Coast Guard, DHS.
Notice of proposed rulemaking.
The Coast Guard proposes to amend its regulations for commercial diving that is conducted from deepwater ports or deepwater port safety zones, or in connection with Outer Continental Shelf (OCS) activities, or from vessels that are required to have a Coast Guard certificate of inspection. The regulations would be revised and updated to improve safety and to reflect current industry best practices. The proposed regulations would also allow the Coast Guard to approve independent third-party organizations to assist with ensuring regulatory compliance of commercial diving regulations. The proposed amendments promote the Coast Guard's maritime safety mission.

III. Basis and Purpose
The legal basis for this notice of proposed rulemaking (NPRM) is 33 U.S.C. 1509(b), which requires safety regulations for deepwater ports; 43 U.S.C. 1333(d)(1), which permits safety regulations for Outer Continental Shelf (OCS) facilities and their equipment; 46 U.S.C. 3306, which requires regulations to implement subtitle II of Title 46 of the U.S. Code with respect to inspected vessels, including offshore supply vessels and their equipment; 46 U.S.C. 3703, which requires safety and environmental protection regulations for liquid bulk dangerous cargo carriers and their equipment, to be issued after consultation with Federal, State, and local governments and with private sector entities (we specifically request interested government agencies and private sector entities to comment on this NPRM); and 46 U.S.C. 6101, which requires regulations for reporting and investigating marine casualties. The Secretary of Homeland Security's authority under all of these statutes has been delegated to the Commandant of the Coast Guard by Department of Homeland Security Delegation No. 0170.1, para. II (75), (90), and (92).
The purpose of the NPRM is to propose revisions and updates to our existing commercial diving regulations, to improve safety, to reflect current industry best practices, and to facilitate the use of approved third-party organizations to ensure regulatory compliance.
History. The Coast Guard issued commercial diving operation regulations (found at 46 CFR part 197, subpart B), in 1978. Generally, the regulations apply to commercial operations conducted from deepwater ports (such as offshore liquefied natural gas facilities), or as a part of OCS activities, or from vessels that are required to have a Coast Guard certificate of inspection.
Commercial diving operations conducted near shore or in U.S. internal waters from a vessel not required to have a Coast Guard certificate of inspection are not covered by Coast Guard regulations, but are regulated by the Occupational Safety and Health Administration (OSHA).
We began this rulemaking in 1994 at the request of an industry group now known as the Association of Diving Contractors International (ADCI). Among other recommendations for updating our 1978 regulations, ADCI suggested the Coast Guard incorporate its consensus standards into regulation. We issued our first advance notice of proposed rulemaking (ANPRM) in 1998 
and noted that our regulations were then already 20 years old and did not reflect the latest safety and technology standards and industry best practices. In 2009, a second ANPRM 
discussed in detail the public comments we received for the 1998 ANPRM, recounted the early history of the rulemaking, and summarized developments between 1998 and 2009. The public comments received on the 1998 ANPRM revealed a deep split of opinion as to which industry group's standards should be incorporated in our regulations. Our position in the 2009 ANPRM was to encourage continued industry interest in this rulemaking and to solicit a new round of public comments.
Recommendations to the Coast Guard. We are aware of continuing issues such as proper dive manning, drill, medical and audit practices/requirements among others, that have continued to be evident in the industry. Consequently, in this NPRM, we propose a complete revision of the commercial diving operation regulations in 46 CFR part 197, subpart B. In doing so, we are mindful of the recommendations made in the Coast Guard's 1996 formal investigation report into a commercial diving fatality involving Cliff's Drilling Rig No. 12 (“the Rig 12 report”), and of recommendations made in 2008 and 2012 by the Diving Subcommittee of the National Offshore Safety Advisory Committee (“the NOSAC report”). (NOSAC is a Federal advisory committee that advises the Coast Guard on matters related to operations and safety on the OCS.) All recommendations in the reports discussed above are available in the online docket at http://www.regulations.gov.
The Rig 12 report recommended new requirements for additional safety equipment, standby divers, equipment maintenance records, and pre-dive planning. This NPRM proposes many of these measures. The Rig 12 report also recommended against delegating Coast Guard dive safety enforcement duties to third-parties. Although this NPRM proposes the use of independent third-party auditors, their proposed use is intended to leverage industry expertise and capabilities, and provide a framework for Coast Guard enforcement, not to relieve us of our regulatory responsibilities. Therefore, we do not regard the use of third-party organizations as being contrary to the Rig 12 report recommendation.
The 2008 NOSAC report to the Coast Guard 
noted that two industry groups, ADCI and the International Marine Contractors Association, had published standards that were more up to date than our regulations. The 2008 NOSAC report's major recommendations included avoiding overly-prescriptive requirements that might stifle innovation in diving safety, developing specific requirements for each diving mode, and setting training requirements that balance practical experience with classroom instruction. To implement those major recommendations, we concluded that it would be better to completely revise our regulations instead of making the section-by-section changes NOSAC suggested.
The 2008 NOSAC report found that audits would be “of great benefit” but “should be developed, implemented, and performed by industry in order to ensure full consideration of the operation in that geographical area.” We encourage industry to conduct its own audits, this NPRM proposes the use of Coast Guard-approved third-party organizations subject to Coast Guard approval and oversight. In determining whether to approve a third-party organization, we would take into account the organization's ability to understand operating conditions within specific geographical areas.
NOSAC also recommended in 2008 against recognizing self-contained underwater breathing apparatus (SCUBA) diving as an offshore commercial diving application. However, our discussions with members of the commercial diving industry and knowledge of known commercial diving activities indicates that this mode of diving continues to be used in some commercial diving operations, especially in shallow water. Since we are aware that SCUBA continues to be used in commercial diving activities regulated by the Coast Guard, we believe SCUBA diving should continue to be addressed in our commercial diving regulations in order to maintain established minimum safety standards for that mode of diving.
In November 2009, NOSAC issued a report to the Coast Guard voicing concerns about the evacuation and medical treatment of injured workers from remote OCS facilities. Recognizing the importance of this matter, we asked NOSAC to reestablish the subcommittee Start Printed Page 9154on commercial diving operations to review and assess the various issues and challenges associated with providing timely medical attention and treatment to divers who become ill or are injured while working subsea/under pressures at remote OCS facilities or from the vessels servicing them. We asked the subcommittee to review and assess present capabilities, practices, and procedures for medical treatments and evacuations for injured divers to shore treatment facilities from offshore facilities, including industry and government agency resources and capabilities. We also asked the subcommittee to prepare a final report for NOSAC's review and approval, recommending how to alleviate the issues and problems associated with medical treatment or evacuation of injured divers from remote OCS facilities. On May 8, 2012, NOSAC made their final report to us, containing the following recommendations concerning commercial diving operations:
1. Require a certified diver medical technician on each surface-supplied and saturation diving operation taking place on the Outer Continental Shelf in the Gulf of Mexico;
2. Ensure that the certified diver medical technician in a saturation diving operation shall have saturation diving certification and experience;
3. Ensure that the certified diver medical technician in a surface diving operation shall have surface diving certification and experience; and
4. Ensure a detailed emergency action plan is in place for medical trauma or barotrauma related injuries for each diving operation. Environmental parameters, equipment, personnel, onboard medical supplies for remote operations and logistics should also be considered.
Our NPRM addresses these recommendations, except that we believe that certified diver medical technicians may only be necessary for saturated diving operations, which would be in keeping with current U.S. industry practices. Presently, the commercial diving industry is required to have at least one diver medical technician on all saturation diving projects, in accordance with the 6th edition of the Association of Diving Contractors, “International Standards for Commercial Diving and Underwater Operations.” Additionally, as part of adopting this industry standard for saturated diving operations, we would require an emergency evacuation system to help ensure that divers undergoing hyperbaric treatment can be safely removed in the event of an emergency.
V. Discussion of Comments on 2009 ANPRM
Comments received during the public comment period. The 2009 ANPRM specifically requested comment on six topics: (1) the possible regulatory adoption of industry standards, (2) the use of third-party organizations (TPOs) to conduct regulatory compliance audits, (3) compliance documentation, (4) recommendations made by the Rig 12 report, (5) regulatory priorities, and (6) regulatory costs and benefits. We received comments from seven individuals or associations during the public comment period and, for the most part, the seven did not explicitly address the six topics we requested.
One commenter asked if certain other organizations had posted comments and, if so, how to view their comments. Only one of the organizations mentioned by this commenter submitted a comment and it had already been posted online at http://www.regulations.gov. A second commenter asked the Coast Guard to regulate SCUBA diving for the commercial harvesting of coral in Hawaii. Coral harvesting is a form of commercial fishing and, as such, it is not covered by either our current or our proposed regulations, except when conducted from a Coast Guard-inspected vessel (most commercial fishing vessels are uninspected). Another commenter asked us to extend our commercial diving regulations to all marine assistance towing and salvage industry vessels. Proposals to extend the applicability of the commercial diving regulations to vessels or operations that are not now covered by those regulations are beyond the scope of this rulemaking.
The fourth commenter expressed support for the use of TPOs to help provide a consistent level of compliance auditing. We agree with this comment, and third-party auditing is a central concept of this NPRM.
