Step 3: Tier II Core Data

This is the third of six reporting steps. Information on using STEERS to access the Tier II Core Data application.

Step 1  Step 2 Step 3  Step 4  Step 5 Step 6

Beginning January, 2019, all Tier II reports will be submitted using the Tier II Online Reporting System:

 If you already have a CN and RN number(s) through another TCEQ program, you are required to use those numbers. You already have a TXT2 number if you have ever filed a Tier II report in Texas. Use the same TXT2 number for all facilities with the same owner or operator. Each TXT2 number should have only one CN associated with it, and vice versa.

Tier II Identifying Numbers

  • TXT2 Number: 
    A program identification number unique to the Tier II Chemical Reporting Program. TXT2 numbers are 5 or 6 digit numbers that are assigned to owners or operators of facilities.
  • Customer Number (CN):
    Each customer (individual or organization) is issued a unique 11-digit identification number called a CN (e.g. CN123456789). Each customer should have only one CN based upon their name and Texas Secretary of StateExit the TCEQ or Texas Comptroller of Public AccountsExit the TCEQ information as applicable.
  • Regulated Entity Number (RN): 
    Each site location is issued a unique 11-digit identification number called a RN (e.g. RN123456789). Each regulated entity should have only one RN number per address or physical location.

Note: Each CN can only be affiliated with a single TXT2 number, and vice-versa.

Verify if you already have number(s)

CNs and RNs associated only with the Tier II Program are not visible in Central Registry. Only CNs and RNs associated with other programs are visible in Central Registry. Contact us for more information.

Obtain new CN, RN and TXT2 numbers

If you do not have a CN, RN, or TXT2 number, or need to claim ownership of a recently purchased facility, you will need to use STEERS to create them. For information of creating a STEERS account see our Setting Up STEERS page.

Follow along with the screenshots below to make Core Data applications with your STEERS account. Use the arrows (    )  to navigate to the next step.

Once you have completed a Tier II Core Data Application you will be sent an email with a PDF Notice of Approval that will include your TXT2 Number, CN, and RN associated to or created for your application. (See page 40 in the Tier II User Guide)

  • Review your information in Central Registry Database.
  • All changes to your CN and RN information related to the Tier II program will be handled through STEERS in the Tier II Core Data e-Permits Program Area. Paper copy Core Data Forms will no longer be accepted.
  • Changes that will affect other parts of the Agency will require you to reach out to the Central Registry team.
