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 HP
Cutoff?

(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)
