RE : Speakman A Booster Compresso r NTC #7
Dear Mr. Hartmann,
792 Buckhorn Drive
Rifle, CO 81650
Per our phone conversation, the noise analysis was conducted by Robert Bleil, Dwayne
Knudson, Dave Haye s, Ursa Operating Company LLC and peer reviewed by Ken Kreie, Olsson
Associates. The noise readings provided in Exhibit A were taken by Dave Hayes, who has one
year of experience with our noise monitoring equipment and has conducted over 100 noise
readings. Ken Kreie 's credentials were attached to the original application, which shows six
years' experience in noise control regulation compliance.
In the NTC Response dated March pt, it was stated the "project noise levels for the proposed
booster at 350 feet would be 45 .2 dBA; which is within COGCC's most restrictive standard of 50
dBA for rural/residential". The projected noise at 350' with proposed single compressor was
ca lculated by using the existing 350' S data (47.5 dBA) minus 5% which is the average difference
between the existing compressors and the proposed sing le compressor (47 .5 x 0.95 = 45.125).
The average difference of 5% was calculated by subtracting the AXIP data from the Ursa data to
equal the reading variations (87.07-88 .8 = -1.73). The percentage of difference was calculated
by dividing the reading variation by the AXIP average (-1 .73/87.07= -2%).
The existing six compressors are under the SOdBA therefore we anticipate the proposed single
compressor will be under the SOdBA as well. However Ursa is proposing sound wall mitigation
using an STC -40 sound wall to further reduce the potential for sound impacts to the
community.
Please let me know if you have any further questions.

4-203.G.7 – Sound Data Review
Ursa Operating Company
Speakman A Booster Compressor
At the request of Ursa Operating Company (Ursa), Olsson Associates (Olsson) has conducted an
assessment of noise survey data. This assessment included survey data provided by Ursa and
collected by Principle Environmental, LLC. The data set was collected at an existing facility where
a booster compressor, identical to the one proposed for installation at the Speakman A, is
installed. The purpose of this review is to assess the expected noise level that will be generated
by the operation of the proposed booster compressor. Olsson used the existing noise level data
and calculated the expected noise levels extrapolated out to the compliance point distance.
Olsson provided an explanation of the anticipated noise levels with the new compressor and how
they compare to the compliance limit set forth in the Colorado Oil and Gas Conservation
Commission (COGCC) Rule 802.
Noise Data
The set of data that was reviewed was included in the Noise Signature Study Report for the
Apache Bay City Compressor Station prepared by Principle Environmental, LLC. This data was
collected in the vicinity of the operation of a 7044 Booster Compressor, identical to the equipment
proposed to replace the existing wellhead gas lift compressors. The Noise Signature Study
Report is attached to this report as Attachment A.
Noise Generating Equipment
One 7044 Booster Compressor in full operation at the Apache Bay City Compressor Station
located in Matagorda, Texas. This compressor is identical to the equipment proposed for
installation at the Speakman A location. Therefore the noise levels provided have been used to
draw conclusions about the anticipated noise levels at the Speakman A location.
Compliance Point(s)
The COGCC Rule 802 uses the property line or 350 feet from the noise generating equipment,
whichever is greater, as the compliance point for oil and gas operations. The nearest property
boundary from the proposed Booster Compressor location is approximately 375 feet to the south
of the facility. Therefore Olsson has used 375 feet away from the noise generating equipment as
the compliance point.
In addition to the distance representing the compliance point, Olsson has also calculated the
sound pressure levels at the following distances from the noise generating equipment to
determine what the sound pressure levels may be at various locations near the equipment.
800 feet, equal to the approximate distance to the western property boundary
950 feet, equal to the approximate distance to the northwestern property boundary
1425 feet, equal to the approximate distance to nearest occupied structure located to the
west and distance to property boundary towards the northeast

1575 feet, equal to the approximate distance to nearest occupied structure located to the
north
1725 feet, equal to the approximate distance to the subdivision located to the northeast.
Maximum Permissible Noise Levels
Garfield County is applying the Residential/Agricultural/Rural noise standard, as prescribed in
COGCC Rule 802.b.(2). The night time maximum permissible noise limit is 50 dB(A) for residential
areas. This sound pressure limit has been used to determine if the proposed Booster Compressor
would be a nuisance at the property lines and nearby occupied structure(s).
Calculated Sound Pressure Levels
The average sound pressure level of the booster compressor calculated from the noise survey
data is 58.3 dB(A) at 375 feet. Olsson has assessed the potential noise level at a range of
distances using the noise/distance extrapolation equation provided in COGCC Rule 802. This
data is summarized in Table 1.
Conclusion
By utilizing the sound readings collected from identical equipment currently operating at an offsite
location, we can estimate the sound pressure levels that would be generated from similar
equipment operated at the Speakman A facility. The actual sound pressure level measurements
collected at the Apache Bay Compressor Station facility can be extrapolated to the distance of
the compliance point and the distances to nearby occupied structures.
Unmitigated, the extrapolated sound pressure level average at the southwest and northwest
property boundaries exceed the 50 dB(A) limit. However, the simple extrapolation equation used
to calculate these noise levels does not account for the topography of the site. The facility
topography and grading is such that the actual noise levels to the south and west will be greatly
reduced. In addition, there are no existing occupied structures at the property boundaries in these
directions.
The calculated noise levels exceed the allowable nighttime noise limit under COGCC Residential
limit at a distance of 350 feet and at some of the property boundaries. In order to mitigate potential
sound levels which could impact nearby residences, an acoustical barrier will be installed along
the northeast and a portion of the northwest sides of the compressor. The proposed STC-40
Rated MMA Barrier is shown on the attached report (Attachment B).The site topography and
grading will act as a barrier along the sides of the compressor where no acoustical barrier is being
installed. The site topography and grading is shown on the Speakman A Pad Site Plan
(Attachment C).
With the sound wall in place, sound pressure level averages at all nearby occupied structures are
estimated well below the 50 dB(A) limit.
The sound pressure levels extrapolated for the Speakman A site are calculated and actual noise
levels will vary. The actual sound pressure levels will be measured during equipment operation
to ensure compliance with COGCC Rule 802.

