The National Priority Chemicals (PCs) Trends Report is intended primarily to: (1) evaluate the progress made in achieving EPA's Government Performance Results Act (GPRA) national goal of a 10 percent reduction of PCs in wastes by 2008, compared to the 2001 quantities and (2) provide information and trends on the quantities (aggregated and non-aggregated) and management methods of the PCs contained in hazardous wastes (Resource Conservation and Recovery Act (RCRA) Subtitle C) and non-hazardous industrial wastes (RCRA Subtitle D) for the nation, EPA Regions, Stats,. Industry sectors, and federal facilities to assist in identifying potential waste minimization opportunities to reduce these chemicals. The data and trends analyses developed for the report supports this program and helps us better understand trends in the generation and management of the PCs, assess chemical reduction priorities, and identify opportunities for eliminating or reducing the PCs. The 31 PCs consist of 28 organics and 3 metal/metal compounds that are frequently found in releases to water, air, and land. These chemicals are present in soil, sediment, ground water, and surface water, air, and/or biota, with many serving as the basis for a waste being classified as hazardous. The PCs are frequently found in wastes (hazardous and non-hazardous) and likely present opportunities for PC reductions in the manufacturing, commercial, and government operations that generate these wastes.
