Why is EPA interested in tracking inert materials in a P2 audit? Are inert materials covered under the PFPR regulation?
Inert materials are covered in discharges from PFPR operations if they are also priority pollutants. However, the reason EPA suggests tracking inert materials during the P2 audit is to identify possible contaminants in wastewater that will require treatment prior to discharge or to identify characteristics that may hinder effective treatment of pesticide active ingredients or priority pollutants.
