Robbie Ettinger, Simone Smith, and Olga Stewart joined the new Total Petroleum Hydrocarbons (TPH) Risk Evaluation Committee formed by the Interstate Technology & Regulatory Council (ITRC).

The Committee will review, update, develop guidance methods and procedures for evaluating risk, and establish cleanup requirements at TPH contaminated sites. A comprehensive state guidance document based on making scientific, risk-based decisions at petroleum-contaminated sites will be developed by the team.

The ITRC document will primarily be a compilation of the existing information presented in an easy-to-use manner for regulators and consultants. The existing information was published by states and other entities over the past 20 years. The guidance included TPH carbon range chemistry and toxicity, methods to develop weighted toxicity factors and screening levels for different fuel types, models and approaches to develop screening levels for direct exposure, vapor intrusion, drinking water and aquatic toxicity, and gross contamination. The new document will incorporate updated TPH information currently being collected by the American Petroleum Institute (API).
