The Coast Guard Headquarters Office of Operating and Environmental Standards (CG- OES) and Commercial Vessel Compliance (CG-CVC) developed this circular to provide the latest guidance to maritime industry and Coast Guard personnel based on the 2012 ballast water regulatory amendments as set forth in references (a) through (c). In 2016, new compliance dates took effect for regulations that set the implementation schedule for ballast water management discharge standards for both existing and new vessels that use Coast Guard approved Ballast Water Management Systems (BWMS). Additionally, the regulations incorporated various compliance options for vessel owners or operators (to include masters, agents, and persons in charge), such as a vessel to use an Alternate Management System (AMS) until they reach their compliance date for installing a Coast Guard approved BWMS or employ one of the BWM practices or methods set forth in reference (a) and (b) regarding BWM requirements.

Ballast Water Management for Control of Non-Indigenous Species in Waters of The United States — This circular is to inform the maritime industry and Coast Guard personnel and provide

guidance to ensure a more complete understanding of, and maximum compliance with, ballast water management requirements.

Ballast Water Management for Control of Non-Indigenous Species in Waters of The United States — ACTION.

a. Vessel masters, owners, operators, agents, or persons-in-charge. U.S. and foreign flag commercial vessels that are equipped with ballast water tanks and operate in waters of the United States shall comply with the BWM regulatory requirements in references (a) through (c), as applicable. b. Vessel shipping agents. The Coast Guard encourages shipping agents to assist with the communication and coordination process that takes place before a vessel arrives into a U.S. port. Reminding vessel masters of BWM reporting, operational, and recordkeeping requirements helps ensure efficient compliance verifications during Coast Guard vessel examinations. NOTE: Direct all questions relating to BWM operations to the cognizant Captain of the Port (COTP) or Officer in Charge, Marine Inspection (OCMI); refer to the “Port Directory” on the Coast Guard Homeport website listed in enclosure (3) for a complete list of units, along with 24/7 contact information. c. U.S. Coast Guard. COTPs, OCMIs, marine inspectors and Port State Control Officers (PSCOs) that conduct BWM verifications shall be familiar with the guidance contained in this circular and are strongly encouraged to share and discuss this information with local maritime industry stakeholders. BWM compliance verifications shall be conducted as part of the regularly scheduled and expanded Port State and Flag State examinations.

Ballast Water Management for Control of Non-Indigenous Species in Waters of The United States — DISCUSSION.

a. The International Convention for the Control and Management of Ships’ Ballast Water and Sediments (BWM Convention) was adopted in February of 2004 and entered into force in September of 2017. Although the United States has not ratified the BWM Convention, we acknowledge this important milestone for controlling the spread of invasive species by ballast water as one of the greater challenges for reducing the environmental footprint of global shipping. b. In March of 2012, the Coast Guard published the final rule titled, “Standard for Living Organisms in Ships’ Ballast Water Discharged in U.S. Waters.” The rule became effective in June of 2012, whereby the Coast Guard amended its BWM regulations by establishing a standard for the allowable concentration of living organisms in ships’ ballast water discharged into waters of the United States. Furthermore, the rule amended Coast Guard regulations for engineering equipment by establishing an approval process for BWMS. The Coast Guard’s discharge standards NAVIGATION AND VESSEL INSPECTION CIRCULAR 01-18 are similar to those of the BWM Convention. However, differences exist between the testing and verification protocols for BWM systems. c. The Coast Guard is charged with protecting U.S. waters from invasive species, and highly values maritime industry’s commitment to that end. Vessel masters, owners, operators, and persons-in-charge are integral to training crews to properly maintain and effectively operate BWM equipment and achieve compliance. Enclosure (1) of this circular incorporates a list of topics that discuss pertinent U.S. regulations in references (a) through (c), while providing guidance on BWM reporting, recordkeeping, compliance and enforcement. Enclosures (2) and (3) provide a list of acronyms, useful website links and email addresses that are referenced in this circular.
