1.0 LOCATION / SITE DESCRIPTION

The project is located on the Eastern side of County Route 27, Kuhns Run Road and approximately 6 miles Southwest of Fairmont within Marion County, West Virginia.

The project consists of an existing slip area, a collapsed portal, subsidence depressions, multiple seep areas, and spoil area that needs regraded.

All these features are posing a risk to public safety and need to be repaired. The objective of this project is to excavate and seal the portal, repair the slip area to a stable condition, regrade the spoil area to provide positive drainage, fill the subsidence areas to provide a stable area and positive drainage, collect all underground and surface drainage and convey it to a stable discharge location. These efforts should allow for the site to be more stable and safer for the public and the livestock that is present on the site.

Directions to Site:

From the Exit 132 of I-79, take US Route 250 south for 0.4 miles. Turn right onto County Route 73/Middletown Road. Travel 0.9 miles and turn right onto County Route 58/Industrial Park Road. In 1.6 mile turn left onto county route 58/1/Manley Chapel Road. Continue 1.6 miles and turn left onto County Route 27. The site is 0.7miles on County Route 27.

Approximate GPS Coordinates for Slip Repair is:

39.431826°, - 80.238480°

Approximate GPS Coordinates for Portal #1:

39.430156°, - 80.240414°

2.0 SCOPE OF WORK

The Work consists of furnishing all labor, plant, power, equipment, supplies, and performing all operations necessary for the completion of the project. The Contractor shall perform all operations necessary for:

Mobilization and Demobilization Survey and Construction Layout Installation and Maintenance of Erosion and Sediment (E&S) Controls Temporary Access Road Construction Quality Control Site Preparation, including Clearing and Grubbing Unclassified Excavation / Regrading / Soil Drying Traffic Control, where required Installation of a Culvert under the County Route 27 Installation of Channels Installation of Modified Wet Mine Seal Slip Repair Conveyance Pipe Installations Gate Installation Repaving and Refinishing of Existing Paved Road, if damaged during the Work Gravel Road / Laydown Rehabilitation Revegetation Final Site Cleanup and Removal of E&S Controls

Specifically, the Contractor will be installing their E&S Controls, establishing their Work area and laydown area, clearing, and grading the site as needed to provide space to Work, installing a temporary access road, and any other applicable Site Preparation.

The Contractor will excavate and repair the slip area as shown on the plans. This will include toekey benches, bonding benches, chimney drains, and replacement of soil to meet the design finish grades.

Contractor to install one (1) modified wet mine seal in accordance with the Plans to drain Mine Portal #1.

Traffic Control will be implemented by the Contractor. Contractor is limited to only obstructing one lane of the road at a time – and in compliance with the Traffic Control Section of these Specifications. The expectation is for the Contractor to limit lane closures to the greatest extent practical. The expectation is also for the Contractor to not close lanes – whenever at all practical – during typical rush hour traffic periods.

During the Work, the Contractor is to exercise caution in not disturbing structures or trees to remain.

The Contractor is to repair or reconstruct (full depth) any pavement damaged during the Work by the Contractor to a quality consistent with these Specifications and to a quality at least what was present before the Work started, at the Contractor’s expense, except as otherwise specified or approved. The expectation is that, if the pavement is damaged, that the pavement would be, at a minimum, milled down at least 2” and resurface areas as deemed necessary by the engineer – patches are unacceptable. If damage protrudes into the base or aggregate layer of the existing asphalt, then a full depth repair will be necessary. This will be determined as directed by the Engineer. If nothing is damaged during the Work, then no replacements would be necessary.

Contractor to install farm gates consistent with the Plans.

Contractor is responsible for leaving the site and surrounding area in original condition or better. This includes refurbishing the existing access road to at least as good a condition as was present before the Work started – and additional stone is provided in the estimate for making it nicer than what was present originally. This also includes picking up and disposing of any trash or litter the Work generates in accordance with these Specifications.

Contractor will IMMEDIATELY clean any mud off roadways that the State reasonably believes to be project related.

Contractor is responsible for engaging in soil disturbance only within the Limits of Disturbance shown on the Plans.

