116.01 - (a) All work (which term includes but is not limited to materials, workmanship, and manufacture and fabrication of components) shall be subject to inspection and tests by the State at all reasonable times and at all places prior to acceptance. Any such inspections and tests are for the sole benefit of the State and shall not relieve the contractor of the responsibility of providing quality control measures to assure that the work strictly complies with the contract requirements. No inspection or tests by the State shall be construed as constituting or implying acceptance. Inspection or test shall not relieve the contractor of responsibility for damage to or loss of the material prior to acceptance, nor in any way affect the continuing rights of the State after acceptance of the completed work under the terms of paragraph (f) of this clause, except as hereinabove provided.

(b) The contractor shall, without charge, replace any material or correct any workmanship found by the State not to conform to the contract requirements. The contractor shall promptly segregate and remove rejected material from the premises.

(c) If the contractor does not promptly replace rejected material or correct rejected workmanship, the State (1) may, by contract or otherwise, replace such material or correct such workmanship and charge the cost thereof to the contractor, or (2) may terminate the contractor's right to proceed in accordance with the clause of this contract entitled "Cancellation".

(d) The contractor shall furnish promptly, without additional charge, all facilities, labor, and materials reasonably needed for performing such inspection and tests as may be required by the engineer. All inspection and test by the

State shall be performed in such manner as to not unnecessarily delay the work. Special, full size, and performance tests shall be performed as described in this contract.

(e) Should it be considered necessary or advisable by the State at any time before acceptance of the entire work to make an examination of work already completed, by removing or tearing out some, the contractor shall, on request, promptly furnish all necessary facilities, labor, and materials. If such work is found to be defective or nonconforming in any material respect, due to the fault of the contractor or his subcontractors, he shall defray all the expenses of such examination and of satisfactory reconstruction.

(f) Unless otherwise provided in this contract, acceptance by the State shall be made as promptly as practicable after completion and inspection of all work required by this contract, or that portion of the work that the engineer determines can be accepted separately. Acceptance shall be final and conclusive except as regards latent defects, fraud, or such gross mistakes as may amount to fraud, or as regards the State's rights under any warranty or guarantee.

(g) Upon due notice from the contractor of presumptive completion of the entire project work, the engineer will make an inspection. If all construction provided for and contemplated by the contract is found completed to his satisfaction, a final inspection will be scheduled within five (5) days. The final inspection shall be conducted by the Program

Manager of the Land Reclamation Section or his designee, the Division Engineer, and the Project Officer. The contractor shall be present along with his superintendent and all subcontractors, if any, that have worked on the project.

The contractor shall not remove any equipment from the site until after he receives written notice of final acceptance of the work. Written notice of the final inspection and acceptance will be issued to the Contractor stating final acceptance and the date of release.

If, however, the inspection discloses any work in whole or in part, as being unsatisfactory, the engineer will give the contractor the necessary instructions for the correction of the deficiencies and the contractor shall immediately comply with and execute such instructions. Upon completion of the corrective work, another inspection shall be made which shall constitute the final inspection provided all work has been satisfactorily completed.

Section 117.0 - Accidents

The contractor shall provide, at the site and at his own expense, such equipment, and medical facilities as are necessary to supply first-aid service to anyone who may be injured in connection with the work.

The contractor must promptly report in writing to the project officer all accidents whatsoever arising out of, or in connection with, the performance of the work, whether on, or adjacent to the site which caused death, personal injury, or property damages, giving full details and statements of witnesses. In addition, if death, serious injuries, or serious damages are caused, the accident shall be reported immediately by telephone or messenger to both the project officer and the contracting officer.

If any claim is made against the contractor or any subcontractor on account of any accident, the contractor shall promptly report the facts in writing to the project officer, giving full details of the claim.

Section 118.0 - Completion Time

The completion time is approximately 300 days, which includes no days for bad weather, holidays, or weekends.

