Terminal Pollution

Terminal Pollution
Do the voters from the town of Bar Harbor, on the west side of Frenchman Bay, want a cruise ship berthing facility for large cruise ships at the old Ferry Terminal property adjacent to their downtown? This town includes voters from Bar Harbor, Hulls Cove, and Town Hill.

Of the number of environmental factors that need to be investigated regarding the terminal berthing for cruise ships, one in particular, and most important, is air pollution. How do sulfur dioxide and other toxic chemicals emitted from burning diesel adversely impact residents of Bar Harbor and those in towns surrounding Frenchman Bay, which include Gouldsboro, Winter Harbor, Sorrento, Sullivan, Hancock, Lamoine, and Trenton? How are visiting tourists to Bar Harbor and Acadia National Park affected by these noxious fumes? Here are some researched and documented answers.
Sulfur Dioxide Emissions from Large Diesel Engines
Keep in mind four established facts that compare diesel engine emissions from land vehicles and cruise ships:
Eighteen wheelers, dump trucks, and buses—emit 15 parts per million (ppm) of sulfur dioxide into the atmosphere while idling;1 whereas, cruise ships release 1000 ppm of sulfur dioxide at idle which works out to be 66 times more sulfur dioxide than what those diesel vehicles emit.
While idling, 18 wheelers burn 1 gallon of diesel fuel per hour. One large cruise ship burns 320 gallons of diesel fuel per hour while idling in port to produce electricity.

The Environmental Protection Agency (EPA) recommends laws that restrict the idling of large diesel trucks and buses to no more than 5 minutes because of the Group 1 carcinogenic rating that diesel has when it is burned.2 All of California as well as many cities and towns across the United States now have put this law into effect.2
In addition, Bar Harbor code # 194-38,3 which was enacted on 17 June 1997, states that no motor vehicle is allowed to idle more than 5 minutes anywhere downtown. This code not only includes diesel vehicles but also cleaner gasoline-powered vehicles also.

Cruise ShipsElectrical Needs That Affect Air Pollution
The electrical demands of cruise ships is also critical to understanding how they contribute to air pollution. When a large cruise ship is tied up to a dock, or berthed, the ship needs to generate 13 megawatts (MW) of electricity4 for thousands of people for its 10-hour visit.4 Used only seasonally, this tremendous amount of power is too demanding to plug into the towns electrical grid, it simply is not feasible. It costs $10 million per berth to install the electrical infrastructure required. A ships electricity is used for lights, internal power systems, and the desalination of ocean water to produce over 150,000 gallons per day of fresh water. For an average ship holding 3,000 people, this figure amounts to over 1 million
gallons per week.5
To produce their electrical needs, two large cruise ships berthed at the ferry terminal for their 10-hour visit will use 640 gallons (320 each) per hour and will emit 66 times the sulfur fumes that road vehicles emit per hour. The sulfur dioxide emissions from two ships are the same as the sulfur dioxide emissions from 42,624 18 wheelers at idle ( 640 X 66 = 42,624) for 10 hours. This violates Bar Harbor’s adopted downtown idling code by 5,114,880 times.

Impact of Toxic Chemicals from Diesel Exhaust on Health
Further, according to the Michigan Department of Licensing and Regulatory Affairs, Diesel Exhaust Gases says : “The toxic chemicals of most concern in diesel exhaust are the oxides of nitrogen (nitric oxide, nitrogen dioxide), sulfur dioxide, aldehydes, primarily formaldehyde, acetaldehyde and acrolein, and various hydrocarbons particles. . . . Prolonged exposure to diesel exhaust can increase the risk of cardiovascular, cardiopulmonary, and respiratory diseases, including lung cancer. In June 2012, the International Agency for Cancer Research (IARC) classified diesel exhaust, including diesel particulate matter, as a known human carcinogen (Group 1).”6
“Sulphur dioxide (SO2) is irritating to the eyes, throat, and respiratory tract. Short-term overexposure causes inflammation and irritation, resulting in burning of the eyes, coughing, difficulty in breathing, and a feeling of chest tightness. Asthmatic individuals are especially sensitive to SO2 and may respond to concentrations as low as 0.2-0.5 [parts per million] ppm. Prolonged or repeated exposure to low concentrations (1-5 ppm) may be dangerous for persons with pre-existing heart and lung diseases. Health effects are documented at various concentrations by different researchers and organizations. A sampling of health effects that sulfur dioxide fumes have on mucous membranes in healthy individuals are outlined in the following list.”7
1-5 ppm: Threshold for respiratory response in healthy individuals on exercise or deep breathing
3-5 ppm: Sulfur dioxide gas is easily noticeable. Decreased lung function at rest and increased airway resistance
5 ppm: Increased airway resistance
6 ppm: Immediate irritation of eyes, nose, and throat
10 ppm: Worsening irritation of eyes, nose, and throat
10-15 ppm: Threshold of toxicity for prolonged exposure
20+ ppm: Paralysis or death occurs after extended exposure
150 ppm: Maximum concentration that can be withstood for a few minutes by healthy individuals
When molecules of sulfur dioxide (SO2) are inhaled, they turn into sulfuric acid (H2SO4), which is battery acid. When nitrogen dioxide (NO2) is inhaled, it turns into nitric acid (HNO3), which is the nasty component in acid rain and smog. If it comes in contact with the ocean it acidifies.
If large cruise ships are berthed at the proposed 121 Eden Street terminal site, there will be times when the diesel exhaust from these berthed cruise ships will be blown on a west, northwest wind across the land into downtown Bar Harbor as a fumigating plume. Sometimes the exhaust will travel on an easterly sea breeze right at Paradise Hill, which would be level with the smokestacks a quarter mile away and continue into Hulls Cove and then into Acadia National Park and beyond. The health effects from the fumes of these cruise ships can be measured 200 miles inland from shipping areas.
Ports around the world show high rates of lung cancer and heart disease. In Europe, 60,000 deaths from diesel are attributed to ships burning diesel and 12,000 of them are from sulfur dioxide inhalation.8 (see pg 10)
After reading this documented research, come to your own thoughtful and rational conclusions on how close you want to live to high concentrations of diesel fumes.

p. 42.

A. Five-minute limitation. No person may cause or allow a motor vehicle to idle for more than five consecutive minutes while that vehicle is parked in any of the downtown areas during the time from May 1 to Columbus Day.

B. Exceptions. The limitation set forth in the preceding subsection shall not apply to:
(1) Fire trucks, police cars, ambulances and other emergency vehicles while responding to an emergency call.
(2) Utility vehicles, including contractor's equipment, while engaged in the construction, maintenance or repair of utility facilities.
(3) Motor vehicles idling while in a traffic lane, as the result of congested traffic conditions beyond the driver's control (traffic jams).
(4) Refrigeration units of delivery vehicles.

C. Prima facie evidence. The fact that a parked motor vehicle is idling in violation of this section shall be prima facie evidence that the unlawful idling was caused or allowed by the person in whose name that vehicle is registered.
