    How You Will Benefit

    The USEPA has endorsed the use of risk-based decision-making in underground storage tank (UST) corrective action programs. The course will provide you with an understanding of the differences between RBCA and the traditional corrective action process. The course identifies the role of risk assessment and fate and transport in the RBCA process and emphasizes the importance of exposure assessment. The course describes the concepts of the RBCA process and provides an understanding of the development of the target levels (cleanup levels).


    Who Should Attend

    • Environmental engineers
    • Underground storage tank owners and removal contractors
    • City and county managers
    • Attorneys and insurance underwriters
    • Petroleum marketers
    • Petroleum production and storage facilities personnel


    Topics Include

    • Step-by-step overview of the RBCA process
    • Detailed description of the risk assessment component of the RBCA process
    • Detailed description of fate and transport component of the RBCA process
    • Review of the relationship between site assessment, risk assessment, and corrective action activities within the RBCA framework
    • Case study reviews

    About the Instructors

    This course will be taught by a highly qualified instructor who is a member of ASTM Committee E50 on Environmental Assessment.


    About ASTM and Sponsoring Committee E50

    Recognizing the need for an authoritative risk-based corrective action standard, ASTM pulled together a multifunctional and multidisciplinary collection of professionals. These members of ASTM Committee E50 on Environmental Assessment and its Subcommittee E50.01 on Storage Tanks developed the standard upon which this course is based.