The Contractor shall take this time frame for completion into consideration when bidding on this project. An extension shall not be granted unless there are unusual circumstances, such as an act of God. Poor planning, inefficiency, equipment breakdown, or any other factor of which the Contractor has control over shall not be justification for time extensions.

Performance milestones will be enforced on the project. If 25% of the acreage is not completed by Day 75 of the contract, the Contractor will be given a warning. If 50% of the acreage is not completed by Day 150 or 75% of the acreage is not completed by Day 225 of the contract, the contract will be terminated in accordance with Section 7 of the contract terms and conditions.

Section 119.0 - Safety

The contractor shall conduct his operations in such a manner that all applicable laws and regulations are adhered to during performance of this contract.

119.01 - The contractor shall provide, erect, and maintain all necessary barricades, suitable and sufficient lights, danger signals, signs, and other traffic control devices, and shall take all necessary precautions for the protection of the work and safety of the public.

119.02 - No direct payment will be made for work required in this section, but the cost thereof will be considered to be included in bid price for mobilization.

Section 120.0 - Dust Control

The contractor shall take all available precautions to control dust. Dust shall be controlled by sprinkling, by applying calcium chloride, or by other methods as approved. If sprinkling is the selected method for controlling dust, the contractor shall water as often as necessary to control dust that is produced as a result of the movement of construction equipment and vehicles. The use of other methods shall be effective in preventing dust formation. Oil shall not be used.

Section 121.0 - Superintendence by Contractor

The contractor, at all times during performance and until all the work is completed and accepted, shall give their personal superintendence to the work, or have on the project a competent superintendent, satisfactory to the division

Program Manager and with authority to act for the contractor.

Section 122.0 – Prevailing Wages & Davis-Bacon Act

This project is funded through a federal grant from the U.S. Department of Interior’s Office of Surface Mining. The

Davis-Bacon Act requires that all contractors and subcontractors performing construction, alteration, and repair (including painting and decorating) work under federal or District of Columbia contracts in excess of $2,000 pay their laborers and mechanics not less than the prevailing wage and fringe benefits for the geographic location. Construction or renovation projects funded by federal funds, in whole or in part, are subject in their entirety to the Davis-Bacon Act as amended in 40

U.S.C. parts 276(a) through 276(a5). Award recipients are required by law to furnish assurances to the Secretary of Labor that all laborers and mechanics employed by contractors or subcontractors on DOI-supported construction projects shall be paid wages at rates that are not less than those prevailing on similar construction in the locality, as determined by the

Secretary of Labor.

Among other requirements, contractors and subcontractors must:

• Pay at least the Davis-Bacon prevailing wages listed in the applicable wage determinations included in the contract to laborers and mechanics who work in the site of work. The Davis-Bacon prevailing wage is the combination of the basic hourly rate and any fringe benefits listed in a Davis-Bacon wage determination.

Contractors can meet this obligation by paying each laborer and mechanic the applicable prevailing wage for the classification of work they perform entirely as cash wages or by a combination of cash wages and employer-provided bona fide fringe benefits;

• Pay laborers and mechanics the applicable prevailing wages for all hours worked on the site of the work on a weekly basis (except for contributions to bona fide fringe benefit plans, which must be made at least quarterly);

• Maintain an accurate record of hours worked and wages paid, including fringe benefit contributions;

• Submit certified payrolls to the contracting agency/funding recipient each week, within seven days of the payroll date for that workweek; and

• Ensure that the required contract clauses and applicable wage determinations are incorporated into any lower-tier subcontracts.

Additional information concerning the Davis-Bacon Act and current wage rate determinations can be obtained at the following sites: www.gpo.gov/davisbacon/referencemat.html and www.wdol.gov/.

Section 123.0 – Tennessee One-Call Center

In the state of Tennessee, state law requires anyone about to engage in either digging, excavation, moving of earth, demolition, or any type of activity that disturbs the earth and therefore possibly involving a danger to damaging underground utility lines, to notify the Tennessee One-Call Center of their intent to dig.

