Why it matters

Signed by a qualified Environmental Professional — every time.

  1. 01
    Qualification

    AAI-Qualified Environmental Professional

    Matthew holds the EPA AAI-Qualified Environmental Professional credential. Every Phase I ESA is prepared to the current ASTM E1527-21 standard — the version lenders and attorneys need for BFPP liability protection.

  2. 02
    Accountability

    Personally Walked & Signed

    Matthew conducts the site visit himself and personally signs the EP declaration on every report. You know exactly who stood on your property.

  3. 03
    Integrity

    No Subcontractors. No Outsourcing.

    Your file is never handed off to a third-party technician or remote reviewer. The same qualified EP who walks the site writes and signs the opinion.

Built for how you actually use it

The right report for your role in the deal.

Same rigor, same standard — presented in a way that speaks to what you specifically need to see.

For Real Estate Attorneys

Reports written to survive scrutiny — not just fill a checklist.

  • Every Phase I is built to meet the current ASTM E1527-21 standard, the version EPA requires (since Feb 2024) for CERCLA All Appropriate Inquiries and Bona Fide Prospective Purchaser (BFPP) liability protection.
  • Clear, defensible EP declarations and documentation your firm can hand to opposing counsel, title, or a court.
  • We work backwards from your closing date — not ours. If it needs to be on your desk Friday, tell us Monday.
What's included

A rigorous four-part process, delivered without drama.

Every Phase I follows the same disciplined sequence — the reason our reports hold up under bank, title, and legal review.

  1. Historical research

    Sanborn maps, aerial photos, city directories, EPA ECHO, NYSDEC and local agency records — the paper trail that shows what a site has been used for over its lifetime.

  2. On-site walkthrough

    A qualified Environmental Professional walks the property and adjoining parcels, documenting current conditions, storage, staining, drums, USTs, and any indicators of concern.

  3. Interviews

    Conversations with current owners, occupants, and where appropriate, past staff or neighbors — capturing knowledge that isn't in any public database.

  4. E1527-21 report + EP declaration

    A written report with findings, opinions, conclusions, and the signed Environmental Professional declaration required for AAI / BFPP protection.

Timing

Your closing date is our deadline.

Most Phase I ESAs are delivered within 5 business days. Phase II timelines depend on lab turnaround, but we coordinate scheduling so nothing sits idle. Tighter timeline? Tell us the date and we'll work the file around it.

If we find something

A finding isn't a dead end.

If our Phase I identifies a Recognized Environmental Condition (REC), you won't be left staring at a report wondering what happens next. We walk you through what the finding means for your specific transaction — whether it warrants a Phase II, what scope that would look like, and how it may impact your closing timeline.

The goal is simple: no surprises at the closing table, and a clear path forward whatever the finding.

Straightforward guidance on next steps — Phase II scoping available in-house.
FAQ

The questions we actually get asked.

Straight answers about standards, qualifications, timelines, and what happens if a finding shows up.

Yes. Every Phase I ESA we deliver is built to ASTM E1527-21, the standard EPA has required since February 2024 for CERCLA All Appropriate Inquiries and Bona Fide Prospective Purchaser (BFPP) liability protection. We do not deliver reports to the older E1527-13 standard.
