Project Title R9 Superior National Forest, Laurentian District Mechanical Site Prep FY2025

General Information

1.0 Background and Purpose

This contract requires site preparation in compliance with its terms, specifications, and provisions.

It is the intent of this contract to secure site preparation services required for the Superior National Forest, Laurentian Ranger District for year 2025. The Contractor shall furnish all labor, equipment, supervision, transportation, supplies, and incidentals to perform all work necessary for site preparation.

Also, due to the nature of the work and the unknowns that may be encountered, changes in acreage of units shown in Schedule of Items can be expected. After reviewing alternate areas with the Contractor, the Contracting Officer's Representative (COR) reserves the right to substitute, at the contract price, the same type and amount of work in other areas similar in topography and conditions within the Ranger District boundaries shown on the maps in lieu of the original areas when it is determined by the COR that the original areas or portions thereof are unsuitable or unavailable for performance of the specified work. Equipment movement of more than 5 miles from the nearest boundary of the original area to the substitute areas will be paid for at rates mutually agreed upon between the Parties.

LOCATIONS AND DESCRIPTIONS

All map units are on the Laurentian Ranger District, Aurora, MN.

Schedule of Items and map packet will show project location, access to map units, plus supplemental information.

Most units have road access; however, some locations may have limited access and/or require snow plowing. Roads will be County roads, Forest Service specified, or temporary roads. Temporary roads may need to be opened before site preparation treatments can begin and shall be reclosed for the unit to be accepted by the COR (see more in Road Use and Maintenance).

2.0 Definitions

DBH (diameter at breast height) - Diameter of the trunk of the tree measured at 4.5 feet above the ground level on the uphill side of the tree.

Dry soil season - When the ground is dry and will not easily rut. If dry soil season is required, work without dry soil conditions must be approved by the COR before any operations can begin. Generally, the normal dry period is between July 1 and September 15.

Leave tree -Any tree that is required to be left standing as provided in the specifications (same as a reserve tree).

Merchantable tree - For this site prep contract, a merchantable tree is equal to or greater than 5 inches DBH.

Post-harvest Units - These sites have been logged and have varying amounts of standing overstory trees. Some sites may also contain these standing overstory trees as orange painted reserve trees. Site boundaries are marked with painted boundary trees or flagging. These units are typically full planted or seeded, and it is generally expected that the entire unit will be treated unless it is determined to be inoperable as agreed upon with the COR.

Reserve area - An area designated to be left undisturbed, typically identified on the ground with flagging or painted trees or identified on attached maps

Scarify - Scraping the ground surface to expose mineral soil by moving leaf litter and woody debris.

Slash - Limbs and trunks of downed trees.

Snags - Standing dead trees.

Workable Areas - Workable refers to areas where the ground can be manipulated to the desired result. Workable areas are typically less than 35% slope. In post-harvest units, the workable area is typically the harvested area.

Workable areas exclude:

· Reserve areas and any updated map areas identified during the prework meeting.

· Areas described in General Specifications and Resource Protection

· Streams, rock outcrops, and non-forested wetlands, and small low/wet inclusions.

· Unforeseen areas found by the contractor during the performance of work and agreed upon with the COR. (For example – areas that expose rock and unforeseen shallow areas)

Unworked areas that are one acre or larger will be deducted from payment. Acres will not be replaced if dropped for operability reasons, unless approved by the COR.

Contractor Requirements

3.0 Technical Requirements / Tasks

TASKS AND CRITICAL SUB TASKS

This part of the contract identifies the critical tasks and subtasks required in the contract. It also specifies the quality standard of each task and related subtask, as well as the acceptable quality level for each task and related subtask, the means of measuring the level of quality and any penalties or incentives associated with the level of quality.

Each time a new operator starts on this contract, at the job site immediately prior to the start of operations, the Contractor or his designated foreman shall discuss the following specifications with operators:

· Work Methods

· General Specifications

· Road Use and Maintenance

· Resource Protection

· Special Considerations

WORK METHODS

Contractor's operations must proceed in an orderly manner to facilitate prework equipment inspections (as described in Deliverables/Schedule 4.0). Unless approved otherwise by the COR, the Contractor will restrict operations to one site at a time. The Contractor must notify the COR 48 hours prior to moving the Contractor's crew to work on another District.

The Contractor shall provide equipment that is suitable for the job. Machine operators and assistants and other key personnel shall be required to comply with all Federal, State and Local codes.

GENERAL SPECIFICATIONS

The Contractor shall adhere to the following specifications for all site prep work unless there are specific supplemental project specifications:

Rock Raking Mechanically scarify sites and pile slash with a dozer or crawler tractor with a rock rake blade as specified below.

Objectives of these treatments are to scarify the ground to expose mineral soil and control competing vegetation. On average, rock rake teeth will work the soil to a depth of 4-8 inches. Scarify the area to provide an adequate seed bed or planting spots.

