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.

Expand each section below for more information on the necessary steps.

  • 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.

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.

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 video below to create and submit Core Data applications with your STEERS account.

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 the Central Registry Database.
  • The Tier 2 Core Data application can only be used to make affiliations, any name or address changes to a facility or customer must be done with a Core Data Form.
