PERMIT#: M-2006-039 <br /> INSPECTOR'S INITIALS: ACY <br /> INSPECTION DATE: April 13,2016 <br /> OBSERVATIONS <br /> This inspection was conducted as part of the Colorado Division of Reclamation, Mining and Safety (Division) <br /> normal monitoring program. The North Clear Creek Construction Materials Mine is a 110c permitted site that <br /> includes a total of 8 permitted acres. This site is located approximately 17 miles northwest of Debeque, <br /> Colorado and is accessed from Garfield County Road 211 (North Clear Creek Rd). Richard Grubbs and Vince <br /> Guinta represented Chevron USA, Inc. and accompanied Amy Yeldell of the Division on the inspection. <br /> The mine identification sign and affected area boundary markers are in place. The mine sign is posted at the <br /> base of the topsoil pile in the northwest corner of the mine. The permit boundary is delineated by t-posts. It is <br /> noted that the green t-posts blend into the natural landscape and were very difficult spot. The operator would <br /> benefit from painting the t-post a bright color or perhaps adding a tall stick of white PVC to make the permit <br /> boundary easier to delineate at a distance. <br /> This site is used to maintain approximately 15 miles of dirt road. No crushing or screening of material is <br /> required for it to be used. No equipment, fuel or structures were observed. It was indicated by Mr. Guinta that <br /> the last mining occurred a few days ago. <br /> Per the mining plan, mining will occur in benches approximately 30'W x 15'H. To date mining has not <br /> progressed enough for the use of benches. <br /> The topsoil pile is seeded and stable. Pocketing has been used well and there is little to no evidence of <br /> erosion. The entire site has been stripped of topsoil. Along the northeastern slopes, natural vegetation has <br /> volunteered. The site is stable with no erosion and no weeds were observed. <br /> Several piles of sediment pond/culvert clean out material was observed. This material may prove beneficial for <br /> reclamation given its high quality of nutrients and fine texture as compared to the native material of this site. <br /> In order to import material the operator must provide the office with notice per Rule 3.1.5 (9). "The notice <br /> shall include but is not limited to: a narrative that describes the approximate location of the proposed activity; <br /> the approximate volume of inert material to be backfilled; a signed affidavit certifying that the material is <br /> clean and inert, as defined in Rule 1.1(20); the approximate dates the proposed activity will commence and <br /> end, however, such dates shall not be an enforceable condition; an explanation of how the backfilled site will <br /> result in a post-mining configuration that is compatible with the approved post-mining land use; and a general <br /> engineering plan stat how the material will be place and stabilized in a manner to avoid unacceptable settling <br /> and voids." Please submit this notice in the form of a technical revision. <br /> A cement wash out area was also observed. The operator is reminded that per Rule 1.1(20) concrete must be <br /> in a hardened state for at least 60 days prior to burial and notice given per Rule 3.1.5(9). <br /> Based on discussions with the operator the Division recommends they file for intermittent status. Active status <br /> requires mining annually more than 180 days which this operation does not do. Intermittent status requires <br /> that a site be active annually however does not operate more than 180 days a year. If the mine ceases <br /> production for more than a year it shall go into temporary cessation. Mining activities include not only <br /> excavation but the moving of stockpiled materials as well. <br /> Staff digitized the permit boundary depicted in the 2015 annual report using google earth images which <br />
