Colorado Proposition 112, a measure that would have altered the required distance for new wells to be at least 2,500 feet from occupied buildings and other “vulnerable areas.”

Colorado Proposition 112, a 2018 ballot measure, proposed increasing the minimum distance for new oil and gas development to at least 2,500 feet from occupied buildings and other vulnerable areas such as schools and water sources. The measure aimed to enhance public health and safety by reducing exposure to potential hazards from oil and gas operations. However, it faced significant opposition from the oil and gas industry, which argued that the increased setback would severely limit drilling opportunities and negatively impact the state's economy. According to a report by the Common Sense Policy Roundtable, the measure could have resulted in up to 147,800 job losses and $1.1 billion in forfeited tax revenue by 2030, with more than four out of every five non-federal acres in Colorado becoming off-limits to new drilling. Proponents of Proposition 112, such as Colorado Rising, argued that the economic impact claims were exaggerated and emphasized the health risks associated with the current 500-foot setback. Ultimately, Proposition 112 was rejected by Colorado voters in the 2018 election. For more detailed information, you can refer to the Colorado Legislative Council Staff and Ballotpedia.
