Appendix A Maps Appendix B Introduction The area surrounding this site has provided gravel reserves for the local area for over 30 years. This site will provide the needed reserves for the community. The pit will be mined after the completion of mining at the Chambers Pit located just to the west of the site. 5/26/2005 Page i-1 County Special Use Addendum SP 1.) The following Exhibit is a guide to locating required County Special Use permit information within the CDMG permit application. This Exhibit also includes information not pertinent to the Colorado Division of Minerals and Geology (CDMG) permit application but required by the County Special Use Permit. 2.) Water will be intimately involved with this site, due to mining below the water table. All water issues involved with extraction and processing can be found in Exhibit G of the CDMG Permit Application. Potable water will be brought onsite for workers. Portable Sanitary Facilities will be provided for workers as well. 3.) The site plan/map is included in Exhibit C and Exhibit F of the CDMG Permit Application. Map C-1 represents the pre -mining condition of the site. Map C-2 represents the ultimate mining limits for the site, and Map F represents the site after final reclamation has been completed. Adjacent roadways can be seen on all of the maps. 4.) Map B-1 of the CDMG Permit Application shows the surrounding areas of the proposed areas. 5.) Property boundaries are shown in Map C-1 of the CDMG Application. A list of property owners within 200' of the site is included in Exhibit V. Also a copy of the appropriate County Assessor's map and property deeds have been included at the end of this Addendum 6.) A letter stating right of entry associated with all involved properties are included in Exhibit N. 7.) Greg Lewicki and Associates is acting as an agent for the Landowners for the site. Please see the letters enclosed in this Exhibit. 8.) Please see the following statements which specifically address the appropriate Zoning Regulations. 5.03.07.1(A) 5.03.07.1(B) All water issues are addressed in Exhibit G of the CDMG 112 Permit Amendment Application. As strictly dictated by the CDMG, the mine site may not cause impact outside the permit boundary. The impact of vapor and dust will be mitigated by keeping haul roads and active portions of the pit watered down. Emissions, such as vapor, dust, smoke, and noise, from mobile equipment and processing plants is strictly governed by various Federal, State, and County agencies. All equipment and facilities will be maintained in compliance with these agencies. 5/26/2005 Page SP -1 5.03.07.1(C) 5.03.07.1(D) 5.03.07.1(E) 5.03.07.1(F) 5.03.07.2(A) 5.03.07.2(B) 5.03.08.1 5.03.08.2 5.03.08.3 No blasting will occur on the site, therefore no large vibrations, such that could be sensed offsite, will be generated. Specifics of the Mining Plan can be found in Exhibit D of the CDMG Application, respectively. Greg Lewicki and Associates and United Companies have worked with CDOW in order to minimize the impact of the site. Also the site should be viewed as a temporary impact with the final land use being a high quality, diverse wetland, lake, and riparian wildlife habitat. Soil, Vegetation, and Wildlife information can be found in Exhibits H, I, J, and K of the CDMG Application. As seen in Map Exhibits C-1, C-2, and F, the site only accesses state controlled roads. The primary access for truck traffic on the site will be the existing access to Highway 6 located at the Chambers Pit to the west. The rail crossing and highway access will be connected to the proposed site by an road installed across Richard Casey's property. A letter from Richard Casey is included in the Right of Entry Exhibit. Again, the CDMG requires engineer certified proof that the mining operation will not cause impact outside the permit boundary. As required by the CDMG, the site must be reclaimed to high standards. The site's Reclamation Plan can be seen in Exhibit E of the CDMG Application. Also the Mine Plan included in Exhibit D of the CMDG Application addresses impact mitigation for the operating life of the mine Reclamation/Rehabilitation of the site will be conducted as per the Reclamation Plan included as Exhibit E of the CDMG Application. The CDMG requires that the operator of a mine site post a bond for the reclamation of a site. A CDMG Environmental Protection Specialist calculates the bond based on the complete reclamation cost of the worst-case scenario of the site. An initial estimate of the reclamation tasks and costs is required in the CDMG Application. This information can be found in Exhibit L of the CDMG Application. Emissions, such as vapor, dust, smoke, and noise, from mobile equipment and processing plants is strictly governed by various Federal, and State agencies. Also the mine is surrounded by gravel mining operations to the west and south. The site's remaining border is Highway 6 and 24 with light industrial directly across the highway from the site, and fields to the east. Therefore, the impact to more sensitive areas will be limited. No blasting will occur on the site, therefore no large vibrations, such that could be sensed offsite, will be generated. Emissions, such as vapor, dust, smoke, and noise, from mobile equipment and processing plants is strictly governed by various Federal and State agencies. All equipment and facilities will be maintained in compliance with these 5/26/2005 Page SP -2 5.03.08.4 5.03.08.5 agencies. Except for the initial mining of Phase 1, all portable processing plants will be located in the pit bottom in order to minimize impact to the surrounding areas. Storage areas for the site such as equipment parking and fuel storage will be maintained in compliance with all appropriate agencies. The Mine Plan included as Exhibit D of the CDMG Application contains descriptions of equipment, facilities, and tanks expected to be located at this site. 5.03.08.5(A) All flammable and hazardous materials will be stored in accordance with appropriate codes. 5.03.08.5(B) The visual impacts of the site will be mitigated by locating most of the facilities in the bottom of the pits. Unfortunately the elevation of Highway 6 and 24 and I-70 which are the locations of primary visible impacts, are greater than the property. Berms, fences, and landscaping would have little affect on the visual impact to I-70. However, mature vegetation not located in a mining area, as shown in Map C-2, will be left. Not only does this protect some of the valuable riparian areas, it will provide some visual buffer to the site. 5.03.08.5(C) The site will be allowed to import materials for fill, however the CDMG requires that the fill be inert in nature. Also if acid causing minerals are found on the site they will be left undisturbed and covered with an appropriate amount of fill. 5.03.08.5(D) The storage of heavy equipment will primarily take place in the pit area of the original Chambers Pit located to the west of this permit. For storage in the proposed pit the following applies: 1. The overall permit area far exceeds the lot minimum of 5 acres. 2. The site lies more than a quarter mile from the nearest residence other than the properties included in the permit area. 3. Screening is provided by the parking area being in a portion of the pit bottom. 4. No impacts from maintenance are expected to leave the site. This is due to the large distance to the permit boundary. Please see Maps C-1 and C-2 of the CDMG Application. 5. All loading and unloading of vehicles will take place onsite. 5.03.08.5(E) This operation is associated with natural resources and therefore is not exempt from this regulation. 5.03.08.6 Water information can be found in Exhibit G of the CDMG Application. All storm and process water discharge will be in compliance with NPDES permit. A list of all permits required for the site can be seen in Exhibit M of the CDMG Application. 