Qg l

For answer to Porter County Chapter Intervenors' (PCCI)

'Ihird Set of Interrogatories, Northern Indiana Public Service Company (NIPSCO) states as follows:

1. Please state the present elevation of the lowest point of the Bailly excavation, expressing such elevation in terms of both true elevation and station elevation.

ANSWER: The present elevation of the lowest point of the Bailly excavation is approximately plus 8 feet station datum.

NIPSCO does not understand the term "true elevation".

2. Has there ever been any dewatering (including any diversion
of groundwater by drains or pumps of any kind) at the fossil fuel generating plants at the Bailly Generating Station site?

If your answer is yes, please state:

(a) The date (t ) such dewatering commenced; 03 b

(b) The date(s) such dewatering terminated; (c) The volume of water removed; /

, (d) The present rate of dewatering; and

, 8108240029 810818

'DR ADOCK 05000367 G PDR

(e) The purpose of the dewatering.

ANSWER: Yes, dewatering has occurred at the fossil fuel generating stations at the Bailly site. For the purposes of this response, NIPSCO interprets " fossil fuel generating station" to mean the main building housing the boiler and turbines for Units 7 & 8.

(a) NIPSCO does not know the precise date that construction dewatering for Unit 7 commenced however it was sometime in 1960. Unit 8 construction dewatering began in October 1965. Dewatering for construction of the Unit 7 miscellaneous sump began in January 1977. The gravity drains installed around the foundations of Units 7 & 8 became oper-ational when the backfilling operations reached an elevation such that groundwater levels rose above the drains which was approximately one year after commencement of construction devatering.

t (b) NIPSCO does not know the date that construction dewatering for either Units 7 or 8 was terminated.

l Dewatering for the Unit 7 miscellaneous sump was completed in August 1977. The gravity drains are still in service.

(c) NIPSCO does not know what volume of water was removed during the construction of Units 7 & 8 or during the operation of the gravity drain.

The dewatering system for the Unit 7 miscellaneous sump removed 80,776,800 gallons.

I l

-2A-(d) The present rate of dewatering for the Unit 7, Unit 8 and Unit 7 miscellaneous sump construction is zero. NIPSCO does not know the present rate of dewatering of the gravity drains.

(e) The Unit 7, Unit 8 and Unit 7 miscellaneous sump construction dewatering systems were installed and operated to maintain a dry excavation in which construction could proceed. The gravity drains were installed to prevent seepage of groundwater into Units 7 & 8.

3. (a) Please state all assumptions concerning the status of NIPSCO's fly ash ponds which you contend were included in each of the following:

(i) " Soil Parameters Used in USGS Report 78-138,"

D'Appolonia Consulting Engineers, May 1980; (ii) " Assessment of the Influence of Dewatering at Bailly N-1," D'Appolonia Consulting Engineers, November 1980; (iii) " Effects of Seepage from Fly-Ash Settling Ponds and Constrt!ction Dewatering on Ground-Water Levels in the Cowles Unit, Indiana Dunes National Lakeshore," Indiana, USGS78-138, January 1979.

(iv) " Reassessment of the Effects of Construction Dewatering on Ground-Water Levels in the Cowles Unit, Indiana Dunes National Lakeshore, Indiana," USGS 80-1105, September 1980; and (v) The decision of the Atomic Safety and Licensing Board authorizing issuance of the construction permit for Bailly N-1.

(b) Please provide the bases for each of the responses to Interrogatories 3(a) (i) through 3 (a) (v) .

ANSWER: NIPSCO makes no contentions regarding accumptions contained in the identified reports. However, the assumptions regarding the fly ash ponds which were utilized in preparation of the identified reports are as follows:

(a) (i) In preparation of the May, 1980 D'Appolonia report, groundwatcr drawdown estimates were based on *he assumption of the Bailly N-1 1

1 dewatering and depressurization programs as the only source of drawdown.

