PROJECT WFM-0811-17FHF

INVASIVE SPECIES CONTROL IN THE LINVILLE GORGE AREA OF THE PISGAH NATIONAL FOREST: INVASIVE PLANT SPECIALIST Specifications for Contractor Treating Dobson Knob Area (will generally, but not in all cases, apply to other treatment crews as well – NCDENR and Job Corps) Contractor shall furnish all labor, supervision, and transportation, and perform all work required to perform control treatment on National Forest land in accordance with the specifications and provisions contained herein. Also, the Contractor shall furnish all materials, equipment, tools, and supplies needed except herbicide, surfactant, dye, and oil which will be supplied by the Grandfather District Mixmaster on the Pisgah National Forest. The areas to be treated are located in the Dobson Knob area of the Linville Gorge Area. See the attached site maps detailing roads and areas for invasive species control. All contract map locations are approximate; therefore, actual locations designated on the ground take precedence over the contract maps. The contractor will complete all treatment work during the period specified.

The species known or suspected to occur within the Linville Gorge area, including Dobson Knob, are given in the table below. While a complete invasive survey has not been completed across Dobson Knob, Paulownia is known to be the most common species based on recent reconnaissance and disturbances, in particular the 2007 wildfire. Previous Paulownia assessments within this area and across similar landforms in the Shortoff Mountain area recorded densities varying from 1-20% cover per acre. Except for Microstegium vimineum and Lonicera japonica, any of the remaining species listed in Table 1 will be treated if encountered. Few infestations of these other species are anticipated across the Dobson Knob area.

Table 1. Documented or potential non-native invasive plant species in the Linville Gorge Area.

Herbicide Application, Technical Specifications and Safety

Method of herbicide application will be a combination of the following:

· Foliar Application: spraying the plant foliage directly

· Cut Surface Application : cutting stem of vegetation and spraying or painting herbicide mixture on the cut surface

· Basal Bark Application: spraying a herbicide mixture on the lower part of the woody stem. National Forests in North Carolina Staff will serve as the point of contact when determining which application method is best for questionable situations (it is unlikely that this will be used given the time frame of the contract, but it is listed here as a possibility).

Technical specifications for herbicide treatment are as follows:

· Target plants to be treated by cut stump method - Any plant with a woody stem; plants may be treated up to the edge of surface water.

· Target plants to be treated by foliar spray method - Plants that are less than 8 feet high Plants may be treated up to the edge of surface water.

· Target plants to be treated by basal bark method - Woody stems that are at least 30 feet away from surface water; Woody stems that are no more than 6” diameter at ground level Application Method Procedures

· Cut Stump Method - Cut stems within 12 inches of ground level with loppers, handsaw, pruners or chainsaw. The stump will be sprayed, or painted, with the herbicide mixture within one minute after the cut. Air temperature must be above 40°F. No treatment will occur during periods of rainfall or while stems are wet. Herbicide mixture for this treatment will be a 50% mixture of Garlon 3A (or equivalent) herbicide in water with a dye added.

· Foliar Method - Leaves will be sprayed with the herbicide mixture until they are mostly wet, but not to the point that the herbicide mixture is running off the leaves and dripping on the ground. Spraying will be accomplished with a pump-up, compression sprayer. Air temperature must be above 65°F. No treatment will occur during periods of rainfall or while foliage is still wet. Herbicide mixture for this treatment will be a 4% mixture of Garlon 3A (or equivalent) herbicide plus 0.5% non-ionic surfactant in water, with a dye added. Garlon 3A will be utilized for control of all the targeted species except for Chinese silvergrass, Chinese yam, and privet. A 4-10% glyphosate solution will be utilized for these species.

· Basal Bark Method - This method will be used only when directed by US Forest Service Personnel or designated contractors. Spray the basal portions of the target plant, including the root collar, so that the lower 12 inches of the plant is thoroughly wet, but not to the point of runoff. Spraying will be accomplished with a pump-up, compression sprayer. No treatment will occur during periods of rainfall, while foliage is still wet, or the ground is frozen. Herbicide mixture for this treatment will be a 20% mixture of Garlon 4 (or equivalent) herbicide mixed with JBL Oil (or equivalent), with dye added. Seedlings and juveniles of targeted species can be mechanically removed (hand or weed wrench) within the 30 foot zone around surface water.

