23117AMLBAML RECLAMATION PROJECT

PIKE COUNTY, KENTUCKY

The address is 1664 Frozen Creek, Racoon, KY 41557, the coordinates are 37.4842, -82.4500. Project limits include 8.6 acres, with an expected disturbance of 4 acres within project boundaries. Project limits for the offsite waste area includes 2.2 acres, with an expected disturbance of 1 acre.

There is a significant amount of water that is draining from the mine bench causing problems (small slides, mold, drainage, etc.) the proposed plans is to control the water and get it into Frozen creek which is across the road. Access to the bench will be via the gravel driveway down the road from the residence, used to access another residence at the bench level. At this residence, there is drainage from behind the driveway from an old closed portal which is saturating the area and flowing along the driveway. Water has also caused a small slip on the hill adjacent to the drive. This material will be removed and a rock toe buttress installed to stabilize the hill above the road. Approximately 600LF of ditchline will be installed along this drive and up to the portal. Drainage controls will be installed on the bench and at the house level. A small block wall will be installed behind one home to stabilize a small slide and handle drainage.

A. STANDARD DOCUMENTS

The AML Standard Details and Technical Specifications are posted on the Division’s website at https://eec.ky.gov/aml

Once on the web page, please click “Contractor Information” tab located on the right side. AML standard technical specification and detail are located under this tab. Contractors are strongly encouraged to review the complete AML website for additional information.

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 eighty (180) 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.

COR & BID & BMP 2

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

(IBCF). 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 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

Erosion and Sediment Control

Best Management Practices (BMP) Plan

COR & BID & BMP 24

January 2017

COR & BID & BMP 25

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…
