April 2026.
The new law sets higher regulatory standards for businesses and industries that want to operate in diverse, historically polluted neighborhoods. According to state data, racist zoning and housing policies built a system in which communities of color faced higher levels of air pollution.
"Today, as a result, too many children are disproportionately exposed to harmful pollution," said Anna Hotz, who leads administrative rulemaking at the MPCA.
Hotz said the state will need help from the public to formally define key terms in the law. Environmental advocates want to be an active part of the rulemaking process.
"I think it's important that the next three years are closely watched," said B. Rosas, who works with the Minneapolis-based nonprofit Climate Generation.
Although initially proposed to cover the whole state, the cumulative impact law applies for now only to Rochester, Duluth and the seven-county Twin Cities metro area. Large swaths of those areas are considered environmental areas or fall within the mile buffer range established in the law, according to the MPCA.
The law requires the MPCA to consider historical levels of pollution when issuing new permits or renewing existing ones in neighborhoods that have been labeled environmental justice areas, where at least one of these conditions is met:
