>Subject: emissions from heat treatment of steel
>We heat-treat steel parts by quenching the red-hot parts in a tank of oil.
>This creates a lot of smoke, which we collect with a fiberglass filter.  The
>state environmental department is reviewing our application for a Synthetic
>Minor (Title V) permit.  We have been asked to provide emission data from
>this operation, both before and after the filter.
>I haven't had any luck finding anything we can use in AP-42.  Does anyone
>have any suggestions of how we can estimate the emissions from this process,
>short of stack testing?
>Thanks for any help.

>Again, you may have thought of this already.  Good Luck!
