Page 47 Outfall 004 A. Type of wastewater - the intermittent discharge from the plant drainage ditch system to 40 Arpent Canal. Outfall 004 is a new
outfall that consolidates Outfalls 04A and 04B from former NPDES
Permit LA0007374. Most of the effluent monitored at this outfall
is 85% stormwater runoff. Besides stormwater, potable water from
the fire water system, maintenance wastewaters including, but not
limited to: hydrostatic test water, air conditioning condensate, low volume wastewaters from various sources as defined in 40 CFR
423, and previously monitored effluents exit the facility via
Outfall 004. Low volume sources contributing wastewater to this
outfall include, but are not limited to, reverse osmosis reject
water and demineralized water. The plant drainage ditch system
receives treated discharge from the yard oil separator system (Internal Outfall 104), untreated vehicle wash wastewater (Internal Outfall 204), and during maintenance activities
discharges from Dry Cooling Tower Sump #1 (Internal Outfall 701)
and Dry Cooling Tower Sump #2 (Internal Outfall 801).
B. Location - at the point of discharge from the plant drainage ditch system where the plant stormwater runoff, the previously monitored
effluents, and other infrequently discharged low volume
wastewaters discharge at Latitude 2959'19", Longitude 9028'25" prior to entering 40 Arpent Canal.

Page 68 IX. Permit Limit Rationale:
The following section sets forth the principal facts and the significant
factual, legal, methodological, and policy questions considered in preparing
the draft permit. Also set forth are any calculations or other explanations
of the derivation of specific effluent limitations and conditions, including a
citation to the applicable effluent limitation guideline or performance
standard provisions as required under LAC 33:IX.2361/40 CFR Part 122.44 and
reasons why they are applicable or an explanation of how the alternate
effluent limitations were developed.
A. TECHNOLOGY-BASED VERSUS WATER QUALITY STANDARDS-BASED EFFLUENT LIMITATIONS AND CONDITIONS
Following regulations promulgated at LAC 33:IX.2361.L.2.b/40 CFR Part
122.44(l)(2)(ii), the draft permit limits are based on either technology-based
effluent limits pursuant to LAC 33:IX.2361.A/40 CFR Part 122.44(a) or on State
water quality standards and requirements pursuant to LAC 33:IX.2361.D/40 CFR
Part 122.44(d), whichever are more stringent.
B. TECHNOLOGY-BASED EFFLUENT LIMITATIONS AND CONDITIONS
Regulations promulgated at LAC 33:IX.2361.A/40 CFR Part 122.44(a) require
technology-based effluent limitations to be placed in LPDES permits based on
effluent limitations guidelines where applicable, on best professional
judgement (BPJ) in the absence of guidelines, or on a combination of the two.
The permittee is subject to Best Practicable Control Technology Currently
Available (BPT) and Best Available Technology Economically Achievable (BAT)
effluent limitation guidelines listed below:
Manufacturing Operation Guideline Steam Electric Power Generating Point Source Category 40 CFR 423
Outfall 001
This outfall is the continuous discharge from the turbine condenser cooling
system to the Mississippi River. The turbine condenser cooling system
receives once-through non-contact cooling water from the Mississippi River
that flows through the main condenser, the steam generator blowdown heat
exchangers, and the turbine building closed cooling heat exchanger.
Previously monitored discharges from Internal Outfalls 101 (former 01A), 201 (former 01B), 301 (former 01C), 401 (former 01D), 501, 601, 701, 801, and 901
also are discharged via Outfall 001. The combined flow volume of these
intermittent internal outfalls (estimated at 1.65 MGD) is significantly less
than the maximum 30 day average flow of the once-through non-contact cooling
water through Outfall 001 (1,346 MGD). The effluent limitations proposed for
Outfall 001 in the draft LPDES permit are as follows:
Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 69 Parameter Monthly Daily Average Maximum Flow Report 1,518 MGD Temperature (F) Report 118F Heat N/A 9.5 x 10 9 BTU/Hour Boron N/A 0.2 mg/l Total Residual Chlorine N/A 211 lbs/day
Flow
The flow limitation of 1,518 MGD for daily maximum at Outfall 001 is retained
from the current NPDES permit. This maximum daily flow limit was requested by
Louisiana Power and Light Company (LP&L, predecessor to Entergy) in a letter
to EPA Region 6 dated March 1, 1985. This letter requested an increase in the
daily maximum flow of the once-through non-contact cooling water from the
limit of 1,445 MGD then in effect to 1,518 MGD which LP&L described as the "maximum hydraulic capability" of the turbine condenser cooling system. This
request was granted in a letter from EPA Region 6 to LP&L dated May 30, 1985.
