BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2013 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

GENERAL OVERVIEW/DISCUSSION General Overview/Discussion This report quantifies the radioactive gaseous, liquid, solid radwaste releases, and summarizes the local meteorological data for the period from January 01, 2013 through December 31, 2013. This report has been prepared utilizing the methodology and parameters specified in the calculation of offsite doses resulting from radioactive gaseous and liquid effluents found in Braidwood's Offsite Dose Calculation Manual (ODCM). It has been formatted consistent with Exelon Procedure CY-AA-170-2000 and exceeds the requirements specified in Regulatory Guide 1.21 revision 1, "MEASURING, EVALUATING, AND REPORTING RADIOACTIVITY IN SOLID WASTES AND RELEASES OF RADIOACTIVE MATERIALS IN LIQUID AND GASEOUS EFFLUENTS FROM LIGHT-WATER-COOLED NUCLEAR POWER PLANTS."

The quantity of radioactive material released from Braidwood Nuclear Power Plant was determined from in-house and vendor laboratory analysis of continuous on-line sampling media and batch sample media from all ODCM specified effluent pathways. These pathways include the Unit 1 and 2 Station Vent Stacks, Exelon Pond remediation, Turbine Building Remediation, Vacuum Breaker number one remediation, Condensate Polisher Sump, Waste Water Treatment facility, and Circulating Water Blowdown.

The volume and quantity of radioactive waste shipped offsite from Braidwood Nuclear Power Plant for processing and disposal were determined from data maintained in the radwaste shipping database.

Radwaste processed for shipment was in accordance with Exelon procedure RW-AA-100, "PROCESS CONTROL PROGRAM FOR RADIOACTIVE WASTES" and consistent with the UFSAR.

Meteorological data was obtained from the 320 foot meteorological tower located on the Braidwood Station premises.

Gaseous Effluents Gaseous radioactive releases for the 2013 timeframe are captured in the tables titled, "Summation of All Releases" for Unit 1 and 2, respectively. Radioactive noble gases released for the timeframe totaled 1.25E+00 Curies. Releases of radioiodines and particulates with a half-life greater than eight days totaled 1.07E-03 Curies. Gaseous tritium releases totaled 4.04E+02 Curies. Gaseous C-14 was calculated to total 8.48E+00 Curies. No gross alpha was detected in gaseous effluents.

Noble gases released in gaseous effluents resulted in a maximum total body dose of 2.31 E-05 mrad, with a corresponding skin dose of 1.14E-04 mrad. The release of radioactive particulates, C-14, tritium, and radioiodines in gaseous effluents during the reporting period resulted in a total body dose to the maximally exposed hypothetical individual of 5.47E-01 mrem. The maximum hypothetical dose to any organ from radioactive particulates, C-14, tritium, and radioiodines was 2.27E+00 mrem.

Liquid Effluents Liquid radioactive releases for the 2013 timeframe are captured in the table titled, "Liquid Effluents Supplemental Release Information" and in Appendix C, "Unit Specific Annual Effluent Summaries." One hundred forty-eight liquid batch releases occurred during the reporting period. Additionally, radioactive liquid effluents were continually being released through Circulating Water Blowdown. These discharges contained 4.08E+03 Curies of tritium and 1.60E-01 Curies of fission and activation products. The resultant maximum total body dose was 5.92E-02 mrem, with a corresponding organ dose of 1.61 E-01 mrem.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2013 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

GENERAL OVERVIEW/DISCUSSION 40 CFR190 Compliance The Braidwood ODCM defines the total dose for the uranium fuel cycle as the sum of doses due to radioactivity in airborne and liquid effluents and the doses due to direct radiation from contained sources at the nuclear power station. The total dose, DTo, in the unrestricted area to a member of the public due to plant operations is given by: DTo = DE, + D.Liq2 + DajNNG Where:

DTot Total Dose to Member of Public [mrem]

Total off-site dose to a member of public due to plant operations.

DEx Total External Total Body Dose [mrem]

Total body dose due to external exposure to noble gases, N-16 skyshine and on-site storage facilities.

