This work consists of treating invasive plant species (noxious weeds), and providing treatment data, including geospatial files.

1. All treatments will take place within the project area boundary and associated haul routes. Treatment location priority will be as follows: 1) populations within 50ft of any road, 2) any other populations within the project area (i.e., treatment units, temp roads, landings, skid trails, haul routes, disturbed areas or other).

2. The Contractor shall treat all noxious weeds listed in Exhibit 1 (Noxious Weed Priority List), in order of priority beginning with Class A species.

3. Existing and newly established noxious weed populations:

Total 2,368

a. Existing noxious weed populations include those areas found within the project area and associated haul routes. This area has had considerable noxious weed infestations in the near past and the seed bank is likely still present so establishment in disturbed areas is highly possible.

b. Newly established noxious weed populations are those that are estimated to become established within the project area and/or near any associated haul route, post ground disturbing activities (i.e., timber harvests). These acres were estimated based on the associated temp roads, landings, haul routes and total acres found within the project area. They assume an estimated 40% reduction each year post treatment.

4. The growing season of target plants generally begins on or around June 1st of each year with the growing season ending around September 30th of any given year. Work shall commence when target plants are actively growing, and weather conditions make them most susceptible to herbicide effects as per the manufacturers’ recommendations.

a. Existing noxious weed populations will be treated for 5 consecutive growing seasons. Treatments will begin in year 1 of the project and occur pre, post and/or during other project area activities.

b. Newly established noxious weed populations will be treated for 3 consecutive growing seasons post ground disturbing activities associated with Items 1 and 2. These treatments will be in areas of ground disturbance resulting from Items 1 and 2 and will begin during the first full growing season after Items 1 and 2 are completed in an area.

5. All herbicides used within the Black Hills National Forest must have a risk assessment and worksheet as well as be approved by the State of South Dakota and Wyoming. A list of these herbicides can be viewed at the USDA Forest Service National Headquarters Forest Health protection website.

(https://www.fs.usda.gov/foresthealth/protecting-forest/integrated-pest-management/pesticide-management/pesticide-risk-assessments.shtml) Application rates and products applied to various species of noxious weeds are dependent upon species, location and stage of plant growth. Follow manufactures direction when selecting herbicide for each weed species. When working in riparian/wetlands, the Contractor shall use aquatic designated herbicides.

6. Treatment shall consist of herbicide application directly onto target plants, with little to no (less than 5% of application area) harmful effects to non-target plant species from herbicide drift. Application methods may consist of site specific application from ground-based, horse-mounted spray rigs, backpack, or motorized trucks, trailers, ATV’s and UTV’s. Any other method or treatment must be agreed to with project COR and weeds inspector. All spray equipment shall be calibrated to ensure herbicide is applied according to manufacturer’s recommended application rates. The Contractor shall comply with all South Dakota state laws, certifications and applicator licensing requirements prior to treating noxious weeds.

7. The Contractor shall provide their own water for treatment or obtain approval from the COR for any use of on-site water sources for tank mixes. Any on-site mixing will occur at least 100’ from any stream course, spring, or wetland.

8. A blue dye in the herbicide shall be used to identify location of treatments. The Contractor shall use flagging to identify weed treatment areas. This flagging will remain in place until the treatment has been inspected.

9. The Contractor will immediately notify the COR when treatments are complete each year and ready for inspection. The Contractor is required to collect geospatial data for all weed treatments and collect a separate geospatial file for all Class A & B priority species found to exist within infestations of non-priority species. Geospatial data will include attributes listed in Exhibit 2 and be compatible with ESRI software. All https://www.fs.usda.gov/foresthealth/protecting-forest/integrated-pest-management/pesticide-management/pesticide-risk-assessments.shtml https://www.fs.usda.gov/foresthealth/protecting-forest/integrated-pest-management/pesticide-management/pesticide-risk-assessments.shtml

Page 5 of 13 Northern Hills Ranger District geospatial data will be provided as polygons. Small and linear treatments may be mapped as a point or line; however, they must be converted into polygons of the correct dimensions. All weed treatments will be combined into one polygon with attributes listed in Exhibit 2. During yearly treatments, geospatial data and attributes will be submitted to the COR weekly, unless otherwise directed by the COR. All reports must be submitted by October 1st each year. Applicator spray records shall conform to South Dakota State standards.

