Sergio Ibarra: 801-366-2086, Sergio.ibarra@tsocorp.com

I called Ms. Bujdoso on December 22nd and left a message. 

I called Ms. Bujdoso on December 30th and left a message. 

On January 5th, Sergio Ibarra returned my call. He stated that the facility uses sampling data to calculate the 

hydrogen sulfide discharges. They based the calculations off a white paper; they have received limited guidance 

on calculating hydrogen sulfide discharges. A consultant to the company developed the documentation to 

calculate the H2S discharges and the Tesoro corporate office agreed with the approach. Mr. Ibarra requested an 

email to confirm the data and any additional questions we have. Please see attached email communication. 

[Note: we never received a response from this facility.]

Subject: 2013 Clarification for Hydrogen Sulfide Discharges

Dear Mr. Ibarra:

Thank you for your time on the phone yesterday. Eastern Research Group, Inc. (ERG) under EPA Contract No. EP-C-12-

021, is e-mailing you to request information for Tesoro Refining in Salt Lake City, UT. See below for background on 

what the information is used for.

EPA reviews publicly-available discharge monitoring report (DMR) and toxic release inventory (TRI) 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 to the 2013 TRI and needs further information to complete 

the review. Specifically, we would like to clarify the amount of hydrogen sulfide releases reported to the 2013 TRI from 

the Tesoro facility. Please confirm/review the following data and questions below.

1. Please confirm the pounds of hydrogen sulfide released in 2013: 25,000 pounds

2. As discussed on the phone, the facility uses sampling data with guidance from a white paper to calculate the hydrogen 

sulfide load reported to TRI. Please provide any additional details available on how the hydrogen sulfide load is 

calculated, including the source of the hydrogen sulfide discharge and monitoring data if possible. 

We appreciate your help in interpreting TRI data correctly. If you have any questions regarding this request, please call 

me at (517) 515-1721. If you would like to speak directly with EPA regarding this request, you can contact William F.
