GENERAL REQUIREMENTS TO MEET DESIRED END RESULTS FOR SUBSOILING

Subsoiling of Temp Roads, Skid Trails, and Landings in Contract Units Where Prescribed

(1) Subsoiling may be necessary to loosen compacted soils where detrimental soil conditions exceed 20 percent of the unit area or as deemed necessary by the Soil Scientist, in order to mitigate effects from harvesting, piling, masticating and/or mowing activities. Subsoiling may be used to decommission temporary roadbeds, landings, and primary skid trails. Subsoiling may not be appropriate in all instances (e.g., high surface and/or subsurface rock content, areas that are shallow to bedrock, areas where excessive damage to the root system of the residual stand may occur). Subsoiling treatment will be prioritized according to the following hierarchy to achieve the required acreages specified for each unit in Subsoiling Table below: 1) temp roads; 2) primary skid trails; 3) landings (accessible area not encumbered with slash piles), if determined to be appropriate for treatment by soil scientist and COR. Any unit requiring subsoiling treatment MUST have all temporary roads used by the purchaser treated as part of the required acreage.

(2) Recommended Subsoiling Equipment Specifications: While drafting winged subsoilers are most commonly used to achieve this work (see general description below), any subsoiling equipment/technique will be considered and evaluated as long as the definition of subsoiling below can be met. Subsoiling is often

Page 11 of 28 Bend/Fort Rock Ranger District performed with a fabricated mount on an excavator head/bucket or with a toolbar-mounted implement pulled behind a bulldozer. Equipment shanks must be capable of decompacting to a minimum soil depth of 18 inches. Implements shall be designed with adequate clearance to allow passage of smaller obstacles such as small rocks, brush, fine woody debris, and logging slash. Subsoiler design should also consider the ability to place slash to meet surface cover requirements specified below. Bulldozer-mounted implements are considered less desirable for this work due to their diminished maneuverability, greater likelihood of root system damage to the residual stand, and inability to place slash in the same pass.

(3) General Description of a Drafting Winged Subsoiler Implement: Winged subsoilers generally consist of up to four, but ideally one to two, shanks/tines up to three feet long and spaced no more than two and a half feet apart. Shanks should be beveled or equipped with a coulter blade to cut through surface and subsurface organic materials, including roots. Wings attached to the tip of each shank are generally 7 to 10 inches wide, and angled approximately 15 to 20 degrees from horizontal with the lower edge pointing in the direction of travel. Subsoilers are usually controlled using hydraulic actuation so they can be drafted to maximum depth where the wing angle is maintained through the length of the pull. Hydraulic actuation also provides the capability to maneuver the implement up and down when obstacles (rocks, stumps, etc.) need to be avoided.

(4) Definition of Subsoiling: Subsoiling is defined as alleviating heavily compacted soils using an implement specifically designed to reduce soil strength, restore intrinsic bulk density (weight per unit volume), macropore space, permeability, infiltration, and tilth of soil layers to depth. Soil shall be decompacted to a minimum of 18 inches, except where the Government agrees to lesser depths. Disturbance of surface organics and remaining vegetation will be minimized. Subsoiling results in soil that is decompacted, slightly lifted, and well-fractured both horizontally and vertically but is NOT plowed, mixed, or displaced. An implement with two or fewer shanks will generally create less plowing/mixing. Treated areas shall span the total width of the compacted ground surface. In some instances, where machine capability allows, the full width of the skid trail may not warrant treatment (e.g., decompaction of the two-track surface may be preferable). Subsurface rocks should not be pulled to the surface and large supportive roots should not be severed. The distance between subsoiler shank passes within a compacted area shall typically not exceed 24 inches unless inspection by Soil Scientist determines greater distance between passes is effective at treating compaction. Scarification may also be necessary, in addition to subsoiling, where surface soil is puddled or crusted. Subsoiling shall be kept reasonably current and shall be done during Normal Operating Season unless otherwise agreed. Subsoiling should not occur when the ground is frozen, unless approved by the soil scientist, to prevent unwanted displacement and mixing. Subsoiling should not occur during excessively dry conditions (when soils are dusty and exhibit no adherence when squeezed in a ball) to prevent destruction of soil structure and unwanted mixing. Available slash should be placed on treated areas prior to or in conjunction with subsoiling, as specified in (5) below.

(5) Slash Placement and Effective Ground Cover: To facilitate successful soil rehabilitation, subsoiling must be coupled with organic matter addition and surface soil protection. Where existing litter and fine woody material is lacking, this will be achieved by placing logging slash, woody material available within the unit, or wood shred mulch across the soil surface to achieve a minimum of 50% areal cover unless otherwise agreed to by government (this cover requirement is based on Deschutes LRMP guidance and is tied to surface soil erosion potentials derived from the Deschutes National Forest Soil Resource Inventory). If adequate slash is not present within the cutting unit adjacent to treated skid trails (within machine’s reach from skid trail or work

Page 12 of 28 Bend/Fort Rock Ranger District area), fine slash (limbs and tops with needles attached) may need to be retrieved from landing piles.

