In the event that an application is required to be reviewed by more than one Board, then, in such event and to the extent practicable, both Boards shall use the same consultant, who shall, in such case, to the extent practicable, prepare one report providing data, information and recommendations requested. In all instances, duplications of consultants' reports or services shall sought to be avoided wherever practicable in order to minimize the cost of such consultants' reports or services to the applicant. The above fees are in addition to any and all other fees required by any other law, rule or regulation.
