# Proposed Notice of Intent Threshol d for Mosquito Control Activities.

The Proposed NOI Threshold for mosquito control is: 1000 acres or more applied annua lly for pesticides applied to or over waters of the state. For Florida, this would result in nineteen dist ricts out of fifty four that would not qualify for the NOI based on larvaciding and aerial adultic iding reported results. There are thirty districts that make aerial applications, resul ting in twenty one dist ricts that would be required to file NOIs. Together, the distri cts that would meet the NOI threshold (over 1000 acres), represent over 98% of acreage receiving applications. A summary of the reported acreages treate d are provided in the table below.

This definition does not include a pplications “near” water. All applications “near” water would have to comply with the terms of the general permit, but the number of acres treated “near” waters of the state would not be counted toward the NOI threshold. It should be noted that, if the requirements for an NOI are set too low, and fiscally constrained districts are requi red to file NOIs and are subj ect to NPDES conditions, they may chose to suspend ground larvaciding operations and conduct only ground adulticiding operations in upla nd areas. This would have the unintended consequence of reducing the use of integrated pest ma nagement based treatment practices. Note: The proposed definition of “near” wate r is an application within one swath width of the application equipment used. For example, application by a truck based ULV adulticide rig has an operational swath wi dth of 300 feet. Therefore a “near” water application would be within 300 feet of waters of the state. For an airplane, the swath width is 1000 feet, therefore “near water” is within 1000 f eet. For a hand held spray wand, the swath width can be es tablished during calibration, but is typically two feet. Near water would then be within two feet.