The fifth commenter said that visual inspection of diver helmets is sufficient and that a requirement for annual helmet inspection only imposes unnecessary cost. Our review of commercial diving casualty data indicates that visual inspections are not enough to ensure that a helmet can be used safely in the hazardous conditions for which it is designed. We propose that helmets, as well as all other essential diving equipment, be inspected, maintained, and serviced in accordance with the manufacturer's instructions.
The sixth commenter, an association, noted its participation in developing NOSAC's 2008 recommendations for improving our commercial diving regulations, and confirmed its ongoing interest in improving safety and efficiency. This comment requires no substantive response.
The final commenter made 15 specific recommendations. In general, the recommendations dealt with safety equipment maintenance and repair guidelines and documentation, and with training requirements for safety equipment technicians and users. We believe our proposals align with the intent of those recommendations. The commenter also recommended specific reporting and chain of custody requirements for equipment involved in diving fatalities. In the event of a marine casualty or a serious marine incident, this NPRM proposes requiring the commercial diving operator (CDO) to suspend the commercial diving operation, take action to protect the safety of life and the environment, and resume the operation only after all commercial diving employees have fully complied with the reporting requirements of 46 CFR part 4. Additionally, the CDO would be required to analyze the event and take all reasonable action required to prevent further events from occurring, arrange for a timely post-casualty audit, and ensure that any equipment that may have contributed to the event is immediately removed from service and secured against unauthorized access and any change in its material condition. This NPRM also proposes requiring most diving equipment to carry a serial number or other unique identifier to aid in recording equipment maintenance and to facilitate casualty investigations. Finally, the commenter recommended standardizing training for Coast Guard regulatory compliance personnel. In lieu of standardizing training for Coast Guard regulatory compliance personnel, this NPRM would augment Coast Guard enforcement activities through the use of TPOs to provide another method for improving regulatory compliance. We invite the commenter to consider whether our NPRM proposals adequately address the concerns and to comment on those proposals.
Late comments. We also received six comments after the close of the public comment period.
The first late commenter said we should license all dive supervisors and life support technicians, that licensed supervisors and technicians should not be removed during diving operations except at their own request or for cause, and that we should make unannounced dive site inspections. We do not have authority to license commercial divers Start Printed Page 9155or dive support personnel at this time. However, in this NPRM, we propose requiring commercial diving personnel to have the knowledge, skills, experience, and certification necessary to perform their assigned duties. Many of the desirable outcomes of a Coast Guard licensing program would be provided for by completing the training and experience requirements defined in this NPRM. We would enforce compliance through documentation requirements, inspections, and third-party audits. This commenter also recommended United States and British coordination of dive personnel requirements. We believe our incorporation of the international dive standards of ADCI and of International Maritime Organization (IMO) Assembly Resolution A.831(19), the International Code of Safety for Diving Systems, meets the intent of the commenter.
The other late commenters all suggested minimum dive team size and composition requirements. This NPRM reflects many of those suggestions and we are interested in hearing from the public as to whether our proposed minimum requirements are appropriate.
VI. Discussion of Proposed Rule
We propose revising the 1978 commercial diving regulations in subpart B of 46 CFR part 197 (Marine Occupational Safety and Health Standards, General Provisions). The scope of diving operations affected by these regulations would not change, and affected diving operators would still be able to substitute alternative measures, standards, or equipment if those can be shown to provide an equivalent level of safety. However, we would replace most of the regulations that impose specific operational, personnel, and equipment requirements with new regulations that draw on industry's best practices incorporated in ADCI's current consensus standards. We would also incorporate ADCI's commercial diver training requirements which are based in part on the consensus standards of the Association of Commercial Diving Educators (ACDE). Our proposed regulatory language does not duplicate all the provisions of either the ADCI or ACDE standards, but instead adapts them to create a new regulatory baseline. Affected diving operations would have to comply with that baseline, but where they can use practices that provide greater safety than our baseline, we encourage them to voluntarily do so.
The 2009 ANPRM 
discussed our preference for using “regulations as a tool to encourage compliance, before injuries or deaths occur, rather than as a way of punishing violators in the wake of a tragedy.” Currently, the enforcement of commercial diving regulations is governed by the general civil and criminal penalty procedures found in 33 CFR subpart 1.07, and on the authority to initiate personnel actions against licensed mariners authorized under 46 CFR subchapter A (Procedures Applicable to the Public). We will retain these tools but believe they, alone, are inadequate to prevent accidents from happening. Therefore, this NPRM focuses on proactively promoting and supporting appropriate administrative, operational, and auditing environments to ensure or improve safety. Under our proposals, commercial diving operators would have to provide additional compliance documentation. Coast Guard personnel or approved TPOs would be authorized to inspect operator records, observe diving operations, and interview an operator's employees.
In some diving accidents, the dive team has been so small that it was unable to respond to the emergency or retrieve a disabled diver in time to avoid a serious injury or death. Often, a single dive team member holds multiple duties (for example serving as both the dive supervisor and as a standby diver). This NPRM proposes new minimum standards for the size and composition of dive teams. We also propose prohibiting standby divers from having multiple duties that could interfere with their ability to focus on their primary role or respond adequately to an emergency. These proposals are based on manning levels adopted by the ADCI and the International Association of Oil and Gas Producers. They are minimum levels for safe team operation in the emergency conditions that can readily arise in a dynamic operating environment.
We propose requiring U.S. inspected vessels conducting commercial diving operations in any waters and foreign vessels conducting diving operations on the U.S. Outer Continental Shelf to meet the IMO's International Code of Safety for Diving Systems.
This will help ensure that diving systems are designed, constructed, and surveyed in accordance with an accepted international standard. A diving system safety certificate would provide evidence of compliance. This certificate would be issued to a U.S. vessel by a recognized classification society; a foreign vessel's certificate would be issued by its flag state or their delegated authority.
Finally, we propose using TPOs to audit CDOs and determine, on our behalf, whether or not those CDOs are in compliance with our regulations. Our proposed use of TPOs to perform delegated regulatory oversight functions is similar to our longstanding use of recognized classification societies to perform delegated Coast Guard vessel inspection and certification functions, as described in 46 CFR part 8 subpart B. These arrangements enable the Coast Guard to make use of a commercial organization's trained personnel and resources. However, the Coast Guard specifically seeks public input on the following question: What merits and drawbacks can be associated with the proposed use of third parties acting on behalf of the Coast Guard to conduct audits of commercial diving operations?
Table 1 shows how the content of the current commercial diving regulations would be affected by this NPRM. Table 2 provides details about specific sections in the proposed regulations.

VII. Requests for Specific Comments
We would like more information about the SCUBA dive teams, whether all dive teams should include medical technicians, and whether or not we should consider alternative approaches to our proposed regulations. The following questions relate to these three issues. In response to these questions we ask for public comments with supporting data and references if possible.
SCUBA dive teams. Our first issue is the minimum size of a SCUBA dive team. Our NPRM proposes setting the minimum at four members, the same as required by the Army Corps of Engineers, but one more than OSHA's minimum.
QUESTION 1: The Coast Guard proposes a SCUBA dive team consisting of four members, based on the assumption that prudent commercial diving operators use SCUBA only when conditions are favorable to the diver and risk is minimal: That is, underwater visibility is greater than 3 feet, currents are less than 1 knot, and dive depth is no more than 100 fsw with no decompression. Is that assumption valid? Should a SCUBA dive team consist of more or fewer than four members? Why? What costs would be incurred and what benefits would be gained by setting the minimum higher or lower than four members?
Medical technicians. The second issue involves certified diving medical technicians (DMTs). Commercial diving exposes divers to unique risks and physical challenges, such as barotrauma, that may require specialized and readily available medical care.
QUESTION 2: Should a DMT always be available, either as part of the dive team or at the dive site during a dive? Why or why not? What costs would be incurred and what benefits would be gained by requiring this level of availability?
Alternative approaches. Our third issue involves alternative approaches.
QUESTION 3: Under one alternative to our proposals, the Coast Guard would not directly oversee TPO audits of commercial diving operations and would allow TPOs to self-certify that their audits comply with Coast Guard standards. However, we would indirectly oversee audits by investigating reported marine casualties and associated civil penalty proceedings. Under a second alternative, neither the Coast Guard nor a TPO would conduct inspections or audits of commercial diving operations. The only compliance oversight would come through casualty investigations and civil penalty proceedings.
The Coast Guard requests input on what merits and drawbacks may be associated with these two alternative approaches?

IX. Regulatory Analyses
We developed this proposed rule after considering numerous statutes and Executive Orders (E.O.s) related to rulemaking. Below we summarize our analyses based on these statutes or E.O.s.
A. Regulatory Planning and Review
E.O.s 12866 (“Regulatory Planning and Review”) and 13563 (“Improving Regulation and Regulatory Review”) direct agencies to assess the costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). Executive Order 13563 emphasizes the importance of quantifying both costs and benefits, of reducing costs, of harmonizing rules, and of promoting flexibility.
This proposed rule is not a significant regulatory action under section 3(f) of Executive Order 12866, Regulatory Planning and Review, as supplemented by Executive Order 13563, Improving Regulation and Regulatory Review. The Office of Management and Budget (OMB) has not reviewed it under that Order. Nonetheless, we developed an analysis of the costs and benefits of the proposed rule to ascertain its probable impacts on industry. We consider all estimates and analysis in this Regulatory Analysis (RA) to be preliminary and subject to change in consideration of public comments. A draft Regulatory Analysis including a draft preliminary Initial Regulatory Flexibility Analysis (IRFA) is available in the docket where indicated under the “Public Participation and Request for Comments” section of this preamble. A summary of the preliminary Regulatory Analysis and Initial Regulatory Flexibility Analysis follows. Our preliminary RA provides an evaluation of the impacts associated with this proposed rule. Table 3 below provides a summary of the affected population, costs, and benefits of the proposed rule.
