Frankfort keps restrictive wind ordinance NOv 5, 2014

Frankfort voters reject referendum that would have repealed restrictive wind ordinance

FRANKFORT — Frankfort residents voted Tuesday by 138 votes to retain their existing wind energy ordinance rather than repealing it and adopting the state's model wind ordinance. The tally was 224 in favor of repeal to 362 opposed.

The vote prevents the Waldo Community Wind project, a planned six-turbine, 18-megawatt wind power project proposed by Portsmouth, N.H.- based Eolian Renewable Energy LLC, from going forward. According to Eolian, the project would have delivered clean, emission-free power to about 6,500 homes across Maine and New England.

Frankfort had no municipal land-use ordinances before its wind energy ordinance was adopted in 2011. According to previously published reports, that ordinance came in response to the initial proposal by Eolian to erect four to six turbines on Mount Waldo.

Concerned about negative impacts on abutting properties and property owners, residents approved a 180-day moratorium in March 2011 and established a five-member committee to draft the wind energy-specific ordinance. The resulting ordinance included one-mile setbacks from abutting property lines and restrictive noise regulations that amounted to a ban on industrial-scale wind turbines. That ordinance was passed in December 2011 by only 22 votes.

The landowners of the proposed wind farm site on Mount Waldo then brought a lawsuit against the town over the ordinance. At the town meeting in March 2013, town members voted 178-131 against a consent order that would have settled the lawsuit by allowing the wind project to go forward. The item was placed on the warrant in exchange for the plaintiffs agreeing to drop monetary damage claims regardless of the outcome of the vote.

Citizens petitioned in August to bring the question to a vote, and two of the three selectmen supported placing it on the November ballot. A public hearing was held in October, which about 35 people attended, according to Frankfort selectmen. The town also held a hearing on tax-related questions about the project.

If it had gone forward, the Waldo County Wind project would have been the largest taxpayer in the town. Jack Kenworthy, CEO of Eolian, wrote in a guest column in this paper that, according to a recent analysis, "The first-year tax amount will be well above $300,000 and then the annual amounts will increase ... [which could] reduce the local mill rate by between 25 percent and 35 percent for the first three years and then by about 10 percent each year thereafter."

Eolian was also offering a $100,000 benefit package to the town that includes funds for local scholarships, support for both Frankfort fire departments, aid for several local charities and an energy rebate fund available to all Frankfort residents. The company conducted a town-wide survey and canvassed door to door for public comment to determine the most popular items to include.

However, Selectman Joe Watson said Monday, Nov. 3, that he was uncertain whether the project would indeed benefit Frankfort.

"I have no idea," he said, "They make it sound good, but we don't know. Things could change. No one really knows the answers right now."

Kenworthy said Mount Waldo is an ideal site for a small utility-scale wind energy project because of its outstanding wind resource and sufficient clearings and because there are already communication towers and electrical lines on the mountain.

Mount Waldo has a history of industrial use and grand but foiled plans. A quarry was in operation there, owned by Mt. Waldo Granite Works from 1853 to 1916, and then by Mt. Waldo Granite Corp. from 1930 to 1969, according to the Penobscot Marine Museum website.

After that company went bankrupt, the Small Business Administration loaned Buster Shapiro of Braintree, Mass. money to purchase the property. His plans to build a multimillion-dollar amusement park on the site and name it "Mohammed's Mountain," also fell through.¹

Kidder Point History. August 1974, Delta Chemical, sulfuric acid plant acid fail causes shipwreck.

Excerpt about the acid plant and its  shipwreck causing August 1974 acid smog spill on kidder point from the BAR Railroad v Fernview, vs Delta chemical etc  lawsuit  in the 1970s

EXCERPT
22. The Delta facility at Searsport consists of two separate sulfuric acid manufacturing plants, plant # 1 and plant # 2, each of which produces sulfuric acid through the "contact" process.

23. In the final stage of the contact manufacturing process sulfur trioxide ("SO3"), a colorless gas which bears a slightly pungent odor, is pumped into the bottom of an "absorber." The absorber consists of a tower packed with rashig rings which increase the contact surfaces within the tower. As SO3 enters the bottom of the absorber and is forced upward, a strong solution of sulfuric acid, a liquid, enters at the top of the absorbing tower and trickles downward. The SO3 mixes with water in the acid solution to form additional sulfuric acid, which is drawn off and stored as the product of the plant.

