Environmental Due Diligence = Systematic assessment of environmental risks associated with real property acquisition, including historical contamination, regulatory liabilities, remediation requirements, and acquisition price adjustments.

Purpose:

• Identify and quantify environmental liabilities before acquisition
• Assess contamination risk severity and cleanup requirements
• Estimate remediation costs and timelines
• Determine regulatory pathway and approval requirements
• Develop liability allocation and insurance strategies
• Calculate acquisition price adjustments for environmental risk
• Protect buyer from hidden environmental costs

Key Components:

1. Phase I ESA interpretation (RECs, historical uses, data gaps)
2. Phase II ESA analysis (soil/groundwater sampling, contaminants)
3. Contamination risk scoring (HIGH/MEDIUM/LOW)
4. Cleanup cost estimation (risk-adjusted, scenario analysis)
5. Regulatory pathway analysis (MOE approval, Record of Site Condition)
6. Liability allocation strategies (vendor indemnity, holdback, insurance)
7. Acquisition price adjustment recommendations

Phase I Environmental Site Assessment (ESA)

Definition: Non-intrusive desk-top and visual inspection to identify recognized environmental conditions (RECs).

Key Outputs:

• REC (Recognized Environmental Condition): Evidence of release or threat of release of hazardous substances
• Historical REC (HREC): Past evidence of contamination, but no current threat
• Controlled REC (CREC): Current contamination being addressed through environmental remediation program

Phase I Process:

1. Records Review (80% of Phase I value):

- Historical property uses (manufacturing, retail, service stations, dry cleaners, etc.)

- Regulatory filings and violation notices

- Insurance claims history

- Prior ESA reports

- Lender environmental assessments

1. Site Inspection:

- Visual observation for storage tanks, hazmat, visible contamination

- Interview with property manager/tenant

- Neighboring property assessment (migration risk)

- Regulatory database searches (MOE, Ministry of Transportation)

1. Environmental Records Review:

- Spill reports and environmental incident database

- Regulatory enforcement actions

- Historical Sanborn Fire Maps

- Aerial photographs (20+ years)

- Town planning/zoning records

REC Identification:

• High Likelihood: Clear evidence of contamination
• Medium Likelihood: Historical use creates risk (e.g., former gas station)
• Low Likelihood: No evidence, but data gaps exist

Red Flags:

• Manufacturing history (especially chemicals, metals, textiles)
• Service stations and auto repair
• Dry cleaners and laundries
• Underground storage tanks (USTs)
• Spill reports or regulatory notices
• Adjacent contamination (migration risk)

Phase II Environmental Site Assessment (ESA)

Definition: Intrusive investigation with soil/groundwater sampling to quantify contamination and identify contaminants.

Phase II Process:

1. Sampling Plan Development:

- Target areas based on Phase I findings

- Soil boring locations (grid pattern)

- Depth of sampling (typical: 0-2 ft, 2-4 ft, 4-8 ft, >8 ft)

- Groundwater monitoring wells

- Quality assurance/control protocols

1. Sample Collection:

- Soil samples from identified risk areas

- Groundwater samples from monitoring wells

- Equipment blanks and duplicate samples

- Chain of custody documentation

1. Laboratory Analysis:

- Organic Contaminants: Petroleum hydrocarbons (PHC), PAHs, VOCs

- Inorganic Contaminants: Metals (lead, cadmium, zinc, arsenic), cyanide

- Analysis Standard: MOE Generic Quality Standards (GQS) or Soil and Groundwater Standards

- Report: Detailed analytical results with exceedance identification

1. Interpretation:

- Compare results to MOE Generic Quality Standards (residential/industrial)

- Identify exceedances (contamination above cleanup standard)

- Assess exposure pathways (soil ingestion, inhalation, groundwater ingestion)

- Evaluate risk to human health and environment

Contamination Categories:

• Non-Exceedance: Levels below MOE standards (no remediation required)
• Below-Ground Exceedance: Soil contamination, limited migration risk
• Above-Ground Exceedance: Readily accessible, higher risk
• Groundwater Exceedance: Water supply contamination, highest risk

MOE Generic Quality Standards (GQS)

Definition: Ontario Ministry of the Environment cleanup thresholds for soil and groundwater contamination.

