Importing NEI Data From EIS Into TEISS Angelique Luedeker, ITEP/TAMS Center

2 Homework Discussion Are there any questions on TEISS?

3 What is the NEI? The National Emission Inventory (NEI) is EPA’s compilation of annual estimates of air pollutants discharged from sources The compilation includes ◦ Data submitted by Tribal, State, and Local air pollution control agencies, ◦ Emission estimates calculated by EPA

4 EIS and the NEI Emission Inventory System (EIS) ◦ Data repository for air emissions data used to create NEI ◦ Contains State, Local, Tribal (S/L/T) and EPA-submitted data ◦ Annual, monthly, daily data ◦ Data available via a password-protected web site  EIS Gateway National Emission Inventory (NEI) ◦ Snapshot in time from the EIS ◦ Shared with the public ◦ Annual emissions values ◦ Reporting cycle  Every year for large point sources  Every three years for all sources, most current is 2011 inventory

5 How is the NEI Created? S/L/T-submitted data has priority over EPA-estimated data If data are missing from the S/L/T submission, EPA augments the data for the General Purpose Release (GPR) of the data ◦ Examples  If state data file includes PM10 emissions, but not PM2.5, EPA estimates PM2.5 emissions  If state data file does not contain certain nonpoint sources, EPA estimates emissions for those sources based on default activity (throughput)

6 Who Has Access to the NEI? S/L/T agency users of the EIS Gateway have access to their data and any national public releases, such as the General Purpose Release (GPR) data States may authorize Tribes READ access to their data. ◦ This allows you to download state data files for direct import into TEISS General public does not have access to the data until it is released to a public website

7 Different Types of NEI Data State Data Files – Data the state agency submitted to NEI ◦ Register for EIS Gateway account, work with Sally Dombrowski, EPA to establish an agreement with state agency to access their data ◦ Already in EIS XML format for import into TEISS GPR Data Files – General Purpose Release, Compilation of data submitted to NEI by state agencies, local agencies and EPA developed data ◦ Available from EIS, but not in EIS XML format ◦ ITEP converted to the EIS XML format

8 State Data from EIS Advantages ◦ Data available to you ongoing as the state updates their data ◦ Data in optional fields, such as Emission Unit Description, included Disadvantages ◦ Data might not be as robust (complete) as GPR  Example, airport emissions are estimated by EPA, so they are not in state data files ◦ Multiple data files might need to be obtained and imported for each source category

9 GPR Data (get thru ITEP) Advantages ◦ Likely the most sources included ◦ Does not require importing multiple files for each source category Disadvantages ◦ Does not include data in some optional fields

10 Instructions for Importing GPR Data The demonstration today is on importing GPR data that ITEP provided If you want state-submitted data only, set up an EIS Gateway account and work with Sally Dombrowski at EPA to establish a sharing relationship with the state agency

11 NEI File Import Initial Steps Extract (unzip) the files you want to import Open TEISS Open the project you started in Module 3 From within this TEISS project…

12 Import EIS XML Files Window This window opens

13 Importing Point Data Keep in mind that 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 ◦ Then import Point Emissions file  This file name starts with “Point_Emissions” For this GPR Data, there is only one point source file to import State NEI point data needs 2 files

14 Importing Point Data 1. Check Import Point Sources box 3. Check Selected Locations button 4. Select one or several counties you want to import 5. Click on Import button 2. Use button with folder icon to navigate to where you saved the unzipped point data file

15 Waiting Importing might take ten or more minutes 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

16 Success When TEISS is done importing…

17 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 Demonstration

18 Homework due in 5 days: Import the GPR data ITEP provided into your TEISS project (from Module 3) ◦ Import data for the counties surrounding your reservation and for any other counties you feel are affecting the reservation air quality the instructors a screen capture of the map when the data have been imported Read the mock Level 4 EI Clarify with your project officer what your EI should include
