I. SPECIAL PROVISIONS

I.

LOCATION / SITE DESCRIPTION

The project consists of an old mine bench with drainage issues and two open portals (Portals P1 and P2). The old bench currently exhibits standing water due to mine drainage. Portal P1 drains into a natural drainage feature which flows by Stevens Chapel Church in a channel to Hewitt Creek. The project will include: mine dewatering/treatment, installation of one modified wet seal, installation of one double 36 inch diameter bat gate mine seal, and grading to establish proper drainage on the old mine bench in order to eliminate standing water. Other work will include; temporary erosion and sediment control, temporary improvement of existing roads for construction access, and re-vegetation of disturbed areas at completion.

Directions to the Site:

Travel South on US 119 (Corridor G) from Charleston.

Exit left on Garrett Fork Road (CR 7).

Travel 7.2 miles on Garrett Fork Road to Stevens Chappell in Lake WV.

Site is on the hillside to the southwest of the chapel.

To access the site continue on CR 7 another 0.4 miles to a blue bridge on the right.

Cross Hewitt Creek and travel on an unimproved road to the site.

Site Coordinates: N37º 55’ 54” W81º 53’ 32”

Basement floors shall be shattered. Pits, trenches, holes, or basements shall be backfilled. Any buried mining debris and ruins encountered during excavation shall be removed as directed by the WVDEP. Abandoned mining equipment and all metal encountered shall be removed from the site to an off-site disposal area in accordance with Special Provisions Sections IV and V or to a landfill approved by the WVDEP to accept this type of debris. The WVDEP shall be the sole judge as to what is buried and what is to be removed from the site. Areas where structures and buildings are removed shall be graded to provide positive drainage so surface runoff will not pool or impound as directed by the WVDEP.
