(1) You state "any effluent monitor" then list several of them, are there any other effluent monitors at your site?
(2) You state "two times the alarm setpoint" then give values for each effluent monitor. Is this two times this value or is this value already the product of 2 times the alarm setpoint? (Farley & Vogtle only)
RU1 X X X (3) RU1.1: Why are there no setpoint values provided? (Hatch only)
(4) RU1.2: You deleted this EAL stating you do not have radiation monitoring. This is considered a DEVIATION and must be justified more. Explain why your KAMAN monitors won't work for this EAL.
(Hatch only)
(5) The EAL Basis has information related to EAL #4 which you deleted (Farley only).
(1) RU2.1a - Seems to be missing the words "as indicated by the following:"
2 RU2 X X X (2) Logic in the Threshold Values should be "1 OR 2".
(3) Escalation criteria removed from EAL Basis. This was not flagged or justified and should not be removed (1) You state "any effluent monitor" then list several of them, are there any other effluent monitors at your site?
(2) You state "200 times the alarm setpolnt" then give values for each effluent monitor. Is this two times this value or is this value already the product of 200 times the alarm setpoint? (Farley &Vogtle only)

(Hatch only)
(5) The EAL Basis has information related to EAL #4 which you deleted. (Farley & Vogtle only)
(6) Basis states that RAI.1 values are 100 times that of RU1, this is not entirely correct. (Farley only).
(1) You added "UNPLANNED" to RA2.1 and the EAL Basis. This is not flagged, justified, or appropriate.
4 RA2 X X X (2) Do the stated instruments have more than one alarm (i.e., downscale, low, high, etc.)? Which alarm are you referring to?
(1) You added "UNPLANNED" to the threshold wording. This is not flagged, justified, or appropriate.
5 RA3 X X X (2) What about CAS, SAS or the Rad Waste Control Room (if applicable) for areas of concern for RA3.1?
(1) You deleted guidance related to state decisions regarding the calculation of child thyroid CDE without 6 RS1 X X X flagging the omission or justifying the change.

(1) You are referencing EAL #4 even though you deleted it. (Farley & VogIte only)
(2) You deleted "all" from potential release pathways for EAL #1 In the EAL Basis. Are there any other 7 RGI X X X potential release pathways? This was not flagged or justified. (Farley only)
(3) You deleted guidance related to state decisions regarding the calculation of child thyroid CDE without flagging the omission or justifying the change.
8 CUl X(1) You added a statement to the EAL Basis regarding mode dependency. Why?
(2) The title you gave for CA1 is wrong.

9 CU2 X X X (2) Any other indications of possible loss, like tanks? Farley had much more for this EAL threshold. (Vogtle only).
(3) CU2.1: Your EAL threshold states 194' but the EAL Basis states 129'. Correct this error. (Vogtle only).
10 CU3 X X X Do you have the ability to cross-tie? If so, reflect that in this EAL.
(1) Title is different between Justification Matrix and Redline Strikeout copy. Which one is correct?
11 CU4 X X X (2) You deleted the "for greater than 30-min" criteria from the EAL Basis without flagging the change or providing justification. (Farley & Hatch only)
(1) Title is different between Justification Matrix and Redline Strikeout copy. Which one is correct?
(2) CU5.1: Need something here, or need to justify its exclusion better. You must come up with an acceptable alternative. (Farley only)
(3) CU5.1: Where did 60-minute criteria come from and how were these values obtained? (Vogtle & Hatch only).
(4) CU5.2: Is this applicable in these Op Modes?
(1) CU6.1: Justify these communication methods as viable, routine communication methods, particularly the 13 CU6 Xplant radio system and sound-powered phones.

14 CU7 X X X You deleted "required" from CU7.1 b without justification. Why is this deleted?
15 CU8 X jDo not see why you need to delete "observed on nuclear instrumentation".
I as consistency with NEI 99-01 should be the goal.

You also state "any listed systems", what listed systems? (Farley only) 45 HAl X X x (3) HA1.5: Your justification for deleting this EAL does not account for the potential industrial safety hazards (e.g., electric shock) that preclude actions necessary to operate or monitor safety equipment. Provide more justification or re-instate EAL. (Farley &Vogtle only)
(4) HA1.6: What wind speed are you intending this to be declared at? (Farley &Vogtle only) Also, provide more justification as to why you did not develop EALs for other situations covered by this EAL as stated in NEI 99-01.

(1) SU6.1: Justify these communication methods as viable, routine communication methods, particularly the X X plant radio system and sound-powered phones.
(2) SU6.2: Justify these communication methods as viable, routine communication methods. Your "commercial phones" list is too general, provide specific communication methods.

X (2) You deleted referenced examples of other EALs (area, process, and/or effluent rad monitors). This change was not flagged as a difference or deviation and was not justified. Why was this change made? Statement should stay as proposed by NEI 99-01 unless you can make a convincing argument otherwise.

Explain in more detail the rationale for deleting the 15-min criteria. Why was this change made? Statement 63 SS3 should stay as proposed by NEI 99-01 unless you can make a convincing argument otherwise.
(1) You added a note without justification that seems to provide exclusion criteria without justification. Provide 64 SS4 X X adequate justification or remove note. (Farley only)
(1) SS6.1a: The EAL threshold is based upon a loss of approximately 75% of the safety system annunciators, not greater than 75%. Correct this error. Also, you added "or indicators" without justification, why was this added? (Farley only)
(2) The logic could be perceived wrong for this EAL the way you have it worded. The way you have it worded 65 SS6 X X X you would declare a site area emergency if you lose the ability to monitor a significant transient in progress regardless whether or not a significant transient was occurring. Either go back to NEI 99-01 wording, or state "Significant transient in progress AND 1. {loss of annunciation threshold) AND 2. {loss of compensatory non-alarming indications threshold) and 3. {loss of critical safety function monitoring threshold)".
