What oil tank removal actually costs in Eugene, OR in 2026

The honest 2026 ranges for Eugene

Here are the 2026 ranges. These reflect quotes from DEQ-licensed providers inside the 97401 to 97408 corridor; rates further out in Lane County run different.

• 01.Underground tank, clean decommissioning, full removal: typically $1,500 to $3,500. Most common Eugene scenario. Includes permit, locate, excavation, pump/clean, cut/remove, 2-3 soil samples, backfill, ORELAP lab fees, Decommissioning Report.
• 02.Underground tank, clean abandonment in place: typically $1,200 to $2,800. Tank stays in the ground after pump/clean/fill. Used when removal would damage structures.
• 03.Aboveground tank, exterior: typically $400 to $1,600. No excavation, but DEQ still requires residual product manifest and steel disposal documentation.
• 04.Basement or crawl-space tank: typically $1,000 to $2,000. Pump, clean, cut in place, remove through stairwells or doorways.
• 05.Localized release cleanup adder: typically $3,500 to $15,000. Additional excavation, off-site soil disposal, confirmation samples, supplemental Decommissioning Report.
• 06.Full DEQ Cleanup Rule case: typically $15,000 to $75,000 and up. Site characterization, possible monitoring wells, Cleanup Report, DEQ No Further Action letter. This is the risk-based route for sites that cannot meet the generic remedy conditions.

What drives Eugene-area pricing up or down

Six things move a Eugene quote up or down. Working out which ones apply to your property tells you whether to expect the low or high end of the range.

• 01.Tank size and depth. A 250-gallon tank buried 3 feet deep on a flat side yard is the easy case. A 1,000-gallon tank under 5 feet of cover, with a mature tree close to the pit, runs noticeably more. Most Eugene tanks are 250 to 500 gallons buried 2 to 4 feet deep.
• 02.Equipment access. Crews need to bring a mini-excavator, vacuum truck, and dump trailer to within working distance of the tank. South Hills properties on steep grades sometimes require switching to manual digging and add $400 to $800. Whiteaker properties with narrow alley-only access also add cost.
• 03.Surface restoration. Sod backfill is included in most base quotes. Restoring a poured concrete driveway, paver patio, or established landscape (mature shrubs, irrigation lines, raised beds in the Friendly Area) runs $400 to $1,500 on top.
• 04.Permit jurisdiction. Three different counters serve this metro. City of Eugene inside city limits, Springfield running its own, and Lane County Land Management for unincorporated parcels. Each sets its own fee and turnaround, so the number that applies is the one the issuing office quotes for your address.
• 05.Lab and disposal fees. ORELAP-accredited labs charge $80 to $140 per sample for TPH-Dx plus BTEX. Tank steel goes to a scrap recycler, and residual fuel and sludge are charged by volume for off-site recycling. All of it should be in the base quote, not added later.
• 06.Season and crew availability. Peak demand in Eugene is March through May (escrow season) and August through October (pre-winter conversion push). Off-season scheduling (mid-November through mid-February) can come in lower, weather permitting.

Underground tank cost breakdown, line by line

A typical $2,400 Eugene-area underground tank decommissioning breaks down roughly as follows. Use this to read a quote: any missing line items mean the price will climb at invoice.

• 01.Permit (City of Eugene, Springfield, or Lane County). Set by whichever office serves the parcel, and itemized in an honest quote rather than folded into a single total.
• 02.Utility locate (Call 811): $0. Free state program but requires 48-hour notice.
• 03.Excavation and tank exposure: $500 to $800. Mini-excavator on site for half a day. Biggest single line item.
• 04.Pump and clean: $300 to $450. Vacuum truck for residual fuel and sludge. Varies with how much fuel remains.
• 05.Cut and remove tank steel: $250 to $400. Non-sparking saw, lift to dump trailer, transport to certified recycler.
• 06.Soil sampling: $300 to $500. 2-3 samples per DEQ protocol, ORELAP lab fees, chain of custody, turnaround.
• 07.Backfill and compaction: $300 to $450. Clean fill placed in lifts, compacted to grade, surface restoration.
• 08.Decommissioning Report: $200 to $350. Drafting, photo documentation, DEQ filing at the East 7th Avenue office.

That totals roughly $2,000 to $3,250 for a clean decommissioning, matching the published range. If a quote comes in below $1,800 for a buried tank, ask which line items are missing. The most commonly omitted: lab fees (added as "pass-through" on the invoice), Decommissioning Report drafting fee, and surface restoration.

Soil sampling and lab fees: where surprises hide

Soil sampling is the line item cheaper quotes most commonly leave out. The samples are required by DEQ; the labs that analyze them must be ORELAP-accredited; and the fees are real. A typical Eugene decommissioning runs $300 to $500 in lab work for the sampling alone.

