- l. INTRODUCTION Pennsylvania Power and Light Company ( PPL) has sponsored an environmental noise monitoring program at the Susquehanna Steam Electric Station (Susquehanna SES)'since 1972. This is the eleventh report in the series of progress reports that present the results of the environmental noise measurements made in the vicinity of the site. The first seven reports in this series summarize the ambient and construction noise measurements in the
~
years 1972 through 1981. The eighth repor.t presents data obtained with Unit 1 in the operation phase and undergoing testing, and Unit 2 in the latter stages of construction; the ninth report contains the data collected with Unit 1,in operation and Unit 2 in the final stages of construction; and the tenth report transmits the data measured with Unit 1 in operation and Unit 2 in the precommercial operation phase. This report
() summarizes the acoustic data and observations obtained with both Units 1 and 2 in operation. Bolt Beranek and Newman Inc. (BBN) obtained the actest measurements during the weeks of 30 September 2 October and 2'4 October - 27 October 198 5. The purpose of the measurements was to update the acoustic description of t,he community near the site and to provide suf ficient data for the Susquehanna SES Annual Operating Report. ,
BBN employed similar procedures to conduct the 1985 survey as were used in the prior surveys. The field team reviewed the community measurement locations to verify that they continue to represent the noise sensitive land uses in the areas near Susquehanna SES. The dominant noise sensitive land uses near the site remain rural and low density residential housing. Selection of the measurement locations considered the existing on-site and nearby off-site noise sources in addition to topographical barriers. For the purpose of satisfying the requirements of 1

PPL's Environmental Protection Plans (EPP) Non-Radiological, dated 17 July 1982 and 23 March 1984, BBN again selected three locations near the site for primary measurements and two loca-tions farther from the site for secondary measurements. Figure 1 illustrates the current primary and secondary measurement '
locations near the site. PPL purchased the residential prenerty (location 2') that was employed in previous surveys, and therefore, the field team selected a new location (location 2")
on adjacent property to the west for this year's ' survey. In.
addition'to EPP reouirements, the fivs locations distant from the site that were empl,oyed in previous surveys were also retained for supplemental measurements. The supplemental locations are shown on Fig. O-1 in Appendix O.
Both Units 1 and 2 operated at 100% of rated load during the time of 30 September 1985 - 2 October 1985. During 24-27 October 0', 1985, Unit 1 and 2 operated at.100%, except on 26-27 October, when Unit 1 operated at 55% - 98% of full rated load. The water flow rate,for the individual cooling towers was approximately 7000 gpm when each generating unit was ' operating near 100% rated load. During lower load operation of Unit 1, the water flow rate was less than that figure.
Construction of Units 1 and 2 was 100% complete, but con-struction on the emergency diesel generator building was proceeding. This building is located to the east of the service and administration building at the main power block area.
Approximately 100 construction people from outside contractors were working on first shift and none on second or third, shifts.
The construction workers included electricians, carpenters, plumbers, and iron workers. The small concrete. batch plant located on site normally operated three to four hours per week to support construction of the emergency diesel generator tacility.

Report No. 3024A-10 Bolt Beranek and Newman Inc.
A total of 1000 people are employed for the operation of Units 1 and 2. This total includes office and administration, plant operation, and security personnel. This number is expected to increase by about 1000 people during times of scheduled outages, which may last 2 to 3 months. Other than the site traf fic and the construction work described above, little outdoor activity at the plant was observed by the measurement team during
, the survey period.
The we'ather conditions changed during the first measurement visit with clear skies, daytime temperatures of 70* to 75'F and generally light breezes on 30 September and 1 October 1985 yielding to drizzle and rainy condi,tions on 2 October 1985.
During the second measurement visit, the weather improved on the
, late af ternoon of 24 Oc.tober 1985 with rain subsiding and the sky clearing for the balance of the 24-27 October 1985 field visit.
The daytime temperatures were generally 55* - 65'F with inter-mittent periods of gusty breezes for the latter visit.

