New York: After years of fighting in court, lawyers representing the city, construction companies and more than 10,000 ground zero rescue and recovery workers have agreed to a settlement that could pay up to $657.5 million to responders sickened by dust from the destroyed World Trade Center.

The settlement was announced Thursday evening by the WTC Captive Insurance Co., a special entity established to indemnify the city and its contractors against potential legal action as they moved to clean up the site after the Sept. 11, 2001, terror attacks.

The deal, which still must be approved by a judge and the workers themselves, would make the city and other companies represented by the insurer liable for a minimum of $575 million, with more money available to the sick if certain conditions are met.

Most if not all of the money would come out of a $1 billion grant from the Federal Emergency Management Agency.

Mayor Michael Bloomberg called the settlement "a fair and reasonable resolution to a complex set of circumstances."

"The resolution of the World Trade Center litigation will allow the first responders and workers to be compensated for injuries suffered following their work at Ground Zero," he said in a statement.
