Steering Committee, Please remember that we will have a conference call at 2pm EDT tomorrow
(Wednesday, Nov. 8th). The dial-in number is 866-275-1366 / Passcode 51260# Agenda items are as follows: ·
Database design (Mark Young) ·
BaP ·
MDI ·
Area Sources ·
Next in-person meeting The discussion on the database design is the main discussion topic and
could take a majority of the call. Mark has posted a database design on the
development forum (http://glin.net/forum/view.php?site=glad&bn=glad_rapids&key=1162248158).
If you are able to familiarize yourself with this somewhat before the call,
that would be useful. Mark will walk us through the logic of this design as a
group and this will be an excellent opportunity to raise questions or concerns.
Chun Yi has sent some quality comments by email last week and you may want to
review her input as well. The next two topics (BaP and MDI) should
be fairly brief. For the area sources, I've attached an update to the table I sent
previously listing the area source categories included in the 2002 inventory. I've
eliminated several categories that were determined to be only associated with
CAPs. I've also filled in more information on throughput data and added a
methodology column based on the information Chun Yi sent. It's recognized that
methodologies in some states may differ from what Among the 20-25 categories I've broken out
in the table, there are about 8 that I've classified as having a
"high" rationale for estimating at a regional level. The major
considerations in labeling them in this way are the potential for saving work,
the consistency of current methodologies and the opportunity to improve
consistency in final results. We can talk about this at much greater length
tomorrow, but the way I would see this unfolding (if people are agreeable to
this) for the 2005 inventory year is as follows. ·
For the following eight categories, estimations are done
for all states/provinces at a regional level: Graphic Arts; Consumer and
Commercial Solvents; Surface Coating; Sewage Treatment; Residential Fuel
Combustion; Residential Wood Combustion; Stationary Source Fuel Combustion; and
Degreasing. ·
For all other categories, each state/province would do their
own estimations, as previously ·
Each jurisdiction would do the regional estimations for 1
of the above 8 categories. I think Residential Wood Combustion will be the most
difficult due to the sorting out of various methodology and emission factor
options and so I recommend that two states work together on that one. Many of
the others are easier and the whole region could be done with not much more
effort than doing a single state. ·
For categories where activity data is not widely available
through a national database (e.g., DOE or BLS), states will be responsible for
providing their state’s activity data to the state/province doing the
estimation. ·
Each state/province has full ability to reject, substitute
or change their own data for any of the categories. ·
Each state will receive all underlying data and calculations
(throughput, emission factors, emission, etc.) for every category done at the
regional level, so that they have full ownership of this data for future use
and reference. Again, this is just an option for the
group’s consideration to try to streamline this part of the process and
to increase the overall consistency. If there are reasons you think this will
not work, please say so. There is always the option of doing things the way we
have in the past. Talk to you tomorrow, Jon ______________________ Jon Dettling 734-971-9135 |
