Article 205.01 Description

This work shall consist of the compaction of earth fill area(s) or mine refuse disposal area(s) and cover soil by depositing, placing and compacting mine refuse and earth fill areas and all cover soil over mine refuse except the top 300 millimeters (12 inches) of cover soil.

Article 205.02 Equipment

Equipment shall meet the requirements of the following Articles of Section 1100 - Equipment:

Item Article

(a) Disk Harrow 1101.02

(b) Tamping-Type Roller shall consist of one or more cylindrical sections having studs or feet projecting not less than 162.5 millimeters (six and one-half inches) from the surface of the drum. The number of tamping feet and the area of feet shall be such that the pressure on a single row of feet approximately parallel to the axis of the drum is not less than 1.38 kPa (200 p.s.i.) when supporting the full weight of the roller.

Article 205.03 Preparation of the Subgrade for Earth Cover

Before fill material is placed, all clearing, tree removal and hedge removal over the fill area shall be performed as provided in Section 201 of the Special Provisions, and the top 150 millimeter (six inches) of the existing ground surface shall be disked and then compacted to the satisfaction of the Engineer. If the fill areas are being constructed during the winter, snow and ice shall be removed from the areas to be covered by fill material. Fill material shall not be placed on frozen earth. When construction is resumed after any winter shutdown period, the top 200 millimeters (eight inches) of all partially completed fill areas shall be reprocessed and compacted to the minimum specified density prior to placing more fill material in the areas.

When earth fill area(s) are to be constructed on hillsides or slopes, the existing slopes shall be plowed deeply; or if additional precautions for binding the fill materials together are justified, steps shall be cut into the existing slopes before the construction of the fill area is started. If the existing surface is within 150 millimeters (six inches) of the elevation of the subgrade or the completed earth surface, it shall be plowed or otherwise broken up to a depth of not less than 150 millimeters (six inches).

When the mine refuse disposal area(s) has been graded to the subgrade shown in the plans, MINE REFUSE TREATMENT - LIMESTONE shall be performed on the subgrade in accordance with Section 255 of these Special Provisions. The subgrade shall then be compacted with a roller until the tamping feet of the roller penetrate not more than 50 millimeters (two inches) into the subgrade or to the satisfaction of the Engineer.

Article 205.04 Placing Earth Cover Material

Fill material shall be placed in accordance with the following requirements:

(a) General. Fill areas shall be constructed of materials that will compact and develop a stability satisfactory to the Engineer. No sod, frozen material or any material which, by decay or otherwise, might cause settlement, shall be placed or allowed to remain in the fill areas. Fill areas shall be constructed to the height and width deemed necessary to provide for shrinkage during compaction. Upon completion, they shall conform to the lines, grades and cross sections shown on the plans, with proper provision for shrinkage. When mine refuse disposal areas are constructed of crushed material, broken concrete, stones, or rocks and earth, such materials shall be well distributed, and sufficient earth or other fine material shall be incorporated with them when they are deposited to fill the interstices and provide solid embankment. No rock, stones or broken concrete more than 150 millimeters (six inches) in largest dimension shall be permitted within a vertical distance of 300 millimeters (12 inches) below the surface of the subgrade.

Pieces of concrete, not exceeding two square feet for any area of surface, and large rocks and boulders may be placed in fills without being broken up, provided they are well embedded, and interstices filled with smaller pieces or smaller material in a manner to give a density satisfactory to the Engineer. The layers of the smaller pieces or smaller material shall not exceed 300 millimeters (12 inches) in depth.

So far as practicable, each layer of material shall extend the entire length and width of the mine refuse disposal area. The material shall be leveled by means of bulldozers, blade graders or other equipment approved by the Engineer. Each layer shall be not more than nine inches thick when in loose condition, shall be uniform in cross section, and shall be thoroughly compacted before the next layer is started.

The use of dragline excavators or similar equipment which excavate and deposit material in large unit masses will not be permitted, unless all materials excavated in this manner are spread as provided herein and compacted as required in Article 205.05 of these Special Provisions, or as directed by the Engineer.

Article 205.05 Compaction

Each layer of mine refuse or earth fill material shall be disked sufficiently to break down oversized clods, mix the different materials, secure a uniform moisture content, and ensure uniform density and compaction. Disking may be omitted if the fill consists of non-cohesive material.

All lifts of earth fill or mine refuse will be considered compacted when the tamping feet of the roller penetrates not more than three inches into a nine-inch lift or one-third of the depth of the layer being placed. If, after making four passes the required compaction is not yet achieved, the Engineer shall take necessary steps to analyze and test the soil conditions. If tests indicate that the material is above 115 percent or below 90 percent of the standard optimum moisture content then the material shall be dried or wetted as necessary to fall within this range. The layer shall then be recompacted until the desirable results are obtained or an additional four passes are made. If the material is determined to be within the specified optimum moisture content range and four passes have been made, no further compaction efforts are necessary.

All lifts of cover soil shall be compacted except the top 300 millimeters (12 inches). Compaction will not be required on the top 300 millimeters (12 inches) of cover soil.

