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.

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.
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.
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.

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.

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).

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 (June 2014, 69 pages).

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).
