7.a. If applying for outfalls under Option 2, are any of the proposed Option 2 outfalls DIRECT DISCHARGES*that

would require the use of assimilative capacity credits for salt and sodium in the Powder River?

YES NO

CBNG water is not expected to overflow the lowermost reservoir, Brush Hog, with the exception of a precipitation event. Storm Cat is committed to full containment of produced water within the Brush Hog reservoir during dry operating conditions.

If “yes”, please complete Table 5.

*DIRECT DISCHARGE means those discharges that are not or are only partially contained within reservoirs. Discharges to reservoirs that only overtop and spill during storm events are not subject to assimilative capacity requirements. Direct discharges that can meet Powder River ambient concentrations for TDS and sodium are also not subject to assimilative capacity requirements.

7.b. If applying for outfalls under Option 2, is it possible that INTENTIONAL RESERVOIR RELEASES* will be requested for any of the reservoirs receiving CBM discharges under this permit?

YES NO

Storm Cat may intentionally release stored water, at a future time, from the lowermost on-channel reservoir Brush Hog, in accordance with the WDEQ reservoir release program to allow additional flexibility with their water management. Storm Cat is also committed to full containment of produced water within the Brush Hog reservoir during dry operating conditions.

*INTENTIONAL RESERVOIR RELEASE means purposeful and intentional reservoir releases (opening a valve or pumping out a reservoir) to provide freeboard within a reservoir. Discharges that occur solely in response to storm events are not considered intentional reservoir releases, and do not require assimilative capacity credits. Intentional reservoir releases are authorized on a case-by-case basis and require WDEQ approval above and beyond a WYPDES surface discharge permit (authorization application form available on WDEQ website).

8. If submitting a major modification or permit renewal, please describe all requested permit modifications (i.e. add 2 outfalls, add 23 wells, move outfall 001 500 feet…):

1. Updated well information per WOGCC records. 2. Updated immediate receiving stream for outfalls 002 and 005; please see Table 1A.




9. Name(s) and mailing address(es) of owner(s) of the surface rights on whose land the discharge occurs (in cases where the land is owned by the state or federal government but surface rights are leased to a private individual, provide lessee’s name and address)

Landowner Name Eric E. & Marie M. Rule Agreement Trusts ATTN: First Interstate Trust Dept. Mailing Address P.O. Box 2007 City, State, and Zip Code Sheridan, WY 82801

10a. Please provide the maximum anticipated discharge rate, in million gallons per day (MGD), from this facility:

The maximum anticipated discharge rate is 0.05 MGD. 10b. Does this facility rely on containment in reservoirs (of any type) as part of the water management strategy?

YES NO

10c. If NO is checked above, please proceed to item #11. If YES is checked above, the permittee is required to conduct an internal evaluation of the ability of the reservoir(s) at this facility to contain discharges. Based on the results of this evaluation, please describe the ability of the reservoir(s) at this facility to contain effluent and surface run-off from precipitation events. If there are multiple reservoirs at this facility which have different reservoir containment capabilities, please describe separately, identifying reservoirs using reservoir name. For example, “Reservoir A will contain all effluent and will only overtop during a storm event of any magnitude; Reservoir B will contain all effluent plus surface run-off from up to the 50 year/24 hour storm event, etc…”:

Based on the results of an internal water balance evaluation, Storm Cat anticipates full containment of CBNG effluent during dry operating conditions. Uppermost reservoir Stallion cascades to lowermost reservoir Brush Hog, which is not expected to overflow with the exception of a precipitation event.

The internal evaluation does NOT need to be submitted to the WYPDES Program as part of this application. By completing item 10b and signing this application, the permittee certifies that the reservoirs at this facility are capable of meeting the containment abilities which have been provided. The WYPDES Program will use the information provided above to determine the appropriate reservoir containment requirements that will be established in the permit. If reservoir containment requirements established in the permit are not met, this may constitute a violation of the permit, which is subject to full enforcement by the WYPDES Program.

