Short answer: A Phase I is required at any loan amount when a current or known prior use is on the Appendix 6 list in SBA SOP 50 10 8.1. With no match, loans over $250,000 need the lender’s Environmental Questionnaire plus a records-only Records Search with Risk Assessment (RSRA). A Transaction Screen, which adds a site visit, is the minimum if the current owner or operator will not sign the Questionnaire.
Which environmental report the SBA requires is set by Section A, Chapter 5, Paragraph E of SOP 50 10 8.1, the U.S. Small Business Administration’s (SBA) Standard Operating Procedure (SOP) for 7(a) and 504 loans. The three reports differ in trigger, scope, reliance rule and price, and each has its own rule for what happens when it finds a problem. To apply the rules to one loan, use the SBA environmental requirement checker.
SOP 50 10 8.1 took effect October 1, 2026. Its current text was published September 25, 2026, replacing a version issued August 14, 2026 that never took effect. The SBA’s September notice applies it to applications received on or after October 1; the earlier August notice said loan numbers issued on or after that date. Our word-by-word comparison found the environmental rules unchanged in substance from the 2025 SOP, which still governs applications submitted through September 30, 2026.
Which environmental report does the SBA require?
Check every row, not only the first one that fits. The use rows apply at any loan amount and can stack: a former dry cleaner matches Appendix 6 and also needs a Phase II, and a gas station adds Appendix 7. The last three rows apply when no NAICS code matches, or when the property is a unit in a multi-unit building (see below). On those rows, if the current owner or operator will not sign the Questionnaire, at least a Transaction Screen takes its place.
Paragraph E.2 calls these minimum standards and says internal lending policy may require more, so a lender can ask for a Phase I where the SBA would accept less. This table keeps only what decides between the three reports; our guide to SBA environmental requirements sets out every step in order, including contamination, special use facilities and the 504 differences.
| If the property | What the SBA calls for | SOP 50 10 8.1 |
|---|---|---|
| Has a current or known prior use that matches an Appendix 6 NAICS code | Phase I, regardless of loan amount | Para. E.4.a.i |
| Is a gas station (NAICS code beginning with 457) | Phase I, plus Appendix 7 where it applies | Para. E.4.a.i; Appendix 7 |
| Houses a business that sells, supplies or dispenses fuel, with no code match | A Phase I “should always be obtained” | Appendix 6, footnote |
| Has, or once had, on-site dry cleaning that uses, used or likely used chlorinated or petroleum-based solvents | Phase I followed by a Phase II covering soil, groundwater and soil vapor | Para. E.6.b |
| Is a car-wash-only facility | Transaction Screen, “an acceptable starting point” | Appendix 6, entry 8111 |
| Has no match, and the loan is up to and including $250,000 | Environmental Questionnaire | Para. E.4.a.ii.a |
| Has no match, and the loan is over $250,000 | Environmental Questionnaire and RSRA | Para. E.4.a.ii.b |
| Has a current owner or operator who will not sign the Questionnaire | Transaction Screen; on a loan over $250,000, the SOP does not say whether an RSRA is also needed | Appendix 4, “Environmental Questionnaire” |
NAICS is the North American Industry Classification System, and the check covers known prior uses, not only the current one. A shop on a former gas station lot can need a Phase I, and a strip center whose past tenant ran an on-site dry cleaner can need a Phase I and a Phase II. Laundry and dry cleaning (8123) counts only “if dry cleaning operations have ever existed on site,” so on our reading a laundromat that has never had dry cleaning on site (no dry cleaning plant and no self-service drycleaning machines) does not match. Our SBA NAICS code lookup searches all 55 Appendix 6 entries and their conditions.
Appendix 7 applies to loans secured by property or equipment currently used to operate a gas station or commercial fueling facility. It requires the Phase I to be performed by an independent Environmental Professional (EP), a person who meets the test in 40 CFR 312.10, and to document whether the station complies with tank and equipment testing requirements.
Two more rules sit beside the table. For a unit in a non-industrial building of 4 or more units, such as an office condominium, the lender may skip the NAICS check and go straight to the loan-amount rows (Paragraph E.4.a; Appendix 4, “Multi-Unit Building”). The dry cleaning row still applies to such a unit, because Paragraph E.6.b covers “any Property” with on-site dry cleaning, current or past. A child-occupied facility built before 1978, such as a daycare, also needs a lead risk assessment and lead-in-drinking-water testing within one year of the date the SBA loan number is issued, repeated for each new loan (Paragraph E.6.a).
