Carrier research

How do carriers check delivery certificates?

I’m inviting Texas carriers and dispatch teams to test the dashboard with their delivery locations and share how they check certificates today.

What we’ve learned so far

These findings come from TCEQ’s public file and a few industry conversations. We need to check them with more carriers.

Identifiers

The facility number linked our sample certificates to the data.

The facility number matched all 30 sampled TCEQ delivery certificates to the statewide file. Tank labels sometimes required interpretation. The source also includes the owner/operator number printed on the certificate; TankCurrent does not republish it because one owner number can cover multiple facilities.

Workflow

Checks often happen before dispatch.

An industry association contact said carriers often record the annual expiration date in an accounting system and rely on that stored date before scheduling a load.

Change awareness

The public file can change between checks.

Across 71 file comparisons from Aug 12, 2026 through Nov 4, 2026, expiration dates changed at 3,205 facilities and owner-name entries changed at 141. At 27 facilities, a later check returned the expiration to a date published earlier in the tracking period.

Matching

Carrier files do not all store the same identifiers.

An industry association contact said carrier files usually include some combination of the facility number, store location, owner or operator, and name. The mix varies across home-built systems.

Measured in the current public file1,044

facilities have at least one tank that can appear under more than one dated status in a lookup.

1,430 of 1,431

tanks at individual facilities with more than one recorded status have a single newest dated status. Earlier entries remain visible below it.

Questions for carriers

  1. When do you check a delivery certificate?
  2. Which public records, documents, or dispatch tools are used today?
  3. What do you do when a certificate expires or a record changes?
  4. How does your team use the certificate posted at the delivery location?
