Recommendation for Approval of Application Over Objection; Regular 112 Construction Materials Amendment Application Ready Mixed Concrete Company Bromley Lakes, Permit No. M-1987-049 ? ,/ October 22, 2009 Introduction This document is intended to provide a basis for the Division's recommendation for approval of the application over the objection raised to the Bromley Lakes Permit Amendment Application, File No. M- 1987-049. This application was submitted by Ready Mixed Concrete Company DBA Ready Mixed Aggregates, Inc. on March 6th, 2009. The application was found complete and considered filed with the Division on March 19th, 2009. The site is located approximately 2 miles south of Brighton, Colorado in Adams County. The center of the area where the majority of mining will occur is in Sections 12, 13, 14 and 24 of Township 1 South, Range 67 West of the 6t principle meridian. The current approved permit area for this site is 172.5 acres, the operator wishes to add an additional 115.3 acres. If approved, the total permit acreage for this site will be 287.8 acres. The amendment to this permit accomplishes three objectives for Ready Mixed Concrete Company. One, they will incorporate Ready Mixed Pit No. 1 (M-1985-017) into the Bromley Lakes permit. Two, they will modify the proposed end land use of a portion of the existing permitted area from open lakes and wildlife habitat to a sealed water storage reservoir at the request of the current landowner. Three, the operator will add 77 un- mined acres to the permit area located near the southeast portion of the current permit boundary. The majority of the current acreage within the Bromley Lakes site and Ready Mixed Pit No. 1 has been mined. The operator proposes to create a sealed water storage reservoir out of the combined Bromley Lakes Cell No. 3 excavation and the pit excavation at Ready Mixed Pit. No. 1. The reservoir will be surrounded by a slurry wall. North of Cell 3, there are four other pit excavations in place; some of which are being used as settling ponds. The operator proposes to backfill these pit excavations and create wetland and upland areas. In the future, the operator intends to mine the remainder of the current permit area for the Bromley Lakes site including the processing area, and the proposed 77 acre expansion area. To accomplish the post mine configuration of the affected land, the operator will have to re-locate the McCann Ditch, owned and operated by the McCann Ditch and Reservoir Company. The current processing area located in the Bromley Lakes site will be mined to create an open water pond. For the proposed 77 acre expansion area, the operator will mine and reclaim concurrently, leaving a relatively flat upland area east of the sealed water storage reservoir.