Two-Tier Framework:

1. Tier 1 - Generic Criteria (no site-specific analysis required):

- Residential: Lower thresholds (children ingesting soil)

- Industrial: Higher thresholds (limited exposure)

- Agricultural: Variable (crop/livestock exposure)

1. Tier 2 - Site-Specific Analysis (if Tier 1 exceeded):

- Risk assessment based on actual exposure pathways

- Cleanup standard negotiated with MOE

- May be lower or higher than generic criteria

Key Contaminants - MOE Tier 1 Standards (Industrial):

```

Petroleum Hydrocarbons (PHC):

- PHC F1 (gasoline): 1,200 mg/kg soil, 2.4 mg/L water

- PHC F2 (diesel): 2,800 mg/kg soil, 1.5 mg/L water

- PHC F3-F4 (heavy oil): 4,000 mg/kg soil, 0.5 mg/L water

Metals (industrial standard):

- Lead: 500 mg/kg soil, 0.5 mg/L water

- Cadmium: 20 mg/kg soil, 0.008 mg/L water

- Zinc: 8,000 mg/kg soil, 30 mg/L water

- Arsenic: 100 mg/kg soil, 0.025 mg/L water

Volatile Organic Compounds (VOCs):

- Benzene: 0.5 mg/kg soil, 0.005 mg/L water

- Toluene: 2.5 mg/kg soil, 0.7 mg/L water

- Chloroform: 0.005 mg/kg soil, 0.007 mg/L water

```

Record of Site Condition (RSC)

Definition: Ontario regulatory certificate confirming contaminated property has been remediated to MOE standards and is fit for intended use.

RSC Process:

1. Phase I ESA: Identify RECs and contamination
2. Phase II ESA: Quantify contamination (if REC found)
3. Risk Assessment: Develop cleanup plan based on use
4. Remediation: Clean up to MOE standard (removal, capping, in-situ treatment)
5. Post-Remediation Sampling: Confirm cleanup achieved
6. Record of Site Condition (RSC): Submit to MOE with Professional Engineer sign-off
7. MOE Acceptance: RSC filed on property title, liability protection granted

Key Benefit: Once RSC filed, future owner cannot be liable for pre-existing contamination (with exceptions for non-disclosure).

Timeline: Typically 6-18 months from Phase II to RSC filing (varies by contamination severity and cleanup method).

Contamination Risk Scoring

Scoring Framework: Assess environmental liability risk across 4 dimensions

Dimension 1: Contamination Severity

```

- Below-ground, limited migration

- Single contaminant

- Non-aquifer groundwater

- Limited exposure risk

LOW:

- Soil contamination <2x MOE standard (borderline/minor)

- Deep soil (no ingestion risk)

- Non-hazardous materials

- No groundwater exceedance

- Minimal exposure risk

```

Dimension 2: Regulatory Complexity

```

HIGH:

• Record of Site Condition (RSC) preparation: $5,000-$15,000
• MOE RSC filing and approval: $1,000-$5,000

Cost Estimation Process

Step 1: Establish Contamination Profile

• Contaminant type (petroleum, metals, solvents)
• Contamination depth (surface, deep soil, groundwater)
• Estimated volume (cubic yards of contaminated soil)
• Concentration vs. standard (how far above MOE GQS)

Step 2: Select Remediation Approach

• Excavation (source removal) - lowest cost, fastest timeline
• Capping (institutional controls) - medium cost, long-term monitoring
• In-situ treatment (no excavation) - higher cost, longer timeline
• Combination approach (phased remediation)

Step 3: Quantify Volume

```

Volume = Area × Depth ÷ 27 (cubic yards)

Example: 10,000 sf property, contamination 8 feet deep

Volume = 10,000 sf × 8 ft ÷ 27 = 2,963 cubic yards

```

Step 4: Estimate Unit Costs

• Excavation: $20-$50/cy (depends on soil type, equipment access)
• Disposal: $75-$200/cy (depends on contaminant type, disposal facility location)
• Backfill: $10-$30/cy

Step 5: Calculate Total Cost