(ii) As the title of the November, 1980 D'Appolonia report .mplies, the sole source of drawdown considered in this report was ' he Bailly N-1 dewatering and depressurization programs.

It was assumed that lining of the settling bacins would be completed and thus that the basins would have no further effects on the groundwater regime.

(iii) Tne studies discussed in this report assume ,

that either the settling basins are not sealed or the basins have been sealed and the ground-water mound is declining.

(iv) The studies discussed in this report assume that the ash ponds are sealed and that the groundwater mound is declining.

(v) The Atomic Safety and Licensing Board in its Initial Dccision for the Construction i Permit Hearing relied on calculations which 1

ignored the effects of the ash ponds on ground-water levels. However, the Board did note that ash pond seepage was likely to offset the effects of construction dewatering to i some extent.

(b) The basis of NIPSCO's assumptions concerning the

status of NIPSCO's fly ash ponds are contained i

in the following documents:

For 3 (a) (i) and (ii)

Agreement between the Department of Interior and Northern Indiana Public Service Company signed I by NIPSCO on February 24, 1978.

For 3 (a) (iii)

Report 78-138 " Effects of Seepage from Fly-Ash Settling Ponds and Construction Dewatering on Ground-Water Levels in the Cowles Unit, Indiana l

Dunes National Lakeshore, Indiana," dated January

1979 and prepared by the USGS (Pages 58 to 85).

For 3 (a) (iv)

Report 80-1105 " Reassessment of the Effects of Construction Dewatering on Ground-Water Levels in the Cowles Unit, Indiana Dunes National Lakeshore, Indiana" prepared by the USGS (pages 17 to 48).

For 3 (a) (v)

Initial Decision before the Atomic Safety and Licensing Board in the matter of North ( n Indiana Public Service Company (Bailly Generating Station Nuclear 1) (Page 75).

4. Please describe in detail each injection point for NIPSCO's proposed dewatering mitigation system.

ANSWER: A description of NIPSCO's proposed dewatering mitigation system for the unconfined aquifer is contained on Pages 12-14 of Sargent & Lundy Report "Hydrogeologic Evaluation of Construction Dewatering, Bailly Generating Station, Nuclear-1", March 30, 1978 and in a July 20, 1978 letter from Mr. R. J. Bohn of NIPSCO to Mr. Ronald L. Ballard of the NRC responding to NRC questions regarding the above report. Both of these documents have been provided to PCCI in response to its second document request.

The mitigation system for the confined aquifer has not yet been designed and, therefore, a description of the injection points is not available.

5. Please state the proposed flow rate or rates for the replacement water of NIPSCO's proposed dewatering mitigation plan.

ANSWER: Flow rates for the dewatering mitigation system will vary as required to prevent significant drawdown of ground-water levels beyond the NIPSCO/ National Park Service property line. These specific rates will be determined during system i

operation depending on need and cannot be specified now.

Pump Casir.g: -10' (xii) Tendon Tunnel Sump: -22' (xiii) Service Building Petipheral Sump: -10' (xiv) Radwaste Building Sumps: -7' (xv) Radwaste Building Sumps: -8' (c) The amount of water which will be removed for each of the above instances of dewatering is not known at this time.

(d) In all cases dewatering is intended to provide a dry excavation in which construction may proceed.

(e) In all cases dewatering will be seguired until work on that p9rticclar item has reached the point where the excavation has been backfilled to ap-proximately 2 feet above the groundwater level.

The rate of dewatering is unknown at this time.

(f) For purposes of answering this Interrogatory, -

IiPSCO assumes that each point shown on " Attachment I" to PCCI's Third Set ;f Interrogatories is as shown below:

Mineral Springs Road 10 (N 1,507,800 E 494,200)

In all instances cited above, the lacalized dewatering activity will have no effect on any of the points numbered 1 through 10 on " Attachment I" to these Interrogatories.

