III. Background

    In a recent five year period, approximately 82.1 million people 
annually participated in recreational boating as an outdoor recreation 
activity in the United States.\1\ Of that population, approximately 
53.8 million people enjoyed recreational boating on a motorized 
recreational vessel. Unfortunately, motorized recreational boating 
poses risks, including property damage, human injury, and even death. 
One of these risks is boating casualties caused by persons being struck 
by a recreational vessel propeller. An additional, more recently 
discovered

[[Page 53366]]

risk is boating casualties caused by carbon monoxide (CO) poisoning. 
The Coast Guard is interested in measures to reduce these two specific 
risks, both of which involve persons near the rear of a motorized 
recreational vessel.

Series), available at http://warnell.forestry.uga.edu/nrrt/nsre/IRISRec/IRISRec12rpt.pdf. This number represents the estimated 
number of people, operators and passengers who participated in

---------------------------------------------------------------------------

    Under 46 U.S.C. chapter 43 (Recreational Vessels), the Secretary of 
the Department of Homeland Security is responsible for establishing 
minimum safety standards for recreational vessels and associated 
equipment, and for requiring installation, carrying, or use of 
associated equipment. See 46 U.S.C. 4302(a). The Coast Guard, on behalf 
of the Secretary, carries out this responsibility.

Propeller Strike-Related Casualties

    Since the mid-1990s, the Coast Guard has investigated the 
appropriate course of action to address propeller strike-related 
casualties, to understand the causes of these casualties, and to 
determine the best way to prevent casualties from occurring. The Coast 
Guard has solicited requests for comments on various proposals to 
reduce propeller strike-related casualties, and proposed and then 
withdrew two separate rulemakings addressing this issue. The first 
rulemaking sought public input on the use of swimming ladders, warning 
notices, clear aft vision, propeller-shaft engagement alarms, engine 
cut-off switches, and education to address recreational vessel and 
propeller strike-related casualties. See 60 FR 25191 (May 11, 1995) 
(Request for comments); 61 FR 13123 (Mar. 26, 1996) (Advance Notice of 
Proposed Rulemaking); 62 FR 22991 (Apr. 28, 1997) (Request for 
comments). The Coast Guard withdrew this rulemaking because of a lack 
of sufficient data for the proposals at that time. See 66 FR 63650 
(Dec. 10, 2001) (Notice of Withdrawal).
    At the same time the Coast Guard withdrew the first rulemaking, it 
initiated the second rulemaking, which focused on propeller injury 
mitigation devices commonly referred to as ``propeller guards.'' The 
notice of proposed rulemaking proposed requiring owners of certain 
recreational houseboats to either install a propeller guard or to use 
all of the following propeller injury avoidance measures: a swim ladder 
interlock, an aft visibility device, and an engine cut-off switch. See 
66 FR 63645 (Dec. 10, 2001). The Coast Guard withdrew this rulemaking 
after public comments raised several issues, including the lack of a 
practical definition of a houseboat and straightforward performance 
requirements, and the potential costs of installing propeller guards. 
See 72 FR 59064 (Oct. 18, 2007) (Notice of Withdrawal). In the Notice 
of Withdrawal, the Coast Guard stated that it is still ``exploring 
options that would more effectively prevent propeller injuries and 
impose a smaller burden on the economy,'' and specifically noted engine 
cut-off switches and boating safety education as two of those options. 
Id. at 59065.
    In 2006, the National Boating Safety Advisory Council (NBSAC) 
established a Propeller Injury Working Group to consider the 
development of educational formats, review of technologies, risk 
management techniques, accident scenarios, cost benefit analysis, and 
high-risk recreational vessel definitions and determinations. See NBSAC 
Resolution  2005-76-04, available at http://homeport.uscg.mil/NBSAC. The working group proposed four recommendations: (1) Develop a 
rental vessel education kit, (2) require the installation of engine 
cut-off switches, (3) require operators to use installed engine cut-off 
switches, and (4) require operators of vessels to shut off the engine 
when individuals in the water are within an unsafe distance from the 
vessel. NBSAC endorsed these recommendations and forwarded them to the 
Coast Guard for further consideration. See NBSAC Resolution 
 2006-77-01, 2006-77-02, 2006-77-03 and 2006-77-04, 
available at http://homeport.uscg.mil/NBSAC.
    To address NSBAC's second and third recommendations (NBSAC 
Resolution  2006-77-02 and 2006-77-03) involving the 
installation, maintenance, and use of engine cut-off switches \2\ and 
to follow-up on the discussion of engine cut-off switches in the Notice 
of Withdrawal of the propeller guard rulemaking, the Coast Guard 
initiated a separate rulemaking titled ``Installation and Use of Engine 
Cut-Off Switches'' (ECOS) (RIN 1625-AB34). In the ECOS rulemaking, the 
Coast Guard seeks to prevent recreational boating casualties caused by 
persons being struck by a recreational vessel or propeller when the 
vessel operator is separated from the operating controls (e.g., falls 
overboard or is ejected). The ECOS rulemaking, however, only addresses 
one cause of propeller-strikes. Recreational boaters in the water near 
the rear of a recreational vessel also face the possibility of being 
inadvertently struck by a vessel's propeller even when the vessel 
operator is in control of the vessel.
---------------------------------------------------------------------------

