-RETURN RECEIPT REQUEST File No.: LA0042731 AI No.: 2889 Activity #: PER20040001 Mr. William H. Spell, Senior Environmental Specialist Entergy Operations, Inc.

River Bend Station 5485 U.S. Highway 61 St. Francisville, Louisiana 70775 RE:

Louisiana Pollutant Discharge Elimination System (LPDES) permit to discharge cooling tower blowdown, low volume wastewaters, maintenance wastewaters, clarifier underflow, treated sanitary wastewater and metal cleaning wastewater to the Mississippi River (via Outfalls 001, 101, 201, 301, 401, 501,601 and 006), and stormwater runoff, vehicle washwater, air conditioning condensate, cooling tower drift, low volume wastewaters and maintenance wastewaters to Grant's Bayou thence to Alligator Bayou thence to Thompson Creek (via Outfalls 002, 003, 004, 104 and 005) from an existing steam electric generating facility located at 5485 U.S. Highway 61, St. Francisville, West Feliciana Parish.

Dear Mr. Spell:

This Office has not received comments from the general public or from Entergy Operations in response to the public notice published in the Office of Environmental Services Public Notice Mailing List on January 25, 2006 and the ST. FRANCISVILLE DEMOCRAT on January 26, 2006. However, comments were received from Entergy Operations by an email dated April 3, 2006. Below is a summary of the comments and this Office's responses:

Comment 1:

Part 1, Page 4 of5, Outfall 101 - There is an RO unit in the radwaste system different than the others previously mentioned.

Response to Comment 1:

This low volume wastewater has been added to the wastewater description for Internal Outfal 101.

Comment 2:

The permittee has requested that this Office remove the monthly average limitations established in the permit for Internal Outfalls 101, 201, 301, 401, 501 and 601 due to the intermittent nature of the discharges.

Response to Comment 2:

The above referenced monthly averages established in the permit were taken from the federal effluent guidelines for steam electric generarting facilities (40 CFR 423). In accordance with EPA interpretation of the effluent guidelines, where a monthly average and daily maximum limitation are established in the guideline, both limitations shall be placed in the permit. Therefore, your request to remove the monthly average limitations is denied.

Entergy Operations, Inc.

LA0042731 / Al No. 2889 Page 2 C

Outfall 201 (Part IPage 5) - Change "Outfall 201" to "Internal Outfall 201" since it is currently designated incorrectly.

Response to Comment 3:

This change has been made in the permit.

Comment 4:

Part 1, Page 12 of 15, Outfall 004 - Add domestic (potable) water to the outfall description.

Response to Comment 4:

This Office has determined that the addition of this effluent to Outfall 004 will not change the established monitoring requirements; therefore, potable water has been added the wastewater description.

Comment 5:

Part AI, Paragraph R - The permittee referenced the date listed in the first paragraph of Paragraph R, regarding the Zebra Mussel Treatment Program plan, and indicated that an updated plan has since been submitted to this Office. Should the date of the updated plan be referenced?

Response to Comment 5:

It is understood that the plan for Entergy's Zebra Mussel Treatment Program is frequently updated.

Therefore, the first paragraph in Part II, Paragraph R has been modified to read as such: "The terms and conditions of the most recently approved zebra mussel treatment program submitted by Entergy Operations, Inc., River Bend Steam Electric Station shall be enforceable as if part of this permit."

Comment 6: Part II, Paragraph R - A typo was found in the last paragraph, third line...the first words should read "If chlorine is..."

Response to Comment 6:

This change has been made to the permit.

Comment 7-.

The permittee requested to add some language regarding 316(b) applicability to Part II of the permit.

Response to Comment 7:

This Office only incorporates language regarding 316(b) applicability/compliance in the Part II of permits for facilities that will be required to follow the information gathering, submittal and monitoring requirements required by the rule. This Office has determined that the River Bend Station does not fall under the applicability requirements of the rule, and the fact sheet, which accompanied the draft permit, included a section that addressed the matter. Therefore, no further language is needed in the permit.

Pursuant to the Clean Water Act (33 U.S.C. 1251 e g.), and the Louisiana Environmental Quality Act (La. R.S. 30:2001, pi =.), the attached LPDES permit has been issued. Provisions of this permit may be appealed in writing pursuant to La. R.S. 2024(A) within 30 days from receipt of the permit. Only those provisions specifically appealed will be suspended by a request for hearing unless the secretary or the assistant secretary elects to suspend other provision(s) as well.

Significant lethal effects are herein defined as a statistically significant difference at the 95% confidence level between the survival of the appropriate test organism in a specified effluent dilution and the control (0% effluent).

a.

Part I Testing Freauency Other Than Monthly

i.

The permittee shall conduct a total of two (2) additional tests for any species that demonstrates significant lethal effects at the critical dilution.

The two additional tests shall be conducted monthly during the next two consecutive months.

