6.4.4 Exhibit D -Mining Plan <br />10. Mining in the newly expanded area will be conducted over a five (5) year period. <br />11. The approximate area and location, together with the year of extraction and reclamation are <br />shown on the mining and reclamation maps. <br />12. An alluvial deposit of rock sand and silt deposited by the Conejos River will be mined to a <br />depth of approximately 30 feet maximum. The deposit extends to a depth of at least 40 feet. A <br />thin layer of topsoil (less than 6 inches deep) will be removed and stockpiled as protected by <br />seeding and mulching with lbs pure live seed (NRCS)reclamation mix and straw. <br />13. The primary material to be produced is crushed gravel for road construction, site preparation <br />and aggregate for concrete. The secondary material is crusher rejects which are used for supply <br />to CDOT for sanding Cumbres and La Veta Passes. <br />14. Topsoil may be stockpiled for more than one season and will be seeded and mulched as <br />described in response to item 12 above. <br />Exhibit E- Reclamation Plan <br />15. Reclamation for the remainder of the existing pit will begin this year (2010) and end in <br />2011.Reclamation for the pit addition will begin in 201 land end in 2015. The area in the existing <br />pit which will not be used for stockpiles will be reclaimed by first distributing previously <br />stockpiled topsoil together with crusher fines over the area to a depth of 4 to 6 inches and then <br />seeding and mulching according to the NRCS recommendations provided herein. Finally the area <br />will be irrigated as necessary with water from well that has an augmentation certificate from the <br />Conejos Conservancy District allowing said use. Each area in the pit addition will be reclaimed <br />in a similar fashion over a five year period from 2011 to 2015. All reclamation operations will be <br />accomplished with machinery and automatic irrigation equipment. No hand labor is anticipated <br />in any phase of reclamation. <br />16. Areas and of the original pit have been graded to their final configuration. <br />17. The post mining use of this property is intended to be a residential subdivision of <br />approximately 20 single family dwelling lots. The area to the east, west, and north is currently <br />populated with typical vacation ( and some permanent ) residences.
