—� available, a compacted earth barrier will be installed over the perimeter drain such <br /> • <br /> that the drain is hydraulically connected to the surrounding alluvial aquifer and <br /> LOVELAND hydraulically separated from the interior of the gravel pit. Once the gravel pit <br /> perimeter is entirely sealed,the perimeter drain will serve to route groundwater <br /> READY-MIX around the barrier by maintaining a high permeability adjacent to the compacted <br /> backfill." <br /> CONCRETEIn addition to the revision to the general backfill detail, the following minor revisions <br /> have also been made: <br /> PO BOX 299 1. Exhibit F has been revised to show the relocation of this perimeter drain to <br /> LOVELAND,CO 80539 accommodate the Partial Release of 2.5 acres in the SW corner of the site in <br /> approved AR-1. <br /> OFFICE 970.667.2680 2. Exhibits C and F have been revised to show the relocation of the 6 foot <br /> FAX 970.667.0092 perimeter berm and the secondary access road at the SW corner to <br /> accommodate the Partial Release of 2.5 acres in AR-1. Due to the location of <br /> the partial release and the small and limited effect it has on mining,the Table <br /> in Exhibit C with estimated mining quantities has not been changed. <br /> 3. Exhibit F has been revised to show that some of the perimeter berms will <br /> remain as part of final reclamation as determined through the Larimer County <br /> land use process and supported by the approved Larimer County Site Plan. <br /> These berms will be established with dryland pasture grass, along with some <br /> trees and shrubs, and will continue to serve as a buffer between the adjacent <br /> landowners and the reclaimed pasture use. <br /> 4. Exhibits C and F have been revised to show the final location and configuration <br /> of stormwater infiltration ponds and detention ponds as approved through the <br /> Larimer County land use process. <br /> If you have any questions regarding this Technical Revision or require additional <br /> information, please advise. <br /> Thank you, <br /> Stephanie Fancher- glish <br /> Loveland Ready-Mix Concrete, Inc. <br /> cc: file <br /> attachments <br />
