To prevent the Environmental Protection Agency from exceeding its statutory authority in ways that were not contemplated by the Congress.

Stopping EPA Overreach Act of 2017 This bill amends the Clean Air Act to exclude carbon dioxide, water vapor, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride pollution from the scope of that Act. The bill declares that current law does not authorize or require the regulation of climate change or global warming and nullifies certain final rules relating to: (1) greenhouse gas and volatile organic compounds emissions, including methane emissions, from the oil and natural gas sector; and (2) carbon pollution emissions from the utility power sector. Before proposing or finalizing regulations or policies, the Environmental Protection Agency must analyze the net and gross impact of those regulations and policies on employment. Regulations and policies may not take effect if they have a negative impact on employment, unless they are approved by Congress and signed by the President.
