Introduction The following report provides a noise modeling assessment of the proposed equipment at the Latham Compressor Station operated by Rocky Mountain Midstream in relation to the Colorado Revised Statutes (CRS) 25- 12- 103 noise regulations. The Latham Compressor Station (40°22' 17.41 "N, 104°38'53 .91 " W) is located 0.55 miles southwest of the intersection between Weld County Roads 45 and 54 in Auburn, Colorado. Single-family residentials are located north, east, south and west of the site. Figure 1 - 1 identifies the site location . To assess the predicted noise levels of the proposed compressor station, manufacturer sound level performance data of equipment, exhaust silencers, and acoustical buildings was used. The noise model was developed using SoundPLAN 8.0 software. The following is provided in this report: • A brief introduction of the fundamentals of noise. • A review of the applicable CRS 25- 12- 103 noise standards. • A discussion of the noise modeling methodology and results. r _ , - . . sit / ,i. ,,, i , ars. me lir , is :is lini : egallik C: I i , Him,. r Latham Compressor ♦ � ' Station f r "PIS Z.

Noise Fundamentals Sound is most commonly experienced by people as pressure waves passing through air. These rapid fluctuations in air pressure are processed by the human auditory system to produce the sensation of sound . The rate at which sound pressure changes occur is called the frequency . Frequency is usually measured as the number of oscillations per second or Hertz ( Hz) . Frequencies that can be heard by a healthy human ear range from approximately 20 Hz to 20.000 Hz. Toward the lower end of this range are low-pitched sounds, including those that might be described as a "rumble" or "boom" . At the higher end of the range are high -pitched sounds that might be described as a "screech" or "hiss" . Environmental noise generally derives, in part, from a combination of distant noise sources. Such sources may include common experiences such as distant traffic . wind in trees, and distant industrial or farming activities . These distant sources create a low- level " background noise" in which no particular individual source is identifiable. Background noise is often relatively constant from moment to moment, but varies slowly from hour to hour as natural forces change or as human activity follows its daily cycle . Superimposed on this low- level , slowly varying background noise is a succession of identifiable noisy events of relatively brief duration . These events may include the passing of single -vehicles, aircraft flyovers, screeching of brakes, and other short-term events. The presence of these short-term events causes the noise level to fluctuate. Typical indoor and outdoor A -weighted sound levels are shown in Figure 2- 1 . Detailed acoustical definitions have been provided in Appendix A — Glossary of Acoustical Terms.

CRS 25 - 12 - 103 Noise Standards The modeling analysis was developed to predict operational noise levels at adjacent properties and verify compliance of operations with the CRS 25 - 12 - 103 noise standards . The CRS code establishes permissible sound levels by type of property and hours of the day . The measurement location is defined in Section 25 - 12- 103 ( 1 ) as "Sound levels of noise radiating from a property line at a distance of twenty -five feet or more therefrom in excess of the dB(A ) established for the following time periods and zones shall constitute prima facie evidence that such noise is a public nuisance Based on the specifications of the CRS 25 - 12- 103 code, the Commercial noise level limits listed in Table 3 - 1 will be used throughout the report in accordance with the Developmental Standards .

Latham Compressor Station Noise Modeling 4. 1 Noise Modeling Methodology The noise modeling was completed with use of three-dimensional computer noise modeling software. All models in this report were developed with SoundPLAN 8.0 software using the ISO 9613-2 standard. Noise levels are predicted based on the locations, noise levels and frequency spectra of the noise sources, and the geometry and reflective properties of the local terrain, buildings and barriers . The predicted noise levels represent only the contribution of the proposed compressor station operations and do not include noise from other facilities . Actual field sound level measurements may vary from the modeled noise levels due to other noise sources such as traffic, other facilities, other human activity, or environmental factors. The predicted noise levels were supplemented with ambient noise levels measured at the site. The ambient sound level data was sourced from an ambient sound level survey conducted at the site between Friday, October 12 to Monday, October 15 , 2018 and submitted to Rocky Mountain Midstream on October 23 , 2018 . Noise levels are expressed in decibels, which is a logarithmic scale, therefore, the ambient noise level was added to the predicted noise levels logarithmically. The equipment sound level data used in the Latham Compressor Station modeling was sourced from equipment manufacturer data per approved project design documentation . The modeling results predicted are dependent on equipment and mitigation orientation as indicated per provided project documentation . Table 4- 1 lists the sound power levels of the modeled equipment. Table 4-2 shows the transmission or insertion loss data for the acoustical enclosure surrounding, the compressor skids, the permanent sound wall and proposed equipment modifications. 4.2 Noise Sensitive Receptors The noise sensitive receptors have been chosen to be consistent with the requirements of the CRS 25- 12- 103 noise standards . The requirements indicate that sound levels of noise radiating from a property I i ne at a distance of twenty - five feet or more therefrom in excess of the dB(A) established for the following time periods and zones shall constitute prima facie evidence that such noise is a public nuisance . As such, receptor locations were chosen at 25 ft. from the USR boundary of the Latham Compressor Station Facility to represent potential regulatory measurement points should a complaint be made. Figure 4- 1 shows the A - weighted noise sensitive receptor locations. Latham Compressor Station Noise Modeling 6 Behrens and Associates , Inc .

