SUBJECT: Martin Marietta Materials, Inc.—Fuquay Quarry
Mining Permit No. 92-12
Response to November 16, 2023 Request for Additional Information
Dear Mr. Parr:
1. An updated detail sheet is enclosed, containing the following requested maintenance details:
a. Sediment Traps and Basins
i. Inspect sediment traps and basins in accordance with NCG020000 requirements.
1. Fix any observed deficiencies in a timely manner
2. Remove any observed trash or debris in a timely manner
ii. Remove sediment,and restore the trap to original dimensions when accumulated
sediment reaches%z of its design depth
iii. Replace any stone impaired by sediment
iv. Dispose of removed sediment, similarly to any pond fines or overburden
b. Ditches
i. Inspect in accordance with NCG020000 requirements
1. Remove any flow obstructions
2. Repair diversion ridge
c. Make timely repairs to outlets as needed
2. The enclosed detail sheet contains an additional detail for the permanent sediment basin
presently located north of the current plant site. Based on aerial imagery, this basin has been
installed for at least 25 years.
3. All proposed disturbed areas have corresponding erosion and sediment control measures. These
disturbed areas are contiguous across the site,and provide access to other types of areas. Internal
transportation routes evolve as site development progresses. All disturbed areas can be accessed
from the entrances shown on the enclosed map. Crossings, which are considered permanent,
have now been called out as such.
4. The enclosed detail sheet includes construction and the following maintenance details for the
proposed construction entrance.
a. Topdress stone with similar stone prior to mud or sediment leaving the site.
b. Immediately remove any material spilled,washed, or tracked onto a public road.
5. As shown on the enclosed mine map, the current entrance will remain. It is now included in the
acreage table.
6. Tutor Stephens Road has a 50' undisturbed buffer on both sides of the road. Thus, the plant will
have a 100' undisturbed buffer that is bisected by the public Fletcher Tutor Road. The proposed

unexcavated buffer will be used to access and maintain erosion and sediment control measures.
The area south of Tutor Stephens Road is addressed in response No. 9.
7. The mine map has been updated to show the 150' undisturbed buffer.
8. Access will be maintained to the cemetery from Tutor Stephens Road. The cemetery is located in
the silvicultural buffer. No disturbance is permitted in this area for mining activity and it remains
outside the future pit area.
9. The area south of Tutor Stephens Road will be used primarily as a laydown yard. We do not
anticipate frequent traffic across the public road.
10. The Kring Property will continue to use Tutor Stephens Road. We lease property from the Krings.
They are aware of our plans and we are coordinating with them to ensure continued access.
Access to our operation will be limited by gating entrances and vegetated (undisturbed) buffers.
11. The 401 number referenced in my September 20, 2023 cover letter matches the number on a
September 1, 2023 letter from Michael Pjetraj, Deputy Director of DWR, to Lyle Phillips, of the US
Army Corps of Engineers. However, the November 27, 2023 401 Water Quality Certification lists
the project number as DWR#20061885v3.
12. The proposed project is in the Cape Fear River Basin, so the Neuse Buffer rules do not apply. All
wetland and stream areas included within nonbuffered areas have been included on the attached
mine map. Any silvicultural activities occurring within the silvicultural buffer will comply with all
local, state, and federal regulations.
If you have any questions please contact me at(919) 783-4505 or via email at
[e-mail]. After January 1, 2024, please reach out to Brian North at (919)
664-1694 or [e-mail].
