Performance Work Statement Construct Fireline, Fuel Break and Slash Piling

Idaho Panhandle National Forests Priest Lake and Bonners Ferry Ranger Districts

1. BACKGROUND: The Idaho Panhandle National Forests (IPNF) are a jointly administered set of three national forests located in the state of Idaho that extends into the states of Montana and Washington. The mission of the Forest Service and Idaho Panhandle National Forests is to sustain the health, diversity and productivity of the Forests. In meeting this mission the IPNF has a need to construct a fireline and fuel break and to conduct slash piling in the forest in Priest Lake and Bonners Ferry, ID.

2. DESCRIPTION OF WORK: The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items necessary to construct a fireline, fuel break and associated slash piling in a manner for optimal future Forest Service burning. Perform work as defined in this Performance Work Statement. The contractor performs to the requirements in this work statement and in accordance with all applicable federal, state and local regulations and laws.

2.1 Excavator Constructed Fireline and Fuel Break:

In areas where fireline will be constructed, a continuous mineral soil line not less than 2 feet and not greater than 4 feet shall be cleared completely to expose mineral soil and placed on the outer edge of the unit. Clear all firelines of combustible material for a minimum width of 16 feet. Place material inside the cutting unit relatively free of mineral soil and scattered to minimize berm-like concentrations near the burn edge. Slash will not be buried or covered with dirt during the construction of the fireline.

The mineral soil line may not be any deeper than is necessary to expose mineral soil. When fireline is located on steep slopes, installation of waterbars may be required to mitigate erosion potential.

Spacing and the degree of angle will be designated by the COR. Install waterbars to slope to the outside of the unit with no residual materials blocking any potential flow of water. Place material produced from scraping down to mineral soils on the outside of the line/unit.

2.2 Construct Fuel Breaks generally not less than 10 feet and no greater than a width of 20 feet and remove all combustible material to break the continuity of the fuel bed. The width of the fuel break can vary, based on types and amounts of fuels on the ground, and will be coordinated with the COR (average 16 feet). Place material cleared in the fuel break construction on a designated side of the fuel break. Material shall be free of mineral soil, and scattered to avoid concentrations greater than 2 feet in height. Acceptable equipment for fireline and fuel break construction is an excavator equipped with an approved bucket and thumb. If the Contractor proposes to use other equipment, it must be coordinated with and acceptable to the COR prior to accessing the site and start of work.

2.3 Fireline and Fuel Break Construction Work Categories:

Each unit where fireline and a fuel break is to be constructed has been assigned (by the Forest Service) a ‘work category’, as shown on the Price Schedule and as described below, categorizing the difficulty of operations based on factors such as slash load, slope, and need for erosion barriers. As these factors vary across the forest and unit by unit, the assigned categories help determine the workload needed to meet objectives.

Category 1 per Mile Slope: 0-25%, Minimal erosion barriers required. Line location is reasonably free of slash requiring minimal scattering or throwback.

Category 2 per Mile Slope: 26-45%, Erosion barriers required. Line location contains moderate amounts of slash requiring throwback or side scattering.

Category 3 per Mile Slope: 46% + numerous erosion barriers required.

Throwback and scattering is not emphasized in this category because of slope constraints.

2.4 Excavator Piling:

The work objective is to gather and pile slash and debris meeting the following description for “Material to be Piled” in such manner that will provide for complete and unattended combustion of the piles with relatively minor effort of ignition. This work may occur on slopes up to 45% and on rocky terrain.

Some of the worksites have portions of ground that will be declared unpliable due to excessively steep slopes, wet or rocky surfaces, or light fuel loadings. Piles will have no significant quantities of soil mixed with material that would impede free combustion. The size classes of material to be piled, the approximate dimensions of the piles and the approximate percentages of material to be piled and to be left laying on the worksites are as described. The work will be performed to accomplish the following objectives:

(1) Material to be Piled: Material will be predominantly burnable organic matter with a minimum of soil content. Logging slash, uprooted brush in specified areas, and excessive concentrations of organic, burnable material shall be piled in order to enhance the site for hand tree planting or natural regeneration and to effectively reduce the fuel hazard.

Material in the 0” – 7.0” diameter size class will be piled. Approximately 65% - 75% of the entire work area should have this size material eliminated.

