and ground water. Mention of non-EPA documents or presentations does not constitute a U.S. EPA endorsement of their contents, only an acknowledgment that they exist and may

waste professionals. We will advertise the position as a public service for the CLU-IN audience: 1 Environmental Engineer Position with EPA's Technology
Assessment Branch in Arlington, VA. The duties of this position include the use of environmental engineering knowledge and skill to support Superfund remedial
project managers, other remedy decision makers, and EPA staff with usable cost and performance data for remedies, particularly for innovative technologies.
The position, which will soon be officially announced on , will be open to current and former federal employees, and other 'status' candidates
that will be further defined in the official announcement. For more information, see > Upcoming Live Internet Seminars ITRC Development of Performance Specifications for Solidification/Stabilization - September 8, 2011, 11:00AM-1:15PM EDT (15:00-17:15 GMT). The ITRC
technical and regulatory guidance document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and associated
Internet-based training provide an approach to assist practitioners and regulators with measuring and determining acceptable S/S performance. This approach
developed by the ITRC Solidification/Stabilization Team provides information for developing, testing, and evaluating appropriate site-specific performance
specifications and the considerations for designing appropriate long-term stewardship programs. In addition, the approach provides useful tools for establishing
an appropriate degree of treatment and regulatory confidence in the performance data to support decision-making. This training and guidance is intended
to be beneficial to anyone involved with CERCLA, RCRA, brownfields, UST or any other regulatory program where S/S has been selected or implemented as a remedial
technology. For more information and to register, see or . Superfund Landfill Methane Potential Assessment - September 14, 2011, 2:00PM-3:15PM EDT (18:00-19:15 GMT). The EPA Office of Superfund Remediation and
Technology Innovation conducted a study in 2010 to explore options for productively utilizing methane emissions from landfills that are placed on the Superfund
National Priorities List. The study included the development of the Landfill Gas Energy Project Assessment Tool, which can be used to aid managers in conducting
their own assessment of the feasibility of installing landfill gas energy projects at landfills. The scope of the Tool will be presented, together with a discussion
of the Fresno Sanitary Landfill in California as a comparison case study by applying the EPA LandGEM and LFGCost models. Both LandGEM and LFGCost are routinely
used by the EPA Landfill Methane Outreach Program. Total landfill gas and methane generation for the Fresno Sanitary Landfill were estimated using LandGEM
version 3.02, released May 12, 2005, which is an automated tool for estimating emission rates from municipal solid waste (MSW) landfills. The model was developed
by the EPA Office of Research and Development-National Risk Management Research Laboratory, and the Clean Air Technology Center. The model results can be
used to estimate the recoverable methane available for a potential LFG energy project. LandGEM can also be used by landfill owners and operators to determine
if a landfill is subject to the control requirements of the federal New Source Performance Standard (NSPS) for new MSW landfills, the emission guidelines for
existing MSW landfills, or the National Emission Standards for Hazardous Air Pollutants (NESHAP) for MSW landfills. In evaluating the economic feasibility
of an LFG energy project at the Fresno Sanitary Landfill, EPA's LFGcost Tool was utilized. This webinar will review the assumptions made in the Tool and the resulting
economic outlook for a potential project at this site. For more information and to register, see . ITRC Phytotechnologies - September 15, 2011, 11:00AM-1:15PM EDT (15:00-17:15 GMT). This training familiarizes participants with ITRC's Phytotechnology
Technical and Regulatory Guidance and Decision Trees, Revised (Phyto-3, 2009). This document provides guidance for regulators who evaluate and make informed
decisions on phytotechnology work plans and practitioners who have to evaluate any number of remedial alternatives at a given site. This document updates
and replaces Phytoremediation Decision Tree (Phyto-1, 1999) and Phytotechnology Technical and Regulatory Guidance Document (Phyto-2, 2001). It has merged
the concepts of both documents into a single document. This guidance includes new, and more importantly, practical information on the process and protocol
for selecting and applying various phytotechnologies as remedial alternatives. For more information and to register, see or
. ITRC In Situ Bioremediation of Chlorinated Ethene - DNAPL Source Zones - September 22, 2011, 11:00AM-1:15PM EDT (15:00-17:15 GMT). Treatment of dissolved-phase
chlorinated ethenes in groundwater using in situ bioremediation (ISB) is an established technology; however, its use for DNAPL source zones is an emerging
application. This training course supports the ITRC Technical and Regulatory Guidance document In Situ Bioremediation of Chlorinated Ethene: DNAPL Source
Zones (BioDNAPL-3, 2008). This document provides the regulatory community, stakeholders, and practitioners with the general steps practitioners and regulators
can use to objectively assess, design, monitor, and optimize ISB treatment of DNAPL source zones. For more information and to register, see

GMT). Three-dimensional (3-D) visualization and analysis is being used with increasing frequency to improve the effectiveness environmental investigation
and cleanup efforts. Many potential users, however, are not readily aware of how visualization and analysis methods can be used to support their projects at
various stages in a project lifecycle, how the software programs really work, what to consider when scoping and procuring services, what to plan for in terms
of costs and schedule, or how to confirm and quality check results. This two-hour seminar will: (1) describe the setup and use of 3-D data visualization systems;
(2) show how visualization and analysis can help resolve a number of common, but critical, issues at environmental cleanup sites; (3) identify best management
practices developed from a broad range of Superfund site 3-D visualization applications; (4) describe quality control procedures when using 3-D visualization
for analyzing existing data in EPA investigations; (5) and present guidelines for contracting 3-D visualization and an