```

Total = (Excavation + Disposal + Backfill) × Volume + Contingency

Example: 2,963 cy contaminated soil

• Excavation: 2,963 × $35 = $103,705
• Disposal: 2,963 × $125 = $370,375
• Backfill: 2,963 × $20 = $59,260
• Professional Services: $30,000
• Subtotal: $563,340
• Contingency (25%): $140,835
• TOTAL ESTIMATE: $704,175

```

Step 6: Develop Scenario Range

• Conservative (High Cost): Use high unit costs, high volume, include contingency
• Expected (Medium Cost): Use mid-range unit costs, likely volume
• Optimistic (Low Cost): Use low unit costs, lower volume estimate

Example Range:

```

CONTAMINATION SCENARIO: Petroleum contamination, 3,000 cy

Optimistic: $300,000 (low cleanup costs, quick removal)

Expected: $500,000 (mid-range costs, standard cleanup)

Conservative: $750,000 (high costs, delays, extra monitoring)

Use Expected for budget/price adjustment

Use Conservative for risk reserve

```

Risk-Adjusted Cost Estimation

Formula:

```

Risk-Adjusted Cost = Expected Cost × (1 + Risk Factor)

Where Risk Factor =

- 0.0 to 0.25 (low risk: simple excavation)

- 0.25 to 0.50 (medium risk: some complexity)

- 0.50 to 1.0+ (high risk: multiple phases, regulatory delays)

```

Example - Medium Risk Petroleum Site:

```

Phase II Cost: $5,000

Risk Assessment Cost: $25,000

Remediation (Expected): $400,000

Professional Services: $30,000

Post-Remediation: $15,000

Subtotal: $475,000

Risk Factor: 0.35 (some regulatory complexity, phased approach)

Risk-Adjusted Total: $475,000 × 1.35 = $641,250

Range for negotiation: $475,000 - $800,000

```

MOE Approval Process for Contaminated Sites

Step 1: Determine Site Classification

```

Priority Level 1 (Immediate MOE Notification):

- Active spill or release

- Groundwater contamination

- Property near drinking water source

- Action: Immediate reporting required

Priority Level 2 (Standard Notification):

- Soil contamination discovered

- Property record updated

- Action: Notification within 30 days

Priority Level 3 (No Notification Required):

- Non-exceedance (meets GQS)

- Properly capped with controls

- Clean fill only

- Action: Proceed with use

```

Step 2: Phase I ESA

• Identify any RECs
• If no REC → Proceed with development (no further action)
• If REC found → Proceed to Phase II

Step 3: Phase II ESA (if REC identified)

• Soil/groundwater sampling
• Laboratory analysis
• Compare to MOE Generic Quality Standards (Tier 1)

Three Possible Outcomes:

Outcome A: Non-Exceedance (No contamination above standards)

• Proceed with development
• File Cleanup Completion Certificate (optional, recommended)
• Property clean for intended use
• Timeline: Immediate

Outcome B: Exceedance - Tier 1 Standard Applies

• Contamination above standard, but Tier 1 analysis sufficient
• Develop Remediation Plan
• Implement cleanup (removal, capping, or treatment)
• File Record of Site Condition (RSC)
• Timeline: 6-12 months

Outcome C: Exceedance - Tier 2 Analysis Required

• Contamination above Tier 1, but site-specific risk analysis may allow higher standard
• Commission Risk Assessment by qualified professional
• Submit Risk Assessment to MOE for approval
• If approved, Tier 2 standard becomes cleanup target (may be higher than Tier 1)
• Implement remediation to Tier 2 standard
• File RSC with Risk Assessment and MOE approval
• Timeline: 12-24 months (MOE review period 3-6 months)

Timeline Estimates

Non-Exceedance (Fast Track):

• Phase I: 2-4 weeks
• Phase II: 4-8 weeks
• Analysis: 1-2 weeks
• Total: 2-3 months

Tier 1 Exceedance (Standard Track):

• Risk Assessment: Not required (use generic standard)
• Remediation Plan: 2-4 weeks
• Remediation: 2-6 months (depends on scope)
• Post-Rem Sampling: 2-4 weeks
• RSC Filing: 1-2 weeks
• Total: 6-12 months

Tier 2 Exceedance (Extended Track):

• Phase I-II: 6-8 weeks
• Risk Assessment: 8-12 weeks
• MOE Review (Risk Assessment): 12-16 weeks
• Remediation Plan: 2-4 weeks
• Remediation: 2-6 months
• Post-Rem Sampling: 2-4 weeks
• RSC Filing: 1-2 weeks
• Total: 12-24 months

Seller Warranties & Indemnity

Objective: Protect buyer from hidden environmental costs and regulatory surprises.

Seller Representations (in purchase agreement):

