The existing coal fired Lee Plant has two permitted outfalls to the Neuse River: Outfall 001 from the 

ash pond and Outfall 002 from the cooling pond. Upon closure of the Lee Plant, the H.F. Lee Energy 

Complex will continue to utilize the cooling pond, Outfall 002. A new outfall (003) is proposed to 

come online in 2013. Outfalls 001 and 002 are described below. No overflows, diversions, or other 

releases not otherwise allowed by the permit have occurred in the past 10 years. Allowed alternate 

flow paths are described below and in the flow diagrams provided in response to Question 7. 

Outfall 001 - Discharge from Ash Pond to Neuse River 

Ash Transport System Wastewater 

Fly ash and bottom ash from all three units are hydraulically conveyed by ash sluice pipelines to the 

Lee Plant ash pond. Included with this sluice water is some ammonia slip from operation of the 

Rotamix© system utilized for NOx air emissions control. 

Precipitator and Air Preheater Wash Water 

Water from washing the interior of the precipitators and air heaters is typically routed to the ash pond 

via the ash transport system but could be routed directly or indirectly to the cooling pond. 

Filter Plant Wastewater 

Blowdown and filter backwash wastewater generated in the filter plant is discharged into the ash sluice 

transport system which flows to the ash pond. 

Wayne County Combustion Turbine Site Wastewaters 

The containments around the accessory module, liquid fuel, and atomizing air modules and the wash 

water drain empty into collection tanks. Once there is a quantity of liquid collected in the tanks, the 

wastewater is removed by pumper truck and transported and released into the Lee Plant ash pond. The 

wash water drain tanks collect the water and detergent used to clean the CT compressors. 

Miscellaneous Wastes 

Equipment cooling tower basin sludge, circulating water tunnel sediment, and boiler vacuuming 

sediments are sent to the ash pond. Other residuals from the low volume wastes retention basin and the 

coal pile runoff retention basin and other miscellaneous low volume wastes from plant processes are 

also transported to the ash pond. Storm water from the ash line trench flows into the ash pond.

Outfall 002 – Closed Cycle Cooling Pond 

Discharges from the cooling pond are rarely made, usually only during an extremely heavy rainfall 

event or hurricane. The cooling pond last discharged in April 1994. Chemical constituents contained in 

the cooling pond discharge are, for the most part, representative of the naturally-occurring chemical 

quality and quantity of the intake water. Streams routed to the cooling pond include: 

Recirculated Condenser Cooling Water 

This flow currently provides condenser cooling water for coal-fired generating Units 1, 2, and 3. The 

total flow is recirculated into the pond and routed through the pond by baffle dikes to achieve 

maximum surface cooling efficiency before reaching the condenser cooling water intake structure to be 

used again. Cooling of the pond is achieved primarily by evaporation from the pond surface, which is 

estimated to consume approximately 3-5 MGD above natural evaporation rates during times the units 

are in full operation. 

Equipment Cooling Water (Non-contact Cooling Water) 

Circulating water for Unit 3 is withdrawn from cooling water makeup and/or the cooling pond and 

passed through two heat exchangers to provide non-contact cooling for the plant’s closed-cooling 

water system. After passing through the heat exchangers, the circulating water is routed to the cooling 

pond. Units 1 and 2 use a cooling tower for heat removal for their equipment closed-cooling water 

system. Cooling tower blowdown is routed to the low volume waste retention basin. This wastewater 

has been referred to as “service water” in the past. 

Coal Pile Runoff 

The coal pile area is surrounded by a drainage ditch that is routed to a clay-bottomed, asphalt and 

concrete-sided settling pond. The basin is sized so as to adequately store runoff and allow the 

suspended solids to settle before the supernatant is discharged by overflow to the cooling pond. 

During routine maintenance of the pond, any solids removed will be disposed of in the active ash pond. 

 

Sewage Treatment System 

Domestic waste is treated in a septic tank and sand filter bed system. Flow from the system is 

dependent upon fluctuating demand due to variations in the number of personnel on site. Residuals are 

disposed of off-site by a licensed contract disposal firm. The sand in the system is periodically changed 

to ensure system effectiveness is maintained. The spent sand is disinfected and then sent to an off-site 

landfill. 

Low Volume Wastewaters 

A low volume waste retention basin receives wastewaters from three sumps located throughout the Lee 

Plant. The sumps collect waste from floor and equipment drains, the fuel oil unloading area, boiler 

blowdown, cooling tower overflow, sampling streams, and rainfall from the immediate plant area. 

Water treatment wastes, including filter backwash and settling basin drains, are also directed to a plant 

sump. In addition, the low volume basin receives discharges from equipment washings, boiler and 

condenser drains, and closed-cooling system blowdown and drains, grey water from contractor 

washing stations, and Units 1 and 2 cooling tower blowdown. Oily waste collectors remove oil and 

grease and a holding chamber allows the solids to settle out before the effluent is discharged into the 

cooling pond. To maintain the efficiency of the basin and allow adequate freeboard, the settled sludge 

from the basin and from the three sumps will periodically be removed and disposed of in the ash pond. 

