	Attached find 2010 data for all the combined cycle units that came
on-line in the last five years (i.e., 2006-2010).  Of the 74 units, 63
are reporting annual CO2 emission rates of less than 1000 lb/ MWh.  Of
the remaining 11 units, we believe that many are not reporting their
full electric output.  Under current reporting rules, if there is no
supplemental firing (e.g. additional fuel burned) in the heat recovery
steam generator (HRSG), it not necessary to report the generation
associated with the HRSG.  Since this represents a significant portion
of generation, most, if not all of the units would meet a 1000 lb/MWh
standard once they began reporting this information.  We are doing
additional work to confirm which units are only reporting data from the
combustion turbine.   We believe that the data from the 63 units already
shows that units covering a range of sizes, types of operation and
location (e.g., ambient temperature and elevation) can meet a standard
of 1000 lb/MWh.