Discharge flow is to be determined from calibrated pumping curves or
calculated using appropriate heat balance methodology.
Boron The current NPDES permit established a calculated daily maximum discharge
limit of 0.2 mg/l for boron at Outfall 001. The fact sheet for this NPDES
permit stated this boron limitation was based on BPJ since boron is for
reactivity control in the reactor. The limit is retained on the same basis.
Total Residual Chlorine
The current NPDES permit established daily maximum discharge limits of 211
lbs/day and 0.2 mg/l for total residual chlorine (TRC) at Outfall 001. The
limit is based on 40 CFR 423.13(b)(1)(BAT). Since the discharge from Outfall
001 is continuous and not significantly variable, only the mass limitation is
continued.
Site-Specific Consideration Temperature and Heat
In an application addendum submitted June 15, 1998, the permittee requested that the temperature and heat discharge limits included in the current NPDES permit, 110F and 8.5 x 10 9 BTU/Hour, be increased to 118 F and 9.5 x 10 9 BTU/Hour, respectively, or removed from the new permit entirely.
Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 70 The permittee bases the request for an increase in temperature and heat discharge limits on a planned "power uprate" to be implemented in the near future at Waterford 3. On August 26, 1996, this Office issued a letter of no objection to the permittee's request for a power uprate. However, the permit limitations and conditions in the current permit were not adjusted to accommodate a power uprate and compliance with those limitations was still required. Current limits can not be met with a production increase, especially during months when customer demand for electricity is high. This increase in the megawatt output of the facility will result in more waste heat that will need to be transferred from the turbine condenser to the once-through non-contact cooling water. Because the turbine condenser cooling system will continue to operate within its current hydraulic capability, the removal of this additional waste heat will result in higher discharge temperatures for the once-through non-contact cooling water.
Due to the Nuclear Regulatory Commission (NRC) approved design of the plant itself, full power operation, following a power uprate, would result in an increase in temperature and heat discharged in once-through non-contact cooling water. The following is an explanation of how this occurs.
Thermal energy is generated from the nuclear fuel inside a reactor.
Reactor coolant is circulated inside the reactor coolant system to carry that thermal energy to the secondary coolant via a non-contact steam generator. Steam produced from the steam generator drives the turbine-generator producing electricity. Exhaust steam from the outlet of the turbine is condensed by the non-contact cooling water in the circulating water system. Approximately one-third of the heat produced by the reactor is absorbed by the non-contact cooling water in the circulating water system which discharges through Outfall 001 to the Mississippi River. Therefore to increase the electrical output, the thermal energy produced by the reactor must increase proportionally to the increase of electricity. As a result of the increase in reactor thermal power, more heat is absorbed by the non-contact cooling water in the circulating water system.
Both the temperature and heat limitations included in the current permit are technology-based limitations. 40 CFR 423 promulgated as commanded by Section 304 of the Clean Water Act did not establish temperature or heat limitations.
Therefore, best professional judgment (BPJ) was used by EPA, Region VI, to establish the Best Available Technology (BAT), economically achievable, for the current temperature and heat limitations contained in the NPDES permit.
