Dear Sirs:
On August 15, 2003, the Wetlands/401 Unit of the Division, Of Water Quality received
your application for wetland impacts as with the expansion of the Rocky Point
Quarry located near Hwy 210 and I-40 in Ponder County. On August 22, 2003, the
Wetlands/401 Unit issued a hold letter, This letter stated that the application would not be
considered to be complete until a copy of the Public Notice from the U.S. Army Corps of
Engineers was received and that at that time additional information may be required. As
such, after review of the completed application package, received December 1, 2003, we
believe that your project should be place on hold. We will require you to address the
following items in order to allow appropriate review of your project to continue pursuant to
15A NCAC 2H,0506 (b) (1) -(6) and ISA NCAC 2H .0506 (c) (1) -(6).
•l, Your application indicates that Martin Marietta Materials (in the future) intends to
pursue development of the mine site to the south (tract E). It is the understanding of
WQ staff that areas to the south have notably fewer jurisdictional wetlands than the
roposed expansion areas (G1 and G2), please document (provide County zoning
letters, landowner information, DLR correspondence, drilling reports etc.) as to why
impacts to the proposed wetlands may not be avoided by proceeding with the mine
expansion to the south, rather than the east. 0 11 nn J J
Please indicate whether Xtexcavation and dewatering of the mine pit may affect adjacent wetlands.This discussion should clearly explain whether such
activities will result in hydraulic gradient alteration, thereby draining/reducing 4
adjacent wetland areas, (A written account addressing this issue/information,
monitoring data, and modeling used for this account needs to be submitted to DNQ
for use as a part of this application review),

Please clearly indicate the amount of buffer to be established around the mine
edge and the respective wetland edges (show the buffers on a plan). Are there
wetlands that are not proposed to be impacted located within this buffer? If so, will
these wetlands be drained from the gradient change and pumping of the mine?
Specifically, explain whether the wetlands on tracts G1, G2, H1 and H2 and beyond
Martin Marietta Materials property line will be impacted by mining and ravine
dewatering?
Provide a wetland delineation for tracts known as H1 and H2, a C01F
A pumping plan must be provided and an implementation schedule that clearly
explains how wetlands within G1 and CG2 will be maintained through the mine
dewatering efforts. A monitoring plan must be included as a part of this plan.

6. It was explained that Martin Marietta Materials is intending to pump water to a
neighboring tract to create an impoundment. Please provide plans, an account of this
activity, the pathways for conveying the water to the site, frequency of pumping,
?g a volume of ptunping, and the location of this proposed activity.
7. Please provide a wetland monitoring plan for the tract. Specifically, data is to be ?
collected to insure wetlands that are proposed to be avoided are adequately
-N? monitored. This plan should address the tracts G1, G2, H1, H2, the jurisdictional
areas within tract E, any areas that are to be "re-hydrated", and a "control" wetland ,
site (that must be located 5000 feet or further from the mine edge).
8. A rain gauge station must be developed for the proposed mine site and a "control"
wetland site, You must provide an account explaining how the rain gauge will be
properly maintained, daily iufbrmation recorded, and the results maintained, Please
provide a map depicting where the rain gauges will be safely and properly positioned,
9. As a part of the monitoring plan, a map must depict the landscape position of all
wetlands, ditches, proposed well placement, borrow areas, stormwater controls, and
the- mine footprint. The plan must include an account of the frequency of wetland
physical monitoring (efforts to periodically reaffirm the presence of the jurisdictional
wetland line and soils) well data collection, well inspections and maintenance, data
analysis, and reporting, (Note: Monitoring must continue for a period of 5 years post
mine pit closure).
10, This monitoring plan must specifically include a clear account (methodology) of how
monitoring data will be analyzed to determine whether wetland hydrology persists or
if the wetland has been concentrically reduced within the given wetland polygons.
11. If monitoring results indicate impacts to the avoided wetlands or wetland that are
being "hydrated" please explain how these impacts may be abated, (Martin Marietta
must include contingencies in the pumping plan necessary to abate unauthorized.,
impacts to wetlands.)

12. In order to address cumulative and secondary lmpa ts, and to account for wetland
standard concerns associated with tracts F1, F2, and a mined portion of G2 please
address the following;

a. When (dates) did the USAGE make Jurisdictional determinations for Tracts
F1, F2 and the mined portion of 02;
b, Provide aerial photographs that predate and postdate the USAGE
Jurisdictional determination of F1, F2 and trained portions of G2;
c. Provide an account of the wetlands that were impacted by the mine face. That
is, explain and provide a total acreage of wetland impacts that were impacted
by the mine (excluding the influence of forestry and road side ditches) from
October 1, 1996 to present for tracts F1, F2 and the mined portion of tract 02.
Clearly explain how this determination was made (e.g. DRA11rT1VIOD, aerial
photos, soil surveys etc.);
d. Respectively, address how you plan to replace the impacts to wetlands (e,g.
on-site restoration, '1AW, etc.).

13. Please discuss the onsite wetland restoration opportunities available for mitigation C OC -J S
consideration. r,` I ;U r
14. Please provide a Jurisdictional Determination Map signed by the U.S. Army Corps of
Engineers for all tracts of land with proposed wetland impacts and for any adjacent
tracts that have been determined by the COE to be non jurisdictional.
Please provide the Wilmington Regional Office (WiRO) and Wetlands/401 Unit at (2321
Crabtree Blvd„ Raleigh, NC 27604,2260 (attention Danny Smith)) copies of the above listed
items,' In addition, please provide an additional copy to the WiRO, with an appropriate cover
letter that indicates that this response represents your proposed pumping and monitoring
plans necessary to address NPDES Permit conditions.
-If you have any questions or would require any additional information please contact
Daiuiy Smith at [phone] or Noelle Lutheran at [phone], This project will
remain on hold as incomplete in accordance with 15A NCAC 2H .0305(c). The processing
time for this application will begin when this information is received. If we do not hear from
you by writing within thirty days (30) we will assume you no longer want to pursue the
project and will consider it withdrawn.
Sincerely,
