U.S. EPA’s Interim Guidance on PFAS Destruction and Disposal lacks adequate precision
News
21 Jan 2021 | JDSupra
Following the guidance’s recommendations is not a "get-out-of-jail-free" card; improper disposal or incomplete destruction of PFAS that may occur, even if following the guidance, does not protect a company from a government enforcement action or an action for damages under, for example, federal or state statutes, or common law.
