August 1981 Applicability of PSD and/or NSPS to Certain Changes Proposed for a Petroleum Storage Facility 4.20

A petroleum storage facility (4 tanks) at a refinery plans to make a product storage change. Assuming that no physical changes to the tanks happened and they were capable of handling the new product January 6, 1975. The product change is not subject to PSD review. The multi-tank storage change would be considered a single project under PSD.

If, however, other physical changes associated with the project causes a significant increase in emission, PSD would be required.
