HomeMy WebLinkAboutWQ0004268_System Description_20090225System Description
Aliens, Inc. - Plant #7 is a vegetable canning operation located in Turkey, North Carolina. The
existing wastewater treatment and disposal system consists of two stationary screens, one screw
press, a primary lagoon, a storage lagoon, and a wastewater spray irrigation system located along
Rowan Road. The proposed permit modifications in this submittal include the following
equipment:
• Screening facility with four (4) stationary screens, two (2) screw presses, one (1) storage
hopper, one (1) closed -loop recycle water storage tank and one closed -loop recycle water
pump
• Irrigation pump station, wet well, intake Structure with wooden dock, and well house
• Approximately 11,600 linear feet DIP or HDPE forcemain
• 244 Spray Irrigation heads and associatedirrigation piping and valves
With this permit modification, no increase in the design flow is proposed. The existing primary
and storage lagoons will remain in service. Once the new pump station is online the existing
pump station will be abandoned. The existing irrigation zones will be connected to the new
forcemain.
Currently the wastewater flows out of the canning facility :into a submersible pump station. This
pump station feeds both stationary screens at the existing screening facility. Solids separated out
by the screens are conveyed to. the screw press while the water flows by gravity to the primary
lagoon. The solids enter the screw press where the water is removed and piped to the lagoon.
Solids are emptied into a hopper for storage until they can be used or properly disposed of
Water removed by the press is piped to the primary lagoon. Primary lagoon effluent flows into
the storage lagoon where it is irrigated onto the adjacent fields.
The proposed system is expected to operate very similar to the existing system. Differences
include additional capacity for solids removal at the screening facility and a gutter flush return
pump with a closed -loop recycle water storage tank to flush drains inside the canning facility.
An upgraded pump station with Variable Frequency Drive (VFD) pumps will irrigate the existing
irrigation fields and the proposed field across Rowan Road. The proposed irrigation design uses
a solid set system with impact sprinkler heads.

Operation and Maintenance Plan
System Operation
The proposed screening facility wilt,operate automatically as the existing pump station doses the
stationary screens. The screening facility is set up to operate in two trains, with each train
operating two stationary screens and one screw press. Manually operated valves will allow the
operator to dose either of the trains, or isolate pieces of equipment for required maintenance.
Augers will transport the vegetable screenings to the screw press. After the water is pressed out
the vegetable screenings will collect in a hopper. The screenings will be stored until they are
manually emptied into a truck using the discharge auger(s):
Water from the screening facility will flow by gravity to the primary lagoon or the closed -loop
recycle water storage tank. The Closed -loop recycle water pump moves water back to the plant to
flush the gutters used for transporting vegetable waste out ofthe plant Settling will occur in the
primary lagoon prior to the effluent entering the storage lagoon. The irrigation system will draw
water out of the storage lagoon to dose to the irrigation. fields. The pump station contains three
main irrigation pumps and one jockey pump. A variable frequency drive (VFD) set up is used to
control the pump operation. Valves will be manually operated in the field to dose the desired
irrigation zone. As valves are opened and closed the VFD will automatically adjust the flow
based on the pressure changes. The pump station contains a jockey prunp to maintain the desired
discharge pressure during low flow fluctuations.
All system operation should be performed by the Operator in Responsible Charge (ORC)
or someone working under his direct supervision.
Inclement Weather Operation
The Operator will track and record rainfall, air temperature, and weather conditions on a daily
basis and report this information on the Discharge Monitoring Report (DIvIR). Due to the
manual nature of the irrigation system an operator will be on -site during a vast majority of the
irrigation periods. Weather forecasts and actual site conditions will be used to monitor for
pending or actual rah.). events. Irrigation is stopped if inclement weather is imminent or has
occurred. Visual inspections of the field conditions will be used to determine the acceptable time
to commence irrigation after rain events.
Safety Measures
Access to the proposed pump station and existing irrigation fields is restricted by the security
guard at the plant entrance. The pumps are protected on other sides by natural obstacles such as
wetlands and the irrigation lagoon.

Wastewater Treatment System Improvements
MacConnelf & Associates,P.C. Project No.: A30701.00 and A30705.00
The proposed irrigation fields on Rowan Road will be protected from public access by a two
strand barbed wire fence and a gate on the Rowan Road (north) side of the irrigation field. The
Beaman Woods Road (west) side of the field will be fenced from Rowan Road to the woods line.
Access along Beaman Woods Road in the woods line is also restricted by a cannel. Access to the
irrigation fields on the other south and east side are restricted through natural buffers such as
creeks, woods, and wetlands, therefore additional fencing will not be necessary.
Crop Harvest and Removal
Winter Rye crops should be cut and removed (bailed) in the spring to prepare for a re -growth of
Coastal Bermuda. Coastal Bermuda crops should be cut and removed in the fall prior to seeding
of winter rye. Recommendations in the agronomist report by S&EC and the provisions in the.
Division of Water Quality permit should be followed at all times.
During harvesting periods, sections of fields are taken out of rotation to allow ample time for
cutting, drying, and bailing. Generally this process takes 3 - 10 days depending on drying and
weather conditions After the completion of one section, another section is taken out of service
and the cutting, drying, baling process is repeated. The additional capacity of the Rowan :Road
fields will allow tune for harvesting sections of the fields and keep up with the wastewater
generated by the canning facility. Harvesting should always follow good agricultural practice
and the recommendations of North Carolina State University, Sampson County Extension Office,
and Soil & Environmental Consultants (agronomist). The :harvested crop is used for cattle feed.
*All harvested (mowed) crops shall be removed from the site.