SECTION III – INSPECTION AND ACCEPTANCE

For All Work Items:

At any point during the project, the Contractor and/or Project Manager may request (documented through email, text, or hand-written request) an in the field consultation with the Forest Service to inspect work progress, review contract specifications, or clarify issues. The Forest Service shall respond to Contractor’s request within 5 working days, excluding weekends and federal holidays.

GOVERNMENT QUALITY ASSURANCE SURVEILLANCE PLAN

Government Inspection Procedures - The COR, or a designated inspector (GTM), will make periodic inspections while work is in progress, usually daily at first, as needed to assure work is proceeding satisfactorily. The Contractor shall notify the COR when units are started, when problems are encountered and when contract work needs government oversight.

1. Each unit will be inspected as a separate unit. Unit will not be averaged with other units for acceptance or payment.

2. When units are completed and ready for government inspection, Contractor’s designated Project manager shall request unit inspection in writing, prior to moving out of the general area.

3. The COR, or designated inspector, will determine compliance with contract specifications through informal visual inspections. In the event visual inspection indicates work to be in non-compliance with specifications, prompt corrective action and/or rework shall be required.

Government Inspection Procedures – Formal (Plots)

1. In the event visual inspection indicates work and / or rework to be in non-compliance with contract specifications, a series of verification plots shall be installed by the Government to determine compliance with specifications and percent of satisfactory work for treatment of each unit not meeting specification as observed with visual inspection.

2. Government verification plots will consist of a series of fixed area plots and variable radius plots along transects to record whether density, basal area, best tree selection, and other requirements are being met and to what extent.

3. Plots and grid will be distributed so that a representative sample is obtained.

4. The COR or designated inspector will mark the center of each plot on the ground using flagging, stakes, or pin flags. Additional flagging will be hung near the plot center so that it may be seen from a distance.

The inspector will include the plot number, their initials and date on the flagging.

5. Plots will be numbered to correlate with the inspection form and transects on a unit map.

6. The minimum number of verification plots, per treatment unit, shall be as follows:

Page 6 of 13 Northern Hills Ranger District

Unit Acreage Minimum No. of Plots 1 – 9 1 plot per 2 acres 10 – 29 10 plots 30 – 59 1 plot per 4 acres 60 – 99 20 plots 100 1 plot per 5 acres

7. Determination of acceptability of the work performed will be based on Government verification inspections and will be considered conclusive.

8. Inspection plot procedures for Items 1 and 2 are described in Appendix B under C6.36# - Acceptance of Work. Plots are scored as pass or fail based on the procedures of the provision. The sum of passing plots within a unit is divided by the total number of plots for the unit. The result multiplied by 100 represents the quality of the work item within the unit.

Unsatisfactory Performance

1. If the work quality falls below AQL shown in table 1 below, the COR will immediately notify the Contractor, in writing, and order him to improve the quality of subsequent work. If the quality of subsequent work is not raised to the AQL standard within 24 business hours after receipt of such written notice, the Contractor’s right to proceed may be terminated and the contract considered in default.

2. When the work quality falls below AQL, the Government may elect to do one of the following:

(a) Order rework to be performed and withhold payment until the results of a post-rework Government inspection shows quality to be at AQL or more. No rework shall be performed unless ordered or authorized by the COR.

(b) Order that no rework be performed and payment will either be made at a reduced rate, or not at all, as determined from the Inspection Report.

3. Repeated failure to produce work quality at or above the AQL standard will be considered reason for contract termination and default action.

Reinspection Upon Contractor Request

1. If Government inspection results are unacceptable to the Contractor, a reinspection may be requested, in writing, within 5 business days after receipt of notice of said inspection results. The same inspection procedure will be used; however, the inspection pattern will be shifted so that new inspection plots will not overlap previously inspected plots.

2. If reinspection results – rounded up to the nearest whole percent – indicate a variance of more than 5 percent from the first inspection, the results of the second inspection will be used to calculate work quality and payment, and the Government will bear the cost of reinspection.

3. If reinspection results – rounded up to the nearest whole percent – are within 5 percent of the first inspection, plots from the initial inspection and the reinspection will be combined and used to calculate work quality and payment, and the Contractor shall bear the cost of reinspection.

SECTION IV – PAYMENT METHODS

Method of Measurement for Acreages

Acreages were determined by using Global Positioning Systems (GPS). Some unit boundaries are marked with paint, many boundaries are virtual.