The heat limit currently in effect, 8.5 x 10 9 BTU/Hour, resulted from the Demonstration under Section 316(a) of the Clean Water Act submitted by LP&L in April 1979. On page 35 of this document, LP&L requested that EPA establish 8.5 x 10 9 BTU/Hour as an alternative thermal limitation for Waterford 3. An internal EPA Region 6 memo dated August 24, 1979 discussed the EPA review of this 316(a) demonstration. In this memo, the EPA reviewer concurred with LP&L's conclusion that the alternative thermal limitation "adequately Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 71 regulates the amount of heat discharged to the Mississippi River from this facility such that it protects the balanced indigenous population". However, the EPA reviewer continued "although the demonstration requests no maximum thermal limitation be placed in the permit, I recommend an instantaneous thermal maximum of 110 F be placed in the permit to further insure protection of the aquatic species". The 110 F stems from a maximum instantaneous heat discharge of 8.5 x 10 9 BTU/Hour, an instantaneous flow rate of 1,000 MGD for the once-through non-contact cooling water, and a typical maximum stream temperature of 86 F. The definition of a British thermal unit (BTU) is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit at or near 39.2F. Ignoring the slight variation in thermal conductivity of water due to its ambient temperature, the temperature increase of the cooling water conveying the waste heat from the turbine condenser can be estimated by dividing the waste heat in BTU/hour by the cooling water flow in pounds per hour (lbs/hour).
The conversion of the cooling water flow from MGD to lbs/hour is accomplished as follows:
[(1,000 x 10 6 gal/day) x (8.337 lbs/gal)] [24 hr/day] = 347,375,000 lbs/hour Dividing the alternative heat limit by the converted cooling water flow yields:
(8.5 x 10 9 BTU/Hour) (347,375,000 lbs/hour) = 24.5F Adding this to the typical maximum stream temperature produces the following discharge temperature:
86F + 24.5F = 110.5F or approximately 110F Applying the same methodology for a heat limit of 9.5 x 10 9 BTU/Hour and a maximum fresh water stream temperature of 90F (specified in LAC 33:IX.1113.C.4) produces a discharge temperature of approximately 118F. Using a flow of 1,000 MGD in these calculations is reasonable because the long term average flow for Outfall 001 is 1,085 MGD according to the permit application.
To further ensure attainment of LAC 33:IX.1113.C.4.b.i.(a), the 5F allowable rise of temperature above ambient was applied at the edge of the mixing zone.
Appendix A illustrates that a violation of the above citation would not occur with a discharge limitation for temperature at 118F. The Demonstration under Section 316(a) of the Clean Water Act classified the Mississippi River near Waterford 3 as "an area of low potential impact for Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 72 thermal discharges". This classification resulted from: (1) the determination that this stretch of the Mississippi River was not "unique" for any shellfish, fish, or wildlife; and (2) the realization that most of the cross-sectional area available for flow in the river would be unaffected by the thermal plume.
Therefore, the indigenous population of shellfish, fish, and wildlife, which are present in abundance in areas away from Waterford 3, either would have ample opportunity to pass by the facility without encountering elevated stream temperatures or would only experience the higher temperatures for such brief periods that no deleterious effects would result.
The 316(a) demonstration found that no threatened or endangered species were present near Waterford 3. The species that were present also were abundant in other areas of the Mississippi River. The study also determined that no special fish spawning habitat existed near the facility.
The 316(a) demonstration documented thermal model results for various flow and temperature conditions reflecting seasonal variations in this stretch of the Mississippi River. The models accounted for the historically calibrated thermal discharges for the nearby Waterford 1 and 2 and Little Gypsy steam electric generating plants, as well as for the 8.5 x 10 9 BTU/Hour anticipated for Waterford 3. A worst case scenario of an extreme low flow of 100,000 cubic feet per second (cfs) was modeled in the study. This minimum flow in the lower Mississippi River is maintained by the Old River Control Structure operated by the U.S. Army Corps of Engineers and is less than the 7Q10 flow for this segment of the river (141,955 cfs). Under this worst case, extreme low flow situation, the model determined that less than 15% of the cross-sectional area of the river would experience temperature increases of 5 F. This thermal plume also stayed near the surface of the river extending no deeper than 10 feet.
