ALBERT FRET AND SONS, INC. Frei Pit #3 • (Aka Bromley Pit) Permit # M-1979.165 RECLAMATION PLAN -TECHNICAL REVISION Unless specifically discussed below the methods described and approved in the original application, the reclamation plan will remain unchanged. In the 1979 Reclamation Plan a definite end use plan was not well defined. The following text corrects that problem for the final Reclamation at this mine. It is consistent to what was speculated on in 1979 when the fill and final uses were discussed but not firmed up. This revised plan is consistent with the Adams County Planned Unit Development (PUD) permit approved in 2005. Albert Frei and Sons, Inc., will reclaim the site as a combina- tion industrial/commercial site that will allow for having an asphalt batch plant and concrete batch plant on it when reclamation is complete. Accessory uses for each plant includes but are not limited to, truck parking, raw material storage, equipment parking and storage. In addition, the concrete batch plant has a casting area for making minor structural barriers. The site will also include a concrete and asphalt recycling facility where the raw material will come from material generated by on site plants and from clean recy- clable material hauled into the property. We have broken the mine into two areas using the railroad as the dividing line, the eastern parcel where most of the industrial activities will take place and the western parcel that will be used for equipment and truck parking. This Reclamation Plan confirms what was discussed in 1979 and calls for backfilling the mined area so no ground water is exposed and then adding additional fill to level the site so it matches surrounding property elevations. On the eastern parcel, this will create a level area at the approximate elevation of Colorado Blvd. on the east and the railroad on the west. For the western parcel it will be level with the railroad and blend with the inert material landfill adjoining the property to the south. The material to be used is Inert Fill as defined in Rule 1.1(20) and no compaction percentages are proposed. This is due to the nature o£ the material and the difficulty to test for compaction when large pieces of concrete and asphalt are in the filled area. The method of placement also assures adequate compaction for the intended end use of commer- cial/industrial uses. The level parking area (tan color) covers 818 of the permit area on this site. To reclaim this area Albert Frei and Sons, Inc., will grade and shape the level portions of the filled area and where appropriate it will be graveled. In the batch plant areas some paving will be done around the plants to reduce mud. Slopes from the top of the fill to the original ground surface will be 2:1 or less as shown on the map. The level area around the bottom of the fill and the slopes along the railroad ROW and the outer limits of the western parcel will be resoiled and seeded (green areas) using the seedmix listed in Table F. North of the concrete batch plant the slope will be armored with broken concrete to protect the filled area along the spring from erosion. Around the north and east sided of the spring is native vegetation that will remain undisturbed. Along Colorado Blvd the green area was landscaped per Adams Counties PUD approval. It contains a tall wood fence, a stone wall, trees, grass and tree watering system to maintain the plantings. The revised Reclamation Plan Map shows the current and proposed configuration of the site, in that the eastern parcel is completed
