MANATEE -- Mosaic Fertilizer, LLC is poised to mine more of the property at its Wingate Creek Mine after a 5-2 vote today by the Manatee County Commission.

The commission approved an ordinance amending a development order that codifies existing approvals for the east Manatee project, with the changes designed partly for "administrative convenience," county documents said.

Among other things, the company will be able to mine its clay settling area, along with other unmined areas on its property, documents said.

Voting in favor were County Commissioners Carol Whitmore, John Chappie, Betsy Benac, Vanessa Baugh and Commission Chairman Larry Bustle. Voting against were Commissioners Robin DiSabatino and Michael Gallen.

The changes would affect 557 acres, including stockpile areas, a clay settling area, and 15.4 acres of technically undisturbed -- but hardly pristine -- land, officials said.

The amendment to the development order will extend by nine years the company's build-out date, or the life of the mine, to 2023; its land reclamation deadline will be extended nine years to 2027, said Rob Brown, a division manager for the county's Natural Resources Department.

The company sought to mine areas on its property formerly set aside for other uses, and is not seeking to mine new lands at this juncture, officials said.
