Phase I Environmental Site Assessments
Environmental due diligence available nationwide
Understand a property’s environmental history and conditions before buying, financing or planning its future use. Based in Las Vegas, OGI Environmental provides Phase I Environmental Site Assessments nationwide for property buyers, owners and lenders.
Our assessments follow ASTM E1527-21 and identify Recognized Environmental Conditions through records review, site observations, interviews and professional evaluation.
What the assessment includes
- Review of historical and regulatory information concerning the property and nearby sites.
- Site reconnaissance to observe current conditions and indications of past activities.
- Interviews with owners, occupants and other appropriate sources.
- A written report documenting the assessment, findings and conclusions.
A Phase I ESA does not include soil or groundwater sampling. If findings warrant further evaluation, we can discuss a proposed Phase II investigation and appropriate next steps.
Transaction Screens
OGI also provides Transaction Screens in accordance with ASTM E1528-22. These offer a more limited review of a property’s environmental conditions and are not a substitute for a Phase I Environmental Site Assessment.
Before selecting this service, confirm the requirements of your lender and other intended report users. Contact OGI to discuss which assessment is appropriate for your property and transaction.
A scope and schedule that fit your transaction
Tell us the property address, the intended use of the report, your lender’s requirements and your target closing date. We will confirm the proposed scope, fee and anticipated schedule before work begins.
Timing depends on property access, available records and project requirements. Contacting us early helps identify information needed to move the assessment forward.
Additional services
Asbestos, lead-based paint, radon, mold, wetlands and other concerns may require separate evaluations outside the standard Phase I scope. We can discuss those needs when preparing your proposal.
For broader property due diligence, OGI also offers Property Condition Assessments of commercial and industrial buildings nationwide.
