Risk Assessment--the Future Trend

MARKS, GILLIAN A., Mittlehauser Corporation, Laguna Hills, CA

Many organizations today are faced with cleaning a site or facility, selecting appropriate remedial alternatives, or explaining the potential effects on human health and the environment caused by the releases of toxic compounds into the air, soil, and water. The use of risk assessment (RA) as a management tool is increasing because it offers an integrated approach to the analysis of toxilogical, geological, physio-chemical, meteorological, statistical, and biological parameters that must be evaluated in the assessment of potential impacts to human health.

The regulatory atmosphere in the 1990s is leaning toward the adoption of further laws requiring the completion of the RA process. Any industry involved in submitting permit applications to Air Quality Management Districts or complying with California's Proposition 65 and AB 2588 will be required to prepare RAs. Several guidance documents are available that support the RA process including the California Site Mitigation Decision Tree Manual published by the State Department of Health Services (DHS), which bases its approach on developing cleanup objectives (Applied Action Levels) on RA.

This presentation focuses on the applications RA can have to the petroleum industry and the kinds of data that each case should develop to make maximum use of the RA process.
