Enclosed for your consideration are the following: • • • • • • • • WYPDES Permit Application for CBNG Water Discharge Table 1: Outfall Information Table 2: Well Information Table 3: Reservoir Information Table 4: Bonding Information Table 5b: Water Budget Calculations and Explanation Representative Water Quality Permit Application Map Under this WYPDES permit application, Yates requests to discharge produced CBNG water from up to 137 wells to be completed within the Big George and Wyodak coal seams, into 23 on-channel reservoirs through 23 outfalls. These reservoirs have been sited in coordination with the respective landowners. Please note that the water from the associated wells may be piped to an additional network of outfalls covered under the WY0047741 Marker/Benchmark CS State – Nut Creek Drainage, WY0047775 Marker/Benchmark CS State – Nut Creek Drainage, WY0038784 Bucko CS State, WY0051438 Bucko POD, and Gauge POD – Beaver Creek permits. As supported by the attached water budget, Yates will contain all CBNG effluent within associated reservoirs under dry operating conditions. However, the reservoirs may overtop naturally if and when triggered by a storm event. Yates requests for a permitted flow limit of 2.95 MGD, which is based upon available reservoir capacity. Yates understands that Mr. John Iberlin of Iberlin Ranch LP submitted a statement of beneficial use to the Wyoming Department of Environmental Quality – Water Quality Division (WDEQ – WQD) in support of the Citation Oil & Gas Corporation WY0049204 renewal application. From this letter, Yates understands that Mr. Iberlin does not wish to seek protection for the irrigation use associated with spreader dikes on his property, specifically in Section 7, Township 46 North, Range 75 West, as the CBNG produced water has benefited his ranching operations. Therefore, Yates requests that WDEQ – WQD not include irrigation limits and monitoring requirements within its Gauge POD – Pumpkin Creek WYPDES permit. CBM ASSOCIATES, INC.

The discharge rate of 3.7 MGD has been calculated based on the flow from 113 new wells producing @ 22 gpm/well and 24 existing wells producing @ 3.46 gpm/well. 2 Freeboard Capacity is calculated using a CBMA developed water management tool which utilizes well completions schedules, water production decline rates, reservoir infiltration decline rates, and monthly evaporation rates. This value reflects the day where the water level in the reservoirs is projected to be at its highest given the projected production rates which are generally less than the permitted flow rate. 3 Daily CBM discharge equals (total wells) * (discharge rate per well) * (60 minutes/hr) * (24 hrs/day) / (325851.43 gallons/acre-ft) *79.8%. The remaining discharge (20.2%) goes to Gauge POD Beaver Creek. The daily CBM discharge has been divided based on the available reservoir capacites of Gauge POD - Pumpkin Creek and Gauge POD - Beaver Creek, respectively. The requested flow rate for Gauge POD - Pumpkin Creek is 2.95 MGD. 4 See attached explanation document for source and formula/rationale for total daily evaporation (all evaporation rates are based upon the surface area of the stored volume of CBNG water rather than the entire surface area). 5 See attached explanation document for source and formula/rationale for total daily infiltration (all infiltration rates are based upon the stored volume of CBNG water rather than the entire capacity). ADDITIONAL COMMENTS Some evaporation rates may equal zero because the most conservative day of the year falls in the winter where evaporation is negligible. Wells permitted to Gauge POD - Pumpkin Creek are also permitted to WY0038784, WY0047741, WY0047775, WY0051438, and Gauge POD - Beaver Creek. This calculation shows that in a worst case scenario discharge from associated producing wells can be stored in the Gauge POD - Pumpkin Creek and Gauge POD - Beaver Creek reservoirs.

