11/24/2015 | 604.c.(2)A. Extraction intends on powering the drilling rig off of highline power, which would eliminate the noise caused by the generators on the rig. This noise mitigation solution requires proper infrastructure supplied by Xcel Energy. Extraction is currently working with Xcel Energy to have this infrastructure in place prior to the start of drilling. It is anticipated that this infrastructure will be ready for use by October 2015. Additionally sound walls will be constructed around this location to aid in the reduction of noise levels. |
