“EPA’s National Priority Chemicals Trends Report evaluates and analyzes 23 of the 31 Priority Chemicals (PCs) found in industrial wastes in the United States. PCs are chemicals that are persistent, highly toxic, and can accumulate in living organisms. The Trends Report is also a multi-purpose tool used for: tracking progress toward achieving EPA’s Government Performance Results Act (GPRA) national goal to reduce PCs in waste, and identifying opportunities to reduce these PCs in concert with the objectives of the Resource Conservation Challenge (RCC), including assisting EPA in identifying potential partners for the National Partnership for Environmental Priorities (NPEP).”
