INTRODUCTION
Ocean disposal of dredged materials can affect the environment of a disposal site by
disturbing the benthic community and potentially causing long-term reduction of oxygen in
the pore waters of the sediments and the overlying waters. Natural oceanographic
processes can also be responsible for transporting disposed materials offsite into nearby
habitats.
As part of the U. S. Environmental Protection Agency (USEPA), Region 4's strategy to
monitor the effects of dredged material disposal within the marine environment, routine
surveys of the benthos and water column within and adjacent to our sites are conducted so
that their status may be assessed. In addition, the data is archived so that over time,
trends which may occur can be observed. These status and trends surveys are consistent
with the requirements of 40 C.F.R. 228.9. The present study being discussed was
conducted aboard the Ocean Survey Vessel (OSV) Bold on May 10-11, 2010.
BACKGROUND
The original Wilmington ODMDS was designated by the USEPA in August 1987. For
many years the site received both new work and maintenance material from the Federally-
authorized navigation channels of the Cape Fear River basin. In addition, new work and
routine maintenance of the Military Ocean Terminal, Sunny Point (MOTSU) has utilized
ocean dumping to satisfy disposal needs.
During the mid 1990's, the U. S. Army Corps of Engineers (USACE) determined the
need for a site with more capacity and out of the path of the required newly-aligned
entrance channel for the upcoming deepening project for the federal project. Beginning in
1998, the USEPA and USACE went about the process of finding a suitable ODMDS to replace
the site currently being used.
The process to identify, characterize and designate a new ODMDS that would
replace the original site was completed in 2002. The Final Rule promulgated to designate
the New Wilmington ODMDS went into effect in August of that year. Use of the original
Wilmington ODMDS was halted shortly thereafter.
As part of the designation process, a Site Management and Monitoring Plan (SMMP)
was developed for the New Wilmington ODMDS in 2002. Annual bathymetry surveys have
been conducted at the site by the Corps of Engineers. This monitoring effort is the first
opportunity to look at the potential impacts to the biological communities by dredging
activities. The data from the site characterization work used as part of the site designation
process is the only data to address overall changes to the benthos over time (USACE,
1999).

SURVEY AREA AND LOCATION
The study area is within and surrounding the New Wilmington, NC ODMDS located
offshore Bald Head and Oak Islands. The ODMDS is approximately 12.3 square nautical
miles (nmi) in area. Sixteen stations were selected in order to analyze the sediment grain
size, chemical, and biological characteristics of areas inside the ODMDS where disposal has
occurred, and outside the ODMDS. In addition, three (3) stations were selected to receive
water quality sampling. Depths in this area ranged from 38 to 52 feet. The ODMDS
boundary corner coordinates (NAD 27) are:
33°46'N 78°02.5'W
33°46'N 78°01.0'W
33°41'N 78°01.0'W
33°41'N 78°04.0'W
The ODMDS, survey area and station locations are shown in Figure 1.
METHODS AND MATERIALS
Method Rationale: Characterization of the benthic community and sediment
size/chemistry at selected stations, followed by analysis of community parameters via
statistical treatment, allows for identification and interpretation of changes in the
community structure. Such community statistics can be used to draw inferences regarding
perturbations to the benthic macroinvertebrate community and subsequently allow for
judgments regarding the likelihood of impact from dredged material disposal.
Sampling Stations
Sixteen stations (see Table 1 and Figure 1) were established in an attempt to
adequately sample two separate treatment areas (eight stations/treatment). The area
within the ODMDS used for disposal of dredged material was sampled as the first treatment,
and three separate areas outside the site (eastern, southern and western) were sampled as
the second treatment. Three stations were selected for water quality sampling (see Figure
1).
Water Quality
To characterize the general water quality associated with the New Wilmington
ODMDS and the surrounding area, the following water column parameters were measured:
conductivity, dissolved oxygen (DO), salinity, temperature, density, turbidity, and % light
transmission (utilizing PAR). All measurements were collected utilizing a Sea-Bird SBE 9
CTD maintained aboard the OSV Bold. Data was post processed utilizing the Sea-Bird Data
Processing Software.