24. The SO3 which enters the absorber is only about 98% pure and contains residues of sulfur dioxide ("SO2"), a colorless yet extremely pungent gas which smells

[455 F.Supp. 1052]

like burning sulfur,21 and oxygen, and nitrogen, both odorless and colorless gasses.

25. Under standard operating conditions a certain amount of SO3 does not mix with the sulfuric acid solution in the absorber, but instead passes through the absorbing tower and out the stack into the atmosphere. In addition to the SO3, the residues of SO2, oxygen, and nitrogen contained in the SO3 normally pass through the absorbing tower and are emitted from the stack.22

26. Though colorless itself, SO3, when emitted from the stack, combines with moisture in the atmosphere to form sulfuric acid mist, or, as it is known more commonly, acid mist. Acid mist is visible, appears white like ordinary water vapor, and is heavier than air. Acid mist is slow to disperse under foggy or humid conditions because fog and humidity tend to entrap it. Fog and humidity also hamper the dispersion of SO2 which, like acid mist, is heavier than air.

27. The optimum concentration of the sulfuric acid solution pumped into the top of the absorbing tower is 98.5% to 98.8% sulfuric acid by weight. The remainder is water. If the strength of the acid solution exceeds 98.8%, the efficiency of the conversion of SO3 into sulfuric acid decreases and the amount of SO3 emissions passing through the absorbing tower and out the stack correspondingly increases. The other emissions, SO2, oxygen and nitrogen, remain unchanged and continue to pass out the stack.

28. The concentration of the sulfuric acid solution entering the absorbing tower is recorded on a graph by a "98% acid recorder."23 The 98% acid recorder thus enables plant operators to monitor the strength of acid solution pumped to the absorber. On the basis of data yielded by the recorder, plant operators increase or decrease the strength of the sulfuric acid solution as conditions may warrant. The sulfuric acid solution must be adjusted continually in order to maintain the proper acid strength.

29. The normal operating life of a 98% acid recorder varies from ten to twenty years. The recorder in use in Delta plant # 2 during all times material to the present litigation was eighteen years old. In the week preceding August 21, 1974, the recorder for plant # 2 was repaired or recalibrated on at least five occasions.24 Prior to August 21, Delta had available in stock a new 98% acid recorder with which it could have replaced the recorder for plant # 2.
30. Delta plant # 2 was in continuous operation on August 20-21, 1974 until 0710, August 21.

31. At approximately 0030 on August 21 Randall Blake, the "A" operator for plant # 2 observed that the plant's 98% acid recorder had begun to malfunction.25 The recorder continued to malfunction throughout the early morning hours of August 21 and ceased to measure accurately the concentration of the sulfuric acid solution which entered the absorber.26 Without benefit of the information provided by a fully operational recorder, the plant in effect was "flying blind" from approximately 0030-0100 onward.27 However, at no time after Delta personnel had become aware of the malfunction were instrument technicians called in to repair the recorder.

32. As a result of the recorder malfunction, the operators of plant # 2 permitted the strength of the sulfuric acid solution which was pumped into the absorber to creep above the optimum concentration of 98.5% to 98.8% sulfuric acid.
Increased acid strength caused excessive amounts of SO3 to escape from plant # 2 during the early morning,28 along with the residual emissions of SO2, oxygen, and nitrogen. The plant continued to produce excessive emissions until it was shut down due to these emissions around 0710.29 The plant was not equipped with instrumentation capable of measuring the volume of emissions which passed through the stack during the period. Hence, it cannot be determined precisely how much gas was emitted on August 21.30

33. Delta personnel had known of the repeated malfunctions of the 98% acid recorder for plant # 2 which had occurred in the days immediately preceding August 21 and had learned of the latest recorder malfunction approximately six and one-half hours before the plant was ordered shut down and approximately seven hours prior to the FERNVIEW's collision with the BAR dock.

34. Although both Bennett and Harry L. Burns, the shift supervisor who succeeded Bennett at 0630 on August 21, possessed the authority to shut the plant down because of excessive emissions, neither did so.

