Risk-Based Corrective Action RBCA

Risk-based decision making and risk-based corrective action arc decision making processes for assessing and responding to a health hazard. The processes take into account effects on human healdi and the enviroiunent, inasmuch as chemical releases vaiy greatly in terms of complexity, physical and chemical characteristics, and in the risk that they may pose. Risk-based corrective action (RBCA) was initially designed by the American Society for Testing and Materials (ASTM) to assess petroleum releases, but tlie process may be tailored for use with any hazard.

Using the fraction method, hydrocarbon fractions are established on the basis of compounds having similar leaching and volatilization factors. The TPHCWG (1997b) used equations from the Standard Guide for Risk-Based Corrective Action (RBCA) Applied to Petroleum Release Sites (ASTM 1995) to estimate the volatilization factor and leaching factor. These equations are shown below. 

ASTM s risk-based corrective action (RBCA) uses a tiered approach to data collection and analysis in supporting decisions on site assessment and response to petroleum. The RBCA procedure begins with the assessment of the site (see Figure 5-2 for RBCA process flow-chart). 

Concentration-based cleanup goals are being replaced with performance-based goals, providing an opportunity to prioritize sites for maximum risk reduction to the public and the environment. Risk-based corrective action (RBCA pronounced rebecca ) is defined by the EPA as an approach to corrective action that integrates components of traditional corrective action with...