Discernable Boundaries are locations that are readily identifiable features on the ground in locations shown on the Contract Area Map. A Geo-Fence is a location on the ground corresponding to the boundary location shown on a mobile mapping device using a Global Positioning System (GPS) Receiver using a digital vector file/shapefile. The digital vector file/shapefile will be provided as an attachment to the Contractor by the Forest Service at award. A digital list of the coordinates can be provided upon request.

Contractor is responsible for obtaining a GPS receiver(s) that is capable of determining the location of the geo-fence boundary within the contract tolerance. Allowable contract tolerance is 30 feet.

Forest Service inspection of treatment boundaries shall be conducted to determine treatments are within the allowable contract tolerance using the digital vector file/shapefile referenced above using a GPS Receiver with a minimum, tested accuracy in a Light- Medium canopy of 20 feet.

National Technology Development Program GPS Receiver accuracy reports by GPS manufacturer and model are available at: https://www.fs.usda.gov/database/gps/mtdcrept/accuracy/index.htm. Forest Service determination of boundary location will be final.

In case of a major disruption in GPS service, or lack of GPS coverage on the Contract Area beyond the control of the Contractor, as determined by the Contracting Officer, extension of time may be granted by Contracting Officer when requested in writing by Contractor in accordance with 52.212-4 (f) Excusable Delays. To resolve major disruption of GPS service, or lack of GPS coverage on the Contract Area, the Forest Service may elect to Mark Geo- Fence boundaries on the ground, in which case the Forest Service’s determination of boundary location will be final.

The acreage for each work item will be rounded to the nearest acre and is final unless:

a. The contract is modified or,

b. The Government makes a determination to remeasure or,

c. The Contractor exercises his/her option under the following Remeasurement provisions:

Remeasurement

1. The Contractor may request, in writing, remeasurement of any units under this contract if he/she feels that acreage stated on the project maps is incorrect. The remeasurement must be within the existing perimeter of the respective unit. No variance of the unit perimeters as laid out on the ground for this contract will be allowed. All requests for remeasurement must be made prior to payment for each completed unit. Remeasurement will be performed by the Government.

https://www.fs.usda.gov/database/gps/mtdcrept/accuracy/index.htm

Page 9 of 13 Northern Hills Ranger District

2. If remeasurement indicates that a variance of ten percent or less exists on units of 1 to 5 acres, five percent or less exists on units of more than five but less than 20 acres, or if three percent or less exists on units of 20 acres or larger, the Contractor shall pay for the actual costs of the remeasurement. Under this condition, payment will be made on the acreage stated on the project maps. If the remeasurement indicates the actual acreage varies by more than the above factors from that stated on the project maps, the payment will be made on the remeasured acreage and the Forest Service will pay for the cost of the remeasurement.

Acceptance and Payment – Item 2, Steep Slope Logging Cut & Skid

1. If informal visual inspection indicates acceptable work quality, the Contractor will be paid 100 percent of their bid rate.

2. In the event that formal inspections are used, the rate of payment to the Contractor will be calculated as follows:

(a) For work quality of 95 percent or higher the Contractor will be paid 100 percent of their bid rate.

(b) For work quality from 90 to 94 percent the Contractor will be paid the actual percentage multiplied by the bid rate.

(c) For work quality 89 percent and less there will be no payment made to the Contractor.

(d) If, after rework, the percentage of satisfactory work is between 90% and 94%, payment will be made by the actual percentage. If the percentage is less than 90%, the work is unacceptable, and no payment will be made.

Acceptance and Payment – Item 3, Road Reconstruction

1. If informal visual inspection indicates acceptable work quality, the Contractor will be paid 100 percent of their bid rate.

2. Only one rework opportunity will be allowed for this item.

Acceptance and Payment – Item 4, Noxious Weeds Treatments

1. If informal visual inspection verified through field inspections and spray sheet checks indicate acceptable work quality, the Contractor will be paid 100 percent of their bid rate.

2. Only “wet” acres treated counts towards target noxious weeds acres accomplished

a. Wet acres are determined by equipment calibration records for gallons/acres.

b. Acres shown in Optional Item 4 tables are yearly estimates. Payment will be made on actual wet treated acres and may vary from year to year from estimates but will not exceed the total estimated existing and newly established population acres.

3. Only one rework opportunity will be allowed for these items.

* Stewardship Credits will be earned first, whenever practical. Forest Service Funds will be used if the availability of Stewardship Credits is exhausted or if appropriated dollars are obligated to a specific item.