7. In " Northern Indiana Public Service Company's Response to the People of the State of Illinois' First Set of Interrogatories
to NIPSCO" filed July 8, 1981, in response to Interrogatory 8 (a) you state "[g]eneral consttuction dewatering is now being conducted and will be required for the period of time necessary to bring the facility foundationc to grade level. This is estimated to

{ be between 18 and ~ 0 mor.ths af ter construction resumes." Please i

state the bases for your estimation that it will take 18 to 30 months to bring the facility foundations to grade level.

_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ __=_= _-__ - _ - .-. . . . _

ANSWER: C. F. Braun's Cetailed Master Schedule, Revised 2/22/80, indicates that the foundation mats for the Reactor Building, Radwaste Building and Off-Gas Building will be completed approxi-mately 17 months after resumption of construction. Shortly after completion of these basemats it is expected that the depressuriza-tic, system for the confined aquifer could be rhut off, thus resulting in the 18-month estimate of the earliest time that a por tion of the dewatering system would be shutdown. The above schedule also indicates that backfill to grade v'11 be completed 28 months after resumption of construction, at which time it is expected that the ba!snce of the dewatering system could be shut off. Allowing a two month contingency for potential delays in the NRC's review of the piling installation prior to allowing concrete to be poured resulted in the 30 month estimate of the latest time by which dewatering should be completed.

8. Please provide all calculations upon which your responses to Interrogatories 13 (a) (1) through 13 (a) (4) of People of the State of Illinoin' First Set of Interrogatories to NIPSCO are based.

j ANSWER. For the unconfined 3quifer, NIPSCO's response was based on the proposed dewatering mitigation program preventing any significant off-site effects of dewatering the unconfined aquifer. Thus, no calculations were required. For the confined aquifer, NIPSCO relied on the calculations described in D'Appolonia I

to Porter County Chapter Intervenors' First Set of Interrogatorier, "

1 filed April 8, 1981, in response to Interro'atory 8, you attached i

a table described as " Table I - NIPSCO LOAD A.'D CAPABILITY DATE."[ sic]

In that table, you described " Purchase Power - MW" for the years 1980 through 1994. For each such year, please state:

(a) Whether the amounts shown in Table I u.e the

maximum amount of power that can be purchased under the terms of the purchase power agreements; (b) Whether you are obligated to purchase that amount, or whether your purchase is optional; (c) If a purchase is obligatory, the number of megawatts which you are obligated to piirchase.

ANSWER:

~

(a) Yes, except for the 100 MW value shown for the year 1988 which has not yet been secured by contract.

(b) NIPSCO is obligated to purchase power from three sources in the amcants shown below:

" Note 2" 10% of Marble Hill Unit 1 from date of commercial operation (Late 1986) through September 30, 1987.

" Note 3" -10% of Marble Hill Unit 1 from date of commercial operation (Late 1986) and 10% of Marble Hill Unit 2 from date of commercial operation (Late 1987).

(c) See response in 12(b).

13. In footnote (1) of " Table I" referred to in Interrogatory 12, you refer to a "156 MW derating of generating capacity in 1979." Please state the reason for such derating and identify the unit (s) derated.

ANSWER: Adjustments to the Northern Indiana Public Service Company generation capability were made to more accurately reflect the capability actually available to serve the system load under operating conditions. The Units which have been deratad are:

Michigan City Units 2 and 3, Mitchell Units 4, 5, 6 nnd 11 and Bailly Units 7 and 8.

14. PlrSse explain the reason for each action or situation described in footnote (7) of " Table I" referred to in Interrogatory 12.

ANSWER:

l (a) Includes 113 MW from WVPA of MH 2:

Marble Hill Unit #2 is scheduled for commercial

operation in late 1987. By contractual arrangement

with WVPA, NIPSCO will be receiving as purchase and imported power 113 MW of the WVPA portion of Marble Hill #2.

(b) Termination of PSI power from MH1 on 9/30/87:

Marble Hill Unit #1 is scheduled for comn.ercial operation in late 1986. Py contractual arrangement with 73I, NIPSCO will be purchasing 113 MW of the PSI portion of Marble Hill #1 from its commercial date of operation until 9/30/87.

