Introduction
Tipping Point Resources Group, LLC (“TPRG”) has prepared this Contingency Plan to support
activities related to the Connecticut Department of Energy and Environmental Protection (“CT
DEEP”) Solid Waste Demonstration Project Authorization received on January 5, 2022. Revisions
in this document include:
1.the addition of complementary stabilization mixing tools,
2.offloading alternatives on the North and South Piers,
3.improved onsite operational layout and
4.the addition of new key personnel with particular expertise and operational experience in
sediment management and processing.
Stabilization and dredged material processing with a preference of beneficial upland reuse will
be performed per the authorization and in accordance with additional CT DEEP guidance in
particularly with the deployment of additional technologies and enhancing flexibility and controls
on onsite operations.
The BlueTech Innovation Center affiliation and moniker will provide an enhanced opportunity to
consider and evaluate new and innovative technologies. By the addition of more classic
operations such as pugmill mixing, baseline operations at the site can compete as a hub for New
England’s first regional sediment management program providing a selection of alternative
beneficial re‐use options (at brownfields and other locals) for historically poor geotechnical
quality dredged materials. By combining proven and innovative technologies, experienced
personnel, and industry experts to improve the material with Portand cement (and other
binders), an improved quality engineered fill to address regional brownfield capping needs is
produced/manufactured for related construction opportunities.
Only stabilization tools shown in this document will be used. We do not currently have any plans
to add additional technologies. However, if from BlueTech’s efforts additional methods of
processing are suitable, we may propose to the State and Local authorities for an evaluation and
consideration via formal application or modification requests.
The vision of a BlueTech Innovation Center is to leverage Tipping Point’s innovation and technical
experience together with solid contracting expertise to catalyze the growth of multiple, maritime
dependent technology companies at the Montville/Uncasville, Connecticut location.
This Contingency Plan “describes corrective measures to be taken in the event of equipment
breakdowns, delivery of unacceptable materials, spills, fires, extreme weather or other events.”
It has been prepared to address the corrective measures that will need to be immediately
Tipping Point Resources Group, LLC Page 8 8
implemented and completed in case any events occur that may affect the operation of the
processing facility. This plan will be kept on‐site at the Thames River Facility processing site
(located at 125 Depot Road, Montville, CT) and updated as the project continues to ensure
adequate planning for potential events that could impact operations.
Marine Materials Management (M3) and BlueTech/TPRG will be operating with Gateway
Terminal, Inc. (“GT”) and will coordinate all responses to spills and/or releases with GT.
Tipping Point Resources Group, LLC Page 9 9
Process Background
The M3/TPRG sediment processing location in Montville, CT has the capability of processing up
to 2,500 cubic yards (yd3) of sediment per day, based upon processing rates specified in the Solid
Waste Demonstration Project Approval (SWDP Approval No. 08601340‐DP). There may be
periods of lower processing rates depending on project dredging operations and the dredging
contractor’s ability to provide material. During operations, M3/TPRG will coordinate all
movement of barges, scows, trucks, and equipment with GT personnel. This Contingency Plan
will be kept on site in the office trailer adjacent to TPRG processing operations. Address and
contact information for principal GT and TPRG personnel are provided in Table 1.

Sediment processing operations will be limited to a subsection of the 125 Depot Road, Montville,
CT property. Figures 1 and 2 detail this designated area and the proposed Thames River Site
layout.
This Contingency Plan has been prepared to address equipment issues, delivery of unacceptable
sediment for processing, environmental releases, extreme weather, and transportation delays. It
is limited in scope to contingencies for processing operations at the Thames River Facility.
In the case of unforeseen events occurring onsite that result in unsafe or suboptimal operating
conditions for the systems or personnel, operations will be halted and problem remedied in order
to continue operating in a safe manner.

Stabilization Technology & Equipment Breakdowns
Overview
Several mixing tools will be used onsite that may include a Pneumatic Flow Tube Mixing (PFTM)
system, a standard pugmill system, and AlluTM style mixing head attachments on standard
excavation equipment and in‐barge stabilization. Each of these techniques for stabilizing pre‐
screened (chemically and geotechnically) sediments can be used to produce engineered fill
products for use in offsite construction. The amended dredged material sets up as a granulated
stiff clay that can be re‐worked with earth moving equipment within 24 hours of placement. It
does not set up as a concrete monolith.
