What Is a Phase 1 Environmental Site Assessment?
A Phase 1 Environmental Site Assessment, written as Phase I ESA in most reports, is a records review and site inspection that looks for signs a property has been contaminated by hazardous substances or petroleum. The consultant follows ASTM Standard E1527-21. Nobody drills or samples anything during a Phase 1.
The work covers historical aerial photos, fire insurance maps, city directories, regulatory database searches, a walk of the property, and interviews with the owner, the occupants, and anyone else who knows the site's history. The report ends with a finding of whether any Recognized Environmental Conditions exist.
Lenders ask for a Phase 1 before they fund a commercial purchase or refinance. SBA 7(a) and 504 loans require environmental due diligence on most real estate collateral. Buyers order one on their own because a Phase 1 completed before closing is what qualifies them for the innocent landowner and bona fide prospective purchaser defenses under CERCLA.
What a Phase 1 ESA Reviews in Oregon
The state records for a Oregon Phase 1 come from Oregon Department of Environmental Quality, searched alongside the federal databases every Phase 1 covers.
The Department of Environmental Quality keeps its cleanup records in the Environmental Cleanup Site Information database and its tank records in separate leaking tank and registration lists, and all of it is reachable through the agency's Facility Profiler map. Oregon has two programs that show up in a Phase 1 more than in other states. The Heating Oil Tank program tracks decommissioned residential tanks, and the Portland Harbor Superfund site puts any property along the lower Willamette River into a cost allocation process that buyers need to understand before closing.
The Oregon lists a consultant checks for a property in Oregon:
- Environmental Cleanup Site Information database. Every site DEQ has investigated or listed for cleanup, with documents and status.
- Leaking underground storage tank database. Reported petroleum releases and their cleanup status.
- Underground storage tank registrations. Regulated tanks at commercial facilities.
- Heating Oil Tank program records. Decommissioning and cleanup certifications for residential heating oil tanks, which are common in Portland.
- Portland Harbor Superfund records. The site boundary, the list of potentially responsible parties, and the allocation process for properties on the lower Willamette.
- Voluntary Cleanup Program and Prospective Purchaser Agreement records. Enrolled sites, No Further Action determinations, and agreements that release a buyer from liability.
Common Sources of Contamination on Oregon Properties
Timber built Oregon, and sawmills, plywood plants, and wood treating operations sat on rivers across the state, leaving creosote, pentachlorophenol, and dioxins in soil and sediment. Portland's waterfront had shipbuilding, tank farms, and metal recycling. The Willamette Valley's orchards and hop yards used lead arsenate and other pesticides. Heating oil tanks are buried at homes and small commercial buildings throughout Portland and the older neighborhoods of Salem and Eugene. Dry cleaners and gas stations are the routine findings on commercial corridors.

- Buyers of commercial and industrial property doing due diligence before closing
- Borrowers on SBA 504 and SBA 7(a) loans secured by real estate
- Banks and credit unions underwriting commercial mortgages

- Owners refinancing a commercial building
- Investors buying retail, warehouse, office, or multifamily sites
Oregon Cleanup Programs and Buyer Liability Protection
Oregon's Prospective Purchaser Agreement program is one of the most developed in the country. A buyer negotiates a settlement with DEQ before closing that limits liability in exchange for a defined cleanup contribution, and the agreement gets recorded. The Voluntary Cleanup Program issues No Further Action determinations for independent cleanups. Easements and equitable servitudes are recorded when cleanup depends on use restrictions, and Business Oregon's brownfield fund provides loans and grants for assessment and cleanup.
How Much Does a Phase 1 ESA Cost in Oregon?
Across the country a Phase 1 ESA runs from $1,500 to $6,000, and a plain commercial building on a single parcel lands near the low end of that range. Oregon pricing runs near the national middle, with Portland at the higher end. Properties near the Willamette need extra time to evaluate the Superfund allocation exposure.
