LILCO'S RESPONSES AND OBJECTIONS TO SUFFOLK COUNTY'S THIRD SET OF INTERROGATORIES AND REQUESTS FOR PRODUCTION OF DOCUMENTS REGARDING EMERGENCY BROADCAST SYSTEM LILCO hereby responds to Suffolk County's Third Set of Interrogatories and Requests for Production of Documents on the EBS issues, dated March 11,1988.II I. General Answers and Objections LILCO gives the same general answers and makes the same general objections to the County's third set of interrogatories and requests for production that it made in its March 7, 1988 Responses to the County's first set of interrogatories.
II. Answers and Objections to Interrogatorios
~
Suffolk County Interrogatory No.1 The Cohen and Dippell Engineering Report concerning the field strength measurement survey of radio stations WEZN (FM) and WPLR (FM), dated June 1987 (hereaf ter "June 1987 Engineering Report") indicates (at page 2) that a rectangular grid of approximately 3 kilome-ters was used in connection with the field strength measurement tests conducted by Cohen and Dippell. (a) Why was a grid of approximately 3 kilometers used? (b) Was any consideration given to using a different size grid? (c)If so, specify precisely what consideration (s). (d)If no consideration was given to using a different size grid, explain why this was the case.
Response: The June 1987 engineering report explains why an approximate 3 kilometer rectan-gular grid was used. As that report states, 8803310o41 PDR ADOCK O sehb22 PDR G
1/ The County served its Third Set of Interrogatories by telecopier at about 7:00 p.m. on Friday, March 11. LILCO considers the interrogatories served on Saturday, March 12.

A rectangular grid of approximately 3 kilometers was selected to en-compass the boundaries of the EPZ and to meet the minimum num-ber of measurement locations according to the formula 0.1 (P) i pro-vided in the FCC Rules. This procedure is outilned in Section 73.314 (c)(1)(ii) of the FCC Rules and is based on the population within the area or community being surveyed.
Further, as stated in the May 12, 1987 letter from Robert W. Guill to Douglas M. Crocker, which was produced to the County on March 1,1988, the EPZ was assumed to be one whole community for purposes of the FM measurement survey. In short, the field measurement sur-veys were conducted according to 47 C.F.R. S 73.314 of the FCC rules. No consideration was given to not following these niles.
Suffolk County Interrogatory No. 2 The June 1987 Engineering Report (at page 2) notes that 1980 U.S. census data were used to determine the minimum number of measurement locations. (a) Why were 1980 U.S.
census data used? (b) Why was a 1988 census projection not used? (c) Was consideration given to using any other census data, including projected population data? (d) If so, what data? If not, why not?
Response: Cohen and Dippell used 1980 census data in accordance with S 73.314 (c)(1) of the FCC regulations. The 1980 census is an "appropriate source" of population information be-cause it constitutes the most recent established population figures. Projected population data was not used because, by definition, it is more speculative than the established 1980 data. The answer to (c) is no.
l Suffolk County Interrogatory No. 3 l
The June 1987 Engineering Report (at page 3) states that, based upon a listening test conducted by Cohen and Dippell, WPLR (FM) provides "a very good signal level throughout the measured area." What qualitative and quantitative criteria were used in determining that WPLR (FM) provides "a very good signal level?"
Response: The criteria used were that there be a consistent, clear, listenable signal without interruption.
Suffolk County Interrogatory No. 4 The June 1987 Engineering Report (at page 3) notes that during the listening test, "nothing was heard that suggested any reception problems." What level or amount of interfer-ence would have constituted a "reception problem" for purposes of the Cohen and Dippell re-port?
l l
g Response: Interruption, loss, or switching of the broadcast signal to other stations would have constituted a reception problem.
Suffolk County Interrogatory No. 5 The June 1987 Engineering Report (at page 3) notes that field strength measurements were made with a receive antenna elevated 30 feet above ground level. (a) Why was the re-ceive antenna elevated to a 30 foot elevation? (b) Was any consideration given to taking any meaeurements with the receive antenna elevated to a different height? (c) If so, specify pre-cisely what consideration (s). (d) Would there have been any variation in the measurements if the receive antenna had been elevated 6 feet above ground level? (e) If so, what would that variation have been?
Response: The receive antenna was elevated to 30 feet to comply with FCC regulations, which require an antenna elevation of nine meters (29.5 feet). See e S ?3.314 (b)(2). The answer to (b) is no. There might have been variation in the measurements if the receive antenna were elevated to a height of six feet, but that is irrelevant because the regulations call for the antenna to be elevated to nine meters, not six feet.
