("Holcim") in accordance with C.R.S. § 37-92-308(5). The $300 fee has been submitted and given receipt no. 3653308B. This SWSP has been amended to correct errors noticed by the applicant. Plan Operation Holcim's Portland Plant manufactures Portland cement, which involves quarrying of raw materials such as limestone and silica, grinding, pyro-processing, and storing and shipping activities. The Portland Plant uses raw materials obtained from the Holcim Quarry, which operates under the Division of Reclamation, Mining and Safety (DRMS) Permit No. M-1977-344 and is the subject of this SWSP request. Depletions of groundwater within the mining boundary consist of evaporation of the exposed groundwater pits and water pumped from the pits for dust suppression. Replacement water will be supplied from a lease with the Upper Arkansas Water Conservancy District (submitted with the SWSP). The lease is a one-year lease for 150 AF of fully consumable water. Groundwater depletions from the original Portland Quarry Pond (aka "Duck Pond") are being replaced by the water right decreed in Case No. 92CW35, and are not part of this SWSP. However, the depletions from the Duck Pond will not consume the entire amount of the changed Porter Ditch right due to a decreased surface area. Therefore, the remainder of the changed Porter Ditch water right is proposed for replacement of evaporative losses for the Holcim's other ponds. In accordance with the letter dated April 30, 2010 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 ground water.
