HB 1331 increases penalties for trespassing on or damaging critical infrastructure facilities in Oklahoma. Simple trespass becomes a misdemeanor (up to $1,000 fine or 6 months jail), while damaging facilities or intending to disrupt operations becomes a felony (up to $100,000 fine or 10 years imprisonment). The law broadly defines "critical infrastructure" to include power plants, water treatment centers, cell towers, pipelines, and other essential facilities requiring physical barriers or clear "no trespassing" signs. Organizations conspiring with offenders face fines ten times the standard penalty for the underlying violation.
