The Ohio Environmental Protection Agency on March 28 issued a draft air permit-to-install that would allow some changes by American Electric Power (NYSE: AEP) for its Reduced Emissions Fuel coal system at the General James M Gavin power plant.
The company is proposing to modify the material handling equipment by adding a Reduced Emissions Fuel (REF) handling system to the current coal handling system. REF is coal with chemical additives that reduce certain emissions, particularly mercury, when the coal is combusted. Gavin is a two-unit, 2,640 MW (net maximum) plant located in Cheshire, Ohio.
“The proposed new design for the REF material handling operation consists of four material conveyors, three process enclosures, a non-regulated liquid material storage tank and a dry material storage silo,” said the draft permit. “The resulting potential emissions from this change are slightly less than those recently permitted under PTI No. P0108666 when limiting the throughput to 13,000,000 tons per year. Therefore, to ensure that the redesigned process does not increase emissions above those permitted under PTI No. P0108666, a production limit of 13,000,000 tons of coal per year is proposed for the REF material handling system.”
Changes to the REF material handling system include consolidating from two processing lines into a single processing line which includes a new crushing building in addition to the new pugmill.
