PROJECT NAME

Gunnison Field Office Herbicide Application

LOCATION OF PROJECT

The project area is located 20 west of Gunnison Colorado on Red Creek.

CONTRACT PERIOD

Contract work must be completed between September 1, 2021 and November 1, 2021.

Site Tour

Due to the complexity of the Weeds Project, all vendors are highly encouraged to attend the hosted pre-bid on 24 June at 2:00 PM. Meet us at the intersection of highway 50 and Red

Creek Road. Be advised there is a road closure on Highway 50 between mile markers 123 –

127, so plan for a detour if coming from the west.

Location/Gunnison The purpose of this project is to chemically treat 480 acres cheatgrass on Bureau of Land

Management (BLM) ownership. The contractor will travel and treat cheatgrass within the Red

Creek area.

Much of this area has either no roads or trails or signal track trails so will be treated by backpack sprayer on foot. In the project areas there are several hundred acres of mapped cheatgrass.

The Red Creek invasive weeds treatment area is 957 acres. Out of that 957 acres 480 acres of cheatgrass are to be chemically treated. (see map).

Chemical Treatment Apply imazapic at a rate of 8oz./acre with a methylated seed oil adjuvant at a rate of 3 oz./acre.

Using ground based equipment at the previously mentioned rate with a water carrier volume of

3 to 15 gallons per acre in areas infested with cheatgrass. Dye will be mixed with herbicide for coverage marking. Apply imazapic at a rate of 4 oz/acre with a methylated seed oil adjuvant at a rate of 1.5 pints/acre using backpack sprayer, horseback sprayer, truck or ATV/UTV mounted sprayers, or other non-motorized methods targeting patches of invasive annuals. Inside the treatment area it is not continues cheatgrass, there are pockets of cheatgrass and 480 acres are to be treated inside the Red Creek treatment area.

ENVIRONMENTAL CONSIDERATIONS

1. Scheduling of all work under this contract shall be coordinated and approved between the contractor and the contracting officer representative (COR).

2. All property owners adjacent to BLM managed lands would be notified prior to any herbicide treatment.

3. A 100 foot buffer will be provided for all open water and riparian areas associated with the project areas.

4. To minimize drift, application of all herbicides will be confined to periods when wind speed is less than 5 miles per hour. Application will not occur during precipitation and sufficient drying time will be provided prior to expected precipitation.

5. To further limit the potential for damage to aquatic habitats, application equipment and calibrations (i.e. spray pressure and droplet size) must be selected to deliver sprays which minimize

1. atomized drift in situations where herbicide could potentially contact surface waters, such as stock ponds and reservoirs.

6. Only federally registered herbicides would be used.

7. The BLM Hazardous Material Coordinator would be contacted in the event there are any Hazardous Materials spills during project implementation, and hazardous materials would be cleaned up utilizing standard haz-mat procedures.

8. All appropriate label specifications will be followed.

9. All individuals associated with the handling or application of herbicides on public lands would be working under the direction of a certified pesticide applicator and would be familiar with the chemical used and emergency procedures to be used in case of herbicide spill.

10. The applicable Federal regulations concerning the storage and disposal of herbicides and herbicide containers would be followed. These are described in the EPA’s

"Regulations for Acceptance and Procedures for Disposal and Storage", Federal Register notices as amended.

SPRAYING OPERATIONS

1. The contractor shall furnish all labor, equipment and any other needed items to apply herbicide in solution to the designated areas in the time specified at their cost.

2. Spray nozzles shall be set to produce spray droplets with a median diameter of 200 microns or larger to minimize drift.

3. Contractor will supply any personnel they need to perform according to contract specifications or that they may see fit. The contractor shall have a certified pesticide applicator licensed individual on site at all times during herbicide application.

Certification must be for the use of herbicides in the Rangeland Pest Control category.

Appropriate proof of license must be submitted to the contracting officer within one week of notification of award of bid.

4. Maximum wind velocity at which spray may be applied in any treatment area is 5 miles per hour.

5. Spraying shall not be done on wet days or when rain is imminent within label rain fast guidelines or when target plant species are retaining moisture on foliage from rain, heavy dew, or frost.

6. Temperature at the time of application shall be within 45 to 85 degrees Fahrenheit.

7. The contractor shall satisfactorily complete and submit a “2021 Pesticide Application Record” (PAR) to the contracting officer within 24 hours of any application.

The BLM will also assist with getting water to designated location in the project area due to the lack of roads.

CONTRACTOR SHALL FURNISH

The contractor will provide work crews, equipment and supplies not provided by the BLM necessary to carry out contract operations including but not limited to: all herbicide

(metsulfuron-methyl herbicide or chlorsulfuron herbicide, glyphosate and all imazapic herbicide), along with a non-ionic surfactant for use with first two herbicides and methylated seed oil adjuvant for use with imazapic, and dye used for mixing to mark coverage needed for the application.

STIPULATIONS

Damage to Existing Structures Damage to fences, culverts, cattle guards, gates and other improvements will be repaired by the contractor immediately and at the Contractor’s expense. Repairs shall be made to the previous conditions as determined by the COR or the BLM will hire the work done at the Contractor’s expense.

Area achieving a work quality level of 85

– 94 percent will be paid at that percentage rate. If an Area is accepted which do not meet 85 percent, payments will be made at a rate determined by multiplying the actual inspection percentage by the bid price.