Tennessee One-Call will then notify the member utilities of your proposed work. The utility company locator will then have 72 hours, excluding holidays and weekends, to locate those underground facilities.

While not required by law, in addition to calling Tennessee One-Call, you may also want to contact any non-member utilities that you know are in the area of your proposed work.

The locate ticket you receive is only valid for 15 calendar days from the start date indicated on the ticket, after which time, it expires. If you wish to continue working, you must call in at least three working days before the expiration date to renew your locate ticket, at which time you would be given a new ticket number.

The contractor must call the Tennessee One-Call Center at 811 or 1-800-351-1111 at least three days prior to starting work. Tennessee 811 accepts locate requests 24 hours a day, seven days a week.

Section 124.0 - Build America Domestic Procurement Preference

This project is funded through a federal grant with U.S. Department of Interior’s Office of Surface Mining. As required by Section 70914 of the Infrastructure Investment & Jobs Act, P.L. 117-58, none of the funds under a federal award that are part of Federal financial assistance program for infrastructure may be obligated for a project unless all of the iron, steel, manufactured products, and construction materials used in the project are produced in the United States.

The requirements of this section must be included in all subawards, including all contracts and purchase orders for work or products under this project.

None of the federal funds provided to the Land Reclamation Section may be used for a reclamation project unless:

1. all iron and steel used in the project are produced in the United States – this means all manufacturing processes, from the initial melting stage through the application of coatings, occurred in the United

States;

2. all manufactured products used in the project are produced in the United States – this means the manufactured product was manufactured in the United States; and the cost of the components of the manufactured product that are mined, produced, or manufactured in the United States is greater than 55 percent of the total cost of all components of the manufactured product; and

3. all construction materials are manufactured in the United States – this means that all manufacturing processes for the construction material occurred in the United States.

The Buy America preference only applies to articles, materials, and supplies that are consumed in, incorporated into, or affixed to an infrastructure project. It does not apply to tools, equipment, and supplies brought to the construction site and removed at or before completion of the project.

Section 200.0 - Mobilization

Description

200.01 – The project consists of three work sites. Access to the sites will require mobilization of equipment to three different locations.

Mobilization shall include the purchase of contract bonds; transportation of personnel, equipment, and operating supplies to the site; establishment of offices, buildings, and other necessary facilities at the site; and other preparatory work at the site. The specification covers mobilization for work required by the contract at the time of award.

Demobilization is also included under this Section. All equipment will be removed from the site before final payment is made under this Section.

Area 1 has cattle roaming on the abandoned strip mine. A fence will be installed below the work limits to keep the livestock from the construction site. Payment for supplying the materials, labor, and equipment necessary for the installation of 3,500 feet of barbed wire fencing and a 20-foot cattle gate will be included in the lump sum bid under this

Section. Additional details for fence installation are in Section 204.0, Area Grading.

A land surveyor licensed in the State of Tennessee shall be required for this project. There is one property corner that must be relocated after construction has been completed. The surveyor will be responsible for any research (locating deeds, locating surveys, etc.) necessary to accurately locate the property corner. The cost for furnishing the licensed surveyor and all work required to place the property pins shall be included in the lump sum price bid under this Section.

The general location of the property pin shown on the drawings is only an approximation and should be taken as such.

Measurement and Payment

200.02 - Measurement will be one (1) job for all work completed under Mobilization.

Payment will be made lump sum and shall be full compensation for furnishing and applying all materials, labor, equipment, and other incidentals necessary to complete the work.

Section 201.0 - Clearing and Grubbing

Special Project Specifications

201.00 – Clearing and grubbing limits will be flagged by the Project Officer. The Contractor shall confine all work within the flagged area. Care shall be taken to not damage any trees outside the flagged limits. Most of the clearing debris will be chipped and utilized for sediment control.

