SacPEMA February General Meeting - Tuesday, February 26, 2019

Synopsis:  New ITRC TPH Risk Assessment Guidance

Complete remediation at petroleum release sites is often infeasible for technical or cost reasons. Many of these sites may be depleted in typical petroleum compounds, such as BTEX, but still heavily contaminated in terms of Total Petroleum Hydrocarbons (TPH).

The traditional single-compound approach of managing petroleum contaminants does not fully identify short- and long-term potential environmental concerns, creates delays and cost run-ups due to residual petroleum contamination encountered during subsurface utility work or redevelopment. States should utilize a risk-based approach to more effectively incorporate TPH data in addition to traditional BTEX data in cleanup and long-term management decisions.

This ITRC comprehensive guidance on making scientific, risk-based decisions at petroleum-contaminated sites will help states develop guidance to address this common class of contaminants. It should provide the user with a greater understanding of TPH, information needed in investigating sites, and evaluating risk and establishing cleanup requirements at TPH contaminated sites. Much of the information required has been published over the past 20 years (TPH carbon range chemistry and toxicity, models and approaches to develop screening levels for direct exposure, vapor intrusion, drinking water and aquatic toxicity, gross contamination, etc.). The ITRC document is a compilation of this existing information presented in an easy-to-use manner for regulators and consultants.

The presentation will provide an overview of the process used to develop the TPH guidance as well as provide an overview of the topics in the guidance.
