What is the Texas Risk Reduction Program (“TRRP”)?

The TRRP is TCEQ’s “cleanup cookbook” for Texas remediation projects. The detailed TRRP regulations, and extensive accompanying guidance issued by TCEQ, provide a comprehensive risk-based approach for assessing and responding to environmental contamination. TRRP requires persons addressing environmental contamination to perform a series of activities with respect to a site. Those activities include:

  • Conducting an affected property assessment, classifying groundwater, determining land use, and notifying affected offsite property owners;
  • Determining critical protective concentration levels for the affected environmental media (e.g., soil, groundwater, surface water) and potential exposure pathways (e.g. dermal exposure to soil, human ingestion of groundwater, ecological receptors);
  • Preparing an Affected Property Assessment Report (“APAR”) which sets out in detail the information noted above, along with a significant amount of other site-related information called for by TRRP;
  • Developing a Response Action Plan (“RAP”) that describes how the proposed response objectives will be met; and
  • Preparing and submitting to TCEQ following completion of response actions, a Response Action Completion Report (“RACR”).
