  Illinois IEMA-OHS (SERC), Tier II reporting page, read 2026-09-05 and 2026-09-10: the page states who must file — “Owners or operators of facilities with hazardous chemicals on hand in quantities equal to or greater than set threshold levels must submit Tier II forms between January 1 and March 1 for the previous calendar year” — and does not restate any pound threshold of its own; it links to the federal Appendix A to Part 355. We read the agency page, not 430 ILCS 100 itself, so we grade this as guidance rather than codified.

  Indiana Code 13-25-2-10.4, published in full by the Indiana Emergency Response Commission, read 2026-09-09. The statute keys its fee tiers to the federal thresholds rather than setting Indiana ones: “A fee of one hundred dollars ($100) for a facility in which … one (1) or more hazardous chemicals were present in amounts exceeding the threshold quantities established under 42 U.S.C. 11022(b)”. This is Indiana’s own statute pointing at the federal number, which is why we grade it codified — but it is the fee section, not a separate reporting-threshold section. We found no Indiana provision setting a different threshold.

  Kentucky, 106 KAR 1:081 (apps.legislature.ky.gov, read directly 2026-09-10). Section 2(3)(a): “The minimum reporting thresholds shall be as established at 40 C.F.R.” — the regulation adopts the federal numbers by reference rather than setting Kentucky ones. Section 2(3)(b) does the same for exemptions: “The EPCRA chemical exemptions shall be those exemptions established in 40 C.F.R.” Fees sit in Section 3(1): “There shall not be a fee for a Category One Facility”; “The fee for a Category Two Facility shall be forty (40) dollars”; “The fee for a Category Three Facility shall be $250.” Categories Four and Five are also $250, and Category Five is “any facility that has an Extremely Hazardous Substance (EHS)” — which catches most Tier II filers.

  Michigan EGLE, “Michigan Facilities’ Guide to SARA Title III” Rev. 12/2023 (michigan.gov/egle), read in full 2026-09-11. On thresholds it uses the federal numbers and nothing else: its own decision flowchart asks “Is the chemical on site in an amount equal to or greater than 10,000 pounds?” and “Is the EHS ever on site in an amount equal to or greater than 500 pounds?”, and the guide restates 40 CFR Part 370 throughout without naming a Michigan figure. What it adds is a separate programme: “The Michigan Fire Prevention Code, Public Act 207, requires that the owners and operators of facilities provide the fire department with the quantities and locations of chemicals specified by the fire chief. The data are used by the fire chief to develop a plan for the protection of the fire fighters. The chemicals that must be reported under Act 207 include all hazardous chemicals at the facility in amounts that might be of concern.” A second one sits under Part 31 of 1994 PA 451: facilities with a Pollution Incident Prevention Plan “must notify their LEPC within 30 days after its completion.” The guide names no Tier II filing fee anywhere in its 142 pages — that is a statement about the document, not proof that none exists.

The deck lists the thresholds outright and they are the federal ones: “Gasoline (all grades combined): Aboveground or Underground tanks at non-retail facilities - 10,000 pounds; Underground tanks holding fuel for retail sale to the public for motor vehicles on land - 75,000 gallons; Diesel (all grades combined): Aboveground or Underground tanks at non-retail facilities - 10,000 pounds; Underground tanks holding fuel for retail sale to the public for motor vehicles on land - 100,000 gallons; Other substances for which you are required by OSHA, to maintain a SDS 10,000 pounds; Extremely Hazardous Substances (EHS): 500 pounds (or the Threshold Planning Quantity (TPQ)).” On the TPQ it adds the federal rule in its own words: “Your TPQ is that number or 500 lbs, whichever is less.” The FAQ repeats the 10,000-pound figure for ordinary hazardous materials.

  Two documents the Commonwealth publishes itself, both read 2026-09-11. Its annual Tier II memo dated 6 January 2026: “Facilities covered by the reporting requirements of the federal Emergency Planning and Community Right-to-Know Act (EPCRA) must submit annual Tier II reports to the State Emergency Response Commission (SERC), the Local/Regional Emergency Planning Committee (LEPC/REPC), and the Local Fire Department. Tier II Reports for 2025 must be filed by March 1, 2026.” And the SERC’s own 13-page “Guide to EPCRA”, which sets out thresholds entirely in the federal terms — the EPA list of extremely hazardous substances and their threshold planning quantities — and names no Massachusetts figure. We looked for a state-specific number and did not find one; Massachusetts does have its own Right-to-Know law (M.G.L. c.111F), but that is workplace right-to-know, not a different section 312 threshold.