In the Final Environmental Statement Related to the Operation of Waterford Steam Electric Station, Unit No. 3 , the Nuclear Regulatory Commission (NRC) documented model studies conducted by their staff to independently confirm the results presented by LP&L in the 316(a) demonstration. Using a different model, the NRC produced results that were "generally in agreement" with those presented by LP&L. The NRC model produced a slightly larger combined thermal plume or mixing zone, but the environmental statement concluded that operation of Waterford 3 would be "in compliance with the Louisiana Water Quality Criteria relating to temperature". With all three plants operating at peak loads during extreme low flow conditions, an adequate zone of passage (83% of the river cross-sectional area) will still remain for aquatic species to pass by facilities without entering the combined thermal mixing zone. Species entering the mixing zone probably would pass through it in one hour or less, minimizing the impact of the elevated temperatures. Also natural ambient river surface temperatures above 86 F should only occur about 2.5% of the time. Applying the percentage increase of thermal discharge at Waterford 3 to the model worst case, extreme low flow thermal plume should provide a conservative Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 73 estimate of the combined thermal mixing zone that would result from the planned power uprate. This should be very conservative due to Waterford 3 contributing less heat to the river than Waterford 1 and 2 and Little Gypsy combined. Increasing the heat discharge to 9.5 x 10 9 BTU/Hour from 8.5 x 10 9 BTU/Hour constitutes a 12% gain. Applying this proportional gain to the worst case combined thermal plume (17% of river cross-sectional area) yields an anticipated combined thermal mixing zone of 19%. This leaves approximately 81% of the river flow unaffected by the temperature increase after the Waterford 3 power uprate, even under extreme low flow conditions.
LAC 33:IX.1115.C.7 specifies the mixing zone for streams with 7Q10 flow greater than 100 cfs as either 100 cfs or 1/3 of the flow, whichever is greater. The anticipated thermal mixing zone of 19% is substantially less than 33% of cross-sectional area or 1/3 of the flow. Therefore, the increased heat discharge and temperature limits requested for Outfall 001 are expected to meet Louisiana Water Quality Criteria for temperature.
In response to this Office's concern expressed in the August 26, 1996 letter, the combined thermal discharges from Waterford 1 and 2, Waterford 3, and Little Gypsy were evaluated in respect to the cooling tower operations of a downstream facility, Union Carbide. This facility is 1.6 river miles down from Waterford 3. In 1971, the U.S. Department of Interior, Geological Survey in cooperation with Louisiana Department of Public Works, prepared Hydrologic and Quality Characteristics of the Lower Mississippi River, Technical Report Number 5. The purpose of the report was to further an understanding of the hydrologic and quality characteristics of the lower Mississippi River, including the effects of industrial development on water quality and the ability of the river to assimilate wastes. In evaluating the effects of heated effluent, the report states "Very little vertical mixing occurred because the heated water was less dense and floated on the surface."
Because the heated water is less dense than the cooler ambient river water, the combined thermal mixing zone remains near the surface. As mentioned earlier, the worst case thermal plume extends no more than about 10 feet deep.
Since the intake structure for Union Carbide is 3 feet below mean sea level, no rise in temperature above ambient would be detected. Additionally, Union Carbide's cooling water enters the facility via an internal canal. This canal would effectively return river water to ambient temperature prior to entering the facility's cooling system.
Technology to achieve the current limitations for temperature and heat does exist through the use of cooling towers. However, that technology is not economically achievable for Waterford 3. This facility is regulated by the NRC and any change in the operation or equipment must be approved by that agency. For the relatively small increase in temperature and heat caused by the power uprate, modifying the plant itself is not economically justified.
In conclusion, this permit proposes to increase the temperature to 118F and heat to 9.5 x 10 9 BTU/hour as requested by the permittee.

Page 74 Internal Outfalls
In accordance with 40 CFR 122.56(b)(1)(ii), the following is an explanation
for the establishment of Internal Outfalls 101, 201, 301, 401, 501, 601, 701, 801, 901, 104, and 204. Certain permit effluent limitations at the point of
discharge are impractical because at the final discharge point the wastes at
the point discharge are so diluted as to make monitoring impracticable. pH
must be monitored internally at the outfalls internal to Outfall 001 because
the design of the plant does not allow for the measurement to be taken prior
to entering the Mississippi River. Therefore, in accordance with 40 CFR
122.46(h)(2) the internal outfalls described below are established.
