California Ocean Protection Council Announces West Coast Ocean Acidification and Hypoxia Science Panel

California and Oregon are joining forces to help address ocean acidification and hypoxia, a West Coast-wide threat to our shared marine and coastal ecosystems. The California Natural Resources Agency, on behalf of the California Ocean Protection Council (OPC), today signed a Memorandum of Understanding with the state of Oregon to jointly sponsor a high-level science panel to help address the issue of ocean acidification and hypoxia.  The West Coast Ocean Acidification and Hypoxia Science Panel will provide state-level decision makers with the knowledge needed to evaluate and develop action plans for these complex issues. The science panel will also identify the research and monitoring needed to contribute to a West Coast-wide assessment of ocean acidification and hypoxia, and address information and data gaps critical to resource management decisions.

Ocean Acidification and Hypoxia

Ocean acidification and hypoxia, two phenomena often coupled for a variety of biological and oceanographic reasons, have the potential for profound impacts on living marine resources. Scientists have already demonstrated serious impacts on shell-building organisms, among others, and severe effects on the shellfish industry have been documented in the Pacific Northwest. In California, resource managers, stakeholders, tribes and citizens are beginning to express concerns about these emerging threats to local ecosystems, communities, and coastal economies.

Ocean Protection Council and Partner Efforts to Address Complex Processes

California is uniquely situated to advance collective understanding about ocean acidification and hypoxia and to use this knowledge to inform multiple management strategies. The California Ocean Protection Council and the California Ocean Science Trust are working hand-in-hand to elevate attention to ocean acidification and hypoxia in several arenas. Through its Cabinet-level leadership, the Ocean Protection Council is working both within the state and with West Coast leaders to identify appropriate responses to these coast-wide phenomena. This work is exemplified by the interdisciplinary West Coast Ocean Acidification and Hypoxia Science Panel, convened at the request of the Ocean Protection Council by the California Ocean Science Trust to provide decision makers with the knowledge needed to thoughtfully evaluate effective management actions.

California’s investment in a network of marine protected areas (MPAs) provides opportunities to study the early impacts of ocean acidification, hypoxia and other stressors, while bolstering the resilience of California’s ocean ecosystems in the face of these emerging threats. The Ocean Protection Council and the Ocean Science Trust are positioned at the nexus between science and policy, and this collaboration brings emerging science to bear on evolving policy and management responses within California and across the West Coast. Several key efforts are described below.

A West Coast Leadership Priority

The Pacific Coast Collaborative and West Coast Governors Alliance on Ocean Health recognize ocean acidification as a priority ocean and coastal health issue, given the added vulnerability of the West Coast. In December 2013, the West Coast Governors and the Premier of British Columbia mobilized to provide a joint letter to President Obama and Prime Minister Harper in fulfillment of an initial action called for in the Pacific Coast Action Plan on Climate and Energy to enlist support for research on ocean acidification. This letter raises awareness of ocean acidification at the highest levels, promotes the collaborative efforts and leadership from the West Coast, and requests specific action and enhanced support from our federal partners. In response, a convening of state, provincial, and federal leaders to develop a joint strategy to address ocean acidification and hypoxia is currently being planned for later in 2014. The OPC Executive Director is in close contact with counterparts in Oregon, Washington and British Columbia on this issue.

Recognizing the west coast-wide nature of the potential impacts, the West Coast Ocean Acidification and Hypoxia Science Panel is composed of leading scientists from California, Oregon, Washington and British Columbia who will look for driving mechanisms that are common to the entire Pacific coast. The Panel will build upon the work of the Washington State Ocean Acidification Blue Ribbon Panel, address information and data gaps critical to resource management decisions, and identify the research and monitoring needed to contribute to a west coast-wide assessment of ocean acidification and hypoxia.

C-CAN is an interdisciplinary collaboration among managers, scientists, and industry working to coordinate and enhance acidification monitoring along the entire west coast. The OPC Science Advisor (OST Executive Director) and several of the West Coast Ocean Acidification and Hypoxia Science Panelists participate on the C-CAN Steering Committee. C-CAN works with the regional ocean observing system associations, including the Central and Northern California Ocean Observing System (CenCOOS) and the Southern California Coastal Ocean Observing System (SCCOOS), to coordinate and encourage development of an acidification monitoring network for that serves publicly available data through the sharing of resources. C-CAN has produced a vision document describing how this data could be used by the management community, as well as a core principles document that describes the elements of a comprehensive and efficient monitoring network.

