Parks&Open Space Department <br /> Adams County Regional Park <br /> 9755 Henderson Road <br /> AD"S COUNTY Brighton,CO 80601 <br /> PHONE 303.637.8000 <br /> FAx 303.637.8015 <br /> www.adcogov.org <br /> April 7, 2016 <br /> Division of Reclamation, Mining and Safety <br /> 1313 Sherman St., Room 215 <br /> Denver, CO 80203 <br /> Re: 2014 112c Annual Report—Nyholt Pit(aka Mann), Permit#M-1982-147 <br /> Dear DRMS: <br /> The Nyholt(aka Mann)Pit was mined for several years by Mobile Pre-Mix/Lafarge. Lafarge ceased mining <br /> operations in December of 2009. Adams County Parks accepted succession of operator in December of 2009 and <br /> will continue to control noxious weeds at the site, establish native grasses and complete required site reclamation. <br /> We have also been working to haul off approximately 15,000 tons of already processed materials from the site <br /> leaving approximately 40,000 tons of processed material. <br /> On September 12 and 13 of 2013 the mining site experienced fairly extensive sheet flooding which caused erosion <br /> damage to the banks of the reservoirs. Although the liners weren't significantly damaged, repairs to the <br /> embankments are currently being finalized. During the engineering process it was determined that armoring affected <br /> areas would be desirable. To this end, Adams County submitted plans to the Division through a Technical Revision <br /> (TR)process in October of 2014. The TR was accepted by the DRMS on November 5, 2014 and armoring and site <br /> restoration was competed in the spring of 2015. <br /> A modified 30-day liner leak test for the State of Colorado (Division of Water Resources) for Lake #1 was also <br /> completed. The Stat approved the leak test and certified the lake on May 26,2015. All of the necessary repair work <br /> is being reported in this 2015 annual report(attached).Additional information can be provided upon request. <br /> Enclosed is a map illustrating site work,weed mitigation and other work that was completed in the 2015 calendar <br /> year and anticipated in 2016.Additionally, a check is enclosed in the amount of$791.00 (Check No. 691333) <br /> intended to cover the annual fee for the 2015 reporting period. <br /> Sincerely, <br /> Nathan Mosley, Director <br /> Adams County Parks and Open Space Department <br /> Enclosures: (3) 112c Report/ Site Map/Check No. 691333 <br /> BOARD OF COUNTY COMMISSIONERS <br /> Eva J.Henry Charles"Chaz"Tedesco Erik Hansen Steve O'Dorisio Jan Pawlowski <br /> DISTRICT I DISTRICT 2 DISTRICT 3 DISTRICT 4 DISTRICT 5 <br />
