Law and responsibilities for spills and tanks in Canada

Fuel spills and storage tanks sit where several areas of law meet. Workplace safety law protects the workers who respond to a spill. Fire codes govern how tanks and dispensers are built and run. Environmental law decides what must be reported, who pays for cleanup and how tanks must be monitored for leaks. Hazardous products rules cover labels, safety data sheets and training for fuel and the cleanup products used on it. And waste rules decide how contaminated absorbents must be stored, transported and disposed of. A station worker does not need to be a lawyer, but knowing which rules exist, who enforces them and what they expect of the people on shift makes it much easier to do the right thing quickly.

This lesson maps those rules at a high level. It does not quote clause numbers, because rules change and the details vary by province, state and municipality. When a detail matters, the station's written spill procedure, the company's environmental coordinator and the regulator's own guidance are the places to check.

Who makes the rules

In Canada, most rules that affect a fuel station are provincial. For Northfield in Alberta, they are:

• Workplace safety: the Alberta Occupational Health and Safety Act, Regulation and Code, which require the employer to assess hazards, provide training, equipment and procedures for emergencies such as spills, and protect workers during cleanup.
• Fire safety and tanks: the Alberta Fire Code, based on the National Fire Code of Canada, which sets requirements for storage tank systems, leak detection, inventory records, spill containment and dispensing. Municipal fire departments inspect.
• Environmental protection: the Environmental Protection and Enhancement Act and its Release Reporting Regulation, which require releases that cause or may cause an adverse effect to be reported, and require the person responsible to take action. Alberta Environment and Protected Areas runs the program.
• Tank registration: in Alberta, underground and many aboveground petroleum tanks at retail sites must be registered with the Petroleum Tank Management Association of Alberta, which keeps the registry and oversees tank installation, upgrades and removal under the fire code.
• Hazardous products: WHMIS, which requires labels, safety data sheets and worker education for gasoline, diesel and hazardous cleanup products.
• Waste: Alberta's waste control rules, which treat fuel-soaked absorbents and contaminated soil as hazardous or special waste that must go to a licensed facility.

Federal rules in the background

Federal law applies in some situations. Environment and Climate Change Canada's Storage Tank Systems for Petroleum Products and Allied Petroleum Products Regulations cover tanks on federal land and federal facilities, such as stations on First Nations reserve land, national parks, airports or federal properties, and require registration, leak detection and release reporting there. The federal Fisheries Act prohibits depositing a harmful substance, such as fuel, into water frequented by fish, and a spill that reaches a creek can bring a federal investigation as well as a provincial one. Transport of dangerous goods, including the fuel truck and any waste shipped from the station, falls under the Transportation of Dangerous Goods rules.

Who is responsible for what

The law places most responsibility on the owner and operator of the station and its tanks, but everyone on the site has a part to play.

Unlike the United States, Canada does not have a national operator training scheme for tank systems. In Alberta, the fire code and the employer's duties under OHS law together mean that workers must be trained in the station's procedures for alarms, spills and emergencies, and records of that training should be kept. Northfield trains every attendant in the spill procedure during orientation and refreshes it every year with a drill.

The duty to act

Environmental law does not just require reporting; it requires action. The person responsible for a release must take reasonable steps to stop it, contain it and clean it up, and must not make it worse. In practice, that means the first actions of the worker on shift, stopping the source and protecting drains, are part of meeting the company's legal duties. A spill that is reported promptly and handled well is treated very differently from one that is ignored, hidden or washed down a drain.

This is also why the station procedure and records matter. When a regulator asks what happened, the company needs to show when the spill was found, what was done, how much was released and recovered, where the waste went and who was told. Lesson 9 covers the report itself, and Lesson 5 covers the waste paperwork.

Workers' rights and protections

Workers have rights during a spill, too. They have the right to know about the hazards of fuel and cleanup products, through labels, safety data sheets and training. They have the right to the PPE the job needs, provided by the employer. And they have the right to refuse work they believe is dangerous, such as being asked to clean up a large spill without training, equipment or ventilation, or to work beside a spill that has not been made safe. A worker who refuses unsafe work must follow the procedure for doing so, but must not be punished for raising a genuine concern.

In Alberta, the OHS Act sets out the process for refusing dangerous work and protects workers who use it; HSE-102 covers it in detail.

For supervisors: the binder at the counter

Keep a spill binder at the counter, next to the tank gauge console. It should contain the station's spill procedure on one page, the phone numbers for emergency services, the manager, the environmental coordinator, the contractor and the regulator's spill line, a site plan with drains and spill kits marked, blank spill report forms, and the safety data sheets for the fuels and cleanup products. Check it every quarter: phone numbers and contractors change. A worker on the late shift should be able to handle the first hour of a spill with that binder and nothing else.

Records the law expects

Most of what an inspector checks at a fuel station is paperwork. The records prove that the tanks are being watched, that alarms are answered and that spills are handled. If a record is missing, the inspector has to assume the job was not done. Keeping records is therefore part of the job, not an extra.

When the inspector visits

A fire department inspector, a tank registry inspector or an Alberta Environment and Protected Areas officer may visit the station, either on a routine inspection or after a spill report. The worker on shift should be polite, ask for identification, and call the manager right away. The inspector may ask to see the tank gauge, the spill kits, the drains and the records. Workers should answer honestly about what they know and did, and should not guess about things they do not know; saying "I don't know, but the manager can tell you" is a perfectly good answer.

Inspectors see the same problems again and again: spill buckets full of water and fuel, alarms silenced and not followed up, inventory records that were never reconciled, empty spill kits, and staff who cannot say where the storm drain goes. Each of these is cheap to fix before the visit and expensive to explain after a spill. Lesson 7 covers the tank equipment and Lesson 8 the inventory records in detail.

After the visit, the manager should read the inspection report carefully, fix every item it lists by the date it gives, and keep a copy with proof of the fix, such as a contractor's invoice or a photo of the new spill kit. An item that appears on two inspections in a row is a sign that the station's own checks are not working, and that is the point to change the routine rather than just fix the item again.
