Who may need to be notified after an oil spill?

AUTHORITIES AND RESPONSIBILITIES

The correct notifications depend on location, the pathway, what is threatened and whether the release is ongoing. Emergency, environmental, water, insurance and property responsibilities may overlap.

This Northern Ireland launch version uses current official Northern Ireland reporting routes. Contact details and duties can change, so check the linked official guidance when an incident occurs.

Safety and emergency services come first

Heating-oil vapours can be extremely alarming, particularly during the first day or two after a substantial release beneath or close to a building.

A strong petroleum smell does not, by itself, mean that the fire and rescue service is necessarily the most appropriate organisation to manage the contamination.

Where it is safe to do so:

• ventilate affected rooms;
• avoid smoking, naked flames and other obvious ignition sources;
• do not enter confined or poorly ventilated spaces; and
• obtain advice from an experienced environmental or spill-response specialist.

Where oil has accumulated beneath a building, specialist measures may be required to manage the source and the vapour pathway. Depending on the circumstances, these can include interception trenches, under-floor ventilation or soil-vapour extraction systems.

These measures should be designed and installed by competent specialists rather than improvised by the householder.

When the fire and rescue service is appropriate

Call the emergency services where there is an immediate threat to life, health or property, including an actual fire or a credible immediate fire or explosion hazard.

For an oil spill where the principal problem is contaminated soil, foundations or persistent vapours rather than an immediate fire emergency, an environmental spill specialist will usually be needed to address the underlying source and migration pathway.

If oil reaches drainage or water, escalate quickly

Oil entering a surface-water drain, ditch, stream, river, groundwater or another water pathway can become an off-site pollution incident very quickly.

In Northern Ireland, contact the Northern Ireland Environment Agency promptly if oil has entered, or could enter, a drain, watercourse, groundwater or another sensitive water receptor. The NIEA pollution incident hotline is 0800 80 70 60.

If a public water supply may be affected, contact NI Water using its current official emergency route. If a private water supply may be affected, contact the local council’s Environmental Health service.

Call 999 where there is an immediate threat to life, health or property, including an actual fire or a credible immediate fire or explosion hazard.

Also notify the insurer and an appropriately experienced spill-response specialist without unnecessary delay, while keeping a clear record of the information provided and advice received.

Environmental health may also have a role

Local-authority environmental health teams can be particularly useful where a spill creates potential effects on people or neighbouring property – for example:

• significant indoor odours or vapour concerns;
• contamination affecting residential accommodation;
• disputes about conditions at neighbouring premises; or
• a person being affected by a spill originating from somebody else’s property.

They do not replace the environmental regulator or environmental consultant, but they may provide an additional public-health or local-authority perspective.

This can be especially valuable where the affected householder is not the person who caused or controls the source of the spill.

Notify the insurer without unnecessary delay

The policyholder should review the notification requirements within the insurance policy and inform the insurer as soon as reasonably practicable.

Provide clear factual information about:

• when the spill was discovered;
• the suspected source;
• whether the leak is still active;
• whether emergency mitigation has been undertaken;
• whether drains, water or neighbouring land may be affected; and
• any specialist contractor already involved.

Do not delay reasonable emergency action solely because the insurer’s full claims process has not yet been completed, but keep careful records of why the action was necessary and what was done.

Warn neighbours where they may be affected

Where there is credible evidence that oil may migrate onto neighbouring land, early factual communication is sensible.

A neighbour may be able to take protective action on their own side of the boundary – for example, protecting a drain, monitoring a basement or alerting their own insurer.

The communication should remain factual:

• explain that a spill has occurred;
• explain what is currently known;
• identify the potential pathway;
• describe what is being done to control it;
• advise them to take appropriate precautions or seek specialist advice; and
• provide a contact route.

Avoid speculation about legal responsibility or making unnecessary admissions of liability.

Notify people of the risk; leave questions of liability to the insurers and legal advisers where necessary.

Other parties who may need factual notification

Depending on ownership and the circumstances, other parties may include:

• a landlord;
• managing agent;
• property management company;
• fuel supplier;
• drainage or sewerage operator;
• water company;
• landowner;
• mortgage lender where required by the relevant agreement; or
• another contractor responsible for equipment involved in the release.

Only notify those who have a legitimate reason to know, and keep the information factual.

What to report

The person receiving the report needs enough information to understand the urgency.

Where available, provide:

• the property location;
• discovery time;
• whether the spill is continuing;
• suspected source;
• fuel type if known;
• approximate quantity lost, if reasonably known;
• whether oil has entered drains;
• nearby watercourses, wells or groundwater concerns;
• neighbouring property at risk;
• current weather or rainfall;
• containment already undertaken;
• photographs where useful; and
• a reliable contact number.

If the quantity is unknown, say unknown rather than guessing.

Keep a clear record

Record every important conversation and notification.

Where possible, follow significant telephone discussions with an email or written note recording:

• date and time;
• organisation contacted;
• name of the person spoken to;
• information supplied;
• advice received;
• reference or incident number;
• actions agreed; and
• any follow-up required.

Take photographs and retain correspondence.

This helps the consultant, insurer, regulator and contractor reconstruct what happened and supports a clear chain of evidence.

Professional judgement

Tell the right people early, give them facts rather than speculation, warn anyone who may be affected, and create a written record of what you did.

Where contamination is moving towards another property or water, it is generally better to provide a precautionary warning while there is still time to act than to explain afterwards why nobody was told.

Providing factual notification that a spill has occurred does not, by itself, require the householder to make admissions about legal responsibility, cause or liability.

Get the appropriate experts involved as early as the circumstances require, and allow insurers and legal advisers to deal with any later liability questions.
