Necarney Creek Clearcutting
Threatens Short Sand Beach

Aerial Spraying Update — by Carl Whiting, PhD

From the monthly newsletter of the Rockaway Beach Citizens for Watershed Protection

Weyerhaeuser is spraying chemicals above Short Sands again. As a recent subscriber to the

Oregon Department of Forestry's FERNS NOAP notification system, I received email notifications for two clear-cut parcels of private timberland, Necarney Falls and Necarney Flats. Both parcels abut Necarney Creek, which runs into Short Sands and is classified as a Type-F fish-bearing stream. Both parcels are multi-acre clear-cuts owned by Weyerhaeuser, and are situated mere walking distance up Necarney Creek from Oswald West State Park. Necarney Flats was aerially sprayed with glyphosate, imazapyr, sulfameturon methyl, and metsulferon methyl last September.

Weyerhaeuser aerially sprayed the parcel again earlier this month with a new cocktail of chemicals, including clopyralid, sulfometuron methyl, and indaziflam. EPA labeling for Indaziflam specifically prohibits aerial spraying of this chemical due to its extreme toxicity to fish, invertebrates, and aquatic plants, an increased risk of drift, and the high likelihood of transport in ground and surface water.

This is particularly concerning because Necarney Flats ends in a long, very steep slope directly into Necarney Creek. A request for more information on Weyerhaeuser’s planned aerial application of this chemical was met with the statement that the applicator (Western Helicopter Services) was using Indaziflam as brand-named Esplanade F, produced by Bayer Chemical.

The EPA label for this brand-name of the chemical does not carry the aerial spray prohibition, despite the fact that Indaziflam is its only active ingredient (19.05 percent). All other Indaziflam/Esplanade products (for example, Esplanade 200SC) with the exact

same active ingredient (19.05% Indaziflam) are prohibited by the EPA from being sprayed aerially. How one specific brand-name of this same chemical is exempted from aerial prohibitions designed to protect fish and other wildlife is not explained in any

literature discovered to date. Further research into the granting of this exemption or omission is needed.

In addition to the risk of aerial drift, Esplanade F EPA labeling contains the following run-off warnings:"Surface Water Advisory: This pesticide may impact surface water quality due to runoff of rainwater. This is especially true for poorly draining soils with shallow groundwater. This product is classified as having high potential for reaching surface water via runoff for several months or more after application.”

“Groundwater Advisory: This pesticide has properties and characteristics associated with chemicals detected in groundwater. This chemical may leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow."

The FERNS NOAP application makes no mention of Necarney Creek, nor any written plan to protect it, despite the fact that previous NOAP applications for this exact parcel — including the aerial spray plan for last fall — were required to list the creek as a natural resource, and contained detailed written plans approved by the forester to mitigate the risk of contaminating this resource, including: "The presence of seasonal waters will be field verified prior to application by walking all stream channels."

Necarney Creek hasn’t moved since last Fall. Where did the written plan requirements go?
