Owner-operated Semi-tractors When transporting biosolids to field application sites using owner/operator semi tractors, the contractor will be performing tasks normally associated with the transportation of biosolids in the District’s Metrogro program. These tasks include, but are not limited to the following: loading District owned trailers at the District’s loading facility (including connecting/disconnecting transfer hose and operating controls and valves at the loading facility), safe and respectful transport, unloading into a nurse tank at the field application site (including connecting/disconnecting transfer hoses and operating any controls or valves during the unloading process), completing and turning in trip tickets on a daily basis, assisting as necessary with the daily placement of traffic control sign at the field application sites, assisting as necessary with directing traffic around the unloading area while transferring the load into the nurse tank, moving and proper set up of the nurse tank, assisting with field setup activities including placement of nurse tanks, assisting with routine trailer maintenance, cleaning the trailer when appropriate (using cleaning supplies furnished by the District), and maintaining both loading and unloading sites in a clean and orderly fashion. The District’s trailers are fully enclosed and designed for transport of a liquid material. The maximum trailer capacity is approximately 6,000 gallons, with a typical working capacity of approximately 5,800 gallons. The weight of a trailer loaded to its working volume would be approximately 63,000 pounds. Trailer length could range from approximately 35 to 40 feet. The trailers are equipped with a pressurevacuum transfer pump which is located at the front end of the trailer. The pump is used to assist with loading and unloading the trailer. The owner-operated semi-tractors must be equipped with a wet kit, which will be used to operate the pressure-vacuum transfer pump. The wet kit shall have a capacity of at least 17 gpm at 1000 rpm. The District will supply two-way radios and will arrange for their installation in the contractor’s semi tractors for communication purposes. The District will be responsible for paying the monthly air time charges for the radios. The owner-operated semi-tractors must meet all DOT safety and operational requirements. At the contractor’s expense each vehicle shall undergo a DOT inspection for the year that hauling occurs. Documentation of a successful inspection must be supplied to the District before the vehicle will be allowed to participate in the program. The total and distributed weight of the semi-tractor/trailer combinations must allow for the trailer to legally carry its working capacity of approximately 5,800 gallons on the interstate highway system and state, county and local roads. It will be the contractors’ sole responsibility to ensure that his/her trucks and drivers are properly licensed in accordance with the law, including a valid Class A Commercial Driver’s License (CDL) with a tanker endorsement. The semis shall be inspected by the District Staff for proper hookups and operation with Metrogro trailers.
