J, . ~~~y Additional Sheet Snyder Quarry 1994 Annual Report Permit #M-77-210 During the past year negotiations on the Enhanced Reclamation Plan were completed. This plan is a publicly funded plan that will address visual impact of the yuarry on surrounding areas. At about the same time this annual report is submitted an amendment to the permit will also be submitted. This amendment will modify the permit to allow for the inclusion of the Enhanced Reclamation Plan. The amendment will totally redesign the operation, remove lands previously approved for mining, and alter the reclamation processes. The Enhanced Reclamation Plan for this site, like the enhanced plan for the Queens Canyon Quarry, is primarily a vegetation overlay that will add additional tree cover and alter the seed mixtures. It also allows for staining of any remaining bench backwalls, but expects that most benches to be created in the future will have small or no backwalls, as was done on Phase 1. Revegetation Success Assessments In gathering information for this report all previous revegetation areas were examined and a qualitative assessment of the success was made. This includes not only revegetation within the quarry itself (Visual Berm, Phase I, and other areas), but also the revegetation of roadside disturbances and disturbances in Williams Canyon. Each of these are discussed below in separate sections. Visual Berm: The vegetation on the Visual Berm continues to show strong cover and diversity. Tree and shrub growth is continuing to develop and expand at a rapid rate. Erosional damages in recent years have been essentially none and repairs of previous damages have held very well. Phase I Revegetation: Growths on this area which span about three years of revegetation work continue strong and vigorous. Diversity, however, is low due to the high density of the highly competitive grasses. There has been a slight decline in density and cover of these species and this has provided additional opportunity for native invasion of fortis and shrubs. However, these invasion rates remain very low. Erosion of these areas is very low to non-existent. On small bench collapse is evident, but the effect is judged as minor, even though expansion of the collapse into the next bench up the slope has occurred. It appears the collapse will eventually self repair and no additional work will be necessary. Roadside Disturbances -Crass Cover: Grass cover on all the roadside disturbances is excellent. Cover was estimated at 60% to 100%. Growth is vigorous and erosion is essentially absent on all areas, except number 2 where it is slight due to the very steep slope.
