The Minnesota Department of Health (MDH) regularly evaluates chemicals using the best available scientific information. The Minnesota Pollution Control Agency (MPCA) uses MDH’s evaluation and guidance as a tool to protect human health and the environment.
Recently, MDH completed an updated evaluation of the existing air risk assessment advice for trans-1,2-dichloroethylene (tDCE), which was developed specifically for Water Gremlin, located in White Bear Township. The change lowers the guidance value for safe lifetime exposure to tDCE in outdoor air and introduces a new guidance value for shorter exposures up to eight years.
Future tDCE emissions will be limited as appropriate for protection of human health. MPCA will continue to monitor tDCE around the facility and will hold Water Gremlin accountable for any new limits that may be imposed. The MPCA will use this new public health information to guide its permit development for Water Gremlin. For more information, visit the Water Gremlin web page.
