In July of 2018 the project secured an independent Environmental Impact Assessment.

With the thorough analysis performed by independent environmental consultancy CSA Ocean Sciences now complete, The Ocean Cleanup has issued the results of the Environmental Impact Assessment (EIA) for System 001.

 

The purpose of the EIA is to address the potential environmental risks of various factors related to the deployment of the first ocean cleanup system. Overall, the conclusions indicate a low or negligible risk for the implementation of System 001 in the Great Pacific Garbage Patch.

 

THE EIA EXPLAINED

An Environmental Impact Assessment (EIA) is a study to evaluate the environmental, social and economic impacts a project may have on a range of resources during its life cycle. The EIA is used to identify possible risks and offers mitigation options before the project takes place.

 

Considered in this EIA are the multiple factors related to the deployment of The Ocean Cleanup system and their potential impact; these include:

- towing operations,
- entanglement and entrapment,
- attraction/ingestion of plastics,
- interactions or collisions with other vessels,
- noise and lights,
- and the loss of debris.

The potential areas of impact included a variety of marine life and birds, vessels not in connection with The Ocean Cleanup and protected areas.

 

WHY THEY CONDUCTED AN EIA

Because the deployment of the system will take place primarily in international waters, except for routine towing, there are no requirements for this assessment. Nevertheless, in the interest of transparency, and to develop a deeper understanding of the interactions between our operations and the environment, an EIA was performed; which meets the 1999 International Association for Impact Assessment Principles of Environmental Impact Assessment Best Practices (IAIA, 1999).

 

RESULTS

The EIA identifies both initial and residual environmental impacts-i.e., effects resulting before and after the application of mitigation measures. Mitigation measures are defined for all impacts, regardless of the severity. For the sixteen environmental and human resources considered, 29 impact factors were identified and analyzed in depth, and all but one were determined to have “Low” or “Negligible” impacts resulting from project activities (even before the application of mitigation measures). One “Medium” risk was identified; potential attraction of sea turtles to the cleanup system and/or ingestion of plastics due to the concentration near the floating screen. There were no “High” impacts on any resources resulting from the project.

GOING FORWARD

While the baseline today is that hundreds of thousands of whales, seals, sea turtles and sea birds die every year from entanglement and ingestion of ocean plastic, The Ocean Cleanup can conduct its cleanup activities with greater confidence and a broader understanding now that we possess the information presented in the EIA. Although the identified impacts pose minimal risk, we have planned for extensive on-site monitoring of the system and the surrounding environment during the first year of deployment. In addition, several safety and mitigation measures will be tested on System 001 during the plastic removal procedure.

We will continue to share real-world environmental findings when the cleanup operation of the Great Pacific Garbage Patch has commenced later this year.

Although not required by law, The Ocean Cleanup has commissioned an independent EIA. This follows extensive engagement with regulators, experts, and others. We will continue to consider feedback and respond as frequently as time and our limited resources permit.

Environmental Impact Assessment 23 JULY 2018

 

"Activities from the proposed towing and deployment will produce emissions from internal combustion engines, including greenhouse gases, and varying amounts of other pollutants such as carbon monoxide, oxides of nitrogen, and sulfur, volatile organic compounds, and particulate matter.


The geographic location of operations ranges from Alameda Island in San Francisco Bay to the proposed deployment location approximately 1,880 km (1,015 nmi) from shore in the EPGP.

 

The amount of air pollutants and greenhouse gases generated during The Ocean Cleanup activities will depend primarily on the number, design, and size of the vessels; the size of engines and generators on the vessels; the distance traversed under power; and overall duration of the activities, however, due to the limited extent and duration of activities, the amount of pollutants is expected to be nominal."

 

That is according to this Assessment, but no figures are provided for the reader to be able to agree or disagree. For example, the Report suggests: "..a limited duration and extent of activities."

 

But is that true?

 

Surely we need to know the ratio of Greenhouse Gas production and the cost of fuels, in order to be able to quantify the environmental costs as related to plastic recovered.

Air Quality

"Potential impacts from emissions on air quality are expected to be negligible. Vessels (towing, monitoring, and debris retrieval), machinery, and equipment involved in The Ocean Cleanup activities will emit a variety of air pollutants, including nitrogen oxides, sulfur oxides, particulate matter, volatile organic compounds, and carbon monoxide, as well as greenhouse gases (e.g., carbon dioxide) primarily from combustion of fossil fuels for propulsion and power generation.

 

The amount of air pollutants and greenhouse gases generated during The Ocean Cleanup activities will depend primarily on the number, design, and size of the vessels; the size of engines and generators on the vessels; the distance traversed under power; and overall duration of the activities, however, due to the limited extent and duration of activities, the amount of pollutants is expected to be nominal.

 

The Ocean Cleanup is currently performing a Life Cycle Assessment to full estimate greenhouse gas emissions from the towing and deployment. Due to the novelty of the project, the Assessment will last the full year of the deployment and will help The Ocean Cleanup to quantify actual impacts to air quality from project emissions and to identify possible mitigation measures for future activities.

