IV. CONSTRUCTION SUMMARY <br /> The request for Documented Quote resulted in 3 bids being received. The lowest bid was rejected by <br /> Purchasing as being a non-responsible bidder, based upon unsatisfactory performance at Coal Basin in <br /> 1998. The Project was awarded to the lowest responsible bidder. <br /> Contractor used back pack, ATV and Jeep mounted spraying equipment to treat approximately 25 <br /> discontinuous acres of noxious weed infestation. Species of interest included Canadian and Plumeless <br /> Thistle, Oxeye Daisy and Hounds tongue. Tordon 22K was applied at a rate of 1 quart per acre. The Bid <br /> package required that target species only be treated, with non-target species disturbed as little as possible. <br /> Therefore, spot spraying of target species was required,creating a very labor intensive Project. <br /> V. FUTURE MAINTENANCE <br /> The Project area will need additional treatment in 2001 and, likely, 2002. Established monitoring points <br /> (transects located on the Sutey Refuse Disposal Area, an open field north west of the Sutey, and on the <br /> Overland Conveyor Corridor) should be monitored to help determine future needs. <br /> The upper' of the central portion of the Old Refuse Pile will need additional, fairly aggressive treatment <br /> in the future. <br /> VI. SUMMARY <br /> This Project was part of an on-going integrated weed management program at Coal Basin. Use of biologic <br /> controls (goats)were also employed at some areas not chemically treated. On going treatment of target <br /> species will be necessary in order to maintain the success realized by the past 3 years of treatment. <br /> Coal Program vegetation experts should monitor the site for noxious weed growth at the established <br /> reference areas. <br /> Project Manager Steve Renner <br /> Date 12-05-00 <br /> M:\imp\closeout\coalb00weed.doc <br />
