4-203.G.7 – Sound Data Review
Ursa Operating Co.
Speakman A UIC
At the request of Ursa Operating Co. (Ursa), Olsson Associates (Olsson) has conducted an
assessment of noise survey data. This noise survey data was collected at the Valley Farms F
injection operation. The sound generating equipment assessed was an electric triplex pump
used to inject waste water underground. The intent of this assessment was to review the data
to determine the sound pressure levels generated during the operation of the injection pump
and extrapolate that data out for comparison at the proposed Speakman A UIC facility. Using
the planned distances, conclusions can be drawn about the potential sound pressure levels that
pump operations at the Speakman facility will be in order to determine compliance with the
noise limits set forth in the Colorado Oil and Gas Conservation Commission (COGCC) Rule
802.
Noise Data
The data was collected by Ursa at the Valley Farms F UIC facility during the operation of the
noise generating equipment. The noise generated by this equipment should be comparable to
that equipment planned at the Speakman A facility. The noise measurements were collected on
April 8, 2014 approximately 350 feet south of the pump enclosure. An Extech Model 407764
Sound Level Meter was used to collect 518 consecutive noise readings at 15-second intervals.
Portions of the collected data were not useable because of external interference observed
during data collection. Such interference was related to adjacent vehicle traffic, onsite activities,
air traffic, and rural farming and ranching operations. Based on the observations of these noise
impacts, data collected during times of interference was excluded from the determination of the
average sound pressure level of the pump’s operation. The raw data is attached to this report.
Noise Generating Equipment
The electric triplex pump used at the Valley Farms F injection operation is identical to the pump
that is planned for installation at the Speakman A injection facility. The existing pump is located
inside a fabricated metal enclosure.
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 is 486 feet to the west of the facility. Therefore Olsson has used 486 feet away from
the noise generating equipment as the compliance point.
Olsson has also calculated the sound pressure levels at 1,162 feet from the noise generating
equipment to ensure that noise would not be a nuisance at the nearest occupied structure(s),
located at 1,162 feet to the west.
Maximum Permissible Noise Levels
Garfield County is applying the Residential/Agricultural/Rural noise standard, as prescribed in
COGCC Rule 802.The night time maximum permissible noise limit is 50 dB(A) for residential
areas. This noise pressure limit has been used to ensure that the proposed noise generating
equipment would not be a nuisance at the property line or nearest occupied structure(s).
Calculated Sound Pressure Levels
The average sound pressure level of the pump calculated from the noise survey data is 44
dB(A) at 350 feet. Olsson has assessed the potential noise level at 486 feet using the
noise/distance extrapolation equation provided in COGCC Rule 802 and the
generator/enclosure rating. The calculated sound pressure level at 486 feet from the equipment
will be approximately 41 dB(A).
Olsson has also assessed the potential noise level at 1,162 feet using the noise/distance
extrapolation equation. The calculated sound pressure level at 1,162 feet from the equipment
will be approximately 34 dB(A).
Conclusion
By utilizing the sound readings collected from an injection pump currently operating we can
estimate the sound pressure levels that would be generated from similar equipment operated at
the Speakman A facility. Extrapolating the actual average sound pressure level from the Valley
Farms F facility using the distances to the compliance points at the Speakman A facility it
appears that the operation of a similar pump should be below the residential limit at 486 feet

These sound pressure levels are calculated based on collected data from a similar operation
and actual noise levels should be measured during equipment operation to insure regulatory
compliance.
