Agenda for today (and SBA comments that are referenced)

<<SBA Comments _DRAFT FINAL RICE SI RULE_ August 4 2010.doc>> I’m suggesting this for the agenda for 2 PM I. Cost/Ton 4 SRB Engines Area Sources 500 or 750 or 1000 HP Cutoff? (SBA Comment III) Previous cutoff was $34,000/ton (500 HP), should EPA raise this to $93,000/ton? July 27 draft memo says $62,000/ton was excessive. At 750 HP, cost/ton is now $68,000. II. Cost/Ton 4SRB Major Sources - 300-500 HP – Regulate with or without NSCR? (SBA Comment IV) Cost/Ton now $62,000 (500 HP) $92,000 (300 HP). Cost/Ton 4SLB Area Sources - 500 or 750 or 100 HPCutoff? (SBA Comment II – last paragraph) Should the cutoff remain $20,000/ton? (now 750 HP). III. 4 SLB MACT Floor – 300-500 HP – Should it be set with controlled or uncontrolled engines? What does the Bricks decision require a change to the setting of the floor? How does this satisfy the “logical outgrowth” test? (SBA Comment II)

IV. 4SRB MACT Floor - 100-300 HP - 10.3 ppm 99% Does not reflect variability, particularly for engines under lower loads 99% UPL should be adjusted to reflect data, or adjust data to reflect additional tests with lower loads. (SBA Comment V) V. Limited Use Engines (SBA Comment VIII) Other Interagency Comments/Issues Not Addressed above: Additional Working Comments: Cost of Control (page 1) Annual Testing Costs (page 2) – Did EPA really propose CPMS for area sources? Not in proposed Table 5. Working Comments: Irrigation Engines (page 2) Military Engines (page 3) if DOD on call Rural Area Sources (if desired) page 4 Another Issue – Post – Call - Catalyst Replacement/Testing OECA Protocol(See attached file: SBA Comments _DRAFT FINAL RICE SI RULE_ August 4 2010.doc)