Table 3—Summary of the Affected Population, Costs and Benefits of the NPRM
|Applicability||Diving undertaken in connection with commercial operations conducted from deepwater ports (such as offshore liquefied natural gas facilities), or OCS activities, or from vessels that are required to have a Coast Guard certificate of inspection; 46 CFR 197.200.|
|Affected Population||87 owners or operators of commercial diving operations (mainly heavy offshore marine construction or working from USCG-certificated vessels). 12 TPOs.|
|Costs ($, 7 percent discount rate)||Annualized: Manning: $1,460,500.
| ||10-Year: Manning: $14,606,000.
|Benefits ($, 7 percent discount rate)||Monetized Benefits from Manning Requirement
Injuries: $116, 935.
|Start Printed Page 9160|
| ||10-Year: Fatalities: $23,660,000.
Annualized Net Benefits: $1,056,000.|
| ||Benefits attributable to other requirements cannot be quantified easily since they intersect with all improvements.|
| ||Breakeven analysis on other rule items yields anywhere from 1 fatality per 44 years to 1 fatality every 3,056 years to breakeven.8|
| ||Sets one industry standard, and provides Coast Guard with additional inspection options to implement commercial diving operations.|
The purpose of this proposed rule is to save lives by revising and updating our existing commercial diving regulations to reflect current industry best practices.
Agencies take regulatory action for several reasons, one being the failure of markets to reach the socially optimal outcome. This can occur when there are economic incentives lacking for industry to pursue that outcome and such market failures are the impetus for this proposed rule. A negative externality is the by-product of a transaction between two parties that is not accounted for in the transaction. Vessels that operate with lower safety standards may cause harm or increased risk of harm without accounting for the consequences to third parties, who do not directly participate in the business transactions of the business entities such as merchant seaman. These costs are not borne by the responsible entities and are therefore external to the business decisions of the responsible entity.
The casualties resulting from commercial diving accidents are an example. The cost of the higher safety standards is typically borne by the vessel owner while the cost of an accident could be distributed across various entities, including the vessel owner, other vessel owners, related maritime businesses and commercial diver teams. These costs can be in the form of injuries and death.
The material failure of the private market increases the risk to other parties. There exists an uncompensated increase in risk due to potentially inconsistent safety practices in the commercial diving industry. Consequently, regulatory action is required to spur the industry to take action to reduce risk industry-wide and therefore attain the socially optimal outcome.
The functional benefits of this proposed rule are to reduce the number of accidents in all commercial diving operations that the Coast Guard has responsibility for (especially the offshore diving industry), as well as to minimize the adverse impacts in the event that an accident occurs.
Based on a review of current Association of Diving Contractors International industry information and Bureau of Labor Statistics diving population data, there are almost 200 domestic firms involved in commercial diving operations, of which 87 are subject to Coast Guard jurisdiction. Approximately 75 of these firms are registered with ADCI and, as such, are required to comply with the ADCI consensus standards. We estimate there are 12 firms covered by Coast Guard jurisdiction that are not members of ADCI. Table 4 demonstrates generally how Coast Guard went from the commercial diving population to a distribution of dive types and firms both within the ADCI framework and without.
Table 4—USCG Regulated Commercial Diving by Type and Firm Composition
|Item||Population of USCG regulated commercial divers by type||Total|
|Saturation *||SCUBA **||Surface supplied air ***||Mixed gas|
|100 fsw/no decompression||Other|
|ADCI Dive teams||24||10||23||38||19||114|
|Non-ADCI Dive Teams||0||0||5||7||0||12|
|ADCI Marine Firms ****||12||10||13||21||19||75|
|Non-ADCI Marine Firms *****||0||0||5||7||0||12|
|Start Printed Page 9161|
|* Number of Saturation Vessels * 14 crewman * 2 crews.|
|** USCG estimate of 5% of total diver population.|
|*** USCG estimates based upon ADCI member distribution.|
|**** Known number of ADCI firms.|
|***** Inferred Number of Firms based upon “excess” (not accounted for in ADCI) Diver population.|
The key population subset affected by the manning additional costs is the Surface Supplied Air 100fsw/no decompression mode. As shown in Table 5, both ADCI and no-ADCI firm groups are affected given the CG decision to increase the number of dive team members by one number. Most of the remaining costs impact the non-ADCI members, since we cannot confirm they are following ADCI protocols. Also, one qualification for saturation diving, that of taking a medical course every two years for saturation diving technicians, is an additional requirement for ADCI divers in that mode. Since we assume that non-ADCI commercial diving is composed of small firms and simpler diving modes than the complex saturation diving mode, this requirement does not affect them.
In addition, total TPO (auditor) population is expected to be 12. The TPO population includes current 10 auditors and the two estimated to be required by the non-ADCI firms.
We considered four alternatives before settling on the approach proposed in this notice of proposed rulemaking (NPRM).
1. Take no action. We would leave the existing regulations in place without updating them. Voluntary compliance with commercial diving industry consensus standards and the possibility of civil liability would continue to be the primary drivers of improvements in commercial diver safety. We think this is inconsistent with our regulatory Start Printed Page 9162responsibility to promote safety, and it also ignores the fact that some members of industry and the general public have criticized our existing regulations for being out of date.
2. Develop an international code. We would work with the International Maritime Organization to update its Code of Safety for Diving Systems, and adopt it as being applicable to all U.S. commercial diving operations wherever they were occurring. This could promote diver safety, and we do not rule out continued involvement in assisting in development of the standard. However, it would take years to develop and would not be effective without additional requirements necessary to further define the vague language that often accompanies international codes. Furthermore, we believe the existing IMO Code, coupled with the U.S. regulations we propose in this NPRM, should be applicable for U.S. vessels on an international voyage, but do not believe the international requirements should necessarily be imposed on U.S. vessels that are not engaged on international voyages.
3. Development of unique Coast Guard regulations: Under this alternative, the Coast Guard would develop its own updated regulations without reference to existing industry standards. This would involve additional regulatory time and effort for the Coast Guard, and ultimately might produce regulations that are similar to existing industry standards. However, this alternative would be contrary to the National Technology Transfer and Advancement Act, 15 U.S.C. 272 note, which requires agencies to use voluntary private sector consensus standards in their regulatory activities unless the agency provides Congress, through OMB, with an explanation of why using these standards would be inconsistent with applicable law or otherwise impractical. Additionally, Coast Guard developed standards would likely place diving firms who are members of ADCI in the position of facing duplicative enforcement costs, due to the fact that they are already complying with the ADCI guidelines.
4. Adopting Industry Standards without Manning Changes Alternative: We considered and rejected this alternative, which entails proposing regulations that incorporate accepted industry consensus standards (e.g. ADCI International Consensus Standards for Commercial Diving and Underwater Operations, 6th edition), but without an increase in manning that CG might want. This would codify many current consensus industry standards and provide enforcement capability. CG would incorporate all or most of what is in the ADCI consensus standards. However, CG could not incorporate it in total because some of the items in our existing regulations are not included in the ADCI standard. Much of what is written in the proposed regulations is written to augment the consensus standards to ensure previous requirements are not lost. CG ultimately rejected this approach, although less expensive, because of the lack of direct manning benefits in reducing fatalities and injuries.
5. Accepted alternative: Adaptation of industry standards: We considered and accepted this alternative, which entails proposing regulations that incorporate accepted industry consensus standards (e.g. ADCI International Consensus Standards for Commercial Diving and Underwater Operations, 6th edition). This will codify many current consensus industry standards and provide enforcement capability. CG incorporated most of what is in the ADCI consensus standards. CG could not incorporate it in total because some of the items in our existing regulations are not included in the ADCI standard. Much of what is written in the proposed regulations is written to augment the consensus standards to ensure previous requirements are not lost. CG used our existing regulations as a baseline and incorporated ADCI mostly based on that and the recommendations we got from industry on certain topics. These requirements also include an increase in manning (by one person) for the Surface Supplied Air no decompression mode.
Table 6 summarizes these alternatives.
Table 6—Description of Alternatives
|Take No Action||None||None||Not preferred because of risks that appear to still exist within the industry in spite of ADCI protocols.|
|Develop an International Code||Likely Costlier and less Timely than best approach due to Increased No of Parties Involved||Reduce Remaining Risk||Not preferred because of timely expense of having many parties involved that would have slowed progress in getting a rule out expeditiously.|
|Develop Unique Coast Guard Regulations||Might be Costlier due to Duplication with ADCI rules||Reduce Remaining Risk||Not preferred because of high risk of duplication of many of ADCI protocols that already exist.|
|Proposed ADCI Duplicative Rule in NPRM without Manning||$400,000||Reduce Remaining Risk||Marginal Approach especially given ADCI standards that still would not cover all CG desired requirements.|
|Proposed Rule in NPRM with Manning||$1.81 million||$2.4 million||Best Approach consistent with comprehensive, extensive and timely approach that gives the best bang for the buck.|
This proposed rule calls for CDOs and commercial divers to comply with a new regulatory baseline that is based on the industry-developed consensus standards of ADCI plus certain CG additions (in manning and medical area). We believe the majority (75 out of 87 identified commercial diving firms) of the affected population is in compliance with the proposed baseline. We know that the 75 ADCI firms are in general (except for manning and medical upgrades from CG) in compliance or else they would not qualify for ADCI membership. Members of ADCI must meet the Association's standard or face a suspension of their membership and potential loss of contracts. For example, ADCI members who fail an ADCI audit inspired by a complaint or a random audit exercise, are given time to correct the deficiency. If the deficiency is not corrected in a reasonable time, ADCI will (and has in the past) dis-enroll the offending member. Members generally know this Start Printed Page 9163is a dangerous route to take as the re-enrollment process is very expensive, requiring complete audits of every facet of their operation. In general, not having the ADCI certification will likely result in fewer work opportunities particularly with the oil and natural gas industries.
