Vernon, M /J . 7 .76-a 7 - /!'Li Executive Director Weld County Board of GREL- ' County Commissioners Certified Mail No. P12201549 Box 758 Return Receipt Requested Greeley, Colorado 80632 Gentlemen: The Hazardous Materials and Waste Management Division of the Colorado Department of Health (the Department) has completed its review of the operational plan and engineering report submitted November 13, 1986, by Coors Energy Company. The proposed site is located approximately 8 miles north of Keenesburg at the Coors Keenesburg Mine. The application was reviewed to determine if the proposed facility could comply with the minimum standards of the Solid Wastes Disposal Sites and Facilities Act, Article 30, Title 20, Part 1, C.R.S. 1985, as amended, and with the regulations promulgated thereunder, 6 CCR 1007-2. Contained within the application are the following major commitments agreed to by the applicant: 1. The site will dispose of fly ash and bottom ash from the Coors Golden power plant along with small amounts of wood, paper, and scrap from site mining activities. The ash will consist of approximately 50% fly ash, 50% bottom ash and contain 30% moisture by weight. Approximately 100 cubic yards will be disposed of per day. 2. Ash disposal will occur seven days a week, from 3:00 a.m. to 11:00 p.m. 3. The dragline operator and dragline oiler along with the dozer operator will construct the disposal areas and truck drivers will unload the ash. 4. Records will be maintained at the site on incoming wastes, water quality monitoring, and variations from approved operation procedures. 870280 Weld County Board County Commissione , March 9, 1987 Page two 5. The ash disposal areas will be located in the area designated as B-pit and will be approximately 25 feet deep, 120 feet wide, and 162 feet long. Disposal of ash will take place at approximately 40 feet above the "spoils" water table. The mining plan requires that the dragline prepare a bench to work on at 4775 feet elevation. This requires that a working area be left at the end of the pit to allow room for the dragline to move over to the next pit. The holes left at an elevation of 4775 feet from the dragline will be utilized for the ash disposal areas. Ash will be dumped into the holes from the edge and will progress northward. Intermittently, clay will be placed over the ash to inhibit fugitive dust and leaching due to precipitation. Full ash areas will be dozed down and covered with clay. 6. Cover will be applied for fugitive dust control as needed. 7. Final cover will consist of a minimum of 2 feet of cover and 1 foot of topsoil. 8. If any unforseen impact to the environment occurs due to the site, Coors Energy will immediately begin remediation and notify the Colorado Department of Health and the Mined Land Reclamation Division and immediately begin remediation. 9. Closure of the disposal areas will include returning the site to its approximate orginal contour and revegetating the area. 10. The existing groundwater monitoring program will continue after closure until the Mined Land Reclamation Division determines it is no longer needed. Based upon review of the application, this Division has made the following findings: 1. Fly ash and bottom ash constituents are liable to change as coal sources and boilers change at the Golden plant. 2. The facility sumps and sedimentation ponds appear to have the potential of impacting groundwater and/or ash disposal areas. 3. A waiver from section 4.6.1 which requires daily cover was implied. 4. The working face of the ash disposal areas will be very extensive at approximately 120 feet across. 870280 March 9, 1987 page three 5. Ash wastes will possibly be exposed for extensive periods of time prior to covering and will be subject to precipitation and wind impacts. 6. Intense surface water run-off events could potentially wash exposed ash out of the disposal areas into the bottom of B pit. 7. The present groundwater monitoring program does not provide adequate representation of groundwater that will be directly downgradient of the ash disposal areas. It is this Department's assessment that if the proposed facility is constructed and operated as designed to include this Division's recommendations, the facility can comply with the minimum standards of the Solid Wastes Disposal Sites and Facilities Act, Title 30, Article 20, Part 1, C.R.S. 1985, as amended, and with the Department regulations adopted pursuant thereto. The Department's approval is contingent upon the inclusion of the following recommendations as part of the Certificate of Designation, if issued. 1. Annual fly ash and bottom ash analysis which must include but not be limited to E.P. toxicity, must be submitted to the Department. In addition if at any time a boiler, or source of coal is changed at the Golden plant, E.P. toxicity analysis of fly ash and bottom ash must be submitted to the Department immediately. 2. Due to the potential impact of the site sumps and sediment ponds on the ash disposal areas and vice versa, the sump and sediment ponds must be maintained at a distance of 500 feet from the boundaries of the ash disposal areas. 3. Covering of the ash wastes must occur on a regular and frequent basis. Covering of ash wastes with a minimum of six inches of cover material must occur every 48 hour period. 4. The working face or exposed area of ash at any one time cannot exceed 60 feet across. 5. A minimum of two additional groundwater monitoring wells must be constructed and emplaced downgradient (northeast) of the main ash disposal area of B-pit, which will monitor the overburden groundwater. The wells must be constructed in accordance with the Water Well and Pump Installation Contractors Act and the location of the wells must be proposed to the Department and approved. Sampling of the wells must occur on a quarterly basis for the same parameters as required by the Mined Land Reclamation Division for the 1986 monitoring program. Additionally, all quarterly groundwater monitoring data must be submitted to the Department. 870280 March 9, 1987 page four 6. Annual records must be submitted to the Department which depict the current status of all ash disposal areas as locations advance. 7. Reclamation (grading, final cover, revegetation) of ash disposal areas must commence immediately upon final filling of an area. 8. All requirements of the Mined Land Reclamation Division must also be met in addition to this Department's recommendations All applicable permits of the Air Pollution Control Division must be obtained prior to the construction and/or operation of any activities for which they are required.

The coal mined (1000 Tons/Day) at this location is trucked to the parent company power plant in Golden, CO. The ash waste (fly ash and bottom ash) generated by this operation is presently slurried from the holding bin on a daily basis, reduced by centrifuging in moisture content to 30% by weight and trucked to the Parfet clay pit in Golden. The quantities are 50 c.y. daily of flyash and 50 c.y. daily mixed bottom ash. The material has a texture resembling sandy clay that is dry enough to be handled by ordinary dump trucks and wet enough to not cause any fugitive dust problems in the municipality. Coors proposes to change the waste disposal site from the present location or to concurrently use the Keenesburg Mine. The mine disposal sites would be located at the ends of .the mine-:strips as shown on the attached area map and would be changed every sixmonths or so, as required reclamation follows the mining operation. 10 other words, each small disposal site would be used tp collect approximately 18,000 cubic yards of this wet flyash/bottom ash mixture after which time the site would be returned to original contour, topsoiled and seeded. The sites would all be above the spoil ground-water table as presently monitored in the reclamation areas and at least four feet below final reclamation elevation. The sites would be in Laramie clays which in their natural state are quite impervious and in most cases would also be covered with clay S70280 before the final topsoil is replaced. Leachate tests show that the ash is as good or better than the enclosing clays from a ground-water standpoint, although only downward percolating rainfall is expected to come in contact with the buried ash and that only during the spring runoff or the occasional 1" - 2" storms received in May and June.

The land is gently rolling with maximum slopes of 10% and general slopes of 1% or less. The land is sand sage prairie habitat with many blowouts. The larger blow outs have the steeper slopes generally on the southeast sides where the prevailing winds have scooped them out. There are no drainages and no erosional features as the deep surface sands readily absorb all of the possible runoff. Although there are many hollows due to the blowouts, water never accumulates in these hollows. 4.1.2 Flood Plains Refer to Sec. 4.5.5, Ash Disposal on or adjacent to Alluvial Valley Floors and Flood Plains. 4.1.3 Through 4. 1 .6 Please refer to Sec. 4.5. 1, Description of Hydrology. Also, refer to Appendix A, Water Resources and Impact Evaluation Report. 4.2. ENGINEERING DESIGN STANDARDS 4.2.1 From test results completed by Hazen Research, Inc. , it was determined that the ash material is not a pollution hazard to the ground-water or surface water system at the disposal facility. Analyses reports and additional comments are presented in Appendix 8, Ash Test Results. 4.2.2 No surface water stream, pond or lake exists within a limit radius of the proposed disposal site. In addition, there are no surface water diversions, structures, berms, channels, canals, or ditches used for the watering of livestock or irrigation needs. 4.2.3 Refer to Section 4.4.4, geologic hazards. 4.2.4 Refer to Appendix A, McWhorter Report, for monitoring well construction diagrams. _�_ 870280 4.2.5 Adequate Cover It is not anticipated that fugitive dust will be a problem with this moist material. However, if it does appear to be a problem, a daily application of at least 6" of sandy clays will be bladed over the exposed ash. There is an unlimited amount of this material in the immediate vicinity. Assuming a delivery of 100 cubic yards/day of ash placed in a five foot deep layer, 10 feet wide and 54 feet long, a 6" cover will require 10X54X.5 = 10 yards of covering material. 27 Intermediate cover is not considered necessary. 4.2.6 Final Cover At a minimum Coors is required to replace 3 feet of topsoil in all areas including the ash pits. This topsoil consists of eolian sands with silt and organic material. There will be no erosion because these pits will be reclaimed to less than a 5x grade. The cover material will come from other parts of the mine or from stockpiles. There is twice as much topsoil presently being saved as is required for 3 feet of cover. Assuming each pit will be used for six months or 18,000 cubic yards 25' deep and 120' wide, the length of these pits will be 25X120XL . 18,000 c.y. L = 162' . Therefore topsoil 27 requirement will be 3X120X162 = 2,160 cu. yds. , a minor part 27 (2%) of the total topsoil required to reclaim approximately 20 acres every six months. Disposal sites will be no more than 1/2 acre in area. 4.2.7 Water Coors does not anticipate that any water will be used for construction purposes. Fugitive dust, if any, will be controlled by covering the ash with overburden as described in 4.2.5 and 4.2.6. Coors does have two water wells and pit water sumps which could be used if necessary. Water use at the Keenesburg Mine has been limited to the following activities: - Reclamation Revegetation - Dust suppression, ash disposal operations. - Office, Shop, Drilling, and other needs - Evaporation A) Reclamation Revegetation - Irrigation Irrigation water for reclamation revegetation will be obtained from non-tributary and tributary sources. A Bauer Rainstar single nozzle head sprinkler system has been used to irrigate approximately 40 acres of land annually. For an average precipitation year, approximately 16.70 ac-ft of water is used to irrigate newly seeded areas on reclamation. Precipitation during the irrigation season averages 3.93 inches. -2- 870280 B) Dust Suppression - Ash Disposal Operations. There would be no additional water requirements for the disposal of ash. Dust suppression needs at the mine for mining purposes is approximately 1 .86 ac-ft/year. C) Office, shop, drilling and other needs Potable water and other needs were supplied from deep well No. 24650-F. Approximately 1 .49 ac-ft of water was used to supply shower and sanitary facilities. From meter readings, the total amount of well water used in 1985 is 5.25 ac-ft. Therefore, 3.76 ac-ft of water was used for other purposes such as equipment washdown, drilling water and other shop/mine related uses. D) Evaporation In 1985, the consumptive use of surface runoff, subsurface water seeps and trapped pit water through evaporation primarily involved open sumps, sediment pond No. 2. , the dugout area, and A/B Pit. Free water surface area, the time duration that the structure existed, and the net evaporation for each structure is summarized in the table presented below.

