Covering your truckload while on the way to the landfill is more than just a courtesy to other drivers itâs the law. If thatâs not enough incentive, consider this: Gila County Public Works will levy an additional $10 âunsecured load feeâ if you arrive at Buckhead Mesa Landfill without a tarp or other cover securely containing debris or loose bags of trash in your truck. Grocery bags, paper, boxes and other airborne debris littering Highway 87 and the Buckhead Mesa Landfill road spurred reinforcement of Gila Countyâs adherence to Arizona law 28-1098.A, which states âa person shall not drive or move a vehicle on a highway unless the vehicle is constructed or loaded in a manner to prevent any of its load from dropping, sifting, leaking or otherwise escaping from the vehicle.â