Slash/debris generated during the current activity should be targeted for application where available. No coarse woody debris of Decay Class 3 or greater should be disturbed or moved. Machines should not make additional passes off skid trails or landings solely to retrieve slash for this purpose. Subsoiling and surface cover placement should be completed in one pass, or subsoiling accomplished as the final pass, to prevent compacting or displacing treated area.

(6) Location and quantity of work: Anticipated acreage of subsoiling needed for each treatment unit is listed in the table below. However, on-the-ground work will be planned by consulting with the soil scientist or designated inspector (GTM) to determine the most appropriate areas to treat to meet soil restoration objectives. Actual acreage requiring treatment in each unit may be more or less than the amounts estimated below. Actual acres treated in each unit will be credited toward overall awarded acreage. Skid trails will be credited at 12 feet width by total length of trail treated, and temp roads will be credited at 14 feet width by total length of road treated, unless otherwise agreed to in writing.

Items 6, 14, 20, 23: Road Closures

GENERAL REQUIREMENTS TO MEET DESIRED END RESULTS FOR ROAD CLOSURES

All road closures, except for subsoil only road closures, shall include barriers that will prevent future access of the road. Barriers shall disguise the road entrance using natural materials whenever possible so as to not draw attention to the closed route. Barrier construction will include subsoiling (see specs for SUBSOILING) for 200 feet or sight distance, whichever is greater, and will also include placement of downed wood, logging slash within the immediate vicinity and/or boulders/rocks available within 15 feet of either side of the road for the entire subsoiled length. Barrier construction will extend beyond the road width if open conditions provide access around a road-width barrier.

Wherever road closure junctions fall within a subdivision OR within 1,000 linear feet of a slash pile, logging slash/small diameter material will be retrieved and placed on the road surface for the entire subsoiled length.

Barrier construction will extend beyond the road width if open conditions provide access around a road-width barrier up to 75 feet on either side of the road. Some roads to be closed have multiple junctions with open roads; all junctions will be treated in this manner and are listed in the table below.

All Subsoil Only road closures (as found on the Supplemental Map & table below) include subsoiling (see specs for SUBSOILING) for 200 feet or sight distance, whichever is greater, and will also include placement of downed wood, logging slash within the immediate vicinity and/or boulders/rocks available within 15 feet of either side of the road for the entire subsoiled length. Barriers are not required for Subsoil Only road closure service items.

10. Equipment shall not be permitted to cross meadows, stream channels, or non-work areas.

11. The Government may determine by visual observation that excessive soil displacement or compaction is resulting from the Contractor’s operations and shall direct corrective procedures. To avoid such damage, the Government may suspend operations in whole or in part as necessary.

12. Mastication or other mechanized understory treatments to reduce brush and slash shall make no more than two passes over any piece of ground when not on primary skid trails or landings.

PROTECTION OF RESOURCES

1. The Contractor will be responsible for any damage caused by their personnel and/or equipment as a result of contract activities to existing structural improvements including but not limited to fences, property line monuments, bearing trees, trend monitoring transects, road surfaces, roadblocks, water bars, drainage structures, water developments, cattle water-sets, guzzlers etc. The Contractor, at their expense, shall restore damaged property back to its original condition in a timely manner.

2. For all operations the Contractor shall furnish and place warning signs on each end of individual units that are adjacent to roads, trails, and developed recreation sites. Minimum size for the sign(s) shall be 2 foot by 2 foot.

3. No operations shall occur within invasives sites or Area’s to Protect (ATP), see Contract Area Map. For those sites on roads, the Contractor shall stay on road and no disturbance is permitted outside the width of the roadbed.

4. If any caves are encountered, do not treat within 200 feet of the cave entrance.

5. Minimize damage to recreational trails by machinery. Mow across trails and minimize turning on a trail. For other equipment, to the extent possible, cross trails with machinery at intervals no closer than 200 feet apart along the length of the trail. Crossings of recreational trails shown on the Contract Area Map shall be pre-approved by the Forest Service.

6. If any cultural or archaeological sites, any threatened or endangered species, or active raptor nests are discovered during operation of the contract, work will be suspended in the immediate vicinity of the site(s) until a reconnaissance survey is completed by the Government.

7. If any wolf dens are discovered during operations, work will be suspended within 1 mile of the site until a reconnaissance survey is completed by the Government. There are no known areas of wolf activity within 1 mile of treatment area. If new areas of wolf activity are discovered, restriction period of April 1 through July 15 would apply to den or rendezvous sites. Discovery of wolves by either the Contractor or the Forest Service, shall be reported immediately to the other party.

SECTION IV – 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 subdivisions are started, when problems are encountered and when contract work needs government oversight.

1. Each subdivision will be inspected separately. Subdivisions will not be averaged with other subdivisions for acceptance or payment.

2. When subdivisions 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) – Small Tree Treatment

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.

2. Government verification plots will consist of a series of fixed area plots on a grid to record whether density, best tree selection, and other requirements are being met and to what extent. Plots and grid will be distributed so that a representative sample is obtained.

