Site Management and Monitoring Plan

1.0	INTRODUCTION

It is the responsibility of the U.S. Environmental Protection Agency (EPA) and the U.S. Army
Corps of Engineers (US ACE) under the Marine Protection, Research, and Sanctuaries Act
(MPRSA) of 1972 to manage and monitor each of the Ocean Dredged Material Disposal Sites
(ODMDSs) designated by the EPA pursuant to Section 102 of MPRSA. Section 102(c)(3) of the
MPRSA requires development of a Site Management and Monitoring Plan (SMMP) for each
ODMDS and review and revision of the SMMP not less frequently than every 10 years. The
1996 document, Guidance Document for Development of Site Management Plans for Ocean
Dredged Material Disposal Sites (EPA/US ACE, 1996) and the EPA, Region 4 and US ACE
South Atlantic Division Memorandum of Understanding (EPA/USACE, 2007) have been used as
guidance in developing this SMMP.

A SMMP was first developed for the Fernandina Beach ODMDS in December 1998. An
addendum to the SMMP was issued in October 2001. This revision to the Fernandina Beach
ODMDS SMMP supersedes the 1998 SMMP. Upon finalization of this revised SMMP, the
SMMP provisions shall be requirements for all dredged material disposal activities at the site.
All Section 103 (MPRSA) ocean disposal permits or contract specifications shall be conditioned
as necessary to assure consistency with the SMMP.

1.1	Site Management and Monitoring Plan Team. An interagency SMMP team was established
to assist EPA and USACE in developing the 1998 Fernandina Beach ODMDS SMMP. The team
consisted of the following agencies and their respective representatives:

•	Jacksonville District Corps of Engineers

•	Florida Department of Environmental Protection - Office of Intergovernmental
Programs

•	State of Georgia

•	EPA Region 4

•	U.S. Navy

•	Fernandina Ocean Highway and Port Authority

•	National Marine Fisheries Service (NMFS)

These agencies will continue to be consulted by EPA and the USACE in revisions to the
Fernandina Beach ODMDS SMMP. The team will assist EPA and USACE on deciding on
appropriate disposal practices, appropriate monitoring techniques, the level of monitoring, the
significance of results and potential management options.

Specific responsibilities of EPA and the Jacksonville District Corps of Engineers are:

Fernandina Beach ODMDS SMMP

EPA: EPA is responsible for designating/dedesignating MPRSA Section 102 Ocean
Dredged Material Disposal Sites, for evaluating environmental effects of disposal of
dredged material at these sites and for reviewing and concurring on dredged material
suitability determinations.

USACE: The USACE is responsible for evaluating dredged material suitability, issuing
MPRSA Section 103 permits, regulating site use and developing and implementing
disposal monitoring programs.

2.0	SITE MANAGEMENT

Section 228.3 of the Ocean Dumping Regulations (40 CFR 220-229) states: "Management of a
site consists of regulating times, rates, and methods of disposal and quantities and types of
materials disposed of; developing and maintaining effective ambient monitoring programs for
the site; conducting disposal site evaluation studies; and recommending modifications in site use
and/or designation."

2.1	Disposal Site Characteristics

The designation of the Fernandina Beach ODMDS can be found in 40 CFR 228.15(h)(8). It was
designated by EPA through promulgation of a final rule on February 23, 1987, effective March
25, 1987. The Fernandina Beach ODMDS is an approximately 2 nautical mile (nmi) by 2 nmi
square area centered at the coordinates 30°32.00'N latitude and 81 ° 18.00'W longitude (NAD
27). The site coordinates are provided in Table 1.

Fernandina Beach ODMDS SMMP

The site i s 7.1 nmi (13.2 km) offshore (as measured to the center) and 11.8 nmi (21.9 km) from
the entrance to the St. Marys River. It has an area of approximately 4 nmi2 (13.7km2). Figure 1
shows the location of the Fernandina Beach ODMDS. As of 2009, it had a depth range of 37 to
69 feet (11.4 to 21.2) meters, with an average depth of 53 feet (16.2 meters). Figure 2 shows the
most recent bathymetry of the Fernandina Beach ODMDS. There is a small mound in the center
of the site with the deepest portions of the site to the southeast consisting of a north/south
oriented depression. The benthos consists mostly of sands with some areas of gravel.

