SAN LUIS OBISPO COUN'IY The California Regional Water Quality Control Board, Central Coast Re-gion (hereafter Board), finds that:
- 1. We Pacific Gas and Electric Compary (hereafter discharger) appli-i ed for waste discharge requirements ard a permit to discharge wastes under the National Pollutant Discharge Elimination System ard was issued a Permit on April 9,1976 Order No. 76-11. The Discharger applied for reissuance of the permit by subnission of a preliminarf Report of Waste Discharge dated January 27, 1981. The
(' NPDES Permit application form 2. C. Part V; A, B, & C. , was crxn-pleted June 26, 1981. An analysis for toxic constitutents of the discharge was subnitted to the Regional Board on June 26, 1981.
Further analyses will be conducted after commercial operation be-l gins. Additional factual information was subnitted by the dis-l charger throughout the public hearirg process. We Board has re-quested a$ditional information on alternative nethods of reducing heat ard volume of the discharge.
l
- 2. We discharger proposes to discharge wastes from Diablo Canyon Nu-
' clear Power Plant into the Pacific Ocean at Diablo Cove, a water of the United States, at pints 12 miles southwest of San Luis Obispo (Latitude 35* 12', Iongitude 120' 51') and as shown on At-tachnent "A" included with this Order.
- 3. We potential 2.67 billion gallon per day discharge consists pri-marily of heated seawater. 'Ib this flow are a3ded smaller amounts of in-plant chemical wastes and low-level radioactive wastes.
- 4. Waste discharges are shown schematically on Attachment "B" includ-ed with this Order and described as follows:
k i
l l
1 Order No. 82-24 )
Discharce 001 D-Licuid Padioactive Waste Treatment System Effluent, 3 x 10' GPD (Intermittent)
Radioactive liquid wastes fran the reactor system will be col-lected, treated, and nonitored in a radioactive liquid waste treatment system. This system includes storage tanks to per-mit radioactive decay, ion exchangers, and filters to renove radioactive matter frcm the waste streams. High-level wastes prcduced by these processes (evaporator concentrates, ion-exchange resins, filter media) will be collected and packaged for ultimate off-site shipment to an approved burial site. -
After decay and/or treatment, individual batches of low level liquid waste will te sampled and analyzed to determine compliance with discharge limits. The batch will then be discharged through a 5-micron filter into the cooling water discharge. Wastes fran other plant systems discharged into this system include baric acid, lithium hydroxide, sodium hy-droxide, anmonium hydroxide, hydrazine, scdium sulfate, chemi-cal laboratory drains, hot shower and laundry wastes, metal cleaning wastes, and a portion of the firewater system flush water. Treatment includes distillation and filtration. .
J Discharge 001 E-Service Cooling Water 5.62 x 106 GPD
\
'Ihis system prcnides once-through cooling water for the ser-vice cooling water system.
Discharge 001 F-Turbine Building Sump, 9.8 x 104 GPD (Intermittent)
Floor drainage from the turbine building and reverse osnosis l
equipment room, as well as a portico of the firewater system flush, will be callected in sumps and treated in an oil-water
( separator prior to discharge.
Discharge 001 G-Reverse Osmosis Blowdown, 7.2 x 10 4 GPD Waste frcm a reverse osmosis demineralizaticn systen contain-ing dissolved solids, sulfuric acid, sodium hexametaphosphate, sodiun hypochlorite an3 sodium bisulfite (for dechlorination) will be discharged to the cooling water stream.
! Discharge 001 H-Condensate Demineralizer and Seawater Evacorator D2mineralizer Recenerant, 5.2 x 104 GFD (Intermittent) l a.) Waste regenerant solution fran the steam-cycle condensate demineralizer will normally te discharged once per day for each unit.
t
' The discharge constituents are salts present in seawater whi6 enter the steam cycle through main condenser leak-age, iron and copper corrosion products with added sul-furic acid (1,700 paunds per regeneration), sodium hy-droxide (850 pounds per regeneration) and calcium 61o .
ride (65 pounds per regeneration).
Order No. 82-24 -
Discharge 002 - Intake Structure Buildino Floor Drains, 3 x
) 103 GPD (Intermittent)
Drainage from within the cooling water intake structure, as well as a porticn of the firewater systen flush, will be col-lected in sumps and discharged inside the breakwater adjacent to the intake racks.
