UNITED STATES Qdbb E o NUCLEAR REGULATORY COMMISSION
$ E WASHINGTON, D. C. 20555 g...+[ OCT 3 019 The Honorable Douglas H. Bosco Member, United States House of Representatives Suite 329, Federal Building 777 Sonoma Avenue .
Santa Rosa, California 95404

Dear Congressman Bosco:
Recently you received a letter-from a constituent, Mr. Jared Rossman of
~
Redway, California, and requested that we provide information to you for your response. Mr. Rossman discussed a hearing on the Humboldt Bay Power, Plant Unit No. 3 that was held in Eureka, California on September 11, 1985.
The hearing involved the disposal of water containing " dissolved chromium and other contaminants including low-level radioactive materials."
The September 11, 1985 hearing was conducted by the State of California Regional Water Ouality Control Board, North Coast Region. The purpose of the hearing was to consider a Pacific Gas and Electric Company (PG&E) request to amend the Beard's Order No. 82-85 with respect to the discharge of waste water from the site. No action by the NRC was reouested or required with respect to the request from PGRE to the California Regional Water Quality Control Board as there was no change requested for any radioactive release limits. By Order No.85-110, dated September 11, 1985 the California Regional Water Quality Control Board revised the National Pollutant Discharge Elimination System (NPOES) pemit for the Humboldt Bay Power Plant. A copy of the Board's sumary report and the NPDES permit are enclosed.
The change in the NPDES pemit was needed by PG&E to allow water from the -
4 &_ Humboldt Bay Unit No. 3 suppression chamber to be released at the rate of 7500 gallons per day following a purification (ion exchange) process.
Humboldt Bay Unit No. 3 is permanently shut down and preparations are underway for decomissioning. Part of PG&E's preparations for decomissioning is the removal of all unneeded liquids from Unit No. 3 including the water from the suppression chamber. No change in limits for radioactive releases were needed for this activity as the requirements in our regulations (10 CFR Part. 20) are specified as concentration limits for each radionuclide and as limits on potential exposure to the public.
The ion exchange system used in processing the water from the suppression chamber removes radionuclides as well as chromium to meet the limits specified in 10 CFR Part 20 of the Comission's Regulations and the State NPDES permit. ,

A partial l 14 *ing of these e sta streams includes tashwater, laboratcry water, ammpling streams, building drains, groundwater from foundation dewatering systems, etc. These wasta streams will continue to be discharged during the deccandasioning process and thereafter as a result of various continuing activities in the thit No. 3 building.
The IEC does not permit liquid radioactive unste to be discharged into the
. municipal aswer systan. It must be routed to a 61A4a! taDk, treated and
- sampled to detaraine comp 14=ar= with 300 regulations (r=dia-elides) and l
Wasta Discharge Requirementa before it may be d4=eheged to lhamboldt Bay.

Liquid low level radioactive weste d4=eheses averese two to three batches per month. Estehas average 6,200 gan ons and range from 3,500 ga u ens to 7,500 an11 mas. In tares of daily flow, thsee batch discharges have averaged 400 G D over the last 18 months. Flav values have increased only slightly during the initial stages of dara==i==ianing; however, they will increase to as high as one batch per day (7,500 WD) during late 1985 as PGAE drains the Man chamber. The -=v H= chamber contains 160,000 gallons of water and will be treated and discharged during a 30 to 60 day period.

