Do not apply endosulfan to fields under irrigation. 2 . Do not irrigate fields treated with endosulfan for 72 hours following application. L3 . Do not apply more than 1 . 5 lbs . a. i . /acre/application. Orchard crops and strawberries are exempted. 4 . A minimum 300 foot buffer zone shall exist between the treated area and a f drain or canal to contain irrigation/rain runoff before it is discharged 6 into surface waters . The buffer zone may be a fallow field, pasture land or an untreated portion of the field. I. AERIAL APPLICATION ` 5 . Endosulfan shall not be discharged at a height of more than 10 feet above ` the crop or target . Discharge shall be shutoff whenever it is necessary to raise the equipment over obstacles such as trees or poles . 6 . Do not apply endosulfan when the wind velocity exceeds 10 miles per hour L (m.p.h. ) . 7 . The flow of liquid to aircraft nozzles shall be controlled by a positive shutoff system as follows : (1) each individual nozzle shall be equipped with a check valve and the flow controlled by a suckback device or a L boom pressure release device; or (2) each individual nozzle shall be equipped with a positive action valve. 8 . Aircraft nozzles shall not be equipped with any device or mechanism which Lwould cause a sheet, cone, fan, or similar type dispersion of the dis- charged material, except as otherwise provided. 9 . Aircraft boom pressure shall not exceed 40 psi . 10 . Aircraft nozzles shall be equipped with orifices directed backwards, L parallel to the horizontal axis of the aircraft in flight . 11 . Fixed wing aircraft and helicopters operating in excess of 60 m.p.h. shall be equipped with jet nozzles having an orifice of not less than 1/6 inch in diameter. 12 . Helicopters operating at 60 m.p.h. or less shall be equipped as follows: (1) nozzles having an orifice not less than 1/16 inch in diameter, a L number 46 (or equivalent) or larger whirlplate may be used; or (2) fan nozzles with a fan angle number not larger than 80 degrees and a flow rate not less than one gallon per minute at 40 psi (or equivalent) ; or ' (3) the Microfoil (R) boom (a coordinanted spray system including airfoil Lshaped nozzles with each orifice not less than 0 . 013 inches in diameter) . 13 . The working boom length on fixed wing aircraft shall not exceed 3/4 of the i wing span. The working boom length on helicopters shall not exceed 6/7 of L the total rotor length or 3/4/ of the total rotor length where the rotor length exceeds forty (40) feet . 1_ *** Last Page *** L r 6