The TPQ of an EHS can be found on the EPA’s Consolidated List of Lists. For gasoline (all grades combined) at a retail gas station: the threshold level is 75,000 gallons (or approximately 283,900 liters), if the tank(s) was stored entirely underground and was in compliance at all times during the preceding calendar year with all applicable UST requirements at 40 CFR part 280 … For all other hazardous chemicals: the threshold level is 10,000 pounds.” Those are the federal figures and conditions, restated — we found no Kansas figure of its own.

Arizona keeps the federal numbers: “For above-ground storage tanks and non-retail USTs, the threshold level for reporting is 10,000 pounds. For gasoline at a retail gas station, the threshold level is 75,000 gallons (all grades combined).” What differs is local: “Facilities filing in the Town of Gilbert should be aware that Gilbert has its own Fire Department Regulation for reporting chemicals, and those reporting quantity triggers are much lower than what the State mandates as a Tier II chemical. Though these particular chemicals may not constitute a Tier II report, the Town of Gilbert Fire Department requires its facilities to use the Arizona Tier II Reporting System to manage these chemicals.”

We read the whole of chapter 299K (299K.01–299K.10) and found no Minnesota threshold of its own: the chapter designates additional facilities and sets fee rules (299K.09), and leaves the numbers to the federal act.

Under both section 311 and section 312: “Which facilities are covered? Any facility required to prepare or have available safety data sheets … under the federal OSHA hazard communication standard. In Minnesota, public sector facilities are also covered.” The thresholds it lists are the federal ones — 500 lb or the threshold planning quantity for an extremely hazardous substance, 10,000 lb for any other hazardous chemical, with the federal retail fuel allowances of 75,000 gallons of petrol and 100,000 of diesel.

New Jersey keeps its own Environmental Hazardous Substance list, wider than the federal one; we have not counted either list ourselves, so we do not put a number on “wider”. § 7:1G-2.1 designates six categories of environmental hazardous substance, pulling from the federal lists: “Toxic Chemicals on the list at 40 CFR 372.65”, “Extremely Hazardous Substances on the list at 40 CFR 355 Appendix A”, selected substances in the chapter’s own Appendix A, unusually hazardous substances (Saran, PVC and Lopac), substances subject to pollution prevention planning, and “Regulated Substances on the list at 40 CFR 68.130”. The quantity is in § 7:1G-3.1(b): “A threshold of 500 pounds or the Federal SARA 302 threshold planning quantity, whichever is lower, shall apply to all EHSs present in aggregate at the facility at any one time.” Read “in aggregate” carefully — the federal test is per substance, so New Jersey’s wording can catch a site that no single substance would catch. We have not confirmed how the department applies it, so we do not compute it. NJDEP, “Who Must Report” (nj.gov/dep/enforcement/opppc/crtk/who.html), read 2026-10-12 through the Internet Archive snapshot dated 2026-04-10 because the live site refuses our requests with HTTP 403: “New Jersey employers, whose businesses are assigned covered North American Industry Classification System (NAICS) codes listed in the New Jersey Worker and Community Right to Know regulations, are required to submit CRTK surveys listing the environmental hazardous substances (EHSs) present at their facilities in quantities that exceed 500 pounds, unless the EHS is on the federal … Section 302 list of extremely hazardous substances … with a lower reporting threshold.” NJDEP’s CRTK FAQ (revised 7/24/17, Internet Archive snapshot dated 2025-09-02) settles “aggregate”: toluene in a can, a drum and a jug that “together … exceed the reporting threshold” is reported, one entry per container type — so the amount is added up per substance across the site. On batteries: “If the aggregate amount of lead or sulfuric acid in the batteries in your forklifts, pallet jacks, and your backup power supply … meets or exceeds 500 pounds at your facility, then these substances must be reported on the CRTK Survey”; for a business with an uncovered NAICS code the lead threshold is 10,000 pounds, and “The batteries in automobiles and trucks are exempt from reporting.”

