EPA TSCA Inventory CASRN Activity Status Portfolio Event Monitor

Watch a book of CASRNs and emit typed Inventory events when the official EPA non-CBI TSCA Inventory CSV shows a substance flipping ACTIVITY ACTIVE↔INACTIVE, changing material FLAG values, appearing, or dropping from the published non-CBI list.

Not TRI facility twin (#31). Not Safer Choice product twin (#37). Not TSCA CDR site screener twin. Not REACH SVHC delta twin. Not a nationwide Inventory dump billed as rows.

Coverage honesty (CASRN exact match + non-CBI Inventory only)

Source: Official EPA non-CBI TSCA Inventory CSV zip
https://www.epa.gov/system/files/other-files/2026-05/csv-non-cbi-tsca-inventory.zip
→ TSCAINV_*.csv (fields: durable CASRN, ACTIVITY, FLAG, ChemName, UID).
Page: https://www.epa.gov/tsca-inventory/how-access-tsca-inventory
Keys: CASRN exact match after normalize (dashed form). Optional accession ACCNO / PMNACC is secondary documentation only — default SKU is CASRN on TSCAINV_*.
Cadence: EPA biannual Inventory refresh (plus interim if EPA posts a new zip).
Scope: Published non-CBI Inventory ACTIVITY/FLAG only — do not claim Master Inventory (CBI) coverage, ChemView dockets, or CDR site-level manufacture volumes.

Events

Event	When
`ACTIVITY_ACTIVE`	Watched CASRN ACTIVITY → ACTIVE
`ACTIVITY_INACTIVE`	Watched CASRN ACTIVITY → INACTIVE
`FLAG_CHANGED`	`FLAG` cell changed while still present
`APPEARED`	Watched CASRN missing → present on non-CBI Inventory
`DROPPED`	Watched CASRN present → missing from non-CBI Inventory
`RUN_STATUS`	Non-billable health row every successful run

First observation of a CASRN stores a baseline only (no product charge).

Modes

sourceMode=fixture (default): Store health / CI. With emitFixtureDemoEvents=false (default) emits only RUN_STATUS / FIXTURE_HEALTH → 0 product charges.
sourceMode=live: Official EPA Inventory CSV zip (no API key). One zip pull, extract TSCAINV_*.csv, in-memory filter to the watchlist — does not bill national rows.
