2009 EPA Diving Safety Board Meeting
The 2009 EPA Diving Safety Board meeting was held at the National Oceanographic and
Atmospheric Administration facility at Key West, Florida, November 16-20, 2009. All dive units
were represented. Agenda items included:
•	Discussion of NOAA fatality in Dry Tortugas, and policy implications to NOAA and the
scientific diving community;
•	Safety, Health, and Environmental Management Division managers (Division Director,
Branch Chief, and DSB rep) led discussions on dive program elements, including risk
management, training, and medical surveillance;
•	Discussion on "Scientific Exemption" clause as it applies to EPA;
•	Revisions to the EPA Diving Safety Manual;
•	Review of training needs; and
•	Approval of Unit Diving officers at the Western Ecology Division, in Corvallis, OR, and
EPA Region 10 Headquarters, in Seattle, WA.
Training
The Gulf Breeze Diver Training Center conducted its annual Diver Training Program on
May 12-16, 2009. Forty-two EPA personnel were involved in training or instructing. Seventeen
certifications were given for Scientific Diver. Four Divemasters were also certified. The program
offered training in the use of dry suits, AGA masks, EXO-26 mask, Superlite-27 diver's helmet,
surface-supplied air and NITROX , surface communications, wireless communications, U/W
sonar, lift bags, U/W metal detector, U/W search and recovery, use of U/W tools, Diving
Accident Management, and oxygen enriched air certification. EPA divers gained experience by
working as operational diver instructors during the water exercises. Some of the more
experienced divers lectured on their areas of experience.
Reciprocity:
EPA participates in joint diving activities with a variety of outside organizations. These can
include other Federal and State agencies, universities, and private sector organizations. To
facilitate these operations and to ensure safety, formal Reciprocity Agreements are established
with these entities, based upon approved standards. These agreements are maintained for the
calendar year, and can be renewed annually as needed. In 2009, EPA established Reciprocity
Agreements with:
•	U. S. Department of Commerce, National Oceanic and Atmospheric Administration
•	U. S. Fish and Wildlife Service
•	U. S. National Park Service
•	State of Alaska, Department of Fish and Game
•	State of Florida, Department of Environmental Protection

Program Collaboration and Support
Review of U.S. Antarctic Scientific Diving Program
In 2009, Kennard Potts was asked to participate in a review the National Science Foundation's
United States Antarctic Program (USAP) Scientific Diving Program. As with EPA, the USAP
conducts diving operations under the "Scientific Diving Exemption". This review was conducted
under the scope of scientific diving as defined by the OSHA regulations.
The review considered policy and program management and aspects of operations and training.
This external review was derived from two activities: (1) attendance at the annual meeting of the
USAP Scientific Diving Control Board (SDCB) and (2) a site visit to McMurdo Station,
Antarctica, to observe diving operations, interview divers and support staff, and assess emergency
procedures/hyperbaric chamber treatment facilities. The annual meeting of the SDCB was held in
Washington, DC, at the Smithsonian Institution on July 27, 2009. The on-site review of dive
operations was conducted at McMurdo Sound Station, Antarctica and three dive sites near
McMurdo Station, during October 19 - November 2, 2009.
Observation of multiple dives at three dive sites near McMurdo Station comprised the on-site
review of dive operations. Additionally, a visit was made to a remote dive site at near McMurdo,
called Lake Louise. The McMurdo Station dive locker and associated facilities were also
evaluated, as was the hyperbaric chamber attached to the McMurdo medical clinic.
This evaluation considers three areas of interest:
1.	Policy and Management,
2.	Operational Aspects and,
3.	Training
The final report was submitted to the National Science Foundation in December 2009.

lab. The GED dive team accounted for a total of 453 individual dives in 2009.
Many of these dives were performed in collaboration with other EPA units and
were included in the total number of dives.
Training Dives:
11

