' Specification The cooling water effluent temperature at the discharge _ structure shall not _ exceed 90*F except for brief periods for operational adjustments of.the dilution flow, or as necessary to enable the station to meet emergency load demands on the licensee's power supply system. If the 90'F limitation is exceeded for as long as 4 hours in any 24-hour _ period,.the effluent temperature shall be decreased as necessary by reducing the station's power operating level and the AEC shall be notified in accordance with non- . routine reporting procedures - (Section 5.6.2.C). Monitorina Requirement O. Plant water discharge temperature shall be continuously recorded at-the discharge structure. An. alarm will be provided in the Control Room to' indicate the status of this temperature. During periods when the measuring equipment-is defective or under repair,. alternate instrumentation shall be provided within 4 hours during water discharges or representative data readings of the discharge water temperature shall be logged every 4 hours during water dis-charges using a handheld thermometer. Basis The 90*F effluent temperature.was selected by the CRWQCB as the ' maximum permitted for Rancho Seco. The AEC's environmental renew (see the Final Environmental Statement) did.not reveal. j_ that exposure to higher temperature discharges (which could result without prior mixing with cooler dilution water) for short j periods of time'would have significant impacts on biota. l l-Normally, between 800 and 1000 spa of plant affluent with chemical impurities'will be' discharged to Clay Creek. Little, if any, will reach Hadselville Creek due to irrigation use of the effluent;- however the water may reach Hadselville Creek and the Consunnes River in the winter.- During-the summer, Rancho Seco may have to add up to 3,200'gpa of Folsom South Canal water to dilute the plant ' effluent so that' the discharge temperature will not exceed ^' 90* F.- 4-

-( channel,. including equipment actuation, alarm, or trip and shall be deemed to include the channel test. 1.24 Environmental' Release Point - The location on any effluent release -line, stack tube pipe or similar conduit from the site, beyond which the licensee has no control, as referenced by Criterion 60 and 64, 10 CFR Part 50 and 10 CFR Part 20.106. 1.25 Principle Isotopes - Those radionuclide isotopes which constitute 95% of the total activity. 1.26 Critical - The term " critical," as used in Regulatory Guide 4.1 on " Measuring and Reporting of Radioactivity 174 the Environs of Nuclear Power Plants," is defined in ICRP Publication 7 approximately as follows: certain nuclides and certain expor re pathways are much more important than others in t'a situation of a given nuclear power plant on a specific site. These important pathways (and nuclide's) are designated " critical". They are treated in the AEC's Final Environmental Statement and are the pathways generally proposed to be monitored in these Environmental Technical Specifications. j -3.

The discharge-shall not cause fungus, slimes or other bio-logical growths in the receiving waters or along the creek banks. Monitoring Requirements A. Plant water discharge conductivity shall be recorded con-tinuously at the discharge structure. An alarm will be provided in the Control Room to warn the operator prior to exceeding a level of conductivity which corresponds to the specification limit. If the setpoint is exceeded on the conductivity monitor, the discharge will be diluted to bring the dissolved solids concentration below the specification. B. During periods when the discharge conductivity monitor is out of' service, alternate instrumentation'shall be provided within 4 hours or grab samples will be taken every 4 hours h' during water discharges. C. The discharge water course will be inspected weekly at 100 yards downstream of the site discharge, 100 yards up Hadselville Creek from the confluence of Hadsciv111e and Clay Creeks, 1 and 100 yards downstream of the confluence of 11adselville and Clay Creeks for pollutants, oil, grease slicks, scum, foam or undesirable biological growths. Records of each inspection will be documented, indicating the individual, his findings and investigation made to determine the cause, l Basis i All plant effluent water will be transferred through the waste water' system either directly to Clay Creek or-temporarily to one .of two'500,000 gal.-retention basins before release'to the creek.- The restrictions require that. discharged ~ waste water not exceed a monthly average concentration of 800 mg/i total dissolved solids, placing the water in Class II for21rrigation use. ~ The combination of-treatment.and dilution of the station effluent water, coupled with the continuous monitoring program, will assure that effluent quality conforms with the CRWQCB standards-and will permit safe disposal of. effluent to the public domain. -) l

t The maximum ' discharge velocity 'will be 2.6 f t/sec. at the. exit - with a total flow of 4,000 gym. The average discharge velocity will be'O.66 ft/sec. at the 1,000 gym discharge flow rate.

