The Coast Guard must approve marine foam fire-extinguishing systems. Currently, eight guidance documents set out the existing type approval criteria. The Coast Guard proposes to update and codify the type approval criteria to reflect current industry practices. Criteria updates would reflect advancements in technology, reduce certain testing and design requirements, and reduce the administrative burden on industry and the government. This deregulatory measure would result in cost savings for industry and the government. Comments and related material must be received by the Coast Guard on or before 27 July 2026. POC is John Miller, Coast Guard; telephone 571-608-3413, email John.H.Miller@uscg.mil. (Federal Register 26 May 2026 [Proposed Rule] Pages: 30557-30595)
