The thickness of overburden to be removed during gravel extraction is believed to be <br /> approximately 12 inches in depth. Soils and waste rock unsuitable for construction materials will <br /> be separated from the gravels and may be stockpiled at the site. These soil stockpiles will be <br /> utilized for excavation backfill and site reclamation. <br /> (b) Reclaimed slope gradient: <br /> The extraction site currently exists as a roughly 2%slope. During reclamation, and as required <br /> by 2 CCR 407-4 Rule 3.1.5(1), Applicant will grade the site to conform with the natural gradient <br /> and contours of the slope and the surrounding area in order to ensure that the site complies with <br /> the intended post-reclamation use as rangeland. Applicant will mine and grade the site so as to <br /> leave the graded area at no more than a 3H:1V on the sideslopes and 1-2% slope on pit bottom. <br /> Applicant will follow stormwater management best practices published by state and local <br /> authorities. The Applicant anticipates that any stormwater will collect at the bottom of the <br /> extraction pit and will be absorbed into the soil. Site grading will be developed so that <br /> concentrated drainage that could result in score does not occur. <br /> (c) Revegetation Measures to Reclaim the Site <br /> Applicant has consulted with Tony Waldron, former supervisor of the DRMS Minerals Program, <br /> and has reviewed the Weld County Weed Division's recommendations and specifications for <br /> reseeding disturbed ground.' <br /> (i)Any topsoil previously removed will be replaced as plant growth medium. <br /> Applicant expects 12 inches of topsoil will be removed, as practicable. All topsoil will be <br /> evenly distributed over the areas from which it was removed in thicknesses equal to the <br /> original topsoil depths found at the site. Prior to removing topsoil, Applicant shall sample <br /> and analyze available soils sufficiently to establish quantity and quality in order to ensure <br /> consistency during reclamation. <br /> (ii) The site will be seeded upon completion of the permitted mining activities. <br /> The seedbed will be prepared to eliminate compacted conditions by discing or shallow <br /> ripping followed by harrowing to level and firm up seed bed. Seeding will occur utilizing <br /> a grass seed drill or by broadcasting. If broadcasting is utilized, the seed rate will be <br /> doubled and the seed will be incorporated by harrowing following seed application. Soil <br /> amendments will only be utilized if testing indicates deficiencies but it is anticipated that <br /> none will be necessary given the short amount of time the topsoil will be stored.. If <br /> deemed necessary based upon soil tests, the type, application rate, and soil incorporation <br /> methods of fertilizer application shall be as follows: <br /> (iii) Trees and shrubs are not present on the site. For areas north of County Road <br /> 68, the Weld County Weed Division recommends that the following live seed mixture be <br /> disbursed: <br /> ' https://wNvw.weldgov.com!det)artments/public works/vveed management/controlling weeds/reseeding <br /> Oak Creek Consulting and Production Services,LLC Page 2of 5 <br /> Construction Materials Limited Impact(I I0(c))Operation Reclamation Permit Application Form <br />
