Approximately 12.5 million tons of cargo is shipped annually in the Cleveland Harbor. To maintain this federal navigation channel, an average of approximately 300,000 cubic yards of sediment is dredged every year. Dredged sediments from the Cuyahoga River do not meet Ohio EPA standards for open lake placement. Existing confined disposal facilities (CDFs) are near design capacity and the cost and challenges to locate, design and construct new CDFs cannot be completed under current U.S. ACE budgets. Also, this work could not be accomplished before the existing CDF capacity is exhausted. The Port Authority is completing a sustainable sediment management study to identify and evaluate both near and long-term solutions to address this crisis. Presenters will share research findings and study results regarding the expanded use of existing CDFs through increased capacity, beneficial use for upland site restoration, and creation of beneficial use products, among others. This “Science of the Great Lakes” session will also include planned steps for implementation of study recommendations.

Global Status of CCS: 2016. Saline Aquifer Storage Performance at the Quest C...Global CCS Institute
The Global CCS Institute launched The Global Status of CCS: 2016 at a dedicated event at the 22nd conference of the parties (COP 22) in Marrakech on Tuesday, 15 November.
The Global Status of CCS: 2016 report is an essential reference for industry, government, research bodies, and the broader community, providing a comprehensive overview of global and regional CCS developments.
Following the report launch, we will run a number of webinars commencing in November 2016, through to early 2017.
A Summary of the Global Status of CCS: 2016 will be accessible on our website from 15 November, and includes updates on key CCS facilities, including two major facilities now in operation:
Shell’s Quest Project in Canada
Tomakomai CCS Demonstration Project in Japan
These projects are significant 2016 milestones and testament to the safety, reliability and cost-effectiveness of CCS as an integral technology to meeting Paris Agreement climate change targets.
Please join us for the first of the Global Status of CCS: 2016 webinar series.
Saline Aquifer Storage Performance at the Quest CCS Project
As one of a handful of large-scale CCS projects currently injecting CO2 into a dedicated saline aquifer storage site, Shell’s Quest project offers a unique case study into the performance of dedicated storage. The Quest project injects CO2 into the Basal Cambrian Sandstone located 2 km below the surface. After the first year of operations, the Quest reservoir has exceeded internal expectations. While the original premise called for eight wells, today only two of three constructed injection wells take 100 per cent of project volumes (~140 tonnes /hr).
In this webinar, Simon O’Brien, Shell Quest Subsurface Manager, discussed storage performance at Quest after one year of operations as well as early results from the measurement, monitoring, and verification (MMV) plan.
CarbonNet storage site characterisation and selection processGlobal CCS Institute
The CarbonNet Project has undertaken an extensive geoscience evaluation programme to identify, characterise and select prospective offshore storage sites in the nearshore Gippsland Basin, in south eastern Australia.
The process builds upon basin and regional assessments undertaken at the national level, and focuses upon leads and play fairs assessed using a vast amount of geological data available from 50 years of petroleum exploration and developments in the basin.
CarbonNet geoscience work has been subject to independent scientific peer reviews, and external assurance certification by Det Norske Veritas against the recommended practise for geological storage of carbon dioxide (CO2) J203.
CarbonNet now holds five greenhouse gas assessments permits providing exclusive rights to explore, appraisal and develop a portfolio of CO2 storage sites.
The project has identified a prioritised storage site capable of storing in excess of 125 Mt of CO2 for which a 'Declaration of Storage' has been prepared which demonstrates the 'fundamental determinants' and probability assessment of potential CO2 plume paths as required under Australian CCS legislation'.
This webinar will be presented by Dr Nick Hoffman, CarbonNet Geosequestration Advisor, and will provide an overview of CarbonNet geoscience evaluation programme, referencing the relevant knowledge share products available on the Global CCS Institute website.

In a May 9, 2024 paper, Juri Opitz from the University of Zurich, along with Shira Wein and Nathan Schneider form Georgetown University, discussed the importance of linguistic expertise in natural language processing (NLP) in an era dominated by large language models (LLMs).
