A customer with an emergency only diesel generator desired to have the unit modified so that it could run for non-emergency purposes to allow the customer to use the unit to support its local utility interruptible program.
Since the unit was manufactured and in service prior to July of 2006, the unit could be upgraded to add a diesel oxidizing catalytic (DOC) filter to meet the RICE NESHAP requirements of USEPA regulation 40CFR63 Subpart ZZZZ.
The unit required permitting changes to enable it to move from emergency only to non-emergency via a synthetic minor PSD permit.
The customer opted to have a stainless steel outer enclosure placed around the DOC for aesthetic purposes.
The project took only a couple of days to install at a cost of ~$62,000.
