You Won an EPA Brownfields Grant. Here Is How to Procure the Phase I ESA Correctly

Winning an EPA Brownfields grant is the hard part. Spending it correctly is the part nobody warns you about.

If your community, land bank, redevelopment authority, tribe, or nonprofit just received an EPA Brownfields Assessment Grant, you now have a procurement problem that sits squarely on the desk of someone who is not an environmental specialist. Every Phase I Environmental Site Assessment (ESA) you pay for with those grant funds has to be conducted in compliance with the All Appropriate Inquiries (AAI) Final Rule at 40 CFR Part 312, and it has to follow the current ASTM standard. Get the procurement wrong and you face two consequences: a disallowed expenditure and, worse, the loss of the federal liability protection the assessment was supposed to secure.

This is not the general “what is a Phase I” explainer. If you want the full breakdown of what the standard covers and when a Phase I is triggered, read our companion piece on Phase I ESA and ASTM E1527-21 requirements. This article is for the grant manager who already has the award letter and now has to scope the work, pick a qualified firm, and keep every invoice eligible.

Here is what to require, in the order the questions come up.

Does an EPA Brownfields grant require a Phase I ESA?

For assessment work, effectively yes. Every Phase I conducted with EPA Brownfields Assessment Grant funds must comply with the All Appropriate Inquiries Final Rule at 40 CFR Part 312. An AAI-compliant assessment is an eligible use of your grant funds, and it is the documentary basis for the CERCLA liability protections the Brownfields program exists to support.

In practice, the Phase I is the front door of almost every grant-funded assessment project. You are not buying a Phase I because EPA mandates one form for one site; you are buying it because it is the only way to spend assessment dollars on a property while preserving your liability defense. The grant pays for the assessment, the assessment establishes the defense, and the defense is what makes redevelopment of a once-contaminated parcel possible without inheriting the cleanup bill. Skip it, or do it wrong, and the chain breaks.

What Phase I standard satisfies All Appropriate Inquiries in 2026?

ASTM E1527-21 is the current standard EPA recognizes as satisfying AAI under 40 CFR Part 312, with ASTM E2247-23 applying to forest land and rural property. E1527-21 became usable to satisfy AAI on February 13, 2023, per EPA’s final rule published in the Federal Register on December 15, 2022.

What this means for your scope of work: write the standard into the contract. The scope should state plainly that the Phase I will be performed to ASTM E1527-21 and will satisfy AAI under 40 CFR Part 312. Do not leave it to the firm to assume. A scope that names the standard up front gives you a clean basis to reject a deliverable that does not meet it, and it tells every bidder you know what you are buying.

Can I still use an old ASTM E1527-13 Phase I report?

No — not to satisfy AAI for a grant-funded acquisition. EPA ended its acceptance of ASTM E1527-13 on February 13, 2024, as set out in the same December 15, 2022 Federal Register rule. A Phase I performed today under the retired E1527-13 standard does not establish your liability defense and puts the expenditure at risk.

This is the single most common procurement trap. A firm may have an older report on the shelf from a prior look at the property, or a bidder may quote work to a standard they have not updated. If a consultant hands you a deliverable referencing E1527-13, do not accept it for grant purposes. The fix is not subtle: the assessment has to be done to the current standard. Watch for it in two places — the proposal’s stated methodology and the final report’s certification language.

What is the All Appropriate Inquiries (AAI) rule?

AAI is EPA’s standard at 40 CFR Part 312 for the environmental due diligence a buyer must perform to claim the CERCLA landowner liability protections — the innocent landowner, contiguous property owner, and bona fide prospective purchaser defenses under CERCLA § 101(35)(B). A Phase I performed to ASTM E1527-21 satisfies AAI.

Think of AAI as the rulebook and the Phase I as the work product that follows it. The rule defines who has to do the inquiry (an Environmental Professional), what they have to look at (records, the site, interviews, and historical use), and how recent that work has to be. For Brownfields grant recipients specifically, the same liability protection extends to assessments performed under CERCLA § 104(k), the section that authorizes the Brownfields program. The grant funding and the liability protection are wired together through this rule.

How much money does an EPA Brownfields Assessment Grant provide?

Assessment Grant applicants may request up to $1,000,000, with a performance period of up to 5 years, per EPA’s FY 2026 grant competition. In FY 2026, EPA selected 193 awards across 190 communities, totaling more than $248 million for Multipurpose, Assessment, and Cleanup grants, announced in EPA’s FY 2026 selections.

That five-year clock and the dollar ceiling shape how you sequence work. A $1,000,000 assessment grant has to cover Phase I work, Phase II site characterization where warranted, planning, and community involvement — and it has to be spent inside the performance period. The implication for procurement is that you want a firm that can scope efficiently and move on the timeline you actually have, not one that treats each Phase I as a standalone 40-billable-hour research project. Across a portfolio of sites, the difference in how fast and how cleanly a firm turns Phase I reports determines how much of the grant is left for the assessments that actually surface contamination.

How long is a Phase I ESA valid for a grant-funded acquisition?

AAI components generally must be conducted or updated within one year before the date of acquisition. Four key elements — the records review, the site reconnaissance, the interviews, and the Environmental Professional’s declaration — must be conducted or updated within 180 days of acquisition, under 40 CFR Part 312.

This is the detail the award letter never mentions, and it sinks more grant timelines than any other single factor. A Phase I ordered at the start of a long acquisition process can age out before you close. When that happens, the 180-day components have to be refreshed, which costs time and money you may not have budgeted. The discipline is to sequence the Phase I against the closing date, not against the day the grant funds hit your account. Order it too early and you pay to update it; order it too late and it does not arrive before the deal needs to close. There is a window, and a firm that has run this clock across many grant-funded acquisitions will help you hit it.

