Four States, One Deadline, Four Different Definitions of Submitted: Tier II Reporting in Kansas, Oklahoma, Missouri and Nebraska

Tier II filings across Kansas, Oklahoma, Missouri and Nebraska run on four incompatible state processes. What multi-site EHS managers must know before March 1.

Kansas Has No Submit Button, and KDHE Says So in All Caps

The Kansas Department of Health and Environment publishes a Tier II guidance document with a heading in capital letters: “WHERE IS THE SUBMIT BUTTON?” The answer underneath should reorganize how every multi-site EHS manager thinks about chemical inventory reporting across state lines.

“You are working directly on the web so there isn’t any one button that ‘submits’ the Tier II report… For your submission to be considered complete, you must generate and send the required paperwork (online certification letter fee calculation worksheets) with payment to the Right-to-Know Program.” (KDHE Tier II Reporting Information)

A safety manager keys every chemical into the Kansas portal, hits Update on every screen, sees no errors, and closes the browser. He has filed nothing. Kansas applies the same rule to facilities that owe no money at all: “Facilities that owe $0 fees may also submit their paperwork by email.”

That is one state. Add plants in Tulsa, Kansas City and Omaha and you are filing against a single federal statute through four systems that share no file format, no fee model, no credentialing method and no distribution rule. The federal layer is the easy part and the only part most published guidance covers. The four state layers are where February hurts.

Tier II is the annual hazardous chemical inventory required under EPCRA Section 312 (42 U.S.C. 11022) from any facility that keeps an OSHA Hazard Communication safety data sheet and holds a covered chemical above threshold; the applicability walkthrough is in Does the March 1 Deadline Apply to Your Facility?. This post covers what “filed” means in each of the four states.

Do I Have to File a Separate Tier II Report in Every State Where I Have a Facility?

Yes. EPA runs no federal Tier II portal. EPCRA Section 312 requires submission to the State Emergency Response Commission, the Local Emergency Planning Committee and the fire department in each facility’s own state (40 CFR Part 370), and every state built its own system. Four facilities in four states means four filings, four formats, four fee schedules and four sets of credentials.

Congress wrote that flexibility in on purpose. States may add chemicals, lower thresholds and build their own forms (75 FR 39825), and EPA states plainly that states can have more stringent applicability and reporting requirements. Burden scales with jurisdictions, not facility count: four plants in Kansas is one process, one plant in each of the four states is four.

Is the Tier II Deadline the Same in Every State?

Yes, March 1, in all four states, covering the prior calendar year. The deadline is the only thing that is uniform. Missouri opens its window January 1 and adds a 60-day new-EHS trigger plus a 24-hour fire department notice for explosives over 100 pounds; Kansas requires fees paid before March 1 under K.A.R. 28-65-4(a).

The uniform deadline is what makes the divergence dangerous. A calendar entry reading “Tier II due March 1” implies one task. It is four, with four failure modes, three of which start in December.

Does Kansas Accept the EPA Tier2 Submit File?

No. K.A.R. 28-65-3(b) requires Section 312 reports be completed using the Kansas tier II software and submitted electronically through tier2online.kdhe.ks.gov. There is no import path for a federal .t2s export. EPA’s own state page confirms Kansas facilities must submit using their web-based reporting system.

A master inventory built in Tier2 Submit because Oklahoma requires it does nothing for you at the Kansas state line. Kansas also blocks one attachment outright: the site plan cannot be uploaded and must be mailed as hard copy.

Where Is the Submit Button in the Kansas Tier II Portal?

There isn’t one, and KDHE says so under that exact heading: “You are working directly on the web so there isn’t any one button that ‘submits’ the Tier II report.” The filing is complete only when you send the certification letter and fee calculation worksheet with payment to the Right-to-Know Program. Zero-fee facilities must still send paperwork.

The closing step is a document-and-payment package, not a click: generate the fee calculation worksheet and the certification letter, pay, and send the packet to the Right-to-Know Program. One live conflict to resolve first: KDHE’s guidance PDF says the credit card payment form is retired in favor of PayIt, while the portal FAQ still points to the retired form. Call KDHE.

Does Missouri Accept the Federal Tier2 Submit File?

No. The Missouri Emergency Response Commission states: “Only the MISSOURI TIER II form is acceptable for EPCRA reporting in Missouri, we do not accept ‘Tier II Submit’ reports.” Accepted formats are manual entry at apps1.mo.gov/MERC or a wet-signed paper Missouri Tier Two form. Every chemical is re-keyed; there is no data portability from federal or commercial platforms.

