 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  (non-
selective 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?