    \2\ In response to the first recommendation (NBSAC Resolution 
 2006-77-01), the Coast Guard developed a rental education 
kit, which is now available to vessel liveries through the following 
Web site: http://rentalboatsafety.com/participate.php.
---------------------------------------------------------------------------

    The Coast Guard is initiating this rulemaking to seek public input 
on NSBAC's fourth recommendation in NBSAC Resolution  2006-77-
04, as well as other options to prevent casualties caused when persons 
in the water near the rear of a recreational vessel are inadvertently 
struck by a vessel's propeller. For example, a person may be struck by 
a propeller when using the lower unit of the recreational vessel's 
propulsion system as a step to reboard the vessel. If the propeller is 
spinning while a person is attempting to use the lower unit as a step, 
the person may either step directly onto the spinning propeller or slip 
off the lower unit of the propulsion system and fall onto the spinning 
propeller resulting in severe injuries and possibly death.

CO Poisoning-Related Casualties

    Over the last decade, boating-related activities that require 
participants to be near the rear of a recreational vessel in close 
proximity to a vessel's engine exhaust emissions have increased in 
popularity. With an increase in the prevalence of these activities, 
casualties associated with these activities have also increased, and 
investigations of these casualties have led to an increased 
understanding of CO concentrations near the rear of recreational 
vessels.
    A potentially deadly gas that is odorless, colorless, and 
tasteless, CO occurs as a component of internal combustion engine 
exhaust. When inhaled, CO enters the bloodstream through the lungs and 
displaces the oxygen needed by the body, resulting in hypoxia 
(suffocation) of body tissues.
    In 2000, the National Park Service, in coordination with the 
National Institute for Occupational Safety and Health (NIOSH) and the 
Coast Guard, initiated a study to evaluate CO exposure from generators 
and propulsion engines on houseboats.\3\ This study revealed high 
concentrations of CO on and around houseboats using gasoline-powered 
generators. In 2002, the National Park Service, NIOSH, and the Coast 
Guard began working to measure CO levels on other types of recreational 
vessels and to evaluate new engineering technologies

[[Page 53367]]

designed to reduce CO poisonings related to the vessels' operation.

Control, National Institute for Occupational Safety and Health, 
NIOSH Health Hazard Evaluation Report: HETA #2000-0400-2956, HETA # 
2002-0325-2956, Glen Canyon National Recreation Area, Arizona and 
Utah (January 2005) available at http://www.cdc.gov/niosh/hhe/reports/pdfs/2000-0400-2956.pdf.
---------------------------------------------------------------------------

    In 2008, the Environmental Protection Agency (EPA) promulgated 
exhaust emission standards for marine engines, including first-time EPA 
standards for sterndrive and inboard engines. See 73 FR 59034 
(``Control of Emissions from Nonroad Spark-Ignition Engines and 
Equipment''). The EPA standards apply to new marine engines, and the 
Coast Guard expects these EPA standards to have a dramatic effect on 
the levels of CO in the exhaust emissions of new sterndrive and inboard 
engines and thus reduce CO levels on recreational vessels with such 
engines.
    In response to the EPA standards, as well as to address CO 
poisoning-related casualties, manufacturers have developed new 
catalyst-based low CO sterndrive and inboard engines. These EPA 
standards and resulting new technology, however, apply only to newly 
manufactured engines, and do not affect potentially dangerous levels of 
CO on recreational vessels with older engines.
    The National Association of State Boating Law Administrators 
(NASBLA), as well as some States, are also concerned with the issue of 
CO poisoning-related casualties, and efforts to address this issue 
cover both new as well as existing recreational engines by focusing on 
recreational vessel operation rather than on technology. NASBLA has 
been engaged in addressing this issue since 2003 and has developed a 
consensus model act prohibiting persons from operating any recreational 
vessel or having the engine idle while someone is in the water and 
holding onto the rear of the recreational vessel. See NASBLA Model Act 
for ``Safe Practices for Boat-Towed Watersports'' (September 10, 2007), 
available at http://nasbla.org/i4a/pages/index.cfm?pageid=3290. At 
least five States have enacted laws addressing CO poisoning-related 
casualties based on this model act.
     California and Washington have prohibited operating a 
recreational vessel or having the engine of the vessel idle while an 
individual is ``teak surfing, platform dragging, or bodysurfing 
behind'' \4\ or ``occupying or holding onto the swim platform, swim 
deck, swim step, or swim ladder of the vessel,'' except ``when an 
individual is occupying the swim platform, swim deck, swim step, or 
swim ladder for a very brief period of time while assisting with the 
docking or departure of the vessel, while exiting or entering the 
vessel, or while the vessel is engaged in law enforcement or emergency 
rescue activity.'' See Cal. Harb. & Nav. Code Sec.  681 (West); Wash. 
Rev. Code Ann. Sec.  79A.60.660 (West).
---------------------------------------------------------------------------