What moves the price on a given property:
| Factor | Effect on price |
|---|---|
| Acreage and number of parcels | More ground to walk and more addresses to research |
| Current use | Industrial, automotive, and dry cleaning sites take longer to document |
| Historical use | A former gas station or manufacturing plant means more agency files to pull |
| Turnaround | A rush report in five to ten business days adds a premium |
| Age of the property | Older sites have more historical sources to review |
| Lender scope | Some banks and the SBA add deliverables beyond the ASTM standard |
A quote tied to the actual address is the only way to know the number for your property. Read the Phase 1 ESA cost guide for a closer look at pricing.
Phase 2 Environmental Site Assessment in Oregon
When a Phase 1 finds a Recognized Environmental Condition, the next step is a Phase 2 ESA. A Phase 2 puts soil borings, groundwater monitoring wells, or soil vapor probes in the ground and sends the samples to a lab. The scope depends on what the Phase 1 found, so a Phase 2 in Oregon can cost anywhere from a few thousand dollars for a handful of borings to well above $30,000 for a site with a plume.
The consultants in our network handle both phases. Ask for a Phase 2 quote when you submit your details, or read the Phase 2 ESA guide and the Phase 2 cost guide first.
Phase 1 ESA Questions From Oregon Buyers
How long does a Phase 1 ESA take in Oregon?
A standard Phase 1 ESA typically takes 2-4 weeks from start to delivery of the final report. Rush turnaround options are available, often within 5-10 business days, for an additional fee.
Who needs a Phase 1 Environmental Site Assessment?
Buyers, lenders, developers, and investors involved in commercial real estate transactions. SBA 7(a) and 504 loans typically require environmental due diligence, including a Phase 1 ESA. Banks and lenders typically require one for commercial property financing. It's also recommended when purchasing former industrial or commercial properties.
Do SBA loans require a Phase 1 ESA in Oregon?
SBA 7(a) and 504 loans typically require environmental due diligence for commercial property purchases, which usually includes a Phase 1 ESA. The report must comply with ASTM E1527-21 and be completed by a qualified environmental professional. Requirements can vary based on the property type, historical use, and lender policy.
What ASTM standard governs Phase 1 ESAs?
ASTM E1527-21 is the current standard for Phase 1 Environmental Site Assessments. It replaced E1527-13 and defines the scope, methodology, and reporting requirements. Compliance with this standard is necessary to qualify for the CERCLA innocent landowner defense.
Does a Phase 1 ESA include soil or groundwater testing?
No. A Phase 1 ESA is a non-invasive review of records, regulatory databases, historical sources, and a visual site inspection. It does not include physical sampling. If potential contamination is identified, a Phase 2 ESA with soil borings or groundwater monitoring may be recommended.
What happens if the report finds a Recognized Environmental Condition?
If the Phase 1 ESA identifies recognized environmental conditions (RECs), the next step is typically a Phase 2 ESA, which involves actual sampling and laboratory analysis of soil, groundwater, or air to confirm the presence and extent of contamination.
Can a Phase 1 ESA protect buyers from environmental liability?
Yes. A Phase 1 ESA conducted under ASTM E1527-21 helps establish the "innocent landowner" defense under CERCLA. This can protect buyers from liability for pre-existing contamination they were not aware of at the time of purchase.
What's the difference between Phase 1 and Phase 2 ESAs?
A Phase 1 ESA is a non-invasive investigation that reviews records and inspects the site visually. A Phase 2 ESA involves physical sampling (soil borings, groundwater monitoring wells, etc.) and laboratory analysis. Phase 2 is only needed when Phase 1 identifies potential contamination concerns.
Is a Phase 1 ESA required before buying commercial property in Oregon?
While not legally mandated for all purchases, most lenders, banks, and SBA lenders typically require a Phase 1 ESA before financing commercial real estate in Oregon. It is strongly recommended for any commercial, industrial, or redevelopment transaction to identify potential environmental liabilities.