```

The Seller represents and warrants:

1. No Environmental Contamination:

"Seller has no knowledge of any environmental contamination

at the property above MOE Generic Quality Standards."

1. Compliance History:

"Seller has not received any environmental violation notices

or cleanup orders from MOE or any environmental agency."

1. Hazardous Material Management:

"Seller has properly managed all hazardous materials,

including fuel storage, waste disposal, and chemical handling,

in compliance with all environmental laws."

1. Prior ESAs:

"Seller has provided Buyer with all prior Phase I/II ESAs,

Risk Assessments, and environmental reports in Seller's possession."

1. Spill/Release History:

"Seller has not received any spill reports or environmental

incident notices at the property."

```

Indemnity Structure (post-closing protection):

```

Seller agrees to indemnify Buyer for:

- Pre-closing environmental contamination discovered post-closing

- Costs to remediate pre-existing contamination

- Regulatory fines/penalties for pre-closing violations

- Cleanup costs under MOE enforcement action

- Third-party claims for pre-closing contamination

Indemnity Protection:

- Survival Period: 3-7 years post-closing

- Coverage Cap: $500,000 - $2,000,000

- Threshold: $10,000-$25,000 (seller not liable for minor issues)

- Basket: Cumulative claims must exceed threshold

Example:

"Seller shall indemnify Buyer for all environmental liabilities

arising from pre-closing contamination, capped at $1,000,000,

with $25,000 threshold, surviving 5 years post-closing."

```

Holdback/Escrow Strategy

Objective: Retain purchase price funds to cover environmental remediation if discovered post-closing.

Structure:

```

Purchase Price: $10,000,000

Less: Environmental Holdback: $500,000 (5% of price)

Paid at Closing: $9,500,000

Held in Escrow: $500,000

Holdback Release:

- Option 1: Upon receipt of clean Phase I ESA (60 days post-closing)

- Option 2: Upon filing of RSC (6-12 months post-closing)

- Option 3: Percentage release (50% after Phase I, 50% after Phase II)

If contamination discovered:

- Holdback funds used to pay for remediation

- Any excess holdback released to seller

- Any shortfall responsibility of seller (indemnity)

```

Typical Holdback Amounts (% of purchase price):

• No Phase I completed: 5-10%
• Phase I clean (no REC): 1-2%
• Phase I with HREC only: 2-3%
• Phase I with REC, Phase II pending: 5-15%
• Phase II with minor exceedance: 2-5%
• Phase II with significant exceedance: 10-20%

Insurance Solutions

Seller's Liability Insurance (pre-closing):

• Environmental liability policy on existing contamination
• 3-year tail coverage
• Cost: $5,000-$50,000 (depends on contamination severity)
• Covers seller's indemnity obligations

Buyer's Cost-Cap Policy (post-closing):

• Covers remediation costs beyond estimate
• Protects against regulatory action surprises
• Typical coverage: $250,000-$1,000,000
• Cost: $10,000-$100,000
• Duration: 3-5 years

Pollution Liability Policy (ongoing):

• Covers operational pollution risks (tenant operations)
• Covers accidental releases during lease term
• Relevant for: Manufacturing, auto repair, dry cleaners, etc.
• Cost: $1,000-$10,000 per year

Integration: Often uses combination of seller indemnity + holdback + insurance.

Price Adjustment Formula

```

Adjusted Price = Base Price - Environmental Cost + Timing Adjustment

Where:

