Bill No. 3, introduced by Senators Green and Hamilton and Representative George, establishes new regulations regarding the land application of sludge and biosolid materials in Oklahoma. Effective July 1, 2027, the bill prohibits the land application of these materials and mandates that the Department of Environmental Quality (DEQ) will not issue new permits for such applications. Existing permit holders are required to reduce their land application of sludge and biosolid materials by 25% by September 1, 2025, and by 50% by September 1, 2026. Additionally, permit holders must submit a plan for the complete cessation of land application activities to the DEQ by September 1, 2025.

The bill also defines "biosolid material" as sewage sludge containing perfluoroalkyl and polyfluoroalkyl substances and refers to the existing definition of "sludge" as per Oklahoma Statutes. The DEQ is tasked with promulgating rules to implement these provisions. An emergency clause is included, allowing the act to take effect immediately upon passage and approval, emphasizing the urgency of the public health and safety concerns addressed by the legislation.
