mercury emissions control, following the release of ‘Study of Hazardous Air Pollutant Emissions from Electric Utility Steam
Generating Plants - Final Report to Congress,’ in February 1998. The first three chapters describe EPA’s December 2000
decision to regulate mercury under the National Emission Standards for Hazardous Air Pollutants (NESHAP) provisions of
the Clean Air Act, coal use in electric power generation, and mercury behavior in coal combustion. Chapters 4-9 report: new
information on current electric utility fuels, boilers, and emission control technologies; mercury emissions associated with
these diverse technology combinations; results and implications of tests to evaluate the performance of mercury control
technologies and strategies; retrofit control cost modeling; and mercury behavior in solid residues from coal combustion. The
final chapter summarizes current research and identifies future efforts needed to ensure cost-effective control of mercury
emissions. References are provided at the conclusion of each chapter.

The Selected Office of Water Methods and Guidance CD-ROM includes recently developed and frequently requested
analytical methods and related guidance, including methods for the detection of trace metals, microbiological contaminants,
and organics in wastewater and drinking water, chemical and biological methods for biosolids, guidance documents on Office
of Water’s (OW) revised approach to method approval, whole affluent toxicity testing, and oil and grease analysis. Version 2.0
of this popular CD-ROM lets you search, print and display the full text of more than 500 EPA wastewater and drinking water
methods and guidance documents. Additionally, the CD-ROM contains the full text of all EPA methods approved for
compliance monitoring at 40 Code of Federal Regulations (CFR) part 136 and 141 including the 500-, 600- and 1600-series
methods and a complete version of the March 1983 revision of Methods for Chemical Analysis of Water and Waste
(MCAWW). For the first time, the Office of Water CD-ROM identifies which methods are approved at 40 CFR parts 136 and
141 for wastewater and drinking water compliance monitoring. The EPA Methods and Guidance for the Analysis of Water
CD-Rom, version 2.0, includes the full text of newly developed EPA wastewater and drinking water methods and guidance
documents. Additionally, the CD contains tables detailing what methods are approved at 40 CFR part 136 and 141. For the
first time, the Office of Water CD includes links tables based on those in the Code of Federal Regulations (CFR) listing which
methods are approved for wastewater and drinking water compliance monitoring. Accessing approved EPA water test methods
has never been easier. To find which methods are approved an an analyte of interest, simply click on the tables of approved
methods button and search by analyte. Then click on the EPA method number listed for that analyte to instantly access the
full text of approved methods listed at 40 CFR parts 136 and 141. Software includes a powerful text search engine to allow
searches by method number, analyte name, and key words. All methods, guidance documents, and graphics have been
converted to Adobe Acrobat8 Portable Document Format (PDF) to ensure efficient text searches.

By combining complementary monitoring observations spanning long, medium and short time scales, we have
constructed power spectral densities (PSDs) of six Seyfert 1 galaxies. These PSDs span approx. greater than 4 orders of
magnitude in temporal frequency, sampling variations on time scales ranging from tens of minutes to over a year. In at least
four cases, the PSD shows a ‘break,’ a significant departure from a power law, typically on time scales of order a few days.
