. ~ ~ . <br />March 2007 Hayden Gulch Terminal, Inc. * Hayden Gulch Mine - 2006 Annual Reclamation Report •Page 3 <br />Approximately 69.4 acres of the 97 disturbed acres have been seeded with Seed Mix No. 4 <br />(temporary stabilization mix). Included in this acreage are the facilities area, the three <br />topsoil stockpiles and the railroad spur and loop alignments as shown on Figure 1. The <br />temporary stabilization seeding was completed in conjunction with facilities construction <br />activities (circa 1979/1980) by H-G Coal Company, the previous owner/operator/ <br />permittee. <br />2.2 WEED CONTROL <br />The permit area was surveyed for noxious weeds in 2006 to determine the need or level of <br />retreatment for previously treated areas. Canada thistle (Cirsium arvense) and Houndstongue <br />(Cynoglossum oJjrcinale) were the primary target species of control, however, yellow toadflax <br />(Linaria vulgaris), Dalmatian toadflax (Linaria genistifolia), hoary cress (Whitetop, Cardaria <br />draba) and leafy spurge (Euphorbia esula L.) were also identified and treated. Figure 1 shows the <br />noxious weed infestation areas that were treated in 2006. <br />The applied herbicide consisted of a tank mix of 0.5 gallons of Tordon 22K and, either 0.5 gallons <br />of 2,4-D or 4 ounces of Milestone with 16 ounces of Activator 90 and 50 gallons of water. <br />Control areas were sprayed in June and, then again in September. A spot spray gun was used to <br />concentrate control activities on target areas, reducing potential impacts to adjacent desirable <br />vegetation. The weed control areas will continue to be monitored in 2007 for effectiveness and <br />necessary retreatment. <br />H}'dro-Environmental Solutions, Inc. <br />P.O.
