Installation and site work completed in accordance with Ontario requirements.
Fuel system decommissioning permanently takes tanks, dispensers, pumps, lines, vents, controls, and related equipment out of service through verified isolation, product recovery, cleaning, removal or approved closure, and documentation. Harrowgate completes the coordinated field work across Toronto and the GTA under the applicable TSSA fuel requirements and site environmental plan.
Our fuel system decommissioning sequence starts with verified site information, controlled work zones, and written acceptance points, then moves through field execution, consultant inspection, records, and restoration. We assign each material, asset, sample area, and load a defined status so crews know what can move, what must remain exposed, and who releases the next step.
We verify drawings against field tracing, label the system, schedule the shutdown, and establish lockout and product transfer. Residual fuel is recovered from tanks, low points, filters, and lines. Equipment is cleaned as required, atmosphere is controlled, and each connection is physically isolated.
Tanks and dispensers are removed using the planned excavation or lifting method. Underground piping is exposed at critical points, drained, removed where practical, or closed only by an approved method. The consultant observes potential release locations. We remove controls, seal penetrations, restore surfaces, and update the asset record.
Harrowgate coordinates shutdown, product transfer, excavation, lifting, environmental response, civil reinstatement, and records with one field schedule. Our crews control the work area and keep exposed equipment protected from traffic and weather. Owners receive practical daily reporting on recovered product, removed components, disposal documentation, discovered conditions, inspection points, and restored surfaces.
Materials and acceptance criteria for fuel system decommissioning come from the current Ontario requirements, approved drawings, consultant documents, receiving facilities, and owner standards that apply to the actual site. We check those criteria before procurement or hauling, record field changes, and preserve the evidence required for inspection, environmental review, and future construction.
Decommissioning follows the TSSA framework and code currently adopted for the fuel system, including the Liquid Fuels Handling Code or CSA B139 series where applicable. The system owner and qualified fuel contractor confirm notification, inspection, removal, and documentation requirements. Product, sludge, filters, wash water, contaminated absorbent, piping, concrete, and soil are classified separately. Isolation details show caps, blinds, disconnected feeds, and termination points. Where a line remains, its status and exact surveyed route must be recorded to prevent future misidentification.
Ontario fuel equipment is governed by the Technical Standards and Safety Authority framework and the code adopted for the fuel involved. Current requirements can include the Liquid Fuels Handling Code, its Ontario adoption document, or the CSA B139 series for oil burning equipment. Tank construction, supports, venting, fill, overfill protection, leak detection, corrosion protection, clearances, and contractor qualifications are confirmed against the approved design and current adopted edition.
Fuel System Decommissioning fails when field production gets ahead of characterization, isolation, inspection, or documentation. Harrowgate prevents that gap with staged work, clearly marked hold points, segregated materials, daily records, and immediate escalation of changed conditions. The goal is to protect people and operations while avoiding rejected loads, concealed deficiencies, repeat excavation, and schedule loss.
The largest risk is an unrecognized connection that leaves fuel, pressure, or a pathway into the supposedly closed system. Cross connected tanks, buried tees, siphon effects, and remote fills can defeat a simple valve closure. Abandoned lines can later be mistaken for live services. We combine records review, tracing, exploratory exposure, draining from low points, physical disconnection, and clear tags. Work does not proceed to cutting or excavation until the isolation boundary and product recovery are verified.
We review the next two weeks of work against approvals, sampling, deliveries, shutdowns, and weather. Daily pre work discussions identify the exact limits and status of each area. Photographs and measurements are taken before concealment, and unresolved items stay visible on the field log until the responsible reviewer provides direction or acceptance.

We start with every tank, line, pump, dispenser, vent, control, fill, and remaining endpoint. 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 records review, physical tracing, labels, exploratory exposure, and controlled shutdown checks. 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 recovery from tanks and low points with separate approved receiving and volume records. 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 removal where required or practical, otherwise only an approved documented closure method. 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 sampling around tanks, dispensers, joints, low points, and visible release locations. 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 updated asset records, surveyed remaining lines, caps, tags, photos, and receiving documents. 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 temporary approved fuel arranged before switchover for critical equipment. 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.
