TERMS AND CONDITIONS
Ash tree Evaluation
: Parties interested in applying for a ROW tree treatment permit must contact the Boulder County EAB Coordinator to receive a tree evaluation prior to issuance of a permit. Some ash trees may not be suitable candidates for treatment due to poor health, structural issues, or are located in an unfavorable location. Boulder County reserves the right to deny a tree treatment permit for any reason.
Permitted Pesticides and Application Method
: Trunk injection methods of Emamectin benzoate and Azadirachtin are the only approved chemicals. Soil drenches or injections, foliar sprays and bark sprays are not permitted on public ash trees.
Time of Year
: Treatment timing is at the discretion of the applicator.
Treatment Frequency and Proof of Treatment
: Emamectin benzoate and Azadirachtin are both labeled for control of EAB for two years and require continual treatment for the life of the tree. The permittee must continue to treat a tree at the labeled frequency and rate. A State of Colorado Certified Pesticide Applicator is required to record treatment records and can make a copy available to the permittee by request. The permittee shall submit the copy to the Boulder County EAB Coordinator within 30 days of application as proof of treatment, either by email or postal service.
: : Both permitted pesticides are only available for purchase by a State of Colorado Certified Pesticide Applicator. Interested parties shall contact the Boulder County EAB Coordinator to obtain a list of county contracted tree service providers who can perform the tree treatment. Permit holders are responsible for scheduling and paying for treatment.
Limits of the Permit
: Tree treatment permits are only valid for the party listed on the permit and are not transferable. Failure to continually treat a tree at a pesticide's labeled frequency will cause the tree to be added to the tree removal list, with all expenses billed to the permittee. This permit shall expire two years after Boulder County's receipt of the most recent proof of treatment.
Treated trees will be inspected annually to ensure good health and continued protection from EAB. Trees that have been appropriately treated and documented that are found to be infested with EAB or are in declining health for other reasons will be scheduled for removal. Expenses for this work will be paid for by Boulder County. Ash trees shall be treated at the prescribed frequency for the remainder of the trees natural life. Failure to comply will result in the removal of the tree by Boulder County at the expense of the permittee. Treatment of trees in the right-of-way shall not preclude removal by Boulder County for reasons related to hazards, maintenance, construction, or any other reason, and shall be removed at the county's expense.
Permit holders that relocate to a new residence are not permitted to transfer the tree treatment permit to a new property owner and are no longer responsible for any expenses related to the permitted treated tree. New property owners may apply for a permit to continue ROW tree treatment.
