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

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. Outfalls 001 – 006 will discharge into four (4) on-channel reservoirs; the lowermost reservoirs will contain CBNG produced water during ‘dry’ operating conditions. Vanguard is authorized to release produced water from upstream on-channel reservoirs to the lowermost on-channel reservoirs identified in question 10c. Discharge from the lowermost on-channel reservoirs is allowed with prior written authorization granted by the WYPDES program for a reservoir release, in association with use of assimilative capacity credits for the Powder River Basin.

*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…):

Update reservoir information, as shown on Tables 1A/1B/3/4.

Update the MW1 and MW3 groundwater monitoring wells, as shown on Tables 1A/1B.

Update STR1 stream monitoring point, as shown on Tables 1A/1B.

Update R1, R2 and R4 reservoir monitoring stations, as shown on Tables 1A/1B.

Update the Downstream (DPR), Tributary (TRIB1) and Upstream (UPR) Water Quality Monitoring Stations to more field accessible locations, as shown on Tables 1A/1B.

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

The maximum anticipated discharge rate from this facility is 0.1617 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, Vanguard anticipates containment of CBNG produced water from outfalls 001 – 006 within four (4) on-channel reservoirs; the lowermost reservoirs will contain effluent during ‘dry’ operating conditions and will only overtop naturally during a storm event of any magnitude. Vanguard is authorized to release produced water from upstream on-channel reservoirs to the lowermost on-channel reservoirs. Discharge from the lowermost on-channel reservoirs is allowed, during ‘dry’ operating conditions, with prior written authorization granted by the WYPDES program for a reservoir release, in association with use of assimilative capacity credits for the Powder River Basin.

The upstream on-channel reservoirs that are allowed to discharge are as follows: Mary L. Hey, P14-2-47-76 and P23-1-47-76.

The lowermost on-channel reservoir is as follows: Mankin.

Please note that Vanguard will monitor flow rates and alter discharges as necessary to meet the requirements of this permit.

Please see Table 3: Reservoir Information for additional details.

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 pertinent to the water management strategy of this facility. d. Reservoirs

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 at 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 at this facility.

Please see the attached permit renewal map for the remaining items listed above.

(If any of the above are not applicable please indicate in the description and include a brief explanation as to why the item is not applicable.)

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.

Produced water is discharged slowly through a vertical, large diameter riser pipe and allowed to flow down the side of the corrugated pipe to dissipate energy. The discharge water passes over cement aprons and/or rip-rap placed at a gentle slope prior to entering the receiving water/reservoir.

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 necessary to meet the water quality standards and effluent limits. However, passive treatment methods such as aeration and settling may be implemented to reduce concentrations of trace 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 outfall locations were determined by field personnel using a handheld GPS unit with an accuracy of generally 60 feet or better. The outfalls are located on ephemeral stream channels in locations where the discharge water will benefit livestock and wildlife. Outfalls 001 – 006 are shown 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.

** 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.

Table 4 - Bonding Information: WY0055638 - Pumpkin Creek POD II North

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.