Environmental Noise Control 4. 3 Noise Modeling Results Two modeling scenarios were created to investigate various options at the proposed site and are described in Table 4-3 . The results of the noise modeling are presented in Table 4-4. Table 4-5 shows the predicted noise modeling results when ambient is considered . The locations in the tables correspond to the receptor locations identified in Figure 4- 1 . The results of the noise modeling are also shown as noise contour maps. Figure 4-3 shows the Scenario 1 Noise Contour Map in dBA and Figure 4-4 shows the Scenario 2 Noise Contour Map in dBA . The noise contours are provided in 5 dB increments with the color scale indicating the sound level of each contour. The proposed Latham Compressor Station layout is shown in Figure 4-2. Table 4-3 Modeled Scenarios Modeled Scenario Description Baseline — Compressor skids are modeled with specified MAXIM engine exhaust Scenario 1 silencers; compressor skids are enclosed in acoustical buildings with STC-40 rated walls and roof; additionally, Harsco 180-2Z coolers, an FMC M12 condensate pump and two VRG Controls PRCV-STHP valves are modeled. Mitigated — Compressor skids are modeled with modified MAXIM engine exhaust silencers with a minimum insertion loss per Table 4-2, modified Harsco 180-2Z coolers and includes 200 total linear feet of 15 -foot-high permanent acoustical wall Scenario 2 with a Sound Transmission Class (STC) rating of at least 40 installed on the western and eastern perimeter of the site nearest the compressor skids and coolers ; compressor skids are enclosed in acoustical buildings with STC-40 rated walls and roof; the FMC- M 12 condensate pump is surrounded with an 8-foot-high permanent sound wall with an STC-40 rating. The noise modeling results for Scenario I indicate that the proposed operations of the Latham Compressor Station are predicted to exceed the allowable CRS noise limits at all modeled receptor locations by as much as 15 . 7 dBA . The measured ambient noise level near the site is more than 10 dBA lower than the Scenario 1 predicted noise levels at all modeled receptors, therefore, the effect of ambient noise on Scenario 1 predicted noise levels is insignificant. The noise modeling results for Scenario 2 indicate that with implementation of the recommended mitigation measures outlined in Table 4-3 , the proposed operations of the Latham Compressor Station are predicted to comply with the allowable CRS noise limits at all modeled receptor locations. The measured ambient noise level near the site is less than 10 dBA lower than the Scenario 2 predicted noise levels at all modeled receptors, therefore, the Scenario 2 predicted noise levels are expected to increase by as much as 0. 7 dBA when ambient is considered.

Environmental Noise Control1\1\ l‘ JV 5 . Conclusion Predictive noise models were created to represent the proposed operations at the Latham Compressor Station operated by Rocky Mountain Midstream . Manufacturer sound level performance data of equipment, exhaust silencers, and acoustical buildings was used in the models to asses to noise impact. Noise sensitive receptor locations included in the modeling were placed in accordance with the applicable noise standards of CRS 25 - 12- 103 and the Developmental Standards Based on the modeling results of the Latham Compressor Station, our analysis indicates that the baseline predicted noise levels will exceed the allowable nighttime noise limit of 55 dBA at all receptor locations. With implementation of the recommended mitigation measures outlined in Table 4-3 , all modeled receptor locations are predicted to comply with the CRS maximum permissible daytime and nighttime dBA limits.

