NEXT PRB ACTION TEAM MEETING

The next PRB Action Team meeting will take place in Albuquerque, New Mexico, during the last week of October 2004. The meeting will take place at the Best Western Winrock Inn, which is located across the street from where the Interstate Technology Regulatory Council (ITRC) plans to meet.

Call participants agreed that the RTDF meeting, which will span 1½ days, will commence on the morning of October 26 and conclude at noon on October 27, 2004. In addition, a small PRB Steering Committee meeting will be held on the evening of October 25, 2004, starting at 7:00 p.m. and ending at 9:00 p.m. If enough interest exists, a poster session will be planned for the evening of October 26, 2004.

The following three topical areas will be explored during the meeting:

• Source treatment for dense non-aqueous phase liquids (DNAPLs) and nanoscale iron applications. John Vidumsky, who has agreed to chair this topical session, said that he knows some people who might be interested in delivering presentations on this topic. For example, he said, Tom Sale will be invited to speak about the zero-valent iron (ZVI) source treatment work he is performing through Colorado State University. Michelle Thomson said that Richard Mach has also been identified as a potential speaker, and that she is waiting to receive abstracts from some additional people. Bob Puls said that John Liskowitz of ARS Technologies, Inc., expressed interest in presenting information about work to address source areas at Department of Defense sites. Tom Krug said that he could identify someone to speak about the work GeoSyntec is performing with emulsified ZVI.



• Alternative media and innovative applications. Krug, who has agreed to chair this session, indicated that he has identified some potential speakers for this topical session. For example, a representative from Adventus Remediation Technologies, Inc., might be willing to deliver a presentation on this topic, and someone from GeoSyntec will be identified to speak about biomulch walls. In addition, Sale will be invited to present information about e-barriers.



• Other laboratory and field studies. No speakers have been identified for this session yet.

Call participants discussed methods for advertising the meeting and emphasized the importance of:

• Distributing a meeting invitation. Christine Hartnett said that ERG plans to send a meeting invitation to the entire PRB Action Team by the end of the week.



• Advertizing the meeting via TechDirect. Puls said that EPA's Jeff Heimerman has agreed to announce the PRB meeting in the September and October issues of TechDirect. The announcement will include a call for abstracts.



• Making sure that ITRC meeting attendees know that the RTDF PRB Action Team meeting is taking place across the street. ERG will communicate with the ITRC meeting planners to explore ways to advertise the PRB meeting to the ITRC membership. In addition, ERG will contact the leaders for the following ITRC Teams: DNAPL, Arsenic in Groundwater, Bioremediation of DNAPL, PRBs, and Radionuclides. ERG will let the Team Leads know that an RTDF meeting is scheduled to take place across the street from the ITRC meeting and that a detailed agenda will be distributed in early October.

ACTION ITEMS

• Puls will contact Bob Gillham to invite him to serve as the chair for the "Other Laboratory and Field Study" session. If Gillham is unavailable, Puls said, he will take on the responsibility of chairing the session.



• The session chairs will continue to identify speakers for the meeting. As part of this effort:




– Puls will forward an email from John Liskowitz (of ARS Technologies) to Vidumsky.

– Krug will identify someone to speak about the emulsified ZVI work that GeoSyntec is performing and let Vidumsky know who has been selected to deliver the presentation.

• Call participants agreed to make an effort to identify sponsors for coffee breaks and refreshments. Krug agreed to contact Adventus and Puls agreed to contact Connelly, GeoSierra, and ARS Technologies to determine whether they are interested in sponsoring the meeting. GeoSyntec and ETI were also identified as possible candidates.



• Vidumsky will invite Tom Sale to participate in the PRB Steering Committee meeting that is scheduled to take place on October 25, 2004.



• ERG will distribute a meeting invitation by the end of the week. In addition, ERG will communicate with ITRC meeting planners and Team Leads to make sure that they are aware that the PRB Action Team has scheduled a meeting across the street from the ITRC meeting.



• ERG will set up the next PRB Steering Committee conference call for September 15, 2004, between 3:00 p.m. and 4:00 p.m. Eastern Daylight Time (EDT).
