EPA Toxics Release Inventory (TRI) Data
BLS Producer Price Index - Telephone Apparatus Manufacturing (PCU334210334210)
Where the fields line up
No shared field names. These two answer different questions.
| Field | EPA Toxics Release Inventory Data | BLS Producer Price Index - Telephone Apparatus Manufacturing |
|---|---|---|
TRIFD | TRI facility identifier assigned to the reporting site - the join spine that stitches one plant's filings together across chemicals and reporting years. | not in this set |
FRS FACILITY ID | EPA Facility Registry Service identifier, cross-walking the same physical site across the agency's program systems - the bridge to permits, compliance histories and enforcement records. | not in this set |
RCRA / NPDES IDENTIFIERS | Hazardous-waste and discharge-permit program numbers attached to the facility where they apply, letting an environmental screen reach the same fence line from three regulatory directions. | not in this set |
FACILITY NAME | Name of the reporting facility as filed - the human-readable half of the row that turns a poundage ledger into a plant directory. | not in this set |
FACILITY CITY / COUNTY / STATE / ZIP | Facility location block down to street-level geography, sufficient for parcel matching, drive-time screening and county rollups without a geocoder. | not in this set |
LATITUDE / LONGITUDE | Facility coordinates drawn from EPA's Facility Registry Service, so every record drops onto a map and proximity analysis becomes a spatial join. | not in this set |
PRIMARY NAICS CODE | Six-digit North American Industry Classification System code of the facility's main activity; chemical manufacturing sits under NAICS 325 and legacy SIC codes ride alongside in older years. | not in this set |
PARENT COMPANY NAME | Parent company of the facility owner as reported - the first rollup path from plant-level disclosures to corporate portfolios. | not in this set |
STANDARDIZED PARENT COMPANY NAME | Agency-standardized parent company name carried beside the reported one, so subsidiary spellings collapse to actual owners instead of fragmenting corporate rollups. | not in this set |
REPORTING YEAR | Calendar year the submission covers - the axis every trend rides, running unbroken from 1987 through 2024. | not in this set |
CHEMICAL NAME | Name of the reported substance as listed on the TRI chemical list, with generic names standing in where a specific identity is claimed confidential. | not in this set |
CAS NUMBER | CAS Registry Number pinning substance identity - the join key across the inventories, release ledgers and property references in this catalog. | not in this set |

What each does better
EPA Toxics Release Inventory Data
Identity all the way down to the fence line. Every filing carries a TRI Facility ID joined to name, city, county, state, ZIP, latitude and longitude, plus FRS, RCRA and NPDES identifiers - and a parent company name standardized by EPA, so subsidiary rollups resolve to actual owners.
Chemical resolution to the register number. Substances arrive as TRI-listed chemical names with CAS numbers, units of measure (pounds, grams for dioxins) and a carcinogen classification flag. PFAS screens, metal-compound tallies or carcinogen-scoped studies resolve to exact substances, not baskets. See toxics release inventory for how these filings fit the wider environmental-reporting stack.
Route-split physical quantities. Fugitive and stack air emissions, surface water discharges with per-stream breakdowns, underground injection split by well class, on-site landfills split by RCRA Subtitle C status, off-site transfers, plus recycling, energy recovery and treatment quantities and source-reduction activities. The full waste-management mix behind one facility-year.
Thirty-eight reporting years deep. Annual filings run 1987 through 2024 in the current release set - an unbroken longitudinal spine, and one wide enough that a single national year spans roughly 282 columns across ten files.

Monthly cadence on a fixed base. Values publish month by month against a December 1985 equals 100 reference, not seasonally adjusted, with the current bulk history carrying observations back to January 1998. Where TRI moves annually, this series moves twelve times as often.
See implied deflator for the arithmetic.
Zero entity ambiguity. There is no facility roster to deduplicate, no company-name normalization, no chemical spelling variance. Eight fields, one value per month, ready for arithmetic the day it lands.
Where they're equivalent
On pedigree and plumbing more than on content. Both come from US federal statistical programs, both score 9 out of 10 against a catalog average of 7.81, and both field dictionaries were verified during research. Both cover the United States - TRI reaching states, territories and tribal lands, the PPI aggregating nationally.
Neither is wrong - both simply keep improving after first publication.
The verdict
Verdict: sample both, pick by fit - they are different instruments pointed at neighboring questions.
Take EPA Toxics Release Inventory (TRI) Data if your question names a place or a substance. Supplier screening, community exposure studies, compliance histories, parent-company footprint maps, whether specific plants are reducing or just relocating their waste - anything answered by named facilities, CAS-numbered chemicals and route-split poundage. Accept self-reported figures: quantities come from the filers themselves, and prior years can be restated.
Accept anonymity: no facility, company or product list rides behind any value, and recent months stay preliminary.
Sample both, pick by fit. See EPA Toxics Release Inventory Data · See BLS Producer Price Index - Telephone Apparatus Manufacturing
Or take both in one feed
Yes - as numerator and denominator of different halves of one question, though the join is analytical rather than keyed. A workable pattern: let TRI establish the physical exposure - which chemical suppliers concentrate releases, whose parent companies recur across sites - then bring the PPI underneath wherever those suppliers buy or build telecom-bearing equipment, converting nominal capital lines into real terms before comparing across years. A market researcher pricing a monitoring-system rollout gets the hardware deflator from the index and the siting constraints from the inventory; neither alone answers both.
Two alignments decide whether the combination holds. First, keys: there is no shared identifier between a facility filing and an index observation - NAICS adjacency is the bridge, and it is yours to argue. Second, periods: annual filings against monthly readings, so decide early whether you are averaging the index into reporting years or interpolating between them. Align geography last; one side resolves to addresses, the other refuses to go below the nation.

Fair questions
Do the two datasets cover the same ground?
Almost none. Both are United States federal records cut along NAICS manufacturing lines, but TRI names facilities, parent companies and CAS-numbered chemicals; the PPI series carries no site, company or substance - one index value per month. A pound of toluene is not a substitute for a point of index.
Which dataset reaches further back?
The BLS index reaches older at its base - December 1985, with the bulk history carrying monthly observations from January 1998 into July 2026.
Which should an ESG analyst studying a chemical supplier sample first?
Start with EPA TRI Data - the question names sites and substances, and only it answers with named plants, CAS-numbered chemicals and route-split poundage. Add the BLS index when pricing equipment or indexing contracts. Both arrive normalized to their documented field dictionaries.
Can Datadory deliver both datasets together?
Yes - alone or merged onto one calendar, delivered daily, weekly, or hourly - your call. Each arrives normalized to its documented field dictionary (twenty fields on the TRI side, eight on the PPI side) with sample rows before anything ships. The only joining work is NAICS alignment, handled in the merge. Or take both in one feed.
