-- Webased our scrubber assumptions i n the final CSAPR rule on EIA form 860 which provides information on the capability (i.e., "design" parameters under normal operating conditions) of scrubbers, as opposed to actual historical performance data. At that time, we assumed that 100% of flue ga s was treated at all scrubbers.

-- Weresponded to comments in the final rule and defended at that time that we should, as we did, use capability rather than actual performance data.

-- In the proposed revisions rule, when we tried to address the concern raised by facilities in Texas that due to stack configurations 100% of the flue gas was not being treated by the scrubber, we deviated from the approach taken in the final CSAPR when we based the proposed revisions for flue gas bypass on one historical ye ar's performance from the 2008 EIA form 923 for the units in Texas.

-- Wereceived comments from EDF, Sierra Club and NRDC pointing out the inconsistency with the approach used in the final CSAPR rule and suggesting we use scrubber capability information o n flue gas by pass that is included on EIA form 860, consistent with what we did in the final rule, for the adjustment for those units.

-- In this final revisions rule, we acknowledge the mistake in using the performance data from from the 2008 EIA form 9 23 for Texas in the revisions proposal, as opposed to scrubber capability from EIA form 860, and the correction of that mistake, which we made by taking into account scrubber capability data from EIA form 860 in this final notice.

-- Consistent with this f inal approach for the units in Texas and with the final CSAPR rule, we have also applied this approach in the direct final in responding to a comment we received in the CSAPR revisions proposal to address flue gas bypass for units in Indiana.