The fill areas shall be sprinkled with water when it is necessary to increase the moisture content of the soil to permit the fill areas to be constructed to the densities indicated above.

Compacting equipment and compacting operations shall be coordinated with the rate of placing the earth materials so that the required density is obtained.

Article 205.06 Maintaining and Trimming Embankments

The Contractor shall replace, at his own expenses, any portions of the fill areas which have been damaged or displaced by reason of carelessness or negligence on his part. After the fill areas have been constructed as specified herein, their sides shall be trimmed to the proper slopes where required, and they shall be maintained by the Contractor to the proper elevation and cross-section until they have been accepted.

Article 205.07 Method of Measurement

Mechanical compaction will not be measured for payment.

Article 205.08 Basis of Payment

Compaction and any additive or water applied will not be paid for directly, but shall be considered as incidental to the various items of excavation, and the cost of their construction shall be included in the unit prices for these items.

(12) Common Weed Names & Percentages

(13) Percentage of Total Inert Matter

(14) Noxious Weeds and Percentages (if any)

A ten-percent tolerance will be allowed for each specified pure live seed species in the total seed mixture. If test results indicate insufficient pure live seed of any species, additional pure live seed of the same species shall be added prior to seeding, to correct deficiencies to within the ten percent tolerance allowable.

If test results indicate the presence of an Illinois noxious weed, or the seed mixture is found unacceptable by reason of any other defect that in the judgment of the Engineer cannot be corrected, the Contractor shall obtain a new supply of the specified seed mixture. Any areas seeded with an unacceptable seed mixture shall be destroyed, by preparing a new seed bed and reseeding. No additional compensation will be allowed for correcting deficiencies to within the allowable tolerance, for obtaining a new seed supply if required, or for reseeding.

Seeds may be sampled at destination on a random basis and tested for comparison with certification and compliance with the Specifications. If deviations are found, the results will be reviewed to determine whether the material is acceptable for use. Major deviations may result in a requirement that each lot of material from the source in question be sampled, tested and approved by the Illinois Department of Agriculture before further use.

The no-till (zero-till) areas may or may not be mowed prior to or after no-till (zero-till) seeding according to the Engineer's discretion. If the Engineer determines mowing is necessary, it will be measured and paid for according to Articles

250.09 and 250.10, respectively. At no time will the seeder be used as a mulch stabilizer in conjunction with seeding or alone.

(e) Direct Vegetation. If seed bed preparation is required on direct vegetation areas, agricultural ground limestone and fertilizer nutrients shall be applied prior to seeding and according to these specifications. If seed bed preparation is not required or if the Engineer determines it is impractical, the agricultural ground limestone and fertilizer nutrients shall be applied according to the Engineer's discretion.

Article 250.05 Seed Bed Preparation

Seed bed preparation cannot be performed sooner than 14 days prior to seeding. Seed bed preparation will not be required when no-till seeding or Incorporation - Limestone and Mulch is specified. The prepared surface shall be free of rills, vegetative clumps, or other debris. Rocks and objects larger than 6 inches shall be removed. No seed shall be applied until the seedbed has been approved by the Engineer. The final 24 inches of fill shall not be compacted but remain loose.

Article 250.06 Seeding Methods

Apply Excelsior blanket and mulch on the same day the that the seed is sewn. No seed shall be sewn in wind conditions greater than 10 mph. Equipment shall be calibrated to deliver a uniform density and shall cover the entire area.

Interseeding, Native seed species and some Wetland species may require to be sewn by hand due to the small size of the seed. Only mechanical equipment such as a Rangeland drill capable of delivering the seed size uniformly will be used. Hand seeding each species individually is the alternative.

Article 250.07 Seeding Dates and Seed Mixture for Permanent Seeding

Seeding will not be allowed when the wind speed is 10 miles/hour or greater. Seed bed preparation may be allowed by the Engineer prior to seeding dates at his/her discretion. The Contractor may submit a written request to deviate from the Contract seeding dates, but germination success and reseeding guarantee remain. Temporary seeding for erosion control SEEDING CLASS 7, initiated at the direction of the ENGINEER, shall be performed according to the Standard Specifications for Road and Bridge Construction Article 250.

SOUTHERN ILLINOIS (South of Routes 72/74) Spring seeding dates shall be April 1st to May 1st , and fall seeding dates shall be September 1st to September 15 for the following seeding mixes.

PURE LIVE SEED

SEED VARIETIES lb./ac.

Orchard Grass - 5 Redtop - 5 Rape - 5 Long Headed Coneflower - 5 Birdsfoot Treefoil - 5 Little Bluestem - 5 Big Bluestem - 5 Black Eyed Susan - 5 Sideoats Gramma - 10 Canada Wild Rye - 10 Alsike Clover, Ladino or White Clover - 10 Alfalfa - 10 Perennial Rye - 10 Cereal Rye - 20

TOTAL 110

Replace Cereal Rye with 20 lbs. of Spring Oats and 10 lbs. of Buckwheat for Spring Seeding All Legumes such as alfalfa and clovers shall be inoculated per the recommendations of that inoculant producer prior to seeding. Operations must be completed within 24 hours of inoculation.