Internal Outfall 101 (Former 01A) - Liquid Waste Management System
This outfall is the intermittent internal discharge from the liquid waste
management system to Final Outfall 001 via the turbine condenser cooling
system. The liquid waste management system receives low volume wastewater
from the following sources, including but not limited to: the turbine and
reactor building equipment and floor drains, primary plant water makeup, laboratory drains, and other low volume wastewater sources as defined in 40
CFR 423. The effluent limitations proposed for Outfall 101 in the draft LPDES
permit are as follows:
Parameter Monthly Daily Average Maximum mg/L mg/L Flow, MGD N/A Report Total Suspended Solids N/A 100 Oil and Grease N/A 20 Boron N/A Report pH, standard units 6.0 (min) 9.0 (max)
Flow
The permittee has requested to change the daily average flow limitation from
0.0288 MGD to Report. The daily average flow limitation of 0.0288 MGD at
Internal Outfall 101 (former 01A) is in the current NPDES permit. This
average daily flow limit was requested by LP&L in a letter to EPA Region 6
dated March 1, 1985. This letter requested an increase in the daily average
flow of the liquid waste management system from the limit of 0.0093 MGD then
in effect to 0.0288 MGD which LP&L described as necessary "to accommodate
efficient operation of the plant". This request was granted in a letter from
EPA Region 6 to LP&L dated May 30, 1985.
The permittee contends that this flow limit at Internal Outfall 101
unnecessarily restricts plant operations without adding to the quality of the
discharges from the facility. Because discharges from the liquid waste
management system occur in batches and each batch requires monitoring prior to Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 75 discharge, all the effluent conveyed past Internal Outfall 101 meets the
discharge criteria specified in the permit, regardless of flow quantity.
Given that a power uprate at Waterford 3 will require additional operation of
the liquid waste management system to support the increased generation of
electricity, the permittee's request to remove the daily average flow limit of
0.0288 MGD is granted. Discharge flow is totalized when the discharge occurs.
Total Suspended Solids
The current NPDES permit established a daily average discharge limit of 30
mg/l and a daily maximum discharge limit of 100 mg/l for total suspended
solids at Internal Outfall 101 (former 01A). Since the flow to this outfall
is intermittent only the daily maximum limitation is continued from the
current permit. This limit is based on 40 CFR 423.12(b)(3)(BPT).
Oil and Grease
The current NPDES permit established a daily average discharge limit of 15
mg/l and a daily maximum discharge limit of 20 mg/l for oil and grease at
Internal Outfall 101 (former 01A). Since the flow to this outfall is
intermittent only the daily maximum limitation is continued from the current
permit. This limit is based on 40 CFR 423.12(b)(3)(BPT).
The current NPDES permit established Report for both the daily average
discharge limit and daily maximum discharge limit for boron at Internal
Outfall 101 (former 01A). Since the flow to this outfall is intermittent only
the daily maximum reporting requirement is continued from the current permit.
This requirement is based on the current permit.
pH
The current NPDES permit established a minimum discharge limit of 6.0 standard
units and a maximum discharge limit of 9.0 standard units for pH at Outfall
101 (former 01A). These limits are based on 40 CFR 423.12(b)(1)(BPT) and are
retained from the current permit.
Internal Outfall 201 (Former 01B) - Boron Management System
This outfall is the intermittent internal discharge from the boron management
system to Final Outfall 001 via the turbine condenser cooling system. The
boron management system concentrates and recovers boron from low volume
wastewaters for reuse within the plant. The boron management system receives
low volume wastewater from the following sources, including but not limited
to: the turbine and reactor building equipment and floor drains, primary
plant water makeup, laboratory drains, and other low volume wastewater sources Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 76 as defined in 40 CFR 423. The effluent limitations proposed for Internal
Outfall 201 in the draft LPDES permit are as follows:
Parameter Monthly Daily Average Maximum mg/L mg/L Flow, MGD N/A Report Total Suspended Solids N/A 100 Oil and Grease N/A 20 Boron N/A Report pH, standard units 6.0 (min) 9.0 (max)
Flow
The permittee has requested to change the daily average flow limitation from
0.0288 MGD to Report. The daily average flow limitation of 0.0288 MGD at
Internal Outfall 201 (former 01B) is included in the current NPDES permit.
This average daily flow limit was requested by LP&L in a letter to EPA Region
6 dated March 1, 1985. This letter requested an increase in the daily average
flow of the boron management system from the limit of 0.0144 MGD then in
effect to 0.0288 MGD which LP&L described as necessary "to accommodate
efficient operation of the plant". This request was granted in a letter from
EPA Region 6 to LP&L dated May 30, 1985.
