FILE - This Aug. 17, 2006 file photo shows the normally clear water of Blackwater Sound are seen as a dark greenish blue, in Key Largo, Fla. When the Obama administration agreed to set the first-ever federal limits on runoff in Florida, environmental groups thought the state’s waters would finally get clean from a nutrient overdose that spawns algal blooms, suffocates rivers, lakes and streams, and forms byproducts in drinking water that could make people sick. The Florida rule is one of a string of regulations delayed at federal agencies, or at the White House office responsible for reviewing new rules. Together, they highlight the administration’s cautiousness in an election year, where it has been increasingly under attack by Republicans and business groups for favoring big government and costly regulations that they allege kill jobs.