Mineral soils will be exposed but organic matter will not be scraped outside of unit and can be displaced no more than 50 feet from origin. Avoid displacement of shallow soil where more than 36 square feet of continuous exposure of rock or clay surface occurs. Avoid uprooting of mature tree stumps from previously harvested timber.

Equipment used for the mechanical site prep shall be equipped with a Forest Service approved spark arrestor, safety canopy and a serviceable fire extinguisher.

The dozer or crawler type tractor will be equipped with a rock rake blade that is capable of piling slash, brush and sprouts. There should be at least 8 teeth, more than 12 inches long on the rock rake blade. Rock rake blade must be in good working condition. A rock rake blade in good condition will have rake teeth at least 50% or more of their original height. Teeth with less than 50% of their original height will be replaced.

The teeth of the rock rake blade should run to a minimum depth of 4 inches and a maximum of 8 inches beneath the surface of the ground to allow for mixing of organic and mineral soil. Target soil depth may be adjusted on a “per unit” basis by the COR.

Quality Standard: 100% of workable area is effectively treated.

Compacting/Crushing of Fuels Mechanically crush woody materials with a dozer or crawler tractor. Dead or alive Balsam Fir less than 5 inches DBH will be the primary targeted fuels for compacting/crushing. Crushing or damaging non-targeted tree species less than 5 inches DBH shall be avoided, but may be permitted by the COR when necessary to access areas of targeted fuels.

Fuels shall be crushed to lengths less than 15 feet. Fuels are to be flattened in a way that no branches reach a height of 36 inches from the ground.

Tree species that are designated as protected by the COR are not permitted to be crushed or subsequently damaged. Avoid crushing fuels on designated trails, roads, or outside of the unit boundary.

The task of compacting/crushing of fuels shall be accomplished before or during the task of rock raking. Therefore, the targeted fuels and all crushed woody materials shall be piled in the same manner as slash.

Quality Standard: 100% of workable area is effectively treated.

Slash The preferred method of dealing with slash is to have multiple small piles across the site, instead of having a few very large piles.

Piles will be scattered evenly across the site and will be no greater than 15 feet in diameter on the soil surface unless agreed upon by the COR. Piles shall be less than twice as wide as they are tall.

Piles will be less than 10% dirt and rock. Piles should be able to be burnt cleanly and thoroughly. The COR may require the operator to roll the pile over to remove excess dirt and rock. All areas between the piles will be treated.

Piles shall be no closer than 50 feet from any road, trail or work unit boundary. No piles shall be made within 25 feet of merchantable trees, standing snags, or clumps of standing timber. In visually sensitive areas such as locations with recreation use nearby, piles will not be allowed without COR approval.

Quality Standard: Piles are 15 feet in diameter or smaller. Piles are less than 10% dirt and rock.

Leave Trees Live trees with a diameter of 5 inches or larger will be left standing unless necessary to provide access, ensure operability, or for operator safety. In these situations, cutting live trees 5 inches and larger must be pre-approved by the COR.

Any tree with a painted band will be left standing. No trees marked with paint or flagging shall be cut or knocked over. The goal is to have 100% of painted trees left, but 95-100% is acceptable.

5-foot no-treat buffer on all merchantable trees. COR may identify trees that require a 10-foot no-treat buffer to protect boles and roots. Operate around areas where merchantable trees less than 20 feet apart from base to base. Avoid damage to standing merchantable trees.

For retaining sub-merchantable trees, the COR will state if a particular species should be preferred for leaving or cutting.

Leave all snags possible standing in harvest areas unless required to be felled for safety reasons.

Monumented trees and corners will be left standing. Contractor shall use every precaution to prevent damage to trees that are to be protected. Excessive damage will be considered unacceptable and will result in no payment of site/unit. Monument tree damage will be assessed by a Surveyor/Engineer.

Quality Standard: All trees 5 inches DBH or larger are left standing, unless otherwise described by the COR. All trees with flagging or painted trees are left standing.

Tractors If a crawler tractor is used for site prep, it should be equipped with track pads having grousers in good condition. For mechanical site prep operations, the contractor will have to provide a tractor with a minimum of 200 flywheel horsepower.

Quality Standard: Tractors have enough power to safely and effectively move earth and debris.

Soils, Wetlands, and Rutting Avoid creating ruts greater than 6" deep. Rutting will be considered non-compliant when more than 5% of the surface area of a unit is impacted. Rutting on slopes greater than 18% will require water barring as approved by the COR.

Slash will not be pushed onto non-forested wetlands.

Streams and standing water will be avoided at a minimum of 25 feet.

Quality Standard: Less than 5% of a site is impacted by rutting. No slash is on wet, lowland, or transitional soils. Streams and standing water are buffered by 25 feet.

Sanitation There will be no trash (oil, rags, wrappers, etc.) left on National Forest System land by the contractor or his/her employees.

