Exhibit D- Mining Plan to the homestead has an active easement for operations which will be used as secondary access for light vehicles and equipment. Immediately south of the residential yard, existing facilities prevent the area from being used other than as a storage or parking area for vehicles, equipment (including heavy equipment), supplies, or other operational support purposes. This location is fully disturbed by prior agricultural and landowner purposes. This may also include the placement or construction of storage structures and materials. The primary access for heavy equipment, service vehicles, haul trucks and related traffic is located along an established access road that traverses the east line of the permit boundary. Both access roads intersect Weld County Road 28 that flanks the northern extent of the permit boundary. A grader and water truck maintain access within the permit area as necessary throughout operations. The aggregate deposit varies in composition, depth and extent. Generally, depths are shallower toward the southeast, trending deeper toward the northwest, and are consistent with the gradient flow of groundwater which appears to be at stasis near elevation 4795 feet. Tract B (East Basin) falls from 15-45± feet and Tract A (West Basin) from 35-60± feet from the surface to the underlying unconsolidated bottom. Unconsolidated suitably derived on-site material may be used for diverse purposes, including commercial products, or the re -grading of the extracted basin. These same materials may also be used to line the completed basins (refer to Exhibit G — Water Resources, Part 6 for details on how completed basins will be lined, if lined). Whether lined or unlined, the basins form the primary end use as developed water resource, and will be utilized accordingly. To facilitate dry extraction of overburden and aggregate, groundwater will be discharged from the areas of active extraction at one or more of the three designated discharge locations identified on Exhibit C-2: Extraction Plan Map. Discharge of waters will be conducted under an approved Colorado Dept. of Health discharge permit, as indicated under Exhibit M — Other Permits. The FEMA designated flood plain was severed in 1911 with the construction of the Union Pacific railroad bed located approximately 1 mile to the west. While found within and along the terminus of the upper terrace of the historic floodplain of St. Vrain Creek, operations will not impact the active FEMA designated floodplain. The general direction of extraction activities over the Tracts is from north to south, as shown on Exhibit C-2 — Extraction Plan Map. No extraction will occur within 125 feet of a residential structure, or ten feet of any other structure, property Varra Companies, Inc.
