{{#Wiki_filter:. survey was attempted under these adverse conditions in the first place and why this approach, using additional predictions for offsite levels, was satisfactory and preferable to conducting the survey at another time when conditions were more acceptable and when the survey could be completed according to the specification. b) If the prediction approach is still proposed by the licensee, the specific noise sensitive land uses around the site must be identified as well as their location relative to the DavisBesse site and its noise sources (as per the ETS Specification). The licensee should provide the predictions of operational noise levels and the bases therefor for these locations using the statistical descriptors mentiorted in the ETS. c) The likely impact of these offsite noise levels should be discussed by the licensee, including as bases the ambient noise levels, the absolute levels. of noise during the operational phase, the increase in noise levels over the ambient levels, the potential for masking of the power plant noises (i.e., considering the frequency spectra of the ambient and operational noises) and the impact, if any, of the possible 125 Hz pure tone f, rom the plant. The licensee should also indicate the noise related complaint history of the plant since operation began. This should include the date and nature of each such complaint-received and the licensee's actual or proposed resolution of the complaint. l 9301060020 821221 PDR ADOCK 05000346 P PDR

- 1. 0 Objectives of the Environmental Protection Plan The Environmental Protection Plan (EPP) is to provide for protection of environmental values during construction and operation of the nuclear facility.
The principal objectives of the EPP are as follows: (1) Verify that the plant is operated in an environmentally acceptable manner, as established by the FES and other NRC environmental impact assessments. (2) Coordinate NRC requirements and maintain consistency with other Federal, State and local requirements for environmental protection. (3) Keep NRC informed of the environmental effects of. facility construction and operation and of actions taken to control those effects. Environmental concerns identified in the FES which relate to water quality matters are regulated by way of the licensee's NPDES permit. O 1-1 -_.,.,.-.___.y__.7..,..-..,_...-.m.;_._.. .. 7
i 2.0 Environmental Protection Issues In the FES-OL dated October, 1975, the staff considered the environmental impacts associated with the operation of the one-unit Davis-Besse Nuclear Power Station. Certain environmental issues were identified which required study or license conditions to resolve environmental concerns and to assure adequate protection of the environment. The Appendix B Environmental Techni-cal Specifications issued with the license included monitoring programs and other requirements to permit resolution of the issues. With the issue of Amendment No. 26 on July 14, 1981, requirements remaining in the ETS related to water quality and aquatic biota are: 1. Protection of the local aquatic ecosystem from sudden temperature changes or excessively high temperature during normal operation. (ETS 2.1) 2. Protection of Lake water quality from effects of chemical releases. (ETS 2.3 and 3.1.1.a.3) 3. Records on chemical usage during station operation. (ETS 3.1.1.a.2) t l 4. Surveillance of biological, chemical, and physical characteristics in the Lake to detect effects of station operation. (ETS 3.1.1.a.1, 3.1.'2.a.1, 3.1.2.a.2 and 4.3) Aquatic issues are now addressed by the effluent limitations, monitoring requirements and the Section 316(b) demonstration requirement contained in the i effective NPDES Permit issued by the State of Ohio Environmental Protection 2-1 -.w. = = -.
Agency. The NRC will therefo e rely on this agency for regulation of 1 matters involving water quality and aquatic biota. Requirements remaining in the ETS related to terrestrial issues are: r 1. Potential impacts on bird populations due to collisions with the cooling tower. (ETS 3.1.2.6.1) 2. Vegetation changes in composition, areal extent and g?neral health of vegetation cover types. (ETS 3.1.2.b.2) \\ Records for the period 1972-1978 show that 221 birds were killed, none belongi'ng i to an endangered species. This number is regarde'd as ' modest and demonstrates i that mortality due to collisions with the cooling tower is,pinimal.

