Michigan, Minnesota investing in initiatives to address pfas contamination

water: 11 ppt for PFOS and 420 ppt for PFOA, according to the American Water Works Association. In 2018, Michigan began testing public water systems as part of a systematic, ongoing statewide effort to identify sources of contamination through an inter-agency Michigan PFAS Action Response Team. The team was created by executive order in November 2017 by then-Gov. Rick Snyder; Gov. Gretchen Whitmer used an executive order in February 2019 to make it a permanent body within the Michigan Department of Environment, Great Lakes, and Energy. (Two pending bills, HB 4746 and SB 402, would codify the action team in state law.) Among this team’s tasks: • Identify impacted locations and implement a plan to assist state and local authorities to ensure the safety of Michigan’s land, air and water. • Assess the status of PFAS- contaminated sites and develop individualized site-response strategies. • Develop environmental response and health protocols. In 2019, Michigan officials

Wolverine will pay $69.5 million to extend municipal water to more than 1,000 properties, to continue the use of drinking water filters in the area where PFOA and PFOS concentrations exceed 10 ppt, and to sample residential wells. In addition, Wolverine will have to monitor contamination, as well as investigate and address PFAS contamination in surface waters. In January, Michigan Attorney General Dana Nessel sued 17 companies, alleging they “deliberately concealed the dangers of PFAS and withheld scientific evidence” about them while selling and distributing them in Michigan “in a way that they knew would contaminate natural resources and expose Michigan residents to harm.” Michigan Sen. Winnie Brinks, whose constituents were
in the damaged areas. An August 2019 report from the Minnesota Pollution Control Agency and the Department of Natural Resources (co-trustees of the settlement fund) said $32.4 million is estimated to be spent in the current fiscal year on PFAS cleanup projects. If any funds are left over after those goals are met, money could be used for other projects around the state, says Walker Smith, a spokesman for the Pollution Control Agency. Last year, Minnesota also lowered its own PFOS health advisory level —which was already lower than the EPA’s 70 ppt — from 27 to 15 ppt. Legislation introduced in February (HF 3268) would create a PFAS task force akin to Michigan’s, with a goal of reducing contamination by 50 percent by 2026 and 90 percent by 2030. NEW RULES ON DRINKINGWATER AND USE OF FIREFIGHTING FOAMS Other Midwestern states are also taking regulatory and legislative action, especially to ban firefighting foams made with PFAS: Minnesota andWisconsin have prohibitions in place; legislation was introduced this year Iowa (HF 2241) and Ohio (HB 328). InWisconsin, the state Department of Natural Resources has begun the rule-making process to set maximum contaminant levels for drinking water; the new rules are anticipated to be finalized in late 2021 or early 2022, and take effect later that year. The Illinois Environmental Protection Agency is proposing new, enforceable groundwater standards for PFAS and will send them to the state’s Pollution Control Board for approval later this year.

announced they would begin the rule-making process to formalize new maximum contaminant levels for seven specific PFAS compounds based on recommendations from the action team’s Science AdvisoryWorkgroup. The state has spent about
Along with this activity in state agencies, legislation to set maximum contamination levels for PFAS has been introduced this year in Illinois (HB 3982), Indiana (HB 1338), Iowa (HF 2343) and Ohio (HB 497). Iowa and Ohio also have released PFAS action plans laying out the need to identify sites that are or might be contaminated, steps to prevent contamination, and steps to educate the public and local officials. According to Klaper, identifying and eliminating sources of PFAS contamination are good steps to take, but their known and suspected health problems won’t go away, especially since the science is known only for a handful of the thousands of PFAS compounds. “It may be that we have to get rid of the whole class of chemicals” as was done with PCBs and CFCs, she says.
move, but it started a good conversation,”Brinks says, adding she is glad the state is moving to regulate the seven compounds. “These seven are simply the ones we know the most about, so that’s where we’re starting.” Minnesota and Ohio, too, have turned to the courts. Ohio sued DuPont in 2018; that case is winding its way through a state court. Minnesota’s 2010 lawsuit against 3M alleged the company’s production of PFAS had damaged drinking water and natural resources in the southeast Twin Cities metro area. 3M settled in February 2018 for $850 million; as a result, the state has $720 million to use for safe drinking water and natural resources enhancement projects

$25 million annually on PFAS cleanup since creation of the Action Response Team, says department spokesman Scott Dean. Legislators appropriated $30.6 million for PFAS activities in fiscal year 2019. Michigan is also suing PFAS manufacturers as part of what Dean says is a “multi-faceted” approach to the cleanup problem. In February, the state settled a two-year-old lawsuit against WolverineWorldwide Inc. over PFAS contamination of residential wells in townships north of Grand Rapids. Under a proposed consent decree,
U.S. and Canadian environmental agencies preparing to tighten federal regulation of PFAS
PFAS have been on the U.S. Environmental Protection Agency’s radar since at least 2002, when it issued “significant new use rules” requiring that the EPA be notified before any imports or manufacturing of 88 such compounds. The agency’s 2019 PFAS Action Plan indicates a more active regulatory regime is coming, including national maximum contaminant levels, nationwide monitoring of drinking water, and the addition of some PFAS chemicals to the EPA’s Toxics Release Inventory Program (which tracks the management and releases of more than 650 chemicals that pose threats to human health and the environment). Pending legislation in the U.S. Congress (H.R. 535) would designate PFAS as hazardous substances and require remediation of their release into the environment; require the EPA to create drinking water regulations for certain PFAS compounds and to test all PFAS compounds for
the EPA to classify PFAS chemical compounds as hazardous substances and would hold polluters accountable for the cleanup of their contamination under an existing Superfund law. In Canada, PFOS and PFOA compounds are controlled under federal “Prohibition of Certain Toxic Substances Regulations,” which prohibit the manufacture, use, sale, offer for sale or import of these substances, as well as products containing them, with a limited number of exemptions. Health Canada posted finalized “Guidelines for Canadian Drinking Water Quality for PFOS and PFOA ” in December 2018, as well as updated guides for “maximum acceptable concentration” levels in April 2019. Environment and Climate Change Canada (the EPA’s Canadian counterpart) is in the process of amending the 2012 regulations by removing the exemptions. The proposed amendments are scheduled for publication in fall 2020, followed by a 75-day public comment period.
