Fall 2012 EPA Science To Achieve Results (STAR) Fellowships For Graduate Environmental Study. The U.S. EPA, as part of its STAR program, is offering Graduate
Fellowships for master's and doctoral level students in environmental fields of study. Subject to availability of funding and other applicable considerations,
the Agency plans to award approximately 80 new fellowships by July 31, 2012. Master's level students may receive support for a maximum of two years. Doctoral
students may be supported for a maximum of three years, usable over a period of five years. The fellowship program provides up to $42,000 per year of support per
fellowship. The application deadline is November 8, 2011. More information, eligibility criteria, and application instructions are available at http://epa.gov/ncer/rfa/2012/2012_star_g ...
FY 2012 EPA Brownfields Assessment, Revolving Loan Fund and Cleanup Grant Guidelines - Request for Proposals. These grants may be used to address sites contaminated
by petroleum and hazardous substances, pollutants, or contaminants (including hazardous substances co-mingled with petroleum). Opportunities for funding
are as follows: Brownfields Assessment Grants (each funded up to $200,000 over three years; coalitions are funded up to $1,000,000 over three years), Brownfields
Revolving Loan Fund (RLF) Grants (each funded up to $1,000,000 over five years) and Brownfields Cleanup Grants (each funded up to $200,000 over three years).
The proposal deadline is November 28, 2011. Proposal guidelines are available at http://www.epa.gov/brownfields/applicat. ... .
EPA's Apps for the Environment Challenge Update! Now is the time to vote for your favorite app! Previous posts on TechDirect described EPA's exciting Apps
for the Environment Challenge effort (http://www.epa.gov/appsfortheenvironmen ... The deadline for apps submissions for this competition was September
16. We are very excited to report that we received 38 apps and we're so impressed with their creativity and diversity! Now it's time for you to vote - help your favorite
app win the People's Choice Award! Vote here: http://appsfortheenvironment.challenge.g ... Voting closes on Friday, October 7. Send a message
to the developers that you like their work and spread the word! At that same link, you can have fun taking the apps out for a test drive and see which ones you want
to use to protect or understand the environment. Some apps are games, others are available on the Web, and a few are ready to download to your smartphone. The topics
range from local air quality to fish in rivers to power plants. Don't forget to keep an eye on our EPA Data and Developer Forum so you get the latest news about the
challenge and tell us what you think should come next. You can also follow the dialogue on Twitter using the #GreenApps hashtag!
> Upcoming Live Internet Seminars
Nanotechnology: Implications and Applications - October 3, 2011, 1:00PM-3:00PM EDT (17:00-19:00 GMT). Nanotechnology encompasses a diverse range of
materials with a variety of applications, including those relevant to Superfund sites. As with any new technology, concerns have been raised about the potential
for human toxicity and environmental impact of nanoparticles. In this two-part seminar, investigators from the National Institute of Environmental Health
Sciences Superfund Research program (SRP) will explore the implications of nanoparticles on human health, as well as applications of nanotechnology-based
environmental sensing. Remediation of Superfund sites can release nanoscale particles into the environment, which can pose exposure risks. The health effects
of these complex mixtures and materials, especially emerging materials produced by the nanotechnology industry, are not sufficiently well understood.
Dr. Ian Kennedy, of the University of California-Davis SRP, will discuss the potential for adverse environmental effects and human health effects that can
arise from exposure to both intentionally manufactured and unintentionally produced nanomaterials. The primary focus will be on metals and metal oxide nanomaterials.
There remains a compelling need for improved ways to detect and quantify toxic and/or hazardous chemical species found at existing or potential Superfund
sites. Better analytical techniques could reduce the cost of monitoring, help improve remediation methods, and more accurately assess the health risks associated
with hazardous and toxic species. Nanoscale materials provide an opportunity to develop new methods that could be faster, easier, smaller, and/or less expensive.
Dr. Donald Lucas, of the Lawrence Berkeley National Laboratory, and a member of the University of California-Berkeley SRP, will discuss how changing the size
of materials to the nanoscale changes their properties. These changes can be exploited to produce sensors and detectors that have the potential to reduce the
cost and improve detection limits. Examples include the use of controlled shape silver and gold nanoparticles to detect arsenic and mercury in air and water.

NARPM Presents...Software Demonstration of the ATSDR Brownfields/Land Reuse Site Tool and the ATSDR Dose Calculator Tool - October 4, 2011, 1:00PM-3:00PM
EDT (17:00-19:00 GMT). The ATSDR Brownfields/Land Reuse Site Tool is a rapid site screening and multiple chemical exposure dose-calculating tool that allows
users to assess sites by past/future use, institutional controls, sensitive populations, and suspected or confirmed contamination. The Dose Calculator
tool allows users to compute the amount of a toxic substance an individual may be exposed to (dose). Both tools are widely used by health and regulatory agencies,
Tribal governments, planners, and environmental health professionals. For more information and to register, see http://clu-in.org/live .
Innovative Approaches to Mining Site Remediation and Reuse Workshop - October 6, 2011, 8:30AM-10:30AM EDT (12:30-14:30 GMT). The opening plenary session
for the Innovative Approaches to Mining Site Remediation and Reuse Workshop will be broadcast live via CLU-IN. Join us to hear opening remarks from Mr. Barnes
Johnson, Deputy Director, EPA Office of Superfund Remediation and Technology Innovation, followed by presentation
