Independent workflow research

How do carriers check delivery certificates?

I’m learning where the check fits into Texas fuel-delivery workflows and what happens when the public record changes between annual checks.

Early findings

What the research is showing so far

These are preliminary observations from limited industry outreach and analysis of TCEQ’s public file. They are questions to test with more operators, not statewide conclusions.

Identifiers

The facility number is the shared identifier.

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 29 file comparisons from Aug 12, 2026 through Sep 15, 2026, expiration dates changed at 1,662 facilities and owner-name entries changed at 74. At 12 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 file1,028

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

1,405 of 1,406

facility-and-tank combinations with more than one recorded status have one clear newest status after sorting by date. Earlier entries remain visible below it.

What I’m trying to learn

Four practical questions

  1. When does a delivery-certificate check happen in the workflow?
  2. Which public records, documents, or dispatch tools are used today?
  3. Do upcoming expirations or record changes create avoidable work?
  4. When is the certificate posted at the facility enough in practice?

I’m an Austin-based software and product designer. I found TCEQ’s delivery-certificate file while looking through Texas public data and started asking how carriers use it before dispatch. TankCurrent is where I’m documenting that research.
