30 Tex. Admin. Code § 330.129
The owner or operator shall maintain a source of earthen material in such a manner that it is available at all times to extinguish any fires. The source must be sized to cover any waste received for disposal not covered with six inches of earthen material. Sufficient on-site equipment must be provided to place a six-inch layer of earthen material to cover any waste not already covered with six inches of earthen material within one hour of detecting a fire. A site operating plan must contain calculations demonstrating the adequacy of the earthen material and to demonstrate that the type and number of equipment listed in the site operating plan will be able to transport the volume of earth required. The executive director may approve alternative methods of fire protection. The potential for accidental fires must be minimized by use of proper compaction and earthen material cover. A site operating plan must contain a fire protection plan that identifies the fire protection standards to be used at the facility and how personnel are trained. The operator must initiate procedures in accordance with the fire protection plan upon detection of a fire. For any municipal solid waste activity on a landfill that stores or processes combustible materials, such as solidification basins, brush collection areas, construction or demolition waste areas, composting areas, mulching areas, shredding areas, and used oil storage areas, the site operating plan must address fire protection measures specific to each individual activity. If a fire occurs that is not extinguished within ten minutes of detection, the commission's regional office must be contacted immediately after detection, but no later than four hours by telephone, and in writing within 14 days with a description of the fire and the resulting response.
