Technological Hazards metrics used in the PRISM approach and the methods used to collect and assess.

Technological Hazard Type Spatial Extent Exposure Calculation
Nuclear Facilities All nuclear reactors and storage facilities in US identified and given a 10-mile buffer. Proportion of each land-use classification used to estimate exposure extent.
Superfund Sites Superfund sites - proposed or active in the US identified and given a 5-mile buffer. Proportion of each land-use classification used to estimate exposure extent.
Toxic Release Inventory (TRI) Sites TRI facilities identified when threshold chemical release criteria are met and given a ¼-mile buffer. Proportion of each land-use classification used to estimate exposure extent.
Resource Conservation and Recovery (RCRA) Sites All RCRA Site (LQGs, TSDs, and TRANSs) point data from EPA FRS Geodatabase are given a ¼-mmile buffer. Proportion of each land-use classification used to estimate exposure extent.
