BUFFALO RIDGE ENERGY SERVICES FACILITY WELD COUNTY, COLORADO Figure Well Location Map Enclosure D FINDINGS OF THE STATE ENGINEER IN THE MATTER OF AN APPLICATION FOR A PERMIT TO CONSTRUCT A WELL IN WATER DIVISION NO. 1, WELD COUNTY, COLORADO APPLICANT : WASTE SERVICES COMPANY AQUIFER: LARAM1E-FOX HILLS PERMIT NO.: 1H6_"" F In compliance with C.R.S. 37-90-137(1) and the Statewide Nontributary Ground Water Rules, Waste Services Company, P.O. Box 3.5.9, Keenesburg, CO 80643, (hereinafter "applicant") submitted an application for a permit to construct a well. Based on information provided by the applicant and records of the Division of Water Resources, the State Engineer finds as follows: 1. The application was received complete by the State Engineer on March 7, 1996. 2. The applicant proposes to construct the well in the SEA of the SW1 of Section 35, Township 3 North, Range 64 West, 6th Principal Meridian. 3. The proposed well is located outside the boundaries of a designated ground water basin. 4. The applicant proposes to apply the water withdrawn from the well to the following beneficial uses: industrial (including dust control, construction, revegetation, miscellaneous facilities, and stock watering) 5. The proposed maximum pumping rate of the well is 160 gallons per minute, and the requested average annual amount of ground water to be withdrawn is 50 acre-feet. 6. The applicant is the owner of the land on which the well will be constructed. 7. The proposed well would withdraw ground water from the Laramie -Fox Hills Aquifer (hereinafter "aquifer"), which, according to the Denver Basin Rules, is located at a depth of approximately 450 feet below land surface and extends to a depth of approximately 790 feet below land surface at the location of the proposed well. B. The location of the proposed well is more than 600 feet from any existing well completed in the aquifer. 9. According to a sworn statement, the applicant owns, or has consent to withdraw ground water underlying 4,640 acres of land as further described in said statement, which is attached hereto as Exhibit A. 10:" Withdrawal of ground water from the aquifer underlying the land claimed by the applicant will not, within one hundred years, deplete the flow of a natural stream at an annual rate greater than one -tenth of one percent of the annual rate of withdrawal and therefore the ground water is nontributary ground water as defined in C.R.S. 37-90-103(10.5). Applicant: Waste Services Company Aquifer: Laramie -Fox Hills Permit No.: - -1 Page 2 11. In considering whether the requested permit shall be approved the provisions of C.R.S. 37-90-137(4) and the Denver Basin Rules shall apply. Withdrawals shall be allowed on the basis of an aquifer's life of 100 years, C.R.S. 37-90-137(4)(b)(l). 12. The quantity of water in the aquifer, exclusive of artificial recharge, underlying the 4,640 acres of land described In Exhibit A is 115,536 acre-feet. This determination was based on the following as specified in the Denver Basin Rules: a. The average specific yield of the. saturated aquifer materials underlying the land under consideration is 15 percent. b. The average thickness of the saturated aquifer materials underlying the land under consideration is 166 feet. 13. A review of the records in the State Engineer's office has disclosed that there is an existing well withdrawing ground water from the aquifer underlying the land claimed by the applicant. Well Permit Number 161814-A was issued to Gutterson and Company for a well in the SW1/a of the NE1/4 of Section 10, Township 2 Nprth, Range 64 West, 6th P.M., to withdraw ground water from the aquifer at a rate of 1.0 acre-feet annually for livestock watering. To prevent material injury to such vested water rights, the quantity of water underlying the land claimed by the applicant which is considered available for withdrawal has been reduced from 115,536 acre-feet (from paragraph 12, above) to 115,436 acre-feet. This reduction was based on a calculation of the ground water necessary to provide a quantity of water underlying such lands as would be sufficient for the persons entitled to withdraw water under the existing permit to withdraw the average annual amount of water from the aquifer for the minimum useful life of the aquifer (100 years). 