1.0 INTRODUCTION
I- The Atomic Safety Licensing Board ( ASLB) ruling LBP-83-11, dated March 8, 1983, as well as the recommendations of the NRC staff contained in the Environmental statement related to the operation
] I of Limerich Generating Station require that Philadelphia Electric Company (PECO) perform post operational noise curveys to ensure that "off-site noise levels in the vicinity of the Bradchaw I Reservoir Pumping racility during operation are not expected to be high enough above ambient levels to annoy nearby residents",
i PECO contracted United Engineers and Constructors, Inc. (UE&C) to perform both a baseline noise survey as well as the required ASLB post-operational noise survey at the Bradshaw Reservoir Facility.
This report satisfies the requirements for a post-operational I su rvey .
2.0 DASELINE AMBIENT NOISE SURVEYS The sounds normally present in a given environment are called the ambient. sound level. Sounds emanate from both man-made sources (
e.g., traffic, aircraft and machinery) and natural sources (e.g.,
I anicals, insects and wind). These sounds can be considered noise; depending upon the loudness, duration, quantity, quality and interrelationship with the listener. A listeners' response I to new noise sources generally is related to the existing ambient sound levels.
level be defined.
Therefore, it is essential that the ambient noise Ambient noise measurements were conducted along with operational noise measurements on September 9, 1989.
The measurements were taken from 12 midnight to 2 AM to ensure I. / capture of the residual (most common minimum) sound level.
I There are many ways to describe ambient sound levels. The most common are the residual, the percentage above (L x) , the energy equivalent (Lea) and the maximum (Laax). The residual sound level is defined as the most common minimum sound level, and is I the baseline for determination of pump noise audibility.
residual description is probably the best to use when assessing a community's annoyance to a new noise source. The Q sound levels The I are those sound levels that are exceeded 'x' percent of the time; the levels used most frequently are L95' L 908 LSO and L10' The L and L levels often are used to define the residual sound evel. he L 50 sound level often is used to define the average sound level in a community and has merit for some daytime assessments. The L io level has been used to assess traffic poise and often is used as the upper noise level in a community, ne-glecting occasional peaks (the opposite of the residual level).
A histogram of sound levels versus occurrence defines the proba-bility function. The L sound level is the level of a continu-I', ous steady noise that has the same energy potential as a varying sound level. A significant problem with USEPA (24-hour) Leq as a I
descriptor is that it is not responsive to very loud sounds of I short duraticn. For example, the noise generated by an airplane flying over a neighborhood or a truck passing would not raise the L e level enough to indicate that these noises were annoying. As l pa9t of the measurement program, the descriptors L95, L 90' L 50' R L 10' hmax and L gq were obtained.
Residual 1/3 octave band noise levels were measured at each sampling location for the purpose of establishing the background broadband noise. Background noise determines the hearing thresh-old for a tone or intrusive noise (i.e., the sound pressure level I at which there is sive noise). The a 50% probability of hearing the tone or intru-residual 1/3 octave band data complies with the requirement of the ASLB ruling LBP-83-ll requiring a determina-tion of the audibility of transformer tones as compared with the I ambient masking level at the nearest residential receptors.
2.1 Selection of Noise Sampling Locations The Bradshaw Reservoir is located in Plumstead Township, Bucks County Pennsylvania, on tne west side of the Delaware River.
I The land surrounding the pumping station is a rural area. There are no industrial noise sources around the station: only small residential developments and scattered farms. The seven sampling i locations were selected so that data collected would best repre-sent noise emissions from the pumping station that neighboring residents would likely hear. A description of each sampling locations are identical to the receptors required for analyses by I the ASLB ruling LPB-83-ll and the recommendation of the NRC staff contained in the environmental statement related to the operation of Limerick Generating Station.
The sampling locations are shown in Figure A. Each is d. eribed in more detail below:
Samplina Locations L-01 is located east of the Bradshaw Reservoir l along Pt. Pleasant Pike, 990 feet from the pump-5 house. This location was chosen to represent the resident who is partially shielded from the trans-3 formers by the pumphouse. Only one of the two g transformers is in the line-of-sight of the resi-dences. The assumption is that this location will receive the effect from one transformer.
E L-02 is also east of the Bradshaw Reservoir along Pt. Pleasant Pike, approximately 1,375 feet from I the pumphouse. As in location L-01, this location represents a resident who is partially shielded from the transformers by the pumphouse.

! L-0$ is established south of the steservoir on Hoyer Road, no loss than 10 foot from the pump house. This location represents the noiso level enissions at the property line.
L-04 is located north of the Bradshaw Reservoir along Bradshaw Road, approximately 1525 foot from I the pumphouso. This site was selected because the pumphouse offers no shielding from the two trans-formers. A direct line-of-sight exists betwoon the sampling location and the equipment. The assumption is that this location will receive the effect from two transformers.
I L-05 is situated 1,150 foot west of the facility, along Moyer Road.