Dj"Liq Liquid Effluent Dose [mrem]

Dose due to liquid effluents to age group a and organ j. The age group and organ with the highest dose from liquid effluents is used.

DajNaG Non-Noble Gaseous Effluent Dose [mrem]

Dose due to non-noble gaseous effluents to age group a and organ j. The age group and organ with the highest dose from non-noble gas effluents is used.

Exposures measured on the Independent Spent Fuel Storage Installation (ISFSI) and Onsite Steam Generator Storage Facility (OSGSF) dosimeters are statistically indiscernible from natural background. N-16 skyshine is not applicable to Pressurized Water Reactors. The resultant 40CFR190 dose calculated for a member of the public is 2.43E+00 mrem.

GENERAL OVERVIEW/DISCUSSION Meteorological Data The Braidwood Station meteorological monitoring program produced 52,475 hours0.0055 days 0.132 hours 7.853836e-4 weeks 1.807375e-4 months of valid data out of a possible 52,560 parameter hours during 2013 (366 days x 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s/day x 6 measured priority parameters),

which represents an overall data recovery rate of 99.8%. Priority parameters are all parameters except dew point temperature and precipitation. For the year, winds measured at 34 ft. most frequently came from the West-Northwest (8.84%) and fell into the 3.6 - 7.5 mph wind speed class (42.11%). Calms (wind speeds at or below the sensor threshold) were measured 0.05% of the time and speeds greater than 24.5 mph were measured 0.02% of the time. Stability based on the 199 - 30 ft. differential temperature most frequently fell into the neutral classification (39.43%).

The following are the maximum annual calculated cumulative offsite doses resulting from Braidwood airborne releases in 2013 based on concurrent meteorological data:

GENERAL OVERVIEW/DISCUSSION Unit 2 Compliance Status 10 CFR 50 Appendix I Yearly Objective % of Appendix I gamma air 10.0 mrad 0.00E+00 beta air 20.0 mrad 0.OOE+00 whole body 5.0 mrem 4.59E+00 skin 15.0 mrem 0.OOE+00 organ 15.0 mrem 6.11 E+00 (1) Gamma Air Dose - GASPAR II, NUREG-0597 (2) Beta Air Dose - GASPAR II,NUREG-0597 (3) Whole Body Dose - GASPAR II, NUREG-0597 (4) Skin Dose - GASPAR II,NUREG-0597 (5) Inhalation and Food Pathways Dose - GASPAR II, NUREG-0597 Offsite Ambient Radiation Measurements It is estimated that the average radiation dose received by an individual in the United States is about 360 mrem/yr and that nuclear power stations account for less than two parts in a thousand of this radiation.

These figures are based on data in Table 8.1 of NCRP 93. The table includes the following data:

Source Average Individual Dose (mrem/yr)

Natural sources (average in U.S.) 300 Medical (whole-body equivalent) 53 Nuclear fuel cycle 0.05 Other -7 Total About 360 The radiological effects of nuclear power station operation on the environment are characterized as "usually so small that they are masked by normal fluctuations in natural background sources and by the normal uncertainties of the measurement process." Review of the Braidwood Optically Stimulated Luminescent Dosimetry (OSLD) data yielded no measurable increase above the normal fluctuation in natural background levels.

Radioactive Solid Waste Disposal Radioactive wastes shipped offsite are captured in the table titled, "Solid Wastes Shipped Offsite for Burial or Disposal (Not irradiated fuel)." Approximately 1.54E+03 cubic meters of solid waste were shipped offsite containing approximately 7.43E+02 Curies during the 2013 reporting period.

2. Effluent Concentration Limits

a. Fission and Activation Gases: 10CFR20 Appendix B Table 2

b. Iodine: 10CFR20 Appendix B Table 2

c. Particulates: 10CFR20 Appendix B Table 2

d. Liquid Effluents: 10 X 10CFR20 Appendix B Table 2

3. Average Energy The ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/yr to the total body, and less than or equal to 3,000 mrem/yr to the skin. Therefore, the average beta and gamma energies (E) for gaseous effluents as described in Regulatory Guide 1.21 are not applicable.

