ATC SUMMARY
SCOPE
Norfolk Southern Railroad
Linwood, NC
ATC No. ACA029246
High Rock Lake, Class WS-V
Yakin River Basin, 030704
Davidson County
The scope of the project includes the replacement of an existing clay lined equalization lagoon with
an aboveground carbon steel storage tank, lining of the lagoon, and installation of a pump station.
RECOMMENDATIONS
1. Approve modification of existing equalization lagoon. Lagoon will be lined
and divided in half to accommodate a new pump station and additional
emergency storage capacity for wastewater.
2. Approve installation of a new, 2.3-MG carbon steel storage tank for
equalization.
REVIEW SUMMARY
Executive Summary
The subject facility has operated a Class II pollution control system since receiving an
Authorization to Construct (ATC) in 1988. The most recent NPDES permit became effective on
March 1, 2000. The treatment works currently consist of:
•Track collection pans
• Bar screen
• Grit chamber
• Oil skimmers
• Equalization basin
• Chemical feed
• pH adjustment
• Dissolved air flotation unit
• Flocculation
• clarifier
• Aerated polishing pond
• Flow meter
• Sludge Drying Beds
This proposal is a voluntary measure that will increase the overall equalization capacity in the
system. The plans are compatible with the existing process train; it is therefore recommended
that the project be approved.

Project Description: Replacement of an existing clay lined equalization lagoon with an
aboveground carbon steel storage tank. Part of the lagoon will be lined to provide additional
emergency storage capacity. The remainder of the lagoon will hold the new pump station, designed
to transfer incoming process wastewater flow to the new equalization tank. Stormwater pumps will
also be provided to transfer any stormwater runioff that exceeds the design capacity of the process
pumps. The old equalization basin will be grad %o that any excess volume of stormwater held in
the lagoon will eventually drain back to the pump station.

Pump Station
Number of process pumps: two (to be operated as lead/lag)
Type: ITT Flygt CP 3127 Impeller 483, 10 hp (460 v, 3 phase, 60 Hz motor) constant speed
Design Operating Capacity (gpm): 300
Note: The process pumps are to operate as lead/lag pumps. When wastewater level in the wet
well rises to 3.5 ft., the lead pump starts; at a level of 4 ft., the lag pump starts. Both pumps then
shut off when the level in the wet well decreases to 2 ft.
Number of stormwater pumps: two (to be operated as lead/lag)
Type: ITT Flygt CP 3201 Impeller 639, 40 hp Capacity constant speed
Design Operating Capacity (Gpm): 1500
Note: The stormwater pumps are to operate as lead/lag pumps. When wastewater level in the wet
well rises to 5.5 ft., the lead pump starts; at a level of 7 ft., the lag pump starts. Both pumps then
shut off when the level in the wet well decreases to 2 ft.
Carbon Steel Tank:
Type: Open top, field erected, welded carbon (ASTM A36) steel tank
Volume: 2,408,500 gallons
Dimensions: 32-ft. high, 115 ft. in diameter
Review Notes:
For pump station:
Checked design calculations (including verification of head loss calculations — see attached Excel
printout) and pump curves. Reviewed design plans to ensure that no bypass can occur. Provisions
have been made for standby power and an alarm system with manual reset. The pump station can
be started automatically or manually and can be shut down several ways. Standby power will be
provided in the form of a diesel engine coupled to an AC generator unit. Duality is achieved since
there are two individual units of each of the two types of pumps.
Flow meter and all associated controls have been included in the plans and specs.
Equalization basin:
Side slop eof 2:1 was verified. Provisions have been made for emergency overflow that yields a
greater overall equalization capacity than exists currently.
All flows entering into the system go to the next treatment stage (aeration).
Chemical Storage: There is no chemical feed in the proposed treatment unit design.
Material Compatibility: Materials are compatible with the proposed application.
Compatibility with existing equipment: The proposed project is compatible with the existing
treatment system and adds an additional storage capacity beyond what is required by the facility.
Recommendations
I recommend that the Authorization to Construct be issued in order to increase system
capacity.

Stormwater Pond Upgrade
Authorization to Construct
Telephone
Dear Mr. Weaver:
864.234.3000
On behalf of Norfolk Southern Railway Corporation, Earth Tech hereby requests an
Authorization to Construct the wastewater treatment facility modifications presented in the Facsimile
attached plans and specifications.
864.234.3069
The proposed modifications essentially replace an existing clay lined equalization lagoon
with an aboveground carbon steel, storage tank. The proposed 2.3 MG tank is 115' diameter
x 32' high. While this volume does not match the current 4.7 MG capacity of the existing
lagoon, this lagoon will be lined as part of the project and will provide additional emergency
storage capacity of approximately 3.6 MG. The total increase in storage capacity provided by
this upgrade is approximately 1.2 MG or a 25% increase.
A new pump station will be constructed in the bottom of the lined Iagoon. Process pumps
designed to provide 300-gpm will transfer incoming process wastewater flow to the new
equalization tank. Stormwater pumps designed to provide 1500 gpm are provided to transfer
any stormwater run-off that exceeds the design capacity of the process pumps. During major
storm events when the pump station is unable to keep up with the storm flow, the excess flow
will over flow into the lined basin. The basin will be graded so that the excess volume will
eventually drain back to the pump station where it will be pumped into the storage tank.
Wastewater will flow by gravity from the equalization tank into the existing API separator,
which is the first unit of the wastewater treatment system. A flow control loop utilizing a
magnetic flow meter and motorized flow control valve will be provided to allow the operator
to "set" a flowrate at which he wants to operate the plant.
Regarding submittal requirements, enclosed with this letter are:
1. Three sets of the Detailed Plans and Specifications, which are appropriately stamped.
2. Two sets of Design Calculations. (We take exception to the hydraulic profile
requirement as we are not modifying any aspect of the facility which impacts the
hydraulics of the existing plant.)