3.0 Consistency Requirements 3.1 Plant Design and Operation The licensee may make changes in station design or operation or perform tests or experiments affecting the environment provided such changes, tests or experiments do not involve an unreviewed environmental question, and do not involve a change in the Environmental Protection Plan.* Changes in plant design or operatien or performance of tests or experiments which do not affect the enviionment are not subject to the requirements of this EPP. Activities governed-by Section 3.3 are not subject to the requirements of this section. Before engaging in additional construction or operational activities which may affect the environment, the licensee shall prepare and record an environmental 1 evaluation of such activity. When the evaluation indicates that such activity / involves an-unreviewed environmental question, the licensee shall provide a written evaluation of such activities and obtain prior approval from the Director, Office of Nuclear Reactor Regulation. When such activity involves a. s change in the Environmental Protection Plan, such activity and change to the Environmental Protection Plan may be implemented only in accordance with an ' appropriate license amendment as set forth in Section 5.3. \\ 4 si A proposed change, test or experiment shall be deemed to involve an unreviewed environmental question if it concerns (1) a matter which may result in a t significant increase in any adverse environmental impact previously evaluated in the final environmental statement (FES) as modified by staff's testimony to

~ the Atomic Safety and Licensing Board, supplements to the FES, environmental impact appraisals, or in any decisions of the Atomic Safety and Licensing Board; or (2) a significant change in effluents or power level [in accordance with 10 CFR Part 51.5(b)(2)] or (3) a matter not previously reviewed and evaluated in the documents specified in (1) of this Subsection, which may have a significant adverse environmental impact. The licensee shall maintain records of changes in facility design or operation and of tests and experiments carried out pursuant to this Subsection. These records shall include a written evaluation which provide bases for the deter-mination that the change, test, or experiment does not involve an unreviewed environmental question nor constitute a decrease in the effectiveness of this EPP to meet the objectives specified in Section 1.0. The licensee shall include as part of his Annual Environmental Operating Report (per Subsec-tion 5.4.1) brief descriptions, analyses, interpretations, and evaluations of such changes, tests and experiments. 3.2 Reporting Related to the NPDES Permits and State Certifications Violations of the NPDES Permit or the State certification (pursuant to Section 401 of the Clean Water Act) shall be reported to the NRC by submittal of copies of the reports required by the NPDES Permit or certification. Changes and additions to the NPDES Permit or the State certification shall be reported to the NRC within 30 days following the date the change is approved. If a permit or certification, in part or in its entirety, is appealed and stayed, the NRC shall be notified within 30 days following the date the stay is granted. i 3-2 j
The NRC shall be notified of changes to the effective NPDES Permit proposed by the licensee by providing NRC with a copy of the proposed change at the same time it is submitted to the permitting agency. The notification of a licensee-initiated change shall include a copy of the requested revision submitted to the permitting agency. The licensee shall provide the NRC a copy of the application for renewal of the NPDES permit at the same time the application is submitted to the permitting agency. 4 3.3 Changes Required for Compliance with Other Environmental Regulations Changes in plant design or operation and performance of tests or experiments which are required to achieve compliance with other Federal, State, or local environmental regulations are not subject to the requirements of Section 3.1. 1 O f 3-3 [ k._.
4.0 Environmental Conditions 4.1 Unusual or Important Environmental Events Any occurrence of an unusual or important event that indicates or could result in significant environmental impact causally related to plant operation shall be recorded and promptly reported to the NRC within 24 hours by telephone, telegraph, or facsimile transmissions followed by a written report per Subsection 5.4.2. The following are examples: excessive bird impaction events, onsite plant or animal disease outbreaks, mortality or unusual occurrence of any species protected by the Endangered Species Act of 1973, fish kills, increase in nuisance organisms or conditions and unanticipated or emergency discharge of waste water or chemical substances. No routine monitoring programs are required to implement this condition. 4.2 Vegetation Survey - Aerial Remote Sensing Vegetative communities of the site and vicinity within 1 kilometer of the cooling tower in all directions shall be aerially photographed annually to detect and assess the significance of damage, or lack thereof, as related to cooling tower drift dispersions. Photography shall be done by aerial over-flight during later summer prior to natural senescence of the plants. Timing of aerial photography and determination of ground truth shall be selected to coincide with periods of maximum predicted drift deposition damage. Monitoring shall include a program of low altitude false color aerial photography. The scale for full coverage shall be adequate to 4-1 ,m._,__,,,__.
enable identification of vegetative damage over relatively small areas of terrain. Some circumstances may warrant inspection of photographs discerning individual trees. Such scale should be in the interval between 1:1000 and 1:12,000 as appropriate to resolve impacted features. Photographic interpretations shall correlate data from ground truth or ground inspection surveys with areas of stress and non-stress as seen on the photographs for purposes of verification of results and interpretations. Ground truth surveys shall cover, but n'ot be limited to, the first two years of aerial photographic monitoring program. Two years of data irom the sur-veillance program have now been reported and have not indicated any impact due to the cooling tower. The frequency of sampling can therefore be reduced to once every other year. After two such reports the licensee may request modification or termination of this monitoring requirement per Subsection 5.3. Description of the program, results, and interpretive analyses of environmental impacts shall be reported in accordance with Subsection 5.4.1. Results reported shall contain information encompassing but not limited to: sampling data; time of day; film type; spectral bands; and one set of resultant color transparancies encompassing an area within approximately one kilometer radius of the cooling tower. i 4-2 l __,___......,.r__
