Rebecca... thanks. This V2 of the modeling protocol looks good. Let’s move forward.

Updated
BART Modeling Protocol (draft v2 3-28-13 ras)

Apply “Modeling Protocol for Washington, Oregon and Idaho: Protocol for the Application of 

the CALPUFF Modeling System Pursuant to the Best Available Retrofit Technology (BART) 

Regulation (7/21/06).”

The CALPUFF modeling system will be applied using the exact same meteorological data set 

(2003-2005), model versions, and options as specified in the original Protocol used in the 

February 2008 “BART Determination Modeling Analysis, Tesoro Anacortes Refinery.” The 

following results will be summarized for each Class 1 area within 300 km radius of Tesoro: 

1. Contrasting the number of days with predicted changes to the haze index greater than 

0.5 dv

2. The 98th percentile change to the daily haze index

3. The maximum change to the daily haze index. 

The design day extinction budgets will also be presented for each Class I area, emission case, 

and year. 

Model the following cases: 

1. Baseline

2. EPA BART

3. Tesoro’s “Better-than-BART” Proposal

Baseline: 

 Include all sources involved in the EPA BART and Tesoro “Better-than-BART” cases as listed 

in Attachment 1.

 Apply estimated maximum 24-hour emission rates during 2004-2006 for each pollutant for 

all EPA BART and Tesoro “Better-than-BART” sources. (*)

 Apply meteorological (met) conditions previously prepared during initial BART modeling 

(2003-2005).

 Post-control for SO2 and PM emission rates will be used for F-302 and F-304 to account for 

the installation of the Flue Gas Scrubber at the CCU in 2005. This will remain constant for all 

three cases.
EPA BART:

Using the “Baseline” furnace firing rate, apply the emission reduction benefit of: 

1. BART controls (as agreed to in Ecology’s BART Order #7838)

2. EPA additional BART NOX controls at the following sources: 

F-6650, F-6651, F-6652, F-6654 and F-304.

Tesoro “Better-Than-BART”:

Using the “Baseline” furnace firing rate, apply the emission reduction benefit of:

1. BART controls (as agreed to in Ecology’s BART Order #7838) 

2. Tesoro RFG Project to non-BART sources: 

F-101, F-102, F-301, F-6652, F-751, F-752.

(1) F-302 and F-304 share a common stack. F-304 contributes ~ 58% of the total FGS NOX and 50% of the total FGS SOX and PM.

(2) For the purpose of comparing EPA BART and Tesoro Better-than-BART, the baseline 24-hour maximum emission rate is being estimated 

using the maximum monthly emission rate between 2004 - 2006. Furthermore for the non-BART sources F-751 and F-752, the maximum 

monthly period was selected from months whereby only RFG was burned (no oil burning).

(3)Tesoro is subject to a federally enforceable RFG H2S limit of 1,000 ppm, 365-day rolling average, applied in the Ecology BART Order #7838. 

(4) The original BART Modeling 24-hour emission rates for the Flare X-819, Cooling Water #2, Cooling Water #2A will be applied to all three 

modeling cases due to the relatively low emission rates and that there are no proposed emissions changes in either the EPA BART or Tesoro

Better-Than-BART scenarios.