Pertinent findings of available literature for this region of Wyoming are as follows. USGS Water Supply Paper 1531. Hydrology of the Upper Cheyenne River Basin: Part A. Hydrology of Stock-Water Reservoirs in Upper Cheyenne River Basin, by R.C. Culler, 1961. Fifty-four reservoirs with an average surface area of 2.12 acres were monitored for four years, 1951 - 1954. Reported evaporation and seepage loss rates are shown in Table 1. Table 1: Evaporation and seepage losses from 1951 – 1954 in the Cheyenne River Basin Year Evaporation (feet/month) Seepage (feet/month) 1951 1952 1953 1954 0.41 0.38 0.44 0.41 1.28 0.80 0.76 0.82 The stock-water reservoirs in the Culler study were typically much older bodies of water than CBM-related reservoirs. A newly constructed CBM-related reservoir should have a much higher seepage rate than the seepage rates of reservoirs addressed in the Culler study, especially if the reservoir bottom was excavated relatively deeply according to standard practice. The following references provide additional guidance: USGS Water Resources Series No. 47, Characteristics of Wyoming Stock-Water Ponds and Dike Spreader Systems, by Verne E. Smith, July 1974. The authors discuss the hydrology of stockwater ponds, evapotranspiration, and seepage. While this study was conducted for stock ponds, the governing concepts are pertinent to CBM water management requirements in small reservoirs. USGS Water Resources Investigations 82_4105, Evapotranspiration Rates at Selected Sites in the Powder River Basin, Wyoming and Montana, by L.W. Lenfest, 1987. This report provides the results of studies at twelve sites where the authors evaluated the effects of alluvial valley width on measured evapotranspiration. Overall, the above references combined with recent field observations conducted by Hugh Lowham (USGS-retired) provide a reasonably consistent estimate of combined evaporation and seepage losses in newly constructed small reservoirs. Hugh Lowham, P.E., has summarized available data and field observations to yield the following estimates for total loss rates of newly constructed small reservoirs in the Powder River area: Very small reservoir (2 acre-feet storage volume): 40 gpm Small reservoir (10 acre-feet storage volume): 80 gpm Medium, reservoir (20 acre-feet storage volume): 200 gpm Large Reservoir (200 acre-feet storage volume): 400 gpm CBM ASSOCIATES, INC.

Generally, initial infiltration rates decrease with time as a result of: 1) Gradual deterioration of the soil structure. 2) Partial sealing of the wetted soil profile by the formation of surface crust. 3) Detachment and migration of pore-blocking particles. 4) And swelling of clay particles (Hillel, 2004). Steady-state infiltration rates (Is) can be estimated by dividing initial loss rate estimates, as shown above, by a factor of 3. Potential evapotranspiration rates for the Powder River Basin have been estimated from evaporation pan studies. Data for evaporation rates in Wyoming are available online from the Western Regional Climate Center (http://www.wrcc.dri.edu/htmlfiles/westevap.final.html#WYOMING). Mean evaporation rates were obtained from studies conducted during an 81-year period (1925-2005) of four-foot Class A evaporation pans at the Gillette 9 ESE Station. Actual lake evaporation rates can be calculated by multiplying observed pan loss rates by a pan coefficient factor of 0.70 (Viessman and Lewis, 2003). Mean and adjusted evaporation values are shown in the Table 2: Table 2: Powder River Basin Evaporation Rates Month January February March April May June July August September October November December Average Average/year Evaporation Mean (inches) 0 0 0 4.52 6.4 7.5 9.88 9.44 6.18 4.36 2.39 0 4.24 50.67 Adjusted Evaporation Mean (inches) 0 0 0 3.16 4.48 5.25 6.92 6.61 4.33 3.05 1.67 0 2.97 35.47 Subtracting average evaporation rates from the Lowham initial total loss rates and dividing by the steady state factor of 3 gives the resulting steady-state infiltration rates, shown below. Very small reservoir (2 acre-feet storage volume, 0.67 acres of surface area): Small reservoir (10 acre-feet storage volume, 1.36 acres of surface area): Medium, reservoir (20 acre-feet storage volume, 2.49 acres of surface area): Large Reservoir (200 acre-feet storage volume, 20.45 acres of surface area): 12.92 gpm 25.84 gpm 65.15 gpm 120.84 gpm Curve fitting these data points on a graph yields the following power equation (see graph): y = 14.74x0.40 Where y is the steady-state infiltration rate in gallons per minute, and x is the reservoir capacity in acre-ft.

Although this variability may not be fully predictable, the inclusion of additional site-specific data should better constrain actual seepage and evapotranspiration losses at a particular location once a new reservoir is constructed and operated.