Figure 3 provides a simplified system process flow diagram that can be used to identify individual
equipment and the corrective actions required to safely restore system operations.
Figure 3. S/S Process Flow Diagram
Tipping Point Resources Group, LLC Page 14 14
As shown in Figure 2, the general processes are:
Item B, Prepare for Offloading, is a step that will help manage water in incoming barges so that
materials transferred from the barge to the land are performed in the most efficient manner.
Excess water will be pumped to an onsite frac tank for recycling in the Portland cement batch
plant operations. Dry pneumatically delivered Portland cement will be accessible to the dock
for in‐barge mixing to stiffen the barges should conveyors be used to transfer materials.
Item C, Offloading will be at the discretion of the operators based on the material consistency,
the desired processing scheme considering incoming material characteristics and outgoing
requirements. There are three options incorporated into the plans as shown above.
For each project, a mobile spill containment berm and splash guard will be deployed in the
areas of material transfer on the dock. Dryer materials will likely be processed using the Allu
mixing heads or pugmill. Wetter materials will likely be processed using the PFTM, or
equivalent technology. The PFTM process was designed to be a reliable and resilient processing
system, as a result of fewer moving parts and a smaller overall process footprint. However,
equipment failure is still possible due to the nature of processing wet sediments with a Portland
cement slurry, especially at high processing rates.
All personnel will be trained on the safe and proper use of equipment. Only experienced and
trained personnel already familiar with the processing will operate and maintain the processing
equipment.
Equipment inspections, incident reports, and corrective actions will be documented via field
notes and the forms provided as Attachments to this Contingency Plan.
Tipping Point Resources Group, LLC Page 15 15
1.Vibratory Grizzly Screener
The “Grizzly” is a vibratory shaker screen, driven by electric motors, that screens out
oversized debris from the received dredged material. It is the “front‐end” of the M3/TPRG
processing operations. Sediment that passes through the screen is collected in a surge
tank/hopper directly beneath the Grizzly to be pumped through a sediment slurry process
such as the PFTM technology. The screened‐out debris is directed to roll‐off dumpsters,
where it can be segregated and disposed of appropriately (according to waste
characterization).
The Grizzly (or similar smaller‐capacity screening system) is an essential part of front‐end
material handling operations for a slurry and pugmill processes. As a result, redundant
system components (including extra motors and plates) will be stored onsite and local
contractors will be identified for immediate part replacement capabilities, in case of an
equipment failure. While a breakdown would cause delays in material processing and project
scheduling, there is no danger of a dredged material release if the Grizzly breaks down.
In the case of Grizzly/vibratory screen failure, dredged material loading activities will cease
and the equipment will be safely assessed to determine the cause of failure. Any close‐up
inspections or mechanical replacements/repairs will take place only once power has been cut
off from the equipment. Operations will not resume until all personnel are at a safe operating
distance from the moving equipment parts and the identified cause of failure has been fully
addressed.
2.Sediment Pumps
The sediment pumps are positive displacement electric pumps that are designed to pump
relatively high‐viscosity fluids or fluid mixtures (slurries) ‐ in this case, sediment. The sediment
pumps transport sediment from the hopper located beneath the Grizzly screener into the
PFTM or other slurry/in‐line processing pipeline. Critical pump replacement parts will be kept
on‐hand, to be installed in case of pump breakdown.
In the case of sediment pump failure, loading of the Grizzly/vibratory screener will cease to
avoid overfilling the sediment hopper. The pump will be safely assessed to determine the
cause of the failure. Any close‐up inspections or mechanical replacements/repairs will take
place only once power has been cut off from the sediment pump. Loading operations will not
resume until the sediment pump has been repaired or replaced and is fully operational again.
