Relating to fluid oil and gas waste and products and byproducts of that waste.

SB 1399 defines "treated product" as waste processed for beneficial use (e.g., filtered or refined oil/gas waste). It changes ownership rules: when waste is transferred for treatment, the recipient owns it until the treated product is transferred for use. The bill also exempts parties who process waste for beneficial use from legal liability for harm caused by subsequent use of the treated product or its byproducts. This directly affects oil/gas waste handlers, treatment facilities, and companies using treated products. The bill focuses on clarifying ownership and limiting liability for waste processing activities.
