Enclosure 1 contains a February 16, 1983 letter from Mr. Paul J. Tra'ina of the Environmental Protection Agency (EPA) transmitting the NPDES permit for the Sequoyah Nuclear Plant. The permit is being reissued and becomes' effective on April 1,1983 It will be in effect for a five-year period and will expire March 31, 1988. The reissued permit will replace the existing permit.

In regard to Discharge Serial No. 103, compliance witb suspended solid' limits has not been immediately feasible. For this rcaon, the EPA has

-issued an Administrative Order (Enclosure 2) concerning this potential noncompliance. The order includes a compliance schedule for completing a treatment' system to assure compliance with discharge limitations.

Enclosure 3 is a January 31, 1983 letter from Mr. Paul E. Davis of the Tennessee Division of Water Quality Control to Mr. Traina providing certification of the NPDES permit. The certification contains several conditions which are incorporated by reference into the NPDES permit.

g 5/ River temperature measurements shall be made at monitoring statio s located approximately 1200 feet '

downstream of the dif fuser (one at each edge of the mixing zone). Temperature data shall be I measured as in Footnote 1. With one leg of theidiffuser operating, the temperature at the left bank monitor (#8) will be used to demonstrate compliance and with two legs of the diffuser in operation, the temperatures at each of the two downstream monitors (#8 and #11) will be individually used.

I Upon approval by the Director, Water Management Division, and the State Director, compliance with

! the river limitations (river temperature, temperature rise, and rate of tempetature change) shall

! be monitored by means of a numerical model that solves the thermohydrodynamic equations governing the flow and thermal conditions in the reservoir. This numerical model will, utilize measured values

{ of the upstream temperature profile, flow through the diffuser pipes, temperature of the diffuser g

e discharge, discharges at Watts Bar and Chickamauga Dams, and the diffuser performance characteristics.

! Field tests shall be' conducted to establish the diffuser performance characteristics to be used in the

{ numerical model. -

a. We "aserage monthly discharge" is defined as the total rass of all daily discharges sampled ard/or measured during a calendar acnth on which daily discharges are sampled and measured, divided by the number of daily discharges 'sai: pledand/or measured during such month. It is, therefore, an arithmetic mean found by adding the weights of the pollutant found each day of the month ar4 then dividing this sum by the number of days the tests were reported.

His limitation is identified as " Daily Awrage" or "Menthly Awrage" in Part I of the permit and the awrage monthly discharge salue is -

reported in the "Awrage" column under " Quantity" ~en the Discharge Monitoring Report (IER).

b. The "awrage weekl; discharge" is defined as the total : ass ot all daily discharges sampled and/or measured during the calerdar week cn which daily discharges are sampled and/or measured during such week.

identitied as " Weekly Awrage" in Part I of the permit ard the -

awrage weekly discharge salue is reported in the " Maxi =um" column under " Quantity" on the EHR.

c. We " maximum daily discharge" is the total mass (weight) of a pollutant discharged during a ' calendar day. If only cne sample is taken during any calendar day the weight of pollutant calculated frcm it is the " maximum daily discharge". h is limitation is identified as " Daily Maximum", in Part I of the permit and the h'ighest such value recorded during the reporting period is reported in the

" Maximum" column under " Quantity" on the EMR.

i

d. We "awrage annual discharge" is defined as the total rass of all daily discharges sampled and/or measured during the calendar year en which daily discharges are sampled and/or measured during each week.

It is, therefore, an arithmetic mean found by adding the weights of pollutants fourd each day of the year and then dividir.g this sum by the number of days the tests were reported. B is linitation is detined as " Annual AWrage" in Part I of the permit ard the awrage annual discharge salue is reported in the " Average" colu=n under

HAMILTCN COUNTY, TENNESSEE )

NPDES PERMIT NO. TN0026450 )

ORDER PURSUANT TO SECTIONA309 CLEAN WATER ACT Pursuant to the authority of Section 30'9' of "the Clean Water Act ( the "Act"), 33 U.S.C. {1319, which has been delegated to me, I hereby make the following Findings of Fact and Violations, and Order:

FINDINGS OF FACT

1. The Tennessee Valley Authority (hereinaf ter, the Permittee) operates a facility in Hamilton County, Tennessee which discharges pollutants into the Tennessee River, a water of the United States.

2. The facility has been issued and is subject to the provisions ' of Naticnhl Pollutant Discharge Elimination System (NPDES)

Permit Number TN0026450. Said permit expired on September 30, 1980 and was extended under the Administrative Procedure Act until it was reissued on February 16, 1983.

3. Part I, Section A, page I-5 of the reissued permit provides effluent limits for the discharge from the low volume waste treatment

( pond (outfall serial number (OSN) 103). Condensate domineralizer regeneration l

I waste is normally discharged to the low volume waste pond.

. . = ,e

. } e' ,

4. Under certain circumstances, and on infrequent occasion, the condensate demineralizer regeneration waste has been diverted to the cooling tower blowdown line through OSN 014 (renumbered OSN 105 in the reissued

" permit). Part I, Section A, page 13 of 28 of the expired permit provides effluent limits for OSN 014. ,

5. The filtration system originally installed to treat the condensate demineralizer wast prior to discharge through OSN 014 did not function as designed and has been taken out of rervice.

6. In a letter to EPA dated October 1, ;982, the Permittee informed EPA that an alternate filter treatment system for OSN 014 had not yet been installed. The letter included a schedule for installation of the treatment system.

VIOLATIONS

7. The Tennessee Valley Authority has violated the terms and

conditions. in its expired NPDES Permit No. TN0026450 in that the i

,. Permittee has exceeded the effluent limits for total suspended solids as a result of discharging condensate demineralizer waste through OSU 014 (resumbered OSN 105 in reissued permit) prior to installation of an operable waste treatment system. It is expected that any future discharges of condensate demineralizer waste through. the outfall now identified as l

OSN 105, prior to installation of the alternative filter treatment system will result in violations of the ef fluent limits on total suspended solids l

l found on page I-7 of the reissued permit.

pur' scant to the provisions of Section 309(a) of the Act, it'is hereby ordered:

i

1. That should the need arise, the Permittee is authorized to ,

discharge condensate demineralizer waste through OSN 105 prior to installation of the alternate filter treatment system. Such discharge must be in compliance with all of the terms and conditions on page I-7 of the reissued permit, with the exception of the discharge limitations on total suspended solids, said limitations being suspended until the filter system is operational.

2. That the Permittee shall comply with the following schedule:

a. Filter system equipment delivered to facility -

September 1, 1983.

b. Filter system installation completed -

March 1, 1984.

i

c. Filter system operational - September 1, 1984.