Temporary Seeding -This provision is applicable should the Contractor fail to perform permanent seeding within the dates specified. Temporary seeding shall be required to provide a temporary vegetative cover until the next term of permanent seeding dates and shall be performed by the Contractor at his/her own proper cost and expense. The Engineer shall submit in writing to the Contractor a proposed temporary seeding mixture, specifying the seed varieties and their respective rates on a pounds/acre of pure live seed basis. Vegetation resulting from the temporary seeding shall be destroyed as part of the seed bed preparation for future permanent seeding.

Reseeding Guarantee.

The Contractor is required to guarantee the results of the permanent seeding for one year after the date of seeding. If the Engineer determines that vegetation on any area is unacceptable, the Contractor shall be required to reseed that area during the next term of permanent seeding dates, at the Contractor's own proper cost and expense.

Unacceptability will be based on:

(1) Seed test failure (Article 250.02).

(2) Using unacceptable equipment in performing seeding.

(3) Failure to perform seeding as specified, i.e., missing areas during seeding, improper seed bed preparation, etc.

(4) Failure to perform mulching as specified, i.e., applying too much or too light application in some areas, using unacceptable mulch, etc.

Subsequent Reseeding.

Any area reseeded once by the Contractor will be inspected within six months after reseeding to determine if germination has occurred. If subsequent reseedings are required of the same area(s), through no fault of the Contractor, the Contractor shall be compensated for such subsequent reseeding at unit bid prices for each applicable pay item.

NPDES Compliance (This section is added to ensure compliance and provide guidance on how the Contractor shall perform work while meeting conditions of the NPDES Permit.)

1. Conditions created by or for the convenience of the Contractor’s operations will not exclude or release the requirements of NPDES conditions or of those in IDOT Article 280.

2. Work shall be coordinated with the Engineer such that completed slopes and areas of permanent seeding will be seeded and mulched. Under no circumstances shall the Contractor prolong Final grading and shaping. All seeding, permanent or temporary, shall be completed when determined by the Engineer to do so. More than one mobilization of seeding equipment may be necessary and at no additional cost to the Department.

3. Seeding and Erosion Control items related to NPDES regulations will be governed by applicable sections of IDOT Standard Specifications January 1, 2022, Article 105.

Article 250.10 Basis of Payment The cost of seed testing and any temporary seeding or reseeding will not be paid for separately but shall be considered incidental to the cost of SEEDING. Seeding, Mulch, and Mowing shall be measured and paid by the area in Acres. Nutrients shall be paid by the pounds of actual nutrient.

SECTION 280: TEMPORARY EROSION AND SEDIMENT CONTROL –

(revise the following articles as indicated)

Article 280.03 Construction Requirements - (delete and replace with the following)

Erosion and sediment control measures as indicated in the Storm Water Pollution Prevention Plan, or as directed by the Engineer shall be installed on the project site prior to beginning any construction activities which will potentially create erodible conditions. Erosion and sediment control devices shall be in place and approved by the Engineer as to proper placement and installation prior to beginning other work. Erosion and sediment control protection for Contractor borrow pits, equipment storage sites, plant sites, haul roads, and other sites shall be installed by the Contractor and approved by the Engineer prior to beginning construction activities at each site.

The Engineer has the authority to limit the surface area of erodible earth material exposed by clearing and grubbing, excavation, borrow and embankment operations, and to direct the Contractor to provide immediate permanent or temporary erosion and sediment control measures upon finding an incidence of non-compliance with the Storm Water Pollution Prevention Plan. The Contractor shall incorporate all permanent erosion and sediment control features into the project at the earliest practicable time to minimize the need for temporary controls.

The Contractor is encouraged to carefully plan his/her operation so that final gradework is performed as close as possible to the seeding dates specified in the contract to minimize the chances of erosion from areas affected by construction.

Areas where construction activities have ceased for more than 14 consecutive days may require site stabilization practices which may include temporary seeding, mulching, or installation of excelsior blanket, straw bales, silt fence, diversion ditches, vegetative buffer strips and/or geotextiles. For purposes of this Section, the end of construction activities on affected land areas is defined as the time when seedbed preparation has been concluded.

In case of repeated failure on the part of the Contractor to take steps prescribed by the Engineer to control erosion and sediment, the Engineer reserves the right to employ outside assistance or to use his/her own forces to provide the necessary corrective measures. Such incurred direct costs plus project engineering costs will be charged to the Contractor and deducted from any compensation due, or which may become due the Contractor under the contract.

Article 280.08 Basis of Payment - (add the following)

Maintenance of temporary erosion and sediment control systems including repair of the various systems, removal of entrapped sediment and cleaning of any silt filter fabric, will be considered incidental to the above pay items for temporary erosion control systems. The sediment shall be removed as directed by the Engineer during the contract period and disposed of on-site as directed by the Engineer.