From the calculations above, a maximum of 10.09 acre-ft of water from non-tributary or other water rights would be required if called. Coors Energy Company has an annual appropriation of 167 acre-ft between the two Laramie-Fox Hills aquifer wells. Even though one of these wells is unsuitable for most needs (except dust suppression) 167 acre-ft of water is still available to augment. However, the maximum production potential for the Laramie-Fox Hills well #1 is 8.62 ac-ft per month or 103 acre-ft/year. To date, water has not been called and thus Coors Energy Company has not had to release water to cover consumptive use of tributary water due to mine operations. The average consumptive use of tributary water at the Keenesburg Mine is approximately 1.65 acre-ft per month, with a maximum net use of 2. 18 acre-ft during the month of June. The minimum consumptive use periods are during the winter months, and amounts to approximately .17 acre-ft per month. Coors Energy Company has the ability to produce enough water from the Laramie-Fox Hills well #1 to meet the needs of the mine while an augmentation plan is in effect. To date, there have been no measured detrimental effects to the Ennis Draw sub-surface water system either in quantity and quality. The net amount of water used from Ennis Draw is approximately 2.56 ac-ft of water per year, (see table above) . There are no wells in Ennis Draw that have been or are anticipated to be impacted by mining activities. 4.3 GENERAL DATA 4.3.1 Site Description Keenesburg Mine Box 359 Keenesburg, Colorado 80643 Weld County Sections 25,26 & 36 T 3 N, R 64 W. Half acre sites will vary according to where mining is taking place. 4.3.2 Area Each site will be no more than 1/2 acre. Coors estimates 2 sites per year required and a mine life of 7 to 17 years for a total site acreage of 7 to 17 acres. -6- 870280 4.3.3 Waste Stream The only waste that will be accepted other than the present wood, paper and scrap from the mine is a 50-50 mixture of flyash and bottom ash from the Coor's Brewery Power plant. (See chemical analysis and leachate tests in appendix) . Quantities will not excedd 100 cubic yards per day. No ash or other waste from any other source will be accepted. The mine operates 24 hours per day, seven days a week so that no one can enter the property without being monitored. Security guards are employed during any special times, such as, holidays and group vacation periods. There are no stream laid deposits holding a stream within 2 miles of the ash disposal, life-of-mine boundary, See Appendix D-1 . Ennis Draw which lies immediately on the east of the boundary does not hold a stream. Ennis Draw is a relatively broad, flat, topographic low in which no stream channel is defined. No evidence of a presently existing perennial, ephemeral, or intermittent stream in Ennis Draw has been observed. There is subsurface evidence that a stream once existed in the draw, but these deposits have been covered over by the existing wind blown deposits. As shown in Map 4.6.3 (e) , the subsurface water system of Ennis Draw has been conducted adjacent to the draw. There has been none, nor is there anticipated to be, a significant impact to the ground-water levels in this area. Box Elder Creek is located about 3 miles west of the proposed ash disposal site. At this time, however, it is not anticipated that ash disposal will progress far enough west to effect ground-water flow to box Elder Creek. As explained in the report of hydrologic investigations, the quality of post ash disposal activities on the ground-water is not expected to differ substantially from that which now exists. (See Water Quality Data, Section 4.5.7, Water Quality and Appendix B, Ash test results) . Therefore, neither the quantity nor quality of waters associated with Box Elder Creek or Ennis Draw are expected to be affected. In any case, the discharge through the life-of-mine area is very small . The ground-water discharge through the area was previously estimated to 5.4 ac-£t/yr or only 3 gpm, however, based on observations of the active pit area, this discharge rate through the area may be high. -7- 870280 4.3.4 Service Area The site will only serve the Keenesburg Mine and the ash from Coor's power plant. There is a hard surface road from Keenesburg to the mine site. From the mine gate to the site there will be a maintained dirt road. Drivers bringing in ash will be directed to the site and monitored by the shift foreman as to proper dumping procedures. 4.4 GEOLOGIC DATA The area of ash disposal activity is located in the northeast portion of the Denver Basin. Consolidated and unconsolidated sediments up to 14,000 feet are found in the deepest portions of Denver Basin. These deposits range in age from Cambrian to Holocene and are underlain by Precambrian igneous and metamorphic rocks. With relation to the mining area considered for ash disposal, only the Cretaceous Laramie Formation and adjoining formations are described in more detail below. 4.4. 1 Unconsolidated Data and 4.4.2 Consolidated Data The geologic formations of major interest that will be affected during mining and ash disposal activities are the unconsolidated eolian sands and the underlying Laramie Formation clays, clay-shales, claystones, sands and the uppermost coal seam. The unconsolidated sands that overlie the Laramie formation (bedrock) consists of fine to median grained, subrounded-rounded eolian sand. These buff to tan colored sands are poorly cemented and very permeable. Thickness of this wind blown sand deposit ranges from 5' to 40' and is randomly distributed through the immediate region. The Laramie Formation typically consists of interbedded brackish water and fluvial beds of shale, clays, clay-shales, claystone, lignite and sandstone. In the Denver Basin, the Laramie is often divided into two members. The lower part consists of shale, claystone, lignite and lenticular channel sandstones, approximately 280 feet thick. The top of the lower member is defined as the top of the upper most lignite bed. The upper member of the Laramie Formation is 60 - 180 feet thick in the mine area and consists primarily of shale, clay-shales, claystone, mudstone concretions and siltstone with minor amounts of sandstone. Portions of this upper member are characteristically weathered and overlain by 5-60 feet of unconsolidated eolian sand. 870280 -8- The clays and clay-shales found in the Laramie Formation can be defined as uncemented or weakly cemented, overconsolidated clays generally exhibiting the following properties: 1 . low strength. 2. has swelling and shrinking potential with increases and decreases in moisture content. 3. has a tendency to "slake" (decompose) when exposed to air and water. 4. has a high compressibility under intense loading. 5. and is prone to differential weathering. The properties of clay shales in the mining area can be largely attributed to their geologic history. Clay mineral content, lithologic variations and bedding are primarily linked to their depositional history, while secondary features such as jointing, slickened sides, fissures, and faulting are mainly a result of the stress history. Chemical and physical alteration due to exposure and weathering tend to modify these primary and secondary features, creating a zone underlying the eolian sand deposits that has variable engineering properties. From the analysis of core retrieved in the area, occasional zones (usually 2" - 6" in thickness) of stained/altered clays were discovered at depth. These are probably remnants of materials that were, at one time, exposed at the surface. Such layers would be potential zones of weakness, however, because orientations are nearly horizontal, they would not be considered a condition of potential failure by themselves during mining activities. From observations of the Laramie Formation at the Keenesburg Mine (Sec 25, T3N, R64W) and core obtained during exploration activities in Sec. 17,T3N, R63W, the clay-shales exhibit a condition of stress release within the formation. Slickened slides or "micro-faults" have very random orientations and are generally continuous for only a few feet. Joint patterns have also been observed in areas of stress due to minor warping and buckling of the Laramie formation clays. These joint patterns have been traced in the A-Pit highwall at the Keenesburg Mine and can be up to 35 feet in length. Displacements along these near vertical failure planes are typically 0' - .5' , but have been observed to be 5' - 15' in areas of more intense faulting. As a result of weathering, three zones occur within the clay-clay shale sequence of the Laramie Formation. The first zone, which underlies the unconsolidated eolian sands, consists primarily of a disintegrated, oxidized and weathered material generally 0' - 10' in thickness, usually silty and sandy in nature. -9- 870280 The next underlying zone, which is approximately 2-20 ft. in thickness, exhibits moderate disintegration and contains numerous joints and slickened sides. This zone generally has undergone moderate weathering and has become weaker, and is especially unstable in the presence of water. The third and lower most zone has more widely spaced joints and slickened aides. Surface moisture content and thus the degree of weathering is variable and not as extensive in this zone. This material exhibits an overall higher strength than the overlying weathered clay materials. No preferred orientations of slickened sides, joint planes or fault plane surfaces have been determined in the area, however, regional geological structure may suggest strike orientations of larger features (faults, etc. ) in a northwest-southeast direction. Physical and chemical properties of the stratum within the overburden and interburden are found at the end of Section 4.4 Individual Laramie coal beds are often lenticular, do not extend laterally for any great distance and vary considerably in thickness. Areas free of coal were probably channel and channel-margin environments consisting of fine to coarse grained sandstones. Fine, well cemented sandstone boulders encountered in the Keenesburg Mine active pit are representative of channel environments. Light gray claystones (generally massive in the Denver Basin) were deposited in well drained swamps, and light colored silts and clays deposited on levees. The coal, developed from peat layers, along with dark gray, organic rich claystones and clay-shales, accumulated in poorly drained swamps in overbank or flood bank areas. Some coal deposits may have been developed in abandoned channels. The thickest coal beds were formed in more stable parts of the swamp. The Laramie sandstone and Fox Hills sandstone (Laramie-Fox Hills aquifer) lie approximately 210 foot below the expected maximum depth of mining and should not be affected by ash disposal activities. The Laramie formation overlying the Fox Hills Sandstone consists of yellow-brown and gray to blue-gray soft carbonaceous shale and clay-shales interbedded with sand and shaly sand. It contains cross-bedded gray to buff sandstone, which is slightly to well-cemented, and contains coal seams in the lower portion. The Laramie forms the bedrock across all of the mine site and is covered by unconsolidated Tertiary and Quaternary deposits consisting of dune sand, alluvium and terrace deposits dipping slightly westward. All beds below the Tertiary and Quaternary deposits dip slightly to the west. -10- 870280 The formations which are most abundant at or near the surface in Weld County are the Fox Hills and Laramie formations. Refer to the Generalized Stratigraphic drawing on the following page. The Ogallala and Arikee formations are found in the northeast portion of the county. The alluvial materials were deposited in the flood plain of the South Platte River Valley. Terrace deposits formed mainly in the central portion of the county on both sides of the river valley. 4.4.3 Geologic Structures Pre-mine bedrock structures consist of gently undulating bedding planes with a regional dip of 10-30 to the west-southwest, with a north-northwesterly strike. No major faulting patterns exist on the site. Random "fracturing" of plastic bedrock materials exist due to stress release as the strata was unloaded. Several discontinuous randomly oriented shear zones have been encountered during mining. Please refer to Section 4.5.4, Hydrologic Data for cross sections of geology. 4.4.4 Geologic Hazards No geologic hazards are present at the Keenesburg Mine - ash disposal site. Topography of the dump site will be nearly flat, and due to the highly permeable mantle of sand that surrounds the proposed disposal area, erosion potential is minimal . The Keenesburg Mine has not discharged or received run on within its permit area due to heavy precipitation episodes since the inception of the mine in 1980. Although the materials present at the Keenesburg mine ash disposal site have relatively low strengths associated with them, these materials will not be required to meet engineering criteria regarding slope stability and subsidence. -11- 870280 Generalized Stratiqraphic-Column Sec 25 T3N R64W Undifferentiated Eolian sands - V. fine to medium grained buff to brown with yellow-orange arkosic 4800••;•;: unconsolidated sands in upper zone.

