PERMIT#:M-1987-178 <br /> INSPECTOR'S INITIALS:ACY <br /> INSPECTION DATE:May 12,2022 <br /> OBSERVATIONS <br /> This inspection was conducted as part of the Colorado Division of Reclamation, Mining and Safety (Division) <br /> normal monitoring program. The 31 Road Pit is a 112c permitted site that includes a total of 60.5 permitted <br /> acres. The site is located just northeast of the intersection of C Road and 31 Road in Grand Junction, CO. Greg <br /> Monger of Parkerson Construction, Inc. represented the operator and accompanied Amy Yeldell of the Division <br /> on the inspection. <br /> The mine identification sign and affected area boundary markers are in place and in compliance with Rule <br /> 3.1.12. A sign is posted as you enter the permit boundary. The site is surrounded with visual berms as well as t- <br /> post periodically. The scale and scale house are located at the permit entrance. <br /> This site was active at the time of the inspection. To date the nearly entire permit area (58 ac)has been affected <br /> and the site is completely mined out. Remaining stockpiles of excavated on site remain. A crusher and several <br /> pieces of heavy equipment were on site though not operational at the time of the inspection. Material is <br /> imported from other pits to be crushed and sold for decorative rock. All stockpiles were neatly organized and <br /> free of erosion. Mining related supplies are neatly stored along the eastern boundary. The site is clean and free <br /> of trash and other miscellaneous debris. <br /> The southeast corner of the pit still has some contouring remaining on the highwall slopes. Approximately 600 <br /> ft. of the south slope is at a 1H: 1V. The majority of the eastern slope boundary is near vertical at 40 ft. high. A <br /> small amount of imported material has also been placed in the southeast corner for backfill, however <br /> significantly more material will be required to complete reclamation. The topsoil from this area has been <br /> stockpiled in a berm along the southern boundary. The slopes to the north already daylight and have no <br /> additional grading. The western permit boundary abuts to already release agricultural fields and also have no <br /> additional grading necessary. Extremely large overburden piles are stored primarily on the north side of the <br /> permit boundary. A slightly smaller topsoil pile is located on the most northern extent of the permit. Stockpiles <br /> are stable and erosion free and sloped approximately 21-1: IV. <br /> Upon completion of final reclamation all slopes will be contoured to a 31-1: 1V or less and revegetated with a dry <br /> rangeland seed mix. The pit floor will be returned back to agricultural use which will require placing of <br /> sufficient overburden (12") and then topsoil (12") material to support a crop. An established crop need not be <br /> required however the fields need to be ready for use to be eligible for release. <br /> At the base of the backfilled slopes is a French train to intercept run on water from the irrigated fields to the <br /> south of the mine area. This drain diverts water through the pit so that no groundwater is exposed while mining. <br /> There was no exposed ground water at this pit. <br /> The Division currently requires a financial warranty amount of$221,110 for this site. The bond has not been <br /> recalculated since SI-2 in 2018. In an effort to ensure the Financial Warranty adequately, reflects the actual <br /> current cost of fulfilling the requirements of the approved reclamation plan the Division will be updating the <br /> reclamation cost estimate. If the current bond is found to be insufficient the Division will send a Notice of <br /> Surety Increase under a separate cover. <br /> No problems or violations were noted during this inspection. <br /> Page 2 of 6 <br />
