Environmental Diligence Under the New SBA SOP: Your 2025 Roadmap to Faster Approvals

In partnership with

Nothing kills an SBA deal faster than environmental surprises. A missing Phase II report, an outdated assessment, or overlooked PFAS contamination can add weeks to your closing timeline—or derail the deal entirely.

The good news? The SBA's updated Standard Operating Procedures (SOP 50 10 8, effective June 2025) provide the clearest guidance yet on exactly what environmental work is required and when. Here's your complete roadmap to navigate the requirements and keep your deals moving.

What's Changed: The Key Updates You Need to Know

1. Clearer Scope Definition

The SBA clarified that environmental policies apply specifically to the real estate being acquired, refinanced, or improved with loan proceeds—not every tangential property. This eliminates confusion about what needs environmental review.

2. Updated Standards

All Phase I Environmental Site Assessments (ESAs) must now follow ASTM E1527-21 (not the older E1527-13 standard). The updated standard includes enhanced historical research and adjoining property review requirements.

3. Refreshed Industry List

SOP 50 10 8 updates the "Environmentally Sensitive Industries" NAICS list in Appendix 6, giving lenders clear guidance on when industry risk alone triggers enhanced due diligence.

4. PFAS Integration

Following EPA's May 2024 designation of PFOA and PFOS as CERCLA hazardous substances, PFAS must now be evaluated like other contamination risks in Phase I assessments.

5. Tighter Timing Requirements

All environmental assessments and tests must be completed within one year of submission to the SBA. No more recycling old reports.

The 2025 Environmental Due Diligence Decision Tree

Here's the step-by-step process every SBA loan must follow:

Step 1: Site Visit + Environmental Questionnaire (EQ)

Lender responsibility: Must conduct at least one site visit
Required documentation: Complete SBA Environmental Questionnaire
What to look for: Current use, storage practices, staining, drainage, tanks (UST/AST), and obvious red flags

Step 2: NAICS Code Screening

Check current and historical site use against the Environmentally Sensitive Industries list:

Oil/gas extraction
Mining operations
Heavy construction
Gasoline stations
Certain food manufacturing
Chemical processing
If match = automatic Phase I ESA required

Step 3: Choose Your Assessment Level

Option A: RSRA (Records Search with Risk Assessment)

When appropriate: Very low-risk properties with clean use history
Requirements: Desk-based review by Environmental Professional (EP)
Outcome: Must conclude "Low Risk" or escalate to Phase I

Option B: Phase I ESA

When required: Any sensitive NAICS, red flags from site visit, or elevated RSRA risk
Standard: Must follow ASTM E1527-21
Timeline: Complete within one year of submission

Option C: Phase II ESA

Mandatory triggers: Current or former dry cleaning operations
Typical triggers: Any Recognized Environmental Conditions (RECs) from Phase I
Scope: Soil, groundwater, and vapor testing as needed

Special Property Types: Enhanced Requirements

Gas Stations and Fuel Facilities

Always required:

Phase I ESA following ASTM E1527-21
Recent UST system integrity/tightness tests
Cathodic protection verification
Leak detection records
Operator training certifications
State UST compliance documentation

Pro tip: Treat gas stations as automatic two-step processes. Budget for both Phase I and compliance documentation upfront.

Dry Cleaners (Current or Former)

Mandatory Phase II ESA covering:

Soil contamination assessment
Groundwater testing
Soil vapor analysis
Focus on chlorinated solvents (PCE) and petroleum products

Critical: Even "former" dry cleaners require Phase II investigation due to long contaminant half-lives.

Child-Occupied Facilities

Required testing (within one year):

Lead risk assessment
Drinking water lead testing
Examples: Daycares, schools, medical facilities serving children

Timing trap: The one-year currency requirement on lead testing catches many deals off-guard. Schedule early.

The PFAS Reality: What You Need to Know Now

Since EPA's CERCLA designation in May 2024, PFAS contamination must be evaluated in Phase I assessments. Environmental Professionals should now assess:

Historical operational uses (firefighting foam, industrial processes)
Water source proximity to known PFAS sites
Manufacturing operations that may have used PFAS
Military/airport proximity (AFFF usage)

If PFAS risks are identified, expect targeted sampling recommendations and potential deal delays.

