Back in 1996, Florida voters approved a “polluter pays” amendment that environmentalists hoped would force the agricultural industry — particularly sugar growers — to bankroll the hefty expense of stemming the damaging flow of nutrients into the Everglades.

It hasn’t worked out quite that way.

According to a study released Monday by the Everglades Foundation, the agricultural industry produces three-quarters of Glades pollution but pays only a quarter of the costs of cleaning it up. The public, the study found, pays the rest of an annual $106 million treatment tab through property taxes, utility bills and state and federal taxes.

“I’m quite certain that most Floridians would find it rather outrageous that they are picking up the bill for giant agricultural operations,’’ said Kirk Fordham, chief executive officer of the foundation, a group that championed the 16-year-old amendment that the Legislature has never enacted.

Fordham said he hoped the study would persuade state and federal negotiators trying to resolve decades of lawsuits over Florida’s oft-delayed clean plans to shift the burden — and bills that could run hundreds of millions of dollars or more — to farmers, ranchers and nurseries responsible for the bulk of nutrient pollution that has poisoned vast swathes of the Glades, killing off and crowding out native plants.

South Florida’s sugar farmers immediately bashed the study, which the foundation commissioned for $185,000 from researchers at North Carolina-based RTI International.

In a joint statement, the U.S. Sugar Corp., Florida Crystals Corp. and Sugar Cane Growers Cooperative of Florida defended their efforts and their record of reducing phosphorus use, saying the study was based on “grossly flawed assumptions, resulting in hocus pocus economic conclusions.’’

The Florida Department of Environmental Protection issued a statement claiming “significant progress’’ in reducing nutrients but acknowledging “that there is more to be done.’’ The statement also sent an upbeat signal about settling long-running federal lawsuits over the slow pace of clean-up, adding that “because of the leadership of Gov. (Rick) Scott, Florida is on the verge of a momentous step forward in Everglades restoration.’’

The state, which first agreed to reduce the flow of phosphorus into the Everglades to settle a federal lawsuit in 1988, has been under mounting pressure from federal judges frustrated by the decades of delay. Florida has spent more than $1.3 billion to construct a 45,000-acre network of artificial marshes to scrub phosphorus flowing from farms into the Glades but it hasn’t been enough to meet the super-low standards required to protect the sensitive marsh.

Phosphorous, a common fertilizer ingredient that drains off farms and yards with every rain storm, can trigger fish-killing algae blooms in lakes and coastal waters. But its impact can be catastrophic even at minute concentrations in the Everglades, said foundation senior scientist Tom Van Lent. As concentrations rise, it can kill off an important algae at the base of the Everglades food chain and fuel the spread of cat tails, a plant that a scientist once dubbed “the grave markers of the Everglades.’’

A host of state legislators from both sides of the aisle will announce the formation of a Florida Everglades Legislative Caucus at a press conference slated for 1 p.m. today.

The event, which will be held in Boynton Beach, will be hosted by state Rep. Steven Perman, D-Boca Raton, and Sen. Thad Altman, R-Viera.

WASHINGTON — A new fast-track planning effort could shave years off the next phase of Everglades restoration, putting more fresh and clean water into the central and southern portions of Florida’s "River of Grass" more quickly.

A restoration task force that met Thursday in West Palm Beach, Fla., announced a rapid planning effort that, if approved by Congress, could transform how large public-works projects across the country are built. It’s also expected to cut the planning process for the next major restoration project in the central Everglades from six years to 18 months.

“The reality is the ecosystem has continued to degrade,” said Dawn Shirreffs, the Everglades restoration program manager for the National Parks Conservation Association. “We’re running out of time. We don’t have the time to spend six years on a project anymore.”

Thursday’s announcement came out of the U.S. Army Corps of Engineers’ effort to streamline large projects nationwide. The Army corps decided to use the planning process for the next major restoration project, which will provide more a natural flow and deeper clean new water through the central Everglades and Everglades National Park, as a pilot.

Previous plans were overly detailed, expensive and time-consuming, the Army Corps of Engineers found. The time — as well as data — being invested in studies wasn’t leading to a better product, officials said in materials that were prepared for Thursday’s task force meeting.

Also, projects in the Everglades had a tendency to be addressed one by one rather than simultaneously, Shirreffs said. But there are three components of Everglades cleanup, all intertwined, and all best addressed together, she said. Water can’t be moved unless it’s clean, it can’t be cleaned unless it’s stored and it can’t be stored unless it gets to the places designated for storage.

Cleaning up the pollution that's flowing into the Everglades requires reducing the phosphorus in the water to 10 parts per billion. Amounts any higher won’t stop changes in plant and animal life in the Everglades, a delicate ecosystem of marshlands and forests that's home to a variety of threatened species.

Because of high levels of phosphorus, cattails have been taking over the saw grass in the Everglades for decades. The pollutant has flowed from fertilizers on sugar and vegetable farms and the sprawling suburbs of South Florida.

The state was supposed to get to its phosphorus-reduction goal by 2012, but the Florida Legislature pushed back the deadline to 2016. Earlier this month, Florida Gov. Rick Scott met in Washington with Interior Secretary Ken Salazar and offered some alternative plans for resolving some of the legal disputes over water quality in the Everglades, but he also said that Florida would need another six years.

The state's plans call for downsizing some construction projects and relying more on water storage on public and private lands. The plan, Scott said, puts to use land that's already in public ownership so that projects can be authorized and built promptly "at a reasonable cost to the taxpayers."

Specifically, the state will be looking for opportunities to use publicly owned land to store and treat water in the Everglades Agricultural Area — where farmlands exist amid the Everglades' water system — and move the water south to water conservation areas and Everglades National Park.

That’s expected to achieve more natural water circulation and tie together the state’s work north of the conservation areas and the Interior Department’s Tamiami Trail bridging project, along the highway that runs from Tampa to Miami, passing through the Everglades.

Last week, Salazar visited the Tamiami Trial project in Miami-Dade County. It’s one of the first bridges in a series of planned spans that would raise parts of the highway above the wetlands and eventually could restore the historic freshwater flow of the River of Grass to levels not seen in 80 years.

The federal government eventually would like to see 5.5 miles of bridges on Tamiami Trail, at an estimated cost of $324 million and to be built over four years. So far, it’s unclear whether money for the bridges will be budgeted, however.

Friday, officials will break ground on a separate project: a 12,000-acre reservoir in western Martin County, Fla., designed to improve the quality of the water in the St. Lucie Estuary and the southern portion of the Indian River Lagoon.

A congressional subcommittee will look next week at the U.S. Fish and Wildlife Service’s plans to acquire more land in the Everglades for conservation, how it would be paid for and what effect it would have on public access and recreation within the refuge and conservation area.