Ippf Environmental Noise Control Ambient Noise The all -encompassing noise associated with a given environment at a specified time, usually a composite of sound from many sources both near and far. Average Sound Level See Equivalent-Continuous Sound Level A-Weighted Decibel Scale The human ear is more sensitive to some sound frequencies than others . It is therefore common practice to apply a filter to measured sound levels to approximate the frequency sensitivity of the human ear. One such filter is called the A-weighted decibel scale which emphasizes sounds between 1 , 000 and 5 ,000 Hertz by discounting the frequencies outside of this range . As the human ear is less sensitive to low frequency noise, the A-weighted decibel scale begins to increasingly discount noise below 500 Hertz. Measurements conducted utilizing the A-weighted decibel scale are denoted with an "(A )" or "A " after the decibel abbreviation ( dB ( A ) or dBA ). The A-weighted scale is nearly universally used when assessing noise impact on humans. Community Noise Equivalent Level ( CNEL) A 24-hour A-weighted average sound level which takes into account the fact that a given level of noise may be more or less tolerable depending on when it occurs . The CNEL measure of noise exposure weights average hourly noise levels by 5 dB for the evening hours (between 7 : 00 pm and 10 : 00 pm), and 10 dB between 10 : 00 pm and 7 :00 am, then combines the results with the daytime levels to produce the final CNEL value . It is measured in decibels, dbs . Day- Night Average Sound Level (Ldn ) A measure of noise exposure level that is similar to CNEL except that there is no weighting applied to the evening hours of 7 :00 pm to 10 :00 pm . It is measured in decibels, dB . Daytime Average Sound Level The time-averaged A -weighted sound level measured between the hours of 7 : 00 am to 7 : 00 pm . It is measured in decibels, dB . Decay Rate - The time taken for the sound pressure le \ el at a given frequency to decrease in a room . It is measured in decibels per second, dB/s . Decibel (dB) The basic unit of measurement for sound level . Direct Sound Sound that reaches a given location in a direct line from the source without any reflections . Glossary of Acoustical Terms 15 Behrens and Associates , Inc . Environmental Noise Control Divergence The spreading of sound waves from a source in a free field, resulting in a reduction in sound pressure. level \\ ith increasing distance from the source. Energy Basis This refers to the procedure of summing or averaging sound pressure levels on the basis of their squared pressures. This method involves the conversion of decibels to pressures, then performing the necessary arithmetic calculations, and finally changing the pressure back to decibels. Equivalent-Continuous Sound Level (Leq) The average sound level measured over a specified time period . It is a single-number measure of time - varying noise over a specified time period . It is the level of a steady sound that, in a stated time period and at a stated location . has the same A - Weighted sound energy as the time-varying sound . For example, a person who experiences an Leq of 60 dB(A) for a period of 10 minutes standing next to a busy street is exposed to the same amount of sound energy as if he had experienced a constant noise level of 60 dB(A ) for 10 minutes rather than the time-varying traffic noise level . It is measured in decibels, dB . Fast Response A setting on the sound level meter that determines how sound levels are averaged over time . A fast sound level is always more strongly influenced by recent sounds, and less influenced by sounds occurring in the distant past, than the corresponding slow sound level . For the same non-steady sound, the maximum fast sound level is generally greater than the corresponding maximum slow sound level . Fast response is typically used to measure impact sound levels . Field Impact Insulation Class (FIIC) A single number rating similar to the impact insulation class except that the impact sound pressure levels are measured in the field .

Insertion Loss The decrease in sound power level measured at the location of the receiver when an element (e .g., a noise barrier) is inserted in the transmission path between the sound source and the receiver. Inverse Square Law A rule by which the sound intensity varies inversely with the square of the distance from the source . This results in a 6dB decrease in sound pressure level for each doubling of distance from the source . Ln Percentile Sound Level The noise level exceeded for n% of the measurement period where n is between 0 . 01 % and 99 .99%. Usually includes a descriptor i . e . A-weighting. Common Ln values include LA10, LA50, and LA90 levels. LA10 \N. ou Id represent the A -weighted sound level that is exceeded for 10% of the measurement period.

Octave- Band Sound Level For an octave frequency band , the sound pressure level of the sound contained w, ithin that band . O ne-Third Octave The frequency interval between two sounds whose frequency ratio is 2^( 1 /3 ) . For example, the frequency interval between 200 Hz and 250 Hz is one-third octave . O ne-Third -Octave-Band Sound Level For a one-third-octave frequency band, the sound pressure level of the sound contained within that band .

Harsco 180-2Z coolers . an FMC M12 condensate pump and two VRG Controls PRCV -STHP valves are modeled . Mitigated — Compressor skids are modeled with modified MAXIM engine exhaust silencers with a minimum insertion loss per Table 4- 2 . modified Harsco 18O-2Z coolers and includes 1 . 210 total linear feet of 15 - toot -high permanent acoustical wall with a Sound Transmission Class ( STC) rating of at least 40 installed on the western . Scenario easternand southern perimeter of the site : compressor skids are enclosed in acoustical buildlllggs with STC -40 rated walls and root : the FMC-M12 condensate pump is surrounded with an 8 -foot-high permanent sound wall with all STC -40 rating : Coordination with the valve vendor is advised to select pipe lagging for installation upstream and downstream of each VRG Controls PRCV-STHP valve which achieves at least a 5 dBA reduction in valve noise . The noise modeling results for Scenario 1 indicate that the proposed operations of the Latham Compressor Station are predicted to exceed the allowable CRS noise limits at all modeled receptor locations by as much as 20 . 7 dBA. The measured ambient noise level near the site is more than 10 dBA lower than the Scenario 1 predicted noise levels at all modeled receptors . therefore . the effect of ambient noise on Scenario I predicted noise levels is insignificant . The noise modeling results for Scenario 2 indicate that with implementation of the recommended mitigation measures outlined in Table 4-3 . the proposed operations of the Latham Compressor Station are predicted to comply with the allowable CRS noise limits at all modeled receptor locations . The measured ambient noise level near the site is less than 10 dBA lower than the Scenario 2 predicted noise levels at all modeled receptors . therefore . the Scenario 2 predicted noise levels are expected to increase by as much as 1 . 9 dBA when ambient is considered .
