PWS 1.0 Background on the Government’s Requirement United States Department of the Interior Bureau of Land Management (BLM) Mother Lode Field Office requires hazard tree mitigation and associated slash treatment work in Nevada City, CA.

PWS 2.0 General Scope of Work The project is located on approximately 20.6 acres (including reserve areas) of BLM lands near Nevada City, CA. Within the Project Area, nearly all standing conifers in both the overstory and understory have been killed by an insect mortality event and/or drought stress. All dead and dying trees will be felled and removed from the Project Area.

Place of Performance:

BLM public lands managed by the Mother Lode Field Office in Nevada City, CA in Nevada County (Township 17 North, Range 8 East, Section 22, Mount Diablo Meridian); see Technical Exhibit 3 for maps of the Project Area.

The Project Area is accessible by a 2WD motor vehicle and lowboy. The Project Area is not gated.

Traveling east on Tyler Foote Road east of Hwy 49, turn right onto Purdon Road.

Take a slight right onto Murphy Road, staying on the paved road.

Continue one-quarter (0.25) miles along Murphy Road to the north boundary of the project area.

Contract maps will be georeferenced for use with Avenza or other similar software. Work on this contract will require the Contractor to have global positioning system (GPS) capabilities to identify treatment areas and/or project boundaries.

Period of Performance:

The Period of Performance shall be for (1) Base Year of 12 months from the date of award. The Contractor shall provide to the BLM a written work progress plan that details their work force, equipment, and schedule to provide for completion of the work within the contract performance time.

Work may not occur during BLM seasonal fire restrictions without a signed variance. The Contractor must work with the BLM Mother Lode Fire staff to determine variance suitability based on environmental conditions and seasonal fire danger. Fire restrictions are generally in place between May and October; exact dates are subject to change based on environmental conditions and fire suppression resource availability.

Work performed between February 2 – September 14 (inclusive) will necessitate migratory bird surveys be performed by a qualified wildlife biologist every 14 days. Portions of the place of performance may be temporarily flagged for avoidance per the results of migratory bird surveys.

The use of heavy equipment is not permitted during periods of saturated soil conditions in the wet weather period. The wet weather period generally occurs between October 15 – May 31. Operations involving heavy equipment may occur throughout the wet weather period provided that saturated soil conditions do not exist. See Technical Exhibit 2 of this Performance Work Statement (PWS).

The place of performance in this contract contains gentle topography, with no areas exceeding 35% slope. See Technical Exhibit 2 of this PWS for information regarding reserve areas.

PWS 3.0 Overall Objective(s) The objective of this work is to safely fell standing dead and dying trees and to remove from the Project Area all resulting residues and already downed vegetative material, IAW all Specifications in this PWS.

PWS 4.0 Specific Tasks

Task 1: Contractor shall fell all dead and dying trees on BLM lands within the Project Area IAW all Specifications in this PWS.

Task 2: Contractor shall remove the entirety of all downed trees and slash, in addition to all material that has already been felled and left within the Project Area and/or any material which has fallen naturally prior to the execution of this contract, IAW all Specifications in this PWS.

TECHNICAL EXHIBIT 2: TREE AND RESIDUE REMOVAL SPECIFICATIONS AND STANDARDS (PERFORMANCE REQUIREMENTS SUMMARY)

TREE REMOVAL SPECIFICATIONS

Specifically, the project involves the implementation of the following prescription such that no dead or dying trees, or excessive residues, remain in the Project Area.

Table 2. Tree and Residue Removal Specifications and Standards (Performance Requirements Summary)

Dead and dying conifers are those with visibly fading crowns (red, brown, and/or gray needles); trees with no green needles; trees with evidence of successful bark beetle attack (i.e., exit holes on bole, pitch tubes, flaking bark); and/or snags in the beginning to advanced stages of decay. See Technical Exhibit 4 for additional information.

