Selling a gas station with old tanks or environmental issues

Almost every lender financing a gas station wants a Phase I. Since 2023 the federal standard for a Phase I is ASTM E1527-21, which EPA recognizes for “all appropriate inquiries” (EPA). SBA lenders follow SBA’s own environmental policy, which treats gas stations as an environmentally sensitive business that needs this extra review.

The Phase I reviews state records, the site history and your tank files, and includes a site visit. If it flags a concern, the lender may ask for a Phase II with soil or groundwater samples.

• State tank registration for every tank, with install dates, size, material and wall type
• Release detection records (monthly monitoring, line leak detector tests)
• Walkthrough inspection logs; federal rules require them at least every 30 days
• Spill prevention equipment tests, required every three years under the 2015 federal rule
• Overfill and cathodic protection tests, if they apply
• Operator training certificates
• Proof of financial responsibility: tank insurance or your state fund
• Any release reports, cleanup reports and closure or “no further action” letters

The federal requirements are on EPA’s UST operating and maintenance page. Your state may add more. Missing paperwork is often a bigger problem than the tanks themselves, and it is easy to fix before you list.

Buyers price tank age and type into their offer. Older single-wall steel tanks worry buyers and lenders more than newer double-wall systems. Some states have set hard deadlines; California, for example, required single-walled tanks to be permanently closed by the end of 2025 (California Water Boards).

You have three ways to handle it:

1. Replace before you sell and market a modern system.
2. Sell as-is with a price credit so the buyer can replace them.
3. Split the cost, often through a holdback at closing.

Which is best depends on your cash, the timeline and what your supplier will fund. Get a replacement quote either way, so the credit is based on a real number.

A closed release with a “no further action” letter is common and usually manageable. Have the letter in your file.

An open cleanup takes more work, but it can still sell. Many states run a cleanup fund that pays for eligible releases, such as Ohio’s Petroleum UST Release Compensation Board and Florida’s Petroleum Restoration Program. Whether fund coverage stays with you or can move to a buyer depends on the state’s rules, so check that early. Deals with an open release often use:

• A written plan for who finishes the cleanup and who pays
• An escrow or holdback from the sale price
• An indemnity from the seller, limited in time and amount
• Environmental insurance

An environmental attorney should write these terms.

Environmental findings usually change the terms rather than ending the deal. Common results are a lower price or a credit for tank work, a longer due diligence period while a Phase II is done, a holdback of part of the price until a cleanup milestone, or a seller indemnity for a set time. Knowing your file before an offer arrives keeps you negotiating from strength instead of reacting.

Owners who sell smoothly do three things:

1. Pull their file first. Gather the records above and look up your site on your state’s tank database, the way a buyer will.
2. Disclose early. A known issue in the first conversation builds trust. The same issue found in due diligence can end the deal.
3. Consider your own Phase I. The buyer’s lender will usually order a fresh one, but your own report tells you what is coming and lets you price it in.
