Proposed rule; request for comments.


NMFS proposes to clarify the definition of length overall (LOA) of a vessel. This would provide unambiguous guidance to vessel owners in determining a vessel's LOA for purposes of Federal fisheries management programs and to facilitate NMFS’ and the U.S. Coast Guard’s (USCG) enforcement of LOA requirements in the exclusive economic zone (EEZ) off Alaska. The action is intended to further the goals and objectives of the Fishery Management Plan (FMP) for Groundfish of the Gulf of Alaska and the FMP for the Groundfish Fishery of the Bering Sea and Aleutian Islands Area.

The domestic groundfish fisheries in the EEZ off Alaska are managed by NMFS under the FMPs. The FMPs were prepared by the North Pacific Fishery Management Council (Council) under the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act). Regulations governing the Alaska groundfish fisheries appear at 50 CFR parts 600 and 679. This proposed action would clarify the definition of vessel LOA, remove the definitions of stem and stern, and add a definition for bulwarks. -

Presently, the definition of LOA requires measurement from the “foremost part of the stem” to the “aftermost part of the stern.” As illustrated by Figure 6 of 50 CFR part 679, this definition is intended to be an end-to-end measurement of the vessel and implicitly include the bulwarks of a vessel. For purposes of commercial fishing in the EEZ off Alaska, vessel LOA was first defined by the final rule implementing the observer program (55 FR 4839, February 12, 1990). Figure 6 was added to 50 CFR part 679 by a subsequent interpretive rule and technical amendment (57 FR 43621, September 22, 1992) that intended to clarify that definition. Although NMFS does not explicitly mention the term “bulwarks” in that interpretive rule/technical amendment, the preamble to the rule provides a technical description and interpretation of the term “stem” as “the foremost position of the vessel, a section of timber or cast, forged, or rolled metal to which the sides of a vessel are united at the fore end” (57 FR 43622). The illustration amended to the regulations as Figure 6 clearly depicts the inclusion of bulwarks in LOA measurement. NMFS intended the interpretative language and the illustration of Figure 6 to clarify the definition of LOA to include bulwarks. Moreover, NMFS enforcement policy has always included in any LOA measurement bulwarks that constitute the foremost or aftermost part of a vessel. -

NMFS recognizes now that the definition of LOA still requires clarification. Despite the visual representation of bulwarks as part of the LOA in Figure 6, the language of the former interpretative rule is overly technical and the terms “stem” and “stern” remain open to misinterpretation. This action would remove “stem” and “stern” from the definition of LOA, add the term “bulwarks,” and thus clarify the original intent of the regulation that LOA measurement be an end-to-end measurement of a vessel. -

Maritime regulations of other Federal agencies such as the USCG often use similar terminology to define LOA. However, the terms “foremost part of the stem” and “aftermost part of the stern” may or may not implicitly include bulwarks in the definition of overall vessel LOA. Federal regulators Start Printed Page 28884define LOA differently for different purposes. For instance, USCG regulations at 46 CFR 69.203 use LOA to categorize vessels by buoyant hull volume, which cannot include structures such as bulwarks that are open to the weather and thus constitute no part of a vessel’s buoyant hull envelope. These two different uses of the terms “foremost part of the stem” and “aftermost part of the stern” create the potential for confusion and inconsistent application of the LOA measurement by the regulated public. -

For purposes of managing fisheries, vessel LOA provides NMFS with one criterion by which to categorize and manage the diverse capacities and capabilities of fishing vessels operating in Federal waters off Alaska. Distinguishing vessels by LOA categories allows NMFS to assign harvesting privileges in ways that ensure that fishing fleets remain relatively diversified between larger and smaller vessels and prevent over-consolidation of fishing privileges among any one sector of the fisheries, as well as to manage the growth of harvest capacity in a fishery and protect the historical character of a fishery and its dependent communities. -

LOA categories also allow NMFS to assess the relative ability of fishermen to afford the cost of certain regulatory requirements, such as those requiring observer coverage. -

Moreover, NMFS enforcement officers and USCG personnel charged with monitoring the fisheries for compliance with regulations require a practical definition of LOA that will facilitate the measurement of LOA. Despite the difficulty of measuring LOA during fishing operations, enforcement officers do take such measurements at dockside or at sea to ensure a vessel’s compliance with regulatory requirements, such as observer coverage requirements. Bulwarks are a clearly visible part of a vessel’s size; as such, including them in LOA measurement would make a vessel’s length easier to ascertain from dockside or while the vessel is at sea. -

For these reasons, NMFS proposes to revise the definition of LOA to explicitly include bulwarks, remove the definitions of “stem” and “stern,” and add a definition of “bulwark” to the definitions in 50 CFR 679.2. This action would not require a vessel owner to change the recorded LOAs of a vessel already registered with NMFS, provided the vessel’s LOA accurately reflects the vessel’s end-to-end measurement as shown in Figure 6 of 50 CFR part 679. This figure accurately depicts the end-points of LOA measurement. This action would prevent future misinterpretation of the regulatory definition of LOA. -


This proposed rule has been determined to be not significant for purposes of Executive Order 12866. -

NMFS prepared an IRFA that analyzes the potential impact of this proposed action on small entities for purposes of the Regulatory Flexibility Act. While this action is intended simply to clarify the existing definition of LOA and thus prevent any misunderstanding or equivocation by vessel owners in determining a vessel’s LOA. Some of the 1,613 vessels currently operating in the EEZ off Alaska under Federal Fisheries Permits may find their registered LOAs to be inconsistent with the regulatory definition of LOA. Vessels failing to have correct LOA measurements may incur costs associated with remeasuring their LOA. Unfortunately, at this time, NMFS has insufficient data to assess the actual number of such vessels affected in this manner, but it believes most LOAs are accurate. -

However, vessels that are near observer coverage thresholds, (125 ft or 60 ft, as applicable) may incur considerable cost if it is determined that their LOA is incorrect and that they should actually be subject to a higher level of observer coverage. Approximately 38 vessels with recorded LOA measurements of 124, 123,and 122 ft may be subject to more stringent observer requirements if their LOAs are actually 125 ft or greater. Approximately 156 vessels with LOA measurements of 57, 58, and 59 ft may be subject to more stringent observer requirements if their LOAs are actually 60 ft or greater. Such vessels could incur costs of $300/day for an observer.
