24026AMLBAML CONSTRUCTION NOTES

Steel Beam / Rail Steel Orders:

No beams or rail steel shall be ordered for any project until written approval has been given by the ENGINEER. The CONTRACTOR is advised that many projects do not have any subsurface data.

As such quantities listed on the bid schedule, are best estimate based on maps and topography features observed in the field. Even on projects that have subsurface data, quantities listed may still be subject to revision.

Beams (W or HP)

Beams need to be rolled, and typically it takes 4 to 8 weeks before a roll date is issued for a specified beam. AML will work with the CONTRACTOR to allow time to get the beams ordered, rolled, and on-site. During this period, the CONTRACTOR may be granted excused days or may work on different features of the project. AML expects this period as short as 21 calendar days to 75 calendar days maximum. Based on pilot hole information obtained during reclamation activities, AML will determine the lengths of each piece needed in 5-foot increments. A table will be developed by AML and submitted to the CONTRACTOR. AML does not expect any beam to be greater than 50 feet for this project.

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.

Erosion and Sediment Control Best Management Practices (BMP) Plan

January 2017

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

COR & BID & BMP 22

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) 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
