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 Texas
Properties in San Antonio, TX fall under Texas Commission on Environmental Quality along with the federal databases every Phase 1 covers.
The Texas Commission on Environmental Quality holds most of the records a Phase 1 ESA in Texas needs. The exception is oil and gas. Wells, pipelines, and saltwater disposal sites belong to the Railroad Commission of Texas, and in much of the state a consultant will spend as much time in Railroad Commission well records as in TCEQ files. Both agencies publish searchable map viewers.
The Texas lists a consultant checks for a property in San Antonio, TX:
- TCEQ Central Registry. The master index of regulated entities, which links a property to any permit, registration, or enforcement record the agency holds.
- PST and LPST databases. Petroleum Storage Tank registrations and Leaking Petroleum Storage Tank cases, with case status and closure dates.
- Voluntary Cleanup Program and Innocent Owner/Operator Program lists. Sites that have entered or completed the VCP, and properties that hold an Innocent Owner certificate.
- Dry Cleaner Remediation Program registry. Registered dry cleaner facilities and drop stations, ranked for state-funded cleanup.
- Municipal Setting Designations. City ordinances that prohibit the use of shallow groundwater for drinking. An MSD changes how a nearby plume is evaluated.
- Railroad Commission well records. Plugged, orphaned, and active oil and gas wells, plus pipeline locations, searched through the RRC public GIS viewer.
Common Sources of Contamination on San Antonio, TX Properties
The industries that shaped San Antonio include military base operations, aircraft maintenance and repair, petroleum refining, cement and aggregate mining, food processing, light manufacturing, and dry cleaning. Consultants who work here pay close attention to Kelly Air Force Base and Port San Antonio Superfund site, Brooks City-Base redevelopment area, Lackland Air Force Base and surrounding area, Beckmann Quarry and North Side industrial zone, and East Side industrial corridor along Rigsby Avenue, where past land use raises the odds of a finding.
Oil and gas touches property in every part of Texas. Abandoned wells sit under subdivisions in the Permian Basin and around Houston, and pipeline easements cross ranch land that is now being platted. The Gulf Coast has a century of petrochemical refining and shipping around Houston, Beaumont, and Corpus Christi. Cotton farming in West Texas and the Blackland Prairie used arsenic-based pesticides for decades. In the cities, gas stations, dry cleaners, and auto repair shops are the usual suspects, and Dallas and Fort Worth both have a legacy of lead smelting and metal plating.

Texas Cleanup Programs and Buyer Liability Protection
TCEQ's Voluntary Cleanup Program issues a Certificate of Completion that releases future owners and lenders from liability for the contamination addressed. The Innocent Owner/Operator Program certifies that a property's contamination came from an off-site source, which is a common outcome when a plume from a neighboring gas station crosses the line. Cleanup levels come from the Texas Risk Reduction Program, and the choice of a residential or commercial standard changes what a buyer will be allowed to build.
How Much Does a Phase 1 ESA Cost in San Antonio, TX?
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. Texas is a competitive market with a lot of qualified consultants, and pricing for a standard commercial parcel lands in the middle of the national range. Rural tracts with oil and gas history cost more because well records take time to trace.
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 San Antonio, TX
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 San Antonio, TX 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 San Antonio, TX Buyers
How long does a Phase 1 ESA take in San Antonio, TX?
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 Texas?
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 Texas?
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 Texas. It is strongly recommended for any commercial, industrial, or redevelopment transaction to identify potential environmental liabilities.