11. Attach a description and a clear, legible, detailed topographic map of the discharging facility. Include the

following: a. A legend b. Well locations c. Ponds – Not applicable. There are no ponds associated with this facility. d. Reservoirs e. Stock tanks – Stock tanks are not pertinent to the water management strategy of this facility. f. Discharge points (outfalls) g. Immediate receiving streams h. Water quality monitoring stations i. Irrigation monitoring points j. Location of nearest downstream irrigator k. Section, Township, and Range information l. If proposing to use class 4C off-channel pits (option 1A), include footprint outline of the proposed pits. To

denote setback distance, include a distance marker from closest side of pit to the nearest water feature, floodplain, or stream alluvium. Identify latitude and longitude in decimal degrees (using a minimum of 6 decimal places) for each end point of the setback distance marker. – Off-channel pits are not being used with this facility.




m. If proposing discharge to a headwater reservoir or to a playa lake (option 1B), include footprint outline of the proposed impoundment(s). See page 1 of the application form for option 1B impoundment siting requirements. To denote setback distance from alluvial floodplain areas, include a distance marker from closest side of the impoundment to the nearest floodplain, or stream alluvium. Identify latitude and longitude in decimal degrees (using a minimum of 6 decimal places) for each end point of the setback distance marker. Headwater reservoirs and playa lakes are not being used with this facility.

Please see the attached permit renewal map.

12. 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 outfalls have been constructed on topography that gradually slopes towards the receiving channel/impoundment structure. Erosion control such as rip-rap and geotextiles will be used as necessary.

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.

No active water treatment is planned. Produced CBNG water will be discharged into and contained within on-channel reservoirs. The outfalls will be constructed in a manner that aerates CBNG water to help induce precipitation of some dissolved metals.

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 outfalls associated with this renewal have been constructed per the impoundment structure locations and topography. Site coordinates were obtained using a hand-held GPS unit with accuracies ranging from 20 to 60 feet. Outfalls 002 and 005 are represented in their as-built locations.

15. Complete the attached Table 1. Provide all the information requested in the table for each proposed discharge point or monitoring point. If proposing changes (a major modification) to an existing facility, clearly indicate the desired changes on the table. Additional tables may be attached. Use the format provided. Option 2 permits, except those located in the Belle Fourche or Cheyenne River Basins, must include water quality monitoring station locations. Option 1B headwater reservoir discharges (reservoirs other than playa lakes capable of 50 year, 24 hour stormwater runoff containment) must include flow monitoring station locations. Option 1A and 1B permits must include containment unit monitoring station locations. Information related to reservoirs is only required if the facility’s water management plan includes reservoir containment.

Please see attached Tables 1A and 1B: Outfall Information. 16. Complete the attached Table 2. Provide all the information requested in the table for each well associated with

this proposed discharge authorization. If proposing changes (a major modification) to an existing facility, clearly indicate the desired changes on the table. Additional tables may be attached. Use the format provided.

Please see attached Table 2: Well Information. 17. Complete the attached Table 3. Provide all the information requested in the table for each reservoir proposed for

containment of CBM produced water. Specified locations refer to the approximate center of the reservoir. If proposing changes (a major modification) to an existing facility, clearly indicate the desired changes on the table. Additional tables may be attached. Use the format provided. Information related to reservoirs is only required if the facility’s water management plan includes reservoir containment.

Please see attached Table 3: Reservoir Information.




18. Complete the attached Table 4. Provide all information requested in the table related to reservoir bonding requirements for each reservoir proposed for the containment of CBM produced water. If proposing any changes (a major modification) to an existing facility, clearly indicate the desired changes on the table. Additional tables may be attached. Use the format provided. Information related to reservoirs is only required if the facility’s water management plan includes reservoir containment.

** Reservoir constructed/upgraded information relates to the September 2005 memo in which topsoil stockpiling is required for the new construction or the upgrade of an existing reservoir, as defined by embankment enlargement or spillway excavation. The installation of a drainpipe does not require topsoil stockpiling.

A Yes response in this column represents that the reservoir has been constructed prior to September 2005, or a reservoir constructed before September 2005 that needs an upgrade that does not require the stockpiling of topsoil, e.g., drainpipe installation.

A No response in this column represents that the reservoir is not constructed, the reservoir requires upgrades which will require topsoil stockpiling on site, or the reservoir was constructed after September 1, 2005.

Please check only one "reservoir reclamation volume" box for each reservoir

* Reservoir Reclamation Volume is the volume of the reservoir embankment with topsoil. The reservoir may have been created by an embankment that is either a cross valley/draw fill or an excavation with the embankment on 3 or 4 sides. During reclamation, the embankment is usually placed in the location where earth was borrowed to create the embankment.

Please note that reservoir information is not required if reservoir containment is not part of the facility's water management plan - for instance, information about existing incidental downstream reservoirs is not required.
