The bill amends 59 O.S. 2021, Section 1158, which governs the installation of individual sewage disposal systems in Oklahoma. It reduces the threshold for certification from installing more than ten systems per year to just one system per year. This change means that any individual intending to install even a single sewage disposal system must now obtain certification from the Department of Environmental Quality. Additionally, the bill updates the terminology used in the statute, changing "systems" to "system" and "Specialists" to "specialists."

Furthermore, the bill outlines the responsibilities of the Environmental Quality Board, which is tasked with establishing minimum certification requirements, procedures for penalties, and rules for the suspension or revocation of certifications. It also mandates that an annual fee be paid for each certification. The bill allows the Department of Environmental Quality to impose administrative penalties for violations and outlines the process for hearings related to certification issues. The act is set to take effect on November 1, 2025.
