,1. &07g Pit PeR71it Robins Construction, LLLP a) Top soil will be removed to a depth of 6 to 12 inches and placed on the north side of the area to be excavated, in na berm running the length of the pit and approximately 4 feet tall. b) The excavation will not be greater than 3:1 slopes, nor will the berm have greater than 3:1 slopes. c) When the excavation has been completed, top soil will be replaced to a depth of at least 6 inches and revegetated according to NRCS recommendations herewith. i. The site will be seeded immediately after mining has been completed, but in such a way that germinated seed will have time to grow prior to freezing weather. The seed bed will be disced and harrowed to eliminate compacted conditions. ii. The seed mixture will specified by the NRCS and is expected to be readily available in quantity from Arkansas Valley Seed Company as typical reclamation mix for the dry areas of the San Luis Valley. A mixture is enclosed with Exhibit D iii. The seed mixture will be broadcast with a utility vehicle towing a PTO (power take- off) driven broadcaster. iv. The mulch -seed mixture will be crimped into the soil with grousers on the tracks of a small dozer. V. We expect to establish small trees as recommended by the NRCS, probably the type used for windbreaks that will be planted with gel bags during the early spring months or early fall. Since water will be available, a drip irrigation system will be established. Probably not more than 20 trees per acre will be planted on the berm area. if this creates a shortfall of topsoil for reestablishment of soil on the pit slopes, crusher fines will be used to attain depth sufficient for establishment of grasses and forbs. vi. No ponds will be excavated for this operation. Prepared BY: SNnnnif Engil7eef'irlg CO 44 S"71Ul'fftnN&g Job Number: 1707122CE 719-589-6147 Alamosa, CO 196
