Environmental Desktop Review (Desktop Screen)

Short answer: An environmental desktop review, or desktop screen, is a records-based look at a property: government databases and historical sources, read by an Environmental Professional, with no site visit. No ASTM standard governs it; it cannot satisfy EPA’s All Appropriate Inquiries rule or support CERCLA protection. Ours costs $199, arrives next business day and is fully credited toward a Phase I on the same property ordered within 30 days.

What a desktop screen is, and what it is not

A desktop screen tells you, before you spend more on due diligence, whether public records and the property’s history point to contamination. Government databases show regulated activity and reported releases on and near the property. Historical sources, such as aerial photographs, city directories and fire insurance maps, show earlier uses, including uses older than the programs that track them. Federal law first required owners to report underground storage tanks by May 8, 1986, and tanks taken out of operation on or before January 1, 1974 were exempt (EPA’s 1985 notification rule).

An environmental database report is the government-records part in raw form: a vendor’s map, counts of listed sites by database and distance, and the record details, as Environmental Risk Information Services (ERIS) describes its report. It is data, not an assessment: a 2023 NETR Online report says its risk ratings are “for illustrative purposes only.” A desktop screen adds the historical sources and a professional’s reading of both.

No ASTM standard defines a desktop review. ASTM subcommittee E50.02 maintains practices for the Phase I (E1527-21, and E2247-23 for forestland or rural property), the Transaction Screen (E1528-22) and the Phase II (E1903-19), but none for a desktop review (checked October 2026).

Scope therefore varies by firm. The EI Group’s desktop review, as the firm described it in 2016, includes an owner or operator interview. A3 Environmental’s screen searches federal and state databases within 1/8 mile, against the 1/2-mile to 1-mile distances EPA’s All Appropriate Inquiries (AAI) rule sets for the cleanup and leaking tank lists shown below.

A screen also cannot meet the AAI rule, which requires the Environmental Professional (EP) to conduct interviews and a visual inspection of the property along with the records reviews (40 CFR 312.21(b)). AAI is one requirement for the landowner liability protections under CERCLA, the federal Superfund law, including the bona fide prospective purchaser (BFPP) defense that matters for most buyers (40 CFR 312.1). A Phase I is the Environmental Professional’s part of that requirement, and the buyer’s own inquiries under 40 CFR 312.22, such as the search for environmental cleanup liens, complete it. Continuing obligations apply after closing, and your attorney should advise on the defense.

How lenders, consultants and data vendors use desktop screens

Lenders set their own rules. The Office of the Comptroller of the Currency’s Commercial Real Estate Lending handbook expects a bank’s environmental policy to set “risk thresholds based on property type, use, and loan amount,” with methods ranging from questionnaires or screenings and records reviews to site visits and testing (pages 66-67). A bank’s own CERCLA secured creditor exemption does not require an AAI-standard evaluation, the handbook notes, though an AAI-compliant study can provide the best assessment of a property’s condition. That is why one bank may ask for a Phase I where another accepts a screen.

Consultants sell screens for that tiered use. Partner ESI describes desktop reports as an initial screen, often used “for low-risk assets or low-dollar transactions.” The EI Group names refinances, loan restructures and loans not secured by the real estate as typical fits. LightBox, which sells Environmental Data Resources (EDR) reports, offers a risk rating it markets as documentation for the loan file.

Prices and terms are as listed on each firm’s own website on October 19, 2026. On that date, $199 was below every published desktop screen price we found.

When a desktop screen is the right first step

• Before an offer or letter of intent, to decide whether to pursue the property and how much due diligence time to ask for.
• Portfolio triage. Screen every property, then order Phase Is where the records point.
• Pricing a deal. A former fueling, dry cleaning or industrial use on the property means budgeting for a Phase I and possibly a Phase II. In EDR’s 2018 survey, consultants said close to one quarter of Phase I ESAs lead to a Phase II.
• Gauging what a Phase I will find. A screen cannot clear a site, but the listings and past uses it does find are the issues a Phase I would have to resolve.
• A conventional loan on low-risk collateral, where the lender’s credit policy allows a records-only screen.