    \4\ ``Teak surfing'' or ``platform dragging'' means holding onto 
the swim platform, swim deck, swim step, swim ladder, or any portion 
of the exterior of the transom of a motor driven vessel for any 
amount of time while the motor driven vessel is underway at any 
speed. See Cal. Harb. & Nav. Code Sec.  681(d) (West); Wash. Rev. 
Code Ann. Sec.  79A.60.660(4) (West). ``Bodysurfing'' means swimming 
or floating on one's stomach or on one's back on or in the wake 
directly behind a motor driven vessel that is underway. See Cal. 
Harb. & Nav. Code Sec.  681(e) (West); Wash. Rev. Code Ann. Sec.  
79A.60.660(5) (West).
---------------------------------------------------------------------------

     Nevada has prohibited operation of a recreational vessel 
while any person is hanging onto, or sitting, standing or riding on, a 
swim platform or a swim ladder that is attached to the vessel as a form 
of reckless or negligent operation of a vessel. See Nev. Rev. Stat. 
Sec.  488.400; Nev. Admin. Code Sec.  488.435.
     Oregon prohibits operating a recreational vessel or having 
the vessel's engine idle while any person holds onto or occupies any 
portion of the vessel located aft of the transom, including a step, 
ladder, platform or deck, in order to ride on that portion of the 
vessel while the vessel is under way at any speed or to be pulled by 
the vessel, except when assisting in the docking or departure of the 
vessel, exiting or entering the vessel, or engaging in law enforcement 
activities. See Or. Rev. Stat. Sec.  830.362.
     Pennsylvania prohibits operation of a recreational vessel 
at any speed with a person or persons sitting, riding, or hanging on a 
swim platform or swim ladder attached to the vessel, except when 
launching, retrieving, docking or anchoring the vessel. See 58 Pa. Code 
Sec.  105.3.
    The Coast Guard is initiating this rulemaking to consider options 
to prevent CO poisoning-related casualties on all recreational vessels, 
especially existing recreational vessels that are not affected by the 
2008 EPA exhaust emission standards or by new technology for marine 
engines.

strike-related and CO poisoning-related casualties. What other State 
laws or regulations are being developed with measures to reduce or 
prevent propeller strike-related and CO poisoning-related casualties? 
Please provide any data or information from the implementation or 
development of these State regulations to assist the Coast Guard as it 
considers whether to require measures to reduce or eliminate propeller 
strike-related and CO poisoning-related casualties.
    21. What are the costs associated with implementation of the 
aforementioned State laws?

B. Specific Measures To Address Propeller Strike-Related and CO 
Poisoning-Related Casualties

    1. A possible requirement that operators of recreational vessels 
turn off the recreational vessel's engine while persons are in the 
water in close proximity to the rear of the vessel. If an operator 
turned off a vessel's engine, persons in the water behind the vessel 
would not come into contact with a spinning propeller or inhale CO 
emitted from a running engine. ``Close proximity'' would be defined as 
when a person is either touching any part of the vessel or is close 
enough to touch any part of the vessel.
    2. A possible requirement to use longer boarding ladders on new 
recreational vessels. A longer boarding ladder than what is currently 
used on most recreational vessels would make it less likely that the 
person boarding the vessel would use the lower unit in order to reach 
the ladder. As discussed above, if the propeller is spinning while a 
person is attempting to use the lower unit as a step, the person may 
either step directly onto the spinning propeller or slip off the lower 
unit of the propulsion system and fall onto the spinning propeller 
resulting in severe injuries and possibly death.
    3. A possible requirement to use boarding ladder or swim platform 
entrance gate ``interlocks'' on new recreational vessels. Ladder or 
swim platform entrance gate ``interlocks'' would prevent a recreational 
vessel engine from starting if the boarding ladder was deployed or the 
swim platform entrance gate was not closed, thus preventing a person 
using a boarding ladder or swim platform from coming into contact with 
a spinning propeller.

