Applicable road performance standards under Rule 4.03 are addressed by the following: <br />• All roads are subject to the BACT requirements of MCM's existing air emissions permit <br />• Roads to be reclaimed are subject to the postmining land use requirements, as described in this PAP <br />• All roads are designed and maintained to assure utility and safe use consistent with applicable provisions of <br />Rule 4.0 <br />In order to determine compliance with applicable performance standards, CTL- Thompson, Inc. was requested to <br />evaluate all access and haulage roads. The resulting report, included in Exhibit 17, Road Certification, verified that all <br />roads are in compliance with the applicable performance standards. <br />Main Haulroad - As shown on Map 27, there are a number of haulroads within the Mine Permit Area. Although the <br />haulroads have been used mainly to transport development waste and coarse reject from the rotary breaker to the <br />waste disposal areas, they were generally designed and maintained to haulroad standards. <br />Haulroad A is an existing road that was built prior to SMCRA. The road was constructed in accordance with accepted <br />road construction practices at the time, and as part of the road design and construction, culverts were placed at key <br />drainage crossings. Map 27A shows the road location, and Figure 56A provides a typical road cross - section. Peak <br />flow information obtained from Trapper Mine's permit indicates peak flows in West and East Buzzard Gulches are <br />178 cfs and 13 cfs (from Trapper's East Buzzard #1R Pond), respectively. Existing culverts in both of these drainages <br />and on an unnamed tributary east of East Buzzard Gulch are 16 -inch CMP. Flow calculations by RAG engineers <br />indicated that the West and East Buzzard Gulch culverts should be 60 and 36 inches in diameter, respectively. The <br />remaining culvert (on unnamed tributary) is more than sufficient to handle the runoff from the small associated <br />drainage area. <br />Haulroad A joins Moffat County Road 107 in the southwest corner of Section 28, T6N, R91W, as shown on Map <br />27A. Historically, Haulroad A was utilized to transport coal from the existing coal - handling facilities to its <br />intersection with County Road 107. While County Road 107 was not transferred under the previously referenced <br />agreement, the road agreement does allow for use of County Road 107 for coal haulage. Since no surface mining <br />activities are associated with the Williams Fork Mines, and any recent coal shipments from the property have been by <br />rail; the main haulroad has not been used for many years for coal haulage. Waste material as well as coarse reject has <br />been hauled to the waste disposal site, and highway -legal trucks use the main haulroad to access Highway 13. <br />The existing portion of County Road 107, which crosses Trapper's Permit Area, overlies an existing MCM State Coal <br />Lease, and under this lease, MCM has the right to use the surface to the extent needed to develop, mine, and transport <br />the coal. Trapper is aware of these rights, and prior to initiation of any coal haulage, an agreement would be reached <br />with Trapper for use of the road. If MCM utilizes the road for coal haulage, it will be MCM's responsibility to <br />maintaining the haulroad in compliance with applicable regulations until such time as it is reclaimed or left as a <br />permanent postmining road. If it is determined that the road should become part of the postmining road network, a <br />revision will be submitted to the Division requesting retention of the road. <br />Prior to any future use of Haulroad A for coal haulage, additional work will be done on the haulroad to meet current <br />road standards, including replacement of culverts with adequately sized culverts, any supplemental drainage work <br />required, testing the existing road base to determine the amount of surfacing that will be required to handle anticipated <br />weight loads, and re- surfacing of the road with durable material. The fills required at the culvert locations will be <br />constructed of select native materials, excluding topsoil and vegetation, and will be placed in one -foot lifts and <br />compacted to 95 percent Proctor density. The profile of the road is shown on Figure 56B, along with culvert and <br />respective fill locations. The outslopes of the fill will be 1.511:1 V or flatter and culvert inlets will be protected by pre- <br />fabricated inlet sections, wing- walls, or rock headwalls. Figures 56C and 56D provide additional details on the fills <br />that will be constructed in both of the drainages. The detail shown for the 60 -inch culvert fill indicates that extra <br />material will be generated when the culvert is replaced by the larger culvert. This material will be redistributed over <br />the existing road and then surfaced with a durable material. <br />TR14 -36 2.05 -15 Revised 03/04/14 <br />
