4.3.9 It shall be the sole responsibility of the Contractor to correctly locate and avoid all underground, on-ground, and overhead utilities, facilities and other structures and constructions, and for that purpose, shall employ all necessary precautions and methods to ensure avoidance of and damage to such constructions. In the event damage does occur, the Contractor shall notify the affected Owner and the WVDEP immediately and make or have made all necessary repairs and bear the expense thereof and resulting damage caused thereby.

4.3.10 Demolition of Structures: Buildings, mining related structures, existing ruins and foundation structures, shall be removed to the existing ground level or one foot below final grade, which operation shall include removal of concrete slabs or any other type of floors and/or walls resting upon the ground. Basement floors shall be shattered. Pits, trenches, holes or basements shall be backfilled. Coal and/or refuse spillage, concrete, cinder blocks, and foundation ruins shall be excavated and/or removed and incorporated into the fill material. Demolished concrete, cinder blocks and foundation ruins to be incorporated into the fill shall be of size less than 2 feet in any dimension. Boulders, structures, concrete pads and foundations shall be broken and buried in the deepest portion of the fill areas. Broken pieces shall not be consolidated in one area, but shall be dispersed throughout the fill areas to ensure that compaction requirements are achieved.

4.3.11 Trash, garbage, railroad ties, roofing shingles, tires, plastic, metal and other unsuitable material resulting from demolition shall be disposed of by the Contractor at his/her own responsibility and expense outside the work limits in an approved landfill, as approved by the Engineer, unless otherwise directed (disposal tickets must be furnished to WVDEP).

Bricks and stone blocks shall be disposed as per these specifications.

4.3.12 In the area where structures and buildings are demolished and removed, the removal operation shall extend to 1 foot below finished grade. The area shall then be regraded as necessary to blend into adjacent finished grades. Regrading shall be such that all areas are free draining and surface runoff will not pool or impound as directed by the Engineer.

4.3.13 Offsite Disposal or Borrow: Should offsite disposal or borrow be necessary, the Contractor shall observe the NEPA Compliance Schedule as per Section III of the Special Provisions.

4.3.14 Access Roads: Existing site access roads shall provide safe, all-weather access to the site.

These existing roads, including stoned and paved roads, shall be maintained during construction and left in a better than or equal to condition. The Contractor is responsible for locating and avoiding all underground and overhead utilities and constructions during access road grading and maintenance.

4.3.15 Gravel Road Rehabilitation Stone: Stone to be placed for “Gravel Road Rehabilitation Stone” shall conform to the detail as shown on the plans. The rehabilitation stone location is shown on the plans and as approved by the Engineer.

4.3.16 Separation Fabric: Separation Fabric shall be placed on a prepared subgrade prior to placement of surfacing and resurfacing stone. In areas that will not support the stone due to soft conditions, Separation fabric will be required as directed by the Engineer.

4.3.17 Fence: When existing fences are encountered within or near work limits, which by necessity of the construction activities require their dismantling, the Owner shall be consulted to secure their approval for the need of fencing, as well as determination as to whether temporary and/or permanent fencing will be utilized. The Contractor will be required to re-construct fence lines of any type located within the project area. Temporary fencing shall be installed along the alignment selected by the Owner, with sufficient material included to alter said alignment as may be required to accommodate the construction activity. Similarly, approval for the use and location of permanent fencing shall be obtained from the Owner well in advance of construction. Typically, permanent fencing shall be compatible with that which existed and installed in the location of the existing fence. Existing fences outside the construction limits and near or adjacent to the project area are to remain undisturbed in place. Any fencing damaged outside the work limits shall be repaired or replaced at the expense of the Contractor, to a condition equal to, or better than, its original condition. Wire for permanent or temporary fencing shall be 15 ½ gauge 4 pronged barbed wire unless otherwise required.

4.3.18 Property Markers: Any existing property markers disturbed or removed during construction activities shall be replaced accurately and to an “as good as” or “better than” condition and as approved by the WVDEP. This work will be paid under Section 2.0 Construction Layout of these Specifications.

5.0 EROSION & SEDIMENT CONTROL

5.1. Description

This item shall consist of furnishing all materials, equipment, labor and incidentals necessary for the installation of Straw Wattles, Sediment Control Barrier Structures (e.g.

silt fence or super silt fence), Check Dams and Stabilized Construction Entrances as designated in the Drawings. Additional quantities may be added at the discretion of the

WVDEP.

The CONTRACTOR shall be given a NPDES Permit with an approved erosion and sediment control plan at the pre-construction meeting. This plan shall include measures to be utilized for temporary and permanent sediment and erosion control. This plan shall also include the measures as outlined herein. The NPDES approved plan does not relieve the CONTRACTOR of his/her responsibility to be in compliance with any and all permits. All costs associated with meeting the federal and/or state regulations shall be the sole responsibility of the Contractor.

NOTE: Sediment Control Measures shall be required on the perimeter of the project site for sediment control in accordance with the NPDES requirements. The silt fence for sediment control shall be installed before any construction work begins. This fence shall remain and be maintained during the entire construction process. Erosion control shall be placed on regraded outslope areas concurrent with construction and prior to revegetation.

The following are the minimum requirements of the NPDES Permit and/or the NPDES BMP Manual.

