|(a) This subchapter does not preempt local ordinances regarding the management of used or scrap tires that are as or more stringent than the regulations in this subchapter. All persons or facilities regulated by this subchapter must comply with all applicable local ordinances that are not inconsistent with the regulations in this subchapter. A local ordinance is not inconsistent with this subchapter if a regulated person or facility can simultaneously comply with both the state and local requirements. (b) This subchapter applies to persons that are involved in the generation, transportation, processing, storage, utilization, and disposal of used or scrap tires or tire pieces that are classified as municipal solid waste, recyclable materials, or inert fill materials. This subchapter does not apply to whole used or scrap tires that are classified as industrial solid waste. (c) All used or scrap tires or tire pieces, except for tires collected incidentally by municipal solid waste collection vehicles, are subject to manifesting by generators according to the requirements in §328.58 of this title (relating to Manifest System). (d) Scrap tires that are off-the-road tires intended for use on heavy machinery, including, but not limited to, an earth mover/dozer, a grader, or mining equipment are exempt from the time frame requirements to be split, quartered, or shredded when stored at a registered storage site or a permitted landfill. These tires must be shredded, split, or quartered prior to disposal in a manner acceptable to the executive director. The executive director may grant exceptions to this requirement as warranted by the circumstances.
