What to do before, during and after toxic aerial spraying

FPA (Forest Practice Application) for aerial pesticide spraying is valid for 3 years. Spraying can take place any time during those 3 years from the date of approval and may occur multiple times. Ground applications do not require permits.  Summary of DNR Silviculture Contracts has information for ground pesticide spraying by DNR. By law, only adjacent properties get a notice for an aerial  spray. Ground applications do not require permits. Please see a list of all active aerial spray FPAs with maps and some of toxic ingredients at the top of SUMMARY FOR THE LATEST FPAs (FOREST PRACTICE APPLICATIONS).  Timber corporations and DNR aerially or manually spray pesticides on industrial tree plantations in dry, calm weather.

Please support the petition to FPB for better notification and information disclosure about aerial chemical spraying. Write your comments and thoughts to .
A great message would be something as simple as “I learned that there is a petition about forest chemicals notification and reporting before the Board. I think this is a serious issue in Washington State that the Board should thoroughly discuss. I live in X place and have Y experience/basis for concern with forest chemicals.”




Pesticides Factsheet at NCAP (Northwest Center for Alternatives to Pesticides)

Campbell Global
and Weyerhaeuser are the largest tree farm managers/owners in the Valley.
On September 18 through 21 (Friday through Monday), 2015 timber company Springboard Wallace Falls LLC  executed a massive toxic aerial chemical spray under Forest Practice Applications (FPAs) # 2814793 (252 acres) and 2814705 (804 acres) for a total of 1,056 acres. The spray consisted of a mix of toxic herbicides. This application took place on four consecutive days in the Sultan Startup area, North of Hwy 2. Loud noise of the spraying helicopter attracted a lot of attention from local residents and tourists. Local community did not have any information about the spray and watched it in disbelief and dismay.
Below is an email message from October 8, 2015 by Mark Baugh, a forester of Campbell Global, manager of the tree farms, with the list of chemicals:
“Each unit is reviewed before spraying to determine what competing vegetation is in the stand, so the mix would be different for some of the stands.  Some of the stands are site preparation applications and some are release applications.  The one unit I believe is nearest to you, (Sultan-Startup Road), would be the property we have in Sec. 27, T28N08E.  That was a release spray on 115 acres.    The chemicals and rate of application were as follows:
Alligare Glyphosate 5.4               30 oz./acre
Rotary 2 SL(Imazapyr)                 2 oz/acre
SMF Extra (Oust)                      .5 oz./acre
SuperSpread MSO                        4 oz./acre”
Below is the data from Case Investigation Report NML-0025-15, Department of Agriculture:


10 gal/ acre x 1000 acres = 10.000 gal total sprayed
4 tank mixes
Alligare Glyposate 5.4, each tank mix
Alligare SFM Extra, tank mix 1 and 3
Alligare Rotary 2SL, tank mix 2 and 3
Willbur-Ellis Syl-Tak, tank mix 1
Premium MSO Methylated Spray Oil, tank mix 2 and 3
Syl-Coat, tank mix 4
Crosshair, each tank mix
  • Glyphosate (one of the trade names for products containing glyphosate is Roundup) is a potent herbicide linked to cancer. Please google “widely used herbicide linked to cancer” for more info and articles in many prominent publications;
  • SMF Extra (or Oust)  is a potent and toxic herbicide;
  • Rotary 2 SL (or Imazapyr)  is a potent and toxic herbicide;
  • Premium MSO Methylated Spray Oil is a toxic surfactant.

These and other tree farming chemicals contaminate watersheds and drinking water wells, harm wetlands, streams and rivers and everything in and around them. They are toxic for people and wildlife. Please see  below a study about this by Department of Ecology. This study confirmed that creeks and streams get contaminated during aerial spraying even after following best practices and precaution measures according to the label. It was found that all 7 streams were contaminated with pesticide pollution. In addition, pesticides are not adequately tested and are not tested at all in combinations, inert ingredients are not disclosed, and long-term impacts are not fully considered.


We are requesting changes to the following practices:

  1. Written notification for aerial herbicide and pesticide spraying to every resident, school and business of the adjacent watershed with specific date, location and chemicals to be used, including an option for email notifications;
  2. Public disclose after spraying of what chemicals were sprayed and where;  this can be accomplished through the existing online review system for FPAs (Forest Practice Applications);
  3. Monitoring and testing of toxic contamination in creeks, streams and drinking water wells of that watershed;
  4. Research on drift and relocation of toxic chemicals on and from tree farms, including direct applications and groundwater contamination;
  5. Extended buffer zones for residences, schools, businesses and streams;
  6. Establish Emergency Response Standards; the pesticide applicator must provide information on chemicals in a reasonable manner for medical assistance in case of acute exposure;
  7. Consider least toxic alternatives to pesticides and prevention methods, including cultural, biological and mechanical weed control;
  8. Information and research should be transparent and easily available online to the public.
