UPDATED MINING PLAN <br />11/3/83 <br />The La Plata County Gravel Pit-Ignacio is an existing open pit <br />gravel mine. A gravel crusher has previously been used at this site <br />on many occassions and will be used in the future. La Plata County <br />does not own a gravel crusher. Therefore, contracts are executed with <br />crusher operators to move into the mine and crush the required quantities <br />of gravel under the supervision of La Plata County. Pfining of this pit <br />will be conducted by first stripping any overburden material ~:lear of <br />the gravel and stockpiling the overburden for future reclamation use. <br />This stripping procedure will be done with a crawler type tra~:tor that <br />is equipped with a dozer blade. Material uncovered will then be fed <br />into the crusher with a front end loader. Processed gravel wi:Ll then be <br />stockpiled at the site for future use. It will be hauled to the various <br />job sites by 56,000 GVW tandem dump trucks. <br />La Plata County intends to commence mining operations at once and <br />continue for an undetermined number of years. Mining will generally be <br />proceeding in a northerly and northeasterly direction. Future mining will <br />not be conducted in southerly direction since the dedicated easement <br />access road cannot be disturbed. It appears possible to extreict approx- <br />imately seven (7) feet of additional gravel vertically in the existing <br />mined area without encountering excessive amounts of shale. <br />