4. Measurements and Approximations of Total Radioactivity

a. Fission and activation gases:

Before being discharged, containment batch releases are analyzed for noble gas and tritium via gamma spectroscopy and liquid scintillation, respectively. Gaseous decay tanks are analyzed for noble gases before being discharged via gamma spectroscopy. Released activity is normally calculated using volume of release, which is determined by change in tank or containment pressure.

The Auxiliary Building ventilation exhaust system is continually monitored for radioiodines and particulates. These samples are pulled every seven days and analyzed via gamma spectroscopy.

Noble gas samples are pulled and analyzed weekly by gamma spectroscopy. The average flow at the release points and nuclide specific activity concentrations are used to calculate the activity released.

Volumes and activities of effluents discharged from systems that are common to both units are divided between both units.

The secondary side of both units contain tritium. Very small amounts of tritium are continually released to the atmosphere from secondary components through packing leaks, tank vents, the main condenser, etc. Bounding calculations have been performed to show that very large leaks (1000 gpd) for extended periods (1 month) at normal secondary tritium concentrations, would provide an insignificant increase (1.OOE-5 mrem) in offsite dose.

b. lodines:

Radioiodines in the Auxiliary Building ventilation exhaust system are continually being collected via activated charcoal cartridges in the diverted sample process flow. The iodine cartridges are pulled weekly and analyzed via gamma spectroscopy. Radioiodine concentrations greater than the LLD are multiplied by the volume of air discharged during the sampling timeframe.

Radioiodines are analyzed in liquid effluent streams through performance of batch release tank grab samples and weekly liquid effluent composite samples. The analyses are performed via gamma spectroscopy.

Volumes and activities of effluents discharged from systems that are common to both units are divided between both units. Effluents that are unit specific are assigned to the appropriate unit.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2013 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

c. Particulates, half-lives > 8 days:

Particulates in the Auxiliary Building ventilation exhaust system are continually being collected via filter media in the diverted sample process flow. Particulate filter media are pulled weekly and analyzed via gamma spectroscopy. Particulate concentrations greater than LLD are multiplied by the volume of air discharged during the sampling timeframe. A composite sample is created from 3 month's particulate sample media for Sr-89/90, Fe-55, and gross alpha analysis by an offsite vendor. The vendor supplied data are utilized in conjunction with the volume of air released through the Auxiliary Building ventilation to quantify Sr-89/90, Fe-55, and gross alpha releases.

Volumes and activities of effluents discharged from systems that are common to both units are divided between both units. Effluents that are unit specific are assigned to the appropriate unit.

d. Liquid effluents:

Liquid effluents are categorized as either batch release or continuous release. All liquid releases are analyzed for principal gamma emitters, radioiodines, dissolved and entrained gases, gross alpha, and tritium onsite via gamma spectroscopy, gas flow proportional counting, or liquid scintillation, as appropriate. An offsite laboratory analyzes liquid composites for Sr-89/90 and Fe-55. Vendor results are applied to the applicable volume of liquids discharged during the timeframe. Volumes and activities of effluents discharged from systems or locations are divided between both units.

e. Gross alpha Gross alpha is analyzed in both the gaseous and liquid effluent pathways. Weekly gaseous particulate media is composited for offsite vendor analysis. Gross alpha activity greater than vendor LLD values are assigned to the applicable timeframe and gaseous volume released.

Liquid effluent gross alpha analysis is performed through compositing monthly discharges and gas flow proportional counting.

f. Carbon-14 Carbon-14 is assessed for continuous gaseous effluents through the use of Electric Power Research Institute's (EPRI) industry accepted production mechanism and production rate study 1021106. C-14 production is a function of each unit's full power operation and gaseous volume released. C-14 is not evaluated through laboratory sample analysis.

g. Estimated Total Error Present Estimated total error is calculated periodically and communicated as part of the Effluent and Waste Disposal Summaries.

h. Less than the lower limit of detection (<LLD)

Samples are analyzed such that the Offsite Dose Calculation Manual (ODCM) LLD requirements are met. When a nuclide is not detected during the quarter then <LLD is reported.