Tipping Point Resources Group, LLC Page 16 16
3.Computer System and Associated Sensors
Computer systems and sensor “feedback loop” are some of the most important elements
that make sediment slurry process flows efficient and sophisticated, compared to other
sediment processing methods. In the case of a computer system or sensor failure, operations
must automatically cease for the entire system. This may result in processing delays but will
not cause a release of any sort.
The computer system will be operated and maintained in a temperature‐controlled
environment (work trailer) and kept safe from security‐ or weather‐related issues. The
computer system and associated sensors will undergo routine calibration and performance
checks, and knowledgeable personnel (technical experts) will be onsite or available remotely
to troubleshoot performance issues or breakdowns. If access must be provided to sensors
housed within the processing equipment, operations will cease, and the system will be de‐
energized prior to any close‐up inspection or sensor handling for repair. System operations
will not resume until the computer system and sensors have been restored in a safe and
effective manner.
4.Cement Plant
A cement silo and batch plant are used to prepare the Portland cement slurry that is injected
into PFTM processing equipment or for dry powder addition for allu mixing/pugmill for
sediment stabilization. They are standard modular plant and can be replaced and/or swapped
out quickly, as necessary. Similarly, cement silos are used to store and supply cement powder
onsite and are considered standard equipment.
Potential leakage will be monitored and ascertained visually by onsite personnel, as well as
by computer operations “accounting” for raw material volumes. Once identified, any cement
raw product will be contained, cleaned up, and disposed of properly.
5.PFTM Mixing Tool and Pipes
The PFTM mixing tool is a patented, modified steel pipe that is extremely durable and not
expected to experience significant wear. The pipes within which the sediment plugs are
transported are primarily steel pipes that can be separated into isolated sections for cleanout
in the event of a clog. HDPE piping may also be used. Based on the experience of PFTM
operations in Japan, it is anticipated that these pipes have very low failure rates. Typically,
these steel pipes are replaced once per year under long‐term continuous use operations.
HDPE will be monitored for excessive ware and changed accordingly.
Tipping Point Resources Group, LLC Page 17 17
Small sections of the processing pipeline may be constructed of corrugated vacuum hose,
rather than steel pipe, to allow flexibility. Additional hose will be kept onsite to replace any
sections that may become compromised due to wear and use over time.
6.Ancillary Equipment
Additional standard pieces of equipment, such as air compressors and generators, will be
required to supply power and materials to the PFTM and Pugmill systems. These pieces of
equipment will be maintained according to the manufacturer’s recommended maintenance
schedule, and records of maintenance and inspections will be kept onsite as part of the
permanent equipment record for facility operations. This equipment is standard and widely
available for rent. In the event of failure, replacement rental unit(s) will be delivered, and the
broken‐down unit(s) will be transported offsite for repair.
Based on its extensive use in Japan over the last two decades as well as the 2015 New
York/New Jersey Harbor commercial pilot demonstration, the PFTM system has been
demonstrated to be reliable and rugged with very few incidents of equipment breakdown.
Daily processing reports will also be prepared and kept onsite as part of the facility’s
operating record. These reports will include daily tailgate/safety briefings to discuss planned
operations as well as safety and contingency improvements (i.e. “Lessons Learned”).
Other Stabilization Technologies
In alignment with recent allowances to the Griswold, Connecticut site BUD and other upland
placement sites (eg., landfill caps), additional stabilization mixing tools and techniques will be
used at the site. The equipment comprising these technologies will be integrated onsite to meet
project, market and mixing needs. For emphasis, only material with testing meeting State, Local,
and Federally criteria at approved sites will be handled. This will be determined and documented
prior to acceptance at the site.
Delivery of Unacceptable Materials
For any project to be considered and contracted for sediment processing, we must first be
provided documentation of the dredged material characteristics. The results of sediment
characterization sampling will be evaluated and compared to the upland placement criteria
defined by the end‐use site’s Beneficial Use Determination (e.g, Griswold Triangle Wire Site) or
applicable solid waste regulatory criteria (e.g., landfill).
Tipping Point Resources Group, LLC Page 18 18
Any project material that is reasonably expected to not be in compliance with project end use
criteria will be managed as follows. An alternative disposal location, as appropriate based on the
material characteristics, will be identified for unacceptable project dredged material during the
project’s planning phase, so that material can be transported to an appropriate upland location
or facility minimizing delays.
