of 30 feet. The Hilfiker treatment was applied between road design stations 29+50' and <br />36+50'. Unretained cut slopes will not exceed a maximum slope gradient of 1.25h:I.Ov <br />(horizontal to vertical) unless an appropriate slope stability monitoring program has been <br />approved by the Division. With an approved monitoring program, cut slopes will be <br />allowed to reach a maximum slope gradient of 1.0h:1.Ov (horizontal to vertical). The <br />stability analysis determineda minimum operational static slope safety factor adjoining the <br />upgraded haul road of 1.72. <br />As required in the approved reclamation plan, the operator removed and reclaimed that <br />portion of the haul road constructed to connect the existing public access road to the <br />proposed portal bench embankment across East Roatcap Creek (design plan road Station <br />32+50' to 38+50'). <br />The fordofan ephemeral stream with a watershed of at least one square mile was approved <br />by the Division since it would not seriously alternormalwater flow, contribute to sediment <br />load, or cause adverse effects to fish or wildlife. The ford is located on East Roatcap Creek <br />where the BLM road, used to access the West Mine fan facilities, crosses this creek. <br />The R.O.M. stockpile haul road was constructed between May 10, 1976 and May 4, 1977. <br />Minor Revision No. 66 formally included this haul road into the permit application. The <br />road had been constructed on mainly fill material. It was surface treated with 12 inches of <br />gravel in June of 1992 and certified. A portion of the road was reclaimed when the R.O.M. <br />area was reclaimed. The remaining portion of the R.O.M. haul road will be reclaimed as <br />well. <br />The haul road leading to the West Ridge Waste Pile was constructed in 1984 and had <br />originally been designated as an access road. Hover, the road was upgraded to a haul <br />road and a certified relevant showing, pursuant to Rule 4.03.1(1)(d)(ii) was submitted as <br />part of the Permit Renewal No. 3 adequacy. The certification states that, with the <br />information that is available, the haul road meets the specifications of Rule 4.03.1, except <br />for grade requirements. T he 400 feet of road has an overall grade of 12.5 percent, in excess <br />of the 10 percent upper limit for overall grade, of Rule 4.03.1(3)(a)(i) and also in excess of <br />the maximum grade of 10 percent for any 300 foot section within any 1,000 foot length, <br />set forth in Rule 4.03.1(3)(a)(iii). The Division granted BRL's request to accept this <br />alternative design, as allowed in Rule 4.03.1(1)(e), based on the performance history of <br />this road over the years. <br />II. Support Facilities - Rule 4.04 <br />The mine facilitiesat the Bowie No. 1 Mine were predominately locatedin three areas - the <br />main East Mine and the Run -of -Mine (ROM) stockpile area across the way on Steven's <br />Gulch Road, the Bowie No. 1 West Mine andthe train loadout. Three other miscellaneous <br />structures are found within the permit area. They include the guard shack at the entrance <br />to the East Mine from Steven's Gulch Road, the superstructure of which has been removed <br />for reclamation, the 500,000 gallon water tank and well house at the Steven's Gulch well <br />field, and the Bowie No. 1 West Mine pipeline. These facilities are described in Section <br />2.05, and maps are found in Volume 8A of the PAP. <br />20 <br />