5/26/2005 Page SP -3 City of Rifle Watershed Permit WP The proposed Glen's Pit lies within the Jurisdiction of the City of Rifle Watershed District. Under Section 10.05.080 (Activity in Progress) of the Rifle Municipal Code (RMC), a Watershed Permit must be filed. Issues relevant to the City of Rifle Watershed Permit will be addressed in this Addendum to the Colorado Division of Minerals and Geology (CDMG) 112 Permit Application. As with the Garfield County Special Use Permit Application, items required by the Watershed Permit, which can be found in the CDMG Application, will be referenced to the appropriate Exhibit within the CDMG Application. Information not covered in the CDMG Application, but required for the Watershed Permit will be addressed directly within this Addendum. Under Section 10.05.050 (Permit and Hearing Procedure) of the RMC, the following items are required. A.1 A complete application form can be found at the end of this Addendum. A.2 The Application Bundle including the CDMG Permit Application, County Special Use Addendum addressing the Special Use Permit, and Watershed Permit Addendum addressing the City of Rifle Watershed Permit will serve as the full and complete description for the proposed activity. A.3 Three copies of the Application Bundle will be submitted. The items required by Section 10.05.050(A)(1)(a-j) are referenced or included below. Additional copies will be provided upon request. A.3a The vicinity map of the site can be found in Exhibit B of the CDMG Application. Both the property description for the site and the proposed CDMG Permit boundary can be seen on Map C-1 of the CDMG Application. A.3b Boundary lines of the property and CDMG Permit Boundary can be seen on Map C-1 of the CDMG Permit Application. A.3c As required by the CDMG, structures with two hundred (200) feet of the proposed activity must be shown. These structures can be seen on Map Exhibits C-1, C-2, and F. The structures and the owners are also listed in Exhibit S of the CDMG Application. A.3d 2 -foot (2') contour information is avaliable for the site. Current conditions can be seen on Map Exhibit C-1. A.3e Accurate 2 -foot (2') contour intervals are shown for final mining conditions as well as final reclamation conditions. Cross-sections of the pre -mining, mining, 5/26/2005 Page WP -1 A.3f A.3g and reclamation surfaces are included as Map C-3. Water control structures associated with the proposed activities can be seen on the appropriate plan view maps. The water control structures and locations will differ throughout the pre -mining, mining and final reclamation of the site. A description of water handling can be found in Exhibit G of the CDMG Permit Application. Importation of materials is planned to occur on this site. The materials will be inert in nature and consist primarily of recycled concrete and asphalt. The materials will be either reprocessed into sellable product or used as backfill material for reclamation of the site. The site will continue to allow importation of materials. A.3h Vegetation of the site is discussed in Exhibit J of the CDMG Permit Application. A.3i Exhibit B of the CDMG application includes a portion of a USGS quad of the vicinity. A.3j The 100 -year flood plain can be seen on all plan view maps included in the CDMG Permit Application. A.4 We feel that while the activities proposed in this plan will not measureably increase the risk to the City's Waterworks or Water Supply. However because we cannot state that the activities pose "no" risk, this project would likely fall under a minor impact permit. The following portion of this addendum addresses the spefic concerns involving the Waterworks and Water Supply. A.5a A study and report was prepared for the city by Schmuesser Gordon Meyer, Inc during the permitting of the Mamm Creek Gravel Pit currently operated by Lafarge. This study, titled "Floodplain Study and Report of the Colorado River from Rifle to Mamm Creek," was produced on February 20, 2001, and submitted during the permitting of the pit in 2001. A.5b Reclamation plans for the site can be found in Exhibit E of the CDMG application. Revegetation and seeding plans can be found in Exhibit E of the CDMG Application. A.5c Information taken from the NCRS soil survey can be seen in Exhibit I of the CDMG Permit Application. A.5d A geologic description of the site can be found in Exhibit D of the CDMG Permit Application. A.5e The complete mining plan can be found in Exhibit D of the CDMG Permit Application. The complete reclamation plan can be found in Exhibit E of the CDMG Permit Application. 5/26/2005 Page WP -2 A.5f Water information for the site can be found in Exhibit G of the CDMG Permit Application. Watershed Permit Specific Information As stated in Section 10.05.010 (Intent of City Watershed District) of the RMC, "...The District and these regulations are created only for the purpose of protecting the City's waterworks and water supply, and not for the purpose of regulating land use activities, which activities shall continue to be regulated by Garfield County, the federal government, and any other authority with jurisdiction over land use activities within the District..." The jurisdiction of the City Watershed District spans only permitting of activities based on the risk of injury to the City's Waterworks and Pollution of the City's Water Supply. Therefore, we will directly address these two issues in this section of the Watershed Permit Addendum. Possible Risks to the City's Waterworks The City of Rifle's water intake structure lies approximately one mile from the nearest edge of the pit excavation. The only foreseeable damage to the structure would be natural migration of the river channel. Throughout the life of a river, the primary channel will migrate. While the meandering of a river's alignment is a natural process, the alignment can be influenced by man- made interaction. The mining and reclamation plans for Glen's Pit have been designed to minimize the risk of influencing the deviation of the river. All excavations occur outside the 100 -year floodplain removing the concern of pit capture during high water events. A culvert will also be installed outside the 100 -year floodplain to allow floodwaters which exceed the 100 -year floodplain to slowly interact with the reclaimed lake rather than overtopping the bank. The threat of lateral channel migration capturing the pit is very minimal. The excavation limits are at least 100 feet from the nearest minor channel and more than 500 feet from the main channel of the river. To further minimize the risk of channel migration causing pit capture, the operator (during mining) or the landowner (after mining) commits to bank stabilization in the event channel migration significantly reduces the 100 -foot buffer between the excavation and the nearest river channel While a statement of no risk cannot be made for this site, it can easily be seen that the site poses a very limited risk to the City's Waterworks. Therefore, we request that this application be reviewed as a minor impact. Possible Risks of Pollution to the City's Water Supply Due to location, the site will interact with the watershed of the City of Rifle. The site will have a discharge point as seen on the CDMG Permit Application. This discharge point falls under the jurisdiction of the Colorado Department of Health Water Control Division. An application for a Process Water and Stormwater Discharge Permit is being concurrently filed. All water discharged from the site will be regulated under this permit. Site runoff will be controlled. Ditches and berms will be used to direct runoff into the pit where sediment will be allowed to 5/26/2005 Page WP -3 settle out prior to the water being discharged. The site lies outside the 100 -year floodplain and is not at risk for floodwater interaction with disturbed areas. Mobile equipment and facilities will be located and used on this site. Equipment fuel tanks as well as tanks associated with the fixed and portable plants will be on-site. An SPCC Plan is being prepared for the site. As dictated by numerous regulatory agencies, all tanks will have secondary containment. This containment will either be integral containment, such as double walled tanks, or tanks will be housed in lined containment areas. While a statement of no risk cannot be made for this site, it can easily be seen that the site poses a very limited risk to the City's Waterworks. Therefore, we request that this application be reviewed as a minor impact. 5/26/2005 Page WP -4 Legal Description Exhibit A General Location The Glen's Pit is located 1.0 miles east of Rifle in Garfield County, Colorado.

