The Environmental Protection Agency yesterday  unveiled a number of proposed oil-and-gas-development air-pollution rules that it says would be highly cost-effective for the industry.  The Daily Sentinel writes that supporters of the EPA say these rules are needed to reduce emissions such as ozone constituents and cancer-causing benzene.  The EPA says it is proposing the first federal air standards for wells that are developed through hydraulic fracturing.  The process would further protect the environment because  the EPA explains that methane is more than 20 times as potent as carbon dioxide as a greenhouse gas.
