| Noise mitigation | Form: (02A )
403656949
9/12/2024 | Oxy conducted a Noise Impact Assessment (NIA) for each phase of operations (drilling and production) to assess operational noise levels against the maximum permissible dBA and dBC noise levels stated in both the Colorado ECMC Rule 423 and the WOGLA Section 215-435 noise regulations. Each phase of operation will comply with the MPNLs of both codes as summarized in Table 4 in Section 2 of this document.
Oxy is utilizing a modified drilling rig designed to reduce overall noise levels. This will include low noise level shale shakers and modifications to the generator house to reduce noise levels from the exhaust vents and radiator fans. Additional noise reduction modifications may also be implemented depending on the rig contractor utilized following a noise survey study.
Prior to commencement of drilling activities, a partial perimeter, engineered sound wall consisting of approximately 760 linear feet of 32-foot-tall, STC32 wall will be installed around the edge of the well pad to reduce noise levels at the critical receptor points.
A baseline ambient sound level survey was not conducted at the time of the writing of this NMP. A survey will be conducted 30 and 90 days prior to the commencement of construction activities.
Throughout the duration of preproduction operations and any construction lasting longer than 24 hours, Oxy will conduct continuous noise monitoring at the ECMC ambient monitoring points (Monitoring Points 1 and 2) as seen in Figure 3 of Section 7.
If the drilling rig is changed prior to commencement of operations, the mitigation measures employed will be equally or more protective. A sundry form will be submitted to outline any changes, per both codes, as required.
Oxy will post contact information to receive and address noise complaints arising from preproduction operations around the clock, 24 hours, 7 days per week. Upon receipt of a complaint, either directly to Oxy, from the Colorado ECMC, or from Weld County, an Oxy representative will contact the associated stakeholder within 48 hours of receipt. |