Supporting Scientific Partnerships to Enhance Understanding

The OPC has committed support to improve scientific understanding of acidification and hypoxia and the impacts to biological resources. The OPC is funding research through California Sea Grant to provide insights into effects of the upwelling of acidic waters and implications for shellfish along the California coast, and recently approved funding for scientists to perform integrated modeling of acidification, hypoxia, and nutrient inputs in the coastal ocean. The project will enhance current regional oceanographic modeling systems enabling a more comprehensive and consistent evaluation of both anthropogenic and climatic perturbations on near-shore physical, chemical, and biological conditions.

Ocean and coastal water quality

Beachgoers and wildlife need the same thing – clean ocean water. A relaxing day enjoying California’s waters can easily be undone by beach closures or widespread harmful algal blooms. With California’s coastal and ocean waters extending from the top of the watersheds to the deep waters off the coast, the Ocean Protection Council has made improving water quality a top priority.

The ocean is usually the end point of land-based pollutants that flow from coastal watersheds.  Nearshore impairment of water quality can result from municipal sewage discharges, industrial waste discharges, dredge spoils, and agricultural and urban runoff.  When water quality is poor, the ability of coastal ecosystems to support healthy fisheries, aquaculture, recreational opportunities, and other beneficial uses is undermined. The OPC is working to improve water quality through assisting agencies who enforce pollution control, encouraging new approaches to reduce non-point source pollution from land and point source pollution from vessels, eliminating harmful impacts from once-through cooling at power plants, boosting water quality testing programs and warning systems, and reducing marine debris.

Objectives of the Ocean and Coastal Water Quality Section of the 2006 – 2011 OPC strategic plan:

Objective stormwater drainage pipe1: Enforce Pollution Controls

To reduce pollution, we must improve how California’s water quality laws are enforced. Several agencies have responsibility to keep our water clean but they may be hampered by funding or conflicting legislation. The OPC seeks to coordinate and support the agencies and their programs to enforce existing water quality laws. For example, the OPC is working with the Department of Fish and Game and the Los Angeles Regional Water Quality Control Board to support overlapping goals of improving water quality and protecting fish, wildlife and other coastal resources.

Objective 2: Innovation

Since the passage of the Clean Water Act in 1972, California has made great strides in reducing point source pollution from industrial and other operations.  Yet, there has been less progress in reducing pollutants from non-point sources, such as storm water flows from heavily paved urban environments, construction sites, and agricultural operations. Innovative approaches are needed to continue to clean up our waterways. To that end, the OPC has supported expanded use of low-impact development through a 2008 resolution and accompanying projects.

Objective 3: Once-thEl Segundorough Cooling

In California, 21 coastal power plants use once-through cooling, a process in which large volumes of seawater are drawn into the power plant to condense steam created during electricity generation. When this occurs, small organisms such as plankton and larvae are drawn into the cooling system and killed, and larger fish are pinned against the water intake screens.  Warm water is also discharged back into the ocean, which harms the resident sea life. The OPC has supported the work of the State Water Resources Control Board to eliminate once-through cooling in California since 2006 with the passage of the first OPC resolution.

Objective 4: Water Quality TestingCape Rodney NZ credit Miriam Godfrey

Planning to enjoy a day at California’s coast can be ruined when a beach is closed from contaminated ocean water. Rapid indicators of pathogen contamination could provide for more timely notice of beach closures and openings. The OPC has targeted predicting harmful algal blooms (HABs) as one of the first improvements to water quality testing off the California coast.

Objective 5: Marine Debris

Ocean ConservancyThe accumulation of land-based litter and ocean-based derelict fishing gear in the ocean has garnered much attention in the media. Scientific studies have found more than 260 marine species suffer from marine debris by ingestion, starvation, suffocation, infection, drowning, and entanglement. Risks from toxins and contaminants of emerging concern (CECs) associated with marine debris are a growing research area. The OPC began to address marine debris and toxins with a 2007 resolution that seeks to reduce ocean and coastal debris and its impacts to ocean ecosystems.

Objective 6: Vessel Pollution

Ships are a vital part of the ocean economy from commercial transportation to recreational use. California’s myriad of ports and harbors host pleasure craft, cruise ships, and oil tankers, all of which can act as individual sources of pollution to the sea. The OPC seeks to reduce and eliminate pollution from vessels such as developing effective alternatives to anti-fouling hull paints.