We have no gauge of any compliance for the inferred non-ADCI firms. However, we anticipate that some CDOs and divers will need to take steps to ensure compliance with the proposed audit system, drills and exercises, medical examination requirements, personal operational requirements, and reporting/recordkeeping requirements. We assess the costs for these CDOs and divers not already in compliance with ADCI (based upon the twelve Non-ADCI firms), as well as for all CDOs and divers to meet the other requirements added by the Coast Guard.
The costs impacting this rule are from changes in requirements in Dive manning, Drills, Audits, Med Issues, Records and Documentation. Total dive manning industry requirements are based upon 28 (23 ADCI and 5 non-ADCI) incremental divers in that SSA mode. Audits are required both internally and by external means (TPO) and range from $176-$2,096 depending on the cycle or vessel/firm. Drills can cost from $3300-$14000 per drill/firm depending on type (Standard Operations Review, Diver Recovery, or Emergency Rescue) for an annual total cost of $18000-26000. Medical costs comprise two items: The first item is an annual medical exam for the 55 non-ADCI divers while the second is a biennial training session on cardiopulmonary resuscitation (CPR) and first aid for Saturation Technicians that were not ADCI required (an oversight expected to be corrected in the near future) training. The costs of the first medical item are the 55 non-ADCI divers times the annual medical examination costs plus the records storage costs for a total $23,375 or ($1948 per firm). The second cost is the $60 cost of the training every other year times the Saturation Technicians (96) for a total of $5,760.
Costs for CDOs are shown in Table 7.
Table 7—Average Cost per Firm: Commercial Diving NPRM
|Rule requirements||Cost per CDO (2012 $)|
|Recordkeeping & Documentation||2,331|
|Medical I: Exams||1,948|
|Medical II: Training||240|

The majority of the costs are the result of new dive manning requirements, particularly for surface-supplied air. The proposed costs are the minimum required as, for example, adding more than one diver for all of the other modes would not be cost effective and in some cases. likely counter-productive. The dive manning levels now comport with industry practices.
Requirements for dive manning were calculated by first identifying the marine commercial diving population (BLS, ADCI sources) and developing the mode (Saturation, SCUBA, 3 types of Surface Supplied Air, and Mixed Gas) teams as explained in the population development description. CG subject matter experts considered the ADCI requirements and then decided another team member (Dive Tender) was necessary for Surface Supplied Air (100fsw/No decompression mode) (SSAn). The decision was based upon the notion that all divers in the water had to have a dive tender taking care of all the umbilical related lines for the in-the-water diver. That increment was then multiplied times the number of SSA teams found earlier. The per man cost was from BLS 2012 Commercial Diving Apprentice level and loaded with a 1.42 factor again based upon BLS information. All labor costs are generally based upon either an apprentice or a median experienced diver (loaded wages of $52,000-69,000).
For TPOs, the total costs estimated are $14.9 thousands of dollars over ten years due to the NPRM. The majority of costs accrue to labor requirements for various activities (developing the TPO auditor application, change of TPO auditor, and storage of audit records).
We estimate the total 10-year cost of the proposed rule to the commercial diving industry and third party organizations to be $17.8 million undiscounted, or $12.5 million at a 7-percent discount rate. We estimate the annualized cost of the proposed rule to be $1.78 million at a 7-percent discount rate. In addition to the private sector costs, we estimate the government will incur ($27,874) in annual reporting and record keeping review costs. This increases the total 10-year cost of the proposed rule to $18.1 million ($1.81 million annualized, 7-percent discount rate) (Table 8).

The primary benefits of this proposed rule are based on the reduction in risk of fatalities as well as injuries related to commercial diving incidents and are estimated from casualties foregone or mitigated as shown in Table 9.
Table 9—Rule Requirements and Associated Benefits
|Dive Manning||Requires non-decompression Surface Supplied Air dive teams to add a 5th member to handle lines as a novice member.|
|Drills||Requires CDO operators to conduct a series of drills at least monthly to maintain skill levels in emergencies.|
|Audits||Requires all CDOs and associated vessels to have timely audits to record existing conditions of all equipment and record procedures. Consistent with ADCI requirements.|
|Start Printed Page 9165|
|Recordkeeping & Documentation||Requires CDO s to develop and maintain for 5 years records of various aspects of CD operations from equipment maintenance to diving activities, to CG notifications, to logbooks. Maintaining records also assists the CDO by reminding him or her that actions are needed to remain in compliance with the rules.|
|Medical I: Exams||Requires all CDs, especially non-ADCI CDs to obtain an annual medical exam complete with hyperbaric analysis emulating the current ADCI requirements.|
|Medical II: Training||Requires certain members of a Saturation Dive Team (life support technician and saturation technician) to have a CPR & first aid certification.|
We reviewed the Marine Information for Safety and Law Enforcement (MISLE) data set of the commercial diving fatalities from 2002-2011 (12 fatalities- an average 1.2 per year and 8 injuries an average of .8 per year). Exhibit 1 shows the distribution of fatalities and injuries over the ten year period.
The incident reports suggest deficiencies in commercial diving operations, which would be addressed by the proposed provision, For dive manning, we identified 4 incidents that could benefit from the NPRM. Specific issues identified include lack of proper manning, lack of proper medical examination protocols, lack of maintenance of equipment, lack of drills lack of audits, etc. By identifying specific issues within each incident that likely would be mitigated by the NPRM, and applying an effectiveness factor, we were able to estimate a mitigated value using the value of a statistical life (VSL) approach.

Table 10—Incident Links to the Proposed Rule
|Activity ID||Related provision||Justification|
|1483715||Personnel Operational Requirements||Report indicated a standby diver was not properly suited up and ready to deploy as required by proposed rule. Investigative officer as well as fellow divers (during interviews) identified this as a potential cause.|
| ||Drills||Additional drills could have exposed diver to a hot suit, reminded to follow procedures when in trouble, and provided practice on removing equipment.|
| ||Audits||Regular audit procedures would likely have uncovered issues with equipment maintenance as well as operational procedures and readiness.|
|Start Printed Page 9166|
|1645241||Records & Documentation Related to Equipment Inspection||Problems were discovered with the helmet. However, diver-owned/-maintained helmet lacked a comprehensive record of repairs and maintenance. No records available to indicate when breathing hoses used by diver were last pressure tested or hydrostatic tested. Proposed regulation requires that log books be updated to track equipment tests. This could have ensured equipment was inspected periodically or a pre-dive inspection of equipment was conducted.|
| ||Audits||Auditing requirement may have identified the marginal state of maintenance of the diver's helmet. Furthermore, audit would have likely discovered that the vessel did not have a supply of medical-use oxygen on board.|
| ||Personnel Operational Requirements||Standby diver was not outfitted with any rescue related equipment to address the situation as required by proposed rule.|
| ||Drills||Drills required by proposed rule would help ensure diver follows procedure in an emergency. Diver did not slide the pneumofathometer underneath his neoprene neck dam and into his helmet. This would have taken him several seconds to do, but it could have provided him with an alternate source of breathing air.|
|2270536||Personnel Operational Requirements||Report indicated that company personnel displayed fatigue due to lack of sleep. Proposed rule would include 12 hour work hour limits in 24 hour period.|
| ||Drills||Drills would have improved the probability divers followed written and established safety procedure. As indicated in interviews, “there was no safety meeting for the dive crew prior to incident. Divers were unaware of any safety procedure or plan to follow in case an emergency to retrieve an injured diver out of the water.” As stated under the observations by the inspecting officer, “Training for dive team personnel seemed to be lacking.”|
| ||Records and Documentation Related to Equipment Inspection||Interviews indicated that the diver's umbilical may have been fouled. Documentation of maintenance and inspection of equipment is required under the proposed regulation. This could have helped ensure equipment was periodically inspected.|
|2734747||Medical Exams||Proper medical examination may have revealed tears or irregularities in the diver's lungs and kept him from diving.|
| ||Audits||Audits would ensure compliance with the medical fitness requirement for divers.|
| ||Records and Documentation Related to Medical Records||Documentation of medical examination is required by the proposed rule and maintains a history of medical conditions that could be used to avoid putting a diver in danger.|
|2765094||Personnel Operational Requirements||Standby diver was not ready to enter water as required by rule.|
| ||Audits||Regular Audits may identify failures of sufficient manning/certification levels of the dive team.|
| ||Drills||Rescue diver had trouble donning gear when preparing to enter water. Investigating officer recommendation is for monthly emergency rescue and recovery diving training for all commercial diving vessels. In addition to a fatality, multiple injuries resulted from incident.|
|3281272||Personnel Operational Requirements||One of the supervisors was also the standby diver. Proposed rules would not allow multiple responsibilities.|
| ||Audits||Regular Audits may identify failures of sufficient manning/certification levels of the dive team.|
| ||Medical Exam||Diver had previously unknown cardiac condition. A medical exam focused on hyperbaric exposure would have led to a cardiac exam which could have identified the cardiac condition and not permitted the dive.|
|3100303||Records and Documentation Related to Medical Records||Documentation of diver's medical fitness may identify the diver's condition and medication risk.|
|2866598||Drills||Delays were experience in recovering troubled diver. Drills would have identified the difficulty of one tender/diver conducting diver retrieval.|
| ||Personnel Operational Requirements||Superintendent also was serving as dive supervisor. The proposed rules would not allow multiple responsibilities.|
| ||Audits||Audits would ensure compliance with the medical fitness requirement for divers.|
| ||Records and Documentation||Documentation serving as a guide and checklist during the JHA may have prevented the diver's entanglement and the uncontrolled ascent of the lift bags.|
|1970383||Medical Exams||Lab test results indicated diver had hypertensive heart disease and drowned. Potential causal factor for this fatality was a pre-existing medical condition apparently aggravated by the individual performing strenuous activity while diving. Medical exams may have identified this precondition and prevented fatality.|
|2762375||Personnel Operation Requirements||The need for a diver to work for such extended periods indicates a lack of sufficient manning as required by rule.|
| ||Audits||Regular audits would identify substandard practices and excessive work hours resulting in fatigue.|
|1600506||Personnel Operational requirements||Dive supervisor was acting as the diving tender. The Diving Supervisor could not oversee the safety of the operation if he was performing dive tender duties. The proposed rules would not allow multiple responsibilities.|
|2765094||(See Details Above)||(See Details Above).|
For safety and security analysis, the VSL approach is used to monetize the value of fatalities prevented. The VSL does not represent the dollar value of a person's life, but the amount society would be willing to pay to reduce the probability of death. The VSL value used in this analysis to calculate an average annual cost of fatalities mitigated is $9.1 million.
