The purpose of this review was to determine that the activities conducted at this location were in compliance with the noise limits set forth in the Colorado Oil and Gas Conservation Commission (COGCC) Rule 802 and Section 25-12-103 of the Colorado Revised Statutes (CRS). Additionally, the data was used to draw a correlation to expected sound pressure levels at the proposed BMC B and BMC D Production Pad facilities (proposed facilities). Location The Monument Ridge Production Pad facility (the location) is a natural gas production pad. During the data collection period, several gas wells were drilled, completed, and produced. Drilling and completion operations consisted of many different processes including conductor pipe setting, surface drilling, production drilling, hydraulic fracturing, flowback and several other operations. A noise mitigation sound wall was installed around the facility during the data collection period. Sound Data The sound data reviewed was collected and reported by Behrens and Associates Inc. (Behrens). The data was provided to Olsson for this review. The data was collected using two meters stationed adjacent to the location. One meter was installed 350 feet east and one installed 350 feet west of the center of the location. For meter installation location and sound level data, see the attached reports. Compliance Point 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. Due to the nature of sound pressure, levels decrease over distance. Therefore using 350 feet as a compliance point is appropriate for this review. 760 Horizon Drive, Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com 014-1829 Review of Sound Data — URSA Drilling, Workover and Installation 10/16/14 Maximum Permissible Noise Levels During the data collection period, numerous gas wells were drilled and completed. Production equipment was installed during the data collection period as well. As prescribed in COGCC Rule 802, "operations involving pipeline or gas facility installation or maintenance, the use of a drilling rig, completion rig, workover rig, or stimulation is subject to the maximum permissible noise levels for industrial zones". The maximum permissible noise levels for Industrial zones are 80 dB(A) during daytime operations (7AM to 7PM) and 75 dB(A) during night time operations (7PM to 7AM). Reported Sound Pressure Levels All sound pressure levels reported in the attached reports indicate that all sound pressure levels, measured during the data collection period, are either within the maximum permissible noise levels or were not applicable due to wind generated overages. Conclusion The data presented for this review indicate that Ursa's drilling, completions and installation operations at the location are within the maximum permissible noise levels set by the COGCC. As it is understood by Olsson, future drilling, completion and installation operations at the proposed facilities will utilize the same equipment and operations as those used for the Monument Ridge Production Pad facility. Therefore it is a valid assumption to assume that sound generated from those operations will produce similar sound pressure levels during future operations at the proposed facilities. Due to differences in topography and local surfaces, this review does not assure regulatory noise compliance with operations at the proposed facilities and sound pressure monitoring should be conducted if there is a concern, complaint or a major change in operations that could affect sound pressure levels. 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.
