PERMIT#:M-2002-004 <br /> INSPECTOR'S INITIALS: TOD <br /> INSPECTION DATE:November 13,2015 <br /> OBSERVATIONS <br /> This routine monitoring inspection was conducted by Tyler O'Donnell and Wally Erickson of the Division of <br /> Reclamation, Mining and Safety (Division). GCC Rio Grande, Inc., the Operator, was represented by Nancy <br /> Garnett, Edwin Olivares, and Damian Flores during the inspection. The Colorado State Land Board, the <br /> Landowner, was represented by Phil Courtney during the inspection. <br /> The Pueblo Cement Plant and Limestone Quarry is located in Pueblo County approximately 8 miles south- <br /> southeast of Pueblo,Colorado. The Pueblo Cement Plant and Limestone Quarry is a 2500-acre 112c Construction <br /> Materials Reclamation Permit. The permit was issued in August 2003. The primary commodity mined at the site <br /> is limestone. The approved post-mining land use for the quarry area is rangeland and industrial/commercial for <br /> the plant site area. The mine site was surrounded by the following land uses: industrial/commercial and <br /> rangeland. <br /> During the inspection, the sky was clear and the ground was dry. The mining operation was active during the <br /> inspection. The Operator was processing material that was stockpiled within the raw feed material dome. At the <br /> present time it appears that the mining operation has affected approximately 160 acres throughout the life of mine. <br /> The Operator has been conducting adequate concurrent reclamation. The majority of the area previously affected <br /> by the mining operation, has been graded, topsoil had been spread, and revegetation efforts vary throughout the <br /> final graded areas. With concurrent reclamation the current active footprint of the mining operation was <br /> approximately 40 acres. The mining operation appears to be progressing from the northwest to the southeast. It <br /> appears that the operation has affected land in phases Y1 through Y5 and Phase 1. <br /> Acid and Toxic Materials: <br /> There appeared to be an adequate secondary containment structure built around the petroleum storage tanks(photo <br /> 1). The secondary containment structure appeared to have enough volume to contain all contents of the fuel tanks <br /> and various containers, plus an additional 10% or more capacity beyond the total capacity of stored petroleum <br /> products. <br /> Backfilling and Grading_ <br /> It appears that approximately 75 acres located along the western portion of phases Y1 through Y5 had been <br /> backfilled and graded. The slopes were graded to 4H:1 V or flatter and appeared to be structurally stable. <br /> Approximately 16 acres located in the southwest corner of phase Y5 had been recently graded to 4H:1 V or flatter <br /> (photos 2 and 3). <br /> Financial Warranty: <br /> The current amount of financial warranty the Operator has on deposit with the State is $1,885,000.00. <br /> The reclamation cost estimate for this permit was updated with this inspection. It was determined that the current <br /> financial warranty amount is adequate to conduct the approved reclamation plan. <br /> Fish and Wildlife: <br /> During the inspection the Division suggested that the Operator could use large pieces of waste rock to construct <br /> rock piles to provide habitat for small mammals. The Operator embraced the concept of creating addtional habitat <br /> for wildlife. <br /> Hydrologic Balance: <br /> The site was dry,no exposed groundwater was observed during the inspection. During the inspection the Operator <br /> attempted to collect a groundwater sample from MW-05. During the inspection MW-05 was dry. The Operator <br /> is required to attempt to collect semiannual water quality samples from MW-05,and submit the monitoring results <br /> Page 2 of 7 <br />
