Subject: Martin Marietta Materials, Rocky Point Quarry - Request to amend 401 WQC
Joanne-
Good afternoon. Attached is a request to amend Martin Marietta's 401 WQC for the Rocky Point Quarry to discontinue
hydrologic monitoring eastward of the reclaimed portion of the mine. Monitoring per the Alternative Modified Pumping
Plan will continue for the southern portion of the site as we discussed during our onsite field meeting held on January
29, 2013.
I will send a hard copy of the request, and attached figure as well.
Please contact me should you have any questions or need additional information.
Thanks,
Chad

Re: Request for Modification of 401 Certification
Martin Marietta Materials, Rocky Point Quarry
NC DWQ Project No. 03 -1023
Dear Ms. Steenhuis:
On behalf of our client, Martin Marietta Materials (MMM), Kimley -Horn &
Associates (KHA) is submitting this request for a modification to the existing
401 Water Quality Certification for the Rocky Point Quarry project referenced
above. This requested change to the 401 Certification conditions is made per our
onsite discussion held on January 29, 2013 and MMM's requests to reduce the
monitoring east of the quarry where mining activities have ceased and
reclamation is completed.
The 401 Certification requires the Modified Alternative Pumping Plan to be
implemented throughout the time the facility is actively mining and conducting
measures necessary to reclaim the mine footprint. This includes creating a
hydrologic barrier to subsurface drainage from the eastern parcels (H1,H2 and
the avoided portions of G1); the redirection of a portion (1/3) of the dewatering
discharge currently directed to Strawberry Branch to the drainage way east of the
mine between H 1 and H2. The 401 Certification also required maintaining
hydration to the western portion of Tract G2 throughout the time the facility is
actively mining. Based on our site visit, we agreed that the areas listed above
are no longer being actively mined and should no longer be subject to the
Modified Alternative Pumping Plan. Therefore, MMM proposes to continue
monitoring per the Modified Alternative Pumping Plan south of the active mine
and cease monitoring east of the reclaimed portion of the mine as shown in the

attached figure. In addition, MMM will cease discharge to Strawberry Branch.
The permanent water body within the reclaimed pit will provide a hydrologic
barrier to the eastern properties while mining activities move southward and
further from the eastern tracts.
With these monitoring and discharge changes implemented, MMM can proceed
with coordination with NC Division of Land Resources to have the reclaimed
portion of the mine site released from the mining permit and document that
reclamation has been completed, thereby turning the property back to the
management and control of the property owners.
Please contact me at 919- 677 -2121 should you have any questions or need
additional information.
Very truly yours,
KIMLEY -HORN AND ASSOCIATES, INC.
