i <br /> <br />Explanation of Request <br />Aggregate Industries (AI) is completing mining and reclamation on a 287.4-acre <br />property permitted under the name of "Brighton Mine" with an existing case <br />number of PRJ2007-00022. The operation is located along the east side of Riverdale <br />Road roughly where 144th Avenue would bi-sect the permit area. Reclamation of the <br />property will leave three lakes on the property. The southern two lakes will be <br />utilized in the future as sealed water storage reservoirs for the City of Thornton, <br />and the third north lake will be an unsealed lake area to be conveyed to Adams <br />County for open space uses. <br />Approximately %2 of this area was permitted originally for mining and reclamation <br />in 1977. Mining didn't commence until 1982, and this original area was mined <br />intermittently until Al acquired the property. After Al acquired the original <br />-- 'property,-and other-adjacent: properties, AI gx anded and amended the State's <br />Reclamation Permit (#M-77-438) and obtained the County's approval^in`Cointy - -- <br />Case No. PRJ2000-00026 of revised and expanded mining and reclamation plans. <br />PRJ2000-00026 had a mining expiration date of 09/18/07 and a reclamation <br />expiration date of 01/01/09. Then, in response to the economic slowdown, Al <br />received an extension of the mining expiration date to 12/31/09 and the reclamation <br />date to 12/31/10 in Case No. PRJ2007-00022.Since approval of PRJ2007-00022, the <br />applicant has been working diligently to complete both mining and reclamation, but <br />the continuing slowdown in the economy the last few years, has continued to slow <br />the rate of mining. <br />Al is therefore requesting a 9-month extension of the mining completion date to <br />09/30110. No extension is requested on the existing 12/31/10 reclamation completion <br />date. The hours of operation will continue as the presently allowed of 6:00 am to <br />7:00 pm. Truck traffic will continue to be an estimated maximum of 500 truck <br />trips/day, but because of the economic slowdown, mining and hauling will continue <br />to be intermittent. Except for local deliveries to the south, truck traffic will continue <br />to be required to utilize Riverdale Road north to SH7. All other standards and <br />conditions of PRJ2007-00022 will still be followed, and Al would request a favorable <br />recommendation from the Planning Staff and a_favorable decision by the: Planning <br />Commission of this Conditional Use Minor Amendment request. <br />Accompanying this Explanation are of an Index Map showing the property's <br />location, the Mining and Explanation Plan Narratives, and reduced copies of the <br />Mining and Reclamation Plan Maps. <br />INFORMATION PROVIDED <br />BY APPLICANT
