LIVERMORE FALLS – Selectmen voted Monday to put a building they declared dangerous in December out to bid for demolition.

They also voted to lock in electricity supply costs through 2012.

Selectmen voted on Dec. 17 to have the owner of the burned-out apartment building at 90 Main St. demolish it within 30 days after he was served with paperwork. Thomas Harville of Skowhegan owned the building when two juveniles were accused of setting it on fire on March 7, 2008. He had no insurance on it.

Interim Town Manager Kristal Flagg told the board Monday that the owners have 45 days to appeal after the board issued its decision last month.

Flagg said previously that a tax lien on the property for nonpayment of taxes for 2006 was to foreclose in February. Property taxes are also owed for 2007 and 2008, she said.

If the taxes are not paid for 2006, the town will own the property on Monday, Feb. 2, Flagg said.

If the owner or the others with an interest don’t appeal the board’s decision to demolish it by Feb. 2, then the town may tear down the building and remove the debris, she said. Selectmen also may decide to sell the property minus the building to recoup the cost of demolition.

Bids for demolition are due back on Feb. 2 and selectmen plan to open them during their meeting at 6:30 p.m. that night.

Selectmen also voted to lock in electricity supply prices for the municipal building and sewage treatment plant at 0.107 cents per kilowatt-hour with Patriot Energy of Massachusetts. The price of the higher voltage power is 0.1375 per kilowatt-hour now and is expected to rise to 0.1376 cents in February, Flagg told the board.

They also locked in prices for the highway garage, fire station, library and other eligible buildings at 0.1031 cents per kilowatt-hour. That price is 0.1098 cents now.

Flagg said electricity suppliers are forecasting that rates will increase by 11 percent from March to February 2010, and an additional 11 percent the following year.

A bid package was submitted to Maine Power Options to try to get a price on heating oil and diesel fuel as of July 1. The town is paying $4.05 per gallon for heating fuel and $4.295 for diesel fuel, a price the board locked into last year when prices were expected to escalate.

Flagg said she is hoping to get heating fuel at $2.27 a gallon for the next fiscal year and does not know what the cost of diesel will be.

In other business, selectmen voted to sell an older-style air compressor that had been used by the Fire Department to Larry Brown for $223.23. He was one of two bidders for the equipment. The other bidder was Warren Smith at $122.
