This letter is intended to inform you of planned activities at the Marshall Hydroelectric Plant. These
activities have been discussed between Ms. Wanda Frazier of your staff and Mr. Ricky Miller of CP&L.
As you are aware the Marshall Plant's NPDES Permit has an outfall identified as 001. Outfall 001
collects stormwater and wastewater from different locations at the Marshall Plant. The wastewater
consists of water collected from various seals and packing where river water enters the plant.
It is CP&L's intention to take the water collected in this system and evaporate it. Outfall 001 will still be
retained as a discharge point and any discharge will be monitored, as required by the permit. It should be
noted that this system has not discharged in over a year. Enclosed for your information is a pamphlet that
describes the equipment for the planned installation.
By evaporating the water in the system and carefully monitoring the system, it will lessen the chance of
any pollutant entering the river. If you have any questions concerning the planned installation please call
Mr. R. K. Miller at [phone].
Sincerely,
Larry

3. Additional effluent limits requests: none
4. Other: n/a
PART IV - EVALUATION AND RECOMMENDATIONS
1. Carolina Power and Light Company has requested renewal of
NPDES Permit No. NC00027545 for the Marshall Hydroelectric
Plant. The wastewater consists of the following discharges:
001 - Oil and Water Separator - A sump and pump are located
on the bottom floor of the powerhouse and collect water and
oil from the turbine area and switch yard area. The oil and
water are pumped to ground level to an oil and water
separator and oil storage tank. The discharge is to the
French Broad River. Since this system rarely discharges, an
alarm device was installed to allow the operator to know
when there is a discharge, so samples can be collected.
002 - Draft Tube Drain Pumps - The draft tube drain pumps
dewater the draft tube extension below the wicket gates,
when work is to be performed in that area. These pumps are
only operated during maintenance activities and pump water
from the draft tubes into the tail race area.
003 - Cooling Water Drains - The two cooling water drains
discharge river water from the lube oil unit and speed
increaser oil coolers into the tailrace area. The cooling
water system operates on a continuous basis with a maximum
flow of approximately 75 gpm through each drain when each
unit is operating.
2. Note: I recommend the removal of the following statement
in the 003 limits page of the current permit. "The pH shall
not be less than 6.0 standard units nor greater thatn 9.0
standard units." The pH of the river water used to cooling
cannot be controlled by the permittee. This river water is
"passed through" these areas only once.
-3-

3. The facility can comply with existing NPDES Permit limits.
It is recommended that permit number NC0027545 be renewed.

• Cooling Water is withdrawn from the penstock and used to cool machinery and
lubricating oil in the plant by use of heat exchangers (non -contact cooling). There
is one discharge for each of the two generating units.
Although the cooling water discharged is warmer than ambient water temperature,
the impact on the French Broad River is negligible due to low discharge flow and
temperature differential. The cooling water flows, which are less than one-half cubic
foot per second (cfs) are insignificant compared to the flow of the river, which
averages approximately 2500 cfs at the plant. Previous monitoring of temperature
has demonstrated that the heat input to the river does not result in a violation of
water quality thermal standards.
• Water from floor drains and oil contaminated water from the switchyard area catch
basin area are routed through an oil/water separator prior to discharge to the river.
• Water from the draft tube extension area is essentially only river water that is
pumped out to dewater the turbine area for infrequent maintenance or repairs.
Turbine shaft seal leakage is also discharged at this location.
• A small quantity of intake filter backwash water is discharged to the river.

Carolina Power & Light Company (CP&L) has reviewed the draft of the referenced
permit that was public noticed on March 25, 1987. The present permit was
substantially revised in October, 1985, at the Company's request due to a
major renovation and installation of new machinery. At that time, CP&L
requested that, because of the extremely small quantity of heat added,
temperature monitoring not be required for outfall 003, Non -contact Cooling
Water. DEM staff, however, felt that at least 6 months of actual monitoring
would be necessary to demonstrate the validity of CP&L calculations provided
in a letter to DEM dated September 16, 1985 (Serial No. ESS-85-1239), which
indicated any temperature increase would be negligable.
Enclosed is a table of temperature measurements made from August, 1986,
through March, 1987. Before August, 1986, the plant operated very little due
to mechanical difficulties. Included in the table are gross generation values
for each unit, the difference in upstream and downstream measured temperatures
( 6 T), and the average river flow for the day of sampling. The water
discharged at outfall 003 is used to cool lubricating oil for the
hydroelectric machinery at the plant. The amount of heat produced is
proportional to the quantity of electricity generated and is, therefore, also
proportional to the river flow. As a result, larger discharges of heated
water would generally have correspondingly larger river flows available for
dilution.
The river flows presented range from a low of 548 cfs (7Q 0 = 530 cfs) to an
excess of the approximately 2600 cfs maximum usable flow for the hydroelectric
turbines. The electrical generation for these days, and therefore waste heat
generated, is indicative of what would be experienced at these flows. As can
be seen, the individual a T's are no more than 0.6oF, (often less than zero)
and these are probably due to the normal flunctuation one would expect in grab
samples in a turbulent river. The average Q T is essentially zero, as
predicted in the calculations supplied earlier.

Comments and Recommendations
Request from Carolina Power and Light Company to
Modify Draft NPDES Permit Number NC0027545
Marshall Hydroelectrid Plant
Madison County, North Carolina
Carolina Power and Light Company has requested that the draft
NPDES Permit be modified to require no monitoring of flow and
temperature from discharge 003 from the Marshall Hydroelectric Plant.
Discharge 003 consist two cooling water discharges from the lube
oil unit and speed increaser coolers in the tailrace area. The cooling
water system operates on a continuous basis with a maximum flow of
approximately 75 gpm through each drain when the units are functioning.
Based on the monitoring data supplied by Carolina Power and Light
Company and the volume of wastewater from discharge 003 this office
would recommend that the monitoring requirements for flow and
temperature (discharge 003) be removed from draft permit number
NC0027545.
