Under what conditions would a non-terne plated used oil filter be excluded from the definition of hazardous waste?

Non-terne plated used oil filters that are not mixed with listed wastes are excluded from the definition of hazardous waste when they have been gravity hot-drained using one of the following methods: puncturing the filter anti-drain back valve or the filter dome end and hot-draining; hot-draining and crushing; dismantling and hot-draining; or any other equivalent hot-draining method that will remove the used oil (Part 261.4(b)(13)). The term "gravity hot-drained" means that the oil filter is drained near engine operating temperature and above room temperature (57 FR 21524, 21532; May 20, 1992). Once the filters have been drained using one of the methods specified in ?261.4(b)(13), they are no longer subject to used oil regulation and are excluded from the definition of hazardous waste (Memo, Cotsworth to Harris; June 2, 1998 (RCRA Online #14183)).
