Tier II Reporting Thresholds by State
Federal EPCRA sets the Tier II trigger at 10,000 pounds for a hazardous chemical that needs a safety data sheet, and 500 pounds or the Threshold Planning Quantity, whichever is lower, for an Extremely Hazardous Substance. Most states use those numbers. EPA lets states go further, and some do — so a facility that would never file in Texas or Ohio can be a reporter in Vermont or Delaware with a few drums on site.
These are the states in our state-by-state guides where reporting can start below the federal thresholds, or where the state adds its own trigger. Each summary restates our state guide, which quotes the state agency, statute or rule; follow the state link for sources, filing steps and fees.
States with lower or additional Tier II thresholds
| State | Where reporting starts | Details |
|---|---|---|
| Vermont | 100 pounds (or the TPQ, if lower) | Vermont Table I sets 100 pounds or the Threshold Planning Quantity, whichever is lower, for Extremely Hazardous Substances and other hazardous chemicals that need a safety data sheet. Petroleum products and fuels report at 10,000 pounds, and known human carcinogens and licensed explosives at any amount. Consumable products in containers of 40 pounds or less are not reportable. |
| Delaware | 55 gallons or 500 pounds | DNREC lists hazardous chemicals as potentially reportable at 55 gallons or 500 pounds, whichever is lower, and Extremely Hazardous Substances at 55 gallons, 500 pounds or the Threshold Planning Quantity, whichever is lower. Some substances may have a higher threshold. |
| Louisiana | 500 pounds | The Louisiana State Police Right-to-Know summary sets the state threshold at 500 pounds of a chemical present on site on any one day during the preceding calendar year, with lower thresholds for some Extremely Hazardous Substances. |
| California | 55 gallons, 500 pounds or 200 cubic feet (HMBP) | California's Hazardous Materials Business Plan applies under Health and Safety Code section 25507 when a business handles a hazardous material at or above 55 gallons of a liquid, 500 pounds of a solid or 200 cubic feet of compressed gas, filed in CERS with the local CUPA. |
| Oregon | 500 gallons, 500 pounds or 500 cubic feet | The Oregon State Fire Marshal's reportable quantities are 500 gallons for liquids, 500 pounds for solids and 500 cubic feet for gases stored for more than 24 hours; 5 gallons, 10 pounds or 20 cubic feet for highly toxic substances and explosives; any amount of radioactive material; and the federal Threshold Planning Quantity or 500 pounds, whichever is less, for Extremely Hazardous Substances. Any substance requiring an SDS under Oregon-OSHA counts. |
| Alaska | Any quantity for certain hazard classes | Alaska DEC lists stricter thresholds under Alaska Statute 29.35.500(c): any quantity of materials in federal placarding classes 2.3 and 6.1 poisons, explosives 1.1 to 1.3 (with exclusions), flammable solids 4.1 to 4.3 and radioactive class 7; 1,000 cubic feet of compressed gases; 500 pounds or the TPQ for Extremely Hazardous Substances; and 10,000 pounds for other hazardous chemicals. DEC's table lists chlorine as reportable in any amount. |
| Nevada | International Fire Code quantities (Fire Marshal) | Nevada keeps the federal thresholds for the SERC, but the State Fire Marshal also requires reporting and a permit for all chemicals in the quantities listed in the International Fire Code, 2024 Edition, including all gas stations. |
| New Jersey | Covered industries report every year; batteries at 500 pounds | New Jersey applies the federal thresholds plus its Worker and Community Right to Know Act: facilities in a covered NAICS code must respond to NJDEP every year even with nothing to report, and lead or sulfuric acid in forklift, pallet-jack and backup-power batteries is reportable at 500 pounds for covered facilities. |
| Hawaii | Zero, when an agency asks | Hawaii uses the federal thresholds for the annual report, but the minimum threshold for reporting in response to a request from the SERC, LEPC or fire department with jurisdiction is zero. |
What this means for a small facility
At 10,000 pounds, a clinic, shop or shelter rarely reports. At 100 or 500 pounds it often does: a pallet of pool chemicals, a few drums of cleaning concentrate, a propane cylinder bank, forklift batteries or a diesel tank can each cross the line. Count the maximum amount of each product on site at any one time, compare it with your state's number, and remember that fees are set separately — see Tier II fees by state. For the federal basics, see EPCRA Tier II Reporting: Does Your Facility Need to File?
Every other state we cover uses the federal thresholds for the annual Tier II report, though some add other layers such as state fees, site plans or extra forms. Thresholds change; confirm with your state before you rely on a number.
Tier II is an EPA (EPCRA) program. Workplace hazard communication is a separate OSHA rule, and in State Plan states the 2024 HazCom update arrives on each state’s own timeline: see 2024 HazCom update status by State Plan.
Frequently asked questions
What are the federal Tier II thresholds?
Under federal EPCRA, a facility reports a hazardous chemical that requires a safety data sheet when 10,000 pounds or more is present at any one time, and an Extremely Hazardous Substance at 500 pounds or its Threshold Planning Quantity, whichever is lower. States may add chemicals and set lower thresholds.
Which states have lower Tier II thresholds than federal law?
Among the state programs we have documented, Vermont (100 pounds), Delaware (55 gallons or 500 pounds), Louisiana (500 pounds), California's HMBP (55 gallons, 500 pounds or 200 cubic feet), Oregon (500 gallons, pounds or cubic feet), Alaska (any quantity for certain hazard classes) and Nevada (International Fire Code quantities for the State Fire Marshal) require reporting below the federal thresholds. New Jersey and Hawaii add their own triggers.
Which state has the lowest Tier II threshold?
Several states require reporting of some materials in any amount: Vermont for known human carcinogens and licensed explosives, Oregon for radioactive material, and Alaska for certain placarded hazard classes and chlorine. For ordinary hazardous chemicals, Vermont's 100 pounds is the lowest general threshold we have documented.
Most SDS software stops at the safety data sheets. OSHA HazCom asks an employer for five things: a written program, a chemical list, container labels, SDS access and employee training. SDSentry covers all five in one product and builds the written program from your own chemical list. See how 11 SDS tools compare on all five →
SDSentry keeps your SDS library, GHS labels and HazCom training records in one place — OSHA deadline price: $24 per location a month, or $199 a year (regularly $49). Start by November 20, 2026 to lock it in.
Unlimited users and no SDS cap. On an annual plan that is less than any paid SDS tool we compared.
