A Garbage Dumping Placard Must Be Prominently Posted

Federal law requires every manned U.S. vessel 26 feet or longer to display at least one durable placard, measuring at least 20 by 12.5 centimeters, in prominent locations where crew and passengers can read it — galleys, garbage handling areas, living quarters, common deck spaces, and embarkation points. Garbage dumping placard requirements sit in 33 CFR 151.59, and they cover placement, content, size, and language. A single violation can carry a civil penalty of up to $25,000, so the details matter.1eCFR. 33 CFR 151.59 – Placards

Which Vessels Need a Placard

The rule applies to every manned U.S. ship measuring 26 feet or more in overall length. That covers recreational boats, commercial fishing vessels, charter boats, and drilling rigs or platforms. Inland waters, the Great Lakes, and the open ocean are all treated the same way: if the vessel is manned and hits the length threshold, a placard is required.1eCFR. 33 CFR 151.59 – Placards

Foreign-flagged ships carry the same obligation the moment they enter U.S. navigable waters or dock at a port or terminal under U.S. jurisdiction.1eCFR. 33 CFR 151.59 – Placards Unmanned barges and automated platforms fall outside the “manned ship” language, but once someone is aboard and the vessel is 26 feet or longer, the requirement applies. Measure overall length bow to stern, not waterline length, and if you are close to the threshold, assume you need to comply.

Where the Placard Must Be Posted

The regulation calls for placards in “prominent locations and in sufficient numbers so that they can be read by the crew and passengers.” Instead of naming one mandatory spot, it identifies categories of qualifying locations:1eCFR. 33 CFR 151.59 – Placards

  • Food service areas — galleys, mess halls, and anywhere food is prepared or consumed.
  • Garbage handling spaces — wherever trash is collected, sorted, or stored.
  • Living quarters and common areas on deck — crew quarters, lounges, and open deck spaces where people gather.
  • Embarkation points — the boarding areas where passengers first come aboard.

On a small recreational boat without a galley or dedicated trash station, mounting the placard near the helm or beside the trash receptacle satisfies the standard. The working test is whether someone handling garbage would see it during normal activity. A placard tucked inside a closed locker, behind equipment, or under a seat does not meet the visibility requirement. If the local Captain of the Port decides your existing placards aren’t reaching enough people, that officer can order additional signs and specify where they go.1eCFR. 33 CFR 151.59 – Placards

What the Placard Must Say

A generic “don’t litter” sign will not do. The placard has to communicate the actual discharge rules so anyone reading it understands what can go overboard, what cannot, and at what distance from shore. At a minimum, the content must convey:1eCFR. 33 CFR 151.59 – Placards

  • Garbage discharge is prohibited in U.S. navigable waters and within 3 nautical miles of land in other waters, with only narrow exceptions.
  • Plastic is banned everywhere. No plastic of any kind — bags, bottles, synthetic rope, fishing nets — may be thrown overboard at any distance from shore.
  • Violators face civil and criminal penalties.
  • State and local restrictions may also apply.

The Coast Guard has published sample placard language through policy guidance that spells out the zone-based rules in plain terms. That sample text explains what is allowed outside MARPOL Special Areas versus inside them, and it notes that ground food waste may be discharged beyond 3 nautical miles while unprocessed food waste requires at least 12 nautical miles.2United States Coast Guard. CG-CVC Policy Letter 13-01 Most commercially printed placards follow this approved format, which makes compliance straightforward: you buy one, mount it correctly, and you have met the content requirement.

Size, Material, and Language

The placard must measure at least 20 centimeters wide by 12.5 centimeters high — roughly 8 by 5 inches. It has to be made of durable material and stay legible through constant exposure to salt spray, humidity, and sunlight.1eCFR. 33 CFR 151.59 – Placards Heavy-gauge plastic or anodized metal plates that can be screwed or bolted to a bulkhead hold up well. Adhesive-backed stickers tend to peel in marine conditions and are a poor long-term choice.

Every placard must be printed in English. If your crew or passengers primarily speak a different language, the placard must also appear in that language, either as a bilingual sign or as a separate placard posted alongside the English one.1eCFR. 33 CFR 151.59 – Placards A boarding officer who finds a non-English-speaking crew with only an English placard can cite that as a violation. Vessels with multinational crews often post three or four versions of the same sign.

When You Also Need a Written Garbage Management Plan

Placards are only part of the picture. Under 33 CFR 151.57, certain vessels must also carry a written garbage management plan describing procedures for collecting, processing, storing, and discharging garbage under MARPOL Annex V, and naming a specific person responsible for carrying it out.3eCFR. 33 CFR 151.57 – Garbage Management Plans Recreational vessels 40 feet and longer that are not engaged in commerce, along with any vessel 26 feet and longer that is engaged in commerce, fall under this requirement.1eCFR. 33 CFR 151.59 – Placards

The master or person in charge has to keep the plan physically on board and see that everyone handling garbage actually follows it. Inspectors will ask to see the document, and they will check whether the crew knows what it says.

Penalties for Getting It Wrong

Under 33 U.S.C. 1908, the civil penalty for each violation of MARPOL garbage rules can reach $25,000, and each day a continuing violation persists counts as a separate offense.4Office of the Law Revision Counsel. 33 USC 1908 – Penalties for Violations Authorities weigh the nature and gravity of the violation, the violator’s history, and ability to pay when they set the amount.

A knowing violation, meaning deliberate dumping of prohibited garbage or falsifying records, is a Class D felony carrying potential imprisonment. A false statement in any required report adds a separate civil penalty of up to $5,000 per statement.4Office of the Law Revision Counsel. 33 USC 1908 – Penalties for Violations A missing or poorly placed placard rarely triggers the heaviest penalties on its own, but it draws inspector attention to the rest of your compliance, and that is where the expensive findings surface. During routine boardings, safety exams, and port-state control inspections, officers check for both the placard and, where applicable, the written garbage management plan.5United States Coast Guard. Annex V – Regulations for the Prevention of Pollution by Garbage from Ships A vessel found deficient can receive anything from a formal citation to detention in port until the problems are corrected.