Go Flow® bottles attached to the CTD/rosette frame were tripped approximately one
to three meters above the bottom and one to two meters below the surface to obtain water
samples for laboratory analyses. Once the rosette was back aboard the ship, the bottles
were emptied directly into the appropriate sample containers, labeled, and refrigerated until
demobilization. Processing and handling of water samples were according to established
Region 4 protocols (USEPA, 2007a). Laboratory analyses of the water include nutrients,
metals, PAHs, PCBs and pesticides.
Sea floor Samoling
Bottom sampling at all stations was accomplished by a minimum of two deployments
of a Young grab (surface area = 0.04 m 2; depth of 10 cm) from the stern of the ship.
After retrieval of the grab and confirmation of an adequate sample, the sediments were
removed from the grab and placed into either a pre-cleaned glass pan or dumped directly
into a stainless steel tray. The stainless steel tray was used for transfer of sediments that
would be processed for benthic macroinvertebrate identification. The glass pan was
transferred to the ship's wet lab for sediments that would be sub-sampled in order to obtain
discrete samples for sediment particle size analyses and sediment chemical analyses. All
sampling procedures and sample preservation for analyses were according to the SESD
Standard Operating Procedures (SOP), (US EPA, 2007b).
The sampling device and handling/preservative protocol for each type of sample
follows below:
Sediment Particle Size
After thorough mixing, quartering, and further mixing of the sediments in the glass
pan, a 3/4-cup mixing cup was used to scoop out the appropriate amount of sediments
needed for sediment particle size analysis. The subsamples were placed into whirl packs,
labeled, and frozen for return to the lab.
Sediment texture is determined at half-phi intervals using the ASTM method D-422 to
determine the silt-clay and sand content by combination of sieve analysis (for the +230
mesh [sand] fraction) and Boyocous (hydrometer) analysis for the -230 mesh [silt - clay]
fraction and nested sieves for larger particle fractions. Texture parameters that are
computed included percent gravel, sand, and silt /clay, median particle size, sorting
coefficient and percent moisture.
Total organic carbon (TOC) content is measured using the standard gravimetric
carbon analytical procedure carried out using a LECO induction furnace (ASTM method E-
354-97).

Sediment Chemistry
Sediment chemistry analyses were not conducted at each individual station sampled
as part of this study. Sediments from a varying number of stations were composited for
further analyses, allowing for results to be viewed on a zoned basis. In addition, the use of
composited samples allowed the study to reduce the number of samples sent back to the
laboratory without the need for excluding any part of the vast study area. Station ID's W30
- W34 were used to identify the composited sediments for laboratory analyses (see Table
2). After removal of the sediment particle size sample, the remainder of the sample was
left in the pan and covered with aluminum foil. Upon completion of sample collection at all
the stations that made up each composite, the sediments were placed into the same pan
and thoroughly mixed before transfer to the approximate sample containers.
The sample was transferred to a glass pan and thoroughly mixed. The sample was
alloquated into two 236.6 ml. glass containers and preserved by storing at 4° C until
analyzed. One container was analyzed for extractable organic compounds and the other
was analyzed for metals. Analyses for the following parameters were conducted at the
SESD lab in Athens, Georgia: heavy metals scan, extractable organic compounds (PAH's,
pesticides, and PCBs).
Benthic Macroinvertebrate Infauna
Sediments from a separate deployment of the grab were collected to obtain benthic
macroinvertebrate organisms. On-board processing involved washing the sample through a
#35 screen (0.5mm). The sample retained on the screen after washing was preserved with
100 % NoToXhisto®. Benthic containers were labeled both internally and externally and
stored for transfer to contract lab facilities. The details of sorting and identification of
infaunal taxa, as well as discussions of statistical analyses of the data, are described in
Vittor, 2010.
RESULTS AND DISCUSSION
Water Quality
The results of the water quality profiles are summarized in Table 3, and visually
demonstrated by Figures 2 and 3. All stations sampled showed the absence of any layering,
revealing that the water column throughout the entire study area was extremely well-
mixed.
Temperatures recorded ranged from 20.66 to 21.02 oc, while salinity ranged from
33.92 to 34.49 ppt (see Table 3, Figure 2).
Dissolved oxygen (DO) readings, ranging from 6.84 to 7.04 mg/L, also showed the
presence of well-mixed waters (see Table 3, Figure 3).

The results from chemical analyses of the water samples collected during this study
are provided in Appendix D (Tables D4 through D7). With the exception of iron, all other
analytes were either not detected at or above the reporting limit or the reported values
were flagged as estimates. Reported values for iron ranged from 2200 to 2400 ug/L, and
are not at levels that would cause concern.
Sea floor Samoling
After completing the bottom sampling at stations Wll and W12, it was noted that
disposal operations from the Military Ocean Terminal, Sunny Point (MOTSU) was still
ongoing. As a matter of fact, the sediments we had obtained were probably dumped within
a couple of days at the most. Although it was our intention to sample from recently
dumped dredged material, we did not want the material before enough time had elapsed to
allow for the benthic community to recover and establish equilibrium. Even the earliest
colonization of these sediments did not have sufficient time to occur. The short-term
impacts due to dredged material disposal has been well documented and was not one of
our objectives in this study. Therefore, all sediment data from stations Wll and W12 will
be excluded from our discussions. The data for these stations are being included in
Appendices B, C and E.
Sediment Particle Size
The results of the sediment particle size analyses are given in Table 4 and shown by
Figure 4. All stations were shown to be predominantly sand with mean values of 98.42 %
found inside the ODMDS and 97.12 % found outside the ODMDS. The highest reported
value for the silt/clay fraction at any station was less than 5 %.
Sediment Chemistry
The sediment chemistry showed all contaminants except for metals, to be at
or below detection limits. For the fourteen metals analyzed for, nine were detected
although copper was only detectable in only one of the five composites.
Results of metals analyses for the sediments are summarized in Table 5. As the
summarized data shows, all metals showed higher averaged values for the composites
taken from inside the ODMDS than those taken from outside the ODMDS. The reported
values for each of the individual composites are found in Table CI. A comparison of values
across the five composites shows that for most metals, W30 has a substantially higher value
than the other four composites. In fact, the other four composites seem to have very
similar values to one another.
Despite the fact that the data from stations Wll and W12 have been excluded from
discussion where feasible, the fact remains that sediments from both these stations are half
- 5 -