The Contractor shall also be responsible for surveying, including establishing construction baseline, measuring, and developing all completed quantities on the job, and the ordering, purchase and delivery of any and all materials required for construction or required for development of support areas. The Contractor shall perform all other operations as incidental to the program as specified herein. The Contractor is responsible to verify all surveying, measurements, estimates, or any other information provided by the State for accuracy.

3.0 QUALITY CONTROL

3.1 Description

This Work shall consist of testing for verification that the materials supplied, and the work performed are in accordance with these Specifications. Work shall be performed to the satisfaction of the State to be considered complete.

3.2 Materials

The Contractor shall submit a minimum of two (2) copies of shop drawings, catalog cuts and material certifications (as applicable) to the Engineer for all offsite materials to be incorporated into the Work. At least 1 copy submitted must be electronic. Written approval from the Engineer will be required prior to incorporation of these items into the Work.

The Contractor shall submit at least two (2) copies of the results of all tests conducted on in-situ material, concrete, and grout to be used in this project. At least 1 copy must be electronic.

Test sampling of concrete shall be in accordance with ASTM C172. Temperature testing of concrete will be in accordance with ASTM C1064. Slump testing of concrete will be in accordance with ASTM C143. Air content of the concrete shall be tested according to ASTM C231, ASTM C173, or ASTM C138. Concrete cylinders formed for compressive strength testing shall be formed in accordance with ASTM C31. Concrete compressive strength testing shall be in accordance with ASTM C39. Four concrete test cylinders shall be made and tested: one test cylinder shall be tested 4 days age, one test cylinder at 14 days age, one test cylinder shall be tested at 28 days age, and one cylinder shall be held as a spare. Concrete must have a compressive strength of at least 4,000psi within 28 days, a slump of 1-4 inches, an air content of 6-7.5%, and a temperature of 50°F-90°F at pouring to be acceptable, unless otherwise specified in the Plans or these Specifications. Concrete used in road crossings, such as headwalls or wingwalls for a culvert crossing a road, must meet the requirements of Section 601 of the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition, and the MM-109. In the event of a conflict between these Specifications, the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition or the MM-109 then the most stringent requirement shall prevail. In the event of a conflict between the above that is more fundamental, such as what material to use or what construction methods to employ, then the order of priority would be the MM-109 (for roads only), then the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition (for roads or bridges only), and then these Specifications. Outside of work on, under, or near roads and bridges, these Specifications prevail entirely. Notwithstanding the above, a conflict in one requirement does not relieve the Contractor of abiding by all other requirements in these Specifications.

For ease of reference, the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition can be found at the below:

https://transportation.wv.gov/highways/TechnicalSupport/specifications/Documents/20 23_Standard_%2812-16-22%29.pdf

These requirements apply to both pre-cast concrete and concrete that is cast in place.

Unacceptable concrete must be replaced at the Contractor’s expense. Custom concrete mixes outside of these tolerances can be approved by the Engineer on a case-by-case basis. The State reserves the right to reject concrete based on a visual inspection without waiting on testing results.

Test sampling and compressive strength testing of grout shall be in accordance with ASTM C1019. Slump testing of grout shall be in accordance with ASTM C143. Grout must have a compressive strength of at least 2,000psi within 28 days and a slump of 8- 11 inches to be acceptable, unless otherwise specified in the Plans or these Specifications.

Unacceptable grout must be replaced at the Contractor’s expense. Custom grout mixes outside of these tolerances can be approved by the Engineer on a case-by-case basis. The State reserves the right to reject grout based on a visual inspection without waiting on testing results.

Test sampling of Controlled Low Strength Material (CLSM) – also known as flowable fill – shall be in accordance with ASTM D5971 and ASTM D4832. CLSM compressive strength testing shall be in accordance with ASTM D4832. CLSM must have a compressive strength of at least 2000 psi within 28 days. CLSM used for road crossings must have a pH of 5.0-13.0 and must meet the requirements of Section 219 of the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition and the MM-109, as applicable. In the event of a conflict between these Specifications, the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition, or the MM-109, then the most stringent requirement shall prevail. In the event of a conflict between the above that is more fundamental, such as what material to use or what construction methods to employ, then the order of priority would be the MM-109 (for roads only) then the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition (for roads or bridges only), and then these Specifications. Outside of work on, under, or near roads and bridges, these Specifications prevail entirely. Notwithstanding the above, a conflict in one provision does not relieve the Contractor of abiding by all other requirements in these Specifications. Unacceptable CLSM must be replaced at the Contractor’s expense.

