On August 30th, EPA granted the 2007 Petition from the Pesticide Action Network North America (PANNA) and the Natural Resources Defense Council (NRDC) requesting that EPA revoke all chlorpyrifos tolerances. This followed the Ninth Circuit order earlier this year for EPA to: “(1) grant the 2007 Petition; (2) issue a final regulation within 60 days following issuance of the mandate that either (a) revokes all chlorpyrifos tolerances or (b) modifies chlorpyrifos tolerances and simultaneously certifies that, with the tolerances so modified, the EPA “has determined that there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information,” including for “infants and children”; and (3) modify or cancel related FIFRA registrations for food use in a timely fashion consistent with the requirements of 21 U.S.C. § 346a(a)(1).”

8.18.2021 EPA Finalizes Hazard Assessments for Two Fuel Additives (ETBE and tert-Butanol):

On August 18th, EPA finalized the long-awaited hazard assessments for both Ethyl Tertiary Butyl Ether (ETBE) and tert-Butyl Alcohol (tert-Butanol).  ETBE was previously added to gasoline to increase its octane levels. It is still registered with EPA for use as a fuel additive, but it is not used currently in the United States.  tert-Butanol is one of the primary metabolites of ETBE and has also been used as a fuel oxygenate. It is also used for other purposes including as a solvent and as a dehydrating agent.

In January, EPA obtained data that some mosquito control pesticides contained detectable levels of certain PFAS.  In a joint investigation with the State of Massachusetts, EPA found that fluorinated high-density polyethylene (HDPE) containers containing a mosquito control pesticide were leaching PFAS into the product. Now, EPA is testing different brands of fluorinated containers to determine whether they contain and/or leach PFAS and has asked the states with existing stocks of these pesticides to discontinue use as EPA evaluates the issue. Information on the EPA activities can be found here. EPA also began working with USDA and FDA to get a better understanding of the use of fluorinated polyethylene containers for pesticides and other products.

Care about Drinking Water Regulations?

7.22.2021 Request for Comment and Public Workshop for California Drinking Water Public Health Goals for PFOA and PFOS: The California Office of Environmental Health Hazard Assessment (OEHHA) released a draft document for public review describing proposed Public Health Goals (PHGs) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) in drinking water. A PHG is the level of a drinking water contaminant at which adverse health effects are not expected to occur from a lifetime of exposure.  PHGs published by OEHHA are considered by the State Water Resources Control Board in setting drinking water regulatory standards (Maximum Contaminant Levels, or MCLs) for California. The proposed PHG of 0.007 parts per trillion (ppt) for PFOA is based on kidney cancer in humans and the proposed PHG of 1 ppt for PFOS is based on liver and pancreatic tumors in laboratory animals. The draft technical support document can be found here. Public comments are due September 28, 2021. Details about how to send comments and a public workshop that will be held on September 28, 2021 can be found here.
