Risk Analysis to Support Potential Revisions to Underground Storage Tank (UST) Regulations
The U.S. Environmental Protection Agency (EPA) is evaluating costs and benefits associated with proposed regulations that are intended to prevent or decrease the severity of gasoline releases from underground storage tank (UST) systems. These regulations may, for example, include increased operation and maintenance and improved leak detection. This report supports EPA’s cost/benefit analysis (part of the overall regulatory impact analysis) with information on benefits to human health that may result from the proposed regulations.
The primary objective of the risk assessment is to support EPA’s regulatory cost/benefit analysis. The assessment provides results for national-scale conditions and a range of possible release scenarios (e.g., different release volumes); these results enable EPA to evaluate potential health benefits for a wide variety of regulatory benefit scenarios.