All Maps are included in Appendix B. 5/26/2005 Page C-1 Mining Plan Exhibit D Site Description The site lies on the north bank of the Colorado River east of the town of Rifle. The site is adjacent to operating and previously operated gravel pits. Gravel mining began to the west of the site in the 1960's. Three large operating gravel mines surround the site. The MMM Chambers Pit is located directly to the west of this site. The Chambers operation produced the existing pit lake located on Yvonne Chambers Property. An expansion to the Chambers Pit was recently approved by the DMG and is being reviewed by the County and City of Rifle, which includes areas along the south side of the river. LaFarge's Mamm Creek Pit lies directly to the south of this pit and the Grant Brothers pit lies to the east. The permit area consists of 35.51 acres between the railroad and the river. All of the mined areas lie outside the 100 -year floodplain of the river, and most areas have been used for either irrigated fields or stockyards. Site Geology The site contains Pleistocene age gravels with a bedrock of Wasatch Formation shale and sandstone. The gravel depth is expected to be 15-25 feet. The gravel has very little fines and is very permeable. In the irrigated fields, up to 5 feet of overburden is expected with the overburden sharply rising to 15 feet in the northern stockyards. The topsoil is expected to be 3 inches to over 1 foot in thickness. Average topsoil and overburden depths can be seen in the Mining Area Volumes table. The water table level is expected to be around 5330'-5334' in elevation. Pre -Mining Work Pre -mining activities will consist of sediment pond construction, topsoil and overburden stripping, and isolation berm construction. The berm will be a minimum 3 feet tall with 3H:1V slopes and will be constructed with topsoil of Phase 1. Future mining areas will be prepared in a similar fashion. Construction will begin on the water augmentation pond during the pre -mining phase with a majority of the construction taking place during the initial mining phases. Because the gravity drainage will not be useable until the completion of mining, the augmentation pond will be pumped to meet the augmentation needs. Stormwater and Sediment Control Berms and existing irrigation return ditches will isolate the site from the surrounding area. Therefore, all run-off will drain to the pits or lakes. The pit or lake will contain the 100 -Year 24 -Hour Event. The stormwater volume was determined using the calculations below as described in the "Procedures for Determining Peak Flows in Colorado", which includes and supplements Technical Release No. 55 "Urban Hydrology for Small Watersheds." The following calculations are for Mining Area 1. Similar calculations show that all mining areas 11/7/2005 Page D-1 will have more than the necessary containment. All pits will need to be pumped at this operation. Prior to discharge, sediment will be allowed to settle either in sediment ponds or previously mined pits.

Clay loam, silty clay loam, sandy clay, silty clay, or clay. Infiltration rate 0 to 0.05 inch/hr when wet. The storage volume of the pond is calculated as the extraction area above the water table. The water table lies approximately 6 feet below the surrounding surface. This allows for a more than sufficient storage volume for all mining areas.

All water trapped from the storm event will be allowed to evaporate or seep out of the pond within a 24-hour period. Topsoil and Overburden Stripping Topsoil will be stripped and stockpiled as the isolation berm prior to the commencement of 11/7/2005 Page D-2 mining in a particular mining area. After stripping, the topsoil stockpile will be seeded promptly in order to minimize soil loss for any stockpiles which are in place for more than one year. There will be an abundance of topsoil due to the reduction in surface area caused by the formation of a lake within the permit area. This excess topsoil will be used for extra growth media as well as slope backfill material during reclamation. Overburden will be stripped prior to the commencement of mining in a particular mining area. It should be noted that Phase 1 has no overburden. However, there will be an abundance of overburden in Phases 4 & 5. Overburden will be used as backfill for the lake slopes. Details of topsoil and overburden stripping are shown in the Mine Area table. Mine Plan Prior to mining, the pit will need to be dewatered. This will be accomplished by installing a perimeter dewatering trench. The trenches will lead to a sump as shown in Map C-2. Water will be allowed to pass through a gravel berm prior to entering the sump. This will act to filter out a portion of the sediment. All discharge will pass through a sediment control pond in order to allow sediment to settle. The sediment control pond will be monitored for build up. If a substantial amount of sediment has accumulated, the pond will be cleaned. The sediment cleaned from the pond will be placed as fill in the area currently being mined An existing depression onsite will be used as a settling pond. This depression was created by the landowner many years ago as a stock watering pond. Due to the extremely porous nature of the native gravel, the discharge water is expected to seep into the river rather than discharge. However a rip -rap lined spillway will be installed in the existing pond. As mining progresses through the phases, the pumping arrangement will continually change. The locations of the pumps and ditches are approximate as shown on the mine plan map. It is expected that dewatering of a pit will require approximately 1000 gallons per minute pumping capacity. During initial dewatering, the pumping demand may be up to three times the stable pumping rate or 3000 gallons per minute. Once the pit has been dewatered, mining will begin. Primarily, front-end loaders will be used to mine the raw gravel. The slopes of the pit will be mined to 3H:1 V slopes. While mining in the center of the pits a much steeper highwall will be maintained. This highwall will be laid back as it approaches the mining limits. Some dozer pushing or ripping may also be used. The loader will directly load to a primary crusher or into trucks which will deliver the material to the crusher. The road alignments shown on Map C-2 and F are the approximate final location. Current roads as seen in Map C-1 will be utilized until realignment is necessary. If any "reportable quantity" of hazardous material or waste is released into the environment, the operator will notify staff of the Colorado Division of Minerals and Geology as well as all other appropriate local, state and federal agencies. This is more completely described by an excerpt from the February 8, 2002 DMG memorandum regarding Minerals Program 11/7/2005 Page D-3 Notification of Toxic or Hazardous Materials Spills at Mine Sites." "A reportable spill is a spill of any toxic or hazardous substance (including spills of petroleum products) within the permit area reportable to any Division of the Colorado Department of Public Health and the Environment, the national Response Center, the Colorado Emergency Planning Committee, or the State Oil Inspector. The operator shall notify the Office of a reportable spill within the permit area using the same timeframe required by the permit, license, notice, Act, Rule or Regulation governing the reporting of the spill to the appropriate agency. Notice of a reportable spill shall be Faxed to: Minerals Program Supervisor, Division of Minerals and Geology, FAX (303) 832-8106. The FAX shall include a call-back number of a responsible company official for the DMG staff to use as a contact." No explosives will be used on this site for the purpose of mining or processing. No chemicals will be used in the gravel processing. Production Rates The site's production volumes and rates can be seen below. An annual expected average and maximum rate are shown. The life expectancy of the pit is based on the average rate. Construction Materials Annual Production Use Max Rate(t) Average Rate(t) Reject Rate(%) Raw Material(t) Asphalt 200,000 35,000 10% 38,500 Aggregate 210,000 190,000 0% 190,000 Concrete Aggregate 100,000 75,000 10% 82,500 510,000 300,000 4% 311,000 Schedule of Operations The mine is expected to operate from 5:00 AM to 9:00 PM, six days per week with most sales taking place during daylight hours. Activities outside of daylight hours will primarily be maintenance or plant operations. For instance when the portable crushing plant is on site, it will run about 14 hours per day 6 days per week. Occasionally nighttime and Sunday operations will occur to provide for specific demands such as overnight paving work. This schedule is based on the existing Chambers Pit to the west of this site. Operating hours will be based on product demand and may be less than those shown above. Mine Area Details The expansion's reserves are divided into phases. While one phase is being mined the previous phase will be reclaimed. This separation of phases will limit the overall disturbed area. Areas will be mined in order. Reclamation of the slopes will occur promptly after the gravel is mined allowing the pit to then fill with water. Area details can be seen below. 11/7/2005 Page D-4 Mining Areas Gravel Raw Topsoil Topsoil Overburden Overburden Area (acres) Tons* (t) Thickness (ft) Tonnage* (t) Thickness (ft) Tonnage*(t) Phase 1 4.65 203,808 1.00 8,252 0.00 0 Phase 2 4.67 219,386 1.00 8,288 2.50 20,719 Phase 3 3.96 137,207 1.00 7,028 5.00 35,138 Phase 4 5.93 135,340 1.00 10,524 9.00 94,714 Phase 5 2.64 43,996 1.00 4,685 10.00 46,851 Total** 21.85 739,736 38,776 197,423 * Topsoil and OB tonnage is based on the assumption that 1.0 CYD weighs 1.1 t.

