(e) reason for the disposal.

(9) A licensee must provide a minimum of 72 hours' notice in the seed-to-sale tracking system prior to rendering the marijuana item unusable and disposing of it.

(10) After the expiration of the 72-hour period in (9), a licensee may dispose of marijuana waste other than usable marijuana as defined in 16-12-102, MCA, without rendering it unusable pursuant to (3) by releasing it to a third-party contractor to render it unusable.
