Burden Statement
This collection of information is approved by OMB under the Paperwork Reduction Act, 44
U.S.C. 3501 et seq. (OMB Control No. 2060-0580). Responses to this collection of
information are mandatory (40 CFR § 51.15) and include voluntary aspects for reporting
(40 CFR § 51.15 paragraphs (a)(2)-(4) and (b)(4)). An agency may not conduct or sponsor,
and a person is not required to respond to, a collection of information unless it displays a
currently valid OMB control number. The public reporting and recordkeeping burden for
this collection of information is estimated to be 609 hours per response on average, with
lower burden on non-triennial inventory years and higher burden on triennial years. Send
comments on the Agency’s need for this information, the accuracy of the provided burden
estimates and any suggested methods for minimizing respondent burden to the Regulatory
Support Division Director, U.S. Environmental Protection Agency (2821T), 1200

Introduction
The Emissions Inventory System (EIS) receives and stores emissions inventory data and
generates emission inventories. Data are submitted to the EIS using the Consolidated
Emission Reporting Schema (CERS). State, Local, and Tribal Agencies can submit
emissions inventory data to EIS using any one of the following mechanisms:
1. Full Node. Exchange Network Node that allows machine-to-machine
transactions.
2. Node Client. Software that can be downloaded and installed on your
desktop.
3. Web Client. A web-based submission method that does not require
installing node software.
This section of the EIS User Manual focuses on submitting data using the Web Client.
The Exchange Network Services Center (ENSC) is a web-based tool
(https://enservices.epa.gov/login.aspx) designed to allow Exchange Network users the
ability to easily send, get, and download information from other partners on the
Exchange Network.
The Exchange Network Services Center utilizes three methods for the exchange of
environmental information:
•

Send Info: Submit documents or information to another system on the Exchange
Network.

•

Get Info: Retrieve information from another system on the Exchange Network. This
information is retrieved immediately through query services or requested and then
downloaded through solicit services.

•

Download: Download a document from another system on the Exchange Network
with a transaction or document ID.

The Services Center provides two options for using data services. Guide Me Step-byStep guides more novice users through the steps necessary to complete the transaction.
Express Request allows advanced users to quickly complete their transaction (see

“Exchange Network Services” for more information). The Service Center tracks a user’s
previously used services and past activity for easy use in the future.
After 20 minutes of inactivity, a user's EN Services Center session will time out. The
user will need to log back in to access the application.

Step 1: Registering for an EIS Account

The first step in the process for submitting data is to register for an EIS account. You
do this by following the instructions in the section of the EIS User’s Manual entitled
“How Do I Request Access to the EIS Gateway.” You can find the document at this
web site:
https://www.epa.gov/air-emissions-inventories/emissions-inventory-system-eisusersmanualandhow-tos .

Step 2: Creating your XML file for Submission

The next step in the submission process is to generate your EIS CERS XML file.
An XML file can be generated using your own internal system or by using the
Bridge Tool. The Bridge Tools can be downloaded from:
https://www.epa.gov/airemissionsinventories/eis-bridge-tools. You can find the
instructions for the Bridge Tool at this website: https://www.epa.gov/air-emissionsinventories/emissions-inventorysystem-eisusersmanual-and-how-tos .

Step 3: Login to the Web Client
When you are ready to submit your file, log onto the Web Client at the following
web site: Environmental Exchange Network | Services Center (enservices.epa.gov)

Specify your Central Data Exchange (CDX) username, along with your password.
All accounts should now be NAAS accounts.
For more information on requesting a NAAS account, please see the document
“How Do I Request Access to EIS Gateway? (pdf)” located here:
https://www.epa.gov/air-emissions-inventories/emissions-inventory-system-eisusers-manual-and-how-tos
For help with your account, please use the “Request Account” for “Forgot
username/password” links on the login page.

Step 4: Selecting the File You Want to Submit
Before you select a file to submit, remember these rules about the EIS CERS XML file:
•

The EIS submission file consists of an XML document, made up of the Exchange
Header (Version 2.0) and the payload, and any attached file.

•

The Payload is the actual EIS data, adhering to the structure of the CERS.

•

Any supporting documents (for the NMIM activity data or GIS files) are attached in
the form of binary attachments. These data attachments are referenced by name in
the CERS payload section of the document, but the data attachment content exists as
separate documents external to the Document structure.

•

All of these items are submitted in a single compressed ‘.zip’ file.

•

Only one category of data (i.e., FacilityInventory, Point, Nonpoint, Mobile, Events)
is allowed to be included in each .zip file; more than one category of data will cause
the entire file to be rejected by EIS.

Below is a screenshot of the Landing Page. If you click on “My Services Center,” it will
take you to “My Services.”

The screen shown above provides you with the transaction id of the submission as shown
by the top red oval above. This information will also be emailed to you. You may use the
links at the bottom of this screen to check on the status of the given submission, submit
another file, or submit a file using a different service. You are all done!
Repeat Step 4 for as many files as you need to submit
Important Process Note
Any email address you add in the “Emails To Notify” line will be the default recipient of the
notifications from CDX. This means that unless the submitters address is also entered, they
will not receive any email notifications from CDX.

Step 5: Tracking Your Submission
Once the file has been submitted, you will see a results screen that will provide a
transaction ID and a status of your submission.
The “My Activity” link lists all EN Services Center transactions completed by a user. This
page provides the necessary details of a transaction to include the service used (service
name), transaction type, date and time of the transaction, and the transaction ID.

A link is provided within the transaction ID for additional transaction details. Users can filter
their activity by:
•
•

•

Status: Filter by the status of the transactions: Completed (a transaction was
successfully completed), Failed (there was an issue with the submission, and it
failed) and Pending (the transaction has not completed processing yet).
Dataflow: Filter by the Exchange Network dataflow from which the user submitted
or obtained information.
Transaction Type: Filter by Send Info, Download or Get Info transactions.
Most Recent: Filter by transactions within the Last 30 Days, Last 60 Days, Last 90
Days or All Transactions.
Transaction Date: Filter by a date range of transactions.
Transaction ID: Filter by a specific Transaction ID.

Selecting the Clear button will remove any filters and show the full list of transactions. A
Refresh Activity link is provided at the top right-hand corner of the My Activity page that is
used to refresh the status of transactions as needed.
Users can select the “Make this my Start page” check box for this page to be the first page
that appears when logged into the EN Services Center. Users can also click “Add this page
to my Quick Links”, located in the top right corner of this page to add this page to the list of
