BERLIN, N.H. (AP) – City officials are worried about property tax revenues after the Fraser Papers Inc. pulp mill closed last spring.

The mill is being demolished, and part of the property has been sold to North American Dismantling Corp. But some buildings and land, a wastewater treatment plant, the hydropower plant and a private electric grid are still owned by Fraser Papers, which is still operating a paper mill in neighborning Gorham.

The divided ownership is a headache for Berlin, which signed a five-year property tax agreement with Fraser Papers and subsidiary Great Lakes Hydro several years ago that expires in a year. The city says the agreement, which values the entire complex at $50 million in 2007, should remain in effect next year. But the new owners may see things differently.

An appraiser says the property still has solid value, even without the mill building.
