bloom conditions necessitate aerial

application, AND the property

operator obtains a written

recommendation from a licensed pest control adviser.

OR

YES NO A. Persons performing pest control for hire using pesticides listed in Attachment I must

make the followin g determinations and shall com p l y with the a pp licable restrictions:



### D. These uses and sites are exempt from the requirements presented in these draft surface water regulation concepts. 

### B. Is the pesticide being used for the following: injections into soil; applications immediately incorporated into soil; applications to animal burrows; injections in to or painted or wicked onto trees, shrubs, or other plants; or intentional applications to water that are in compliance with a ll regulatory requirements?



### J. For all ground applications, wind speed shall be 3 – 10 miles per hour at the perimeter of the application site on the upwind side. 

### G. Ground application other than airblast or high-pressure wand or hand gun.



### I. The application shall not be made within

25 feet of an y sensitive aquatic site. 

### H. The application shall not be made within

100 feet of an y sensitive a q uatic site. 

### F. Ground applied by airblast or high-pressure wand or hand gun. 

### E. Will the pesticide be ground applied by airblast

or high-pressure wand or hand gun, OR will it be ground applied by another method? 

### C. Is the pest control business making the pesticide application certified by an organization that has adopted the standards or requirements of a green or sustainable program approved by the director, and will the application be in compliance with those standards or requirements?

### Part III: Runoff Management to Protect Surface Water Agricultural Production

OR

YES NO

OR

OR B. Is the pesticide being applied to the following: apiaries; aquaculture; livestock production (meat or milk); post-harvest commodity treatment on the farm; poultry production (meat or eggs); injections into soil; applications immediately incorporated into soil; applications to animal burrows; injections into or painted or wicked onto trees, shrubs, or other plants; intentional applications to water that are in compliance with all regulatory requirements; or ap plications made to hydrologically isolated sites?



### C. If both of the following are met: (1) At the time of the application, the operator of the property

obtains and follows a written recommendation from a licensed pest control a dviser for the pesticide application. and (2) At the time of application, the operator of the property possesses and is implementing a surface water quality management plan, as defined in Attachment II, to prevent the pesticide from leaving the property at levels that would not protect beneficial uses of water.



### D. These uses, sites or conditions exempt the application from the requirements presented in these draft surface water

re g ulation concepts.



### E. Do not make pesticide applications if soil moisture is at field capacity and a storm event, forecasted by the Na tional Weather Service, is to occur within 48 hours following application; or a storm event likely to produce

runoff from the treat ed area is forecasted by the National Weather Service to occur within 48 hours following the application.



### J. For four weeks after application, divert any

r ain runoff with an on-site recirculating system

and/or contain and hold any rain runoff for 72 hours before releasing into a sensitive aquatic

site or into a ditch or drain that ultimately

discharges into a sensitive aquatic site. 

### F. Apply the pesticide only if the application is followed by the use of a technology or product that rapidly degrades or reduces offsite movement of the pesticide so that it will not adversely affect water quality.



### I. For four weeks after application, divert any irrigation runoff with an on-site recirculating system and/or contain and hold any irrigation runoff from the time irrigation is started on any part of the field until 72 hours after irrigation is completed on the entire field, before releasing into a sensitive aquatic site

or into a ditch or drain that ultimately discharges into a sensitive aquatic site. 

### G. For irri g ation runoff

K. For pesticides also listed in section 6800(a) of Title 3 of the California Code of Regulations (3 CCR), and applied during the period October 1 through

March 31 , comply with the appropriate management practice in 3 CCR section 6487.4.

For applications of 6800(a) pesticides during the period April 1 through September 30 , comply with the provisions described above under the heading “For rain runoff.”



### H. For rain runoff A. The operator of the property to be treated with pesticides listed in Attachment I

, and persons performing pest control for the operator, must make the following determinations and shall comply with the applicable restrictions:

### Part IV: Runoff Management to Protect Surface Water NonProduction Agricultural, Outdoor Structural, Residential, Industrial,

and Institutional Use

OR

YES NO

OR D. These uses and sites are exempt from the requirements presented in these draft surface water regulation concepts. 

### B. Is the pesticide being used for the following: injections into soil; applications immediately incorporated into soil; applications to animal burrows; injections into or painted or wicked onto trees, shrubs, or other plants; intentional applications to water that are in compliance with all regulatory requirements; or applications as enclosed baits?



### F. Comply with the following: 1. Do not make applications to nonproduction agricultural, outdoor industrial, outdoor institutional or outdoor structural sites if a storm event, forecasted by the National Weather Service, is to occur within 48 hours following the application; AND

2. All outdoor non-term iticide applications to impervious surfaces such as sidewalks, driveways, patios, porches, and structure walls or siding shall be limited to spot and crack-and-crevice applications only. This does not apply to applications to building foundations, up to a maximum height of three feet; AND 3. Sweep pesticide granules o ff nonpervious surfaces following application; AND 4. If the concrete slab is not to be poured before rainfall is possible, cover termiticides after application to prevent runoff; AND 5. Do not make intentional applications to saturated soils; AND 6. Do not apply within ten feet of any drain; AND 7. Except when applying to sewers or drains as directed on the pesticide label, do not apply directly into sewers or drains, or to any area like a gutter where drainage to sewers, storm drains, or sensitive aquatic sites

can occur; AND 8. Do not apply unless the property operator or resident has been advised not to allow irrigation runoff for 72 hours after application. 

### E. For rain and irrigation runoff 

### C. Is the pest control business making the pesticide application certified by an organization that has adopted the standards or requirements of a green or sustainable program approved by the director, and will the application be in compliance with those standards or requirements? 

### A. Persons performing pest control for hire using pesticides listed in Attachment I must make the following determinations and shall comply with the applicable restrictions:



### G. If the pesticide is also listed in section 6800(a) and is to be applied October 1 through March 31 , the applicator shall ensure compliance with the provisions in 3CCR section 6487.4. If the 6800(a) pesticide is to be applied April 1 through September 30 , comply with the provisions described above under the heading “For rain and irrigation

runoff.”