A desktop screen is not one of these reports: Paragraph E.4 names only the Questionnaire, RSRA, Transaction Screen, Phase I and Phase II, and the word “desktop” does not appear in the SOP. A desktop report counts only if it meets every element of the SBA’s RSRA definition, including the low, elevated or high risk class (Appendix 4).
RSRA vs Transaction Screen vs Phase I, side by side
A Phase I ESA is a Phase I Environmental Site Assessment. AAI is the U.S. Environmental Protection Agency’s (EPA) All Appropriate Inquiries rule, 40 CFR Part 312. CERCLA is the Comprehensive Environmental Response, Compensation, and Liability Act, the federal Superfund law.
| Question | RSRA | Transaction Screen | Phase I ESA |
|---|---|---|---|
| Standard | SBA’s own definition (Appendix 4) | ASTM E1528-22, plus SBA additions (Appendix 4) | ASTM E1527-21 and AAI |
| What it covers | Government databases listed in 40 CFR 312.26, plus historical sources back to first developed use or 1940, whichever is earlier | Owner or operator interview, site visit, ASTM questionnaires A and B, government records and historical sources | Government records, historical sources, site reconnaissance, interviews and the user’s own inquiries |
| Consultant visits the site | No; the lender visits for its Questionnaire | Yes, supervised by an EP | Yes |
| Who performs it | An EP makes the risk assessment and is named in the report | For SBA loans, an EP (ASTM alone lets the user, a lender or others do it) | An EP, or staff under an EP’s supervision; an EP signs |
| What the result says | Low, elevated or high risk | No further investigation warranted, or more is warranted | Opinion on recognized environmental conditions, plus SBA’s required conclusion |
| Meets AAI | No | No | Yes, when done to E1527-21 within EPA’s time limits and with the user’s own inquiries |
| Where the SBA path calls for it | No Appendix 6 match and loan over $250,000, or a Questionnaire shows more investigation is warranted | Current owner or operator will not sign the Questionnaire; car-wash-only sites | Appendix 6 match; dry cleaning; RSRA not low risk; screen calls for more; “should” for fuel sellers |
| SBA Appendix 5 reliance letter | Not required; the form has no RSRA box | Required | Required |
| Age limit for the SBA | Within one year of the SBA loan number date | Same | Same, “notwithstanding” EPA’s 180-day rule |
| Age limit to count as AAI | Does not apply | Does not apply | 5 components within 180 days before acquisition; the rest within 1 year |
| Prices other firms published, October 19 or 20, 2026 | $575-$875 | $930 to about $1,950; few firms publish one | $1,500 at the low end of one firm’s typical range; from $1,650 (one New Jersey, New York and Pennsylvania firm); ranges such as $2,200-$4,000 |
| Our price and standard time | $695, 2 business days | $795, 4 business days | $1,495, 5 business days |

RSRA vs Phase I: what the records search leaves out
An RSRA is the SBA’s records-only report: a search of the government databases that 40 CFR 312.26 lists for an AAI Phase I and of historical sources such as aerial photographs, city directories and fire insurance maps, followed by an EP’s rating of the property as low, elevated or high risk for contamination. Our SBA RSRA page lists each element the SBA definition requires and the database search distances.
A Phase I adds the rest of the inquiry. 40 CFR 312.20(b) lists five components that must be done within 180 days before acquisition: interviews, searches for recorded environmental cleanup liens, the government records review, a visual inspection of the property and adjoining properties, and the EP’s declaration. Of those five, an RSRA covers only the government records search. A Phase I also takes in the buyer’s own inquiries under 40 CFR 312.22, such as specialized knowledge and whether a price below fair market value reflects contamination.
The SOP leaves the meaning of low, elevated and high risk to the EP and sets only the consequence: a result that is “anything other than ‘low risk’” requires a Phase I (Paragraph E.4.c). An RSRA never satisfies the SBA where an Appendix 6 match or on-site dry cleaning, current or past, requires a Phase I. Where the business sells, supplies or dispenses fuel, the SBA says a Phase I “should always be obtained” (Appendix 6, footnote). That is why we check the uses you give us against Appendix 6 before an RSRA starts.