Suffolk County Interrogatory No. 6 The June 1987 Engineering Report (at page 3) notes that field strength measurements were taken with a "horizontally polarized dipole receive antenna." (a) Why was such an anten-na used? (b) Was any consideration given to using a vertically polarized antenna? (c) If so, specify precisely what consideration (s)?
Response: A horizontally polarized dipole receive antenna was used because that is the type specified in FCC regulations. The answer to (b) is yes. In fact, measurements using a verti-cally polarized receive antenna were made simultaneously with the horizontal measurements.
Both sets of measurements are contained in the field notes that were produced to the County on March 11,1988. The June 1987 Engineering Report reflects only the horizontal measure-ments because they are the ones recognized by the FCC.
Suffolk County Interrogatory No. 7 What is the ratio of horizontal to vertical polarization from: (a) WPLR (FM); (b) WRCN (FM); and (c) WLNG (FM)?
j Response: The ratio for each is 1.
i
Suffolk County Interrogatory No. 8 Assuming that the instrumentation used to take the field strength measurements that wem reported in the June 1987 Engineering Report was properly calibrated, what is the mar-gin of error - both in percentage and mV/m - of the field strength measurements made on radio station WPLR? Please provide a copy of the calibration report and any other documents relating to the June 4,1986 calibration of the field strength meter referenced at page 3-4 of the June 1987 Engineering Report.
Raiponse; The manufacturer's calibration report is provided with these responses. The de-sired answers can be derived from that report.
Suffolk County Interrogatory No. 9 For every reading provided in the June 1987 Engineering Report, what is the uncertain-ty due to instrument, antenna and/or other inaccuracles?
Response: See LILCO's Response to Interrogatory no. 8.
Suffolk County Interrogatory No.10 Were there any deviations from the FCC regulations contained in Title 47 of the Code of Federal Regulations with respect to the procedures used in the June 1987 Engineering Re-port? If so, please specify each and every such deviation.
Respouse: No.
Suffolk County Interrogatory No.11 (a) With respect to Table VI of the June 1987 Engineering Report, why is the range of readings in the column entitled "Min / Max" 29.4 dBu for Point !? (b) Identify every f actor, rea-son or basis for such a range. (c)Is this range possible elsewhere within the area measured by Cohen and Dippell?
Response: The range of 29.4 for Point 1 is arrived at by subtracting the minimum measured horizontal field strength from the maximum. Ranges of measured field strength are possible at all measuring points. The ranges measured in the field strength measurement survey re-ported in the June 1987 engineering report are identified in Table VI of that report.
Suffolk County Interrogatory No.12 With respect to Table VII of the June 1987 Engineering Report, how was the elevation of each point determined?
Response: The elevation of all measuring points was taken from United States Geological Sur-vey (U.S.G.S.) topographic quadrangle maps (7.5 minute series).
5 Suffolk County Interrogatory No.13 (a) Can field strength measurements cr an FM signal vary depending upon when such measurements are made? (b) Can such measurements vary during the day and night? (c) Can such measurements vary during the different seasons of the year?
Resporse: The answer to (a) is yes, although such variation is not significant. The answer to (b) is no. The answer to (c) is that it is possible for measurements to vary during dif ferent sea-sons, for example, because of tree foliage.
Suffolk County Interrogatory No.14 (a) Can field strength measurements of an AM signal vary depending upon when such measurements are made? (b) Can such measurements vary during the day and night? (c) Can such measurements vary during the different seasons of the year?
Response: The answer to (a), (b), and (c) is yes.
Suffolk County Interrogatory No.15 The Cohen and Dippell Engineering Report concerning the computed signal contours for radio stations WICC, WELI, WGLI, WRHD, WLIM, WLNG AM and FM, WPLR and WRCN, dated September,1987 (hereaf ter "September 1987 Engineering Report") references "interference-free contours." (a) Identify how the interference-free contour for daytime reception of each FM station in LILCO's EBS network would vary from the interference-free contour for night-time reception. (b) Identify how the interference-free contour for daytime reception of each AM station in LILCO's EBS network would vary from the interference-free contour for night-time reception. Please provide a copy of any and all documents referencing such variances.
Response: The answer to (a) is that the interference-free contours for daytime operation of each FM station do not vary from the nighttime interference-free contours for such stations.
