With respect to the modification request from Kimley -Horn and Associates, Inc. dated February 26, 2013, it is agreed by copy of this letter that 401 Water Quality Certification # 3452, dated March 15, 2004 and modified on May 14, 2004 and May 25, 2004, is modified to reduce the monitoring east of the quarry where mining activities have ceased and reclamation is completed (see attached aerial). This also includes ceasing the discharge to Strawberry Branch. Martin Marietta Rocky Point Quarry is required to continue the monitoring per the Modified Alternative Pumping Plan south of the active mine. All other certification and conditions remain unchanged and are in effect.

February 26, 2013 Ms. Joanne Steenhuis NC Division of Water Quality Wilmington Regional Office 127 Cardinal Drive Ext. Wilmington, North Carolina 28405 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 H1 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 ■ TEL 919 677 2000 FAX 919 677 2050 ■ P.0 Box 33068 Ralegh, North Carolina 27636 -3068 CMn I{imley -Hom Associates � and , Inc. 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.