chamber totar consists of denineralized groundwater with potassim chroante added as a carrasim inhibitor. Sodium hydroxide also is added to raise the l
pH and create an alkalian enviroment for further carrosion reduction.
i concentration of dissolved chrondian is 168 mg/1; pH is 8.9. Attachnent "B"
! is a chemical breakdown of the supression chamber water. ,
1he only constituents that have been added to the desdneralized water are sodium, hydroxide, potassi m and chroud e . Of these, the only one of
! concern is chroads. PGIE proposes to trust the taste by son exchange to the estant that chromium does not are==d 0.05 mg/1. This level is aquivalent to the ==ri = = allowable concentratim for drinking water. If chrm d a is treated to this level, all other constituents in the wastewater would be treated to =id lae levels. h potential impact af low levels of ,

discharge into E=hn1 At Bay. f Attachment 'TT is a achamatic of discharges from the Beholdt Bay Pbwer Plant. Each batch of treated suppr===4ari chamber water would be di=d-r s d et 20 GFM for a six hour period. Dilution in the malina eter channel is i
2,500:1. At the acne of initial dilution in E=haldt Bay, the dilution of ,
j suppression chamber water is 12,000:1. No adverse water quality impact will !
result from the proposed discharge of treated suppression chamber water.
1he key to preventing noter quality impacts is assuring that each batch of wastewater will be adequately treated.
PGEE proposes to treet the ==pp --!= chamber votar with an ion exchange ,

If constituents are within muaushie limits, the wesen will receive a final filtration and will be dischstged throu@ 001D into the eaalia,n inter channel. If =11==hle discharge limits are not met, the inste will be l
- passed through the treatment process again. A detailed descriptim of the treatment process is contained in Attachment "If.
Attach ==it "If also describes the steps that will be taken to monitor the treatment process and wastsweter affluent to assure that each batch is i adequately trestad. The monitoring method ennef ata of using centi === !
monitoring af electrical conductivity and pH to deterndne a " breakthrough" '
curve as shown in Attachment 'E". Grab ammples will be analyzed for chread s and correlstad to pH and conductivity. In this mannar the chromismi concentration can be detanmined instantaneourly by analysing the pH and conductivity. Estensive ammpling must be perforund during initial treatment operations in order to' produce a breakthrough curve that correlates well to other parameters. P(EE will have an atmic absception spechvi l.etameter for chrend e analysis en-site during the entire treatment period. During regular operation of the treatment system, each batch will be analyzed for conductivity and 3R Diremdum concentration will be determined by I correlation ascept for every fifth batch, which will be analyzed as a spot check.

