used have been analyzed and Found to be non-toxic and non-acid Forming. Data <br />From chemical analysis of representative surfacing materials are presented in <br />Table 3.7-1. The materials are sufficiently durable for the conditions encoun- <br />tered a[ this mine. <br />3.7.2.5 Maintenance <br />The haulroads at the Trapper Mine are maintained in good condition by grading the <br />road surface and shoulders, cleaning and re-establishing ditches, cleaning cul- <br />verts, dust suppression, removing snow and mud, reapplying additional surfacing <br />materials, maintaining traffic control devices and spraying to control undesir- <br />able roadside plant growth. These endeavors are carried out as necessary and the <br />haulroads are inspected almost continuously during coal haulage periods to insure <br />that the maintenance is accomplished. Road watering is used for dust suppression <br />as an integral part of our fugitive dust control emissions plan. Other methods <br />of dust suppression may be used in the future, such as adding palliatives to the <br />• road water, or paving. <br />Portions of haulroads damaged by events such as floods or earthquakes will not be <br />used for hauling coal until the road has been repaired. <br />3.7.2.6 Restoration <br />When no longer required, haulroads and associated structures are removed and the <br />area is reclaimed. Culverts and drainage control structures, salvageable rip-rap <br />and salvagable road surface materials are removed. The road bed is ripped and '. <br />road cuts, embankments and berms are graded to blend into the surrounding topo- <br />graphy and reestablish the natural drainage of the area. Disturbed areas are <br />then re topsoiled and revegetated according to Sections 3.2 and 3.6. Access <br />points to closed roads will be posted to prohibit vehicular travel over the area. <br />If needed, cross drains, water bars, etc. will be constructed during restoration <br />to aid in stabilizing the reclaimed area. <br /> <br />3-170 <br />REVISED FER ~ .~ "~ j <br />