14, No application for nontributary underground water rights for the proposed well is pending in the Division 1 Water Court. Based on the above, the State Engineer finds that there is water available for withdrawal by the proposed well and no material injury to vested water rights would result from the issuance of the requested permit subject to the following conditions: a. The allowed average annual amount of water to be withdrawn from the aquifer by the well shall not exceed 50 acre-feet (the quantity of water which has been requested by the applicant). b. The well shall be constructed no more than 200 feet from the location specified on the permit application. c. The applicant shall submit geophysical and lithologic logs after the construction of the well. The geophysical logs shall be obtained from the hole before the casings are installed. d. The maximum pumping rate of the well shall not exceed 160 gallons per minute. Applicant: Waste Services Company Aquifer: Laramie -Fox Hills Permit No.: 1-(C3S6V Page 3 e. A totalizing flow meter must be installed on the well and maintained in good working order. Permanent records of all diversions must be maintained by the well owner (recorded at least annually) and submitted to the Division Engineer upon request. f. Production is limited to the Laramie -Fox Hills Aquifer. The well must be constructed with plain, non -perforated casing properly grouted so as to prevent Intermingling of water between aquifers. g. Pursuant to C.R.S. 37-90-137(9)(b) and the Denver Basin Rules, no more than 98% of the nontributary ground water withdrawn annually shall be consumed and the applicant shall demonstrate to the reasonable satisfaction of the State Engineer that no more than 93 of the water withdrawn will be consumed. h. The owner shall mark the well in a conspicuous place with appropriate well permit numbers, name of the aquifer, and court case numbers. He shall take necessary means and precautions to preserve these markings. Dated this c24 day of Prepared by: DAM 397424A,FD4/Fbrm #0546(o) By: ,19 ?cc' . Ha D.

Adjacent to the proposed site, the Buffalo Ridge landfill is located approximately 1 mile northwest. Details of the proposed site are shown on the attached Site Plan (Figure 2) and the site evaluation is discussed below. The proposed Buffalo Ridge Energy Services Facility consists of various waste processing facilities, a class 2 deep injection well, an office/maintenance building, and a scale house. The proposed class 2 deep injection well will be approximately 400 feet northwest of the proposed OWTS location. There are no existing structures within approximately 500 feet of the proposed OWTS location. Currently, the site is sparsely vegetated and generally slopes to the northeast at an approximate 3% slope. Approximately 500 feet northwest of the proposed OWTS location, an existing oil and gas well (Waste Management D #35-15) is located. A scale house, small pond, and maintenance building have been constructed for the Buffalo Ridge landfill operation approximately 1,700 feet west of the proposed OWTS location. Based on our observations, the project site was previously used for cattle grazing. Please find enclosed percolation test and engineered design for a proposed On -site Wastewater Treatment System (OWTS) for the above referenced site depicted on Figure 2. A representative of RMG - Rocky Mountain. Group performed a soil percolation test on September 12, 2014. The percolation test with 4 percolation holes was performed in accordance with Weld County Department of Health and Environment On -site Wastewater Treatment System Regulations. RMG investigated the site on September 11, 2014 using a CME-45 truck mounted drilling rig advancing 4 -inch outside diameter continuous flight augers for the profile bore and 8 -inch outside diameter continuous flight augers for the percolation bores. Silty sand soils were encountered in the profile soil boring attached, Test Boring Log, Figure 4. Attached are the Southern Office: Colorado Springs, CO 80918 719.548.0600 Central Office: Englewood, CO 80112 303.688.9475 Northern Office: Evans, CO 80620 970.330.1071 Monument: 719.488.2145 Woodland Park: 719.687.6077 Erbil/Kurdistan