Officials at Lincoln Paper and Tissue now say the layoff of more than 200 employees is related to the loss of a major contract to an overseas business and not just a boiler explosion last month.
The company recently filed a petition with the Department of Labor for federal help, known as Trade Adjustment Assistance.
Senators Susan Collins and Angus King are asking for the petition to be approved.
They say the mill’s largest tissue customer is moving production needs to Indonesia.
That customer bought half of the operating capacity of the company’s largest tissue machine.
If the Trade Adjustment Assistance is approved, it would provide job training and other resources to laid off workers.
Last week, company officials said up to $50 million in repairs to the mill’s recovery boiler forced them to cut jobs.
