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 http://www.itrcweb.org or
http://clu-in.org/studio .
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 http://www.itrcweb.org or http://clu-in.org/studio .
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 http://www.itrcweb.org 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
http://clu-in.org/studio .
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 http://www.itrcweb.org

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 http://clu-in.org/studio .
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 http://www.itrcweb.org or http://clu-in.org/studio .
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
