How will the quarry control the tracking of mud and dirt from the haul trucks onto the highway?

The haul trucks are loaded in the quarry processing area which is some 1000 feet up the access drive from Highway 119. Brannan will be paving the access drive from Highway 119 a distance of at least 500 feet and will be installing grates or other devices in the access drive to knock mud and dirt off the trucks before they enter onto Highway 119. This improved access drive will be regularly maintained by sweeping or washing. These measures should minimize any tracking of mud and dirt onto the highway. But, additional paving and other measures will be taken if necessary.  more
