Water District 5, Weld County SWSP Plan Id: 3609 Approval Period: January 1, 2020 through December 31, 2020 Contact phone number for Mr. Andy Rodriguez: 303-833-1416 Dear Mr. Rodriguez: We have reviewed your letter dated September 27, 2019, requesting renewal of the above-referenced substitute water supply plan to cover depletions at the Shores Sand Et Gravel mine, operated by Bestway Concrete Et Aggregate ("Applicant"). The required fee of $257.00 for the renewal of this substitute water supply plan has been submitted (receipt no. 3694050). The original plan was approved on May 21, 2001 and was most recently approved on March 14, 2019 for operations through December 31, 2019. Plan Operation This plan seeks to replace depletions resulting from mining operations at the Shores gravel pit. The site contains five slurry walled areas, designated pits A through E, as shown on the attached Figure 1. Together these five cells are planned to eventually be connected via pipelines, by others, and become Shores Lake (WDID 0503900) as adjudicated in case no. 2000CW83. Pits A, B, C, D and E were initially dewatered and dry mined. A slurry wall was constructed around pits A and B and lining for these cells was approved on January 11, 2007. A slurry wall was constructed around pit C and was approved on December 7, 2009. A slurry wall was constructed around pit D and was approved on October 8, 2013. A slurry wall was constructed around pit E and was approved on June 23, 2017. Mining has stopped in Pits A and E. The depletions that result from mining operations at the Shores pit are evaporation from a silt pond and open surface water surrounding Pond E, concrete batching, dust suppression and dewatering lagged depletions. The proposed replacement sources are 1.3 shares of the Rural Ditch and water stored in Pond E during free river. In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado Division of Reclamation, Mining, and Safety ("DRMS"), all sand and gravel mining operators must comply with the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for the protection of water resources. The April 30, 2010 letter from DRMS requires that you provide information to DRMS to demonstrate you can replace long term injurious stream depletions that result from mining related exposure of groundwater.