7. ODCM Revisions The ODCM was revised in 2013 in order to adopt Reg Guide 1.23 revision 1. The change was made in order to adopt Reg Guide 1.23 revision 1 MET tower instrument calibration accuracies as they better reflect current regulatory requirements and best practices. Adoption of Reg Guide 1.23 revision 1 has no impact on the control of effluents or their quantification. Reducing the calibration accuracy of the MET tower's dew point instruments from +/- 0.5 degrees Celsius to +/- 1.5 degrees Celsius will not impact offsite dose to the public as dew point is not a variable in offsite dose calculations. The atmospheric moisture measurements were required to assess the physical and aesthetic impacts of increased water vapors during initial plant citing. The adoption of Reg Guide 1.23 revision 1 requires wind speed system accuracy to be +/- 0.45 mph or 5% of observed wind speed. The wind speed accuracy change is reflective of wind speed system limitations and is an enhancement to the established criteria as it is difficult to calibrate the wind speed instruments to +/-

0.5 mph at very high wind speeds. Revision 8 of the ODCM is being submitted concurrently with this Annual Radioactive Effluent Release Report on a CD as a searchable .PDF due to the size of the document.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2013 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

Instrument Issues On 2/4/13, it was found that the Waste Water Treatment ODCM compositor was not functional when the Chemistry Technician arrived at the sample location to collect the weekly composite sample. The Ground Fault Circuit Interrupter had tripped at some point during the week. The Waste Water Treatment compositor was last observed to be operational during Chemistry rounds on 1/31/13. The Ground Fault Circuit Interrupter was reset and the compositor was verified to be operational. There were approximately two liters of water in the composite jug for analysis, however, there was not as much water as typically expected from a week's operation. This issue was entered into the Corrective Action Program as IR 1471548.

On 4/15/13, the ODCM Exelon Pond compositor did not contain the needed two liters of sample to perform the weekly and monthly analysis. The flow totalizer indicated 6,910,205 gallons of Exelon Pond water remediation to Circulating Water Blowdown. The lack of sample was caused by fouling of the solenoid actuated sampling valve. Water from the Exelon Pond had been trending less than 200 pCi/L tritium for the entirety of 2013 as monitored for RGPP. Additionally, remediated Exelon Pond water was composited downstream as part of Circulating Water Blowdown. This issue was entered into the Corrective Action Program as IR 1502199.

On 4/22/13, the ODCM Exelon Pond compositor did not have the needed two liters of sample to perform the weekly and monthly analysis. The flow totalizer indicated 303,658 gallons of Exelon Pond water remediation to Circulating Water Blowdown. The lack of sample was caused by fouling of the solenoid actuated sampling valve. Water from the Exelon Pond had been trending less than 200 pCi/L tritium for the entirety of 2013 as monitored for RGPP. Additionally, remediated Exelon Pond water was composited downstream as part of Circulating Water Blowdown. This issue was entered into the Corrective Action Program as IR 1505176.

On 10/12/13, a Chemistry Technician found the Condensate Polisher Sump compositor not functioning as designed. A screw attaching the peristaltic pump's cam had backed out resulting in the motor's shaft spinning without engaging the cam. The screw was tightened and the peristaltic tubing replaced. The flow totalizer indicated 31 gallons of Condensate Polisher Sump water having been discharged to the cooling lake prior to the issue's discovery. Following the pump's repair, enough sample was obtained for the weekly composite taken on 10/14/13. Tritium activity discharged to the cooling lake was accounted correctly as the flow totalizer equipment was operable and tritium composite samples were obtained as needed. This issue was entered into the Corrective Action Program as IR 1571295.

On 11/06/2013, it was discovered that a particulate filter paper was missing for the Unit 1 station vent stack 1PR28J skid. The timeframe that the missed sample covered was 7/24/13 11:25 to 7/31/13 11:42. Review of the gamma spectroscopy report from the analysis of the missing sample revealed that particulate nuclides were all less than the LLD. At some point after the sample was counted in the Braidwood count room, the sample was lost or discarded. The missing sample was not a part of the 3rd quarter composite sent to Teledyne Brown for difficult to measure analysis. The missing sample represented 7.6% of the quarter's timeframe for which difficult to measure analysis was not able to be performed. Vendor results for all required difficult to measure nuclides for the 3rd quarter were less than MDC. This issue was entered into the Corrective Action Program as IR 1581875.