All clearing debris twenty-inch (20”) diameter or smaller shall be treated according to Method 5 (Chipping) of

Section 201.05. Chipped debris will be utilized as mulch filter berms for sediment control and onsite soil stabilization measures where appropriate. The Project Officer will determine where the chipped debris is to be placed. Excess chipped debris will be placed in the bottom of the pits. Remaining stumps will be buried in the bottom of the pits. Acceptable mulch filter berms will be paid to the nearest one liner foot under Section 211.0, Silt Retention Barrier.

All other clearing debris shall be treated according to the following methods: Method 1 (Windrowing Construction

Slash), Method 4 (Burying), and Method 6 (Piling and Burning) of Section 201.05. Disposal of clearing debris by these methods will only be done with the approval of the Project Officer.

Windrowed brush will be stacked at locations determined by the Project Officer. The windrows will consist of densely packed treetops and saplings to act as a filter to aid in sediment control.

If burning is required, the Contractor shall follow all applicable laws and ordinances. The Contractor shall ensure burning operations proceed under the constant care of competent watchmen at all times and in a manner that will not harm the surrounding vegetation or adjacent property.

If the contractor wishes to harvest merchantable timber from the site, the contractor will be responsible for working out an agreement with the landowner. If no agreement can be reached, the timber will be disposed of by the aforementioned methods in this Section.

After grade work has been completed, the State will survey the work areas to determine the acreage of the work completed. Horizontal measurement shall be used in the data collection. Payment will be made to the nearest 0.1 acre surveyed.

201.01 - This work shall consist of clearing, grubbing, trimming, removing, and disposing of timber, construction slash, and debris. This work shall also include preservation of vegetation and objects designated to remain from injury or defacement.

Construction Requirements

201.02 – Clearing and Grubbing: All debris, trees, stumps, roots, and other protruding obstructions within the clearing limits, not designated to remain, shall be cleared, grubbed, removed, and disposed of, except for the following:

(a) Undisturbed stumps outside the embankment areas, provided they do not extend more than 12 inches above the original ground nor closer than two (2) feet to the finished sub grade or one (1) foot to any slope surface and do not interfere with the placement or compaction of embankments.

(b) Stable trees up to six (6) inches in diameter within the clearing limits but beyond the embankment and uncut vegetation less than three (3) feet in height and less than three (3) inches in diameter.

(c) Grubbing of pits, channel changes, rock sections, and channels below the depth of the proposed excavation.

All roots over three (3) inches in diameter within the embankment area shall be grubbed to a minimum depth of six (6) inches below sub grade. Roots protruding from the excavated slope shall be cut flush with the excavated slope surface.

Trees shall be felled into the area being cleared when ground conditions, tree lean, and shape of clearing permit.

Controlled felling shall be used that will ensure the direction of fall when necessary to prevent damage to property, structures, trees designated to remain, or traffic.

Snags and trees outside the clearing limits that are designated for individual removal shall be cut off not more than 12 inches above the ground and treated in accordance with Subsections 201.03 and 201.05.

Limits of work are flagged on the ground by means of paint or colored ribbon. All work shall be confined within the flagged boundary. Any clearing done outside the flagged boundary will not be paid for.

201.03 – Disposal of Merchantable Timber (Timber Meeting Utilization Standards): Timber meeting utilization standards shall be disposed of in accordance with the Special Project Specifications.

201.04 - Pioneer Roads: The construction of pioneer roads shall be approved by the engineer.

201.05 - Slash Treatment: Treatment of construction slash shall be accomplished by one or more of the following methods:

(1) Windrowing Construction Slash: Areas used for windrow construction slash shall be cleared to accommodate the windrow. Construction slash shall be placed outside the embankment in neat, compacted windrows laid approximately parallel with the toe-line of embankment slopes. The top of windrows shall not extend higher than ten (10) feet. All material in the windrow shall be matted down with construction equipment to form a compact and uniform pile. Windrows shall have 16-foot minimum length breaks at least every 200 feet. Windrows shall not be placed against trees. A pioneer road may be constructed to provide an area for placement of windrows provided the excavated material is kept within the clearing limits and does not adversely affect the embankment construction.