The resulting benefit of the NPRM is $2.4 million. Subtracting out the $1.46 million in manning costs yields a marginal benefit of $940,000 for the manning provisions only. This amount is also the marginal fatality benefit for the rule since benefits from the other items could not be quantified even though they provide benefits. For example, the summaries of the following two case studies illustrate how complex and difficult it is to estimate benefits for this rule let alone quantify them.
Case Review Example 1
Incident Report 2765094
Vessel: Rowan Halifax/Global Explorer
Edited Brief from MISLE (see RA for complete text)
Commercial divers using surface-supplied air were working on the rigging of the legs of a sunken MODU. A diver was attempting to attach a 2 and 3/4 inch chain to a shackle for pre-rigging the MODU. Shortly after diver 1entered the water, there was a loss of communication with him, although a gurgling sound inside helmet was heard. The standby diver was ordered to splash. Diver 1 visibly panics and begins ascent towards diving bell Diver 2 dons gear, but has trouble with airflow to helmet. Problem fixed and he enters the water. Somehow Diver 1's helmet lands in worksite. Diver 2 descends, switching to 14% O2. He pulled his way to Diver 1 via latter's hose. He notices Diver 1's helmet from 20 feet away. Diver 2 arrives at Diver 1, shakes him with no response. Diver 2 notifies topside to pull up slack. Divers arrive at bell and with standby diver, attempt to pull Diver 1 into bell. Diver 1 is finally pulled up topside. Diver 2 becomes fouled on the bell, then unfouls himself. He begins his ascent but switches to air “on the fly”. Vessel paramedic performs lifesaving procedures. Since the paramedic is not hyperbaric qualified, backup is ordered into hyperbaric chamber to continue lifesaving procedures. Shore side physician finally orders halt to lifesaving procedures. Shortly afterwards, Diver 2 shows signs of the bends, while backup, still “dirty”, from an earlier dive that day, experiences decompression sickness. Investigation concluded that there was inadequate supervision and a good rule was misused.
Location Lat 028°04″4′ N, Lon 092°42″0′ W Gulf of Mexico.
Supervisor did not have a standby diver ready on a moment's notice to splash and assist another diver in the water. The proposed NPRM rules provide for a very strict regime for the supervisor to follow. From Section 290 (a), (b) and (c) clearly require the supervisor to make sure “. . . that minimum dive team requirements are met . . .” and “ensure that the necessary levels of personnel and equipment are available for all commercial diving operations.” Further, Section 197.222 of the NPRM requires “Each supervisor . . . must . . .: (a) Comply with this subpart and The applicable requirements for dive supervisors and diving modes outlined in sections 3.0 and 4.0 of the ADCI Standards (incorporated by reference . . .) . . .
Fatality at least partially resulted from inadequate supervision according to the report's conclusions. From the facts of the report, the standby diver was not ready to splash at a moment's notice and subsequently had equipment issues. This delay contributed to valuable time in getting the troubled diver out of the water. Also, the vessel paramedic was not trained in hyperbaric ailments.
Regular Audits may identify failures of sufficient manning/certification levels of the dive team.
Regular drills may have mitigated this incident. The rescue diver had trouble donning gear when preparing to enter water. Investigating officer recommendation is for monthly emergency rescue and recovery diving training for all commercial diving vessels. In addition to a fatality, multiple injuries resulted from incident.

Edited Brief from MISLE (see RA for complete text)
On January 8, 2011, a series of divers were engaged in bottom cleaning, through solo dives, on the NS Power from a series of other vessels including the King Arthur. Four divers used in sequence to perform bottom cleaning work on the NS Power. During the course of the work evolution, a diver's helmet neck seal failed flooding the helmet. While the diver was able to leave the water, delay caused time constraints on the activity.. Then another diver reported regulator problems in his dive. Attempts to retrieve him are less than by the book and result in his drowning. Some 13 hours after the beginning of the dive evolution, Galveston receives word of an unresponsive diver on the King Arthur.
15 NM SE Galveston Texas Galveston Bay
From the MISLE report: dive support team members were negligent in their duties while a diver was in the water resulting in the loss of life. Investigation concluded that there was inadequate supervision and a good rule was misused as well as active failures of equipment. Supervisor did not have a standby diver ready on a moment's notice to splash and assist another diver in the water. The proposed NPRM rules provide for a very strict regime for the supervisor to follow. From Section 290 (a), (b) and (c) clearly require the supervisor to make sure “. . . that minimum dive team requirements are met . . .” and “ensure that the necessary levels of personnel and equipment are available for all commercial diving operations.” Further, Section 197.222 of the NPRM requires “Each supervisor . . . must . . .: (a) Comply with this subpart and The applicable requirements for dive supervisors and diving modes outlined in sections 3.0 and 4.0 of the ADCI Standards (incorporated by reference . . .) . . .
Regular Audits may identify failures of sufficient manning/certification levels of the dive team.
Regular drills may have mitigated this incident. The rescue diver had trouble donning gear when preparing to enter water.
In both cases, the addition of one more dive team member so that responsibilities were adequately spread around might have made all the difference in the world to the victims. In addition, other requirements of the NPRM rule could have mitigated the incidents. The rule's other benefits besides proper manning and manning procedures, while very visible, are more difficult to quantify. They are drills, audits, records and documentation, as well as medical requirements.
As seen in the first example case, regular drills likely would have mitigated one of the problems in that incident. Drills provide regular practice for situations that require immediate instinctive response.
Regular audits would have provided a paper trail to maintenance needs and if recommendations were followed through on. Audit procedures likely would have mitigated issues ion both incidents. Records and documentation are parallel with audits in providing a trail of responsibility for Start Printed Page 9168maintaining equipment in proper working order.
Finally, at least two incidents in our baseline and one in the cases above might have been mitigated if the divers were undergoing regular medical examinations. Also, one other medical requirement in the NPRM rule has certain saturation dive team members taking CPR and first aid training. This requirement, only for the saturation dive team technicians (all other dive team members already satisfy this requirement), is critical to the successful operation of that dive mode.
Injury mitigation also is a benefit of this rule. Almost $117,000 per year in injury mitigation benefits are received from this rule as well. These benefits result from improved protocols in a wide variety of areas covered by the rule.
The total net benefits from the rule are $1,056,000 combined fatality mitigation and injury mitigation.
We also used a breakeven analysis approach for benefit estimation for the other rule items. In general, the typical CDO incident involves the death or injury of 1 diver, therefore the breakeven comparison against the VSL for 1 fatality is applicable, rather than other breakeven scenarios.