Mixing, Supply and Transport of Herbicides

· Herbicide will be supplied to the Contractor at the work site or a mutually agreed location. The Contractor shall give at least 2 working days advance notice to the COR prior to picking up the herbicide. Sufficient supplies of herbicide will be made available to the Contractor for work on weekends and holidays.

· At the pre-work conference, or when herbicides are initially issued to the Contractor, the mixmaster or COR will furnish a packet to the Contractor containing pesticide labels and material safety data sheets for the herbicides and adjuvant being used. The Contractor and crew shall become familiar with the contents of the packet and its location in case of an emergency.

· The Contractor shall use every precaution necessary to prevent pollution of streams by fuel, oils, herbicides, silt, or other harmful material. Application equipment will be filled and cleaned inside or adjacent to the treatment areas and at least 100 feet from private land and/or 30 feet from flowing streams.

· The contractor is legally responsible for the safe transportation of herbicides. Contractor shall follow travel routes designated by the COR when transporting herbicides from the public road system to the treatment sites. Transport vehicles shall be parked inside the treatment site or in an area designated by the COR.

· Transportation of herbicides used on this contract shall be in accordance with label instructions and the general approved and accepted procedures for safe transportation of herbicides. The following precautions should be taken by the Contractor to prevent spills, accidents, injury or theft:

1) Transport herbicides in the cargo compartment of a truck or other vehicle away from the passenger compartment.

2) No personnel should ride in the back of a vehicle with the herbicide.

3) All herbicide containers should be tied down or otherwise constrained to prevent breakage or spillage.

4) Pesticides should not be transported in the same compartment with food or clothing.

5) If any herbicide is spilled in-or-from the vehicle it should be cleaned up at once.

6) Unlocked herbicides should not be left unattended.

· Contractor shall be responsible for all costs of damages, clean-up, and decontamination should a herbicide spill occur. If a spill occurs, every effort will be made to keep it from contaminating water and other off-site areas. The spill shall be cleaned-up as quickly as possible. Appropriate Federal, State and local officials will be notified. Herbicide spills shall be handled in accordance with the standard procedures for spill clean-up. (40 CFR 117) COR shall be notified immediately of any herbicide spill or accident.

· Handling and application of Herbicides: Personnel handling herbicides should wear protective clothing and/or equipment as recommended by the herbicide manufacturer. Herbicide shall not be applied or equipment cleaned outside of areas designated by COR. Following these simple rules will help make the use of the herbicide safer for everyone:

1) Read the safety information on the label.

2) Wear the proper protective clothing.

3) Keep first aid equipment and supply of clean water readily available, including soap and eye wash equipment meeting OSHA regulations.

4) If at all possible, do not work alone.

5) Keep the container below eye level when pouring to avoid splashing or spilling any herbicide on the face or into the eyes.

7) If herbicides are spilled, stop immediately, wash out eyes if contaminated and remove contaminated clothing. Wash the skin thoroughly with soap and water. Speed is essential. Once clean, put on clean protective clothing and equipment and clean up the spill. See a physician as appropriate.

8) Keep measuring cups and other equipment clean and properly stored when not in use.

9) Wash hands carefully before relieving yourself, eating, or smoking.

· Herbicides used on this contract will not be stored or left overnight except at storage facilities approved by the COR or mixmaster. Unused herbicides will be returned to the storage facility at the end of each work day or kept in a secure location approved by the COR or mixmaster. All empty containers shall be returned to the storage facility at the Forest Service Workcenter for disposal by the Forest Service. No empty containers will be left at the worksite.

Quality Control The contractor will GPS the boundaries of areas that have been treated on a daily basis. A field log will be kept of work accomplishments. Within each area treated and GPS’ed, the contractor will estimate the percent cover by species treated. GPS data and field data copies will be sent (electronically) to the COR or to the Project Coordinator/Inspector on a weekly basis.

The Contractor will maintain an accurate daily treatment log of work activities and chemicals applied in treatment areas with a copy made available to FS at billing or upon request. The daily log must record the following:

· Date

· Name of licensed commercial applicator (first and last name)

· Names of other licensed applicators and noncertified applicators

· Time of day (start time and stop time based on a military clock)

· Treatment location

· Approximate acres treated (actual extent in acres of pesticide application)

· Treatment method/equipment used
