Westmoreland Partners operates a coal-fired power generating facility in Weldon, North
Carolina. The Coal Combustion By -Products (CCB) was approved for beneficial use in
refilling 7-acre (+/-) soil borrow site situated 4.4 miles south of Weldon at 4752 Highway
301 in Halifax County. The soil borrow site is licensed as a mining facility by the
property owner, O.N. (Nat) Vaughan. Mr. Vaughan and Westmoreland Partners have an
agreement whereby Westmoreland will provide CCB as a structural fill to restore the
borrow site as provided for in Section .1700 of the North Carolina Solid Waste
Management 15A NCAC 13B Rules.
This report describes the structural fill placement, erosion control measures and the
closure design and provides drawings and photographs documenting that this structural
fill site meets the requirements prescribed in Section .1700 of the North Carolina Solid
Waste Management 15A NCAC 13B Rules, for Beneficial Use of CCB's.

The structural fill material is a CCB that was used to restore a former borrow site. The
structural fill was transported from the Roanoke Valley Power Plant (ROVA) to Mr.
Vaughan's borrow site from February 2008 to April 2009. The material was transported,
placed and compacted, and sloped according to Section .1700 of the North Carolina Solid
Waste Management 15A NCAC 13B Rules. The following sections outline how the
structural fill construction conformed with Section .1700 Rules.
2.1 Transportation
Fly ash from the power plant is collected in silos. The ash is moistened as it is
discharged from the silos into open -topped trucks. This quenching increases the water
content of the structural fill material to prevent dust generation. Covered trucks were
used to haul the structural fill material as another measure to prevent dusting from
occurring during transportation.
2.2 Placement/Compaction
The structural fill was unloaded from the trucks in a controlled manner to prevent dust
from becoming airborne. After the material was unloaded it was spread in approximately
24" thick lifts and compacted. URS personnel performed several standard Proctor tests
(ASTM D 698), and the field density and moisture content tests (ASTM D 2937 & D
2216, respectively) on site. The test results indicated that the structural fill material was
adequately compacted. A summary of the Proctor tests and the field moisture/density test
results for the structural fill is presented in Appendix B and C, respectively.
2.3 Stability
The structural fill material was placed and graded so that side slopes were less than 4
horizontal : 1 vertical slope. To maintain stability of perimeter slopes and control erosion
due to runoff from the final cover.

O.N. Vaughan Structural Fill Site ROVA —Weldon, NC
Erosion control features were installed and maintained as prescribed in the approved
Erosion and Sedimentation Control Plan. The plan was approved by NCDENR on
December 13, 2007. Several erosion control features that were installed and maintained
throughout this project are discussed below.
3.1 Drainage Features
A stilling basin was constructed, prior to placement of the fill, in the northwest corner of
the borrow area, see photo 1 in Appendix A. Discharge from the stilling basin is filtered
through two stone check dams, see photo 2 in Appendix A. The base of the borrow site
slopes at approximately 1 % from the southeast corner to the stilling basin in the
northwest corner. An earthen containment berm was constructed between the stilling
basin and the floor of the borrow area to prevent fill material from entering the stilling
basin.
A perimeter stormwater control ditch was constructed along the borrow site limits to
divert stormwater away from the borrow area. The slope of the ditch varied from 2.6% to
1%. To reduce amount of soil being tracked onto Highway 301 the final 50-feet of gravel
access road was surfaced with coarse aggregate (2" to 3" nominal size). These features
and the earthen sediment trap near the active fill areas provided sufficient erosion control
to limit sedimentation from migrating off site.
3.2 Maintenance
The erosion control features were checked periodically throughout this project and
especially during and after a major storm event. At times additional rock was added to
the check dams and built-up sediment was removed from the channel and dams. During
a storm event the drainage channels were checked to see if any water bearing sediment
migrated off site. There was no visual evidence of the fill material migrating off site.

O.N. Vaughan Structural Fill Site ROVA —Weldon, NC
The last time the structural fill material was accepted was on April 9, 2009. From April
to May cover material was placed over the structural fill. The cover material was
specified and placed according to Section .1705 of the North Carolina Solid Waste
Management 15A NCAC 13B Rules. During the month of June the site was seeded to
minimize erosion of the cover material.
4.1 Cover Material
After the structural fill material reached final grades the area was covered with soil
according to Section .1705 0) of the North Carolina Solid Waste Management 15A
NCAC 13B Rules. Twelve inches of cover soil, plus six inches of topsoil capable of
supporting vegetation, was used to cap the structural fill material. Final cover placement
was started within 30 working after the filling process has ceased.
While the cover material was being placed URS regularly probed the soil cover on a grid
pattern to measure the cover material thickness. Cover soil thickness were field marked
using flags. Not all areas where cover thickness were less than 18 inches in thickness
were rechecked. The flags used as grade stakes were used by the contractor to control
cover thickness. A map was created documenting URS's cover material thickness
measurements (see Appendix D). After URS verified that the site was adequately cover
with 18 inches of covered soil the Owner began liming, fertilizing and seeding. The site
was seeded on June 23-25.
4.2 Configuration
According to Section .1706 of the North Carolina Solid Waste Management 15A NCAC
13B Rules the final surface of the structural fill shall be graded to:
• Minimize erosion of cover material,
• Promote drainage of area precipitation and minimize infiltration,
• Prevent ponding of surface water.
The side slope was graded to a less than 4H:1 V slope and the top of the fill material was
graded at a 5% slope. These slopes comply with Section .1706 of the Rules intended to
prevent ponding and infiltration, but at the same time being gentle enough to prevent
erosion.
4.3 Recordation
Section .1707 of the North Carolina Solid Waste Management 15A NCAC 13B Rules
requires the land owner to submit a notarized statement describing the volume and
location of coal combustion product to the county Register of Deeds within 90 days after
completion of the project. On May 11, 2009 the Owner recorded the deed change with
Halifax county.
