SPECIFICATION T-804 SURFACING REPAIR

1.1 Surfacing repair is repairing potholes or small soft areas in the Traveled Way. It includes area preparation and furnishing and placing all necessary Materials, and other work necessary to repair the surface.

MATERIALS

2.1 Material used in the repair of soft areas on aggregate or native surfaced roads may be acquired from approved commercial sources, Forest Service Borrow areas shown on Contract Area Map, or Borrow sources agreed to. The quality and quantity of the imported Material used in the repair will be limited to that needed to provide a stable

Traveled Way for hauling and to minimize damage to the road and adjacent resources. The quantity of imported surface repair Material used in the appraisal estimate will be shown on Road Maintenance Plan. However, the magnitude of the work may vary depending on Contractor’s hauling schedule and ground conditions.

2.2 Material used in the repair of bituminous pavements may be acquired from local commercial sources. If a mixing table is required, the location shall be approved by the Forest Service. The bituminous mixture to be used by the Contractor shall be approved by the Forest Service. The Contractor’s share of the quantity of bituminous mixture used in the appraisal estimate will be shown on Road Maintenance Plan. However, Contractor's share of the work may vary depending on Contractor's hauling schedule, ground conditions, other traffic, etc.

3.1 Work under this specification shall be performed in a timely manner to reduce further deterioration of the

Traveled Way.

3.2 Soft spots on aggregate or native surfaces shall be repaired by placing the imported Surface Course on top of the soft spot. Layers of imported Material shall be placed until a firm surface is produced.

3.3 Bituminous Pavement Repairs. The areas to receive bituminous pavement repairs will be marked on the road surface by the Forest Service just prior to Contractor performing the work.

3.4 Potholes (deep patch). Surface Course and Base Course Materials shall be excavated to a depth necessary to reach firm, suitable Material. The minimum depth of excavation shall be 2 inches and the maximum depth of excavation shall be to the top of the Subgrade.

The edges of the prepared hole shall be extended to form a vertical face in unfractured asphalt surfacing. The prepared hole shall generally be circular or rectangular in shape, dry, and cleaned of all loose Material.

Prepared potholes shall be patched or barricaded immediately.

The faces of the prepared hole shall be tacked with a slow-setting emulsified asphalt.

The bituminous mixture shall be placed in layers not exceeding a compacted depth of 2 inches. Each layer shall be compacted thoroughly with hand or mechanical tampers or rollers. Compaction shall not be done with equipment wheels.

AG-9AC7-S-14-0131 Appendix C PAGE 9 of 22

SPECIFICATION T-806 DUST ABATEMENT

1.1 This work shall consist of preparing Traveled Way and furnishing and applying Materials to abate dust.

MATERIALS

2.1 The roads requiring dust abatement, type of dust abatement Material to be used, the rates of application, and frequency of applications will be shown on Dust Abatement Plan. The Dust Abatement Plan may be changed by written Agreement.

2.2 Water. The locations of Water Sources are shown on Contract Area Map.

Operating Guidelines:

1. Operations are restricted to one hour after sunrise to one hour before sunset.

2. Pumping rate shall not exceed 350 gallons per minute.

3. The pumping rate shall not exceed ten percent of the stream flow.

4. Seek streams and pools where water is deep and flowing, as opposed to streams with low flow and small isolated pools.

5. Pumping shall be terminated when the tank is full. The effect of single pumping operations, or multiple pumping operations at the same location, shall not result in obvious draw-down of either upstream or downstream pools.

6. Each pumping operations shall use a fish screen. The screen face should be oriented parallel to flow for best screening performance. The screen shall be designed and used such that it can be submerged with at least one-screen-geight clearance above and below the screen.

7. Operators shall keep a log on the truck containing the following information:

a. Operator’s Name

b. Date

c. Time

d. Pump Rate

e. Filling Time

f. Screen Cleaned (Y or N)

g. Screen condition

h. Comments

Screen Construction Criteria:

1. Surface Area:

a. The total (unobstructed) surface area of the screen shall be at least 2.5 square feet, based on the upper limit of pumping of 350 gpm. Larger surface areas are recommended where debris buildup is anticipated, and where stream depth is adequate to keep the screen submerged at approximately middepth.

