attempt to treat the slopes would worsen the existing conditions. The commitment to provide immediate removal of any mass-wasting debris and the fact that al] surface drainage below the haul road is treated by the sediment control system satisfies the environmental protection requirements of Rule 4.03.1(c)(i). Blue Ribbon Coal Company did provide appropriate signage to ensure prevention of "harm to the public health and safety" as required by Rule 4.03.1(3)(c)(i). 2. The haul road was reclaimed by the operator in 1986. The road was reclaimed using material cast over the side during its construction. 3. The Hubbard Creek crossing, provided for the haul road, was installed in 1980. The calculations of Hubbazd Creek show the 9.5 ft diameter of the culvert will pass the 10-yeaz, 24-hour storm event of 838 cfs but not the 20-year, 24-hour event of 1675 cfs. The culvert is sized for 1149 cfs, therefore being 526 cfs under designed. Prior to the spring runoff in 1985, the operator designed and installed a dip section over the existing culvert. This dip section will safely pass the additional requirement of 526 cfs. For more information regarding the creek crossing see Section 2.5.3(4) and Appendix C in the permit application. 4. The creek crossing will be reclaimed once Pond No. 5 is no longer necessary and removed. B. Access Roads The Blue Ribbon Mine site has no access roads; therefore, this section does not apply. C. Light-Use Roads The Blue Ribbon mine has one light-use road on site, which intersects the haul road on the east side of Hubbard Creek beneath the mine bench. The road was used to perform maintenance on Ponds No. 1 and No. 2, and to provide access to other facilities. The road now allows for maintenance on Pond No. 5 and access to the Mine bench. 2. The light-use road will be reclaimed once Pond No. 5 is no longer necessary and has been removed. II. import Facilities -Rule 4.04 14