Precipitator and Air Preheater Wash Water 

Under normal operations, water from washing the interior of the precipitators and air heaters are routed 

to the ash pond via the ash transport system. However, these wastewaters could be routed directly or 

indirectly to the cooling pond in unusual situations.

(RO) water treatment system (reject water), excess evaporative cooling water, process drains, and 

stormwater from the oil water separator. Two pumps (rated at 580 gpm each), one for operation and 

one for a back up, transfer the wastewater to the Lee Plant cooling pond. The filter plant discharge 

was initiated around 2002. 

The oil water separator treats water from the containment areas around the two fuel oil storage tanks, 

the fuel forwarding pumps, and the fuel oil unloading area. Storm water collection containment areas 

around transformers and substations are examined for the presence of any oily substance; if oily 

substances are present in the containment, nothing will be drained from the containments until that 

substance is properly removed. 

Backwash water

Backwash from intake screening devices located on the Neuse River is discharged into the Neuse 

River bypass canal associated pursuant to North Carolina regulations at NCAC 15A .0106 (f)(2), if 

necessary. 

Available analytical data for hazardous constituents (as defined at 40 CFR 261, Appendix VIII) for the 

wastewater discharges are provided in the 2007 NPDES renewal applications (Appendix B) and the 

Discharge Monitoring Reports (Appendix E). No exceedances of the NPDES permit limitations have 

occurred in the previous five years. The NPDES permit no. NC0000396 is attached in Appendix F.

(10)For all stormwater discharges associated with industrial activity from the facility, as defined at 40 

C.F.R. 122.26(a)(14), identify the industrial activity (including the appropriate NAICS and SIC codes) 

that requires coverage under an NPDES permit. In addition to the information provided about these 

discharges in response to request #9, provide a copy of the facility’s current Stormwater Pollution 

Prevention Plan (“SWPPP”), as well as copies of its comprehensive site evaluations, inspection 

records, and monitoring results for the last five (5) years. If the company has not developed a SWPPP, 

provide an explanation for this decision. 

The industrial activity that conditionally requires coverage under a NPDES permit is Electric Power 

Generation, Fossil Fuel, NAICS code 221112; and Electric Power Generation by Fossil Fuels, SIC 

code 4911. 

The Lee Plant are not required under its NPDES permit to maintain a SWPPP. Stormwater discharges 

associated with industrial activities from the coal plant yards and power block is either routed to the 

cooling pond or to the ash pond. Discharges from both of these management areas are discharges 

authorized by the NPDES permit. The raw material, coal, is brought in by rail along a land corridor 

not owned by Progress Energy until the rail is on the plant site where storm water is handled as stated 

above. The access road is not used on a routine basis to ship waste products or by products off-site nor 

to receive raw materials.

(12)Describe any known spills or releases to groundwater from each management area within the last ten 

(10) years. 

No spills or releases to groundwater are known to have occurred in the last ten years from the 

management areas. Groundwater quality results from the monitoring system around the active ash 

pond (provided in question 11) show slightly elevated concentrations of some inorganic constituents. 

However, note that these results are from inside the compliance boundary as defined by the North 

Carolina 2L Groundwater Standards. Progress Energy is in the process of siting background wells and 

wells located at the compliance boundary so that an analysis can be completed to determine if a 

statistically significant release has occurred.

under the dike and also includes ground boil conditions. The seepage area has been mitigated with a 

geotextile and aggregate blanket. In 2004, seepage flow volume was estimated at 0.25-0.5 gpm from 

the geotextile and blanket area and 5 to 10 gpm from a boil area. Specific flow path of the seepage is 

not documented, but expected to flow down gradient toward the Neuse River. Piezometers are inplace at the seepage area for monitoring water levels within the slope. The location of this seepage 

condition is shown on Figure 2. 

Documentation within the last five years of the seepage flows were included in the Office of Solid 

Wastes and Emergency Response (OSWER) response letter previously provided to EPA. This

and the amount of water withdrawn in gallons per day. If applicable, describe the cooling water 

intake screen backwash system and identify the individual backwash flows, the volume, and the 

discharge points for each flow. Submit any sampling results of the backwash. 

Approximately 372 MGD of cooling water is used from the cooling pond. Water is collected from the 

pond through the plant intake structure and routed to the condensers then back to the pond, or to the 

water treatment system for use in plant processes. 

Make-up water from the Neuse River is routed to the cooling pond and the closed cycle cooling system 

for Unit 3, if needed (approximately 12.7 MGD). The intake from the Neuse River passes through a 

bar screen which does not typically require backwashing. However, backwash from intake screening 

devices is allowed to be discharged into the Neuse River bypass canal associated with the Neuse River 

pursuant to North Carolina regulations at NCAC 15A 02H.0106 (f)(2), should backwashing be 

necessary. No data is available on the quantity of backwash flows or on its chemical characteristics.