Discharge 003 - Intake Screen Wash, 5.62 x 105 cpo Solid material collected on the intake screens that is native to the ocean will be peped back to the ocean at a point lo-cated at the foot of the west breakwater of the intake cove.
Discharge 004 - Thermal Effects Laboratory Discharge 1.44 x 100 GPD Seawater is pumped through tanks used for observation of, and experimentaticn with, marine organisms aM discharged to the intake cove.
Discharge 005 - Yard Storm Drains, Flow Not Determined.
Stormwater runoff is collected in a drainage systen and dis-charged to the ocean near the plant cooling water intake.
This discharge al:o contains a portion of the firewater system
( ) flush.
- 5. 7bqx:rature of cooling water is proposed to be raised approximate-ly 20*F during nonnal thermal operation. The cooling water temp-erature increase tray be greater than 20*F during condenser heat treatment or transient conditions due to load rejection, steam dump,' generator trip, conditions resulting from cperation of en-gineered safety features, or during periods of reduced flow re-sulting from condenser tube sheet plugging or loss of the circu-lating water pump (s) flow. Tariodic thermal treatment of each cooling water system (about once per nonth for each of the four systems or about once per week) is proposed to demussel aM mini-mize growth of marine organisms in the piping and heat exchangers.
The required frequency of this operation varies seasonally but will normally have a duration of rot nore than a few hours per
. month. The maximum temperature difference between intake and dis-charge during demusseling is expected to be 50*F. if pt r.ps of cnly
'one unit are operating.
- 6. A chlorination system is proposed to ccytrol slime ard algae in the once-through condenser cooling water.
- 7. Evidence presented at the hearings indicates that if dilorination is used, the concentration of chlorine allowed in the discharge will minimize degradation of beneficial uses.
I 8. Sewage will receive treatment in septic tanks prior to discharge to leachfields.
Order No. 82-24 )
- 15. Effluent limitation guidelines for the Steam Electric Power Gener-ating Point Source Category have been promulgated by the United States Environmental Protection Agency (EPA) requirirg the appli-cation of the best practicable control technology currently avail-able (BPT) . Additional effluent limitation guidelines have been proposed, but rot promulgated, by the EPA, including effluent lim-its for best available technology econanically achievable (BAT).
Some effluent limitations contained in this order are chrived frm the promulgated federal guidelines, scrne from the proposed guide-lines, and others are based on the " Ocean Plan". 'Ibgether, they '
are considered the best available technology in the judgment of the Board. Limits are subject to reconsideration when the final guidelines are promulgated.
- 16. Best available technology economically achievable (BAT) for Diablo Canyon Power Plant should result in minimal discharge of heavy metals which result frcm dissolution of metal in the plant piping system and frcm other sources. Such quantities in many cases may be sirnificantly less than State Ocean Plan allowable concentra-tions. Discharge requirement fourd in Paragraph B.l.b. are based 3 on limits aimed at maintaining discharges of metal as low as rea .
sonably achievable.
- 17. Section 316 (b) of the Clean Water Act requires that the location, design, construction, and capacity of coolirg water intake struc-l tures reflect the best technology available for minimizing adverse
! environmental impact. 'Ihe large volume of this discharge may re-quire special procedures to minimize entrainment and impingment of marine organisms.
l
- 18. 'Ihere are difficulties in neasuring constituents listed in B.l.b.
at low levels. Many of the low volum streams have the potential
! for contributing significant concentrations of heavy metals and other toxic constituents ard for diversion to further treatment if necessary. Since analytical procedures are nore reliable at high-er concentrations, the Board considers internal monitorire of var-l ious waste streams to ba reasonable, desirable and necessary.
l l . 19. 'Ibe presently available method for calculation of toxicity in Sea-water does not allow for masurement of lower limits than that given in B.l.b.
- 20. Waste discharge requirements for this discharge are exempt frcm the prcuisions of the California Environmental Quality Act (Public Resources Code, Section 21000 et seq.) in accordance with Section 13389 of the California Water Code.

Order No. 82-24 '
(c) Sorre chemicals will be added to the water used for cooling; s however, the c:ncentration of these chemicals in Diablo Cove is not expected to have adverse effects on aquatic life.
