GeoTracker Submissions for UST Closures: What California Facility Owners Need to Know

Frequently Asked Questions

Do I always need GeoTracker for a UST closure in California?

Not every project is identical, and local oversight matters. Where environmental investigation, release-related documentation, or regulator-tracked closure records are involved, GeoTracker may be required or strongly expected, so owners should confirm that with the local CUPA and their environmental consultant.

Who is responsible for the GeoTracker submission on a tank closure project?

In practice, the environmental consultant often prepares and uploads the technical data. The facility owner still remains responsible for making sure the project is properly managed and the required records are submitted.

What can delay a UST closure or upgrade project?

Delays often come from missing site maps, boring logs, lab reports, or closure documentation, and from not confirming CUPA requirements early. Unexpected field conditions like staining, odors, impacted soil, or piping issues can also add sampling, reporting, and regulator review time.

What does the local CUPA usually want before and after tank closure work?

Before work starts, CUPAs may want permits or work plan approvals, notifications, lead times, sampling plans, and confirmation of who will submit data to GeoTracker. After the work, they may expect a closure package with the tank closure report, maps and figures, lab results, photos, field notes, and other supporting records.

What happens if contamination is found during tank removal?

If impacted soil or other release indicators are found, the project may shift from a simple closure into a release investigation or corrective action pathway. That can trigger added sampling, reporting, and regulator coordination under state and federal UST rules.
