Procedure Numbe I3 2ogtle Page Number 3 of 34 Rev 20 2.3.1 With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, the contents of the tank (s) may be released to the environment for up to 14 days provided that prior to initiating the release:

a. At least two independent samples of the tank's contents are analyzed, and
b. At least two technically qualified members of the Facility Staff independently verify the discharge line valving, and verify the release rate calculations.

Otherwise, suspend release of radioactive effluents via this pathway.

2.4 The appropriate gaseous effluent monitor ](2) RE-12442-C or 1(2) RE-12444-C, [Plant vents] and 1(2) RE-12839-C, [Condenser Air Ejector and Steam Packing Exhaust] shall be operable during continuous releases via that pathway. If inoperable, perform the appropriate ODCM Action Statement(s).

2.5 The flow rate of the release shall be monitored continuously during the release. If the flow monitor is inoperable, an estimate of the release flow rate shall be determined and recorded at least once per 4 hrs during actual releases per the appropriate ODCM Action Statement(s).

2.6 Prior to release of any batch of radioactive gas, at a minimum, a representative sample shall be obtained and analyzed as required to meet the specifications of 10CFR 20 and 10CFR 50 Appendix I as well as the requirements of the ODCM. A waste gas tank release permit is valid as long as no radioactive gas has been added to the tank since the sample was taken. Tritium is not required for waste gas decay tank releases.

2.7 The more restrictive 31 day dose projection limits for Gaseous Effluents, specified in ODCM Section 3.1.5, are utilized in the EMS Gaseous Release Computer Software AT ALL TIMES. If notified by the Operations Department that a Ventilation Exhaust Treatment System and/or Gaseous Waste Processing System is not being fully utilized, ensure that "LIMITS EXCEEDED" field on the terminal screen says "NONE" and that Section V of the permit indicates the release meets all technical specification criteria.

2.8 Table 3-3 of the ODCM provides sampling and MDC requirements for Gaseous Effluent samples. Containment atmosphere samples require principal gamma emitters to meet an MDC of 1 x 10-4 pci/cc. Sample collection required for permitting of containment purges has been defined as a particulate filter followed by a 4 liter gas marinelli to obtain noble gas sample. When processing the permit, use the noble gas sample obtained.

Date Approved RADIOACTIVE GASEOUS EFFLUENT RELEASE PERMIT Page Number 02/02/2005 GENERATION AND DATA CONTROL COMPUTER METHOD I d of 2.9 While using the EMS software, informational prompts may occasionally occur.

Respond to these prompts accordingly.

2.10 For administrative convenience, for pre-release it is preferred to use a discharge flow rate of 18,000 scfm for all containment purge or vent permits. This discharge rate adequately covers a maxipurge (24 inch valves open), a minipurge (14 inch valves open) and vents (with or without exhaust fans). It is permissible to use flow rates specific for the event planned, but separate permitting of purges and vents shall be required in this case.

2.11 The more restrictive 31 day dose projection limits for Gaseous Effluents, specified in ODCM Section 3.1.5, are utilized in the EMS Gaseous Release Computer Software AT ALL TIMES. If the computer indicates these more restrictive limits will be exceeded for a particular release, Chemistry Supervision may evaluate the proposed release as follows:

2.11.1 Contact Operations Department and VERIFY that the Ventilation Exhaust Treatment System or Gaseous Waste Processing System, (associated with the particular release point being permitted), is OPERABLE per ODCM Section 3.1.5 This will allow using the higher (less restrictive) quarterly and annual dose limits of ODCM 3.1.3 and 3. 1.4.

Allr2.11.2 VERIFY that the proposed release does not exceed the dose limits of ODCM 3.1.3 and 3.1.4.

2.11.3 Utilizing the appropriate password, override the "PERMIT LIMITS EXCEEDED".

Continue processing the permit.

2.11.4 Document the verification of appropriate Gaseous Waste Treatment System Operable per ODCM Section 3.1.5 and verification that the proposed release will not exceed the dose limits of ODCM Section 3.1.3 and 3.1.4 on Section V of the Release Permit.

2.11.5 Attach copies of the sample data to the permit.

2.12 The gaseous effluent monitor ARE-16980A shall be operable during releases via this pathway. If inoperable, perform the appropriate ODCM Action Statement(s).

GENERATION AND DATA CONTROL COMPUTER METHOD 3.0 PREREOUISITES 3.1 The process and effluent radiation monitoring system (PERMS) shall be operable and the appropriate monitor setpoint established per the requirements of the ODCM prior to release of radioactive gases or the requirements of applicable ODCM action statements must be met.

3.2 The Count room Analysis system should be operational with the effluent management system (EMS) software and database current to the release in question. Hand-calculated release permits per 36021-C are allowed if the computer is inoperable.

