Privacy Act Statement

Pursuant to 5 U.S.C §552a(e)(3), this Privacy Act Statement serves to inform you of why DHS is requesting the information on this form.

AUTHORITY: 14 U.S.C. § 500; 46 USC § 70041; and 33 CFR § 100.15.

PURPOSE: The Coast Guard will use this information to determine whether a marine event poses an extra or unusual hazard to the safety of life and whether or not, and under which conditions, to permit the event on the navigable waters of the United States.

ROUTINE USES: Authorized USCG personnel will use this information to evaluate the marine event request.  Any external disclosures of information with this record will be made in accordance with DHS/USCG-013.  Marine Information for Safety and Law Enforcement (MISLE), 74 Federal Register 30305 (June 25, 2009).

CONSEQUENCES OF FAILURE TO PROVIDE INFORMATION: Furnishing this information is strictly voluntary.  However, failure to provide this information may delay or prevent the approval of the marine event.


An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a valid OMB control number.  The Coast Guard estimates that the average burden for this report is 60 minutes.  You may submit any comments concerning the accuracy of this burden estimate or any suggestion for reducing the burden to:  United States Coast Guard, Commandant (CG-WWM-1) Stop 7509, 2703 Martin Luther King Jr. Ave SE, Washington, DC. 20593-7509 or Office of Management and Budget, Paperwork Reduction Project (1625-0008), Washington, DC 20593.


FORM INSTRUCTIONS

  1. This application must reach the appropriate USCG Sector at least 135 days prior to the event.  However, the application may be submitted 60 days prior to the event if:
    (1) the sponsor held the same event last year,
    (2) the nature, location, date, time, and other relevant information contained in last year’s application is essentially the same,
    (3) the Coast Guard received no public objection to last year’s application, and
    (4) the Coast Guard approved last year’s event.
    Regardless of whether or not an event has received a permit in the past, sponsors are required to submit a marine event application to the Coast Guard for review. Because the late submission of applications may not allow us enough time to properly review and advertise your request, late applications may not be approved.
