HERBICIDE APPLICATION

2024 Crane Herbicide Weed Treatment

1. Target Species: Scotch thistle Additional noxious weed species found within the designated contract boundary, and susceptible to chemical intended for use, will also be treated.

2. Treatment Area: 3,724 acres including up to approximately 42 acres of streams/have the potential for water present and will require the use of both aquatic herbicide and adjuvant. Treatment areas vary in the amount of noxious weeds that are within the polygon. Actual weed treatments will be less than that of the treatment area itself.

3. Location of Work Site: Project area is located approximately 9 miles south-southwest of Elko, Nevada. The legal description of the treatment area is: T30N R54E, T31N R54E, & T31N R55E. See Attached Location Maps.

Access to Work Site: Public or private access roads damaged by the Contractor shall be restored, at the Contractor’s expense, to the same condition they were in at the commencement of work.

4. Approximate Performance Period: Period of performance is estimated, and timing of treatments will need to be flexible to maximize the effects on target weed species. The anticipated treatment window for this project is June 3rd to July 31st and the Contractor must be available during that time period.

5. Requirements of Equipment to be supplied by the Contractor: Sufficient to meet specifications of the contract.

6. Loading Facilities: Use of any loading area on federal or private land, shall be arranged by and at the discretion and risk of the contractor.

7. Work Crew Requirements: Work crew for handling and mixing of chemical and loading equipment shall be furnished by the Contractor.

8. Requirements of Chemical to be supplied by the Contractor: Herbicide, surfactant, and dye shall be used and selected from the attached lists of Approved Herbicide Formulations and Approved Adjuvants for use on BLM land. Colorant/dye must be visible for 3 days after application.

9. Kind of Chemical: Picloram + Metsulfuron methyl + Dye AND Aquatic 2,4-D + Aquatic Surfactant + Dye

Contractor must provide a list of chemicals intended for use with their bid package.

10. Rate of Application:

· Terrestrial Tank Mix: Picloram (Tordon 22k or equivalent) at 16 ounces/acre (0.25 lb. ae/acre) + Metsulfuron methyl (Escort, MSM60, or equivalent) at 1 ounces/acre (0.0375lb AI/acre) + Surfactant (Rate as specified on label and compatible with herbicide) + Dye.

· Aquatic Mix: Aquatically approved 2,4-D (Alligare 2,4-D or equivalent) at 64 ounces/acre (1.9 lb. ae/acre) + Aquatically approved surfactant (Rate as specified on label and compatible with herbicide) + Dye.

11. Remarks and Other Requirements: Apply the spray solution in properly maintained and calibrated equipment capable of delivering the desired volume. Controlling drift is the responsibility of the Applicator.

The South Fork Crane weed herbicide treatment area consists of hills, mountain slopes, fan remnants, and several drainages which hold intermittent flowing streams. Terrain varies from relatively flat, 5% drainages to steep hills with 10-45% slopes. Soils are a gravelly loam. Elevation ranges from 5,600 to 6,400 feet. Vegetation consists of either a) semi-dense to dense Wyoming sagebrush and rabbitbrush shrublands with mixed perennial bunchgrasses and native forbs or, b) dense Utah juniper and pinyon pine forestlands with an understory of Wyoming sagebrush and mixed, native perennial bunchgrasses and forbs. Annual invasive grasses and annual forbs like desert Alyssum are found throughout the site. Two track roads traverse the project area.

Crane Springs borders the project area to the southwest, and in the event open water is present buffers for non-aquatically formulated herbicides to be 10 feet for application by handgun and 25 feet for application with vehicle mounted boom equipment will be followed. Spraying up to the spring water’s edge (within the buffer) will require use of aquatic formulated herbicide and surfactant.
