1. Oil-fired Units Bill Maxwell EPA/ESD/CG March 5, 2002 Washington, D.C.

2. Where do we stand on oil? zProfile of the sector zStatus of the data zWhat the data tell us zWhere to go from here

3. Limitations of the profile data zData not as easy to identify as for coal units yMore multiple fueled units yNot as much segregation as to what oil is burned

4. Profile of the oil-fired sector zUsed four data files yEPA E-GRID2000 Boiler and Generator files (data for 1999) yEPA Score00 files - Emissions scorecard data for 2000 yEIA Tables 8 and 20 (data for 1999) yData posted on website as one file yDatabases do not agree 100%

5. Profile -- continued zEstimate on the order of 150 oil-fired units at 70 facilities yEstimated 137 facilities in Final Report to Congress yHas been a contraction of the sector zLocated in 18 States and the District of Columbia zSize appears to range from ~270 - ~9,000 MMBtu/hr heat input

6. Profile -- concluded zControls yFrom Final Report to Congress, ~1/3 use ESP yNo unit found with FGD system yApproximately 10-20% may use distillate oil zDual-fuel capability yDifficult to determine as the listing of fuels is not consistent from file to file yGas/oil firing significantly more prevalent than oil/coal firing

7. Status of the data zHave tests from 13 units, all residual oil- fired yInlet/outlet on 4 units x3 ESP units x1 pilot-scale FF x1 SCR yWith/without NO x control on 1 unit yOutlet only on 8 units z20 tests total y16 tests essentially uncontrolled y4 tests with PM control for metals

8. Assumptions going in zNickel is HAP of greatest concern yCAA section 112(b)(1) lists “nickel compounds” -- not individual species zFF is not realistic control for oil-fired units yPM tends to be “sticky” yFouls bags and presents safety hazard yNot suitable for MACT floor basis zLeaves ESP as only demonstrated control

9. Finding the floor zMore than 30 units in the sector so could use top-performing 12 percent of data yTop 12 percent would be top 2 units yTop 2 units are ESPs with reported PM efficiencies of 92 and 77 percent xFloor set based on performance of these units xLooking at individual runs will establish variability ySome uncontrolled units would be able to meet level established, depending on the metals content of the oil fired

10. Where we go from here zTopics for further investigation yAvailability of “low metal” oil yImpact on oil supply and quality of Phase II sulfur rules yUse of PM as surrogate for metals yFinal floor numbers zAdditional data made available in timely manner would be considered
