SB2141 creates the “Oklahoma PFAS-Safe Biosolids and Farmland Protection Act” to regulate the land application of human-derived biosolids and septage on agricultural land. The bill requires PFAS testing before any land application, using an accredited laboratory and EPA Method 1633 or a successor method approved by the Department of Environmental Quality (DEQ). It defines key terms such as biosolids, septage, agricultural land, and PFAS, and requires generators to test at a frequency set by DEQ, at least annually and no more than monthly, for specified PFAS compounds including PFOA, PFOS, PFHxS, and PFNA.
The bill establishes a tiered PFAS concentration framework for biosolids and septage, with interim thresholds based on the combined concentration of PFOA and PFOS. Materials below 20 μg/kg may be land-applied under existing rules; 20 to 50 μg/kg triggers reduced application rates and notice requirements; 50 to 100 μg/kg requires strict rate limits, enhanced recordkeeping, and source reduction planning; and above 100 μg/kg land application is prohibited. DEQ is authorized to adopt more protective thresholds, additional analytes, or total PFAS metrics by rule, and to coordinate with federal guidance and emerging science.
The bill also requires generators or applicators to provide landowners and farm operators with PFAS test results and tier information before application, and it requires written consent from the landowner or authorized operator before land application can occur. DEQ, in consultation with the Oklahoma Department of Agriculture, Food, and Forestry, must adopt additional safeguards for land used for food crops, animal feed, and livestock grazing, including possible soil, forage, or milk testing, use restrictions, crop limitations, and prohibitions in sensitive areas such as wellhead protection zones and shallow groundwater regions.
SB2141 would significantly expand state oversight of biosolids and septage management by adding testing, disclosure, recordkeeping, public reporting, and enforcement provisions. It authorizes DEQ to issue orders, suspend or revoke permits, and assess civil penalties for violations, with each day of noncompliance and each improper application event treated as a separate violation. It also requires a public online database of registered generators and applicators, summary PFAS results, and general application locations, and it directs the Environmental Quality Board to adopt implementing rules.
The available context shows no recorded committee debate or votes, so there is no documented split in sentiment. Based on the bill’s structure, the measure appears to be framed as a public health and farmland protection bill, with a generally precautionary approach to PFAS contamination. Likely points of contention include the cost and feasibility of frequent PFAS testing, the burden on wastewater facilities and applicators, the potential limits on beneficial land application of biosolids, and the use of interim thresholds before DEQ completes rulemaking.
SB2141 would add a new regulatory framework in Title 2 governing biosolids and septage land application in Oklahoma. It would require PFAS testing, disclosure, consent, record retention, public reporting, and DEQ enforcement authority, while also directing DEQ and the Environmental Quality Board to adopt rules on testing frequency, tier thresholds, application rates, and additional safeguards for sensitive agricultural uses. The bill would affect wastewater treatment facilities, septage haulers, biosolids generators, applicators, landowners, farm operators, and agricultural land receiving biosolids or septage.
There is no committee transcript or vote history provided, so no formal legislative sentiment can be measured from debate or roll calls. The bill’s text reflects a strong precautionary and protective posture toward farmland, water resources, and food production, suggesting support from environmental and agricultural protection advocates. At the same time, the regulatory and compliance burdens it imposes suggest it could draw concern from wastewater utilities, biosolids managers, and agricultural operators who rely on land application as a disposal or reuse method.
The main likely points of contention are the mandatory PFAS testing requirements, the frequency and cost of testing, and the tiered restrictions that could limit or prohibit land application of biosolids and septage. Wastewater and biosolids stakeholders may object to reduced application rates, public disclosure of application locations, and the possibility of permit suspension or civil penalties for noncompliance. Agricultural landowners and operators may support the disclosure and consent provisions but could be concerned about operational delays, liability, and restrictions on fertilizer-like soil amendments. Another likely issue is DEQ’s broad rulemaking authority to tighten thresholds or add analytes based on emerging science, which could create uncertainty for regulated entities.
