## 3.0 BACKGROUND INFORMATION

The EPA and the USACE have determined that the existing Jacksonville ODMDS has a remaining capacity of 2 million cubic yards of dredged material from the proposed deepening of Mayport Naval Station and eight years of continued maintenance of Mayport Naval Station and the St. Johns River Entrance Channel. Based on potential increases in maintenance volumes and a deepening project at Jacksonville Harbor currently under study, the USACE has determi ned that the existing Jacksonville ODMDS may reach capacity as early as 2013. EPA and the USACE are therefore initiating the process for either expanding the existing Jacksonville ODMDS or designating a new ODMDS offshore Jacksonville, Florida.

An initial reconnaissance survey was conducted in October 2009 and followed by a second reconnaissance survey in March 2010. Based on results of those surveys, three candidate sites have been identified, one north of the entrance channel and two to the
south.



## 4.0 SUMMARY OF SCIENTIF IC ACTIVITIES/ OBSERVATIONS

The survey consisted of epibenthic trawls, s ediment sampling for sediment chemistry, physical properties and macroinfauna analysis, and water column profiles. Trawls were conducted in the morning and evening periods and water column profiles were taken at each station during an ebb and flood tide. Dive operations were also conducted to ground-truth previous survey sidescan sonar data. Use of the Sediment Profiling Camera (SPI) was attempted, but malfunction of the camera occurred after the completion of two stations. A summary of activities is provided in the table below:

## 5.0 SUMMARY OF RESULTS COMPLETED DURING SURVEY

103 drops of the sampler were required to obtain 14 sediment chemistry/physical samples and 54 macroinfauna samples. Sediment samples are summarized in Table 1 attached. 26 epibenthic trawls were conducted. The trawl locations are provided in Table 2 attached. 14 CTD casts were conducted. The locations are provided in Table 3 attached. Six dives were completed. A summary of the dive operations is attached. Figures showing the sediment samples, trawl locations and dive sites are attached.



## 6.0 LIST, COMPLETION DATES, AND DISCUSSION OF PENDING ANALYSIS

Pending analysis includes:

• Chemical analysis of sediments

• Physical analysis of sediments

• CTD post processing

• Tabulation of macroepifaunal data

• Macroinfauna analysis

All analysis is expected to be completed and included in an interim report by July 30,

2010.



## 7.0 PROBLEMS ENCOUNTERED

The SPI camera malfunctioned after the second station. The strobe would not fire resulting in a blank image. The cause of the malfunction is still undetermined.Survey Report: New Jacksonville ODMDS Spring Designation Survey May 2010

## 8.0 ACHIEVEMENT OF SURVEY OBJECTIVES

All primary survey objectives were achieved. Supplementary additional trawls were completed. The secondary objective of conducting SPI sampling was not achieved.



## 9.0 PRELIMINARY ENVIRONMEN TAL MANAGEMENT DECISIONS FROM SURVEY

The purpose of this survey was to characterize candidate disposal sites. Therefore, there are no decisions to be made until all studies are completed.



## 10.0 RECOMMENDATIONS FOR OSV BOLD IMPROVEMENTS

None



## 11.0 CONTRACTOR SUPPORT EVALUATION

ANAMAR Environmental Consulting suppor t was excellent. No problems/issues were encountered. The support from the Fl orida Museum of Natural History was very much appreciated.

OSV Bold contractor support was excellent.

## 13.0 FINAL REPORTING PLANS
ANAMAR Environmental Consulting for the USACE Jacksonville District will produce a final site designation study report following the completion of the summer/fall survey. The report will be used in the development of an Environmental Impa ct Statement for the designation of a new or expanded Jacksonville ODMDS.Survey Report: New Jacksonville ODMDS Spring Designation Survey May 2010
