II. Background and Purpose

The Coast Guard announced in the Federal Register (76 FR 27288, May 11, 2011) that it was conducting a Port Access Route Study (PARS) to evaluate the continued applicability of, and the need for modifications to, current vessel routing measures or the creation of new routing measures off the Atlantic Coast from Maine to Florida. The impetus for the study was the Department of Interior's launch of the “Smart from the Start” renewable energy initiative that began with planning for wind development off the Atlantic Coast. The original comment period closed on August 9, 2011. A second comment period was announced to gather additional information and closed January 31, 2012. The initial announcement contains definitions and useful background information concerning the PARS. The public is encouraged to review the initial announcement.

The data gathered during the Atlantic Coast Port Access Route Study (ACPARS) may result in establishment of one or more new vessel routing measures, modification of existing routing measures, or disestablishment of existing routing measures off the Atlantic Coast from Maine to Florida. The goal of the ACPARS is to maintain or enhance navigational safety by examining existing shipping routes and waterway uses, and, to the extent practicable, reconcile the paramount right of navigation within designated port access routes with other reasonable waterway uses such as the leasing of outer continental shelf blocks for the construction and operation of offshore renewable energy facilities. The recommendations of the study may lead to future rulemaking action or appropriate international agreements.

The Coast Guard established the Atlantic Coast Port Access Route Study Workgroup to carry out the study and also coordinate efforts to support Coast Guard participation as a Cooperating Agency in the Bureau of Ocean Energy Management's efforts to identify priority areas for wind development.

The progress of the WG to date, as well as what remains to be accomplished have been compiled in an interim report dated July 13, 2012. The ACPARS Interim Report is being made available to the public through this Federal Register notice. The report will be available on the Federal Register docket and also on the ACPARS Web site at

III. ACPARS Interim Report—Executive Summary

The Atlantic Coast Port Access Route Study Workgroup (WG) was chartered on 11 May 2011, and was given three objectives to complete within the limits of available resources: (1) Determine whether the Coast Guard should initiate actions to modify or create safety fairways, Traffic Separation Schemes (TSSs) or other routing measures; (2) Provide data, tools and/or methodology to assist in future determinations of waterways suitability for proposed projects; and (3) Develop, in the near term, Automated Identification System (AIS) products and provide other support as necessary to assist Districts with all emerging coastal and offshore energy projects. The WG has conducted public and stakeholder outreach including two public comment periods advertised in the Federal Register. The WG has faced challenges in the lack of Coast Guard (CG) capability to fully analyze AIS data and in identifying funding to perform modeling and analysis. This resulted in an inability to predict changes in traffic patterns or determine the resultant change in navigational safety risk given different siting scenarios of offshore renewable energy installations. However, the WG has developed a methodology for initially classifying lease blocks as: not suitable (Red), may be suitable with more study (Yellow) or suitable (Green), based on proximity to shipping routes. This methodology has been used by the CG to provide input to the Bureau of Ocean Energy Management (BOEM) regarding the potential impact to navigation of areas being proposed for wind energy development. The WG has determined, given the lack of complete AIS data and rudimentary analysis to date, that recommending even preliminary routing measures is not appropriate at this time. The WG has concluded that modeling and analysis, as described in the Phase 3 of the ACPARS interim report, is critical to determine if routing measures are appropriate and to evaluate the change in navigational safety risk resulting from different siting and routing scenarios. The CG is working with BOEM to develop a project to perform the Phase 3 modeling and analysis. This project is scheduled to begin in late summer 2012. The Coast Guard is also contracting the services of a Geographic Information System (GIS) analyst to support efforts to better characterize vessel traffic and further explore creating initial proposals for routing measures independent of the Phase 3 modeling and analysis.

This notice is issued under authority of 33 U.S.C. 1223(c) and 5 U.S.C. 552.
