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

*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. Remove outfall 006, associated reservoir, and reservoir monitoring point. __________________

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 controlled by the consumptive capacity of the

reservoirs which is estimated at 1.69 MGD. The reservoirs will contain all effluent during normal operations

and will only overtop during a storm event of any magnitude.

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…”:

All reservoirs will be operated such that they contain all effluent during normal operations and will only overtop during a

storm event of any magnitude. _____________________________________________________________________________

_______________________________________________________________________________________________________

_______________________________________________________________________________________________________

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

*”Reservoir reclamation volume” is the volume of backfill and/or topsoil needed to fill reservoir upon reclamation, in cubic yards. This can also be measured in the amount of material that was excavated to

create the reservoir. 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.

TABLE 5. Assimilative Capacity Information for Direct Discharges Within Powder River Hydrologic

Basin Only*

* DIRECT DISCHARGES 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.

This table ONLY needs to be completed for applications requesting Option 2 direct discharges located within the Powder River

hydrologic basin that cannot meet Powder River ambient concentrations for TDS and sodium for all months of the year.

Assimilative capacity for monthly planned reservoir releases will be evaluated at the time that the permittee applies for the monthly

release authorization; this table does NOT need to be completed for monthly reservoir release situations.

1. List all outfalls that are requested for direct discharge:

2. Please indicate, for both total dissolved solids and dissolved sodium, the pounds per month (“credits”)

the permittee wishes to allocate to this permit (i.e. what portion of the total assimilative capacity

available to the permittee will be issued to this permit for each month?).

Constituent Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

TDS (lb/mo)

Dissolved

Na (lb/mo)

3. Please indicate, for each month of the year, what the expected water quality concentrations for TDS

and dissolved sodium (in mg/l) and the expected flow volumes (in millions of gallons per month), will be

for this facility:

Constituent Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

4. Please provide a brief description of the source of information used to determine concentrations and

flow volumes listed in item #3 above:

5. Does the applicant intend to treat water at this facility to meet the concentrations provided in item #3

above? □ Yes □ No

6. Please indicate, for the months of August and September when no assimilative capacity is available to

any operator, how the applicant will manage water such that no additional salt loads are contributed

to the Powder River (i.e. contain all discharges in reservoir(s) up to storm event, treat effluent from

direct discharge outfalls to Powder River ambient concentration, cease discharge from these outfalls

for these two months, etc.):
