Mr. Dean Au, Chairperson and Members of the Windward Planning Commission Page 6 of 9 June 1, 2022 #13 Condition: This Condition shall be included in the Special Use Permit. Prior to start of quarry operation, the applicant shall obtain all applicable state Department of Health(DOH) Clean Air Branch Permits for the proposed use.