This information is combined with studies conducted by McWhorter (Appendix A) during research of the sub-surface water conditions at the present day Keenesburg Mine. 4.5.1 DESCRIPTION OF HYDROLOGY Physiography Weld County lies in the physiographic area known as the Great Plains Region. The general slope of the plain is to the east and southeast. The South Platte River flows through Weld County creating the types of topography that are associated with flood plains, terraces, and uplands. The topography in the north portion of Weld County is gently undulating to rolling. South of the South Platte River valley it is rolling to hummocky. The river floodplain is level to gently undulating. Elevations in the county range from a low of approximately 4,400 feet above sea level at the point of egress of the Pawnee Creek to highs of approximately 6,200 feet above seal level in the northwest portion of the county. Hydrology In addition to the South Platte, important streams in Weld County include the Cache La Poudre River, Vrain Creek, Crow Creek and Kiowa Creek, all of which flow into the South Platte River. Several water impoundments have been developed in Weld County. The larger reservoirs include the following: Empire, Riverside, Milton, New Windsor, Lower Latham and Black Hollow Reservoirs. The rolling ridges of the mining area are primarily blow sand with sage brush and prairie grass for vegetation. In the vicinity of the mine, the area slopes in two general drainage patterns. To the west, the area slopes to Box Elder Creek which has an intermittent stream flow to the north and eventually joins with the South Platte several miles to the north. In the immediate vicinity of the mine site, subsurface flow and surface drainage patterns are to the east. Most mobile subsurface water would flow in an easterly direction towards Ennis Draw. Historically this draw has no surface evidence of water flow, as precipitation is absorbed by the porous surface sands and creates a subsurface flow that supports the salt grass meadows of Ennis Draw. Subsurface flow in Ennis Draw is discharged in Box Elder Creek to the north of the proposed area. Refer to Map 4.6.3 (g) . -24- 8'e 0280 There is no evidence of surface runoff in the vicinity of the site. Essentially all precipitation apparently infiltrates the highly permeable mantle of sand. No water-formed erosional features are evident, not even small rills or gullies. Ennis Draw is a broad, flat-bottomed depression with no observable channel or gully and shows no evidence of the existence of surface flows. The thickness of the blow sand overlying the Laramie is variable but is sufficient to hold a large quantity of capillary water. This observation, coupled with the small annual precipitation relative to the potential evapotranspiration, makes it unlikely that significant recharge to the Laramie through the sand exists. This sand is not known to yield water to wells except in conjunction with the stream deposits in Ennis Draw. Subsurface water occurrence in the coal seam of interest and in the overburden are isolated. Lateral movement of this water is toward the northeast in the mine area and may discharge into the sands and stream deposits in Ennis Draw to the north and east of the mine site. Observations of the coal seam indicate only a saturated thickness of 1 to 2 feet at an elevation well below that of the piezometric water surface of Ennis Draw. This suggests that water occurrence in the coal seam is confined and no hydrologic connection exists between the coal seam and Ennis Draw. Ground water in neither the coal nor overburden is known to provide a water supply for any purpose in the vicinity of the mine. Refer to Piezometric Surface Map, Map 4.6.3 (e) Subsurface Water Hydrology Four subsurface water systems can be identified to exist in the vicinity of the project site. In order of occurrence (top to bottom) they are situated as follows, 1) wind blown sand and fluvial deposits in and adjacent to Ennis Draw, 2) weathered bedrock (transition) zone consisting of silty clays and sands, 3) unweathered, overconsolidated clays and clay shales, mud stones, clay stones, coal and minor sandstones of the Laramie Formation (excluding the lower Laramie sands) and 4) the Laramie-FoxHills aquifer (which includes the lower Laramie and Fox Hills Sandstone formations) . Information regarding subsurface water occurrence is summarized as follows (refer to cross sections on following pages, where aquifer systems are labled by number) : -25- 870280 1 ) Surficial - Near Surface Water Occurrence: Unconsolidated fine to coarse grained sands w/occasional 1/8" to 1-1/2" gravels; silty, clayey. Windblown sands cap these deposits. Subsurface water occurrence as influenced by the Ennis Draw paleo channel/bedrock structure is restricted to the eastern 1/3 of Sec. 25, T3N, R 64W, 6th PM. Subsurface water flow in Ennis Draw is predominantly SE to NW. This unconfined (water table) aquifer, inclusive of the eolian sands adjacent to Ennis Draw, varies from 0 ft. - 30 ft. in thickness. 2) Bedrock (Laramie-overburden) Water Occurrence: Weathered silty clays and sands that overlie unweathered bedrock. Subsurface water resides in this transition zone between the overlying sands and underlying clay bedrock. Ground-water flow is to the northeast across the mine site and is largely controlled by the top of bedrock which also slopes to the northeast. Preferential zones of water migration (higher relative permeability) exist in the weathered bedrock materials. The occurrence of subsurface water is largely unconfined in nature, however, there is some information suggesting that this system can be locally confined. Thickness of these zones is approximately 0 ft. to 20 ft. However, silty clay may cap gravels on the western flank of Ennis Draw. 3) Unweathered Bedrock (Laramie-Overburden) Water Occurrence: Overconsolidated clays and clay shales are the predominant lithology. No flows have been observed from these materials as permeabilities are very low and resist vertical and horizontal migration of subsurface water from the overlying weathered bedrock. However, very isolated zones of silty, sandy rock types representative of channel type environments may produce small quantities of water ( .5gpm) . The occurrence of water in the coal seam (thickness=7 ft. ) is restricted to the lower 1' -2' , and appears only as visible surface moisture. Subsurface water in the unweathered bedrock (thickness = 45-70 ft. ) and the coal seam is considered to be confined and separate from one another. 4) Laramie-Fox-Hills Aquifer Water Occurrence: These deposits consist of massive fine grained sands and siltstones. The No. 7 coal seam to be mined is separated from the underlying Laramie and FoxHills sandstone by 100 to 200 feet of Laramie clays and clay shales. The Laramie-FoxHills aquifer will not be affected by the ash disposal operation. Thickness of this confined aquifer is approximately 35' . 870280 -26- Geohydroloqv Twenty-one existing wells were utilized by Colorado State University for the purpose of studying the geohydrology of the surficial, Laramie coal aquifer. In addition, one well was constructed as part of a test dewatering effort of the fluvial sands in the shop area and two wells were constructed into the Fox Hills Sandstone to supply water for the project. The location of all wells in the study are noted on Maps 4.6.3 (e) and 4.6.3 (g) . Several types of aquifer tests were conducted on the teat wells. The Ennis Draw deposits possess tranamissivities of 14,300 to 19,700 gpd/ft. ; the Laramie shale overburden, 2.5 to 34 gpd/ft. ; the coal, 1 .8 to 236 gpd/ft. ; and the Fox Hills Sandstone, 1,630 to 2,340 gpd/ft. (See Appendix A, McWhorter, page 18) . 4.5.2 Upper Most Aquifer Aquifer Extent and Piezometric Surface All the above described aquifers with the exception of the Ennis Draw fluvial subsurface water system are present under the entire area of the proposed project site. The blow sand and fluvial sand thickens eastward across the project to its greatest thickness in Ennis Draw. The bedrock aquifers are relatively uniform in thickness and dip westward into the Denver Basin. The water table aquifer of Ennis Draw generally follows the fall of the land surface toward the north. The piezometric surface of the Laramie Shales slopes toward the northeast (Appendix A, McWhorter, page 27 Map 4.6.3 (e) . The coal piezometric surface possesses a northwest/southeast oriented divide (Appendix A, McWhorter, p. 28) . Both of the latter two aquifers are believed to discharge in the lower depths of Ennis Draw. 4.5.3 Existing Uses/Domestic Wells Existing uses of ground water in the project area are for domestic supply and livestock watering. Data collected from 24 wells (Appendix I-1, McWhorter, p. 100) indicated that all ground-water for such uses are derived from the Ennis Draw alluvium and the Fox Hills Sandstone. Water likely is not utilized from the Laramie shales or coal due to its poor quality. Refer to Appendix D-1 for map showing locations of wells in the vicinity of the extension area. There are no water supply intakes, ditches, reserves or other surface water bodies within a one mile radius of the affected area. In addition, there are no irrigation ditches, or constructed or natural draws within the proposed extension area. -27- 870280 Surface Water The mine is located adjacent to Ennis Draw, a tributary to Box Elder Creek which flows into the South Platte River near Kersey, Colorado. There is no evidence of surface runoff in the vicinity of the site. Essentially all precipitation infiltrates the highly permeable mantle of sand. No water-formed erosional features are evident, not even small rills or gullies. Ennis Draw is a broad, flat bottomed depression with no observable channel or gully and shows no evidence of the existence of surface flows. 4.5.4 Hydrologic Properties Any possible effect of ash disposal on the subsurface waters of Ennis Draw will be significantly reduced, as the area of proposed ash disposal in A/B Pit will be above the mining ground water table. Instantaneous pit inflows from the Laramie Formation had been expected to range from 20+ to 130 + gpm, depending upon the number of pita open and duration since opening. (McWhorter, 1978) . It was also estimated that piezometric drawdowns in the Laramie Formation due to presence of the mine will be extended no further than 0.5 miles. The quality of ground-waters after ash disposal is expected to be comparable to water resident in the Laramie shales and coals - no appreciable degradation of water quality is anticipated as Laramie ground-water passes through spoils or leaching through ash enroute to the Ennis Draw subsurface water system. Mine operations have remained 100' west of Ennis Draw. This was based on recommendations presented in the hydrological report relating the ability of ground-water to move through the overburden. Mining operations have not disturbed overburden materials (clays and clay shales) and therefore, subsurface waters are confined and hindered from recharging the eastern portion of the ash disposal area. During the duration of mining in A-Pit since the opening of the mine in 1980, minimal to non-existent pit inflows have been encountered. The high estimates for pit inflow had been based upon information at the time prior to mining. There estimates were based on: 1 . A high assumed saturated thickness of the overburden 2. The ability of the overburden to transmit water 3. The overall extent/presence of water in the overburden -28- 870280 As mining progressed, pit inflows estimated before mining, were not encountered. This suggests that the three factors listed above can be down graded, primarily because saturated thickness of the overburden was estimated to be 65 ft. , when in reality it is about 5' -1O' maximum, and in some areas, zero. Subsurface water exists in the lower portion of the coal seam presently being mined and, as isolated, perched conditions in the overburden. Ground-water in neither the coal nor overburden is known to provide a water supply for any purpose in the study area (McWhorter 1980) . This may be partially due to the overall inability of the coal or overburden aquifer to discharge water to wells completed in them. Ash disposal will be restricted to zones above pre-mine ground-water levels. In the transition zone between the contact of eolian sands and weathered-bedrock clays, lateral movement of this water is generally toward the north-northeast. The saturated thickness of these silty-clayey fine grained sands immediately above the clay bedrock is from 0-10 ft. , with subsurface water occurrence controlled largely by the configuration of the top of clay and zones or channels of increased permeability. Hydraulic conductivities are estimated to be 3 gallons/day/£t2 in these zones. Ground-water conditions would be considered unconfined. However, locally confined conditions may exist in the less weathered portions of overburden clays and silts. Instantaneous discharge rates estimated for the entire length of an excavated face is between 1 to 10 gpm, with maximum total, accumulated discharge rates of less than 5 gpm (excavated face = pit length = 2700 ft. ) . The clays and clay-shales situated beneath the weathered zones do not produce inflows to the pit. They are highly compacted materials in their undisturbed state and highly compressible with a high plasticity in their disturbed condition. The vertical and horizontal permeabilities of these materials are almost negligible. The lower portion of the coal seam (bottom 2 ft. ) occasionally discharges small amounts of ground-water into the coal void just after mining. Ground-water production rates from an excavated coal face 60 ft. by 8 ft. have not exceeded 1 gpm. Occurrence of water in the coal seam appears to be somewhat restricted to structural depressions of the coal seam. Ground-water production rates do not increase significantly as mining approaches the western boundary of Ennis Draw. This suggests that the coal seem has very low permeability (hydraulic conductivity estimated to be .23 or 23 gpd/ft2 - 29 gpd/ft2, (McWhorter) and/or the coal seam does not have lateral continuity to the fluvial deposits of Ennis Draw. Since the coal is considered to be a confined aquifer, and is not fully saturated, it would be reasonable to conclude that the coal seam does not have hydraulic conductivity with the Ennis Draw subsurface water system and associated stream deposits. -29- 870280 Please refer to the following cross-sectional views depicting geohydrological conditions existing in the second five year permit area. These cross-sections show the relationships between the second 5 year extension area and other ground-water systems in the area. No surface water features exist in the area. 4.5.5 Ash Disposal Ad-iacent to Alluvial Valley Floors and Flood Plains The proposed ash disposal site boundary is located on wind-blown sand deposits. Within the ash disposal site boundary there are no streams of any kind. The permeability of the blow sand is evidently sufficient to prevent overland runoff except possibly for very intense rainfall events. There is no evidence of channels or even rills that would be indicative of surface runoff. The absence of any streams or channels within the life-of-mine boundary is taken to mean that no lands within that boundary qualify as alluvial valley floors or flood plains. As stated in the report of hydrologic investigations, drawdown of the piezometric surface in the Laramie formation probably will not extend beyond about 0.5 miles from the pit during mining. The transient drawdown created during mining will eventually dissipate and a more-or-less steady post mining flow pattern will develop. If the transmissivity of the backfilled mine area should be identical to the pre-mining values, the post mining flow pattern and ground water discharge would be unchanged from the pre-mining situation. In this case the maximum extent of the affected area would be on the order of 0.5 miles from the life-of-mine boundary. The extent of the actual affected area can be shown by comparing the piezometric surface map presented in this permit to the piezometric map found in the original permit application for the Keenesburg Mine (Map 4.6.3) . The maximum distance the piezometric surface has been affected by mining is 4300 feet southwest from the center of the presently mined area. Also note in Map 4.6.3 (e) of this document that recharge of the spoil material appears to be from the west-northwest. Shown in Map 4.6.3 (e) is a gently sloping hydrologic gradient from the northwest to the southeast to the approximate center of the mine. This would indicate that higher values of transmissivity/permeability exist in the spoil materials. -30- 870280 LOCAL i,)N OF CROSS-SECTIONS A-. , B-B' KEENESBURG MINE AND VICINITY, WELD COUNTY, CO R.64W.