Treat residues from all limbs, tops, and boles. For incidental small diameter material, fuel bed depths would not exceed 4”. Total residual slash residues would not exceed 4” in depth. The Contractor shall utilize equipment capable of mechanically treating material up to and including 30” in diameter.

The preferred average piece length of all residual small diameter material is no greater than 12”.

Excess material would be hauled from the Project Area to a wood processing facility or similar destination. The Contractor assumes responsibility for the removal of all excess material from the Project Area.

All hardwood tree species (oaks, maples, madrones, etc.)

Hardwood cont.

Average fuel loading would not exceed 5 tons per acre.

The preferred average piece length of all treated and broadcast material is no greater than 12”.

Excess material would be hauled from the Project Area to a wood processing facility or similar destination. The Contractor assumes responsibility for the removal of all excess material from the Project Area.

All living, healthy conifers will be retained, regardless of species. All hardwoods will be retained, unless designated for removal by the BLM. Damage to all leave trees would be minimized to the maximum extent possible. Cut trees lodged in or covering a leave tree shall be dislodged or removed before treatment of any kind (i.e., mechanical treatment, skidding, etc.).

All residues (i.e., slash) must be removed from the Project Area IAW the Specifications in this PWS. Residues include any cut vegetation – tops, limbs, and boles – including vegetation cut prior to the execution of this contract, in addition to existing natural woody debris. Woody debris includes that which is not in contact with the ground (e.g., suspended/propped up by limbs). Residual fuels within the Project Area shall not exceed a total depth of 4”. For incidental small diameter residue, total average fuel loading shall be less than 5 tons per acre. See Technical Exhibit 5 for fuel loading photo series depicting acceptable levels of residual whole fuels within the Project Area. If there is a difference of opinion between the Contractor and the COR regarding residual fuel loading, the BLM will conduct surveys to determine actual fuel loading levels.

The Project Area is relatively flat and even; the entirety of the Project Area is accessible by tracked equipment. Trees may be felled manually and/or mechanically in areas not designated as reserve areas. Trees may be whole tree yarded to landings to facilitate mechanical treatment of limbs and tops. Where possible, the Contractor will avoid damage to residual trees. “Rub trees” may be designated as needed to avoid dispersing impacts from whole tree yarding throughout the stand. The Contractor may be asked to remove and treat “rub trees” IAW the Specifications in this PWS once skidding is completed.

Two reserve areas occur within the Project Area, totaling approximately 0.7 acres. The reserve areas will be flagged prior to implementation. Modified treatment is required within the reserve areas. No heavy equipment use is permitted within the reserve areas. Trees must be felled by hand within the reserve areas and may require the presence of a COR or a designated Government Representative. Trees occurring near the boundaries of the reserve areas would be felled away from the reserve areas to the greatest extent possible. Trees occurring near an ephemeral or intermittent stream would be felled away from the centerline of the stream. Residues would not be spread within reserve areas within 50’ of ephemeral or intermittent streams. Residues may be broadcast within reserve areas outside of the ephemeral or intermittent stream buffer zone.

The Project Area is publicly accessible for pre-site visits.

GENERAL HEAVY EQUIPMENT SPECIFICATIONS

1) Non-specialized equipment will generally be limited to slopes less than 35%. Slopes greater than 35% do not occur within the Project Area.

One additional staging area not to exceed one acre in size may be created as needed and per approval by the COR or Government Representative. New and existing staging areas must be located outside riparian zones and at least 100 feet from ephemeral or intermittent streams.

2) During loading and hauling operations, decked or piled material will be located as far as possible from roadways, communication lines, property boundaries, and living trees designated for retention.

3) All material temporarily piled or decked at staging area(s) must be removed from the Project Area prior to contract close-out. The Contractor assumes responsibility for the removal and disposal of all excess material.

LOADING AND HAULING SPECIFICATIONS

1) The Contractor may haul processed or unprocessed material to a wood processing facility or similar destination. A lump sum contract may be negotiated to facilitate removal from the Project Area.