Will my lender accept an RSRA instead of a Phase I? The SBA sets a floor, and each lender sets its own policy above it. The Office of the Comptroller of the Currency (OCC), which supervises national banks, says in its examiner handbook that a bank’s environmental policy should set “risk thresholds based on property type, use, and loan amount for determining when and what type of due diligence is required” (OCC Comptroller’s Handbook, printed page 67, PDF page 71). Two lenders can therefore ask for different reports on the same building. Ask before you order.
Transaction Screen vs Phase I: when a screen is enough
A Transaction Screen follows ASTM E1528-22, a practice for limited due diligence on property where a Phase I is initially deemed unnecessary. ASTM’s public summary says a screen looks for potential environmental concerns rather than recognized environmental conditions, will not satisfy AAI, and should not be used to qualify for CERCLA landowner liability protections (Sections 1.1, 1.1.1, 1.2.1, 4.1 and 4.2.2). EPA’s list of standards that may be used to comply with AAI does not include it (40 CFR 312.11).
ASTM lets the user, a lender, a broker or others perform a screen without an EP’s judgment (Section 4.3). The SBA requires an EP to perform it, supervise the site reconnaissance and state a conclusion, with the database and historical records attached and the Appendix 5 reliance letter (Paragraph E.3; Appendix 4). On our screens, an Environmental Professional supervises the site visit and states the conclusion, and the report attaches the database and historical records it relied on. Our Transaction Screen Assessment page compares the ASTM and SBA versions line by line.
ASTM says a screen may be especially appropriate for rural, non-industrial or undeveloped property or, subject to a lender’s criteria, for financing property expected to have few environmental concerns (Section 1.3.2). It says a screen is generally not suitable where large volumes of chemicals are used, handled, stored or disposed of, now or in the past, as in manufacturing, vehicle fueling, dry cleaning, metal plating, junkyards and landfills (Note 1).
Order a Phase I ESA first when the use involves chemicals, fuel or vehicle repair, when your lender’s policy names ASTM E1527-21, when you are buying and plan to rely on a CERCLA defense, or when a red flag is likely. A screen that calls for more work leads to a Phase I, and skipping straight to a Phase II needs an advance exception from the SBA Environmental Committee, which the committee may grant case by case (Paragraph E.4.d).
SBA RSRA vs Transaction Screen (TSA): which one applies
Under SBA rules these two are not alternatives chosen by price. The RSRA path runs on the lender’s Environmental Questionnaire, which the lender completes or reviews after at least one site visit and a good-faith attempt to interview the current owner or operator, who must sign it. The SBA accepts the ASTM E1528-22 Questionnaire A in its place (Appendix 4).
If the current owner or operator will not sign, the Questionnaire “cannot be used,” and the lender must obtain at least a Transaction Screen (Appendix 4). The only other trigger the SOP names for a screen is a car-wash-only facility.
- Who visits. For an RSRA the lender visits for its Questionnaire and the EP works from records. For a Transaction Screen the visit is part of the report, supervised by an EP.
- What comes back. An RSRA returns a risk class. A Transaction Screen has none; the EP concludes either that the risk is so minimal no further investigation is warranted, or that more is warranted.
- Reliance. A Transaction Screen needs the Appendix 5 letter. An RSRA does not.
The SOP leaves one case open. On a loan over $250,000 with no NAICS match, Paragraph E.4.a.ii.b sets the minimum at a Questionnaire and an RSRA, and the SOP does not say whether a Transaction Screen also stands in for the RSRA when the current owner or operator refuses to sign. Put that question to local SBA counsel for the area where the property is located, as Paragraph E.9 directs, before ordering.
If counsel cannot answer before closing, a Phase I covers more than either reading of the minimum requires. That is our inference from Paragraph E.2, which calls the rules minimum standards, not a rule the SOP states.
