Michigan's Tier II reporting runs through the Tier II Manager online system, and the agency behind it might surprise you: it's administered by the Michigan State Police, not the state's environmental department.
Michigan's SARA Title III program sits inside the state police's Emergency Management and Homeland Security Division, which administers the Tier II Manager online submission system. That's a different home for this program than most states, where it's usually the environmental agency.
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 for the previous calendar year.
Reports are submitted online through Tier II Manager. As in most states, that submission satisfies your obligation to the state -- but your county LEPC and local fire department still need their own copies, typically as a PDF generated from the system, and it's worth confirming each one's preferred format directly rather than assuming they've pulled your data from the state system themselves.
If your facility has previously filed under Michigan's Department of Environmental Quality-era program name, note that administration has since moved to the state police -- old contact information or saved instructions referencing the environmental department may be pointing at the wrong office.
Michigan's Tier II Manager doesn't accept a .t2s upload, so HazRecord can't file into it directly. What it does is keep your chemical inventory and facility details current throughout the year, so your Tier II Manager entry is transcription from organized data rather than reconstruction under deadline pressure. The PDF copies for your LEPC and fire department still come from Tier II Manager itself once you've submitted there.
This guide is for general informational purposes only. It is not legal advice. Facilities remain responsible for verifying and submitting required reports to the appropriate federal, state, tribal, and local agencies.
HazRecord helps facilities organize chemical inventory, SDS records, storage locations, and Tier II reporting preparation in one place.