Toxicological Profiles

Our industrial society uses a plethora of chemicals to survive. Inorganic and organic compounds are used for dry-cleaning, and producing rubber products, PVC pipes and plastic packaging. Some of these chemicals give plastics their desirable characteristics of flexibility and durability. However, most of these chemicals do not occur naturally in the environment and recently, more attention is being given to how those chemicals affect human health as they leach from the plastic products.Three chemicals were investigated in this project: bisphenol-a (BPA), nonylphenol (NP) and di-(2-ethylhexyl) phthalate (DEHP). BPA has received much media attention as it is found in baby and water bottles, sports equipment, medical devices, CDs and household electronics. NP is used as an industrial cleaning agent and a stabilizer of the chemical process during plastic and rubber manufacturing. DEHP is used commonly used for making PVC more flexible in many products, such as packaging, furniture upholstery, shower curtains, garden hoses and medical tubing. Research shows these chemicals can disrupt reproductive and developmental systems, increase cancer risks and damage the immune systems of experimental laboratory animals. The effects on marine ecosystems, where many plastic items with these chemical accumulate as litter, have yet to receive the same level of research so the impacts to marine animal health are mostly unknown.

Background

The OPC Marine Debris Resolution item #11 encourages developing a plan for the phased ban of the most toxic types of plastic packaging. Part of that plan involves determining the risks to human and marine animal health from specific chemicals. The OPC turned to the expertise of the Office of Environmental Health Hazard Assessment (OEHHA), a department of California Environmental Protection Agency whose mission is to protect and enhance public health and the environment by scientific evaluation of risks posed by hazardous substances.  OEHHA developed toxicological profile reports of BPA, NP and DEHP to inform how these chemicals affect the marine ecosystem.

Funding

The OPC used $155,684 from the California Clean Water, Clean Air, Safe Neighborhood Parks and Coastal Protection Fund (Proposition 40) to fund this project.

Preventing Ocean Litter

Ocean litter – also commonly referred to as “marine debris” – is a persistent and growing problem worldwide that significantly impacts the health and beauty of our oceans and beaches. It poses serious threats to marine wildlife, including sea birds, turtles and mammals such as dolphins and whales, as well as human health and welfare. Scientific research demonstrates that debris in the oceans is increasing at an alarming rate: plastic debris in an area north of Hawaii known as the Northwest Pacific Gyre has increased 5-fold in the last 10 years. In the Southern Ocean, the amount of plastic debris increased 100 times during the early 1990s. These are just a few examples of the recent marked increase in marine debris. Researchers estimate that 80% of marine debris comes from land-based sources, particularly trash and plastic litter in urban runoff, and the generation of trash and waste is increasing.On November 20, 2008, the Ocean Protection Council (OPC) adopted the final “Implementation Strategy to Reduce and Prevent Ocean Litter”. The document was created in response to the OPC’s February 2007 resolution that called for a plan of action to reduce and prevent marine debris. The report aims to prompt a change in how California generates, handles and disposes items that frequently land in our ocean. The implementation strategy offers sixteen recommendations, ranging from banning smoking on state beaches to anti-litter education and clean-up initiatives, with three priority actions that focus on reducing litter through direct economic actions. At the core is the goal of reducing the amount of litter that accumulates in the ocean, particularly the 60-80% that is lightweight and buoyant plastic material. This litter kills marine life, including endangered species, transports invasive species and toxic pollutants, and damages the aesthetics of our beaches and the sea.

The top three priority actions of the implementation strategy would remake California’s relationship with frequently used plastics and commonly littered items. The first priority action is to create a producer take-back program, or Extended Producer Responsibility (EPR), for convenience food packaging. Successful EPR programs reduce waste by motivating manufacturers and distributors to use less packaging and more recyclable types of materials. The second priority action is a ban on polystyrene take-out food containers and a fee on single-use plastic and paper grocery bags. The goal behind this proposed fee and ban is to encourage a shift toward reusable bags and containers that are safer and less damaging to the marine environment. The third priority action recommends a fee be placed on commonly littered products that are not suitable for a take-back program or ban. The goal is to provide an incentive to consumers to buy less environmentally damaging products and to create a source of funds that can be used for new and improved litter-related programs, such as stricter enforcement of litter laws, increased clean up efforts, or alternative product development.

