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 Jacksonville ODMDS in June 1997. This revision to the
Jacksonville ODMDS SMMP supersedes the 1997 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 1997 Jacksonville ODMDS SMMP. The team
consisted of the following agencies and their respective representatives:
• Jacksonville District Corps of Engineers
• State of Florida (Coastal Zone Management Office)
• EPA Region 4
• U.S. Navy (Naval Station Mayport)
• Port of Jacksonville
• National Marine Fisheries Service (NMFS)
• U.S. Coast Guard
These agencies will continue to be consulted in revisions to the Jacksonville 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:
EPA: EPA is responsible for designating/dedesignating MPRSA Section 102 Ocean
Dredged Material Disposal Sites, for evaluating environmental effects of disposal
dredged material at these sites and for reviewing and concurring on dredged material
suitability determinations.
-------
November 2007
Jacksonville ODMDS SMMP
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 Jacksonville ODMDS can be found in 40 CFR 228.15(h)(9). The
Jacksonville ODMDS is a 1 nautical mile (nmi) by 1 nmi square area centered at the coordinates
30° 21.00'N latitude and 81 ° 18.00'W longitude (NAD 27) or state plane coordinates 2,187,428.7
ft N and 561,602.6 ft E (NAD83). The site coordinates are as follows:

The site is 4.5 nmi offshore with an area of 1 nmi2. As of 2007, it had a depth range of 10 tol8
meters (32 to 60 feet), with an average depth of 14 meters (46 feet).
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 Jacksonville 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
Jacksonville, 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 Jacksonville ODMDS and vicinity
has been used for the ocean disposal of dredged material since 1952. Material disposed prior to
1970 and in the early 1970's was disposed in an area 0.5 nautical miles east of the Jacksonville
ODMDS. In the late 1970's material was disposed south of the site. Table 1 outlines the history
of disposal of material.

Since 1995, Naval Station Mayport has utilized the Jacksonville ODMDS on a biannual basis for
the disposal of maintenance material. This material typically consists of silts, soft clays and sand
mixtures. The Jacksonville Harbor Federal Navigation Project has used the site for disposal of
coarse material not suitable for beach placement from the entrance channel. It is expected that
the Naval Station Mayport will continue to utilize the ODMDS at existing levels and the
Jacksonville Harbor Federal Navigation Project will also continue to utilize the ODMDS for
non-beach compatible material in the entrance channel. As upland disposal alternatives become
limited the volumes from the Jacksonville Harbor Federal Navigation Project may increase and
USACE-Jacksonville District U.S. EPA Region 4

additional permitted projects may identify a need for ocean disposal. In addition, the U.S. Fleet
Force Command (Navy) has begun the process of preparing an Environmental Impact Statement
(EIS) for the proposed Homeporting of Additional Surface Ships at Naval Station Mayport.
Some alternatives could include the generation of up to 5.7 million cubic yards of dredged
material. It is expected that the Jacksonville ODMDS will be considered an alternative for some
or all of the material.
The capacity of the Jacksonville ODMDS has yet to be determined. A capacity study has been
initiated by EPA Region 4 and the USACE (see Section 3.5). Until the study is completed, use
of the ODMDS will continue to be temporarily restricted to 2 million cubic yards per year as
established in the 1997 SMMP. This restriction is based on maximum historical uses of the
ODMDS. Upon completion of the capacity study, the study results will be provided to the
SMMP team members for review prior to modification of the site volume limits.
Priority for ODMDS use within the capacity constraints will be given to maintenance projects
from the Naval Station Mayport and the Jacksonville Harbor Federal Navigation Project.
Approval for new work projects or maintenance material from non-federal projects will be
dependent on a consideration of site capacity and long-term (ie.10 years) maintenance needs
from the aforementioned maintenance projects.
2.4 Dredged Material Characteristics. The composition of dredged material dumped at the
Jacksonville ODMDS has been extremely variable. The majority of the dredged material
destined for disposal in the ODMDS is expected to be composed of silt (10 percent to 60
percent) and clay (10 percent to 30 percent). Disposal of gravel and rock has occurred in
association with the Jacksonville Harbor Deepening Project, completed in 1977. Coarse material
such as shell hash from the entrance channel not suitable for beneficial use has also been
disposed in the ODMDS. Sediments dredged to maintain the Entrance Channel and certain
reaches of the St. Johns River downstream from Jacksonville are predominantly fine- to medium-
grained sands and are consequently typically used for beach renourishment projects and not
disposed in the Jacksonville ODMDS. Sediments from Mayport Harbor are predominantly silts
and clays.
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 State of
Florida will exercise its 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
rubble, should be coordinated with the State of Florida and EPA to avoid unintended impacts in

