Public utilities; requiring governing bodies of public utilities to create plan for certain compliance; modifying damages in the Governmental Tort Claims Act. Effective date.

SB 650 requires municipal and publicly owned sewage utilities to create detailed five-year plans covering sewer system maintenance, overflow response, and funding. These plans must include mapping, inspection schedules for blockages, FOG (fats/oils/grease) ordinances, backflow prevention requirements, and capital improvement strategies. The bill also amends Oklahoma's Tort Claims Act to prevent personal injury claims from sewer overflows if utilities follow their approved plans, while still allowing property damage claims. This directly affects municipal sewage utilities and indirectly impacts ratepayers through potential rate adjustments. The law provides a 5-year implementation window for utilities to adopt these plans.
