EPCRA Tier II hazardous chemical inventory reporting thresholds by state
The quantity threshold at which a facility must file an annual Tier II hazardous chemical inventory report in each US state, compared to the federal EPCRA Section 312 baseline. Federal thresholds: ≥10,000 lbs for hazardous chemicals, ≥500 lbs or the threshold planning quantity (whichever is lower) for extremely hazardous substances (40 CFR Part 370). EPA authorizes states to set lower thresholds and add chemicals, and at least 9 states have done so: California (55 gal/500 lbs), Louisiana (500 lbs), Vermont (100 lbs — among the strictest), Delaware (55 gal/500 lbs), Oregon (dual-level system), Nevada (IFC-based, some categories at 0 lbs), Alaska (any quantity for certain hazard classes), New Jersey (own EHS list), and New York City (own EHS list with very low thresholds). Answers 'does my California facility need to file Tier II for 600 pounds of a hazardous chemical' (yes — California threshold is 500 lbs, below the federal 10,000), 'what is Nevada's reporting threshold for flammable materials', and 'which states have lower Tier II thresholds than federal'.

| State | General hazardous chemical threshold | EHS threshold | Special categories or chemicals | Filing deadline | Report name | Citation |
|---|---|---|---|---|---|---|
| Alaska | 10,000 pounds (federal threshold for non-placarded chemicals) | 500 pounds or the TPQ, whichever is lower (federal) | Poison Gas Hazard Division 2.3 and Poisons 6.1: any quantity; Explosives 1.1, 1.2 and 1.3 (excluding smokeless gunpowder, black powder, and ammunition): any quantity; Flammable Solid Divisions 4.1, 4.2 and 4.3: any quantity; Radioactive Hazard Class 7: any quantity; Compressed gas: ≥1,000 cubic feet | March 1 | ||
| Californiasources differ | 55 gallons (liquids), 500 pounds (solids), 200 cubic feet (compressed gasses) | 500 pounds or the TPQ, whichever is lower (federal) | Any quantity of hazardous waste | March 1 | Hazardous Materials Business Plan | |
| Colorado | 10,000 pounds (federal) | 500 pounds or the TPQ, whichever is lower (federal) | Requires use of Tier2 Submit; some LEPCs and fire departments may require additional reporting elements | March 1 | Tier II | |
| Connecticut | 10,000 pounds (federal) | 500 pounds or the TPQ, whichever is lower (federal) | Requires Tier II reports to be submitted directly to local fire departments, often with unique local formatting and mapping requirements | March 1 | Tier II | |
| Delaware | 55 gallons or 500 pounds, whichever is lower | Threshold Planning Quantity (TPQ) if lower than 55 gallons or 500 pounds | Chemicals used exclusively for heating the facility: 10,000-pound threshold | March 1 | ||
| Federal (baseline)sources differ | 10,000 pounds | 500 pounds or the Threshold Planning Quantity (TPQ), whichever is lower | Gasoline at retail gas station: 75,000 gallons (all grades combined, tank(s) entirely underground in UST compliance); Diesel fuel at retail gas station: 100,000 gallons (all grades combined, tank(s) entirely underground in UST compliance) | March 1 | Tier II | 40 CFR Part 370 |
| Florida | 10,000 pounds (federal) | 500 pounds or the TPQ, whichever is lower (federal) | Accepts Tier II reports through E-Plan; imposes additional requirements related to facility emergency contacts and notifications | March 1 | Tier II | |

| Louisianasources differ | 500 pounds | Threshold Planning Quantity (TPQ) if lower than 500 pounds | Used oil must also be reported | March 1 | ||
| Nevada | Determined using the International Fire Code List (IFC); thresholds range from 0 to 500 lbs depending on material type | Federal thresholds apply for chemicals not in IFC categories | Flammable materials to water-reactive materials have IFC-specific thresholds; no exemptions can be applied to IFC-category materials; if a chemical does not apply to an IFC category, federal Tier II thresholds and federal exemptions apply | March 1 | Community Right-to-Know Act | |
| Nevada (Clark County) | International Fire Code (IFC) thresholds, often triggering reporting at much lower quantities than the federal 10,000-pound standard | Submission functions as both an EPCRA report and a State Fire Marshal operating permit; dual reporting period; additional recordkeeping requirements and local hazardous materials fees | March 1 | |||
| New Jerseysources differ | State-specific EHS list determines chemical-specific reporting threshold | New Jersey has its own EHS list with chemical-specific thresholds | State EHS list is substantially larger than the federal list and includes solids deemed "unusually hazardous substances"; NAICS Code assessment required — facilities without a covered NAICS Code are exempt from reporting | March 1 | Community Right to Know Program | |
| New York | 10,000 pounds (federal) | 500 pounds or the TPQ, whichever is lower (federal) | State agencies accept Tier II reports via E-Plan | March 1 | Tier II | |
