Dive Summary:

• Southwestern Electric Power Co., a unit of AEP, and Arkansas Electric Co-Op Corp. have asked the Arkansas Public Service Commission to review plans for the installation of emissions controls at the Flint Creek coal-fired power plant in Arkansas.
• If the review doesn't lead to an approval, the plant could be closed by 2015; the estimated capital cost of the retrofit is $408 million and would be split between the co-owners.
• The co-owners are attempting to complete the installation by April of 2015 to comply with new Environmental Protection Agency requirements.

The companies plan to install a dry flue gas desulfurization system, or a scrubber; a fabric filter, or a baghouse; an activated carbon injection and low NOx burners and overfire air system to control sulfur dioxide, nitrogen oxides, mercury and other emissions. ...