Base Price = Contract purchase price

Environmental Cost = (Remediation + Professional Services) × Risk Factor

Timing Adjustment = Cost of delay to project timeline

```

Environmental Discount Calculation

Step 1: Estimate Cleanup Cost (using Cost Estimation Framework above)

• Expected scenario: $X
• Conservative scenario: $Y
• Use Expected cost minus contingency for negotiation

Step 2: Calculate Risk Factor

• Site complexity (regulatory approval ease)
• Cleanup technology feasibility
• Remediation timeline impact
• Factor: 0.8 to 1.25 (0.8 = high confidence, 1.25 = high uncertainty)

Step 3: Calculate Environmental Discount

```

Environmental Discount = Estimated Cost × Risk Factor × Discount Rate

Discount Rate:

- 85% (for low risk, straightforward cleanup): Discount 85% of cost

- 75% (for medium risk, some complexity): Discount 75% of cost

- 65% (for high risk, regulatory uncertainty): Discount 65% of cost

Rationale: Buyer should discount cleanup costs because:

- Estimates may be overstated (early-stage assumptions)

- Buyer may have operational synergies (in-house expertise)

- Buyer can phase cleanup over time (cost of capital savings)

- Certainty premium worth something

```

Example 1: Low Risk Petroleum Site

```

Phase II Result: Petroleum contamination, 2,000 cy soil,

Tier 1 standard applies

Cleanup Estimate:

- Phase II already completed: $0

- Excavation/Disposal: $350,000

- Professional Services: $20,000

- Post-Rem Sampling: $10,000

Expected Cost: $380,000

Risk Factor: 0.95 (low uncertainty, straightforward excavation)

Risk-Adjusted Cost: $380,000 × 0.95 = $361,000

Discount Rate: 85% (low regulatory complexity)

Environmental Discount: $361,000 × 0.85 = $306,850

Price Adjustment: REDUCE PRICE BY $306,850

Negotiation Range:

- Buyer's opening: Reduce by $400,000

- Seller's opening: Reduce by $200,000

- Likely outcome: Reduce by $300,000-$350,000

```

Example 2: Medium Risk with Tier 2 Analysis Required

```

Phase II Result: Petroleum + metals, groundwater exceedance,

Tier 2 Risk Assessment required

Cleanup Estimate:

- Phase II completed: $0

- Risk Assessment: $30,000

- Remediation (expected): $600,000 (phased over 18 months)

- Long-term monitoring: $30,000/year × 5 years = $150,000

- Professional Services: $50,000

Expected Cost: $830,000

Additional considerations:

- 12-month MOE approval timeline

- Project delay: 12 months

- Cost of delay (delay to development): $500,000+

Total Environmental Impact: $1,330,000

Risk Factor: 1.1 (medium uncertainty, regulatory approval needed)

Risk-Adjusted Cost: $830,000 × 1.1 = $913,000

Discount Rate: 75% (medium regulatory complexity)

Environmental Discount: $913,000 × 0.75 = $684,750

PLUS Delay Cost (present value, 12 months at 5% WACC): $50,000

Total Price Adjustment: REDUCE PRICE BY $734,750

Negotiation Range:

- Buyer's opening: Reduce by $900,000

- Seller's counter: Reduce by $400,000

- Likely outcome: Reduce by $650,000-$800,000

```

Example 3: High Risk - Seller Remediation Required

```

Phase II Result: SEVERE: Heavy metals (lead >5,000 mg/kg),

Groundwater exceed by 100x, adjacent property impact

Cleanup Estimate:

- Phase II, Risk Assessment, regulatory coordination: $75,000

- Remediation (conservative): $2,000,000

- Long-term monitoring (10 years): $200,000

- Potential third-party claims: $500,000 (uncertain)

Expected Cost: $2,775,000

Risk Factor: 1.3 (high uncertainty, regulatory action likely)

Risk-Adjusted Cost: $2,775,000 × 1.3 = $3,607,500

This exceeds typical discount rate thresholds.