What each result means for the loan
| Report | Result | What the lender must do |
|---|---|---|
| Environmental Questionnaire | Contamination unlikely; no further investigation warranted | Keep it in the file (Para. E.4.b). On a loan over $250,000, the RSRA is still required under Para. E.4.a.ii.b |
| Environmental Questionnaire | Further investigation warranted | Obtain at least an RSRA (Para. E.4.b) |
| RSRA | Low risk, with a clean Questionnaire | Keep both in the loan file (Para. E.4.c) |
| RSRA | Elevated or high risk | Obtain a Phase I (Para. E.4.c) |
| Transaction Screen | No further investigation warranted | Keep the screen and the review in the loan file (Para. E.4.d) |
| Transaction Screen | Further investigation warranted | Obtain a Phase I; going straight to a Phase II needs an advance exception (Para. E.4.d) |
| Phase I | No further investigation warranted | Keep the Phase I and the review in the loan file (Para. E.4.e) |
| Phase I | Further investigation warranted, typically a Phase II | Proceed as the EP recommends, or request an exception at EnvironmentalAppeals@sba.gov (Para. E.4.e) |
The SBA “will require compliance with all of an Environmental Professional’s recommendations,” including housekeeping measures such as secondary containment, decommissioning monitoring wells and sealing floor drains (Paragraph E.4.e).
Worked example. Take a $600,000 office loan with no Appendix 6 match, where the SBA minimum is the lender’s Questionnaire plus an RSRA. If our $695 RSRA comes back low risk and the Questionnaire is clean, that minimum is met for $695 (Paragraph E.4.c). If it comes back elevated risk, the SBA requires a Phase I. The full $695 is credited toward a Phase I on the same property ordered within 30 days, so the Phase I costs $800 more and the two reports total $1,495, the price of the Phase I alone.
What the RSRA-first route can cost is time: 2 plus 5 business days, against 5 for a Phase I ordered first. Where a Transaction Screen is the minimum, starting with our $795 screen and ordering the Phase I within 30 days also totals $1,495, but takes 4 plus 5 business days. If the property’s history already points to a problem, order the Phase I first.
Does any of these reports protect a buyer under CERCLA?
Not on its own. Only the Phase I counts, and only as one of several requirements, because neither the RSRA nor the Transaction Screen meets AAI. For most buyers the relevant protection is the bona fide prospective purchaser (BFPP) defense, defined in 42 U.S.C. 9601(40). AAI carried out before acquisition is one of its eight criteria, and a Phase I to ASTM E1527-21 is built to meet that one requirement, not the others (ASTM E1527-21, Sections 1.1 and 1.1.3).
The defense also depends on the buyer’s own inquiries and on what EPA calls continuing obligations after closing (EPA lender liability fact sheet, page 2), which the statute lists as reasonable steps, cooperation and access, compliance with land use restrictions, and more.
This is where the loan decision and the liability decision split. The SBA may accept an RSRA for the loan while the buyer still wants a Phase I for the BFPP defense. EPA says purchasers “cannot perform all appropriate inquiries after acquiring contaminated property” (EPA’s 2019 enforcement discretion guidance, page 5), so that Phase I has to be finished before closing. Your attorney should advise on the defense itself.
Age limits and the reliance letter
Every SBA environmental report must be dated within one year of the date the SBA loan number is issued (Paragraph E.3). For a Phase I, the SBA applies that rule “notwithstanding the EPA’s regulations on updating Phase I ESAs after 180 days,” and notes that parties “may still wish to strictly comply with EPA’s regulatory timeframes” (Appendix 4).
EPA requires the whole inquiry within one year before acquisition and the five components above within 180 days (40 CFR 312.20). Both clocks run from the component dates; ASTM E1527-21 says the report date “generally does not represent” them (Section 4.6.3). A Phase I with an eight-month-old site visit can satisfy the SBA and still need an update for the buyer.
Paragraph E.3 requires every Transaction Screen, Phase I and Phase II to be “accompanied by the Reliance Letter in Appendix 5,” even when the report is addressed to the lender. The letter is a fixed form whose wording “may not be modified” (Appendix 4), with check boxes for those three reports only. It lets the lender and the SBA rely on the report and states that it “is not an update.”
An RSRA “need not be addressed to the SBA and need not be accompanied by a Reliance Letter” (Appendix 4). We include the Appendix 5 letter with our Transaction Screens and Phase Is at no charge.
Six claims about these reports, checked against the rules
We found each of these claims in current guides, consultant pages, forum answers or search summaries in October 2026. Each is wrong, or true only in part, under SOP 50 10 8.1 or the ASTM and EPA rules it relies on.
