24002AMLBAML (AML) RECLAMATION PROJECT

PIKE COUNTY, KENTUCKY

Written Location Directions: LATITUDE: 37.5836° N, LONGITUDE: 82.1936° W. The project site is located along KY 319. From the intersection of US 23 and US 119 in Pikeville, turn east on US 119 and travel 22.5 miles to the intersection with KY 319. Turn right on KY 319 and travel 6.0 miles to the project area. The project site is located on the left side of KY 319.

Waste Area Directions: LATITUDE: 37.5603° N, LONGITDE: 82.2324° W. From the project area, travel southeast on KY 319 for 0.9 mile to KY 1056. Turn right on KY 1056 and travel 5.4 miles to the waste area. Turn left on an existing gravel road and the waste area is on the immediate left.

Basic Project Description: The project site is characterized by a small slide, 4 open portals, and seepage from the portals and slide. The slide damaged an existing storage building on the property, which was subsequently replaced following clean-up of the slide by the property owner.

However, there remains a significant amount of seepage from the open portals and throughout the material on the upper bench and below at the elevation of the property owner’s residence.

A 12 foot tall, 75 foot long reinforced concrete wall (AML Standard 30-60-1) will be constructed immediately behind the existing storage building (northwestern side of the project area). From the corner of that wall, a 10 foot tall, 40 foot long reinforced concrete wall will be constructed (northeastern side of the project area). Backfill will be placed behind the walls on a 2:1 slope unless deviation is approved by the Engineer. Subdrains will be placed both in front of and behind the walls. The 4 open portals will be closed with wildlife accessible closures (AML Standard 40-20-1), and a combination rock ditch-drain

(AML Standard 22-30-4) will be placed on both the upper and lower benches to divert water to an existing roadway ditch along KY 319.

It is anticipated that trees in excess of 3 inches diameter at breast height will require removal within the project area. All trees removed as part of the project must be relocated to the waste area for burning unless a suitable area is identified and approved at the project site.

Residential seeding is included to revegetate disturbed areas on the property. Other revegetation bid items are included to revegetate the waste area.

Access to the project site and waste area is via state roads and residential driveways. Repairs to the driveways are included in the bid items.

Construction disturbances will be kept to a minimum with a stringently formulated sediment and erosion control program. Prior to beginning any major earth disturbance, all silt control measures will be installed. This includes silt barriers (bales & silt fence) at the project site and the waste area.

COR & BID & BMP 2

B. ALLOWABLE PRICE LIMIT

The lowest Allowable Price Limit (APL) is listed on the Bid Schedule as part of the bid documents. Unit

Price, Plan Quantity, and Lump Sum are all methods of payment. Significantly low or high values entered by the CONTRACTOR on the Bid Schedule may be considered an unbalanced bid and may have to be justified in writing if such bid is deemed the low responsive bid.

An example would be if a CONTRACTOR assumes there may not be a need for the entire design quantity for Roadway Stone and entered a $10 value for Roadway Stone when the cost at the quarry is significantly higher. Another example would be if the CONTRACTOR enters a value of $30 per linear foot for “SILT BARRIER - BALES & FENCE” to front load payments for work items used near the beginning of the project. The CONTRACTOR is also cautioned that other considerations for rejection may be enforced such as the low bid being higher than the budgeted dollar amount for this project.

C. CONTRACT LENGTH

All work shall be completed within one hundred twenty (120) calendar days from the effective date of the

Award of Contract. Within the bounds of prudent project performance, it shall be the responsibility of the

CONTRACTOR to plan and implement construction sequences which follow the intent of these

CONTRACT DOCUMENTS, particularly as, reflected in the Drawings and Special Conditions and to protect any portion of the contract which may be completed before others.

D. CONTRACTOR’S INFORMATION SHEET

The AML CONTRACTOR/SUBCONTRACTOR INFORMATION FORM sheet must be filled out and submitted with the bid. Failure to submit the AML Contractor/Subcontractor Information Form sheet with the bid will be the basis for declaring the bid “Non-Responsive.”

