Critics of the bill argued that the deadline for meeting the standards was unnecessarily delayed until 2006—a period of 12 years—to enforce better water quality. They also maintained that it did not force sugarcane farmers, who were the primary polluters, to pay enough of the costs, and increased the threshold of what was an acceptable amount of phosphorus in water from 10 ppb to 50 ppb.[40] Governor Chiles initially named it the Marjory Stoneman Douglas Act, but Douglas was so unimpressed with the action it took against polluters that she wrote to Chiles and demanded her name be stricken from it.[40] Despite criticism, the Florida legislature passed the Act in 1994. The SFWMD stated that its actions have exceeded expectations earlier than anticipated,[41] by creating Stormwater Treatment Areas (STA) within the EAA that contain a calcium-based substance such as lime rock layered between peat, and filled with calcareous periphyton. Early tests by the Army Corps of Engineers revealed this method reduced phosphorus levels from 80 ppb to 10 ppb.[42] The STAs are intended to treat water until the phosphorus levels are low enough to be released into the Loxahatchee National Wildlife Refuge or other WCAs.