Facilities and Mobile Equipment All facilities for the site will be located in or around the pit Portable crushing, screening, washing, cement, and asphalt plants will be brought onsite. A portable office trailer may be used for the scale house and offices onsite. An alternative office plan may use the existing structures until mining progresses into those areas. It is anticipated that processing facilities will be kept in the pit bottom except during the mining of the initial phase. Processing of the initial phase's gravel will occur on the existing surface of Phase 2. The topsoil will be stripped to provide sufficient space for processing.

All tanks will have secondary containment. Tank details can be seen below. Currently, the planned tank for this site has integral secondary containment in the form of double -walled tanks. If a single walled tank is to be used on the site a bermed containment structure with an approved liner will be constructed. The fuel tank will be kept near the existing structures during initial mining Once mining progresses to the final phase, the tank will be moved to allow mining within that area. On -Site Storage Tanks Secondary Volume Construction Containment Contents Location 5,000 Steel Integral Fuel Fuel Farm Mine Access and Traffic The existing railroad crossing and highway access will be improved for this project. The railroad and CDOT have been contacted about the improvements and access permits are being concurrently prepared and submitted. Prior to use new access permits and crossing permits will be filed and approved with the appropriate agencies. The permits are based on a 400 one-way trip daily maximum. This number far exceeds the expected daily one-way trips based on annual production. The expected value is 140 one-way trips based on the production rate, 15 ton haul trucks, 6 days per week, and 48 working weeks per year. It should also be noted that the local traffic will not see an increase. This is due to the closure of the Chamber's Pit removing the same amount of traffic which is being added by the new pit. 11/7/2005 Page D-6 Mining Life Time Table The expected mine life can be seen below. The life is based on the average production rate. If demand changes, the life expectancy of the pit will change. However, in no case will the production maximum be exceeded unless all permits have been revised to reflect this change.

This permit will supply the existing demand of the Chambers site. The pit is wet, therefore dust will be mitigated. All tanks will have secondary containment under the SPCC Plan and discharges are carefully regulated under the CDPHE discharge permit. The final landscape will consist of lakes, wetlands, dry rangeland areas, and cottonwood riparian areas, which will have an excellent appearance from the I-70 corridor, Highway 6 and 24, and will be an asset for wildlife. 11/7/2005 Page D-7 Reclamation Plan Exhibit E General Plan Prior to mining, the site existed as irrigated fields. Most areas disturbed by mining will be reclaimed as lakes or wetlands. Disturbed ground outside the lake and perimeter wetlands will be reclaimed as dry rangeland. Disturbance around the pits will be caused by the installation of topsoil stockpiles, overburden stockpiles, and water handling structures such as berms, ditches, augmentation pond, and settling ponds. To minimize final reclamation tasks, mining phases will be promptly reclaimed after mining has been completed. Final reclamation tasks for the pit will include: final grading of slopes, topsoiling, and dry rangeland seeding of Phase 6 and wetland seeding of fringe around the lake. A 36" culvert will be installed as shown in Map F. This culvert will allow return irrigation water to flow freely through the pond and discharge into the river. Location Reclamation Areas Type Area (acres) Notes Lake Surface Open Water 17.28 Wetland Fringe (Lake) Wetland 0.48 Wetland Fringe (Pond) Wetland 0.12 Discharge Pond Undisturbed 2.57 Augmentation Pond Open Water 1.38 Shores Dry Rangeland 13.68 Total Permit Area 35.51 Earthwork Plan Mining highwalls will be kept at or near vertical until approaching within 45 feet of the mining limits. The slope will then be laid back to the 3H:1 V slope. The slopes may be backfilled with overburden. Ramps into the pits will be left as shallow 7H:1 V sloped areas. To minimize final reclamation tasks, slopes will be backfilled promptly after mining is complete. Re-Topsoiling Plan Topsoil will be replaced in all disturbed areas to 5 feet below the water table at a minimum depth of 12". It is expected that more than 12" of topsoil will be available due to the lake areas not needing topsoil. If this is the case additional topsoil will be placed in the disturbed areas. Revegetation Plan The site will be revegetated as follows: 11/7/2005 Page E-1 Dry Rangeland Wetland The following seed mix is recommended for the upland dry rangeland areas. After regrading, the reclaimed area should be tilled. The seed mix can then be broadcast and mulch applied over the seeding. The mulch will be crimped in at a rate of 1.5 tons/acre. Only certified weed free mulch will be used. Species Lbs/acre Seed, PLS Palome Indian Ricegrass 6.0 Ephraim Crested Wheatgrass 3.0 Canbar Canby Bluegrass 1.0 Sodar Streambank Wheatgrass 3.0 Canada Wildyre 2.5 Slender Wheatgrass 2.5 Fourwing Saltbush 0.3 Rabbitbrush 0.3 Skunkbush Sumac 0.3 Total 18.9 The following seed mix is for the wetland areas. This seed mix should be hand -raked into the soil and covered with mulch, avoiding the compaction of mechanical equipment. The mulch will be crimped in at a rate of 1.5 tons/acre. Only certified weed free mulch will be used. Tubelings or cuttings will also be planted along all lake edges. Cottonwoods, willow, sumac and buffaloberry will be planted in clumps of 10 to 15 trees with the trees spaced about 8-10 feet apart. The clumps will be about 100 to 200 feet apart. Approximate clumps can be seen in the Reclamation Maps Species Lbs/acre Seed, PLS Nebraska Sedge 1.0 Hardstem Bulrush 4.0 Beaked Sedge 1.0 Alkali Bulrush 2.0 Canada Wildrye 2.5 Slender Wheatgrass 2.5 Total 13.0 11/7/2005 Page E-2 Post -Reclamation Use Most of the future site's use will be recreation and wildlife habitat. The lakes will be used primarily for wildlife habitat with some fishing and boating recreational use. The areas surrounding the lakes will primarily be used as wildlife habitat. Most surrounding riparian areas will be left undisturbed in order to provide quality wildlife habitat. Those riparian areas, which have been disturbed, will be planted as dry rangeland. This will provide forage areas for wildlife. To further offset the loss of trees, cutting and sapling planting is planned for the new wetland areas. The re -seeded areas will also be allowed to be naturally overtaken by the riparian areas. Post -Reclamation Site Drainage All run-off will be captured by the pit lakes. This run-off will evaporate or seep into the porous surrounding gravel within 24 hours. Weed Control This area of the state is known to have some weeds of concern such as the thistle group and knapweed. The operator will take extreme care in preventing weeds from establishing infestations in the permit area by doing the following: 1) Each mid-April, a noxious weed survey will be made of the permit area. 2) If any noxious weed patches or plants have been identified, they will be sprayed by backpack sprayer or 4 -wheeler using chemicals approved for use by the local Weed Management Commission. This will be done within 2 weeks after the inspection when the weeds are most vulnerable. Care will be taken to spot spray where possible to avoid killing desirable broadleaf plants. 