(2) Windrowing of Large Material: Construction slash ten (10) inches or more in diameter at the small end and six (6) feet or more in length shall be windrowed as in subsection (1) above. Small material shall be treated by one or more of the other included options for slash treatment.

(3) Windrowing and Covering: Construction slash shall be placed and compacted as in subsection (1) above and shall be covered with at least six (6) inches of rock and soil to form a smooth and uniform windrow.

(4) Burying: Construction slash shall be buried at the locations shown on the drawings and designated on the ground. Construction slash shall be matted down in layers and covered with at least two (2) feet of rock and soil. The final surface shall be smooth and sloped to drain.

(5) Chipping: Construction slash up to at least twenty (20) inches in diameter shall be processed through a chipping machine. Chips shall be deposited on embankment slopes to a loose depth not exceeding six

(6) inches. Minor amounts of chips may be permitted within the embankment if they are thoroughly mixed with soil and do not form a layer.

(6) Piling and Burning: Construction slash shall be burned in areas shown on the drawings and designated on the ground. Piles shall be constructed so that burning does not damage standing trees. If burning is incomplete, the slash remaining shall be piled and burned until the pieces are reduced to less than three (3) inches in diameter and three (3) feet in length. These pieces shall then be scattered.

The contractor shall conduct burning operations in compliance with all local, state, and federal laws, ordinances, and regulations. It is the contractor's responsibility to obtain all licenses, permits, payment of fees, etc., to comply.

(7) Decking Unmerchantable Material: Logs not meeting utilization standards that are six (6) inches or more in diameter shall be bucked into lengths not to exceed 32 feet and piled at the locations shown on the drawings.

Pieces of wood that are less than three (3) inches in diameter and three (3) feet in length may be scattered within the clearing limits.

No material shall be deposited in lakes, meadows, streams, or streambeds. Construction slash that interferes with drainage structures shall be removed immediately.

Trees adjacent to the clearing limits scorched or damaged beyond recovery shall be felled and disposed of in accordance with Subsection 201.02 or treated as construction slash.

201.06 - The method of measurement will be to the nearest 0.1 acre for all work completed and accepted. Horizontal measurement shall be used in the data collection.

Payment will be paid at the contract unit price bid per acre and shall be full compensation for furnishing and applying all materials, labor, equipment, and other incidentals necessary to complete the work.

Section 204.0 - Area Grading

204.00 - The work in this section consists of the moving of landslide material and the grading of spoil to eliminate pits and highwalls.

Site 1 is a contour mine that consists of a landslide, highwalls, spoil piles, and four water-filled pits. The site totals

33.2 acres. The landowner currently has cattle fenced-in on the site. Before construction can begin, a five-strand barbed wire fence with 6-foot T-posts and a 20-foot gate will be constructed below the spoil to keep the cattle off the site. The fence will be left in place after construction has been completed. The Contractor will coordinate the location of the fence with the Project Officer and the landowner. Three thousand five hundred (3,500) feet of fencing shall be required.

Payment for the materials and the installation of the fence and gate will be included in the price bid, lump sum under

Section 201.0, Mobilization.

The highwalls at Site 1 range from 30 to 50 feet in height. The backfilled highwalls will have final grades ranging from a 3:1 slope to flatter than 10:1 slope in places. The site has four water-filled pits. Two of the pits (#3 and #4) are not to be disturbed. The spoil adjacent to these water pits will be graded to serviceable slopes. The two water pits to be backfilled (#1 and #2) had a pH of over 6.0 when field checked by department personnel. No treatment should be required, but the water quality must be checked before backfilling operations can begin to ensure that water characteristics have not changed. If water quality has changed, the water may require treatment before discharging.

Requirements for treatment and discharging water are in Section 214.0, Pond Treatment and Dewatering, of the specifications. The approximate cut/fill yardage for the site, including the landslide, is 297,000/295,000 cubic yards. See sheet 3 of the drawings for proposed final grade of backfilled slopes at locations along the site.

