Summer Is Your Compliance Window — What Michigan Schools Need to Do Before Fall
Key Takeaways
- Summer is the best — and often only — window to complete environmental testing and inspections in school buildings.
- Michigan's Filter First Annual Certification deadline is August 31, 2026 — time is short.
- AHERA requires periodic asbestos inspections; summer is the required window for many re-inspections.
- Radon testing in schools is gaining traction in Michigan — summer closed-building conditions are ideal for accurate measurement.
- ETC handles all three — one call, one team, no juggling multiple vendors before the school year starts.
When the last bell rings and students head out for summer, most school facilities teams finally get something they haven't had all year: access. Empty hallways, quiet classrooms, and buildings that aren't full of people who need to be protected from disruption.
That window is short — and it's the right time to knock out the environmental compliance work that can't happen when students and staff are in the building. Here's what Michigan school districts should be tackling this summer, and why waiting until fall is not an option for some of it.
1. Filter First Annual Certification — Deadline August 31
Filter First Compliance
Due August 31, 2026Michigan's first-ever Annual Filter First Certification is due August 31, 2026 — and building administrators have already started receiving notices from MiEHDWIS, the state's Environmental Health and Drinking Water Information System.
To certify, schools need to confirm the status of their Filter First requirements for the 2025–2026 school year. That means having a completed fixture inventory and an on-site Drinking Water Management Plan (DWMP). If either of those isn't done, summer is the time to get them across the finish line.
The good news: buildings don't need to be fully compliant to certify. The system records your current status — it's not a pass/fail. But you do need to have submitted by August 31, and the account setup and documentation process takes longer than most people expect.

2. AHERA Asbestos Inspections — The Summer Window Is Required
AHERA Asbestos Compliance
Periodic Re-Inspections RequiredThe Asbestos Hazard Emergency Response Act (AHERA) requires all public and private non-profit K-12 schools to inspect for asbestos-containing materials, maintain management plans, and conduct periodic re-inspections every three years. For many districts, that re-inspection is overdue — or coming up fast.
Summer is the practical and often required window for these inspections. With buildings unoccupied, inspectors can access all areas without disrupting students and staff. Post-abatement clearance testing — required after any asbestos abatement work — also needs to happen before occupants return.
ETC's lab, ETL, is the only NVLAP-accredited TEM asbestos analysis laboratory in Michigan, which means we can handle both the inspection side and the lab analysis side in-house — faster turnaround, fewer coordination headaches for your district.

3. Radon Testing — Get Ahead of an Emerging Requirement
Radon Testing
Emerging RequirementRadon testing in schools is gaining significant momentum in Michigan, and districts that get ahead of it now will be in a much stronger position as requirements continue to evolve. Radon is a naturally occurring radioactive gas that can accumulate in buildings — particularly in lower levels — and is the second leading cause of lung cancer in the United States.
Summer is the ideal time for closed-building radon measurements. With windows closed and HVAC systems running in normal mode, testing conditions more accurately reflect real-world exposure for students and staff during the school year. Testing during the school year with buildings full of people is more disruptive and can be harder to schedule.
Getting a baseline reading now gives your district the data it needs to make informed decisions — and documentation to demonstrate proactive action if and when requirements formalize.

Your Summer Compliance Checklist
Before students return in the fall, Michigan school districts should have the following in hand:
- Filter First certification submitted in MiEHDWIS by August 31, 2026
- Fixture inventory completed for each building, documenting all consumptive and non-consumptive sources
- Drinking Water Management Plan (DWMP) finalized and available on-site at each building
- AHERA re-inspection completed if your three-year cycle is due, with updated management plan
- Post-abatement clearance testing completed if any asbestos abatement work was performed this summer
- Radon baseline testing completed for lower-level and high-risk areas of each building