The authors explained that while machine translation (MT) previously relied heavily on linguists, the landscape has shifted. “Linguistics is no longer front and center in the way we build NLP systems,” they said. With the emergence of LLMs, which can generate fluent text without the need for specialized modules to handle grammar or semantic coherence, the need for linguistic expertise in NLP is being questioned.

Editor's Notes
Jenny – introduce speakers at one time
Created in 1968 and includes 125 acres of waterfront property Averages 10 million – 15 million tons of domestic and international trade annually Average of approximately 230,000 cubic yards of sediment is dredged every year from the federal channel Material does not meet standards for open-lake placement Currently placed into confined disposal facilities (CDFs) CDFs are nearing capacity and are very costly and timely to permit/construct Cleveland Harbor is 5 th busiest port on Great Lakes Cleveland Harbor is identified as a “Critical” Dredged Material Management Status - access to the shipping channel could be restricted within 5 years Several industries along river depend on navigable waters of the Cuyahoga to move goods Assurance of navigable waters also helps in promotion of real estate to future users The Ship Channel depth of 23 feet acts as a settling basin for sediments (sand, soil, and gravel). Each year, 200,000 to 250,000 cubic yards of sediment is dredged from the channel. Currently, because of latent toxicity which is above levels that would allow open lake placement, the dredged materials are placed in Confined Disposal Facilities (CDFs), developed and managed by the US Army Corps of Engineers (COE). Local CDFs are nearing capacity and very costly (local cost share for a new CDF could be $100 million). New alternative methods for dealing with sediment need to be developed. Jim – how much is dredged from the non-federal channel?

The Cuyahoga Ship Channel- (the lower 5.5 miles of the Cuyahoga River) is a critical tool of the regional economy, providing access for maritime commerce which supports 17,000 jobs in the NE Ohio.
The Port Authority has stepped up to the plate to lead an effort to reduce the amount of sediment entering the harbor and evaluate opportunities for the beneficial use of dredged material. The Port of Cleveland's Strategic Action Plan policies calls on the Port to step up in unprecedented ways to deliver on community ambitions for job creation, economic vitality, and waterfront renewal. The Plan is organized around three key themes, seven recommendations, and a set of implementing actions: explain. As part of recommendation 3, there are several action items that the Port is seeking to implement. Recommendation 3 of the Port Authority’s newly adopted Strategic Plan includes Leading Critical Initiatives for River Renewal and Infrastructure Improvements. This recommendation includes action items for the Port to Lead Development of a Sustainable Sediment Management Program that Focuses on Beneficial Use and to Aggressively Pursue Interagency Agreements and Funding Opportunities to Implement the Program This initiative is based on the premise that all of the dredged sediment is not a waste product, but rather a significant portion may be a resource that can be used to benefit the community and used for a variety of markets and uses. In order to pursue implementing this initiative, the Port is undertaking a variety of activities, which will be the focus of today’s session.
The Port has taken the lead on developing a sustainable sediment management strategy which includes employing BMPs, which intercept the sediment prior to reaching the open lake. While there are a variety of BMPs, today I will discuss bed load interception. In addition to BMPs, optimizing the CDF and beneficially using some or all of the dredged material for beneficial use projects such as brownfields and development, and potential unrestricted open-lake placement. In order to develop these elements, the Port is working with representatives from Hull & Associates and Moffatt and Nichol, Inc., who are assisting with developing and implementing portions of this strategy, including a hydrodynamic and sediment characterization approach. The Port is also working with Streamside Systems and the University of Akron to complete a bed load interception study, which is investigating the feasibility of intercepting some of the sediment before it reaches the navigation channel.
Sediment moves downstream in a river system in suspended and dissolved form. Dissolved and suspended are small particles that do not easily settle out. Suspended sediments , consisting of very fine particles and organics, move mostly during higher river discharge periods. Bed load sediment is comprised of heavier, larger grain sized material and bounce and tumble along the bottom. Bed load sediments move constantly in all flow conditions. As part of its strategic leadership for sediment management, the Port of Cleveland has been studying bed load interception technology, developed and patented by Streamside Systems (an Ohio company) as one possible tool in an array of potential sediment management techniques. Bed load interception would be used to catch sediment before it enters and settles in the ship channel.