For a Kansas and Missouri operator, that is the most operationally significant fact on this page. Sixty chemical line items across three Missouri plants is 180 manual entries that exist nowhere else in your compliance record, and every one is a place for a CAS number or a range code to drift. That data-quality half of the problem is covered in our Tier II reconciliation failure modes post.

The $100 Fee That Quietly Blocks Your Filing

Missouri is where a bookkeeping miss turns into a reportable violation, and the mechanism is live right now.

Missouri’s Tier II fee authority lapsed entirely on August 28, 2024 when the reauthorizing bill failed, costing local emergency planning committees roughly $650,000. SB 71 restored it effective August 28, 2025 for a six-year window that sunsets in 2031. To recover the gap, RSMo 292.606.7 imposed a one-time catch-up fee calculated on the March 1, 2025 filing and payable by November 1, 2025.

Here is the trap. MERC warns that unpaid balances appear on the fee sheet, and the portal will not accept a submission until past-due fees are paid. A missed $100 invoice becomes a blocked portal, then a missed March 1 filing, which is the conduct RSMo 292.615 penalizes at not more than $5,000 per violation for each day of violation, plus class C misdemeanor exposure. Nothing on the invoice says it is holding an environmental filing hostage. Check your Missouri balance in December, not in February.

What Are the Tier II Filing Fees in Kansas, Oklahoma, Missouri and Nebraska?

Nebraska charges nothing. Oklahoma charges $12 per facility for oil and gas operations and agricultural dealers, or $15 per hazardous substance and $30 per extremely hazardous substance, capped at $1,000 per company (OAC 252:20-1-7 fee schedule). Kansas charges $25 to $300 per facility, capped at $3,000 per owner/operator. Missouri charges $100 per employer plus $20 per chemical past the first three, capped at $10,000.

Watch the unit the cap attaches to. Kansas caps at $3,000 per owner or operator under K.S.A. 65-5704(b)(1)(D), not per facility, so an operator with eight Kansas plants benefits. Kansas also charges 10 percent per annum on outstanding fees; Missouri adds 10 percent of the total owed plus 1 percent per month.

How Do I Get a Nebraska Tier II Portal Login?

There is no online self-registration. Nebraska’s Department of Water, Energy and Environment mails facility ID numbers and passwords on a postcard each December or January, and the deq-iis.ne.gov/tier2 login page shows only ID and password fields. If you never received the postcard, call DWEE at 402-471-2186. Three failed password attempts inactivates the registration.

One correction to the version that circulates in industry forums: you do not have to wait for the mail. DWEE publishes a phone fallback, so a first-time filer, or a facility whose postcard went to a departed plant manager, calls instead. Do it in December. A credential you cannot issue yourself is a lead-time problem, and lead-time problems do not resolve in the last week of February.

For anyone maintaining checklists: LB905 section 53, operative July 1, 2026, terminates the Nebraska State Emergency Response Commission and substitutes the Nebraska Emergency Management Agency throughout Neb. Rev. Stat. 81-15,224. Any document naming “the Nebraska SERC” is now stale.

Do I Have to Send Tier II Copies to the LEPC and Fire Department Myself?

It depends on the state. Kansas and Nebraska require the facility to distribute; neither state forwards copies. Missouri lets you distribute or pay $10 per facility for MERC distribution (RSMo 292.606.3). Oklahoma is the outlier: OAC 252:20-1-6(c) deems the duty met by reporting to DEQ, which distributes.

That rule is stronger than the courtesy people assume it is: “Any requirement… to submit a paper Tier II report to the appropriate Local Emergency Planning Committee (LEPC) and to the local Fire Department is met by reporting to DEQ via electronic on-line internet reporting.” Oklahoma legally extinguishes the separate LEPC and fire department duty. Its three neighbors do not.

Oklahoma is the lowest-friction state in the region by statute: 27A O.S. 4-2-102(F)(2) bars member agency rules from being more stringent than any federal act. Assuming every state adds requirements costs you the one state where the federal file works.

What Is Changing on the 2027 Tier II Form?

EPA’s final rule of June 22, 2026 (91 FR 37022), effective August 21, 2026, replaces the merged EPCRA hazard categories with all 118 OSHA Hazard Communication Standard 2024 categories. The compliance date is January 1, 2028, first appearing in CY2027 reports due March 1, 2028. The old “flammable” category alone splits into 12.

EPA did not arrive there smoothly: it published a direct final rule in November 2025, withdrew it January 9, 2026 after adverse comment, then granted a 13-month compliance extension. The dates for your calendar: Tier2 Submit and CAMEO Data Manager 2027 versions release in November 2026, the revised National Tier II Data Standard follows in spring 2027, and the CY2026 reports filed March 1, 2027 still use the existing categories. Four states will implement the conversion on four schedules.

What Is the Penalty for Filing a Tier II Report Late?