35. Upon entering the atmosphere, the excessive SO3 emissions produced by plant # 2 reacted with moisture in the air to form clouds of acid mist. Some of this acid mist, along with the other emissions normally produced by the plant (SO2, oxygen and nitrogen), were carried by winds southwesterly to the BAR dock. The acid mist to some degree contributed to and made more dense the preexisting natural fog which the FERNVIEW encountered during its attempt to land at the dock.31

Rockport Harbor, according to the Maine Coastal Pilot

(443) Rockport Harbor, on the west side of West Penobscot Bay about 4 miles northward of Rockland Harbor, is a good anchorage for vessels of any size, sheltered from all but southerly winds, and is easy of access. The harbor is about 0.7 mile wide at the entrance between Indian Island and the western shore, and gradually narrows to the head.

(444) Rockport is a town at the head of the harbor at the entrance to Goose River.

 Prominent features 
(446) Lowell Rock Light 2 (44°09.8'N., 69°03.6'W.), 25 feet above the water, is shown from a spindle with a triangular red daymark on the south end of Lowell Rock. A fairway bell buoy 0.4 mile southeast of the light marks the entrance to the harbor. A clock tower at the head of the harbor is conspicuous. Beauchamp Point,the eastern point of Rockport Harbor north of Indian Island, is prominent.

(447) 
 Channel 
(448) The entrance is deep and clear with the exception of Porterfield Ledge in the middle of the entrance. The depths in the channel range from over 50 feet in the entrance to 8.3 feet at the head. Passage is sometimes made by local small craft at high water across the ledge between Indian Island and Beauchamp Point.

(449) 
 Anchorages 
(450) Vessels can anchor anywhere between the entrance and a point 1 mile southward of the head, in depths of 42 to 63 feet, soft bottom. Small vessels and motorboats can find anchorage nearer the head.

(451) 
 No-Discharge Zone 
(452) The State of Maine, with the approval of the Environmental Protection Agency, has established a No-Discharge Zone (NDZ) in the coastal waters of Camden, Rockport, Rockland, and portions of Owls Head (see chart 13307).

(453) Within the NDZ, discharge of sewage, whether treated or untreated, from all vessels is prohibited. Outside the NDZ, discharge of sewage is regulated by 40 CFR 140 (see chapter 2).

(454) 
 Dangers 
(455) Porterfield Ledge, in the middle of the entrance to Rockport Harbor, uncovers several feet at low water; a daybeacon is on the ledge. Indian Island, on the eastern side of the entrance, is grassy and marked at its south end by an abandoned lighthouse. An unmarked fish weir is on the west side of the harbor, about 0.3 mile southward of the entrance to Goose River.

(456) Seal Ledge, uncovered at low water, on the east side of the harbor about 0.7 mile northward of the light, is marked by a daybeacon.

(457) 
 Routes 
(458) Vessels can enter Rockport Harbor on either side of Porterfield Ledge Daybeacon, giving the daybeacon a berth of at least 150 yards. When in the harbor stand northward in midharbor until 0.3 mile from the head, then slightly favor the eastern side.

(459) 
 Supplies 
(460) Gasoline, diesel fuel, ice, provisions, and some marine supplies can be obtained in Rockport.

Depths of 3 feet are reported alongside the float; water is available. The Rockport Yacht Club, close westward, has a float landing with 3 feet reported alongside. There are a number of private wharves in the harbor.

(463) A boatyard, close eastward of the public landing, has a 12-ton mobile hoist and facilities for open or covered winter storage. Depths of 8 to 10 feet are reported alongside the floats. Hull and engine repairs can be made, and gasoline, diesel fuel, water, ice, electricity, marine supplies, and transient moorings are available. The yard builds boats up to 45 feet long.

(464) A municipal marina park is on the west side of the harbor, about 120 yards west of the boatyard. Transient berths, with depths of 3 to 8 feet reported alongside the floats, are available.

(468) Deadman Point is about 0.4 mile northeast of Indian Island. Hog Cove, on the north side of Deadman Point, has two private piers with float landings. Hog Cove Ledge extends about 0.4 mile above Deadman Point and forms the eastern side of the cove. Goose Rock is a bare ledge about 0.2 mile north of Hog Cove Ledge. A 12-foot spot 0.4 mile northeast of Deadman Point is marked on the east side by a buoy.

(469) The Graves, about 1 mile offshore, midway between the entrance to Rockport and Camden Harbors, is a ledge showing bare rocky heads at high water and a large area that uncovers at low water. A lighted gong buoy is just eastward of The Graves.
