(Page 2) MINE ID # OR PROSPECTING ID # M-2001-051 INSPECTION DATE 03/07/06 INSPECTOR'S INITIALS ESC This was an inspection of the North Taft Hill Expansion Site, File No. M-2001-051 conducted by Erica Crosby of the Colorado Division of Minerals & Geology. Eric Reckentine and Gary Knox were present during the inspection. A 112 Construction Materials permit was issued for the North Taft Hill Expansion Site on August 1, 2002. The permit area is 51.18 acres. The poatmining land use is wildlife habitat. The Division holds a bond in the amount of $470,124.00. The southern edge of Phase I has been mined. A small section of the pit has been reclaimed into a groundwater-exposed pond. Slopes of the pond were seeded in the fall of 2005 and will be reseeded this spring. Mining of Phase II is within 50 feet of the overhead power lines. Mining has temporarily ceased at this site and has moved to the adjacent Home Office Pit (also referred to by the operator as the Seaworth site), Permit No. M-1977-439. According to the operator, mining will resume at the North Taft Hi11 Expansion site in approximately 8 years. The operator should be aware that if no mining or reclamation is scheduled to take place within 180 days or more, the operator must file a Notice of Temporary Cessation (TC) in writing to the Division. See Rule 1.13 of the Construction Materials Rules and Regulations for further detail on TC requirements. As noted above, the Home Office site is immediately south of the North Taft Hill Expansion Site. However, the berm that was to separate the two pits has been mined through creating one large pit. in addition, the North Taft Hill Expansion Site is utilizing the settling ponds and stockpiling material at the Home Office Pit. The North Taft Hill Expansion Site mine plan depicts that mining will extend directly up to the permit boundary and that settling ponds and overburden piles will be constructed on the east side of the pit. The pit will be reclaimed to a groundwater-exposed pond (separate from the Home Office proposed pond). The Division reviewed the approved mining and reclamation plan (Amendment O1 (AM-O1)) for the Home Office site. The approved plan states that there will be a 25 foot buffer from the edge of the adjacent property and maintain a 5.9 acre buffer area around the mining area (referred to as Area F on the mine plan maps dated 7/31/87). The mining of the berm will need to be addressed by the operator in the form of a revision to the Home Office Permit (see Home Office inspection report for further detail). In regards to the North Taft Hill Expansion site, mining is different than what is approved in the mining and reclamation plan with the use of the sediment control structures and overburden piles located in the adjacent Home Office Pit. Therefore, the operator will need to file a revision to the permit to reflect the change in the mine plan. Also, if the operator intends to change the reclamation plan to have one large pond connecting the North Taft Hill Expansion Site the Home Office Pit, a revision to the permit will be also be required.
