Regulation of Access to Oil Pipelines 777
REGULATION OF ACCESS TO OIL PIPELINES 777 THE NATIONAL ENERGY BOARD: REGULATION OF ACCESS TO OIL PIPELINES JENNIFER HOCKING* In the past few years, a number of long-distance oil pipelines have been proposed in Canada — Northern Gateway, the Trans Mountain Expansion, Keystone, and the Energy East Project. This article describes the criteria used by the National Energy Board in approving the allocation of capacity in oil pipelines to firm service contracts while requiring that a reasonable percentage of capacity is allocated for uncommitted volumes (common carriage). It explains the economic theory related to regulation of access to major oil pipelines. It reviews and analyzes relevant NEB decisions, which show that the NEB supports well- functioning competitive markets, but will exercise its discretion to resolve complaints where markets are not functioning properly. The article also explains the economic significance of the proposed long-distance oil pipelines to Canada and Alberta despite the current low price of crude oil. The article concludes with recommendations for a written NEB policy regarding access to capacity in oil pipelines. TABLE OF CONTENTS I.

Time and Tides in the Gulf of Maine a Dockside Dialogue Between Two Old Friends
1 Time and Tides in the Gulf of Maine A dockside dialogue between two old friends by David A. Brooks It's impossible to visit Maine's coast and not notice the tides. The twice-daily rise and fall of sea level never fails to impress, especially downeast, toward the Canadian border, where the tidal range can exceed twenty feet. Proceeding northeastward into the Bay of Fundy, the range grows steadily larger, until at the head of the bay, "moon" tides of greater than fifty feet can leave ships wallowing in the mud, awaiting the water's return. My dockside companion, nodding impatiently, interrupts: Yes, yes, but why is this so? Why are the tides so large along the Maine coast, and why does the tidal range increase so dramatically northeastward? Well, my friend, before we address these important questions, we should review some basic facts about the tides. Here, let me sketch a few things that will remind you about our place in the sky. A quiet rumble, as if a dark cloud had suddenly passed overhead. Didn’t expect a physics lesson on this beautiful day. 2 The only physics needed, my friend, you learned as a child, so not to worry. The sketch is a top view, looking down on the earth’s north pole. You see the moon in its monthly orbit, moving in the same direction as the earth’s rotation. And while this is going on, the earth and moon together orbit the distant sun once a year, in about twelve months, right? Got it skippah. -

Ecoregions of New England Forested Land Cover, Nutrient-Poor Frigid and Cryic Soils (Mostly Spodosols), and Numerous High-Gradient Streams and Glacial Lakes

It is a relatively sparsely populated region compared to adjacent regions, and is characterized by hills and mountains, a mostly Ecoregions of New England forested land cover, nutrient-poor frigid and cryic soils (mostly Spodosols), and numerous high-gradient streams and glacial lakes. Forest vegetation is somewhat transitional between the boreal regions to the north in Canada and the broadleaf deciduous forests to the south. Typical forest types include northern hardwoods (maple-beech-birch), northern hardwoods/spruce, and northeastern spruce-fir forests. Recreation, tourism, and forestry are primary land uses. Farm-to-forest conversion began in the 19th century and continues today.

A Review of Ice and Tide Observations in the Bay of Fundy

Mossman2 127 Harding Avenue, Amherst, Nova Scotia B4H 2A8, Canada departm ent of Physics, Engineering and Geoscience, Mount Allison University, 67 York Street, Sackville, New Brunswick E4L 1E6, Canada Date Received April 27, 1998 Date Accepted December 15,1998 Vigorous quasi-equilibrium conditions characterize interactions between land and sea in macrotidal regions. Ephemeral on the scale of geologic time, estuaries around the Bay of Fundy progressively infill with sediments as eustatic sea level rises, forcing fringing salt marshes to form and reform at successively higher levels. Although closely linked to a regime of tides with large amplitude and strong tidal currents, salt marshes near the Bay of Fundy rarely experience overflow. Built up to a level about 1.2 m lower than the highest astronomical tide, only very large tides are able to cover the marshes with a significant depth of water. Peak tides arrive in sets at periods of 7 months, 4.53 years and 18.03 years. Consequently, for months on end, no tidal flooding of the marshes occurs. Most salt marshes are raised to the level of the average tide of the 18-year cycle. The number of tides that can exceed a certain elevation in any given year depends on whether the three main tide-generating factors peak at the same time. Marigrams constructed for the Shubenacadie and Cornwallis river estuaries, Nova Scotia, illustrate how the estuarine tidal wave is reshaped over its course, to form bores, and varies in its sediment-carrying and erosional capacity as a result of changing water-surface gradients. -

The Lady Crab (Ovalipes ocellatus), mainly found south of Cape Cod and in the southern Gulf of St. Lawrence, is reported from an ocean beach on the north shore of Massachusetts Bay (42°28'60"N, 70°46'20"W) in the Gulf of Maine.

CROIX RIVER UPDATE Joint Tribal Council of the Passamaquoddy Tribe passes St. Croix River Alewife Resolution Citing the vital linkages that sea-run alewives create in the food chain of the St. Croix River, Passamaquoddy Bay and the Bay of Fundy, members of the Joint Tribal Council of the Passamaquoddy Tribe voted unanimously to pass a resolution that calls for reopening the St. Croix Rivers for alewives. !e resolution states that sea-run alewife are a vital link in the food chain of the St. Croix River that sustained the Passamaquoddy for thousands of years, “without which we may not have survived.” !e Joint Tribal Council resolution supports the June 14, 2012 Passamaquoddy Chief’s Declaration of a State of Emergency within the St. Croix River, and calls for overturning Maine’s 1995 law that blocks alewives from the St. Croix. In early June 2012 members of the Schoodic Riverkeepers advanced the Passamaquoddy river restoration e"ort with a 100-mile sacred run up the St. Croix River, a run that mirrored the annual trek of native alewives. !e route extended from Pleasant Point, near Eastport, to Mud Lake Stream, a 4,000-year-old ancestral #shing site for the Passamaquoddy at the head of Spednic Lake.

Keystone XL Pipeline: Overview and Recent Developments
Keystone XL Pipeline: Overview and Recent Developments Updated April 1, 2015 Congressional Research Service https://crsreports.congress.gov R43787 Keystone XL Pipeline: Overview and Recent Developments Summary TransCanada’s proposed Keystone XL Pipeline would transport oil sands crude from Canada and shale oil produced in North Dakota and Montana to a market hub in Nebraska for further delivery to Gulf Coast refineries. The pipeline would consist of 875 miles of 36-inch pipe with the capacity to transport 830,000 barrels per day. Because it would cross the Canadian-U.S. border, Keystone XL requires a Presidential Permit from the State Department based on a determination that the pipeline would “serve the national interest.” To make its national interest determination (NID), the department considers potential effects on energy security; environmental and cultural resources; the economy; foreign policy, and other factors. Effects on environmental and cultural resources are determined by preparing an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA). The NID process also provides for public comment and requires the State Department to consult with specific federal agencies. TransCanada originally applied for a Presidential Permit for the Keystone XL Pipeline in 2008. Since then various issues have affected the completion of both the NEPA and NID processes for the project. In particular, during the NID process for the 2008 application, concerns over environmental impacts in the Sand Hills of Nebraska led the state to enact new requirements that would change the pipeline route. Facing a 60-day decision deadline imposed by Congress, the State Department denied the 2008 permit application on the grounds that it lacked information about the new Nebraska route.