Negotiation Options:

Option 1: Reduce Price: $2.5-3.0M (not fully covering risk)

Option 2: Seller Remediation: Seller remediates pre-closing,

Buyer receives clean property with RSC

Option 3: Post-Closing Holdback: Buyer retains $3-4M escrow

for remediation, Seller guarantees completion

Option 4: REJECT: Contamination too severe/risky

Recommendation: OPTIONS 2 or 3 (transfer risk back to seller)

```

This skill works closely with:

Settlement Analysis Expert

• When environmental costs trigger valuation disputes
• Calculating probability-weighted settlement outcomes
• Negotiating environmental liability allocation
• Quantifying risk in settlement scenarios

Example:

```

Phase II shows significant contamination, cleanup estimate $1.5M

Seller disputes cost estimate, claims $500K sufficient

Options:

1. Accept $500K adjustment (vs. $1.5M estimated)

2. Seller provides indemnity capped at $750K

3. Use escrow approach with phased release

Settlement Analysis:

- Probability seller's estimate correct: 20%

- Probability buyer's estimate correct: 60%

- Probability intermediate ($900K): 20%

Expected outcome: (0.20 × $500K) + (0.60 × $1.5M) + (0.20 × $900K)

= $100K + $900K + $180K = $1.18M discount

```

Expropriation Compensation Expert

• When contaminated property is expropriated/acquired
• Calculating compensation deduction for environmental liability
• Determining "market value" for contaminated property
• Assessing severance damages for neighboring contamination

Example:

```

Expropriation/Negotiation Scenario:

- Market value (uncontaminated): $5,000,000

- Contamination cleanup cost: $1,500,000

- Risk adjustment (75% of cost): $1,125,000

Adjusted fair market value = $5,000,000 - $1,125,000 = $3,875,000

Compensation to owner limited to $3,875,000

```

Step 1: Obtain Environmental Documents

Required Documents:

• Phase I ESA (if completed)
• Phase II ESA (if available)
• Risk Assessment (if Tier 2)
• Record of Site Condition (if filed)
• Spill/release reports
• Environmental compliance certificates
• Historical property records

Source Documents:

• Contract environmental provisions
• Seller disclosure statements
• Title insurance environmental exceptions
• Regulatory database searches (MOE, TRA)

Step 2: Interpret Phase I ESA Findings

Analysis Questions:

1. Are RECs identified? (Yes/No)
2. If REC: What type (current, historical, controlled)?
3. What properties were adjacent (contamination migration risk)?
4. What data gaps exist (historical records incomplete)?
5. Is Phase II ESA recommended? (Yes/No)

Risk Assessment from Phase I:

• No REC: Low risk, proceed with development
• HREC Only: Low-medium risk, verify no current threat
• REC Identified: Medium-high risk, Phase II required
• CREC (Controlled): Check status of remediation program

Step 3: Analyze Phase II ESA Results

If Phase II completed:

1. What contaminants detected?
2. Soil vs. groundwater exceedance?
3. Concentration vs. MOE Generic Quality Standard (Tier 1)?
4. Does Tier 1 standard apply, or Tier 2 analysis needed?
5. Estimated volume of contaminated material?

Risk Categorization:

• Non-Exceedance: No cleanup required, property clean
• Minor Exceedance (Tier 1): Straightforward cleanup, 6-12 month timeline
• Significant Exceedance (Tier 2): Complex cleanup, 12-24 month timeline, MOE approval required
• Severe Exceedance: Remediation risk, third-party impact, 24+ month timeline

Step 4: Estimate Cleanup Costs

Using framework above:

• Identify cleanup method (excavation, capping, treatment)
• Quantify volume (cubic yards of contaminated soil)
• Apply unit costs ($/cy for excavation, disposal, etc.)
• Add professional services, monitoring, permitting
• Apply risk adjustment factor
• Develop conservative/expected/optimistic scenarios

Step 5: Develop Regulatory Pathway Timeline

• If Non-Exceedance: Timeline = 0 months (immediate use)
• If Tier 1: Timeline = 6-12 months (Phase II done, remediation straightforward)
• If Tier 2: Timeline = 12-24 months (Risk Assessment, MOE approval, remediation)

Step 6: Calculate Price Adjustment

Using formula above:

• Risk-adjusted cleanup cost × Discount Rate = Environmental Discount
• Reduce purchase price by calculated discount
• Develop negotiation range (conservative to optimistic)

Step 7: Develop Liability Allocation Recommendation

Allocation Decision Tree:

```

Cleanup Cost < $100,000 AND Timeline < 6 months?

