EXHIBIT D MINING PLAN AND TIMETABLE LOCATION The property is located in Adams County approximately 2.0 miles northwest of Commerce City, Colorado. The land to the west was part of an old gravel pit operated by Mobile Premix Company in the 1980's which is currently a water storage reservoir for the City of Thornton. This small area has contained the Priola family greenhouses for many years and was the primary residence for the Priola patriarch. It will be a single stage mining operation located on 13.68 ac. ± northwest of Interstate 76 and the west of Dalha St. It is owned by CAP Land Company and leased to Albert Frei and Sons, Inc . Please refer to EXHIBIT B -VICINITY MAP for the property configuration and the relationship to surround- ing geological features. The area to be mined lies in an area surrounded by a water storage reservoir, commercially developed land, agricultural property and an interstate highway. CURRENT CONDITIONS The permit area will cover a 13.68 acre ± parcel with a site elevation of approximately 5090 feet, sea level datum. The northern part of the site is covered by a large greenhouse and office complex while the southern area is mostly used for rural residential and general farm yard uses . The PRE-MINING MAP -EXHIBIT C shows how the area looks at this time. The gravel deposit is an alluvial deposit that averages 15+ feet deep across the property. This deposit will tend to thin as mining progresses from west to east. The numerous buildings and structures located on the site at this time will be demolished and hauled from the site prior to mining commencing. This includes any buried gas, phone and water lines on the site. The operator will contact a buried line location service to check the area for any type of buried utility or gasline that are not owned by the landowners and need to be left when mining is complete. MAPEXHIBITC shows the outline of the mining area, the touch- ing landowners, the 200 foot ownership, current topography, and hydrologic features of the property. The land is presently used for rural residential and agricultural purposes by the landown- ers. Most of the area is highly disturbed where equipment has been stored or used for various agricultural activities. There is little vegetation in and around the buildings on the northern part of the site. The rest of the area has a vegetative cover that would be considered good. Surrounding property uses, 3