Quality Standard: No trash is in site prep units.

Equipment cleaning Contractor shall not move any Off-Road Equipment that last operated in an area that is infested with one or more invasive species of concern without having first taken reasonable measures to make each such piece of equipment free of soil, seeds, vegetative matter, or other debris that could contain or hold seeds. Contractor shall identify the location of the equipment's most recent operations. If the prior location of the Off-Road Equipment cannot be identified or the presence of invasive species of concern is unknown, the Forest Service will assume that it is infested with seeds of invasive species of concern. Operations will cease until proper cleaning measures and COR inspection has taken place.

Contractor shall not unload/move any Off-Road Equipment onto contract areas prior to having it inspected by the COR or other designated Inspector. Inspections will occur on the trailer before equipment is unloaded onto Forest Service land. COR or Inspector shall have 2 days, excluding weekends and federal holidays, to inspect equipment after it has been made available for inspection. During the winter shearing and winter rock rake operations, equipment is still expected to be reasonably clean prior to operations. Equipment hauled off site to do other work will need to be re-cleaned and re-inspected, prior to continuing work on Forest Service property.

In addition, prior to moving Off-Road Equipment from a contract site that has been shown to be infested with seeds of invasive species of concern to any other unit that is indicated as being free of invasive species of concern, Contractor shall again take reasonable measures to make each such piece of equipment free of soil, seeds, vegetative matter, or other debris that could contain or hold seeds.

Contractor must advise the COR of measures taken to clean Off-Road Equipment and arrange for COR prior to such equipment being placed in service or moved from contract sites infested with invasive species of concern to units that are free of such invasive species.

A list of invasive species of concern is available upon request. A map showing the extent of known infestations on the Superior National Forest is also available upon request.

Quality Standard: All equipment used on site is free of weed seeds before arriving.

ROAD USE AND MAINTANENCE

All roads leading into each project area are to be kept open and free of any debris that may occur as a result of the work. All existing roads used by the Contractor shall be left in the same condition, or better, as when the operation started. Prior to the start of work, the Contractor and COR will review and document existing road conditions to provide a basis for maintenance needs.

Damage done to roads and trails in the project areas shall be repaired immediately by the contractor at the Contractor’s expense.

Quality Standard: Roads free of debris and in same or better condition as when the operation started.

Temporary Access Closure If the Contractor creates access to a unit from a Forest Service, County, or other road, the Contractor will restore the closure to effectively block access trails to motorized traffic upon completion of work. This may include moving rocks (embedded 1/3 of their depth), stumps, small balsam, and spruce where available nearby (transplanted into roadbed), and/or slash randomly placed 50 feet from the trail entrance for a minimum distance of 200 feet or to the end of the seen area to ensure that passage does not seem feasible and is not attempted. See “Attachment A - Road Closure Illustration: Blocking All Motorized Traffic” and “Attachment B - Road Closure Illustration: Blocking All Motorized Traffic Except ATVs”.

If the Contractor uses a road originally built by a timber purchaser, the Contractor will restore the road to its condition before site prep operations (i.e., decommissioned temp road, barricaded), unless the COR specifies otherwise.

Quality Standard: Temporary access trails are effectively closed to motorized traffic.

RESOURCE PROTECTION

Streams, Lakes, and Reservoirs The Contractor shall take every precaution to prevent pollution from fuels, oils, chemicals, silt or other harmful materials of any stream, lake or reservoir located in or near the contract areas.

All streams shall be kept free of Contractor-generated debris.

Areas of significant wildlife value If areas of significant wildlife value are encountered during the performance of work contact the COR for further evaluation. Examples of potential areas of significant wildlife value are: a large stick nest, animal den, areas of advanced pockets of regeneration such as conifer.

Fire prevention and control Depending on the local fire danger conditions, the contractor will require that smoking and lunch or warming fires be confined to established camps or to designated safe places. On high or extreme fire danger days, the contractor or his/her employees will be required to patrol the work area for a one-hour period after the equipment has been shut down for the day. A working fire extinguisher is required on the equipment being operated.

Damage to government buildings, equipment, and reserve trees In accordance with FAR Clause 52.237-2 Protection of Government Buildings, Equipment, and Vegetation (APR 1984), the Contractor shall use reasonable care to avoid damaging existing buildings, equipment, and vegetation on Government property. If the Contractor's failure to use reasonable care causes damage to any of this property, the Contractor shall replace or repair the damage at no expense to the Government as the COR directs. If the Contractor fails or refuses to make such repair or replacement, the Contractor shall be liable for the cost, which may be deducted from the contract price.

For the purpose of this clause, damage to merchantable trees or protected trees will result in a $300 payment reduction per damaged tree. Cost for damage to monumental tree damage will be assessed at actual cost to the Government.

SPECIAL CONDITIONS

Any special conditions will be noted on contract maps.
