26, Township 6 North, Range 87 West (Map 21). The area adjacent to the BMG will <br />be the primary source of riprap, and the other area will be used as a secondary <br />source, especially where riprap is required to stabilize areas that are in close <br />proximity to these borrow areas. Sun Coal Company will use the secondary riprap <br />borrow areas when the haul distance is less than 1,000 yards. <br />The primary riprap source has a reserve of approximately 1,500 cubic yards, <br />whereas the secondary source has approximately 75 cubic yards. It is difficult <br />to anticipate the amount of riprap required to control erosion until the need <br />arises. Sun Coal Company anticipates approximately 25 cubic yards will be used <br />annually, or approximately 250 cubic yards during the bonding period. <br />When borrow material is required from the primary borrow site, all avail- <br />able topsoil from the designated area will be removed and stored for reclama- <br />• tion. After the riprap has been removed, the disturbed area will be graded to <br />blend with the adjacent topography, topsoiled, and revegetated (Table 2.05.4-2) <br />in accordance with approved reclamation procedures. Riprap will be removed to <br />disturb as small an area as practicable, and borrow activities will be conducted <br />in such a manner as not to limit or interfere with the landowner's access or <br />utilization of the area adjacent to the riprap borrow area. <br />When riprap is borrowed from the secondary source, the material will be <br />picked from the surface by hand and will be reclaimed as previously di cussed. <br />Revegetation - Monitoring Plan <br />Monitoring activities include the following: <br />. Conducting cover transect surveys. <br />. Obtaining production samples. <br />. Evaluate trends and diversity in vegetation. <br />• <br />- 380 - (Rev. 5/86) <br />
