Background Formerly CF Industries

CF Industries, Inc., a subsidiary of CF Industries Holdings, Inc., is one of North America’s largest manufacturers and distributors of nitrogen and phosphate fertilizer products.
Founded in 1946 as a fertilizer brokerage operation by a group of regional agricultural cooperatives, CF Industries grew by expanding its distribution capabilities and diversifying into fertilizer manufacturing. Through 2002, the company operated as a typical supply cooperative. However, in 2003, in response to changing market conditions, it adopted a new business model that established financial performance, rather than the traditional cooperative charge of providing an assured supply of product to its owners, as its principal objective.
In 2005, an Initial Public Offering completed the company’s transition and established CF Industries Holdings, Inc. as a public company. Its common stock is traded on the New York Stock Exchange under the symbol “CF.”

General The Plant City phosphate fertilizer manufacturing plant converts the phosphate concentrate produced at the company’s Hardee County, Florida operation into approximately 2.1 million tons of phosphate fertilizer each year. Products are diammonium phosphate (DAP) and monoammonium phosphate (MAP).
The Plant City facility, one of the largest integrated ammonium phosphate fertilizer complexes in the U.S., is ideally sized to the company’s mining and beneficiation operations. To produce phosphate fertilizer, it receives concentrate via unit train from Hardee County, as well as ammonia and sulfur via rail and truck from its Port of Tampa operations.
The fertilizer manufacturing plant ships finished product via rail and truck to customers and to the company’s Port of Tampa warehouse for cross-Gulf and export sales.

News July 4, 2019 - Mosaic has announced that it will permanently close its Plant City fertilizer plant, which has been idled since 2017 because of slowing demand for phosphate.However, some employees will have to remain on site to help decommission one of the plant’s phosphogypsum stacks, a process company officials expect to take several years. To get rid of the water on top of it, the company has been transferring some of it to other facilities every day since 2017, according to spokeswoman Jackie Barron.Such gypsum stacks, built with slightly radioactive material from phosphate processing, loom over the Florida landscape, with a pool of acidic water on top. In 2016, a sinkhole opened beneath a Mosaic gypsum stack in Mulberry, draining the pool on top into the aquifer and setting off a major public health scare and public relations problem for the company.The Plant City plant has two of the stacks, but the first closed in 2004. Started in 1965 on State Road 39 just south of the Hillsborough-Pasco county line, the facility once employed 430 people. It could produce 2 million tons of fertilizer a year from the material dug up in the mines of Central Florida. In its last year, it cranked out only 1.3 million tons.The plant operated at a higher cost than other Mosaic facilities in Florida, and when the global demand for fertilizer began dropping, the company chose to relocate many of its employees and shut it down temporarily.More than 200 employees were offered new spots and 131 opted for early retirement while another 98 took severance packages, Barron said. Now the plant will be closed permanently.“Our decision to close the Plant City phosphate facility reaffirms our commitment to low-cost operation,” Mosaic president and CEO Joc O’Rourke said in a news release sent out by the company.During the second quarter, Mosaic expects to recognize a notable non-cash charge of up to $390 million for the permanent closure of the facility, including asset write-offs and an increase of the asset retirement obligation liability. Annual cash payments to manage the closure of the facility over the next five years are expected to be similar to payments incurred while the plant was idle in 2018.The company news release mentions the possibility of “repurposing part of the facility for productive use,” but offers no details about what that might mean.Mosaic has been working hard to shift its Florida operations southward. Last year, DeSoto County commissioners voted 4-1 to deny the company a zoning change on 18,000 acres that would allow it to open a new mine there. But earlier this year the commissioners voted unanimously to void that vote and let Mosaic come back and try again in four years.The Plant City plant was one Florida facility not targeted by the U.S. Environmental Protection Agency for mishandling hazardous waste. In 2015 Mosaic settled with the EPA for improper storage and disposal of waste from the production of phosphoric and sulfuric acids, key components of fertilizers, at Mosaic’s facilities in Bartow, New Wales, Mulberry, Riverview, South Pierce and Green Bay in Florida, as well as two sites in Louisiana.The EPA said it had discovered Mosaic employees were mixing highly corrosive substances from its fertilizer operations with the solid waste and wastewater from mineral processing, in violation of federal and state hazardous waste laws.

