Foreword
NETL Hosts Successful By-Products Workshop
On March 19^th, NETL hosted a workshop, "Hg Control - The Effects on By-Products: What Do We Know and Where Do We Go?" The workshop, which was by invitation only, was well-attended by EPA and other regulatory agencies, as well as, personnel from 15 different utility companies. EPA has expressed concern that the by-products resulting from Hg controls may release Hg to the environment either via leaching or volatilization. EPA doesn't want Hg removed from utility flue gas ending up back in the global Hg pool. The primary objective of the workshop was to assess the Hg stability in by-products generated from Hg control tests conducted over the last year. Additional presentations included on-going laboratory tests examining by-products that have been spiked with high levels of Hg to mimic Hg control. EPA made a presentation discussing testing methods and issues of concern. Two panel discussions followed the presentations where other interested parties presented their perspective including: American Coal Ash Association (ACAA), Utilities Solid Waste Activities Group (USWAG), an ash marketing company, ISG Resources and a utility, TVA.