In terms of physical material properties, it is possible that sediment may be delivered to the site
with an unacceptably high water content, a direct result of typical dredging operations. We will
work closely and directly with project dredging contractors to identify and enforce the acceptable
limits to sediment water content. While the systems can adjust Portland cement dosages in real‐
time to effectively stabilize sediment with a range of water contents, it would be wasteful and
inefficient to attempt to process material that contains significantly more water than solids.
Ultimately, we will either reject sediment deliveries that contain too much water or require that
the dredging contractor decants the excess liquid prior to receiving the sediment. We may collect
the excess water on the barges for use in the cement batch plant operations, thereby recycling
the water without the need for discharge or disposal. We will work directly and communicate
with the dredging contractor(s) to minimize high water content scows.
Tipping Point Resources Group, LLC Page 19 19
Releases/Spills
Very few potential releases could result from processing activities at the Site. These would
include:
1)Release of fuel used to power the generators, air compressor fluids and loader;
2)Release of sediment, either by human error in loading operations or by a breach in the
PFTM system or Pugmill, or Allu Mixing Systems; and
3)Release of Portland cement slurry due to a breach in the batch plant or delivery lines.
Site personnel and subcontractors involved in the work will be required to complete Health &
Safety and spill prevention/contingency training prior to site work.
Incident reports and corrective actions for any release events will be documented via the forms
provided as Attachments to this Contingency Plan. Once completed, digital copies of the forms
will be submitted to TPRG management, and the original hard copies will be kept onsite as part
of the facility records.
1. Fuel Spills
The primary route for potential diesel fuel spills will be during fueling operations for heavy
equipment, such as the material loader, generators, and air compressors. Refueling will occur
upland, at a safe distance from the water, and will be completed during breaks in active
processing operations. Active spill response equipment, including absorbent materials, will
be stocked and available onsite. Standard procedures for fueling operations will also include
the inspection of valves to identify any leakage or improper connections both a) prior to
initiating fuel transfer, and b) during fuel transfer operations.
Once the refueling is completed, a final inspection will be conducted to ensure that there are
no loose connections, and the immediate areas will be inspected for the presence of fuel
and/or oil. In the event of an observed leak or spill, site personnel will use absorbent materials
and shovel/sweep up and dispose of the material properly while wearing proper PPE
(identified in a site‐specific Health and Safety Plan).
In the event of a large release, Site personnel will notify and follow GT’s spill response
procedure. Affected site operations will cease immediately, and the appropriate agencies and
emergency contacts will be notified.
Tipping Point Resources Group, LLC Page 20 20
2.Dredged Material Release
Material will be offloaded and conveyed to lined consolidation bins on the waterfront in front
of the South and/or North Piers. Spill Guards and secondary containment will be placed in
areas of material transfer from the barge to either the conveyor system or trucks. Materials
handling from the secured bins may include S/S via PFTM, Pugmill or mixing head operations.
For the PFTM system, prescreening using a Grizzly screener is the first, often throughput‐
limiting, step in the PFTM materials handling process. As a result, highly trained or expert
machine operators will be assigned to this role. Loading operators will be trained on the
expectations for safe and careful loading of dredged material into the Grizzly screener. Due
to the wet nature of the sediment, splash guards and/or secondary containment will also be
installed around the material transfer area to prevent possible releases.
In the event of sediment release, whether by human/operator error or splashing beyond
secondary containment, site personnel will shovel/sweep up the material while wearing
proper PPE (identified in a site‐specific Health and Safety Plan) and dispose of it properly ‐
most likely back into the scow or containment bin with the remaining unprocessed dredged
material.
A far less likely scenario for potential sediment release would be the rupture or breach of the
PFTM system processing pipeline. The processing pipeline consists of approximately 300 feet
of steel pipes and up to 50 feet of corrugated vacuum hose, with sections securely attached
to each other. Pipeline assembly and operation will occur on land. Any leakage or releases
from the system will be addressed as stated above.
Front‐end pre‐screening for oversized materials is less important for standard pugmill and
mixing head applications.
