MARTIN COUNTY, KENTUCKY

Written Location Directions: GPS Location 37° 55’ 0.77”N, 82° 32’ 42.72”W. From the intersection of

US-23 and KY-3 near Prestonsburg: Travel East on KY-3 (Bays Branch Road) 2.6 miles and turn right onto KY-3N. Travel 16 miles and take the ramp (on right) to the intersection with KY-645W. Travel 4.2 miles and turn right onto KY-3411 (Fitch Branch Road). Travel 0.5 miles and turn left onto KY-3 at the intersection. Travel KY-3N 2.1 miles and turn right onto Big Lick Branch Road. Project site is on

Spence Mountain Road (First road on left on Big Lick Branch Road).

Basic Project Description: The Hubert Spence residence is being impacted by drainage from an eligible mine immediately upslope. The Cubert Spence residence is immediately downslope of the Hubert Spence residence with a gabion wall between the residence and Big Lick Branch Road. This wall was recently addressed as part of the Cubert Spence Soil Nails project and this project will remediate issues left after completion of the previous soil nail project. Neighboring residences with drainage addressed under the

Stepp-Webb AML Reclamation Project will require gradework to address settling issues after that project’s completion.

At the Hubert Spence residence, subdrain will be installed between the residence and eligible mine works, 2 portals will be closed with non-wildlife aceessible portal closures and Class II surface ditch will collect drainage. Collected drainage will be routed to the existing installed drains to the north and south of the residence.

At the Cubert Spence residence, a gabion wall will be constructed to support the citizen’s driveway.

Drains installed in the existing gabion wall prior to shotcrete placement will be cut/shortened to prevent issues with passing traffic. The ditch between Big Lick Branch road and the gabion wall will be reconstructed with a 2’ Concrete Swale ditch. Grout that erupted to the surface during soil nail installation will be removed and the yard graded, topsoil placed and revegetated. Shotcrete application resulted in overspray on the metal outbuilding, which will be removed by cleaning or replacement.

Existing gabions at road level previously damaged by an auto accident will be repaired. The top of the gabions subject to shotcrete application will have excess reinforcing steel removed and receive a concrete top treatment. The residential gas line exposed and damaged from the soil nail installation running from the meter at the south end of the gabion walls to the Curtis Spence residence will be replaced and installed under the concrete swale ditch.

At the former Stepp-Webb project properties, the respective yards will be regraded and revegetated after settling around drainage installed as part of the original project and remediation of effects from storage/staging of equipment during the Cubert Spence Soil Nails project. 4” of topsoil for regrading yard areas has been included at the Stepp residence.

Waste generated by construction activities will be transported to an approved waste area approximately

0.2 miles from the project site. The project and waste sites have previously been disturbed by coal mining operations and residential development. Construction disturbances will be kept to a minimum utilizing the approved Best Management practices prior to beginning any major earth disturbance (excluding initial site preparation for access only) until all silt control measures will be installed. These include but are not limited to silt barriers (bales & silt fence). No trees greater than 3” diameter at breast height will need to be cut or removed for completion of the project. All disturbed areas (including waste areas) will be promptly revegetated at the end of construction. Cover crop is also provided in order to provide quick vegetative cover on any disturbed areas that will go undisturbed for at least two weeks, but not be ready for application of permanent revegetation. This project will affect Big Lick Branch stream as waste material will be placed in the floodplain. A valid Stream Construction Permit has been secured.

Erosion and Sediment Control

Best Management Practices (BMP) Plan

January 2017

COR & BID & BMP 23

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…
