# 2009 TRI Dioxin Releases and Distribution



# TOPICS DISCUSSED AND ACTION TAKEN

On January 10, 2011, I called Suncor Energy to spea k with William Buckalow regarding 2009 TRI dioxin discharges and corresponding dioxin distribution. T he operator stated that Mr. Buckalow is not longer with the company and transferred me to Karen McGae. I was un able 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 lef t a message for Lucy S. On January 19, 2011, Tony Comgram left me a message asking me to return his c all to discuss 2009 TRI data.

On January 20, 2011, I returned Mr. Comgram’s call to discuss dioxin discharges reported to 2009 in TR I. Mr. Comgram stated that the facility recently had discu ssions with EPA Region 8 (Contact: Barbara Conklin) and did some speciation testing regarding dioxin. Mr. C omgram 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 e missions via e-mail. Please see the following e-mai l and attached documents.From: "Congram, Anthony (Tony)" <ACongram@Suncor.com>

Greetings Elizabeth.

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

The first is recent (July 2010) dioxin-furan analys is performed on the refinery treated process wastew ater (reference NPDES permit CO-0001147, Outfall 002). The additional document is a copy of correspondence with Ms. Barbara Conklin of USEPA R egion 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 fa cility.

Regards,

Tony Congram 303-286-5890

Sent: Monday, June 21, 2010 12:47 PM To: 'Conklin.Barbara@epamail.epa.gov' Cc: Christopher, Jay Subject: RE: Reporting of Dioxin Compounds on 2008 TRI

Good afternoon Barbara.

I apologize for the delay in response on this matte r.

Please note that the emission factor used at the Su ncor (and legacy Conoco) Commerce City Refinery since 2000 is based on emission facto r data from a 1991 California Refinery stack test (performed by Radian) on a semi-regenera tive catalytic reforming unit similar to the technology of the Suncor unit. Data from th is 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 t he Years 1987, 1995, and 2000 ", EPA/600/P-03/002F, November 2006.

It appears that high-confidence emission factors fo r this particular application are not readily available. Any information on updated emis sion factors from EPA (or other sources) that could provide improved emissions esti mates 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 membe rs within the dioxin and dioxin-like compounds category. What is the source of the current emission factor you are using?
