Power Fire Herbicide Release Supplemental Specifications

Supplemental Specifications Herbicide Mix Specifications:

For Item 1, the herbicide mix shall contain the following:

3% glyphosate herbicide formulation

1% nonionic surfactant

0.25% purple dye

100 gallons of herbicide mixture would thus be as follows:

95.75 gal clean water

3.00 gal glyphosate herbicide formulation

1.00 gal nonionic surfactant

0.25 gal purple dye

For Items 2, 3, & 4 the herbicide mix shall contain the following:

5% glyphosate herbicide formulation

1% nonionic surfactant

0.25% purple dye

100 gallons of herbicide mixture would thus be as follows:

93.75 gal clean water

5.00 gal glyphosate herbicide formulation

1.00 gal nonionic surfactant

0.25 gal purple dye

Herbicide Application Prescription:

Apply at least the specified minimum gallons per acre of herbicide mix to target vegetation in each stand in a uniform manner that meets minimum acceptable foliar coverage as shown in attachment J.1_Exhibit_A_application_coverage. Both Minimum GPA and Application Coverage requirements must be met. If either one is not met, the Contractor may be required to retreat the stand such that both are met.

Target vegetation varies by item as follows:

Item 1: Target vegetation will be all live vegetation, woody and herbaceous, except crop trees and excluded vegetation.

Items 2, 3, & 4: Target vegetation will be all woody brush species, whether previously cut or not.

Additional application prescription elements are as follows:

“Area” = Treat all target vegetation.

“Radius – 10’ +P” = Treat all target vegetation in a 10’ radius around all crop trees and hardwoods. Where this would leave contiguous areas greater than 20’ in diameter untreated, treat all target vegetation except to leave untreated individual specimens representative of the woody brush species mix on approximately 20’ spacing, such that 90% of the total unstocked area is treated.

“Radius – 10’” = Treat all target vegetation in a 10’ radius around all crop trees and hardwoods.

“Radius – 8’” = Treat all target vegetation in an 8’ radius around all crop trees and hardwoods.

Note: All radius prescriptions will be treated as a minimum specification, meaning that any portion of the circle that measures less than the specified radius will be unacceptable. The radius will be measured from the edge of the bole, not the center.

See Supplemental Specifications Data Table below for prescription information by stand.

Protected Areas (Exclusions):

Protected Areas will be designated both inside and outside the boundaries of treatment units. Protected areas will be designated by the Contracting Officer’s personnel. They may be designated by description, by contract map, by flagging on the ground, or combination thereof. No treatment shall occur within protected areas. Contractor personnel are prohibited from entering protected areas. Protected areas include but are not limited to the following:

Streamcourses and other water features:

Designation may be by description, or with white flagging. Limited streamcourse information appears on the contract detail maps. This information may not be complete. In the event the contractor encounters undesignated water features, the contractor shall notify the Contracting Officer’s personnel immediately, and proceed to implement the standard buffer width shown below. Distances are in feet from the high water mark on each side of the channel/feature:

Streams, perennial = 100’

Streams, seasonal, wet = 50’ Streams, seasonal, dry = 25’

Streams, ephemeral, wet = 25’

Streams, ephemeral, dry = 10’

Other resource protection areas:

The contract detail maps contain known resource protection areas. Additional areas may be designated at time of treatment. Flagging colors for these protected areas include pink & black checkerboard and pink & green combinations.

Invasive Plants:

Known invasive plant populations are shown on the contract detail maps. The contractor shall avoid disturbance in these areas as much as practicable during treatment. This includes parking, staging, batching, and other concentrated activities. These are not exclusion areas. Where they occur within treatment stands, these areas shall still be treated.

Excluded Vegetation:

California black oak (Quercus kelloggii)

California hazelnut (Corylus cornuta)

California nutmeg (Torreya californica)

Elderberry (Sambucus spp.)

Canyon live oak (Quercus chrysolepis)

Pacific yew (Taxus brevifolia)

Quaking aspen (Populus tremuloides)

Western dogwood (Cornus nuttallii)

Willow (Salix spp.)