Federally, $71,545 per violation per day under EPCRA Section 325(c)(1), which is 42 U.S.C. 11045(c)(1), as adjusted at 40 CFR 19.4. Section 11045(c)(3) makes each day a separate violation. Published guidance routinely miscites Section 325(b)(1)(A); that provision covers Section 304 release notification, not Tier II.

Two precision points. First, $71,545 is the January 8, 2025 adjusted figure and it is still operative, not a 2026 figure: OMB Memorandum M-26-11 of April 17, 2026 cancelled the 2026 civil penalty inflation adjustment entirely, so agencies continue using 2025 levels. Penalties are frozen, not rising. Second, the separate Section 311 safety data sheet obligation carries its own figure, $28,619 per violation per day under 11045(c)(2). One missed filing can breach both.

What Is the State Penalty for a Tier II Violation in Missouri, Kansas and Oklahoma?

Missouri: not more than $5,000 per violation for each day of violation under RSMo 292.615, brought by the Attorney General on a knowing and intentional finding, plus class C misdemeanor exposure. Kansas: up to $25,000 per violation and per day under K.S.A. 65-5708(c). Oklahoma: $10,000 misdemeanor fine plus $10,000 per day administrative. Nebraska sets no dollar figure.

Two structural details change the math. In Kansas, half the penalty goes to the county general fund when a county attorney brings the action, which gives a local prosecutor a direct reason to bring one. Oklahoma pairs its per-day administrative penalty with a three-year discovery look-back under 27A O.S. 2-3-502, so a gap that started in 2024 is still live.

Is EPA Actually Enforcing Tier II Violations?

Rarely, and less than it did. Verified Section 312-only settlements run $1,500 to $5,000 (Koch Foods $1,500; Modern Machinery $5,000). EPA ran roughly 8,300 inspections in FY2025 against about 468,735 covered facilities, and total civil penalties fell from $1.7 billion in FY2024 to just over $650 million in FY2025. The exposure is catastrophic; the detection rate is near 2 percent.

EPCRA Sections 311 and 312 have never been a National Enforcement and Compliance Initiative. The high-dollar EPCRA cases in the docket ($38,852 to $82,700) all bundle Section 312 with Section 313 Toxics Release Inventory counts; the clean Section 312-only actions are four figures. Nobody should sell you a Tier II program on the strength of a federal crackdown, because the record does not show one.

The real argument is worse. Low detection probability plus per-day accrual plus multi-year dormancy is a worse risk shape than aggressive enforcement, not a better one. Aggressive enforcement finds your gap in year one, at year-one size; this regime finds it in year four. The 2024 Nox-Crete case in Omaha carried its EPCRA counts only after a fire released 659,543 pounds and evacuated more than 2,000 residents. Tier II violations get discovered incident-first, not inspection-first. The trigger is the worst day your plant ever has.

There is an exit, and it has a clock. EPA’s eDisclosure system treats Tier II as a Category 1 violation eligible for an automatic electronic notice of determination with no civil penalty. A facility that self-discovers faces a 21-day window, not $71,545 per day, and both that clock and the correction deadline run from discovery. The discovery is the valuable event, which is the whole argument for looking before March.

What to Do Before December

  1. Build the facility list keyed to state, not to company. The process forks at the state line.
  2. Confirm threshold exceedance per chemical per site on the maximum amount present at any one time last year, not the average. Diesel in a 2,000-gallon tank runs roughly 14,000 pounds and clears the 10,000-pound threshold.
  3. Request portal credentials now. None of the three states that issue them is same-day.
  4. Clear any Missouri past-due balance before it blocks a March submission.
  5. Plan the format split: Tier2 Submit for Oklahoma, Kansas state software for Kansas, manual keying for Missouri and Nebraska.
  6. Assign LEPC and fire department distribution in Kansas and Nebraska, decide the $10 election in Missouri, do nothing further in Oklahoma.
  7. If you find a missed year, evaluate eDisclosure first.

Where iSi Fits

Most companies that get this wrong are not careless. They have one competent person carrying environmental compliance on top of a safety job, asked to hold four incompatible state procedures in his head during the same three weeks every year. That is a structural problem, not a diligence problem.

iSi runs multi-state Tier II filings as standing program work instead of a February scramble. Our EHS COOP retainer covers credential lead time, fee-status checks, the state-by-state format split and LEPC and fire department distribution in every state where you operate, with a national team across 40 states behind it. For multi-site operators without an environmental specialist on staff, our multi-site environmental compliance support does the same work site by site.

If you file in more than one state and are not certain what “submitted” means in each, that is a September question, not a February 28 question. Contact iSi Environmental and we will walk your facility list state by state.
