General Information
Action Summary This final exempt action amends 9VAC25-31-200 by adding a new subsection F which requires PFAS monitoring by certain industrial users discharging to a POTW. This is a substantive new requirement for POTWs and specifies that they: • Require quarterly discharge monitoring for PFAS by certain categories of existing and new industrial users for an initial characterization period of one year. These include: o Any facility manufacturing PFAS, any electroplating or metal finishing facility using PFAS, any semiconductor or circuit board facility using PFAS, any paper or packaging manufacturing facility using PFAS, and any textile mill, tannery, or leather, fabric, or carpet treater using PFAS; o Centralized waste treatment industrial facilities; o Industrial launderers defined by NAICS (North American Industry Classification System) 812332; and o An airport, air base, air station, fire training facility, landfill, or other facility or site that the publicly owned treatment works has a reasonable basis to believe is a source of PFAS. • May discontinue quarterly discharge monitoring for PFAS by an industrial user with proper monitoring results that are below the method detection level for the first two quarters; • Require industrial users to continue discharge monitoring where PFAS is detected in quantities above the method detection limit; • Require any new industrial user within the categories above to monitor their discharge for PFAS beginning within 90 days of the commencement of discharges to the POTW; and • Report monitoring results to the Department of Environmental Quality on a quarterly basis. The amendments also specify industrial users are required to report monitoring results for PFAS to the POTW no later than 30 days after receipt from the laboratory and the U.S. Environmental Protection Agency Method 1633 is the applicable test method.
