"NEW YORK - Green groups sued the U.S. Environmental Protection Agency on Thursday to force Texas to toughen its stance on air pollution by using stricter language in permits it issues to oil refineries and power plants.

Five separate lawsuits have asked a federal court in Washington to force EPA Administrator Scott Pruitt to respond to petitions by the groups, including the Environmental Integrity Project and the Sierra Club. They want the EPA to intervene in permits issued to several companies by Texas's environmental regulator, the Texas Commission on Environmental Quality (TCEQ).

The groups are claiming each permit is too weak and does not force the companies to do enough to protect air quality."