2.2	Management Objectives. Appropriate management of an ODMDS is aimed at assuring that
disposal activities will not unreasonably degrade or endanger human health, welfare, the marine
environment or economic potentialities (MPRSA §103(a)). The primary objectives in the
management of the Fernandina Beach ODMDS are:

•	Protection of the marine environment;

•	Documentation of disposal activities and compliance; and

•	Maintenance of a long term disposal alternative for dredged material generated in the
Northeast Florida vicinity.

The following sections provide the framework for meeting these objectives to the extent
possible.

2.3	Disposal History and Dredged Material Volumes. The Fernandina Beach ODMDS has been
used for the ocean disposal of dredged material since 1987. Material disposed prior to 1987 was
disposed at an interim site located north of the Fernandina Beach ODMDS, near the St. Mary's
Entrance Channel. The interim site designation was canceled by the designation of the current
ODMDS on March 25, 1987. Table 2 outlines the history of disposal of material from
Fernandina Harbor and Kings Bay Entrance Channel at the Fernandina Beach ODMDS. Material
from the Kings Bay Entrance Channel is a combination of a civil works project and U.S. Navy
permitted work. Fernandina Harbor is a civil works project. A total of approximately 20 million
cubic yards of dredged material has been disposed at the Fernandina Beach ODMDS. Most of
the material is maintenance material from the Kings Bay Entrance Channel which averages
626,000 cubic yards of silty dredged material per year.

The Jacksonville District Corps of Engineers has projected disposal on the average of 600,000
cubic yards of dredged material every year from maintenance of the Kings Bay Entrance
Channel, and up to 1 million cubic yards per dredging event from the Inner Channel and Turning
Basin. Dredging from the Inner Channel and Turning Basin is infrequent. In addition, the U.S.
Navy is proposing to dispose of approximately 3.2 million cubic yards of new work dredged
material from Naval Station Mayport. Additional potential projects that could utilize the
ODMDS as a disposal site include the berthing areas adjacent to the federal project maintained
by the Fernandina Ocean & Highway Port Authority or the Fernandina Beach City Marina.

Fernandina Beach ODMDS SMMP

The U.S. Navy estimated the remaining volume of the Fernandina Beach ODMDS at 65 million
cubic yards (U.S. Navy, 2008). Although this is a rough estimate, it shows that site capacity is
not currently a concern and no disposal volume restrictions are warranted at this time. Site
capacity should continue to be re-evaluated with each review and revision to this SMMP.

2.4 Dredged Material Characteristics. The composition of dredged material dumped at the
Fernandina Beach ODMDS has consisted mostly of silty sediments as shown in Table 2 above.
Material from the project areas are described as follows: 1) Fernandina Harbor Inner Channel &
Turning Basin—predominantly gray slightly silty fine sand and gray silty fine sand; 2) Kings Bay
Entrance Channel—predominantly dark brown and brown/gray slightly silty fine brown sand with
some shells. Should new work material from deepening of Naval Station Mayport be disposed in
the site, the material would likely primarily consist of silt (41%) and clay (29%) with the
remainder consisting of sand (30%). (2008, US ACE)

The disposition of any significant quantities of beach compatible sand from future projects will
be determined during permitting activities for any such projects. It is expected that the States of
Florida and Georgia will exercise their authority and responsibility, regarding beach
nourishment, to the full extent during any future permitting activities. Utilization of any
significant quantities of beach compatible dredged material for beach nourishment is strongly
encouraged and supported by EPA. Disposal of non-beach quality sand should be planned to
allow the material to be placed so that it will be within or accessible to the sand-sharing system,
to the maximum extent practical, and following the provisions of the Clean Water Act. Disposal
of coarser material, such as boulders, should be coordinated with the local agencies, the States of
Florida and Georgia and EPA to promote possible beneficial uses of the material.

