STATEMENT OF WORK

(SOW) Addendum 2

Invasive Species Work in

Eastern Virginia Rivers NWRC

1. GENERAL INFORMATION

1.1 Introduction. This contract addendum outlines the invasive species work controlling Chinese privet (Ligustrum sinense) on James River NWR.

At James River NWR (Prince George Co., Figure 1), our request is for the mechanical treatment of 5 acres of Chinese privet and foliar treatment of 25 acres of Chinese privet (Figure 2) .

Chinese privet treatment sites are accessible via dirt and gravel roads and require a combination of brush cutting and foliar spray of new growth. Work shall consist of furnishing all equipment, labor and materials necessary to accomplish the specified vegetative control and treatment. Spraying will take place by backpack or ATV mounted sprayer. Additional methods can be proposed to Project Officer. After spraying, the contractor will provide spatial data indicating areas sprayed, and spray application rates. There are no water sources available.

1.2 Objectives. The objectives of this project are to mechanically remove and foliar spray for new growth of Chinese privet at James River NWR.

The James River NWR requires a new growth foliar spray of 25 acres of previously cut privet and a mechanical treatment of 5 acres of a monoculture of privet at the northern part of the Refuge (Figure 2). This will be a continuation of annual treatments starting in 2020. After final contractor treatment, Refuge Staff will monitor the stand for new growth and spray with a foliar spray or hand pull.

1.3 Scope. The contractor shall furnish necessary herbicide, water and surfactant either listed below in this scope or on the Refuge Approved Herbicide List (Table 1). Any herbicide not listed on this SOW will require approval from the Project Officer prior to application. We recommend the use of an Aquaneat / Vastlan mix for Chinese privet.

For Chinese privet, mechanical removal with a chainsaw or forestry attachment can occur anytime between August 2024 and April 2025. The privet foliar spray treatment can occur anytime in July or August 2025 and will consist of an a 2:1 mix of glyphosate and triclopyr.

All herbicide applications shall be consistent with the product label instructions, manufacturer’s guidance, Refuge Pesticide Use Proposal and the requirements of this contract. Foliar spray of nontarget native species will not be tolerated.

1.4 Period of Performance. The period of performance shall be August 1, 2024 to August 31, 2025. Applications should occur in line with recommended application windows specified in Section 1.3.

2. LOCATIONS, CONTACTS

2.1 General Location. James River NWR (Figure 1). Estimated application acres, chemicals to be used, and Project Officer (project contact personnel) are as follows:

2.1.1 Locations. Chinese privet work areas are in Prince George County outside Hopewell, VA (Figure 1).

2.1.2 Acres to be treated.

These treatment units will be mapped and spatial data will be supplied to the contractor by FWS prior to application.

At James River NWR, the contractor will mechanically treat 5 acres of Chinese privet, and conduct a foliar spray on 25 acres of privet that contains the 5 acres of cut privet plus acreage treated in previous years (Figure 2).

2.1.3 Herbicide/Surfactant.

Herbicides and surfactant also referenced in Scope, section 1.3. While we highly suggest using the following herbicides, alternatives are listed in Table 1.

For Chinese privet foliar sprays: 2 and 2/3 fl. oz. of Aquaneat (glyphosate) plus 1 2/3 fl. oz. Vastlan or 2 and 1/4 fl. oz. Garlon 3A (triclopyr) herbicide per gallon of water and 1/3 fl. oz. of Kinetic or equivalent non-ionic surfactant. The contractor will apply up to 10 gallons of mixture per acre.

2.1.4. Project Officer Contact. Allie Hunter (Susan_A_Hunter@fws.gov) is the Project officer and POC for the contract. Cyrus Brame (Cyrus_brame@fws.gov; (804)586-0520) is the POC for the worksite. Both should be contacted by contractors and contracting officials.

