March 20, 1987 ATTORNEY GENERAL JAMES M. SHANNON'S REPLY TO APPLICANTS' ANSWER TO ATTORNEY GENERAL'S MOTION TO RECONSIDER Attorney General James M. Shannon hereby files this limited reply to Applicants' Answer to Motion of Attorney General James M. Shannon to Reconsider Late-Filed Contention with Revised Basis and to Reopen the Record, dated March 13, 1987 The Attorney General files this reply to apprise the Board of two apparent misrepresentations in Applicants' pleading.

The two misrepresentations and the Attorney General's response thereto are as follows:

1.

Applicants state at page 3 of their pleading, that

" utilization of the appropriate 1/3 octave band is the correct procedure."

Repeating this conclusion, the Callendrello

r

..k Affidavit submitted in support of Applicants' Answer states that' FEMA guidance specifies that " background noise level should be measured in th(e) one-third octave band.

Calendrello Affidavit at p.

2, citing Standard Guide for the Evaluation of Alert and Notification for Nuclear Power Plants, FEMA-43, dated September, 1983.

Applicants' pleadings thus imply that measurements taken in the full octave band are inappropriate and not in accord with the FEMA guidance.

In fact, FEMA made clear when publishing the more recent guidance, Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants, FEMA-REP-10, dated November, 1985, that background sound measurements can be taken in either the one-third or the full octave band.

See 50 Fed. Reg. 43084, 43085 [" Attachment A" hereto].

It is clear, then, that background sound measurements taken by both the Attorney General and the Applicants were performed in appropriate octave band widths and that a material dispute a

to fact exists concerning whether the siren system in Merrimac indeed " exceeds the average measured summer daytime ambient sound pressure levels by 10 dB" as required by FEMA.

See FEMA-REP-10, at E-8, E-9.

In fact, HMM Associates, upon whom Applicants rely for their current measurements, stated in the Seabrook Station Public Alert and Notification System Final Design Report, dated January 1984, [ Final Design Report], that sound levels observed at each of the Seabrook sites " typically s_

k span a range of 30 dB or more."

Final Design Report at p.

12

[" Attachment B" hereto).

It is not surprising, therefore, that the measurements submitted by the Attorney General and the Applicants vary somewhat.

Taken as they were on different times for short periods of time, they serve to prove only that winter background noise varies a great deal, probably due to the variation in background noise generated by traffic and wind bluster.

This raises the question of how one goes about measuring the " average summer daytime" background noise, as FEMA-REP-10 requires.

Logic and common sense suggest that such an " average" can be computed only from a series of measurements over a number of days with differing wind, weather, and traffic conditions.

Furthermore, it would be more appropriate to take these measurements using the LSO level, not the L90 level.

This, in fact, is what Applicants' experts at HMM recommended in the Final Design Report they conducted (see " Attachment B " ).-

In this report HMM stated that in determining the

" average daytime level," as required by FEMA, sound measurements should be provided in the L50 level, that is the sound level that is exceeded 50% of the time, rather than in the L90 level (the level used by Applicants to indicate compliance with the FEMA standard), which only indicates the sound level exceeded 90% of the time.

It is clear from all this that a reopening of the record is therefore warranted to determine whether sirens in Merrimac do meet the FEMA standard 3-

w

-' : w '

(

and, thus, whether there exists reasonable assurance that the notification sirens'in Merrimac~will be heard by that entire populace.

2.

Applicants state at page 5 of their Answer, as if it were relevant, that, "At a time when the siren system had yet to'be designed and constructed, Massachusetts showed no interest at all in raising a contention about the sirens of any kind."

In fact Massachusetts twice filed contentions related to 'he lack of a siren system prior to the design and t

construction of such system.

See Commonwealth of Massachusetts i

Supplement to Petition to Intervene, dated April 20, 1982, Contention 4; Contentions of Attorney General Francis X. Bellotti-Relative to Emergency Planning for thg State of New Hampshire, dated June 23, 1983, contention III.

When the siren system was later designed, it called for six sirens to be located in Merrimac, see Final Design Report, dated January, 1984, at p.

18.

