Water and water rights; establishing procedures for permitting, monitoring, and reporting of groundwater use. Effective date.
SB 259 requires groundwater permit holders to submit annual usage reports, with specific additions for swine operations using liquid waste systems that must indicate if they are licensed under Oklahoma's Concentrated Animal Feeding Operations Act. It updates waste prevention rules to prohibit inefficient use, pollution, and unauthorized drilling, while expanding the Oklahoma Water Resources Board's authority to investigate complaints, implement metering schedules, and enforce penalties. The bill directs the Board to monitor groundwater use, notify agriculture officials about unlicensed operations, and require landowner notice before inspections. An appropriation funds the Board's new monitoring and enforcement responsibilities under this legislation.

This bill was revised to move from the House version to the Senate floor version, incorporating specific amendments to Oklahoma water laws. The changes focus on clarifying reporting requirements for animal feeding operations, defining waste prevention measures for groundwater, and establishing a formal process for investigating and penalizing water waste.
Scope change
The bill's scope remains focused on groundwater regulation, but the applicability of reporting rules was expanded to include specific details for swine operations, and enforcement jurisdiction for pollution complaints was clarified.
REQUIREMENT
Updated reporting rules to require swine animal feeding operations using liquid waste systems to explicitly state their licensing status on annual water reports.
Clarified that nonuse or conservation practices will not reduce a permit holder's future water allocation share.
ENFORCEMENT
Expanded the Board's authority to investigate complaints and take action against water waste, including seeking court injunctions and imposing fines.
Shifted jurisdiction for pollution-related waste complaints from the Water Resources Board to the Department of Environmental Quality or other appropriate agencies.
