Fueling Facilities Digest, Issue No. 1: The TLS-350 Is End of Life — and CARB Has Already Acted

Fueling Facilities Digest is our monthly newsletter for fueling site operators — one issue a month, only what affects your sites. This is Issue No. 1, sent August 2026. Subscribe below to get the next one in your inbox.

This month we're focused on a change every fueling site operator needs on their radar: the Veeder-Root TLS-350 has officially reached end of life, and California regulators have already moved to reflect it.

01 — Compliance update: the TLS-350 is end of life, and CARB has already acted on it

Veeder-Root has discontinued the TLS-350 and stopped stocking OEM parts for it. A failed unit has no manufacturer path back to compliance.

In California, the TLS-350 has been removed from CARB's ISD/EVR Executive Orders, while the TLS-450PLUS is now certified on VR-201 through VR-204. Sites still running a TLS-350 are sitting on a certification gap that CARB has already written into its own framework.

Affected equipment. Any site still operating a TLS-350 console. Parts support has effectively run out, and third-party rebuilt parts void the equipment warranty and your certification.

California operators. The certification gap is active now. CARB has de-listed the TLS-350 from its ISD/EVR Executive Orders, so a functioning console can still be an out-of-compliance one.

Arizona and Nevada operators. Not exempt. The parts discontinuation is national, and federal UST rules (40 CFR Parts 280/281) still require a functioning, certifiable leak-detection system.

02 — Why upgrade to the TLS-450PLUS: more than a compliance checkbox

The TLS-450PLUS isn't just the certified replacement for a decommissioned console. It's a real upgrade: broader remote connectivity for managing fueling assets from anywhere, a security posture built for today's connected environment, and a lower total cost of ownership than servicing an obsolete platform. It's also an actively expanding platform that keeps gaining capability instead of heading toward its own end of life.

There are two ways this goes:

• Wait for a failure. An unplanned outage, on the regulator's timeline rather than yours, with no OEM parts path back.
• Upgrade proactively. You control the timeline and the budget, and the work gets scheduled around your business.

03 — Quick tip: don't let a failure make the decision for you

Check your console model. If it's a TLS-350, get ahead of your next inspection or permit renewal by scheduling your TLS-450PLUS upgrade now — on your timeline.
