Please provide rationale for basing the uncontrolled formaldehyde emission factor on the MACT Standard’s limit for controlled formaldehyde emissions.

7-10     For sources using an oxidation catalyst, the EPA MACT Standard for formaldehyde of 91 ppbvd @ 15% O2 is the limit for controlled emissions.  Since the proposed facility intends to use an oxidation catalyst as a control device, please provide rationale for basing the uncontrolled formaldehyde emission factor on the MACT Standard’s limit for controlled formaldehyde emissions.