Attn.: Mr. Tom Dunbar
Dear Dr. Joseph:
j This letter is in response to the North Coast Regional Water Quality Control Board (NCRWQCB) letter of June 3, 1985 concerning the discharge of Bumboldt Bay Power Plant suppression chamber water. ////ff I Form 1 of the NPDES permit and the $500.00 filing fee for the application of a permit revision to NPDES No. CA0005622 (Order No. 82-85) are attached. We are submitting the partially completed Form 2c at this time and will provide the remaining data on the Table B (Ocean Plan) heavy metals by August 9.
The following data are presented:
- 1. Form 2C, pages V-1(a) to V-3(a), labelled 001D/001E contains an analysis of a flow-weighted composite sample of water collected during the second quarter of 1985 (April 1 through June 30, 1985, inclusive) from the current discharge. Bowever, this sample does also include laundry effluent. 'Ihis sample was the best, sample of composited effluent from 001D presently available at the plant even though approximately 25 percent by volume was laundry effluent (001E). No suppression pool water is contained in this sample. '
- 2. Form 2C, pages V-1(b) to V-3(b) labelled Suppression Chamber, contains estimates of the concentrations of suppression chamber water constituents after treatment.
- 3. Attachment A contains an analysis of suppression pool water prior to treatment.
1
Mr. T. Dunber July 31, 1985 '
Data on the actual treatment processing system performance for processing the suppression. chamber gater will be provided af ter the start up of the processing system. A break through curve for the processing system will be determined based on the initial i test run prior to any actual discharge.
! The treatment process and proposed ef fluent monitoring program are described below The suppression chamber water will be processed on a batch basis through domineralizer beds and tasporarily stored in two on-site 7500 gallon tanks normally used to hold liquid radwaste prior to discharge through Discharge 001D. The tanks will be alternately filled with treated suppression chamber water. The water will be released through 001D in 1
7500 gallon batches. These discharges will continue for approximately one month in order to treat and discharge the j
l, entire contents of the suppression chamber. Prior to i
discharge into 001D, each tank will be sampled to ensure compliance with NPDES permit limitations. Radioactivity will also be monitored to ensure that Nuclear Regulatory Commission limits are met.
1 l
The domineralizers will be capable of processing the water
- at 50 gallons per minute (gpm) . The system consists of a
- strong acid cation bed, a strong base anion bed, and a mixed i
bed. The pH and conductivity will be monitored at several points on the system described in the flow diagram
, (attached). The discharge rate for each 7500 gallon batch l through Discharge 001D will be approximately 20 gym.
- - - The following processing and monitoring procedure is proposed: l
- 1. system Stargpp Initial run ,
- a. Upon startup of the processing system, the domineralizer effluent will be recirculated back to the suppression chamber to rinse down the beds.
Sasples will be taken of the mixed bed ifluent during i the rinse to correlate chromium concentration to pH and !
conductivity. This data will be used to establish a break through curve. This curve will be used to predict the chromium level during subsequent processing.
Monitoring of pH and conductivity levels will be done on l a continuous basis. ,
- b. Following the initial rinse down, the domineraliser ef fluent is routed to a holding tank. The initial 7500 gallon batch in the holding tank will be_ sampled and analyzed for chromium, pH, conductivity, oil and grease, and non-filterable residue. If chromium is
- CTY
Mr. T. Dunbar July 31, 1985 detected at levels above 0.05 mg/1, the initial batch will be reprocessed. If the batch meets discharge a limitations, it will be discharged through 001D.
1 Regular Operation
- c. During regular operation, atleast every fif th batch I will be sampled for chromium at the start of filling the holding tanks (to allow time for the chromium analysis) .
Each batch will be sampled and analyzed at completion for pH and conductivity to ensure compliance with the permit requirements. The pH and conductivity will also be monitored continuously during the processing described in the flow diagram (attached) and evaluated using the break through curve to determine chromium levels. This information will be used to maintain water t quality by determining when the domineralizing beds are l exhausted.
l d. In the event of resin exhaustion, indicated by the pH and conductivity levels monitored in the domineralizer ef fluent, the following actions will be taken:
1.. The flow to the holding tank will be stopped.
4 2. The pH and conductivity in the holding tank j water will be analyzed to predict the chromium i concentration.
- 3. Bolding tanks that have received domineralizer effluent with conductivity and pH values indicating l a chromium level above 0.05 mg/l will be sampled and analyzed for chromium. If chromium levels are below 0.05 mg/1, the tank will be discharged .
. 4. The exhausted resin beds will be removed and new beds installed and rinsed down prior to resuming processing.
- 5. If the chromium sample shows levels greater than 0.05 mg/1, the batch will be reprocessed through the treatment system. -
Chromium Analysis Methodoloay ,
Chromium concentration will be analyzed by an Atomic Absorption Spectrophotometer ( A. A.S.), using the direct aspiration method (EPA Method 218.1), following sample preparation as outlined in " Methods for Chemical Analysis l
Mr. T. Dunbar -4 July 31, 1985 of Water and Wastes" (EPA 600/4-79020). The A.A.S. will be calibrated using known standards prior to sampling to establish detection limits and sensitivity. Blanks and spikes will be run with each set of samples as part of the Quality Assurance program.