2) All removal operations shall be restricted to the existing staging areas and, per BLM approval, one additional staging area within the Project Area. The existing staging areas are depicted on map 2 in Technical Exhibit 3 and may be expanded IAW the Specifications in this PWS.

3) Removal operations shall not result in the blocking of public traffic along any publicly accessible road for more than 30 minutes.

4) The Contractor is authorized to use County and select private roads (Lost River Road, unnamed driveway) as shown on the maps in Technical Exhibit 3 for removal of processed or unprocessed Government timber. Any road requiring improvement or renovation shall be maintained by the Contractor until receiving written acceptance of the improvement or renovation from the COR or Government Representative.

5) If the Contractor elects to use any additional private roads for the removal of Government timber or other material under the terms of this contract, they shall provide written approval for use of the private roads.

6) During hauling operations, the Contractor may be required to water daily for dust abatement during dry seasons. The Contractor shall acquire legal access to a water source to be used for this purpose.

GENERAL STANDARDS

1) Work may not occur during BLM seasonal fire restrictions without a signed variance. Fire restrictions are generally in place between May and October; exact dates are subject to change based on environmental conditions and fire suppression resource availability. Due to these restrictions, operations will generally occur during the wet weather period and must follow specified wet weather restrictions. Operations, including those involving the use of heavy equipment, generally may continue if soil and operational conditions are not causing sediment mobilization or as determined necessary by the COR. Erosion control measures may be required if operations are creating bare soil or diverting water such that sediment may be mobilized. See Wet Weather Standards below. Best practices will be used to minimize soil disturbance and sediment transport. Examples of best practices include but are not limited to slash packing ahead of tracked equipment.

2) Work performed between February 2 – September 14 (inclusive) will necessitate migratory bird surveys be performed by a qualified wildlife biologist every 14 days. Portions of the place of performance may be temporarily flagged for avoidance per the results of migratory bird surveys.

3) State Law: The Contractor shall comply with all applicable laws of the State of California. In particular, see California Public Resource Codes.

4) Permits Required: The Contractor must secure a special written permit from the Field Office Manager or designated representative before engaging in any of the activities listed below.

a) Camp, Lunch and Warming Fires.

5) Smoking and Fire Rules: Smoking shall not be permitted during fire season, except in a barren area or in an area cleared to mineral soil at least three feet in diameter. In areas closed to smoking, the CO may approve special areas to be used for smoking. These areas shall be signed by the Contractor.

a) Contractor shall post signs regarding smoking and fire rules in conspicuous places for all employees to see. Contractor's supervisory personnel shall require compliance with these rules.

b) Under no circumstances shall smoking be permitted during fire season while employees are operating light or heavy equipment or walking or working in grass and wood lands.

6) Spills: Contractor is responsible for ensuring that all equipment is in good condition and free from leaks. Contractor must ensure that each piece of equipment has necessary materials for spill cleanup. Any spill must be cleaned up promptly and reported to the COR.

7) Reporting Fires: As soon as feasible after initial control action is taken, Contractor shall notify The Bureau of Land Management of any fires within the project area whether or not the fire was a result of work performed.

8) Communications: Contractor shall furnish a serviceable telephone, radio/telephone, or radio system connecting each operation with Contractor's headquarters. A radio-equipped fire patrol person vehicle will satisfy this requirement if in operation during the time required. When such headquarters is at a location which makes communication to it clearly impractical, the BLM will accept a reasonable alternative location. The communication system shall provide prompt and reliable communications between Contractor's headquarters (or above stated alternative) and BLM. The communications system shall be operable during Contractor's operation in the fire precautionary period and at the time fire patrol person service is required.

