Initial Community Assessment of Plans to establish a tidal energy device evaluation center in the vicinity of Castine Harbor and the Bagaduce Narrows
Ronald E. Beard, Coordinator, Maine Solutions and Professor, University of Maine Cooperative Extension
Introduction
In November of 2007, Maine Maritime Academy and its Tidal Energy Device Evaluation Center (TEDEC) were granted a preliminary permit by the Federal Energy Regulatory Commission (FERC) for further, exclusive investigation of two sites (in Castine Harbor and the Narrows of the Bagaduce River), to determine suitability for generating electricity from tidal energy. TEDEC now has three years (from the date of preliminary permit) to assess environmental and other impacts of its proposed activities prior to seeking a permanent license for power generation as part of testing facilities. For more detailed information about TEDEC, see http://tedec.mma.edu/
The stated mission of TEDEC is to
TEDEC’s early work will be aimed at private and public sector collaboration in establishing tidal energy as a significant alternative energy source without significant environmental or other impacts.
For that collaboration to happen, officials at Maine Maritime Academy and TEDEC have chosen to engage stakeholders and the public to determine concerns and identify avenues of collaboration, in preparation for application for a full license from the Federal Energy Regulatory Commission in 2010/2011.
In order to increase the effectiveness of these engagement efforts, TEDEC requested assistance through Maine Solutions, a program of University of Maine Cooperative Extension (www.mainesolutions.org ). The role of Maine Solutions in this project is initially to assess community interest, and then, with stakeholder involvement, to establish a “working group” that will: · To summarize community concerns and interests identified during community assessment and April 30 community forum · To summarize the kind of information that is needed to respond to community concerns; · To suggest community resources (local, state, and beyond) that can assist in collecting that information · To create a declaration of cooperation that outlines roles and responsibilities of any collaborative efforts to collect, summarize and report that information · To facilitate two-way communication between the community and TEDEC This working group will be convened by State Senator Dennis Damon. In addition to the above purposes, this working group will identify initial and potential forms of collaboration, as the work of TEDEC goes forward. Although it will include representation from TEDEC and Maine Maritime Academy, it will be independent from these entities.
In February and early March of 2008, the coordinator of Maine Solutions, Ron Beard, conducted interviews concerning possible impacts and opportunities that the proposed tidal energy device evaluation center and its activities might bring to the environment and the community. The assessment included interviews with over thirty individuals and members of groups, including face to face conversations with: · Peter Vogell and David Unger, Selectmen, Castine · Sarah O’ Malley and Margery Read, Conservation Trust · Dale Abernethy, Town Manager, Castine · Mike Coughlin, Lee Wylie, Sue Hatch, Gil Tenney, Don Mordecai interested Castine citizens · Veronica Young, Marine Environmental Research Institute, Blue Hill · Jim Dow, Blue Hill Heritage Trust · Bente Hartmann, Bette Norris, David Wyman, Mike Mainen, Castine Harbor Committee · Nonny and John Ferriday, Bagaduce Watershed Association · Sarah Cox, Brooksville Harbormaster · Karen and Fred Motycka, marina owners, Penobscot · Ken Cline and Chris Peterson, faculty, College of the Atlantic
and phone conversations with: · Robin Alden, Penobscot East Resource Center · Robin Mass, Comprehensive Plan Committee · Jeff Romano and Jane Arbuckle, Maine Coast Heritage Trust · Jesse Leach, maineoysters@yahoo.com · Paul Venno, Harborside, Lobster Zone Council · Richard Parke, Lobster fisherman · Walter Foster, Lobster fisherman · Will Hopkins, Cobscook Fisheries Resource Center, Eastport · John Kerry and Jennifer Puser, Maine Office of Energy Independence and Security · Don Perkins, Gulf of Maine Research Institute · Bob Peacock, Harbor Pilot, MMA Graduate and Board member · Jay Clement, US Army Corps of Engineers, Augusta · Caren Plank, Owner of Sparks and Little Mollie Islands in Bagaduce
NOTE: Inclusion of these names in this assessment does not imply their endorsement of TEDEC or its proposed activities.
