The U.S. EPA regulatory requirements for mercury (Hg) monitoring effectively went into limbo after the Washington D. C. District Court of Appeals vacated the Clean Air Mercury Rule on February 8, 2008. This ruling was mandated on March 14, 2008, but the mandate was subsequently appealed on March 24, 2008. The outcome of this appeal is still pending.
If the ruling to vacate the CAMR stands, the federal requirements for continuous mercury monitoring under 40 CFR Part 75 may disappear. However, most experts agree that control of mercury emissions from coal-fired power plants will remain a high priority both nationally and world-wide. Any plan to curb power plant Hg emissions will require the accurate monitoring of the Hg content in combustion flue gas streams.
Although future monitoring requirements may change slightly from those currently specified, the overall technological requirements and challenges of mercury monitoring remain essentially the same. Appendix K sorbent trap monitoring remains a viable option for facilities that are required to monitor mercury emissions, regardless of the underlying regulatory driver. CleanAir's MET-80 system, with its design based on maximum versatility over a wide range of installation requirements, will continue to lead this charge.