2.2 Site Location. Treatment areas are located within the polygons depicted in Figure 2.

3. CONTROL GOALS AND HERBICIDES

3.1 General. Specific treatment areas are identified on the maps and drawings (Figure 2). The contractor is encouraged to visit the sites to determine the logistics required for the work. The purpose of this treatment is to achieve the vegetation control goals described in the next paragraph.

3.2 Vegetation Control Objectives. All of the identified unit areas will be sprayed, with each area receiving at least 95% coverage of individuals by foliar spray and 95% coverage of individual plants treated by mechanically cutting, with 95% of the targeted species killed 30 days post treatment for foliar spray. If less than 95% control is achieved, contractor will re-apply by September 15 of the next year, at their expense. The Project Officer(s) will be responsible for documenting that less than 95% of the area was effectively treated, and notifying the contractor within 45 days after the spraying activity (e.g. will survey the area, take digital photographs).

3.3 Herbicide Selection Procedure. The contractor will use “Aquaneat” glyphosate 53.8% and “Vastlan” 54.7% triclopyr mix for Chinese privet foliar spray or their chemical equivalents when similarly labeled materials are available and/or other NWR Project Officer pre-approved pesticides (Table 1). Herbicides will be appropriately labeled for specific application. No restricted use herbicides are allowed. No herbicides can be used on National Wildlife Refuge property without prior approval from the Project Officer. In addition, all carriers and adjuvants must be non-toxic as well as approved by Project Officer. The surfactant shall be added per label instructions to all herbicide mixtures.

3.4 Minimizing Impacts to Non-Target Species. All applications will be in accordance to the best management practices of the State of Virginia and federal guidelines. No broadcast spraying shall be performed when wind speeds exceed specifications listed on the herbicide label, or 10 mph, whichever is less, or wind directions are likely to result in drift to non-target areas. Broadcast spraying will occur more than 24 hours before forecasted rain event.

4. NOTIFICATION OF TREATMENT

The contractor will provide a 72-hour notice to the NWR Project Officer before arriving at the site locations for herbicide treatment work. This will avoid any conflicts with ongoing Refuge management activities and ensure that Refuge staff is available to answer questions, if required, and also to participate in any reconnaissance that may be conducted. The telephone number for the office is listed above.

5. HANDLING, MIXING, APPLICATION RATES AND METHODS

5.1 Handling and Mixing. All herbicides will be handled and stored in accordance with instructions on the EPA registration label. All herbicides shall be mixed in accordance with the label instructions so that the desired rate of application can be attained with the contractor's application equipment. Mixing water cannot be supplied at the James River NWR site and it is expected for the contractor to supply their own mixing water. The contractor is required to provide a secondary containment system around their herbicide mixing area when herbicides are mixed if mixed on government property. This containment system must be constructed of impervious materials. In addition, the contractor will ensure that no contamination of any water source occurs and that emergency spill containment equipment is at the worksite and is capable of containing all potential herbicide spills from contractor vehicles/equipment. Unused, mixed pesticides will be disposed of in accordance with local, state and EPA guidelines. Spray equipment cleaning will also be accomplished in accordance with these guidelines. Prior to leaving a worksite for the day, the contractor shall remove all equipment and unused materials, any waste materials, oil, empty herbicide containers and litter resulting from contract activities on government property.

5.2 Equipment. Required equipment includes sprayers (backpack, ATV sprayers, etc.) and necessary personal protective equipment. The equipment used by the contractor shall be designed for such work and operated in a safe manner. The equipment will be limited to function only within the patches of invasive species and adjacent roads. The equipment will be capable of accurately delivering a predetermined rate per acre dosage of herbicide and proof of calibration for broadcast sprayers. Equipment is required to be cleaned before it arrive on site to prevent the spread of invasives.

5.3 Rates and Method of Application. Application rates will be per the specification on the material safety data sheet, labeling and manufacturer's suggested rate tables, per chemical used, and the desired results identified in “3.2 Vegetation Control Objective”.
