General Subject: 2009 TRI Dioxin Releases and Distribution 

TOPICS DISCUSSED AND ACTION TAKEN 

On January 10, 2011, I called Suncor Energy to speak with William Buckalow regarding 2009 TRI dioxin 

discharges and corresponding dioxin distribution. The operator stated that Mr. Buckalow is not longer with the 

company and transferred me to Karen McGae. I was unable to leave a message for Ms. McGae. 

On January 12, 2011, I called Suncor Energy again; however, was unable to leave a message. 

On January 18, 2011, I called Suncor Energy and left a message for Lucy S. On January 19, 2011, Tony 

Comgram left me a message asking me to return his call to discuss 2009 TRI data. 

On January 20, 2011, I returned Mr. Comgram’s call to discuss dioxin discharges reported to 2009 in TRI. Mr. 

Comgram stated that the facility recently had discussions with EPA Region 8 (Contact: Barbara Conklin) and 

did some speciation testing regarding dioxin. Mr. Comgram stated that he would e-mail me some helpful 

information regarding the dioxin releases. 

On January 25, 2011, Mr. Comgram left me a message stating that he sent the dioxin speciation data and the 

correspondence with EPA Region 8 regarding dioxin emissions via e-mail. Please see the following e-mail and 

attached documents.

Greetings Elizabeth. 

In response to your telephone request, I am providing two documents that I hope are responsive. 

The first is recent (July 2010) dioxin-furan analysis performed on the refinery treated process wastewater (reference NPDES permit CO-0001147, 

Outfall 002). The additional document is a copy of correspondence with Ms. Barbara Conklin of USEPA Region 9 regarding air emissions 

questions she had relevant to RY 2008 TRI. 

Please let me know if you need further information, and be advised that this most recent dioxin-furan speciation information will be utilized in 

preparation of the RY2010 TRI for the referenced facility. 

Regards, 

Tony Congram

Subject: RE: Reporting of Dioxin Compounds on 2008 TRI 

Good afternoon Barbara. 

I apologize for the delay in response on this matter. 

Please note that the emission factor used at the Suncor (and legacy Conoco) Commerce 

City Refinery since 2000 is based on emission factor data from a 1991 California Refinery 

stack test (performed by Radian) on a semi-regenerative catalytic reforming unit similar 

to the technology of the Suncor unit. Data from this test is presented as part of Table 5-

2 in the following EPA document: “An Inventory of Sources and Environmental Releases

of Dioxin-Like Compounds in the United States for the Years 1987, 1995, and 2000", 

EPA/600/P-03/002F, November 2006. 

It appears that high-confidence emission factors for this particular application are not 

readily available. Any information on updated emission factors from EPA (or other 

sources) that could provide improved emissions estimates for semi-regenerative catalytic 

reformers would be greatly appreciated. 

Please feel free to contact me at 303-286-5890, or acongram@suncor.com. 

Regards, 

Tony Congram

Anthony, 

Thank you for your letter dated June 4, 2010, from Jonathan Matt. Our 

headquarters office is checking to see if there are any applicable 

emission factors for reporting the individual members within the dioxin 

and dioxin-like compounds category. What is the source of the current 

emission factor you are using?