Ennis Draw, which lies immediately on the east of the boundary, does not hold a stream. Ennis Draw is a relatively broad, flat, topographic low in which no stream channel is defined. No evidence of a presently existing perennial, ephemeral, or intermittent stream in Ennis Draw has been observed. There is subsurface evidence that a stream once existed in the draw, but these deposits have been covered over by the existing wind blown deposits. As shown in Map 4.6.3 (e) , the subsurface water system of Ennis Draw has been effectively isolated from the mining activity presently being conducted adjacent to the draw. There has been none, nor is there anticipated to be, a significant impact to the ground-water levels in this area. Box Elder Creek is located about 3 miles west of the proposed ash disposal site. At this time, however, it is not anticipated that ash disposal will progress far enough west to effect ground-water flow to Box Elder Creek. As explained in the report of hydrologic investigations, the quality of post ash disposal activities on the ground-water is not expected to differ substantially from that which now exists. (See Water Quality Data, Section 4.5.7, Appendix B. Ash test results and Water Quality, Appendix C) . Therefore, neither the quantity nor quality of waters associated with Box Elder Creek or Ennis Draw are expected to be affected. In any case, the discharge through the life-of-mine area is very small . The ground-water discharge through the area was previously estimated to 5.4 ac-£t/yr or only 3 gpm, however, based on observations of the active pit area, this discharge rate through the area may be high. 4.5.7 Ground-water Quality and Monitoring Since the initiation of the formal ground-water sampling program in January 1982, twenty quarters of sub-surface water quality information has been collected from monitor wells in and around the Keenesburg Mine. This ground-water monitoring program has delineated baseline conditions concerning ground-water movement and quality in and around the active operations area. The results obtained from data collected in the field and from comprehensive water quality analysis indicate that surface and ground-water quality has not been impacted from the natural pre-mine conditions. In addition, major ground-water movement patterns have not been influenced or interrupted by mining activities. -34- 870280 Sampling of subsurface water from monitoring wells was conducted using a submersible pump system. The major components of this system include a Grundfas 1/3 HP stainless steel submersible pump and 1" diameter nylon reinforced discharge tubing equivalent to "Tygon" type tubing. The equipment is powered by a truck mounted electrical generator. The discharge capacity of the pump is approximately 5 gpm. Two casing volumes are removed prior to the sampling of discharging well water. However, some of the wells, particularly SMW-1 and DH-172 have very slow recovery rates. In these instances, one casing volume is evacuated prior to sample collection from such wells. After water samples are collected in appropriate bottles containing the required preservatives, they are kept cool in an insulated container. Samples are delivered within several hours to the laboratory where they are filtered and prepared for analysis. At the well site, readings of pH, EC, temperature (0C) and water level are recorded. Water levels are measured with a tape measure from the top of the casing and recorded prior to pumping. Water Quality Water quality data has been accumulated from all aquifers (Appendix A, McWhorter, p. 29 thru 35) . Generally, the waters in the Laramie Shales and the target coal would be unacceptable for most uses. The total dissolved solids concentrations were from 1500 to 7000+ mg/l. In addition, the sodium absorption ratios (SAR) were 10 to 18, making the water mostly unsuitable for irrigation. The Fox Hills water possessed TDS of 650+ mg/1, while Ennis Draw ground-water TDS is 750-1000 mg/l . All water quality data collected to date in the vicinity of the ash disposal area is summarized in Appendix C. Electrical conductivity is measured in units of micro Siemens per cm. Since the conductivity meter used measures the electrical conductivity at the sample temperature, the reading must be converted to a specific conductivity by applying a temperature correction and cell correction. The cell correction or cell constant can vary from meter to meter or, for the same meter, can vary with time. For this reason, a cell constant is checked on a regular basis and is determined by comparison of the conductivity of a standard .01M KC1 solution at a given temperature to published data. A map showing the location of the monitoring wells is presented in 4.6.3 (e) . -35- 870280 Eight wells are to be used to monitor sub-surface water conditions in and around the Keenesburg Mine ash disposal site. The Table below summarizes well designation, reference elevation from top of casing and aquifer monitored.

