Yes, collecting sea glass is generally legal in Illinois, provided it adheres to state and local environmental protections. While no statute explicitly bans the activity, compliance with Illinois’ Coastal Zone Management Act and local ordinances is mandatory. The Illinois Department of Natural Resources (IDNR) monitors shoreline activities to prevent ecological disruption. Recent 2026 guidance from the IDNR emphasizes sustainable collection practices to mitigate harm to fragile ecosystems.
Key Regulations for Collecting Sea Glass in Illinois
- Protected Shorelines: Collecting sea glass from Illinois’ Lake Michigan shoreline within designated conservation areas (e.g., Illinois Beach State Park) is prohibited without a permit. Violations may incur fines up to $10,000 under the Illinois Environmental Protection Act.
- Size and Quantity Limits: The IDNR’s 2026 guidance caps personal collection to 10 pounds per visit in non-protected zones to prevent depletion of natural resources. Commercial harvesting requires a separate permit under the Illinois Commercial Fishing Act.
- Permit Requirements: Any organized collection events (e.g., group digs) must secure prior approval from the IDNR’s Coastal Management Program. Failure to comply may result in permit revocation and legal penalties.
Local municipalities, such as the City of Chicago’s Department of Environment, may impose additional restrictions. Collectors should verify zoning laws and shoreline access rules before engaging in the activity. Violations of the Illinois Endangered Species Protection Act could apply if collection disrupts protected habitats.
