About this file
This is a construction plan document prepared by the West Virginia Department of Environmental Protection, Office of Abandoned Mine Lands and Reclamation, for remediation work at the Valley Camp Mine Facilities located in Ohio County, West Virginia, near the Wheeling quadrangle along US Route 40. The project involves demolition and remediation of abandoned mine infrastructure including an existing concrete silo (35-foot outside diameter, 142.6-foot height), pump station with concrete shaft, and various rubble and waste areas across a 4.22-acre site. Primary work tasks include removal of metal structures and concrete foundations to one foot below existing grade, construction of a concrete waste area with specific capping procedures (6-inch AASHTO #1 layer followed by 6-inch 1.5-inch crusher run cap), stabilization and filling of the pump station void with riprap and soil, gravel drive rehabilitation along multiple access routes, and final site grading to approximate original contours with seeding and mulching. The plans specify stabilized construction entrance installation, silt fence placement, rain gauge and NPDES sign locations, and equipment/storage staging areas.
Access to the site presents two options: use of an existing bridge owned by Ohio County Commission (requiring a usage agreement and contractor evaluation by a registered professional engineer, with a required $1,500,000 performance bond for potential bridge replacement costs), or an alternate temporary stream crossing and access road that the contractor must design, permit, and install, then remove upon project completion. All demolished concrete must be crushed to sizes less than 24 inches with reinforcement removed to an approved off-site disposal facility. Asphalt areas damaged during construction require repair with 2-inch hot mix asphalt wearing course as directed by the engineer. Gravel drive rehabilitation requires base grading into crowned or sloped configurations with separation fabric and compacted crusher run stone placement. The contractor bears responsibility for locating all existing utility and stormwater facilities, verifying facility conditions during construction, and ensuring all runoff is directed to best management practices throughout the project duration.

SILT FENCE INSTALLATION INSTRUCTIONS:
STEP 1: EXCAVATE TRENCH A MAXIMUM OF 4-INCHES WIDE AND 8-INCHES DEEP. THE TRENCH SHALL BE HAND-CLEANED FOLLOWING EXCAVATION TO REMOVE BULKY DEBRIS SUCH AS ROCKS, STICKS, AND SOIL CLODS.
STEP 2: PREPARE AND LAY SMARTFENCE 42 OUT ON THE GROUND ALONG THE PROPOSED FENCE LINE AND NEXT TO THE ANCHOR TRENCH. DURING THIS STEP, ANY DAMAGED SILT FENCE WILL REQUIRE
REPLACEMENT.
STEP 3: INSTALL INITIAL POST BY PLACING THE END OF SMARTFENCE 42 ALONG THE POST HEIGHT AND ROTATE THE POST 360 DEGREES, MAINTAINING TENSION ON THE FABRIC. SECURE THE FENCE TO THE POST AT ALL FOUR (4) ORANGE-COLORED BAND LOCATIONS WITH STEEL WIRE OR NYLON TIES AS PER NOTE 1. DRIVE THE INITIAL POST (72” METAL T-POST) WITH THE ATTACHED FENCE TO A DEPTH OF 36” BELOW
SURFACE.
STEP 4: INSTALL INTERIOR POSTS USING SPACING NO GREATER THAN 72-INCHES ON CENTER, DRIVE INTERIOR POSTS TO A 36-INCH DEPTH BELOW SURFACE AND ATTACH THE FENCING AS PER NOTE 1 BELOW.
TO ATTACH FENCING, POSITION SMARTFENCE 42 IN FRONT OF THE ADJACENT T-POST, PULLING THE FENCING TIGHT AND FASTEN IT TO THE POST AT ALL FOUR (4) ORANGE-COLORED BAND LOCATIONS AS PER NOTE 1 BELOW. IT IS CRITICAL THAT SMARTFENCE 42 IS PULLED TIGHT PRIOR TO ATTACHING IT TO EACH INTERIOR POST.
STEP 5: INSTALL FINAL POST, AFTER THE INTERIOR POSTS HAVE BEEN FASTENED, SECURE THE FENCE TO THE FINAL POST BY PULLING THE FINAL SECTION OF FENCING TAUT, AND THEN ROTATING THE POST 360 DEGREES WHILE MAINTAINING TENSION ON THE FENCE SYSTEM. SECURE THE FENCE TO THE POST AT ALL FOUR (4) ORANGE-COLORED BAND LOCATIONS WITH THE STEEL WIRE OR NYLON TIES AS PER NOTE 1 BELOW. DRIVE THE FINAL POST INTO THE GROUND TO A 36-INCH DEPTH BELOW THE SURFACE.
STEP 6: BACKFILL TRENCH ENSURING THAT THE BOTTOM 8-INCHES OF FABRIC HAS BEEN PLACED IN TRENCH. BACKFILL TRENCH (OVERFILL) WITH SOIL PLACED AROUND FABRIC. COMPACT SOIL BACKFILL MANUALLY OR VIA MECHANICAL EQUIPMENT SUCH AS THE FRONT WHEEL OF A TRACTOR, SKID STEER, ROLLER, OR OTHER DEVICE.
NOTE 1: FASTENING SMARTFENCE 42 TO T-POSTS, USE ONE OF FOLLOWING METHODS:
STEEL WIRE: WIRE-ATTACH SMARTFENCE 42 TO METAL T-POSTS USING 16-GAGE 304 SS WIRE WITH MITERED ENDS, SECURING WITH SAFETY PLIERS.
NYLON TIES: PUNCTURE TWO 0.25” OPENINGS, SPACED AT A WIDTH APART THAT IS ROUGHLY EQUIVALENT TO THE POST WIDTH, AND SECURE THE FENCE TO THE POST USING 8” NYLON HEAVY-DUTY CABLE
(ZIP-TIES) THAT ARE UV RESISTANT AND HAVE A MINIMUM 120-LB TENSILE STRENGTH.
MAINTENANCE:
· CONTRACTOR SHALL CLEAN OUT SEDIMENT BEHIND THE SMARTFENCE 42 ONCE THE SEDIMENT REACHES A HEIGHT OF 50% OF THE SILT FENCE. THE SEDIMENT SHALL BE INCORPORATED INTO THE FILL WITHIN THE
DISTURBED AREA.
