Start Preamble


Coast Guard, DHS.


Final rule.


The Coast Guard is establishing a safety zone around the Perdido Regional Host (PRH), a high-production, manned oil and natural gas platform. The platform needs to be protected from vessels operating outside the normal shipping channels and fairways. Placing a safety zone around the platform will significantly reduce the threat of allisions, oil spills, and releases of natural gas, and thereby protect the safety of life, property, and the environment.


This rule is effective November 27, 2009.

Regulatory Information

On February 13, 2009, we published an interim rule with a request for comments entitled, “Safety Zone; Perdido Regional Host Outer Continental Shelf Platform in the Gulf of Mexico” in the Federal Register (74 FR 7181). We received no comments on the interim rule.

Background and Purpose

The safety zone established by this regulation is in the deepwater area of the Gulf of Mexico, located at 26°07′44″ N, 094°53′53″ W in Alaminos Canyon block 857. For the purposes of this regulation, the deepwater area is considered to be waters of 304.8 meters (1,000 feet) or greater depth extending to the limits of the Exclusive Economic Zone (EEZ), which is contiguous to the territorial sea of the United States, and extends up to 200 nautical miles from the baseline from which the breadth of the territorial sea is measured. Navigation in the area of the safety zone consists of large commercial shipping vessels, fishing vessels, cruise ships, tugs with tows and the occasional recreational vessel. The deepwater area also includes an extensive system of fairways.

Shell Offshore, Inc. requested that the Coast Guard establish a safety zone around the Perdido Regional Host. The request for the safety zone was made due to the safety concerns for both the personnel aboard the platforms and the environment. Shell Offshore, Inc. indicated that the location, production level, and personnel levels on board the platform makes it highly likely that any allision with the platform would result in a catastrophic event. Perdido Regional Host is a high production oil and gas drilling platform producing approximately 100,000 barrels of oil per day and 200 million standard cubic feet of gas per day; it is manned with a crew of approximately 150 people.

In evaluating this request, the Coast Guard explored relevant safety factors and considered several criteria, including but not limited to: (1) The level of shipping activity around the facility; (2) safety concerns for personnel aboard the facility; (3) concerns for the environment; (4) the likeliness that an allision would result in a catastrophic event based on proximity to shipping fairways, offloading operations, production levels, and size of the crew; (5) the volume of traffic in the vicinity of the proposed area; (6) the types of vessels navigating in the vicinity of the proposed area; and, (7) the structural configuration of the facility.

Results from a thorough and comprehensive examination of the criteria, IMO guidelines, and existing regulations warrant the establishment of a safety zone of 500 meters around Perdido Regional Host at 26°07′44″ N, 094°53′53″ W.

Discussion of Comments and Changes

We received no comments in response to the interim rule.

Regulatory Analyses

We developed this rule after considering numerous statutes and executive orders related to rulemaking. Below we summarize our analyses based on 13 of these statutes or executive orders.

Regulatory Planning and Review

This rule is not a significant regulatory action under section 3(f) of Executive Order 12866, Regulatory Planning and Review, and does not require an assessment of potential costs and benefits under section 6(a)(3) of that Order. The Office of Management and Budget has not reviewed it under that Order.

This rule is not a significant regulatory action due to the distance of the Perdido Regional Host from both land and safety fairways. Vessels traversing waters near the safety zone will be able to safely travel around the zone without incurring additional cost.

Small Entities

Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have considered whether this rule would have a significant economic impact on a substantial number of small entities. The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000.

The Coast Guard certifies under 5 U.S.C. 605(b) that this rule will not have a significant economic impact on a substantial number of small entities.

This rule will affect the following entities, some of which may be small entities: The owners or operators of vessels intending to transit or anchor in Alaminos Canyon block 857. This safety zone will not have a significant economic impact on a substantial number of small entities for the following reasons: (1) This rule will enforce a safety zone around a production platform that is in an area of the Gulf of Mexico not typically frequented by vessel traffic; (2) this rule will enforce a safety zone that is not in close proximity to a safety fairway; and, (3) vessel traffic can pass safely around the safety zone without incurring additional costs.

Assistance for Small Entities

Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), in the interim rule we offered to assist small entities in understanding the rule so that they could better evaluate its effects on them and participate in the rulemaking process.

Small businesses may send comments on the actions of Federal employees who enforce, or otherwise determine compliance with, Federal regulations to the Small Business and Agriculture Regulatory Enforcement Ombudsman and the Regional Small Business Regulatory Fairness Boards. The Ombudsman evaluates these actions annually and rates each agency's responsiveness to small business. If you wish to comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR (1-888-734-3247). The Coast Guard will not retaliate against small entities that question or complain about this rule or any policy or action of the Coast Guard.

Collection of Information

This rule calls for no new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).


A rule has implications for federalism under Executive Order 13132, Federalism, if it has a substantial direct effect on State or local governments and would either preempt State law or impose a substantial direct cost of compliance on them. We have analyzed this rule under that Order and have determined that it does not have implications for federalism.Start Printed Page 55138

Unfunded Mandates Reform Act

The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 or more in any one year. Though this rule will not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble.

Taking of Private Property

This rule will not effect a taking of private property or otherwise have taking implications under Executive Order 12630, Governmental Actions and Interference with Constitutionally Protected Property Rights.

Civil Justice Reform

This rule meets applicable standards in sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, eliminate ambiguity, and reduce burden.

Protection of Children

We have analyzed this rule under Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks. This rule is not an economically significant rule and does not create an environmental risk to health or risk to safety that may disproportionately affect children.

Indian Tribal Governments

This rule does not have tribal implications under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, because it does not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.

Energy Effects

We have analyzed this rule under Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use. We have determined that it is not a “significant energy action” under that order because it is not a “significant regulatory action” under Executive Order 12866 and is not likely to have a significant adverse effect on the supply, distribution, or use of energy. The Administrator of the Office of Information and Regulatory Affairs has not designated it as a significant energy action. Therefore, it does not require a Statement of Energy Effects under Executive Order 13211.

Technical Standards

The National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note) directs agencies to use voluntary consensus standards in their regulatory activities unless the agency provides Congress, through the Office of Management and Budget, with an explanation of why using these standards would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., specifications of materials, performance, design, or operation; test methods; sampling procedures; and related management systems practices) that are developed or adopted by voluntary consensus standards bodies.

This rule does not use technical standards. Therefore, we did not consider the use of voluntary consensus standards.


We have analyzed this rule under Department of Homeland Security Management Directive 023-01 and Commandant Instruction M16475.lD, which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and have concluded this action is one of a category of actions which do not individually or cumulatively have a significant effect on the human environment. This rule is categorically excluded, under figure 2-1, paragraph (34)(g), of the Instruction, because the rule establishes a safety zone. An environmental analysis checklist and a categorical exclusion determination are will be available in the docket where indicated under ADDRESSES.
