Permit Modification

1.0 INTRODUCTION
Vulcan Construction Materials, LLC ("Vulcan") operates the Rockingham Quarry, Permit No.
77-01, in Richmond County, North Carolina. The site is located on the south side of NC
Highway 1117, Galestown Road,where it intersects US 74.
This mining permit modification provides an overview of the existing conditions of the quarry
and a detailed plan for the proposed site improvements. The proposed activities are to be within
existing permitted mine boundary and utilizes the northeast side of the existing quarry property
to expand the second quarry excavation pit to remove granite rock.
1.1 EXISTING CONDITIONS
Property and Permit Boundary
The existing permitted property at Rockingham Quarry consists of 1,461.22 acres of land owned
by Vulcan Lands, Inc. This permitted area is shown on Drawing C 100 - Operations Plan in
Appendix A.
Landuse
Within the 1,461.22-acre permitted area, Vulcan currently has approximately 645.1 acres for
quarry related activities including: approximately 61.0 acre for tailings/settling pond area, 158.0
acres for overburden (dirt) storage area, 118.3 acres for stockpiling, 77.6 acres for processing /
haul roads area, and 230.2 acres for mine excavation area. The remaining areas are used for
stream redirection and other site improvements.
Wetlands and Streams
The area included in this permit modification request has been investigated for the presence of
Waters of the U.S. (wetlands and streams). Any such areas have been verified and delineated
using appropriate protocol and their locations surveyed. Phase 3 of the proposed modification
area will impact Waters of the US. Vulcan has an application with United States Army Corps of
Engineers for an individual Section 404 Permit (IP) for permanent impacts on jurisdictional
Waters of the US and is currently under review.

1.2 PROPOSED MODIFICATIONS
All the property involved in this mine permit modification is within the existing approved mine
permit boundary. There are no new lands being added to this permit. This modification would
change the total affected/bonded acreage to approximately 803.3 acres = (existing permitted of
697.3 plus the proposed disturbance of 106.0). All land associated with the mine permit
modification is owned by Vulcan Lands, Inc. (a wholly owned subsidiary of Vulcan Materials
Company).
The permit modifications consist of these parts:
1. Removal of two existing regulated stream sources.
2. Diversion of existing stream away from project activities.
3. Installation of temporary erosion control measures to support future mining activities.
4. Installation of access roads around the perimeter of proposed mining limits.
5. Installation of erosion and sedimentation control measures to support extension of the
north overburden stockpile.
6. Extension of overburden stockpile haul road and sediment channels.
7. Mining activities within Phase 3 mining limits.
8. Placement of overburden material in the extension of the north overburden stockpile area.
1.3 PHASE 3 WATER MANAGEMENT
Phase 3 will manage stormwater runoff in two major areas of the project site: the mining pit and
the overburden stockpile extension areas.
In the mining pit, the project will begin at the south mining pit adjacent to proposed activities by
clearing areas where excavation is expected. Grading is designed to direct stormwater runoff to
the existing mining pit as excavation progresses. The site will collect stormwater runoff at
location points within the existing mining pit as dictated by site operations. Clean water will be
pumped to approved discharge points monitored by Vulcan in a manner recommended by
NCDEQ Department of Water Resources.

A 150-ft wide working area will be graded to allow mining equipment to access the areas to be
excavated. The working area will be sloped towards a collection channel to the east to
concentrate the runoff away from the working face. The collection channel is sloped to drain to
the existing south mining pit. The working area will extend 1,750 feet north into Phase 3 mining
pit.
The site will plug the existing stream sources at the entrance to their respective receiving water
bodies by using class B riprap. This will stabilize the existing ground while providing filtration
means for any groundwater or surface water runoff that may occur during excavation activities.
The site will also divert an existing stream on the northwest. After plugging the existing stream
source within Phase 3 mining pit with class B riprap, the remaining water body will be regraded
to divert flow away from the project site.
Construction of a perimeter road as detailed in the proposed plans will enclose Phase 3 mining
pit after which, mining activities can begin. The contractor will ensure that stormwater will be
diverted into the working area and into the existing mining pit to the south throughout the life of
this project.
In the overburden stockpile extension area, a 6" perforated underdrain pipe will be installed at
the natural low draining path. The underdrain pipe will collect seepage that may occur during
and after fill placement. Seepage will be directed thru the pipe to a discharge point outside the
stockpile area grading. Erosion and sedimentation control measures will also be installed: silt
fence, silt fence outlet, diversion ditches, and sediment channel with rock check dams and
spillway. As the overburden pile is raised, side slopes will be graded with benches sloped to
drain inward and down to collection points. HDPE slope drains will be installed at these
collection points and run perpendicular downslope to drain into the sediment channels. The
owner may opt to use riprapped downchute in place of the HDPE slope drains depending on
availability of rock riprap at time of construction.

1.4 CONSTRUCTION SEQUENCE FOR PHASE 3
1.4.1 Construction of Phase 3 Mining Pit
Step 1 Initial Construction Sequence
1. Flag work limit and mark buffer areas.
2. Vulcan to coordinate pre-construction meeting with including but not limited to the
following parties: engineer, town or county representative, NCDEQ inspector, and
general contractor.
3. Begin grading work area from existing mining pit. Provide a working width of 150
feet, sloped 2% away from perimeter road. Provide a drainage ditch to collect
stormwater from the working area.
4. Install perimeter road up to limits shown on the plan. See perimeter road section
detail on sheet C802.
5. Stabilize slopes with permanent seeding.
6. Continue mining activities to Step 1 limits.
Step 2 Construction Sequence
1. Install rock berm filter at stream outlet at step 2 limits.
2. Only cut the diversion channel along the east side to intercept the existing channel flow.
Initial work in this step shall not include any fil..
3. Clear vegetation within limits as shown on the plan.