9) Indemnification: Contractor agrees to indemnify, hold harmless, defend and protect the BLM, its officers, directors, agents and employees from and against any and all claims losses, damages, demands, liabilities, suits, costs, expenses (including attorney’s fees), penalties, judgements or obligations whatsoever for or in connection with injury (including death) or damage to any person or loss or damage of property to whomsoever belonging or pecuniary or monetary loss resulting from, arising out of or in any way related to activity conducted by or the omission of Contractor, including but not limited to Contractor’s development, construction, occupation, use operation, maintenance, and/or removal of the property, premises, of facilities, regardless of how the injury or damage was caused or suffered, unless the injury or damage resulted from the sole negligence or the intentional and willful misconduct of the BLM, its officers, directors, agents or employees.

10) Mapping/Designation: Project Area boundaries are not flagged. The Contractor is required to use project maps to stay within Project Area boundaries. All reserve areas will be flagged prior to project implementation with a yet to be determined color scheme.

WET WEATHER STANDARDS

1. All hauling (including processed and unprocessed timber, heavy equipment, etc.), construction, reconstruction, and maintenance operations on non-paved roads shall cease when precipitation is sufficient to generate overland flow off the road surface in hydrologically connected road segments. Use of the road shall not resume until such overland flow has abated and the road surface within hydrologically connected road segments do not exhibit saturated soil conditions. This rule shall not prohibit vehicles from exiting the Project Area.

1. The wet weather period is defined as occurring between October 15 and May 31, inclusive.

1. On roads that do not meet the permanent standard (see Item 5), once hauling operations have ceased during the wet weather period due to Item 1, above, they shall not resume until September 15, or the road meets the permanent standard.

1. Hauling operations during the wet weather period, in addition to complying with Item 1, above, shall cease when any of the following conditions exist:

3. When previously hydrologically disconnected road segments become hydrologically connected road segments.

3. When there is standing water within hydrologically connected road segments.

3. When equipment operation causes rutting to the extent that the ruts direct runoff from the road to discharge into a waterway; or

3. When equipment operation results in the transportation of sediment from hydrologically disconnected road segments to hydrologically connected road segments in amounts that result in a visible increase in turbidity in receiving waters.

1. When hauling operations during the wet weather period have ceased due to Item 4, above, they shall not resume until:

4. All hydrologically connected road segments have been isolated; and

4. Maintenance has corrected the condition under Item 4, which resulted in cessation of hauling, and the road meets the permanent standard.

1. When hauling operations during the wet weather period have ceased due to Item 4 above and hauling will not be resumed, then the road shall be returned to the upgraded standard as soon as practicable. If repairing damage requires heavy equipment, such that the effort will cause greater harm than good, then BLM shall treat the site with feasible effective erosion control measures as an interim measure.

1. During the wet weather period, all roads may be used by light vehicles (defined as vehicles with pay load ratings of 1 ton, or less, or smaller vehicles such as quadra-tracks or motorcycles). If such use results in road-related damage within hydrologically connected road segments to the road surface, drainage facilities, water breaks, or water crossings, the damage will be repaired using hand tools prior to the end of the workday during which the initial damage occurred. Damage shall not be to such an extent that heavy equipment will be required for repairs.

1. To prevent or minimize significant adverse effects to aquatic resources, emergency access is allowed to correct emergency, road-related problems in the form of blocked culverts, imminent road fill failure, or other erosion problems, and emergency human life situations.

1. Work sites, including roads and staging areas, will be winterized at project completion. Winterization includes: 1) grading exposed road and landing surfaces to allow water to freely drain across them without concentrating, ponding or rilling, 2) installing rolling dips/drains to drain steeper sections of road necessary to convey concentrated water across exposed road and landing surfaces, 3) clearing clogged drainage ditches or culverts, (4) using existing slash, waddles, or installing silt fences —or other erosion control devices — where needed to prevent concentration of flow and to prevent sediment from reaching stream channels or water source, and 5) spreading native brush and/or weed-free straw over bare soil to prevent surface erosion.

Table 3. Water bar spacing by gradient and erosion class

* Spacing is determined by slope distance and is the maximum allowed for the grade.
