An open-enrollment charter school or private school may also adopt and implement a policy regarding the maintenance, administration, and disposal of opioid antagonists. If a school adopts a policy, the school may apply the policy:

• only at campuses of the school serving students in grades 6 through 12;
• or at each campus of the school, including campuses serving students in a grade level below grade 6.

A policy adopted under this section must:

• provide that school personnel and school volunteers who are authorized and trained may administer an opioid antagonist to a person who is reasonably believed to be experiencing an opioid-related drug overdose;
• require that each school campus subject to a policy adopted under this section have one or more school personnel members or school volunteers authorized and trained to administer an opioid antagonist present during regular school hours;
• establish the number of opioid antagonists that must be available at each campus at any given time; and
• require that the supply of opioid antagonists at each school campus subject to a policy adopted under this section must be stored in a secure location and be easily accessible to school personnel and school volunteers authorized and trained to administer an opioid antagonist.

The executive commissioner of the Health and Human Services Commission, in consultation with the commissioner of education, shall adopt rules regarding the maintenance, administration, and disposal of opioid antagonists at a school campus subject to a policy adopted under this section. The rules must establish:

• the process for checking the inventory of opioid antagonists at regular intervals for expiration and replacement; and
• the amount of training required for school personnel and school volunteers to administer an opioid antagonist.
