30 Tex. Admin. Code § 324.15
Whenever there is a catastrophic release or discharge of used oil and used oil reaches the environment, corrective measures must be immediately taken by the responsible person to adequately protect human health and the environment from potential damages. A spill of used oil in an amount sufficient to cause a sheen on water or a spill of automotive engine used oil or a mixture of automotive used oil and other used oil of 25 gallons or more that goes into the environment at a do-it-yourselfer used oil collection center should be reported to the commission as soon as possible and not later than 24 hours after discovery. (See 40 CFR §279.43(c) for discharges during transport.) A spill or overfill of used oil at an underground storage tank that results in a release to the environment that exceeds 25 gallons, or that causes a sheen on nearby surface water shall be reported and handled as in §334.75 of this title (relating to Reporting and Cleanup of Surface Spills and Overfills). All other used oil spills must be reported in accordance with other applicable commission requirements and agreements. The responsible person may notify the commission in any reasonable manner including by telephone, in person, or by any other method approved by the commission.
