(a) Except with the express written permission of the person entitled to control the disposition of the remains, no person shall do any of the following:

1. (1) Hydrolyze the remains of more than one person at the same time in the same hydrolysis chamber, or introduce the remains of a second person into a hydrolysis chamber until dissolution of any preceding remains has been terminated and reasonable efforts have been employed to remove all fragments of the preceding remains.

3. (3) Place hydrolyzed human remains or other remains of more than one person in the same container or the same interment space. This paragraph shall not apply to the following:

   1. (A) Interment of members of the same family in a common container designed for the hydrolyzed human remains of more than one person.
   2. (B) Interment in a space or container that has been previously designated at the time of sale as being intended for the interment of remains of more than one person.
   3. (C) Disposal in a dedicated cemetery of residue removed from processing equipment.