There is a four-acre landslide above one section of highwall at Area 1. The landslide material must be excavated down to solid ground before backfilling the pit and highwall. The excavated material will be placed at the bottom of the pits. The material will be pushed or hauled to disposal areas up to 1,000 feet from the landside area. The quantity of material to be excavated is approximately 70,000 yd³. The material quantity is an estimate, as in-place landslide material is difficult to determine.

Moving landslide material will be considered a separate pay item than Area Grading for backfilling highwalls and grading spoils. After the landslide area has been cleared and grubbed, the Project Officer will survey the limits of the landslide area. The surveyed area will be considered the final quantity for the pay item under this Section 204.0(b), Landslide Grading. All other grade work will be paid under this Section 204(a), Area Grading.

There is a small stream that runs through the mining at the west end of Site 1 – Area 4. Four hundred (400) feet of stream will be reconstructed after backfilling the highwall. The stream will have two drop structures and several stream enhancement features. On site rocks and trees will be gathered during grade work for the stream features. The Project

Officer must be onsite to locate and approve the construction of the stream structures. There is a water line that runs along the road adjacent to the stream. Care will be taken not to damage the water line buried along the road. See Section

304.0, Stream Channel and Riparian Habitat Restoration and sheet 9 of the drawings for details on stream restoration.

Site 2 is located on White Oak Road. It consists of a 7.0-acre area mine. The area has no highwalls. It consists of numerous rows of spoil piles. The spoil will be graded to create crowned pasture. The edges of the crowned surface will have a slope of 3:1 or flatter. One row of spoil will not be disturbed on the southwest edge along White Oak Road to discourage trespassing. The approximate cut/fill yardage for the site is 43,000/42,000 cubic yards. Cross sectional drawings for the site are shown on sheet 5 of the drawings.

Site 3 consists of two areas located on Roses Creek Road. Area 6 is a 16.3-acre contour mine. The strip mine has highwalls up to 50 feet tall. The highwalls will be backfilled to the approximate original contours. The final grade will slope from the top of the highwall to the toe of the spoil. The highwall will be backfilled to a 3:1 slope in most places. The approximate cut/fill yardage for the area is 196,000/190,000 cubic yards total. Cross sectional drawings for the site are shown on sheet 8 of the drawings.

Area 7 is 8.8 acres. The area is a small ridge that has been mined completely around. The highwalls are 20 feet tall or less. The backfilled highwalls will have grades ranging from a 3:1 slope to a 7:1 slope. Cross sectional drawings for backfilled slopes are shown on sheet 8 of the drawings.

Before backfilling operations can begin, all water in pits shall be tested to ensure they meet water quality standards. All water-filled pits shall be pumped or drained down prior to backfilling to not create mud or sludge. See

Section 214.0, Pond Treatment and Dewatering for details on individual pits.

Method 1 of Section 204.03, Side Casting, will be used for placing fill in pits and backfilling highwalls. The backfilling and grading of the pits and depressions where water is still pooled after pumping and draining shall be in a slow, consistent operation that allows the soil to absorb the remaining water. Backfilling must cease when the ground within the water-filled pits becomes unstable to the point the backfill will not support the weight of a dozer.

The material at the base of the highwall must be walked-in every ten (10) vertical feet in order to reduce settling of backfill material. Compaction by rolling with the earthmoving equipment used for grading operations will be acceptable.

All slopes will be tracked in perpendicular to the slope when grading is complete or when active grading operations of the slope will cease for more than 72 hours or before an anticipated rain event.

Grade work will provide positive drainage on all graded areas and will eliminate all depressions that can hold water. After all rough grading is complete, surface drainage shall be provided by construction of rip-rap channels, grass-lined waterways, and terraces. The Project Officer will determine where drainage channels are required, both those specified and any additional channels. Where the grade on grassed waterways exceeds three (3) percent, rip-rap channels lined with filter fabric and rip-rap will be constructed. Typical sections for terraces, grassed waterways, and rock-lined channels are shown on sheet 9 of the drawings.

