Herbicide Application Specifications v. 2016 Mt. Baker-Snoqualmie National Forest

Applicators will supply all chemicals, surfactants, dye, and required safety gear (listed on herbicide label and MSDS). Applications will follow all herbicide label guidelines. Applicators will wear appropriate personal protective equipment. Any preparation, transport, or application of herbicide will be conducted by, or supervised by, trained workers with a current Washington State pesticide applicator’s license with endorsements (i.e., ROW, Aquatic, Agriculture, Turf and Ornamental, etc.) that pertain to the site being treated.

The following stipulations apply:

Herbicide Transportation, Mixing, and Handling

1. Herbicide and surfactant containers must be secured and prevented from tipping during transport.

2. Herbicide and surfactant will not be mixed within 300 feet of riparian areas, wetlands, or surface water. Mix over an impervious material.

3. Workers will carry only enough herbicide daily to cover the proposed treatment for that day.

4. Hard-copies of the Material Safety Data Sheets and pesticide labels covering herbicides and adjuvants must be carried in each vehicle at all treatment times, and made available to interested members of the public, on-site.

5. A bright, non-toxic blue dye must also be used with the herbicide mix.

6. The lowest effective herbicide use rates will be used for each treatment situation.

7. Equipment fueling sites will be at least 150 feet from lakes, wetlands, or stream channels.

Herbicide Application

8. Applicators may choose to use any applicable herbicide formulation as listed in Table 1.

Additional formulations may be requested. Distance from water (as shown in Table 3.)

determines whether or not to use an aquatic formulation.

Green Grouse Stewardship IRSC Solicitation 1204H120R4001 Page 2 of 7

9. For the first year of treatments, applicators must choose the First Choice Herbicide listed in Table 2.

10. For any subsequent treatment, applicators may choose either the First Choice or Other

Choice Herbicide listed for the target species as listed in Table 2.

11. Follow the herbicide use buffers as indicated in Table 3 when working within 100-feet of a perennial or dry intermittent steams, roadside ditch, lake or wetlands. Buffers vary by herbicide active ingredient and application method.

12. All aquatic adjuvants and surfactants listed as approved on the WA DOE website may be used: http://www.ecy.wa.gov/programs/wq/pesticides/regpesticides.html. Vegetable oils and silicone blends that contain alkyl phenol ethoxylate ingredients may be used. POEA will not be used.

13. Treatments using picloram, imazapyr, and metsulfuron methyl are limited to once every other year.

14. Treatments using aminopyralid are limited to one application per year. NOTE: This is more restrictive than the pesticide label.

15. Avoid using picloram, imazapyr, metsulfuron methyl, and/or sulfometuron methyl on bare or compact soils that are highly disturbed.

16. Do not apply herbicides when local weather forecast calls for greater than 80% chance of rain.

17. Do not broadcast spray when wind speed at the application site exceeds five miles per hour or when a temperature inversion may be present.

18. To minimize herbicide application drift during broadcast operations, use low nozzle pressure; apply as a coarse spray, and use nozzles designed for herbicide application that do not produce a fine droplet spray, e.g., nozzle diameter to produce a median droplet diameter of 500-800 microns.

19. Do not apply triclopyr to edible target plant (berries) when fruit is present.

20. If heritage resources (Indian human remains, pottery, arrowheads, and evidence of native settlements, etc.) are discovered, stop work, secure find, and notify the contact person listed below.

Reporting

21. Applicators must provide both a copy of the approved WSDA Pesticide Application Record and the MBS Supplemental Data Sheet for each application site. The forms must be completed the same day as the application. The spray record must be a daily record (spreadsheets are acceptable).

22. Within 2 weeks after all work has been completed, please provide the spray records and invoice (if applicable) to the USFS contact person.

23. The applicator must post signs prior to treatment at the treatment site that indicates the product applied, the date applied, target species, and the name and phone number of the USFS contact person. Signs will be provided by the Forest Service. The Forest Service will also remove the signs.

1Broadcast Spraying, herein, is defined as an herbicide treatment method generally used along roads;

boom truck spray is directed at target species. Broadcast methods are used for larger infestations where spot treatments would not be effective.

2Spot Spraying, herein, is defined as an herbicide treatment involving use of a backpack sprayer or other means. Application is aimed at specific target species, with methods of prevention (such as barriers) to control damage to non-target species.

3Hand-Selective, herein, is defined as an herbicide treatment of individual plants through wicking, wiping, injecting stems, basal treatments, and cut-stump treatments with low likelihood of drift or delivery of herbicides away from treatment sites. This method ensures no herbicide directly contacts soil.

4Waterline, herein, is defined as the current edge of the standing water. Also known as “present flow”.

(See Figure 1 below) 5Bankfull, herein, is defined as the water level, or stage, at which a stream, river or lake is at the top of its banks and any further rise would result in water moving into the flood plain. (See Figure 1 below)
