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 Pennsylvania
The state records for a Pennsylvania Phase 1 come from Pennsylvania Department of Environmental Protection, searched alongside the federal databases every Phase 1 covers.
The Department of Environmental Protection publishes its records through eFACTS and a set of map viewers, and it also publishes cleanup notices in the Pennsylvania Bulletin every week. A Phase 1 in Pennsylvania has to look beyond the environmental files, though. Coal mining and oil and gas history are held by different bureaus, and a property in the western or northeastern part of the state can sit over an abandoned mine or next to an orphan well that no environmental database mentions.
The Pennsylvania lists a consultant checks for a property in Pennsylvania:
- eFACTS. DEP's facility and permit system, which covers storage tanks, waste facilities, and enforcement actions.
- Land Recycling Program (Act 2) records. Notices of Intent to Remediate, final reports, and relief from liability approvals for voluntary cleanups.
- Hazardous Sites Cleanup Act list. State-led cleanup sites under Pennsylvania's own superfund law.
- Storage Tank database. Registered underground and aboveground tanks and reported releases.
- Abandoned mine land and mine subsidence maps. Bureau of Abandoned Mine Reclamation inventories and mine map coverage used to flag subsidence and mine drainage risk.
- Oil and gas well records. Conventional and unconventional wells, including the state's growing list of orphan and abandoned wells.
Common Sources of Contamination on Pennsylvania Properties
Pennsylvania has more abandoned oil and gas wells than any other state, with the first commercial oil well drilled in Titusville in 1859 and well over a century of drilling since. Anthracite and bituminous coal mining left subsidence, refuse piles, and acid mine drainage across dozens of counties. Steel and heavy manufacturing shaped Pittsburgh, Bethlehem, and the river valleys, and slag fill from those mills is common under commercial parcels. Philadelphia carries the same historic fill and manufactured gas plant issues as other old East Coast cities, plus refineries along the Delaware and Schuylkill rivers.
Who Orders a Phase 1 ESA in Pennsylvania
- 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
- Developers acquiring land or buildings for redevelopment
- Attorneys handling purchase agreements and lease negotiations
- Owners refinancing a commercial building
- Investors buying retail, warehouse, office, or multifamily sites
Pennsylvania Cleanup Programs and Buyer Liability Protection
Act 2, the Land Recycling and Environmental Remediation Standards Act, is the state's voluntary cleanup law. A remediator picks a cleanup standard, either background, the statewide health standard, or a site-specific standard, and completing the work earns relief from liability that transfers to future owners. Notices of Intent to Remediate appear in the Pennsylvania Bulletin and a consultant will check those notices for the property and its neighbors. An environmental covenant is recorded when the cleanup relies on use restrictions.
How Much Does a Phase 1 ESA Cost in Pennsylvania?
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. Pennsylvania pricing runs in the middle of the national range. Properties in mining regions or on former mill land cost more because mine map research and fill characterization add hours.
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 Pennsylvania
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 Pennsylvania 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 Pennsylvania Buyers
How long does a Phase 1 ESA take in Pennsylvania?
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 Pennsylvania?
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 Pennsylvania?
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 Pennsylvania. It is strongly recommended for any commercial, industrial, or redevelopment transaction to identify potential environmental liabilities.
