# DOCUMENT REGISTER — John P. Frawley dossier

Every artifact located in this investigation, with type, date, source archive, stable
locator, any Bates/exhibit number, seal status, and whether full text was obtained.
**Rule observed:** every entry has a real, resolvable locator; no IDs are invented.
"Located" = a resolvable locator exists. "Full text obtained" = the document body
(not just metadata/snippet) was actually read by a research agent.

Grading key: **[P]** primary obtained/read · **[P-cite]** primary, locator confirmed but body not read ·
**[2]** secondary · **[abs]** searched, not found.

| **DOC A** | Letter, **Frawley → V.K. Rowe (Dow)** re USDA Dr. John Leary's request to test phenoxy herbicides; hazards said to relate to 2,4-D not 2,4,5-T | **3 Jul 1963** | **[P-cite] — concrete exhibit locator FOUND (2026-06-09).** Indexed as exhibit **H281 14-1 5**, "john p. frawley's letter to V. K. rowe of 07-03-63" (parties: J.P. Frawley / Rowe, V.K. & Hunt, W.H.) inside a **local MDL-381 deposition/exhibit packet** — `toxicdocs/3unclear__xxxx__na__Dioxin__RBqNnvVrnkZ54xyyyqd9OyKV.txt` (lines 57656–57680; ToxicDocs `RBqNnvVrnkZ54xyyyqd9OyKV`). The H281-series **scan itself** still to be pulled; this is the first production handle ever located. (Court paraphrase remains 565 F. Supp. at 1273.) | ToxicDocs `RBqNnvVr…`; exhibit code **H281 14-1 5** |
| **DOC B** | **12 Jul 1965 confidential J.P. Frawley / Hercules Powder Co. memo**, recording a **9 Jul 1965 telephone conversation with Earl Farnham (Dow)**: Farnham convinced no other producer had removed the contaminant; **"Dow was extremely frightened that this situation might explode"**; competitors marketing 2,4,5-T with "alarming amounts of acnegen"; "the whole industry will suffer"; "particularly fearful of a congressional investigation." | **12 Jul 1965** | **[CONFIRMED-primary] (content) — UPGRADED from [P-cite] (2026-06-13).** Verbatim text + exact date/author/subject recovered from a **litigation brief** (Agent Orange MDL plaintiffs' brief), local `toxicdocs/3unclear__xxxx__na__Dioxin__jyBDvYGzG58gkKk3VmDbjxLK5.txt` (l.14017–14038) — **not** merely the U.S. Veteran Dispatch popular account. **Independently** logged in Dow's own *DOW DATA — Privileged & Confidential* index (DocumentCloud `3418806`, p.19; **index READ 2026-06-13**) as Bates **A303 / 650712**, in Dow's own words ("extremely frightened…", "particularly fearful of a Congressional investigation"), pointing to a "**better copy at p. B18977**." Content is thus **doubly attested** (plaintiffs' brief + Dow privilege log); the legible **B18977** page-image is the remaining target. **Note:** the "rabbit-liver study" detail in the old secondary account does **NOT** appear → confirms the earlier conflation suspicion.

| G1 | ~~ToxicDocs holds nothing on this Frawley~~ **— CORRECTED (this earlier finding was WRONG).** ToxicDocs' **native search API** reports **251 documents** matching "Frawley" and **39 matching the exact phrase "John P. Frawley,"** overwhelmingly in the **Allied Signal / Society of the Plastics Industry vinyl-chloride (PVC) collection, 1958–1970** (plus a dioxin cluster). The earlier "nothing" conclusion relied on Google's *incomplete* `site:` index. **Whether these are the Hercules toxicologist (topically likely — PVC = food-packaging = his domain; SPI = the threshold-of-regulation petitioner) or a namesake is UNCONFIRMED:** the scans are **image-only (JBIG2)** and could not be OCR'd from this environment (WebFetch can't read them; `/api/document` 404s; Bash is sandboxed). **Highest-priority open lead — see `05_OPEN_QUESTIONS` A0.** | toxicDocs `/api/search?q=Frawley` (251), `?q="John P. Frawley"` (39); cdn PDFs image-only |
| G2 | **Document A (1963 letter) not digitized anywhere** searched (Poison Papers, ToxicDocs, UCSF IDL, USDA NAL, DocumentCloud full-text API). | DocumentCloud API `q="V.K. Rowe" Frawley` → only the 1965 B 1575 letter |
| G3 | **No evidence Frawley ever testified before Congress.** Dingell Aug 1967 witness = **Goddard** (not Frawley); Frawley **absent** from the read 1970 Senate 2,4,5-T witness index. | Heckman first-hand account; Cong. Rec. Daily Digest D406 (10 Aug 1967); NAL full-text of the 1970 hearing |

