STATEMENT OF WORK

Spring Desert Herbicide Treatment

Bureau of Land Management (BLM) – Nevada Southern Nevada District Office

Background

The Bureau of Land Management (BLM) is acquiring vegetation treatment services in the Spring Desert area, an area administered by the Southern Nevada District Office (Las Vegas and Pahrump Field Offices). The work consists of applying a pre-emergent herbicide fuel break in select locations on BLM-administered lands to control and reduce the spread of invasive annual grasses, including red brome (Bromus rubens) and cheatgrass (Bromus tectorum).

Ground disturbance is not permitted due to the potential to create additional disturbance that could cause increased likelihood of spreading weeds and adverse impacts to designated critical desert tortoise habitat (Gopherus agassizii). The Contractor shall determine the appropriate application method for implementing treatments while accounting for terrain limitations and the presence of potential hazards within the project area. The Spring Desert area is a known high-risk zone for human-caused fires linked to recreational activities, where combustible invasive plant species are expanding and elevating wildfire hazards. These invaders, red brome and cheatgrass, outcompete native vegetation, degrade habitat quality, and create continuous fine fuels that facilitate rapid fire spread in the Mojave Desert ecosystem. The area is accessible to the public for recreational activities, lies along major transportation corridors, and includes sensitive environmental features such as desert tortoise habitat.

The project aims to protect and enhance critical habitat by strategically reducing hazardous fuels, controlling invasive weeds, mitigating wildfire risk to nearby communities and infrastructure, and promoting long-term ecosystem resilience and native species recovery. The project area is located along Highway 95 and Highway 160, encompassing a total of 4,814 acres needing treatment. The location of work is approximately 7 miles North of Pahrump, NV and 2 miles East of the Crystal, NV.

The project area is depicted on the Vicinity Map.

1. SCOPE

1.1 Description of Work –The contractor shall apply herbicides and adjuvants to achieve maximum control of target species, with minimal damage to non- target vegetation. The contractor shall provide all personnel, necessary management, supervision, parts, labor, materials, supplies and equipment to complete the requirements in this Statement of Work (SOW). The contractor shall be responsible for mobilization, demobilization, and cleanup.

1.2 If sensitive, endangered, or threatened species (plant or animal) are discovered within the treatment area the contractor is to immediately notify the Contracting Officer Representative (COR). The project area is within the designated critical habitat for the desert tortoise.

1.3 Period of Performance: The period of performance shall be from the date of award to

February 28, 2027. The application method to be used will only be considered during the desert tortoise inactive season (November 15, 2026 - February 28, 2027). The U.S.

Government may issue a suspension of work order and/or partially terminate any portion of the work due to discoveries of sensitive, threatened, endangered species or archeological sites during contract operations.

2. APPLICABLE DOCUMENTS AND REGULATIONS

2.1 Application of herbicides shall be in accordance with all applicable Federal, State and Local Regulations.

2.2 All herbicide treatments shall be conducted following herbicide label directions, Attachment 3

BLM Standard Operating Procedures and Mitigation Measures for Applying Herbicides, Approved BLM Pesticide Use Proposal (PUP), and all other policies and guidelines pertaining to their use. Apply herbicides in favorable weather conditions to minimize drift. For example, do not treat when winds exceed limitations, rainfall is imminent or as specified on the label.

The Government will provide the PUP to the contractor within one week of application at a pre-work meeting to be coordinated with the Project Inspector (PI) and or Contracting Officer’s Representative (COR). All herbicides and adjuvants used at the time of application must be listed on the approved project PUP.

2.3 The Contractor shall hold a current Nevada Commercial Applicator License for the application of pesticides in the weed control category appropriate for the application type.

Proof of licensing shall be provided with the quote package. All vegetation control measures shall comply with the provisions outlined in the Record of Decision for the Vegetation Treatments Using Herbicides on Bureau of Land Management Lands in 17 Western States Programmatic EIS, (September 2007 and 2016), DOI-BLM-NV-S010-2019-0053-EA Uplands Herbicide Use, and all applicable federal, state, and local regulations.

2.4 The U.S. Government reserves the right to stop treatment operations at any time when conditions are considered sufficiently unfavorable to warrant stoppage. Stoppage shall continue until operations are again authorized by the U.S. Government.

