 compounds and other air contaminants. The CAA requires states to adopt State Implementation Plans, or “SIPs,” some of which regulate emissions resulting from vessel loading and unloading operations which may affect our vessels.
The U.S. Clean Water Act (“CWA”) prohibits the discharge of oil, hazardous substances and ballast water in U.S. navigable waters unless authorized by a duly issued permit or exemption, and imposes strict liability in the form of penalties for any unauthorized discharges. The CWA also imposes substantial liability for the costs of removal, remediation and damages and complements the remedies available under OPA and CERCLA. In 2015, the EPA expanded the definition of “waters of the United States” (“WOTUS”), thereby expanding federal authority under the CWA. On December 30, 2022, the EPA and U.S. Army Corps of Engineers announced the revised WOTUS rule, which was published on January 18, 2023. In August 2023, the EPA and Department of the Army issued a final rule to amend the revised WOTUS definition to conform the definition of WOTUS to the U.S. Supreme Court’s interpretation of the Clean Water Act in its decision dated May 25, 2023. The final rule became effective September 8, 2023 and operates to limit the Clean Water Act.
The EPA and the USCG have also enacted rules relating to ballast water discharge, compliance with which requires the installation of equipment on our vessels to treat ballast water before it is discharged or the implementation of other port facility disposal arrangements or procedures at potentially substantial costs, and/or otherwise restrict our vessels from entering U.S. Waters. The EPA will regulate these ballast water discharges and other discharges incidental to the normal operation of certain vessels within United States waters pursuant to the Vessel Incidental Discharge Act (“VIDA”), which was signed into law on December 4, 2018 and requires that the U.S. Coast Guard develop implementation, compliance, and enforcement regulations regarding ballast water. On October 26, 2020, the EPA published a Notice of Proposed rulemaking for Vessel Incidental Discharge National Standards of Performance under VIDA, and in November 2020, held virtual public meetings On October 18, 2023, the EPA published a Supplemental Notice to the Vessel Incidental Discharge National Standards of Performance, which shares new ballast water information that the EPA received from the USCG.
