Residents have lost their fight to stop a wood-burning power station being built within a short distance of their Lychpit homes.
Their objections were overruled by Hampshire County Council regulatory committee which gave the controversial scheme the green light.
Sixty-six protestors wrote to the committee calling for the scheme, earmarked for a former waste paper recycling building in Armstrong Road, to be thrown out because of health fears.
They said fumes from the power station's chimney, which will burn wood chippings 24-hours a day, would cause air pollution over their homes.
The residents were supported by Old Basing Parish Council which feared the emissions would be toxic because the wood, formerly pallets, may have been treated with lead paint and other substances.
But the committee, which received four emails supporting the scheme, brushed aside the objections and said the station, designed to provide 750kw of electricity to the national grid, would have a "negligible impact" on air quality.
Before the power station can start operating, an Environment Permit is required from the Environment Agency.
The Agency will issue the permit only if it is satisfied with the
committee's findings on air pollution.
