Statement of Work

Herbicide Application

I. GENERAL INFORMATION

The US Fish and Wildlife Service (Service) is seeking a contractor to chemically treat common reed, Phragmites australis in targeted management units at Back Bay NWR. Work shall consist of furnishing all necessary chemicals, equipment, labor, water (carrier), insurance and supervision necessary to accomplish the specified vegetative control measures by means of application. Similar contracts are being advertised for Great

II. LOCATION AND CONTACT

A. Location:

i. TOC: Lauren Mowbray, 4005 Sandpiper Road, Virginia Beach, VA 23456, lauren_mowbray@fws.gov, 703-919-1728.

ii. General Location: 100 acres including variety of non-tidal fresh/brackish emergent wetlands, shrub/scrub habitat, saltmarsh vegetation, and maritime forest. Phragmites may be found sporadically in clumps (polygons) within each unit. The entire units are not infested and we do not want uniform spray throughout the polygons. We are looking for targeted applications to the clumps only to decrease non-target effects. The Refuge may provide detail through in-person meetings and revised digital GIS maps to the Contractor prior to application.

III. TREATMENT DESCRIPTION

A. Project Time Frame: While preferred to be completed in 2025, we would extend this contract to

2026 if not able to complete in 2025 I. Preferred spray window: May 1-31; Second Choice spray window: August 15-September 30

B. Herbicide/Surfactant for late season spray: Contractor shall apply the herbicide that best controls Phragmites; this herbicide includes a mixture of water, Habitat (or their chemical equivalents when similarly labeled materials are available from multiple suppliers and approved by the NWR Project Officer) and Methylated Seed Oil (MSO), at the rate of 4 pints (64 oz.)

Habitat + 1 qt. MSO, per acre, or as per latest manufacturer requirements.

IV. EQUIPMENT, HERBICIDE, AND PERSONAL PROTECTIVE EQUIPMENT

Contractors/work crews will provide the necessary equipment and supplies. Herbicides, including mixing and application equipment will be brought by contractors. These materials will be applied, handled, and always labeled properly. Temporary storage of appropriately labeled excess pesticides will be permitted at refuge storage facilities. All herbicide and herbicide equipment must be removed prior to completion of the contract. Decontamination site does not exist on refuge property and must be handled by the contractor off site for post operations clean-up. All personnel involved in the use of pesticides will have formal training and utilize the PPE recommended by the pesticide label.

The Contractor and on-site personnel shall be able to identify Phragmites australis in all stages of development and be knowledgeable about methodologies to minimize non-target impacts.

Personnel providing technical work should be on-site at least once per management unit with their staff to provide instruction and supervision.

The Service uses Pesticide Use Proposals (PUPs) to document pesticide use and to help ensure we select and use pesticides with the least risk to non-target resources while still achieving pest management objectives. Due to site characteristics (soils, groundwater table), Regional review is needed.

Recommended general use pesticides: Glyphosate and Imazapyr Use surfactants that are practically non-toxic or have slight acute toxicity (LC50 >10 mg/L (ppm)) to aquatic organisms when applying pesticides. Surfactants that fulfill the criteria include but are not limited to: Agri-Dex, Breeze, Dyne-Amic, Level 7, LI-700, Hasten EA, Inter-Lock, Modified Vegetable Oil, MSO, NIS-EA, Rainier-EA, Superb HC.

All persons applying herbicide must have valid pesticide applicator license from State of Virginia, and must wear appropriate protective PPE, both for herbicide use and for heavy equipment use.

All equipment will be washed (following the best management practices (BMP) for washing described at http://dnr.wi.gov/topic/Wetlands/documents/WetlandInvasiveBMP.pdf prior to arriving at refuge and prior to leaving any site to avoid cross contamination of the habitats.

The Contractor is liable for the safety and health of its employees. The Contractor is responsible for the correct application of pesticides and chemicals according to EPA and State labels. The Contractor shall keep commercial application records in accordance with state and federal requirements.

IX. CONSTRAINTS

The Contractor shall ensure all equipment moved onto Refuge land is free of soil, seeds, vegetative matter and other debris that could contain or hold noxious weeds or seeds. Due to the sensitive nature of soils, only low-pressure equipment should be used for treatment. Due to challenging, site-specific field conditions and limited access, ground application IS NOT possible and will not be considered as an acceptable method for herbicide application.

The Contractor shall coordinate access and treatment activities with the Refuge.

X. DELIVERABLES

In addition to the applicable requirements, the Contractor shall provide the following deliverables and reports:

Contractor will provide maps of the polygons treated within two weeks of final application.

Contractor will provide AgNav data files with treatment maps, within two weeks of final application.

Report summarizing effort, timing, amount and mixture of herbicides used, effectiveness of treatment, and any recommended follow-up treatments.

The Contractor must coordinate closely with project manager on scheduling of work and must be flexible to accommodate optimal treatment window and weather. Contractor will notify Refuge staff in writing of expected visits to the Refuge with minimum notice of 2 business days.

The Contractor shall bring problems or potential problems affecting performance to the attention of the Project Manager as soon as possible. Verbal reports will be followed up with written reports when directed by the Project Manager.

XI. PERFORMANCE STANDARD

Accurate daily application records will be maintained by the Contractor.

Performance Evaluation. The Project Manager will evaluate performance of Contractor through monitoring of treatment during and after work performance and through review of documents.

Acceptable Quality Level (AQL).

The Contractor shall complete 95% of the treated areas within the specified dates.

The Contractor shall follow the quality control plan submitted as part of their quote.

The Contractor shall follow EPA labels and supplemental labels with no deviation. Additional reduction in chemical use may be required by the Refuge based on historic effectiveness.

The Contractor’s daily commercial application record shall be accurate and maintained with no deviation.

Contractor will not treat areas with backpack spray, ATV or other ground equipment.

a. Vegetation Control Objectives:

A minimum of 90% of all of the identified infestations to be treated in the treatment areas will be sprayed with each infestation receiving at least 90% coverage by foliar spray, to the degree that at least 90% of the live stems yellow prematurely within 2-3 weeks of the spray, or contractor will re-apply late summer/fall the very next year, at his/her expense. The Refuge Project Officer will be responsible for documenting that less than 90% of the area was treated, and notifying the contractor, as soon as possible after the herbicide activity (e.g. will survey the area, take digital photographs).

b. Herbicide Selection Procedure:

Herbicide, to be supplied by the Contractor, (Imazapyr based herbicide, Nufarm Polaris EPA Reg.

No. 288-534 or BASF Arsenal EPA Reg. No. 241-299) and surfactant (Methylated seed oil).

Herbicides must be registered for aquatic use and approved by the Refuge 60 days prior to application. No restricted use herbicides are allowed. No herbicides can be used on Refuge property without prior approval from the Refuge Project Officer. In addition, all carriers and adjuvants must be non-toxic and registered for water applications. If other herbicide is suggested, this herbicide must be vetted by the TOCs for use on their respective refuges and offered at least 2 weeks lead time prior to treatment to assess the herbicide.

c. Minimizing Impacts to Non-Target Species: No broadcast application shall be performed when wind speeds exceed specifications listed on the herbicide label, or 10 mph, whichever is greater, or wind directions are likely to result in drift to non-target areas, or public use areas. There will be zero tolerance for direct spray or drift of herbicides into non-target vegetation or on adjacent property. No broadcast application shall be performed if more than 10% chance of rain is forecast for the day of application or for 24-hour period following the planned application.