Terraces will be needed to break up sheet flow runoff over the backfilled slopes. The Project Officer will determine and mark the locations for the terraces that are constructed. The grade of the terraces shall not exceed two (2) percent.

The grade of the terraces shall be checked with a level, transit, or other comparable method.

Terrace construction, grass-lined waterway construction, rock-lined channel construction, and anoxic limestone drain construction are included in the unit price bid under Section 204.0(a), Area Grading.

After grade work has been completed, the State will survey the sites to determine the area of the work completed.

Horizontal measurement shall be used in the data collection.

204.01 - The work in this section consists of the excavation, filling, and grading of all materials of whatever nature. It includes all hauling, formation of fills and embankments, ditch excavation, berm construction, disposal of unsuitable or surplus material, and finishing and final dressing.

Materials

204.02 – a. The materials required for this work shall be the in-situ materials on site unless stated otherwise in this contract special provisions.

b. Fencing- The barbed wire shall be 12.5-gauge wire with 4-point barbs at maximum 5-inch intervals. The top wire will be at least 42-inches from the ground, and the bottom wire will be at least 14-inches from the ground. Posts will be 6’ metal T-posts spaced 8-feet apart. Wood posts will be installed as needed and H-braces will be required every 200’ feet and at all corners.

Construction

204.03 - Construction of Fills: Final grade shall approximate the lines and grade configuration shown on the plans.

Regardless of the method of fill placement, the fill shall be constructed so that positive surface drainage shall be provided at all times. Ponding of water will not be allowed on the surface of the fill. Fill material may be placed in one of several different methods. These options are listed, and any required option or options shall be shown on the drawings.

Method of placing fill:

(1) Side Casting: This method allows the dumping or pushing of material over the side of previously placed material. The material pushed or dumped must not exceed four (4) feet in thickness on the face of previously placed material. This method may be used in areas where finished grade is not critical to establishing final drainage patterns and in areas where settlement is not considered a problem. Small amounts of herbaceous and vegetative material (trees and brush) will be permitted in the base of the fill, provided it is not bunched up to form a loose pile of brush that will rot and leave a void that results in subsidence. When trees and brush are placed in the fill, the trees and brush shall be placed on the bottom of the pit and compacted to form a dense mass not to exceed four (4) feet in thickness. This method of brush disposal will only be allowed where future subsidence will not cause pits to be formed, and disposal areas will be shown on the drawings. Scattered individual trees may be allowed in the fill provided they are on the bottom of the pit area and fill material completely surrounds the trees.

Compaction is not required. This method is particularly applicable for pushing off spoil ridges into open pits to form a uniform finished grade that approximates original contour or contour shown on the drawings.

Pits that are holding water and designated to be backfilled shall be dewatered before backfilling.

See Section 214.0, Pond Treatment and Dewatering.

In some instances, pits with shallow water may be backfilled with the pushing of earth material into the pit from the end and absorbing the water with the soil material. In the event absorption is allowed, the contractor shall push backfill material slowly to allow the soil particles to absorb the water and remain stable to the point of supporting the equipment used to move the backfill material.

Any mud or very soft backfill shall be covered with dry material to a depth that will support a dozer. If the mud cannot be made stable, then the contractor shall provide a guard to make sure no one enters the area until it has been stabilized.

If absorption of the water is permitted, then specifications will be included in Section 204.00, Special Project Specifications. Otherwise, absorption will not be permitted.

(2) Layer Placement of Fill: Fill material shall be placed in layers not to exceed one (1) foot in thickness and compacted by rolling with the earthmoving equipment used for transporting or hauling the fill material.

(a) Movement of materials will not be permitted when material is frozen or completely saturated.

Material must be in a condition that allows placement without bogging equipment down.

(b) Placement of fill or embankment will not be permitted in areas of bogs or swampy areas until those areas are drained and the sub grade of the fill prepared to receive fill materials.

(c) Preparation of surfaces to receive embankment shall be prepared by clearing all vegetative and organic materials from the site where fill materials are to be placed.