Iraq: 0750 192 99 44 Ulaanbaatar, Mongolia: 976 99106671 www.rmgengineers.com Weld County, Colorado Explanation of Test Boring Logs on Figure 5 and Soil Classification Date on Figure 6. No groundwater or limiting zones were encountered to a depth of eight feet (8'-0") below existing grade. The average percolation rate at the site was found to be 4.7 minutes per inch at a depth of 36 - inches below existing grade, as shown on Table No. 1, Percolation Data Summary. When correlated the percolation rate and site soil data indicate soil type 1 found on Table 30-10-1 of the On -Site Wastewater Treatment System Regulations. Based on Table 30-10-1, the OWTS should be designed using a Long Term Acceptance Rate (LTAR) of 0.80 gallons per day per square foot. An engineer designed septic system is required since the system will serve a commercial endeavor. The owner will have to meet the required distance criteria as shown in Table 30-7-1 of the Weld County Department of Health and Environment On -Site Wastewater Treatment System Regulations, enclosed. The location of the percolation tests and proposed Soil Treatment Area (STA) will be greater than all horizontal and vertical separation distances as shown in Table 30-7-2. No other objects requiring setbacks from the proposed OWTS as indicated on Table 30-7-1 and 30-7-2 of Chapter 30 of the Weld County Code, have been located or observed during our preliminary investigation, reconnaissance or detailed soil investigation. It is our understanding the proposed facility will have 45 full time workers per day. The facility will work three 8 hour shifts. Two people per shift will be in the scale house and the remaining employees will use the maintenance shop facilities. We use a flow rate of 15 gallons per day per employee in the scale house and 20 gallons per day per employee for the shop in accordance with Table 30-6-2. Both locations will share one Soil Treatment Area (STA) but were designed with their own septic tank. The system was designed with a total design flow of 890 gallons/day; 90 gallons/day from the scale house and 800 gallons/day from the shop. The scale house and shop will be served with a minimum 400 gallon and minimum 1750 gallon two compartment tank meeting the regulations outlined in Section 30-9-20. An adjusted required soil treatment area of 778.8 square feet using trenches with chambers was used to identify the need for a minimum of 65 Quick Four Infiltrator units. See enclosed calculations. We anticipate an approximate cover of 6" to 12" cover over the septic tank and a 12" to 18" cover over the distribution box. Both the septic tank and distribution box must have access from the surface. The bottom of the chambers should be placed approximately 24" to 30" below existing grade and will require observation ports on each row of chambers. We are not aware of any previous septic reports on this lot or neighboring properties that may affect the placement of the proposed OWTS. Furthermore, we are not aware of any existing easements or right-of-ways that may conflict with the proposed OWTS. We found no location of any visible or known unsuitable, disturbed, or compacted soils. We do not anticipate difficulties with the construction of this system on this site. We anticipate this area to remain industrial use for the foreseeable future. There were no difficulties encountered during the site evaluation. During septic system installation the subsurface conditions encountered in the absorption field excavation may vary from those we encountered in the profile boring and percolation holes of the percolation test. Percolation rates, relative bedrock depths and groundwater levels may be different from those discussed in this report. If subsurface conditions encountered in the septic Rocky Mountain Group - RMG 2 Job No. 144620 Weld County, Colorado field differ from those reported for this percolation test, RMG should be retained to review the subsurface conditions. The percolation test was conducted at the request of KBN Engineers in a location determined by KBN Engineers. I hope this provides the information required for the proposed OWTS. Should you have questions, please feel free to contact our office. Cordially, Reviewed by: Ryan Laird, P.E. Thomas M.

