TABLE 1

( ) The value in the parentheses is the allowable deviation () from the target values.

PART 3 – EXECUTION

3.1 LOCATION, ALIGNMENT AND GRADE

A. The limits of excavation, and cut and fill reference shall be staked out by the contractor. Staking shall be approved by the contracting officer prior to the start of material extraction.

B. A copy of the AutoCAD files shall be made available to the Contractor upon request, for the purposes of developing stakeout points.

3.2 MATERIAL EXTRACTION

A. Clear and Grub all vegetation within the limits of excavation and utilize any organic debris at the end of the project for site reclamation. The removal of soil contaminated with invasive weed seed is required; remove the top 12 inches of overburden within on-site flagged perimeter, area also shown on the drawings. Dispose of contaminated soil at Designated Quarry Disposal Site, shown on the project drawings.

B. Prior to the start of work, the Contractor shall have a surveyor provide stake out points, to delineate the limits of excavation. The stakeout points will be provided by the Forest Service.

C. The Contractor shall determine the most effective means for extracting material from the hillside. If it is determined that the most effective means for material extraction is blasting instead of mechanical ripping, refer to Part 3.4 for details.

D. Excavate into the hillside and harvest all material to the subgrade elevations and grades provided in the drawings. Monitor the excavation to verify that the material being extracted is basaltic in nature; if material consistency changes to decomposed granite or another material, the Contractor shall cease excavation and inform Contracting Officer immediately. Only extracted and processed basalt will be accepted by the Forest Service.

E. The Contractor shall strip any topsoil or overburden deemed not suitable for use in the crusher, where indicated on the ground by Forest Service personnel; stockpile this material for re-use in site reclamation at the end of the project. Other deleterious material extracted from the hillside shall also be stockpiled away from the crushed aggregate stockpiles.

F. Maintain the excavations to guard against and prevent injury to employees and the public, and to reduce the amount of material lost to surface runoff erosion. Cut and fill areas will be stabilized at the end of each day by constructing gentle slopes of 1:1 or flatter.

3.3 PROCESSING & STORAGE

A. Prior to crushing, take the following actions:

1. All organic matter, lumps or balls of clay, and other deleterious matter shall be removed. All unsuitable inorganic material shall be stockpiled onsite and not utilized for crushing.

2. Consolidate existing stockpiles to locations shown on the drawings.

3. At stockpile locations, the existing ground shall be leveled (but still matching the existing grade) of rocky and organic debris.

B. Contractor shall provide for crushing all equipment suitable for crushing material to the required gradation. Rock crushing equipment shall be erected within the borrow pit, and in a manner which will not disrupt overall operations.

C. The contractor shall take a gradation sample, in accordance to ASTM D-422, and have a State Certified Laboratory verify that the material being processed is meeting contract requirements. The Contractor shall sample at the following intervals:

1. At start of production, obtain one sample after the first 100 cubic yards has been processed through the crusher, to verify the crusher is properly functioning. If the gradation of the initial sample is out of specification, the Contractor shall process another 100 cubic yards of aggregate and take another sample to verify compliance. If necessary, the Contractor shall continue taking a sample every 100 cubic yards until the crusher is producing aggregates at the required gradation.

2. After initial sampling has verified crusher is producing aggregates to specification, the Contractor shall take one sample every 600 cubic yards of material processed (verification sample). If verification sample fails, adjust crusher to correct the gradation; process 100 cubic yards of material and take sample to verify gradation; repeat this process until material is being processed to the correct gradation.

3. If Contractor processes less than 600 cubic yards of crushed aggregate per day, the Contractor shall take a minimum of one gradation sample per day.

D. Consolidate processed material into stockpiles, over prepared surfaces (reference Part 3.3) at designated locations inside the quarry. Maintain slopes of the stockpiles to be no steeper than 1.5:1 and 20 feet maximum height. Older stockpiles that were consolidated prior to the start of excavation shall remain segregated from the newer stockpiles, for the purpose of accurately determining the amounts of new material processed.

