ASPHALT <br /> kL <br /> SPECIALTIES CO. <br /> Turnpike Mining Resource-Permit No. M-2004-009 June 21,2019 <br /> Technical Revision No. 5 (TR-05) Page 3 <br /> CINQUE FEDERAL 8-31 Well: Located at the south end of Cell 2B, the well has been P&A. <br /> The 75-foot mining setback and 200-foot backfill radii have been removed as they are not <br /> currently applicable. The well symbol has been updated to reflect the current P&A status. <br /> ASPHALT AND CONCRETE RECYCLING AREA: Previously located in the northwest <br /> corner of Cell 2A on the South Half of Permit Area(Sheet 2 of 2),this area has been removed. <br /> A screenshot of the Colorado Oil and Gas Conservation Commission (COGCC) Geographic <br /> Information System (GIS) online interactive map database (accessed on May 28, 2019) showing the <br /> status for the nine (9) wells located on the property is provided in Attachment A. A copy of the <br /> revised Exhibit C-2-Mine Plan Maps is provided in Attachment B. <br /> 6.4.4. EXHIBIT D-MINING PLAN <br /> (e) Approximate Mining Timetable <br /> Currently, mine operations are transitioning from backfilling Cell 2B to mining/re-mining Cell 3 (the <br /> 2013 floods re-deposited mineable material back into the cell). Mining operations will continue <br /> move to the west in the future (i.e., after Cell 3 is mined, operations will move to Cell 4, then Cell 5, <br /> and then Cell 6). An approximate mining timetable is given in Table 6.4.4-2. However, as aggregate <br /> mining and processing is entirely dependent on market conditions, the mining timetable is an <br /> estimated schedule. <br /> Table 6.4.4-2: Mining Timetable <br /> Mining Cell Size of Mining Cell Approximate Time Until Complete <br /> Cell 2A 22 acres 5 Years(Majority of Cell Mined) <br /> Cell 213 29 acres Complete <br /> Cell 2C 10.5 acres 5 Years(Majority of Cell Mined) <br /> Cell 3 20 acres 1 year(Partially Mined) <br /> Cell 4 13 acres 2-3 Years <br /> Cell 5 9 acres 3-4 Years <br /> Cell 6 1.5 acres 4-5 Years <br /> Total 105 acres 4-5 Years <br /> Note: <br /> Cell 1 (85 acres)has been released from the permit as the Erie Water Treatment Facility. <br /> Attachments: <br /> Attachment A COGCC GIS Online Map Screenshot <br /> Attachment B Exhibit C-2-Mine Plan Maps <br /> cc: <br /> ASCI File <br />
