General Subject: 2013 DMR Sulfide Discharges for Maverick Spring in Cody, WY

TOPICS DISCUSSED AND ACTION TAKEN

Region 8 General Number: 303-312-6312

On December 18th, I called VelRey Lozano at EPA Region 8 and left a message. She returned my call and 

asked for details on what I was looking for; then stated she would call me back.

On December 19th, 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.

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 provides 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 information on any pending actions, 

she will be back in the office on January 2nd.

Thanks, VelRey

Subject: 2013 DMR Clarification for Sulfide Discharges

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 fulfill 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 pollutants 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 short 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. Swietlik of EPA's Office of Water/Engineering Analysis Division by phone at (202) 

566-1129 or by email: swietlik.william@epa.gov.
