    Guidance Leaflet: PFOA in Fire-Fighting Foams

    This guidance document from Ireland's Environmental Protection Agency explains the regulations around PFAS chemicals — particularly PFOA and PFOS — found in aqueous film-forming foam (AFFF) used in fire suppression systems and extinguishers. It outlines a phased timeline of restrictions, culminating in a full ban on AFFF containing PFOA by July 4, 2025, and details the steps organizations must take to check their systems, notify the EPA, and properly dispose of non-compliant foams. Businesses holding more than 50 kg of such foam at any location are required to report their stockpiles annually to the EPA via its EDEN portal.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