Alaska Department of Environmental Conservation, “Emergency Planning and Community Right-to-Know Act and State of Alaska Tier II Reporting” (dec.alaska.gov), read 2026-10-12 through the Internet Archive snapshot dated 2026-06-16 because the live page refuses our requests with HTTP 403. Under “Are there any Alaska-specific reporting requirements?” it says: “Several categories of chemicals have stricter reporting thresholds in Alaska than required by Federal regulation. The following substances and reporting thresholds are established in Alaska Statute 29.35.500(c)”, and lists the same classes. The statute’s own wording ties these numbers to municipal programmes; the department applies them to Tier II reporting in Alaska, so we follow the department — it is the stricter reading.

  Two separate duties in Rhode Island, and only one of them is Tier II. Tier II: the thresholds are the federal ones. US EPA’s “State Tier II Reporting Requirements and Procedures” records the submission route for Rhode Island and no state threshold below the federal 10,000 lb / 500 lb-or-TPQ tests. We could not reach DEM’s own Tier II page on 2026-09-07, so that part rests on EPA’s compilation. The separate annual registration, run by the Department of Labor and Training rather than DEM, on the state’s own page, read 2026-09-07: “In compliance with Rhode Island General Law, Section 28-21, employers must complete the Hazardous Substance Right-to-Know Annual Registration Form and submit it to the RI Department of Labor and Training, Right-to-Know Unit.” It applies “If you have at least one employee, full or part-time, and you have hazardous substances greater than 2 gallons or 10 pounds, or a product containing at least 1%” of a listed carcinogen. You are exempt where “Employees are not exposed to hazardous substances greater than 10 pounds or two gallons stored and/or used on the premises or any carcinogens.” On cost: “Although there is no longer a registration fee, you are still required by law to comply with all the requirements listed below.” R.I. Gen. Laws § 28-21-2 and § 28-21-3, read 2026-09-08 on the General Assembly’s own server. § 28-21-2 defines a “designated substance” as one on the chapter’s list “provided they are in quantities exceeding two gallons (2 gals.) or 10 pounds (10 lbs.).” § 28-21-3 requires the employer to “obtain and maintain chemical identification lists” giving “the common and trade names of all designated substances present in the workplace in alphabetical order, cross referenced to their chemical names,” with a far lower trigger for carcinogens, mutagens and teratogens.

Oklahoma DEQ, Tier II reporting page, says the same in its own words: extremely hazardous substances “over 500 lbs or the TPQ whichever is lower”; all other hazardous materials “over 10,000 lbs”; retail gasoline “over 75,000 gallons if stored underground”; diesel “over 100,000 gallons”.

  A secondary source lists Maryland as setting local thresholds. We could not find any Maryland rule that does, and the state’s own site refused our requests, so we treat Maryland as federal until we can read a Maryland rule that says otherwise.

Vermont Tier II package, “Conversion Factors (Gallons to Pounds)” (state agency table published with the official form)

Typical figures — check yours

Section 9 of your safety data sheet has the real number for your product. Where the strength of a solution matters, we refuse to convert rather than use a figure meant for a different strength.

⚠️ Vermont’s own form package tells you to use 9.00 pounds a gallon for a liquid you cannot find a figure for. We do not apply it for you — a made-up weight is worse than a question — but Vermont filers should know their state says it.

Read directly out of Tier2 Submit 2025 Rev 1 (resources/html/t2s_fields.js) on 2026-08-27 and compared character by character by our own check. The published sample file that ships with the data standard disagrees with the program on six of these, so we follow the program.

• Some states’ own thresholds

  We have read the threshold rules of 50 of the 52 places we cover (the states, DC and Puerto Rico) in full. For the other 2 (MD, NV) we apply the federal thresholds and say on the answer that this is what we did.

• How each state wants the file handed over

  We have read each state’s own page on how it wants the file handed in, and we still link that page, because states change them. Ohio, for one, has no upload page at all and wants a certification letter and a site map alongside the file.

• Which hazards apply to your specific product

  Manufacturers classify the same product differently. We fill in what a typical sheet says and ask you to correct it against yours, because you are the one signing.

• Whether next year’s software changes the wording

  EPA published a longer hazard list in May 2026 that the current program does not use. When the new version ships we compare our strings against it before anyone files.
