MPART Meets to Take Action on Developing PFAS MCL

The Michigan PFAS Action Response Team (MPART) met today and approved the creation of a Science Advisory Workgroup to review existing and proposed health-based drinking water standards from around the nation to inform the rulemaking process for Maximum Contaminant Levels for Michigan. 

“This is a big step in Michigan’s collaborative approach to protecting public health by reducing exposures to PFAS in drinking water,” said MDEQ Director Liesl Clark.  “Enforceable drinking water standards will help facilitate the actions of local water supplies and state government to ensure public water supplies are as safe as possible.”  Standards represent one of several tools in the state’s PFAS toolkit to protect the public health of Michigan residents.

The Science Advisory Workgroup will consist of 3 or more scientists with expertise in PFAS chemicals and their impact on human health.  The experts in toxicology, epidemiology, and risk assessment will be named shortly.

MPART approved a detailed charge for the Science Advisory Workgroup with a deadline of July 1, 2019, for recommending the health-based values.  The health-based values will be provided to MDEQ who will, with the input of stakeholders, create administrative rules. The draft rules are expected to be developed by October 1, 2019 and adopted in the spring of 2020.

Governor Gretchen Whitmer directed the MDEQ to start rulemaking on March 26, 2019. The MDEQ submitted a Request for Rulemaking to the Office of Regulatory Reinvention; that request was approved on March 28, 2019.  Today’s MPART meeting was the next important step in developing drinking water standards for PFAS.

The MDEQ is committed to transparency and will ensure multiple opportunities for affected communities and stakeholders to have input on proposed PFAS standards.  Look for additional information about the rule making process and other materials from today’s MPART meeting on the MPART website:
