-- Outfall 001 Outfall 001 is the discharge point for the 7,000-acre main cooling reservoir.

This reservoir is part of the main recirculating cooling water loop used to remove heat from the steam-electric generating units.There has not been a discharge from Outfall 001 since March 1997 otherthan minor permitted leakage through the closed spillway gates and relief wells. If a discharge were to occur, blowdown from the main cooling reservoir would make up the largest percentage of wastewater.

A discharge from Outfall 001 would flow to the Colorado River (Colorado River Tidal in Segment 1401 of the Colorado River Basin).All internal outfalls (Outfalls 101, 201, 401, and 601) discharge to the main cooling reservoir.

Outfall 501 would also discharge to the reservoir via Outfall 101, but has not discharge since 1992.Low Volume Wastewater (Outfalls 101 and 201)Low volume wastewater results from water treatment operations, boiler blowdown, HVAC blowdown, floor drains, SPCC sources and their associated oily water treatment system discharges, and other miscellaneous sources. Boiler blowdown is from one auxiliary steam boiler, released to reduce impurities in the water that can cause corrosion and boiler tube failure. Service water is demineralized and regeneration of the demineralizer resin beds produces an acidic and caustic wastewater that is treated at the neutralization basins along with boiler blowdown.

The floor drain system captures condensate and water from production and maintenance areas that may contain oil or grease, which is then transported to the oily waste treatment system where the oil is separated from the water. The first flush of stormwater from some production and storage areas is also treated in the oily waste system. Other non-processstormwater flow is directed through designated stormwater outfalls.Treated Domestic Wastewater (Outfalls 401 and 601)Domestic wastewater is treated onsite in two package treatment systems consisting of aeration, clarification, and disinfection.

Car wash water, air conditioning condensate, HVAC cooling tower blowdown, and stormwater are commingled with the domestic wastewater prior to treatment.

Metal Cleaning Waste (Outfall 501)Metal cleaning waste has not been discharged since 1992. Metal cleaning using chemical or non-chemical liquids produces a waste that would be discharged through Outfall 501 to the neutralization basins (Outfall 101). Stormwater may also be discharge through Outfall 501.Main Cooling Reservoir (MCR) Relief Well Effluent (Outfolls 002-006)MCR relief well effluent is collected from the perimeter of the MCR and discharge via Outfall 002-006 without treatment.

Outfall 002 is also authorized to discharge demineralized water from Instrumentation.

STP Nuclear respectfully requests the removal of pH limitations and monitoring requirements from its internal monitoring locations.

STP feels the requirement to monitor for pH at internal monitoring locations prior to wastewater entering its own cooling reservoir is overly burdensome and has little to no positive environmental impact. In fact, due to efforts by the plant to ensure the pH limits are met, STP must chemically treat these individual wastestreams prior to sampling at the internal monitoring locations.

pH treatment would not be necessary to meet the effluent limits at the external Outfall 001 due to natural pH balancing that occurs in the cooling reservoir.

Request to remove effluent limits and monitoring requirements for relief well discharges at Outfalls 002, 003, 004, 005, and 006 and all associated permit requirements having to do with relief well monitoring.

STP requests the removal of the monitoring requirements for relief well discharges, placed in the previous TPDES permit draft. The water being discharged is predominantly groundwater that is seeping up to the surface from under the reservoir.

The water is not pumped to the surface for discharge.

STP has been conducting routine monitoring of its relief well discharges in compliance with its TPDES*permit since the permit was issued on April 5, 2012. STP has collected over two years'worth of data in that time. None of the data collected from the relief well monitoring program has exceeded an established effluent limit in the TPDES permit.