The permittee shall not substitute either of the two additional tests in lieu of routine toxicity testing, unless the specified testing frequency for the species demonstrating significant lethal effects is monthly.

The full report shall be prepared for each test required by this section in accordance with procedures outlined in item 4 of this section and submitted with the period discharge monitoring report (DMR) to the permitting authority for review.

ii.

If one or both of the two additional tests demonstrates significant lethal effects at or below the critical dilution, the permittee shall initiate Toxicity Reduction Evaluation (TRE) requirements as specified in item 5 of this section.

The permittee shall notify this Office in writing within 5 days of the failure in any retest, and the TRE initiation date will be the test completion date of the first failed retest.

A TRE may also be required due to a demonstration of intermittent lethal effects at or below the critical dilution, or for failure to perform the required retests.

iii.

If one or both of the two additional tests demonstrates significant lethal effects at or below the critical dilution, the frequency of testing for this species shall be once per quarter for the life of the permit.

iv.

The provisions of item 2.a are suspended upon submittal of the TRE Action Plan.

d.

The permittee shall submit a Final Report on Toxicity Reduction Evaluation Activities no later than twenty-eight (28) months from confirming lethality in the retests, which provides information pertaining to the specific control mechanism selected that will, when implemented, result in reduction of effluent toxicity to no significant lethality at the critical dilution.

The report will also provide a specific corrective action schedule for implementing the selected control mechanism.

A copy of the Final Report on Toxicity Reduction Evaluation Activities shall also be submitted to the above addresses.

e.

Quarterly testing during the TRE is a minimum monitoring requirement.

LDEQ recommends that permittees required to perform a TRE not rely on quarterly testing alone to ensure success in the TRE, and that additional screening tests be performed to capture toxic samples for identification of toxicants.

Failure to identify the specific chemical compound causing toxicity test failure will normally result in a permit limit for whole effluent toxicity limits per federal regulations at 40 CFR 122.44(d)(1) (v) and state regulations at LAC 33:IX.2707.D.I.e.

17. Monthly Average (also known as Daily Average), other than for fecal coliform bacteria, discharge limitations are calculated as the sum of all "daily discharge(s)" measured during a calendar month divided by the number of "daily discharge(s)" measured during that month. When the permit establishes monthly average concentration effluent limitations or conditions, and flow is measured as continuous record or with a totalizer, the monthly average concentration means the arithmetic average (weighted by flow) of all "daily discharge(s)" of concentration determined during the calendar month where C = daily discharge concentration, F = daily flow and n = number of daily samples; monthly average discharge =

C, F, + C2F2 +... + CF, F, + 12 +... + F, When the permit establishes monthly average concentration effluent limitations or conditions, and the flow is not measured as a continuous record, then the monthly average concentration means the arithmetic average of all "daily discharge(s)" of concentration determined during the calendar month.

The monthly average for fecal coliform bacteria is the geometric mean of the values for all effluent samples collected during a calendar month.

18. National Pollutant Discharge Elimination System means the national program for issuing, modifying, revoking and reissuing, terminating, monitoring and enforcing permits, and imposing and enforcing pretreatment requirements, under Sections 307, 318, 402, and 405 of the Clean Water Act.

22. For fecal coliform bacteria, a sample consists of one effluent grab portion collected during a 24-hour period at peak loads.

23.The term MGD shall mean million gallons per day.

24.The term mg/L shall mean milligrams per liter or parts per million (ppm).

25.The term UgIL shall mean micrograms per liter or parts per billion (ppb).

26.The term noiL shall mean nanograms per liter or parts per trillion (ppt).

27. Weekly average, (also known as 7-day average), other than for fecal coliform bacteria, is the highest allowable arithmetic mean of the daily discharges over a calendar week, calculated as the sum of all "daily discharge(s)" measured during a calendar week divided by the number of "daily discharge(s)" measured during that week.

When the permit establishes weekly average concentration effluent limitations or conditions, and flow is measured as continuous record or with a totalizer, the weekly average concentration means the arithmetic average (weighted by flow) of all "daily discharge(s)" of concentration determined during the calendar week where C daily discharge concentration, F = daily flow and n = number of daily samples; weekly average discharge =

CIF 1 + C2 F2 +... + CnFn F, + F2 +... + Fn When the permit establishes weekly average concentration effluent limitations or conditions, and the flow is not measured as a continuous record, then the weekly average concentration means the arithmetic average of all "daily discharge(s)" of concentration determined during the calendar week.

The weekly average for fecal coliform bacteria is the geometric mean of the values for all effluent samples collected during a calendar week.

28. Sanitary Wastewater Term(s):

a. 3-hour composite sample consists of three effluent portions collected no closer together than one hour (with the first portion collected no earlier than 10:00 a.m.) over the 3-hour period and composited according to flow, or a sample continuously collected in proportion to flow over the 3-hour period.