Box 3.5.9, Keenesburg, CO 80643, (hereinafter "applicant") submitted an application for a permit to construct a well. Based on information provided by the applicant and records of the Division of Water Resources, the State Engineer finds as follows: 1. The application was received complete by the State Engineer on March 7, 1996. 2. The applicant proposes to construct the well in the SEA of the SW1 of Section 35, Township 3 North, Range 64 West, 6th Principal Meridian. 3. The proposed well is located outside the boundaries of a designated ground water basin. 4. The applicant proposes to apply the water withdrawn from the well to the following beneficial uses: industrial (including dust control, construction, revegetation, miscellaneous facilities, and stock watering) 5. The proposed maximum pumping rate of the well is 160 gallons per minute, and the requested average annual amount of ground water to be withdrawn is 50 acre-feet. 6. The applicant is the owner of the land on which the well will be constructed. 7. The proposed well would withdraw ground water from the Laramie -Fox Hills Aquifer (hereinafter "aquifer"), which, according to the Denver Basin Rules, is located at a depth of approximately 450 feet below land surface and extends to a depth of approximately 790 feet below land surface at the location of the proposed well. B. The location of the proposed well is more than 600 feet from any existing well completed in the aquifer. 9. According to a sworn statement, the applicant owns, or has consent to withdraw ground water underlying 4,640 acres of land as further described in said statement, which is attached hereto as Exhibit A. 10:" Withdrawal of ground water from the aquifer underlying the land claimed by the applicant will not, within one hundred years, deplete the flow of a natural stream at an annual rate greater than one -tenth of one percent of the annual rate of withdrawal and therefore the ground water is nontributary ground water as defined in C.R.S. 37-90-103(10.5). Applicant: Waste Services Company Aquifer: Laramie -Fox Hills Permit No.: - -1 Page 2 11. In considering whether the requested permit shall be approved the provisions of C.R.S. 37-90-137(4) and the Denver Basin Rules shall apply. Withdrawals shall be allowed on the basis of an aquifer's life of 100 years, C.R.S. 37-90-137(4)(b)(l). 12. The quantity of water in the aquifer, exclusive of artificial recharge, underlying the 4,640 acres of land described In Exhibit A is 115,536 acre-feet. This determination was based on the following as specified in the Denver Basin Rules: a. The average specific yield of the. saturated aquifer materials underlying the land under consideration is 15 percent. b. The average thickness of the saturated aquifer materials underlying the land under consideration is 166 feet. 13. A review of the records in the State Engineer's office has disclosed that there is an existing well withdrawing ground water from the aquifer underlying the land claimed by the applicant. Well Permit Number 161814-A was issued to Gutterson and Company for a well in the SW1/a of the NE1/4 of Section 10, Township 2 Nprth, Range 64 West, 6th P.M., to withdraw ground water from the aquifer at a rate of 1.0 acre-feet annually for livestock watering. To prevent material injury to such vested water rights, the quantity of water underlying the land claimed by the applicant which is considered available for withdrawal has been reduced from 115,536 acre-feet (from paragraph 12, above) to 115,436 acre-feet. This reduction was based on a calculation of the ground water necessary to provide a quantity of water underlying such lands as would be sufficient for the persons entitled to withdraw water under the existing permit to withdraw the average annual amount of water from the aquifer for the minimum useful life of the aquifer (100 years). 14, No application for nontributary underground water rights for the proposed well is pending in the Division 1 Water Court. Based on the above, the State Engineer finds that there is water available for withdrawal by the proposed well and no material injury to vested water rights would result from the issuance of the requested permit subject to the following conditions: a. The allowed average annual amount of water to be withdrawn from the aquifer by the well shall not exceed 50 acre-feet (the quantity of water which has been requested by the applicant). b. The well shall be constructed no more than 200 feet from the location specified on the permit application. c. The applicant shall submit geophysical and lithologic logs after the construction of the well. The geophysical logs shall be obtained from the hole before the casings are installed. d. The maximum pumping rate of the well shall not exceed 160 gallons per minute. Applicant: Waste Services Company Aquifer: Laramie -Fox Hills Permit No.: 1-(C3S6V Page 3 e. A totalizing flow meter must be installed on the well and maintained in good working order. Permanent records of all diversions must be maintained by the well owner (recorded at least annually) and submitted to the Division Engineer upon request. f. Production is limited to the Laramie -Fox Hills Aquifer. The well must be constructed with plain, non -perforated casing properly grouted so as to prevent Intermingling of water between aquifers. g. Pursuant to C.R.S. 37-90-137(9)(b) and the Denver Basin Rules, no more than 98% of the nontributary ground water withdrawn annually shall be consumed and the applicant shall demonstrate to the reasonable satisfaction of the State Engineer that no more than 93 of the water withdrawn will be consumed. h. The owner shall mark the well in a conspicuous place with appropriate well permit numbers, name of the aquifer, and court case numbers. He shall take necessary means and precautions to preserve these markings. Dated this c24 day of Prepared by: DAM 397424A,FD4/Fbrm #0546(o) By: ,19 ?cc' . Ha D.
