Project Title Fort Pierre National Grassland Noxious Weed Treatment Contract

General Information

1.0 Background and Purpose

In alignment with the purpose of Executive Order 14225 Immediate Expansion of American Timber Production, and to ensure continuity of operations, this mission critical project is to reduce the threat of wildfire. Approximately 3,000 acres of prescribed burning was completed on the Fort Pierre National Grassland and followup is the spraying noxious weeds (especially invasive thistles) that have sprouted within the treated areas. Such follow-up is the next crucial step in fuels reduction and maintaining public support for the use of prescribed burning for fuel reduction and prairie restoration purposes.

This solicitation is for the treatment of noxious weeds in designated areas on the Fort Pierre National Grassland (FPNG), located in central South Dakota. Treatments are to be done by spot treatment application targeting thistles (Canada thistle, bull thistle, and musk thistle). The identified species will be treated during the plants’ developmental stage when optimum effectiveness can be obtained, preferably the rosette to flowering stage. Performance period for this contract is September 1, 2025 through August 31, 2026. This will allow for a fall treatment this year and if conditions do not allow, then a spring treatment can be done in 2026. Determination of when to spray will be based on agency monitoring of growing conditions and weather. All treatments will be mapped with a GPS capabile device and will be submitted to the COR within two weeks of treatment completion along with completed application records.

This contract has specific dollar amounts for areas which were burned in spring 2024 and 2025. All pastures will be grazed by cattle and may have cattle present during treatment. Potential contractors shall bid the number of actual treatment acres possible based on the specific dollar amount. The map below indicates where the burned pastures are located on the FPNG.

2.0 Definitions

ACCEPTABLE QUALITY LEVEL (AQL): The maximum allowable deviation from perfect performance that may occur before the Government will invoke payment deduction. An AQL does not allow a contractor knowingly to offer defective service, but limits reduced payment to circumstances in which defective performance results in a measurable reduction in the value of services rendered.

ACCESS TO TREATMENT AREAS: Access to treatment areas requires travel and treatment operations on or near: paved roads, graveled county roads, and non-graveled two track Forest Service roads. The treatment areas may be along or away from roads and within areas with no developed road access. Access is allowed off designated roads by authorization only issued by the Fort Pierre District Ranger. Your access must be timed such that road or trail surfaces are not subjected to unreasonable resource damage.

APPLICATION RECORDS: Records the contractor uses to document herbicide applications on the treated area. Information includes, but is not limited to: herbicide used, amount of active ingredient applied, weather conditions, etc. AQUATIC AREA: Any type of lake, pond, dam, spring, or stream course that contains an invasive plant species.

BOOM SPRAYER: Spray equipment capable of delivering a minimum of 10 gallons per acre. Boom sprayers shall be equipped with an identifier system to minimize swath overlap such as a ribbon or flagging system. ATV/UTV boom-less nozzles are not considered as boom sprayers.

CLEANUP AND DISPOSAL: Clean up and disposal of excess herbicide and empty containers is the contractor’s responsibility and will be in accordance with the manufacturer’s instructions and applicable to Federal and State Laws.

CONTRACTING OFFICER’S REPRESENTATIVE (COR): A government person appointed by the contracting officer to help the contracting officer with contract administration and surveillance.

DEFECTIVE SERVICE: A unit of service which contains one or more defects, or nonconformance with specified requirements.

GPS SPECIFICATIONS: The contractor will map treated areas using a GPS unit. Treatment areas will be collected in polygon format unless there is a single plant or an area less than 10 feet in diameter, then a point may be used. The collected data will have the treatment date and species treated in the attributes or notes section.

MIXING SITE: All mixing and rinsing during the operational period will take place in the field within the treatment areas at a distance greater than 100’ from any stream course, trees, or crops. Rinseate will be reused as spray solution as much as possible until project completion and application rates shall not exceed ¾ ounce per acre.

PERFORMANCE REQUIREMENTS SUMMARY (PRS): Identifies the key service outputs of the contract that will be evaluated by the Government to assure contract performance standards are met by the contractor.

QUALITY ASSURANCE: Those actions taken by the Government to assure services meet the requirements of the Performance Work Statement (PWS).

QUALITY ASSURANCE SURVEILLANCE PLAN (QASP): An organized written document used for quality assurance surveillance. The document contains specific methods the Government will use to perform surveillance of the contractor.

QUALITY CONTROL: Those actions taken by a contractor to control the performance of services so that they meet the requirements of the PWS.

RANDOM SAMPLING: A sampling method in which each service output in a unit has an equal chance of being selected.

SPRAY EQUIPMENT: All spray equipment shall be accurately calibrated to ensure herbicide is applied as per manufacturer recommended application rates. All spray equipment would be operated in accordance with owner’s manuals. Weed treatment accomplished by the use of spray equipment installed in trucks, ATVs, or UTVs would follow manufacturer specifications and recommendations, including those specific to weight restrictions.

WEATHER CONDITIONS: Herbicide shall not be applied if temperatures exceed 95 degrees and or the wind speed exceeds 15 mph in all areas.
