PERRY COUNTY, KENTUCKY
Written Location Directions: From the Hazard AML office, turn left onto KY-15 N, then turn left onto
KY-15 N/Johnny Cox All-American Drive. Stay on for 7.6 miles, then take a left onto Harvey Lane. The slide and project area will be on the right in approximately 0.1 miles.
To reach the waste area from the project area, return to KY-15 and turn right. Stay on for 2.9 miles, then turn left onto KY-267. In 0.9 miles, make a sharp left turn; the waste area will be at the end of the access road.
Basic Project Description: The slide area along Harvey Lane will be stripped to rock and taken to the waste area. Rail steel with guardrail lagging will be installed to protect buildings above the slide, and pilot holes will be used to determine necessary rail steel length. A subdrain will be constructed on the bench above the slide to redirect water away from the slope. Several new 18” HDPE pipes will be installed to control drainage coming down the hill and in front of the slide. A concrete ditch will be constructed to carry drainage and to protect the road. A new 24” HDPE pipe will be installed under
Harvey Lane to carry drainage to a larger watershed. Other items such as bituminous repair, silt control fence, revegetation, and others are included to address construction activities.
A. STANDARD DOCUMENTS
The AML Standard Details, Technical Specifications, and Bid Item Descriptions 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
(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.
- A modified concrete ditch will be used for a portion of this project. An adjusted detail is included as part of the planset documents.
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

Erosion and Sediment Control
Best Management Practices (BMP) Plan
January 2017
COR & BID & BMP 21
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:
COR & BID & BMP 22
• 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)
• 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:
COR & BID & BMP 23
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.
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 areas in accordance to methods listed in the DAML
Stream Protection & Relocation technical specification, AML Standard Details Section 60, and as by the appropriate permit guidelines.
6) Temporary out of channel stream diversion must use one of the three approved methods:
pipe diversion, sandbag/stone channel diversion, and/or fabric-based channel diversion.
Do not construct any temporarily diverted channel on bare, erodible soil. No temporary diversion shall be permanent without a 401, 404, and other appropriate permits.
COR & BID & BMP 24
G) Deep Mine and Surface Water Impoundments
The DAML Resident Inspector will test the mine water from deep mines and surface impoundments on the project area to determine the pH and total iron content. Treat the water until it meets the DAML Water-Treatment and Disposal Technical Specification or an existing TMDL, whichever is stricter, before release through a silt control structure(s).