- Mosaic announced Tuesday it will close its Plant City fertilizer plant at the end of 2017 for at least a year to cut costs and improve profitability.  The plant, on State Road 39 just south of the Hillsborough-Pasco county line, has a work force of 430. The company said it is offering 200 voluntary retirement incentive packages to its Florida employees and has created about 100 more open positions through a hiring freeze over the last several months.  "The hope is to place as many of those impacted employees as possible in open positions in the company’s other facilities," Mosaic spokeswoman Jackie Barron said.  Mosaic has Florida operations in Hillsborough, Polk, Manatee and Hardee counties. Those not placed elsewhere will receive a severance package based on, among other things, their number of years with the company and pay.  The Plant City facility opened in 1965 and has the capacity to produce 2 million tons of fertilizer a year, the company said.  "Our business performed well in the third quarter, notwithstanding the impacts of Hurricane Irma on our phosphates operations," Mosaic president and chief executive officer Joc O’Rourke said on a conference call to announce the company’s third-quarter earnings.  "We are making the move in Florida for several reasons," he said. "Plant City is the highest-cost facility amongst our Florida operations, and it requires a disproportionate amount of sustaining capital each year."  Idling the plant, he said, should help the company optimize capital investments and allow it to increase production at its most efficient Florida facilities to offset the tons produced at Plant City. And it also gives the company the option to re-open the Plant City plant if demand grows.  "While these decisions are difficult and have impacts on our employees, today’s actions put Mosaic in a strong position to benefit as market dynamics improve," O’Rourke said.

March 17, 2014
- The Mosaic Company has completed its acquisition of the phosphate business of CF Industries, Inc. for $1.2 billion in cash plus $200 million to fund the company's asset retirement obligation escrow.  Mosaic has acquired a 25,000-acre phosphate mine and beneficiation plant, a phosphate manufacturing facility and an ammonia terminal and finished product warehouse facilities in the Tampa area. The facilities currently produce approximately 1.8 million tonnes of phosphate fertilizer per year, which will bring Mosaic's annual phosphates capacity to over 11 million tonnes.  Mosaic funded the acquisition with cash, a portion of which Mosaic plans to replace with pre-payable intermediate term debt financing. The company intends to repay this debt financing as it generates excess free cash flows.  "This acquisition provides opportunities for enhanced operating efficiencies, lower production costs and reduced capital investment—creating value for our shareholders, customers and employees," said Mosaic President and Chief Executive Officer James T. Prokopanko. "The addition of these new phosphate assets further solidifies Mosaic's position among the largest, most efficient and lowest cost phosphate producers in the world."  The acquisition is additive to Mosaic's existing Florida operations, and complements the company's plans to mine phosphate rock reserves in Hardee and Desoto counties and extensions of the existing Wingate mine. The former CF mine's proximity to Mosaic's planned Ona mine creates substantial opportunities for operational synergies.  "We are thrilled to welcome CF's Florida phosphate employees to Mosaic," said Gary N. "Bo" Davis, Mosaic Senior Vice President - Phosphate Operations. "This addition will strengthen our operations and our deep commitments to the Central Florida communities where our employees live and work."

August 6, 2010
- CF Industries Holdings, Inc. today announced that it has agreed on the terms of a consent decree with the U.S. Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection involving compliance with the Resource Conservation and Recovery Act (RCRA). The agreement resolves a Notice of Violation (NOV) issued in 2005 that alleged that certain practices at the company's Plant City, Florida phosphate complex violated RCRA. The consent decree will not be final until it has been approved by a federal court.  Under the terms of the agreement, the evolution of which has been described in previous disclosures, the company will pay a civil penalty of approximately $700,000, modify certain operating practices, undertake capital projects and accelerate approximately $55 million of funding for future closure, maintenance and monitoring activities. Additional funding may be required in future years.  "We are pleased to have resolved this issue through a negotiated settlement that reaffirms our commitment to environmental stewardship," said Stephen R. Wilson, chairman, president and chief executive officer of CF Industries. "We have always sought to lead the industry in implementing practices that protect our natural resources, such as construction of our industry-first fully lined phosphogypsum stack system at Plant City."  The 2005 NOV arose from the EPA's broad phosphate industry enforcement initiative. The company believes it was in the best interest of shareholders to negotiate this pioneering agreement in response to that initiative. In doing so, the company has not admitted any violation of law or regulation.
