33 CFR § 151.1510 - Ballast water management requirements.
(a) The master of each vessel subject to this subpart shall employ one of the following ballast water management practices:
(1) Carry out an exchange of ballast water on the waters beyond the Exclusive Economic Zone (EEZ), from an area more than 200 nautical miles from any shore, and in waters more than 2,000 meters (6,560 feet, 1,093 fathoms) deep, such that, at the conclusion of the exchange, any tank from which ballast water will be discharged contains water with a minimum salinity level of 30 parts per thousand, unless the vessel is required to employ an approved ballast water management system (BWMS) per the schedule in § 151.1512(b) of this subpart. This exchange must occur prior to entry into the Snell Lock at Massena, NY, or navigating on the Hudson River, north of the George Washington Bridge. An alternative management system (AMS) that meets the requirements of 33 CFR 151.2026 may also be used, so long as it was installed on the vessel prior to the date that the vessel is required to comply with the ballast water discharge standard in accordance with § 151.1512(b) of this subpart. If using an AMS, the master, owner, operator, agent, or person in charge of the vessel subject to this subpart may employ the AMS for no longer than 5 years from the date they would otherwise be required to comply with the ballast water discharge standard in accordance with § 151.1512(b) of this subpart.
(2) Retain the vessel's ballast water on board the vessel. If this method of ballast water management is employed, the COTP may seal any tank or hold containing ballast water on board the vessel for the duration of the voyage within the waters of the Great Lakes or the Hudson River, north of the George Washington Bridge.
(3) Install and operate a BWMS that has been approved by the Coast Guard under 46 CFR part 162, in accordance with § 151.1512(b) of this subpart. Following installation of a BWMS, the master, owner, operator, agent, or person in charge of the vessel must maintain the BWMS in accordance with all manufacturer specifications.
(ii) Requests for approval of BWMS must be submitted to the Commanding Officer (MSC), Attn: Marine Safety Center, U.S. Coast Guard Stop 7430, 2703 Martin Luther King Jr. Avenue SE., Washington, DC 20593–7430, or by email to email@example.com.
(4) Use only water from a U.S. public water system (PWS), as defined in 40 CFR 141.2 and that meets the requirements of 40 CFR parts 141 and 143, as ballast water. Vessels using water from a PWS as ballast must maintain a record of which PWS they received the water and a receipt, invoice, or other documentation from the PWS indicating that water came from that system. Furthermore, they must certify that they have met the conditions in paragraphs (a)(4)(i) or (ii) of this section, as applicable. Vessels using water from a PWS must use such water exclusively for all ballast water unless the usage is in accordance with § 151.1515 of this subpart. Vessels using PWS water as ballast must have either—
(i) Previously cleaned the ballast tanks (including removing all residual sediments) and not subsequently introduced ambient water; or
(ii) Never introduced ambient water to those tanks and supply lines.
(b) No master of a vessel subject to this subpart shall separately discharge sediment from tanks or holds containing ballast water unless it is disposed of ashore in accordance with local requirements.
(c) Nothing in this subpart authorizes the discharge of oil or noxious liquid substances (NLSs) in a manner prohibited by United States or international laws or regulations. Ballast water carried in any tank containing a residue of oil, NLSs, or any other pollutant must be discharged in accordance with the applicable regulations. Nothing in this subpart affects or supersedes any requirement or prohibitions pertaining to the discharge of ballast water into the waters of the United States under the Federal Water Pollution Control Act (33 U.S.C. 1251 et seq.).
(d) Unless otherwise expressly provided for in this subpart, the master, owner, operator, agent, or person in charge of vessels employing a Coast Guard-approved BWMS must meet the applicable ballast water discharge standard, found in § 151.1511 of this subpart, at all times of ballast water discharge into the waters of the United States.