Those six sirens were then reduced to three, see, e.g.,

State of New Hampshire RERP Rev.

1, Vol. 1, p.

2.1-11, dated June 1986, and it is only now that Applicants have indicated that they intend to install only two of those three sirens.

It is only now, therefore, that the Attorney General has cause to once again raise this issue of siren coverage.

The Attorney General strongly resents Applicants' attempts to call into question the motives of the Attorney General in raising this motion; such name-calling as e

g'.

o L

Applicants stoop to at page 5 of their Answer should have no place in this litigation.

If Applicants had last summer determined average background noise levels for Merrimac in accordance with the FEMA guidance, of which they were well aware, there would, perhaps, never have been a need for the Attorney General to file these motions to ensure adequate siren-coverage.

___m The background noise that contrioutes to the masking of a siren sound is contained in a relatively narrow frequency cand centered on the frequency of the predominant siren tone This cand, sometimes called the " critical cand," is very narrow:

typically 1/6 to 1/10 of an octave wide.

Filters for measuring the Dackground noise in such a narrow cand are not readily availaole.

The sirens to be installed around Seaurook Station will produce tones at 700 Hz.

Hence, the measurements reported nere were made with an octave-band filter centered at 500 Hz (i.e., a filter spanning the range f rom 353 Hz to 707 Hz).

Because tne octave cand contains much more noise energy than the critical cand of interest, the measured data were converted to equivalent 1/3 octave band levels by subtracting 5 dB (i.e., 10 log (1/3)).

FEMA suggests the use of 1/3 octave cands for ambient noise measurements.b Of course, tne critical cand is even narrower tnan 1/3 octave, so the data reported herein are somewhat nigher tnan the actual bacxground noise of interest, and nence more conservative.

2.4.6 Results E

The data sheets from each of the seventeen measurement locations are given in Appendix A.

Tne data are in tne form of "L-levels."

The L is the level that was exceeded 10% of 10 the time during the 1/2-hour sampling period; tne L50 was l

exceeded 50% of the time; tne L 90% of tne time; etc.

Tne 90, maximum and minimum momentary levels that were observed are ll also reported, along with tne equivalent level:

L The eq.

L is the level of a hypotnetical steady sound that would eq g

have had the same energy over the half-hour period as the actual, fluctuating noise.

Because sound is measured on a logarithmic scale, the L tends to be influenced by orief, 1

eq intense noises.

The data in Appendix A include the -5 d8 correction to 1/3-octave-band levels.

,The levels observed at each <fte tvnfen11v snan a ranga or 30 dB or more.

This raises the ouestion as to which level in that range should be used as the maskino level.

An estimate that is often used is the L level.

This is called the 90

" residual" level, and it generally characterizes the background in the absence of brief vehicles.b0 transient noise sources like passing For the purposes of this study a more conservative value, the L50, is used.

Tne L

's are tabulated on Table 2.3.

50 The L or median level, could be considered sn, reorasantativa of the " average daytime level" used by FEMA in FEMA-REP-1 and FEMA-43.

Fer sirens operating 15 minutes or longer, the L 50 would establish the nighest possible masking level.

For sirens operating less than 15 minutes, there would be some chance of masking at higher levels.

This enance would increase ~as the siren duration decreased.

Examination of the L levels on 50 Table 2.3 indicates that only one exceeds the 50 d8 " rural" design level provided by FEMA /NRC.

This is 53 dB at site #10 in downtown Portsmoutn.

The site is clearly in an urban area where FEMA /NRC's 60 d8 design background level applies.

Three otner sites are worth mentioning.

At site 3 in Salisbury, 50 d8 was observed and at Site 8 in Seabrook 48 dB was observed.

Both sites are close to Interstate 95 and receive relatively steady traffic noise from that source.

The siren system for these locations is designed for 60 dB (i.e.,

urban) background noise.

Finally, at site 16 in downtown Exeter, 48 dB was observed.

Siren coverage in that area is also designed for a 60 dB background.

At all other sites, the L

was 45 dB or less.

50 In conclusion, tne background noise measurements confirm that the FEMA /NRC design levels are suitable, and quite conservative.