The suitability of dredged material for ocean disposal must be verified by the USACE and
agreed to (concurred) by EPA prior to disposal. Verification will be valid for three years from
the time last verified. Verification will involve: 1) a case-specific evaluation against the
exclusion criteria (40 CFR 227.13(b)), 2) a determination of the necessity for testing including
bioassays (toxicity and bioaccumulation) for non-excluded material based on the potential for
contamination of the sediment since last tested, and 3) carrying out the testing (where needed)
and determining that the non-excluded, tested material is suitable for ocean disposal.

Documentation of suitability will be completed prior to use of the site. Documentation will be in
the form of a MPRSA Section 103 Evaluation. The Evaluation and any testing will follow the
procedures outlined in the 1991 EPA/US ACE Dredged Material Testing Manual and the 2008
Southeast Regional Implementation Manual (SE RIM). This includes how dredging projects will
be subdivided into project segments for sampling and analysis. The MPRSA Section 103
Evaluation will be in the form outlined in Appendix B of the SE RIM. Water Quality
Compliance determinations should be made using the STFATE (ADDAMS) model and the input
parameters provided in Appendix A or approved modifications. Only material determined to be

Fernandina Beach ODMDS SMMP

suitable through the verification process by the USACE and EPA, Region 4 will be placed at the
Fernandina Beach ODMDS.

2.5	Time of disposal. At present no restrictions have been determined to be necessary for
disposal related to seasonal variations in ocean current or biotic activity. Dredging is typically
restricted to the winter months due to hopper dredging sea turtle restriction. During the winter,
precautions necessary to protect North Atlantic Right Whales (NARW), as described in the next
paragraph are required. It is expected that the proposed disposal activities from the deepening of
Naval Station Mayport will not occur during the NARW calving season (November 15 through
April 15) [U.S. Navy, 2009],

2.6	Disposal Technique and Route. No specific disposal technique is required for this site.
However, in order to protect NARW, disposal vessel (either hopper dredge or tug and scow)
speed and operation will be restricted in accordance with the most recent USACE South Atlantic
Division Endangered Species Act Section 7 Consultation Regional Biological Opinion for
Dredging of Channels and Borrow Areas in the Southeastern United States. In addition, the
disposal vessel's captain should be aware of the vessel approach restrictions in 50 CFR §224.103
which at the time of this SMMP prohibits approach within 500 yards of a right whale by vessel,
aircraft, or any other means.

2.7	Disposal Location. Disposal shall occur no less than 1,500 feet inside the site boundaries.
This buffer is defined by the coordinates provided in Table 3 (multiple datums and coordinate
systems are provided for completeness):

3	Surveys conducted for the Kings Bay Entrance Channel dredging are typically performed using the Georgia East Zone coordinate system

Modeling efforts have shown that this buffer will contain the initial disposal mound within the
site boundaries for projects up to 5.7 million cubic yards in situ (U.S. Navy, 2008). Projects
greater than this amount are not expected, however, if proposed, modeling will be required to
determine an appropriate buffer to contain the initial disposal mound within the ODMDS
boundaries.

Placement methods which prevent mounding of dredged materials from becoming an
unacceptable navigation hazard will be used. Dredged material shall be placed so that at no
point with depths less than -25 feet Mean Lower Low Water (m.l.l.w.) occur (i.e., a clearance of
25 feet above the bottom will be maintained). To maximize the ODMDS capacity and minimize
mounding of material, the dumps shall be scattered throughout specified disposal zones and not
place repeatedly at one location. When necessary, the Corps of Engineers in consultation with
EPA Region 4 will specify zones with the ODMDS for dredged material from each specific
ocean dumping activity. Depths at the time of disposal will be monitored to detect if adjustments
of disposal methods is needed to prevent unacceptable mounding.

