ta- <br />Holcim <br />November 21, 2008 <br />Mr. Berhan Keffelew <br />Colorado Department of Natural Resources <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Holcim (US) Inc. Phone 719 784 6325 <br />3500 Highway 120 Fax 719 784 3470 <br />Florence, CO 81226 www.hoicim.com/us <br />Denver, CO 80203 / <br />Re: Proposed Groundwater Monitoring Plan DRMS Permit M-1977-34A' <br />Dear Mr. Keffelew, <br />The purpose of this groundwater monitoring plan (GMP) is to fulfill the requirements of <br />Technical Revision #6 (TR-06) to the Division of Mining, Reclamation and Safety Permit M- <br />1977-344. This permit is for the Holcim (US) Portland Plant quarry located adjacent to the <br />cement plant in Florence, Colorado. <br />The quarry is located on the north side of the Arkansas River. Groundwater in the area flows in <br />a generally southerly direction toward the river. See Figure 2 attached from the March 2008 <br />Groundwater Monitoring Report. <br />Holcim proposes annual sampling of the following monitoring wells: <br />• MW 12 - Background well located in the north end of the quarry. <br />• MW7 - Compliance well located in the southwest side of the quarry. <br />• MW 13' -Compliance well to be located in the south side of the quarry inclose proximity <br />to Piezometer P-3 near the entrance to the quarry. <br />Note, this well is proposed to be drilled in April 2009 and will be a 2" ID Schedule 40 PVC well <br />approximately 50 feet in depth. <br />In addition, Holcim will continue monitoring water level in wells P-2, P-3, MW9, and MW11. <br />Holcim proposes abandoning the following wells: <br />• MW6 -this well is located next to MW12 and is thus redundant and unnecessary. <br />• MW8 - this well is located in an area that will be reclaimed, i.e. buried, in 2009. <br />• MW10 -this well is too shallow to provide useful data. <br />The wells will be abandoned in accordance with Colorado rules and regulations governing well <br />abandonment.
