153.203—Procedure for the notice of discharge.
Any person in charge of a vessel or of an onshore or offshore facility shall, as soon as they have knowledge of any discharge of oil or a hazardous substance from such vessel or facility in violation of section 311(b)(3) of the Act, immediately notify the National Response Center (NRC), U.S. Coast Guard, 2100 2nd St., SW., Stop 7238, Washington, DC 20593-7238, toll free telephone number: 800-424-8802, direct telephone: 202-267-2675, or Fax: 202-267-1322. If direct reporting to the NRC is not practicable, reports may be made to the Coast Guard or EPA predesignated OSC for the geographic area where the discharge occurs. All such reports shall be promptly relayed to the NRC. If it is not possible to notify the NRC or the predesignated OSC immediately, reports may be made immediately to the nearest Coast Guard unit, provided that the person in charge of the vessel or onshore or offshore facility notifies the NRC as soon as possible. A report made under this section satisfies the reporting requirements of § 151.15 of this chapter and of 46 CFR 4.05-1, if required under that provision.