During liquid release L-13-140, the 0PR01J liquid release tank process radiation monitor went into high alarm. The alarm resulted in the process radiation monitor going into interlock and securing the liquid release. OPRO1J was declared inoperable and RETS 2.1-1a was initiated. The release was terminated with approximately 7,500 gallons having been discharged. Liquid release tank radionuclide concentrations were consistent with typical batch release tank concentrations. Liquid effluent concentration limits were not challenged during the release. The setpoints requested by Rad Protection allowed the process radiation monitor to be in the ALERT range prior to the release start.

The process radiation monitor was decontaminated in order to declare the instrument operable. This issue was entered into the Corrective Action Program as IR 1575565.

On 1/7/14, it was discovered that the final totalizer reading for the Vacuum Breaker #1 remediation pump was not displaying a correct value. Remediation of the Exelon Pond had not occurred during the 12/31/13 thru 1/7/14 timeframe, yet the totalizer displayed a value that would indicate -57 gallons had been remediated. It is anticipated that the cold winter weather and stagnant water in the piping resulted in the erroneous flow totalizer reading. This issue was entered into the Corrective Action Program as IR 1604964.

Abnormal Release On July 2, 2013, during the performance of BwOP GS-5, Transferring Gland Sealing Steam (GS) to Unit Supply, 2GS04M, U-2 Gland Steam Rupture Disk ruptured while performing step F.5, 'Fully OPEN 2MS1 67',

Main Steam Supply Isolation to Gland Steam (Ref. 1). Initially GS was being supplied by Auxiliary Steam via the Pressure Regulating valve and 2GS004 'Supply valve Bypass' valve, which was full open in the MCR to maintain 80-125 psig on 2PI-GS001. Local Operators heard a bang and re-closed 2MS167. After closing 2MS167, 2PI-GS001 indicated 30 psig in the Unit 2 GS header.

The Chemistry Department has been tasked with reviewing this event for reporting in the Annual Radioactive Effluent Release Report (Ref. 2). As such, an estimate of the quantity of tritium laden water released during the event was needed. The System Manager has indicated that there are no secondary system inventory indications that can be used for estimating total water release during the event. As such, this Engineering Technical Evaluation will develop estimates for steam flow rates to be used by the Chemistry Department for the Annual Release Report.

Detailed Evaluation Issue Reports 1531951 and 1557942 provide information on the event that can be used to determine two steam flow rates.

The first phase of the event can be taken at the time of rupture disc opening when the GS header pressure is assumed to be 500 psig.

" The second phase of the event will be evaluated after 2MS167 was closed resulting in a reported GS header pressure of 30 psig.

To determine the steam flow rates through the GS rupture disc exhaust piping, equations for compressible flow (Darcy Equation) from Reference 3 will be used. This requires an understanding of the piping configuration. There are no known as-built isometric drawings for the 2GS04B-6" pipe. The following is an outline of the piping routing from the 2GS04M to the exhaust point on the turbine building roof based on a plant walkdown and a review of the available Gland Steam Isometric Drawing (ref. 5). The piping run described below is visible from the 426' elevation of the turbine building.

o 2GS04M is located at J.2-25.2 at 426' elevation, plus 15' o Pipe 2GS04B-6" leaves 2GS04M vertically and turns North to J.2-24 o At J.2-24, the exhaust header turns West to E-24 o At E-24, the exhaust header turns South (through a number of 45 degree bends) o At E-28, the exhaust header turns vertical through an abrupt enlargement to exhaust out 2G$59A-10"

" In the exhaust path, there are a total of

" Nine 90 degree bends (R/D = 1.5)

" Nine 45 degree bends (R/D = 1.5)

" One gradual enlargement (approx 45 degrees) from 4" to 6"

" One sudden enlargement from 6" to 10"

" Based on referenced structural drawings, there is approximately 200 feet of 6" pipe between 2GS04M and the vertical exhaust.

