Unauthorized Shipment of Anhydrous Ammonia Discovered at Puerto Nuevo Terminals

A recent Coast Guard inspection at Puerto Nuevo Terminals (PNT) in San Juan, Puerto Rico, uncovered an unauthorized shipment of Anhydrous Ammonia, a highly toxic and corrosive substance. This discovery was made during a routine examination by Coast Guard Marine Science Technicians, who identified three tank-containers at the facility, with one container found to contain over 5,000 gallons of the hazardous material.

PNT, which was already under restrictions for handling hazardous materials, had been issued a Captain of the Port Order on February 27, 2025, prohibiting the storage and handling of certain hazardous materials due to inadequate firefighting capabilities. This recent incident raises serious concerns about the facility’s compliance with safety regulations.

Responding to the discovery, a spokesperson for Puerto Nuevo Terminal expressed their commitment to prioritizing the safety of operations and stated that they are working closely with the US Coast Guard to address the issue promptly. Additional safety measures have been implemented for all commodities entering PNT as a precautionary measure.

Earlier in February, PNT had its permit suspended following unauthorized handling of ammonium nitrate, a chemical infamous for its involvement in the devastating 2020 Beirut explosion. The subsequent interagency response involved multiple federal agencies conducting a thorough inspection of the terminal’s containers.

Coast Guard Sector San Juan commander, Capt. Robert E. Stiles, commended the diligence of the inspection team and emphasized the importance of port safety and security. Investigations into the matter are ongoing to ensure compliance with federal laws and regulations.

Violations of a Captain of the Port Order can result in significant penalties under federal law, including civil penalties and felony charges for willful violations. PNT is currently permitted to handle non-hazardous general cargo but must meet specific safety requirements before resuming hazardous material operations.

With a focus on safeguarding the local population and maintaining maritime industry operations, Captain Stiles reiterated the commitment to ensuring that hazardous materials are handled in compliance with regulations to prevent any potential catastrophic incidents.
