possibility of herbicide resistance, and minimize persistence and mobility of <br />herbicides in the soil. When wetlands or Other Waters of the U.S. are present in the <br />project area, preference will be given first to cultural, mechanical and biological <br />weed control methods before chemical ones. Weed control methods and practices <br />will be timely applied to maximize their effectiveness. When herbicides are used <br />they will be applied in a manner that conforms to applicable federal, state and local <br />laws. <br />1.3.1 Cultural Control <br />Germination and establishment of noxious and pest weeds can be significantly <br />reduced by following accepted reclamation and vegetation management techniques <br />that favor the growth of desirable plants. These include rapid seeding and <br />establishment of disturbed areas with selected seed mixtures, maintaining optimum <br />fertility and moisture levels, planting at optimum density of pure live seed ( "PLS ") <br />and selecting suitable species for revegetation. <br />GCC's approved revegetation plan meets cultural control requirements. This plan <br />requires contemporaneous revegetation of disturbed areas through the proper <br />application of either temporary or permanent seed mixtures, fertility amendments <br />and mulch materials. Approved revegetation operations are designed to ensure <br />timely successful revegetation of disturbed areas with suitable plant materials. <br />1.3.2 Mechanical Control <br />Mechanical control of noxious and pest weeds can be an effective tool to physically <br />disrupt their growth and seed development. GCC may use a combination of <br />mechanical methods including tilling or disking, mowing, hand -held weed <br />trimmers, mulching, hand - pulling, hoeing, burning or flooding.
