What the EP actually does
Historical aerials and city directories. Regulatory databases. Interviews. A walk of the plating line, the tank farm, the dry well, the drum pad. A written opinion on RECs, HRECs, and CRECs. ASTM’s E1527-21 page is the practice standard (Source: ASTM E1527-21). EPA AAI is the legal wrapper (Source: EPA / 40 C.F.R. Part 312).
What Phase I will not finish
Soil and groundwater data. That is Phase II. ISRA filings. Permit transfers. A cleanup cost. Census CBP 2023’s 284,452 establishments include thousands of finishing and tank histories that still start with a walk, not a slogan (Source: Census CBP).
Components generally stale after 180 days. Time the engagement to the exclusive, not to a hope that the 2018 report “looks fine.”
| Report | Intrusive? | Typical output |
|---|---|---|
| Phase I ESA | No | REC opinion, AAI support |
| Phase II ESA | Yes | Sample data on named RECs |
| Remedial estimate | Separate | Cost, not a Phase I chapter |
Who orders it, and when?
Usually the buyer, often as an LOI condition, sometimes with a seller contribution. Lenders and CDCs will not take a stale report. Jason Taken is a business broker. Educational information only. The EP and environmental counsel own the opinion.
How to brief the Environmental Professional on a plant
Send a process narrative, not a brochure. Name plating, solvents, tanks, foundry sand, paint booths, pits, dry wells, and off-site storage. Name the years the building was industrial, even if your entity arrived in 2014. Give the EP access to the roof, the oil-water separator, and the room everyone calls “the old lab.” A Phase I that never saw the finishing annex is a Phase I of a different property.
Sellers should not coach interviews. The EP will talk to the person who has been there longest. If that person says “we used to dump there,” the report will say so. Hide-the-pit is how RECs become walk-aways instead of priced data.
Buyers should not treat a “no REC” conclusion as a permit transfer. Air, RCRA, and stormwater are different work. ISRA is different work. AAI’s 180-day stale rule still applies even if the walk was thorough (Source: EPA / 40 C.F.R. Part 312).
Budget time. A good Phase I on a messy industrial site is weeks, not a weekend. Pair it with the exclusive. Pair it with the 504 occupancy path if a building loan is in the stack. The glossary only defines the report. Phase I and Phase II sequences it.
Isolation
The glossary keeps Phase I off Phase II and off ISRA. The FAQ holds the question. When the walk needs to happen this quarter, book a confidential intro call.
Data gaps and the off-site story that is not on the deed
A locked room, a missing tank-closure letter, or an inaccessible crawl space is a data gap. It is not a no-REC. Budget access or budget the gap as risk. Ask the EP to list gaps in plain English in the transmittal, not only in appendix J.
A shop that sent drums to a now-famous site may have a records problem even if the current floor is tidy. Tell the EP. Historical sources exist so you do not discover that in a later lawsuit. A CIM can say “current Phase I to be ordered inside the exclusive” without calling the floor clean. Bring the process list, the oldest industrial year you know, and any prior reports. Those three brief the EP. Phase I and Phase II sequences the work. After the walk noun is straight, a confidential intro call is the conversion path.
What Phase I is not
It is not Phase II. It is not ISRA. It is not a sampling report. It is not a no-REC certificate when the transmittal lists data gaps. ASTM E1527-21 is the practice standard. AAI is the EPA wrapper. Components generally stale after 180 days (Source: EPA / 40 C.F.R. Part 312). A CIM that dates a 2024 walk as current for a 2026 close is advertising a cover letter.
How it shows up: a current study promised inside the exclusive, with the process list the EP has not yet heard — plating, degreasing, underground tanks, off-site disposal. Budget weeks, not a weekend, on a messy industrial site. Pair it with the exclusive. Pair it with the 504 occupancy path if a building loan is in the stack. The Environmental Professional writes the opinion. A broker briefs the process list.