(c) End of Firm purchase:

Effective January 1, 1978, NIPSCO is purchasing 400 MW of Firm power from I&M. This contract s

expires recember 31, 1987.

(d) 100 MW purchase power during 1988:

4 This 100 MW in 1988 is required to maintain our minimum reserve margin but has not been secured by contract.

15. Does NIPSCO have any plans, stand-by, tentative or

, otherwise; to reduce future peak electrical demand? If your answer is yes, please describe such plans in detail.

l ANSWER: Yes, NIPSCO does have plans which should aid in the reduction of peaks. The rate design of 2 rate schedules l (832 and 833) applicable to the larger customer contain provisions i

which provide an economic incentive for them to reduce their demands on the NIPSCO system. This economic incentive has been in effect for a number of years and has proven very successful in reducing the demand at times of system peak.

In addition, NIPSCO has, as part of its electric service tariff, an interruptible rate schedule which allows the Company to request i a reduction of customer demand upon 10 minutes notification.

Thi: schedule provides for 400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> of reduction to be available at the Company's request in a 12-month period.

NCPSCO also has a rate schedule which makes provisions for customere i

to install peak shaving generation equipment to allow them to

'I limit their demands on the NIPSCO system.

, 18. (a) Using all of the following assumptions, please i

state what you contend would be the water table level or surface water level at each of the points l numbered "1" through "10" with circles around

! the numbers on " Attachment I" to these interrogatoriet:

)

i --

uewatering for 30 months at a rate sufficient to reach the lowest point necessary for con-struction of the Bailly plant;

-- With the effects of the slurry wall as presently installed;

-- In the absence of any mitigation program; and With no seepage from NIPSCO's ash ponds and no dewatering for the sealing of NIPSCO's ash ponds.

(b) Please state all other assumptions used in calculating your responses to subsection (a), including but not limited to the rate of dewatering assumed, and whether your assumptions include a hydraulic connection between " Unit 1" and " Unit 3" .

(c) Please give all calculations used in formulating your answers.

(d) Please state the bases for youi answers.

For the purpose of answering these Interrogatories, NIPSCO may assume that " Unit 1" and " Unit 3" refer to those units so described in "SGS reports78-138 and 80-1105.

ANSWER:

(a) NIPSCO rrsumes that the points numbered "1" through "10" on " Attachment I" to these Interrogatories are as defined in the response to Interrogatory 6(f) above. Since none of these points is located within.the limits of an interdunal pond, no surface water levels have been calculated.

NIPSCO has not attempted to identify the water table levels of any of these ten points. However, drawdowns (decreases from the seasonal groundwater levels) have been estimated for the unconfined aquifer dewatering system and for the confined aquifer depressurization system. NIPSCO has determined that the total drawdown resulting from the unconfined aquifer dewatering system and the confined aquifer depressurization system will be less than the drawdown which was approved by the Atomic Safety and Licensing Board at the time of the Construction Permit hearing. Thus no calculations have been performed to identify specific drawdowns at points 1 through 10.

(b) Not applicable.

(c) Not applicable.

(d) The presence of a slurry wall and pumping at a lower rate than that discussed in the construction permit hearing will result in less drawdown than that approved by the Licensing Board following the Construction Permit hearings.

19. (a) Using all of the following assumptions, please state what you contend would be the water table or surface water level at each of the points numbered "1" through "10" with circles around the numbers,
on "Attaahment 1" to these interrogatories

Dewatering for 30 months at a rate sufficient to reach the lowest point necessary for con-struction of the Bailly plant; With the effects of the slurry wall as presently installed; With NIPSCO's proposed mitigation program; and With no seepage from NIPSCO's ash ponds and no dewatering for the sealing of NIPSCO's ash ponds.