Chlorine Objective To prevent discharging chlorine at concentration levels intolerable to living organisms. Specification-The effluent water shall contain total residual chlorine not to exceed a maximum rate of 0.2 mg/ liter. Monitoring Requirement Grab samples of the effluent water shall be collected and analyzed weekly for total residual chlorine. The samples will be obtained from the outlet of the discharge structure at the interval after chlorination which is found experimentally to indicate the =av1== 7 - concentration. If there is no chlorination during the scheduled . 1 (.. sample period, the sample will be obtained during the following. -period. Basis Interni.ttent use of chlorine will be required for cont.21 of algae in the circulating water system and will result in periodic . low residuals of chlorine in the effluent water which will not be + harmful to living organisms. The limit of 0.2 ag/ liter was established by the CRWQCB. 2.3 Dissolved Solids Objective To prevent discharging' materials that would make the effluent unusable for-irrigation, or that would be detrimental to the environment surrounding the-receiving water. . Specification A. The total' dissolved' solids shall not exceed a maximum con-centration.of.850 mg/i or a maximum daily amount of 34,000 lbs. f' -B. 1The total dissolved solids shall not' exceed a 30-day average G/ ' . concentration of 800 mg/i or a 30-day average daily amount .of 32,000 lbs.. - 5'- r .--I . -=.. -. - - - - -. ,,e.r-

The effluent water shall not contain dissolved boron in excess of 1.2 mg/L or 48 lbs per day and 1.0 mg/L or 40 lbs/ day when ~ averaged over 30 days. C.. The effluent. water shall not contain dissolved zine in excess 'of 0.4 mg/L or 16-lbs per day and 0.3 mg/L or 2 lbs/ day when averaged over 30 days. i-Monitoring Requirement -Grab: samples of'the plant effluent water for oxygen analysis shall be , obtained 100 yards downstream of the plant discharge and from Hadsel-ville Creek at points 100 yards upstream and 100 yards downstream of the confluence with Clay Creek and analyzed weekly. These samples will give an indication of the quality of the effluent water from the plant and be representative of the overall plant operations. Samples of the affluent water for boron and zine analysis shall be collected and atalyzed on a monthly 24-hour composite schedule. The samples will be obtained from the outlet of the discharge structure. Basis All limite.tions in this specification were established by the CRWQCB. L The Aquatic Life Advisory Committee

  • recommends that the dissolved oxygen content of warm-water fish habitats be not less than 5 mg per liter during I'

at least 16 hours of'any 24-hour period. It may be-less than 5 mg per liter for a period not to exceed 8 hours within any 24-hour. period, but at no time;should the dissolved oxygen content be less than 3 mg per liter. The above analyses indicate that there is a reasonable assurance that a minimum of 5.0 mg per'11ter dissolved oxygen in the plant effluent will not adversely affect fish life in the receiving waters.. Dissolved oxygen of the effluent waters should be near saturation because of the aeration within the cooling towers. The minute quantities of boron and zinc'are received from the"Folsom South Canal as makeup water and concentrate in the cooling towers.- Dilution before discharge may be required to reduce the levels below these limits. These-elements may-be present'in the plant, but are mainly derivec from the concentrating mechanisms of the cooling towers and, in general, are not of plant origin.