Disposal shall be initiated within the disposal release zone and shall be completed (doors closed)
prior to departing the ODMDS.

2.8 Permit and Contract Conditions. The disposal monitoring and post-disposal monitoring
requirements described under Site Monitoring (section 3.0) will be included with the
management requirements described in this section as permit conditions on all MPRSA Section
103 permits and will be incorporated in the contract language for all federal projects. A
summary of the management and monitoring requirements to be included is listed in Table 4.
Template language that can be used is included in appendices (see Appendix B and C).

2.9	Permit Process. All disposal of dredged material in the ocean, with the exception of Federal
Civil Works projects, requires an ocean dumping permit issued by the USACE pursuant to
Section 103 of the MPRSA. A summary of the permitting process can be found at:
http://www.epa.gov/region4/water/oceans/Dredged Material Permit Process.htm.

2.10	Information Management of Dredged Material Placement Activities. As discussed in the
following sections, a substantial amount of diverse data regarding use of the Fernandina Beach
ODMDS and effects of disposal is required from many sources. If this information is readily
available and in a useable format it can be used to answer many questions typically asked about a
disposal site:

•	What is being dredged?

•	How much is being dredged?

•	Where did the dredged material come from?

•	Where was the dredged material placed?

•	Was dredged material dredged correctly? disposed correctly?

•	What will happen to the environment at the disposal site?

In an attempt to streamline data sharing, EPA Region 4 and USACE South Atlantic Division
have agreed on an extensible Markup Language (XML) standard for sharing of disposal
monitoring data (see also Section 3.6). Additional standards will continue to be investigated for
sharing of other disposal site related information (e.g. environmental monitoring data, testing
data, etc.).

3 .0 SITE MONITORING

The MPRSA establishes the need for including a monitoring program as part of the Site
Management Plan. Site monitoring is conducted to ensure the environmental integrity of a
disposal site and the areas surrounding the site and to verify compliance with the site designation
criteria, any special management conditions, and with permit requirements. Monitoring
programs should be flexible, cost effective, and based on scientifically sound procedures and
methods to meet site-specific monitoring needs. The intent of the program is to provide the
following:

(1)	Information indicating whether the disposal activities are occurring in compliance
with the permit and site restrictions;

(2)	Information indicating the short-term and long-term fate of materials disposed of in
the marine environment;

(3)	Information concerning the short-term and long-term environmental impacts of the
disposal.

The main purpose of a disposal site monitoring program is to determine whether dredged
material site management practices, including disposal operations, at the site need to be changed
to avoid significant adverse impacts on the marine environment.

3.1 Baseline Monitoring. Site characterization surveys of the ODMDS have been conducted by
EPA and the US ACE as part of the designation process prior to use of the site. They are
available in the designation Supplemental Environmental Impact Statement appendices A
through E. (EPA, 1986). These surveys and subsequent surveys summarized in Table 5 will
serve as the main body of data for future monitoring of the impacts associated with the use of the
Fernandina Beach ODMDS.

3.2	Disposal Monitoring. For all disposal activities, an electronic tracking system (ETS) must be
utilized. The ETS will provide surveillance of the transportation and disposal of dredged
material. The ETS will be maintained and operated to continuously track the horizontal location
and draft condition (nearest 0.5 foot) of the disposal vessel (ie. hopper dredge or disposal scow)
from the point of dredging to the disposal site, and return to the point of dredging. Data shall be
collected at least every 500 feet during travel to and from the ODMDS and every minute or
every 200 feet of travel, whichever is smaller, while approaching within 1,000 feet and within
the ODMDS. In addition to the continuous tracking data, the following trip information shall be
electronically recorded for each disposal cycle:

a.	Load Number

b.	Disposal Vessel Name and Type (e.g. scow)

c.	Tow Vessel Name (if applicable)

d.	Captain of Disposal or Tow Vessel

e.	Estimated volume of Load

f.	Description of Material Disposed

g.	Source of Dredged Material

h.	Date, Time and Location at Start at Initiation and Completion of Disposal Event

It is expected that disposal monitoring will be conducted utilizing the Silent Inspector (SI)
system for Civil Works projects [see http://si.usace.army.mil]. Disposal monitoring and ETS
data will be reported to EPA Region 4 on a daily basis utilizing the extensible Markup Language
(XML) specification and protocol per Section 3.6 regardless of the system used. EPA Region 4
and the USACE District shall be notified within 24 hours if disposal occurs outside of the
ODMDS or specified disposal zone or if excessive leakage occurs.