As part of its strategic leadership for sediment management, the Port of Cleveland has been studying bed load interception technology, developed and patented by Streamside Systems (an Ohio company) as one possible tool in an array of potential sediment management techniques. Bed load interception would be used to catch sediment before it enters and settles in the ship channel. Key benefits of bed load interception: Bed load interception is significantly less costly than dredging and placement in CDFs (less than one quarter of typical dredging and disposal costs) Reducing dredging requirements by bed load interception extends the useful life of CDFs. Bed load sediment is cleaner. It has significantly less latent toxicity and is less impacted by the effects of urban run-off and discharge from Combined Sewer Overflows. Clean, granular, harvested bed load is well suited for a wide variety of beneficial upland uses.
Empirical Confirmation - In the spring of 2012 the Port Authority sponsored a study by the University of Akron. The study included: Temporary placement and operation of passive bed load sediment collectors from Streamside Systems, in two of locations in the natural flowing river (river mile 11.5 at Kurtz Bros. and river mile 21 in Cuyahoga Valley National Park. Both sites were upstream of the Ship Channel and also above the influence of discharges from Combine Sewer overflows; Daily retrieval of bed load materials from the collectors; Characterization of the collected materials for grain size distribution and related engineering properties; Toxicity analysis (soil chemistry) by a certified lab of the benthic and bed load sediments. Results: Confirmed the 2010 study that Cuyahoga River sediments are susceptible to bed load interception. Bed load interception appears to be a viable technique for reducing overall dredging quantities. The Port Authority is shaping the details for a larger, longer Pilot Study. Grain size distribution indicates material that is suitable of a variety of uses (see Table 1) Harvested bed load is cleaner than background soils (see Table 2) and is considered by OEPA to be suitable for unrestricted uses.
Cuyahoga River sediments are susceptible to bed load interception. Grain size distribution indicates material that is suitable for a variety of beneficial uses.
Harvested Bed load is cleaner than undisturbed background soils typically found in the region. OEPA has indicated bed load sediments meet Standards for placement in residential settings. The Port Authority and OEPA are very encouraged by the results.
These results will be incorporated into the hydrodynamic model being developed for the river. I would like to introduce Pete Kotulak of Moffat and Nichol. Pete will present the status of the hydrodynamic model.

While some beneficial use projects have been implemented, there is a need for additional sediment sampling and characterization activities that could be completed in the river and more reach-specific sediment management guidelines that might support the unrestricted beneficial use of all, or a portion of dredged material from the river in upland or open-lake placement locations.

According to USACE, recent sediment data collected in 2010 suggests that the sediment quality in the upper reach of the Cuyahoga River has improved (Stations 799+00 to the Upper Turning Basin at Station 736+00). As a result, part of the USACE’s focus for the 2012 sampling is to complete 5-year sampling event of channel for bulk chemistry analyses and further characterize the sediments in the Upper reach to determine whether they are suitable for open-lake placement The USACE samples Cleveland Harbor every 5 years 2002 2007 2012 ERDC completed supplemental sampling in 2010 as part of a beneficial use suitability study
2012 sampling locations included several general management areas. 1) Upper River Reach (Station 736+00 to Station 799+00) Approximately 70% of the annual dredging occurs here Bottom material that is dredged from stations 799+00 to Station 787+00 may contain significant fractions of sand and gravel. However, it does not meet OEPA criteria for littoral nourishment (USACE, WQC Application) Material within this area has the potential to meet open-lake placement Federal guidelines 3 dredged material management units, 5 discrete samples and 1 composite for each DMMU
USACE Assumptions for the remaining areas: Material within these areas is dredged less frequently USACE believes material is not likely to meet open-lake placement guidelines 2) Middle River Reach (Station 736+00 to Station 606+00) 5 discrete sediment samples, 1 composite for elutriate testing only 3) Lower River Reach (Station 606+00 to mouth of the River at Outer Harbor) 6 discrete sediment samples, 1 composite for elutriate testing only 4) Old River Reach (Entirely within Old River Channel) 3 discrete sediment samples, 1 composite for elutriate testing only All composite sediment samples analyzed for general bulk chemistry including: Metals PAHs Pesticides PCBS Cyanide Ammonia Total Kjehldahl Nitrogen Total phosphorus TOC BTEX Total petroleum hydrocarbons % Moisture Organic Matter Grain Size
According to the USACE, recent sediment data collected in 2010 suggests that the sediment quality in the upper reach of the Cuyahoga River has improved over the years (USACE, 2012). As a result, USACE focused the 2012 sampling efforts, in part, on characterizing the suitability of sediments in the upper reach for open-lake placement. A recent review of the USACE website shows that 2012 sediment data has not yet been released. Some observations regarding the USACE sampling plan discussed during the meeting include: All historic samples were generally focused in the center of the channel; Sampling did not consider shoulder areas, or target depositional/erosional areas; Sampling points were not biased toward potential upland COC source areas (e.g., existing outfalls, industrial operations, etc.); Sampling did not include upstream locations; and Chemical analyses apparently only evaluate open-lake placement suitability of upper reach materials and may not be representative of full dredge depth.