Leach tests indicate that no toxic fluids will be produced and the chemical composition of the ash is better then the enclosing overburden materials. The final surface will be covered with not less than 2' of topsoil material which will be graded, seeded and irrigated. Although permeability of this material is quite high, rainfall and runoff are quite low and leaching can only improve the chemical characteristics of the enclosing sands and clays. Approximately 2,000 c.y. of cover material will be required for each six month site or between 28,000 and 68,000 c.y. For the life of mine. This is only 2% of total topsoil required which is readily available in stockpiles and in new mining areas that are periodically opened. The proposed sites are formed by depressions in the dragline spoil windrow where a new cut is started. Since the dragline casts to his right or left in an area from where the overburden is removed, there is always a deficiency of spoil at which ever end of the pit the dragline started its cut. It is into this type of depression or occasionally a valley between two spoil piles that our present solid wastes are being dumped. This elevation will vary from a low of 4775 up to 4830. Present spoil water table is at 4730 and is monitored every month. These sites will be verified for construction quality by John Althouse, Colorado Professional Engineer 5380. 4.6.3 Appropriate maps are presented on the following pages. 4.6.4 Refer to Appendix A, McWhorter Report, for complete construction details and Section 4.5.7, Ground-water Quality and Monitoring. -37- t_':"~E:? o 4.7 OPERATIONAL DATA 4.7.1 Operational Qualifications Coors has no previous experience in operating a solid waste disposal site except for daily disposal of solid waste generated in the normal course of mining. This waste has always been placed in the mined out pit above the ground-water table and at least 4 feet below approximate original contour. No citations for this particular phase of the operation have ever been written. Larry Campbell is the Mine Manager and Resident Agent. John Althouse is the Professional Engineer. Both have authority to take corrective action and this will be done as quickly as possible when necessary. This action will involve cessation of all ash dumping until the problem has been corrected and if necessary, the removal and relocation of the material that has caused the problem. 4.7.2 Hours of Operation Coal trucks start arriving at 3:00 A.M. and finish loading at 11 :00 P.M. There are 42-48 loads per day. Four of these will be back-hauling ash so the dump area will be open during these hours. These truck drivers load their own trucks so they will be expected to unload their ash loads also. If they need assistance, radio contact is available with the production foreman on each shift. 4.7.3 Waste Volumes A mixture of 50 c.y. of flyash and 50 c.y. of bottom ash is estimated to be the maximum back haul each day. 4.7.4 Personnel The dragline operator with the assistance of the dragline oiler and dozer operator will construct the dump site. The truck drivers will dump their ash loads. Various mine personnel, but mainly the janitor, will dump paper, wood and metal at the same site. 4.7.5 Equipment The 17 c.y. Marion dragline and a Caterpillar D9L tractor will be used to construct the site. Other wastes are picked up in dumpsters by a Case 680 CK and hauled to the site. The present 25T Tempte-Beal belly-dump coal trailers may be tried as ash haulers. More likely a rear-dump type highway hauler (18 wheel) to carry 25T. of ash will be acquired. -42- 870280 4.7.6 Recozs Records will be kept on the volume/day of incoming ash. Quarterly water quality results will be kept for all monitoring wells. No wells are being monitored for explosive gas. All wells are less then 180' deep. Since all sites are rough constructed and temporary, compaction tests and soil tests will not be taken. Variations from approved procedures will be documented. There will be no special wastes received at the site. 4.7.7 Disposal Cells There will be no disposal cella within a given site since all sites are small and distinct from each other so that they can be monitored separately. It is estimated that at least 40' of overburden material will be maintained between the site bottom and the spoil water table. The slopes of the site will be 1 :1. The ash is expected to stand at 1:1. The finished sites will be reclaimed at 5X or less. 4.7.8 Cover Application The daily delivery of 100 c.y. of ash will only require 10 c.y. of sandy clay to cover to a depth of 6" . Since the ash material will contain 30X moisture, fugitive dust is not expected to be a problem. In fact the dumping of the ash over other wastes such as paper, wood and metal will reduce the blowing of paper which is a very minor problem at present. This material can and will be covered with moist sandy clay (overburden material) if fugitive dust is a problem. 4.7.9 Fencing The mine is completely enclosed by fencing. Most of this fence is four-wire barbed wire, 48" high, the rest is electrically charged - one wire. The mine map under 4.6.3 shows the detail on fencing. 4.7. 10 Nuisance Condition The hole into which present trash is dumped is generally deep enough (20' -40' ) to shield the trash from being blown out of the hole. We have more trouble with open dumpsters in the shop area having trash blown out of them. When this happens the trash is picked up by hand. We have not had nor expect to increase the chance of having dust, odor, vector or burning problems when ash is added to the solid waste disposal plan. 4.7. 11 Open Burning Open burning is not allowed and is not done. Most of the waste will not burn. If fire should start it will be extinguished immediately by covering with overburden material . -43- 870280 4.7. 12 Windblown Debris Since most of the trash will be wet ash this should improve any present windblown problems. Since only two or three dumpsters containing 50% paper are dumped each week, the daily ash dumping will quickly cover this mine trash and help to alleviate any windblown problem that might exist. Prevailing winds are from the west and northwest. The nearest habitation downwind is at Roggen - seven miles east. No litter has ever been observed east of the present east side fence line which is between 1/2 to 2 miles downwind from the dump sites. No special provisions are provided for not dumping on windy days. Coors will make sure that anything that could be airborne will not be dumped on a windy day. Fencing will remain as described before and depicted on Map (i) , 4.6.3. The working face could be as wide as 160' but as soon as a given part of the site is filled, the ash will be covered with overburden material in preparation for reclamation. Depending on weather and other physical conditions the face will vary from 50' to 160' wide. 4.7. 13 Conceptual Plans In the event of a worst case situation as described here, Coors will immediately cease ash hauling and/or refuse disposal until the problem has been corrected. The Department of Health and The Mined Land Reclamation Division will be so notified. New monitoring wells will be drilled immediately as well as the installation of lysimeters if appropriate. Interrupter ditches and sumps may also be dug. It is inconceivable that any surface water problems could occur since general land gradients are away from the nearest surface water which is four miles to the west. Since spoil monitoring wells are installed and other wells on and off the property are sampled quarterly, it is also inconceivable that any ground-water problems could occur due to this ash dumping, since the ash produces a better leachate than the disturbed overburden. Coors suggests that ash will have a beneficial effect on the quality of the newly established spoils ground-water table and reduce the risk of ground-water contamination due to mining. _44_ 870280 4.7. 14 Water Water for personal use is drawn from a Laramie-Foxhills well at a maximum 80 GPM. Another Laramie-Foxhills well is available for dust suppression at 90 GPM. A fire protection well is maintained as well as numerous shallow sumps in various parts of the mine. No needs for water in the ash pits are anticipated. 4.8 CLOSURE DATA 4.8. 1 Maintenance Under the terms of the present permit Coors is required to return all areas of the mine to approximate original contour, topsoiled, seeded and irrigated. Sediment ponds will be maintained until the very end to control any runoff. No streams of any sort are on the property. Litter will be picked up by hand as at present. Final reclamation and abandonment should be completed by the end of the following seeding season. (5/15) . 4.8.2 Monitoring Monitoring of ground-water will continue at the ash disposal area until, upon the finding of the Mined Land Reclamation Division, the monitoring wells/program are no longer needed for the intended use and no adverse environmental or health and safety conditions exist. 4.8.3 Final Contours A post-mining contour map is provided under the map section 4.6.3.

The Larimie-Foxhills formation, the most important aquifer _ in the area, is more than 200 ft below the coal seam proposed to be mined. No effects of mining on the Laramie-Foxhills aquifer are anticipated. Surface runoff in the area is essentially non-existent under present conditions. This is not expected -to change provided that three or more feet of the existing blow sand are placed over the spoil in the reclam- ation phase. The target coal seam and the Laramie overburden are hydraulically independent aquifers. The coal seam is a confined aquifer but waters in the overburden are only locally confined. Flow of ground water through the coal seam is negligible as the transmissivity of this aquifer is extremely small. Groundwater flow in the overburden is toward the north- east. Approximately 5.4 acre-ft of groundwater per year are discharged from the leasehold area. This flow apparently enters the blow sand and • stream deposits associated with Ennis Draw. The source of this flow is external to the study area and enters the project area by lateral flow. Recharge of the overburden aquifer in the study area is believed to be essentially zero. The water in the overburden aquifer is of poor quality, the dissolved - solids concentration exceeding 7000 mg/1 with a ;odium-adsorption-ratio greater than 10, Probably the only viable use of the water in the over- burden is for dust control or similar purpose. Waters contained in the 8702849_ 1 2 blow sand and stream deposits associated with Ennis Draw exhibit a much better quality, the dissolved solids concentration ranging between 750 and 1000 mg/1 . There is, apparently, subsurface flow from the south in Ennis Draw which is sufficient to•dilute the small quantities of saline inflow from the Laramie. The quantities of pit inflow were estimated using a succession-of- steady-states computation procedure, together with the mining plan and the hydraulic properties of the aquifer as determined by aquifer tests on the proposed mining site. The peak inflow rate is estimated to be some 130 gpm and will occur when pit B has reached its maximum length of 3000 ft. The inflow from both pits A and Bare. included in this estimate. 'The estimated peak inflow is believed to represent a maximum 1 that can reasonably be expected to occur. Several aspects of the com- . putation tend to cause the estimates to error on the high side. The quality of the inflow should not be substantially different from the quality of existing overburden waters. The distance from the pit to points where the piezometric surface in the overburden will remain undis- turbed is approximately 0.5 miles. Therefore, at any time, drawdown of • the piezometric surface in the overburden is not expected to extend more than about 0.5 miles beyond the boundaries of the area to be mined. Unless specifically avoided, the pit will apparently intersect and I . cut through the stream deposits and blow sand associated with Ennis Draw in one limited area. Inflow to the pit from these deposits may equal or exceed the inflow from the Laramie. Drawdown of the piezometric surface ]— in these deposits caused by mine inflow can be expected to be substantial . is It is recommended that special care be taken to protect the integrity of the ground waters in the blow sand and stream deposits associated with 870280 f.. 3 Ennis Draw. Adverse effects on these waters should be minimized by restricting mining operations so that the stream deposits in the old Ennis Draw are not intersected or by protecting them by a compacted shale trench. It is believed that mining will have no appreciable effect on the hydrplogic budget of the area, and that water levels in the mined area and in the Ennis Draw deposits will recover to approximately their original levels following the end of mining. Provided that care is taken to min- imize hydraulic communication between the Ennis Draw deposits and the mined area, there should be no significant long term adverse effects of mining on the quality, quantity, or distribution of water resources in the study area. 4 870280 4 I. Introduction The Department of Agricultural and Chemical Engineering, Colorado State University, agreed by contract with the Adolph Coors Company of Golden, Colorado to make a preliminary study of the water resources in the vicinity of a possible coal strip mine site located in sections 25, 26, .35 and 36 (approximately), T3N, R64W, Weld County, Colorado. • The objective of this study was to evaluate the water resources at the potential strip coal mine site relative to the following concerns: .a. Quantity of existing water resources, b. Quality of existing water resources, c. Potential impacts of mining on quantity of water, d. Potential impacts of mining on quality of water, e. Quantity and quality of mine inflow. To achieve this objective 21 wells were drilled in the study area to provide a means for identifying aquifers, measuring piezometric sur- face elevations, measuring the transmissivity and storage coefficients and collecting water samples from each aquifer. The report contains a summary of the data collection procedures, analyses of the data and the conclusions derived in the course of this investigation. II. General Description of Hydrology and Geology A. Climate The climate of the study area is characterized by low relative humidity, cold winters and modestly hot summers. The mean annual temper- _ ature as recorded at Greeley and Fort Lupton is about 48°F. From 1952 - to 1976 the average annual precipitation ranged from 12.08 inches at Fort Lupton to 12.28 inches at Greeley. The maximum monthly precipitation �s7� �" ' normally occurs during May; the minimum normally occurs during January 5 in the form of a light, dry snow. About 52 percent of the annual pre- cipitation falls during April , May, June and July and only about 13 per- cent is received during November, December, January and February. The mean monthly precipitation during the period of record for both stations is shown graphically in Figures 1 and 2. B. Geology Rocks of the Precambrian to early Cretaceous age underlie most of the area at great depths. These deposits are overlain by the Pierre shale and generally dip westward. The Pierre shale consists of. a thick sequence of fossiliferous marine shale, silt, and clayey sandstone, which contains numerous calcareous concretions. The upper part of the formation is transitional with the overlying Foxhills sandstone. "The Foxhills sandstone is yellowish-brown calcareous marine sand- stone interbedded with dark-gray to black sandy shale and some massive white sandstone. The zone of contact with the underlying Pierre shale consists of gray sandy shale and shaly sand. The overlying non-marine Laramie formation is also transitional , and contains some lignite and other non-marine beds which occur in the upper part of the Foxhills. The Laramie formation consists mainly of yellow-brown and gray to blue gray soft carbonaceous shale and clay interbedded with sand and shaley sand. It contains some crossbedded gray to buff sandstone, which is slightly to well cemented, and coal , especially in the lower part. ! The Laramie formation forms the bedrock across much of western Weld 1i County. Much of the bedrock is covered by unconsolidated Tertiary and Quaternary deposits. The unconsolidated deposits consist of dune sand, 87028o 6 • • • 3.O- ' N • - t 2.0 C O ck • V 1•y • • . 4 a Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec • Figure 1.

