u) i\ monuc rio\
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 no 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, 2017) have been used as guidance in
developing this SMMP.
A SMMP was originally developed as part of the designation process and was published in
November 2004 as part of, Final EIS for Designation of the Palm Beach Harbor Ocean Dredged
Material Disposal Site and the Port Everglades Harbor Ocean Dredged Material Disposal Site,
(EPA, 2004). The original SMMP was revised in May 2009.
These SMMP provisions shall be requirements for all dredged material disposal activities
associated with the Port Everglades ODMDS. All MPRSA Section 103 ocean disposal permits or
contract specifications shall be conditioned as necessary to assure consistency with the SMMP in
order to uphold the MPRSA.
1,1 Site Management and Monitoring Plan Team
An interagency SMMP team was established to assist the EPA and USACE in developing the
initial (2004) Port Everglades ODMDS SMMP. The team consisted of the following agencies
and their respective representatives:
Jacksonville District USACE
EPA Region 4
Port of Port Everglades
State of Florida (Coastal Zone Management Office)
National Oceanographic and Atmospheric Administration (NOAA)
U.S. Coast Guard, Station Fort Lauderdale
These agencies will continue to be consulted in revisions to the Port Everglades Harbor ODMDS
SMMP.
Specific responsibilities of the EPA Region 4 and the Jacksonville District Corps of Engineers
respectively are as follows:
The EPA is responsible for designating/de-designating, management of, evaluating
environmental effects of disposal of dredged material at these sites, and for reviewing and
U.S. EPA Region 4 / USACE Jacksonville District

Port Everglades Harbor ODMDS SMMP
May 2020
concurring, concurring with conditions, or not concurring on dredged material suitability
for ocean disposal determinations of MPRSA Section 102 Ocean Dredged Material
Disposal Sites.
The USACE is responsible for evaluating dredged material suitability, issuing MPRSA
Section 103 permits, regulating site use and developing and implementing project
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." This plan may be modified if it is determined that such changes are
warranted as a result of information obtained during the monitoring process, in order to properly
manage the site per MPRSA §103(a)).
2.1 Disposal Site Characteristics
The regulatory designation language for the Port Everglades Harbor ODMDS can be found in
40 CFR Section 228.15(h)(22). The western edge of the Port Everglades Harbor ODMDS (figure
1) is located 4 nautical miles (nmi) offshore and the site is 1 nmi by 1 nmi in size (1 nmi2). As of
2017, it had a depth range of-195 to -225 meters (-640 to -761 feet), with an average depth of
207 meters (-678 feet). The site is centered at approximately 26°07.00'N latitude and
80°01.50'W longitude (NAD 83) or state plane coordinates 649292.4 ftN and 976098.2 ft E
(NAD83). The site coordinates are as follows:

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 Port
Everglades Harbor 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
Port Everglades, Florida vicinity.
The following sections provide the framework for meeting these objectives.
2.3 Disposal History and Dredged Material Volumes
The Port Everglades Harbor ODMDS is intended to be used for the disposal of dredged material
from maintenance projects, or those new work projects less than 500,000 cubic yards, from the
greater Broward County, Florida vicinity. The primary user of the Port Everglades Harbor
ODMDS is the USACE for the Port Everglades Federal Navigation Project, including material
from the Entrance Channel, Main, North, and South Turning Basins, South Access Channel and
the Turning Notch. Secondary users are the Port Everglades Port Authority and Broward County,
including material from the South Turning Basin beyond Civil Works authorized depths, Port
Slips, Port Berthing Areas, and the Sand Bypass project. The U.S. Navy and U.S. Coast Guard
also have facilities in the area that may require use of the ODMDS, although no need has
currently been identified.
Historically, a site approved for ocean dumping on an interim basis (interim MPRSA disposal
site) located approximately 1.6 nautical miles from shore was used for ocean disposal of dredged
material from Port Everglades Harbor; use of this site was discontinued in the 1980s due to
concern that material drifted back onto the nearby reef. This former site has been documented to
contain various amounts of man-made debris including concrete pilings, steel and concrete
frameworks, and tires (Messing, 2003) of unknown origin making it unacceptable for dredged
sediment disposal as it no longer meets environmental criteria.
Due to the lack of an ODMDS in the vicinity of Port Everglades after the interim site was
discontinued, the EPA designated the Port Everglades Harbor ODMDS in 2005 approximately
4.3 nmi offshore. The ODMDS, 1 nmi2 in size, was designated to accommodate dredged
material from periodic maintenance events from the Port Everglades Harbor. The Jacksonville
District Corps of Engineers estimated an annual average disposal rate of approximately 30,000
cubic yards of material. Maintenance occurs only as needed. In 2005, 46,686 cubic yards of
dredged material from Port Everglades Harbor was disposed of in the ODMDS, and in 2013,
413,932 {in situ) cubic yards of dredged material was disposed of in the site (USACE, 2013).
Maintenance volumes from the Port Everglades Federal Navigation Project are not expected to

