What to Know About Oil Tank Removal in Colorado
Colorado requires state certification for contractors performing underground storage tank removal, installation, and tank closure at regulated commercial and industrial facilities. The state's petroleum storage tank regulations govern UST work at gas stations, fueling depots, fleet facilities, and petroleum distribution sites. Residential heating oil tanks are explicitly exempt from both underground and aboveground storage tank regulations in Colorado. Fewer than 1% of Colorado households use heating oil, making the residential heating oil tank removal market negligible. Nearly all underground oil tank removal work in Colorado involves commercial petroleum tank removal at regulated facilities, and hiring a qualified environmental remediation contractor is critical for projects where contamination is suspected.
Colorado's commercial underground storage tank work is concentrated along the Front Range corridor from Fort Collins through Denver and Colorado Springs to Pueblo. The Denver metro area, including Aurora, Lakewood, Thornton, and Westminster, has the highest density of gas stations, fleet fueling sites, and commercial properties requiring UST compliance, tank decommissioning, and petroleum tank removal. Colorado Springs and Pueblo generate additional demand from military-adjacent fueling infrastructure and older commercial districts. Western Slope communities including Grand Junction and mountain resort towns also have fueling infrastructure requiring underground oil tank removal and ongoing maintenance as older tanks reach end of service life.
Oil tank removal cost in Colorado for commercial projects typically ranges from $5,000 to $15,000 or more depending on tank size, number of tanks, and site conditions. Petroleum tank removal at larger fueling facilities or multi-tank gas stations can exceed $20,000 when full excavation and site restoration are included. The factor that drives oil tank removal cost highest is soil contamination. When a leaking underground storage tank has released petroleum into surrounding soil or groundwater, environmental remediation can add $10,000 to $75,000 or more. Colorado's semi-arid climate means petroleum contamination can persist in soil for long periods without natural attenuation, and sites near sensitive water supplies or in areas with shallow groundwater face the most extensive cleanup requirements and highest costs. An experienced environmental remediation contractor can assess contamination extent early and help control the scope of cleanup.
Facility managers, property owners, and environmental compliance officers in Colorado must ensure full UST compliance when closing, replacing, or upgrading underground storage tanks. Tank closure must follow state environmental program requirements, including proper tank decommissioning procedures, fuel tank inspection before removal, soil contamination testing, and environmental remediation if contamination is found. Colorado operates a Petroleum Storage Tank Remediation Fund that may reimburse eligible tank owners for qualifying cleanup costs associated with petroleum releases. Whether the project involves a single gas station underground oil tank removal or the decommissioning of a multi-tank fleet fueling facility, working with a state-certified contractor ensures the job meets all applicable state and federal requirements for underground storage tank compliance and environmental protection.

Do I need a licensed contractor to remove an oil tank in Colorado?
For commercial underground storage tanks at gas stations, fueling facilities, and industrial sites, Colorado requires a state-certified contractor for oil tank removal and tank decommissioning. State certification is mandatory for UST closure work at regulated facilities. Residential heating oil tanks are explicitly exempt from Colorado's underground and aboveground storage tank regulations. However, residential heating oil is used by fewer than 1% of Colorado households, making residential heating oil tank removal extremely uncommon. Nearly all underground oil tank removal projects in the state are commercial and require state-certified contractors or a qualified environmental remediation contractor.
How much does oil tank removal cost in Colorado?
Commercial oil tank removal in Colorado typically costs between $5,000 and $15,000 or more for a standard underground storage tank at a gas station or fueling facility. Petroleum tank removal at larger multi-tank sites can exceed $20,000. Oil tank removal cost increases significantly when soil contamination is discovered. Environmental remediation for a leaking underground storage tank can add $10,000 to $75,000 or more. Colorado's semi-arid climate means petroleum contamination can persist in soil for extended periods, and sites near sensitive water supplies may face the most costly cleanup requirements.
Is soil testing required after tank removal in Colorado?
Yes. Colorado requires soil contamination testing as part of the tank closure process for regulated commercial underground storage tanks. State-certified contractors must collect soil samples from beneath and around the tank during underground oil tank removal. If petroleum contamination is found above state action levels, the site must undergo environmental remediation under state oversight until cleanup standards are met. Because Colorado's dry climate slows natural breakdown of petroleum in soil, contamination discovered during tank removal often requires active remediation rather than monitored natural attenuation. Soil test results typically come back within one to two weeks after sampling.
Does Colorado have a cleanup reimbursement program for tank owners?
Yes. Colorado operates the Petroleum Storage Tank Remediation Fund, which may reimburse eligible tank owners for qualifying environmental remediation costs associated with petroleum releases from underground storage tanks. Eligibility depends on factors including tank registration, compliance history, and whether the release was properly reported. The fund can significantly offset the cost of soil contamination cleanup for qualifying commercial sites. Having a state-certified contractor handle the oil tank removal and environmental remediation helps ensure proper documentation for any reimbursement claim. Contact the state environmental program directly to determine if your site qualifies.
How long does oil tank removal take?
A standard commercial underground storage tank removal in Colorado typically takes two to five days for the physical work, including tank pumping, excavation, tank extraction, soil sampling, and backfill. Multi-tank gas stations or fleet fueling facilities may take a full week. Fuel tank inspection results and soil contamination testing results usually come back within one to two weeks. If environmental remediation is needed due to a leaking underground storage tank, the full project timeline can extend to several months or longer depending on the extent of petroleum contamination, proximity to water supplies, and the state environmental program's review and approval process.