VEGETATIVE PRACTICES

Except as noted below, stabilization measures shall be initiated as soon as practicable in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than fourteen days after the construction activity in that portion of the site has permanently ceased.

Where the initiation of stabilization measures by the fourth day after construction activity temporarily or permanently ceases is precluded by snow cover, stabilization measures shall be initiated as soon as conditions allow.

Where construction activity will resume on a portion of the site within 14 days from when activities ceased, (e.g., the total time period that construction activity is temporarily halted is less than 14 days) then stabilization measures do not have to be initiated on that portion of the site by the seventh day after construction activities have temporarily ceased.

Areas where the seed has failed to germinate adequately (uniform perennial vegetative cover with a density of 70%) within 30 days after seeding and mulching must be reseeded immediately, or as soon as weather conditions allow.

Diversions must be stabilized prior to becoming functional.

EROSION & SEDIMENT CONTROL CONSTRUCTION SEQUENCE

Install stabilized construction entrance as shown on site plans.

Install perimeter sediment control devices as shown on site plans.

Clear and grub site.

Provide sediment control for any topsoil stockpiles.

Commence rough grading of site. Continue to maintain and inspect all erosion and sediment controls.

Fine grade site.

Install additional erosion and sediment controls as shown on site plans.

Permanently seed and mulch all disturbed areas within 7 days of reaching final grade and install erosion control wattles.

Upon completion of project including adequate stabilization, remove all remaining erosion and sediment controls.

5.2. Materials

5.2.1 Sediment Control Barriers: silt fencing materials and installation shall meet all applicable requirements of the manufacturer’s specifications and the typical details.

5.2.2 Erosion Control Wattles: ACF Environmental straw wattles or approved equals, shall be installed at locations shown on the plans. Straw wattles shall be 12 inches in diameter and follow installation of Specification 5.4.3. Straw wattles shall consist of an internal fill material of compressed straw fibers and an exterior encasement of a photodegradable polypropylene netting.

5.2.3 Stabilized Construction Entrances shall consist of coarse 3-6 inch stone over a geotextile fabric.

5.2.4 Rock Check Dams: Rock check dams shall be required at the locations as shown on the plans. The rock check dams shall be constructed with 3”-6” stone.

5.3. Maintenance

5.3.1 During the course of the project, sediment control barriers shall be maintained in sound condition and accumulations of silt which may threaten their effectiveness shall be removed. Silt removed from the sediment control structures shall be taken to an approved disposal area.

5.3.2 The Stabilized Construction Entrance shall be maintained in a condition that will prevent tracking or flowing of sediment onto access roads. This may require periodic top dressing with additional stone as conditions demand and repair and/or cleanout of any measures used to trap sediment. All sediment spilled, dropped, washed or tracked onto public rights-of-way must be removed immediately.

5.3.3 Wheels on all vehicles shall be cleaned to remove sediment prior to entrance onto public rights-of-way. If washing is required, it shall be done on an area stabilized with stone and which drains into approved sediment trapping device. If the street is washed, precautions must be taken to prevent muddy water from running into waterways or storm sewers.

5.3.4 At a minimum, all erosion and sediment controls on the site will be inspected at least once every seven calendar days and within 24 hours after any storm event of greater than 0.5 inches of rain per 24-hour period.

5.3.5 All controls should be cleaned out when sediment reaches one half the sediment capacity of that control.

5.3.6 Inspection and maintenance records must be kept onsite.

5.4. Installation

5.4.1 Silt Fence: Fence posts shall be a minimum of 48" long driven 16" minimum into the ground. Where ends of geotextile fabric come together, they shall be overlapped, folded and stapled to prevent sediment bypass. Silt Fence shall be inspected after each rainfall event and maintained when bulges occur or when sediment accumulation reached 50% of the fabric height.

5.4.2 Stabilized Construction Entrance: A stabilized construction entrance shall be required at the access point of the construction site. The stabilized construction entrance shall consist of filter fabric and a minimum of six (6) inches of 3” to 6” stone. The stone entrance shall be a minimum of seventy (70) foot long and twelve (12) foot in width.

This stone construction access must conform to the detail drawings shown in the plans.

5.4.3 Straw Wattles: A trench shall be excavated to a depth of 1/3 of the diameter of the wattle. Lay the first Straw Wattle snugly in the excavated trench. No daylight should be seen under the Wattle. Pack soil from trenching against the Wattle on the uphill side.

When installing running lengths of Straw Wattles, butt the second Wattle tightly against the first. DO NOT overlap the ends. Stake the Straw Wattles at each end and four foot on center. For example:

A twenty-five (25) foot wattle uses 6 stakes.

A twenty (20) foot wattle uses 5 stakes.

A twelve (12) foot wattle uses 4 stakes.

Stakes should be driven through the middle of the Wattle, leaving 2 - 3 inches of the stake protruding above the Wattle. A heavy sediment load will tend to pick the Wattle up and could pull it off the stakes if they are driven down too low. It may be necessary to make a hole in the Wattle with the pick end of your mattock in order to get the stake through the straw. When Straw Wattles are used for flat ground applications, drive the stakes straight down; when installing Wattles on slopes, drive the stakes perpendicular to the slope.

Drive the first end stake of the second Wattle at an angle toward the first Wattle in order to help abut them tightly together.
