Tank Site Remediation

We start with tank history, system layout, soil and groundwater data, and consultant remedial criteria. We also confirm access, utilities, operating restrictions, consultant responsibilities, notices, and the intended endpoint. Resolving these items before mobilization lets the field team establish controls, receiving routes, hold points, and contingency space instead of making compliance decisions beside an open excavation.

The main drivers are tank bed, fill, vent, lines, joints, dispensers, pumps, and water table. Weather, laboratory turnaround, inspection availability, and working hours can also control production. We build the sequence around the slowest approval or physical constraint and identify parallel tasks that continue without covering work, mixing materials, or compromising a required hold point.

The governing requirements depend on the material, property, equipment, and approval. The work can involve staged removal with consultant samples and written release before backfill. We confirm the current project specific criteria with the engineer, Qualified Person, owner, municipality, or TSSA as applicable. A general industry practice never replaces the written requirement that governs the actual site.

Our field record includes free product recovery, settling, filtration, treatment, or authorized off site handling. Entries are tied to dates and work areas so quantities and events can be reconstructed. We reconcile documents during the job, not only at closeout, which gives the owner and consultant time to correct a missing ticket, unclear location, or inconsistent quantity before demobilization.

We use separate labelled cells, approved destinations, load records, and weather controls. Work pauses until the condition is safe, isolated, and assigned a documented response. The supervisor records what changed, where it occurred, who provided direction, and how material or equipment was controlled, preventing an unexpected discovery from contaminating accepted work or disappearing from the record.

Yes, where the design permits it. We plan shoring, utilities, property limits, risk decisions, and alternative treatment methods. The operating boundary, shutdown windows, truck route, emergency access, controls, and daily handback condition are agreed before work starts. Production is staged so facility staff and construction crews do not share uncontrolled access to the work zone.

Closeout should include approved fill, controlled lifts, density tests, survey, and pavement or slab repair. Depending on the project, it can also include photographs, surveys, receiving records, inspection releases, operating logs, test results, redline drawings, and a list of remaining assets. The package supports the owner's consultant and operations team, but professional certifications remain with the appropriately qualified person.