2. Screen Mesh:

a. Screen Mesh must be in good repair and present a sealed, positive barrier effectively preventing entry of the “design fish” into the intake. The design fish in this case is an immature (20-30mm) salmon or steelhead fry.

b. The screen mesh size shall be: round openings – maximum 3/32 inch diameter (.09 inch)

c. Square openings – maximum 3/32 inch diagonal (.09 inch)

d. Slotted openings – maximum 1/16 inch width (.07 inch)

AG-9AC7-S-14-0131 Appendix C PAGE 10 of 22

3. Screen Design:

a. Water drafting screens maybe off-the-shelf products, but they are often custom-made devices appropriate to the scale and duration of pumping operation. To keep the screen supported and correctly positioned in the water column, adjustable support legs are advised. Screen geometry can be configured either as rectangular or cylindrical, e.e. as a shallow “box-shape” or tubular.

b. The intake structure shall be designed to promote uniform velocity distribution at all external mesh surfaces. This can be accomplished with a simple internal baffle devise that distributes the flow evenly across the entire surface of the screen. In order to accomplish this, the designer needs to understand the hydraulic characteristics of these devices. There is a tendency for most of the intake water to enter the screen near the hose end, so a typical internal baffle would consist of a pipe (or manifolded set of pipes) which have variable porosity holes at predetermine spacing. We recommend starting near the hose end with approximately 5 – 10% average open area, and gradually increasing the porisity toward the length of the sceen. At a point where screen length exceeds three times the diameter of the suction hose, the baffling effect tends to diminish rapidly.

At this point the baffle porosity may approach 100%. A successful baffle system will functionally distribute flow to all areas of the screen. A poorly designed screen may result in high-velocity “hot spots”, which could lead to fish impingement on the screen face.

c. Hydraulic testing of prototype screen designs is recommended where the application is on-going and extensive.

4. Screen Structure:

a. The screen frame must be strong enough to withstand the hydraulic forces it will experience.

However, the structural frames, braces, and other elements that block the flow, change flow direction, or otherwise decrease the screen surface area should be minimized.

5. Screen Cleaning:

a. The screen shall be cleaned as often as necessary to prevent approach velocity from exceeding 0.33 feet per second. Operators should withdraw the screen and clean it after each use, or as necessary to keep screen face free of debris. Pumping should stop of screen cleaning when approximately fifteen percent or more of the screen area is occluded by debris. A suitable brush shall be on board the truck for this cleaning operation.

b. If the operator notes (1) impingement of any juvenile fissh on the screen face or (2) entrainment of any fish through the screen mesh, he/she should stop operations and notify the Department of Fish

& Game and/or NMFS hydraulic engineering staff:

3.1 General. Dust abatement Materials shall be applied to the road surface as necessary to control road surface loss, provide for road user safety, and minimize damage to adjacent resources.

3.2 Compaction. When the methods listed below specify compaction, Traveled Way shall be compacted by an 8 to 10 ton pneumatic, steel-wheeled or equivalent vibrating roller making 2 passes over the full Traveled Way and

Shoulder width, unless compaction is not required on the Dust Abatement Plan.

3.3 Preparation to Dust Abatement Materials Other Than Water. The following applies to all methods of preparation:

Bituminous residue shall be scarified and pulverized to produce loosened Material not exceeding 4 inches in greatest dimension.

Traveled Way shall be bladed in accordance with T-803.

Prior to applying DO-6BA, DO-6PA, or DO-8, the top 2 inches of Traveled Way shall contain not less than 80 percent nor more than 120 percent of optimum moisture as determined by AASHTO T-99, Method C. Prior to applying other bituminous Material, Traveled Way shall have a moisture content between 1 and 3 percent.

If surface dusting prevents the bituminous Material from penetrating, a light application of water shall be applied just prior to applying the bituminous Material.

Lignin Sulfonate and magnesium chloride shall be applied when the top 1 inch of Traveled Way contains not less than 3 percent moisture, nor more than 120 percent of optimum moisture as determined by AASHTO T-99, Method C.

Moisture content will be determined in accordance with AASHTO T-217 OR T-239.

One or more of the following methods shall be used, as specified in the Dust Abatement Plan.

Method 1. Compact Traveled Way and apply the dust abatement Material.

Method 2. Develop a layer of loose Material approximately 1 inch in depth for the full width of Traveled Way.

Apply the dust abatement Material to this loose Material and compact after penetration. If traffic makes maintenance of the loose Material difficult, 1 inch of the Material may be bladed into a windrow along the

Shoulder. The specified moisture content shall be maintained in the windrow and the top 1 inch of Traveled Way.

The windrow shall be bladed to a uniform Material. When the dust abatement Material has penetrated, Traveled

Way shall be compacted.