the ODMDS and 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 bioassay (toxicity and
bioaccumulation) testing 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/USACE Dredged Material Testing Manual and 1993
Regional Implementation Manual (RIM) or the appropriate updated versions. 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 RIM. Water
Quality Compliance determinations will be made using the STFATE (ADDAMS) model and the
input parameters provided in Appendix A. The U.S. Navy, EPA Region 4, the State of Florida,
and the USACE developed an agreement (EPA XL/ Department of Defense ENNVEST) for the
testing and permitting of maintenance dredged material from Naval Station Mayport for ocean
disposal at the Jacksonville ODMDS. This agreement available at
http://www.epa.gov/proictxl/mavport/index.htm incorporates the requirements described above
but outlines specific timelines for permits and testing strategies. Only material determined to be
suitable through the verification process by the USACE and EPA, Region 4 will be placed at the
Jacksonville 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 sea turtle restrictions. As monitoring results are compiled,
should any such restrictions appear necessary, disposal activities will be scheduled so as to avoid
adverse impacts. During the winter, precautions necessary to protect whales, as described in the
next paragraph, are required. Additionally, if new information indicates that endangered or
threatened species are being adversely impacted, restrictions may be incurred.
2.6 Disposal Technique. No specific disposal technique is required for this site. However, in
order to protect North Atlantic right whales, 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. Based on the results of the bathymetry surveys, the disposal zone radius
can be increased from 1,500 feet specified in the 1997 SMMP to 2,000 feet. The surveys to date
have indicated that this size zone is adequate for maintaining the disposal mound within the
ODMDS boundaries (see Section 3.4). For operational reasons, the zone has been changed from
a circle to a rectangle. The disposal zone coordinates are as follows:

Disposal should be initiated within the disposal zone. Project specific release zones can be
defined within this disposal zone in order to better distribute dredged material throughout the
ODMDS and to avoid shallow areas within the ODMDS.
2.8 Permit and Contract Conditions. The disposal monitoring and post-disposal monitoring
requirements described under Site Monitoring 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 2. Template language
that can be used is included in appendices (see Appendix B and C).

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 Jacksonville
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 datasharing, 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.

3.1 Baseline Monitoring. Disposal has occurred at the present site since 1952. Therefore, no
true baseline information has been or can be collected. The results of investigations presented in
the designation EIS and subsequent surveys listed in Table 3 will serve as the main body of data
for the monitoring of the impacts associated with the use of the Jacksonville ODMDS.
A bathymetric survey will be conducted by the USACE or site user within three (3) months prior
to dredging cycle or project disposal. 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, ie., the mound does not exceed the site boundaries. 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 rhttp://www.usace.army.mil/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 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). No additional pre-disposal monitoring at this site is required.

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 weekly basis utilizing the extensible Markup
Language (XML) specification and protocol per Section 3.6. 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. As a follow-up to the pre-disposal bathymetric survey, the
USACE or other site user will conduct a bathymetric survey within 60 days after disposal project
completion. The number of transects required will be the same as in the pre-disposal survey.
Bathymetric survey results will be used to insure that unacceptable mounding is not occurring
and to aid in environmental effects monitoring.
3.4 Summary of Results of Past Monitoring Surveys. Surveys conducted at the Jacksonville
ODMDS are listed in Table 3. Monitoring activities during the 1970's indicated significant
mounding occurring at the site and that a small amount of dredged material had been transported
to the south, as demonstrated by bathymetric, physical, and chemical analyses of sediments.
Since re-initiation of disposal activities at the ODMDS, mounding has increased (see figure 2).
These bathymetric trends indicate that the site is not dispersive and a significant amount of
disposed material remains on site. Both thel978 study of the site and the 1995 and 1998
sediment mapping surveys indicated the presence of fine grained dredged material south of the
site boundaries. Predominant currents in the area flow southwest in the fall and winter and