3.3	Post Discharge Monitoring. Bathymetric surveys will be used to monitor the disposal mound
to insure a navigation hazard is not produced, to assist in verification of material placement, to
monitor bathymetry changes and trends and to insure that the site capacity is not exceeded, i.e.,
the mound does not exceed the site boundaries. The USACE or other site user will conduct a
bathymetric survey within 60 days after disposal project completion. Surveys will not be
required for projects of less than 50,000 cubic yards. Surveys will conform to the minimum
performance standards for Corps of Engineers Hydrographic Surveys for "Other General
Surveys & Studies" as described in the USACE Engineering Manual, EMI 110-2-1003,
Hydrographic Surveying dated January 1, 2002 |"http://140.194.76.129/publications/eng-
manuals/eml 110-2-1003/toc.html. The number and length of transects required will be
sufficient to encompass the ODMDS and a 500 foot wide area around the site. The surveys will
be taken along lines spaced at 500-foot intervals or less. The minimum performance standards
from table 3-1 in Hydrographic Surveying shall be followed. Horizontal location of the survey
lines and depth sounding points will be determined by an automated positioning system utilizing
a differential global positioning system. The vertical datum will be referenced to prescribed

NOAA Mean Lower Low Water (MLLW) datum. The horizontal datum should be referenced to
the local State Plane Coordinate System (SPCS) for that area or in Geographical Coordinates
(latitude-longitude). The horizontal reference datum should be the North American Datum of
1983 (NAD 83).

3.4 Summary of Results of Past Monitoring Surveys. Surveys conducted at the Fernandina
Beach ODMDS are listed in Table 5. Although there has been a significant and relatively
constant quantity of dredged material disposed at the site, little significant change in bathymetry
has been shown. Minimum depths have only decreased by approximately two feet. Most
measurable accretion has occurred in the northern half of the ODMDS where most disposal takes
place. Limited bathymetry changes are probably due to the silty nature of the dredged material
disposed at the site. This material is probably easily removed from the site by currents and
waves. The physical properties of the substrate have changed little since designation. The
bottom remains sandy with some areas of gravel. There is no indication of any increases in any
chemical constituent in the sediments. The benthic macroinvertebrate community continues to
be dominated by polychaetes. No significant changes in the benthic macroinvertebrate
community have been observed.

Currents in the vicinity of the Fernandina Beach ODMDSs tend to have a significant tidal
component with predominate currents flowing to the north-northwest and south-southeast (see
Figure 3). There are no strong seasonal trends in the data. Surface currents exceeded 40 cm/sec
(1.3 ft/sec) five percent of the time. The median surface current at both sites was 17 cm/sec (0.6
ft/sec) whereas the median bottom current was 10 cm/sec (0.3 ft/sec). Waves in the vicinity of
the Fernandina Beach ODMDSs are out of the east-southeast. Median wave heights were 0.80
meters (2.6 feet) at the Jacksonville ODMDS and 0.78 meters (2.6 feet) at the CDIP location
north of the Fernandina Beach ODMDS. The highest measured waves were in excess of 3
meters (9.8 feet) at both sites and occurred in June. The most frequent wave period was 10
seconds. Based on linear wave theory, wave periods in excess of 4 seconds are of sufficient
length to influence bottom velocities at the depths of the ODMDS and therefore waves are likely
to affect resuspension and transport of dredged material at the ODMDS. Using the equations for
wave related shear stress, wave conditions are such that the critical shear stress would be
exceeded due to waves 89% of the time at the Fernandina Beach ODMDS. Waves are therefore
the primary factor influencing resuspension of disposed dredged material at the ODMDS,
whereas currents probably affect the direction and magnitude of transport. (EPA, 2009)

3.5	Future Monitoring Surveys. Based on the type and volume of material disposed and impacts
of concern, various monitoring surveys can be used to determine if and where the disposed
material is moving, and what environmental effect the material is having on the site and adjacent
areas.

