US Environmental Protection Agency Office of Transportation and Air Quality NONROAD Emissions Inventory Model NRnote12.txt April 27, 2004 DRAFT NONROAD2004 Model for Nonroad Diesel Final Rule Modeling I. Overview This note contains this overview section, a section for installation of model files from the ZIP file distribution, a section for users who do not already have a version of NONROAD installed on their computer, and a section on finishing touches for all users. This release and the very limited documentation presented here are intended for users already familiar with an earlier release of the draft NONROAD model. For information about additional documentation please see the accompanying README.TXT file. This is one item in a series of notes being issued concerning the DRAFT EPA NONROAD model, which was first released in June 1998. There were updated/corrected versions of some of the model files in July and October of 1998, April 1999, June 2000, and June 2003, 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. An updated set of technical reports is being provided on the NONROAD model web page along with this version of the model. This April 2004 release contains substantial updates and enhancements to the model, including: - Benefits of nonroad diesel Tier 4 final emission standards. - Benefits of Exhaust emission standards of the November 2002 final rule on recreational vehicles, nonroad large spark ignition equipment, and diesel recreational marine engines over 50 hp (37 kw). It also updates the diesel rec marine deterioration to match what was used in this rule. Note that it does not yet include modified inventories or any benefits related to the evaporative emissions effects of that rule. - Updated base case diesel equipment populations and emission inventories based on updated historical sales data. - The Tier 3 PM and NOx emission factors for equipment applications that tend to have steady-state operation were corrected to remove extra adjustments that are only appropriate for transient operation. - Model outputs that had been labeled as "SOx-Exhaust" are now labeled as "SO2-Exhaust" to minimize confusion, since SO2 is what the numbers have always represented. - To accomodate the Tier 4 standards the horsepower ranges used by the model now split the 50-100 range into 50-75 hp and 75-100 hp. Also the prior 1500 hp point has been changed to 1200 hp, giving power ranges of 1000-1200 hp and 1200-2000 hp. In line with the above changes to the model input data files and core model (nonroad.exe), the Reporting Utility (RU) has been updated to reflect the new hp ranges and SO2 label. Other changes to the Reporting Utility include: - The conversion from Total PM as calculated by the core model to the optional PM2.5 output of the RU has been changed from 92% PM2.5 to 97% PM2.5 based on more recent test data. - The county-level reports now include the FIPS code as well as the county name. ============================================================= II. Installation from ZIP'd (compressed) Files CAUTION: BEFORE PROCEEDING WITH ANY INSTALLATION OF NEW MODEL FILES -- Due to the new horsepower ranges in the core model (nonroad.exe) and Reporting Utility (reports.mdb and nrdata.mdb), any model output data files from previous versions of the model are no longer compatible with the new Reporting Utility. If you wish to maintain access to that data, you have a couple of choices: 1) Generate any desired reports from your current reporting utility. Print them out and/or export them from the RU to Excel spreadsheet format. 2) Alternatively, you may prefer to retain your old Reporting Utility (reports.mdb) and its data file (nrdata.mdb) in a separate subdirectory or with a different name in the normal nonroad\reports\ directory. Just be careful to put these at least temporarily somewhere outside the c:\nonroad\ directory where they will not be overwritten when installing the new version of the model and reporting utility. The new Reporting Utility files in this release are: reports.mdb, nrdata.mdb, and nif.mdb. All the other files in the \nonroad\reports\ subdirectory are included to ensure completeness, especially for anyone installing the model for the first time. NIF 3.0 vs NIF 2.0 At the time of this release the NIF output ability of the default stand-alone runtime version of the Reporting Utility still uses the NIF 2.0 format. However, we are also making available a version of the Reporting Utility that that provides NIF 3.0 output. This NIF 3.0 version is not yet available as a stand-alone runtime version, which means that you must have Microsoft Access 2000 (or later) to be able to use this database. We plan to create a stand-alone runtime version of this soon, so that NIF 3.0 output can be generated by users who do not have their own MS-Access 2000 (or later) software. The NIF 3.0 output version of the Reporting Utility is provided in the folder Nonroad\Reports\RU2K\. The "2K" in this filename is a reminder that it requires MS-Access 2000 (or later) to operate. The NONROAD Graphic User Interface (GUI) is not set up to use this NIF 3.0 version of the Reporting Utility. If you have your own Access 2000 or later software and wish to use this version of the database as your default in conjuction with the GUI, you will need to edit the nr-gui.ini file accordingly. UnZIPing files: All the model files are contained