Internet Seminars  
ITRC Design, Installation and Monitoring of Alternative Final  
Landfill Covers - November 3.  This training focuses on  
evapotranspiration (ET) covers and the decisions associated with  
their successful design, construction, and long-term care.  For more  
information and to register, see or .  
ITRC Radiation Site Cleanup: CERCLA Requirements and  
Guidance - November 8.  The focus of this ITRC training is  
EPA's guidance for remediating radioactively contaminated sites,  
which can facilitate cleanups that are consistent with how chemical  
contaminants are addressed, except where technical differences  
posed by radiation are addressed. This course also discusses long  
term stewardship (LTS) challenges related to the large radioactively  
contaminated sites. This understanding of LTS issues is integral to  
the cleanup process and decisions made at the radiation sites.  To  
register, see or .  
ITRC Triad Approach: A New Paradigm for Environmental Project  
Management - November 10.  This seminar discusses the  
relationship of the Triad to previous regulatory guidance, and  
offers a discussion of issues that may affect stakeholders.  The  
ITRC guidance document, Technical and Regulatory Guidance for  
the Triad Approach: A New Paradigm for Environmental Project  
Management (SCM-1, 2003), serves as the basis for this training  
course. To register, see or .  
Socio-Economic Causes and Consequences of Future  
Environmental Changes - November 16.  EPA's National Center  
for Environmental Economics (NCEE), and Region 9 are  
sponsoring a workshop on future environmental scenarios research  
supported by NCER. Topics include trends in housing and how  
they affect land-use and land-cover changes, economic and  
demographic drivers of aquaculture, and the economics of  
estimated increases in greenhouse gas emissions.  Additional  
research on the consequences of global change, including climate  
and climate variability, land use, economic development, and  
technology on air quality will also be presented.  Land use  
planners, air quality and water quality agency staff, transportation  
specialists, conservation managers, aquaculture experts, and those  
interested in energy use and management will learn about EPA's  
latest research in this area.  To register, see .  
ITRC Constructed Treatment Wetlands - November 17.  This  
course, developed by the Interstate Technology and Regulatory  
Council (ITRC), is based on Technical and Regulatory Guidance  
for Treating Storm Water and Wastewater Using Constructed  
Treatment Wetlands (WTLND-1).  It describes the physical,  
chemical, and biological mechanisms operating in wetlands  
treatment systems, the contaminants to which they apply, the  
characteristics of sites suitable to treatment in this fashion, and  
relevant regulatory issues.  To register, see

Jump-Starting Ecological Restoration - Soil Health - December 1.  
Any restoration effort is only as good as the soil that it is built  
on.  The goal of this Internet Seminar is to provide site managers  
with the basics of soil science and with available tools to build a  
beautiful soil in a single season.  By taking this Internet Seminar,  
participants will gain the tools necessary to evaluate the conditions  
of the soils at their sites, identify locally available and cost-  
effective residuals that would effectively improve these soils, and  
gain familiarity with a number of different application options for  
incorporating these amendments into site soils.  The potential for  
amendments to be used for in situ remediation will be clear  
through the case studies.  As managers are being faced with both  
reduced resources and the need to consider end uses of sites, this  
type of approach is an essential first step towards ecological  
restoration.  To register, see .  
Improving Contracting, Design, and Evaluation of  
Groundwater Pump and Treat Systems -  December 5.  This  
seminar discusses four recent EPA fact sheets on lessons learned  
from conducting optimization reviews at over 30 pump and treat  
(P&T) systems nationwide. The seminar covers the cost-effective  
design of P&T systems as well as effective management,  
contracting, and reporting for operating P&T systems.  Illustrative  
examples convey a number of concepts, including design  
considerations at complex sites, describe the primary components  
of a capture zone evaluation, and discuss the merits of fixed-price  
or time-and-materials contracts for long-term operations and  
maintenance (O&M) of P&T systems.  One of the fact four sheets  
is a template for an O&M report, and the internet seminar presents  
the various sections, tables, and figures that are included in the  
template.  For more information and to register, see .  
ITRC Site Investigation and Remediation for Munitions  
Response Projects - December 6.  State and tribal regulatory  
officials are routinely required to evaluate DOD cleanup strategies  
with little, if any, environmentally oriented munitions response  
experience or guidance.  State regulators are increasingly being  
charged with oversight responsibility for munitions response  
cleanup projects on other than operational ranges, such as formerly  
used defense sites (FUDS) and base realignment and closure  
(BRAC) sites. This seminar covers the site investigation and site  
remediation process for munitions response sites on other than  
operational ranges. It provides an introduction and overview of the  
processes, tools, and techniques used in investigation and  
remediation. These concepts are illustrated using an example  
munitions response site. For more information and to register,  
see or .  
Perchlorate: Overview of Issues, Status, and Remedial Options  
- December 8.  Improved analytical methodology has increased the  
known extent of perchlorate contamination in the U.S.  A variety  
of remediation technologies are currently commercially available  
and being used for perchlorate remediation. This training, based on  
ITRC's Perchlorate: Overview of Issues, Status, and Remedial  
Options (PERC-1), explains why perchlorate is a hot topic in the  
environmental community including up-to-date information on  
sources, occurrences, toxicity and exposure, regulatory status and  
remediation alternatives.  For more information and to register, see or .  
Documents and Web Resources  
Decision Support Tools (DSTs) Matrix.  DSTs are interactive  
software tools used by decision-makers to help answer questions,  
solve problems, and support or refute conclusions. They can be  
incorporated into a structured decision-making process for