-------
GED divers made inspection dives around the GED west dock to search and
remove any hazards. Ladders were removed, cleaned, and reinstalled. Barnacles,
oysters, and fishing gear were removed from the pilings. Dives were made in
order to test equipment (Superlite- 27, wireless, hard wire, EXO-26, a multitude
of Aga masks and regulators) during the year.
Coral Condition Survey:
EPA Divers collected coral reef condition data and photographed corals off St.
Thomas, St. John, and the Dry Tortugas. All of these operations were in
collaboration with other units within EPA's Diving Program. The Program's
overall goal is to estimate biological conditions of coral populations, and to
understand associations between coral reefs, reef fish, soft corals, and other
macro-biota
Divers completed the following:
•	Located underwater stations.
•	Enumerated the number and species of coral colonies located along a 25 meter
transect.
•	Estimated class size for each coral colony along the transects.
•	Enumerated reef fish and calculated the available biomass.
•	Characterization of Octocorals, gorgonians, macroinvertebrates, and
substrates were performed.
•	Photographed representative samples of each class size for computerized
determination of surface area and living tissue.
•	Conducted disease and bleaching surveys.
•	Assessed the percentage of living/dead, size class, imaging, disease frequency,
bleaching and numbers of coral colonies via transect surveys.
•	Mapped and videotaped the sites and diseased corals.
ADCP (Acoustic Doppler Current Profiler) Deployment and Service:
GED divers assisted in the deployment of an environmental monitoring buoy,
water quality sondes, and ADCP in Escambia Bay under zero visibility
conditions. The ADCP was retrieved, downloaded, cleaned, and returned to the
station on a bimonthly basis.
Assistance to other Regions and Agencies:
GED divers assisted in the scientific endeavors of Region 4 on the Tampa
ODMDS site. They also assisted The Nature Conservancy with coral surveys in
the Dry Tortugas.

7. Region 6 - Dallas, TX
A. Dive Activities
The Region 6 dive team cooperated with the Regional Superfund Division in the
planning of a regional disaster exercise in Oklahoma. The exercise was
conducted in November 2008, and consisted of deployment of field resources to
the site of a simulated tornado. Several issues that would require the evaluation
of underwater locations were considered by the regional dive team. Region 6
coordinated with ERT and arranged for their participation and the inclusion of
ERT surveillance equipment, including the ROV and sonar equipment. The dive
team was prepared for the exercise when a real hurricane intervened, and the
entire exercise was cancelled.
Region 6 divers were invited to assist the Region 4 program on two separate
occasions. Two Region 6 divers deployed with Region 4 onboard the OSV Bold
on the November 13, 2008 to survey the Tampa Banks, and on the May 15, 2009
survey to the Flower Garden Reef survey. Heavy weather precluded any diving
activity whatsoever during the November survey. Heavy weather severely
impacted the Flower Garden survey as well. Only four dives were performed by
Region 6 divers during the Flower Garden survey. Diver activities included
surveying the reef for the presence of invasive species of orange cup corals.
Operations were conducted from rigid hull inflatable boats deployed from the
OSV Bold

8. Region 10 Dive Unit-Seattle, WA
A. Dive Activities:
During FY09, Region 10 had eight work diving "events", consisting of 11
separate diving mobilizations. There were four dive training activities and three
projects performed in support of Superfund remediation sites. Five projects were
related to natural resource, water, or habitat quality issues. Five events employed
tether diving. Region 10 had 63 work dives and 39 training dives, for a total of
137 dives (including requalification and proficiency dives).
14

-------
During FY2009, Region 10 (RIO) had the following work projects:
•	Squaxin Passage, South Puget Sound, WA - October 2008: The team
performed an Acoustic Doppler Current Profile meter (ADCP) search and
recovery for Washington State Department of Ecology (WDOE).
•	Mouth of Duwamish River, Elliot Bay, WA - February 2008: Assisted the
RPM by determining whether solid phase microextraction (SPMEs) sampling
devices can be deployed to the desired depth in the sediment beneath the
existing cap, in areas identified by the Army Corp of Engineers.
•	Dive support was provided for the Washington State Department of Natural
Resources. Region 10 divers performed reconnaissance and information
collection on abandoned vessels in Sinclair Inlet, WA, in February 2008. The
survey determined potential threats to habitat and the release of hazardous
material.
•	Region 10 conducted a Superfund site habitat assessment at an old log
handling and treatment facility at Quendall Terminal, at the south end of Lake
Washington, WA, during April and May 2009. The assessment characterized
the benthic habitat, noting wood and other debris in areas of a known
groundwater plume and creosote contamination. Divers used seepage meters
to detect groundwater upwelling. A video documentation looked for invasive
species, such as milfoil.
•	Region 10 performed a study on the exposure and effects of complex mixtures
(PCBs and PAHs) in the estuarine environment, at Lower Duwamish River
Waterway, WA. Sediment, surface water, and groundwater samples were
collected.
•	The Region 10 Dive unit characterized the hard-bottom habitat identified
during the June 2008 OSV BOLD sidescan surveys on ocean dredged material
disposal site, in the Pacific Ocean, off the Chetco River, Brookings, OR,
during August 2009.
•	The Washington Department of Ecology requested assistance to recover a
Hydrolab unit that was lost in 75' of water at Pierre Lake, WA, in September
2009.
Training:
•	Nov. 2008 - The team practiced standard dive skills at the NOAA training
facility. Skill sets involved buoyancy, dry suit blow-up, test of splits fins,
wireless communications proficiency, compass use, safe ascent and descent.
15