→ Buyer absorbs (minimal risk)

Cleanup Cost $100K-$500K AND Timeline 6-12 months?

→ Seller indemnity (3-5 year) + standard holdback (2-3%)

Cleanup Cost $500K-$2M AND Timeline 12-24 months?

→ Seller indemnity + 5-10% holdback + cost-cap insurance

Cleanup Cost > $2M OR Timeline > 24 months?

→ Seller remediation pre-closing OR reduce price 50%+

and post-closing indemnity + escrow

```

MOE Generic Quality Standards (Most Common)

Industrial/Commercial Land:

• Petroleum Hydrocarbon F2 (diesel): 2,800 mg/kg soil
• Lead: 500 mg/kg soil
• Arsenic: 100 mg/kg soil
• Benzene: 0.5 mg/kg soil

Tier 2 Analysis Triggers:

• Any groundwater exceedance
• Soil exceedance > 5x Tier 1 standard
• Potential third-party migration
• Potential human exposure (e.g., above-ground contamination)

Cost Thresholds

```

Environmental Discount Magnitude:

< $100K: 1-2% of property value (ignore or modest adjustment)

$100K-$500K: 2-5% of property value (standard negotiation)

$500K-$2M: 5-15% of property value (significant adjustment)

> $2M: 15%+ of property value (major deal impact)

```

Timeline Impact on Value

```

Cleanup Timeline:

< 6 months: No delay to project (no timeline cost)

6-12 months: Modest delay cost (opportunity cost)

12-24 months: Significant delay (6-12 months lost use)

> 24 months: Major project delay (NPV impact)

Timeline Cost = (Lost Revenue/Profit) × (Months of Delay ÷ 12)

Use Case 1: Phase I ESA Review - Petroleum Service Station

Scenario: Buyer acquiring 15,000 sf service station property. Phase I ESA completed shows property was service station for 40 years (1970-2010), no prior Phase II, petroleum staining noted in parking lot.

Analysis:

```

Phase I Finding: REC identified (historical petroleum use, visible staining)

Risk Level: MEDIUM (petroleum service station, but closed >10 years)

Phase II Recommended: YES

Likely Finding: Soil petroleum contamination, probably <5,000 cy

Estimated Cleanup:

- Phase II ESA: $6,000

- Soil sampling (20 borings): $10,000

- Excavation/disposal (3,000 cy @ $75): $225,000

- Professional services: $25,000

- Post-rem sampling: $8,000

Total: $274,000

Risk Factor: 0.95 (petroleum straightforward to remediate)

Risk-Adjusted Cost: $260,300

Discount Rate: 85% (Tier 1 standard, no regulatory complexity)

Environmental Discount: $221,255

RECOMMENDATION:

1. Make offer conditional on Phase II ESA

2. Use Phase II results to finalize price

3. If Phase II confirms estimate, reduce price by $200,000-$250,000

4. If Phase II worse than expected, re-negotiate or withdraw

5. Request seller indemnity for 3 years, $25K threshold

```

Use Case 2: Phase II ESA Analysis - Manufacturing Property

Analysis:

```

Phase II Finding:

- Soil metals exceedance, Tier 1 applies

- Estimated 8,000 cy contaminated soil (8-15 feet depth)

```

Environmental Risk Level: LOW-MEDIUM

Phase II ESA Required: Recommended (data gap - 1995 Phase II not available)

Cost for Phase II ESA:

- New Phase II ESA (4 borings, soil/groundwater): $8,000

Likely Result: Non-exceedance or minor exceedance

- If non-exceedance: Proceed, minimal adjustment

- If minor (< 2x standard): Excavate ~500 cy, cost ~$50-75K

Estimated Price Impact: $0-$50,000 discount

Timeline Impact: 4-8 weeks for Phase II, no delay to occupancy

Recommendation:

1. Commission Phase II ESA as due diligence

2. If non-exceedance: No price adjustment

3. If minor exceedance: Reduce price by $40,000-$60,000

4. If significant exceedance: Re-evaluate, may require Tier 2

5. Historical dry cleaning = typical REC, should resolve easily
