Attachment A ODCM Revision 1.8 Chapter 10 LaSalle Station Change Summary Revision Index: Removed page revision index. No longer are individual pages revised. The revision index revision number is assigned to the chapter.

Table of Contents: Updated page numbers Added section 10.2.1.2 Page 10-1 Revised wording concerning oil burning to describe the general characteristics of the effluent pathway.

Page 10-4 Removed the application of the pre-treatment monitor setpoint set at or below one-half of the post-treatment monitor. The post-treatment monitor setpoint already has the conservatism factor in its equation. Removed last sentence in the description of Q,. This information is reflected in the general setpoint description.

Page 10-5 Added statement that the post-treatment monitor setpoint is set using the more conservative value from equations 10-3 and 10-4. This reflects current serpoint practice and is conservative. Removed description for efficiency. The efficiency is a given value associated with a monitor, no further information is necessary.

Page 10-6 Added statement for vent stack and standby gas treatment monitors that the setpoint is set using the more conservative value from equations 10-3 and 10-4. This reflects current setpoint practice and is conservative.

-. Page 10-7 Removed specific sources referenced in 10.1.3.4 ,

for vent stack and standby gas treatment l monitors and added statement reflecting current l practices in obtaining conversion factors. This will also support improvements to calibration procedures that are planned.

Page 10-8 Added Cooling Pond Blowdown to the general system description for liquid releases to link its existence to sampling and analyses requirements in Chapter 12. Revised Section 10.2.2.1 to indicate the automatic closure occurs on hi-hi alarm, which is consistent with current plant operation.

Page 10-10 added a description to the 10 multiplier for additional information.

ODCM Revision 1.8 Chapter 11 LaSalle Station Change Summary Revision Index: Removed page revision index. No longer are individual pages revised. The revision index revision number is assigned to the citapter.

Page 11-1 Revised wording to address information in Chapter 11 and removed references to Chapter 9. Chapter 9 is to be deleted.

Page 11-2 Revised requirement for charcoal cartridge collection and analysis to biweekly. A longer collection time makes it easier to meet required LLD's. Also, the required time between sample collection and analyses remains unchanged, and contractor counting procedures integrate the activity from the analyses back to the time of sampling, therefore maintaining the integrity of the analyses.

Deleted air sampler L-12 and replaced it with L-4. It was determined by a scaled measurement on a map, that L-12 is located approximately 9 miles from site which does not qualify it for an indicator location. At the same time, L-4 was determined to be approximately 3.2 miles from site which qualifies it for a far field indicator.

Page 11-3 Added "on each TLD" to the frequency of analysis column for TLD's.

Page 11-4 Revised distances for TLD's 204-1 and 204-2, whose distances were determined by a scaled measurement on a map. Removed asterisk on TLD locations 211-1 and 211-2 which indicated the TLD's were placed in the 4th qtr of 1995. Footnote no longer applicable.

Page 11-6 Removed the word "and" that was inappropriately placed between the words " tritium" and " analysis" for surface water and control analysis.

Page 11-7 Removed the word "or" that was inappropriately placed between " October" and " monthly" in the collection frequency column for milk.

Expanded food product sampling requirements to include samples from each of the 4 major quandrants around the station. Revised collection frequency to annually due to the short growing period and single harvests associated with the area.

Figure 11-1 Deleted location L-12, added location L-4 Figure 11-3 Moved water sample locator 21 into the river.

I Table of Contents: Updated page numbers. Added three new tables, 12.5-1, 12.5-2, 12.5-3. These tables were originally in

Chapter 9.

Page 12-1 Removed reference to Chapter 9. Information relocated to Chapter 12.

Page 12-4 Corrected a typographical error in definition 12.1.0.

Page 12-7 Added information to the footnote that the table frequencies do not apply to REMP. Added footnote for notation "R" that upon Tech. Spec. approval, the notation frequency will change to once per 24 months.

Page 12-9 Added footnote for cooling pond blowdown pipe. Added  ;

unit specific designator for RHR. )

l Page 12-10 Corrected Section and Table references. Added specific analyses requirements for Action 101.

Page 12-11 Broke instrumentation out by Line and Unit.

Renamed River Discharge Blowdown pipe to terminology used by station.

Page 12-14 Inserted double asterisk in section 1. Was originally omitted. Added additional EPN numbers to 2.d and 4.e to indicate another available data point. Corrected an EPN in 2.e.

Page 12-15 Added requirement for WRGM tamples to be analyzed at the LLD's listed in Table 12.4.1-1.

Modified the wording of **** footnote to require monitoring only when effluents are being released instead of during equipment operation since equipment can be operated without a flowpath to the environment.

Re-worded Action 110 to incorporate the NOTE from the l end of the page into this Action number to which it  ;

applies, j Page 12-16 Added the **** footnote to indicate a new requirement.

Page 12-17 Added the ***" footnote to require monitoring only when effluents are being released instead of during equipment operation since equipment can be operated without a flowpath to the environment.

P Page 12-21 Added weekly frequency to continuous release composite for I-131 and principal gamma emitters Indicated that cooling pond blowdown is the system that applies to the continuous release category.

Changed Fe-55 LLD from 1E-5 to 1E-6 to remain consistent with the other nuclear stations.

, Page 12-22,23 Added an alternate LLD philosophy to allow computer generated LLD's to be used.

Page 12-24 Removed the word " continuously" from footnote "c" since the compositor pulls a periodic sample of the effluent stream. Removed reference to " mixing i

in accordance withthe ODCM" from footnote D. The ODCM does not address mixing methods.

3 Page 12-27 Removed the word "or" to lessen confusion on the j actual reqairments for liquid dose projections.

Page 12-28 Added wording to 12.4.1.B.1 so it is consistent

, with the wording of 12.4.1.B.2.

Page 12-30 Removed an incorrect LLD listed for H-3. Revised i frequency for H-3 sampling in section B to 4

weekly since spent fuel is normally always in

the fuel pool. Removed reference to Xe-133 equivalent under the LLD for Noble Gas Monitor. Reworded Section D to clarify requirements.
Page 12-31 Added sampling and analyses requirements for the new oil burning unit.

Page 12-31,32 Added an alternate LLD philosophy to allow j computer generated LLD's to be used. j Page 12-34 Expanded footnote to include a monthly frequency J

for sampling and analysis of H-3 when spent fuel not in the fuel pool.

Page 12-45 to 61 Moved REMP requirements from chapter 9 to section 12.5 and 12.6.1. Made minor modification to the REMP program as it existed in Chapter 9:

Revised ranges to include all sampling locations.

l Expanded food product sampling requirements to include samples from each of the 4 major quandrants around the station. Revised collection frequency to annually due to the short growing period and single harvests associated with the area.

Revised requirement for charcoal cartridge collection and analysis to biweekly. A longer collection time makes it easier to meet required LLD's. Also, the required time between sample collection and analyses remains unchanged, and contractor counting procedures integrate the activity from the analyses back to the time of sampling, therefore maintaining the integrity i of the analyses.
