Secondary Containment Rules for Canadian and U.S. Oilfield Operators
The engineering is the same on both sides of the border. The paperwork is not. Here is what each regulator actually requires — and where operators most often get it wrong.
In Canada, the Alberta Energy Regulator enforces secondary containment under Directive 055: Storage Requirements for the Upstream Petroleum Industry. Directive 055 sets a clear number: containment must hold at least 110% of the largest single container. Non-compliance brings enforcement action, shutdowns and fines under the Environmental Protection and Enhancement Act (EPEA).
In the United States, the federal SPCC rule (40 CFR 112) governs oil storage. Its wording differs in a way that matters: containment must hold "the entire capacity of the largest single container and sufficient freeboard to contain precipitation" (40 CFR 112.8(c)(2)). The rule does not state a percentage. The familiar 110% figure is an industry convention for that freeboard allowance, not a regulatory minimum — and in high-precipitation or snow-load conditions, 110% may not be enough.
State agencies layer their own requirements on top: the North Dakota Industrial Commission and ND DEQ, the Montana Board of Oil and Gas Conservation and Montana DEQ, the Wyoming Oil and Gas Conservation Commission, Utah DOGM, and the state environmental departments in Idaho, Oregon and Washington.
TCA has spent over two decades designing, fabricating and documenting containment systems for upstream operators. We size to the regulator that governs your site — not to a rule of thumb. For a fuller breakdown, see our guide to secondary containment requirements and our SPCC plan requirements FAQ.
- Volume sizing to AER Directive 055 or SPCC, whichever governs your site
- Freeboard calculated against local precipitation and snow load, not assumed
- Materials rated for hydrocarbons and temperature extremes from −40 °C to summer heat
- Seam pressure-testing on every installation
- As-built documentation for AER audits or SPCC Plan certification
- Engineered drawings and volume calculations included with every quote
110% Capacity Requirement
Secondary containment must hold a minimum of 110% of the volume of the largest single container — enough to capture a catastrophic tank failure during a storm event.
Material Compatibility
Liners and berms must be chemically compatible with stored hydrocarbons and rated for Alberta's extreme temperature range. LLDPE and HDPE are the accepted industry standards.
Documentation Protocols
Operators must maintain documented inspection routines, weld test records and corrective action logs. TCA provides full as-built documentation with every installation.
Largest Container Plus Freeboard
The SPCC rule requires containment for the entire capacity of the largest single container plus sufficient freeboard for precipitation. No fixed percentage is specified — we calculate freeboard against your site's actual rainfall and snow load.
Plan Certification
Facilities meeting the SPCC aboveground oil storage threshold need a written SPCC Plan, generally certified by a Professional Engineer. Our as-built drawings and volume calculations are prepared in the format your PE needs.
State Rules on Top of Federal
NDIC and ND DEQ, Montana BOGC and DEQ, the Wyoming OGCC, Utah DOGM and the Idaho, Oregon and Washington environmental departments each add requirements above the federal baseline. We size to whichever is strictest.

Common Questions
Everything oil and gas operators ask us before getting started — on both sides of the border.
What does AER Directive 055 require for secondary containment?
AER Directive 055 governs storage requirements for the upstream petroleum industry in Alberta. It requires secondary containment sized to hold a minimum of 110% of the largest tank's volume, using materials chemically compatible with stored fluids. Documented inspection protocols and records are also required.
How do U.S. SPCC secondary containment requirements differ from AER Directive 055?
The difference is in how the volume is defined. AER Directive 055 states a fixed 110% of the largest container. The U.S. SPCC rule at 40 CFR 112.8(c)(2) instead requires containment for the entire capacity of the largest single container plus sufficient freeboard to contain precipitation, without naming a percentage. In practice many operators default to 110%, but on a high-rainfall or heavy-snow site that may fall short. We calculate freeboard from your site's actual precipitation data rather than applying a rule of thumb.
Do you supply oilfield containment systems in the United States?
Yes. Our steel wall systems and LLDPE liners are engineered and shop-fabricated at our Taber, Alberta facility and shipped to sites across the Western United States, complete with engineered drawings, volume calculations and material certifications for your SPCC Plan. Installation arrangements vary by state — some operators use their own crews or a local contractor working from our drawings and specifications, with TCA providing technical supervision. Tell us where your site is and we'll confirm exactly how we can support the project.
Which U.S. states do you serve?
We focus on the Western States, with the strongest presence in the Williston Basin — North Dakota and eastern Montana — where the geology and operating conditions match the Saskatchewan and Alberta sites we have worked on for two decades. We also support projects in Wyoming, Utah, Idaho, Oregon and Washington. If your site is outside those states, get in touch and we'll tell you honestly whether we're the right fit.
What's the difference between LLDPE and HDPE liners for oilfield use?
LLDPE is the most common choice for oilfield secondary containment — flexible, shop-prefabricated in large panels, and performs well in cold weather. HDPE offers higher chemical resistance for sites with aggressive hydrocarbon or chemical exposure. TCA will recommend the right material based on your stored fluids.
Can TCA systems be installed without disturbing the ground?
Yes. Our steel wall secondary containment systems are engineered for zero ground disturbance. Panels sit on the existing surface with LLDPE liner and geotextile fabric — no excavation required. This makes TCA systems ideal for well pad and tank farm installations where minimizing site disruption is critical, and particularly useful on leased or reclamation-sensitive ground.
Do you provide documentation for compliance audits?
Yes — documentation is a core part of every TCA project. We provide as-built drawings, weld test records, material certifications and inspection logs. Canadian operators receive documentation structured for AER inspection. U.S. operators receive the drawings and volume calculations their Professional Engineer needs to certify an SPCC Plan.
How quickly can TCA mobilize to a remote oilfield site?
Timeline depends on project scope and current workload. After your initial quote consultation we'll provide a realistic schedule for fabrication and delivery. Contact us early in your project planning to secure your window — we serve remote locations across Western Canada and ship into the Western States.
What if our existing liner is damaged or failing?
TCA provides liner inspection, patching and full replacement services. If a seam is failing or the liner has been mechanically damaged, our certified welders can assess the damage and perform extrusion weld repairs — often faster and less expensive than a full replacement.
