Article 5.4 - Waste Tire Monofill Regulatory Requirements
Section 17346.6 - Design and Construction Standards

(a) The waste tire monofill shall be constructed in accordance with design plans and specifications prepared, signed, and stamped by a civil engineer registered by the State of California, pursuant to Section 6762 of the Business and Professions Code.

(b) As specified in Section 17346.5 of this Article, operators of waste tire monofills shall prepare a Fire Prevention, Control and Mitigation Plan. As part of this plan, an emergency containment system that limits the flow of any contaminated liquids resulting from a fire in the tire monofill must be provided. The emergency containment system must contain any contaminated liquids resulting from a fire in the waste tire monofill and fire suppression for a period consistent with the implementation of the Fire Prevention, Control and Mitigation Plan. The emergency containment system may be the existing natural geologic condition or may be constructed (utilizing clay or composite material together with a protective operations layer). The emergency containment system shall also include a collection system to remove any contaminated liquid that accumulates within the monofill in the event of a fire within or proximate to the tire monofill. The emergency containment system must be able to withstand breaching or rupture due to temperatures and other conditions that may result from a fire within the tire monofill and from activities undertaken to extinguish a fire within the tire monofill or to remediate any hazard or risk of hazard to the public health and safety or the environment due to a fire within the tire monofill.

(c) Waste tire monofills shall be designed and constructed to minimize water from entering or accumulating in fill areas, or ponding on cells. Storm water may be temporarily collected in lined dewatering sumps that are located on the cells. The design and construction of the tire monofill must allow for the removal of storm water and water that accumulates in the monofill as quickly as necessary to minimize the risk of fire within the monofill, as determined by the EA and the Board.

(d) The operator of a waste tire monofill shall implement a construction quality assurance (CQA) program to ensure compliance with the above requirements.
