D/F revisions which included startup and shutdown limit 2. Monthly monitoring is increased to 10 minutes on MHOs 3. Affirmative defense f or exceedance of emission limit during malfunction 4. Clinker Storage Pile Requirements All other standards become effective in 2013 The monitoring question I had was that the rule using the following language for each monitor " Compliance with the X XX emissions standard must be determined based on the first 30 operating days you operate a XXX CEMS." This language suggest that if a source installs a CEM before 2013 it must comply after 30 operating days. While we have discussed this and my understa nding is that a source that installs a PM CEM for example in 2011 will not have to comply until the emission rate standard becomes effective in 2013. This needs to also be cleared up because the rule is confusing.

Dear Andy: I will get back to you with a definitive answer hopefully today. On that note - I know the open clinker piles are the main issue - but I also received calls on the changes to testing and monit oring procedures

- notably the opacity monitoring. Though this is not a big deal it does require that current procedures be changes to comply. Can you point me to specific changes (i.e. the paragraphs) where we might want to at least consider moving the compliance date? I am cc'ing Hector on this because he called me at one time on the testing procedures issue. Keith W.

Peter, Checking in on the compliance deadline matter addressed in the attached letter, which we discussed last week, and wondering when you will be in DC next and whether we could sit down again for some discussion. Thanks, AndyAndrew T. O'Hare, CAE
