Dive Summary:

• The owner of some of the largest sources of carbon-dioxide emissions in the U.S., American Electric Power Co., argued today that proposed EPA rules requiring coal-fired power plants to have expensive carbon-capture and storage technology are impractical and rely on as-of-yet unviable technology.
• AEP tested the proposed technology at a West Virginia plant from 2009 until it shut the project down last year, and currently supports legislation being pushed by Republican lawmakers to curb EPA regulations.
• Democrats and environmental groups say the regulation is necessary to prod along the development of the technology and combat global warming.