Environmental Professional Requirements

Who can perform the work:

Must meet ASTM's Environmental Professional definition
Requires specific education, training, and experience
SBA allows lender-employed EPs (though many prefer third-party for objectivity)

Report currency:

All assessments within 12 months of SBA submission
Child-occupied facility testing within 12 months
UST compliance testing must be current

Common Deal Killers and How to Avoid Them

1. Aging Reports

The problem: Submitting 18-month-old Phase I reports or stale UST tests The solution: Keep all environmental work within the one-year window; schedule early for child-occupied facilities

2. Dry Cleaner Surprises

The problem: Missing historical solvent use that requires mandatory Phase II The solution: Assume legacy solvent use if there's any historical evidence and order Phase II immediately

3. Incomplete Gas Station Documentation

The problem: Missing UST compliance records that SBA requires The solution: Request complete UST compliance package upfront; don't assume "current operations = compliant"

4. Outdated ASTM Standards

The problem: Using E1527-13 instead of required E1527-21 The solution: Verify all vendors are using current ASTM E1527-21 standard

Your Environmental Due Diligence Checklist

For Every Deal:

☐ Complete site visit and Environmental Questionnaire
☐ Screen NAICS codes against sensitive industries list
☐ Verify Environmental Professional qualifications
☐ Confirm ASTM E1527-21 compliance for Phase I work
☐ Ensure all reports/tests within 12 months of submission

Gas Stations Additional:

☐ UST system integrity tests (current)
☐ Cathodic protection verification
☐ Leak detection system records
☐ Operator training documentation
☐ State regulatory compliance proof
☐ Any corrective action history

Dry Cleaners Additional:

☐ Phase II ESA (mandatory)
☐ Soil contamination assessment
☐ Groundwater testing
☐ Soil vapor analysis
☐ Historical solvent use documentation

Child-Occupied Facilities Additional:

☐ Lead risk assessment (within 12 months)
☐ Drinking water lead testing (within 12 months)
☐ Schedule testing early in process

Lender vs. Borrower Responsibilities

Lender Must:

Perform or verify site visit
Ensure Environmental Questionnaire completion
Select appropriate assessment level
Verify EP credentials and ASTM compliance
Confirm report currency
Compile special property documentation

Borrower Must:

Complete Environmental Questionnaire accurately
Provide site access for visits and testing
Furnish operational records (chemicals, waste, permits)
Allow Phase II testing if required
Cooperate with lead assessments and water sampling

Best Practices for Faster Approvals

1. Front-Load the Assessment Decision

If there's any indication of sensitive use or contamination risk, skip RSRA and go straight to Phase I. The time saved avoiding re-work usually justifies the modest cost difference.

2. Schedule Child-Occupied Testing Immediately

The one-year currency requirement often becomes the critical path. Book lead assessment and water testing as soon as you identify a child-occupied facility.

3. Budget Two-Step for High-Risk Properties

For gas stations and dry cleaners, budget time and cost for both Phase I and additional requirements upfront. These properties have the highest likelihood of conditions or delays.

4. Update Your Vendor Network

Ensure all environmental consultants are using ASTM E1527-21 and understand PFAS evaluation requirements. Outdated approaches cause rejections.

5. Keep Detailed Documentation

Maintain clear records of all environmental decisions, consultant qualifications, and report dates. SBA reviewers will verify compliance with current requirements.

Cost and Timeline Planning

Typical Costs:

RSRA: $1,500-$3,000
Phase I ESA: $3,000-$6,000
Phase II ESA: $8,000-$25,000+ (depending on scope)
Lead assessments: $1,000-$2,500
UST compliance review: $2,000-$5,000

Typical Timelines:

RSRA: 1-2 weeks
Phase I ESA: 2-3 weeks
Phase II ESA: 4-8 weeks (including lab time)
Lead testing: 2-3 weeks
UST compliance: 1-2 weeks (if records available)

Red Flags That Require Immediate Attention

Watch for these issues that commonly derail SBA approvals:

Historical Red Flags:

Former gas station/automotive use
Industrial manufacturing operations
Dry cleaning operations (any timeframe)
Chemical storage or processing
Underground storage tanks (active or removed)

Current Red Flags:

Chemical odors or staining
Stressed vegetation
Nearby contaminated sites
Active USTs without proper documentation
PFAS-related operations (airports, military, manufacturing)

The Bottom Line: Prevention Beats Remediation

Environmental due diligence under the current SBA SOP is more standardized than ever, but it's also more rigorous. The key to success is understanding the requirements upfront and building proper assessment scope, timing, and budget into every deal.

Success formula:

Know your triggers: NAICS codes, property types, historical uses
Plan for currency: All work within 12 months of submission
Budget appropriately: High-risk properties need Phase II planning
Use current standards: ASTM E1527-21 and PFAS awareness
Document everything: EP qualifications, report dates, compliance proof

The deals that close on time are the ones where environmental due diligence is treated as a critical path item from day one, not an afterthought when the loan package is being assembled.

Your Next Steps

Immediate actions:

Update your intake forms to include NAICS screening and environmental questionnaire
Verify vendor compliance with ASTM E1527-21 and PFAS requirements
Build environmental timelines into your standard loan process
Train your team on the special requirements for gas stations, dry cleaners, and child-occupied facilities

Environmental compliance doesn't have to slow down your deals—but cutting corners or missing requirements absolutely will. In today's SBA environment, the lenders who understand these requirements and plan accordingly are the ones closing loans on schedule.