Method 3. Blade 1 inch of Material from Traveled Way into a windrow along the Shoulder. Maintain the specified moisture content in the windrow and the top inch of Traveled Way. Apply half the dust abatement

Material. When the dust abatement Material has penetrated, the windrow shall be bladed to a uniform depth across dust abatement Traveled Way, and the remaining dust abatement Material shall be applied. Traveled Way shall be compacted.

Method 4. Develop a layer of loose Material approximately 2 inches in depth for the full width of Traveled Way.

Apply half the dust abatement Material to the loose Material. Blade the top 2 inches into a windrow along the

Shoulder. Apply the remaining dust abatement Material to Traveled Way and the Berm. Spread the Berm evenly across Traveled Way and compact.

AG-9AC7-S-14-0131 Appendix C PAGE 12 of 22

WET WEATHER OPERATION STANDARDS

(05/16/02)

Project Clause - Use of Roads by Contractor, states in part "...Contractor is authorized to use existing National

Forest roads...when such use will not cause damage to the roads or National Forest resources and when hauling can be done safely." Clause titled Operating Schedule and Erosion Prevention and Control state in part Contractor’s operations may be conducted outside Normal Operating Season (October 16 through May 14, inclusive).

Logging operations may be conducted outside the Normal Operating Season (NOS), however, certain requirements must be met in order to have operations proceed during this period. Compliance with pertinent Best Management

Practices (BMPs) by the Contractor is necessary to meet water quality requirements as agreed to between the State of California and the US Forest Service. The following standards are intended to further clarify Project requirements by providing specific criteria for conducting sale operations during wet weather conditions and to facilitate consistent implementation across the Klamath National Forest.

The following guidelines are to be used to determine if conditions are favorable for wet weather/winter operations and to provide guidance as to when conditions warrant suspension of operations, when operations may begin or resume, or when and what remedies may be appropriate. These guidelines also apply within the Normal Operating

Season (NOS—May 15 through October 15) when prolonged periods of wet weather are encountered. These standards were developed to protect water quality. Protection measures for other resources and facilities, such soils and transportation system, are addressed in the Project and other Forest Service standards and guides.

A. General Guidelines:

* Operations will be continually monitored by the Contractor and the Forest Service, including: sale administration personnel, Contractor representatives, and resource specialists. Conditions may change as operations progress during the wet season. If detrimental effects to the transportation system, water quality, or soil resources are encountered by either party, immediate notification of designated sale administrative personnel by either the

Contractor or Forest Service shall occur. The Contractor and Forest Service will work together to develop actions necessary to alleviate these effects.

* BMP guidelines dictate that no sediment/contaminant flow into stream courses from any facility used by the

Contractor, including B. Roads, C. Skid Trails, Cableways, or Harvest Areas, D. Landings, and E. Fueling

Locations, will be permitted at any time. BMP measurable thresholds, listed in paragraph “2)” under the major headings below (BMP indicators that operations should be curtailed and/or corrective actions implemented), warn the Contractor and the Forest Service that BMP violations are possible if action is not taken. Expression of any of these BMP indicators does not necessarily indicate BMP violation(s) and degradation of water quality has occurred.

B. Roads:

General - Hauling/Access Use:

* Required road work for prehaul must be accomplished prior to the wet season or periods of precipitation.

Saturated road surfaces should not be graded. At least 2" of snow should remain on the road surface after snow plowing. Road surfaces must be at a standard and maintenance level that will support the impacts of wet weather operations. This includes the following:

1) Actions that augment BMP compliance:

Wet Conditions

AG-9AC7-S-14-0131 Appendix C PAGE 18 of 22

* Drainage structures and erosion/sediment prevention actions will be in place and functioning prior to expected precipitation events.

* Roads will be properly graded and ditched or outsloped.

* Portions of roads that lie within Streamside Management Zones (SMZs) and road locations where eroded material is likely to enter channels will be rocked to Forest Service specifications and geotextile fabric used when appropriate, unless otherwise agreed, with input from a resource specialist and an engineer.

* Operations will be scheduled to use roads in order to avoid the risk of rutting during "precipitation events."

* By agreement, use of the variable tire pressure option can be used to reduce surface replacement and will reduce Contractor road maintenance costs.

Snow Conditions

* Snow will be removed without disturbing the road surface, cut bank, fill slope, or drainage structures. No soil or aggregate should be intermixed with the sidecast snow during plowing or grading. At least 2" of snow should remain on the road surface after snow plowing.

