Outdoor production pesticide applications.
(a) During any outdoor production pesticide
				  application, the agricultural employer must not allow or direct any worker or
				  other person, other than an appropriately trained and equipped handler involved
				  in the application, to enter or to remain in the treated area or an application
				  exclusion zone (AEZ) that is within the boundaries of the establishment until
				  the application is complete.
(b) A
				  summary of outdoor production application exclusion zones (AEZ) can be found in
				  Table 1 and is defined as follows:
(i) The
				  application exclusion zone is the area that extends one hundred feet
				  horizontally from the application equipment in all directions during
				  application when the pesticide is applied by any of the following methods:
(A) Aerially.
(B) Air blast application.
(C) As a spray using a spray quality (droplet
				  spectrum) of smaller than medium (volume median diameter of less than 294
				  microns).
(D) As a fumigant, smoke,
				  mist, or fog.
(ii) The
				  application exclusion zone is the area that extends twenty-five feet
				  horizontally from the application equipment in all directions during
				  application when the pesticide is applied not as in (a)(i)(A) through (D) of
				  this subsection and is sprayed from a height of greater than twelve inches from
				  the planting medium using a spray quality (droplet spectrum) of medium or
				  larger (volume median diameter of 294 microns or greater).
(iii) There is no application exclusion zone
				  when the pesticide is applied in a manner other than those covered in (a)(i)
				  and (ii) of this subsection.
(c) During any outdoor production pesticide
				  application, the agricultural employer must not allow or direct any worker or
				  other person, other than an appropriately trained and equipped handler involved
				  in the application, to enter or to remain in the treated area or an application
				  exclusion zone that is within the boundaries of the establishment until the
				  application is complete.
(d) After
				  the application is complete, the area subject to the labeling-specified
				  restricted-entry interval and the post-application entry restrictions specified
				  in WAC
				  16-233-116
				  is the treated area.

Entry Restrictions* - During Outdoor Production
					 Pesticide Application (AEZ)
Note:
This applies to the area within the boundaries of
								  the establishment, outside establishment boundaries, the handler must suspend
								  application long enough to ensure no contact with any persons within the AEZ
								  (see WAC
								  16-233-211(1)
								  and (2) ). During pesticide application and
								  after application is complete, pesticide labeling-specified restricted-entry
								  intervals and post-application restrictions apply to the treated area.
*During pesticides being
								  applied:
(WAC 16-233-111 )
Prohibit workers and any persons, other
								  than appropriately trained and equipped handlers, from being in the
								  AEZ:
(A) Aerially
(B) Air blast application
(C) As a spray quality (droplet spectrum) of
								  smaller than medium (volume median diameter of less than 294 microns)
(D) As a fumigant, smoke, mist, fog, or
								  aerosol
Area that extends 100 feet
horizontally in all directions from the application equipment until
								  after the application is complete.
Not applied as (A), (B), (C), or (D) above
								  and:
-From a height greater than 12 inches from the
								  planting medium; and
-As a spray using a medium or larger spray
								  quality droplet spectrum of volume median diameter of 294 microns or
								  greater.
Area that extends 25 feet
horizontally in all directions from the application equipment until
								  after the application is complete.
Otherwise - No AEZ
Follow applicable label directions for
								  restricted-entry intervals.