significantly increase and are expected to average approximately 300,000 cy over a ten-year
period. Maintenance events are listed below, since the 2005 designation.
Table 2. Dredged Material Disposal Projects placed into the ODMDS (2005-2013)

ODMDS (-195 to -225 meters) makes future recovery of any disposed materials extremely
unlikely.
2.4.4 Dredge Material Quality Verification
The suitability of dredged material for ocean disposal must be verified by the USACE and
agreed to via written concurrence from the EPA prior to disposal per the MPRSA. Concurrence
on the suitability of material for ocean disposal will be valid for no more than three years.
Verification process:
1) Case-specific evaluation against the exclusion criteria (40 CFR 227.13(b))
2) Determination of testing requirements for non-excluded material based on the potential of
sediment contamination since last verification.
3) When applicable, execute testing and determination of suitability of non-excluded
material for ocean disposal.
Documentation for suitability will be completed and concurred upon by the EPA prior to use of
the Port Everglades Harbor ODMDS. Documentation will be in the form of a MPRSA Section
103 Evaluation. Potential testing and the evaluation will follow the procedures detailed in a
Sampling and Analysis Plan as outlined in the 1991 EPA/USACE Dredged Material Testing
Manual (Greenbook) and Southeast Regional Implementation Manual (SERIM) or the
appropriate updated versions thereof. This includes how dredging projects will be subdivided
into project segments for sampling and analysis and how testing is to be performed. The MPRSA
Section 103 Evaluation will be in the form outlined in Appendix C of the SERIM. Water Quality
Compliance determinations will be made using the STFATE (ADDAMS) model and the input
parameters provided in Appendix A of this document. Only material determined to be suitable
through the verification process by the USACE and the EPA will be placed at the Port
Everglades Harbor 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. As monitoring results are compiled, should any
such restrictions appear necessary, disposal activities will be scheduled to avoid adverse impacts.
Additionally, if new information indicates that endangered or threatened species are being
adversely impacted, restrictions may be imposed.
Transportation of dredged material shall only be allowed when weather/sea state conditions and
scow loading level will not interfere with safe transportation and will not create risk of spillage,
leak, or other loss of dredged material during transit. Transportation for the purposes of ocean
dumping begins when the vessel is full and begins transiting to the ODMDS.
2.6 Disposal Technique
Transit to the ODMDS begins as soon as dredged material loading into the disposal vessel is
completed and the vessel begins moving to the ODMDS. While in route to the ODMDS, the
U.S. EPA Region 4 / USACE Jacksonville District
Page 11
-------
Port Everglades Harbor ODMDS SMMP
May 2020
disposal vessel must remain within the navigation channel while west of the sea buoy (G"3"). No
dredged material shall be leaked or spilled from vessels while west of the sea buoy. Leakage or
spillage of material east of the sea buoy is limited to 1.5 feet of draft loss (average between
forward and aft sensors) during transit to the ODMDS. All appropriate measures to avoid
spillage during transit must be taken. Disposal shall be initiated within the specified disposal
release zone and shall be completed (doors closed or verified release of all material) prior to
departing the ODMDS. When dredged material is disposed, no portion of the disposal vessel
shall be outside of the boundaries of the Port Everglades Harbor ODMDS. Appropriate
measures to avoid violations may include but are not limited to: up-to-date U.S. Coast Guard
and/or American Bureau of Shipping certification of all disposal-related vessels; maintenance
(inspection and/or replacement) of gaskets on barge doors; pre-transit testing of barge door
hydraulics; pre-transport verification of appropriate weather/sea state conditions; and verification
of disposal zone. Standard surveillance and evasive measures to protect sea turtles and marine
mammals shall also be employed during all disposal operations at the Port Everglades Harbor
ODMDS, as provided in the South Atlantic Regional Biological Opinion from National Marine
Fisheries Service (2020).
2,7 Disposal Location
40 CFR §227.28 requires that disposal occur no less than 330 feet (100 meters) inside the
designated site boundaries. A release zone has been established to satisfy this criterion as well as
manage dredged material disposal and contain impacts to within the ODMDS boundaries. The
release zone is described below in Table 3.

