Re: Portland Cement NESHAP -- CEM Cost Information


Dear Stu:

I seem to recall you had some questions  the sources of the monitoring costs.  Cost for Mercury CEMs were taken from the CAMR rule - see attached excerpt:



The rest came from a cost model tat you may access at:

Let me know if you have further questions.
