The EPA last year issued the first-ever standards to control smog- and soot-forming gases from gas wells site, and updated existing rules to reduce cancer-causing pollution, such as benzene, from other equipment.
The agency, in response to the report, agreed to develop a comprehensive strategy to improve its pollution figures.
An industry association, America's Natural Gas Alliance, had not seen the report and had no comment late Thursday.