in ZIP'd (compressed) files. You can uncompress and install these new files using an unZIP utility of your choice, such as WINZIP or PKUNZIP. Be sure to set the unZIP options to include the folder names when extracting the files. If using PKUNZIP from the DOS prompt, the options you should specify are: -d (restore directory structure stored in ZIP file), and -o (overwrite previously existing files) For example, the DOS command to unZIP the new NONROAD nr2004.zip file would be: pkunzip -do nr2004.zip A. Users With a Prior Installation of NONROAD If you wish to save your complete prior version of the model to maintain the ability to use it instead of the new version when desired, one possible approach is to simply rename your existing c:\nonroad directory to something else, such as c:\nr2002a depending on what prior version you have. Then create a new c:\nonroad directory into which you can install this new version. Later, anytime you want to run the old version, you would temporarily rename the directories, e.g., first rename c:\nonroad to c:\nr2004 and then rename the old c:\nr2002 to c:\nonroad. Then when ready to switch back to the new version, rename c:\nonroad to c:\nr2002 and rename c:\nr2004 to c:\nonroad. In any case, before installing this new version of NONROAD on your computer, be sure to check the warnings above about saving any desired files from previous modeling runs. You will need just the following file: NR2004.ZIP (core model, new data files, Reporting Utility, GUI) Place this ZIP file into your c:\nonroad directory and unZIP it with the unZip option to use subdirectories, allowing it to overwrite any existing versions of the files, including the entire nonroad\data\ subdirectory. When done extracting the ZIP files, you can delete the ZIP files if you wish. B. Users With No Prior Installation of NONROAD First follow the instructions in Step A above, ignoring the cautions about saving prior versions. When done extracting all the files, check that all the \data\ subdirectories exist and have files in them. E.g., nonroad\data\allocate\ should have many files ending in .ALO. Then, in order to use the Graphic User Interface (GUI) you will need to install certain Visual Basic system (DLL) files. This is done using the file: NR99A3.ZIP (graphic interface DLL files, unchanged from earlier) You will want to place the NR99A3.ZIP file into a temporary directory, such as c:\windows\temp\, unZIP it, and then run the SETUP.EXE file from there to complete the installation of the graphic user interface. After running SETUP.EXE, you can delete these files from the temporary directory. When done extracting the ZIP files, you can delete the ZIP files if you wish. Finally, please follow the instructions below in Section IV, Finishing Touches. III. INSTALLATION OF NEW FILES FROM CD Besides the necessary model installation files, the CD also contains the User Guide, which you can place anywhere you wish on your computer, or just leave it on the CD to view when needed. Note that this has not yet been updated since its release a year ago with the draft NONROAD2002a version of the model. A. Users With a Prior Installation of NONROAD on Computer CAUTION: BEFORE PROCEDING WITH ANY INSTALLATION OF NEW MODEL FILES -- Due to the new horsepower ranges in the core model and Reporting Utility (reports.mdb and nrdata.mdb), any model output data files from previous versions of the model are no longer compatible with the new Reporting Utility. If you wish to maintain access to that data, you have a couple of choices: 1) Generate any desired reports from your current reporting utility. Print them out and/or export them from the RU to Excel spreadsheet format. 2) Alternatively, you may prefer to retain your old Reporting Utility (reports.mdb) and its data file (nrdata.mdb) in a separate subdirectory or with a different name in the normal nonroad\reports\ directory. Just be careful to put these at least temporarily somewhere outside the c:\nonroad\ directory where they will not be overwritten when installing the new version of the model and reporting utility. In any case, before installing this new version of NONROAD on your computer, be sure to check the warnings above about saving any desired files from previous modeling runs. 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 you must do step III. B (3) below to remove the "Read-Only" attribute from the files. 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 with Windows Explorer. If you are using Windows 2000 or XP, you can easily do this by right-clicking on the c:\nonroad folder, select Properties, and un-check the "Read-only" box, click the Apply button and tell it to apply the changes to all subfolders and files. If you are using an earlier version of Windows, such as Windows 95, there is no option to apply the change to subfolders, so you must do the process separately for each subfolder. Open each subfolder, select all the files within each subfolder, and use the menu command - File: Properties... un-check the "Read-only" box, and click Apply. IV. Finishing Touches A. All Users: The first time you run the new Reporting Utility, you will probably 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 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 Windows Startup menu by copying the shortcut files from C:\Windows\Desktop\ into C:\Windows\StartMenu\Programs\.
