This <br /> SWSP proposes to replace depletions which occur at the Riverbend West Pit (aka Riverbend <br /> Operations), and the Riverbend East Pit (aka Lupton Lakes Pit) as identified above. The previous <br /> SWSP was approved by our office on January 8, 2015 for the period of November 1, 2014 through <br /> October 31, 2015. The required fee of $514 ($257x2) has been submitted (receipt no. 3672434). <br /> Plan Operation <br /> This combined SWSP covers depletions at two gravel pits as shown on Figure 1 and as listed <br /> below: <br /> TABLE A - COMBINED REPLACEMENT PLAN SITES <br /> Site Name DRMS # WDID Current Well New Permit Exposed Surface <br /> Permit No. Required (acres) <br /> Riverbend West M-2000-016 0203014 55577-F No 9' <br /> Riverbend East M-2004-078 0203041 77549-F No 28 <br /> 'Area exposed under the Fort Lupton Pit, M-1985-088 but incorporated by the Riverbend West M- <br /> 2000-016 <br /> The previous combined SWSP also included lagged depletions from mining operation at Howe <br /> Pit (M1978-52, WDID 0203009). Lafarge transferred the Howe Pit to Denver Water in May 2009 and as <br /> such MMM is not covering any losses due to ground water evaporation at the Howe Pit in this SWSP. <br /> Office of the State Engineer <br /> 1313 Sherman Street, Suite 818 •Denver, CO 80203 •Phone:303-866-3581 •Fax:303-866-3589 <br /> www.water.state.co.us <br />