(FES) S e NEC staff will require that, during heat treat-ment, ro chemicals that can te controlled te added to the effluent stream (FES, p. 3-50). Se NRC staff will require that the effluent be monitored for total available chlorine and the cove, for acute and chronic effects (FES ) and that total available chlorine be limited to 0.1 ppn in the dis-charged cooling water (FES, p. 3-46).
(d) Sere will be very little, if any decline in the concentra-tion of dissolved oxygen in' the discharged cooling water.
(FES) .
(e) %e ES stated: the thermal discharge from the plant will cause an ecological shift in benthic organisms and fish that will result in an increase in the nurrber of warmwater- tol-erant forms. The higher temperatures in Diablo Cove may cause those parts of the bull kelp that are near the surface to degenerate earlier in the year thrn they normally do; at raast, 2 or 3 acres will be affected. h e higher temperatures will also increase the feeding activity of the giant sea urchin, which competes with the abalone for the existing food supply (mainly kelp); this may letd to a decline in the e abalone population unless measures are taken to control the
( urchin. A total of 110,000 abalone may be lost as a result of the staticn operation.
(f) The Mdendum predicted loss of 10-20 acres of bull kelp, but concluded that this will not be a serious impact to those aquatic species that depend on kelp for food cr habitat. (p.
5-4). Because the populations of abalone ard sea urchins within D.C. have been reduced to a small fraction of their former abundance primarily due to factors unrelated to the plant (including sea otter predation, copper discharge from the plant ard a red tide (Mdendum, p. 2-21), the additional t
l impact of the thermal plume will be small (Mdendum). How-ever, the Cove will not afford a viable habitat for abalone in those areas where the thermal plume remains in constant contact with the bottom. (Mdendum p. 5-5)
(g) No adverse effect on phytoplankton populations is expected, because of the rapid regeneration times ard large stocks available for recruittrent from outside Diablo Cove. A mor-tality of as much as 8.5% of the zepplankton passing through the cooling system rray occur, but the generation times for California zcoplankton are generally 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 8 weeks, and recruitment from the cpen ocean will be copious; therefore, the impact on the local ecosysten is believed to be insigni-
! ficant. (FES) l Some jellyfish will be killed in the intake structures as a
( (h) result of impingement. The ecological consequences of this loss are expected to te s:rall. (FES) i i

4 Order No. 82-24 (q) We issm of alternative coolirg syste:rs will be decided by the California Regional Water Quality Control Board in connee-tion with the applicant's request for an exemption fran appli-cable thermal discharge prohibitions under Section 316(a) of the EKPCA. (Addendum)
- 22. Testirrony received by the Board during the hearing shows that the large volume of the proposed discharge combined with the tempera-ture increases in the proposed discharge may not assure protection of some beneficial uses of water within Diablo Cove. Temperature ,
levels in Diablo Cove, especially during demusseling operations, may cause stress of ard increase mortality rates of marine organisms.
- 23. Wat Pacific Gas and Electric Company subnitted on March 30, 1982, the technical reports required by the Board entitled " Thermal Discharge Assessment Report" and " Assessment of Alternatives to the Existing Ccoling Water System". -
- 24. Implemntation Provisior.s of the " Water Quality Control Plan for Control of Temperature; in the Coastal and Interstate Waters and .
Enclosed Bays and Ltuaries of California" state that " Existing y" ard future dischargers of thermal waste shall conduct a study to define the effect of the discharge on beneficial uses and, for ex-istirg discharges, determine design and operatirg changes which would be necessary to achieve compliance with the provisions of this plan."
- 25. We Ocean Plan states that "The Regional Board shall require dis-chargers to conduct self-rronitorirg progrars and submit reports necessary to determine compliance with the waste discharge re-quirements, and may require dischargers to contract with agencies or persons acceptable to the Regional Board to provide conitoring reports. Such nonitority programs shall comply with Guidelines for Mcnitoring the Effects of Waste Discharges on the Ocean which shall be issued by the Executive Director of the State Board."
- 26. On July 13, 1981, the Board notified the discharger and interested agencies ard persons of its intent to revise waste discharge re-quirements for the proposed discharge and has provided them with an opportunity for a public hearity ard an opportunity to subnit their written views and reconrnendations.
- 27. We Board in public rneetings on Sept.11 & 24, Oct. 9, 29 & 30,
!bv.11 & 14,1981, Jan.14, May 14, and June 11, 1982 considered all con =ents prtainirg to the discharge.
