Texas Cleanup Program

The TCEQ oversees the investigation and cleanup of hazardous and nonhazardous pollutants released into the environment. Cleanup is conducted using a risk-based approach outlined in the Texas Risk Reduction Program (TRRP) rule (30 TAC Chapter 350). Major components of the rule include the requirements for assessment, exposure pathways evaluation, development of protective concentration levels (PCLs), property owner and public notice, remedy selection standards, and institutional controls. This page discusses cleanup value differences.
