FY 2015 Brownfields Area-Wide Planning (BF AWP) Grant Guidelines. EPA is announcing the
availability of funding to eligible entities who wish to develop an area-wide plan for brownfields
assessment, cleanup, and subsequent reuse. This funding is for research, technical assistance, and/or
training activities directed to one or more brownfield site(s) located in a specific area (such as a
neighborhood, district, local commercial corridor, community waterfront or city block). Each project
funded under this grant must result in an area-wide plan which includes specific plan implementation
strategies for assessing, cleaning up, and reusing the brownfields site(s) as well as related brownfields
and project area revitalization strategies. EPA anticipates awarding approximately 20 projects in total,
funded at up to $200,000 each. Please note that applicants who received a BF AWP grant from EPA
in Fiscal Year 2010 or 2013 (FY10 or FY13) are not eligible to apply under this competition. The
proposal submission deadline is September 22, 2014. For more information and grant guidelines, see

If Cells Could Talk, What Would They Tell Us About Environmental Exposures? Applications of
Cell-Based Bioanalytical Methods - August 11, 2014,1:00PM-3:00PM EDT (17:00-19:00 GMT).

This two-part seminar will feature Dr. Michael Denison of the University of California Davis Superfund
Research Program (SRP) and Dr. Scott Boitano from the University of Arizona SRP, and will focus on
applications of cell-based bioanalytical methods to better understand environmental toxicities. The
ability of toxic chemicals, such as dioxin-like chemicals and endocrine disruptors, to modulate
intracellular receptor-mediated signal transduction is one way that diverse toxicants can produce
common responses. In the laboratory, these cellular mechanisms can be taken advantage of and
used to develop screening methods to better detect and quantitate such chemicals in a variety of
sources to which people may be exposed. Dr. Denison will describe the development, validation, and
screening applications of Chemically-Activated LUciferase expression (CALUX) cell bioassays.
Diseases associated with the airway often contain living cells with compromised cellular physiology.
Thus, traditional cellular toxicity assays that measure cell death as a single toxicity endpoint may miss
the more subtle sub-cytotoxic changes seen in airway epithelial cells. To better evaluate both cytotoxic
and sub-cytotoxic changes, researchers have adapted a human airway epithelial cell line for use in the
xCELLigence real time cell analyzer to evaluate concentration- and time-dependent effects of toxic
compounds. Dr. Boitano will discuss these findings and how they allow us to better understand the
toxicity impact of nanoparticles, metals and metalloids, as well as other toxicants, on airway health and
disease. For more information and to register, see http://ciu-in.ora/iive .

Military Munitions Support Services - Explosives Safety - August 21, 2014,1:00PM-4:45PM EDT

Services (M2S2) community. During this session, speakers will provide updates on explosives safety
policy, processes, best practices, and incident review. For more information and to register, see

ITRC Groundwater Statistics for Environmental Project Managers - August 26, 2014,
2:00PM-4:15PM EDT (18:00-20:15 GMT). Statistical techniques may be used throughout the process
of cleaning up contaminated groundwater. It is challenging for practitioners, who are not experts in
statistics, to interpret, and use statistical techniques. ITRC developed the Technical and Regulatory
Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) and this
associated training specifically for environmental project managers who review or use statistical
calculations for reports, who make recommendations or decisions based on statistics, or who need to
demonstrate compliance for groundwater projects. The training class will encourage and support
project managers and others who are not statisticians to: use the ITRC Technical and Regulatory
Web-based Guidance on Groundwater Statistics and Monitoring Compliance (GSMC-1, 2013) to make
better decisions for projects; apply key aspects of the statistical approach to groundwater data; and
answer common questions on background, compliance, trend analysis, and monitoring optimization.
ITRC's Technical and Regulatory Web-based Guidance on Groundwater Statistics and Monitoring
Compliance (GSMC-1, 2013) and this associated training bring clarity to the planning, implementation,
and communication of groundwater statistical methods and should lead to greater confidence and
transparency in the use of groundwater statistics for site management. For more information and to

Engineering Paper: In Situ Thermal Treatment Technologies: Lessons Learned. The purpose of
this paper is to convey useful information gained from approximately 10 years of development and
deployment of in situ thermal treatment (ISTT) technologies. This paper is the result of a series of
in-depth interviews with U.S. EPA Remedial Project Managers (RPMs) and On-Scene Coordinators
(OSCs) and with ISTT vendors whose experience extends beyond federal response action sites to
include state-regulated cleanups and Brownfields/voluntary cleanups, as well as international projects.
While the focus is on federally-funded cleanup sites, many of the lessons learned will be of interest to
RPMs and OSCs who are overseeing potentially-responsible party (PRP)-lead cleanups (May 2014,
46 pages). View or download at http://ciu-in.ora/techpubs.htm .

Evaluating Potential Exposures to Ecological Receptors Due to Transport of Hydrophobic
Organic Contaminants in Subsurface Systems (EPA 600-R-10-015). This technical paper
recommends several types of screening assessments to evaluate site conditions for the potential to
enhance transport of Hydrophobic Organic Contaminants (HOCs), as well as site artifacts that result
from inadequate well installation and sampling procedures within a ground-water monitoring network.
These assessments are incorporated into a suggested three-tiered decision analysis process that
attempts to address all potential mechanisms that can result in HOC transport to surface water. For
sites in which a complete exposure pathway exists from ground water to surface water, the paper
summarizes a process for using HOC exposure information to estimate risks to ecological receptors

Radiation Risk Assessment At CERCLA Sites: Q & A (OSWER Directive 9200.4-40). This fact
sheet provides an overview of current EPA guidance for risk assessment and related topics for
radioactively contaminated CERCLA sites. It provides answers to several commonly asked questions
regarding risk assessments at radioactively contaminated CERCLA sites. Also, it provides further
guidance that dose assessments should only be conducted under CERCLA where necessary to
demonstrate ARAR compliance, and that dose-based ARARs should be 12 mrem/yr or less to be
considered protective. In addition it also provides guidance on how to comply with indoor radon
standards. This fact sheet supersedes an earlier Q&A from December 1999 (May 2014, 47 pages).

Developing a Program for Contaminated Site Management in Low and Middle Income
Countries. The objective of this document is to summarize the rationale and the major policy,
legislation, regulatory, implementation, and organizational issues involved in creating a contaminated
site program, especially for low and middle income countries. It offers alternatives regarding the
design and implementation of such a program. It proposes an action agenda of short- and longer-term
actions to be considered in forming a contaminated site program, including creation of a national
management plan for contaminated sites. In addition to providing some optional approaches for the
many policy and programmatic issues, the document provides numerous references from the
experience of other country programs for international financial institutions and assistance agencies
and country ministry leaders, staff and concerned stakeholders to draw upon in considering program
options. This guide recommends developing a national management plan for contaminated sites that
addresses goals and objectives for the program, outlines operational procedures, and calls for regular
reporting on results and environmental outcomes (May 2014, 65 pages). View or download at