Custom CLSM mixes outside of these tolerances can be approved by the Engineer on a case-by-case basis, subject to the above MM-109 and WVDOT Standards above. The State reserves the right to reject CLSM based on a visual inspection without waiting on testing results.

At a minimum, the pipe / fill compaction tests will include moisture content and density tests of the soil in accordance with the provisions of ASTM D698 (Standard Proctor) field density tests following compaction. A new Standard Proctor will be run when soil type changes occur on site and/or at the direction of the Engineer or State representative.

Soil tests shall determine the optimal additives required for areas of soil disturbance to be fully re-vegetated (3 tons per acre preferred minimum). Normally, this includes – at a minimum – soil pH test results as well as available nutrients within the soil, including, at a minimum: nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (MG), and Sulfur (S). At a minimum, the soil testing report will recommend what soil amendments in which concentrations are ideal for regrowth. If problems with re-vegetation occur, additional, more specialized tests may be required to be performed at the Engineer’s discretion and the Contractor’s expense.

Limestone and Sandstone shall be subjected to a Sodium Sulfate test in accordance with AASHTO T104. All stone shall have a maximum weighted loss of twelve (12) percent when subjected to five (5) cycles of the Sodium Sulfate Soundness Test – ASTM C88 (ASTM C88-05 Standard Test Method for Soundness of Aggregates by Use of Sodium Sulfate or Magnesium Sulfate), as modified by the American Association of State Highway and Transportation Officials (AASHTO) T-104. All Stone shall be commercially supplied and shall be tested for calcium carbonate.

Limestone shall be tested for calcium carbonate equivalency which must be 70% or greater and be certified as such.

Sandstone shall be certified to be non-acid producing. Sandstone to be sound, non-acid producing, durable, non-calcareous sandstone from a State approved source. Shale is not acceptable. The sandstone shall consist of particles of clean, hard, tough, durable rock, free from adherent coating. The State reserves the right to reject sandstone based on a visual inspection without waiting on testing results.

Note that the WVDOT Standard Specifications for Roads and Bridges, 2023 Edition and the MM-109 (if applicable) specify quality control and testing procedures that ARE REQUIRED for any applicable asphalt replacement repaving, shoulder stone, guardrail replacement, etc. The Contractor is to ensure these are implemented, that materials and installations permanently installed meet or exceed all required tests, and the Contractor shall provide the results to the State and the WVDOH for record.

4.0 SITE PREPARATION

4.1 Description

Clearing and Grubbing - Work performed under this section shall include the removal and disposal of all trees, stumps, shrubs, and any other vegetation along with wood, debris, or garbage of any nature. This includes those areas specified below, shown on the Plans, and any other areas as approved by the State via Change Order. This work shall also include the preservation from damage for all vegetation, utilities, or any other object not being specifically removed according to the Specifications and Plans.

Additionally, this work shall include stripping and stockpiling topsoil from the construction area, keeping it separated from other stockpiled soil, and using the topsoil for soil cover and revegetation at the end of the construction.

Demolition of Structures - This Work shall consist of complete demolition and removal of such buildings, mining related structures, equipment and materials, existing ruins and foundation structures and existing AML structures and systems, as are specifically designated on the Plans for removal or encountered during construction, except as is otherwise specified. Demolished concrete and cinder block structures and foundation ruins may be disposed of off-site. Note that any steel or burned (if authorized) wood remnant must still be removed from the site. All on-site garbage (as well as all other debris of any type and quantity), mining equipment, and metal structures encountered shall be removed from the site to an off-site disposal area in accordance with these Specifications to a Landfill approved by the State to accept the applicable waste type.

Certified disposal weight tickets shall be provided to the WVDEP. The Contractor is advised to perform a thorough site reconnaissance to quantify all garbage designated for removal prior to submitting a bid.