 

Air emissions from The Ocean Cleanup vessels will contribute nominal amounts of pollutants to the emissions inventories for vessels in the waters offshore San Francisco. Air quality could be temporarily affected by an accidental fuel spill in the immediate vicinity of the spill, but due to the small volume of a potential spill and the high volatility of refined fuels, any impacts on air quality are expected to be negligible. For these reasons, a more extensive analysis of air quality emissions associated with anticipated operations will not be performed as part of this EIA."

 

We are pleased to see that there will be a log of fuels used. This should also include the carbon and food footprints of the crews.

 

Where we are advocates of ocean cleaning, it must be that this information should be provided in the interests of transparency. Not to do so might raise a few eyebrows.

 

This report is interesting as it underscores some of the issues identified in the operation of SeaVax and RiverVax machines.

 

 

OPERATIONAL MOVEMENTS

 

1. Fuel (bunker heavy oil) used in boom towing operations to and from start & end.

2. Fuel (diesel) used by fishing vessels in netting and landing plastic from the booms.

3. Fuel used in providing life support (though could be included in 1. above.

4. Food and other provisioning for support boats.

 

MITIGATION & OFFSET

 

By way of mitigation when comparing to the SeaVax and SeaBin systems (for example) it is important to look at how much energy it takes in total to land plastic ashore, or to deposit with other ocean based treatment facilities.

 

 

PROJECT BACKGROUND

The Ocean Cleanup has developed a prototype passive drifting system (The Ocean Cleanup System or OCS) to collect buoyant plastic debris from the Great Pacific Garbage Patch. There are multiple areas where the debris accumulates, and The Ocean Cleanup is focusing on the area known as the Eastern Pacific Garbage Patch (EPGP) which is located roughly midway between California and Hawaii within the North Pacific Subtropical Gyre.

 

The Ocean Cleanup is planning a year-long deployment in the EPGP in a location approximately 1,880 km (1,015 nmi) from San Francisco. Assembly of the OCS has begun on Alemeda Island in the San Francisco Bay and The Ocean Cleanup estimates that it will be completed in mid-2018.

 

Prior to deployment, The Ocean Cleanup will conduct a Tow Test outside of the shipping channel and protected areas offshore San Francisco and a trial deployment at a currently undetermined location outside of the United States Exclusive Economic Zone (U.S. EEZ) (>370 km [200 nmi] from the California coast) that will last approximately two weeks.

 

After the Tow Test and trial deployment, the OCS will be towed to the EPGP and it is estimated that this will require 22 days of towing to reach the designated location.

Purpose and Need

The Ocean Cleanup voluntarily chose to conduct an Environmental Impact Assessment (EIA) to properly assess potential impacts and ensure that mitigation measures could be implemented to reduce or eliminate any substantial identified impacts. The Tow Test will utilize a U.S. flagged vessel, while the vessel used for the Pacific Trial and deployment to the EPGP will not be U.S. flagged and will not be completed by U.S. citizens. All of the proposed activities (except the Tow Test) will occur in international waters outside of the U.S. EEZ. Because no permits are required, the proposed activities do not fall under regulatory oversight of the United States National Environmental Policy Act and no environmental impact assessment (EIA) is required. In the absence of regulatory requirements, this EIA was created to meet the 1999 International Association for Impact Assessment Principles of Environmental Impact Assessment Best Practices (IAIA, 1999).

EIA Summary

The various components of the activities being proposed by The Ocean Cleanup (including towing
operations from San Francisco Bay and a year-long deployment in the EPGP) have been evaluated for
potential impacts to the biological, physical, chemical and social environment. A total of 16 resource
areas were considered, including:

• Air Quality
• Water Quality
• Sediment Quality
Plankton
• Fish and Fishery Resources
• Benthic Communities
• Marine Mammals
• Sea Turtles
• Coastal and Oceanic Birds
• Protected Areas
• Biodiversity
• Archaeological Resources
• Commercial and Military Vessels
• Human Resources, Land Use, and Economics
• Recreational Resources and Tourism
• Physical ocean factors


A preliminary screening was conducted to identify the resources at risk from the towing and deployment of the OCS in the EPGP. In this preliminary analysis, the level of impact associated with each interaction was categorized as “potential impact for analysis” (e.g., a measurable impact to a resource is predicted) or “no impact expected” (i.e., no measurable impact to a resource is predicted).

 

Several resources were identified as having no expected impacts from the proposed activities and were removed from further analysis. Resource areas that were screened out included air quality; sediment quality; water quality; benthic communities; biodiversity; human resources, land use and economics; recreational resources and tourism; and physical oceanography.

 

The remaining resource areas were characterized based on review and summarization of pertinent data sources, including peer-reviewed literature, government publications, and applicable datasets. The impact assessment methodology was conducted from a risk-based perspective to determine the overall significance of each potential impact based on its consequence and likelihood (Table ES-1).

