Stimson helicopter spraying sparks mystery taste and smell in Hyla Woods
State testing finds no evidence of chemical drift but case is still open
Peter and Pam Hayess claim about herbicide exposure in the forest of the Oregon Coast Range begins the same way as most from the news in recent years.
On May 17, they and two others were out tending their property. They heard a helicopter in the distance and thought little of it. Then, they say, they began to smell and taste chemicals.
The helicopter was not over me. It was not droplets. It was just a super strong, strong taste, Pam said.
Both are familiar with the idea of aerial spraying. Pam and her husband, Peter Hayes, are fifth-generation loggers and the owners of Hyla Woods in Washington County.
Peter is a former member of the Oregon Board of Forestry. Hes also become an advocate for more environmentally friendly logging practices, including the elimination of herbicides.
Hayes uses some herbicide on his property to control invasive plants, but he has a goal of getting to zero herbicide use. He applies them by hand rather than by helicopter, which many timber companies use to cover large swaths of land in the sometimes narrow window when herbicides are most effective at killing vegetation that competes with young trees.
Hayes has said he views profit at the expense of the land as a form of theft.
The Hayeses unsettling experience comes in the midst of ongoing debate about the practice of aerial spraying.
Last year, multiple bills were introduce to change the rules for the practice. This year, environmental groups and coastal residents introduced a ballot measure aiming to limit and stop the practice altogether.
The Oregon Department of Agriculture (ODA) has been investigating Hayes claim. After taking samples from the Hyla Woods property in an attempt to determine if chemical trespass occurred, ODA scientists found no detections of chemical drift onto the property. ODA staff will also review records.
The helicopter in question was hired by Stimson Lumber Company, whose property is more than a half-mile away from Hyla Woods. The application was done by Wilbur-Ellis.
We welcome the investigation and are cooperating in every way we can, said Scott Gray, Western Resource Manager for Stimson Lumber.
Gray said he was very surprised to hear from Hayes about drift, given the distance from the application site to the Hyla Woods property, which he said is more than 3,600 feet.
Gray said the application was in compliance with all the regulations that apply, and that the company used an additive in the herbicide mixture to prevent drift.
Our job is to manage the timberland, but we also have to protect all the other resources we dont own. Thats our professional responsibility we have to abide by, Gray said.
Peter Hayes urged against rushing to judgment in such a case. Stimson and Hyla Woods have been neighbors for years with a good relationship. The case was actually referred to the ODA for an exposure investigation by the Department of Forestry, not because Hayes complained directly.
Id call them friends, Hayes said of Stimson.
After the samples came back with no evidence of chemical drift, Gray said the findings show the current system works. But the states investigation is ongoing.
Regardless of what the ODA ultimately finds, Hayes feels Oregon has allowed chemical trespass to be a problem for too long.
I think we need to take a hard look at the current practice, he said, referring to helicopter spraying. Too often, it degrades the things we have in common: our air and water. Too often it has impact on other peoples lands. We need to take a solid look at it.
His complaint comes as rulings on two other high-profile aerial spray cases are still pending. The first is a lawsuit over a 2013 incident in Gold Beach. The other is an administrative hearing over whether the state was justified in suspending the license of Applebee Aviation after it violated worker protection rules.
Decisions in both cases are expected this summer, which could affect future penalties assessed by state government and the liability of farm and forest companies in such cases.
