5. Application of gravel chips to road surfaces will begin 75 to 100 feet from intersections, driveways, turn lanes, in and out lanes on specified parking areas and other areas as designated and continue through the operational area.

6. Application will stop when vehicle is safely beyond the vehicle maneuver area.

7. Amounts and quantities of chip gravel applied per pass will be, under normal conditions, of a quantity and spread pattern across the road surface that provides motor vehicle with significantly improved vehicle traction and driving safety characteristics.

Snow Dump Operations and Maintenance During a winter season, snow dumps are operated for the storage and disposal of snow.

The locations are:

Located in the open area north of Gaffney near west of railhead loading dock Located in the open area on the North, East and West of Building 3380 Located in the open area north side of Oak Avenue south 3728 Located in the open area south 3584 on Meridian

Operations include:

Keeping entrances and driveways clear and open to truck traffic.

Keeping snow pushed or blown into high piles.

Keeping area free of litter and trash.

After breakup and when snow dump has melted and is free of snow all litter and trash shall be removed.

YTA – Snow Removal Snow plowing operations shall commence when snow fall is estimated to accumulate greater than four (4) inches of snow on the roadway in the deepest snowfall area.

Snow plowing operations per snowstorm or snow drifting event shall be completed within 72 hours after the end of the event. Achieve full winter road width with definition on the YTA Main Route within 24 hours after the end of the storm and within 72 hours for the remainder of the roads. Do not plow snow beyond the drivable road surface.

Hard Pack Removal and Break-up Hard pack removal will most likely be necessary mid-winter, and again just before spring. During breakup the road shall change from being defined by a snow step at the shoulder to being defined by cut ditches. Make every reasonable effort to prevent water or slush from forming or accumulating or standing on the road or on the shoulders. Remove hard pack and ice before it turns to slush. Ensure that ditches and culverts drain freely.

Graveling or Sanding Graveling is required on hills, curves, intersections and roadways to include the bridge on Manchu Lake Trail over Moose Creek, approach areas to range facilities and roads and parking lots.

Serration of hard pack is an approved technique for maintaining traction whenever it is feasible.

DTA – Snow Removal Snow plowing operations shall commence when snow fall is estimated to accumulate greater than six (6) inches of snow on the roadway in the deepest snowfall area. Snow plowing operations per snowstorm or snow drifting event shall be completed within 72 hours after the end of the event. Do not plow snow beyond the drivable road surface.

Wing back snow at the shoulders to provide additional snow storage as needed. Do not plow snow beyond the drivable road surface. Snow shall not be plowed into ditches on roadways and into the surrounding area adjacent to any parking lot unless it is fenced and removal of accumulated snow becomes a necessity to maintain adequate parking.

Hard Pack Removal and Road Shoulder Definition Hard pack removal shall be monthly beginning November, continuing through March. During breakup the road shoulder definition shall change from being defined by a snow step at the shoulder, to being defined by cut ditches. Make every reasonable effort to prevent water or slush from forming or accumulating or standing on the road or on the shoulders. Remove hard pack and ice before it turns to slush. Ensure that ditches and culverts drain freely.

Snow Fences and Sanding Installation of snow fencing shall be limited to areas of historically deep snow drifting. These materials will be spread on dangerous hills, curves, intersections, roadways, and approach areas to range facilities roads and parking lots. Sanding shall allow for reasonable braking on all roads at all times. Serration of hard pack is an approved technique for maintaining traction whenever it is feasible.
