(1) Outdoor
				  production pesticide apphcations.
(a) During
				  any outdoor production pesticide apphcation, the agricultural employer must not
				  allow or direct any worker or other person, other than an appropriately trained
				  and equipped handler involved in the apphcation, 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 apphcation is complete.
(b) A summary of outdoor production
				  application exclusion zones (AEZ) can be found in Table I and is defined as
				  follows:
(i) The apphcation exclusion zone is
				  the area that extends one hundred feet horizontally from the apphcation
				  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 apphed 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
				  apphcation exclusion zone when the pesticide is apphed in a maimer other than
				  those covered in (a)(i) and (ii) of this subsection.
(c) During any outdoor production pesticide
				  apphcation, 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 postapphcation entry restrictions specified
				  in WAC 296-307-10920 is the treated area.

Entry Restrictions* - During Outdoor Production
					 Pesticide Apphcation (AEZ)
Note:
This applies to the area within the boundaries of the
							 estabhshment, outside establishment boundaries, the handler must suspend
							 application long enough to ensure no contact with any persons within the AEZ
							 (see WAC 296-307-11215(1) and (2)). Subsection (l)(b) and (c) of this section.
							 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 296-307-10915)
Prohibit workers and any persons, other than
								appropriately trained and equipped handlers, from being in the
								AEZ:
(A)Aerially
(B)Air blast apphcation
(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, fog, or aerosol
Area that extends 100 feet
horizontally in all directions from the application equipment until after the
								application is complete.
Not apphed as (A), (B), (C), or (D) above
								and:
- From a height of 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.
* During pesticides being applied:
(WAC 296-307-10915)
Prohibit workers and any persons, other than
								appropriately trained and equipped handlers, from being in the AEZ:
