Scattering ashes at sea is one of the most peaceful and popular ways to say goodbye. The ocean's vastness offers families a sense of freedom, connection, and permanence that a cemetery plot cannot, and it is why sailors, veterans, and ocean lovers so often choose it. But while the tribute is timeless, it is also regulated: the U.S. Environmental Protection Agency (EPA) sets specific rules you must follow to do it legally and respectfully.
This guide walks you through everything involved in scattering ashes at sea -- the EPA's requirements, how far offshore you must go, whether you need to notify the agency, what kind of urn to use, and how to plan a meaningful ceremony. Whether you charter a boat, go with a captain, or handle it yourself, a little preparation ensures the day goes smoothly and honors your loved one.
Is Scattering Ashes at Sea Legal?
Yes, scattering ashes at sea is fully legal in the United States, but it falls under the federal Marine Protection, Research, and Sanctuaries Act, administered by the EPA. The rules are straightforward and exist to protect marine environments and other people using the water.
The core EPA requirements for scattering ashes at sea are:
- Distance: Cremated remains must be released at least three nautical miles (about 3.45 land miles) from shore. This is the single most important rule.
- Materials: Anything placed in the water with the ashes -- such as an urn or flowers -- must be readily decomposable in the marine environment. No plastic, metal, or non-biodegradable containers.
- Notification: You must notify the EPA within 30 days of the burial at sea, reporting the date, location (latitude and longitude), and nature of what was released.
Cremated remains themselves are considered safe for the ocean because the cremation process renders them sterile and inert. For a broader look at where releasing ashes is permitted, see our guide on where you can scatter ashes legally.
The EPA 3-Mile Rule Explained
The three-nautical-mile requirement is the rule families most often overlook. You cannot scatter ashes from a pier, a beach, or just beyond the surf -- you must be at least three nautical miles offshore in water. This generally means you will need a boat.
A few practical notes on the distance rule:
- Three nautical miles equals roughly 3.45 statute (land) miles.
- Some areas have deeper-water recommendations; the EPA suggests waters at least 600 feet deep where feasible, and certain regions require greater depths.
- A GPS-equipped boat makes it easy to confirm you have passed the boundary before the ceremony.
If you do not own a boat, you have three common options: charter a private boat with a captain, book a dedicated scattering-at-sea service, or ask a boat-owning friend or family member. Many coastal funeral homes and charter captains offer packages specifically for this purpose.
How to Notify the EPA
Notification is required but simple, and there is no fee or permit application to file beforehand. You do not need EPA permission in advance -- you simply report the burial after it happens.
Within 30 days of scattering ashes at sea, submit a report to the EPA regional office covering the area where the release occurred. The report should include:
- The date of the burial at sea.
- The exact location, given as latitude and longitude coordinates.
- The type of remains (cremated remains).
- Your name and contact information.
Most EPA regions accept this notification through an online form or by email. If you use a professional scattering service or charter captain, they typically handle the EPA notification for you as part of the package -- always confirm this is included. The report exists for recordkeeping and marine safety, not to grant or deny permission.
Choosing a Biodegradable Urn
If you want to lower a container into the water rather than pour ashes directly, it must dissolve or break down naturally. Purpose-made biodegradable urns for water are inexpensive and widely available.
| Urn Type | Material | How It Works |
|---|---|---|
| Floating water urn | Salt, sand, or paper pulp | Floats briefly, then sinks and dissolves within minutes to hours. |
| Sand/gelatin urn | Compressed sand or gelatin | Sinks and breaks down in the water. |
| Paper or bark urn | Recycled paper, mulberry bark | Biodegrades naturally after release. |
| Scattering tube | Cardboard | For pouring ashes directly, not submersion. |
Avoid any urn made of plastic, metal, glass, or coated wood, as these violate EPA rules and harm marine life. Fresh flowers are permitted and make a beautiful addition, but remove any plastic wrapping, rubber bands, or ribbons first. For more on container choices, see our cremation urns buying guide.
Planning the Ceremony
Beyond the legal rules, a sea scattering is deeply personal, and thoughtful planning makes it memorable.
- Choose the right day and tide. Calm morning waters are easiest. A local captain can advise on conditions and avoid seasickness for guests.
- Consider the wind. Always scatter ashes on the downwind side of the boat so they carry away from passengers, never into the wind.
- Prepare a few words. A short reading, prayer, poem, or moment of silence gives the ceremony shape. Many families release flowers or biodegradable petals afterward.
- Capture the location. Record the GPS coordinates so family can return to the spot on future anniversaries.
- Bring the paperwork. Keep a copy of the cremation certificate and note the details you will need for EPA notification.
If some family members cannot attend, consider dividing the ashes among family so others can keep or memorialize a portion. Coastal cities like San Diego, Miami, New York, Seattle, and Gulf ports near Houston have many charter services experienced with respectful scatterings.
Free Burial at Sea for Veterans
Many families don't realize that the U.S. Navy offers a free burial at sea for eligible veterans, active-duty service members, and certain family members. The ceremony is performed by the crew of a Navy vessel while it is deployed, and the family receives a letter afterward with the date, time, and coordinates of the committal.
Because the ceremony happens during regular deployments, families are not present, and there can be a wait of several months to over a year. To arrange it, you provide the cremated remains along with required documents such as the death certificate, cremation certificate, burial transit permit, and proof of military service (the DD-214). Contact the Navy Mortuary Affairs office to begin. For other benefits, see our guide on cremation for veterans and military.
Inland Waters, Rivers, and Lakes
The EPA's ocean rules apply to the sea, but scattering in rivers, lakes, or other inland waters is governed differently -- usually by the Clean Water Act and state or local regulations. In many cases you need a permit, and some waterways prohibit it entirely.
If you are considering a river or lake rather than the ocean, check with your state environmental agency first. Our guide on what to do with cremation ashes covers the full range of scattering, burial, and keepsake options so you can choose what feels right.

Frequently Asked Questions
How far out do you have to be to scatter ashes at sea?
The EPA requires that cremated remains be scattered at least three nautical miles from shore, which is roughly 3.45 land miles. You cannot legally scatter ashes from a pier or beach. This distance almost always requires a boat, whether chartered, professionally arranged, or borrowed.
Do I need a permit to scatter ashes at sea?
You do not need advance permission or a permit, but you must notify the EPA within 30 days of scattering ashes at sea. The notification reports the date, location coordinates, and type of remains. Professional scattering services and charter captains usually handle this notification for you.
What kind of urn can I use to scatter ashes in the ocean?
The urn must be readily decomposable in the marine environment. Biodegradable water urns made of salt, sand, paper, or gelatin are ideal -- they float briefly then dissolve. Avoid plastic, metal, glass, or coated materials, which violate EPA rules and harm marine life.
Can I scatter ashes at sea myself without a service?
Yes. If you have access to a boat and can travel at least three nautical miles offshore, you can scatter ashes yourself. Just follow the EPA rules, use a biodegradable urn if submerging one, scatter downwind, record the coordinates, and file the EPA notification within 30 days.
Are cremated remains harmful to the ocean?
No. The cremation process renders remains sterile and inert, so they pose no danger to marine life or water quality. The EPA rules focus mainly on distance from shore and ensuring any container or flowers used are biodegradable rather than plastic or metal.
Can I scatter ashes in a lake or river instead?
Inland waters like lakes and rivers are governed by the Clean Water Act and state or local rules rather than the EPA's ocean regulations. Many require a permit or prohibit scattering entirely. Always check with your state environmental agency before scattering ashes in fresh water.
