RE: coke model files have gone to EPA division QA


David  -  Thank you and everyone for careful scrutiny of the model file. The internal QA found the ethylene dichloride duplicates so we've taken care of that. We are waiting for the revised model file ourselves. When we get it we will send you all a copy. There may be other changes after first cut at the risk modeling by Matt and we will keep you posted on those as well. When the model file is firm we will send you a copy (if changed) and also post it to the coke NESHAP page on epa.gov.

We need to wait for Matt to get back to see when he can be ready to meet. I will check with Chris Owen today to see if he will be ready later next week. T could be that Chris is the lead person on the buoyancy analysis. Im not sure how they have divided the work. I will ask that today also.

Thanks again for your help on this.

Thanks again for the update, Donna Lee.

We still have a few questions on the modeling files, and would appreciate a call with you and your team at the earliest opportunity to discuss them, as well as any questions/comments EPA may have on our F' White Paper.  With Matt being out until April 5, perhaps we could target the latter part of next week?  Please let me know what days/times work and who would be participating.  I'll run those past the COETF, towards getting something booked.
                                                                    
BTW, we would appreciate it if you could provide us ASAP with the latest, updated modeling files reflecting all the revisions being made.  Based on our quick review, we have discovered that EPA has listed Ethylene Dichloride twice for every source in the Category Modeling File.  The emission rates are not identical for each of the duplicated entries, and we do not know which one is correct.  If you can provide us with the latest files, we'd be happy to perform a more thorough review in a timely manner and, potentially, identify for you other such issues/errors before you get too far in the modeling.
