Cancer Chemical Ban: MN Leads Nation's Fight

Minnesota has once again demonstrated leadership in environmental protection, this time by paving the way for a nationwide ban on the toxic chemical TCE. This ban, which was previously on hold, has now moved forward to safeguard public health across the United States. The state's journey began nearly six years ago when WCCO first reported on the dangers of TCE emanating from a manufacturing plant in White Bear Township.

Residents, concerned about over 15 years of exposure to the carcinogenic chemical, formed the Neighborhood Concerned Citizens Group. This group, alongside individuals affected by cancer and chronic illnesses, actively lobbied lawmakers. Their persistent efforts culminated in 2020 when Minnesota became the first state to enact a ban on TCE, a chemical commonly used as a degreaser.

The groundwork laid in Minnesota proved instrumental in advancing a federal ban. In late 2024, the Environmental Protection Agency issued a rule to manage TCE risks nationwide. Although briefly paused for review, the rule is now active, phasing out most uses of TCE, with limited exceptions for nuclear fuel manufacturing expected to comply by 2028.
