Authors of the historic $657-million settlement proposal for Ground Zero responders predicted Friday that it would get wide support from victims, while the federal judge overseeing the deal gave it an early thumbs-up and hinted he would slice lawyers' fees.

"I think we'll have 99 percent," said Paul Napoli, whose Manhattan law firm headed up negotiations for the 10,000-plus plaintiffs whose claims would be resolved. "When people are faced with the choice of reasonable compensation versus years of litigation, they will opt for taking the money now."

Some victims echoed that optimism but said their decision would have an edge to it after waiting nearly a decade for the city to acknowledge responsibility for the thousands whose bodies broke down after they rushed to the Twin Towers to help.

"This is the first light we've seen in the tunnel," said Kevin Larkin, 56, a retired firefighter from Middletown, N.Y., suffering from asthma and esophageal problems who came to court Friday. "But it's taken a little long. They've put a lot of people through things they didn't deserve."

Others, however, were skeptics about the deal, which provides far less than the $7 billion paid out by the Sept. 11 Victims Compensation Fund. "I just don't believe this is enough money," said John Feal of Nesconset, an advocate for responders whose foot was crushed during demolition work at Ground Zero.

The settlement, first revealed Thursday night, will only take effect if at least 95 percent of claimants agree to go along within 90 days. It calls for payments of between $575 million and $657 million to victims from the World Trade Center Captive Insurance Co., which was given $1 billion in federal funding in 2004 to insure the city and its contractors.

The amount of individual payments would range from a few thousand dollars to millions, depending on the severity of injuries - from respiratory problems to cancers to death - as well as the duration of exposure to the toxic brew left at Ground Zero and the strength of the causal link between an injury and the site.

"This will not be a giveaway," said U.S. District Judge Alvin Hellerstein, telling a packed courtroom that the deal finessed a raft of medical issues, legal defenses and endless trials for thousands of cops, firefighters and other workers. "It will be as fair and just as we can make it."

Many of the retainers signed by claimants call for their lawyers to get one-third of any recovery. But Hellerstein - who must approve both the settlement and attorney fees - said he would consider cutting the lawyers' share to 15 percent.

"There are special circumstances involved with a tragedy like Sept. 11 that do not allow for the normal rules," said the judge. "This will be one area of special attention."

Details of the 3-inch-thick settlement, released Friday morning, indicate that all qualified claimants would get at least $3,250, based on fear of cancer, while cases of death or severe cancers could top $2 million. Napoli said a typical case of breathing impairment might be worth $40,000 to $50,000, while someone who needed an oxygen tank might get $1 million.

In addition to those payments, which the insurance fund hopes to complete in a year, the settlement provides additional funds to pay for permanent disabilities, surgeries and orthopedic injuries and funds an insurance policy that will provide $100,000 to anyone who settles and subsequently develops cancer.

Kenneth Feinberg, the Washington lawyer who managed the original Sept. 11 victims' fund, said it never made sense that thousands of responders were left out of Congress' original plan, and praised the new deal.

"I really do think this closes a final chapter in one of the lingering injustices left by the Sept. 11 fund," Feinberg said. "This settlement goes a long way in correcting that injustice."