3. DEFINITIONS

3.1 Shapefile - A shapefile is a digital data storage format for storing the location, shape, and attributes of geographic features for mapping purposes commonly used in ArcGIS software.

3.2 Chemical (herbicide) treatments - Application by Commercial Pesticide Operator/Applicator, licensed by State Department of Agriculture (with Agriculture Herbicide Category), of BLM-approved herbicides (Attachment 1 Herbicides and Adjuvants) to forbs, grasses, or woody plants, as designated by the BLM, using industry standard application equipment.

3.3 Pesticide Application Record (PAR) - A legally required record of herbicide application that is filled out within 24 hours of treatment. It includes details of the application including the herbicide, rate, quantity was used, target species, dates and times of application, names of applicators, and meteorological data, etc., (See Attachment 4 Pesticide Application Record sample).

3.4 Pesticide Use Proposal (PUP) - A BLM document that summarizes the intentions of the herbicide application including targeted species, allowable herbicide rates, sensitive resources, project design features and mitigation measures for proposed projects.

3.5 Universal Transverse Mercator (UTM) - A mapping coordinate grid system based upon one of many different mapping projections. The BLM in Nevada & Arizona use the projected coordinate system UTM, Datum NAD 1983 (Conus), Zone 10 or 11. The data is displayed in meters easting and northing.

3.6 Project Inspector (PI) - This is the subject matter expert in charge of formulating the technical requirements, who coordinates and advises the COR on technical matters.

3.7 Contracting Officer Representative (COR) - The COR is responsible for technical administration of the purchase order and shall ensure proper Government surveillance of the contractor’s performance.

4. TECHNICAL REQUIREMENTS

4.1 Timing of Work- Timing of field work shall take into consideration potential target species, elevation, seasonal climate, aspect, and habitat of each project area. The contractor shall treat as many of the target plants at a given location as possible, by timing visits during the stage of plant phenological development that ensures emergence and visibility of the maximum number of plants that might be expected for that year’s treatment. In addition, the contractor shall ensure timing/phenology for treatment as directed by the product labels, to achieve maximum control over the targeted species and minimal non-target damage. The period of performance begins on the date of award to Feb 28, 2027, during the desert tortoise inactive season and while they are subterranean (November 15 through February 28). The U.S. Government’s preference is to start and complete the project as rapidly as practical, however, due to weather conditions during this time, soil moisture, soil temperature, and timeframes may need to be re-negotiated.

4.2 Access to Project Areas- For this purchase order, approximately ½ of the project will have access reasonably close that are passable by trucks needed for mixing and loading herbicide for large scale application projects (less than 3 miles). Other areas will require longer travel/ferry from mix/load operations. Some of the roads are improved graveled roads;

however, many of the roads will be improved dirt roads or two-track range roads. BLM will likely only have one staff member available to oversee and monitor the compliance of the spraying projects. The contractor shall make every effort to stage as close to the project area as possible while complying with all applicable federal, state, and local regulations and appropriate land use permitting procedures applicable to their operations.

4.3 Pre-Work Meeting -There will be a Pre-Work conference before the start of the project at an agreed-upon date between the COR/PI and the Contractor. At the pre-work conference, the Contractor shall provide the COR with a written “work progress” plan that details his/her proposed workforce and schedule to provide for the orderly completion of the work within the contract performance times. This work schedule must be acceptable to the U.S. Government.

At a minimum, the schedule should reflect a work progress rate equal to the available amount of contract performance time. The unit sequence work schedule will be determined by the COR at the prework conference but may be subject to change because of normal variations in weather conditions.

4.4 Communication Systems- The Contractor must provide a communication system so that contractor personnel engaged in the project at different locations can always communicate with each other, and so that government Project Inspectors may communicate with the contractor at any time to discuss performance matters. [DOI has adopted a policy that radios must be P25- compliant VHF-FM. Transceiver must provide selection of narrowband analog (12.5kHz) or narrowband digital (12.5kHz) operation on a minimum of 100 channels.]

4.5 Digital GPS navigation unit shall ensure straight and regular application paths. Irregular paths will result in an immediate stoppage of work. Corrective action shall be taken immediately by the contractor to ensure evenly spaced, straight, and regular paths and complete coverage of areas included in the spraying activity. The entire surface within the designated boundaries of the project area shall receive uniform coverage with herbicide except for areas excluded by the U.S. Government. Areas excluded from the herbicide operation within the designated boundaries, will not be included in the acreage computed for payment. Dispersal methods must be able to obtain proper distribution and uniform coverage of herbicide.