3) After reclamation of portions of the site and after final reclamation, weed surveys and spraying will continue until the perennial cover and production of the site have met DMG requirements and bond release has been obtained. The local Weed Management Group will be consulted regarding any weed infestation area and any control measures prior to their initiation. The plan does not contemplate total weed removal on the property, especially the removal of some non -noxious weeds. Past experience shows that some initial weed cover in the first year following retopsoiling is beneficial to the reclamation effort in dry range sites. Weeds tend to provide shade for new grasses, are a means of holding snow on the seedbed longer and protect it from wind and water erosion until the planted species gradually take over the site. Revegetation Success Criteria Wetland Fringes The wetland revegetation will be deemed adequate when the vegetation has been established in 11/7/2005 Page E-3 order to control erosion, noxious weeds are not present in any significant amounts, and a healthy stand of wetland plants exist with reasonable diversity as determined by the CDMG. Dry Rangeland The dry rangeland slope revegetation will be deemed adequate when the vegetation has been established in order to control erosion and noxious weeds are not present in any significant amounts as determined by the CDMG. Monitoring Reclamation Success Monitoring the reclamation on an ongoing basis will help to assure successful reclamation. The operator plans to use the local NRCS office to assist in determining the ability of the reclaimed land to control erosion and any other suggestions which may enhance the reclamation of the site. If minor changes or modifications are needed to the seeding and reclamation plan, revision plans will be submitted to the Division as required. It is hoped that the Division will provide assistance in evaluating the success of the ongoing reclamation process. All areas disturbed and reclaimed and any other important items regarding the reclamation will be submitted in the annual reports to the Division. 11/7/2005 Page E-4 Final Reclamation Timetable The site will be mined and reclaimed in phases in order to minimize the disturbed area. It is expected that at the end of the mine life all areas except for the last mining area will have been reclaimed. All final reclamation tasks for this scenario can be seen below.

The pit will be flooded once mining and reclamation has been completed. Controls for both surface and ground water are included in this plan. Surface water exists in two forms in the permit area during mining; being the Colorado River and the sediment pond. The river runs in a westerly direction south of the permit area. A minimum buffer of 100 feet will be maintained between the river and the pit. This buffer will provide a sufficient safety factor against river capture. The second form of surface water will be storm and process water discharge. Substantial water will be discharged throughout the mine's life. Pumping will occur continuously for the life of the mine. Water will be pumped from dewatering trenches into the pond between the pit and the river. Sediment will be allowed to settle in this pond prior to discharge. A discharge permit has been submitted for this discharge point. Once all mining has been completed all pits will be allowed to fill. A gravel well permit and substitute water supply plan will be filed concurrently with this application to account for the water surface after mining has been completed and all depletions during mining. As part of the substitute water supply plan a lined pond will be built on the upper terrace next to the access road. This pond will be designed to store excess irrigation water during the irrigation season to be used as augmentation water during the off season. Rather than being pumped the bottom of the pond will be slightly above the final elevation of the lake surface. A pipe and valve will be installed to allow draining of the pond without pumping. Please see the augmentation pond details in Map C-4. Evaporative depletions from the water surface of the augmentation pond has been accounted for in the substitute water supply plan as well. Due to the close proximity of the pits to the Colorado River, the ground water table will be very high. The expected water table depth lies from 5-10' below the surface. This height will vary depending on the seasons. Wells servicing the Chambers' buildings lie within 600' of the expansion. These wells may be removed as part of the mining operation. A well release from the wells has been included in the substitute water supply plan submission. The following table shows the estimated amount and uses for water for the operation. Until operations begin and all equipment is in use, actual consumption will not be known. 11/7/2005 Page G-1 Operational Water Use Table Use Rate(g/day) Duration (months) Annual Use(g/yr) Annual Use(acre/ft) Road Dust Control 3,000 8.6 1,238,400 3.80 Asphalt Plant 500 4.2 100,800 0.31 Cement Plant 6,000 4.2 1,209,600 3.71 Gravel Evap. (4% by 6,000 8.6 2,476,800 7.60 weight) 5,025,600 15.42 A substitute water supply plan and a gravel well permit will be obtained prior to mining below the water table. An augmentation plan will also be promptly filed for the water use. No mining will take place below the water table until the substitution plan has been obtained or the site's bond will be increased to cover the backfilling of the pit at the end of mining. Due to the pit being near the City of Rifle water intake, a watershed permit issued by the City of Rifle may be needed. Issues involving this permit will be addressed prior to work beginning in the pit. No wells other than the three Chambers' wells are located in the surrounding vicinity which can be affected by the water drawdown from pumping. 11/7/2005 Page G-2 Wildlife Information Exhibit H The proposed permit expansion area consists of irrigated pasture. The current land use is pasture and wildlife habitat. The irrigated pastures provide very little wildlife habitat, except for deer and elk grazing. Riparian areas along the river will not be disturbed by this operation. 1. Significant Game Resources on the Affected Lands Big game species potentially occurring on this site include mule deer, white-tailed deer, and American elk. Mule deer are the most common big game species found on the site. White- tailed deer and elk occasionally visit the site. Mule deer occur on the site throughout the year, typically concentrating in the lush native vegetation near the river. This area provides important mule deer winter habitat and a good source of food. It should be noted that the areas within 100' of the river will not be disturbed. Upland game birds potentially occurring on the site include ring-necked pheasant, mourning dove, and turkey. These species prefer mountain brush and riparian habitats. Again it should be noted that areas within 100' of the river will be left undisturbed in order to provide a buffer against river capture as well as to maintain high quality riparian habitat. The Colorado River and its floodplain and wetlands provide habitat for breeding and migrant waterfowl. Waterfowl likely to occur on the site includes: Canada geese, common and red breasted mergansers, gadwall, American widgeon, mallard, green -winged teal, blue -winded teal, cinnamon teal, northern shoveler, pintail, redhead, canvasback, lesser scaup, common goldeneye, Barrow's goldeneye, bufflehead, and ruddy ducks. The only small game species occurring on the project site is the Nuttal's cottontail. This species occurs mostly in shrubby vegetation and within the riparian habitat. The cottontail and various rodent and ground squirrel species on the site are prey for raptors and other predator species in the area. Predators and other forbearers likely to occur on site include: American beaver, muskrat, mink, ermine, badger, raccoon, red fox, and coyote. 