Course Summary:

This manual presents a risk-based approach for the management of hydrocarbon-impacted soil at E&P sites that emphasizes the protection of human health. This risk-based approach was derived from the work of the Total Petroleum Hydrocarbon Criteria Working Group (TPHCWG) as later modified by the Petroleum Environmental Research Forum (PERF) as part of PERF Project 97-08. It generates a risk-based screening level, or RBSL, for crude oil in soil that can be used as part of a Tier 1 risk evaluation. This RBSL is expressed in terms of TPH (total petroleum hydrocarbon) in soil and represents the soil TPH concentration that is protective of human health. RBSLs are calculated using exposure equations that are recognized by the U.S. Environmental Protection Agency as providing conservative estimates (i.e., lower than necessary for the protection of human health) of acceptable hydrocarbon concentrations in soil. The manual also presents results from the application of this risk-based approach to a typical E&P site. These results confirm that the TPH concentration of 10,000 mg/kg in soil that is often proposed as a regulatory criterion for E&P sites is protective of human health.

  • Introduction
  • Risk-Based Decision Making
  • Characteristics of Crude Oils, Refined Petroleum Products, Condensates, and E&P Wastes
