Chun Yi, Let’s discuss this briefly on tomorrow’s call to see
if anyone has any input on this. Is it possible that “transportation”
includes that used by non-road engines? It seems like the EIA rather than EPA
would be the ones to know how this data was derived. Assuming that the nonroad fuel
usage is included in the first three categories you list, would there be any way
to back it out to correct the fuel use numbers? Jon ~~~~~~~~~~~~~~~~~~~ Jon Dettling 734-274-5183 dettling@glc.org From: Wu, Chun Yi
[mailto:Chun.Yi.Wu@state.mn.us] Buzz and Jon, You might saw this message previously from me.
I checked with EPA. They do not have an answer. We need to figure
it out. Otherwise there is a double counting problem. Buzz, how did
you deal with this issue? The DOCUMENTATION FOR THE FINAL 2002 NONPOINT SECTOR
(FEB 06 version) NATIONAL EMISSION INVENTORY FOR CRITERIA AND HAZARDOUS AIR
POLLUTANTS, July 2006 (ftp://ftp.epa.gov/EmisInventory/2002finalnei/documentation/nonpoint/2002nei_final_nonpoint_documentation0206version.pdf
) indicats the use of statistics from the Energy Information Administration
(EIA) for fuel consumption data for nonpoint sources for residential,
commercial/institutional, and industrial combustion. The EIA statistics separates the consumption to 5
sectors: residential, Commercial/institutional, industrial, transportation, and
electrical power generation. The nonroad sources could be in the first 3
sectors. In EPA's documentation, fuel consumption for point sources was
subtracted from total to obtain fuel consumption for nonpoint sources.
However, there is no consideration for nonroad mobile sources. I think we
should discuss this issue in the EI community. Chun Yi Wu, Ph.D., P.E. |