2.8 Permit and Contract Conditions
The disposal monitoring and post-disposal monitoring requirements described under Site
Monitoring will be included as permit conditions on all MPRSA Section 103 permits and will be
incorporated in the contract language for all federal projects. Template language that can be used
is included in appendices (see Appendix C and D).
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. Permitting procedures are outlined in 33 CFR Parts 320, 324 and 325. Additional
U.S. EPA Region 4 / USACE Jacksonville District

guidance is available in the SERIM.
3.0 SITE MONITORING
The MPRSA establishes the need for including a monitoring program as part of the Site
Management and Monitoring Plan. Site monitoring is conducted to ensure the environmental
integrity of a disposal site and the areas surrounding the site. Compliance with the site
designation criteria, any special management conditions, and permit requirements is also verified
via monitoring. 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. A monitoring program, under MPRSA, also establishes an
empirical basis for site designation/de-designation, assesses trends in environmental condition
changes due to dredge disposal operations, determines if dumping shall be prohibited (MPRSA
103((c)(2)), and supports future modifications to site management and monitoring plans as
required under MPRSA 102(c)(3).
3.1 Baseline Monitoring
Site characterization surveys of the ODMDS were conducted by EPA and the USACE as part of
the designation process and by EPA for monitoring purposes after designation. Results from
these surveys were used to monitor potential impacts associated with use of the Port Everglades
Harbor ODMDS. The results of investigations presented in the designation FEIS (EPA 2004) and
the draft Environmental Assessment for the Expansion of the Port Everglades Harbor ODMDS
(EPA, 2020) and subsequent surveys are listed in Table 4 and serve as the main body of data for
the monitoring of the impacts associated with the use of the Port Everglades Harbor ODMDS. In
addition, a baseline hard-bottom habitat study will be conducted prior to use of the expanded
portion of the ODMDS for disposal of new work material.

Dredged material formed an elliptical deposit on the
seafloor with the upper half of the elliptical deposit
occurring to the north of the disposal site. The main
physical change resulting from disposal appeared to be
a subtle shift in sediment texture. Overall, at the
majority of stations within the dredged material
footprint and in surrounding areas, it did not appear
that there had been any adverse changes in oxygen
demand, redox state, or other geochemical properties
as a result of disposal. Local benthic communities are
rapidly recolonizing the sandy dredged material that
had been deposited at the Port Everglades Harbor
ODMDS and are at an intermediate stage of
recolonization. The release zone was moved in 2009 to
keep future disposal deposits within the ODMDS
boundaries.

The revised release zone was effective at containing
almost all of the dredged material disposal impact
within the ODMDS boundaries. Only one station (50
meters south of the ODMDS) had any measurable
amount of dredged material in excess of 5 cm.
The sea star Coronaster briareus, a species managed
by the SAFMC, was the only species to show a benthic
habitat preference being almost twice as abundant on
unconsolidated soft sediment dredged material relative
to native soft sediment and dredged material hard
carbonate bottoms. Given the estimated successional
stage, OSI, and high level of bioturbation, it appeared
that infaunal communities have successfully
recolonized the dredged material within 17 months of
completion of the 2013 disposal event.

