emission units from the BART Order in Revision 1. These units are Boilers # 6 & 7. Revision 1

did not change an y emission limitations applicable to the BART eligible units. Howe ver,

remov ing the emission limitations and monitoring provisions applicable to these 2 boilers

required renumbering of several conditions. Region 10 staff was consulted on whether Revision

1 needed to be submitted as a revision to the SIP. Region 10 staff determined that this step was

unnecessary.