(d) When rock is used as a foundation, the foundation shall be stripped and cleaned of all overlying materials. All loose, disintegrated, or light slab portions of the rock shall be removed. In rock foundations where the rock is shattered below the foundation elevation, the shattered material shall be removed, and the foundation shall be rebuilt to meet the proposed overlying construction specifications.

When the excavated material consists predominantly of rock fragments of such size that the material cannot be placed in layers of the normal 8–12-inch thickness without crushing, pulverizing, or further breaking down the pieces resulting from excavation methods, such material may be placed in the embankment in layers not exceeding four (4) feet in depth. All rock to be placed in the embankment shall be broken into sizes not exceeding three (3) feet in maximum dimension. Larger pieces may be placed on the embankment face when permitted by the engineer. Each layer shall be leveled and smoothed with suitable leveling equipment and by the distribution of finer fragments of rock or other satisfactory material.

204.03.1 - Channels, Berms, and Dikes:

(a) Diversion channels, berms, check dams, and other minor erosion control measures shall be a part of this work and shall be constructed in accordance with the details shown on the drawings.

(b) Ditch and Berm Construction: The construction of diversion channels and berms, that are necessary for the control of drainage on the sites, shall be constructed to the template cross-section shown on the drawings. All channels or berms not designated as permanent structures shall be removed prior to final acceptance.

Minimum side slopes for channels and berms shall be two (2) feet horizontal to one (1) foot vertical or flatter. Maximum grade of the ditch bottom shall not exceed two (2) percent unless otherwise designated or directed by the engineer.

The channels shall be seeded and mulched immediately after construction of the ditch or berm is complete. Channels or berms shall be maintained throughout the life of the contract to function as constructed.

204.03.2 - Drainage Excavation: Drainage excavation shall include construction of terraces, minor channel changes, channels, water bars, diversion channels, and other minor earth drainage structures as shown on the drawings.

204.04 - Temporary Dozer Access Road: The temporary dozer access road shall be built on the flagged grade. Maximum grade shall not exceed 12 percent unless approved in writing by the engineer. The road will have a maximum disturbance width of twenty feet. Upon abandonment, the road will be water-barred directing water to the outside and revegetated.

Water bar locations will be flagged on the ground by the Engineer or Project Officer.

204.05 – (a) Area Grading: The method of measurement will be to the nearest 0.1 acre for all work completed and accepted for work backfilling highwalls and grading spoils. Horizontal measurement shall be used in the data collection.

Payment will be paid at the contract unit price bid per acre and shall be full compensation for furnishing and

(b) Landslide Grading: The method of measurement will be to the nearest 0.1 acre for all work completed and accepted for excavating landslide above the highwall. Horizontal measurement shall be used in the data collection.

Payment will be paid at the contract unit price bid per acre and shall be full compensation for furnishing and

Section 208.0 - Ditches, Terraces, and Channels

208.00 – Rock-lined channels, grass-lined channels, and terraces shall be constructed to carry surface drainage after grade work has been completed. The State will be present and help locate the channels and any terraces. General locations for anticipated channels are shown on the final views of the drawings. Design details for the channels are shown on sheet 9 of the drawings.

There are six (6) anticipated rock-lined channels required on the project. The rock-lined channels at Area 1 will be twelve (12) feet wide and three (3) feet deep and the channels at Area 2 will be ten (10) feet wide and three (3) feet deep.

The channels will be lined with five (5) ounce non-woven filter fabric. The rip-rap will be clean 6”-12” stone with larger stone over 12” (Class B) mixed in to anchor the rock in place on steep sections of the channel. Smaller stone will be rejected. The rock-lined channels total 2,330 feet in length. Soil removed from the excavation of the channels shall be deposited where it will not interfere with surface runoff into the watercourse.

Eleven (11) terraces shall be constructed to control drainage. Terrace #4 at Area 1 will serve as a road for the landowner to access a road above the backfilled highwall. All terraces shall have an outfall grade of no more than two percent.
