Rifle Gravel Pit#1 May 2023 <br /> 5.2.5 Schedule of Operations <br /> Hours of operation shall be Monday through Saturday 7 a.m. to 7 p.m. (Mountain Daylight <br /> Time, MDT)with no operations on Sunday. During winter months from 11/1 to 3/21 hours of <br /> operation shall be Monday through Saturday 7 a.m. to 5 p.m. (Mountain Standard Time, <br /> MST). <br /> Excavation and processing would occur approximately 8 months of the year depending on <br /> the occurrence of freezing temperatures (roughly April— November)and material sales <br /> would occur year-round. Total recoverable volume is estimated at approximately 292,810 <br /> CY of aggregate, which is expected to support operations for between three and five years. <br /> The Rifle Gravel Pit will operate from 7 am to 7 pm Monday through Friday, and on <br /> Saturdays as needed. Approximately 3 to 5 employees will be on site during this phase of <br /> the mining operations. No nighttime activities are anticipated. Occasional equipment repair, <br /> or maintenance may be conducted at night, but lighting will be kept to a minimum and <br /> directed inward; the site will not have ambient lighting. <br /> 5.2.6 Existing or Proposed Roads <br /> No existing nor proposed roads will be used for the mining operation on-site. Scott will <br /> designate temporary travelways on the operating surface of the mine on a flexible and as- <br /> needed basis, to account for the changing layout of the mine as excavation proceeds. These <br /> travelways would consist of the native gravel materials exposed after removal of the <br /> overburden, supplemented with a surface of roadbase approximately 3"thick to control mud. <br /> The travelways on the working surface of the mine would not be permanently compacted, <br /> surfaced, or otherwise constructed. A portion of CR-346 (1-70 Frontage Road)will be <br /> improved as described in the CDOT Access Permit(Attachment B) and used for access to <br /> and from the site. <br /> 5.2.7 Drainage and Runoff Conveyance <br /> Previous sections of this application describe the water handling activities for this proposed <br /> project. <br /> 5.2.8 Reclamation (Phase 4 [P4]) <br /> This section describes the earthmoving and reclamation activities and size of the areas to <br /> be worked during Phase 4. <br /> The six-foot wide fringe of 5:1 slope that was constructed at the inner edge of the perimeter <br /> berm will be planted with wetland reclamation species. The intention is for the six-foot wide <br /> fringe to be nearly inundated during high-water periods as the water table rises, and then to <br /> be progressively exposed as the water table drops during the growing season. The <br /> remainder of the pit slope to the bottom of the pond will not exceed 3HA V slopes. Note that <br /> this reclamation effort follows Garfield County LUC standards (LUC Section 7-1002.11-1). <br /> Formal wetland mitigation per USACE standards is not required, as no impacts to wetlands <br /> are proposed. <br /> See Section 6 for additional information regarding reclamation of the property. <br /> 5.3 Mining Timetable <br /> 30 <br />