Changes in bathymetry at the ODMDS will continue to be monitored in accordance with section
3.3. Should material from the U.S. Naval Station Mayport Homeporting Deepening Project be
placed at the ODMDS, it is recommended that a pre- and post- sediment profile imaging survey
(SPI) be conducted. SPI is a rapid reconnaissance tool for characterizing physical, chemical, and
biological seafloor processes. Material from Mayport will be significantly different than the silty
material currently being disposed at the site and should be monitored for its separate effects. The
SPI technology can be used to evaluate the effectiveness of the buffer at containing the material
within the ODMDS boundaries and away from nearby hard bottom resources. SPI technology
can also be used to document changes in grain size on the seafloor, dredged material thickness,
and the marine infaunal succession stage. Additionally, trend assessment surveys of the benthos
and water column will continue to be performed periodically (approximately every 10 years) as
resources allow. A summary of the monitoring strategies for the Fernandina Beach ODMDS and
thresholds for management actions are presented in Table 6.

Should future disposal at the Fernandina Beach ODMDS result in unacceptable adverse impacts,
further studies may be required to determine the persistence of these impacts, the extent of the
impacts within the marine system, and/or possible means of mitigation. In addition, the
management plan presented may require revision based on the outcome of any monitoring
program.

3.6	Reporting and Data Formatting.

3.6.1	Project Initiation and Violation Reporting. The US ACE or other site user should notify
EPA 15 days prior to the beginning of a dredging cycle or project disposal. The user is also
required to notify the USACE and the EPA within 24 hours if a violation of the permit and/or
contract conditions related to MPRSA Section 103 or SMMP requirements occur during disposal
operations.

3.6.2	Disposal Monitoring Data. Disposal monitoring data shall be provided to EPA Region 4
electronically on a weekly basis. Data shall be provided per the EPA Region 4 XML format and
delivered as an attachment to an email to DisposalData.R4@epa.gov. The XML format is
available from EPA Region 4.

3.6.3	Post Disposal Summary Reports. A Post Disposal Summary Report shall be provided to
EPA within 90 days after project completion. These reports should include: dredging project
title; permit number and expiration date (if applicable); contract number; name of contractor(s)
conducting the work, name and type of vessel(s) disposing material in the ODMDS; disposal
timeframes for each vessel; volume disposed at the ODMDS (as paid in situ volume, total paid
and un paid in situ volume, and gross volume reported by dredging contractor), number of loads
to ODMDS, type of material disposed at the ODMDS; identification by load number of any
misplaced material; dates of pre and post disposal bathymetric surveys of the ODMDS and a
narrative discussing any violation(s) of the 103 concurrency and/or permit (if applicable). The
narrative should include a description of the violation, indicate the time it occurred and when it
was reported to the EPA and USACE, discuss the circumstances surrounding the violation, and
identify specific measures taken to prevent reoccurrence. The Post Disposal Summary Report
should be accompanied by the bathymetry survey results (plot and X, Y,Z ASCII data file), a
summary scatter plot of all disposal start locations, and a summary table of the trip information
required by Section 3.2 with the exception of the disposal completion data. If all data is
provided in the required XML format, scatter plots and summary tables will not be necessary.

