TRI DATA FOR SITES IN PA, MD, DE, DC, VA, AND WV

Description:
The Environmental Monitoring and Assessment Program (EMAP) is planning in conjunction with EPA Region III a comprehensive multiple resource assessment in the Mid-Atlantic region--the land area and near coastal waters associated with all of PA, WV, MD, DE, VA, and parts of NJ, NY, and NC. Components of the Mid-Atlantic Integrated Assessment (MAIA) Project will be: (1) a research dimension that develops and tests crossresource indicators of ecological condition and stress; (2) a monitoring dimension that seeks to characterize the condition of ecological resources--forests, agroecosystems, streams, estuaries, landscapes; and (3) an assessment dimension that involves diagnostic analysis of associations between condition and stressors. Results will result in enhancements to the EMAP design and approach and will provide insight into the efficacy of ecosystem and watershed management approaches to addressing resource and environmental protection concerns at different spatial scales. This data layer includes point locations for Toxic Chemical Release Inventory (TRI) data from the Environmental Protection Agencys Toxic Release Inventory System (TRIS) for all States in EPA Region 3 (PA, MD, DE, DC, VA, WV) for the years 1987-1990. This data layer includes yearly information by State about the facilities that report releases and the types of chemicals being released. TRI includes information from facilities on the amounts of over 300 listed toxic chemicals that the facilities release directly to air, water, or land or that are transported (transferred) off-site.
