The Florida Department of Environmental Protection last week issued an emergency rule that significantly expands the contamination reporting requirements for property owners and other responsible parties. This will be followed by rulemaking and the introduction of legislation that will implement the reporting requirement into law. The FDEP initiated this rulemaking at the direction of Governor Scott, responding to recent spills at a phosphate mine and sewage treatment plant that were not reported to the general public. The notice requirements are very broad, apparently targeting contamination both within 30 days after a spill occurs and after the contamination is discovered, no matter how long ago the spill. This could include disclosures occurring as part of the due diligence process in real estate transactions that the parties may otherwise have intended to remain confidential.
