February 10, 2012 Mr. Roland Peterson Wyoming Department of Environmental Quality Water Quality Division 122 West 25th Street, Herschler Building, 4-W Cheyenne, Wyoming 82002

RE: WY0003140 Homestead Field Disposal, WYPDES Permit Renewal Application Legacy Reserves Operating, LP

Dear Mr. Peterson, Legacy Reserves Operating, LP (Legacy) respectfully submits the enclosed WYPDES renewal application for its WY0003140 Homestead Field Disposal oil facility. Enclosed for your consideration are the following:

• WYPDES Permit Renewal Application for Oil and Gas Discharge • Flow Data Table • Representative Water Quality • MSDS Sheets • Facility Diagram • Permit Application Map

Under this permit, Legacy will pipe produced water from up to four (4) production wells completed in the Tensleep formation. The production stream from the associated wells is piped into the tank battery in a closed-loop-system. The production stream first passes through a line heater that is used during winter months to heat the production stream for easier separating. The production stream then proceeds to a free-water knockout (FWKO). From the FWKO, the production stream is piped to two (2) heater treaters that separates the stream into two separate streams. The first stream is produced water that is sent to a 400 bbl produced water tank, and the second stream is oil that is routed to seven (7) 400 bbl storage tanks. The produced water from the 400 bbl produced water tank is discharged into a netted skimming pond through a water treatment cascade unit, which removes H2S gas. The produced water is then gravity fed into a second skimming pond that discharges into a pond via a second water treatment cascade unit to remove any additional H2S gas. From the pond, the produced water is gravity fed into a lower pond that discharges to Sage Creek (2AB) through outfall 001. With this renewal, Legacy would like to update the qtr/qtrs for outfall 001 and DMP1 to match their as-built and field verified locations, respectively. If you have any questions, please contact me at (307) 587-7232 or sbliss@legacylp.com; you may also contact Bret Bergstrom of InterTech Environmental & Engineering, LLC at (307) 742-4991 or bretbergstrom@cbmainc.com.

14. Were the above analyses collected from this facility (referenced in item 3)?

YES NO Sample collected from outfall 001.

If no, describe origin of samples including well name, location, depth, geologic formation, field, and date sample was analyzed:

15. For new facilities, provide the expected (estimated) flow rate from each outfall in barrels per day and million gallons per day, and provide the rationale behind the flow rate estimate. Not applicable, this is an existing facility. For existing facilities, provide actual flow data from each outfall within the last six months. The actual maximum flow rate from this facility during July – December 2011 is 4,071 BPD and 0.171 MGD. Please see attached flow data table for details.

Will discharge be continuous or intermittent?

If the discharge is to be intermittent the following information for each outfall shall be provided: (I) Number of times per year the discharge is to occur. (II) Anticipated duration of each discharge. (III) Anticipated flow of each discharge. (IV) Months in which discharge is expected to occur.

16. Are any of the required chemical constituents in the laboratory analysis present in concentrations above Wyoming Water Quality Standards or limits as identified in the third column in Table 2, page 5?

YES NO

If the answer to question # 16 is yes, answer 16a.–16.c below. If no, proceed to question 17.

a. Which constituents? - Cadmium, Dissolved - Oil and Grease - Sulfide-Hydrogen Sulfide b. Has this constituent been addressed in the response to question 10? Yes

c. Describe how the exceedance was addressed. - Waiting on resample results for Dissolved Cadmium. - The Oil and Grease exceedance can be attributed to one of the heater treaters going out of service prior to sample collection. This issue has been addressed and both heater treaters are operating properly. A second sample with Oil and Grease has been attached to show concentrations prior to heater treater breaking down. - There are two water treatment cascade units on-site to help reduce Sulfide-Hydrogen Sulfide concentrations in the water.

17. Will blending of fresh water with produced water be used as a treatment option?

YES NO If the answer to question # 17 is yes, answer 17a.–17.c below. If no, proceed to question 18.

a. What is the anticipated blending rate of fresh water and produced water? ____________________________ Be advised that permit will require water quantity and quality monitoring before and after blending occurs. Also, an automated shutdown system must be installed and maintained on site that terminates the discharge of produced water in the event of the shutdown of the fresh water supply.

b. Provide confirmation from the State Engineer’s office of fresh water use.

c. What is source of fresh water to be blended? No surface water source is allowed.

18. For facilities new after January 1, 1998: Is there active irrigation in the drainage downstream of the discharge? (Please note that this response includes both artificially and naturally irrigated bottomlands.)

Not Applicable (Facility is pre-1998) YES NO

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. 19. For facilities new after January 1, 1998: Provide name(s) and address(es) for all downstream irrigators between the outfalls

and the mainstem. Not Applicable (Facility is pre-1998) 20. 40 CFR Part 435 Subpart E requires that the permittee document agricultural and wildlife uses of produced water. Provide

documentation that the produced water will be used for agriculture or wildlife during periods of discharge. Agriculture and wildlife use includes irrigation, livestock watering, wildlife watering, and other agricultural uses. Agricultural and wildlife use documentation includes (but is not limited to) a certified letter from a landowner(s), a formal written statement from a state, federal or local resource management agency, or a formal written statement with supporting documentation from a natural resources or environmental professional accompanied by the credentials of the natural resources or environmental professional. Agriculture and wildlife use documentation must be provided for each outfall included in the application. Agricultural and wildlife certification must be submitted for each outfall’s discharge, and must have original signatures.

Facilities permitted prior to June 10, 2002 are exempt from the above requirement. The Wyoming Game and Fish Department has determined that discharges of produced water from WYPDES-permitted oil production units in Wyoming, existing as of June 10, 2002, are being used to enhance wildlife propagation and habitat.

This facility was WYPDES or NPDES permitted prior to June 10, 2002 Documentation of beneficial use is enclosed

21. Provide a listing of all active permits or construction approvals received or applied for by the applicant for the site described

in this permit application in accordance with Chapter 2, Section 5.(a).(v). T. of the Wyoming Water Quality Rules and Regulations.

This is the only active permit associated with this facility. ___________________________________________________________________________________________