(b) Please state all other assumptions uo a in calculating your responses to subsection (a), including but not limited to the rate of dewatering assumed, and whether your assumptions include a hydraulic connection between " Unit 1" and " Unit 3."

ANSWER:

(a) The mitigation program will be designed to maintain the groundwater levels at the NIPSCO/ Indiana Dunes National Lakeshore property line within one foot of seasonal levels. The groundwater levels at both points 1 and 2 which are located on NIPSCO property will be controllable with the mitigation system. There will be no change in groundwater levels at points 3 through 10, inclusive.

(b) The mitigation program design has not been completed.

However, the recharge systems will be properly sized and located to allow mitigation of any drawdown at the property line.

(c) No calculations were required to prepare the answers to Interrogatories 19(a) and (b) above.

(d) The bases for the answer is provided in Interrogatory 19(b) above.

20. (a) Using all of the following assumptions, please state what you contend would be the water table level or surface water level at each of the points marked "1" through "10" with circles around the numbers on "Tttachment I" to these interrogatories:

Dewatering for 30 months at a rate sufficient to reach the lowest point necessary for construction of the Bailly plant; s--,

c In the absence of the slurry wall; In the absence of any mitigation program; and With no seepage from NIPSCO's ash ponds and no dewatering for the sealing of NIPSCO's ash conds.

(b) Please state all other assumptions used in calculating your responses to subsection (a), including but not limited to the rate of dewatering assumed and whether your assumptions include a hydraulic l connection between " Unit 1" and " Unit 3."

(c) Please give all calculations used in formulating your answers.

(d) Please state the bases for your answers.

ANSWER:

(a) The assumptions specified in this hypothetical question describe the conditions relied upon by NIPSCO and its consultants in the Bailly Nuclear-1 Construction Permit Hearing in 1973 before the slurry wall was considered or installed. The drawdown would be that which was reviewed by the Licensing Board in its initial 6ecision, 7 AEC 557 (April 5, 1974). No specific drawdowns were calculated for points 1 through 10.

l (b) Those described in the testimony of the Construction Permit Hearing, to which PCCI was a party.

(c) Those described in the testimony .f the Construction Permit Hearing, to which PCCI was a party.

(d) See (b) and (c) above.

37. In " Northern Indiana Public Service Company's Response to Porter County Chapter Intervenors' First Set of Interrogatories, in response to Interrogatory 7, you stated "NIPSCO believes that a minimum reserve margin of 20% excluding combustion turbines

[ footnote omitted] is the minimum reserve margin required to maintain minimum system reliability." Please state the cases for chis statement.

ANSWER: NIPSCO experience has proven that when our reserve margin, excluding combustion turbine units, falls below 20% we have insufficient restrves to perform periodic scheduled maintenance and other repairs while still maintaining adequate system capacity to protect against forced or unforeseen outages on the remaining generating units. NIPSCO's electric system load factor, which is consistently one of the highest in the industry, results in less off-peak capacity to be used for maintenance and forced outages than systems with lower load factors.

38. What was NIPSCO's estimate of the minimum reserve margin required to maintain minimum system reliability at the time it made application for a construction permit for Bailly N-l?

ANSWER: Fifteen percent.

39. What was NIPSCO's estimate of the minimum reserve margin required to maintain minimum system reliability at the time of the issuance of the construction permit for Bailly N-l?

ANSWER: Fifteen percent.

AN3WER: From March 1972 when NIPSCO first began monitoring of pond levels, through September 1973, NIPSCO's records of inter-dunal pond and ash por.3 levels consist of handwritten tabulations of water levels taken from measuring stakes located in the respective ponds. Beginning in October 1973 and continuing through April 1974, NIPSCO utilized standard survey instruments and techniques to measure pond levels, and recorded the necessary information, including pond levels, on special data sheets developed for the  ;

monitoring program.

From October 1973 when the first monitoring well was installed, through April 1974, groundwater levels were recorded on weekly charts t; automatic level recorders on the individual wells.