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
(accuracy± 0.1 foot) of the disposal vessel (i.e. hopper dredge or disposal scow) from the point
of dredging or loading to the disposal site and return to the point of dredging or loading. Data
shall be collected at least every 0.25 nautical mile or every 4 minutes during travel to and from
the ODMDS and every 12 seconds or every 30 feet of travel while within the ODMDS. In
addition to the continuous tracking data, the following trip information shall be electronically
recorded for each disposal event:
a. Load Number
b. Disposal Vessel Name and Type (e.g. scow)
c. Estimated volume of Load
d. Description of Material Disposed
e. Source of Dredged Material
f. Date, Time and Location at Initiation and Completion of Disposal Event
It is expected that disposal monitoring will be conducted utilizing the Dredge Quality
Management (DQM) system for Civil Works projects [see
http://dqm.usace.army.mil/Specifications/Index.aspx1. although other systems are acceptable.
Disposal monitoring and ETS data will be reported to EPA Region 4 within one week of disposal
utilizing the extensible Markup Language (XML) specification and protocol per Section 3.5.
More frequent reporting may be required on a project specific basis or if compliance issues arise.
EPA Region 4 and the USACE Jacksonville District shall be notified within 24 hours if disposal
occurs outside of the ODMDS or specified disposal zone or if any apparent leaking or spilling of
dredged material occurs as indicated by a loss of disposal vessel draft. The draft change
threshold for notification is 1.5 feet as outlined in Section 2.6 when east of the sea buoy and no
loss within the channel.
3.3 Post Disposal Monitoring
The USACE, or other site user, will conduct a bathymetric survey within 30 days after disposal
project completion. Surveys will not be required for projects less than 50,000 cubic yards.
Bathymetric surveys will be used to monitor the disposal zone to assist in verification of material
placement, to monitor bathymetry changes and trends, and to ensure that the site capacity is not
exceeded, i.e., the mound does not exceed the site boundaries. Surveys will conform to the
minimum performance standards for Corps of Engineers Hydrographic Surveys as described in
the USACE Engineering Manual, EMI 110-2-1003, Hydrographic Surveying dated November
30, 2013
rhttp://www.publications.usace.armv.mil/Portals/76/Publications/EngineerManuals/EM 1110-2-
1003.pdf] or appropriate update. The number and length of transects required will be sufficient to
encompass the release zone and a 500-foot wide area around it. Single beam surveys will be
taken along lines spaced at 200-foot intervals or less. Multibeam surveys will provide 100%

coverage. 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 Material Tracking and Disposal Effects Monitoring
Surveys can be used to address possible changes in bathymetric, sedimentological, chemical, and
biological aspects of the ODMDS and surrounding area as a result of the disposal of dredged
material at the site. A summary of available technologies is provided in USACE (1990).
Techniques anticipated to be utilized at the Port Everglades Harbor ODMDS include, but are not
limited to:
Multibeam Sonar: Mapping disposed dredged material; identifying hard bottom
Sidescan Sonar: Mapping disposed dredged material; identifying hard bottom
Sediment Profile Imaging: Mapping disposed dredged material; characterizing physical,
chemical and biological seafloor processes; evaluating benthic infaunal recolonization
through the mapping of infaunal successional stages
Planview Image Acquisition and Analysis: enumeration of biological features (biogenic
mounds, burrows, tracks, feeding pits/furrows and epifauna); enumeration of physical
sedimentary features (rocks, hard bottom, sand ripples), and apparent presence/absence of
dredged material
Benthic infauna sampling: document and quantify benthic infauna communities; identify
absence of any pollution sensitive organisms
Benthic chemical sampling: document changes in sediment chemistry and identify any
contaminant concentrations that may pose a threat to the environment or human health
Benthic grain size sampling: document changes in the grain size of the benthos that could
affect benthic populations
Water quality sampling: document any changes in the chemical and physical properties of
the water column that may adversely affect the marine environment or human health;
collect data for risk assessment models for evaluating the effects of dredged material
disposal
Remotely Operated Vehicle (ROV) underwater video/still image surveys to assess
surface and habitat type, species presence, and other elements related to the physical and
biological makeup of the ODMDS.
3.4.1 Summary of Results of Past Monitoring Surveys
Surveys conducted at the Port Everglades Harbor ODMDS are listed in Table 4. Two disposal
events have occurred since site designation. After the first event, no measurable change in
bathymetry was detectable. A post disposal benthic assessment using Sediment Profile Imaging
(SPI) showed that dredged material disposal formed an elliptical deposit on the seafloor within
U.S. EPA Region 4 / USACE Jacksonville District
Page 18