Table 11—Incremental Breakeven Analysis of Proposed Rule
|Item||Benefits description||Average annual cost *||Net benefits (7%, $ millions)||Fatalities reduced to breakeven|
| ||Annualized (7%, millions)|
|Proposed Rule Increment:|
|Manning||Increase 1 crewman/team for SSA for both ADCI and non-ADCI firms||2.4||1.46||0.94||N/A.|
|Documentation & Recordkeeping||Assists CG with enforcement||Not Quantifiable||0.205||N/A||1 every 44 years.|
|Drills||Non-ADCI Firm Drills provides regular training||Not Quantifiable||0.0437||N/A||1 every 208 years.|
|Audits||Non-ADCI Firm Audits assists CG with enforcement||Not Quantifiable||.0426||N/A||1 every 214 years.|
|Medical Exams||Medical Exams for Non-ADCI Firms provides safety measure||Not Quantifiable||0.0238||N/A||1 every 389 years.|
|Medical Training||Support Saturation Diver Crewmen receive First Aid and CPR Training||Not Quantifiable||0.003||N/A||1 every 3,056 years.|

|* Total may not sum due to rounding.|
We assume that this proposed rule would result in a constant reduction in the risk of fatality due to a commercial diving fatal accident every year following the rule's implementation and therefore use annualized costs in the equation. For these other rule items, we use annualized costs at a 7-percent discount rate over a 10-year period, or $.3 million, for this proposed rule. We then take the $9.1 million,
as the benefit that would be derived from the proposed rule if one fatality per year is prevented and compare it to the annualized individual item's cost that would be incurred (e.g. for drills: $9.1 million/$43,729=218 years). At a 7-percent discount rate, this proposed rule's other cost elements would need to prevent anywhere from 1 fatality in 44 years to 1 in 3,056 years to breakeven.
B. Small Entities
Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have conducted an Initial Regulatory Flexibility Analysis and considered whether this proposed rule would have a significant economic impact on a substantial number of small entities. The analysis is as follows: The U.S. Coast Guard (USCG) has performed this analysis of the impacts on small businesses from the proposed rule. USCG performed this assessment using the cost information discussed in cost chapter of this RA.
Whenever an agency is required by section 553 of the Regulatory Flexibility Act of 1980 
(RFA) or any other law, to publish general notice of proposed rulemaking for any proposed rule, or publishes a notice of proposed rulemaking for an interpretative rule involving the internal revenue laws of the United States, the Regulatory Flexibility Act requires that the agency prepare and make available for public comment an initial regulatory flexibility analysis. The RFA requires that such analysis describe the impact of the proposed rule on small entities and that the initial regulatory flexibility analysis or a summary be published in the Federal Register at the time of the publication of general notice of proposed rulemaking for the rule.
In addition, the RFA requires that the agency transmit a copy of an initial regulatory flexibility analysis to the Chief Counsel for Advocacy of the Small Business Administration. In the case of an interpretative rule involving the internal revenue laws of the United States, The RFA's requirements apply to interpretative rules published in the Federal Register for codification in the Code of Federal Regulations, but only to the extent that such interpretative rules impose on small entities a collection of information requirement.
Under the Regulatory Flexibility Act 
the Coast Guard must consider whether the rule would have a significant economic impact on a substantial number of small entities. Small entities 
include small Start Printed Page 9169businesses,
small not-for-profit organizations that are independently owned and operated and are not dominant in their fields,
and small governmental jurisdictions with populations of less than 50,000.
Based on the information from this analysis, we found that:
- There are no governments or not-for-profit organizations which are anticipated to be affected by the proposed rule.
- There are 87 U.S. entities (all private firms) that would potentially be impacted by the proposed rule. Of the 87, 75 are ADCI-registered firms of which we have some information on, and 12 are non-ADCI firms of which we have no information on but are assumed to be small. Furthermore, of the 75 firms we can identify, we found ownership and revenue data for only 45 firms. Of these 45 firms, 37 were determined to be small entities based on available data.
- We assume firms without available ownership or revenue data are small. Therefore, of the 87 firms considered only 8 can be considered non-small given the evidence available for this analysis.
- Initial and annual recurring costs of the proposed rule would result in less than 1 percent impact on revenue for 32 percent of the small entities with available data;
- 68 percent of small entities with available data will incur costs greater than 1 percent of revenue.
This chapter provides an Initial Regulatory Flexibility Analysis for commercial diving operations.
Preliminary Initial Regulatory Flexibility Analysis
The Regulatory Flexibility Act of 1980 (Pub. L. 96-354) establishes “as a principle of regulatory issuance that agencies shall endeavor, consistent with the rule and of applicable statutes, to fit regulatory and informational requirements to the scale of the businesses, organizations, and governmental jurisdictions subject to regulation. To achieve this principle, agencies are required to solicit and consider flexible regulatory proposals and to explain the rationale for their actions to assure that such proposals are given serious consideration.”
Under the RFA, we are required to consider if this rule will have a significant economic impact on a substantial number of small entities. Agencies must perform a review to determine whether a rule will have such an impact. If the agency determines that it will, the agency must prepare a regulatory flexibility analysis as described in the RFA. Under Section 603(b) of the RFA, the Initial Regulatory Flexibility Analysis (IRFA) must provide and address:
- A description of the reasons why action by the agency is being considered;
- A succinct statement of the objectives of, and legal basis for, the proposed rule;
- A description of and, where feasible, an estimate of the number of small entities to which the proposed rule will apply;
- A description of the projected reporting, recordkeeping and other compliance requirements of the proposed rule, including an estimate of the classes of small entities which will be subject to the requirement and the type of professional skills necessary for preparation of the report or record;
- An identification, to the extent practicable, of all relevant Federal rules which may duplicate, overlap or conflict with the proposed rule;
- A description of any significant alternatives to the proposed rule which accomplish the stated objectives of the applicable statutes and which minimize any significant economic impact of the proposed rule on 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 rule affects only small private entities. The following describes the Initial Regulatory Flexibility Act (TRFA) process for this rule.
We determined that the rule affects a variety of small private entities and therefore, based on the requirements mentioned above, we have prepared the following IRFA assessing the impact on small entities for this proposed rule. The analysis presented below addresses the issues specific to small entities that we have not addressed elsewhere in this RA
5.2 IRFA Requirements
5.2.1 Descriptions of Reasons Why Action of by the Agency Is Being Considered
Agencies take regulatory action for various reasons, one being the failure of the market to reach the socially optimal outcome. This can occur when there are economic incentives lacking for industry to pursue that outcome and such market failures are the impetus for this proposed rule. A negative externality is the byproduct of a transaction between two parties that is not accounted for in the transaction. Vessels and commercial diving operations that operate with lower safety standards may cause harm or increased risk of harm without accounting for the consequences to third parties, who do not directly participate in the business transactions of the affected entities. These costs are not borne by the responsible entities and are therefore external to the business decisions of the responsible entity. Section 4.2 describes the externality addressed by this rule.
Objectives of, and Legal Basis for, the Proposed Rule
The purpose of this rulemaking is to clarify and update our existing commercial diving regulations to reflect current industry best practices and to facilitate the use of approved third-party organizations (TPOs) in ensuring regulatory compliance. There has been no update since the 1978 original diving rules.
In addition, a series of reports on commercial diving safety demonstrated a need for updating USCG commercial diving regulations. These reports were developed in response to a series of commercial diving accidents that gained major public attention starting with one in 1996. The report titled “Investigation into the Circumstances Surrounding the Commercial Diving Accident Onboard the Mobile Offshore Diving Unit Cliff's Drilling Rig No. 12 on March 4, 1996 with the Loss of Life” influenced the Coast Guard to improve its regulations for commercial diving. That report, released in March, 2001, and also known as the RIG 12 Report, started a Start Printed Page 9170process that has slowly gained momentum these past few years. The most recent findings, the 2008 National Offshore Safety Advisory Committee (NOSAC) report, provided Coast Guard with additional appropriate information regarding the industry and its safety efforts. The objective of the proposed rule is to establish safety regulations governing the inspection, standards, and operation of commercial diving operations. The proposed rule would promote safer work practices and reduce casualties in commercial diving operations by ensuring that those operations adhere to recommended safety standards and operational protocols.
The statutory bases for the Coast Guard's rulemaking are located in: 33 U.S.C. 1509(b), which requires safety regulations for deepwater ports; 43 U.S.C. 1333(d)(1), which permits safety regulations for Outer Continental Shelf (OCS) facilities and their equipment; 46 U.S.C. 3306, which requires regulations to implement subtitle II of Title 46 of the U.S. Code with respect to inspected vessels, including offshore supply vessels (OSVs) and their equipment; 46 U.S.C. 3703, which requires safety and environmental protection regulations for liquid bulk dangerous cargo carriers and their equipment, to be issued after consultation with Federal, State, and local governments and with private sector entities; and 46 U.S.C. 6101, which requires regulations for reporting and investigating marine casualties. These statutes confer regulatory authority on the Secretary of Homeland Security, who has delegated this authority to the Coast Guard; DHS Delegation No. 0170.1(75), (90), and (92). In addition, we are conducting this rulemaking in accordance with a December 19, 1979, Memorandum of Understanding between the Coast Guard and the Occupational Safety and Health Administration (OSHA), which regulates commercial diving operations conducted near shore or in U.S. internal waters.
Description and Estimate of the Number of Small Entities to Which the Proposed Rule Will Apply
126.96.36.199 Data Development
We used MISLE owner and operator name and address information as well as ADCI member information to research public databases (MANTA) for entity type (subsidiary or parent company), primary line of business, employee size, revenue, and other information.
We matched this information to the Small Business Administration's “Table of Small Business Size Standards” to determine if an entity is small in its primary line of business as classified in the North American Industry Classification System (NAICS).
ADCI member data and Coast Guard data shows that there are 87 entities engaging in marine oriented commercial diving in the 2009-2011 timeframe. We acknowledge that only 75 diving firms belong to the ADCI.
