Concerned with the possibility of further delays, at least seven states have developed policies or are pursuing policies with standards stricter than EPA’s current health advisory of 70 parts per trillion (ppt) for PFOA and PFOS. EPA initiated the steps to evaluate the need for an MCL for PFOA and PFOS under the regulatory determination process. “California is on the verge of setting a precedent for chemical-control policy in the US. Generally, the ANR is responsible for identifying when a new standard or revision to a federal standard … For EPA, the MCL development process involves a team of scientists, toxicologists and other experts who study a chemical before first setting a maximum contaminant level goal (MCLG). The chart below illustrates the discrepancies between the regulatory levels for PFOA and/or PFOS. And while California has not yet released an MCL for any specific PFAS, the state recently lowered its response levels from 70 ppt to 10 ppt for PFOA and 40 ppt for PFOS. Perfluorooctanoic Acid (PFOA) 8. Perfluorohexane Sulfonic Acid (PFHxS) 51. ” An update from U.S. EPA on its current position regarding these potential regulatory actions is expected soon.

PFOA (Proposed MCL – various penalties, possible Clean Up) Pending (NHDES Final Rulemaking Proposal). 335-67-1. Perhaps as important as its decision to promulgate primary drinking water standards for PFOA and PFOS, in Regulatory Determination 4, USEPA also expressed its intention to move forward with its consideration of other PFAS compounds on an accelerated basis. Perfluorooctane Sulfonic Acid (PFOS) 16. California must immediately ban the use of all fire-fighting foams containing PFAS. For more information on PFAS chemicals, and the regulatory and litigation risks that they pose, please visit our PFAS webpage. Proposed PFAS MCLs; Contaminant. As PFAS in excess of the response levels is found in water supply wells, the water treatment facility will either have to notify customers, provide treatment or possibly shut down the affected source. Under the regulations, the MCL is considered violated when three months of sampling results exceed the 20 ppt level or if PFAS levels from one or two months are high enough to identify a violation regardless of subsequent monthly results. Last week, the California Environmental Protection Agency’s Water Resources Control Board made two major announcements regarding PFAS: California will not yet initiate steps to promulgate Maximum Contaminant Levels (MCL) for PFOA and PFOS in the state’s drinking water. Once OEHHA develops a public health goal, the State Board may rely on it as the foundation for an 375-95-1. There are many other PFAS, including GenX chemicals and PFBS in use throughout our economy. PFAS: in California, regulators put cleanup levels on hold, but announce major data hunt. California must establish mandatory response levels (maximum contaminant levels – MCL’s) of 1 part per trillion, (ppt.) MCL (ng/L) Chemical Abstract Services Registry Number (CASRN) Perfluorononanoic Acid (PFNA) 6. The most immediate impact of the new MCLs will be the testing obligation it imposes on drinking water providers. Last month, the California State Water Resources Control Board (State Board) hosted a comprehensive two-day seminar on per- and polyflouroaklyl substances (PFAS) in California. Today’s Agenda Time Topic Presenter 10:00 – 10:15 Welcome, introductions, and summary of MCL development stakeholder engagement process Stephanie Cooper, Deputy Commissioner for Policy 10:15 – 10:30 PFAS Updates, including: PFAS … Provide the opportunity for the public to comment on and contribute to the information the EPA may consider related to the regulation of PFAS in drinking water. However, EPA has issued a health advisory for PFOA and PFOS. We coordinate a large and diverse coalition of advocates, policymakers, scientists, and representatives from the most impacted communities to influence public policy, corporate practices, and end-of-life management decisions on products containing these deadly chemicals. PFAS Drinking Water Standard (MCL) Development Stakeholder Group Meeting Thursday, April 11, 2019 (10:00-12:30) MassDEP, One Winter Street, Boston, MA . 13 ppt. The sum of these five PFAS … The molecules in question are per- and polyfluoroalkyl substances (PFAS). Conclusion. Safer States is at the forefront of a state-driven national movement to combat exposures to PFAS chemicals. In response to PFAS concerns, California has considered a PFAS limit in drinking water at 0.5 parts per billion. PFOS (Notification) Approved (Regulation) New Jersey. The MCL is 20 nanograms per liter (ng/L) and it is for five PFAS in drinking water: PFOA (perfluorooctanoic acid), PFOS (perfluorooctane sulfonic acid), PFHxS (perfluorohexane sulfonic acid), PFHpA (perfluoroheptanoic acid), PFNA (perfluorononanoic acid). PFOA and PFOS are the most studied PFAS chemicals and have been voluntarily phased out by industry, though they are still persistent in the environment. Investigating PFAS in California, like much of the rest of the country, ... it is “committed to following the Safe Drinking Water Act process for evaluating drinking water standards for PFAS, including an MCL for PFOA and PFOS. For example, for PFAS substances in drinking water, the smallest concentration is 5.1 ppt (California; PFOA only) and one of the largest values is 140,000 ppt (Michigan; PFHxA only). in groundwater and drinking water for all PFAS varieties combined. The regulatory process to establish a MCL under the federal Safe Water Drinking Act typically takes years. This is based on a toxicological review and critical effects determination of exposure by the Office of Environmental Health Hazard Assessment (OEHHA). Probably will change the current 70 ppt standard. The Agency will not pursue a treatment standard at this time.