- o The latest photo of the main power block, taken in August 1984, is presented in Fig. 2.
J The field measurement and calibration techniques employed in, I the September - October 1985 survey were similar to those used in the 1982 - 1984 surveys. Table 1 lists the measurement instruments that the field team used for the 1985 survey and 1
includes their latest laboratory.c,alibration dates. These instruments were selected to be appropriate for. the required field measurements. They conform to applicable standards issued by the American National Standards Institutel,2 (ANSI) and meet
, the Society of Automotive Engineers 3 (SAE) recommended sound data acquisition requirements. Acoustic calibrations that are performed periodically in the laboratory are traceable to the
, National Bureau of Standards (NBS). Figure 3 in a previous ~
) ~
report 4 summarizes the overall check and calibration procedures I'
that are used for each instrument.
At each primary location, the field team obtained 24-hour measurements with a continuous sound level monitoring system.
5 The team also performed hand-held measurements at the primary locations, as well as the secondary locations. These hand-held .
measurements -involved tape recording the sound, noting the I

audible sound sources, and observing the weather conditions during each sampling period at the selected locations. Each sampling period was approximately ten minutes long. After returning from the field, the measurement team analyzed the tape recordings to yield narrowband and octave band sound pressure level and A-weighted sound level data for each time period. In addition to collecting data at the primary and secondary locations, the field team'obtained supplemental hand-held. tape

- 2. SOUND LEVEL MEASUREMENTS AT PRIMARY AND SECONDARY LOCATIONS The field team obtained continuous sound level measurements during 24-hr periods in the community at the primary locations 2", 3, and 4 shown in Fig. 1. The sound levels and sound sources noted- during the 1985 survey are similar to those identified in the previous year's survey. Table'II summarizes the sound level data collected at these locations and presents the L 90' L 10' L eq and the range of sound levels.for the daytime and nighttime periods. The notes below the table explain the various sound level descriptors and how the data were averaged. The daytime L eq sound levels at these locations ranged from 4 4 dB( A) to 51 dB(A), while the nighttime L eq values ranged from 40 dB(A) to 47 dB(A). The table also presents the 24-hr Leq and L dn values and shows the 24-hr L eg ranging from 43 dB(A) 'to 50 dB(A) and the L dn values ranging f rom 4 7 dB( A) to 54 dB(A). The field measurement team observed that the background sound levels were generally controlled by off-site sources, such as insects, and that on-site sources, including . cooling towers, transformers, backup alarms, and paging were sometimes audible. Appendix N identifies specific sound sources together with additional hand-held' tape recorded data.
Figure 1 also shows the secondary measurement locations 5 and 7 where the field team obtained hand-held tape recorded data.
These secondary locations are farther f rom Susquehanna SES than are the primary locations. Table III summarizes the secondary sound level measurements and includes notes on how the data were averaged. The daytime L eq sound levels varied from 48 dB(A) at location 5 to 49 dB(A) at location 7, while the nighttime L eq sound levels decreased at location 5 to 45 dB(A) and at location 7 to 40 dB(A). The 24-hr L eg sound levels were 47 dB( A) at both location 5 and location.7 and the Ldn sound levels were 52 dB(A)
(}
\
at location 5 and 4 9 dB( A) at location 7 The field team I
observed that local sound sources, including insects and traffic, generally controlled the background levels at these locations.

The detailed data obtained from the tape recordings and the field team's identification of sound sources are presented in Appendix N for these secondary measurement locations.
The field team also noted the tonal sounds produced by Susquehanna SES that were audible at of f-site locations. The two sources identified during the survey include the transformers in the southwest switchyard and the cooling towers near the west I
side of the main plant. Figures 3-7 present A-weighted narrow -
band sound pressure level data that were analyzed from selected nighttime tape recordings at the primary and secc: dary measure-i ment locations. Figure 3 illustrates the tonal sound at 107.5 Hz
. produced by the cooling towers and the tonal sounds at 240, 360, i
and 480 Hz produced by the transformers that were measured at location 2". Figur.es 3-7 illustrate other tonal sounds, however, these were masked by other background sounds and were not
) noticeable to the field team during the survey.

- 3. SUPPLEMENTAL SOUND LEVEL MEASUREMENTS During previous surveys at locations quite distant from the
, Susquehanna SES, 'the field tean has conducted supplemental sound level measurements. These measurements were performed to increase the existing data base of background sound levels for
, locations up to five miles from the site. Figure 0-1 in Appendix O shows the supplemental measurement locations where the field team obtained hand-held tape recordings during the 198 5 survey, These recordings were for approximately ten minutes long at each location. The sound pressure level data analyzed from the tapes, the field team's observations of sound sources, and a legend are also presented in Appendix 0 in the same format as Appendix N.

- 4. ASSESSMENT The field team contacted the PPL Special Office of the Presiden t in Berwick, PA during February 1986 to identify and review any community complaints due to plant noise. The Office records indicated that no noise related complaints had been received to date during the operation of Units 1 and of Unit 2 in 1985. Based upon this information, and our acoustic measurements and field observations, we find no reason to re' commend additional noise control treatments at this time.