- The California Regional Water Quality Control Board, North Coast Region, fine that:
- 1. The Paelfic Gas and Electric Comany,77 Beale Street, San Francisco, California, 94106 (hereafter the discharger), applied for waste discharge requirements and ,
a permit to discharge wastes under the National Pollutant Discharge Elimination '
System. Waste Discharge Requirements Order No.77-105 (NPDES No. CA0005622) was adopted by the North Coast Regional Board on June 23, 1977. Order No.77-105 expired on June 23,1982, and the discharger submitted
, a Report of Waste Discharge for reissuance of the discharge permit.
- 2. The discharger owns and operates a power plant with three power generating
'utits located on the east shore of Humboldt Bay in the SW 1/4 of Section 8, i T4N, R1W, HB&M as shown on Attachment "A", incorporated herein and made I part of this Order. Units No.1 and No. 2 were constructed in 1956 and 1958 respectively, are driven by fossil fuel and have a gross generating onpaelty of 53 megawatts each. Unit No. 3 was constructed in 1963, is nuclear fueled and has a generating espeelty of 65 megawatts. Unit No. 3 has been shut i down 1976 for seismic studies and NRC backfitting ounditions.
- 3. Waste discharges as described in the Report of Waste Discharge are as foBows:
- a. ~ Surface Water Discharges (All flows are intermittent except cooling water) i Discharge No. 001 - Once Through Coollrr Water Cooling water for steam condensers and other miseeDaneous service cooling systems are pumped from Humboldt Bay via Fisherman's Channel and returned to the Bay through a discharge emnet Design flows are 38 mgd each for Units No.1 and No. 2 and 74 agd for Unit No. 3. Intake temperatures range from 530 F to 590 F and discharge temperatures range from 860 F to 780 F. Studies eonducted by the discharger in 1971 and 1972 reveal that no adverse effect to benefletal uses has resulted from the cooling water Mwge.

- Waters and Enclosed Bays and Estuaries of California. On May 16,1974, the State Water Resources Control Board adopted the Water Quality Control Polley i ,
for the Enclosed Bays and Bstuaries of California. On May 20,1975, the Regional Board adopted the Water Quality Control Plan for the North Coastal ,
l Basin. The Basin Plan was amended on several occasions since 1975. All three i of these Plans contain water quality objectives for Humboldt Bay.
l ;
5.- As enumerated in the Water Quality Control Plan for the North Coastal Basin,
, benefleial uses of Humboldt Bay include:
i i a. Industrial water mapply 1 b. navigation "

fish migration and spawning l ,
- h. -
l l L shenfish harvesting .
- 8. During 1972 and 1973, the Feelfie Oas and Electrie Company conducted an extensive evaluation of the effect of cooling water discharges on the benefielal uses of receiving waters at the Humboldt Bay Power Plant. The field studies
, demonstrated that benefletal uses of receiving waters have not been unreasonably
! affected by the discharge. Operating conditions have changed sinos July 1978
! such that Units No. I and 2 now generate all power at the faculty whereas they ,
- generated only 30 percent of the power during the 1972-73 thermal effect study. I i
Cooling water flows and thermal discharges are different now than when Unit No. 3 was operating during the previous study; therefore, new thermal studies
- she/;.id be conductd to evaluate the effect of present ecoling water discharges on benefletal uses of Humboldt Bay.

Order No. 82-85 !
I nonmunleipal wastewater such as elear brines, washwater, and pool drains are not necessarDy considered industrial process wastes, and may be allowed by Regional Boards wider discharge requirements that provide protection to the beneficial uses of the receiving water. The Board finds that existing discharges from this faculty are treated consistently to a degree that they would be elassified as innocuous nonmunicipal wastewater and that waste discharge !
requirements are suffielent to provide protection to the beneficial uses of l
Humboldt Bay.
- 8. Effluent limitation guidelines for the 8 team Electric Power Generating Point Source Category have been promulgated by the United States Environmental
. Protection Agency (EPA) requiring the ap'lication p of the best practicable control
! technology eurrently avaDahle (BPT). Additional effluent limitation guidelines l
have been proposed, but not promulgated, by the EPA, including effluent limits .
for best avaDable technology economically achievable (BAT) and best conventional pollutant control technology (BCT). Some affluent limitations contained in this Order are derived from the promulgated Pederal guidelines, some from the proposed guidelines, and others are based on the Water Quality Control Plans
, listed in No. 4 above. Together, they are considered the best profoulonal
- Judgment of the Board. Limits are seject to reconsideration when the final j guidelines are promulgated.
0.- The issuance of Waste Discharge Requirements for this discharge is exempt from the provisions of Chapter 3 (commeneing with Section 11100) of Division 13 of
- the Public Resourees Code as set forth in Section 13389 of the Water Code.
l The Regional Board finds that no adverse water quality impacts wD1 result if the discharger complies with the terms of this Order. l l 10. The Board has notified the discharger and interested ageneles and persons of its intent to prescribe waste discharge requirements for the proposed discharge I
and has provided them with an opportunity for a public hearing and an opportunity l to semit their written views and recommendations.
1
!- 1L The Board, in a public meeting, heard and considered au comments pertaining to the discharge.
l l THEREFORE, Fr B HEREBY ORDERED that persuant to the provisins of Division 7 of 4
the Callornia Water Code and regulations adopted thereunder, and to provisions of the i Pederal Water Pollution Control Act as amended, and regulations and guidelines adopted I thereunder, the discharger ahan comply with the foBowing .

