In 2018, oil and gas companies reported nearly 3,000 drilling-related spills in the Mountain West’s three top producing states. Colorado and New Mexico make spill information public and Wyoming provided the information by request. The Center for Western Priorities obtained 2018 data from each of these states and quantified what materials were spilled and which operators were responsible in order to better inform the public on drilling impacts.
