Nobody failed to find the asbestos
In June 2025 the School District of Philadelphia became the first school district in the United States to be criminally charged with environmental violations: seven counts of failing to conduct three-year re-inspections on time, and one of failing to perform six-month surveillance. Two months earlier the New York City Comptroller reported that of 1,431 schools known to contain asbestos, 18% had received the required triennial inspection and 22% the six-month surveillance, and recorded that the Department of Education kept no centralised recordkeeping system with reporting features.
Read those two findings together and the pattern is clear. These are not survey failures. They are proof-of-record failures. The work may well have been done; what could not be produced was the evidence that it had been.
Three regimes, kept deliberately apart
AHERA, NESHAP and New York’s ICR 56 use overlapping words to mean different things, on different clocks. Applying one regime’s number to another is the characteristic failure of every spreadsheet doing this work today, so the platform refuses to share a value between them:
- AHERA — 40 CFR 763 Subpart E. Homogeneous areas, the seven assessment categories of §763.88(b) as single-select with a mandatory written reason, minimum sample counts by material type and area, three-year re-inspection and six-month surveillance.
- NESHAP — 40 CFR 61.145. Notification is due ten working days before the work starts.
- New York ICR 56 — 12 NYCRR 56. Notification is due ten calendar days. For a Monday start those two rules are four days apart, and the platform computes each on its own calendar rather than approximating one from the other.
The details that decide the outcome
- The one-percent rule is strictly greater than. A result of exactly 1% is not asbestos-containing material. Rounding it up would be wrong and rounding it down silently would be worse; the platform holds the line and shows the value.
- No samples means not cleared. An area with no bulk samples is neither positive nor negative. It is unsampled, and it is displayed that way rather than defaulting to clean.
- Minimum sample counts, where the regulation prescribes one. Surfacing material by area, thermal system insulation, and the small-patch case. Where the regulation prescribes no count — miscellaneous material, non-friable suspect material — the platform says so rather than inventing a number.
- The retention clock does not start early. Records are kept indefinitely while any asbestos-containing building material remains; only once the last of it is gone does the clock run from the next re-inspection date.
The honest limit, stated on the page
The legally load-bearing artefact in this domain is a bulk sample in a bag with a paper chain of custody to an accredited laboratory. Hashing a photograph secures a picture about the material, not the material itself. So the platform models the sample as the primary object with the imagery hanging off it, which is the only arrangement that puts the tamper-evidence on the critical path rather than beside it.
And it is worth saying plainly, because you will not hear it from a vendor selling you a chain-of-custody feature: no federal or New York regulation prescribes the contents of a chain-of-custody record for asbestos bulk samples. The fields we capture are derived from the sampling record required by §763.85 and the recordkeeping of §763.94, plus ordinary accredited-laboratory practice. They are labelled in the product as derived, and we do not present them as a regulatory requirement.
Who this is for
The buyer is the consultancy that surveys before demolition, renovation, remodelling and repair — in New York, under ICR 56, with no square-footage floor to hide behind — and bills per survey. The volume is high, the margin depends on turnaround, and the liability sits with whoever can produce the file three years later.
