Denver (AP) - Colorado Democratic Congresswoman Diana DeGette plans to reintroduce a bill that would regulate a widely used oil and gas drilling process under federal environmental laws.
The bill would repeal a provision in a 2005 energy bill that prevents regulation of hydraulic fracturing under the federal Safe Drinking Water Act. The exemption was approved after a federal
report said there was little or no threat to underground drinking water from the practice.
Critics say that report was flawed. They blame the process, known as ``fracking,'' for health and environmental problems in oil and gas fields in the Rockies and other regions.
Fracking involves injecting liquids, sand and chemicals underground to force open channels in tight sand and rock formations so the oil and gas will flow.
