Answer from Occidental:
We have developed a rigorous process for analyzing and mitigating surface impacts at each of our locations. For the pads near Erie, this includes a quiet completions fleet, sound walls, our water-on-demand system, continuous air quality monitoring, and paved access roads.
Per COGCC rules, baseline water quality samples were collected from nearby water wells prior to drilling the wells. Subsequent water samples will be collected after the completions activity is complete to ensure water quality in the area has not been affected. All water well sample results are provided to the COGCC and can be accessed on the COGCC website.
