Relating to the carcinogenic risk level used in the development of certain environmental remediation benchmarks.

HB 2445 requires the Texas Commission on Environmental Quality to set carcinogenic risk levels for environmental cleanup standards at no greater than 1 in 1 million (meaning one additional cancer case per million people exposed). This directly affects environmental remediation projects across Texas, including those under the Texas Risk Reduction Program, by establishing a stricter safety threshold for cleanup standards. The bill mandates that all protective concentration levels, risk-based exposure limits, and remediation benchmarks under Chapter 361 of the Health and Safety Code must adhere to this 1-in-1-million standard. The commission must update relevant rules by September 1, 2025, to implement this change.
