What is Fibrosan?
A fiberglass laminate manufacturing plant
Fibrosan Inc. plans to build a fiberglass laminate manufacturing plant that uses toxic chemicals to make large panels for RVs, trailers, and other products.
Their process uses styrene, MMA, resins, gelcoats, acetone, and liquid organic peroxides.
Styrene
EGLE (Michigan’s environmental regulator) identifies styrene as a hazardous air pollutant and says it is known to be odorous.
Proposed annual emission limits for EULAMINATE
From EGLE Permit Materials (April 2026)
Total VOCs
(Volatile Organic Compounds)
119.47
Tons per year
Total Organic HAPs
(Hazardous Air Pollutants)
98.14
Tons per year
EGLE identifies the proposed facility as a major source of hazardous air pollutants and a major source of volatile organic compounds.
The chemicals. The risks.
Serious health and environmental hazards
Safety data sheets for chemicals used in Fibrosan’s proposed process warn of serious health and environmental hazards.

Fire & explosion risks
- Highly flammable
- Vapors can travel and ignite
- May polymerize explosively (MMA)
- Water is NOT effective for putting out fires
- Excess pressure may cause containers to rupture
≈
Environmental risks
- Harmful to aquatic life with long-lasting effects.
This is a potentially hazardous industrial facility in the middle of our community.
A massive tax break for a potentially massive polluter
- Fibrosan is asking for a 12-YEAR INDUSTRIAL FACILITIES TAX EXEMPTION (IFT).
- Estimated state and local tax reduction: APPROX. $2.28 MILLION over 12 years.
- The proposed IFT would reduce property taxes on qualifying new building and equipment by roughly 50% for up to 12 years.
A sneaky, slimy process
How Cassopolis leadership has handled the Fibrosan deal
Construction began before the air permit was issued
EGLE cited Fibrosan for beginning construction without an issued Permit to Install or construction waiver.
Information withheld
Key documents and the real nature of Fibrosan’s operation were hidden or downplayed—residents learned the truth only after the deals were already in motion.
Inadequate public hearing
The hearing was held at 3:45 PM in a room too small to accommodate residents. A woman in a wheelchair was left sitting in an aisle. Only 3 council members showed up.
Last-minute “fact sheet”
Critical information about the tax break, job numbers, and costs was handed out at the hearing—giving the public no time to review or respond.
Moving targets & changing claims
First it was 32 jobs. Now it’s “more than 100.” Fibrosan later said an RTO would be installed, but residents still have questions because it was not reflected in the permit materials many people reviewed.
Promoting Fibrosan to outsiders
The Village Manager mailed a pro-Fibrosan letter to Diamond Lake residents outside Village limits—raising questions about the use of public resources to promote this deal.
Accountability? Nowhere to be found
- Where is the SMART Park Development Committee’s review and records?
- How does Fibrosan comply with the covenant that bans “unreasonably dangerous materials”?
- Who approved this deal, and why aren’t the documents public?
- Why has the Village President dismissed residents as “outside voices” instead of answering hard questions?
- Are our leaders more loyal to corporations than to the people who live here?
What we want
Our health. Our air. Our town. Our future.
