MEMORANDUM

TO: EPA Docket #EPA-HQ-OAR-2009-0211

FROM: Robert Anderson, Environmental Protection Specialist,
EPA/OAR/OTAQ/CISD

RE: Data from pre-Tier 2 DOE Catalyst Durability Program (V4/CRC E-87-2)

Attached is an Excel spreadsheet that contains data from the DOE
Catalyst Durability Test Program also referred to as the DOE V4 program
or the CRC E-87-2 program.  These data are results for the pre-Tier 2
vehicle portion of the test program.

The enclosed spreadsheet contains all data for non-Tier 2 vehicles
submitted to EPA from DOE as of January 5, 2010.  These data include all
DOE pre-Tier 2 test data that were a part of the preliminary data set
EPA submitted to the docket on November 17, 2010 (see Docket ID
EPA-HQ-OAR-2009-0211-14045) as well as additional data collected since
that time.  As was the case in the original waiver decision (see Docket
ID EPA-HQ-OAR-0211-14019), some (i.e. for the 2000 Honda Accord aged on
E0) non-methane organic gases values may need to be recalculated and
will be posted shortly.  

It should be noted that these data could be subject to change based on
ongoing QA/QC.
