Havengar <br />From: <br />Clint Brown, P.E. <br />Nate Bolles, P.G. <br />Company: <br />Lazy H Inc <br />Date: <br />March 20, 2015 <br />EA No.: <br />110545 <br />Re: <br />Exhibit C — Mining Plan <br />Applicant: Lazy H Inc <br />Cc: <br />Rod Baumgartner, Henrylyn Irrigation District <br />A) Mining activities are anticipated to begin by April 3, 2015 and continue for approximately <br />seven weeks. The anticipated end date of mining is expected to end on or around June 1, <br />2015. <br />B) Approximately 3 inches of topsoil will be removed from the site and stockpiled for reuse <br />during reclamation. The actual depth of topsoil removed will depend on the volume present <br />during excavation. <br />C) Besides topsoil that will be reused during reclamation, no overburden or waste rock will <br />be produced. The material is being mined for use as miscellaneous fill. <br />D) Between approximately five and ten feet of soil will be mined, depending on the varying <br />thickness of the sand layer. <br />E) The site will be accessed by low impact mining equipment, which consists of pickup trucks, <br />one excavator, and three -axle dump trucks. A proposed access road will extend from the <br />southwest corner of the mine site to Hudson Mile Road. Mined material will be transported <br />offsite to other locations requiring fill. A portable toilet will be provided onsite. No other <br />land improvements or structures will be constructed. <br />F) Excavation will be limited to the areas shown in Exhibit E -1, Mining Plan (13.1 acres). <br />Mining will consist of removing shallow sand and surface grading. A new access road will <br />consist of approximately 0.4 acres. <br />G) A proposed access road will be constructed to access the south side of the site using a <br />grader to create a flat road surface approximately 15 feet in width (Exhibit E -1). <br />H) Water consumption for mining and processing of the material will be minimal and will <br />consist of dust suppression for haul roads when necessary. Total annual water consumption <br />is anticipated to be less than 0.25 acre -feet. Lazy H Inc has secured water from the Denver - <br />Hudson Canal, which is owned by Henrylyn Irrigation District (lessee). There will not be <br />any onsite material processing. Thus, mining operations will not require any additional <br />water sources. The proposed operations will not require any surface water diversions, pit <br />dewatering, and/or impoundments. Storm water will be managed by onsite ponding and <br />evaporation. <br />Exhibit C.docx I Engineering A nalytics, Inc. <br />
