Acceptance

The quality of the work shall be the responsibility of the Collaborator in close coordination with NPS. The Collaborator and NPS shall inspect all work often enough to ensure that the quality of the service is in compliance with the applicable specifications. Work will be accepted when it is determined by the visual inspection or plot data that the Contractor’s work conforms to the Acceptable Quality Level (AQL) for the task and critical sub-tasks.

Missed areas within the work unit will not be considered a part of the work being inspected and must be re-worked regardless of the results of the inspection of the work completed in the unit. Work units that do not comply with the Acceptable Quality Level for the task and critical subtask are un-acceptable and shall be reworked.

EXHIBIT 7. Hand Pile and Machine Pile Standards

Hand Pile Construction Standards

● Piles will be constructed in a concentric tightly compacted arrangement to ensure optimal ignition and consumption of piles during burning operation. The size of the pile may vary based on proximity of surrounding live trees and available open space. In general, all piles shall adhere to a 8’ long x 18’ wide x 6’ ht. configuration.

● As much as possible, piles will be constructed in openings, out from under live canopy cover and in areas with the least amount of grass or herbaceous cover.

● Piles with loosely compacted fuels will be “slash” cut and compressed.

● Debris extending horizontally out from piles will be linearly (vertically) cut and added to the pile, so that all debris will be consumed.

● Piles will not be constructed in, nor within 100 feet of CAs or riparian areas

Machine Pile Construction Standards (one pile per landing allowed)

Pile shall be constructed by tractor equipped with brush rake.

Piles shall be compact and reasonably free of soil.

Slash shall be bucked into lengths not exceeding 10 feet prior to piling. Material extending 3 or more feet outside the edge of the pile shall be trimmed.

Piles shall be located at a distance of at least twice their height in feet from the outer edge of tree crowns or snags.

Piles shall be no larger than 20’x20’x 8’.

EXHIBIT 8. Sawlog and Biomass Volumes by Unit, Northwest Gateway Project

The estimated quantity of wood products listed in this contract has been derived by standard procedures, Timber Cruising Handbook.

The sawlog portion was cruised using a 10% cut tree sample error. The contractor is strongly encouraged to verify volume estimates to his/her satisfaction prior to entering into a contract.

Tree Piece Required to Remove

Species Product

Merchantability of logs determined according to the National Forest Cubic Foot Scaling Handbook. “Merchantability Factor of 12.0” is equivalent to 25% gross scale (Scribner board feet).

Utilization Standards for trees and minimum pieces are shown in Exhibit 9. Salvageable products are biomass (non-sawlog) and sawlogs.

The quality, size, cut per acre, and product suitability of the timber are estimates based on detailed cruise information and weight calculations on file and available for inspection. Weight factors used are based on data collected in the region for green logs (or trees in the case of biomass). Weight data was not actually sampled on this project. Weight quantities listed herein are made available with the understanding that values shown are government estimates and are not guaranteed. For these reasons, bidders are urged to examine the contract area and make their own estimates.

This Restoration Contract is designed for mechanical harvesting with whole tree yarding; occasionally, handfelling may be necessary. This project was not planned to be logged with conventional logging equipment.

EXHIBIT 11. Wet Weather Operations (adapted from the USFS)

The Collaborator and any of their subcontractors are urged to become familiar with the below standards as the NPS will be using them extensively to assess unacceptable soil damage and to determine when to suspend operations.

This list of “Visual Indicators” is used to determine the extent and potential for machinery-caused soil compaction, puddling, and rutting. The Collaborator or their agent shall not operate equipment when ground conditions are such that excessive damage will result. Whenever there is a high risk of soil damage, as indicated by using the visual indicators in the chart or table below, operations shall be suspended until conditions improve.

Field capacity is the upper limit of the moist state. When soil moisture exceeds field capacity, the soil becomes wet and tends toward saturation; surface puddling and rutting will occur and the soil will tend to flow. The following table is a visual method for assessing soil moisture in the field without using instruments. The underlined sections indicate where the highest risk of compaction or puddling exists.

Compaction is technically assessed at 6 to 10 inches depth. Soil puddling and rutting is observed on the surface. The bold underlined soil moisture/soil texture relationships indicate a high risk of compaction, puddling, or rutting.

Upon squeezing, no free water appears on soil but wet outline of ball is left on hand.

* A ball is formed by squeezing a handful of soil very firmly.

EXHIBIT 11 (Cont.). Wet Weather Operations (adapted from the USFS)

The following information on how to recognize soil compaction and puddling problems in the field. If any of these indicators are observed, there is a very high probability that thresholds for soil compaction and puddling have been exceeded and operations shall be suspended until conditions improve.

1) Surface Indicators:

a) Skid trails have lost all slash and litter.

b) There is visible evidence of puddling, such as ruts with berms of structureless soil.

c) Water has ponded in ruts or on skid trails, indicating reduced rates of infiltration.

d) Rutting and ponding of water on main skid trails indicates that excessive soil moisture occurs on surrounding areas dedicated to growing vegetation.

e) Soil/water (mud slurry) is present and flows down skid trails.

2) Examination of Soil with Tile Spade:

a) Marked resistance to penetration with tile spade.

b) Difficulty in removing spade full of soil after spade is inserted.

c) Large volume of soil on spade (compaction increases soil strength causing the soil to resist fracturing).

3) Examination of Soil:

a) Obvious mixing of horizons or incorporation of fresh debris.

b) Most of soil volume is contained in clods rather than normal peds.

c) Soil structure is platy (natural structure is normally granular in the surface horizons and subangular blocky in the subsurface horizons). When the soil is moist, soil structure may appear to be massive rather than platy.

d) Clods have strength; can tolerate rough handling without breaking and resist efforts to break by hand when soil is dry.

e) Clods resist efforts at re-moulding when soil is moist.

f) Clods are noticeably heavy (have “heft”) as compared to normal peds.

moisture state. Moist or wet

EXHIBIT- 12. Skidtrail Waterbar Location and Construction Guideline

Prior to expected periods of precipitation and prior to skid trail restoration (see B.4.b.), erosion control work shall be kept current. If water bars are needed to protect soil resources (as determined by NPS), they will be constructed at the following specification:

● Angle of waterbar will be slope of skid trail plus five degrees.

● Waterbars will be constructed to a compacted height of 18 to 24 inches.

● Tractors will be confined to existing skid trails and equipment routes.

● Waterbars will be constructed in locations where water will be channeled freely onto undisturbed ground.

● Depth of waterbar excavation should be constructed so that the bottom of the ditch is dug six inches into undisturbed (solid) soil.

The general desired spacing is as follows:

Slope percent Erosion Hazard Rating for Area (Low) (Medium) (High) (V. High) __% Spacing ______________ ___

1 - 6 400 350 300 250 7 - 9 300 250 200 150 10 - 14 200 175 150 125 15 - 20 150 120 90 60 21 - 40 90 70 50 30 41 - 60 50 40 25 15