The differences between the daytime and nighttime interference-free contours for the AM stations are as shown in the September 1987 engineering report. All relevant documents have
, been provided.
I Suffolk County Interrogatory No.16 Identify any changes or modifications made to the FCC data used to compute the interference-free contours included in the September 1987 Engineering Report. Please pro-vide a copy of any and all documents referencing in any way such changes or modifications.
Response: No changes or modifications to FCC data were made.
Suffolk County Interrogatory No.17 l
l Identify all FM stations that cover any part of the EPZ at nighttime, and designate the specific parts of the EPZ that are covered. Identify all AM stations that cover any part of the EPZ at nighttime, and designate the specific parts of the EPZ that are covered. Please provide a copy of any documents relating to such FM and/or AM coverage.
4 Reponse: LILCO objects to Interrogatory no.17 to the extent that it is redundant of Inter-rogatory no.17 in the County's first set of interrogatories, which asked LILCO to describe por-tions of the EPZ that are not covered by AM or FM signals. LILCO also objects to Interrogato-ry no.17 because it is not limited to stations in the Shoreham EBS; it instead asks for the identity of all AM and FM stations that cover parts of the EPZ at night. Information about stations not in the Shoreham EBS is not relevant. In any case, the intormation sought is contained in public FCC files, and thus is as accessible to the County as it is to LILCO.
To the extent Interrogatory no.17 seeks information about the ni,t . time coverage of AM and FM stations in the Shoreham EBS, that information is contained in the Cohen and Dippell studies that have already been provided.
Suffolk County Interrogatory No.18 Please provide a copy of any maps of the EPZ that show only the interference-free contours of AM stations in LILCO's EBS network.
Response: The only responsive map is the one contained in the June 1987 engineering report on WINS and WELI, which was provided to the County on March 1,1988. The contours of the other AM stations in the Shoreham EBS are shown in the September 1987 report.
Suffolk County Interrogatory No.19 (a) Did any person, including but not limited to Cohen and Dippell, recalculate the sig-nal contours depicted in the September 1987 Engineering Report that, according to the Affi-davit of Ralph E. Dippell, Jr., (Attachment 9 to LILCO's Nov. 6 Summary Disposition Motion),
were generated from FCC-recognized signal strengths in the radio stations' license files? (b)
If so, please specifically identify what recalculations were made. (c) Please provide a copy of any documents referencing such recalculations.
Response: All contours depicted in the September 1987 Engineering Report were taken from FCC files with the exception of the contours for WPLR-FM and the nighttime interference-free contour for WELI (AM). Those contours were generated from measured field data that was previously collected and submitted. Thus, with the stated exceptions FCC data was relied upon.
, Suifolk County Interrogatory No. 20 (a) How far beyond the signal contours depicted in the September 1987 Engineering Re-port does LILCO expect the AM radio stations in the EBS network to be heard? (b) How far beyond the signal contours depicted in the September 1987 Engineering Report does LILCO ex-pect the FM stations in the EBS network to be heard? (c) Please specify the basis for LILCO's opinion regarding this interrogatory.
Response: Experience shows that broadcast signals do not stop at the contour lines. An exact determination of the extent or reach of the signals cannot be made, however, without con-ducting tests.
Suffolk County Interrogatory No. 21 Identify any studies, analyses and/or tests that have been performed or conducted with respect to whether the tone alert receivers provided the radio stations in LILCO's EBS net-work can, in f act, be activated by WPLR's signal. Please provide a copy of any and all docu-ments concerning such studies, analyses and/or tests.
Response: No such "studies" or "analyses" have been performed. The tone alert receivers were checked to make sure they were functional at the time they were delivered to LILCO. The only other "tests" that have been conducted are those mentioned in LILCO's Responses to In-l terrogatory no.19 in the County's first set of interrogatories. All documents regarding those tests were provided with LILCO's Responses to the County's first set of interrogatories.
! Suffolk County Interrogatory No. 22 Identify any studies, analyses and/or tests that have been performed or conducted with respect to whether the tone alert radios provided by LILCO to schools, hospitals, rpelal f acil-ities, large employers, and others can, in f act, be activated by WPLR's signal. Please provide a copy of any and all documents concerning such studies, analyses and/or tests.
Response: As discussed by Mr. Crocker in his March 8 deposition (at 57-59), WPLR conducts weekly EBS tests. Upon delivery and installation of the tone alert radios at special facilities, schools, etc., LILCO asks those facilities to contact LILCO if they notice that their tone alert radios are not activated once a week by WPLR's signal. LILCO has received no phone calls from these organizations saying that the radios have not been activated by WPLR's signal. No other tests, studies, or analyses have been performed. There is no documentation concerning tests of the tone alert radios at these facilities.