The permittee contends that this flow limit at Internal Outfall 201
unnecessarily restricts plant operations without adding to the quality of the
discharges from the facility. Because discharges from the boron management
system occur in batches and each batch requires monitoring prior to discharge, all the effluent conveyed past Internal Outfall 201 meets the discharge
criteria specified in the permit, regardless of flow quantity.
Given that a power uprate at Waterford 3 will require additional operation of
the boron management system to support the increased generation of
electricity, the permitee's request to remove the daily average flow limit of
0.0288 MGD is granted. Discharge flow is totalized when the discharge occurs.
Total Suspended Solids
The current NPDES permit established a daily average discharge limit of 30
mg/l and a daily maximum discharge limit of 100 mg/l for total suspended
solids at Internal Outfall 201 (former 01B). Since the flow to this outfall
is intermittent only the daily maximum limitation is continued from the
current permit. This limit is based on 40 CFR 423.12(b)(3)(BPT).
Oil and Grease

condenser cooling system. The primary water treatment system filters river
water for various plant uses. The filters of this system are flushed
periodically with untreated river water to remove solids trapped in the filter
beds. The effluent limitations proposed for Internal Outfall 301 in the draft
LPDES permit are as follows:
Parameter Monthly Daily Average Maximum Flow, MGD N/A Report
Clarifying Agents Used
Flow
The current NPDES permit required the daily average flow and daily maximum
flow to be reported at Internal Outfall 301 (former 01C). Since the flow to
this outfall is intermittent, the daily maximum flow is to be reported.
Discharge flow is totalized when the discharge occurs.
Clarifying Agents Used
The current NPDES permit specified the recording of the monthly amount of
clarifying agents used at Internal Outfall 301 (former 01C). This requirement
is continued from the current permit. However, no reporting on Discharge
Monitoring Reports (DMRs) will be required. The permittee is required to keep
these monthly records onsite, available to DEQ or EPA anytime or upon request.
The draft permit establishes a permit requirement for the onsite maintenance
of this information in Part I.

The following pollutants received water quality based effluent limits:
None Minimum quantification levels (MQL's) for state water quality numerical
standards-based effluent limitations are set at the values listed in the Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 90 Permitting Guidance Document for Implementing Louisiana Surface Water Quality Standards , LDEQ, October 30, 1995. They are also listed in Part II of the permit.
The nearest drinking water intake, St. Charles Parish Number 2, is located on
the east bank at 125.1 M.A.H.P., 4.4 miles downstream from the discharge
point. According to a fax received on 9/26/96 from Leslie Lemon of the
Department of Health and Hospitals, Office of Public Health, there have been
no toxic exceedences of drinking water Maximum Contaminant Levels at this
drinking water intake. Nearby potable water industrial intakes include Union
Carbide Corporation.
D. Biomonitoring Requirements
It has been determined that there may be pollutants present in the effluent
which may have the potential to cause toxic conditions in the receiving
stream. The State of Louisiana has established a narrative criteria which
states, "toxic substances shall not be present in quantities that alone or in
combination will be toxic to plant or animal life." The Office of Water
Resources requires the use of the most recent EPA biomonitoring protocols.
Whole effluent biomonitoring is the most direct measure of potential toxicity
which incorporates both the effects of synergism of effluent components and
receiving stream water quality characteristics. Biomonitoring of the effluent
is, therefore, required as a condition of this permit to assess potential
toxicity. See Appendix C for the permittee's biomonitoring history and
biomonitoring frequency recommendation. The biomonitoring procedures
stipulated as a condition of this permit for Outfall 001 are as follows:
TOXICITY TESTS FREQUENCY Acute static renewal 48-hour once per year
definitive toxicity test
using Daphnia pulex Acute static renewal 48-hour once per year
definitive toxicity test
using fathead minnow (Pimephales promelas)
Toxicity tests shall be performed in accordance with protocols described in
the latest revision of the "Methods for Measuring the Acute Toxicity of
Effluents and Receiving Waters to Freshwater and Marine Organisms." The
stipulated test species are appropriate to measure the toxicity of the
effluent consistent with the requirements of the State water quality
standards. The biomonitoring frequency has been established to reflect the
likelihood of ambient toxicity and to provide data representative of the toxic
potential of the facility's discharge in accordance with regulations
promulgated at LAC 33:IX.2369/40 CFR Part 122.48.
Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 91 Results of all dilutions as well as the associated chemical monitoring of pH, temperature, hardness, dissolved oxygen, conductivity, and alkalinity shall be
documented in a full report according to the test method publication mentioned
in the previous paragraph. The permittee shall submit a copy of the first
full report to this Office. The full report and subsequent reports are to be
retained for three (3) years following the provisions of Part III.C.3 of this
permit. The permit requires the submission of certain toxicity testing
information as an attachment to the Discharge Monitoring Report.
This permit may be reopened to require effluent limits, additional testing, and/or other appropriate actions to address toxicity if biomonitoring data
show actual or potential ambient toxicity to be the result of the permittee's
discharge to the receiving stream or water body. Modification or revocation
of the permit is subject to the provisions of LAC 33:IX.2407/40 CFR 124.5.
Accelerated or intensified toxicity testing may be required in accordance with
Section 308 of the Clean Water Act.
Dilution Series
The permit requires five (5) dilutions in addition to the control (0%
effluent) to be used in the toxicity tests. These additional effluent
concentrations shall be 56%, 42%, 32%, 24%, and 18%. The low-flow effluent
concentration (critical dilution) is defined as 42% effluent.
E. MONITORING FREQUENCIES
Regulations require permits to establish monitoring requirements to yield data
representative of the monitored activity [LAC 33:IX.2369/40 CFR 122.48(b)] and
to assure compliance with permit limitations [LAC 33:IX.2361.I./40 CFR
122.44(I)]. The following section(s) explain the rationale for the monitoring
frequencies stated in the draft permit. See outfall information for associated
outfalls concerning the type of wastewaters in Section VII.
Outfall 001
Monitoring frequencies for all effluent characteristics, except the
biomonitoring which was discussed above in Section IX.D, are retained from the
current permit. Flow, Temperature (F), and Heat (BTU/hour) are continuous with a sample type of record. Boron is calculated daily. Total Residual
Chlorine is measured once per week by grab sample, during periods of
chlorination.
Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 92 Internal Outfall 101 (Former 01A) - Liquid Waste Management System
Monitoring frequencies for all effluent characteristics are retained from the
current permit. Flow, TSS, Oil and Grease, Boron, and pH are once per batch.
Flow is totalized by a flow meter not estimated as the current permit states.
Therefore this permit proposes to change the sample type for flow to
totalized. Sampling for TSS, Oil and Grease, Boron, and pH are by grab
sampling.
Internal Outfall 201 (Former 01B) - Boron Management System
Monitoring frequencies for all effluent characteristics are retained from the
current permit. Flow, TSS, Oil and Grease, Boron, and pH are once per batch.
Flow is totalized by a flow meter not estimated as the current permit states.
Therefore this permit proposes to change the sample type for flow to
totalized. Sampling for TSS, Oil and Grease, Boron, and pH are by grab
sampling.
Internal Outfall 301 (Former 01C) - Filter Flush System
Flow is totalized weekly by a flow meter not estimated as the current permit
states. Therefore this permit proposes to change the sample type for flow to
totalized. The monthly recording based on an inventory calculation of the
clarifying agents used is retained from the current permit. However, no DMR
reporting is required. This permit proposes a requirement for the permittee
to maintain these records onsite.
Internal Outfall 401 (Former 01D) - Low Volume Wastewaters
The measurement frequency and sample type for flow, TSS, Oil and Grease, and
pH are retained from the current permit. Flow is daily by a totalized sample
type. TSS, Oil and Grease, and pH are by a grab sample.
Internal Outfall 501 - Auxiliary Component Cooling Water Basin A
This permit proposes a monitoring frequency of once per week for all
parameters, when discharging. The sample type for flow is estimate and the
sample type for TOC, TSS, Oil and Grease, and pH are by a grab sample.
During circulating water flow testing, sampling for TSS is not required (when
Mississippi River water is used for the flow test).
Internal Outfall 601 - Auxiliary Component Cooling Water Basin B
This permit proposes a monitoring frequency of once per week for all
parameters, when discharging. The sample type for flow is estimate and the
sample type for TOC, TSS, Oil and Grease, and pH are by a grab sample.

