(1) Waste tire monofill facilities shall comply with Title 14, California Code of Regulations, Division 7, Chapter 3, Article 5.5 and with Title 14, California Code of Regulations, Division 7, Chapter 6, Article 8.5.

(2) Waste tires disposed in a waste tire monofill shall be altered waste tires or shall be otherwise permanently reduced in volume prior to disposal in a manner approved by the EA and the Board on a case-by-case basis. Waste tires disposed in a tire monofill shall also comply with the following specifications, unless alternative specifications are approved pursuant to subsection (b)(10):

(3) Representative samples of altered waste tires to be disposed in a waste tire monofill shall be collected and analyzed for gradation and protruding wire on a monthly basis, or less frequently if approved by the EA and the Board, to ensure compliance with subsections 17346.3(b)(2)(A), (B), and (C). Representative samples of cover to be disposed or utilized at a waste tire monofill shall be tested to ascertain compliance with the limitation on organic matter set forth in subsection 17346.3(b)(5) of this Article 5.4. Records of the results of these samples shall be maintained in the records required by Section 17346.4 of this Article 5.4.

(4) The last lift of altered waste tires disposed in a waste tire monofill shall be compacted to provide a flat and stable surface.

(5) Waste tire monofill cells shall not exceed a maximum depth of 20 feet (6 m), and a maximum cell area of 12,500 square feet (1161 square meters). A minimum distance of 2 feet shall be maintained between tire shreds in adjacent cells. Intermediate cover shall be placed to wholly encapsulate each monofill cell. Intermediate cover shall consist of soil with less than 5% organic matter as determined by a loss on ignition test (ASTM D 2974-00) and compacted to the maximum density obtainable at optimum moisture content, plus or minus 3 percent, to obtain a stable surface, using methods that are in accordance with accepted engineering practice.

(6) The active face of not more than two (2) cells shall be uncovered at any given time within a waste tire monofill facility.

(7) A minimum of 6 inches (152 mm) of cover shall be placed over the entire working face at the end of each operating day if: (A) the working face is to remain open and inactive for longer than 24 hours; or (B) when there is precipitation. The cover shall consist of the same material used as intermediate cover.

(8) If more than one waste tire monofill cell is stacked vertically, temperature sensors shall be installed within the underlying cells to monitor cell temperatures. The operator shall submit a plan that sets forth the location and frequency of sensor placement for approval by the EA and the CIWMB. In addition, a fire prevention plan shall be in place to address any zones, which experience sustained elevated temperatures to reduce temperatures to safe levels. Both plans shall be made part of the Fire Prevention, Control and Mitigation Plan, which is defined in Section 17346.5(b)(1). Records of these results of elevated temperature shall be maintained in the records required by Section 17346.4 of this Article 5.4.

(9) An adequate stockpile of cover and equipment, as required and approved by the EA and the Board, shall be available in the event of fire to insure a cover of a minimum depth of 3 feet on all waste tires, crumb rubber and rubber fines at the waste tire monofill facility exposed to the atmosphere.

(10) The operator may propose to the EA and the Board alternative operating criteria to those specified in subsections 17346.3(b)(2) through (b)(9) together with information supporting the proposal. The EA and the Board may approve such alternative criteria only if the EA and the Board determine that the alternative criteria protect the public health and safety and the environment at least as effectively as the criteria specified in subsections 17346.3(b)(2) through (b)(9).

(11) Any mining or excavation of waste tires from a waste tire monofill shall be in accordance with a site-specific excavation and materials management plan approved by the EA and the Board.

(12) For the purposes of this Article, in addition to the requirements of Title 27, California Code of Regulations, Section 20610 (Training), site personnel shall be trained in fire safety, prevention and suppression.
