(Page 2) MINE ID # OR PROSPECTING ID #: M-i 4»-non INSPECTION DATE: ~/4in~ INSPECTOR=S INITIALS: TAB 1. A site inspection of the Greeley Pit (35th Avenue Pit) was conducted as part of the Division`s 4-year inspection program. The pit is located t/z mile northwest of Greeley immediately south of the Cache La Poudre River. Present during the inspection was Kevin Moore and Mary Harnett of Lafarge West, Inc. 2. The 35th Avenue Pit is permitted for a total of 369 acres. The mine plan specifies de-watering and dry mining methods. The pit will be reclaimed to three (3) unlined ponds with a total water surface area of 245 acres. The pond shorelines will be irregular and graded to a maximum steepness of 3:1. Surrounding areas will be topsoiled, then revegetated with a grass mix and a variety of trees and shrubs. The operator has posted a financial warranty of $78,727 in the form of a corporate surety. The post-mining land use is recreation. 3. An entrance sign and affected land boundary markers were posted as required by Rule 3.1.12. 4. The 35"' Avenue Pit is an active operation with excavation currently occurring in the Phase 3,4,9,10,&11 areas. The operator is de-watering and dry mining as specified in the mine plan. Disturbances noted at the time of inspection were found to be within the permit area, in compliance with the mine plan, and are as follows: A) A reclaimed pond of approximately 116.5 acres in the Phase 1812 areas. Shorelines have been adequately graded to finish contours and topsoiled. Shoreline and surrounding slopes have not been revegetated. There is a substantial number of tamarix shrubs around the pond shoreline. The Division considers the presence of tamarix to be a problem that will require corrective actions as tamarix is considered to be a noxious weed in Colorado. Please see page 4 for corrective actions. B) A 27.5 acre pond in the Phase 3,4,5 area. Shorelines appear to be adequately graded to a 3:1 configuration. C) A 5.5 acre pond in the Phase 5 area. D) A 10 acre dry excavation of approximately 10' depth in the Phase 8 area. This inspector estimates 2640 linear feet of pit wall at a 1:1 slope, and 2200 cubic yards of finish grading to achieve the desired 3:1 slopes. E) A 32 acre dry excavation of approximately 32' depth in the Phase 3,4,9,10,8c11 areas. This inspector estimates 5000 linear feet of pit wall at a 1:1 slope, and 46,296 cubic yards of finish grading to achieve the desired 3:1 slopes. F) An asphalt plant, a large concrete plant, a large paved surface, an office and scales, and shop building. These structures and associated concrete foundations will need to be removed during final reclamation. There was also 40,000 tons of stockpiled broken asphalt, and 64,500 cubic yards of stockpiled broken concrete. The broken asphalt and broken concrete will need to be either need to be processed into finished product, backfiiled into one of the pit excavations, or removed offsite during final reclamation. 5. Ms. Harnett indicated that Lafarge West, Inc. has an approved temporary substitute supply plan from the Office of the State Engineer (OSE) for exposed groundwater at the site. 6. This inspector conveyed to the operator that one of the purposes of the inspection was to evaluate existing disturbances and verify the adequacy the $78,727 financial warranty. As a part of this process, the operator volunteered to provide demolition costs for the plant site, concrete plant, asphalt plant, paved surfaces, shop building, broken asphalt stockpile, and broken concrete stockpile as these features are extensive. This inspector emphasized that the demolition costs will need to include removal of fuel tanks, paved or asphalt surfaces, buildings, concrete pads or foundations, truck scales, water pumps, and any other features not specified in the reclamation plan. The operator also volunteered to provide an accurate measurement of the following items: a) the number of linear feet and height of exposed pit walls, b) volume of stockpiled topsoil, c) volume of broken concrete, and d) volume of broken asphalt. Ms. Harnett estimated this information would be submitted to the Division by before March 1, 2003.
