Brian,
This is in response to our phone conversation on Feb. 1st, 2022, and per our previous emails and conversations.
Per your request, I have revised the Stormwater Pollution Prevention Plan (SPPP) and Pumping Dewatering
O&M Plan for the Pete Morton Pit. See attached. I revised it to include more information about the dewatering
of the mine. See Page SPPP-2.
In addition, I revised the Sediment Basin Chart Calculation on the Mine Site Plan.
We have staked the mine boundary and Tim Morton stated that they put up some PVC pipe along the boundary
to help mark it.
Tim Morton said they have worked on the Construction Entrance and have almost finished cleaning out and
repairing the existing sediment basin.
Let us know if you want to have a Site Meeting to review all of this and we can meet you on site. If you have
any questions or need any additional information, let me know. Thanks.

This email is in response to the letter by Dan Sams dated November 29, 2021 and my follow up emails and
phone conversation with you.
As discussed, we submitted for the NPDES Stormwater General Permit NCG020000, July 2019, you stated that
NCDEQ did receive the application, but the permit was never issued.

I reviewed the Sediment Basin Chart Calculation on the Plan, and the calculations show that the basin and the
skimmer is sized adequately to handle the 18.6± acres of mine excavation area. See attached.
Morton Trucking is in the process of cleaning out and making repairs to the sediment basins, so that it will
work properly. The weather and the holidays has delayed their completion.
Morton Trucking is also in the process of making repairs to the construction entrance and marking the mine
boundary, as requested.
If you have any questions, or need any additional information, please let me know. Thanks.

STORMWATER POLLUTION PREVENTION PLAN (SPPP)
AND PUMPING DEWATERING O & M PLAN
FOR PETE MORTON PIT
July 2019
Revised February 2022
SCOPE
The intent of this plan is to provide a detailed plan/guide for the Operation and
Maintenance of the Pete Morton Mine so that it complies with Part III Section A of the
NPDES General Permit No. NCG020000 for Mine Dewatering. This plan has been
prepared by Parker & Associates, Inc. July 2019, and has been revised by Tidewater
Associates, Inc.
1. SITE PLAN
A. See the attached Exhibit 1 — Color Portion of Kellum USGS map, and Exhibit
2 — Portion of Onslow County D.O.T. Map, and Mine Site Plan.
B. The Pete Morton Mine is a proposed sand mining operation only. Sand shall
be excavated and loaded directly into trucks and hauled off site to other locations.
Loading shall be performed with an excavator. Other than normal daily maintenance, all
equipment service shall be performed off site. No fuels or lubricants shall be stored near
or in the mining area. Excavated material is normally wet so dust should not be a problem
in mine. The haul road shall be monitored and periodically dampened utilizing a water
truck when necessary to control any dust created from hauling operations. There shall be
no waste generated from this operation, therefore, no disposal plan is needed. The
possible pollutants to be concerned with are small amounts of fuel or hydraulic oil
created by a ruptured hose or pipe on trucks or equipment. This should not be a normal
occurrence but in the unlikely event that it does happen there always shall be someone on
site to minimize and contain the spill before it reaches any water source. Any
contaminated soils shall be removed and disposed of at a facility certified to treat soils.
C. See the attached Mine Site Plan by Tidewater Associates, Inc.
306 New Bridge Street I P.O. Box 976 1 Jacksonville, NC 28541-09761 [phone]
Firm License Number F - 0108 1 www.tidewaterenc.com

D. There have been no significant spills or leaks at this location, therefore, no
corrective actions have been needed.
E. Dewatering — The mine shall use a floating dewatering pump. It shall
be located in the Mine Excavation Area. Upon initial excavation of the mine, a sump pit
in the area where the floating pump is to be located shall be excavated to 15' deep. Upon
the sump pit filling up with water, the floating pump shall be installed.
The pump shall be capable of pumping 1000 GPM. It shall pump into the rip rap
lined portion of the skimmer sediment basin as shown on the Plan. The sediment basin
shall be constructed 4' deep, below the elevation of the skimmer discharge elevation.
The temporary volume of the basin shall be 2.5' above that elevation, and contain the
storage volume as shown on the Plan.
The temporary volume of the skimmer basin is 1,241 cubic yards. This is
approximately 250,600 gallons, which will allow approximately 4 hours of pumping time
using a 1000 GPM pump. Once the basin is full, the skimmer will dewater the basin
from the top of the basin water. If the water in the mine, or at the skimmer discharge
appears turbid, pumping shall cease until the sediment settles and water at the top of the
basin appears clearer.
During periods of no rain, it is anticipated that the pumping will be for ground
water only and the pumping time should be less. After a rainfall event, pumping time
should be more. The operator shall keep a log of the pumping dates and amounts.
The discharge pipe for the floating dewatering pump shall be inspected daily
when pumping. The discharge line is located in close proximity to power source for
pump and immediately after starting, pump discharge shall be evaluated to determine if
any turbid discharge is present. Pumping shall be performed only as needed and never
immediately after or during a rain event. Water shall be drawn from just below the
surface (6"-12") of the water to pump the clearest water. Visual checks for clarity shall
be performed each time the pump is operated. Any foam, discoloration or unusual odor
shall result in immediate shut down of pump and discharge.
The sediment basin shall be maintained monthly or as needed to maintain the
volume of the basin, and to assure the baffles, and the skimmer are operating properly.
Samples shall be collected and analyzed by a certified laboratory as required in
the NPDES General Permit — NCG020000 and results shall be kept on site. Results shall
also be forwarded to NC DEMLR annually as required by the General Permit. At any
time sampling results exceed acceptable levels, discharging shall cease until conditions
become more favorable and samples shall be taken monthly for a period of one year or as
outlined in the General Permit. After such time, if levels have been consistently lower
than acceptable levels, samples shall be drawn on a quarterly basis at minimum or as
deemed necessary. Daily records shall be maintained on site recording times and amounts
of pumping as well as recorded rainfall.
SPPP - 2