Port Everglades Harbor ODMDS SMMP May 2020
the northern portion and extending north of the original ODMDS. This resulted in a shift to a
slightly sandier substrate at the ODMDS. There was no indication of any adverse changes in
oxygen demand, redox state, or other geochemical properties as a result of disposal. Results
suggested that while benthic communities over the dredged material deposit were rapidly
approaching those on the ambient seafloor relatively soon after disposal, this process was still
ongoing at the time of the survey and not yet complete. Sampling conducted as part of the site
expansion survey in 2011 indicated that concentrations of metals, organic tins, PAHs, PCBs and
pesticides within the original ODMDS are above background levels. However, they remain
below Probable Effect Levels as well as levels found in the dredged material tested and accepted
for ocean disposal and therefore no adverse effects are expected.
As a result of the post-disposal SPI survey above, the release zone was modified. The 2013
maintenance dredging project utilized the new release zone. In 2014, a SPI and trend assessment
study was conducted. The SPI results demonstrated that the revised release zone was effective at
containing almost all of the material within the ODMDS boundaries. Only one station about 50
meters south of the ODMDS boundary was impacted by more than 5 cm of dredged material (6
cm). The main physical change in benthic habitats from dredged material disposal were a subtle
shift in sediment texture and redox state of surface sediments with grain size slightly coarse,
establishment of rubble areas within the ODMDS boundary, a higher proportion of fine shell
hash, and apparent shallowing of the apparent redox potential discontinuity (aRPD) layer depth
relative to native sediments. High levels of biogenic activity were found at the majority of
unconsolidated soft sediment stations, whether dredged material or native sediments. Except for
there being fewer feeding mounds at dredged material stations, there were no other patterns in
density and spatial distribution of biogenic features across the area. The sea star Coronaster
briareus was the only species to show a benthic habitat preference being almost twice as
abundant on unconsolidated soft sediment dredged material relative to native soft sediment and
dredged material hard carbonate bottoms. It appears that infaunal communities have successfully
recolonized the dredged material within 17 months of completion of the 2013 disposal event.
Macroinfauna sampling as part of the 2014 trend assessment study showed that annelids,
primarily polychaetes, comprised the majority of taxa assemblages, both inside (62.5%) and
outside (67.4%) of the Port Everglades ODMDS. The mean number of individual organisms and
taxa density was over 50% greater outside the ODMDS versus inside the ODMDS. The mean
number of taxa was also greater outside the ODMDS versus inside. However, due to the large
variability between stations, there was statistically no difference inside versus outside the Port
Everglades ODMDS regarding benthic assemblages. These changes are expected to return to
baseline condition over time and will be evaluated in future status and trend surveys.
3.4.2 Future Monitoring Surveys
Based on the type and volume of material disposed and impacts of concern, various monitoring
surveys can be used to examine if and which direction the disposed dredged material is moving,
and what environmental effect the material is having on the site and adjacent areas.
U.S. EPA Region 4 / USACE Jacksonville District
Page 19

Port Everglades Harbor ODMDS SMMP May 2020
It is expected that changes in sediment composition within the ODMDS due to disposed dredged
material will likely alter the benthic community structure somewhat. However, based on
previous benthic studies, it is unlikely that permanent or long-term adverse impacts will result
due to changes in sediment composition (see section 3.4.1).
A Trend Assessment and Baseline study is planned for 2020 to ascertain baseline conditions for
future trend analysis. Additionally, a SPI study will be conducted following the next major new
work project to evaluate the effectiveness of the new work release zone on maintaining material
within the ODMDS, if indicated.

