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.

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 youknow 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?

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! Alice Edwards From: Edwards, Alice L S (DEC) Sent: Tuesday, September 08, 2009 2:51 PM To: pagan.jaime@epa.gov Cc: Edwards, Alice L S (DEC) Subject: Status: Alaska rural utility NSPS engine comments 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!