/ IEW WILMIIIGTOII QDMDC STATUS Al ID TF.EI IDS - MAY 20 if
the volume of composite W30. A review of the particle size data for these stations shows
that these stations had a silt/clay fraction of from 53 % to 70 %. Compared to the 0.2 %
to 4.9 % found at all other stations, it becomes apparent that contaminants of concern have
a greater chance for adsorption within the sediments at the two excluded stations. If the
opportunity had been available to chemically analyze all the stations individually rather than
compositing them, it is likely that the higher levels would only have been seen at these two
stations.
Due to the fact that none of the reported values seen at any of the five composite
stations are elevated to levels of concern, further sampling to verify the above suppositions
are not warranted.
Benthic Macroinvertebrate Infauna
The benthic infauna data is detailed and summarized in "Wilmington, North Carolina
2010 ODMDS Status and Trends Benthic Community Assessment" (Vittor, 2010). The data
from the stations collected inside the ODMDS showed the bivalve Petricola pholadiformisto
be the dominate taxon, representing 25.3% of the total number of individuals. Other
dominant taxa included the amphipod, Erichthonius brasttensis, the isopod, Edotia triloba,
and the polychaete Family, Maldanidae (LPIL), representing 7.8%, 7.3%, and 5.0% of the
total assemblage, respectively.
The dominant taxon collected from outside the ODMDS was the polychaete Family,
Capitellidae (LPIL), representing 8.7% of the total number of individuals. Other dominant
taxa included the polychaete, Mediomastus (LPIL), and the amphipods, Ampelisca
macrocephala, Oxyurostylis smithi, and Protohaustorius wigleyi, representing 7.3%, 6.3%,
5.7% and 5.1% of the total assemblage, respectively.
Taxa richness and density data for stations inside and outside the ODMDS are given
in Table 6, and summarized in Table 7. For stations inside the ODMDS, taxa richness
averaged 25.5 taxa/station (SD = 6.2), and densities averaged 2729.2 organisms/m2 (SD =
2382.7). For stations outside the ODMDS, taxa richness averaged 31.1 taxa/station (SD =
9.9), and densities averaged 2371.9 organisms/m2 (SD = 862.1). Statistical analyses
showed that there was no significant difference between stations inside and outside the
ODMDS in either taxa richness or density (see Vittor, 2010).
Taxa diversity (H1) and taxa evenness (J7) for stations inside and outside the ODMDS
are given in Table 6, and summarized in Table 7. Taxa diversity averaged 2.56 (SD = 0.41)
inside the site, and 2.83 (SD = 0.38) at those stations outside the site. Taxa evenness
inside the site averaged 0.80 (SD = 0.16), while outside the site averaged 0.83 (SD =
0.06).

The results of cluster, MDS, ANOSIM and SIMPLER analyses are discussed in detail
within Vittor, 2010. The results of both cluster and MDS analyses showed that the 14
stations fell into one of three major groups. These data indicate that there were
appreciable differences in the macroinvertebrate assemblages between stations inside and
outside the ODMDS. ANOSIM and SIMPLER analyses also showed a significant difference
between the assemblages found inside the ODMDS and those outside the ODMDS.
The fact that Cluster, MDS, ANOSIM and SIMPLER analyses indicate that significant
differences are seen between stations inside the site and those outside the site is not
alarming when one considers what aspect of the data these analyses look at. These
analyses specifically look for differences in the taxonomic makeup of each treatment. The
simple fact that stations inside the ODMDS have a different taxonomic community from the
stations outside the ODMDS does not mean that either one is better, or preferred, than the
other one. The statistical parameters (i.e., taxa richness, density) showed that, statistically
speaking, stations inside the site are just as diverse and rich as those outside the site. If
these parameters indicated that communities inside the site were statistically lower than
outside the site, a sufficient level of concern would be indicated. In such a case, a more
robust study with significantly increased numbers of replicates for both treatments would be
recommended.
CONCLUSIONS
The benthic environment of the New Wilmington ODMDS, as well as that found just
outside the site, was sampled in order to determine its status and hopefully identify possible
trends. While the present study design will not allow for any type of rigorous impact
assessment, it was designed to highlight indicators which would show whether or not a
more detailed, concentrated effort is needed.
The various parameters analyzed through this effort all indicate that, while some
significant differences were found when comparing the taxanomic make-up of the actively-
used part of the site to that which has never been used, there were no discernable
differences when comparing community statistical parameters.
In conclusion, the data collected in May 2010 shows that the benthic community of
the New Wilmington ODMDS is viable, healthy and showing no indication that any type of
adverse impact has occurred due to the dumping of dredged material.