(2) Pile Requirements: Material must be placed into piles of sufficient height so that piles will ignite readily and burn up completely. Slash will be aligned in the same direction as much as possible. Emphasis will be placed upon pile compaction and height will be emphasized over pile width because high, well-compacted piles ignite readily and burn up completely. Slash must be tightly pressed into piles as opposed to loosely arranged in order to support complete combustion. Minimum pile height is 6 feet. Past experience indicates that a ratio of two vertical feet to three horizontal feet results in piles with optimal burning capability. For example, a pile 6 feet in height should be 9 feet wide or a pile 12 feet in height should be 18 feet wide. This is 1 of the guidelines to be used in determining a pile’s acceptability. In areas of units that contain a minimum of slash, piles can be made smaller than the specifications indicated with the approval of the COR. Small piles that are placed close to one another will not be accepted; consolidation of Piles will be required.

(3) Windrows: Slash is pre-sawed into short lengths, so the placement of material into long windrows will not be necessary or acceptable. Operators can expect material to be sawed into 10-12 ft. lengths (with the exception of Category 4). Sale area purchaser or USFS crews will buck material prior to piling. Contractor will not be required to perform any sawing.

(4) Long-Term Nutrient Recycling: Approximately 10 tons to the acre of woody material will be left on dry habitat types (Northern Prairie Unit #90), and approximately 20 tons per acre for moist habitat types (Placer Nuggets Units #29 and #36 and Nickelplate Units 81, 110, 112, 114, 115). Unsound, decomposing pieces are preferred over sound pieces. The tons per acre are subject to change at the discretion of the COR. In order to avoid excessive maneuvering, it is acceptable to leave isolated pockets of slash and debris. This will also apply to areas where there is not enough slash to make an acceptable pile.

(5) Ground Scarification: The percentage of ground surface to be scarified will not exceed

40% of the total unit surface area. The objective will be to create a favorable germinating and growing environment that will ensure a higher percentage of tree survivability by reducing the surface competition with other herbaceous material. In addition, it is desirable that the scarification process provide a mineral soil growing environment that is mostly devoid of mixtures of surface litter and duff.

(6) Resource Damage: Resource damage must be minimized at all times. Damage to delicate soil compositions, creation of erosion potential, and consistent scarring of seed trees and standing adjacent timber will not be acceptable. Soil erosion must be eliminated by providing adequate erosion barriers within the area of activity. Operating on excessively wet, saturated soil will be avoided. The work shall be done when the soil moisture is less than 25%.

Locate piles as far away from designated leave trees as feasible--a minimum of 15 feet where possible to accommodate future Forest Service burning procedures. The expectation is to have a minimum of 5 feet from the dripline to prevent canopy scorch. Locate piles at least 10 feet from unit boundaries adjacent to Forest Service land and 20 feet from unit boundaries adjacent to private land. Retain all standing trees in an undamaged condition.

Areas identified as roads shall be kept clear of contractor created slash piles from the top of the cut back to the downhill edge of the fill. Slash piles will not be permitted on road surfaces. No slash may be left within 5 feet of culverts, nor on trails, roads or fill-slope after piling. Keep Contractor equipment tracts parallel to the road surface in areas where roadside piling is required. Any damage to road surface, cut, or fill slope must be repaired prior to Forest Service acceptance of the work.

Each unit to be machine piled has been assigned (by the Forest Service) a ‘work category’, as shown on the Price Schedule and as described below, categorizing the difficulty of piling operations based on factors such as amount of existing slash, slope, and tree denisty. As these factors vary across the forest and unit by unit, the assigned categories help determine the workload needed to meet objectives.

Category 1 35-50 tons per acre Slope 0-35%, Tree density tends to be moderately open with some restrictive swing movement. Some decisions are required by the operator concerning where best to build slash piles

Category 2 Standing tree density tends to be more restrictive (than category 1) and machine maneuvering becomes more time consuming, but slope and fuel loading are the same as Category 1

OR:

Standing tree density tends to be moderately open with some restrictive swing movement and slope averages are 0-35% (same as category1), but the fuel loading seems to be somewhat heavier than 35-50 tons per acre.

Category 3 Heavy fuel loading: 50 plus tons per acre Slope 0-35% plus Dense standing tree conditions that require careful machine travel and swing movement. Operator is required to monitor pile placement closely in order to avoid crown and stem scorch.

Category 4 Slope 0-40% plus In these units, slashing of damaged or suppressed trees and bucking to the standard lengths is almost non-existent.
