Environmentalists and the chemical sector are sparring over whether EPA should endorse interim storage for per- and polyfluoroalkyl substances (PFAS) as part of its interim guidance on PFAS disposal, with environmentalists warning of major data gaps about disposal but industry claiming that "safe and effective" disposal methods exist.

At the time, it said it would incorporate comments into a revised document.
