About this file
This is a Detailed Specifications document for herbicide application services on approximately 2,498 acres near Tuscarora, Nevada. The contractor must treat target noxious weed species including hoary cress, Scotch thistle, and spotted knapweed across two distinct treatment areas: 2,425 acres of upland terrain requiring a terrestrial tank mix, and 73 acres with potential water presence requiring a water's edge tank mix. The work site is located in T40N, R51E and T39N, R51E, with performance estimated between May 18th and June 19th, 2026. The contractor must supply all equipment, chemicals, surfactants, dyes, and work crew, and is responsible for restoring any damage to public or private access roads to their original condition.
Chemical specifications require the terrestrial mix to contain 2,4-D at 32 ounces/acre combined with Chlorsulfuron at 1 ounce/acre, non-ionic surfactant, and visible dye, while the water's edge mix requires water-approved 2,4-D formulations at up to 64 ounces/acre with approved surfactant and dye. All chemicals must be selected from BLM-approved herbicide and adjuvant lists, with the contractor providing a chemical list prior to the pre-work conference. Critical operational constraints include a 6pm-9am restriction on mobilization and application until after May 15th due to sage grouse habitat value, mandatory 0.25-mile buffers around any flushed sage grouse with backpack-only application permitted within 0.25-0.5-mile buffers, and 10-foot or 25-foot buffers from water depending on application method. All spray equipment must be properly maintained and calibrated, with the contractor responsible for controlling drift.

DETAILED SPECIFICATIONS
HERBICIDE APPLICATION
2026 Tuscarora Herbicide Weed Treatment
1. Target Species: Hoary Cress, Scotch thistle, and spotted knapweed Additional noxious weed species found within the designated contract boundary, and susceptible to chemical intended for use, will also be treated.
2. Treatment Area: A total of 2,498 acres including: 2,425 acres of upland where no water will be present and therefore will require the terrestrial tank mix, and 73 acres that have the potential for water to be present and will require the use of the water’s edge tank mix. Treatment areas vary in the density 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 0.5 miles outside of Tuscarora, Nevada. Legal description of the treatment area: T40N, R51E and T39N, R51E. 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 18th to June 19th, 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: 2,4-D + Chlorsulfuron + non-ionic surfactant + dye AND up to water’s edge approved 2,4-D + up to water’s edge approved non-ionic surfactant+ dye
Contractor must provide a list of chemicals intended for use prior to pre-work conference.
10. Rate of Application:
· Terrestrial Mix: 2,4-D at 32 ounces/acre (0.95 lb. ae/acre) + Chlorsulfuron at 1 ounces/acre (0.0375lb AI/acre) + non-ionic surfactant (Rate as specified on label and compatible with herbicide) + dye.
· Water’s edge tank mix: Up to water’s edge approved 2,4-D (Alligare 2,4-D or equivalent) at 64 ounces/acre (1.9 lb. ae/acre) + up to water’s edge approved non-ionic 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.
Due to the high sage grouse value of the treatment area, mobilization to or from the site, and application of chemical will not occur between 6pm and 9am until after May 15th. In the event a sage grouse is flushed on site the contractor must apply a 0.25-mile buffer around the area where the sage grouse was observed for the duration of the performance schedule. No application will occur within that 0.25 buffer; backpack application only is allowed within the 0.25-0.5-mile buffer around the area where the sage grouse was observed.
If 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 herbicide formulation and surfactant.
