Erin Martinez was at a news conference in February when Colorado legislative leaders and Gov. Jared Polis announced a bill that would make sweeping changes to how oil and gas are regulated. And she and her family had a front-row seat as Polis signed the bill into law Tuesday. Martinez was one of the strongest supporters of Senate Bill 19-181, which changes the mission of the Colorado Oil and Gas Conservation Commission, the main regulatory body for the industry.
