Fuel Storage: Spill Prevention, Bunding and Compliance

Fuel storage is a routine requirement across construction, quarrying, aggregates, utilities, transport and manufacturing. But it is also one of the most common sources of pollution incidents. The right fuel storage controls reduce risk, protect drains and watercourses, and support compliant operations. This page answers the practical questions site teams ask most often and sets out workable, UK-focused solutions using bunding, drip trays, spill kits and drain protection.

Question: What are the main spill risks in fuel storage?

Solution: Treat fuel storage as a series of predictable failure points and control each one. Common causes include overfilling during deliveries, leaking valves and hoses, damaged IBCs and drums, poor housekeeping around pumps, and vehicle impacts. In high-activity environments like quarrying and aggregates, frequent plant refuelling, remote locations, uneven ground, and shifting traffic routes can increase the likelihood that small losses become larger spills if secondary containment and response equipment are not positioned correctly. A practical spill response strategy is to prevent releases at source, contain what you cannot prevent, then respond quickly with suitable absorbents and waste handling.

Question: What does compliant fuel storage look like on site?

Solution: Build your fuel storage around three controls: secondary containment (bunding), controlled dispensing, and emergency spill response. A robust arrangement usually includes:

• Bunded storage for tanks, IBCs and drums to capture leaks and overfills.
• Drip trays under taps, pumps, filters and coupling points to stop day-to-day drips becoming ground contamination.
• Spill kits placed at the storage point and at refuelling locations for fast first response.
• Drain covers and drain protection to prevent fuel entering surface water drains during an incident.
• Clear signage and access control to keep the area organised, inspected and secure.

Always align your controls with your site spill risk assessment and environmental management procedures. In the UK, the Environment Agency and other regulators expect effective measures to prevent pollution of land and controlled waters. Reference guidance and expectations at GOV.UK pollution prevention guidance and the Environment Agency. In Scotland, refer to SEPA.

Question: Do I need bunding for fuel tanks, IBCs and drums?

Solution: In most fuel storage scenarios, bunding is the simplest, most effective way to prevent a leak becoming a pollution incident. Bunds act as secondary containment so that escaped diesel, petrol or heating oil is held on-site for recovery rather than spreading across yard surfaces or into drainage. For many sites, bunding is a baseline control that supports duty of care and pollution prevention expectations.

Practical options include:

• Spill pallets for drums and IBCs where you want a compact footprint and easy relocation.
• Bunded drip trays for dispensing points and temporary refuelling setups.
• Portable bunds for higher-risk tasks or where plant must be refuelled away from the main yard.

Match the containment type to your container sizes, the volume stored, and how the fuel is handled. If you are unsure, treat delivery and dispensing as the highest-risk moments and design bunding around those activities.

Question: What spill kit should we keep with fuel storage?

Solution: Choose spill kits specifically suited to hydrocarbons and position them where a spill is most likely to occur. For fuel storage and refuelling, oil-only absorbents are normally preferred because they absorb fuels and oils while repelling water, which is useful outdoors and in wet conditions. Include a mix of pads, socks and pillows so you can stop the spread, protect drains, and recover pooled liquid quickly.

For effective spill response, store spill kits:

• next to the fuel tank, IBC store or drum store
• at mobile refuelling bowsers and service vehicles
• near drains in yards where fuel is moved or decanted

Use a clear restocking process so kits are always complete after use. Good practice is to assign ownership to a role, not a person, so the process survives shift changes and contract turnover.

Question: How do we protect drains if fuel is spilled?

Solution: Assume that, without intervention, spilled fuel will travel to the lowest point and enter surface water drainage. Drain protection should therefore be pre-planned. Keep drain covers and drain blockers accessible and train staff to deploy them immediately. Combine drain protection with absorbent socks to create a barrier around the flow path.

Drain protection is especially important in quarrying and aggregates where yards can be large, gradients can carry spills quickly, and rainfall can spread contamination. If you need to equip your site, see Serpro drain covers and drain protection options.

Question: What is a practical spill response plan for fuel storage?

Solution: Use a simple, repeatable sequence: stop, contain, protect drains, recover, and report. A workable on-site approach is:

1. Stop the source safely: close valves, upright containers, isolate pumps, and shut down transfer.
2. Contain using bunds, drip trays, absorbent socks and temporary bunding to stop spread.
3. Protect drains with drain covers or blockers as early as possible.
4. Recover and clean using oil-only absorbent pads and pillows, then place waste in suitable bags or bins.
5. Escalate if required: notify your environmental lead, follow your incident process, and contact regulators where the spill threatens controlled waters.

Link the plan to toolbox talks and refresher training, particularly for delivery drivers, plant operators and maintenance teams. In higher-risk sectors like quarrying and aggregates, regular drills can expose practical issues such as missing drain maps, inaccessible spill kits, or poor positioning of drip trays at refuelling points.

Question: How do we reduce fuel spills during deliveries and refuelling?

Solution: Control the transfer process and the area around it. Many fuel spills occur during coupling, uncoupling, and overfill events. Reduce risk by:

• keeping drip trays under couplings and nozzles
• using clearly marked fill points and maintaining good access for tankers
• inspecting hoses, seals and valves before each use
• keeping spill kits within immediate reach of the transfer point
• routing transfers away from drains where possible, or pre-positioning drain covers

If refuelling is carried out in the field or at temporary work faces, use portable bunding and ensure vehicles carry a compact oil-only spill kit so first response is not delayed.

Question: What fuel storage solutions should we use for drums and IBCs?

Solution: Use dedicated secondary containment matched to your container type. For drums, spill pallets and bunded platforms keep storage stable and contained. For IBCs, IBC spill pallets and bunded bases provide capacity for leaks and dispensing losses. Add drip trays beneath taps and fit-out the area with absorbents and waste containers.

Question: What inspections and housekeeping should we carry out?

Solution: Preventative checks find problems before they become spills. A simple weekly routine typically includes:

• check containers, taps, hoses and valves for staining, damp patches and odour
• confirm bunds and drip trays are empty of rainwater and debris (do not discharge contaminated liquids to drains)
• ensure spill kits are complete and accessible
• verify drain covers are available and staff know where they are stored
• keep the fuel storage area clear, well signed and protected from vehicle impact

Record findings and corrective actions. This supports environmental compliance and demonstrates good control if an incident is investigated.

Question: What do we do with used absorbents and contaminated waste?

Solution: Treat used absorbents, contaminated PPE and recovered fuel residues as controlled waste and manage them under your duty of care. Bag and label waste, store it securely, and use a licensed waste contractor. Do not wash fuel contamination into drains. Refer to UK waste duty of care information at GOV.UK waste disposal guidance.