• 01.Sample collection labor: $50 to $100 per sample. Crew pulls, fills lab bottles, labels, completes chain of custody.
• 02.TPH-Dx analysis: $60 to $90 per sample. Total petroleum hydrocarbons in the diesel range. Primary screening for heating oil.
• 03.BTEX analysis: $40 to $70 per sample. Benzene, toluene, ethylbenzene, xylenes. Benzene is the regulator-priority constituent.
• 04.PAH analysis if requested: $80 to $150 per sample. Polycyclic aromatic hydrocarbons. Used for older or weathered contamination.
• 05.Lab turnaround: 7 to 14 business days standard, 2 to 4 days rush. Rush adds 50 to 100 percent to lab fees.
• 06.Number of samples: 2 to 4 typical. DEQ guidance is one beneath each tank end plus one stockpile sample when soil is relocated.

When soil samples come back hot: Eugene contamination tiers

A minority of Eugene-area underground tank decommissionings return at least one soil sample above DEQ residential cleanup levels. Here is what each tier typically costs in Eugene in 2026:

• 01.Tier 1: Localized exceedance. Typically $3,500 to $12,000. One or two samples over the limit. Crew returns, excavates the affected area, samples the new boundary, repeats until below screening levels. Soil goes to a permitted facility, typically Short Mountain Landfill in Lane County or Coffin Butte Landfill in Benton County, both of which accept petroleum-contaminated soil. Supplemental Decommissioning Report. Most common contamination scenario.
• 02.Tier 2: Multi-zone or moderate depth. Typically $12,000 to $28,000. Contamination extends beyond the immediate tank pit or below 4 to 6 feet. Larger excavation footprint, more disposal volume, additional confirmation rounds, possibly site characterization borings.
• 03.Tier 3: Full Cleanup Rule with groundwater. Typically $28,000 to $75,000 and up. Contamination reached groundwater or migrated significantly. Site characterization, monitoring well installation, Cleanup Report, DEQ No Further Action determination. Groundwater impact disqualifies the generic remedy outright, so these files run the risk-based route.

Budgeting for a cleanup nobody else is going to fund

Before you build a number, settle who is on the hook, because three plausible sources of help turn out not to be. There is no Oregon program: the state runs no reimbursement fund, no insurance pool, and no grant for residential heating oil cleanup. Insurance is unlikely: most homeowner policies exclude fuel releases from a tank the insured owns. And the previous owner is usually out of reach. DEQ's position is that the current owner of the property is responsible for any necessary cleanup even if the leak happened before he or she bought the property.

• 01.Get the insurance answer in writing before you assume it. Policy wording varies by carrier, so the exclusion is the likely outcome rather than a certainty. Ask your carrier for a written coverage position on a release from an owned heating oil tank at your address, and file the reply with the tank paperwork. It costs nothing and it settles the question at the point where a verbal maybe would otherwise sit in your budget as a line item.
• 02.Buying a house does not reset the clock. The obligation attaches to current ownership, not to whoever put the oil in the ground. That is why a decommissioning quote and a cleanup contingency belong in the purchase math on any Eugene property with a pre-1985 build date and an unresolved tank question.
• 03.Seller disclosure turns on actual knowledge. Oregon's disclosure obligation asks what the seller knows, which means "Unknown" is a complete and lawful answer. Sellers do not need to commission an investigation to fill in the form, and buyers should read an "Unknown" as an open question rather than a denial.
• 04.Concealment is a lawyer's question, not a budget line. If you believe a seller knowingly hid a tank or a release, take it to a Eugene real-estate attorney as a civil matter. Do not build the cleanup budget on the assumption you will recover it.
• 05.The number itself hinges on the closure route. A site that meets DEQ's generic remedy conditions skips site-specific risk characterization; one that does not runs a risk-based cleanup instead. In Eugene the condition that most often decides it is groundwater, so a property on the shallow-water ground toward the river should be budgeted with the more expensive route in view.

How to compare Eugene-area quotes

Most Eugene homeowners line up two or three bids before they commit. How to read what comes back:

• 01.DEQ license number on the proposal. Verify against the DEQ Service Provider list. An unlicensed bid is cheaper because it skips the one thing that matters: it never produces a Decommissioning Report.
• 02."Fixed price" not "starting from." Open-ended quotes with "additional fees may apply" almost always end higher than the spread.
• 03.Written soil-sample plan. Number of samples, locations, lab name (ORELAP only), analyte panel, turnaround.
• 04.Permits in or extra? City of Eugene / Springfield / Lane County permits should be in base, not extra.
• 05.Contamination contingency clearly stated. Base price (clean decommissioning) + tier-1 rate (per cubic yard of contaminated soil) + tier-2 escalation rate.
• 06.Decommissioning Report drafting and DEQ filing included. Should be in base, not a $200-$300 add-on.
• 07.Surface restoration. Sod or gravel back to grade should be included. Concrete, pavers, landscape restoration is reasonable to break out.