The report should:
1)Indicate how the survey relates to the SMMP and previous surveys at the Port Everglades
Harbor ODMDS
2)Provide data interpretations, conclusions, and recommendations
3)Project the next phase of the SMMP and any management alterations required for future
site use
Monitoring results will be summarized in subsequent revisions to the SMMP.
4.0 MODIFICATION OF THE PORT EVERGLADES HARBOR ODMDS
SMMP
Should the results of monitoring surveys or reports from other sources indicate that continued
use of the ODMDS would lead to unacceptable effects as determined by EPA and USACE and
outlined in the 1991 Green Book, the SMMP will be modified to mitigate the adverse impacts
using appropriate management measures. 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 otherwise
indicate a need for revision.

accordance with COE EM 1110-1-2909. A copy of the EM can be downloaded from the
following web site: http://www.usace.army.mil/inet/usace-docs'eng-manuals/em.htm. Horizontal
location shall have an accuracy equal to or better than a standard DGPS system, equal to or better
than plus/minus 10 feet (horizontal repeatability). Vertical (draft) data shall have an accuracy of
plus/minus 0.5 foot. Horizontal location and vertical data shall be collected in sets and each data
set shall be referenced in real-time to date and local time (to nearest minute) and shall be
referenced to the same state plane coordinate system used for the survey(s) shown in the contract
plans. The ETS shall be calibrated, as required, in the presence of the Contracting Officer at the
work location before disposal operations have started, and at 30-day intervals while work is in
progress. The Contracting Officer shall have access to the ETS in order to observe its operation.
Disposal operations will not commence until the ETS to be used by the Contractor is certified by
the Contracting Officer to be operational and within acceptable accuracy. It is the Contractor's
responsibility to select a system that will operate properly at the work location. The complete
system shall be subject to the Contracting Officer's approval.
3.3.6.2 ETS Data Requirements and Submissions
a. The ETS for each disposal vessel shall be in operation for all dredging and disposal
activities and shall record the full round trip for each loading and disposal cycle. (NOTE:
-------
Port Everglades Harbor ODMDS SMMP May 2020
A dredging and disposal cycle constitutes the time from commencement of dredging to
complete discharge of the material.) The Contracting Officer shall be notified
immediately in the event of ETS failure and all dredging operations for the vessel shall
cease until the ETS is fully operational. Any delays resulting from ETS failure shall be at
the Contractor's expense.
b. Data shall be collected at least every 0.25 nautical mile or every 4 minutes during travel
to and from the ODMDS and 12 seconds or every 30 feet of travel while within the
ODMDS.
c. Plot Reporting (2 types):
a. Tracking Plot - For each disposal event, data collected while the disposal vessel is
in the vicinity of the disposal area shall be plotted in chart form, in 200-foot intervals, to
show the track and draft of the disposal vessel approaching and traversing the disposal
area. The plot shall identify the exact position at which the dump commenced.
b. Scatter Plot - Following completion of all disposal events, a single and separate
plot will be prepared to show the exact disposal locations of all dumps. Every plotted
location shall coincide with the beginning of the respective dump. Each dump shall be
labeled with the corresponding Trip Number and shall be at a small but readable scale.
c. Summary Table - A spreadsheet which contains all of the information in the
log(s) above shall be prepared and shall correspond to the exact dump locations
represented on the Scatter Plot.
d. ETS data and log data required by Section 3.3.4 shall be provided to EPA Region 4 on a
weekly or more frequent basis. Data shall be submitted to EPA Region 4 as an
extensible Markup Language (XML) document via Internet e-mail to

For scows, the monitoring profile, TDS profile or Ullage profile shall be used.
3.3.6.3 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. Re-dredging of such materials
will be required as a prerequisite to the resumption of dredging unless the Contracting Officer, at
his discretion, determines that re-dredging of such material is not practical. If re-dredging 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.
In addition, the Contractor must notify the Contracting Officer, US ACE and the Environmental
Protection Agency Region 4's Oceans and Estuary Management Section
(OceanDumpingR4@epa.gov) within 24 hours of a misplaced dump or any other violation of the
Site Management and Monitoring Plan for the Port Everglades Harbor ODMDS. Corrective
actions must be implemented by the next dump and the Contracting Officer must be informed of
actions taken.