A. On May 18, 1972, the State Water Resources Control Board adopted the Eter
! Quality Control Plan for Control of Temperature in the Constal and Interstate
. Waters and Enclosed Boys and Estuaries of California, & May 16, 1974, the State Water Resources Control Board adopted the Water Quality Control Policy for the ]
- Enclosed Boys and Estuaries of California. On May 20, 1975, the Regional Board
- adopted the Water Quality Control Plan for the North Coastal Basin. h Basin i
Plan was amended on several occasions since 1975. All three of these Plans contain weer quality objectives for 1ksaboldt Bay.
l 5. As enumerated in the Water Quality Control Plan for the North Caostal Basin, j beneficial uses of E=haldt Bay include:
I
- a. industrial inter supply
- b. navigation
- c. uter contact and non-contact inter recreation ;
i d. ocean commercial and sport fishing i j e. cold fresheter habitat
- f. wildlife and marine habitat
- g. preservation of rare and endangered species
- h. fish migratim and syswning i 1. ,aba11fi=h harvesting I
- 6. h State Boys and Estuaries Pblicy requires that industrial process water discharges be phased out at the earliest practicable date; ho wver, innocuous j ====ici pal tastewater such as clear brines, washeter, and pool drains are not mar ====rily can=4d. red industrial process testes, and may be allowed by Regional
! Boards eder d4=eh ge requirements that provide protection to the beneficial l uses of the receiving water. The Board finds that existing discharges from this
! facility are treated consistantly to a degree that they would be clammified as i naa=== nousunicipal wastemter and that waste discharge requirements are
} sufficiant to provide pro +=e*4= to the hanaficial uses of Emboldt Bay.
j.'
- 7. Effluent limitation guidelines for the Stamm Electric Pbwer Generating Point
- Source Category have been promulgated by the hited States Ihvironmental
. Protection Agency (EPA) requiring the application of the best practicable control j tarhaalogy currently available (IFI). Additional effluent limitation guidelines i have been proposed, but not promulgated by the EPA, including affluent limits for
, best available +=eh=1 agy , economicallyachievable(BAT),andbestconventianal
! pollutant control technology (BCT). Some affluent limitations contained in this -
l Order are derived from the promulgated Federal guid=14a==, see from the proposed
! suidelines, and others are based on the Water Quality Control Plans listed in No.
I 4 above. Together, they are canaid red the best prof ===4aam1 judgment of the Board. Limita are subject to reconsideration then the final guidelines are Promulgstad.
- 8. The fasuance of waste discharge requirements for this discharge is exempt from the provisions of O mpter 3 (e - ing with Section 2110) of Division 13 of the i Public Resources Code as set forth in Section 13389 of the Eter Code. The i Regional Board finds that no adverse water quality $mpacts will result if the d4=eh=eser complies with the tarus of this Order.
