What is the NEI?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 emission estimates submitted by Tribal, State, and Local air pollution control agencies, estimates calculated by EPA, and emissions obtained from other sources.

EIS and the NEIEIS 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 https://eis.epa.gov/eis-system-web/welcome.html

National Emission Inventory (NEI)◦ Snapshot in time from EIS◦ Inventory version 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

How is the NEI Created?How is the NEI Created?S/L/T data has priority in EPA

selection If data are missing from the S/L/T data

file, EPA augments the data for the General Purpose Release (GPR)◦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 data

Who Has Access to the NEI?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 TEISSGeneral public does not have access to the

data until it is released to a public website

Different Types of NEI DataDifferent Types of NEI DataState 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 ITEP◦ ITEP converted to the EIS XML format

State DataState DataAdvantages

◦ Data available at any time once the agreement has been established

◦ Data in optional fields, such as Emission Unit Description, included

Disadvantages◦ Data might not be as robust as GPR

Example, if airport emissions estimated by EPA, they are not in state data files

◦ Multiple data files might need to be obtained and imported for each source category

Page 9: Importing NEI Data From EIS Into TEISS

GPR DataGPR DataAdvantages

◦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 DataNonroad and Onroad DataNational 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.

Nonroad and Onroad NCD DataNonroad and Onroad NCD DataIn the EIS Gateway report section, under

Emissions Snapshot filter, search for NCDUse the most recent “EPA Nonroad…” or

“EPA Onroad…” file for your area

ITEP can also provide the data

Instructions for Importing GPR Instructions for Importing GPR DataDataThe demonstration today is on

importing point and nonpoint GPR data that ITEP provided

If you want state data instead, set up an EIS Gateway account and work with Sally Dombrowski at EPA to establish a sharing relationship with the state agency

Initial StepsInitial StepsFiles ITEP provides, or you

download from EIS, are zippedInitial step is to extract (unzip)

the filesThen, from within your TEISS

project…

Importing Point DataImporting Point DataFor 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, there is only one point source file to import

Importing Point DataImporting Point Data

1. Check Import Point Sources box

2. Use button with folder icon to navigate to where you saved the extracted point data file

3. Check Selected Locations button

4. Select one or several counties you want to import

5. Click on Import button

Page 17: Importing NEI Data From EIS Into TEISS

WaitingWaitingImporting 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

Importing Other DataImporting Other DataNonpoint, Nonroad, Onroad, and

Event/Fire data files can be imported with the other tabs

Process is similar for these data types

Homework due in 5 days:Homework due in 5 days:Import the point and nonpoint GPR

data ITEP provided into your TEISS project (from Module 5)◦Import data for the counties surrounding

your reservation and for any other counties you feel are affecting the reservation air quality

Email the instructors a screen capture of the map when the data have been imported