## H. Lateral / numerology-lineage primaries — "the heirs of the round number" (added 2026-06-11)

*Held primaries for the five lateral threads that carry the *numerology of toxicology* past Frawley:
the **10⁻⁶ carcinogen-side de minimis**, **Bruce Ames**, the **RfD uncertainty-factor tower**, **GRAS
self-certification**, and **TLVs**. Catalog + retrieval routes in `papers/lateral/_LIBRARY.md`; paywalled
remainder in `papers/lateral/_WISHLIST.md`; analysis in `06_ANALYTIC_MEMO §Part 5` and (for the 10⁻⁶ /
DES-SOM seam) `10_DE_MINIMIS_LEGAL_LINEAGE §3.5`. Obtained open-access/government routes only — no shadow

Key chapters: **ch. 11, Charles Meinhold, "The NCRP Considerations on Levels of Negligible Risk"** — radiation NIRL = "**10⁻⁷ per year… trivial and negligible**"; "annual risk… increments of 10⁻⁷ or less, or total lifetime risks between 10⁻⁵ and 10⁻⁶… reasonably negligible"; 1 mrem/yr; NRC's 0.001 rem/yr cutoff "selected" "**following consideration of lower and higher numbers**." **ch. 8, Flamm, Lake, Lorentzen, Rulis, Schwartz & Troxell, "Carcinogenic Potencies and Establishment of a Threshold of Regulation for Food Contact Substances"** — the chemical 10⁻⁶ machinery via a carcinogen-potency distribution (**1987 precursor to Rulis 1992, H13**, and the 1995 ToR rule). **ch. 6, Travis & Richter, "On Defining a De Minimis Risk Level for Carcinogens."** Volume juxtaposes the numbers ("FDA interprets its 10⁻⁶ criterion cautiously"; UK NRPB 10⁻⁶/yr "modified by a factor of 100" to a lifetime basis). **ch. 6 close-read:** de minimis carcinogen level "**varies from 10⁻⁴ to 10⁻⁶ depending on the size of the population impact**" (background-SD method → ~10⁻⁴; 10⁻⁶ only as the whole-U.S.-population floor) — the de-minimis-*level* companion to Travis et al. 1987 (H24). **ch. 8 close-read:** Gaussian potency distribution (343 carcinogens) + low-dose linearity → 1 ppt cutoff "excludes almost all risks of 10⁻⁶"; "**any risk level could be chosen**"; **Reference 1 = *Monsanto v.

The key contrast: ICRP/IAEA principles are "**very difficult to apply in the USSR because the concepts of risk and acceptable risk are rejected categorically**" — Soviet threshold-based "socialist hygiene." **The irony:** rejecting acceptable risk did *not* yield a stricter number — 350 mSv ≈ **10⁻⁴/yr (1.7×10⁻² lifetime)**, ~1000× the NCRP public-negligible 10⁻⁷/yr (H34) and ~10⁴× the FDA 10⁻⁶ (H25). **Absolutism in rhetoric ≠ stringency in practice** — a third pole beside Delaney (absolute statute) and the calculated threshold. **Operator Taildrop 2026-06-13.** | 1991 | local PDF | `papers/lateral/healthphysics1991_filyushkin_350mSv_soviet.pdf/.txt`; excerpt `sources/Filyushkin1991_soviet-350mSv_acceptable-risk-rejected_excerpt.md` | **[P] yes** (read in full) |
