              NONROAD Emissions Inventory Model

NR-NOTE7.TXT  June 2, 2000

Release of Updated Draft NONROAD Model in Support of 2007 HD
Vehicle Rule


I. Overview

The text of this memo can be found on the NONROAD CD as file
NR-NOTE7.TXT.  This is one item in a series of notes being
issued concerning the DRAFT EPA NONROAD model, which was released
in June 1998. There were updated/corrected versions of some of
the model files in July and October of 1998 and in April 1999,
which were posted on the Nonroad web site.  Various technical
reports documenting the model inputs have also been distributed
via the web site at various times since June 1998.  

This release updates the input data files to match what is being
used in the air quality modeling for the 2007 Heavy Duty Highway
Vehicle rulemaking.  Documentation of these changes can be found
in the May 31, 2000, EPA memo titled "Changes to the NONROAD
Model for the April 2000 Version Used in Support of the 2007
Heavy-Duty Diesel Engine Rule," which was submitted to the EPA
Air Docket Docket A-99-06.  This model and data files are being
made available as part of EPA's effort to allow public review of
the methods and data involved in this rulemaking.  Users should refer
to the file POSTLI12.TXT for guidance on SIP and other uses of
NONROAD.

The release contained on the June 2, 2000, CD also includes minor
updates to the Reporting Utility as described below.  The core
model executable (nonroad.exe) has not changed since Feb 23,
1999, and the Graphic User Interface (GUI) has not changed since
the last release dated January 3, 2000.  The CD includes all the
files needed to run the NONROAD model, including the core model,
the input data files, the graphic user interface (nr-gui.exe),
and the reporting utility.  

The minor changes to the Reporting Utility since the April 1999
release are: 

a) corrections to a few FIPS and county name spellings in the
   Counties table. 
b) Specialty Vehicle Carts have been changed to "lumped" in the
   Equipment Types table, meaning that 2- and 4-stroke equipment
   populations under 25 hp have been combined, in recognition
   that most of these vehicles are covered by EPA emission
   standards for small spark-ignition engines, which is expected
   to result in a shift from 2-stroke to 4-stroke engines. 
c) New airport ground support equipment SCC codes have been added
   in the Equipment Types table.  These are not currently used,
   but were added in anticipation of a more detailed future
   method of accounting for these equipment types, rather than
   counting them all as a single equipment type. 



II. INSTALLATION OF NEW FILES FROM CD

CAUTION: If wish to retain any model outputs that you already
have imported into your Reporting Utility (these are contained in the
nrdata.mdb file), you should NOT copy the new nrdata.mdb file
from the CD, since doing so would overwrite your existing
nrdata.mdb file.  Alternatively, you could save your current
nrdata.mdb file to a different directory temporarily and then
move it back into c:\nonroad\reports\ after copying files from
the CD. 

A.  Users With a Prior Installation of NONROAD on Computer

After saving any desired files as described above, you can just
copy the new files from the CD into the corresponding directories
of your computer's hard drive.  You can ignore the
nonroad\gui-inst\ directory.  Then see step B (3) below. 

B.  Users With No Prior Installation of NONROAD

 (1) Copy the entire \nonroad\ directory with all its
subdirectories onto the root directory of your c: drive,
resulting in c:\nonroad\ and all its subdirectories, such as 
c:\nonroad\data\activity\, c:\nonroad\reports\, etc. 

 (2) Go into the \gui-inst\ directory and run SETUP.EXE.  This
will install the necessary Visual Basic system files into your
windows directory to allow the Graphic User Interface (GUI) to
run properly.  

 (3) If copied from a CD, you will need to remove the "Read-Only"
attribute from most of the files.  You can do this by running the
ATTRIB.BAT file from the Nonroad directory, or you can manually
go to the DOS Prompt, change to the c:\nonroad\ directory, and
enter the command: 

attrib /s *.* -r

This sets the file attributes for all files in c:\nonroad\ and
all its subdirectories.  

A more tedious method of doing this involves using Windows
Explorer or File Manager, selecting all the files within each
subdirectory, and using the menu command - File: Properties...
and de-selecting the "Read-only" checkbox.  This is tedious
because it must be done separately for each subdirectory. 


III.  Finishing Touches

A.  All Users: The first time you run the new Reporting Utility,
you will need to Re-Attach Tables (see the Data menu). 

B.  Users Who Did Not Have a Prior Installation of NONROAD on
Computer: 

(1) You will need to create a new directory: c:\nonroad\outputs\.
This is where the core model places its output files, and where
the Reporting Utility expects to import them from.  

(2) You will want to create New Shortcuts (desktop icons).  The
first one of these should point to the "target" command line 
c:\nonroad\nr-gui.exe to be able to run the model easily.  

The second shortcut you need to create is for the Reporting
Utility.  The command line target you need to use in the shortcut
is: (all on one line)

C:\NONROAD\REPORTS\MSARN200.EXE c:\nonroad\reports\reports.mdb
 /ini c:\nonroad\reports\nonroad.ini

The third shortcut you need to create is for the Compact Utility
for the Reports.  The command line target you need to use in the
shortcut is: (all on one line)

C:\NONROAD\REPORTS\MSARN200.EXE c:\nonroad\reports\compact.mdb
 /ini c:\nonroad\reports\nonroad.ini

You can also get the proper icon to display with each of these
reporting utility shortcuts.  In the Properties for the shortcut,
click on the Change Icon... button and in the Nonroad\Reports\
folder find the "reports.ico" file for the Reporting Utility, and
for the Compact Utility choose "squash.ico."

After creating these shortcuts, you can also get them to show up
in the Startup menu by copying or moving the the shortcut files
from C:\Windows\Desktop\ into C:\Windows\Start Menu\Programs\.
