HB 2445 amends the Health and Safety Code to establish a minimum carcinogenic risk level for environmental remediation benchmarks. It mandates that the Texas Commission on Environmental Quality (TCEQ) set the carcinogenic risk level at a rate no greater than one in one million when developing protective concentration levels, risk-based exposure limits, or other remediation standards. The bill specifically applies to programs such as the Texas Risk Reduction Program and similar initiatives regulating environmental contamination cleanup​.
