U.S. EPA develops 6PPD-q water testing method for widespread use
On the heels of its November 2023 commitment to gather information on the common tire additive 6PPD - and its chemical by-product 6PPD-quinone – that could be used to inform a subsequent regulatory action, the U.S. Environmental Protection Agency announced today the publication of a draft testing method (EPA Method 1634) that will enable government agencies, Tribes, and other groups to determine where and when 6PPD-quinone is present in local stormwater and surface waters. The 6PPD-quinone draft method is now available at https://www.epa.gov/cwa-methods. “We heard from the Tribes and other governmental agencies that one of the highest priorities for the agency should be the rapid development of a test for 6PPD-quinone,” said Casey Sixkiller, Regional Administrator of the agency’s Region 10 office in Seattle.