* Snow berms must be breached, except in sensitive areas, to allow proper road drainage. These outlets must be spaced so as not to concentrate road surface flows (usually spaced no more than 200 feet apart). Erosion control structures (straw bales or filter fence) may be required at the outlets to collect road generated sediment.

Frozen Conditions

* If the road surface freezes, the road surface segments must remain completely frozen and must be able to support the weight of any vehicle that will be driven on it. If the road thaws, see below...

* When any part of the active road length thaws and mitigations, such as rocking, cannot be implemented to ensure water quality protection, the road will not be used. This will preclude the use of the road by all vehicles (including administrative) unless the activity can be restricted to that portion of the road that remains frozen.

2) BMP indicators that operations should be curtailed and/or corrective action implemented:

CULVERTS:

[1] Sediment and/or debris is blocking 30% of inlet or outlet.

[2] More than 10% of the flow passes beneath or around culvert, or noticeable piping erosion evident, unless crossing is designed to do so (e.g., coarse material rock fill)

EROSION:

[3] Scour and/or sediment deposition evident, and extending more than 20 feet below outlet of cross drain or other drainage structure (e.g., culvert, rolling dip, waterbar).

[4] Scour &/or sediment movement into SMZ or drainageway from road surface, cut slope, or fill slope.

AG-9AC7-S-14-0131 Appendix C PAGE 19 of 22

[5] Material sidecast within 25 feet of a channel, ditch or drainageway, or onto slopes vegetated for erosion control.

PONDING:

[6] Ponding present on road surface that is causing fill subsidence or otherwise threatening integrity of fill.

RUTS/RILLS:

[7] More than 10% of road segment length has rills or ruts more than 2 inches deep and 20 feet in length which continue off road surface, with potential to deliver sediment to stream channel.

[8] Ruts formed that can channel water past erosion control structures.

[9] Numerous rills present at stream crossing (>1 rill per lineal 5 ft), apparently active or enlarging, evidence of some sediment delivery to stream.

3) Operating Requirements & Remedies:

* If more than 10 percent of the road segment length is rutted 2 inches in depth or greater, Contractors use of the road will be suspended. (Percentage will be determined in one mile increments if road is longer than one mile). If the road is to remain closed, it must have a barrier of some type installed to keep out all vehicular traffic and signed to keep traffic off road surface.

* If the roadway dries and can support vehicles without causing rutting, soil displacement, damage to drainage structures, and with no off-site sediment movement, it can be used. If not, it should remain unused.

* Roads damaged by Contractor's Operations and associated damage will be repaired at the Contractor's expense. A remedy plan will be prepared and implemented. Repair work shall be accomplished immediately when conditions are such that additional damage to the resources will not occur or when designated by the Forest Service.

Native Surfaced Roads and Other Roads Identified for Special Hauling Requirements

* The native surfaced roads and other roads listed below are located in sensitive soils that are prone to road surface damage during wet weather use. There shall be no log hauling on these roads during precipitation events. The timber sale operator shall allow an adequate drying period after a rain occurrence prior to resumption of hauling (normally 1 day depending on soil type and/or as determined by Contractor and Forest

Service Rep.).

Road Number Termini - Termini

N/A

Rocking Roads

* Locations where road rocking is required to harden the road surface for wet weather haul will be designated in writing and flagged on-the-ground by the Engineering Rep. or Sale Administrator. Minimum depth of rock that meets engineering specifications will be established in writing and inspected by the Forest

Service prior to use of the road for hauling outside the NOS.

AG-9AC7-S-14-0131 Appendix C PAGE 20 of 22

C. Skid Trails/Cableways/Harvest Areas:

Skid trails will be flagged by the Contractor and approved by the Forest Service in advance of falling.

General

* No more than 15% of the activity area (includes temporary roads, landings, skid trails, and cableways

[cable corridors]) should be subjected to detrimental ground-disturbing activities. Ground-disturbing activities produce adverse changes in soil porosity (compaction), soil cover, and soil organic matter.

Snow/Frozen Conditions

* Snow can act as a cushion to to protect wet soils. Unless otherwise agreed, within the operating area, a minimum of 6 inches of machine compacted snow with a minimum water content of 2 inches is required for over-the-snow logging or the soil should be frozen to a depth of 6 inches for logging operations to occur

(frozen soil occurs primarily on the Goosenest District). When the snow depth approaches this minimum, snow conditions must be monitored on a daily basis to verify snow depth is sufficient to start or continue operations. Approval to operate on snow less than indicated above must include an evaluation by a soil scientist or hydrologist. At least 90% of the skidding surfaces must meet the above snow cover standard at all times. If snow cover falls below 90%, see section 2) below for "bare ground" standards.