Review of 2010 data identified the following parameters that exceeded one or more SQGs: Arsenic Mercury Silver Cadmium Cobalt Chromium Lead Nickel Copper Zinc Benzoapyrene Most exceedances occurred in Upper Reach
There is a need to fully characterize sediment both within the federal navigation channel as well as areas outside of the federal navigation channel, such as the shoulders and upstream areas. Additionally, sediment sampling should consider potential upland COC source areas. To address these limitations, and with feedback/input from Ohio EPA , Hull developed a systematic approach for the completion of a comprehensive sediment characterization through identification of potential COC source areas, evaluation of recent pollutant discharges, and the incorporation of a hydrodynamic model to integrate depositional/erosional areas in the sampling approach. Hull completed a general review of several data sources to identify the locations of various potential COC source areas (e.g. outfalls). These data sources include the Northeast Ohio Regional Sewer District, Ohio EPA, U.S. EPA, and Cleveland Water Pollution Control. Hull also used the U.S. EPA Discharge Monitoring Evaluation (DMR) Tool to evaluate the relative amount and location of pollutants discharged in 2010 to the Cuyahoga River within the project area. While this tool includes discharge information for many NPDES permitted industrial and municipal point source facilities, it does not include all facilities, discharges, or monitoring data under the NPDES program. Additionally, it does not include other Clean Water Act releases such as biosolids and wet-weather discharges. However, this information is useful in qualitatively evaluating potential areas relatively of high pollutant loading. Much of the pollutant loading, according to the U.S. EPA DMR Tool results, occurs upstream of the federal navigation channel and within the Upper River Reach of the federal navigation channel. Pollutants reported in these areas included copper, cyanide, lead, nickel, oil and grease, and zinc.
Hull has developed a preliminary sediment sampling approach to facilitate a project partnership to pursue funding for a sediment characterization project. Since the material outside of the federal channel has not been fully characterized yet, Hull believes the first step should be to complete a comprehensive baseline evaluation of the sediment outside of the federal channel. The proposed sediment sampling approach would include general testing for chemical and physical parameters as illustrated by this figure. The general testing results would be reviewed and potential COCs would be identified. Focused bioavailability and toxicity testing would be completed for specific areas identified based on the results of the general testing. The final number and location of samples will be determined after the COC potential source areas are identified and the hydrodynamic transport model is complete. Sampling locations will be selected to better characterize the navigation channel as well as shoulder and upstream areas outside of the federal channel. Final sampling locations and sample depths will be established after the hydrodynamic model is completed and stakeholder feedback is incorporated. This baseline sediment evaluation would support the development of a sediment testing and evaluation program to facilitate the beneficial use of dredged material. Further, this program would be periodically evaluated to ensure that it is protective of human health and the environment. Additional testing programs could also be developed based on the specific end use of the dredged material. Finally, subsequent pre-dredging sampling could be coordinated so that data could be used for multiple purposes in addition to federal dredging sediment evaluations. A comprehensive sediment sampling characterization and management approach would incorporate stakeholder data requirements into a unified sediment sampling approach, reducing the time lag of sharing data and leading to a better mutual understanding of the benefits of a comprehensive sediment sampling and management strategy.
