Here are some links to previous similar questions with answers - outside tanks tend to be a hundred or so higher than indoor ones due to longer fuel lines and need for a support cradle or stand, but generally a bit easier to install so sometimes it is a wash.

Costs indicated do NOT include contaminated soil cleanup and disposal - commonly $1000-2500 range for a cleanup of just a bit of surficial spillage penetrating a couple to few feet deep, if it was long-term or high volume so it got into the soil deeply then costs up from there - commonly in the multiple thousands if not into groundwater, tens of thousands if into groundwater. In some states for home tanks here is a "small volume" rapid permit/inspection process for small spills, in others you have to start the whole DEC/DEQ process as if it were a large spill, then simplifies if excavation proves the amount and spread were small.

Some fuel oil companies and fuel tank installation companies do small spillage cleanups - most or all do cleanups of just a containment basin if you have one. Larger or further-reaching spills you need an Environmental Engineering firm to assess the spill and design the cleanup and handle documentation and permits and such - which on the dozens of jobs I worked on commonly ran $10,000-50,000 total cost for long-term leaking home heating oil spills (though as high as $1/2 million for a few that got into the groundwater) - commonly started about $250K-1 million for gas station size cases.

"Average costs" are hard to quote as each case is different, but when I worked for a company in that business we ballparked the contaminated soil volume and used a VERY rough initial ballpark of $0.25-1.00/lb for excavation and disposal (high price for smaller jobs, lower for larger ones like gas stations with leaking tanks) and a minimum of $2000 - NOT including tracking down and handling any groundwater contamination.

Check your state (and in some cases county/city) AST/UST (aboveground storage tank / underground storage tank) spill regulations for cleanup permit and work and inspection requirements. State regs usually covered by an FAQ page on DEC/DEQ (Department of Environmental Conservation/Department of Environment Quality) or whatever the equivalent in your state is. Many larger and more industrial states have a separate AST/UST office.

Your fuel provider may also have a webpage summarizing the requirements. Note if leaking, under federal law the provider is not allowed to refill the tank, so this may quickly become an emergency issue for you if still in heating season in your area, or if you use oil for other appliances like water heating too.
