Subject: NPDES Compliance Evaluation 1ps ction
NPDES Permit COC #NCG020 18 and NCG020349
Brunswick County
Dear Mr. Smith,
A compliance evaluation inspection of the two mining facilities was conducted on October 13, 2009. This inspection was to verify
that the facilities are operating; in compliance with the requirements specified in the NPDES General Permit NCG020000. The
findings and comments noted during this inspection are provided in the enclosed copy of the inspection report entitled "Compliance
Inspection Report".
In general, good housekeeping and best management practices appear to be in place at both sites. The quality of the water within the
mine pits were exceptional. There were no discharges evident at the time of the inspection. There are some deficiencies with the
requirements of the permit and are noted in the inspection report. This office is providing a compliance schedule of December 1, 2009
to address the deficiencies noted. If you need more time, you should contact this office no later than two weeks from the deadline date
provided. Your cooperation during the inspection was greatly appreciated. Should you have any questions concerning this
correspondence or the enclosed inspection report, please contact me at 910-796-7343.
Sincerely,
Linda `'Willis

Permit: NCG020618 Owner - Facility: Wayne Smith
Inspection Date: 10/13/2009 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
The following are requirements imposed as a result of the site inspection:
1. A wetland delineation verification by USACOE should be conducted. If the permittee choses not to verify the wetlands,
this office has no choice but consider the isolated pockets identified by Land Managment Group wetlands and waters of
the State, whereby analytical and qualitative monitoring will be required quarterly and semi annually (respectively).
Section C of the permit will apply for dewatering activities. Qualitative monitoring will apply as well semi annually when
dewatering is occuring within the time periods identified in the permit. A copy of the permit is being sent along with a copy
of the COC (certificate of coverage). An O & M plan will be required as well which explains the dewatering activity
(number and sizes of pumps, pumping frequencies and velocities of discharge. The permit identified the use of a level
spreader to dissipate the flow, no level spreader was present. If a level spreader is used, please provide the design with
the O & M plan.
2. Should the USACOE determine the pockets identified by LMG as non wetland, those areas are not considered waters
of the State and therefore the discharge to those areas would not require monitoring since it does not appear that those
areas have hydraulic connectivity to Standbury Creek (closest surface waters in the area). It would also not trigger a
requirement for an O & M plan.
This office will require the permittee to provide a copy of the mine site map for our records. Any questions concerning this
request can be directed to Linda Willis at 910-796-7343. The inspector is calling this inspection neither compliant or non
compliant. However, further action by the permittee is required and will be expected no later than December 1, 2009.

Permit: NCG020349 Owner - Facility: Wayne's Backhoe Service
Inspection Date: 10/13/2009 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
This site should have an O & M (operation and monitoring) plan that includes:
1. A map of the mine site with the mine site layout, the series of mine pits and the various directions in which water may
be pumped or flow. All ditches (conveyances) must be identified on the map. A geographic map (google map is
fine)should be provided as well that shows the mine site and it's proximity to any and all surface waters including
wetlands.
2. If and when the pits discharge to the ditch system that feeds the small wetland, the permittee will be required to
conduct analytical sampling where the discharge enters the ditch. If it pumped to a ditch, the outlet of the pipe from the
pump would need to be monitored. This would need to be done each quarter in which there is a discharge. The
discharge from the pit needs to monitored analytically if the discharge is due to stormwater control as well. It would be
prudent to inspect the mine pits to determine whether any rain event results in a discharge. This would be considered a
discharge in which the quarterly monitoring is required. See attached permit for details on which parameters are required
for monitoring. (Section C)
3. If the pit requires pumping for control of pit water, the permittee needs to specify what size pumps may be used, the
size of hose, an estimated velocity of discharge, an estimation of the settling basin sizes that can provide adequate
detention time before discharge. A worst case pumping scenario should be used to demonstrate adequate settling
detention time.
4. The O & M plan needs to be sent to the Wilmington Regional Office at 127 Cardinal Drive Extension Wilmington, NC
28405. Send it to the attention of Linda Willis. The operation plan should be completed and sent to this office no later
than December 1, 2009. Should you have any questions concerning the operation and monitoring plan, please do not
hesitate to contact Linda Willis at 910-796-7343. Revisions to the plan may be recommended after this office is in receipt
of the mine site plan and operation plan.
The overall appearance of water in the pits was of exceptional quality the day of the inspection.

Comment: SWP3 is not required by this permit. The permittee is required to provide
an 0 & M (Operation and Monitoring plan). No monitoring wells will be recommended at
this time. An operation plan should be developed to identify the methods available for
providing adequate settling times in each basin based upon the size of the basins
available for settling. If pumping is required, the operation plan must identify the
number and size of pumps and pumping frequency (worst case) expected.
Qualitative Monitoring Yes No NA NE
Has the facility conducted its Qualitative Monitoring semi-annually? ❑ ®❑ ❑
Comment: Permittee must start conducting qualitative monitoring semi annually during
any discharge event occurring within the first and second half of the year. Please see
attached permit for qualitative monitoring requirements. There is a potential for
discharge to surface waters. Any dewatering activity must be evaluated to determine
whether input to the ditch system that discharges to the small wetland on site is
occurring. Furthermore, any stormwater discharges from the designated mining area
that does not discharge internally to the system of pits (ponds) must be evaluated for
the qualitative parameters (at least semi annually) in accordance with Section B of the
permit.
Analytical Monitoring Yes No NA NE

Comment: There were no discharges from the mine pit during the site inspection. The
Wilmington Regional Office (DWO) does not have a copy of the mine map (please
provide this office a copy for our records). The permittee has created a series of long
pits all interconnected by overflow structures with wooden wiers as means to control
water levels in the series of pits. These pits do have connectivity to surface waters via a
ditch system that ultimately discharges to a small wetland on site. It is recommended
that the outfall from the last pit in series be the discharge that is monitored both
qualitatively and quantitatively when active dewatering is occuring.

Comment: Enclosed is a copy of the Certificate of Coverage for this mine site. Please
be sure this is in your records and when requested by the inspector can be produced
that day. The mine site did not appear to have any issues with erosion that would result
in water quality violations. The system of pits appear to provide a "chain" of settling
basins that can be used to provide adequate detention time as long as the wiers are
used as the sole control for water levels. Inspector cannot comment at this time on
whether pumping activities would provide adequate detention time.
