Water and water rights; establishing procedures for permitting, monitoring, and reporting of groundwater use. Effective date.
SB259 revises Oklahoma’s groundwater permitting and enforcement framework. It requires permit holders to continue filing annual water-use reports and adds specific reporting for groundwater used at certain swine animal feeding operations, including whether the operation is licensed under the Oklahoma Concentrated Animal Feeding Operations Act. The bill also directs the Oklahoma Water Resources Board (OWRB) to notify the Department of Agriculture, Food, and Forestry when it identifies unlicensed operations meeting those criteria.
The bill expands the definition of prohibited groundwater waste and strengthens enforcement. It adds a new restriction on groundwater use for cooling at data processing facilities and data centers unless the applicant uses low-consumptive, recirculating cooling technologies such as closed-loop or dielectric immersion systems. It also requires complaints of waste to be filed with the OWRB and, where applicable, local groundwater irrigation districts, and authorizes investigations, cease-and-desist actions, fines, penalties, permit suspension, and court enforcement. Waste by pollution remains primarily within the jurisdiction of environmental agencies rather than the OWRB.
SB259 also requires the OWRB to adopt rules and policies to improve administration of groundwater reporting and enforcement. Those rules must support timely review of reports, modernize data collection, create an online or electronic reporting system, investigate waste claims, and impose fines and penalties for overuse or waste. The bill updates statutory language and references and is set to take effect November 1, 2026.
The overall sentiment appears generally supportive, with strong final passage in both chambers and committee approvals, though not unanimously. The bill passed the House overwhelmingly on third reading and cleared the Senate with a solid majority, suggesting broad agreement on tightening groundwater oversight and improving reporting systems. However, the narrower committee vote in the House Energy and Natural Resources Oversight Committee and the Senate floor opposition indicate some concern about the scope of regulation and enforcement changes.
The main points of contention appear to be the bill’s expanded regulatory reach and enforcement tools. Potentially sensitive issues include the new reporting obligations for swine feeding operations, the notification of unlicensed operations to agriculture officials, and the new limits on groundwater use by data centers and similar facilities. Opponents may also have concerns about increased compliance costs, administrative burden, and the OWRB’s expanded authority to investigate, fine, and suspend permits.
SB259 amends 82 O.S. 2021 Sections 1020.12 and 1020.15 and creates a new codified section, 1020.19B, to expand the Oklahoma Water Resources Board’s authority over groundwater reporting, monitoring, and enforcement. It adds specific reporting requirements for certain animal feeding operations, authorizes broader complaint investigation and enforcement procedures, and requires the Board to modernize its reporting systems and adopt electronic data collection. The bill also creates a new permitting limitation for groundwater use in data center cooling, affecting applicants that rely on evaporative or other consumptive cooling methods.
The bill appears to have broad legislative support overall, reflected in strong floor votes in both chambers and committee approvals. At the same time, the presence of some no votes and a closer committee margin in one House oversight committee suggest that while many lawmakers favored stronger groundwater oversight, there was not complete consensus on the bill’s regulatory expansion and enforcement provisions.
The most notable disagreements likely center on the bill’s increased oversight of groundwater users and the practical burden of compliance. The reporting and notification requirements for swine animal feeding operations may be viewed as an added regulatory layer for agricultural operators, while the new restrictions on data center cooling could be seen as limiting development or increasing infrastructure costs for technology and industrial users. There may also be concern about giving the OWRB broader enforcement powers, including fines, penalties, cease-and-desist actions, and permit suspension, as well as the requirement to modernize systems and process complaints more aggressively.