Impacts from routine operations resulting from the proposed activities are expected to occur based
on a series of impact producing factors, including:

• Towing Operations
• OCS – Entanglement/Entrapment
• OCS – Attraction/Ingestion of Plastics
• Vessel – Physical Presence/Strikes
• Noise and Lights
• Loss of Debris

The Environmental Impact Assessment also addressed potential impacts associated with an accidental fuel spill. Resources potentially affected by each impact producing factor were subsequently evaluated. The impact assessment process involved: 1) an initial determination of impact, without any mitigation; 2) an identification and application of appropriate mitigation measures; and 3) a determination of impact after mitigation was applied (i.e., residual impact). Impacts resulting from routine operations associated with the proposed activities were rated, in terms of overall impact significance using an alphanumeric and color code, as follows:

Impacts rated Medium or High were considered primary candidates for mitigation, while those rated Negligible or Low were of secondary importance from a mitigation perspective. In application, mitigation measures were considered for all impacts, regardless of impact level. The initial analysis of routine operations (i.e., prior to application of mitigation measures) produced impact

determinations that were predominately in the Negligible or Low categories. No High level impacts
were noted. A comprehensive discussion of the mitigation measures and corporate/subcontractor
policies that The Ocean Cleanup will follow during their proposed activities is presented under
separate cover in an Environmental Management Plan.

 

Impacts from an accidental fuel spill were identified based on the accidental release of diesel fuel. Diesel fuel released into the marine environment undergoes rapid weathering, including evaporation and dissolution. Given the relatively small potential spill volume and weathering factors, the impacts to various resources from a fuel spill release were routinely rated Negligible or Low. Impacts from an accidental diesel fuel spill are expected to be localized and relatively short-term (due to its high volatility and dispersibility).

 

A tabular summary of impacts from routine operations and an accidental fuel spill is presented in Table ES-2. When proper mitigation measures, maritime regulations, and industry best practices are applied, the significance of potential impacts of the proposed activities will generally be Negligible or Low. Moreover, the long-term positive impacts as a result of removing large amounts of floating plastic from the EPGP will likely provide a beneficial impact to biological resources in the region.

 

 

INTRODUCTION

The Ocean Cleanup has developed a prototype passive drifting system (the Ocean Cleanup System or
OCS) to collect buoyant plastic debris from the Great Pacific Garbage Patch. The Great Pacific Garbage Patch refers to areas in the Pacific Ocean that act as natural gathering points where rotating currents, winds, and other ocean features converge to accumulate marine debris. There are multiple areas where the debris accumulates, and The Ocean Cleanup is focusing on the area known as the Eastern Pacific Garbage Patch (EPGP) which is located roughly midway between California and Hawaii within the North Pacific Subtropical Gyre (NPSG) (Figure 1-1).

The Ocean Cleanup is planning an approximately year-long deployment in the EPGP in a location approximately 1,880 km (1,015 nmi) from San Francisco. This Environmental Impact Assessment (EIA) presents the existing environmental conditions of the area that may be potentially impacted by the proposed project which includes a Tow Test, followed by towing operations from San Francisco Bay to the Pacific trial location outside the United States Exclusive Economic Zone (U.S. EEZ) and finally to a location within the EPGP. The EIA provides a description of the Tow Test, towing operations, and deployment of the OCS in the EPGP and an assessment of potential environmental impacts that may result from operations together with recommendations to manage, mitigate, and monitor those impacts. The EIA is organized as follows:

• The Executive Summary is a short, non-technical summary of the project that briefly describes the baseline environment, the risk assessment methodology, potentially significant impacts, and mitigation measures.


• Chapter 1.0, Introduction, presents the project, including objectives, location, and scheduling. This chapter discusses the purpose, scope, and organization of the EIA.

 

• Chapter 2.0, Project Description, provides a detailed narrative of the proposed activities, the waste and emissions that may be associated with such a project, and the purpose of the project. Planned activities that may affect the environment are described in sufficient detail to support impact assessment.

 

• Chapter 3.0, Legislative and Regulatory Environment, identifies and describes the national and international laws, regulations, guidelines, protocols and standards that were considered as potentially applicable to the proposed project. This chapter summarizes specific permitting requirements that were considered in relation to the proposed project.

 

• Chapter 4.0, Description of the Existing Environment, characterizes the conditions of the project area environment in terms of the physical, chemical, and biological components. This chapter presents key information needed to understand the environmental setting, identify valued ecosystem components, and assess impacts. This chapter also provides a preliminary screening of resources to eliminate resources with little or no potential for adverse or significant impact from the detailed analysis. The text is organized as follows:

 

o Preliminary Screening of Activities and Affected Resources;
o Data Sources;
o Biological Environment; and
o Social Environment.

• Chapter 5.0, Potential Environmental Impacts, identifies and assesses the potential environmental impacts from this proposed project, both beneficial and negative. The chapter includes the basis for impact designation, impacts from routine operations, and impacts from potential accidents or upsets. Cumulative impacts are also discussed.

 

• Chapter 6.0, Conclusion, summarizes the findings of the EIA.

 

• Chapter 7.0, Literature Cited, lists all published and unpublished data sources in this EIA.

 

• Appendix, presents technical data used in support of the EIA.