Asbestos Material Identification and Removal (if present) - This Work shall consist of a Contractor-provided Competent Person – as defined by Title 29, Subtitle B, Chapter XVII, Part 1926 of the CFR Code – performing a thorough search of all existing structures on the project to ensure that there are no asbestos materials present. If any areas are suspected of containing asbestos, then an inspection would need to occur – at the Contractor’s expense – by a company possessing a valid, current Asbestos Contractor License in the State of West Virginia. Each on-site representative of the company performing the asbestos survey or mitigation would need to be a Licensed Asbestos Contractor in the State of West Virginia. If asbestos was found, an estimate for removal and proper disposal would need to be obtained by the Contractor and submitted for the Engineer’s approval.

At that point, the Contractor would be responsible to perform all notifications as required by all Federal and State law – particularly NESHAP as outlined in Title 40, Chapter I, Subchapter C, Part 61, Subpart M of the CFR Code. No work would be allowed at the location of the asbestos until the removal process was completed. No asbestos mitigation or removal is anticipated for this Work – if the Contractor determines asbestos is present and subsequently receives a positive test for asbestos, a Change Order would be negotiated with the State for the proper mitigation to occur through the Contractor. All mitigation by the Contractor (or their Sub-Contractor) would need to be in accordance with all Federal, State, and Local laws.

Materials and Equipment Storage - The Contractor shall obtain approval from the Engineer for proposed materials and equipment storage areas prior to use. Refueling or fuel storage should not occur within 100ft of a wetland, water body, stream, or ditch leading into the same – see additional requirements for fuel storage in the “Spill Containment Area” below. Areas utilized shall be restored to an “as good as” or “better” condition than existed prior to construction or shall otherwise be reclaimed as directed or approved by the Engineer.

Temporary Access Road Construction - Temporary access roads constructed to gain access to, travel between or otherwise required for equipment/vehicular site access shall be kept to a minimum and only constructed where necessary upon approval from the WVDEP, where applicable. If the Contractor constructs such travel routes, they shall be reclaimed and revegetated according to Section 6 upon completion of the construction activities, as deemed necessary by the WVDEP. Any additional access shall require the Contractor to obtain written permission from the respective landowner. The existing access roads shall be fine graded to provide positive drainage. Ditches and road crossing shall be installed as directed by the Engineer.

Any re-grading necessary for the construction of the Access Road will be incidental to the cost of the work described herein.

Final grading, stabilization, and providing final drainage control for existing access roads shall be performed after reclamation operations for the project have been completed.

Permanent Fencing – Any fencing required to be moved and replaced due to construction activities or newly proposed as shown on the plans. Permanent fencing shall be placed at the completion of construction.

Temporary Fencing –Temporary fencing shall be utilized to remove livestock access to the project site (typically wooden posts and T-posts with wire-mesh barriers in-between keeping livestock off the Work area). It is the Contractor’s responsibility to install, maintain, and remove this fencing on an as-needed basis – or as the State indicates – to remove hazards to the public, livestock, or damage to the project site over the course of the Work. Temporary fencing will be removed by the Contractor prior to Final Inspection, unless indicated otherwise by the State.

Spill Containment Area - Spill containment measures shall be used for fuel and lubricant storage areas. All containers, barrels, buckets, cans, etc., are to be legally disposed of offsite. Used lubricants are to be disposed of according to State law to minimize pollution to the local surface and ground water supplies. Spills are the responsibility of the Contractor and need immediate clean up and maintained at no expense to the State. Fuel tanks manufactured with secondary containment are desirable; the minimum secondary containment shall be 110 percent. Contractor required to have a spill kit, including sorbent pads, at the Spill Containment Area. Spill Containment Area should be at least

100ft from any wetland, water body, stream, or ditch leading into the same. In the event of a spill, the Contractor is required to call the emergency spill line (ph. 1-800-642-3074).

Farm Gate – Farm Gate shall be installed at the location(s) shown on the Plans, and / or as directed by the State. Farm Gate is to be placed and installed such that it adequately restricts traffic through the specified area on the Plans. Farm Gate shall be placed at the completion of the Work and shall comply with the details shown in the Plans.
