HGS Air Permit Formally Remanded 5/30/2008:

UPDATE 5/30/08: The Board of Environmental Review voted unanimously today to remand the Highwood Generating Station air pollution permit back to the DEQ to do a complete BACT analysis on PM2.5. The Board was very clear that they believe it is possible to conduct the proper analysis to determine whether in fact the facility will be using the best control technology available today to control fine particulates. This is a tremendous victory for public health..........

WHEREFORE, IT IS HEREBY ORDERED
, that Permit No. 3423-00 is remanded for a thorough top-down BACT analysis of PM2.5. If a PM2.5 filterable, BACT analysis cannot be performed, a thorough top-down BACT analysis of PM10 shall be conducted. In either case, a top-down BACT analysis conforming to the NSR Manual will be deemed to be sufficiently thorough. Read full story
