Melanie: I have my Air Permit program staff working on this. They are

checking to see if we have any test results for engines in this size category

and have indicated they can have the information pulled together by Oct 2nd.

I hope this timing will work for you.

Subject: RE: FW: Status: Alaska rural utility NSPS engine comments

Actually there is something I can ask, although it is not really related to

the amendments for facilities in Alaska - one of the aspects of the CI NSPS

that we are looking at is the PM emission limits for diesel engines with a

displacement greater than 30 liters/cylinder. Back when we were first writing

the NSPS for diesel engines we were sent some permits for a facility in

Alaska, the NJUS Snake River Power Plant expansion, and also there was some

mention that there was a similar project for the City of Unalaska. Do you
know if these facilities were ever constructed and if so has there been any PM

testing done for the engines at the facilities or any other facilities with

engines with a displacement greater than 30 liters/cylinder?

Thanks,

Hi,

I'm assuming you are talking about the comments in the 10/31/08 letter to

Jaime? We are working on a revision to the NSPS for CI engines that would

include amendments for engines used in rural areas of Alaska.

These amendments should be proposed in the next few months.

Melanie: Wayne Elson suggested that you were the person replacing Jaime Pagan

on this issue. If there is any status update you can provide (see below), I

would appreciate it! Thanks!

Jaime: I received a call today from a rural paper (Alaska Dispatch)

related to the ultra low sulfur diesel transition in rural Alaska. The

reporter’s name was Rena Delbridge and she may give you a call as well.

I did not know what the status was for EPA’s response to the rural utility

transition comments that DEC sent you on the New Source Performance Standards

for stationary compression ignition internal combustion engines. Is there any

update from your end on how EPA may handle those transition comments? Thanks!