Only the formations of Late Cretaceous and younger are of interest in this report. In particular the sand overlying the Laramie formation, stream deposits near the east boundary of the site, the Laramie above u the .coal and the coal itself are of interest. These formations are exposed or underlie the project area at relatively shallow depths. Since the Laramie-Foxhills aquifer is confined and exists more than 200 ft below the coal seam to be mined, it is expected that it will not be affected by the mining of coal in the overlying Laramie and was, therefore, not of major concern in this study. C. Water Resources J Most of the residents in the vicinity of the study area depend on privately owned wells for domestic and livestock purposes. Data collected on 24 wells indicate that 7 of these wells, located in the close proximity of the leasehold, penetrate the stream deposits overlying the Laramie in a broad depression known as Ennis Draw. The remaining 17 wells are apparently completed in the sandstone beds of the Laramie-Foxhills. These wells are generally 4 to 6 inches in diameter. Most of the domestic wells are equipped with a submersible pump driven by an electric motor. Wind- mills power many of the stockwells. The average yield of these wells is about 2 gpm. There is no evidence of surface runoff in the vicinity of the site. Essentially all precipitation apparently infiltrates the highly permeable mantle of sand. No water-formed erosional features are evident, not even small rills or gullys. Ennis Draw is a broad, flat-bottomed depression with no observable channel or gully and shows no evidence 87023,0 8 of the existence of surface flows. The thickness of the blow sand overlying the Laramie is variable but is sufficient to hold a large quantity of capillary water. This observa- tion, coupled with the small annual precipitation relative to the poten • - tial evapotranspiration, makes it unlikely that significant recharge to the Laramie through the sand exists. This sand is not known to yield water to wells except in conjunction with the stream deposits in Ennis Draw. Ground water exists in the coal seam of interest and in the over- burden. The saturated thickness of the overburden is some 65 ft. Lateral movement of this water is toward the northeast in the study area and undoubtedly discharges into the sands and stream deposits in Ennis Draw to the north and east of the project site. Ground water in neither the coal .aor overburden is known to provide a water supply for any purpose in the study area. • III. pre-hlinin Subsurface H drolo and Water e in Detailed Stud Site A. Geology. A map of the study area is shown in Figure 3. The study site covers about six square miles and includes Sections 25. 26, 35, and 36. The land is gently sloping to the northeast toward Ennis Draw which is located on the eastern boundary of the study area and generally runs in a north- south direction. A Preliminary look at geophysical logs suggested that it would be impractical to identify individual aquifers in the overburden sequence. It was , therefore, decided to treat the coal , overburden and the over- lying sand as individual potential aquifers.

On the average, the deposit is feet thick and dips gently eastward. The overburden is•composed mainly of sand, clay, shaly sand and crossbedded sandstone. The thickness of this deposit decreases in an ' easterly direction from 146 feet at the western boundary of the study area and practically vanishes at Ennis Draw. In Ennis Draw the overburden material has been replaced by stream sediment as shown in Figure 4. - The maximum thickness of the coal seam is approximately 8 feet and occurs toward the center of the project area, but subsequently thins to about 2 feet at the north and east boundaries. The depth to the coal seam from the ground surfaca varies between 170 feet at the western boundary of the site to approximately 70 feet at Ennis Draw as shown in Figure 4, "Although the overlying sand deposit is highly permeable it does not contain water and, therefore, cannot be considered an aquifer. Both the coal and the overburden are water bearing formations and are, there- fore, the only aquifers considered in this study. B. Characterization of Hydraulic Properties of Aquifers Twenty-one wells have been constructed for the purposes of the hydrologic study. The locations of these wells are shown in Figure 3. The drilling and testing program was designed to treat the coal and the overburden as individual potential aquifers. A total of 10 wells were constructed to provide hydrologic data on the coal seam. Wells numbered 61 , 116, 132, 137, 162 and 171 are all 5-inch diameter wells completed in the coal . Figure 5 shows the typical construction details for these wells. Four additional wells numbered 60, 62, 134 and 138 are 2-inch diameter wells constructed for the purpose 870230 11 0 N O O n O • aaIII. • W ' . . o N` • ' ir :f w.y r A A I . a in In • a C, n 1 a s c y I 01 e III 1 tCI a �: I L . 1I 1 1J I a.+ g -111 '2 II, •1� _ 0 • 1 1 X .. • F 1 in s X Y— E I n • 0 4-1 1 I Y N 1 N N ' O L. n , I U H { � I y � .• I L F I a I �' I :o i 5 £ ii:i _o I a 1 u io 11 = , "I: • i: -Si- • I n _-: 1 • ILI I I • 870230 - 12 Z� -....c. . - Ground Surface t 10 ^.

Wells with 5-inch diameter completed in the overburden are numbered 96, 117, 122, 133, 163 and 172. Wells numbered 118, 119, 173 and 174 are . 2-inch diameter wells completed in the overburden as drawdown observation wells. Typical well construction of the 5-inch and 2-inch wells completed , in the overburden is shown in Figures 7 and 8. Well number 97 is completed in both the overburden and the coal as shown in Figure 9. Schematic drawings of the remaining wells are contained in Appendix A. Seven separate determinations of the transmissivity of the overburden were made. The wells involved in these•determinations were 172, 122, 117, 118 and 119. Two determinations of the storage coefficient were made by measuring the drawdown in wells 118 and 119 in response to pumping from • well 117. Similarly, eight determinations of the transmissivity of the coal seam were made by running various tests on wells 137, 116, 61 , 62, and 60. Two values of the storage coefficient in the coal seam were estimated from drawdown data in wells 60 and 62 in response to pumping from well 61. The results of these tests are summarized in Table 1 .

Before initiating the test the static level in the well was recorded. The residual buildup of piezo- metric head was then observed in the injection well itself at selected intervals of time until the test was completed. b. Drawdown Test - Immediately before starting the pump, the water levels in the observation wells and in the pumped well were measured to determine the static water levels upon which all drawdowns were based. The instant of starting the pump was recorded as the zero time of the test. If the initial discharge was in excess of the continuous discharge, the valve in the discharge pipe was then adjusted so as to maintain the discharge as constant as possible throughout the test period. Water levels in the observation wells and pumping well were measured at selected intervals of time until completion of the test. c. Recovery Test - When the pump was stopped after running the drawdown test, the drawdown and time at which it was shut down were recorded. Measurement of water level was immediately initiated in the pumped well and in the observation wells where appropriate. The same procedure and time pattern was followed as at the beginning of the draw- down test. As in the drawdown test, the time and water level are recorded for each measurement.For the slug test analysis, the residual buildup in well 116 was } plotted on coordinate paper against the corresponding values of lit as shown in Figure 10.

The source of a portion of the pump discharge was the water standing in the well bore. Thus, the pumping rate from the aquifer itself was substan- tially less than the pump discharge. The equations used for analysis of the data do not account for this discrepancy. The effect is to cause the .transmissivities derived by this procedure to be greater than actually exist. Therefore, the transmissivities reported in Table 1 should be regarded as upper limits, the actual values being somewhat smaller. In any case, the values shown in Table 1 are very small , indicating very poor aquifers. In fact, neither of the zones tested would be regarded as aquifers at all in most contexts. • The values of storage coefficient reported in Table 1 suggest that both the coal and overburden are confined aquifers. We are fairly con- fident that the coal seam is, indeed, a confined aquifer with little or , no communication with the overlying waters. Evidence to this effect is provided by the fact that the piezometric surface for the coal seam, throughout the project area, is lower than the piezometric surface for the overburden. This observation is depicted in the cross-section in Figure 4. Pump test data in the overburden provide an estimate of storage coefficient on the order of 10-4 in the vicinity of wells 117, 118 and 119. This value certainly suggests that the overburden aquifer is con- fined at this location. Furthermore, the static water levels in wells 117, 118 and 119 stood well above the interface between the Laramie and the overlying blow sand. This observation supports the conclusion that L the overburden waters are confined in the vicinity of these wells. Comparison of static water levels in the remaining overburden wells with 870230 -: 25 the elevation of the top of the Laramie are presented in the cross-section in Figure 4. It can be observed that the water table profile lies beneath the top of the Laramie. This suggests that the overburden aquifer is uncon- fined over the rest of the project area. C. Piezometric Surface Water surface elevations in 23 wells were measured relative to a cannon datum. The data obtained is summarized in Table 2. Contour maps of the piezometric surface were prepared for the overburden and coal aquifers and are presented in Figures 13 and 14 respectively. The piezometric surface in the overburden is relatively featureless and slopes toward the northeast at a gradient of about 0.006 as shown in Figure 13, indicating that the ground water in the project area dis- charges into the subsurface deposits in Ennis Draw. The discharge rate, Q, through the boundaries of the leasehold was computed on the basis of Darcy's Law which can be expressed as: Q = TIL where T is the transmissivity, I the hydraulic gradient and L the width of flow. Using an average transmissivity of 7 x 10-3 ft2/min, a hydraulic gradient of .006 and an average flow width of 6000 feet, the discharge rate through the eastern boundary of the study area was estimated to be approximately 3 acre feet per year. In a similar manner the discharge through the northern boundary was computed to be about 2.4 acre feet per year. This gives a total discharge from the project area to Ennis Draw of approximately 5.4 acre feet per year. The piezometric surface map in the coal depicts a ground water divide along wells 134 and 116 as shown in Figure 14. East of the divide the S₹`�+2SO = 1 26 Table 2.

