Risk-based correction action

Site assessment activities are focused on collecting only tliat iiifomiatioii that is necessary to make risk-based corrective action decisions... 

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. 

Petroleum hydrocarbons are commonly found in environmental contaminants, although they are not usually classified as hazardous waste. However, soil and groundwater contamination by petroleum hydrocarbon has spurred various analytical and site remediation developments (e.g., risk-based corrective actions).

Risk Based Corrective Action Process Flow Chart... 

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).
