### , Ms. Lozano returned my call and confirmed the DMR discharge data. The 10 mg/L sulfide

discharges for June and December are correct . She stated that the facility’s permit has a limit for sulfate but not

for sulfide discharges. The 10 mg/L values are monitoring data. She stated that she would look for the facility’s

permit to determine if it is a CBM facility and would get back to me. She also requested further details on our

request in an email. Please see attached email correspondence.Need to return call by / at/between and

Subject: FW: Marathon Oil Maverick Springs DMR Data

Kim,

Attached is the information on Marathon Oil, WY0000779 that I was able to locate in our records files. Also included is

the pull from the ICIS database. I’m not sure if this prov ides any clarity on the sulfide question.

Please let me know if you have additional questions. I believe the permit is currently being drafted, but I am uncertain of

the expected publication date. Colleen Rathbone, NPDES manager, may have more informa tion on any pending actions,

she will be back in the office on January 2 nd

.

Thanks, VelRey

Dear Ms. Lozano:

Thank you for your time on the phone today. Eastern Research Group, Inc. (ERG) under EPA Contract No. EP

- C

- 12

- 021, is e

- mailing you to request information for Maverick Spring Tank Battery in Cody, WY (WY0000779). See below

for background on what the information is used for.

EPA reviews publicly

- available DMR data to fulf ill its review obligation under Section 304(b) of the Clean Water Act.

The CWA requires EPA to annually review and, if appropriate, revise its water pollution control technology

- based

regulations, called "effluent guidelines," that limit the discharge of p ollutants to waters of the U.S. from various categories

of industrial facilities. EPA is currently conducting its 2015 annual review of existing effluent guidelines and potential

industrial guidelines which may need to be included (see http://www.epa.gov/guide/304m/ for further information). EPA

will discuss this review and the results in its 2015 Effluent Guidelines Program Plan scheduled for publication in the

Federal Register sometime in 2015 or 2016. As part of the 2015 annual review, EPA is evaluating the data in discharge

monitoring reports from 2013.

Thank you for confirming the DMR data for sulfide discharges for the facility over the phone. It would be appreciated if

you could provide a sh ort description of the facility or a copy of the facility's current NPDES permit if available.

Please call me at (517) 515

- 1721 if you have any questions. If you would like to speak directly with EPA regarding this

request, you can contact William F. Sw ietlik of EPA's Office of Water/Engineering Analysis Division by phone at (202)
