Eighteen months after Senators John McCain (R-AZ) and Harry Reid (D-NV) joined forces to undermine the National Park Service’s Grand Canyon air tour management plan just before it was set to go into effect, the Federal Aviation Administration apparently feels that the discounted per-flight fee for quiet aircraft is not incentive enough to encourage the air tour industry to invest in new-generation planes. Rather, the FAA has decided that the best way to do so is to allow 1721 additional flights to the annual parade of planes piercing the skies over the Grand Canyon, so long as these new flights utilize “quiet” aircraft.

“The so-called quiet technology is not quiet,” said Sandy Bahr, director of the Sierra Club’s Grand Canyon Chapter. “It’s less noisy, but it’s not quiet.” Flagstaff resident Jim McCarthy, who did a master’s thesis at Arizona State University on noise pollution in the Grand Canyon, said air tour companies are “gaming the park.” Because the quiet technology is defined by noise per seat, aircraft can be noisier as long as they hold more people, he said. “It can be completely counterproductive.” (above image is the view from an air tour)

A park spokesperson notes that the additional flights only add about 3% to the flights already occurring; at peak times, planes take off every 90 seconds, heading for the two most popular air tour corridors.  As with snowmobiles in Yellowstone, the annual cap on allowed flights is far higher than the number of flights that have been occurring in recent years: the FAA authorized about 90,000 flights in 2012, the most recent year for which numbers were available, though only (!) 55,185 commercial air tours were actually flown that year.

After nearly five years of floating offshore wind farm planning off the coast of Maine, a project in Oregon may leapfrog those efforts.  An initial go-ahead from federal ocean regulators marks the starting line for a pilot project off Coos Bay, which will need to clear several more regulatory and financial hurdles before being built.  

Perhaps optimistically, Principle Power (the developer) is holding a target date of 2017 to have its initial five turbines operational.  These will be huge, 6MW, 600-foot turbines, similar in design to a model that’s already being tested in the water in Portugal.  The project is expected to cost $200 million, which would build around 100MW of capacity on land, as compared to the 30MW this pilot project will construct; Principle Power expects that steadier, stronger offshore winds will let these turbines operate at a higher capacity factor than onshore projects, partially making up that difference. Of course, experimental pilot projects are always far more expensive than later, full-scale build-outs; still, the financial feasibility of projects like this is a work in progress.

Last fall, Dominion Virginia Power won the first federal lease for developing wind power off the coast of Virginia.  As with all offshore energy and Naval activity on the east coast, one of the first environmental concerns to be raised was what measures would be taken to minimize impact on the critically endangered North Atlantic Right whale. While their population has been more or less steadily rising since 1990, with only about 400 individuals, they remain vulnerable to any negative impacts, from ship strikes to increased stress levels, which may reduce reproductive rates and success. (See NOAA’s most recent stock assessment report for details; it notes lower reproductive rates than other Right whale stocks, and concludes that the population will be negatively affected if it loses more than 0.9 whales per year to human impact.)

With all this in mind, Dominion Virginia Power’s first commitments to the Virginia Offshore Wind Development Authority fell far short of what many had hoped.  The company agreed to limit installation activity of test platforms (meteorological towers and preliminary test turbines) during the period when whales are most apt to be migrating past the Virginia coast, but made no such commitments about later, and much more extensive, pile-driving for hundreds of turbines in the eventual wind farm.

“We’re happy to talk” with environmental groups, said Mary C. Doswell, Dominion Resources Inc.’s senior vice president for alternative energy solutions, though she noted, “we can’t overlook the costs of compliance.”

The company said they’d minimize their first-phase activities from late November to late March.  The whales spend the summers in a large area off the coast of New England and the Canadian Maritimes, and concentrate at birthing grounds off the coast of northern Florida in winter. NOAA maintains a reduced speed zone along the mid-Atlantic coast, to protect migrating Right whales, from Nov.1 to April 30, close to two months longer than the company set aside as their cautionary season; even the speed restriction is seen by some as a potential obstacle to offshore wind data collection.

UPDATE: See also this article from last fall, which suggests that Dominion plans only to erect a 2-turbine test platform, with full-scae development of 200 or more turbines on hold until costs come down for offshore wind construction.  Some wind advocates suggest that Dominion, which has fought renewable energy initiatives in the state, secured the lease largely to prevent others from developing a large offshore capacity.

The state Public Service Board has initiated a public process for re-examining the noise standards used at wind and natural gas energy facilities in Vermont.  Geoff Commons, the PSB’s public advocate, notes that neighbor complaints from wind projects operating in compliance with a 45dB standard are part of the driver for this review.

“Even with these restrictions placed on several recently constructed facilities, the board has received complaints regarding sounds produced by the operation of some facilities. These complaints have raised questions about whether the limitations that the board has previously adopted are adequate,” the PSB stated in December.  “As a result, the board has determined that it is appropriate to commence a general investigation into the issue of appropriate sound standards for facilities that are subject to the board’s jurisdiction.”

The PSB has established a website to track this process.  A pre-hearing conference was held on January 8, and based on discussions there, a scoping document outlining initial ideas about procedures and key questions for the process have were released on January 29, and can be downloaded here.  Public comments are being accepted through March 3, after which the final scope of the process will be determined, followed by a series of public workshops to address specific issues.  The outcome of this process will be a determination as to whether a new set of binding sound-related standards is needed; if so, that will occur during a separate formal process.

From my first reading of the preliminary scoping document, it appears that the focus may be strongly oriented toward health effects, and the standard effort to determine “state of the art” scientific information; the initial list of questions doesn’t appear to consider quality of life impacts.  However, the final scope may change, based on comments during this scoping phase.