4.6 Application

4.6.1 The applicator shall use industry standard applications techniques. The applicator shall have the ability to uniformly deliver the designated gallons per acre (as stated in the purchase order) with a Boom/Nozzle configuration (including controlled pressure and nozzle orientation) that will provide a controlled droplet application.

4.6.2 The contractor shall apply herbicide as stated in the approved BLM PUP, minimizing over-spray and under-spray within designated boundaries. The contractor shall adjust application techniques to account for topographical features. Much of the BLM has rugged, roadless terrain, broken by box canyons, narrow valleys, steep treacherous slopes, rocky rims and juniper woodlands. The contractor shall control the spray pattern and safely and evenly apply over uneven terrain, contouring at consistent application heights and speed. The contractor shall be able to perform these services on fine scale detailed projects for sensitive projects close to private property, water or other sensitive areas.

4.6.3 The entire surface within the designated boundaries of the job area shall receive uniform coverage with the herbicide mixture except for such areas as may be excluded by the U.S. Government, including streams and other sensitive sites. Areas excluded from spraying operations within the work site boundaries shall not be included in the acreage computed for payment. Spray strips shall be distributed in such a manner as to secure a high uniformity of herbicide distribution.

4.6.4 The U.S. Government may require, at any time, that the contractor perform a demonstration that the application equipment is calibrated and will evenly distribute the designated spray at rates specified in the PUP. Checks may be achieved through a pattern test, or use of water sensitive cards at the project site. Where skips or obvious insufficient applications resulting in sublethal target species death, i.e.

striping, are documented to be >0.5% of the project area as determined from data or during on the ground inspections by the COR/PI, retreatment of the insufficiently treated area will be required at no extra cost (for labor and herbicides) to the U.S.

Government.

4.6.5 The U.S. Government reserves the right to withhold up to 10% of the purchase order application price until inspection and acceptance of the efficacy of treatment can be performed, which may occur several months after tasking has been completed. In this case, the period of performance of the purchase order would encompass the period of the herbicide treatment plus the time until inspection of the treatment efficacy can be performed, usually several months later. The contractor shall invoice for 90% of the purchase order value upon completion of tasking. Upon inspection and acceptance of the treatment efficacy at the completion of the period of performance of the purchase order, the contractor shall then submit the final invoice for the remaining unpaid balance.

4.6.6 Accuracy in application is of the utmost importance. Requirements will likely include fine-scale detailed work close to private property, cultural sites or other sensitive areas.

Contractors shall perform applications with precision in accordance with the coordinates and mapping information provided by the U.S. Government. Additional buffer strips may be designated by the U.S. Government, as a means to protect other sensitive areas.

4.6.7 The contractor shall provide data in a standard format (NAD 83 for zone 11 North in

UTM or latitudes/longitudes in decimal degrees.)

4.6.8 The U.S. Government will provide unit boundaries to the contractor in the form of shapefiles created in ArcGIS.

4.6.9 Daily PARs, referenced in Section 9 Deliverables, shall be accompanied by detailed maps (both paper and electronic) showing track lines, including daily printouts and files from the previous day. Electronic files of treatments shall be compatible with ArcGIS. A required template for the PAR will be provided by the requisite BLM field office. A sample of a PAR is provided for reference only as Attachment 4 to this SOW.

4.6.10 The contractor shall use a GPS system with an automatic shut-off system. Equipment shall be equipped with a GPS Guidance/Tracking system capable of accepting and utilizing ARC/INFO GIS Shapefiles and of directly supplying Shapefiles of treatment coverage to the U.S. Government upon completion of each treated area.

4.6.11 Herbicide shall not be applied within 100 feet (31 meters) of water sources (troughs, ponds, open water). Upland areas are non-riparian areas throughout the district and are at least 656 feet (200 meters) away from standing water. Contractor is expected to apply the herbicide consistent with the maps and shapefiles provided by the BLM.

4.6.12 Herbicide shall not be applied within ¼ of a mile for aerial application and 100 feet for ground applications, of a human residence.

4.6.13 Liquid application shall not be made during a rainstorm, snowstorm, or when the ground is frozen.