Who can perform a Phase I ESA for a Brownfields grantee?

The assessment must be performed by, or under the responsible charge of, an Environmental Professional (EP) who meets the 40 CFR Part 312 definition — a specific combination of credentials, education, and relevant full-time experience. You should document the EP’s qualifications in the assessment file.

Do not treat this as a formality. The EP definition is part of what AAI requires, and an assessment performed by someone who does not meet it is an assessment that does not satisfy AAI — regardless of how thorough it looks. When you evaluate proposals, ask for the named EP’s credentials and confirm they meet the Part 312 standard (a licensed professional with relevant experience, or a degree plus a defined number of years in the field, or the equivalent long-tenure path). Then keep that documentation in the file. If grant oversight ever asks why this person’s opinion supports your liability defense, the answer needs to be in writing, not in someone’s memory.

What does a Brownfields grantee do after the Phase I ESA?

It depends on what the Phase I finds. If the assessment identifies recognized environmental conditions (RECs), you typically scope a Phase II ESA — the sampling and laboratory analysis that characterizes the contamination — which is also an eligible grant use, under EPA’s programmatic requirements for Brownfield grants. If the Phase I finds no RECs, the AAI-compliant Phase I supports the acquisition and your landowner liability defenses, and there is no automatic obligation to go further.

That last point is worth holding onto, because it cuts against a common instinct. A clean Phase I does not require a Phase II “to be safe.” More on that below — over-scoping is one of the few ways a disciplined grantee can still waste limited grant dollars. The right sequence is: do the Phase I correctly, let its findings drive the Phase II decision, and keep the unspent assessment budget available for the sites that actually need characterization.

Does a Phase I ESA protect a grantee from CERCLA liability?

An AAI-compliant Phase I is a prerequisite for the CERCLA landowner liability protections, and Brownfields grant recipients using ASTM E1527-21 receive that protection under CERCLA § 104(k). But the Phase I alone is necessary, not sufficient — the defenses also require meeting continuing obligations after you take ownership.

This is the part that separates grantees who keep their protection from grantees who think they have it. The innocent landowner and bona fide prospective purchaser defenses do not vest at closing and stay locked in. They require ongoing conduct: taking reasonable steps to stop continuing releases, complying with land use restrictions and institutional controls, not impeding response actions, and providing legally required notices. A grantee who buys a property on the strength of a clean Phase I and then ignores those duties can lose the very defense the assessment was meant to establish. The Phase I opens the door. Staying through it is the continuing-obligations work, and it belongs in your post-acquisition plan, not in a drawer with the report.

What are eligible uses of EPA Brownfields Assessment Grant funds?

Eligible activities include AAI-compliant Phase I ESAs, Phase II site characterization, quality-assurance work, cleanup planning, and community involvement, performed within the grant’s terms and performance period, per EPA’s programmatic requirements for Brownfield grants. AAI compliance under 40 CFR Part 312 is specifically called out as an eligible use.

The practical translation is to tie every invoice to AAI-compliant scope. The assessment work is eligible only if it is performed to the rule — so a Phase I that fails AAI is not just a weak report, it is a potentially disallowed cost. Keep the paper trail tight: the scope of work names E1527-21 and Part 312, the report meets that standard, the EP’s qualifications are documented, and each invoice maps to eligible activity. That documentation is what turns “we spent the grant correctly” from an assertion into a defensible record.

The Three Procurement Mistakes That Cost Grantees the Most

Most of the risk in grant-funded assessment is not in the science. It is in the procurement decisions a non-specialist has to make under a deadline. Three traps account for most of the damage.

Accepting a stale or wrong-standard report. An E1527-13 deliverable, or a Phase I whose 180-day components have expired before closing, does not satisfy AAI. Confirm the standard in the scope and the report, and watch the shelf-life clock.

Hiring an unqualified EP. If the named Environmental Professional does not meet the 40 CFR Part 312 definition, the assessment does not satisfy AAI no matter how it reads. Verify credentials before award and document them in the file.

Over-buying when there is nothing to find. A Phase I that identifies no RECs does not obligate a Phase II. Scoping a Phase II “just in case” can burn limited grant dollars that the next site genuinely needs. Let the findings drive the next step, and consider whether a recent, qualifying assessment can be updated within the AAI windows rather than redone from scratch — the update path can avoid redundant spend.

None of this contradicts the core requirement. The AAI-compliant Phase I to ASTM E1527-21 is not optional for grant-funded assessment work. The discipline is to do it correctly and on schedule, and not to over-buy around it.

A Note on State Programs

The AAI rule and ASTM E1527-21 are federal standards that apply uniformly to EPA Brownfields grant-funded work nationwide, so the core requirement does not vary by state. Where states differ is in their voluntary cleanup programs (VCPs) and state Brownfields programs, which may add documentation or sign-off steps, and in state-specific expectations around conditions like vapor intrusion. In our region — Kansas, Oklahoma, Texas, Missouri, and Nebraska — grantees should confirm whether enrollment in a state VCP is expected alongside the federally funded assessment. The federal AAI and E1527-21 requirements apply regardless.

How iSi Supports Brownfields Grantees

iSi provides AAI-compliant Phase I ESA support for Brownfields grant recipients across our 40-state footprint — every assessment performed to ASTM E1527-21, under the responsible charge of a qualified Environmental Professional, with the standard and the EP’s credentials documented in the file from the start. When a Phase I identifies recognized environmental conditions, the same professionals handle the Phase II site characterization directly, so there is no gap between the assessment and the investigation and no second procurement to run against your grant timeline.

If you have a Brownfields award and a site list to assess, the next step is a scope-of-work conversation that gets the standard, the EP qualifications, and the shelf-life clock right before any work starts.