5/26/2005 Page H-1 2. Significant Non -Game Resources on the Affected Lands The project site provides habitat for a diverse array of breeding and migrant bird species. It also provides habitat for raptors as well. Thirteen species potentially occur in the area based on the CDOW Wildlife Resource Information Service. They include: bald eagle, golden eagle, Swainson's hawk, red-tailed hawk, rough -legged hawk, northern harrier, merlin, American kestrel, Cooper's hawk, sharp skinned hawk, northern goshawk, great -horned owl, and long- eared owl. Many of these species are infrequent spring and fall migrants that occasionally pass through the Colorado River Valley. American Kestrel and Coopers hawk are the most commonly seen on the site. An on-site inspection in the fall of 2003 revealed no potential or active raptor nests. However, dense riparian areas provide good potential nesting sites. It should be noted that the areas within 100' of the river will not be disturbed, therefore keeping much of the high quality riparian area intact. 3. Seasonal Use of Affected Lands The pasture land and riparian areas provide good cover and forage throughout the year. Also through the addition of ponds and wetlands to the area during and after reclamation, the site will serve as superb migratory waterfowl habitat. 4. Presence and Estimated Population of Threatened or Endangered species in the area. No threatened or endangered species are known to exist on the site. The beginning of the reach for threatened and endangers fish lies approximately 2 miles down stream from the site, and continues downstream to Grand Junction. The operation will not affect the River downstream in any way, since all runoff and discharge will be carefully regulated and water loss from evaporation will be offset by reducing consumption by irrigation. 5. Fish Resources Only 14 species of fish are native to the upper Colorado: the Colorado pikeminnow, bonytail, humpback chub, razorback sucker, Colorado River cutthroat trout, Rocky Mountain whitefish, roundtail chub, speckled dace, Kendall Warm Springs dace, flannelmouth sucker, mountain sucker, bluehead sucker, mottled sculpin and the paiute sculpin. However, there are numerous non-native species of fish competing for habitat. Down river is the start of the endangered species habitat for the Colorado pikeminnow, razorback sucker, bonytail and humpback chub. Prior to stocking fish in the reclaimed lakes the landowner will consult the CDOW for guidance. 5/26/2005 Page H-2 6. General Effects of the Operation on the Existing Wildlife of the Area Gravel extraction and crushing activities will no doubt create some disturbance to animals near the site. The change in impact from the operation can basically be described as a lessening of habitat for big game and small mammals due to reduction in riparian and pasture areas and an increase in waterfowl habitat due to the increase in wetlands and water areas. It should also be noted that along the entire stretch of river bordered by the project mining has occurred along both shores. Migrating animals will probably avoid the site, but the proposed pit does not block any known migratory routes, and wildlife should be able to move through the area unimpeded. Due to the possibility for animal/vehicle collisions, hauling activities will probably pose the biggest threat to wildlife. Haul trucks should keep to posted speeds and drivers need to remain aware of the potential for collisions. 5/26/2005 Page H-3 Soils Information Exhibit I Soils at the site appear to be as represented on the current NRCS map. The soil types for the permit are listed below. They are also shown on Map C-1. Soil Identificatio Soil Description 40 Kim Loam This deep well drained, gently sloping soil is on alluvial fans and benches. Elevation ranges from 5,000 to 6,000 feet. This soil formed in alluvium derived from shale an sandstone. The average annual precipitation is about 12 inches, the average annual ait temperature is about 46 degrees F, and the average frost -free period is about 125 days. Typically, the surface layer is yellowish brown or light yellowish brown loam about 17 inches thich. The underlying material is light brownish gray loam to a depth of 60 inches. In places the underlying material is stratified with fine sandy loam. 65 Torrifluvents This broadly defined unit consists of deep, well drained to somewhat poorly drained, nearly level soils on flood plains adjacent to to Colorado and Roarinf Fork Rivers and their major tributaries. Slope is 0 to 6 percent. The soils formed in alluvium. These soils are stratified and vary widely in texture and depth. The surface layer ranges from loamy sand to fine sandy loam to silty loam to clay loam. The underlying layers are generally sandly loam or loam stratified with sand, gravel, and cobbles. In some areas gravl and cobbles are on or near the surface. 5/26/2005 Page I-1 Vegetation Information Exhibit J The entire proposed mining area is stockyards or irrigated alfalfa fields. Riparian areas will be avoided.

Topsoil will have been stripped from Phase 1 and 2, which would require topsoiling of the Phase 2 and areas of Phase 1 down to 5 feet below the water table. The slopes of Phase 1 would require regrading. Phase 2 and parts of Phase 1 would require dry rangeland revegetation and the wetland fringe of the pond would require revegetation. The culvert would also be installed in Phase 1.

This will be acomplished by maintaining proper setbacks and buffers between the river and permit boundary. The slope will be kept mild(3H:1V) near the permit boundary to minimize the risk of slope instability. The 100' buffer between the ponds and the river will minimize the risk of river deviation due to pit capture. The following is an inventory of man-made structures within 200 feet of the permit area. All of these structures are shown on Maps C-1, C-2, F. The landowner boundaries are shown on Map C-1.

A copy of the sign certification notice can be seen on the following page. 5/26/2005 Page T-1 Geotechnical Stability Exhibit Exhibit U There are no buildings or any structures outside the permit area which could be affected by the operation. All reclaimed areas will be restored to relatively flat (<5%) slopes except for the shore, which will be reclaimed to a 3H:1V slope with below water slopes of 3.0H:1.0V. The gravel zone has a good mix of fines and gravel sizes and has been fairly well compacted over time. The natural gravel material has some cohesion. This results in slope stability parameters of cohesion and internal angle of friction of high values. When this is combined with a relatively mild slope of 3H:1 V, it is expected that the safety factor for this short slope will be above 2.0. I, Greg Lewicki, P.E., with over 20 years of experience in mine slope safety analysis in Colorado, state that this is true. 5/26/2005 Page U-1 Nearby Landowners Exhibit V The following Parcel ID and ownership information can be refreneced to Map C-1 by the lot number for each parcel.

