Parameter Estimation Guidelines for Risk-Based Corrective Action (RBCA) Modeling

TRRP Training: 2022 Program

presented by: GSI Environmetal Inc.

Texas Risk Reduction Program regulations (TRRP; 30 TAC 350) establish consistent risk-based protocols for assessment and response to soil, groundwater, or surface water impacts associated with environmental releases of regulated wastes or substances.

Presented by GSI Environmental Inc., this popular and informative training series is a must for professionals who need a working understanding of TRRP and those needing to stay up-to-date with the latest TCEQ TRRP guidance and policies.

TRRP Training Course (2 Days): Provides an overview of the TRRP framework and step-by-step training on property assessment and response action procedures established under the TRRP rule

Attendees will become acquainted with rules, key guidance and policies covering affected property assessments, protective concentration levels, and response actions. The course material presents strategies for efficient project management in compliance with TRRP and explains the various report forms adopted by TCEQ.

Abstract

Download Paper

For use in risk-based corrective action (RBCA) analyses, simple analytical fate-and-transport models can provide a cost-effective means of estimating exposure concentrations and developing risk-based soil and groundwater remediation standards. Under ASTM E-1739 “Standard Guide for Risk-Based Corrective Action Applied at Petroleum Release Sites,” such models are recommended as a conservative first step under Tiers 1 and 2 of the site evaluation process, prior to use of more complex numerical modeling methods under Tier 3. However, the reliability of an analytical model as a conservative predictor of chronic exposure levels depends upon proper characterization of key physical and chemical parameters.
This paper reviews a system of analytical fate-and-transport models compiled expressly for use with the ASTM RBCA Standard and provides practical guidelines for measurement and/or estimation of key input parameters for each model. Contaminant transport pathways addressed in this paper include soil-to-air volatilization, soil-to-groundwater leaching, lateral air transport, and lateral groundwater transport. Parameter selection guidelines discussed in this paper relate specifically to the analytical expressions listed in Appendix X.2 of ASTM E-1739. However, these guidelines are generally applicable to a broad range of soil, air, and groundwater transport models.