3. The predominant density within the unit will dictate which plot size is used and only one plot size will be used within a single treatment unit. Plots and transects will be distributed so that a representative sample is obtained.

Specified Density Plot Size Plot Radius (Feet) Average Trees/Plot 50 TPA 1/10 ac 37.2 5 70 TPA 1/20 ac 26.3 3 - 4 80 TPA 1/20 ac 26.3 4

100 TPA 1/20 ac 26.3 5 120 TPA 1/20 ac 26.3 6 150 TPA 1/50 ac 16.7 3

Page 19 of 28 Bend/Fort Rock Ranger District

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 subdivision, shall be as follows:

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.

(1) At each plot, the Government will examine the plot area and record, on a Thinning Inspection Report form, findings on the items listed below: (Reference EXHIBIT A).

1) Number of trees to be left.

2) Number of trees left.

3) Number of satisfactory trees left.

4) Number of trees deficient.

5) Number of trees excess.

(a) Cut trees which are still attached at the stump will be counted as excess trees.

(b) Stumps containing live limbs which are not in accordance with specifications herein will be counted as excess trees.

(2) Work quality will be calculated on the form as follows:

No. Trees Deficient + No. Excess Trees -------------------------------------------------- = % Unsatisfactory work No. Trees to be left

100% – % Unsatisfactory work = % Work Quality

(3) Payment rate for work quality at or above 85% will be calculated as follows:

% Work Quality + 5 % Statistical Variation (SV) = % Payment rate

Page 20 of 28 Bend/Fort Rock Ranger District

(4) Examples:

(a) 2 Trees Deficient + 4 Trees Excess 6 ------------------------------------------- = --------- = 5.22% = 5% Unsatisfactory work 115 Trees to be left 115 100% – 5% = 95% Work Quality

95% + 5% (SV) = 100% Payment rate

(b) 2 Trees Deficient + 9 Trees Excess 11

------------------------------------------- = --------- = 11.96% = 12% Unsatisfactory work 92 Trees to be left 92

100% – 12% = 88% Work Quality

88% + 5% (SV) = 93% Payment rate

(c) 2 Trees Deficient + 14 Trees Excess 16 -------------------------------------------- = --------- = 16.84% = 17% Unsatisfactory work 95 Trees to be left 95

100% – 17% = 83% Work Quality - - No payment made

* If cutting to prescriptions requirements (for example: remove all cull trees) results in stocking that does not meet the desired trees per acre trees cut trees shall not be counted as deficient. Contractor shall notify COR if this is occurring regularly within any unit.

Unsatisfactory Cutting

1. If the work quality falls below 85 percent, the COR will immediately notify the Contractor, in writing, and order him to improve the quality of subsequent tree cutting. If the quality of subsequent tree cutting is not raised above the 85 percent minimum acceptable 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 90 percent as a result of excess trees, the Government may elect to do one of the following:

a) Order rework to be performed and withhold payment until excess trees are cut and the results of a post-rework Government inspection show work quality to be at least 85 percent or more. No PCT 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 Thinning Inspection Report.

3. Repeated failure to produce work quality at or above the 85 percent minimum acceptable standard will be considered reason for contract termination and default action.

Page 21 of 28 Bend/Fort Rock Ranger District

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.

Government Inspection Procedures – Treatment of Brush

1. The COR, or designated inspector, will determine compliance with treatment specifications, through 100 percent visual inspection.

2. Areas within treatment units that are not treated in accordance with specifications shall automatically require rework.

3. Only one (1) rework opportunity will be allowed, after which any unsatisfactory work will be formally inspected and may result in a reduced payment or non-payment.

4. Government verification plots for treatment of brush will consist of a series of fixed area plots along transects to record whether specifications such as percent of area treated, stem height and masticated brush depth are being met and to what extent. Treated areas that fall within the predetermined plot area will be given a rating of either satisfactory or unsatisfactory, which will provide a means to calculate percentage of satisfactory work.

Government Inspection Procedures – Slash Treatment

1. The COR or designated inspector will determine compliance of slash treatment specifications through 100

2. The COR or designated inspector will inspect lopping treatments concurrent with tree cutting.

3. For lopping, slash within treatment units, or portions thereof that is not treated in accordance with specifications shall automatically require rework as many times as necessary to conform to specifications.

4. For mechanical piling, only one (1) rework opportunity will be allowed, after which any unsatisfactory work will be formally inspected and may result in a reduced payment or non-payment.

5. For hand piling, work not in accordance with specifications shall automatically require rework as many times as necessary to conform to specifications.

6. Government verification plots for piling of slash (if necessary), will consist of a series of fixed area plots along transects to record whether piling specifications such as placement, size and compactness are being met and to what extent. Piles that fall within the predetermined plot area will be given a rating of either satisfactory or unsatisfactory, which will provide a means to calculate percentage of satisfactory work.

Page 22 of 28 Bend/Fort Rock Ranger District

7. Government verification plots for mastication/mowing small tree treatment (if necessary), will consist of a series of fixed area plots along transects to record whether depth and distribution of residual material specifications are being met and to what extent.