United Companies has right of entry to mine in a combined 35.51 acres from 3 different parcels along the Colorado River approximately 1 mile east of Rifle. The owners of the parcels are Yvonne, Flint, and Kenneth Chambers. The property has historically been used as irrigated fields, but of recent has been left fallow. Upon reclamation of Glen's Pit, a 17.52 acre lake will be created. After the industrial water consumption, which mining will create, is completed, the water will be used for a wildlife area and recreation. It is planned that there will be one gravel pit with a total exposed water surface area of 17.52 acres upon completion of the gravel mining operation. Call records on the Colorado River show that out of priority depletions generally occur only during the period from April 16 through October 31, according the May 11, 2005 letter to Brent Kerr from Division of Water Resources regarding the expansion to the Scott Pit, which has been enclosed at the end of this report. Mining Operation Mining will occur adjacent to the Colorado River, but outside of the 100 year floodplain, and will be actively mined for approximately 2.8 years. The Glen's Pit will be approximately 25 feet deep with an exposed water surface area of approximately 17.52 acres at build -out. It is anticipated that of the total 740 thousand tons of gravel mined, 385 thousand tons will be mined below the water table. Appendix A contains maps of the reclaimed lake surface as well as a general location map. The Glen's Pit is located in the SE quarter of the NE quarter of Section 11, T6S, R93W of the 6th P.M. The center of Glen's Pit will be located 480 feet from the east section line and 1950 feet from the south section line in Section 11. The total volume of water stored in the Glen's Pit will be 203 acre-feet or 327,500 cubic yards. Plan for Augmentation The Colorado River is considered over appropriated to the east of Rifle. Since mining will occur year round, a Substitute Water Supply Plan has been developed. Depletions Two scenarios exist for depletions: 1. During Mining During the mining phase, losses will occur in five areas: Annual evaporative depletion from 2.57 acres of exposed water surface in the sediment pond is calculated to be 7.726 acre-feet. Depletions for evaporation from the sediment pond can be seen in Table 3, Sediment Pond Evaporation. Depletions for moisture lost in the mined material has been calculated to be 4% of the material mined below the water surface level. It is estimated that 265,200 tons of material will be mined below the water table per year. Assumptions are that mining will occur year round for a 2.8 year period. It has been calculated that moisture will be lost in the mined material in the amount of 0.65 acre-feet per month with a total of 7.80 acre-feet per year. Depletions for moisture in mined material can be seen in Table 5, Mining Water Balance. Washing operations at the Glen's Pit consume some water. Past experience in the area has shown that washing operations consume approximately 500 gallons per day. Typically washing operations take place 4.2 months of the year between May and September. For May through August, there is an average of 22 working days per month, while in September, there are only 5. Converting to acre-feet, approximately 0.143 acre-feet per year will be allocated to dust control, or 0.034 acre-feet per month for May through August and 0.008 acre-feet for September. Depletions for washing operations can be seen in Table 5, Mining Water Balance. Asphalt Plant operations at the Glen's Pit consume some water. Past experience in the area has shown that washing operations consume approximately 500 gallons per day. Typically washing operations take place 4.2 months of the year between May and September. For May through August, there is an average of 22 working days per month, while in September, there are only 5. Converting to acre-feet, approximately 0.143 acre-feet per year will be allocated to dust control, or 0.034 acre-feet per month for May through August and 0.008 acre-feet for September. Depletions for asphalt plant operations can be seen in Table 5, Mining Water Balance. Concrete operations at the Glen's Pit consume some water. Past experience in the area has shown that washing operations consume approximately 3,000 gallons per day. Typically washing operations take place 4.2 months of the year between May and September. For May through August, there is an average of 22 working days per month, while in September, there are only 5. Converting to acre-feet, approximately 0.856 acre-feet per year will be allocated to dust control, or 0.046 acre-feet per month for May through August and 0.008 acre-feet for September. Depletions for concrete plant operations can be seen in Table 5, Mining Water Balance. Dust will be controlled by water. Past experience in the area has shown that dust control for roads consumes approximately 3,000 gallons per day, for an average of 22 days per month. Converting to acre-feet, approximately 2.431 acre-feet per year will be allocated to dust control, or 0.203 acre-feet per month. Depletions for dust control can be seen in Table 5, Mining Water Balance. Total annual depletions from the gravel mining operations are estimated to be 19.098 acre-feet per year during the mining phase, with 12.977 acre-feet per year being out of priority depletions. Total annual depletions can be seen in Table 5, Mining Water Balance. 2. After Mining Once mining has completed, the only loss will be an evaporative loss from the exposed water surface which the gravel mining operation creates. Annual evaporative depletion at mining completion from 17.52 acres of exposed water surface at the Glen's Pit is calculated to be 52.67 acre-feet, with 42.91 acre-feet being out of priority. Table 4 located in Appendix B shows calculations of evaporative depletions from the reclaimed lake at Glen's Pit. Table 6 shows the Post Reclamation Water Balance. Total out of priority annual depletions from the gravel mining operations are estimated to be 42.91 acre-feet during the post mining phase of the operation. Credits The only credits which will be claimed for the Glen's Pit is for the precipitation in the area. As seen in Table 1, the monthly precipitation has been taken into account versus the monthly evaporation. Operation of Plan for Augmentation The Colorado River is over appropriated during the period of April 16 through October 31. Flint and Kenneth Chambers own a very senior water right in the Grand River Ditch which will be used to replace evaporative and mining depletions for all out of priority depletions. During times of valid downstream calls on the Colorado River, water will be diverted back into the river system to replace out of priority depletions at Glen's Pit. The maximum amount of water which will be diverted will be 42.91 acre-feet annually.

Water Division 5, Water District 14 Deer Mr. Kerr: sill Owren Governor Rid Costes aecull,.t director !iii 0. Simpson, P.E. State Enii,incor Condition 8 has been modified to reflect that the annual total product mined at the Scott Expansion of the Chambers Pit shall riot exceed 300,000 tons per year (60,000 tons per year above the water table and 240,000 tons per year below the water table). The remainder at the approval is also restated below for convenience. This letter is in response to your application of June 15, 2004 requesting a substitute water Supply plan (SWSP) fora sand and gravel pit to be operated by the applicant, United Companies. In accordance with 37-90-137(11) C.R.S. The Applibant shell be responsible for compliance with this plan, but the State Engineer's Office may also pursue the landowner, for eventual compliance. The required fee of 51,343 tor the substitute water supply plan has been paid. The proposed plan anticipates a maximum year net depletion of 57.87 axis -feet for up to 55.52 acres of exposed groundwater surface. Depletions torn the mining cif this proposed operation will accrue to the Colorado River. Call records on the Colorado River show that out - of -priority depletions generally occur only during the period form April 16 through October 31. As a result, the maximum anticipated out -of -priority depletions associated with this operation for the approved period is 12.90 acre-feet. Evers though the operator of this aggregate mining operation anticipates dry mining of the Scott Expansion of the Chambers Pit by dewatering, the proposed plan accounts for evaporative depletions as if the excavation were not dewatered. Bemuse this is a new Yining operation, no groundwater was exposed within the permit boundary prior to January 1, 1981. You have provided a monthly breakdown of the maximum annual depletions totaling 208.29 acre-feet of evaporative lass from a maximum of 55.52 acres of exposed groundwater, 1.86 acre -fejt of water used and consumed for dust control, and 7.11 acre-feet of water lost with the mined product. A phreataphyte Credit of 159.39 acre-feet has been applied to this plan based on the 17.64 acres of high-density growth willows and cottonwood trees and 23,86 acres !Mf ^,H\,; i'C;4PV, Di.