LA0007374
Page 93 During circulating water flow testing, sampling for TSS is not required (when
Mississippi River water is used for the flow test).
Internal Outfall 701 - Dry Cooling Tower Sump #1
This outfall is comprised of greater than 85% stormwater, therefore this
permit proposes a monitoring frequency of once per month for all parameters, when discharging. The sample type for flow is estimate and the sample type
for TOC, TSS, Oil and Grease, Free Available Chlorine, Total Chromium, Total
Zinc, and pH are by a grab sample. Free Available Chlorine, Total Chromium, and Total Zinc are analyzed when the discharge includes cooling tower
blowdown.
Internal Outfall 801 - Dry Cooling Tower Sump #2
This outfall is comprised of greater than 85% stormwater, therefore this
permit proposes a monitoring frequency of once per month for all parameters, when discharging. The sample type for flow is estimate and the sample type for
TOC, TSS, Oil and Grease, Free Available Chlorine, Total Chromium, Total Zinc, and pH are by a grab sample. Free Available Chlorine, Total Chromium, and
Total Zinc are analyzed when the discharge includes cooling tower blowdown.
Internal Outfall 901 - Metal Cleaning Wastewater
This permit proposes a monitoring frequency of once per week for all
parameters, when discharging. The sample type for flow is estimate and the
sample type for TSS, Oil and Grease, Total Copper, Total Iron, and pH are by a
Outfall 004 - Stormwater
This permit proposes a monitoring frequency for all parameters of once per
quarter, when discharging. The sample type for flow is estimate and the
sample type for TOC, Oil and Grease, TSS, and pH are by a grab sample.
Internal Outfall 104 - Yard Oil Separator
This permit proposes a monitoring frequency of once per month for all
parameters, when discharging. The sample type for flow is estimate and the
sample type for TSS, Oil and Grease, and pH is by a grab sample.
Internal Outfall 204 - Vehicle Wash Wastewater
The monitoring frequency of vehicle wash wastewater follows LDEQ's vehicle
wash wastewater general permit. The monitoring frequency is once per quarter
for all parameters, when discharging. The sample type for flow is estimate
and the sample type for COD, TSS, Oil and Grease, pH, and soaps and/or
detergents is by grab sample.
Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
LA0007374
Page 94 Outfall 005 - Energy Education Center Sewage Treatment Plant
All parameters will be monitored once per six months based on monitoring
frequencies established for similar discharges. The sample type for flow is
estimate and the sample type for BOD 5 , TSS, Fecal Coliform, and pH is by a grab sample.
X. Endangered Species:
The receiving waterbody, Subsegment 070301 of the Mississippi River Basin is
not listed in Section II.2 of the Implementation Strategy as requiring
consultation with the U.S. Fish and Wildlife Service (FWS). This strategy was
submitted with a letter dated September 26, 1997 from Fruge (FWS) to Aydell (LDEQ). Therefore, in accordance with the Memorandum of Understanding between
the LDEQ and the FWS, no further informal (Section 7, Endangered Species Act)
consultation is required. It was determined that the issuance of the LPDES
permit is not likely to have an adverse effect on any endangered or candidate
species or the critical habitat. The effluent limitations established in the
permit ensure protection of aquatic life and maintenance of the receiving
water as aquatic habitat.
XI. Historic Sites:
The discharge is from an existing facility location, which does not include an
expansion on undisturbed soils. Therefore, there should be no potential
effect to sites or properties on or eligible for listing on the National
Register of Historic Places, and in accordance with the "Memorandum of
Understanding for the Protection of Historic Properties in Louisiana Regarding
LPDES Permits" no consultation with the Louisiana State Historic Preservation
Officer is required.
XII. Tentative Determination:
On the basis of preliminary staff review, the Department of Environmental
Quality has made a tentative determination to reissue a permit for the
discharge described in the application.
XIII. Variances:
No requests for variances have been received by this Office.
XIV. Public Notices:
Upon publication of the public notice, a public comment period shall begin on
the date of publication and last for at least 30 days thereafter. During this
period, any interested persons may submit written comments on the draft permit
and may request a public hearing to clarify issues involved in the permit
decision at this Office's address on the first page of the fact sheet. A Fact Sheet and Rationale for Entergy, Waterford 3 Steam Electric Station
