Tompkins 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 noise 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 Tompkins UIC facility. Using the planned distances, conclusions can be drawn about the potential sound pressure levels that pump operations at the Tompkins 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 Tompkins 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 Tompkins 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 approximately 150 feet to the south of the pump house. Therefore Olsson has used 350 feet as the compliance point. Olsson has also calculated the sound pressure levels at 600 feet from the noise generating equipment to ensure that noise would not be a nuisance at the nearest occupied structure(s), located approximately 600 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 compliance point or the nearest occupied structure(s). 014-2878 Sound Data Review –Tompkins UIC Facility 12/31/14 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 also assessed the potential noise level at 600 feet using the noise/distance extrapolation equation provided in COGCC Rule 802 and calculated average sound pressure level. The calculated sound pressure level at 600 feet from the equipment will be approximately 39 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 Tompkins facility. Comparing the actual average sound pressure level from the Valley Farms F facility, it appears that the operation of a similar pump should be below the residential limit at 350 feet from the planned location and at the nearest occupied structure. 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. Statement of Qualification I am a multi-disciplinary Project Manager at Olsson Associates. I have coordinated many Noise Control Regulation Compliance Assessments over 5 years at existing and planned noise generating equipment installations in Colorado.