Ground water discharge from the coal seam toward Ennis Draw was estimated to be about 0.1 acre foot per year. This discharge is very small . and coal aquifer discharge was not considered further in our analysis. Continuous water level recorders have been installed on wells 61 , 122 and 117 to record water level fluctuations in an attempt to estimate the quantity of recharge. The water level fluctuations recorded to date are presented in Figure 15. Since the generated data comprises a very short period of time (approximately 2 months), it is not possible to draw any definite conclusion concerning recharge. However, the fluctu- ations do provide further evidence concerning the confined or unconfined nature of the overburden waters. Water levels in wells penetrating confined aquifers can.be expected to respond to changes in atmospheric pressure, while the water level in wells penetrating unconfined aquifers are generally insensitive to changes in atmospheric pressure. The water levels in wells 61 (coal ) and 117 (overburden) exhibit fluctuations typical of confined aquifers responding to changes in atmospheric pressure. Note that the fluctuations in these two wells correlate very nicely, indicating that the cause of the fluc- tuations are the same in both cases. In contrast, the water level in well 122 shows almost no fluctuation during the same time period. These observations strongly indicate that the overburden aquifer is confined in the vicinity of well 117 and unconfined in the vicinity of well 122. D. Water Quality - Samples for the determination of water quality were collected at ti two locations in the overburden (wells 117 and 172), two locations in 8,702 8G the coal (well 61 and 137) and three locations in Ennis Draw (wells 96. 30 — co — ^a a • ^ t0 • n —N n w cn C N p U a N C L •1 C J a Y O N c 4 p F Y A as 0 7 N N .C — ^ p y C1 Y — v 3 N N N O ^ aD 41 _ L ' •—• 7 O Q — m l_ a G 01 .t; ^ b P^O b ^ O O O 0 so C — O v p N CV N N N Pal - dal% 01 'oda4 psi 8 CJ� 31 97 and 122). The results of the analysis on the seven samples are shown in Table 3. The samples from Ennis Draw, on which the analysis were made , were collected after continuously bailing the wells. Those from the coal and overburden were collected from the pump discharge at the end of the pumping period during the aquifer tests. During the pumping period, the electrical conductivity, temperature, and pH were measured in the field at the time of sample collection. The samples collected were filtered through a 0.45 micron filter and one-half of the sample was acidified. The samples were then transported to the laboratory. The data in Table 3 show a striking difference between the waters in the coal and overburden. The water in the coal is of significantly better quality than that in the overburden, although in neither case can the water be regarded as acceptable for many uses. The large difference betwien the water quality in the coal and overburden aquifers is further evidence of little or no hydraulic communication between the coal and the overburden. Trace elements concentrations are generally low, the exception being iron in sample 117 and boron in sample 172. The observation that the trace elements in the overburden waters are significantly more concentrated than in the coal waters is probably partially explained by the fact that the overburden waters exhibit a lower pH than the coal waters. The sodium adsorption ratios (SAR) range from 10 to 18. These rather high SAR values, coupled with the high dissolved solid content, cause the waters to be . classified barely acceptable to unacceptable for irrigation, although this _ depends upon the type of soil and crop to which they would be applied. 870280 32 a 4 it • N- 0 0 0 0 0 0 0 0 Cn M OOM on F- E ^^OOo10 N.r-in,N. en O N o 0 0 ciao 0 0 O onto 0.- YN.-r- M.--• -O. 0 0 0 0 0 0 0 • N C3 M Or-NMcr 0 O^1 100 L N 0 C) 2 N. t0010C O N r- p 4-� t0 of CO A _ 3 MM10 M C71 O103 L l0 CT tO.N.- v .33 CM • G N�MOMNtp V v V ^ N Cl 13 L 13 to UO1010101010 77 OKSOOMOto V V -V V v y v v a • I- V r-• MIO.p0101001 CI N ^ r- V Ell OlOO� O .

In fact, the dissolved solid concentration of the overburden waters is greater than that of Ennis Draw by a factor of 6. In addition to determining the quality of ground waters in the leasehold, samples were collected from twenty-four additional wells in the general vicinity. The location and number of these wells are shown on the map in Appendix D. The temperature and electrical conductivity of the samples were measured. These data, together with other information supplied by the well owners, are presented in Table 4. It is difficult to draw any firm conclusions from the data on the wells in Table 4 because of insufficient knowledge of the depths, aquifers open to the well bore, and water levels. However, wells numbered W-1 , W-2, W-3, W-5, W-6; W-10 and W-24 which are all in the vicinity of the leasehold, are apparently completed in aquifers below the coal seam elevation. This is judged on the basis of the static water levels, length of pipe, and depth of hole. The total dissolved solids concen- tration (estimated from EC) is on the order of 750-1000 mg/1 in these wells. Information gathered from the city of Keensberg indicate that the dissolved solids concentration of the Foxhills waters is approximately 700 mg/1. This would strongly suggest that the above mentioned wells are completed in the Foxhills sandstone. Wells W-4, W-7, W-8, W-9, W-21 , W-22 and W-23 are relatively shallow wells located in Ennis Draw. Judging from their depths, static water levels and/or dissolved solids concentration, we firmly believe that these wells withdraw water from the streamsediments in the draw. However, it is possible that wells W-4 and W-9 are being affected by waters in the 870280 _ 34 Table 4. Well Inventory dindmill Owner Static Total Depth Length Temp Spec.Res.

E. Summary of Existing Situation Based on our analysis we have concluded that the overburden waters in the project site are unconfined except in the vicinity of well 117 where the overburden aquifer is locally confined. We are fairly confident that the coal seam is indeed a confined aquifer. The fact that the piezometric head in the: overburden is greater than in the coal suggest that there would be a tendency for water to move from the overburden into the coal if sufficient permeability existed. Evidence that such is not the case is provided by a comparison of the water quality in the two zones. The dissolved solids concentration in the overburden water is greater than in the coal waters by a factor of 2 or more. If there were significant hydraulic communication between the two aquifers the dissolved solids content of the two waters should not show such a dis- parity. Groundwater discharge through the coal seam was about 0.1 acre foot per year. This discharge is so small that it can be neglected for all practical purposes. ' Flow from the overburden to Ennis Draw was estimated at approximately 5.4 acre feet per year. It is not possible to calculate the actual flow from the south through Ennis Draw based upon data presently available to us. However, we do believe that the discharge through the draw from the south is significantly greater than the lateral inflow contributions from the over- burden in the study area. Evidence that such is the case is provided by - a comparison of the water• quality in the overburden and Ennis Draw. The fact that the overburden waters, with a dissolved solids concentration 7 of 7025 ppm, discharge into the draw suggests that the much lower dissolved 36 solids concentration observed in Ennis Draw must result from dilution with better quality water flowing from the south through the sand and stream deposits in the draw. Locally, water may be trapped in Ennis Draw. _ Although the water in the coil is of significantly better quality than that of the overburden, in neither case can the waters be regarded as acceptable for many uses. Anticipated changes in water quality as a result of mining are discussed in a subsequent section of this report. IV. Subsurface H drolon and Hater ualit During ltinina A. Pit Inflow Estimates Extraction of the coal seam by removing the overburden in strips and backfilling in the adjacent pit will completely disrupt the natural sequence of strata from the bottom of the coal seam to the surface. The existing strata will be replaced by a mixture of geologic materials in the form of rubble produced by the blasting and excavation of the over- burden and coal. The area to be mined is divided into three subareas, designated pits A, B, and C as shown in Figure 16. Except for a small area in the north- west corner of Pit A, the overburden will be removed by drag line, exposing the coal in a pit with the geometry of a trench 100 ft wide and 3000 ft long on the average. Operations will begin on the north boundary of Pit A and progress southward; the long axis of the pit being oriented in an approximate east-west direction. Mining will be confined to Pit A for the first year while a buried pipeline is removed from Pit B. After removal of the pipeline, the drag line will alternate between Pits A and B on each pass. Coal removal will occur in Pit B while the drag line is in Pit A and vice versa. 870280 37 • t • i, 3t, • \ ' \2aa '• a 3. ' \^ i9 i�r . V -\_,:15 kRT:..I - ` C..

Approximate extent of mining. 870 28 0 • 38 Using an average seam thickness of 5.86 ft, a trench width of 100 ft, a coal density of 80 lbs/ft3, and a mean production rate of 510,000 tons/yr, the rate at which the trench is extended is 50 ft/day, On the average, the maximum length of open trench •in Pit A will be 3000 ft, a length that will be achieved in some 60 days, assuming the average conditions presented above apply at the outset of mining. For the purposes of pit inflow estimates, it is further assumed that overburden removal in Pit B is initiated at the beginning of the second year and that the trench length is extended at the rate of 50 ft/day. Under these conditions, the maximum length of open trench at any time is 6000 ft. Inflow to the pit will occur from both sides and the ends. However, the area of aquifer exposed on the end of the trench is very small relative to the area exposed on the lateral surfaces of the pit, and inflow from the end of the trench was neglected, therefore. Depending upon the final . mining plan, there is one area in Pit A where the eastern extremity of the pit may intersect the old stream deposits in Ennis Draw_ Potential inflow for this case will be discussed subsequently. Regardless of whether the aquifers are confined or unconfined initially, the exposure of the aquifers in the pit will cause the aquifers to become unconfined in the vicinity of the pit. Therefore, the aquifers will respond according to a coefficient of storage (apparent specific • yield) characteristic of unconfined materials. Also, exposure of the aquifers in the pit causes the boundary condition on the outflow face of the aquifers to be that of atmospheric pressure. Because individual i aquifers in the overburden could not be identified, the interval extend- ing from the bottom of the coal seam to the existing piezometric surface • was regarded as the initial saturated thickness. The saturated thickness VV0280 39 varies from point-to-point, of course, but it was necessary to use a uniform average value in the computations. The use of a uniform initial saturated thickness does not severely limit the validity of the results , however. Inflow to the pit from all directions will occur when the trench is initiated, and the trench will be extended into overburden that has experienced some drainage, therefore. The difficulties of a rigorous mathematical treatment of this phenomena are considerable. An astimate of the maximum inflow that can be reasonably expected is made by assuming one-dimensional inflow through the lateral surfaces of the trench. During • the initial stages of overburden removal, the length of the trench will increase with time. This was handled by calculating the inflow to the trench in segments, taking into account that inflow into each segment begins at different times. Once the pit reaches maximum length, each new segment of the pit will be advanced into previously drained overburden, and it was assumed that no additional new inflow was induced. Therefore, inflow estimates after the trench has reached maximum length were made as if the position of the trench no longer changed with time. The cumulative volume of inflow from both sides of a trench segment of length L is estimated from Vi = 4L( 12 2 )-l/2 (t-t,)1/2 + q i(t t.) (1 ) 1 SyaTho where Vi = cumulative volume for segment i , (L3) - L = length of trench segment i, (L) Sya = apparent specific yield (dimensionless) , I = transmissivity (L2/T) , 870280 ho = initial saturated thickness (L) , 40 qo = natural flow in undisturbed aquifer per unit of trench length, (L3/LT) ti = time at which segment i came into existence (T). This equation was derived using a "succession of steady states" approach which accounts for the variable saturated thickness of the aquifer in the vicinity of the pit. The mean discharge (rate of inflow) over a time period is computed by dividing the volume that has accumulated over the period by the duration of the period. Inflow estimates were made by applying equation 1 to trench segments 500 ft in length. At a rate of advance equal to 50 ft/day, a new segment comes into existence every 10 days until a trench length of 3000 ft is obtained. After that time, no new segments are considered because the trench will be advancing into previously drained overburden as explained previously. The cumulative volume for the entire length of open trench • at any time is computed by adding the volumes contributed up to the time of interest by each segment. The estimated cumulative volume and rates of inflow are shown in Figure 17 for the first 460 days of operations. The following values were used for the parameters in equation 1 : T = 10 ft2/d (average deter- mined from aquifer tests), Sya = 0.05 (typical value for clay and shale materials), ho = 65 ft (average from Fig. 4) , qo = 0.08 ft2/d (from measured T and slope of piezometric surface) , and L = 500 ft. The first peak in discharge occurs at the time when the trench in Pit A reaches a length of 3000 ft. The subsequent decline of inflow rate represents the continued drainage to the 3000 ft trench under the influence of progres- sively smaller hydraulic gradients. The second peak occurs as the result of opening a new trench in Pit B during the first part of the second year 870280 41 Pal anno '3wnlon 3Ativinwn3 O p — ^ O O O O (� (� N o1 co r) P Kl N O • ) pN P 0 O P t n . ict 8 -0-.-. v t 0 _w In , • 0 N M O V co E N.

