will consume up to 10,000 gallons of water per day for dust suppression. Portable plants will be <br /> used onsite for rock crushing. Spray bars will be used in the crushing and screening plant to <br /> minimize dust. <br /> Aggregate processing equipment is portable. The processing equipment may move and follow <br /> active mining throughout the site. Portable mining equipment such as loaders, dozers,trucks, and <br /> excavators will be serviced onsite as needed. Upon reclamation, all portable equipment will be <br /> removed from the site. <br /> On-site roads are temporary and will change as mining progresses to the east. Support <br /> equipment will come to the site on an as-needed basis. Night mining activity may occur <br /> in the operation and portable lighting may be used within the pit from time to time. Portable <br /> toilets will be used for employees. <br /> Stormwater drainage on the disturbed areas will be directed by berms that border all disturbed <br /> areas of the site. The operation will create a depressed area. No stormwater or process water <br /> will leave the site and will be directed toward the center of the disturbed area where it will <br /> infiltrate within 72 hours. Except for the highwall, slopes will be maintained at 3H:1 V or <br /> shallower. As no stormwater will leave or is anticipated to leave the site, a CDPHE Storm Water <br /> Discharge permit is not required. <br /> 4. Topsoil and Overburden Handling <br /> Topsoil will be salvaged from the disturbed areas and placed in temporary perimeter berms <br /> surrounding the disturbed area. Piles are shown at the perimeter of the permit boundary on the <br /> Mining Map. Topsoil is expected to be approximately 3-4 inches and overburden is expected to <br /> be approximately 18-30 inches. The topsoil and overburden berms will be used for reclamation <br /> to construct 3H:1 V slopes or shallower. <br /> 5. Schedule of Operations <br /> Mining, screening, and processing will be conducted with portable equipment between February <br /> and September 2023. Mining operations will be dictated by the project schedule. Mining may <br /> take place 6 days per week for the duration of the project. <br />
