§ 150.22  DUST CONTROL MEASURES.
   (A)   Wet suppression control system equipment shall be installed and maintained at all crushing and screening equipment, and conveyor transfer points, except for the wet section of the processing plant when water is added to the process in sufficient quantities to clean the stone free of all fine particles.
   (B)   (1)   The access road from any adjacent public street or highway shall be paved for a distance of at least 500 feet from the edge of that public street or highway.

      (3)   The paved portion of the access road, including any speed bumps and any paved parking or pull-off areas shall be vacuumed or washed free of any dirt whenever needed to prevent the generation of dust, but no less than once each week during periods of operation.

   (E)   Loading of stone trucks, hoppers, or bins, either in the quarry or in and around the processing plant shall be done in a manner to minimize the free fall distance.