3.3 Prior to preparing a gaseous release permit, refer to 30025-C for sampling and analysis of batch and continuous sample requirements.

3.4 Verify the tritium in the concentration table is the most current for the release point that a release permit is being prepared for. Edit as needed.

4.0 PROCEDURE 4.1 RESPONSIBILITIES 4.1.1 The Chemistry Department has the lead responsibility for evaluating effluent gas releases, preparing radioactive gas release permits, maintaining effluent release data, and preparing the Annual effluent release reports. The Chemistry Department is responsible for:

4.1.1.1 Completing Section 1, II, 1m, and IV of the gaseous release permit (GRP) and verifying the data by performing a technical review and signing Section V.

4.1.1.2 Updating the GRP after completion of the release by operations and distributing necessary copies.

4.1.1.3 Maintaining effluent records to ensure documentation of monitoring and surveillance results performed in accordance with ODCM.

4.1.1.4 Compiling effluent release data for submission annually.

4.1.1.5 Maintaining a log of all gaseous release permits issued by listing them on Data Sheet 1, "Gaseous radioactive waste permit log".

4.1.2.2 Returning the containment purge or vent release permits to the Chemistry department after completion is the responsibility of both Chemistry and Operations.

4.1.3 Effluent Management System (EMS) Software Overview 4.1.3.1 Prior to the release of potentially radioactive effluents from a power plant into the surrounding air, detailed analyses and calculations must be made to ensure that such effluent releases are within the acceptable limits of safety as specified by NRC regulations.

4.1.3.2 A major function of EMS is the generation of Release Permits, through which the potential radiological impact of individual releases may be determined. Release permits are of two types:

a. Pre-release permits, which determine whether the proposed release can be accomplished within regulatory limits, and
b. Post-release permits, which document the actual release circumstances, the radionuclide concentrations, and the radiological impacts.

4.1.3.3 The main sources of regulations affecting effluent releases are as follows:

a. 10 CFR Part 20, which governs the rate of effluent release through the plant's gaseous discharge points.
b. 10 CFR Part 50 Appendix I, which specifies the maximum permissible dose (both quarterly and annually) to a hypothetical individual who could be exposed to radiation as the result of effluent releases.
c. Offsite Dose Calculation Manual, which governs the dose projections (31 days) and limits for the proposed releases.
d. Reg. Guide 1.21, which governs the reporting of radioactive effluent release data.

4.9 UNPLANNED RELEASES 4.9.1 Unplanned releases could occur through improper valve lineup of the gaseous waste management system, by pipe breakage, equipment leakage, or tank overpressure. Each incident should be treated on a case-by-case basis. The following steps provide guidelines for processing the release:

4.9.1.1 When the unplanned release is discovered or when notified that the unplanned release is occurring; STOP the release via the unplanned pathway if possible.

4.9.1.2 If possible, a sample should be obtained from the release source for particulate, radioiodine, noble gas, and tritium. The events leading up to the loss of gas via the unplanned pathway should be investigated to determine the nature and source of the leak.

4.9.1.3 An estimated release volume should be made based on changes in the source tank pressure, pump design flow information, piping system design, estimated release time/duration, etc.

4.9.1.4 If a PERMS monitor was involved, monitor readings or historical data files should be examined and correlated to known controlled release data for additional information.

4.9.1.5 The meteorological tower data should be retrieved and utilized in conjunction with any other related information.

4.9.1.6 The IPC computer, plant computer and operations logs can also be used to gather data required to quantify the release.

4.9.1.7 Process the release as a batch gaseous release by performing the appropriate steps of Section 4.3 of this procedure. Use release point #27 or #28 "Undefined misc gas release".

This information can be input manually to the concentrations table or old sample data can be called in to be used. This process requires special permission/password privileges to perform. Contact chemistry supervision prior to proceeding.

4.9.2 It is conceivable that a gaseous release may occur and not pass a monitor or no sample is available. Under these conditions, estimates based on experience should be made for uCi/cc and so stated.

4.10 40CFR 190 CALCULATIONS 4.10.1 If twice the limits of ODCM 2.1.3, 3.1.3 and 3.1.4, have been exceeded, fill out the appropriate sections of Data Sheet 3, to determine if the limits of 40CFR 190 have been approached or exceeded. Compliance with the above limits is considered adequate to ensure compliance with 40CFR 190, per the requirements of ODCM Section 5.1.

4.10.2 If the limits of 40CFR 190 are being approached, it may be necessary to perform more frequent calculations to assure these limits are not exceeded.

4.10.3 In addition to Data Sheet 3, it may be necessary to calculate reportable quantities per 40CFR 302 and 355. See Procedure 36015-C for more details on what to do to meet 40CFR 302 and 355 and when this needs to be done.