C. Specific Information Sought

    When responding to the questions below, please explain the 
reasoning behind your comment and provide data sources and citations.
    1. We seek comments on measure number 1 described above that would 
require operators of recreational vessels to turn off the recreational 
vessel's engine while persons are in the water in close proximity to 
the rear of the vessel. We also seek comments regarding the potential 
meaning of ``close proximity'' for this proposal and whether there 
should be exemptions to any such proposed requirement to turn the 
vessel off. Should such a proposal closely mirror the State laws 
discussed above?
    2. Are there scenarios, other than a person in the water in close 
proximity to the rear of the vessel, in which turning off the vessel's 
engine would similarly protect recreational boaters?
    3. Would there be any adverse impacts to recreational vessels, 
recreational boaters, or the recreational boating experience by turning 
off the vessel's engine when a person is in the water in close 
proximity to the rear of the vessel or in other similar scenarios?
    4. How should the Coast Guard consider the potential ``hassle 
factor'' associated with turning off the vessel's engine when a person 
is in the water in close proximity to the vessel?
    5. What is the average number of times per trip a recreational 
vessel's engine would have to be turned off because of a person in 
close proximity to the vessel?
    6. How effective would measure number 1 be in preventing accidents 
related to both propeller strikes and CO poisoning?
    7. How would the challenge to visually inspect at a distance 
whether a person is in close proximity to a vessel affect compliance 
with any turn-the-vessel-off requirements?
    8. What data or information exists that could be used to estimate 
compliance rates of measure number 1? What data

[[Page 53369]]

exists to estimate how such compliance will change during full 
implementation?
    9. We seek comments on measure number 2 described above to require 
use of longer reboarding ladders. We understand that the American Boat 
and Yacht Council (ABYC) has a proposed revision to ABYC Standard H-
41--Reboarding Means, Ladders, Handholds, Rails, and Lifelines, that 
would address longer ladders. Are there other consensus industry 
standards addressing longer ladders?
    10. What percentage of new recreational vessels are sold with a 
swim ladder installed? What percentage of existing recreational vessels 
currently have a swim ladder installed? What is the typical length of a 
swim ladder that recreational vessel manufacturers currently install?
    11. What are the costs for installation of a reboarding ladder?
    12. What data or information exists that could be used to estimate 
compliance rates of measure number 2? What data exists to estimate how 
such compliance will change during full implementation?
    13. We seek comments on measure number 3 described above to require 
use of boarding ladder or swim platform entrance gate ``interlocks'' on 
new recreational vessels. Are there any consensus industry standards 
addressing interlocks or any such standards in development?
    14. What are the costs for installation of a boarding ladder or 
swim platform entrance gate interlock system? What are the costs 
associated with maintenance of these systems?
    15. What data or information exists that could be used to estimate 
compliance rates of measure number 3? What data exists to estimate how 
such compliance will change during full implementation?
    16. What is the risk of device failures or unintended activations 
of the boarding ladder or swim platform entrance gate interlocks? What 
is the current estimated rate of unintended activations? What are the 
impacts of unintended activations? Are there any injuries or fatalities 
associated with unintended activations?
    17. What other measures or strategies would prevent propeller 
strike-related or CO poisoning-related casualties?
    18. Since the enactment of the aforementioned State laws (CA, NV, 
OR, PA, WA), has there been a change in the count and rate of CO 
poisoning-related casualties in these States? Is there any quantitative 
data, measures, metrics, studies, or other related evidence on the 
effectiveness of these State laws?
    19. Should any of the above-listed measures, or other measures or 
strategies to prevent propeller strike-related and CO poisoning-related 
casualties, be limited to specific recreational vessel types or 
lengths, or to some other criteria?
    20. Would any of the above-listed specific measures have a 
significant economic impact on a substantial number of small entities? 
What sources of data or information exist detailing the economic impact 
on small entities which may result from the use of these specific 
measures to avoid propeller strike-related and CO poisoning-related 
casualties?