-------
A rescue drill was also conducted. Requalification dives for three divers were
also performed.
•	Jan. 2009 - The team practiced with scientific data collection gear, wireless
communications, and diver rescue drills, at the NOAA training facility. Diver
rescue drills included bringing an unresponsive diver from the bottom to the
surface, diver tow to the dive platform, securing on a backboard after gear
removal, 02 administration, AED usage, standard emergency contact
procedures throughout the drills.
•	Feb. 2009 -Divers tested and performed troubleshooting for our OTS wireless
communication equipment at the Underwater Sports pool.
•	June 2009 - The team practiced video and wireless communications at the
NOAA training facility. One member completed specific work/science dive
skill tasks for EPA certification as a scientific diver.
•	First aid training was held in October 2008, for all divers and boat operators.
•	Two divers attended the week-long diver rescue course at the Catalina
Hyperbaric Chamber in October 2008.
•	Sean Sheldrake completed a NOAA refresher on his ship-board medic/DMT
training in January 2009.
•	Several divers and boat operators took an expanded version of the Washington
State Boat Operators' course that is accredited and accepted by the USCG.
•	In February 2009, Region 10 divers took the DAN 02 administration and
diver malady course taught by our in-house DAN instructor. This course
included a CPR/AED refresher.
•	Sean Sheldrake also participated in Gulf Breeze dive training as the lead
Divemaster instructor.
•	Region 10 continued its AAUS presence this year by presenting a paper on
diver exposure in polluted water.
Additional training needed:
In 2010, the usual refreshers for CPR/AED and first aid, and eight hour health and
safety are required annually (or biannually) for some first aid courses. In
addition, surface supply training is planned. Though most R10 divers have
extensive surface supply experience, a course will be offered to ensure our newer
divers start with the same base of knowledge.

9. Western Ecology Division (WED): Corvallis, OR
A. Dive Activities
Dive activities during 2008-2009 consisted of proficiency, training (freshwater)
and working dives to study eelgrass beds, collect samples, and test out new
equipment. Working dives included photographs of a prototype fish trap,
collecting eelgrass samples; maintaining underwater data logging equipment; and
collecting whole eelgrass plants. Proficiency dives were performed as needed.
Four WED divers completed a NAUI Rescue Diver training course. One WED
diver is involved with the Oregon Coast Aquarium and conducts dives to help
with aquarium maintenance on a monthly basis.
Locations of work dive operations: Yaquina Bay, Oregon

-------
WED lost a dive team member due to a heart attack at work. Pete Eldridge died
in his office on October 7th after resuscitation attempts were unsuccessful. The
event was especially tragic since the day he passed away, Pete had spent the
morning undergoing his annual dive exam in Corvallis. After returning to
Newport (~ 1 hr drive from Corvallis), he complained of chest pains, and went to
a second physician who concluded the pains were insignificant and probably the
result of indigestion. Late in the afternoon on the same day, Pete returned to his
office and subsequently collapsed.
This incident was particularly disturbing since regular dive exams were unable to
identify Pete's heart condition, even on the day he passed away. The WED dive
program is considering having divers undergo a regular stress EKG instead of a
resting EKG to help identify potential cardiac problems in the future. WED is
interested in learning more about the specifics of what other programs do, so they
can avoid another tragedy of this sort.
Training:
Two WED divers became certified as oxygen Instructors by DAN, and can
provide the dive team with oxygen administration refresher training on a regular
basis. In addition, two divers have been trained as instructors for First Aid/CPR
and marine life injuries, as well as AED use and protection against blood borne
pathogens.

Donald Wade Lawhorn (August 24,1938 - May 31, 2010)
The EPA dive community lost one of the founders of the dive safety program in 2010.
Don Lawhorn was an active participant in the development of the EPA diving program
and a member of the first joint training session aboard the EPA Ocean Survey Vessel -
Peter W. Anderson, in 1980. He contributed to the program's development until
retirement.
Don served in several positions during his dive career: Scientific Diver, Divemaster, and
member of the EPA Dive Safety Board. He was elected as Chairman of the EPA Dive
Safety Board in 1988 and served in that position until 1993. Don served in the U. S.
Coast Guard, active and reserve, from 1979 through 1996. Don worked at the EPA
Athens Laboratory and retired in 1995.
Don died Monday, May 31, 2010, while at St. Mary's Hospice in Athens, Georgia, after a
prolonged battle with cancer.
Peter M. Eldridge (March 19,1946 - October 7, 2008)
Pete was a member of the Western Ecology Division lab dive team, in Newport, Oregon.
Pete was born in West Hartford, Connecticut, and followed a lifetime of study and work
in marine science. He received a BA in Biology and Chemistry at Southampton College,
Southampton, NY, a MS in marine science from Long Island University, and a Doctorate
