MILL CREEK SAND AND GRAVEL MINE # 59-40
G.S. MATERIALS
NPDES NCG020000 DEWATERING PERMIT
JOHNSTON COUNTY, NC
DESIGN NARRATIVE
2/10/2015
MINE LOCATION AND PERMIT
The mine is located northeast of Newton Grove along the Johnston and Wayne County line. The
GSM mine office is located offsite in Harnett County, but an onsite office and scales handles any local
material transport. The total mine acreage is 51.20 acres with a maximum of 43.64 acres allowed for
excavation. Current operations have mined in wet and dry conditions. Future operations are
proposing to dewater an existing clearwater pond for additional mining to pump into and drain offsite.
STORMWATER CONTROL MEASURES
Given the existing clearwater pond onsite, there is no additional proposed stormwater best
management practices other than a surface withdrawal device proposed to be installed for the pond.
There are a series of tailing ponds that feed the clearwater pond, so they act as significant forebay
storage volumes for settling fines. The existing clearwater pond was evaluated to determine the 10-yr
and 25-yr flood storage in order to meet NCG02000 Permit Condition Part III, Section B that reduces
analytical and qualitative monitoring depending on the design storage results. Based on routing the
storms with Hydraflow Routing software, the total volume of the clearwater pond exceeds the 25-yr
storage. Depending on future mining operations, this pond may be reduced, and therefore a design
was determined to meet the minimum 25-yr control. The attached drawing shows this minimum sized
pond to control the 25-yr storm. The skimmer outlet device has been designed in accordance to NC
Erosion Control Manual Sections 6.61 and 6.64. The skimmer will discharge below 1.0 cfs
continuously per day for approximately 3 days to drawdoWn the storm water column. The 8.0 inch
skimmer was selected based on the Marlee Design Table designed and published by Jamie
McCutchen, PE of Fee Saver Stormwater Services. This product is manufactured with more UV
resistant materials than white PVC to last longer and utilized for more permanent drainage
applications. See attached routing and Marlee Skimmer design package.

Dear Engineers and Contractors,
As most of you are aware, at the beginning of this year South Carolina implemented a new requirement for
surface withdrawal or skimmers to be used in sediment basins. Leading up to this new requirement I had
heard several contractors voice their concerns over skimmers, mainly maintenance issues (getting stuck in the
mud or clogged) and durability (most are made of PVC).
In December, 2012 my daughter, Marlee, had a restless night and wanted to sleep with my wife and me. She is
restless sleeper and after a few hours of elbows and knees in my back, an idea came to mind for an alternative
skimmer design. I got up and sketched out the concept. Over the next few months we developed. prototypes,
tested them and filed for a patent. After several trials we came up with a design we felt would work and a
name —The MarleeT" Float.
In August we were able to install a prototype in a sediment basin for field testing. Shortly after that we
completed third -party testing, confirmed device approval with SC DHEC and NC DENR and applied for SCDOT
and NCDOT approvals. So far we have several in use on projects in Upstate South Carolina and contractor
feedback has been very positive.
There are several significant differences between our skimmer and others on the market. These include:
i It is made of HDPE and stainless steel, so it is UV -Resistant and virtually indestructible
The shielded orifice design withdraws water from just below the surface, enhances sediment
trapping efficiency and prevents floatables from escaping.
The orifice is well protected from mud and debris, therefore, much less likely to clog.
The device is extremely buoyant and the design keeps it from settling into the mud, both of
which prevent it from becoming stuck.
Because it is not prone to clogging and does not break down in sunlight, our device is an
excellent alternative to small low -flow orifices as part of the permanent outlet system.
Complete design information, including details in CAD and PDF formats, flow rates, cut sheet/installation
instructions and third -party testing results are available on ourwebsite—www.swfeesaver,com. We also have
videos to demonstrate how the skimmer works and how to install. We will be adding design aids based upon
specific requirements of each state as they come available.
Our website includes information on local distributors in your area that carry our device, or if it is not locally
available we will be glad to ship it to you. If you have any technical questions you can contact Jamie
McCutchen or for sales contact TL Baldree. You can reach us at 1-SSS-MY SWFEE (697-9333) or through the
website.
Sincerely,
0IM,
Jamie McCutchen, P.E.

Subject: Marlee"A Float Skimmer
Dear Engineers and Designers:
Please find enclosed a product brochure on the Marlee'm Float skimmer by SW FeeSaver, LLC. This is a
new skimmer/surface drain device that has been confirmed to meet EPA, SCDHE=C and NCO£NR
requirements for skimmers. Approval by SCOOT and NCDOT has been applied for and is pending,
In addition, this product has been third party tested by TRI Environmental to confirm flow rates and
draw down times. Details, including flow rates, installation instructions and third party test results are
available to download from our website — www,swfcesavcr,corn, We are currently developing design
tools and instructional videos to aid In incorporating the Marlee'' Float into your plans and
specifications.
Because the product is made of HOPE and its unique design minimizes clogging, we recommend it for
use In temporary and permanent basins, especially when low flows are needed to meet water quality
requirements.
We understand that engineers are looking for products that meet regulatory requirements and function
on the job site. We also understand that skimmers are a relatively new requirement In many areas and
there are still questions on how to Incorporate them Into basin designs, If you have any questions
regarding this device or any concerns regarding its use in your area, please call me at 1-855-697.9333 or
email me at 1mle0Vfecesavar, co_M.

1. 5" - 8" Marlee Float Skimmer is to be attached to a 6" rigid pipe (Schedule 40 PVC for construction/temporary
applications or HDPE for permanent applications). Rigid pipe should be 1.5 times the height of the outlet
structure. For ponds requiring a pipe length greater than 12' additional weight may be required to counteract
buoyancy.
2. 6" Rigid pipe to be attached to 8" pipe stubbed out of outlet structure or through dam. Flexible coupling to
attach 6" rigid pipe to 8" PVC or HDPE stub out is provided. If 8" stubout is material other than Schedule 40 PVC
or HDPE an alternate coupling may be required.
3. When installing couplings make sure to leave at least 1" space in coupling between pipes to allow for sufficient
flexibility. This is particularly important when using coupling to like size pipes (i.e. 6"x6" ).
4. Basin should have a 12"-18" depression (skimmer pit) to effectively drain pond. Two to three inches cr water
may remain in bottom of skimmer pit. It is recommended to slope basin at 2% grade to skimmer pit.
5. Skimmer is shipped fully assembled. Top weight can be removed for ease of installation by removing wing nuts.
Take care to replace rubber stoppers, washers and tighten wing nuts securely once installed. User attaches
flexible couplings to rigid pipe and stubout from outlet structure. Securely tighten pipe clamps and install two
screws (provided) through each connection to minimize slipping.
6. During installation take care to position skimmer in upright position with floats level. Also verify that vent hole
in flexible coupling is rotated to top of pipe.
7. 5" and 6"Orifice saddle is provided to convert standard 8" orifice. Center hole in saddle over 8" hole and secure
using two pipe clamps provided.
8. Add maintenance rope, if required.
9. Flow rates are provided with details. Design engineer to select skimmer size as required to meet local
requirements. For technical support and/or assistance with installation, visit our website at
www.swfeesaver.com or call 1-855-697-9333.
