Yes, collecting sea glass is legal in New Hampshire, provided it adheres to state and federal environmental protections. The New Hampshire Department of Environmental Services (NHDES) permits casual collection for personal use, but commercial harvesting requires permits under the Coastal Zone Management Act and local ordinances.
Key Regulations for Collecting Sea Glass in New Hampshire
- NHDES Coastal Program Compliance: Collection must not disrupt protected habitats or violate the Coastal Zone Management Act, enforced by NHDES. Violations may trigger fines up to $27,500 under the Clean Water Act.
- Local Municipal Ordinances: Coastal towns like Hampton and Rye may impose seasonal restrictions (e.g., no mechanized tools) to protect intertidal zones. Always verify town-specific rules before collecting.
- Federal Endangered Species Act (ESA): Removing sea glass from habitats of protected species (e.g., Spartina patens marsh grass) is prohibited. The U.S. Fish & Wildlife Service monitors compliance, particularly near Great Bay.
Commercial collectors must obtain a NHDES Coastal Use Permit and comply with the NH Shoreland Water Quality Protection Act, which restricts volume and location of extraction. The 2026 NHDES permit renewal cycle introduces stricter reporting for large-scale operations. Always document permits and avoid protected areas like Great Bay Estuary and Piscataqua River tributaries.
