CIG currently owns, operates, and maintains <br />the 24B-16" CF&I - S. Pueblo Loop high pressure natural gas transmission pipeline which <br />crosses the subject area. The Maximum Allowable Operating Pressure (MAOP) is 400 psig for <br />this pipeline. <br />CIG's referenced pipeline traverses this area, however, if the following conditions are observed <br />with regard to the pipeline, CIG has no objection to the mining operation. <br />The mining operations will not encroach within fifty (501 feet of either side of CIG's <br />pipeline facility. A minimum slope of 4:1 will be maintained as a back slope to the <br />existing right of way easement from this time forward of the current operations. <br />2. The existing cover over the pipeline must not be lowered. <br />3. Haul roads or equipment crossings over CIG's right of way easement may require an <br />increase in the amount of cover over the pipeline. Should a road base be installed that <br />would encroach on this cover, then a stress analysis would need to be performed based <br />or actual equipment loading information. Engineering would prefer to have actual road <br />cross-sections, at the pipeline crossings, in order to perform the load analysis. <br />4. No blasting shall be allowed unless prior approvals are obtained from CIG. <br />5. CIG will not permit any permanent structures to be constructed within the pipeline <br />easement area without first obtaining written permission. <br />6. Contact the Utility Notification Center of Colorado at 1-800-922-1987 at least two <br />working days prior to the commencement of any mining activities on the property and <br />such construction shall be made only when a representative of CIG is present at the <br />time of construction. <br />Colorado Interstate Cos Company <br />ABUBSl0/ARYOF rNE COAB rAL LORPOM r10N <br />P 0 BOX 1081' • LOLGRAUO SPRINGS C0809Id • ll'Ya;3-2700 <br />
