Provide a certified Geohydrologic map identifying the following: Identify as
attachment I-8.
NOTE: Proposal map can be utilized only if this additional information does not make the map
difficult to read.
A.
Locations (latitude and longitude) and elevations of all bore holes and
sampling sites;
The locations and elevations of all bore holes and sampling points are shown on the
attached map.
B.
All mineral croplines and the strike and dip of the coal to be mined;
The outcrops of the Waynesburg and Waynesburg A coal seams are shown on the
attached map. Strata at the proposed mine site are nearly horizontal, with a strike of
approximately N. 10-20º E. Regional dip in north-central West Virginia is typically to
the northwest. According to structural contour mapping on the Waynesburg coal
available from the West Virginia Geological Survey, local dip in the vicinity of the
site is approximately 1.1 percent to the west-northwest, and no significant fold axes
are present in the vicinity.
C.
Existing or previous surface mining limits with their permit numbers;
No previous surface mining has been performed in the Waynesburg or Waynesburg
A seams at the subject property. Previous surface mining in the Waynesburg and
Waynesburg A coals has been conducted by Patriot Mining Company at adjacent
sites, including the New Hill (S-2010-01) and New Hill East (S-2010-04) surface mines
to the east; Guston Run North (S-1002-00); Guston Run South (S-2010-06); and
Guston Run South Extension (S-2006-07) surface mines to the north and northeast;
and Scotts Run surface mine (S-1002-97) to the east-southeast. The Guston Run
South and Guston Run South Extension mines are active, and New Hill East surface
mine is inactive. The New Hill, Guston Run North and Scotts Run surface mines are
fully reclaimed.
Deep mining below drainage level has been conducted in the Sewickley and
Pittsburgh coal seams, which lie approximately 300 feet and 400 feet, respectively,
beneath the Waynesburg coal. Workings of the Osage Coal Company Osage Mine
and Consolidation Coal Company Pursglove No. 15 Mine are present beneath the
proposed permit area.
Data collected to assemble the PHC indicate that impacts to the immediate receiving
stream (Scotts Run and unnamed tributaries) from previous surface mining have
been minimal. The streams exhibited pH values generally in excess of 7.50 with low
metal concentrations.

D.
Location and extent of known workings of any underground mines and
auger mined areas, including mine openings to the surface. Label these
openings as to whether they are currently discharging water or are known to
have discharged water in the past;
Four punch mine openings in the Waynesburg coal were observed at the site during a
pre-inspection. One opening located southeast of existing Pond No. 2 exhibited no
discharge. One opening located about 400 feet southwest of NH-13-08 had a pipe
installed as if to promote drainage, although no flow was observed on the date of the
pre-inspection. The third opening is about 400 feet southwest of NH-9-08, and
exhibited no discharge. The final opening is located about 700 feet northwest of NH9-08, and exhibited no discharge. All openings will be mined out during the proposed
mining activity.
Deep mining activities have been conducted beneath the site in the Pittsburgh and
Sewickley coal seams, which are respectively about 400 feet and 300 feet below the
Waynesburg seam in elevation. No discharge is known to have occurred presently or
in the past from deep mine workings on the proposed minesite.
E.
Areal extent of aquifers with the name(s) of the stratum (or strata) in which
the water is found and show the anticipated direction of water movement;
Three hundred eighty two properties within a one-half mile radius of the proposed
operation were inventoried for water use. Ten residences were found to use
groundwater from wells or springs as the sole source of water supply. The remaining
residences obtained water from municipal lines maintained by Morgantown Utility
Board (MUB) or Pleasant Valley PSD. Fourteen residences with city water service
maintain a well, spring, or pond as an alternate water source. Most inventoried wells
and springs are located in valley bottom areas below the elevation of the Waynesburg
coal. These groundwater sources appear to tap the stress-relief fracture aquifer
system along local stream valleys as a source of water.
The presence of groundwater was not noted on the drillers’ logs for any of the
overburden tests. Based on general stratigraphic information for the Monongalia
County area, expected potential aquifers in the area to be mined include the
Waynesburg coal and the overlying Waynesburg sandstone. These units appear to
have been locally developed at W-2 and W-3 which are within the proposed mining
area and will be removed by mining. General groundwater movement in abovedrainage strata is down gradient to outcrop discharge areas. Groundwater flow in
deeper strata is most likely controlled by stratigraphic dip.
A shallow aquifer system is located in nearby valley bottom areas in the vicinity of the
proposed mine. The presence of this aquifer system is believed to be largely related to
the stress-relief fracture system discussed in Section I-9.C more so than local
lithology. All but two of the primary groundwater sources documented during the
inventory are completed in this aquifer system.
Aquifers at greater depth below drainage level may be at least partially dewatered by
deep mining activities in the Sewickley and Pittsburgh coal seams beneath the
proposed mining area. According to structural contour maps available at the West
Virginia Geological Survey, the Sewickley and Pittsburgh coal seams lie
approximately 300 feet and 400 feet, respectively, below the Waynesburg coal.

F.
Location and depth of all oil and gas wells, and their Office of Oil and Gas
permit numbers, for all wells which are within the proposed mining limits
(surface or underground) and/or within 1000 feet of the proposed permit
boundary;
No gas wells are located within the bonded area.
G.
Presence and attitude of any known structural features such as faults; axial
traces of
synclines, anticlines, and monoclines; and any recognized fracture patterns
of lineament traces;
Strata at the proposed minesite are nearly horizontal, with a strike of approximately
N. 10-20º E. Regional dip in north-central West Virginia is typically to the northwest.
According to structural contour mapping on the Waynesburg coal available from the
West Virginia Geological Survey, local dip in the vicinity of the site is approximately
1.1 percent to the west-northwest, and no significant fold axes are present in the
vicinity.
According to WVGS Map WV-7A, no linear features pass through the area to be
mined. Two linear features are located in the vicinity of the proposed minesite. The
locations of these features are as follows: 1) a linear feature approximately 4 miles in
length and follows the Scotts Run valley westward from Pursglove with an
approximate east-west orientation, and passes within 1,000 feet to the south of the
southernmost extent of the proposed permit area; and 2) a linear feature
approximately 6 miles in length with an orientation of about N. 15-20º W. that follows
an unnamed tributary of Scotts Run through New Hill and Cassville, and southward
along Dents Run toward Laurel Point. This feature passes within 1,000 feet of the
west end of the proposed operation.
