National Hazards Vulnerability and the Remediation, Restoration and Revitalization of Contaminated Sites-2. RCRA Sites.

Natural hazards can be powerful mechanisms that impact the restoration of Resource Conservation and Recovery Act (RCRA) contaminated sites and the community revitalization associated with these sites. Release of hazardous materials following a natural hazard can impact communities associated with these sites by causing the release of hazardous or toxic materials. These releases can inhibit the restoration of the sites, thus altering the long-term sustainable community revitalization. Hazard-related contaminant releases in areas characterized by large populations can create problems equal to those posed by the original site clean-up. Similarly, natural hazards can enhance the probability of future issues associated with the renovated sites. This manuscript addresses the co-occurrence of 12 natural hazards (singly and in combination) at individual RCRA sites. The co-occurrence was determined by the co-location of exposure likelihoods determined from the Cumulative Resilience Screening Index (CRSI) and the site locations for RCRA facilities provided by Environmental Protection Agency. Results showed that several natural hazards were likely to occur at RCRA facilities and these occurrences should be included in management and policy evaluations of these sites.