3.6.4	Environmental Monitoring. Material tracking, disposal effects monitoring and any other
data collected shall be coordinated with and provided to SMMP team members and federal and
state agencies as appropriate. Data will be provided to other interested parties requesting such
data to the extent possible. Data will be provided for all surveys in a report generated by the
action agency. The report should indicate how the survey relates to the SMMP and previous
surveys at the Fernandina Beach ODMDS and should provide data interpretations, conclusions,
and recommendations, and should project the next phase of the SMMP. Monitoring results will
be summarized in subsequent modifications to the SMMP.

4.0 MODIFICATION OF THE FERNANDINA BEACH ODMDS SMMP

Should the results of the monitoring surveys or reports from other sources indicate that continued
use of the ODMDS would lead to unacceptable effects, the ODMDS SMMP will be modified to
mitigate the adverse impacts. The SMMP will be reviewed and revised at a minimum of every
ten years. The SMMP will be reviewed and updated as necessary if site use changes
significantly. For example, the SMMP will be reviewed if the quantity or type of dredged
material placed at the site changes significantly or if conditions at the site indicate a need for
revision.

[USE LANGUAGE BELOW FOR SI PROJECTS]

3.3.6.3 Silent Inspector - Special Standard of Responsibility
3.3.6.3.1 General

The Silent Inspector (SI) is an automated dredge contract monitoring system comprised
of both hardware and software developed by the Army Corps of Engineers (the Corps).
The Corps developed the SI as a low cost, repeatable, impartial system for automated
dredge monitoring. The SI systems integrate various automated systems to record digital
dredging and disposal activities in real-time on a 24 hour/7 days a week basis.
Information is recorded to the on-board computer where it is available to the Corps
Quality Assurance Representative (QAR) for examination and for periodic download and
transmittal via an automated email service for inclusion in the SI database. The dredging


-------
contractor supplies and owns the on-board system and all associated sensors. Additional
information about SI and SI specifications can be found at http://si.usace.army.mil.

3.3.6.3.2	Requirement

As authorized by FAR 9.104-2, Contracting Officers may establish special standards of
responsibility when necessary. The Contracting Officer has determined that use of the SI
is necessary for work performed by hopper dredge and disposal scows. Therefore, in
order to be considered responsible for performing this contract, the Offeror must establish
prior to contract award that any hopper dredge or disposal scows to be used in
performance of this contract has been outfitted with the SI system and the system has
been certified by the Engineer Research and Development Center (ERDC) within the last
year. Disposal scows shall utilize the monitoring or TDS profile. Questions regarding
certification should be addressed to the SI support team at 601-634-2923.

3.3.6.3.3	Data Submissions

Scow data shall be transferred by the contractor automatically to the SI database on
intervals not to exceed 24 hours. Hopper dredged data shall be transferred in accordance
with the Hopper Dredge Specifications found at http://si.usace.army.mil.

3.3.6.4 Misplaced Materials

Materials deposited outside of the disposal zone specified in 3.3.3 will be classified as
misplaced material and will result in a suspension of dredging operations. Redredging of
such materials will be required as a prerequisite to the resumption of dredging unless the
Contracting Officer, at his discretion, determines that redredging of such material is not
practical. If redredging of such material is not required then the quantity of such
misplaced material shall be deducted from the Contractor's pay quantity. If the quantity
for each misplaced load to be deducted cannot initially be agreed to by both the
Contractor and Contracting Officer, then an average hopper/scow load quantity for the
entire contract will be used in the determination. Misplaced loads may also be subject to
penalty under the Marine, Protection, Research and Sanctuaries Act. Materials deposited
above the maximum indicated elevation or outside of the disposal area template shown
will require the redredging or removal of such materials at the Contractor's expense. In
addition, the Contractor must notify the Contracting Officer and the Environmental
Protection Agency Region 4's Wetlands, Coastal and Oceans Branch (61 Forsyth Street,
Atlanta, GA 30303) within 24 hours of a misplaced dump or any other violation of the
Site Management and Monitoring Plan for the Fernandina Beach ODMDS. Corrective
actions must be implemented by the next dump and the Contracting Officer must be
informed of actions taken.
