EPA has studied the efficiency of chemical dispersing agents on spilled
oils, using a laboratory test called the baffled flask test. Experiments
were conducted at various temperatures, degrees of volatilization
and energy levels. The results are documented in Characteristics
of Spilled Oils, Fuels, and Petroleum Products: 2a. Dispersant Effectiveness
Data for a Suite of Environmental Conditions - the Effects of Temperature,
Volatilization, and Energy, U.S. Environmental Protection Agency, Athens,
GA. Publication No. EPA/600/R-04/119.

- Water Quality
Trading Assessment Handbook - EPA is releasing a document to help
water quality managers and watershed stakeholders determine if
trading can be used in their watershed to make cost-effective pollutant
reductions that achieve water quality standards. Using a hypothetical
river basin, the The Water Quality Trading Assessment Handbookillustrates
an analytical framework that can be used in any watershed to evaluate
the conditions and water quality problem(s) and determine if water
quality trading might effectively address local conditions. You
can order paper copies of the handbook free of charge through the
National Service Center for Environmental Publications at (800)490-9198
or via email at ncepimal@one.net You can find additional information
about water quality trading at www.epa.gov/owow/watershed/trading.htm For handbook questions you may contact Lynda Hall (202)566-1210 or Katharine
Dowell (202)564-1515 (Office of
Water).

Regional
Vulnerability Assessment for the Mid-Atlantic Region: Evaluation
of Integration Methods and Assessment Results - Prioritization
of risk management actions involves balancing many different factors
that can be addressed through a series of assessment questions.
Analysis results presented here should provide useful information
to others involved in integrated risk assessment in that integration
methods were tested and compared using the same set of regional
spatial data. By comparing the results of each method, we have
identified which integration methods are appropriate to address
different types of assessment questions that contribute to informing
decisions that require prioritization of areas for risk
management actions. These results are directly transferable to
other regions and can be applied to other scales of data. A 90
pp., 2.4 MB Adobe Acrobat (PDF)

Air
Quality Criteria for Particulate Matter (October 2004) - EPA has
completed the process of updating and revising, where appropriate,
its Air Quality Criteria for Particulate Matter (PM) as
issued in 1996 (usually referred to as the Criteria Document). Sections 108
and 109 of the Clean Air Act require that EPA carry
out a periodic review and revision, where appropriate, of the air quality criteria
(embodied in the Criteria Document) and national
ambient air quality standards (NAAQS) for criteria air pollutants such as PM.
The final version of the entire PM Criteria Document
was issued in October 2004 (National
Center for Environmental Assessment).

Standardized
Analytical Methods for Use During Homeland Security Events - EPA's Homeland Security
Research Center, in conjunction with EPA's Laboratory and Capability Committee,
has developed a list of Standardized
Analytical Methods (SAM) to be used by environmental laboratories in analyzing
biological and chemical samples associated
with threats to homeland security. SAM provides a standard by which to measure
specific types of contamination that may be
associated with future terrorist attacks. Ultimately, these procedures will be
vitally important in assisting state and local
government laboratories that are preparing to analyze samples associated with
homeland security events. A 90 pp., 580

2005 Fuel Economy Data -
Fuel economy information for 2005 cars, trucks, SUVs and vans is now available
to help consumers
make good environmental choices when purchasing new vehicles. This is the 30th
year that the

Rapid
Processing of Turner Designs Model 10-AU-005 Internally Logged Fluorescence
Data - EPA hydrologist, Malcolm Field, has developed a computer program,
FLOWTHRU, to facilitate the manipulation and processing of
fluorescence data downloaded from a Turner Designs Model 10-AU-005 fluorometer.
FLOWTHRU improves data collection by
rapidly dispensing with unwanted header data, recognizing and adjusting to
time-data breaks, and rewriting the data into decimal
time units for processing by modeling programs such as QTRACER2. Dr. Field
developed FLOWTHRU to cut down on time spent
editing data(sets) and thereby improving data quality (less error) and efficiency (National
Center for Environmental Assessment).

Particulate
Matter Research Program: Five Years of Progress -
Five years of research confirms the need to reduce fine particle air pollution.
EPA's proposed Clean Air Interstate Rule (CAIR) will result in the deepest
cuts in a decade in emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)
- the two most important precursors of fine particle pollution (Office
of Research and Development).