northeast during spring and summer. Larger waves in the area are predominantly from the east
and occur in the winter. It is possible that some southerly transport of dredged material occurs in
the fall and winter due to wave induced resuspension.
Sediment analysis in the late 1970's showed higher concentrations of certain heavy metals (Ni,
Cu, Zu, Pb, and Cr), Kjeldahl nitrogen and organic carbon in sediments within the disposal site
versus outside the site. This is to be expected as material high in metal concentrations, requiring
a waiver of EPA's criteria was disposed at the ODMDS. Sediment analysis as part of the 1995
benthic survey showed that in general metal concentrations within the ODMDS remain elevated
compared to outside of the ODMDS. However, concentrations within the ODMDS have
decreased since 1978 and based on the 1998 study continue to decrease. The average percentage
of silts and clays at stations within the ODMDS exceeds that of stations outside the ODMDS, but
has decreased both inside and outside of the ODMDS since 1978. Figure 3 shows that metal
concentrations within the site have increased following significant ODMDS use in 1972 and
1978 followed by decreases.
A benthic infaunal survey was conducted in 1986. Results of the macro infaunal community
analysis indicated no difference between disposal and control stations and no difference could be
found which could be related to active disposal. A second benthic infaunal survey was
conducted in 1995. The sampling stations were composed primarily of sand, with silt/clay
content of less than 10%. Station 4, in the center of the disposal pile, had the highest silt/clay
fraction, and interestingly also had the highest gravel fraction (@21 %). Comparisons of the
stations' mean densities and mean number of taxa showed that the only significant differences
observed are more likely to be related to the grain size distribution differences seen and not
related to the presence or absence of disposed dredged material. Benthic community indices
showed that all stations were extremely diverse with an equitable distribution of taxa when
compared to known infaunal assemblages from the same general coastal region. Numerical
classification of the 12 stations tended to group the stations relative to the coarser grain size
fractions. The 1998 study showed that communities remain diverse and no significant changes
were observed either temporally or spatially.

A sidescan survey was conducted in March, 1995. Results of the survey showed the site and the
area north of the site to be cluttered with various types of debris and artificial reef material. This
is consistent with historical uses of the area. Although not designated as such, this site has
historically been used as a disposal location in rough weather for artificial reef material destined
for artificial reefs further offshore. Subsequent reconnaissance by divers identified biological
resources near the center of the site. Based on visual observations these resources are associated
with past disposal of construction material. A video survey was attempted at the site, but due to
poor water clarity no data was collected.

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.
At the current time, no nearby resources have been identified that are of concern for potential
impact. Near shore shrimping grounds are located between the site and the coastline and both
natural and artificial reefs are common on the mid-shelf east of the site. Monitoring results
indicate that the disposal mound is relatively stable with possible southerly transport of material
so that these areas should not be of concern. Sediment composition within the site may be
altered as a result of disposal of clay and silty material on otherwise sandy sediments.
Progressive transition to sediments containing a higher percentage of silt and clay is inevitable
with continued use of the site. Changes in sediment composition will likely alter the benthic
community structure. However, based on previous benthic studies, it is unlikely that permanent
or long-term adverse impacts will result due to changes in sediment composition.
A summary of the monitoring strategies for the Jacksonville ODMDS and thresholds for
management actions are presented in Table 4. Currently, the major concern at the Jacksonville
ODMDS is capacity. Data collection (waves, currents, dredged material erosive properties) for
modeling site capacity has already begun and is scheduled to be completed by the end of 2007.
Current data will also be used for development of standard water quality model input parameters.
Should future disposal at the Jacksonville 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 be 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 Jacksonville 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 JACKSONVILLE 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.

(1) 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. A sample Track and Draft
Plot Diagram is on the web site indicated in paragraph CONSTRUCTION
FORMS AND DETAILS below.
(2) 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. A sample Scatter Plot
Diagram is on the web site indicated in paragraph CONSTRUCTION
FORMS AND DETAILS below.
(3) Summary Table - A spreadsheet which contains all of the information in the

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 NonPoint Source 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 Jacksonville ODMDS.
Corrective actions must be implemented by the next dump and the Contracting Officer
must be informed of actions taken.
