• Additional Sheet • i Snyder Quarry 1995-1996 Annual Report May 27, 1996 Included with this report is the annual report map. This map shows the status of various features within the operation. No map is provided of the road corridor as no changes occurred there in the last year. The only mining was a small piece on the top of the North Wall. This rounded the crest of the wall to make it less objectionable. All other mining was within the main pit area and mainly involved sales from extensive stockpiled material. In the spring of 1995, the heavy precipitation caused some damage to the eastern side of the operation. One storm was so large the drainage extending down and just outside the east boundary of the permit flooded. This flood even filled the water storage pond, which was essentially empty at the time. This pond has a capacity of nearly 1 million gallons. The pond overflowed and the outflow continued down the access road and into the sediment ponds. The sediment ponds are a two staged system. The second stage had never contained water before. Yet this flood was so great it not only filled both ponds but washed out the dam, the culvert, and the emergency overflow. The actual amount of rain received is unknown. All damages were repaired, the dam replaced and made even stronger, and the culvert system modified somewhat. No other damages occurred along the road other than some road cut erosion that caused rocks and a few trees to fall on the road. This was cleaned and repairs effected. The only additional reclamation done at this site was Enhanced Reclamation, the publicly funded program to mitigate visual impact. Alfalfa was planted on the Visual Betm to increase the vegetation density. This planting was largely unsuccessful due to the already high density of the vegetation. There is simply too much existing growth to allow for any more growth, even though germination and growth conditions for alfalfa in 1995 were near ideal. The small area labeled "Violation Reclamation" is the area where accidental rock spillage damaged the existing vegetation outside the permit boundary. This repair is progressing very well and today there is little evidence remaining of the damages. Tree seedlings planted on this hillside are doing well and recovery of the natural vegetation is excellent. In early May 1996, trees were planted on the visual berm. Fifty, two to three foot tall Pinon Pine and Juniper trees were planted along with about 100 seedlings. This planting, if successful, will help to blend the vegetation of the Visual Berm into the forested land below, south, and north of the berm, when viewed from the southeast. Competition from existing vegetation is expected to be intense, but other trees, mainly Juniper, have been successful. It is expected that mining during the next year will primazily concentrate on the West Ridge, possibly bringing that to completion. Thus expansion of the existing affected land is not expected in the next year. Annual Report Snyder Quarry 95/96 M-77-210 Page 1
