Proposed Notice of Intent Threshold for Mosquito Control Activities.

The Proposed NOI Threshold for mosquito control is: 

1000 acres or more applied annually for pesticides applied to or over waters of the 

state. 

For Florida, this would result in nineteen districts out of fifty four that would not qualify 

for the NOI based on larvaciding and aerial adulticiding reported results. There are thirty 

districts that make aerial applications, resulting in twenty one districts that would be 

required to file NOIs. Together, the districts that would meet the NOI threshold (over 

1000 acres), represent over 98% of acreage receiving applications. 

A summary of the reported acreages treated are provided in the table below. 

This definition does not include applications “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 required to file NOIs and are subject to NPDES conditions, they 

may chose to suspend ground larvaciding operations and conduct only ground 

adulticiding operations in upland areas. This would have the unintended consequence of 

reducing the use of integrated pest management based treatment practices. 

Note: The proposed definition of “near” water 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 width 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 feet. For a hand held spray 

wand, the swath width can be established during calibration, but is typically two feet. 

Near water would then be within two feet.

County/Program. Note – there are five programs that apply aerial adulticides but not 

larvacides.