USCG estimates that number of non-ADCI firms to be 12 based on our total population estimate (see affected population section for details). We found revenue and employment data for 45 firms that were ADCI in origin. Of the 45 firms, 37 were determined to be small businesses according to Small Business Administration standards. We assume that entities without small business data are small. In Table 12, we provide a summary of the small business data. As a result of our analysis, we concluded that small entities make up approximately 79 percent of the total affected marine population ((37 known small firms + 10 estimated and likely small firms + 30 firms with no revenue data)/87 total marine firms).

Industries Affected by the Proposed Rule
A brief description of the industries 
most affected by this proposed rule is presented as follows:
236220 Commercial and Institutional Building Construction—This industry comprises establishments primarily responsible for the construction (including new work, additions, alterations, maintenance, and repairs) of commercial and institutional buildings and related structures, such as stadiums, grain elevators, and indoor swimming facilities. This industry includes establishments responsible for the on-site assembly of modular or prefabricated commercial and institutional buildings. Included in this Start Printed Page 9171industry are commercial and institutional building general contractors, commercial and institutional building for-sale builders, commercial and institutional building design-build firms, and commercial and institutional building project construction management firms.
237990 Other Heavy and Civil Engineering Construction—This industry comprises establishments primarily engaged in heavy and engineering construction projects (excluding highway, street, bridge, and distribution line construction). The work performed may include new work, reconstruction, rehabilitation, and repairs. Specialty trade contractors are included in this group if they are engaged in activities primarily related to engineering construction projects (excluding highway, street, bridge, distribution line, oil and gas structure, and utilities building and structure construction).

Revenue Impact on Small Entities
The regulatory costs in this rule (including Manning, Drills, Audits, Records & Documentation and Medical Examinations) are evaluated in total in the following conventional IRFA analysis. To estimate the revenue impact on the identified small businesses, we followed guidance from the U.S. Small Business Administration's Office of Advocacy's “A Guide for Government Agencies: How to Comply with the Regulatory Flexibility Act.” We compared the total cost per business to the revenue data collected to assess the impact of the rule to those businesses. Using this information we were able to estimate the impact as a percentage of revenue for the affected firms.
As a result of our analysis, we concluded that small entities with a significant impact likely comprise 68 percent of the small entity population evaluated. Of the 37 small entities with available business data, we determined that 32 percent of small entities would have an annual cost-to-revenue impact of less than 1 percent. Further, we estimated that 41 percent of the small entities would have a cost-to-revenue impact between 1 and 3 percent and 27 percent would have an impact equal to or greater than 3 percent. These results are summarized in Table 15. We estimate 68 percent of small entities would have an impact greater than 1 percent from a cost to revenue ratio perspective.Start Printed Page 9172

Description of the Projected Reporting, Recordkeeping, and Other Compliance Requirements of Small Entities
The Coast Guard expects new reporting or record keeping requirements resulting from this rule. The proposed rule impacts commercial marine diving operations under Coast Guard jurisdiction and requires each operation perform documentation preparation and maintenance tasks that fall under the category of reporting and recordkeeping. This documentation provides a historical record of when a piece of equipment was inspected or serviced and by whom. The process will also include the documentation of new equipment as often as new equipment is added to a firm's asset base. In addition, the documentation also takes into account logbook entries of diving activities as well as maintenance of logbooks, audit reporting, and operations manuals.
Duplication With Other Federal Rules
There are no relevant Federal rules that may duplicate, overlap, or conflict with the proposed rule. OSHA has commercial diving responsibility to the 3-mile limit, and Coast Guard has responsibility beyond the 3-mile limit, and also for any activity off of a Coast Guard inspected vessel within the 3-mile limit. The latter is composed of most of the non-Gulf of Mexico commercial divers discussed earlier.
Description of Any Significant Alternatives to the Proposed Rule
The Coast Guard considered four alternatives to the NPRM alternative. A description of these alternatives is presented in Chapter 1. In general, safety rules do not lend themselves to alternatives favoring smaller entities. Being a small entity does not change necessarily the safety requirement.
Three alternatives involved a different regulatory approach from a status quo and ranged from involving the IMO in a global rulemaking to a consolidation of OSHA and US Coast Guard rules. All were rejected for reasons presented in Chapter 1.
In accordance with the Regulatory Flexibility Act (5 U.S.C. 601-612) and section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), the Coast Guard considered whether this rulemaking would have a significant economic impact on a substantial number of small entities. The term “small entities” comprises small business, not-for-profit organizations and governmental jurisdictions with populations of less than 50,000. In reviewing the potential costs of compliance and the relative impact on a small business' revenue, the Coast Guard cannot certify the proposed rulemaking would not have a significant economic impact on a substantial number of small entities.
The Coast Guard will help small entities understand the proposed rulemaking so that they can better evaluate its effect on them and participate in the rulemaking process. The preamble of the proposed rulemaking provides small businesses or organizations an opportunity to comment and lists a point of contact for any questions concerning the proposed rulemaking's provisions or options for compliance.
Section 1 of Executive Order 13272 directs Federal agencies to establish procedures and policies to promote compliance with the Regulatory Flexibility Act. It also requires Federal agencies to review thoroughly draft rules to assess and take appropriate account of the potential impact on small businesses, small governmental jurisdictions, and small organizations, as provided by the Act.
Executive Order 13272 requires Federal agencies to notify the Chief Counsel for Advocacy of the Small Business Administration of any proposed rulemakings that may have a significant economic impact on a substantial number of small entities. The proposed rulemaking is anticipated to have a significant economic impact on a substantial number of small entities. USCG will seek input from the Chief Counsel for Advocacy of the Small Business Administration in the promulgation of this rulemaking.
The Coast Guard solicits comments from Advocacy on the proposed rulemaking and will give every appropriate consideration to any comments provided by Advocacy on the proposed rulemaking. Similarly, USCG has proffered a comment period to small entities in compliance with the Executive Order and relevant laws and regulations.
Small businesses are encouraged to contact the agency for more information on the proposed rulemaking. For questions on this proposed rulemaking, call Ken Smith at the US Coast Guard (202) 372-1413. The public may also write the Coast Guard at the following address: U.S. Coast Guard Headquarters, 2100 Second Street SW., Washington, DC 20593-0001.
C. Assistance for Small Entities
Under Section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), we want to assist small entities in understanding this proposed rule. If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and you have questions concerning its provisions or options for compliance, please consult Mr. Ken Smith, U.S Coast Guard, using the contact information listed above. 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 Coast Guard employees, call 1-888-REG-FAIR (1-888-734-3247). The Coast Guard will not retaliate against small entities that question or complain about this proposed rulemaking or any policy or action of the Coast Guard.
The Coast Guard Office of Domestic Compliance has prepared a notice to be Start Printed Page 9173circulated to the general public and to be placed on the Coast Guard's Web site to assist small businesses and other interested parties in understanding the proposed rulemaking. The Coast Guard plans to continue its coordination and communication with maritime organizations such as the Chamber of Shipping of America and other ship owner associations so that they may inform and assist their respective members with understanding the rule.
In compliance with Executive Order 13563,
USCG will offer a public comment period of at least 60 days. Information about the proposed rule will be provided to USCG contacts as well as through Federal Register notice and press releases to encourage public participation.
D. Collection of Information
This proposed rule would call for a new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). As defined in 5 CFR 1320.3(c), “collection of information” comprises reporting, recordkeeping, monitoring, posting, labeling, and other similar actions. The title and description of the new information collection, a description of those who must collect the information, and an estimate of the total annual burden follow. The estimate covers the time for reviewing instructions, searching existing sources of data, gathering and maintaining the data needed, and completing and reviewing the collection.
Title: Marine Occupational Health and Safety Standards for Commercial Diving Operations—46 CFR 197 Subpart B.
OMB Control Number: 1625-NEW.
Summary of the Collection of Information: This proposed rule would include reporting and record keeping requirements ranging from updating the operations manual, maintaining and periodically updating a log book, reporting and storing examination scores and certifications, and maintaining records of equipment inspections. The collection of information would aid the regulated public in assuring safe practices associated with commercial diving operations.
Need for Information: The Coast Guard needs this information to determine whether an entity meets the regulatory requirements.
Proposed Use of Information: The Coast Guard would use this information to determine compliance with the regulatory requirements.
Description of the Respondents: The respondents are owners and operators of U.S. commercial diving operations.
Number of Respondents: The burden of this proposed rule for this collection of information includes certifications, procurement of written materials, preparation of records, and records of inspections. This collection of information applies to owners/operators of commercial diving operations. We estimate the maximum number of respondents to be 87.
Frequency of Responses: This proposed rule would vary the number of responses each year by requirement. Details are provided in the preliminary regulatory analysis.
Burden of Response: The burden of response for each regulatory requirement varies. Details are provided in the preliminary regulatory analysis.
Estimate of Total Annual Burden: We estimate an annual burden of 6,059 hours for the industry.
As required by the Paperwork Reduction Act, we will submit a copy of this proposed rule to OMB for its review of the collection of information.
We ask for public comment on the proposed collection of information to help us determine how useful the information is; whether it can help us perform our functions better; whether it is readily available elsewhere; how accurate our estimate of the burden of collection is; how valid our methods for determining burden are; how we can improve the quality, usefulness, and clarity of the information; and how we can minimize the burden of collection.
If you submit comments on the collection of information, submit them both to OMB and to the Docket Management Facility where indicated under ADDRESSES, by the date under DATES.
You need not respond to a collection of information unless it displays a currently valid control number from OMB. Before the Coast Guard could enforce the collection of information requirements in this proposed rule, OMB would need to approve the Coast Guard's request to collect this information.