The rates and volumes of inflow shown in Figure 17 are probably the maximums that can be anticipated. As explained previously, the values of transmissivity obtained from the aquifer tests are believed to be greater than the actual values because they reflect the influence of well-bore storage not accounted for in the analysis procedure. Should the actual mean transmissivity be less than the value of 10 ft2/day used in the computations, inflow will be correspondingly less. It may also be that - the actual rate of extension of trench length will be less than the value of 50 ft/day used in the computations; if so, the inflow peaks will be less than presented herein. Finally, the computation procedure ignores that, during the period in which the length of open trench is increasing, new increments are being advanced into overburden that has been partially drained by previous segments. This also will cause the inflow to be less than estimated. It should be recognised that the inflow to the trench will be dis- tributed all along the trench in the form of seeps at various points on the high wall and emanating from beneath the spoil . The distributed nature of the inflow will tend to maximize evaporation and it is highly unlikely that inflow will become sufficiently concentrated in the trench to flow as a stream and require removal . It was mentioned previously that a portion of the area designated as Pit A in Figure 16 intersects the area, beneath which, stream deposits associated with the old Ennis Draw exist. Inflow to the east end of the trench could be substantial from these deposits should they be intersected, and it is recommended that special care be taken to prevent significant disturbance of the waters in Ennis Draw. The proposals, advanced by Coors , 670280 43 to: 1 ) construct a compacted shale cutoff trench on the east and south edges of the trench area that intercepts the old channel of Ennis Draw, or 2) restrict mining operations to those areas that will not substantially influence the subsurface water in the old channel of Ennis Draw will pro- vide adequate protection. B. Drawdown of Piezometric Surface Due to Pit Inflow The theory leading to Eq. 1 also provides a means for estimating the distance from the pit to points where the piezometric surface will remain essentially undisturbed. The equation is • L = STt )1/2 (2) ya • where L is the distance from the pit to the point where the drawdown of the piezometric surface is zero, and other symbols are as previously defined. Using T=10 ft2/d and Sya=0.05, Eq. 2 yields the values of L shown in Table 5. Examples of the predicted shape .of the piezometric surface in the vicinity of the trench are shown in Figure 18. Table 5. Distance From Pit to Line of Zero Drawdown in the The calculations shown in Table 5 Laramie Formation indicate that the disturbance of the L t ft years piezometric surface in the Laramie 230 0.25 330 0.50 caused by pit inflow will extend less 400 0.75 470 1.00 than 0.5 miles on either side of the 660 2 1050 5 pit. Therefore, at no time during mining . 1480 10 _ 2090 20 should the piezometric surface in the — Laramie be disturbed beyond about 0.5 miles from the pit location. This relatively small extent of the influence of the pit is due mainly to the very small hydraulic conductivity of the Laramie overburden, causing the drawdown profile to be very steep in the vicinity of the pit. 870230 44 • • • • • • a CU 4-, w• O N • _O V A • • 0 0 e _8 v N C a N .- T- A • -$ W N r0 G 1-- 14 L d N CD p O r -0 Ct w • t' L t„, a a ill z u .. fa p ~ .4-- • -8 a s W O N • 0 t_v 4• a — • cij-8 E o n T • .• TR N O o V r N 0 Cl.r - 0 - , N a 5.- z 0 L 8 oa U3Q O OO - • laai ' a0014 lid 3A08v 33vd8l1S 312i13WOZ31d JO 1H9131-1 - • -O. • • • 870280 45 The distance to which drawdown of water levels would occur in the stream deposits in Ennis Draw, should they be intersected by the pit, can- not be estimated quantitatively, The drawdown due to pit inflow could extend over a very large area depending upon the transmissivity of inter- sected deposits. Again, it is recommended that special care be taken to protect the waters in. Ennis Draw from significant disturbance by either of the methods described previously. C. Quality of Mine Inflow The quality of waters presently existing in the overburden and coal ti aquifers is shown in Table 3. Water seeping into the pit fran the high- wall side will be a mixture of water from the coal seam and from the . overburden. Because the contribution from the coal seam will be quite small relative to that from the overburden, the quality of the seepage into the pit from the highwall will be essentially that of the existing overburden waters. Seepage from the side of the pit opposite the highwall must pass • { through the spoils before entering the pit. Experience with the quality of waters passing through spoil banks formed from the Williams Fork form- ation in western Colorado suggests that the effluent water will contain dissolved solids at a concentration about equal to that in water equil- ibrated with and saturating representative samples of the overburden. Similar experience in the Fort Union formation suggests that water saturating spoils will exhibit dissolved solids concentrations exceeding that in saturation extracts by a factor of about 2. Table 6 shows the pH and electrical conductivity (EC) of saturated extracts prepared from composite grab samples taken from 3 cores in the Laramie formation. ) e7 280 46 • Comparison of the EC values in Table 6. EC and pH of Saturated Extracts (Composite samples Table 6 with those for the overburden from Cores) water samples in Table 3 shows that Core No. pH EC @ 25°C mrnhos/cm the :existing dissolved solids concen- 83 7.8 4.3 65 73 6.9 tration is greater than that in the 101 7.6 6.7 saturated extracts, Based on the previous experience which suggests that spoil water will contain dissolved solids concentrations between 1 and 2 times that in saturated extracts and that the existing waters are already in this range, no appreciable further degradation of water quality is anticipated as the ground water passes through the spoils. Therefore, the quality of pit inflow should be nearly that shown in Table 3 for overburden waters. As previously noted, the water quality is such that the usefulness is probably limited to dust control or other non-agricul- turaror domestic use. Furthermore, the quantity of inflow is likely to be too small to be effectively concentrated and used. V.. Post-Mining Hydrology and Water Quality A. Post-Mining Flow Patterns and Hydrology Foliating the termination of mining, there will exist a period during which the spoils will tend to resaturate and water levels rise toward the premining values. We have no viable computation procedure for estimating the recovery time. Experience suggests that water levels will probably recover substantially within about 3 years following the termination of mining. In any case, recovery time is of little importance since no use of overburden waters presently exists. Recovery of water levels in the stream deposits in Ennis Draw is a more important consideration since there exist wells completed in these deposits in the vicinity of the proposed mine. Again, it is not possible 070280 47 to estimate the recovery time quantitatively. However, it is reasonably certain that no permanent reduction of water levels in the stream deposits will result from mining. The apparently substantial flow from the south will tend to replenish any materials dewatered as a result of the mining pit incising the'deposits. Should either of the previously described methods for protecting these waters during mining be adopted, there should be no substantial disturbance of the water levels in Ennis Draw. There is no way by which the hydraulic conductivity of the spoils can be estimated quantitatively. The large clay content in the Laramie • formation suggests that the hydraulic conductivity will be small , probably on the same order as that of the pre-mining overburden. In this case, the flow pattern through the aquifer will eventually return to essentially the existing pattern. If the hydraulic conductivity of the spoils is less-than that of the surrounding aquifer, there will be a partial diver- sion of water around the mined area: on the other hand, there will tend to be a concentration of flow through the spoils if their hydraulic con- ductivity is greater than that of the surrounding aquifer. Again, the post-mining'flow pattern in the Laramie is of little practical concern since no use of this water is made in the vicinity of the project. Consideration has been given to pushing much of the blow sand mantling the Laramie into the pit before backfilling with spoil. If this is in fact accomplished, it is likely that the resulting layer of sand beneath the spoils will become the major avenue for flow in the mined area. We - see no problem with this plan except in the area where the pit has cut through the stream deposits in Ennis Draw. Contact of the sand layer CA,I underlying the spoils with the stream deposits would form a hydraulic con- nection between the waters in the stream deposits and in the mined area 87028,6 that is much better than existed prior to mining. The_cnncpmipnrpc of 48 the improved hydraulic connection are not clear. Constructing a compacted shale trench to prevent communication between pit backfill and the deposits in Ennis Draw or restricting mining so that the deposits are not inter- sected is recommended. B. Post-Mining Water Quantity and Quality We believe that the sources of existing ground waters on the lease- hold are located exterior to the site and will not be affected by the mining operations. Further, the disturbance of the overburden should not change the quantity of vertical recharge which is probably negligibly small. Thus, the mining operations should not significantly alter the existing quantities of water passing through the leasehold, once the water levels have recovered. This statement is based upon the assumption that a permanently improved hydraulic connection between waters in Ennis Draw and the leasehold is avoided. Based on a comparison of the EC of saturation extracts prepared from composite samples of the overburden with that for existing overburden waters, no further degradation of water quality is anticipated as ground water passes through the spoils. Protection of water quality in the stream deposits in Ennis Draw can be provided by a compacted shale trench in areas where the pit cuts into these deposits, or by not permitting the mining operations to intersect the deposits. 1 870280 ' . 49 VI.

Trousil Coors Energy Company P.O. Box 359 Keenesburg, Colorado 80643 Re: HRI Project 005-806 Analysis of Fly Ash from Boiler #4 Dear Mr. Trousil: As a part of your effort to obtain permission to dispose of fly ash from the brewery power plant at the Keenesburg mine, you asked Hazen to analyze a sample of fly ash from Boiler #4. Since it was not known what analyses would be required for in-pit disposal at Keenesburg, I contacted Dennis Hotovek at the Colorado Department of Health and West Potter with the Weld County Health Protection Services. There appear to be no hard and fast requirements regarding specific analyses but, according to these individuals, two types of analyses should be sufficient: the EPA EP Toxicity Test, and a trace metals analysis. In addition, Mr. Potter indicated that he would like to.have a one-pound sample for their own analysis. The EP Toxicity Test results are shown in Table 1. Analyses of the extract for eight toxic metals fall well within the limits set by the EPA for hazardous waste. EPA guidelines for defining a hazardous waste are contained in 40 CFR Part 261 published by the Bureau of National Affairs. A copy of this regulation is attached for reference. The definitions of a hazardous waste and test procedures used by Hazen for determining toxicity are contained in the regulation. It should be noted that fly ash and bottom ash are specifically cited in the regulation as not being hazardous wastes (Part 261.4(b) Exclusions). Trace metals analyses are listed in Table 2. The technique used for the analysis was spark source mass spectroscopy, and the work was completed by WAL, Inc. in Golden, Colorado. Elements listed as major components in the fly ash were detected in concentrations exceeding 1000 ppm (1% by weight), and include the following: C70280 0280 Mr. Robert E. Trousil November 11, 1986 Page 2 Calcium Potassium Aluminum Iron Silicon Barium Titanium Phosphorus Magnesium Strontium Sodium Although many of the elements listed in the analysis would be hazardous if present in larger quantities and in pure form, the compounds present in the fly ash are not hazardous because they are not leachable under naturally occurring circumstances. This is evidenced by the examples of barium, chromium, lead, selenium, and arsenic, which are listed in the trace element analysis, but were not leached in the toxicity test. If you have questions on the analysis, please contact me. Very truly yours, HAZEN RESEARCH, INC. C. W.
