Definitions

The following definitions are of terms we may use during the Port Access Routes Study (PARS). We include them here for those who are unfamiliar with these terms and their abbreviations.

Area to be avoided (ATBA) means a routing measure comprising an area within defined limits in which either navigation is particularly hazardous or it is exceptionally important to avoid casualties and which should be avoided by all ships, or certain classes of ships.

Deep-water route is a route within defined limits, which has been accurately surveyed for clearance of sea bottom and submerged obstacles as indicated on nautical charts.

Inshore traffic zone is a routing measure comprising a designated area between the landward boundary of a traffic separation scheme and the adjacent coast, to be used in accordance with the provisions of Rule 10(d), as amended, of the International Regulations for Preventing Collisions at Sea, 1972 (COLREGS).

Precautionary area means a routing measure comprising an area within defined limits where ships must navigate with particular caution and within which the direction of traffic flow may be recommended.

Recommended route means a route of undefined width, for the convenience of ships in transit, which is often marked by centerline buoys.

Recommended track is a route which has been specifically examined to ensure so far as possible that it is free of dangers and along which ships are advised to navigate.

Regulated navigation area (RNA) is a water area within a defined boundary for which regulations for vessels navigating within the area have been established under 33 CFR part 165.

Roundabout is a routing measure comprising a separation point or circular separation zone and a circular traffic lane within defined limits. Traffic within the roundabout is separated by Start Printed Page 48838moving in a counterclockwise direction around the separation point or zone.

Separation zone or separation line means a zone or line separating the traffic lanes in which ships are proceeding in opposite or nearly opposite directions; or from the adjacent sea area; or separating traffic lanes designated for particular classes of ships proceeding in the same direction.

Traffic lane means an area within defined limits in which one-way traffic is established. Natural obstacles, including those forming separation zones, may constitute a boundary.

Traffic separation scheme (TSS) means a routing measure aimed at the separation of opposing streams of traffic by appropriate means and by the establishment of traffic lanes.

Two-way route is a route within defined limits inside which two-way traffic is established, aimed at providing safe passage of ships through waters where navigation is difficult or dangerous.

Vessel routing system means any system of one or more routes or routing measures aimed at reducing the risk of casualties; it includes traffic separation schemes, two-way routes, recommended tracks, areas to be avoided, inshore traffic zones, roundabouts, precautionary areas, and deep-water routes.

Background and Purpose

Port Access Route Study Requirements. Under the Ports and Waterways Safety Act (PWSA)(33 U.S.C. 1223(c)), the Secretary of Transportation may designate necessary fairways and TSS's to provide safe access routes for vessels proceeding to and from U.S. ports. The Secretary's authority to make these designations was delegated to the Commandant, U.S. Coast Guard, in title 49 of the Code of Federal Regulations, 49 CFR 1.46. The designation of fairways and TSS's recognizes the paramount right of navigation over all other uses in the designated areas.

The PWSA requires the Coast Guard to conduct a study of port access routes before establishing or adjusting fairways or TSS's. Through the study process, we must coordinate with Federal, State, and foreign state agencies (as appropriate) and consider the views of maritime community representatives, environmental groups, and other interested stakeholders. A primary purpose of this coordination is, to the extent practicable, to reconcile the need for safe access routes with other reasonable waterway uses.

Port access route study. The approaches to the Chesapeake Bay, VA, were last studied in 1989, and the final results were published in the Federal Register on July 13, 1989 (54 FR 29627). The study primarily examined the Southern Approach to Chesapeake Bay to accommodate vessels requiring a deep-water route. The PARS concluded that the existing Eastern Approach and Precautionary Area should remain unchanged, and it proposed the creation of the current deep-water route of the Southern Approach. A final rule, entitled “Traffic Separation Scheme; In The Approaches to Cheasapeake Bay” was published April 28, 1994 (59 FR 21935).

Why is a new port access route study necessary? Recent National Oceanic and Atmospheric Administration (NOAA) hydrographic data from a survey conducted April 12-17, 2001, indicate that Nautilus Shoal, bordering the northern edge of the Eastern Approach to Chesapeake Bay, is slowly moving southward and is encroaching the inbound traffic lane, which is limiting the use of this traffic lane to those vessels with drafts less than 27 feet (8.2 meters). This slow, continuous southward movement of Nautilus Shoal has spawned the need to evaluate the current location of the Eastern Approach and to determine if there is a different location that will better accommodate vessels that use this route to access Chesapeake Bay.

Based on potential changes to the Eastern Approach, it requires us to also study the Southern Approach to Chesapeake Bay. Therefore, we will study all the data concerning vessel movements in the Southern Approach to determine if modifications are needed for this approach as well.

Timeline, study area, and process of this PARS. The Fifth Coast Guard District will conduct this PARS to determine the need to modify existing routing measures and the effects of potential modifications in the study area. The study will begin immediately and we anticipate the study will take 6 to 12 months to complete.

The study area will encompass the area bounded by a line connecting the following geographic points (All coordinates are NAD 1983):

LatitudeLongitude
37°00.00′ N075°56.00′ W
37°00.00′ N075°40.00′ W
36°45.00′ N075°40.00′ W
36°45.00′ N075°56.00′ W

The study area encompasses the Eastern and Southern approaches to Chesapeake Bay used by commercial and public vessels.

As part of this study, we will consider previous studies, analyses of vessel traffic density, and agency and stakeholder experience in vessel traffic management, navigation, ship handling, and affects of weather. We encourage you to participate in the study process by submitting comments in response to this notice.

We will publish the results of the PARS in the Federal Register. It is possible that the study may validate continued applicability of existing vessel routing measures and conclude that no changes are necessary. It is also possible that the study may recommend one or more changes to enhance navigational safety and vessel traffic management efficiency. Study recommendations may lead to future rulemakings or appropriate international agreements.

Potential Study Recommendations

We are attempting to determine the scope of any safety problems associated with vessel transits in the study area. We expect that information gathered during the study will identify any problems and appropriate solutions. The study may recommend that we—

  • Maintain the current vessel routing measures;
  • Disestablish the Eastern Approach TSS;
  • Relocate the Eastern Approach TSS to the south of its current location;
  • Modify the Southern Approach as necessary;
  • Establish an Area to Be Avoided (ATBA) in shallow areas where the risk of grounding is present;
  • Disestablish Chesapeake Light; and
  • Replace Chesapeake Light with a lighted buoy or a smaller structure.
