Importing NEI Data From EIS Into TEISS Angelique Luedeker, ITEP

2 Options To Get 2008 Point and Nonpoint Data State Data Files – Data the state agency submitted to NEI ◦ Register for EIS Gateway account, work with Sally Dombrowski to establish an agreement with state agency to access their data GPR Data Files – General Purpose Release, Compilation of data submitted to NEI by state agencies, local agencies and EPA developed data ◦ Available from ITEP

3 State Data Advantages ◦ Data available at any time once agreement established ◦ Data can be included in optional fields, such as Emission Unit Description Disadvantages ◦ Data might not be as robust as GPR ◦ Multiple data files might need to be imported for each source category

4 GPR Data Advantages ◦ Likely the most robust data set in terms of sources included ◦ Does not require importing multiple files for each source category Disadvantages ◦ Does not include data in optional fields ◦ Does not include release point apportionment, meaning several TEISS reports pertaining to release points do not run

Nonroad and Onroad Data National Mobile Inventory Model (NMIM) County Database (NCD) emissions snapshot data available from the EIS Gateway system ◦ Emissions calculated by EPA with NMIM using state agency data. If state agency did not supply data, EPA calculated emissions with NMIM using EPA default activity data

6 Nonroad and Onroad NCD Data Under Emissions Snapshot filter, search for NCD Use most recent “EPA Nonroad…” or “EPA Onroad…” file for your area

7 Initial Steps Files you download from EIS are zipped Initial step is to extract (unzip) the files Then, from within your TEISS project…

9 Importing Point Data For State Data, you must import data for point sources from two different files ◦ Facility Inventory file must be imported first  This file has “Inventory_Snapshot” in its name ◦ You can then import Point Emissions file  This file name starts with “Point_Emissions” For GPR Data, only one point source file to import

10 Importing State Data Facility Inventory File 1. Check Import Point Sources box 2. Use button with folder icon to navigate to where you saved the “…Inventory_Snapshot…” file 3. Check Selected Locations button 4. Select one or several counties you want to import 5. Click on Import button

11 Waiting Importing might take awhile depending on ◦ File size ◦ How many counties you import We recommend importing data for not more than three counties at a time, unless you have time to let your computer work For this class, make sure you do not select All Locations under Import Options ◦ It could take hours to load data for all counties in a state, depending on file size

12 Success When TEISS is done importing…

13 Importing State Data Point Emissions File Repeat process to import Point Emissions file However, in Step 2, navigate to where you saved “Point_Emissions…” file Make sure you import emissions for same counties for which you imported facility inventory data

14 Importing Other Data Nonpoint, Nonroad, Onroad, and Event/Fire data files can be imported with the other tabs Process is similar for these data types; however, there is only one file you need to import for each of these data types

15 Airport Emissions Data Emissions data for airports might not be in State Data you imported If you notice this in TEISS project, import those point emissions from a separate file Get this file from EIS Gateway system After extracting file, import file into TEISS as you do with Point Emissions file

16 Getting Airport Data From EIS In Reports section, select Request Reports, scroll down to Emissions Snapshot, click By Responsible Agency For Emissions Snapshot criteria, find data set EPAAirports1109, select it

17 Getting Airport Data From EIS (cont.) Click on Search button In search results, find Point data category, click on “Download” link Find data set for your area from list, download
