House Bill 1297, sponsored by Rep. Joann Ginal, D-Fort Collins, and Sen. Irene Aguilar, D-Denver, would examine data from Adams, Boulder, Larimer and Weld counties. The study would cost nearly $570,000 through fiscal 2017.
The final report would be due Jan. 1, 2017, and would be submitted for review for publication in a scientific journal.
Activists from Weld Air and Water in Greeley said they would testify in favor of the bill at the Capitol in Denver Thursday afternoon. The activists plan to share their concerns about oil and gas activity in urban areas such as Greeley.
Lawmakers on the House Health, Insurance and Environment Committee are expected to vote on the bill following testimony, a Ginal aide said. If the bill passes the health and insurance committee, it will head to the House Appropriations Committee.
The bill comes as oil and gas development booms in Northern Colorado. The activity has stirred controversy throughout the Front Range, with Fort Collins, Lafayette, Boulder, Broomfield and Longmont adopting restrictions on oil and gas extraction.
A coalition of activist groups also recently submitted language to the Colorado Legislative Council for a constitutional amendment to give local governments authority to regulate oil and natural-gas development.