3.Cement Slurry Release
Cement slurry is often used as the stabilizing agent for the sediment treatment process.
Portland cement can be mixed with water in the cement batch plan to form a slurry, which is
pumped via a grout pump to the PFTM mixing tool for injection into the pipeline. The slurry
will be transported via a pressurized line that is securely connected via industry standard
connectors. Controlled addition of dry PC based mixes is achievable with Standard Pugmill
and mixing head processes.
The only potential scenarios for slurry release would be from connection failure or a ruptured
line (due to wear or accidental impact). The cement slurry equipment will be inspected
regularly, and observations will be documented within field records. Equipment that is
Tipping Point Resources Group, LLC Page 21 21
observed to be worn or potentially broken will be fixed and/or replaced with urgency.
Additional administrative controls will protect the grout line from accidental impact, such as
markers identifying the location of the line and/or implementation of an exclusion zone to
restrict close contact with mechanical activities. It is anticipated that this zone would also
include the PFTM processing lines and sensor cables.
Extreme Weather
Due to the nature of the work facility operations will likely endure temperature fluctuations
(freezing), various forms of precipitation (including nor’easters and winter storms with
precipitation), as well as high winds and severe weather events. The systems are extremely
rugged and have been designed for stability through inclement weather.
While the equipment is weather‐resistant, site personnel and support activities such as material
loading and transportation will be susceptible to the weather. Facility operations will only occur
when it is deemed safe. The types of extreme weather that would impact our ability to process
sediment safely would also preclude dredging, and therefore eliminate the possibility of
sediments being delivered (and accumulating) onsite during processing down‐time.
The most likely challenging weather to be experienced at the site is extreme cold which is subject
to icing. As mentioned, the conventional dredging window for Connecticut would limit much of
the processing season to occur during winter months. During periods of extreme cold, water and
slurry lines and reservoirs will be heated using heat trace or an equivalent product to protect
against freezing. Site personnel will also be required to wear proper PPE for winter operations.
Since the system is computer‐automated and controls will be located within the onsite office
trailer, operating personnel should face limited exposure. Heated worksite trailers and other
administrative controls for cold weather protection will be made available to keep personnel safe
from exposure.
Tipping Point Resources Group, LLC Page 22 22
Transportation Delays
Material transportation and handling is vital to dredged material processing operations at the
processing site. Individual project scenarios will dictate the method for dredged material
transport to the site, but it is expected that the majority of dredged material will be transported
via scow to the site’s waterfront bulkhead. The dredged material will be unloaded into an upland
containment area (created using concrete barriers and appropriate liners, or equivalent) to limit
waterside activities. Based upon the processing rates specified in the Solid Waste Demonstration
Project Approval (SWDP Approval No. 08601340‐DP), up to 5,000 yd3 of unprocessed dredged
material may be staged in this upland containment area at a given time.
Dredged material will be loaded from the containment area after mixed with PC (mixing head),
mixed with PC as loaded into a pugmill, or into the vibratory Grizzly screener and processed via
the PFTM processing system. The stabilized material will be discharge via the PFTM diffuser or
directly from the pugmill into designated “curing” containment bins to begin strengthening and
drying out prior to transloading. Once the stabilized sediment has become “workable”
(approximately 12‐24 hours after discharging), the material will be loaded onto individual tri‐axel
trucks for transport to the permitted placement site (such as the Griswold Triangle Wire
Brownfield site). It should be noted that upon truck transport, the amended dredged material
will have the characteristics of an engineered fill (not liquid) and that no splashing or spillage will
occur.
A delay in any of the above steps would have a significant impact upon our ability to reach the
processing goal of up to 2,500 yd3 per day. We expect to maintain enough capacity in the
containment areas for both a) unprocessed dredged material, and b) stabilized dredged material,
to absorb one to two days’ delay or downtime. In order to preserve site capacity, it is paramount
that material is moved on‐ and offsite on a daily basis. We will maintain open lines of
communication with both dredging and trucking operations to identify and circumvent
misalignment as quickly as possible. At least one day’s notice is expected to confirm truck
transportation schedules.
