Per- and Polyfluoroalkyl Substances Michigan Department of Environmental Quality January 11, 2018

PFAS **Per- and Polyfluoroalkyl Substances** USEPA designation - national emerging contaminant PFAS - suite of chemicals, thousands of applications Used in industrial, food, and textile industries Characteristics Incredibly stable Break down very slowly Highly soluble Easily transferred through soil to groundwater

Statewide Concerns PFAS contamination identified in several locations in Michigan Currently – 14 locations, 29 sites Sources include: Current and former military installations Tanneries Plating operations Legal and illegal disposal sites Finding significant PFAS migration Water wells – test wells, residential, municipal, livestock

Michigan PFAS Action Response Team (MPART) Governor Snyder signed ED 2017-4 on November 13 Design: ensure comprehensive, cohesive, timely response to continued mitigation PFAS substances (PFAS) across Michigan Goal: provide cooperation and coordination among all levels of government

Challenges Test analysis time frame Unsettled science Funding Testing analysis time frame Approximately 12 private vendors do PFAS testing All out of state General turn-around 4-6 weeks, $500 Rush $1000 Unsettled science Some things we do know, Exposure pathway is ingestion only, not dermal Half-life is 2 to 9 years Activated carbon filters will work up to certain concentration levels Extremely high temperatures can break them down There is not consensus on Rate of dispersal in the environment ppt level at which filters should be used for consumptive water Human health impacts, animal impacts (livestock, pets, wild, fish) Bioaccumulation of long chain PFAS in animals and what that means to those consuming Funding Addressing these sites is staff intensive and analysis is costly. Need to take large number of samples (individual private wells and monitoring wells) to ensure public safety and characterize the plume. Also will require expensive remediation actions.

DEQ’s PFOA and PFOS 70 ppt Drinking Water Criterion PFAS criterion – 70 ppt PFOA and PFOS combined, established under Part 201 Took effect Wednesday, January 10, 2018 Allows MDEQ to: Mandate responsible parties conduct activities take legal action who doesn’t comply with MDEQ’s cleanup rules 70 ppt comes from the health advisory value set by EPA for PFOA and PFOS. 201 Rules 70ppt is also the value for PFOA/PFOS in the pending proposed 201 rule set. No concerns have been expressed to date with this value as part of the 201 rule process. Allows DEQ to Address contamination, reducing exposure to human health and the environment, and Pursue legal actions against those who don’t comply, including violation notices, lawsuits, etc.

Next Steps Stand up state laboratory capabilities MPART PFAS Multiagency Technical Workgroup Scientific Advisory Committee Local Public Health Advisory Committee Secure ongoing financial support Web site: www.michigan.gov/pfasresponse Laboratory Capabilities $1.4M in supplemental to finance lab equipment and supplies Currently in the process of working with vendors to order necessary equipment – should have a firm estimation on a date for opening within the month. MPART Direct work of individual departments to ensure coordination, alignment, and consistency 10 state departments, in coordination with local and federal officials across Michigan, are working together to ensure that the public health and safety of residents is protected while ensuring our environmental heritage is secure for generations of Michiganders to come. Receive regular updates on the status of site activities and legal actions Identify knowledge and resource gaps Ensure transparency regarding general and site specific information via Web site, community meetings, etc. Web site: www.michigan.gov/pfasresponse Provide report to the Governor and Cabinet on PFAS status and progress Scientific Advisory Committee led by Dr. David Savitz of Brown University’s School of Public Health and academic advisor to MPART convene Michigan and national PFAS experts to review available science and make recommendations for Michigan’s statewide response coordinate and review medical and environmental health PFAS science and develop evidence-based recommendations charged with completing their review and making recommendations within the next six months. Local Public Health Advisory Committee led by Dr. Eden Wells, chief medical executive with the Michigan Department of Health and Human Services coordinate and exchange information between state and local public health leadership specifically addressing the public health impact of PFAS within Michigan communities elevate and address locally identified issues, concerns, and requests for assistance; ensure ongoing two-way communication within communities regarding state and federal agency activities; coordinate data sharing; and identify and jointly develop action plans related to community engagement, testing, remediation, and more, for PFAS contamination sites PFAS technical team Research and review known technical information Help provide answers to pressing health and scientific questions Identify and recommend courses of action Funding State legislature provided $23.2 million of one-time funding (includes $14.8 million for DEQ and $8.4 million for DEQ) Funding will support response activities, including residential well testing, surface water sampling, fish collection & testing, filters, and continual investigation New lab equipment will also be purchased 15 FTEs will be supported by the funds (8 DHHS and 7 DEQ) Discussions regarding ongoing future funding strategies are underway