Each conversation followed a similar format, as shown by seven questions denoted in bold type below. Because the responses to the question about potential impacts (Question 3) were so varied, we have grouped those responses into the following categories of potential impact or concern:
Environmental Impacts · Concerns about marine life in general, spawning areas, habitat, seal pupping areas (at and above the Narrows -May and June is prime time) · Sites on Bagaduce are mapped as essential habitat for bald eagles by Maine Department of Inland Fisheries and Wildlife · Impact on marine plant life, including eel grass (note recent re-vegetation of up-river sites) · The Bagaduce is habitat for diverse shore and other bird populations: Greater and Lesser Yellowlegs, plovers, pipers, kingfisher, osprey · Bagaduce is incredibly rich wildlife and fisheries area (otter, harbor porpoise, seals, pilot whales, waterfowl, horseshoe crab, sea worms, stripers, eagles, pygmy alewives (fish ladder at Walker Pond- is it working?) · The Bagaduce is one of four Maine rivers where horseshoe crabs breed. What do we know about breeding sites, routes and distribution patterns? Do horseshoe crabs over-winter in deep spots in river, harbor? · Are there seasonal differences (summer to winter) in ecology, usage of area by fish and other critters · How will the test equipment affect water flow and currents? Will the turbulence attract fish and other species to tangle with gear underwater? Will fish or other species be cut up by whirling turbines? · Will any turbulence change patterns of erosion and deposition of sediments? · Does increased turbulence change how filter-feeders get food? · This is a great opportunity to see the harbor and Bagaduce as a system, not just physical characteristics… to achieve this systems view, the impact analysis needs to go beyond those elements called for by the FERC regulatory process · Will tidal energy devices have to be “painted” with toxic anti-fouling materials? Will there be any leaching of substances during construction or operation, and what effect would this have? · Will there be any slowing of current due to tidal energy devices, will this impact wetlands in the upper Bagaduce? · Are there both local (site specific) and systems (estuary/watershed) impacts?
Impacts on Navigation, Boating and Moorings · Potential for interference with navigation, boat passage, moorings (Will there also be a security perimeter around equipment? How will they be marked? Will these sites show up on charts? How will boats and others be notified something is in the water?) · Will the test sites affect current moorings for boats or prevent expansion of moorings where town might like to expand? · There is a navigational channel recognized by the Coast Guard · Effect on navigation in main harbor and local coves (Smith’s and Hatch)… “the ledges are hungry in these parts” · The Narrows are very narrow… one lobsterman fishes above them (off Young’s Island, Mills Point) and needs to get through that channel) · How might a freeze-over affect the tidal energy equipment? · How will the facilities be sited to avoid damage by ice movement (as is the case for many docks/floats that have to be hauled out) · Will installation phase and operations phase of tidal energy facilities have any direct or indirect affects on navigation? · There is a cumulative effect of increased use and development of these shared public resources—tidal energy, aquaculture, kayaking, pleasure boating, fishing, etc
Impacts on Fishing Interests · Will the sites in any way disrupt current or historical fishing practices? · Curiosity expressed about impact on lobster, lobster fishing, crabs, scallops (historical fishery), mackerel, sea urchins · Will there be vertical lines that will endanger fish and marine mammals? · How will they keep equipment from fouling… lots of rockweed, tree branches and other flotsam comes down river… Screens would quickly foul · Will traps, trap-lines get caught on any cables on bottom or suspended · Overboard discharge has limited clam harvests to depuration digging… if those sources of pollution are cleaned up, will tidal energy devices likely to impact clam fishery? · Will siting of equipment and cables create mini-no-drag zones that will serve as interesting study sites? (in effect very small marine protected areas?)
Impacts on other current economic interests · Will TEDEC bring jobs and let contracts to local people/companies resulting from this activity; is there an economic multiplier effect for Castine and region? · Will kayaking, cruiseboats be affected? · Impacts on electrical rates? Will the local community benefit in some way? · We may learn more about how tides can generate electricity, for benefit of Maine and nation · What will we learn about the economics of tidal energy at various scales? · What direct/indirect impacts will installation and operation of these facilities have on tourism and local boating, marina use, etc?