The OPC adopted the implementation strategy to encourage manufacturers, distributors, environmental groups, regulatory agencies and the public to reassess how our actions contribute to the growing problem of marine debris. Written with the guidance of the Marine Debris Steering Committee, the report is the first comprehensive plan that involves all Californians in a broad effort to curb ocean litter.

Plastics Substance Flow Accounts

The OPC Marine Debris Resolution item #3 encourages new innovations to reduce plastic waste in the marine environment. One innovation is to identify alternatives that would biodegrade in the ocean and do not contain toxic materials. However, the effects and life-cycle of our current set of plastics need to be understood so alternatives can be developed.

Researchers at Chico State University calculated preliminary substance flow accounts for waste related to plastic packaging and products that may contribute to marine debris.  The work was coordinated in consultation with a project officer from the California Department of Toxic Substances Control (DTSC). The overall goal of the project was to understand the potential toxic hazards posed by plastic packaging waste in California’s aquatic environments through the creation of state-level substance flow accounts for plastic products of key concern.

The research aims were:

  1. identify and track the flows of the main thermoplastic resins (PET, PE, PVC, PP, PS) and all relevant additives through all relevant sectors
  2. identify emerging “safer substitutes”
  3. evaluate the methods and recommend next steps

Low-Impact Development (LID)

As more impervious surfaces – roads, parking lots and buildings – are built in a watershed, more runoff is produced that is contaminated with oil, grease, metals, trash, bacteria, and other pollutants.  This polluted runoff enters our waterways and contributes to beach closures, depressed fish populations and harmful algal blooms, all of which hurt our economy directly or indirectly. Increased flow may cause stream beds and banks to erode, damaging or eliminating stream habitat and carrying sediment downstream.  Low-Impact Development (LID) is a set of stormwater management strategies that reduces impervious surfaces, treats runoff, controls runoff peaks and durations, and thereby helps protect water quality and stream resource integrity.

Background

LID works.  Its implementation is being fast-tracked by the federal government (most notably, the Department of Defense) and in many states.  In California, the State and Regional Water Boards are already incorporating LID into their Statewide Construction and Municipal NPDES permit requirements.  In early January 2008, the State Board released a policy analysis that examines the State’s primary mechanisms of regulating stormwater runoff and considers how LID approaches could be used for compliance purposes.  Many local communities in California are also adopting LID requirements and practices.

LID can also benefit the business community.  In December 2007, the U.S. Environmental Protection Agency released a new report entitled “Reducing Stormwater Costs through Low Impact Development (LID) Strategies and Practices.”  The report contains 17 case studies from across North America that show the economic viability of LID practices.  The report demonstrates that, in almost all cases, LID can reduce project costs while improving environmental performance. Total capital savings ranged from 15 to 80 percent, with one exception in which LID project costs were higher than conventional stormwater management costs. As LID practices become more common, it is likely that they will become cheaper to use.

Promoting LID in California was included in the 2008 OPC program priorities and at the February 2008 meeting, a report was presented to the Council exploring state and local policies that encourage or require LID. At the May 15, 2008 meeting, the OPC adopted a resolution regarding LID. As stated in the resolution, the OPC found LID to be a practicable and superior approach to minimizing and mitigating increases in runoff and runoff pollutants due to land development. Further, LID is cost-effective, has many ancillary benefits, and in most cases can be executed at lower cost than conventional drainage systems. Three topics were identified for action by the OPC to promote LID: state leadership, state regulatory action, and incentives, technical support and research. The resolution also included various items the OPC could consider funding to promote LID. Since the adoption of the resolution, the OPC has engaged with the Natural Resources Agency, California EPA, the Office of Planning and Research, Caltrans, the Building Standards Commission and the Department of Water Resources to encourage incorporation of the principles of LID in projects and standards. Standards for regulatory actions are also being developed by the State Water Board with assistance from the California Coastal Commission and the OPC.

Outcomes

The OPC awarded funds to Tetra Tech to examine the state and local policies that encourage or require the use of LID.  The final report,  “State and Local Policies Encouraging or Requiring Low Impact Development in California” (January 2008 ) serves as a clearinghouse for LID activities throughout the state, although as LID becomes more widespread, newer projects are not described.