A rule has implications for federalism under Executive Order 13132, Federalism, if it has a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. We have analyzed this rule under that Order and have determined that it is consistent with the fundamental federalism principles and preemption requirements described in Executive Order 13132. Our analysis is explained below.
It is well settled that States may not regulate in categories reserved for regulation by the Coast Guard. It is also well settled, now, that all of the categories covered in 46 U.S.C. 3306, 3703, 7101, and 8101 (design, construction, alteration, repair, maintenance, operation, equipping, personnel qualification, and manning of vessels), as well as the reporting of casualties and any other category in which Congress intended the Coast Guard to be the sole source of a vessel's obligations, are within the field foreclosed from regulation by the States. (See the decision of the Supreme Court in the consolidated cases of United States v. Locke and Intertanko v. Locke, 529 U.S. 89, 120 S.Ct. 1135 (March 6, 2000)). This proposed rule regulates equipment and operations for commercial diving conducted from inspected vessels in order to promote the safety of life. States may not regulate within this category, and therefore, this rule is consistent with the principles of federalism and preemption requirements in Executive Order 13132. Additionally, Congress specifically granted the authority to regulate artificial islands, installations, and other devices permanently or temporarily attached to the OCS and in the waters adjacent thereto as it relates to the safety of life to the Secretary of the Department in which the Coast Guard is operating. This includes floating installations and other devices engaged in OCS activities. 43 U.S.C. 1333(d)(1) states that the Secretary “shall have authority to promulgate and enforce such reasonable regulations with respect to lights and other warning devices, safety equipment, and other matters relating to the promotion of safety of life and property on the artificial islands, installations, and other devices . . . as he may deem necessary.” As this proposed rule would regulate equipment and operations to ensure safety of life for commercial diving Start Printed Page 9174being conducted from such OCS installations, it falls within the scope of authority Congress granted exclusively to the Secretary. This authority has been delegated to the Coast Guard and is exercised in this proposed rule. Therefore, since the States may not regulate within this category, preemption under Executive Order 13132 is not an issue.
Finally, Congress granted the authority to regulate deepwater ports to the Secretary of Transportation. 33 U.S.C. 1509(b) states that the Secretary of Transportation “shall issue and enforce regulations with respect to lights and other warning devices, safety equipment, and other matters relating to the promotion of safety of life and property in any deepwater port and the waters adjacent thereto.” When the Coast Guard was an agency within the Department of Transportation, the authority to issue regulations with respect to safety on deepwater ports was delegated to the Coast Guard. See 49 CFR 1.46(s) (2002). The Homeland Security Act of 2002, Public Law 107-296, transferred the Coast Guard to the Department of Homeland Security. Pursuant to the Homeland Security Act, authorities that were delegated to the Coast Guard remained intact during this transfer by operation of law. The authority was then delegated to the Commandant of the Coast Guard through Department of Homeland Security Delegation 0170.1. Since this rule regulates equipment and operation to ensure safety for commercial diving being conducted from deepwater ports, it falls within the scope of authority that has been transferred and delegated to and exercised by the Coast Guard.
F. 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 (adjusted for inflation) or more in any one year. Though this proposed rule would not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble.
G. Taking of Private Property
This proposed rule would not cause a taking of private property or otherwise have taking implications under Executive Order 12630, Governmental Actions and Interference with Constitutionally Protected Property Rights.
H. Civil Justice Reform
This proposed 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.
I. Protection of Children
We have analyzed this proposed rule under Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks. This proposed rule is not an economically significant rule and would not create an environmental risk to health or risk to safety that might disproportionately affect children.
J. Indian Tribal Governments
This proposed rule does not have tribal implications under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, because it would 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.
K. Energy Effects
We have analyzed this proposed 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.
L. Technical Standards
The National Technology Transfer and Advancement Act (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. The proposed regulations use voluntary consensus standards developed by ADCI and would allow commercial diving operators to apply for equivalency determinations if they comply with similar voluntary consensus standards used by other organizations.
We have analyzed this proposed 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 made a preliminary determination that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment. A preliminary environmental analysis checklist supporting this determination is available in the docket where indicated under the “Public Participation and Request for Comments” section of this preamble. This rule is likely to be categorically excluded under section 2.B.2, figure 2-1, paragraphs (34)(a), (c), (d) and (e) of the Instruction and 6(a) of the Federal Register, Vol. 67, No. 141, Tuesday, July 23, 2002, page 48243. This proposed rule involves regulations that are procedural, involving reporting and recordkeeping requirements; regulations concerning the training and qualifying of maritime personnel; regulations concerning manning and equipping of vessels; regulations concerning equipment approval and carriage requirements; and regulatory actions involving vessel operation safety standards. We seek any comments or information that may lead to the discovery of a significant environmental impact from this proposed rule.

Commercial diving operations conducted in foreign waters.
A U.S. vessel that is conducting commercial diving operations in foreign waters, and a foreign vessel that is conducting commercial diving operations on the OCS of the U.S., must have diving systems that comply with the International Code of Safety for Diving Systems (incorporated by reference, see 46 CFR 197.202) and possess a valid international diving systems safety certificate issued by the vessel's flag administration or a party acting on that flag administration's behalf. U.S. vessels needing an international diving systems safety certificate must contact a recognized classification society authorized by the Coast Guard to issue international certificates in accordance with 46 CFR 8.320.
(a) For the purpose of enforcing this subpart, and to the extent needed to verify compliance with this subpart, the Officer in Charge, Marine Inspection (OCMI) may at any time inspect the records and observe the operations of any commercial diving operator (CDO) or third-party organization (TPO), and may interview any employee or person working on behalf of the CDO or TPO.
(b) For noncompliance with this subpart, the OCMI may suspend or revoke a U.S. vessel's certificate of inspection in accordance with 46 CFR part 2, or may suspend a U.S. vessel's international diving systems safety certificate.
(c) Vessels, OCS facilities, or deepwater ports that do not comply with these regulations are subject to the following enforcement actions:
(1) The District Commander or the Captain of the Port (COTP) may prohibit a noncompliant vessel from engaging in commercial diving operations. A noncompliant vessel conducting commercial diving operations on the navigable waters of the United States, as defined in 33 CFR 2.36, is subject to orders and penalties authorized by the Ports and Waterways Safety Act and its implementing regulations.
(2) The OCMI may prohibit a noncompliant vessel or OCS facility from engaging in commercial diving operations. A noncompliant OCS facility, or vessel engaged in an OCS activity, is subject to penalties and orders authorized by the Outer Continental Shelf Lands Act and its implementing regulations.
(3) The OCMI may prohibit a noncompliant deepwater port from engaging in commercial diving operations. A noncompliant deepwater port, or a vessel connected to a deepwater port, is subject to penalties and orders authorized by the Deepwater Port Act and its implementing regulations.
(a) As used in this section, an “audit” means a systematic, independent, and documented process for obtaining audit evidence, which can be evaluated objectively to determine the extent to which audit criteria are fulfilled. An audit may be limited to random selection of a representative sampling throughout the system that presents the auditor with sufficient objective evidence of system compliance. It includes a thorough review of appropriate reports, documents, records, and other objective evidence to verify compliance with applicable regulations. It may include, but is not limited to—
(1) Examining records;
(2) Asking responsible persons how they accomplish specific tasks;
(3) Observing persons performing required tasks;
(4) Examining equipment to insure proper maintenance and operation; and
(5) Checking training records and work environments.
(b) This section establishes procedures for third-party organizations (TPOs) to obtain the Commandant's approval to perform audits on behalf of the Coast Guard for the purpose of determining regulatory compliance of vessels, personnel, and equipment with Coast Guard regulations issued under this part, and establishes criteria for the performance of those audits.
(c) A TPO that the Commandant approves may—
(1) Conduct audits of logs, records, documents, equipment, drills, or other data to verify compliance with applicable Coast Guard regulations;
(2) Conduct audits of specific vessel operations and interview a TPO's personnel to verify compliance with applicable Coast Guard regulations; and
(3) Issue reports detailing the results of audits.
(d) To receive the Commandant's approval to perform audits in accordance with this section, a TPO must demonstrate the skills and experience necessary to assess compliance with the requirements of this part. It must demonstrate, without consideration for any recreational diving experience, that each of its auditors has—
(1) Successfully completed a commercial diving training course meeting the requirements of ANSI/ACDE-01-2009 (incorporated by reference, see 46 CFR 197.202);
(2) Served as a diving supervisor overseeing the specific diving mode to be audited, with an auditor of commercial SCUBA, surface-supplied air, or mixed-gas diving having overseen at least 500 commercial dives in that mode and an auditor of saturation diving having overseen at least 100 commercial dives in that mode;
(3) Successfully completed a lead auditor/assessor course that meets the requirements of International Organization for Standardization (ISO) 9001-2008 (incorporated by reference, see 46 CFR 197.202) or a Coast Guard-recognized equivalent; and
(4) Either conducted at least eight audits within the past 5 years of a commercial diving operation utilizing a recognized consensus standard, or Start Printed Page 9179successfully completed a required auditor apprenticeship consisting of at least four audits under the direction of a lead auditor.
(e) A TPO that the Commandant approves must notify the Commandant when it adds or removes an auditor. For each new auditor, the organization must demonstrate that the auditor qualifications specified in paragraph (c) of this section have been met.