Wet Conditions

Skyline - No Specified pre-conditions.

Cut-to-Length System - Processing of material on the designated skid trails by a harvester may occur when soils are dry to a depth of 4 inches. Limit harvester to 1 or 2 passes over the same piece of ground. The forwarder will stay on designated skid trails covered with a minimum of 6 inches of slash.

Feller/Buncher System - Movement of material to the designated skid trails by a track laying feller/buncher may occur when soils are dry to a depth 4 inches. Feller/buncher will be limited to 1 or 2 passes over the same piece of ground. Skidding equipment will stay on designated skid trails until soils are dry to a depth of 10 inches.

Traditional Tractor Logging - Skidding may occur by conventional high-ground-pressure equipment when soils are dry to a depth of 4 inches. Equipment is restricted to the designated skid trails. Endlining will be used to move material to the designated skid trails until soils are dry to a depth of 10 inches. Equipment may, by agreement, leave designated skid trails when soils are dry to a depth of 10 inches.

2) BMP indicators that operations should be curtailed and/or corrective actions implemented:

[10] More than 20% of skid trail or cableway surface lengths have rills present that are over 2 inches deep and more than 10 feet in length.

[11] More than 10% of skid trail surface length has ruts greater than 2 inches deep.

AG-9AC7-S-14-0131 Appendix C PAGE 21 of 22

[12] Rills and/or sediment deposition extends more than 20 feet below waterbar outlet.

[13] More than 10% of waterbars fail to divert flow off skid trails or cableways.

[14] Erosion within or sediment movement into SMZ.

[15] Presence of gullies (erosional features greater than 4" deep and 6" wide).

* Skid trails, cableways and harvest areas damaged by Contractor's Operations and associated damage will be repaired at the Contractor's expense. A remedy plan will be prepared and implemented. Repair work shall be accomplished immediately when conditions are such that additional damage to the resources will not occur or when designated by the Forest Service. See the Wet Weather Operation Field Guide for a list of potential remedies.

D. Landings:

Landings will be agreed to by Contractor and designated sale administrative personnel prior to their construction and/or use. Landings will not be located within SMZs or Riparian Reserves unless a resource specialist (hydrologist, geologist, fisheries biologist) is consulted.

* Landings will be constructed to ensure proper drainage, compaction and stability. Landings will be monitored to ensure that drainage is effective. For example, landings will not create a depression which cannot be properly drained; upslope runoff will be diverted, to an appropriate location, around the activity.

* If rocking is required for wet weather operations, landings should be rocked before the surface becomes saturated.

* Landings should be identified well in advance of logging activities. This would allow construction be complete within the NOS. But if unavoidable and as a preventative measure, all landing fill slopes constructed outside of the Normal Operating Period should be mulched. Mulch material can consist of wood chips, certified weed-free straw, or any other Forest Service approved material which will provide slope protection against erosion and rilling. In addition, downslope perimeter erosion control will be required if a potential threat to water quality exists as determined by an earth scientist.

* The use of a heel boom loader may be required to minimize landing size and reduce excavation of the site.

2) BMP indicators that operations should be curtailed and/or corrective actions implemented:

[16] Rills (greater than 1/2" deep and 10' in length) and/or sediment deposition has extended more than 20 feet below the toe of the landing fill slope.

[17] More than 1 cubic yard of material (from erosion or slope failure) has moved into SMZ.

AG-9AC7-S-14-0131 Appendix C PAGE 22 of 22

* Landings damaged by Contractor's Operations and associated damage will be repaired at the Contractor's expense. Repair work shall be accomplished immediately when conditions are such that additional damage to the resources will not occur or when designated by the Forest Service.

E. Fueling Sites:

1) Action that augment BMP compliance:

* Contractor shall take additional appropriate measures documented in a wet weather fuel storage plan to prevent any oil or oil product spill from entering any stream or drainageway.

2) BMP indicators that operations should be curtailed and/or corrective measures implemented:

[18] Evidence of more than 10 gallons of fuel or oil products outside bermed containment area.

* Fueling sites damaged by Contractor's Operations and associated damage will be repaired at the

Contractor's expense. Repair work shall be accomplished immediately when conditions are such that additional damage to the resources will not occur or when designated by the Forest Service.

Forest Service retains the authority to suspend any or all of Contractor's operations as needed to protect resources.