E. SPECIAL CONDITIONS & PROJECT NOTES

- When applicable, AML is responsible for payment to the Imperiled Bat Conservation Fund

(ICBF). The CONTRACTOR will be responsible for adhering to the boundary for which payment was made and confirming with AML the acreage of trees removed.

- On occasion, a property owner may require a CONTRACTOR to add them on their General

Liability and/or Automobile Insurance as an “Additional Insured.” AML will inform the

CONTRACTOR when this requirement is being made by the property owner. In these cases, the

CONTRACTOR must submit to AML copies of their certificate of insurance documenting the

“Additional Insured” before they will be allowed to mobilize equipment and forces on to said properties. Any fees, rate increases, or other costs incurred by the CONTRACTOR for this requirement, if any, will be considered incidental to mobilization and as such no compensation will be made by AML. The “Additional Insured” must remain on the CONTRACTOR’s policy(s) for the full length of the contract.

F. DAVIS BACON SCALE WAGES

The CONTRACTOR and all SUBCONTRACTORS are required to pay scale wages as defined in the contract documents. If all employment categories that may be used have not been listed and specified in

COR & BID & BMP 3

the contract document, then the contractor must make his best determination of what the missing wage rate will be. Subsequently after the bid is awarded, the contractor must request the specific rate from the

Department of Labor. AML will not issue change orders for additional compensation if the wage rate determined by DOL is higher than the rate the contractor used to develop his bid. If wage rates are not included for a specific category, AML suggests that the contractor assume the highest operator or laborer wages that are listed when developing his bid.

G. PERMITS & FEES – AML will be responsible for obtaining any permits that are checked below.

(Check all that apply)

☒KYTC Encroachment Permit

☒KY DOW Water Permits

☒USACE Permit

The CONTRACTOR is responsible for all other permits and/or fees necessary to begin the project. The

CONTRACTOR is advised that on occasion, other permits and/or fees may be required by federal, state, and local government(s). Other types of permits and/or fees are not the responsibility of AML and as such, these will be the complete and total responsibility of the CONTRACTOR to obtain. These must be obtained before AML will allow mobilization of equipment and forces on to said properties. All costs associated with other permits or fees will be the responsibility of the CONTRACTOR. Please refer to

“General Provisions” in the AML Technical Specifications.

Erosion and Sediment Control

Best Management Practices (BMP) Plan

January 2017

COR & BID & BMP 19

OVERVIEW

This Best Management Practices (BMP) plan is a guide for Kentucky Division of Abandoned Mine Lands

(DAML) projects. It contains information regarding preventing, reducing and controlling erosion, sediment, and pollutant runoff from Abandoned Mine Land (AML) Reclamation and Acid Mine Drainage

(AMD) Abatement project construction sites. The information in this BMP will aid DAML staff and contractors in selecting, installing, and maintaining erosion prevention and sediment control measures during the different stages of construction. This BMP plan, in accordance with DAML Technical

Specifications and Standard Drawings, is intended to protect Kentucky’s streams from potential water quality impacts resulting from DAML projects.

This general BMP document is to outline the various pollution prevention measures used on AML

Reclamation or AMD Abatement Projects. The primary sources of pollutants are solids mobilized during storm events and precipitants from mineralized mine drainage. Other sources of pollutants include oil/fuel/grease from servicing and operating construction equipment, concrete washout water, sanitary wastes, and trash/debris.

EROSION PREVENTION AND SEDIMENT CONTROL MEASURES

Plans for Reclamation and AMD abatement construction projects will include erosion control measures on the planview sheets when possible, and will depict Disturbed Drainage Areas (DDAs) and related information. The construction notes and project description may describe other control measures. The

Contractor and Engineer may select an additional BMP for the project as the project changes and construction progresses. Projects that do not have DDAs annotated in the plans will employ the same concepts selecting and implementing this general BMP plan.

Address disturbed areas or sources of sediments by the most effective means in the specific work area.

Direct non-storm water discharges to sediment basins/traps or to a filter fence enclosure in a flat vegetated infiltration area or filtered via another approved commercial product. All deep mine and surface impoundment water will be tested and treated, when as necessary, to meet the DAML Water-Treatment and Disposal Technical Specification unless stricter limitations are listed in an existing Total Daily

Maximum Load (TMDL) limit.

