  • Representation of an international aerospace company in two high-profile mass toxic-tort actions in which plaintiffs allege that emissions from its manufacturing facility contaminated nearby properties and potentially exposed persons near the facility. Plaintiffs seek injunctive relief, medical monitoring, and monetary damages.
  • Irizarry et al. v. Orlando Utilities Commission et al. Defended the Orlando Utilities Commission in a putative class action brought by residents alleging that emissions from a power plant contaminated approximately 15,000 properties within an approximate 80-square mile area with radionuclides, metals, and other constituents thereby elevating cancer rates. A putative class action that once included more than 30,000 residents has now been dismissed with prejudice.
  • Curd, et al. v. Mosaic Fertilizer. Currently defending Mosaic in an action by commercial fishermen alleging damages purportedly resulting from a release of approximately 65 million gallons of process water from a phosphogypsum stack, which was caused by Hurricane Frances. The case involves complex scientific issues in the disciplines of ichthyology, benthic ecology, marine biology, physical oceanography, estuarine science, and commercial fishing economics. Greenberg Traurig prevailed on a motion to dismiss plaintiffs’ claims which the plaintiffs appealed. Florida’s Second District Court of Appeal affirmed the dismissal and held that Florida law did not impose an independent duty of care to protect plaintiffs’ pure economic interests or create a private statutory cause of action for damages when the party seeking recovery does not have a possessory interest in the property allegedly damaged by pollution. The Second District certified these issues to the Florida Supreme Court as questions of great public importance. The Florida Supreme Court ruled that only commercial fishermen could proceed with their claims, limiting the putative class. Importantly, while the court ruled a claim could proceed under Florida's environmental strict liability statute, it adopted a definition of damages precluding personal injury, thus stabilizing an entire area of Florida environmental law. The case was remanded with a limited, putative class. Later, the plaintiffs filed a motion to join over 100 new plaintiffs in an effort to convert the action from a putative class action to a mass tort, which Mosaic successfully opposed, and the plaintiffs appealed. The Second District Court of Appeal affirmed the trial court ruling denying joinder. The plaintiffs sought class certification, which the appellate court reversed in the fourth appeal in this action.
  • Williams v. Mosaic Fertilizer, et al. Defended Mosaic in federal court in toxic tort litigation in which Plaintiff alleged she suffered adverse health effects as a result of airborne exposure to industrial emissions and claimed over $60 million in damages. Prevailed on all claims in the trial court on Daubert and summary judgement motions in a 41-page order and a subsequent order excluding evidence of stigma damages. See Rhonda Williams v. Mosaic Fertilizer, LLC, Case No. 8:14-cv-1748, 2016 WL 7175657 (M.D. Fla. June 24, 2016). Plaintiff appealed the trial court’s decision and the Eleventh Circuit Court of Appeals affirmed entry of summary judgment in favor of Mosaic. Williams v. Mosaic Fertilizer, LLC, 889 F.3d 1239 (11th Cir. 2018).

Defended Mosaic in complex litigation—that culminated in a multi-week federal jury trial—involving an alleged breach of land reclamation agreements concerning a 2,000+ acre former phosphate mine. Plaintiffs filed a sixteen-count complaint and sought damages in excess of $50 million. The jury returned a split verdict awarding plaintiffs approximately $1.5 million—less than 3% of what they had originally sought. The court subsequently ordered a remittitur, which reduced the damages award by more than $750,000. The case was subsequently settled while on appeal.
  • Los Angeles Unified School District v. Cronimet, et al. Defended Cronimet and United Alloys & Metals in an action filed in the Central District of California involving allegations of offsite groundwater contamination from chlorinated solvents purportedly affecting a nearby school.
  • Franco et al. v. Coronet Industries, Inc., et al. Defended Coronet in a mass toxic tort action with more than 1,100 plaintiffs asserting wrongful death, personal injury, medical monitoring, and property damage. Plaintiffs’ claims arose out of alleged contamination of groundwater, surface water, soil, and air in a large area previously mined for phosphate surrounding a facility that manufactured phosphate-based animal feed supplements and other chemical products. Plaintiffs demanded approximately $250 million in personal injury damages, property damages, and medical monitoring. We obtained the entry of one of Florida’s first Lone Pine orders requiring plaintiffs to substantiate their allegations of injury and causation or be subject to dismissal, which resulted in the dismissal of more than 300 plaintiffs. We also employed an offer of judgment strategy that resulted in the dismissal of more than 300 additional plaintiffs through de minimis settlements. The remaining claims were settled pursuant to a confidential settlement agreement, which took more than two years to negotiate and was highly favorable to our client. The action against Coronet was publicly promoted by environmental activist, Erin Brockovich.
  • Gates v. W.R. Grace & Co., et al. Defended a phosphate company in a toxic tort action filed in the Middle District of Florida arising from alleged exposure to contaminants that migrated from a chemical processing facility to plaintiff’s potable water well. Plaintiff resided approximately 600 feet from the facility’s property line and 1,700 feet from the phosphogypsum stack and cooling ponds. Plaintiff was diagnosed with acute promyelocytic leukemia, which he alleged resulted from drinking contaminated water. Testing of the well in connection with a Preliminary Groundwater Contamination Report registered exceedances of gross alpha and radium 226 and 228 in Plaintiff’s well. After conducting intensive discovery of plaintiff and non-parties, we prepared and served on Plaintiff’s counsel a proposed Rule 11 motion threatening sanctions based on the absence of specific causation. The matter was subsequently resolved for a de minimis.

  • Anderson, et al. v. Mulberry Phosphate. Defended Mulberry against claims by over 150 plaintiffs arising out of release of approximately 50 million gallons of process water into the Alafia River.

GT successfully defended an action in which plaintiffs sought to certify a class of individuals who allegedly sustained personal injuries or property damage purportedly caused by discharges of toxic or hazardous substances from the operation of a phosphate and chemical processing facility, or who sought attendant medical monitoring. The trial court denied class certification.
  • Chartis Specialty Insurance Company f/k/a American International Specialty Lines Insurance Company v. Mosaic Fertilizer and CSX Transportation. Defended Mosaic in an action filed in the Middle District of Florida seeking a recovery of past and future investigative, remediation, and removal costs under Section 107 of the Comprehensive Environmental Response, Compensation, and Liability Act, a declaratory judgment declaring the rights and duties of the parties under CERCLA, and the recovery of cleanup and management costs under Section 376.313, Florida Statutes. Kaiser Aluminum & Chemical Corporation disposed of low pH wastewater generated in its production of sodium silico fluoride, potassium silico fluoride, and synthetic cryolite. For decades, Kaiser disposed of this wastewater in an inactive drainfield. In the 1970s it began to dispose of its wastewater 5,000 feet below the site’s surface using a deep injection well. Chartis alleged that Mosaic acquired the contaminated property through a series of mergers and acquisitions and that contaminated groundwater had migrated to a neighboring minority community.

GT prepared and served plaintiff’s counsel with a proposed Rule 11 motion and the action against Mosaic was voluntarily dismissed.
