Scattering Ashes in Maryland: Rules for Private Property, Waterways, State Parks, and Burial at Sea

After cremation, families often want a meaningful way to scatter ashes in a place that held significance to the person who died — a family property, a favorite hiking trail, a stretch of Chesapeake Bay. The rules for where scattering is permitted in Maryland depend on who owns the land and what type of waterway or location is involved.

The good news is that Maryland law gives families substantial freedom. The complications arise primarily on public land and in navigable waterways — and the federal EPA has rules that apply regardless of where in Maryland you are.

Scattering Ashes on Private Property

The simplest scenario under Maryland law: if you own the property, you can scatter cremated remains on it. There are no state restrictions on scattering ashes on your own land.

If the property belongs to someone else — a friend, a family member, a business owner — you need their written or documented permission. Maryland does not require this permission to be notarized or in any particular form, but having it in writing is wise if there is any possibility of a future question.

What you do not need:

• A permit from the state
• Notification of any state agency
• A specific container or method of scattering

Cremated remains from conventional flame cremation (bone fragments processed into fine powder) are chemically inert — primarily calcium phosphate — and pose no public health risk. There are no Maryland rules prohibiting scattering on privately owned land.

Note: Soil remains from human composting (natural organic reduction) are subject to different rules. They cannot be placed on any property without the written permission of the property owner, and they cannot be used in food production. For that topic specifically, see our post on human composting in Maryland.

Scattering Ashes in Maryland Waterways

Maryland is bounded by the Chesapeake Bay and the Atlantic Ocean, and threaded with rivers, reservoirs, and tidal waters. The rules for scattering depend on the type of waterway.

Navigable Waterways and the Chesapeake Bay

For scattering in navigable waterways — including the Chesapeake Bay and its major tributaries — the relevant rules are primarily federal, set by the EPA under the Marine Protection, Research, and Sanctuaries Act.

For burial at sea (which the EPA defines as scattering more than 3 nautical miles from shore in navigable ocean waters), EPA rules require:

• The scattering must occur at least 3 nautical miles offshore
• Within 30 days of scattering, you must report the location, date, and time to the EPA (this can be done online at epa.gov)
• Flowers and other biodegradable materials may be scattered with the ashes
• Non-biodegradable items (urns, plastic flowers) may not be deposited in the water

For scattering in inland navigable waterways (rivers, the Bay itself in areas closer to shore), the EPA burial-at-sea rule technically applies only beyond 3 nautical miles. Scattering in inland waterways is a gray area at the federal level — the EPA rules don't explicitly cover it, and Maryland has no specific state statute prohibiting it.

Practically, many families scatter ashes in the Chesapeake Bay from boats without incident. There is no active enforcement of ashes scattered in the Bay itself. If you are in doubt, the most legally clear path is to go offshore (more than 3 nautical miles) and follow EPA notification procedures.

Reservoirs and Drinking Water Supplies

Scattering ashes in reservoirs used as public drinking water supplies is generally prohibited. Contact the water authority that manages the specific reservoir to confirm their policy. Some reservoirs have their own rules posted.

Private Waterways and Farm Ponds

Ponds and streams on private property follow the same private property rules: permission of the landowner is what matters.

Scattering Ashes in Maryland State Parks and Public Land

Maryland state parks and public lands are governed by the Maryland Department of Natural Resources (DNR). Maryland DNR generally allows scattering of cremated remains in state parks and forests, but individual parks may have specific guidance.

The best practice is to contact the specific park's visitor center or superintendent before scattering. Most parks:

• Do not require a permit for scattering cremated remains in non-sensitive areas
• May restrict scattering in sensitive ecological areas (nesting grounds, rare plant habitats)
• May have designated areas for scattering

Do not scatter in areas that are clearly marked as restricted. Do not scatter from trails in a way that is visible to other park visitors who may find it distressing.

For national parks within Maryland (Chesapeake and Ohio Canal, Assateague Island National Seashore, Antietam National Battlefield), the rules are set by the National Park Service. NPS policies vary by park — some allow scattering with advance notice to the superintendent, others prohibit it in certain areas. Contact the specific park's administration before proceeding.

Taking Ashes Out of State or Out of Country

If you want to scatter ashes at a meaningful location in another state or country, the logistics are simpler than many families expect.

Traveling domestically with ashes: TSA allows cremated remains in carry-on luggage. The container must pass through X-ray screening; TSA will not open a sealed urn. Many families choose a temporary plastic or cardboard container for travel and transfer to a more significant container after scattering.

Traveling internationally with ashes: Each country sets its own rules. Some countries (Japan, for example) have strict import requirements for cremated remains, including documentation. Research the destination country's customs requirements before traveling. A certified copy of the death certificate and cremation certificate should travel with you.

Mailing ashes: The U.S. Postal Service allows cremated remains to be shipped by USPS Priority Mail Express with specific packaging requirements. FedEx and UPS do not accept cremated remains.

Documentation to Keep After Cremation

After receiving cremated remains, retain:

• A copy of the cremation certificate (provided by the crematory)
• A copy of the death certificate
• Any burial transit permit documentation

These documents may be requested at international customs, by airlines, or by the EPA when filing a burial-at-sea report. Keep them in a safe location.

For families navigating the full process from the cremation waiting period through final disposition, see our post on the Maryland cremation waiting period for the timeline before remains are returned.

The Maryland Funeral Laws & Consumer Rights Guide includes a checklist covering disposition options for cremated remains, from home storage to scattering to permanent interment in a columbarium.
