HERBICIDE APPLICATION

2021 O’Neil Herbicide Weed Treatment

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

2. Treatment Area: 2,624 acres including up to approximately 76 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 5 to 45 miles southeast t of Jackpot, NV. The Legal Description for the treatment area is: T47N R65E,T47N R67E, T47N R68E, T47N R69E, T47N R70E, T46N R64E,T46N R65E, T46N R67E, T46N R68E, T46N R69E, T46N R70E, T45N R64E, T45N R65E, T45N R67E, T45N R68E, T45N R69E, T45N R70E, T44N R63E, T44N R64E, T44N R65E, T44N R66E, T44N R67E, T44N R68E, T44N R69E, T44N R70E, T43N R63E, T43N R64E, T43N R65E, T43N R66E, T43N R67E, T43N R68E, T43N R69E, T43N R70E, T42N R68E, T42N R69E, 42N R70E & T41N R69E. 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 in order to maximize the effects on target weed species. The anticipated treatment window for this project is May 17 to June 17 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.

10. Rate of Application:

· Terrestrial Tank Mix: Picloram (Tordon 22k, or equivalent) at 32 ounces/acre (0.5 lb ae/acre equivalent) + Metsulfuron Methyl (Escort XP or equivalent) at 1 ounce/acre (0.0375 lb ae/acre equivalent).

· 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.

Quote must include both tank mixes. Only one terrestrial tank mix will be selected and funded, based on price and Government application needs.

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 O’Neil herbicide weed treatment area consists predominately roadside application. To the best of the Government’s knowledge known access issues related to private landowner permissions or washed-out roads were avoided. However, the Government cannot guarantee additional issues may not arise due to previously undocumented or changing conditions (i.e. fire activity, previously unreported washouts, or overgrown roads) and access restrictions (i.e. locked gates), especially in the “checkerboard ownership” areas. Even if access is limited, contractor is expected to travel these areas for treatment. Terrain varies from relatively flat 2-5% slope to rolling hills ranging from 10-30% slope. Soils are a shallow clay loam. Elevation ranges from 5800 to 6600 feet. Vegetation consists of dense patches of Utah Juniper, Wyoming sage, and mountain big sagebrush. Mixed perennial bunchgrasses, native forbs, annual invasive grasses and forbs are widespread throughout. Portions of the contract area have recent burned so dense patches of downed/burnt Utah Juniper are also present.

For areas where water is present during the time of application, the buffers for non-aquatically formulated herbicides will be maintained at 10 feet for application by handgun and 25 feet for application with boom equipment. Spraying up to the water’s edge (within the buffer) will require use of aquatic formulated herbicide and surfactant.