Because the exposed groundwater associated with ties mining operation is to be loomed less than 100 feet from the Colorado River, all depletions to the river system are assumed to be instantaneous. The proposed source of replacement for this pit is the dry -up of 21.0 acres of historically irrigated land under the Last Chance Ditch, which was decreed for 60 cls on May 5, 1888 with an appropriation date of March 23, 1887. A total of 21.0 acres historically irrigated by 42 shares in the Loesch and Crann Ditch Company will be dried up and made available to offset depletions created by this operation. The 42 shares equate to 0245 cis. This amount is more than adequate to offset the out -of -priority depletions to the Colorado River created by the operation during the two years of this mining operation. The monthly depletions and replacement requirements for a phased operation, beginning with Area 1, proceeding to Area 2, then finishing in Area 3, oen be found on the attached table. As required by Section 8 of Senate Bill 89-120, this substitute water supply plan has been provided to an outside consultant for review. The consultant has recommended approval of the plan by way of a draft of this letter. Based upon statutory requirements and the recommendations of the consultant,1 hereby approve the proposed substitute water supply plan in accordance with Section §37-90-137(11), C.RS,, subject to the following condifons; 1. Unless otherwise revoked or modified, this plan shall be valid through May 3, 2007. If this plan will not be made absolute by 2 water court action by the plan's expiration date, a renewal request must be submitted to this office with the statutory fee (currently $217) no later than February 3, 2007. 2. A well permit must be issued for the gravel pit in accordance with Section §37-90- 137(2) and (11), C.R.S prior to the exposure or use of groundwater_ A well permit application was submitted to this office under receipt no. 528122 and this application is pending evaluation, Until a gravel pit well permit is approved. consumptive use and exposure of groundwater on this site LS prohibited. The provisions of §37-90-137(2) C.R.S. prohibits the issuance of a permit for a well to be located within 600 feet of any existing well, unless the Stats Engineer finds that circumstances so warrant after a hearing held in accordance with the procedural rules in 2CCR402-5. This hearing may be waived If you are able to obtain statements from the owners of all wells within 600 few, verifying that they have no objection to your use of the proposed well. Should a new well permit be denied for reasons of 600 foot spacing, or any other legitimate reason, approval of this substitute supply plan will be cancelled. 3. The total surface area of the groundwater exposed at the Scott Expansion of the Chambers Pit must not exceed 55.52 acres during the approval period of this SWSP and the maximum annual evaporative loss shall not ezcaed 208.2 acre-feet. 4. The annual total product mined at the Scott Expansion of the Chambers Pit shall not exceed 300,000 tons per year (60,000 tons per year above the water table and 240,000 tons per year below the water table), resulting in 7.11 acre-feet of water lost with the mined aggregate and an additional 1,86 acre-feet of water lost due m dust suppression, MAY- .DID lel.

December 12, 2005 CDOT Region 3 — Traffic and Safety 222 South 6th Street, Room 100 Grand Junction, Colorado 81501 Attn: Daniel Roussin Re: Glen's Gravel Pit Auxiliary Turn Lane Assessment Access Road along SH -6 between Rifle and Silt, Colorado Dear Mr. Roussin: This letter presents the results of a Level Two Traffic Engineering Evaluation for an auxiliary turn lane assessment for the proposed Glen's Gravel Pit. The project is to be located along the south side of SH -6 east of County Road 210 (CR 210) between Rifle and Silt. SH -6 access to the proposed project is anticipated to be from an existing gravel road. The General Area Map and Figure 1 attached identify the project location. According to the State of Colorado State Highway Access Category Assignment Schedule, SH -6 is a category R -A roadway east of CR 210 to First Street in Silt, Colorado. SH -6 has a posted speed limit of 55 miles per hour through the study intersection. The existing gravel road approach to SH -6 operates with stop control. The existing intersection laneage and control is shown in attached Figure 2. Site -generated traffic estimates are determined through a process known as trip generation. For this study, Kimley-Horn used information provided by the client to determine the number of vehicles anticipated to enter and exit the site during the AM and PM peak hours, as well as the number of vehicles anticipated to access the site per day. The following table identifies the anticipated trip generation for the project. ■ TEL 303 228 2300 FAX 303 446 8678 ■ Suite 1050 950 Seventeenth Street Denver, Colorado 80202 ❑ V Kimley-Horn and Associates, Inc. Mr. Daniel Roussin, December 12, 2005, Page 2 Glen's Gravel Pit Traffic Generation Distribution of site generated traffic on the street system was based on anticipated travel patterns to and from the site provided by the client. The directional distribution of traffic is a means to quantify the percentage of site -generated traffic that approaches the site from a given direction and departs the site in the same direction. Figure 3 illustrates the expected project trip distribution for the site. Traffic assignment was obtained by applying the distributions to the estimated traffic generation of the development. Traffic assignment is shown in Figure 4. According to the State Highway Access Code, a left tum deceleration lane with taper and storage length is required for any access with a projected peak hour left ingress turning volume greater than 10 vph with the taper length included within the required deceleration length. According to the State Highway Access Code, a right turn deceleration lane and taper length is required for any access with a projected peak hour right turning volume greater than 25 vph with the taper length included within the required deceleration length. Based on warrants, right and left turn deceleration lanes are not required at the proposed access road intersection along SH -6. The intersection of SH -6 and the proposed access road location is in close proximity to existing railroad tracks. Based upon information provided by United Companies, we believe that there is sufficient distance (approximately 95 feet) for a single truck to queue between the existing railroad tracks and the eastbound through lane of the highway. Based upon the length of the trucks (approximately 62 feet), it is anticipated that they would not extend into the through travel lane. The Manual on Uniform Traffic Control Devices (MUTCD) recommends that Storage Space Warning Signs be installed since the distance from the edge of the track to the edge of the parallel roadway is less than 100 feet. Due to the highway and railroad tracks being separated by less than 100 feet, the MUTCD states that "Highway -Rail Grade Crossing Advance Warning" (W10-11) signs shall be installed on each approach of the parallel highway to warn road users making a turn that they will encounter a highway -rail grade crossing soon after making a turn. These signs should exist today due to this being the existing condition. It is recommended that these signs be verified for their existence. Otherwise, new "Highway -Rail Grade Crossing Advance Warning" signs should be placed in accordance with the guidelines of Intersection Warning signs in Table 2C-4 of the MUTCD.
