How Idaho takes it
Idaho takes the Tier2 Submit file by email to tier2@imd.idaho.gov.
The file we build is the one this state works from.
The filing is due 1 March each year and covers the calendar year before it. Idaho does not pass it on for you — we checked. Filing closes the state’s copy only; your local committee and fire department each need their own from you.
Before you send it — what else Idaho asks for
Idaho expects the same report sent to your LEPC and your local fire department yourself — emailing the state does not cover those. Idaho publishes a directory of LEPC and local emergency response authority addresses to send to. Idaho takes the file we build — its emergency management office “requires use of the Tier2 Submit software or Tier II form (where applicable)” — and completed reports go by email to tier2@imd.idaho.gov. Send it to three places, though: IOEM, your local emergency planning committee and your local fire department. Idaho’s page names no filing fee.
Does Idaho set its own limits?
Idaho's own agency says it uses the federal thresholds, and we read that page rather than assuming it. We have not gone behind it to the state code, so we say that too.
Idaho applies the federal thresholds unchanged. The state asks you to file with EPA’s Tier2 Submit — the same file we build — and a new version of that software comes out around November each year, so start from the current one rather than last year’s copy.
The words we read
US EPA, “State Tier II Reporting Requirements and Procedures” — Idaho section. EPA’s compilation states the submission route and any state-added fields; it records no state threshold below the federal 10,000 lb / 500 lb-or-TPQ tests. Idaho Office of Emergency Management, Tier II page, read 2026-09-07: it describes the duty in federal terms — facilities “covered by the Emergency Planning and Community Right to Know Act (EPCRA)” must file annually — and states no Idaho threshold at all. The numbers we apply are the federal ones in 40 CFR 370, which we read directly. Idaho Code title 39, chapter 71, the Hazardous Substance Emergency Response Act (legislature.idaho.gov), section list read 2026-09-08: short title, findings, definitions, the Military Division’s responsibilities, local emergency response authorities, notification of a release (§ 39-7108), reimbursement of response costs, liability, cost recovery, good-samaritan immunity, private emergency response plans, the Civil Air Patrol, severability. The chapter is about who responds to a release and who pays for it; it contains no chemical inventory filing and no quantity, so the federal thresholds are what apply. We read the chapter’s section list, not the body of each section, so we describe § 39-7108 by its title only.