" There is approximately 14 feet of 10" exhaust pipe at the turbine building roof 135 of 174

Evaluation of Pipe Resistance Coefficients To estimate the steam flow rate, the flow is assumed to be in complete turbulence. This assumption will be validated at the end of this evaluation. The assumption of complete turbulence permits the use of standard pipe and fitting resistance values. The resistance values will be based on flow in 6" pipe, therefore; the K-values will be adjusted to 6" pipe values using the applicable fG factor.

0f Conclusions/Findings This evaluation has computed the flow rates under two separate operating conditions corresponding to the time the 2MS167 valve was open and closed. With the valve open, it was assumed that the GS header pressure was 500 psig. This is conservative since the rupture disc fails at 500 psig and opening of the rupture disc exhaust path will result in a significant reduction in GS header pressure. Since the magnitude of this reduction in unknown the flow rate is estimated assuming constant header pressure which will produce a conservatively high flow rate. The second flow rate was estimated based on the Issue Report documented GS header pressure of 30 psig.

To determine the total volume of water released during the event, the operating time in each of the two operating regimes must be used as follows.

Station personnel observations, the referenced Issue Reports, and the engineering analysis provided the basis for bounding the radionuclide activities and calculated dose. Once the 2GS04M ruptured, the system went from 500 psig to 30 psig within one minute and remained at that pressure for approximately 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

8,555.9 cubic feet of water was released as steam based on the bounding criteria. The tritium concentration of the secondary system at the time of issue occurrence was 61,100 pCi/L. Abnormal release permit 2013372 was created to document the abnormal release and has been included for reference. The dose associated with the abnormal release is contained within the quarterly and annual running dose for all gaseous releases.

BRAIDWOOD NUCLEAR POWER STATION RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2013 UNIT 1 AND 2 (Docket Numbers 50-456 and 50-457)

Braidwood Station's Process Control Program (PCP) is managed via procedure RW-AA-100, "Process Control Program for Radioactive Wastes." The purpose of the PCP is threefold;

1) Establish the process and boundary conditions for the preparation of specific procedures for processing, sampling, analysis, packaging, storage, and shipment of solid radwaste in accordance with local, state, and federal requirements.

2) Establish parameters which will provide reasonable assurance that all Low Level Radioactive Wastes (LLRW), processed by the in-plant waste process systems on-site OR by on-site vendor supplied waste processing systems, meet the acceptance criteria to a Licensed Burial Facility, as required by 10CFR Part 20, 10CFR Part 61, 10CFR Part 71, 49CFR Parts 171-172, "Technical Position on Waste Form (Revision 1)"

[1/91], "Low-Level Waste Licensing Branch Technical Position on Radioactive Waste Classification" [5/83],

and the Station Technical Specifications, as applicable.

3) Provide reasonable assurance that waste placed in "on-site storage" meets the requirements as addressed within the Safety Analysis Reports for the low level radwaste storage facilities for dry and/or processed wet waste.

There were no revisions to RW-AA-100 in 2013.

While not directly controlled by RW-AA-100, liquid radwaste processing is discussed on a minimal basis.

UFSAR changes DRP 12-015 and DRP 13-064 discuss inclusion of an onsite 500,000 gallon tank, the OWX27T, to store processed liquid radwaste and installation of a hose to connect the tank to the liquid radwaste process piping. When Radwaste Monitor Tank tritium concentrations exceed 1.OOE+00 uCi/cc, the water is processed through a series of demineralizers and reverse osmosis membranes to attain Reactor Coolant System (RCS) purity; however, the water is stored in the OWX27T versus transfer to the Primary Water Storage Tanks (PWST). The storage of water with concentrations above 1.OOE+00 uCi/cc provides the station the flexibility to release the water, at their discretion, via normal liquid release tank pathways and help drive down the RCS tritium concentration by not recycling back to the PWSTs. The hose that was installed via EC 396325 and DRP 13-064 in 2013 has allowed the station to begin releasing the OWX27T water per the established radwaste processing and release procedures. Releases from the OWX27T are in progress and in accordance with 10CFR20 Appendix B, Table 2 effluent release criteria.