3.4 BLASTING

A. Before drilling, remove overburden soil and loose rock along the top of the excavation for at least 30 feet beyond the hole drilling limits or to the end of the cut.

B. Cap all holes to prevent unwanted backfill from falling into the holes, and place a stake next to each hole with the hole number and total depth drilled.

C. Use the types of explosives and accessories in accordance to the blasting plan.

D. Free blast holes of obstructions for their entire depth. Place charges without caving in the blast hole wall. Provide stemming for the upper portion of each blast hole with dry sand passing the 3/8” sieve.

E. Follow each blast, stop all work on site and check for misfires before allowing workers to return to the site.

F. Repair or stabilize any fracturing of the final rock face in an approved manner and at no additional costs to the Forest Service.

G. Halt blasting if slopes become unstable, exceed tolerance and creates overhangs, backslope damage occurs, safety to workers and public is jeopardized, property or natural features are endangered, fly rock is generated, or excessive ground or airblast vibrations occur. The Forest Service reserves the right to implement test blasting if any of these conditions occur, and at no additional costs to the Forest Service.

H. Submit drill logs, indicating the following details:

1. Blast map showing designated hole numbers.

2. Individual hole logs completed and signed by the driller that show total depth drilled, depths and descriptions of significant conditions encountered during drilling operations, and the date of drilling.

3.5 STORMWATER MANAGEMENT / DEWATERING

A. Site Development must ensure positive drainage to prevent water from pooling or flooding the pit. The following measures shall be implemented to enhance re-establishment of equilibrium and minimize erosion and ponding water onsite:

1. Minimize the amount of area disturbed during material extraction, processing, and stockpiling.

2. Areas of unexpected settlement shall be filled to re-establish natural contours and eliminate ponding water.

3. Swales and other erosion control measures shall be implemented to re-direct surface runoff inside the excavation and to reduce the amount of erosion throughout the site.

4. Cut and fill slopes shall be laid back at no steeper than 1:1 at the end of each work day.

B. As part of Pit Development plan, a section shall be dedicated to Storm Water Management/ Dewater Procedures. The following items shall be included in the management plan:

1. Proposed locations of drainage and erosion control structures.

2. Design details for proposed drainage structures.

3. Material list of drainage and erosion control materials.

4. Equipment to be used for dewatering pit.

3.6 SITE RECLAMATION

A. After the contracted amount of material has been crushed and accepted by the Forest Service, proceed with reclaiming the site by conducting the following procedures:

1. Dismantle and transport all crushing plant equipment off Forest.

2. Final grade the side slopes and bottom of the excavation to the lines and grades shown on the drawings; re-use any overburden or topsoil stockpiled on the top layer for the finished ground surface. Any rock fractures remaining in the final slopes shall be excavated and the back slopes re-set, if determined to be unsafe by the Contracting Officer.

3. To maintain positive drainage, it may be necessary for additional ground outside of the limits of excavation (as shown on the drawings) to be graded. The Contracting Officer shall make the determination of where additional grading is required to maintain positive drainage.

4. Any areas of disturbance from pit activities shall be treated to the satisfaction of the Forest Service.

5. Install additional drainage structures around stockpiles, as shown on the drawings and determined in the field by the Forest Service. Other drainage structures constructed during the contract may be left in place, as determined by the Forest Service.

B. WASTE DISPOSAL

1. Any material not consisting off basalt (and thus not used for crushed aggregates) that was extracted shall remain onsite and be placed in stockpiles at designated locations in the pit.

2. All weed-contaminated soils shall be stockpiled at the Designated Quarry Site, shown on the project drawings

3. Organic materials, such as stumps, logs, and slash and all other unsuitable material shall be hauled to an approved landfill, or scattered onsite under the coordination with the Contracting Officer.

4. All hazardous materials (contaminated soils caused by fuel or other fluid spillage), garbage, and other refuse generated shall be removed from the project site and legally disposed of Government property in an approved landfill.
