Describe the control measures that will be implemented to prevent significant damage to or erosion of the receiving water channel at the point of discharge. The effluent water will be piped from Rock Well’s production field east to the proposed outfall at the Bighorn River (Map 1). The town of Greybull has given permission to Rock Well to tie their discharge pipeline into the town’s storm sewer line. The effluent will flow to the river under low-flow gravity drainage only (no pumps). This storm sewer is piped and discharges to the west side of the Bighorn River; the last ~40 feet above the river outfall is a rock-lined open channel that reduces discharge flow velocity and erosive energy. _____________________________________________________________________________________________ 13. Describe the control measures that will be implemented to achieve water quality standards and effluent limits. If proposing to utilize a treatment process, provide a description of the treatment process. Oilfield produced water will be treated at the production field prior to discharge by passing it through typical oil skim tanks or pits to which Champion “Cleartron ZB-216” de-emulsifier has been added to reduce oil and grease concentrations to the 10 mg/L limit. After the skim tank treatment, water will be stored in a 10,000-barrel storage tank and aeration/evaporation pond (Map 1) and to further reduce volatile organic compound concentrations prior to discharge. _______________________________________________________________________________________ 14. Outfall locations must be established as part of a preliminary field reconnaissance survey using GPS or conventional survey equipment and documented in Table 1. Please document the type of equipment used, the expected accuracy of your measurements, and a brief rationale for locating the outfalls at the requested sites below. The outfall listed on Table 1 and shown on Map 1 was located in the field using a Trimble brand Geo XH model GPS unit using a wide-angle augmentation system with an approximate accuracy of 50 feet. The Town of Greybull has given permission to Rock Well to tie their pipeline into this storm sewer, installed by the Town, to convey their discharge water the remaining distance to the river. This will make use of an already existing pipeline, saving the disturbance, time, and expense of installing a new WYPDES Application for Permit to Discharge Produced Water: Application for Coal Bed Methane New Discharges, Renewals, or Major Modifications, revised 04-25-07 ROCK WELL PETROLEUM, INC: 2007-12-27 / 10080010 / NEW NON-CBM: GREYBULL OIL FIELD Page 3 of 8 (06-554.DOC) pipeline the entire distance to the river. Engineering estimates indicate that this 18” – 30” diameter pipeline has sufficient capacity to convey both Rock Well’s effluent plus storm water. ______________________________________________________________________________________________ 15.

For new facilities, provide the expected (estimated) flow volume from each well in gallons per day, and provide the rationale behind the flow volume estimate. For existing facilities, provide actual flow data from all wells within the last six months. Based on Rock Well’s site water production measurements, total (all wells) maximum daily flow is estimated at 3500 barrels per day (= 102 gpm) produced water + 7 gpm tunnel water = 109 gpm total effluent = 157,080 gallons per day = 0.157 MGD = 0.243 cubic feet per second. ___________________________________________________________________________________________ 21. For applications for new facilities, are any of the required chemical constituents in the laboratory analysis present in concentrations above Wyoming Water Quality Standards? YES NO If the answer to question # 21 is yes, answer 21.a. – 21.b below. If no, proceed to question 23. a. Which constituents? Oil & grease b. Has this constituent been addressed in the response to question 13? Yes Excepting oil & grease, several produced and tunnel water quality samples collected from the Greybull Field (Table 3) indicate that the proposed discharge water quality can be expected to meet typical permitted effluent water quality limits without treatment prior to discharge. Rock Well has conducted Whole Effluent Toxicity (WET) tests, both acute and chronic on Ceriodaphnia and fathead minnow, using Greybull Field effluent (produced + tunnel water) in Bighorn River water. Results are available upon request. 22. For applications for existing facilities, has the facility ever exceeded permit limits or water quality standards? n/a YES NO If the answer to question 22 is yes, answer 22.a. – 22.c. If no, proceed to question 23. a. Which constituents? b. Has the exceedance been addressed? c. Describe how the exceedance was addressed. 23. Is there active irrigation in the drainage downstream of the discharge? (Please note that this response includes both artificially and naturally irrigated bottomlands as defined in the Draft Agricultural Use Protection Policy for the interpretation and implementation of Chapter 1, Section 20 of the Wyoming Water Quality Rules and Regulations ). YES NO WYPDES Application for Permit to Discharge Produced Water: Application for Coal Bed Methane New Discharges, Renewals, or Major Modifications, revised 04-25-07 ROCK WELL PETROLEUM, INC: 2007-12-27 / 10080010 / NEW NON-CBM: GREYBULL OIL FIELD Page 6 of 8 (06-554.DOC) Irrigation rights to use Bighorn River water downstream of the proposed outfall have been identified from a search of WSEO water rights database and are available upon request. If yes, at a minimum, the WYPDES Program requires submission of the following information: 1. Location(s) of irrigation diversions and/or sub-irrigated acreage; 2. Type(s) of Crops grown under irrigation; 3. Description of Irrigation Practices 4. A topographic map showing irrigated acreage, any structures, ownership of irrigated acreage. In addition to the minimum information described above, the WYPDES Program may require additional information should the permittee request site-specific effluent limits protective of irrigation uses. Contact the WYPDES Program for more information regarding requirements for site-specific SAR, TDS, and EC limits. 24. Provide name(s) and address(es) for all downstream irrigators between the outfalls and the mainstem. Irrigator #1 Name Irrigator #2 Name Mailing Address Mailing Address City, State, and Zip Code City, State, and Zip Code (additional spaces may be added as necessary) Only very limited historical river water quality data could be located for typical oil production water constituents for comparison to Rock Well’s effluent. To date, Rock Well has collected 2 Bighorn River water quality samples: 1 depth- and width-integrated composite sample collected from the Rt. #14 bridge downstream of the proposed discharge point, and 1 grab sample collected the same day at the proposed discharge point at the west bank of the river for comparison to the composite (Table 4 and Appendix B). The predicted resultant water quality mixture of effluent plus Bighorn River water is nearly the same quality as current Bighorn River water quality – see river water quality (Table 4) and mixing analysis (Table 5). This mixing estimate conservatively assumes the maximum concentrations from the produced water and tunnel water database (Table 3) and the minimum concentrations from the river water database beginning with 2007 samples (Table 4). The river flow rate assumed (163,385 gpm) is equivalent to the river low flow 7Q10 value (364 cfs) referenced from the Town of Greybull’s WYPDES permit No. WY0020583 already discharging to the Bighorn River downstream (north) of Rock Well’s proposed outfall. 25.