PERMITS

The DAML shall review each project during project development to determine whether any permits are required to implement the project work. When a permit is required, DAML will make every effort to obtain the permit prior to letting the project for bidding. Permit specific conditions shall trump any standard conditions and/or practices. All permits must be maintained onsite and produced when requested by regulatory authorizes inducing representative of the permitting authority.

Common permits types for DAML projects:

• 401 Water Quality Certification (WQC) o Issued by the KY Division of Water

• 402 KY Pollution Discharge Elimination System (KPDES) o DAML activities are covered under the AML KPDES General Permit

• 404 US Army Corps of Engineers (USACE) o Issued by the US Army Corps of Engineers- Nashville District, Louisville District, or

Huntington District (Depending upon major drainage basin)

COR & BID & BMP 20

• KY Stream Construction (Floodplain) o Issued by the KY Division of Water

• Local Floodplain Permit o Issued by the County/Municipality

• Local Storm Water Construction o Issued by the County/Municipality

A) Field Review Walk-Thru:

The DAML will conduct a project review between the Project Engineer, Construction Branch Personnel, Project Design Technician, and Field Office Staff, to review the construction plans and identify any changes needed prior to letting the project for bidding. The group will evaluate the locations and types of site specific BMP and any other erosion prevention and sediment control measures chosen for incorporation into the final design plans.

B) Site Visit Meeting

DAML will present the project specific BMP and permit requirements/conditions to the potential contractors during the site visit meeting.

C) Pre-Construction Conference

Prior to the actual beginning of the project, DAML will hold a pre-construction conference between representatives of the DAML, the Contractor, including any Subcontractors, as well as other interested agencies and parties. Items discussed will include the time and sequence for construction, planned methods of operation, payment, and other relevant questions including any permit requirements and the erosion and sediment control plan.

D) Construction Access

This is the first land-disturbing activity. Construction entrances shall be a minimum of twenty (20) feet wide by fifty (50) feet long, measured from the shoulder of the public road, and consist of No. 2 aggregate over a heavy weight non-woven filter fabric base. As soon as construction begins, stabilize bare areas with gravel and temporary mulch and/or vegetation.

E) Clearing and Grubbing

Use the following techniques for clearing and grubbing activities:

1) Leave areas undisturbed when possible.

2) Construct silt basins to provide silt volume for large areas.

3) Construct Silt Trap(s) Type A for small areas.

4) Construct Type B silt traps for areas with rapid runoff and sediment-laden runoff.

5) All silt traps should have a 3:1 flow length to width ratio. Add spreader bars, baffles, or turbidity curtains to maintain the flow path ratio when site conditions require traps sizes smaller than the standard detail dimensions.

6) Install geotextile bags and/or rock checks in front of existing drop inlets.

7) Construct diversion ditches to catch sheet runoff and carry it to basins or traps or to divert it around areas to be disturbed.

8) Maintain brush and/or other barriers to slow and/or divert runoff.

COR & BID & BMP 21

9) Construct silt fences/hay bales to catch sheet runoff on short slopes. For longer slopes, multiple rows of silt fence/hay bales may be considered.

10) Apply temporarily mulch to area not actively being disturbed or for any area left undisturbed for fourteen (14) days.

11) Employ non-standard or innovative methods.

F) Stream Crossings / Work Along Streams

1) Temporary low-water stream crossings follow the guidelines included in the DAML Technical

Specifications and those established by the KY Division of Water Floodplain Management

Section. Removal of a temporary crossing may be required to accommodate large storm events.

2) Do not completely block stream flow (even temporary). Instead, utilize some form of pass thru mechanism during all AML projects.

3) Work within a stream channel shall not cause flooding of properties upstream, downstream or within the project area or cause downstream water quality degradation. Minimize equipment contact time with the stream water by diverting water around equipment working in or along streams.

4) No flowing water will interact with any uncured concrete placed in the stream channel.

5) Divert all stream water around the work…