Column 2, for unrestricted areas. This specification provides assurance that no member of the general public 'will;be exposed to liquid containing radioactive materials in excess of limits: considered permissible under the Commission's Rules and Regulations .using the guidelines given in Regulatory Guide 1.21. Specifications 2.6.1'B and 2.6.1.C establish-the upper limits for the -release of' radioactive materials in liquid effluents. The intent of these Specifications 1s to permit the licensee the flexibility of operation to_ assure that the_public is provided a dependable source of power under unusual operating conditions which may temporarily result in releases higher than the levels normally achievable when the plant-and the liquid waste treatment aystems are functioning as designed. Re-leases of up to these limits will result in concentrations of radioactive l' material in liquid wastes at small percentages of the limits specified j in'10 CFR Part 20. Specifications 2.6.1.D and 2.6.1.E require that suitable equipment to con-trol and'ronitor the releases of-radioactive materials in liquid wastes are operating'during any period these releases are taking place consistent I with,the_ requirements of 10 CFR Part 50, Appendix A, Design Criterion 64. f f' Specification 2.6.1.F. requires that the licensee maintain and operate the equipment installed in the liquid. waste systems to reduce the release of radioactive materials in liquid effluents to as low as practicable consistent with the requirements of 10 CFR Part 50.36a. Normal use and maintenance of installed equipment in the liquid waste system provides reasonable assurance that-the quantity released will not exceed the design objective. In order to keep releases of radioactive materials as-_ low as practicable, the specification requires operation of equipment whenever 'it appears that the projected cumulative discharge rate will exceed 'one-fourth of.this design objectiv'e annual quantity during any calendariquarter. ' Specification 2.6.1.G.' limits the amount of radioactivity that may be i inadvertently released to the environment to an amount'that will not l- . exceed the: Technical Specification limit. ~ In addition to limiting conditions for operation listed under Specification 2.6.1.B and :2.6.1.C,the' reporting requirements of s-l c Specification 2.6.1.H : delineate that the licensee shall identify the cause whenever the release rate of radioactive materials in liquid wastes: exceeds one-half the' design objective: annual quantity during any. calendar. quarter and describe the proposed program of action to reduce.such; release rate to design objective levels on

. ( of each unit. Meteorological calculations for offsite locations were performed, and the most' critical one was selected to set the . release _ rate. TheLeontrolling distance is 640 meters to the north. The gamma dose contribution was determined using the equation 7.63 in Section 7-5.2.5 of Meteorology and Atomic Energy - 1968. The releases from vents are considered to be ground level releases which acould result in a beta dose from cloud submersion. The beta dose contribution was determined using Equation 7.21, as described in Section 7-4.1 of Meteorology and Atomic Energy - 1968. The beta dose contribution was determined on the basis of an infinite cloud passage with semi-infinite geometry for a ground level release (submersion. dose). The beta and gamma components of the gross -radioactivity in gaseous effluents were combined to determine the allowable continuous release rate. Based on these calculations, a continuous release rate of gross radioactivity in the amount specified in 2.6.3. A(1) will not result in offsite annual doses above background in excess of the limits specified in 10 CFR Part 20. The average gamma and beta energy per disintegration used in the equation of Specification 2.6.3.A(1) will be based on the average . composition of gases determined from the plant vent and ventilation exhausts. The average energy per bata or gamma' disintegration for those radioisotopes determined to be present from the isotopic analyses are given in Table 2.6-3. Where isotopes are identified that are not listed in Table 2.6-3, the gania energy are determined from Table of Isotopes, C. M. Lederer, J. M. 3ollander, and I. Perlman, Sixth Edition,1967, and the beta' energy shall be as given in USNADL-TR-802, II. Spectra of Individual Negatron Emitters (Beta Spectra), O. Hogan, P. E. Zigman, and J. L.

(?J Specification A.