1 t - __-_
1 Suffolk County Interrogatory No. 23 What is the minimum signal strength necessary to trigger and/or activate the tone alert receivers provided the radio stations in LILCO's EBS network?
Response; This Interrogatory is redundant of Interrogatory no. 7 in the County's second set of interrogatories. See LILCO's Response to Interrogatory no. 7.
Suffolk County Interrogatory No. 24 (a) Identify any studies, tests and/or analyses of LILCO's EBS network that were con-templated. (b) Identify any studies, tests and/or analyses of LILCO's EBS network that were started or initiated, but not completed or finalized.
Response: LILCO objects to Interrogatory no. 24 on the ground that it seeks information that is not relevant to the issues in this proceeding and is not reasonably calculated to lead to the discovery of admissible evidence. LILCO already has identified and provided copies of all doc-uments concerning all studies, tests, and analyses conducted to date that LILCO will rely on to show the coverage of the radio stations in the Shoreham EBS. Any tests, analyses, etc. that may have been contemplated by LILCO at some point in time but were not in fact undertaken are not relevant.
Without waiving this objection, LILCO states that, as mentioned by Mr. Crocker in his March 8 deposition, LILCO personnel and counsel have discussed the possibility of conducting field tests on the AM stations in the EBS. As Mr. Crocker testified, however, no formal deci-sion to perform such tests has been made. Answering further, LILCO states that no studies, tests, etc. were started but not completed or finalized.
Suffolk County Interrogatory No. 25 l
(a) With respect to Figures 1 and 2 of the September 1987 Engineering Report, what, if any, assumptions were made concerning the ground conductivity of Long Island? (b) What, if any, assumptions were made concerning the coriductivity of Long Island Sound?
Response: The only conductivity assumptions that were made are those based on FCC esti-mated conductivities provided in FCC regulations.
Suffolk County Interrogatory No. 26 Identify the back-up or alternative power source for each of the radio stations included in LILCO's EBS network. Please provide a copy of all documents referencing or mentioning in any way such back-up or alternative power sources.
4 Response: LILCO objects to Interrogatory no. 26 on the ground that it seeks information that is irrelevant to the admitted contentions in this proceeding and is not reasonably calculated to lead to the discovery of admissible evidence on the admitted contentions. The admitted con-tentions do not raise the issue of the adequacy of backup equipment at the EBS radio stations.
The contentions admitted for hearing raise only the issues of the strength of WPLR's broadcast signal within the EPZ, the alleged attenuation of that signal due to geography and directional orientation of receiving antennae in the EPZ, the lack of AM broadcasting by WPLR, and al-leged gaps in the EBS' nighttime AM coverage. The admitted contentions do not f airly raise -
or even mention - the issue of backup power sources.
Moreover, LILCO objects to Interrogatory no. 25 to the extent that it questions the backup power sources for the seven EBS members stations that were previously in the WALK-triggered EBS that was litigated and approved by the Boaid. The County could have raised that issue in the WALK hearings on Contention 20 but did not. Thus, the adequacy of backup power supplies for the secondary stations on Long Island is not among the "carlicr-admitted is-sues" reopened by the Commission, and the County cannot raise that issue for the first time now. The matter is res ludicata.
! Without waiving these objections, LILCO notes that the backup power source for WPLR l
[ is listed on Attachment 4 to LILCO's November 6 Summary Disposition Motion and is described in the Motion itself (at pp. 8-9).
Suffolk County Interrogatory No. 27 Do all radio stations in LILCO's EBS network have a person capable of operating the station on the premises of the station at all times? Identify any stations that do not, and for each such station identify the times when there is not a person on the premises capable of op-erating the station.
Response: LILCO objects to Interrogatory no. 27 on the ground that it seeks information that is not relevant to the admitted contentions and is not reasonably calculated to lead to the dis-covery of admissible evidence on the admitted contentions. The contentions specifically raise only the issue of coverage within the 10-mile EPZ: they say nothing about the existence or
i qualifications of radio station personnel. Moreover, LILCO objects to Interrogatory no. 27 to the extent that it seeks information concerning the seven EBS stations that were previously in the WALK-triggered EBS that was litigated and approved by the Board. The County could have raised the issue of the existence of qualified station operators at these stations earlier in this proceeding but did not. The County cannot raise that issue for the first time now.