This location is similar to L-L-06 is located southwest of the Bradshaw Resor-voir, approximately 1100 foot along Bradshaw Road.
This point was selected in order to determine what i offect both transformers havo on property south-west of the property.
D L-07 is the final sampling location, situated 380
% foot from the pumphouse at the corner of Moyer Road and Bradshaw Road. This point was selected to dotormino noiso emissions at the property line.
2.2 IllSTRUMENTATION AND CALIBRATION I All acoustical measurements vero made using a Larson-Davis 3100 RTA Integrating Real Time Analyzer. The A-weighting characteris-tics and fast and slow responso of this instrument meet the requirements for precision (Type 1) cound level motors (ANSI
- k. S1.4-1983; IEC 651-1979; and DIN 45 633/1, 1970). Filter charac-5 toristics of the instrument also meet rigid standards (ANSI S1.ll-1966; IEC 225-1966 and DIN 45-652, 1964). Frequency re-sponse of the Larson-Davis 3100 RTA is 2.5 Hz to 20 kH7 in third I octavo bands.
The Larson-Davis 3100 RTA was calibrated by the factory within 6 months of the measurements. Calibration references are traceable to the National Institute of Standards and Technology. Before the measuring period the instrument was calibrated in the field.
All calibration notes woro recorded on the field data sheets by I the individual performing the calibration.
In addition to the sound instrumentation, the survey team was I equf.pped with a portablo wind npeed indicator, compass, thermomo-ter, baromotor and hydromotor, to record meteorological parame-I I
I <
ters at the time of each measurement. To eliminate the bias from I noise generated by wind on the microphone, all measurements vere taken using a protective open cell polyurethane foam windscreen.
l The windscreen does not affect the accuracy of the measurements. ,
During all mecourements calm wind conditions were experienced.
2.3 PERSONNEL I The survey team consisted of Stefanie H. Rath and Glenn C. Winis-torfer, both of United Engineers & Constructors, Inc. They have l
been conducting noise surveys for PECO over the last year. The ;
I project was overseen by Maurice P. Cristoforo, also of UE&C, who holds the title of Consulting Engineer-Acoustics and has over 20 years of experience in designing and performing environmental j
l noise surveys in the power industry. No is affiliated by exam t with the Institute of Noise Control Engineering.

Operaticnal A noise impact assessment, in addition to indicating regulatory I, compliance, should evaluate a community's reaction to the noise produced by a new source. There are many community and environ-g mental noise reting schemes to predict community response to g power plant noise emissions. A community's reaction to a source is based primarily upon a comparison of the new intruding noise with the existing baseline ambient noise levels. The preferred I procedure for rating community response is the Modified Composite Noise Rating (CNR) procedure published in the Edison Ele Institute"ElectricPowerPlantEnvironmentalNoiseGuide".(gric The procedure described in the Guido directs that " level ranking curvec", empirical correction factors, and a cemmunity response curve be used to predict expected community responses to noise produced by a new noise source. " Level ranks" are useful because I.. comparing the A-weighted noise values of two noise sources won't indicate whether or not a particular tonal component of the noise will cause an adverse community response. Using " level ranks" to I predict expected community response lends more consideration to the spectral characteristics of the intruding noise. The " level ranks", based upon the frequency spectrum of the intruding noise, I are corrected for the noise character (continuous, tonal, impul-sive), times of operation, background levels and previous expo-sure by the commt.nity. Figure B represents the " level ranking I curves" on which both baseline ambient noise levels and opera-tional noise levels should be plotted.
corrections to be applied to the plotted level ranks and Figure C Table 3 presents the presents the curve used for predicting expected community re-I sponse from knowing the corrected difference between the baseline ambient noise level and the operational noise level. This curve I

is based o') actual case histories by K. fl . Stevens, et al.(4) l 1 Expected community response to noiso produced by the Bradshaw i
I Reservoir Pumping Facility was predicted to be "No observed I Reaction", using the proceduro outlined above.
Curvos" for the seven locationa are located in Figuros D through J. A review of these figures show high levels of noise in the The "Lovel Rank 2000 and 4000 Hz octave bands which is totally attributable to the sounds of " crickets". This " cricket" noise was not included I in the CNR procedure for a couple of leasons. First, since the noise source is naturally occurring, PECO has no control over it I and residents would not attribute this noise to the facility.
Second, residents will not hold PECO responsible for this natura]
occurring noiso source. Tablo 4 summarizes the results of the modified CNR procedure for the seven sampling locations around the Bradshaw Pumping Station.
Another noise criteria which should be addressed is audibility.
I Audibility of sound has no formal rating procedure, because it would be difficult to sot quantitative limits on audibility as a criterion. However, it is an important attributef peoplo may find the now cound objectionable if it can be heard, regardless l of its 1 because the neighborhood environment has boon I. changed.9gol, )
Tables S thrc2gh 11 present audibility analysos(6)(7) for each of I the novon receptors. The values in these tables demonstrate that, under ideal conditions (no traffic or wind), the Bradshaw Pumping Facilities will not be audible. The higher numbers soon on some of the analyses, again is attributable to the seasonal I " crickets" found in the area.

5.0 CONCLUSION
S The following can be concluded from using the current accepted L methods for predicting the pstential for community annoyance:
- The operation of the Bradshaw Reearvoir Pumping Facility will not exceed the HUD acp interfer-I ence criterion at the seven (7) ..aarest resi-donces, j
- The average expected community responso at the 3 residences nearest the operating facility is "!1o Observed Reaction" based on the preferred " Modi-fiod Composite lloise Rating (CNR) Proceduro" I published by the Edison Electric Institute (EEI Guido).
I
- The potential for annoying sensitive individuals at the nearest residences is remoto.
- The operation of the transformors are inaudible at I all cf f-sito receptors as compared with the audi-bility methodology required by ASLB ruling LBP-93-11 and recommendations of the NRC staff I contained in the Environmental Statement related to the operation of Limerick Generating Station.