- “Loans over $250,000 need an RSRA or a Transaction Screen.” With no Appendix 6 match, Paragraph E.4.a.ii.b sets the minimum at a Questionnaire plus an RSRA. The SOP names a Transaction Screen only when the current owner or operator will not sign the Questionnaire (Appendix 4) and as “an acceptable starting point” for a car-wash-only facility (Appendix 6).
- “Loans under $250,000 never need a Phase I.” An Appendix 6 match requires a Phase I regardless of the loan amount (Paragraph E.4.a.i), and on-site dry cleaning with chlorinated or petroleum-based solvents, current or past, requires a Phase I and a Phase II on any property (Paragraph E.6.b). Only a unit in a non-industrial building of 4 or more units may skip the NAICS check (Paragraph E.4.a), and on any loan an RSRA rated elevated or high leads to a Phase I (Paragraph E.4.c).
- “An RSRA rates a property low or high.” The scale has three steps (low, elevated and high), and only a low rating with a clean Questionnaire ends the inquiry (Paragraph E.4.c).
- “An RSRA needs only one historical source.” Only if that source reaches far enough back. The SBA sets a coverage test, not a count: the sources should identify uses back to the first developed use or 1940, whichever is earlier, the EP reviews as many as are necessary, reasonably ascertainable and likely to be useful, and the report includes every source relied on (Appendix 4).
- “Every SBA environmental report needs the reliance letter.” Only Transaction Screens, Phase Is and Phase IIs do (Paragraph E.3).
- Out-of-date rules. A $150,000 RSRA threshold, NAICS 447 for gas stations, ASTM E1527-13 and E1528-14 all still circulate. The threshold is $250,000; Appendix 6 uses 457, the 2022 NAICS code for gasoline stations and fuel dealers, which replaced 2017’s 447 for gasoline stations; EPA recognized E1527-13 only until February 13, 2024 (40 CFR 312.11); and the SBA cites E1528-22.
What each report costs and how long it takes
Prices below were published by each firm on its own website, as listed on October 19 or 20, 2026. Our turnaround runs from authorization, and for the Transaction Screen and Phase I from confirmed site access.
| Report | Published elsewhere | Ours | Our turnaround |
|---|---|---|---|
| RSRA | Kross Inspectors $575 web rate, 1-3 business days; A3 Environmental $850 flat, 5-day standard, 8 days or less from order; Phase Enviro $875, for a listing that also includes an environmental questionnaire | $695 flat | 2 business days, or next business day for $150 more |
| Transaction Screen | Few firms publish a price. A3 Environmental says about $1,950 on its blog and 10-15 business days on its service page; two other firms’ pages listed $930 (on a page that also says to contact the office for a price) and “starting at $1,200” | $795 flat | 4 business days, or 3 for $250 more |
| Phase I | AAI Environmental says these reports typically cost $1,500-$5,000; Phase 1 Environmental Consulting NJ from $1,650 for New Jersey, New York and Pennsylvania work; Geotill $1,900 flat, 2-3 weeks; A3 Environmental $2,200-$4,000, 2-3 weeks | $1,495 flat | 5 business days, or 3 for $400 more |
Kross Inspectors publishes a lower RSRA price than ours. Our $795 Transaction Screen was below every published Transaction Screen price we found in October 2026. The Phase I figures in the table start at $1,500, and most of the Phase I prices and ranges in our Phase I cost guide ran about $1,800 to $5,000; ours is $1,495 flat for standard scope. LightBox’s May 2023 survey of environmental professionals put the average Phase I on a conventional property at $3,083 and 16 business days.
Other firms publish standard Phase I turnarounds as short as 5 business days, such as Kross Inspectors.
The flat Phase I price covers standard scope: one parcel, up to 5 acres, up to 3 buildings and 50,000 square feet, and a current use that is not heavy industrial or manufacturing. We can charge less for a Phase I because we built proprietary internal technology that collects and organizes the regulatory and historical records the day an order is authorized, so an Environmental Professional who meets 40 CFR 312.10 reviews an organized record instead of assembling one. For contamination rules and the 504 and 7(a) differences, see our guide to SBA environmental requirements.
