| # Data Dictionary |
|
|
| Every field actually present in `US_Industrial_Facilities.csv` / `US_Industrial_Facilities.xlsx` (FACILITIES sheet). No field is included unless it is genuinely populated from EPA's own data. |
|
|
| | Field | Type | May be empty | Description | |
| |---|---|---|---| |
| | `facility_name` | string | No | Name of the industrial facility as registered with EPA TRI. | |
| | `operator` | string | No | Company/operator of record (parent company when reported, otherwise the facility's own registered name). | |
| | `facility_type` | string | No | Program classification. All records in this dataset are TRI-regulated facilities (Toxics Release Inventory). | |
| | `industry_activity` | string | No | General activity note: the facility manufactures, processes, or uses EPA-listed toxic chemicals above federal reporting thresholds. EPA's TRI facility endpoint does not expose a per-facility NAICS/SIC code, so none is fabricated here -- this field is a general program-level description, not a specific industry code. | |
| | `state` | string | No | US state, 2-letter abbreviation. | |
| | `city` | string | No | City where the facility is located. | |
| | `address` | string | No | Street address of the facility. | |
| | `source` | string | No | Always `EPA TRI (Toxics Release Inventory), data.epa.gov Envirofacts`. | |
| | `source_id` | string | No | EPA's own TRI facility identifier for this record -- use this to cross-reference back to EPA's own public systems. | |
| | `freshness` | string | No | Snapshot date and source-check note for this dataset (see README/QUICK_START for the exact date). | |
| |
| ## Fields intentionally NOT included |
| |
| - **Any person-level contact information** (name, email, phone) -- this product is a facility/company intelligence dataset, not a contact or mailing list. No individual-level contact data is included in this edition, by design. |
| - **Role/title of any contact** -- not applicable, since no contact data is included. |
| - **Any industry classification code (NAICS/SIC)** -- not exposed by the specific EPA TRI endpoint this dataset is built from, so none is invented. |
| - **Any purchase-intent, buying-signal, or "sales-ready" scoring** -- this dataset contains no such field. Any classification present is a factual, deterministic description of the facility's registered activity, never an inference about buying behavior. |