Impacts on community, including adjacent land owners and other residents · The Bagaduce estuary has very high scenic values for adjacent land parcels… what objections will there be from landowners? · What will the various testing facilities and sites look like? · Aesthetics (visual impacts) will be of concern during initial installation and operation of test areas, and of getting power from test turbines to land and hooking into power lines · As we have seen with development of wind farms, some of the concerns are subjective, about the appearance of facilities… we should expect similar concerns with tidal energy · Noise associated with installation, turbines and maintenance · If access to the grid from tidal energy devices is to be over town or private land, how will TEDEC gain permissions? · Will eminent domain be used to site current or future facilities? · What will “barge” look like when used to replace underwater equipment, turbines? · Any change is a change, increased use of the “commons” and traditional users may be impacted · There is a larger concern that Maine, as other rural areas, is being asked to serve as source of energy for the larger grid, where there are no incentives to conserve… · Will local towns or businesses receive any reduced power rates in return for · Will any kind of electrolysis impact other underwater equipment? Will there be any impacts due to frequency of energy generated? What happens when cables “leak” electricity? · Is there danger of Electromagnetic Fields from electrical lines · Where, exactly, will test equipment go, or is the next two years of study to determine optimal locations?
Impacts on community facilities · What are the shore-side impacts from all initial installation, staging areas and then from on-going operations? · What impacts will the proposed testing facility have on town facilities (including water and sewer), services, zoning, noise, pollution, traffic, parking (town currently doing a study) · Will Central Maine Power need to upgrade the capacity of its lines to accommodate the anticipated electrical loads?
Concerns about Permitting Process · FERC process not geared to small sites, so on the surface, the application process may make it seem grander in scale and impact that is actual situation · Since this is among first of many applications to follow in Maine, we need top notch science applied to determine baseline and impacts (it is not enough that undergraduate students and their teachers, good as they are, might be involved) · We need peer review of all science protocols and findings, final impact analysis should be done by those without vested interests—those who do the research should be neither pro nor con as far as TEDEC or tidal energy is concerned · What is the largest conceivable equipment that could be tested…or will all equipment be scale models? · Will different generating equipment have different impacts and how to know in advance? · Is this the first step in eventually licensing these sites for commercial power generation? · Is this a permanent facility designed to test tidal equipment well into the future, or just testing these sites to determine potential for electrical generation by tidal flow? · What is the length of time the FERC license is good for? Can the initial purpose and technology “morph” into something else without oversight, and further licensing? What size (how large?) operation/facilities would be permitted under the application? Are there limits to growth of these operations? · How much power will be generated, and who benefits from this use of a public resource? What happens to the money from sales of electricity? · Is FERC “fast tracking” this application, and if so, how does that impact the ability of local people and others to comment? · In addition to FERC, the Army Corps of Engineers needs to review and grant permits for some of TEDEC facilities… they have concurrent reviews with all other federal and state agencies… how will local people be made aware of these and make input to these reviews? · Will state just decide that we are a prime power generating location and override local ordinances and concerns, like they did with aquaculture? · How will the community, state and federal government adapt policies that “learn from” the experience of TEDEC and others developing new technologies?
Concerns about TEDEC as an Organization · Why here, why now? What is the rationale? · How did TEDEC come into being, and who benefits directly from its existence? What are the roles and benefits to the non-MMA partners? Who holds the power to make decisions, how are MMA trustees involved? What are the by-laws of TEDEC? Who are the employees and what are their salaries? · Where does/will funding come from? If there are federal funds, will they come directly to TEDEC, to MMA, or to University of Maine? · Lack of clear picture of what is being proposed (some say that different audiences get different presentations about what is being proposed) · How will local people continue to have a role in monitoring the project and providing input? · Where did the seed of this TEDEC idea start and how did it become a full proposal? · What is the business model and what will happen to any “profit”? · If supported by public funds, but some research is proprietary, how transparent and open will TEDEC be with both the initial environmental impact and studies of tidal energy generating devices? How can the great bulk of information be shared so society benefits? Or will this be more like a private research and development initiative? · Suggest that TEDEC take lessons from LURC review of Plum Creek proposal for Moosehead Lake… virtually everything that the applicants submitted was easily accessible through the LURC website.
