NOISE LEVELS: The A-weighted sound pressure level resulting from the operation of equipment furnished under these specifications (including drive motors) shall not exceed a free-field spatial arithmetic average (per piece of equipment) of 85 dBA along the equipment envelope at a height of 5 feet above the ground and personnel platforms. The equipment envelope is the perimeter line that completely encompasses the equipment package (including noise control devices) at a distance of 3 ft from the equipment face. 4.1 Noise Testing Methods: During commissioning, when the facility is in full operation, the Buyer shall, at its own discretion, conduct noise testing to establish the equipment noise emissions. The noise emissions test shall be conducted in accordance with the test protocol detailed herein as adapted from industry standards including NOM-011-STPS-2001, ANSI B133.8, ANSI/ASME PTC 36, ANSI S1.13, and ANSI S12.18. The Seller shall be notified prior to the survey and given the opportunity to witness the testing. The survey shall be conducted by personnel who are qualified through experience or training to conduct industrial facility noise surveys. 4.2 Measurement Instrumentation: All sound level measurements shall be conducted using a sound level meter that meets the requirements of ANSI S1.4. The sound level meter shall be equipped with integrating capabilities to determine the average sound levels over a specified duration. For all measurements, the microphone shall be equipped with a windscreen provided by or recommended by the sound level meter manufacturer. If necessary, the microphone shall be mounted on a tripod to maintain stability. 4.2.1 The sound level meter shall be field calibrated immediately before and after each measurement series and after any major change in equipment conditions such as rough handling, becoming wet, etc. Field calibration shall be conducted using a precision calibrator and each calibration level shall be recorded. A change in calibration level exceeding +/- 1.0 dB may require that the measurement series be repeated. 4.2.2 The sound level meter equipment and calibrator shall have been laboratory calibrated within the 12 months prior to the testing. All equipment calibration certificates shall be available during the survey and copies shall be included with the final survey report. 4.3 Measurement Conditions: Any variation from the rated load shall be noted. Equipment that is not typically required for normal facility operation shall not be operating during the surveys. All equipment enclosures shall be fully installed and all doors and openings shall be closed.

All Rights Reserved. granularity=word contentanalysis={punctuationbreaks=false dehyphenate=false} layoutanalysis={tabledetect=0 layoutdetect=0} 4.3.1 Outdoor sound level measurements shall not be conducted during adverse weather conditions or conditions which may damage the instrumentation. Measurements should be avoided during periods when the average wind speed exceeds 7 mph measured 5 feeth above the ground or platform. Measurements during excessive wind speeds shall be noted on the data sheets. Measurements shall not be conducted during periods of precipitation or wet surface road conditions if such conditions increase the background noise. Weather conditions shall be noted on the measurement data sheets. 4.4 Environmental Sound Level Survey: If local conditions such as background noise, accessibility, reflecting surfaces, screens, topographical conditions, or other restrictions preclude meaningful measurements at the measurement locations, alternate locations may be selected provided proper corrections are made in accordance with the referenced standards. The exact locations shall be determined at the time of testing. The background and operational measurements shall be taken at the same measurement locations. The microphone shall be positioned approximately 5 ft above the ground for all measurements. 4.4.1 The sound level survey shall include operational sound level measurements at the prescribed locations during normal operation of the equipment. All non-equipment noise sources that are audible during the measurement period shall be noted on the data sheets. The sound level survey shall include background sound level measurements at each operational measurement location during a period when the equipment is completely shut down. The background sound level measurements shall be conducted during a period that experiences ambient conditions similar to the background conditions experienced during the operational measurements. 4.4.2 P\Y gcibX `YjY` aYUgifYaYbhg g\U`` ]bW`iXY h\Y -octave band 90-percentile exceedance sound level, L90. The duration of the measurement shall be sufficiently long to capture a representative sound level at the measurement location. All sound level measurements shall be recorded during a period of minimal background influence, i.e. between vehicle passes, aircraft flyovers, train passes, and other discrete non-facility sources. The measurement may be paused during such discrete noise sources if necessary to achieve the minimum measurement period. 4.4.3 Background sound level measurements shall be deemed unnecessary if the operational measurements, without any corrections for background noise, are equal to or less than the noise criteria. Additionally, if representative background sound level measurements indicate that the background sound levels are at least 10 dBA below the operational sound levels, the influence of the background noise shall be deemed negligible and further background sound level measurements shall not be necessary. If the measured background sound level is not at least 3 dBA below the measured operational sound level, alternate measurements may be conducted. Alternate measurements may include conducting measurements at locations closer to the equipment (within the far-field) or during periods when the background noise is lower. The alternate measurements should provide background sound levels that are at least 3 dBA lower than the operational sound levels. If the measured operational sound level does not exceed the measured background sound level by at least 3 dBA and alternate measurements were not available as previously described, the operational sound level shall be deemed not to be contributing to the background. Thus, the equipment sound pressure level shall be assumed to be 10 dBA below the Homer City Generation Kiewit Project No. 20059040 GR-A-5 Published: 06/12/2025 Kiewit Confidential & Proprietary Information.

Following the background correction, the equipment sound level at all measurement locations that are not at the prescribed receptor location shall be corrected in accordance with the referenced standards for the distance to the receptor location. 5.
