(d) The following requirements apply to on-site storage by generators: (1) Generators may store used or scrap tires or tire pieces at the location where they are generated, provided the total number of used or scrap tires does not exceed 500 used or scrap tires (or weight equivalent tire pieces or any combination thereof) on the ground or 2,000 used or scrap tires (or weight equivalent tire pieces or any combination thereof) in trailers. (2) Generators who store used or scrap tires in excess of 500 used or scrap tires (or weight equivalent tire pieces or any combination thereof) on the ground or 2,000 used or scrap tires (or weight equivalent tire pieces or any combination thereof) in trailers shall be required to obtain a scrap tire storage registration pursuant to §328.55 of this title (relating to Registration Requirements); (3) Retailers and wholesalers who sell good used tires as a commodity shall do so only from stock that has been sorted, marked, classified, and arranged in an organized manner for sale to the consumer, or has been designated on the manifest as removed for reuse by a registered transporter.