2. EROSION AND SEDIMENTATION CONTROL
The site shall install and maintain all erosion control measures shown on the
approved mine site plan.
There shall be no gravity discharge of stormwater from the mine, directly into the
adjacent wetlands or creek; therefore, there are no special erosion and sedimentation
control measures, except as shown on the Plan. The dewatering discharge shall pump into
a rip rap lined basin, then flow through the sediment basin prior leaving the basin through
a skimmer then flowing into the wetlands, then flow through couple hundred feet of
wetlands prior to reaching the creek. The facility shall be operated and maintained in
compliance with the Mining Permit and the NPDES General Permit issued by the
Division of Energy, Mineral and Land Resources.
3. STORMWATER MANAGEMENT PLAN
A. All excavation and land disturbance shall be confined to the mine area with
only one controlled discharge source (dewatering pump). Natural grade in the area
prohibits stormwater run-on into the mine. All areas, outside the mine, sheet flow to
wetlands away from mining area. No discharge of stormwater (pumping) shall occur until
all solids have settled and water is clear.
B. An inspection of the mine slopes, construction entrance/exit, and dewatering
devices shall be conducted weekly or within 24 hours of any storm event by the mine
operator or other competent person. No discharge shall take place during or immediately
after a storm event. A rain gauge shall be kept on site and monitored and all rainfall
recorded. A record of inspections, deficiencies and corrections shall be recorded and kept
on site.
C. There shall be no bulk storage of any kind on this site.
4. WETLANDS MONITORING
The adjacent wetlands shall be monitored annually by a Soil Scientist to
determine if the mine dewatering is having a detrimental effect on the wetlands. A yearly
report shall be filed and kept by the mine operator. If it is determined that the wetlands
are being affected, a mitigation plan shall be developed by the Soil Scientist and
presented to NC DEMLR for approval.
5. SPILL PREVENTION AND RESPONSE PLANUSPRP)
There shall be no bulk storage of any kind on site; therefore, there is no potential
for spills.
SPPP - 3

6. PREVENTATIVE MAINTENANCE AND GOOD HOUSEKEEPING PROGRAM
All equipment and trucks shall be kept in good working order and kept on a
regular maintenance schedule. Operators shall be trained and required to inspect
equipment prior to starting work each day and periodically throughout each shift.
Operators shall look for fluid leaks as well as potential leaks and shall not use equipment
if any problems are found. All equipment with any type of leak shall be removed from
mine immediately and repaired. Equipment shall be removed from mine and washed
periodically to prevent rainwater from washing contaminants from machine onto ground.
All equipment shall be checked by mine operator or qualified mechanic weekly.
7. EMPLOYEE TRAINING
Training for all involved in mine operation shall be required annually. This
training will include safety, things to look for that could possibly contaminate water,
equipment inspections, and instructions on what to do if a spill occurs. All new
employees and anyone working in mine area shall be required to receive training before
entering mine. Training shall be provided by mine operator. Mine operator shall stay up
to date on new references and resources pertaining to mining safety and stormwater
management.
8. RESPONSIBLE PARTY
The Mine Operator shall be responsible for overall coordination, development and
implementation of the S WPPP, and all mine and dewatering practices. He shall ensure
that all requirements are met and all records are up to date. The Operator shall be also
responsible for training of employees and personnel.
9. PLAN AMENDMENT
The SPPP shall be reviewed annually and amended as needed and all changes
incorporated into training and Best Management Practices.
10. PLAN IMPLEMENTATION
The SPPP shall be implemented immediately upon approval and a copy
maintained on site. Additional copies of the plan and recorded data shall be provided
upon request. Information shall be kept on site for a minimum period of five years and
made available to NCDEQ upon request.