Without walving these objections, LILCO answers that WPLR, WICC, and WELI each have a person capable of operating the station on the premises at all times.

Model ANT-71, Serial No.100 Submitted by Potomac Instruments, Inc.
Silver Spring, Maryland 20910 .
The data in this report are for use in =aking F.v.S cv =easure=ents only -
and are not valid for broadband interference =easurements. ,
The dipole antenna was connected to a detector having a VSWR of less than 1.05 through a 12.19 =eter (ho foot) length of RG 223 U cable supplied with '
the antenna. The voltage was =easured at the output of the cable. The out- .
put voltage of the antenna may be expressed in ter=s of the voltage =easured at the cable output by including the loss factor of the cable. Since the -
cable was not calibrated at NES, the accuracy of this part of the calculation cannot be certified.
The antenna was calibrated at a height of 914 meters (30 feet) in a hor- -
izontally polarized field at all frequencies. In addition, a calibration was ,
made for two different dipole element lengths for some frequencies. The antenna was also tested in a horizontally polarized field at 2.13 =eters -
(7 feet) at selected frequencies.
Prior to calibration, the orientation of the antenna (with respect to the trans-mitter directien) which produced =axi=um output from the test antenna was de-termined. This orientation was such that the direction of propagatien of the
- incccing wave is defined by a line drawn from *the center of the 1/k-20 counting hole to the BNC rf output connector.
Tests were also performed to determine the sensitivity of the test antenna to vertically polarized fields.
Field strength =ay be determined with this dipole antenna by =easuring the
- output voltage of the antenna when ter=1nated in a 50 ohm load and applying .
the following equation:
E = KV Where: ,
E = unknown field strength in volts /=eter. '
K =
antenna factor in (volts /=eter)/ volt.
V = output voltage of antenna (terminated in 50 ch=s) in volts. .

(Also see the RO.71 described under Optional Accessories.)
The FIM 71 operates from a battery of ten (10)"D" size cells. Standard carbon zine cells are suitable for many applications: alkaline eells provide greater life with heavy duty and/ or extreme tempera-tures. The POWER switch has a momentary TEST position which allows the power source to be checked l4 on a special panel meter scale.
A rechargeable battery kit is also available: the battery and charger fit into the instrument battery compartment. An AC operated power source is also available for continuous"bench" operation. (See l E
t Optional Accessories.)
1.1.2 Antenna g The ANT 71 antenna consists of a pair of telescoping elements attached to a rugged light weight a housing which encloses a wide band balun. The b.rtun is designed to efficiently couple the antenna to a 50 ohm unbalanced system over the specified frequency range. The balun output is provided at a BSC g connector on the bottom of the balun housing. l The antenna elements are adjusted for an effective half wavelength (overall)in accordance with a eurve, supplied, which relates element length to measured frequency, g '
The balun housing includes a standard % -20 "camera-type" bushing which facilitates mounting. E For near ground measurements, the antenna is normally attached to the selective voltmeter on a short tele-scoping mast. With the aid of a leather neck strap, supplied, the instrument can be conveniently hand held, g or a unipod can be used. (See Optional Accessories.) When not in use, the antenna and mast are easily col- {
lapsed into a storage pesition on the side of the mstrument.
For precise elevated measurements, the antenna can be mounted to any mast with a % -20 threaded g stud such as provided on camera tripods. An elevation of 30 feet has been standardized for the FCC approved [
"TASO" tests. Antenna cables are supplied - see Accessories.
The FIM 71 antenna was calibrated by the National Bureau of Standards in an extensive series of g-tests performed at Boulder, Colorado. (See Section 5.) A curve is supplied which relates the ratio of antenna l, output voltage to field strength, at the measured frequency. Because of the method of calibration, these "antenna factors" are independent of cable length and the voltmeter used; as long as the antenna is terminated in a 50 ohm system. Antenna Factor curves are supplied for elevations of both 7 feet and 30 feei over the specified frequency range.
[
The fact that the antenna and the receiver interface at 50 ohms allows the use of many commercially available RF devices such as attenuators, power dividers, filters, etc. (;
The FIM 71 is furnished with a removable cover which protects the front panel, and also provides stoisge for the antenna cables, antenna scale, and neck strap. With the cover in place, and the antenna and mast in the storage position, the user obtains a rugged and truly portable package. l Table 1 1.