-During the initial startup and semiannually, noise level measure-ments shall be performed along the site boundary at 200 yard intervals. B. Records shall be maintained for all noise measurements and documented in special log book specifying noise level, location, instrumentation used and personnel making the measurements. Report Requirement The measured results of sound pressure level at the site boundary during normal plant operations at full power and at various weather-conditions shall be within normally acceptable NC-40 curve (see ' attached) for noise criteria as defined in Section 1. 1 Sound levels in excess of NC-40 curve for " clearly unacceptable" ranges shall be reported as required in Section 5.6.1. Bases

A typical power plant is a complex source of noise, making operational

.( . analysis of anticipated noise levels difficult and of little value Prime sources of noise at the Rancho Seco plant are expected to be the high speed turbine driven feed pumps, the transformers, and, infre-quantly,. operation of the safety relief valves. From the standpoint of the plant operators, protective actions will be taken which are consistent with the requirements of the State of California, Division of-industrial Safety. From the standpoint of the offsite public, extrapolation of test results obtained from operating fossil fueled power plants (a far greater source of noise than a nuclear unit) in-dicates that at the site boundary, the sound pressure level attrib-utable to plant operations at normal conditions of operations and weather is expected to be compsrable to the NC-40 curve for noise criteria. 'At the nearest dwelling, approximately one mile away, the sound pressure level would equal daylight. background conditions, with on'y. inoffensive. low octave rumble apparent at night. There is no:real criteria to-determine noise. Since noise 1s a relative' term,lthe measurements will be performed by measuring sound power as specified in the definitions. However, if complaints are' received from the local residents, this will be a criteria for consideration of corrective actions. '3.5 .

Specification The thermal plume will be plotted on a map showing the intersection of the plume along State Highway 104 at ground elevation whenever such intersections are observed. Appropriate action will be initiated to warn motorists of possible fog cover at locations east and west of the plant. Reporting Requirement The extent of the fogging and duration shall be recorded and a report will be made to the AEC in accordance with Section 5.6.1 of these specifications. Bases There is little that can be done to prevent infrequent plume inter-section with the ground since this will be greatly dependent on atmospheric conditions. If there is an extended period of fogging, the plant power may have to be increased to produce maximum updraft to produce a greater lift force to penetrate the lower atmosphere. The vapor plume from the cooling towers has received extensive analysis. Environmental Report, Table 9.4-1 Incremental Environment Effects, Section 3.1 states that there will be zero hours of fogging that will interfere with ground and air transportation. The effects are discussed at length in Appendix 3C of the Rancho Seco Environ-mental Report and stated as " negligible" in the Final Environmental Statement. 3.6 Reservoir Drawdown Objective To provide notice when =ater for the recreational resources at the reservoir may not be available. Specification The licensee shall record in its semiannual operating reports any instances of deviations from the followins requirements which are included in a contract between the licensee and the State of California Department of Water Resources: "The_ reservoir level shall be maintained as ne rly as practicable at elevation 240 feet but in no event less than 239 feet, provided that: 1.

Between-November 1 and March 31 each year, the reservoir may be operated so that the pool elevation is not less than 237 feet. 3. To meet a physical need for water at Rancho Seco which cannot be satisfied from other sources, the reservoir may be drawn below elevation 237 feet. 4. The reservoir may be drawn below the above elevations for another purpose only with the prior written consent of the State. " Monitoring Re'quirement -A visual elevation monitor calibrated to read reservoir level is installed in the Control Room. The levt.1 shall be recorded and logged daily. When the visual monitor is inoperable, a direct reading shall be obtained and recorded from the reservoir level indicator on the inlet-outlet tower. Bases The availability of the Folsom South Canal should be high. During -the brief outages of the canal,. makeup from the reservoir will be required. To provide sufficient makeup water to Rancho Seco when the canal is not available, drawdown below 239 feet will be allowed. Decreasing the water level from the normal 240 feet level to-239 ft'et will not affect the recreational facilities nor endanger any aquatic species. At 237 feet, the recreational facilities are de-creased but still no aquatic life is endangered. Below 237 feet elevation,.many. factors must be considered, which will be evaluated .before obtaining.the written consent of the State. .h i :.30.-
