IEMA is the state's Emergency Response Commission, and Tier II Manager is its online filing system -- each facility's username is tied to its physical address, and there's no.t2s or email alternative.
Who has to file, and when
Standard federal thresholds -- 10,000 pounds for hazardous chemicals, 500 pounds or the TPQ for extremely hazardous substances.40 CFR 370.10 Deadline is March 1st, covering the previous calendar year.
How Tier II Manager works
You gather your inventory, register or log into your account, and start a new report. Once it's certified, you print a final copy for your own records -- and this is the part worth underlining -- you print hard copies specifically for your LEPC and local fire department, not for IEMA. IEMA's own guidance says explicitly that hard copies mailed to them will not be accepted and will be shredded on arrival.
“I'll mail IEMA a signed hard copy just to be safe, in addition to filing online.”
Don't. IEMA's guidance states plainly that any hard copy sent to them will be shredded -- the paper copies go to your LEPC and fire department instead, some of which do accept email in place of a mailed copy, so it's worth checking each one's preference.
There's no filing fee at all in Illinois -- a genuine break from most of the states on this list, and one less thing to budget for during filing season.
Where HazRecord fits
Illinois only accepts entry through Tier II Manager -- HazRecord doesn't file into IEMA's system for you. What it does is keep your chemical inventory, thresholds, and storage locations organized year-round, so when it's time to log into Tier II Manager, you're transcribing clean, current data instead of reconstructing it from scratch. The hard copies for your LEPC and fire department still come from what Tier II Manager prints once you've certified your report there.