When a desktop screen is not enough

• You are buying and want CERCLA protection. Only an inquiry that meets AAI, in practice a Phase I together with your own inquiries, satisfies the requirement, and EPA’s 2019 enforcement guidance says buyers cannot perform AAI after acquiring the property. This holds for all-cash buyers too: the protection does not depend on having a lender. A screen can still come first if the Phase I is finished before closing.
• Your lender requires a Phase I or names ASTM E1527-21.
• It is an SBA 7(a) or 504 loan secured by commercial real estate. SOP 50 10 8.1 builds its required steps from five report types (Environmental Questionnaire, Records Search with Risk Assessment or RSRA, Transaction Screen, Phase I and Phase II), and the word “desktop” does not appear in it. A current or known prior use matching an Appendix 6 North American Industry Classification System (NAICS) code requires a Phase I at any loan amount, unless the property is a unit in a non-industrial building of 4 or more units, where the lender may skip the NAICS check; on-site dry cleaning, current or past, still requires a Phase I followed by a Phase II for any property, including such a unit (Paragraph E.6.b). With no match, or for such a unit, a loan over $250,000 requires at least the Questionnaire plus an RSRA, and a loan of $250,000 or less may begin with the Questionnaire alone, adding an RSRA if the answers warrant it (Section A, Chapter 5, Paragraphs E.4.a and E.4.b; Appendix 4).
• The property is or was a gas station, dry cleaner, manufacturer, junkyard or landfill. ASTM says even its transaction screen, which includes a site visit, does not suit properties that handle large volumes of chemicals (ASTM E1528-22, Note 1). Order the Phase I.

How to read an environmental database report

Work through a report in this order.

1. Start with the summary table. Reports count records by database and distance band, such as under 1/8 mile, 1/8 to 1/4 mile, 1/4 to 1/2 mile and 1/2 to 1 mile.
2. Read listings at the property’s own address first, then its neighbors. Beyond the property itself, the AAI rule looks for small and large quantity hazardous waste generators and registered tanks only on adjoining properties (40 CFR 312.26).
3. Know what each list means. A listing is not the same as contamination.

Reports may also list very small quantity generators, EPA’s category for 100 kilograms or less of hazardous waste a month (EPA); the AAI list does not name them. An EP may change any of these distances with a documented reason, including groundwater flow direction (312.26(d)). ASTM E1527-21 sets its own minimum search distances, and EPA’s comparison of the two notes one difference: E1527-21 searches engineering and institutional control registries for the property only.

4. Read the status, date and substance of each release. In the December 2023 NETR Online report posted on the City of Redlands website, the one leaking tank record, 1/4 to 1/2 mile away, described a gasoline leak reported in 2003, with soil and an aquifer used for drinking water listed as the media of concern; San Bernardino County closed the case in 2008. A closed case on the property itself still matters if contamination was left in place subject to controls, such as a land use restriction: ASTM E1527-21 treats that as a controlled REC (Partner ESI glossary).
5. Check direction and elevation. ERIS and EDR reports list each site’s distance, direction and elevation relative to the property. A site upgradient, where groundwater flows toward the property, generally matters more than one downgradient, because contamination can travel with groundwater. Surface topography can hint at shallow groundwater flow, a 2007 EDR report notes, but site-specific well data show it best.
6. Read the unmapped list. Records with incomplete addresses go in a separate list, often called orphan sites. The same EDR report states that these sites “are not considered” in its analysis. Scan the list for the property’s street and its neighbors’ names.
7. Check the data dates, and what is missing. Lists update on their own schedules; EPA’s UST Finder map shows state tank data as of 2018-2019. A missing record does not mean nothing happened: older or unreported uses can show up only in historical sources, interviews or a site visit.

Checking records yourself. EPA’s Cleanups in My Community maps the Superfund, RCRA corrective action, brownfields and federal facility cleanups EPA tracks, but excludes state and locally funded ones. Its Enforcement and Compliance History Online (ECHO) covers compliance and enforcement at regulated facilities. Leaking tank and state cleanup records are kept by each state; the Redlands record came from California’s GeoTracker.

Our desktop screen: price, timing and delivery

Our desktop screen is $199 flat for the scope shown above, delivered the next business day after you authorize, and we confirm the date before you authorize. The opinion is written by an Environmental Professional who meets 40 CFR 312.10. The price is below the published prices above because we built proprietary internal technology that collects and organizes the regulatory and historical records the day an order is authorized, so the Environmental Professional reviews an organized record instead of assembling one. If we miss the delivery date we commit to for a reason within our control, our on-time guarantee refunds the full $199.

Worked example. Suppose the screen flags a former filling station across the street and you decide to order a Phase I. The full $199 is credited toward a Phase I on the same property ordered within 30 days, so for a standard-scope property the two reports cost $1,495 in total, the price of the Phase I alone. The cost of starting with the screen is time: 1 business day for the screen plus 5 for the Phase I (counted from authorization and confirmed site access), or 6 in all if you authorize the Phase I the day the screen arrives, against 5 for a Phase I ordered first.

For the next step, see what a Phase I includes and how Phase I prices compare.
