Heather:

Here is a breakdown of SWCAA's spark ignition engines. If you want more

details about each engine, view the attached pdf.
Minor Sources:

Non-Emergency Engines >500 hp: 1 w/NSCR Non-Emergency Engines <500 hp: 2

w/NSCR, 1 no catalyst

Emergency Engines > 500 hp: 2 no catalyst

Emergency Engines < 500 hp: 42 w/o catalyst, 1 w/NSCR

Title V:

Non-Emergency >500 hp: 2 2SLB w/o catalyst

Emergency >500 hp: 2 w/o catalyst

Subject: Request for info related to control of existing rich burn engines

Hi, I have a request from headquarters related to the NESHAP rule making

for existing spark ignition engines, If you know of others who wold have a

better handle on the current landscape for rich burn spark ignition

(gas-fired) engines in terms of how many of the existing engines that are

already in use have emission controls (non-selective catalytic reduction or

NSCR) installed please let me know who that would be. Rich can you forward

this to folks in the WA permit writers group who might be good contacts that

I did not include?

Headquarters is trying to get a handle on what the current landscape is for

rich burn spark ignition (gas-fired) engines in terms of how many of the

existing engines that are already in use have emission controls (nonselective catalytic reduction or NSCR) installed because they are looking at

what the impacts of the upcoming final NESHAP for existing spark ignition

engines would be if controls were required for those engines. It would be

helpful if we had some idea of how many of them already have these controls

even in the absence of the NESHAP. The engines we'd be concerned with are

those that are <500 HP at major sources of HAP and any HP at area sources of

HAP, since we already have limits on the ones that are >500 HP at major

sources.

Do you know of any estimates of how many of these engines are controlled

for the states in Region 10?