from noise signature studies can be used to determine noise power levels for the 7044
Compressor. Once the power levels of the equipment are determined, they can be used to
generate predictive sound models of the site. The sound models are generated using Datakustik
CadnaA version 4.3.143 software program and predict the propagation of sound generated from
the equipment. CadnaA analyzes the power levels and height of the drilling sound sources and
takes into account the topography of the land in order to accurately predict sound levels at nearby
protected use structures.
Principle conducted the monitoring at the site on Wednesday, August 6, 2014. Several
monitoring locations were chosen around the 7044 Compressor operation in order to fully
document the noise signature of the operation. The monitoring points are shown in the figure
below and also in the photographs provided in Attachment 1. Two compressor are shown in the
figure below, but only the unit that is south of the pad was running at the time of the study.

4 60 South of compressor 77.56 87.60
5 30 Southwest of compressor 79.58 90.42
6 60 Southwest of compressor 75.10 86.06
7 30 West of compressor 80.65 94.23

11 120 West of compressor 67.31 83.90
12 240 West of compressor 60.11 78.94
Sound levels were measured at the monitoring locations using Brüel & Kjær Type 2250, 4th
generation, hand-held analyzers (S/N: 3003239) and (S/N: 3002528). Manufacturer’s
specifications for these meters are provided in Attachment 2. The software modules in the Type
2250 allows for real-time frequency analysis, analysis of time histories for broadband parameters
and spectra, and documentation of measurements through recording of measured sound.
These meters were chosen to measure and log sound levels for this survey because the equipment
is relatively versatile and rugged, measures sound levels over a wide range, allows user-defined
profile measurements to be used in lieu of factory preset profile measurements, allows for the
measurement of several sound parameters at discrete time intervals, and stores all of the
collected data for subsequent download and reduction on a computer.
Sound pressure level measurements are commonly weighted in relation to their frequency
components in order to provide a consistent basis for comparison to other measurements of the
same type. The following graph depicts three common weighting curves plotted together for
reference.
AXIP 7044 Compressor Noise Signature 140822 August 2014
An A-weighted filter was used during this study which corresponds to the human ear’s response
at low to medium sound levels. Time weighting defines how the exponential averaging in root-
mean-square measurement is done. The A-weighted filter with fast time weighting is common
for environmental noise measurement.
The following A-weighted sound level parameters were recorded every second of the study:
· LAeq - The equivalent continuous sound level over a specified period of time that
represents the same energy as the actual time varying noise signal;
The ‘A’ in the above variables denotes that the A-weighting has been included and the ‘F’
denotes that the fast time weighting was used.
In addition to the above measurements taken on the Apache Bay City Compressor Station,
spectral analysis was also conducted on this study. The sound from the Apache Bay City
Compressor Station was broken down into its frequency components using third-octave bands.
A third-octave band is defined as a frequency band whose upper band-edge frequency is 1.26
times the lower band frequency. As commonly used with octave band filters, C-weighting was
used in the spectral analysis. In Attachment 3, Figures 1 through 12 show the total spectrum
frequency plots for each of the monitoring locations.

It should be noted that dBs are a measure of sound energy based on a logarithmic scale. As such,
a sound level of 60 dB contains 10 times more sound energy relative to a sound level of 50 dB,
and a sound level of 70 dB contains 100 times more sound energy relative to a sound level of 50
dB.
Principle captured data from 12 monitoring locations during operations of the 7044 compressor.
It should be noted that the monitoring was conducted during a clear day with slight wind. All
wind speeds measured during monitoring did not exceed 8 mph.
After monitoring, the data collected by the meters was downloaded to a computer using Brüel &
Kjær BZ-5503 Utility Software for Hand-held Analyzers Version 3.11.0.335. Due to the
frequency at which the meters log information, the data generated by this study is voluminous.
To reduce this into meaningful information, Principle used the manufacturer’s software, coupled
with Excel spreadsheets, to summarize the data.
