Relating to the liability of owners or operators of certain sources or facilities for unauthorized emissions caused by the criminal act of another.

HB 4815 modifies Texas Health and Safety Code Section 382.085 to exempt owners or operators of certain industrial facilities from liability for air contaminant emissions caused by a criminal act committed by someone else (not the facility owner/operator). This applies specifically to facilities classified under a designated Standard Industrial Classification Code. The exemption only covers emissions occurring on or after the bill's effective date (September 1, 2025, unless passed with a two-thirds vote), and does not affect liability for emissions caused by the facility owner/operator themselves. The law does not change liability for water pollution under the Water Code.