4.3 Operational Noise Surveillance The objective of this program is to conduct a noise survey in the vicinity of the Davis-Besse site during normal unit operation. The results of the survey shall be used to assess the noise impact of the operation of Unit No. 1. In devising the methodology to be used during the operational noise survey, consideration shall be given to ANSI S3W50(1) which establishes a method for the evaluation of noise in an area in which the ambient sound levels result from the superposition of multiple noise sources. The survey periods and the number of sampling points in the survey area shall be chosen in order to develop a statistical statement of the noise levels in the vicinity of the site. During the survey, n,oise sensitive ' nd "m and specific noise sources shall be identified. Measurements shall be obtained near cri-tical locations of noise sensitive land use such as the nearest resident, school, hospital, cemetary, and wildlife refuge which may be affected by noise from unit operation. Measurements shall be obtained in the vicinity of the unit during the hours of daytime (0700-1900 hours), evening (1900-2200 hours), and nighttime (2200-0700 hours) over a two day period during representative environmental conditions and while Davis-Besse Unit No. 1 is operating at full load within one year after the unit has achieved operation at rated load. The survey shall be conducted during a period when the construction activities associated with the Davis-Besse site shall be minimal and do not contribute significantly to the noise levels. The instrumentation which shall be used during the operational noise survey shall consist of the following: i 4-3
1. Bruel and Kjaer Type 2209 Precision Sound Level Meter 2. Bruel and Kjaer Type 1613 Octave Filter Set 3. Bruel and Kjaer Type 4145 Condenser Microphone 4. Bruel and Kjaer Type 4420 Pistonphone This instrumentation meets the requirements of the International Electro-technical Commission (IEC) for a Type I or precision sound level meter.(2) A 1-inch diameter condenser microphone shall be used to assure that accurate low ambient sound level measurements can be made. The meter shall be acoustically calibrated using the B&K Pistonphone before and after each measurement period to assure continf accuracy. All measurement shall be made using an open-celled polyurethane foam wind screen to attenuate the effect of wind generated noise. Headphones shall be used to determine any distortion, improper application characteristics, and intermittent electrical connections. Sound level measurements shall be made with the precision sound level meter operated in the A-weighted slow response mode. The field measurements shall conform to the recommendations of ANSI S3W50 except for Paragraph 2.2, " Instrument Reading Procedures". This paragraph states that one should observe the A-level reading for five seconds and record the best estimate of the cen-tral tendency and the range of the meter deflections, with observations repeated until the number of readings equals or exceeds the spread (in decibels) of l all the readings. This method was modified, based on experience at other sites, 1 j because large fluctuations of the readings due to local sources such as rust-t ling leaves and creatures of nature will not permit a central tendency to be determined with a five second period. The method to be used involves the 1 4-4 l ~ ~ = - - -. -
observation of the meter once every five seconds regardless of the location of the needle within its swing. These measurements are repeated until a satis-tically reliable sample is obtained. The number of readings required to achieve this condition is determined by the variability of the ambient sound level, which in most cases consists of at least 100 readings that are recorded at each sampling point during each measurement period. The measurement approach of taking a sample every five seconds results in a statistically independent sample because the interval is considerably greater than the meter averaging time. Octave band analyses shall be obtained to assess the nature of any complex noise source or to identify the presence of any pure tone associated with the operation of Davis-Besse Unit No.1. Meteorological conditions during the survey shall be documented by cbtaining hourly readings of the wind speed, wind direction, temperature, temperature lapse rate (aT), and dew point from the onsite meteorological tower. Supple-mental data such as barometric pressure shall be obtained from nearby airports. The operating conditions of Davis-Besse Unit No. 1 during the survey shall be documented by obtaining hourly readings of the steam flow rate, power output (MWe), circulating water flow through the natural draft cooling tower, and supporting operating data. The data obtained during the noise survey shall be analyzed with the NUS computer code DBFRE to obtain the A-weighted L10, L50' '90' leg, and Ldn sound 4-5 ,.._._...,_2._. ,_... - ~ .,m, n c-

sound levels (sound levels exceeded 50% of the time) at each sampling point 50 shall then be used to construct A-weighted sound level contours on a site map. Operational Noise Impact Assessment The results of the noise survey during unit operation shall be compared to the pre-operational background noise levels documented in Section 2.9 of the Davis-Besse Unit No. 1 Supplement to the Environmental Report - Operating License State and several noise level criteria to assess the final operational noise impact of Davis-Besse Unit No. 1. These results shall also provide a check on the predicted noise impact of the operation phase presented in Section 5.7 of the Davis-Besse Unit No. 1 Supplement to the Environmental Report - Operating License Stage. Consideration shall be given to several noise level criteria in evaluating the final noise impact of the operation phase. The HUD Noise Criteria ( ) states that sound levels up to 45 dBA are " acceptable" for continuous 24-hour exposure; levels up to 65 dBA are "normally acceptable" provided th'at 65 dBA is not exceeded more than 8 hours per day; levels exceeding 65 dBA more than 8 hours per day are "normally unacceptable"; and levels which exceed 75 dBA more than 8 hours per day or 80 dBA more than 60 minutes per day are " unacceptable." l The EPA proposed noise level guidelines (4) state that in residental environments, the time weighted day / night outdoor average level, below which 4-6 -..c.__,_.-,__,._. _....._....___.__...,__._._....-,__,._,___.m__..y
5 no effects on public health and welfare occur due to activity or speech-interferences, is 55 dBA. Such levels would also protect the majority of the exposed population under most conditions against annoyance. Stevens, Rosenblith, and Bolt (5) suggest another method that compares the background noise levels with the intruding noise. Since its introduction, this method has been shown to be valid by the results of additional studies, and it is an approach commonly used by acousticians. It indicates that up to a 5 dBA increase in the ambient will usually not generate any complaints due to annoyance. Up to a 10 dBA increases may cause a slight amount of annoyance. REFERENCES 1.
