Information on Alpine Helicopter Service Requirement to Communicate Pesticide Applications Near Sensitive Sites

Back to Reporting Pesticide Problems

Pursuant to a court order, Alpine Helicopter Service, a business which performs aerial applications of pesticides, is required to provide information to nearby homes, school sites and specific businesses classified as “sensitive sites” prior to the application of a pesticide. After finding Alpine liable for multiple violations of California law associated with repeated pesticide drift incidents, the San Joaquin County Superior Court ordered Alpine to pay civil penalties and to comply with numerous injunctive terms, including the requirement to provide pesticide use information to sensitive sites. Alpine operates in Amador, Calaveras, Marin, Sacramento, San Mateo, San Joaquin, Sonoma and Stanislaus counties. This order is effective through 2027.

If you received a door hanger, postcard, or other information from Alpine, you are considered a sensitive site that is located within ¼ mile of a planned aerial application of pesticides. You are receiving this information for the purposes of communication and awareness – Alpine’s application is subject to local oversight by County Agricultural Commissioners to ensure the pesticide is applied safely and in accordance with state and federal pesticide use laws and regulations.

If you believe you have been exposed to a pesticide during an aerial application by Alpine or elsewhere or otherwise believe a violation of any pesticide requirement has occurred, please file a complaint using the resources below:
